[0002] In the field of resource recycling and reuse, the crushing and washing of waste plastics is a key step in realizing their recycling. After crushing and washing, the waste plastics need to have their surface and internal moisture removed before they can enter subsequent processes such as melting and granulation.

[0003] After plastic is crushed (using a crusher) and washed, a large amount of water adheres to the surface of the plastic, so it needs to be air-dried. When the plastic is transported from the washing tank through the conveyor belt, the plastic is concentrated in the middle of the conveyor belt, resulting in uneven thickness of the plastic on the conveyor belt and low subsequent air-drying efficiency. In order to solve the above problems, the inventor proposes a waste plastic crushing and washing equipment. Utility Model Content

[0022] Supporting plates 43 are symmetrically fixedly connected to the top of the mounting base 1 and near the supporting plate 4. An eccentric wheel 44 is rotatably connected between the two supporting plates 43.

[0023] By adopting the above technical solution, the eccentric wheel 44 and the U-shaped water storage box 41 are used together to drive the U-shaped water storage box 41 to shake, which facilitates the disruption of the material on the U-shaped filter plate 42.

A valve is provided on the liquid outlet pipe according to the actual use requirements.

[0024] One of the support plates 2 43 is equipped with a motor 2 45 on its side end. The output end of the motor 2 45 passes through the support plate 2 43 and is fixedly connected to the eccentric wheel 44.

[0025] By adopting the above technical solution, the second working motor 45 is operated, thereby causing the fixedly connected eccentric wheel 44 to rotate.

[0031] By adopting the above technical solution, the protective inclined plate 33 is located on the side of the extrusion roller 32 away from the center of the trapezoidal mounting box 31, which is used to assist the material to fall between the two extrusion rollers 32 for extrusion.

[0032] A conveyor belt 22 is installed between the cleaning tank 2 and the U-shaped support frame 3.

[0033] By adopting the above technical solution, and with the conveyor belt 22 set at an incline, it is convenient to transport the cleaned material to the top of the U-shaped support frame 3.

[0036] Working principle: When using this device, the waste plastic is first crushed by the crusher 11 (the crusher 11 is a mature technology that can be purchased on the market. The structure of the equipment has not been modified in this article. Therefore, those skilled in the art are familiar with its working principle and can apply it skillfully. Therefore, this article will not elaborate on it in detail). After crushing, the plastic falls into the cleaning tank 2 which has a cleaning water source (which can be disinfectant). Then, multiple cleaning rollers 21 are started at the same time to clean the crushed waste plastic. The cleaned waste plastic is then transported by the conveyor belt 22. The waste plastic falls between two extrusion rollers 32. The motor 38 works in conjunction with bevel gear 34 and bevel gear 37 to extrude the waste plastic, thereby removing the moisture inside the waste plastic and improving the dehydration efficiency of the waste plastic.

[0037] The squeezed waste plastic falls into the U-shaped filter plate 42. Then, the working fan 47 and motor 45 are started at the same time, so that motor 45 drives the eccentric wheel 44 to rotate, thereby achieving the effect of shaking the U-shaped filter plate 42 (in conjunction with the support plate 4 and the U-shaped water storage box 41), which can disperse the waste plastic in the U-shaped filter plate 42 (the squeezed waste plastic). The working of the fan 47, in conjunction with the air duct, can make the drying nozzle 46 dry the waste plastic on the U-shaped filter plate 42 (breaking the squeezed waste plastic into a loose state, increasing the contact area with air).

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
