plastic Dewatering Machine is a highly efficient equipment specially used to remove water from plastic materials. It uses centrifugal force to remove water from the surface and inside of the plastic through a high-speed rotating dewatering drum, so that the plastic material reaches a dry state and is ready for subsequent processing or recycling. Its core structure includes motor, control panel, feed hopper, dewatering drum and discharge port, etc., which are usually made of stainless steel to ensure the durability and corrosion resistance of the equipment. In the field of plastic recycling and processing, it can effectively improve production efficiency, reduce labor costs, and ensure that the dryness of plastic materials meets process requirements.

Plastic Dewatering Machine Parameters:

Plastic Dewatering Machine Features:

1. Efficient dehydration performance: The dehydration rate of the Plastic Dewatering Machine can be as high as 97% - 98%. The dehydration drum inside it rotates at high speed, and the centrifugal force generated can forcefully throw out the water in the plastic. Some vertical plastic dehydrators have a drum speed of up to 2000rpm, which can quickly reduce the moisture content of PET plastic bottle flakes from 30% - 40% after washing to 2% - 3%. If a drying tube is installed, the moisture content can be further reduced to 0.5% - 1%.

   
   

2. Accurate temperature and humidity control: Equipped with a high-precision temperature and humidity sensor, it can monitor the temperature and humidity of plastic materials in real time with an accuracy of ±1%. When the humidity exceeds the set value, the machine automatically adjusts the drum speed and the power of the heating device to ensure that the plastic humidity is stable in the ideal range. When processing PP plastics, the humidity can be accurately controlled below 0.5%, and the temperature fluctuation can be controlled at ±1℃ to prevent the performance of the plastic from changing due to abnormal temperature and humidity.

   
   

3. Low energy consumption design: It uses an efficient energy-saving motor with an efficiency of more than 85%, which is 20% - 30% more energy-saving than traditional motors. Through the optimized transmission system and variable frequency speed regulation technology, the motor can run at the most energy-saving speed under different load conditions. Taking a plastic dehydrator with a processing capacity of 1000kg/h as an example, it can save 5-10 degrees of electricity per hour. In the long run, it can save considerable electricity costs for production companies.

   
   

4. High degree of automation: With the help of advanced sensors and intelligent control systems, the automatic feeding system of the machine can accurately control the opening and closing degree of the feed port according to the preset plastic amount and feeding speed, and the error is controlled within ±2%. In the discharging link, the infrared sensing device can automatically identify the accumulation of dry plastics, start the discharging device in time, and transport the dried plastics evenly and smoothly to the designated location. No human intervention is required throughout the process. 5000-10000kg of plastics can be stably processed every day, providing reliable guarantee for large-scale production.

   
   

5. Strong and durable material: High-quality 304 stainless steel is used as the main material. This steel contains 16% - 18% chromium, which can form a dense chromium oxide film on its surface, which can effectively resist the erosion of corrosive substances such as acids and alkalis generated during the dehydration of plastics. Its thickness reaches 3 - 5mm, which can withstand long-term mechanical shock and heavy loads, ensuring the service life of the machine for up to 10 - 15 years.

   
   

6. Excellent noise control: High-performance shock-absorbing pads are installed at the connection between key components such as motors, drums and the machine body, which can effectively absorb the vibration generated during the operation of the machine and reduce the noise generated by the vibration transmitted to the surrounding environment. The special soundproof cover structure is adopted, and the sound insulation effect reaches 20 - 30 decibels, which controls the noise generated by the machine during operation below 70 - 80 decibels, which is far lower than the Chinese industrial noise emission standards, creating a quiet working environment for operators and reducing the harm of noise to the body.

Applications of Plastic Dewatering Machine:

1. Plastic recycling industry: After the waste plastic bottles and plastic packaging are collected and initially crushed and cleaned, they often contain a lot of water and impurities. Plastic Dewatering Machine can remove the moisture to below 2% - 3%, so that the recycled plastics can meet the drying requirements of recycled granulation. For PET plastic bottles, the dehydrated plastics can be directly fed into the recycled granulator to produce high-quality recycled PET particles for the manufacture of new plastic products such as fibers, plastic films, etc., to achieve the recycling of waste plastics, reduce dependence on virgin plastics, and reduce resource waste and environmental pollution.

   
   

2. Injection molding industry: On the injection molding production line, the moisture content of plastic particles such as PP and PE must be strictly controlled within 0.1% - 0.3%, otherwise it will cause defects such as bubbles and warping in the injection molded products. The machine can efficiently dehydrate the injection molding raw materials to ensure that the plastic particles entering the injection molding machine are in the best dry state.

   
   

3. Plastic pipe production field: In the production of various types of plastic pipes, such as PVC pipes, PE pipes, etc., the dryness of the raw plastic directly affects the quality and performance of the pipes. The plastic raw materials processed by the Plastic Dewatering Machine have extremely low moisture content. During the extrusion molding process, the wall thickness of the pipe can be uniform, the strength is high, and there are no pores.

   
   

4. Food packaging plastic industry: Plastic materials used for food packaging have extremely high requirements for hygiene and drying. For example, the plastic film used to package biscuits, candies, etc., its production raw materials need to be strictly dehydrated. This machine can reduce the moisture content of plastic raw materials to an extremely low level, ensuring that during the film blowing, bag making and other processing processes, the plastic film will not produce fog spots, cracks and other problems due to moisture.

