The hot washing tank is a piece of equipment mainly used in PET bottle recycling lines to improve the reuse of waste plastics by immersing them in a high-temperature environment to effectively soften and remove impurities and contaminants adhering to the surface.
hot washing tank main applications
Hot wash tanks are generally suitable for processing various plastic types such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and others.
The plastic scrap washing machine is especially suitable for the cleaning of small, medium, and large chemical fiber factories. It can be a fully closed structure according to the process needs.
PET bottle hot washing machine workflow
- Preheating stage: First, the hot washing tank heats the water or steam to a certain temperature, usually above 50 degrees Celsius, by means of a heating system.
- Immersion cleaning: After the water temperature reaches a certain level, the waste plastics are put into the hot wash tank for immersion cleaning. The high-temperature water or steam softens and melts the impurities, contaminants, and residues adhering to the surface of the plastic.
- Physical agitation: In order to increase the cleaning effect, hot washing tanks are usually designed with an agitation or tipping device to enhance the cleaning process through physical agitation, ensuring that each part is fully exposed to the cleaning medium.
- Discharge and cooling: When the cleaning is complete, the waste plastic is removed from the hot wash tank, and the cleaning medium is discharged through a discharge system. Sometimes it is also necessary to cool the wastewater to ensure that the discharge meets environmental standards.
- Drying: The washed plastics may contain some moisture and therefore need to be dried in a subsequent step to ensure that they are suitable for further reprocessing.
Advantages of PET flakes hot washers
- Efficient cleaning: The hot wash tank uses hot water or steam for cleaning, which can quickly soften and remove impurities, grease, and other pollutants adhering to the surface of plastics, and improve the cleaning efficiency.
- Comprehensively applicable: The hot washing tank is applicable to a wide range of plastic raw materials, including polyethylene, polypropylene, etc., so it has strong versatility in processing different types of waste plastics.
- Fast heat transfer: The plastic flakes hot washing machine can raise the water temperature to 90-100 degrees Celsius quickly.
- Low maintenance cost: PET bottle flakes hot washer machines usually have a relatively simple structure and relatively low maintenance cost, making it easy to perform routine maintenance and upkeep.
three types of waste plastic washing machine
There are two other types of plastic washers sold by Shuliy, including friction washers as well as plastic film rinsing tanks, and the main difference between them is the cleaning principle and the way they work.
- The hot washing tank softens and cleans the impurities adhering to the plastic by heating water or a cleaning medium.
- Frictional washers utilize mechanical agitation and friction to remove surface contaminants.
- Plastic rinsing tanks, on the other hand, are specifically designed to clean plastic films, using specific tank structures and working principles.
As a result, these three types of equipment differ in their cleaning methods and applicable scenarios.
