AI Technical Summary
Existing plastic recycling granulators have difficulty cleaning the gaps and corners of irregularly shaped plastics during the cleaning process, resulting in poor cleaning effect and affecting the subsequent granulation quality.
The device employs a combination of spiral blades and a fixed plate for a flipping structure, along with water spraying from a spray pipe for cleaning. The spiral blades push the plastic sheet to move and the fixed plate flips it, while the spray pipe sprays water to achieve thorough cleaning of the plastic sheet.
This improves the cleaning effect of plastic sheets, ensures the quality of subsequent granulation, enables the recycling of water resources, and reduces equipment damage.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic recycling technology, specifically a plastic recycling granulator with a washing and drying device. Background Technology
[0002] Waste plastic recycling involves first cleaning and drying, then melting and plasticizing it using a plastic recycling pelletizer screw before extruding it into strips. After cooling, the strips are cut into pellets by a pelletizer and finally processed into various plastic products through processes such as blow molding, injection molding, and calendering.
[0003] Patent CN205735662U discloses a plastic recycling granulator with a cleaning and drying device, comprising a cleaning chamber, a drying chamber, a crushing chamber, and a material cylinder; the cleaning chamber is the main component of the plastic recycling granulator with the cleaning and drying device; the water spraying device is located at the top inside the cleaning chamber; the plastic inlet is located on the left side outside the cleaning chamber; the drain pipe is located at the bottom of the cleaning chamber; the drying chamber is located on the right side of the cleaning chamber; the conveyor belt is located in the middle of the drying chamber; the crushing chamber is located at the bottom of the cleaning chamber and the drying chamber; and the drive wheel is located in the middle of the crushing chamber.
[0004] This plastic recycling granulator, equipped with a washing and drying device, has a washing chamber and a drying chamber, eliminating the need for washing and drying on other equipment and saving a significant amount of manpower and resources. However, there are still areas for improvement. For example, the device directly sprays water to wash the recycled plastic, but the recycled plastic often has irregular shapes, such as broken plastic bottles and twisted plastic pipes, and is generally quite large. During the simple water spraying process, it is difficult to reach every crevice and corner, resulting in poor cleaning effect and seriously affecting the quality of subsequent recycling granulation, thus failing to meet current needs.

The cleaning tank 301 is fixedly installed on the top of the support frame 1. The rotating shaft 302 is rotatably installed inside the cleaning tank 301. The motor 303 is fixedly installed on the side of the cleaning tank 301. The output shaft of the motor 303 is fixedly connected to the rotating shaft 302. Motor 303 drives shaft 302 to rotate. Spiral blades 304 are fixedly mounted on the surface of shaft 302, and fixing plate 305 is also fixedly mounted on the surface of shaft 302. The spiral blades 304 and fixing plate 305 are alternately arranged on the surface of shaft 302. This arrangement facilitates the movement and rotation of the plastic sheet. Semicircular mesh 306 is fixedly mounted inside cleaning tank 301. Spiral blades 304 and semicircular mesh 306 are tightly fitted together, as are fixing plate 305 and semicircular mesh 306. This arrangement facilitates the movement of the plastic sheet within the semicircular mesh 306. The fixing plate 305 can flip the plastic sheet. The spray pipe 307 is fixedly installed inside the cleaning tank 301. The fixing box 308 is fixedly installed on the side of the cleaning tank 301. The water pump 309 is fixedly installed on the side of the fixing box 308. The water inlet pipe 310 is fixedly installed at the water inlet end of the water pump 309. The side of the fixing box 308 is connected to the cleaning tank 301, and the water inlet pipe 310 is connected to the fixing box 308. This arrangement allows water inside the cleaning tank 301 to reach the inside of the water inlet pipe 310 through the cleaning tank 301. The water outlet pipe 311 is fixedly installed at the water outlet of the water pump 309. At one end, the water outlet pipe 311 is connected to the spray pipe 307. The bottom of the spray pipe 307 has nozzles arranged in a linear array.

[0024] During use, the plastic sheets crushed by the crushing component 2 enter the interior of the cleaning tank 301. The motor 303 is started to drive the rotating shaft 302 to rotate, which allows the spiral blades 304 to push the plastic sheets to move inside the semi-circular mesh 306. At the same time, the fixing plate 305 can flip the plastic sheets. The water pump 309 is started, and the water inside the cleaning tank 301 is sprayed out from the nozzle after passing through the cleaning tank 301, the inlet pipe 310, the outlet pipe 311, and the spray pipe 307. This sprays water onto the moving and flipping plastic sheets, which can better clean the plastic sheets. After cleaning, the plastic sheets pass through the drying component 4 and the granulator body 5 to obtain high-quality plastic granules. The water after cleaning falls back into the interior of the cleaning tank 301, realizing the recycling of water resources. A filter screen 313 is provided to filter impurities and reduce the damage to the water pump 309 caused by impurities. Pulling the connecting plate 312 allows the filter screen 313 to be removed for cleaning.