   
   

5. Electronic and electrical plastic parts manufacturing: Plastic housings, brackets and other parts in electronic and electrical products need to be produced under high-precision injection molding or molding processes. Plastic Dewatering Machine provides precise dehydration solutions for electronic-grade plastic materials, controlling the moisture content of plastics below 0.05%, avoiding problems such as reduced insulation performance of electronic components and signal interference caused by moisture.

   
   

6. Building plastic products: In the production of building plastic doors and windows, plastic pipes, etc., the drying quality of plastic raw materials is related to the performance and life of the products. This machine can efficiently dehydrate various building plastic raw materials to ensure that the size of plastic products is stable and the strength meets the standards in subsequent processing links such as extrusion and injection molding.

Plastic Dewatering Machine Maintenance:

• Daily cleaning and inspection: After the production is finished every day, first turn off the power of the machine and wait for the equipment to stop running completely. Use a soft brush to gently clean the dust, plastic debris and other debris on the surface of the machine, especially around the feed hopper, discharge port and control panel to prevent debris accumulation from affecting the normal operation of the machine. Check whether the screws on the outside of the machine are loose. If they are loose, tighten them with a wrench in time to ensure the stability of the machine structure. At the same time, observe whether there are scratches or collision marks on the surface of the machine. If any abnormality is found, record it in time and report it to the maintenance personnel for evaluation and treatment to prevent small problems from turning into major failures. Check the sealing performance of the machine regularly to ensure that there is no water or oil leakage at each connection part. If the sealing gasket is found to be aging or damaged, replace it in time.

  
  

• Motor maintenance: Check the running status of the motor every week to check whether the motor has abnormal vibration and noise. Use a vibration meter to measure the vibration amplitude of the motor. If it exceeds 5mm/s, find the cause and solve it in time. Use an infrared thermometer to detect the motor temperature. The normal operating temperature should be controlled below 70℃. Excessive temperature may be caused by motor overload or poor heat dissipation. Remove the motor fan cover every month, clean the dust and oil on the fan blades, and ensure that the motor has good heat dissipation and ventilation. Check the grounding wire of the motor every quarter to see if it is firm. The grounding resistance should be less than 4 ohms to prevent the motor from causing safety accidents. The motor bearing should be filled with lubricating oil every 2000 hours of operation to ensure that the motor runs smoothly and has low noise, extending the service life of the motor.

  
  

• Dehydration drum maintenance: Before production every day, run the dehydration drum idling for 5-10 minutes to observe whether it runs smoothly and whether there are any abnormal sounds. Check the sealing performance of the drum regularly to ensure that the sealing ring is not aged or worn to prevent moisture from penetrating into the motor or transmission system. Clean the inside of the drum once a month, use a special equipment cleaner to thoroughly remove the plastic residue and dirt attached to the inner wall of the drum and the screen, and dry it after cleaning before putting it into use. Check the dynamic balance of the drum every six months. If the dynamic balance deviation exceeds 5g・cm, it needs to be corrected to avoid the vibration of the machine due to the imbalance of the drum, which will affect the dehydration effect and the life of the machine. The mesh aperture of the drum can be customized according to different plastic materials. Generally, the mesh aperture of PET plastic is 1-2mm, and the mesh aperture of PP plastic is 2-3mm, to ensure the best dehydration effect.

  
  

• Transmission system maintenance: Check the tension of the transmission belt every two weeks, press the middle part of the belt with your fingers, and the sinking amount should be within 10-15 mm. If the belt is too loose or too tight, adjust the position of the pulley in time for correction. Observe whether there is wear and cracks on the surface of the belt, and replace it in time if it is damaged. Lubricate the transmission chain once a month, use special chain lubricant, apply it evenly, ensure the chain runs flexibly and reduce wear. At the same time, check the wear of the sprocket. If the sprocket tooth profile is severely worn, replace the sprocket in time to prevent the chain and sprocket from failing to cooperate well and causing transmission failure. The normal operation of the transmission system is the key to ensuring the dehydration efficiency of the machine, and regular maintenance can effectively extend its service life.

  
  

• Maintenance of the control system: Regularly check whether the wiring terminals of the control system are loose, tighten the loose wiring with a screwdriver to ensure reliable electrical connection. Clean the control panel once a month, wipe the display and buttons with a clean damp cloth to remove dust and stains to avoid affecting the operation display. Check whether the connection lines of each sensor are damaged or short-circuited. If there is a problem, repair or replace it in time. Update and optimize the software of the control system once a quarter (if the manufacturer provides update services) to ensure that the control function of the machine is always in the best condition, improve production efficiency and equipment stability. The stable operation of the control system is the basis for the normal operation of the machine, and timely maintenance can avoid downtime caused by electrical failure. Lubrication system management: Establish a detailed lubrication plan and select suitable lubricants for different parts of the machine, such as bearings, gears, etc. For example, for high-speed bearings, use high-temperature and wear-resistant lithium-based grease, add it once every 500 hours of operation, and add 30-50 grams each time. Check whether the oil circuit of the lubrication system is unobstructed and whether there is oil leakage every month, and repair damaged oil pipes and joints in time. Regularly replace the lubricating oil, generally every 6 months, according to the equipment's operating time and the manufacturer's recommendations, to ensure that the lubrication system always provides sufficient lubrication for the key components of the machine, reduce friction and wear, and extend the service life of the machine. Good lubrication is an important guarantee for the normal operation of the machine, and scientific management of the lubrication system can effectively reduce the equipment failure rate.
