[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5 This utility model provides a plastic scrap washing device, comprising:

[0033] Cleaning tank 1 includes:

[0034] The tank body 11 is used to hold cleaning water. The cleaning tank 1 is connected to the sewage treatment equipment through a drain pipe 114 fixedly opened at the lower end.

[0035] The lid 12 is attached to the upper part of the can body 11 with a movable clip, and a handle 123 is fixedly installed on it;

[0036] The cleaning basket 13 is installed inside the tank body 11 and is used to hold plastic scraps to be cleaned. Its outer side is densely covered with sieve holes for screening and cleaning impurities.

[0037] The scrubbing assembly 2, used to scrub the plastic debris inside the cleaning basket 13, includes:

[0038] The drive motor 21 is fixedly mounted on the can lid 12;

[0039] A drive shaft 22 is rotatably mounted on the tank cover 12 and extends into the cleaning basket 13. The drive shaft 22 is fixedly connected to the power output end of the drive motor 21, and multiple main cleaning brushes 28 are fixedly mounted on its outer side.

[0040] Auxiliary component 3 is used to pump high-pressure air into the tank body 11.

[0041] In practical application, plastic scraps are placed in a cleaning basket 13 and then placed inside a tank 11. Water and detergent are injected into the tank 11, and the lid 12 is then fastened onto the tank 11. The drive motor 21 is started to rotate the drive shaft 22, which in turn brushes the plastic scraps with multiple main cleaning brushes 28 on the drive shaft 22. The rotation and stirring of the drive shaft 22 in conjunction with the main cleaning brushes 28 causes the plastic waste to move within the cleaning basket 13. Impurities are filtered out through the sieve holes on the cleaning basket 13 and discharged through the drain pipe 114. This process is repeated several times to clean the plastic scraps. During the cleaning of the plastic scraps, high-pressure air is pumped into the tank 11 through the auxiliary component 3. This generates bubbles in the tank 11, causing the cleaning water in the tank 11 to move irregularly, thus rinsing and cleaning the plastic scraps in the cleaning basket 13.

[0042] In this embodiment, the drive motor 21 drives the drive shaft 22 to rotate, which in turn drives the main cleaning brush 28 to scrub and clean the plastic fragments. The cleaning basket 13 filters out the impurities. Then, the auxiliary component 3 pumps air into the tank 11 to drive the cleaning water to rinse the plastic fragments and assists the main cleaning brush 28 in stirring to further improve the cleaning effect. Compared with existing plastic fragment cleaning equipment, the cleaning effect is better and the operation is simpler.

[0043] Please see Figure 3 In a preferred embodiment of this utility model, a plurality of retaining plates 111 are fixedly provided on the upper end of the can body 11, and a plurality of buckles 121 adapted to the retaining plates 111 are fixedly provided in the can lid 12 at the position corresponding to the retaining plates 111. The retaining plates 111 and the buckles 121 are movably engaged. A sealing ring 122 is also fixedly provided in the can lid 12. The sealing ring 122 is pressed against the upper end of the can body 11, and the retaining plates 111 and the buckles 121 are fixed by frictional resistance.

[0044] In practical application, the lid 12 is mounted on the body 11, and the handle 123 is rotated to engage the buckle 121 with the plate 111. The sealing ring 122 presses the upper end of the body 11 to achieve a sealed fixation between the body 11 and the lid 12. This prevents the connection stability between the body 11 and the lid 12 from affecting the stirring effect inside the cleaning basket 13 when the drive motor 21 drives the drive shaft 22 to rotate. This ensures the stirring and washing effect.

[0045] Please see Figure 3 As another preferred embodiment of the present invention, a support ring 112 is fixedly provided on the inner wall of the tank body 11, and a slot 113 adapted to the end of the cleaning basket 13 is fixedly provided in the support ring 112 corresponding to the end of the cleaning basket 13, and the end of the cleaning basket 13 is movably locked in the slot 113.

[0046] In practical application, this embodiment uses the set support ring 112 and the slot 113 to achieve the positioning and locking of the cleaning basket 13 under its own weight, and the loading and unloading of plastic scraps is convenient based on the movable locking of the cleaning basket 13.

[0047] Please see Figure 2 and Figure 5 In another preferred embodiment of this utility model, the scrubbing assembly 2 further includes:

[0048] The toothed ring 24 is fixedly installed inside the can lid 12;

[0049] Driven shaft 23 is installed parallel to drive shaft 22 inside can cover 12 and is limited in movement by retainer 27. Its lower end extends into cleaning basket 13. Multiple auxiliary cleaning brushes 29 are fixedly installed on its outer side. The auxiliary cleaning brushes 29 and main cleaning brushes 28 have the same structure. The auxiliary cleaning brushes 29 and main cleaning brushes 28 are arranged alternately.

[0050] The driving gear 25 is fixedly mounted on the driving shaft 22, and through the driven gear 26 fixedly mounted on the driven shaft 23, it meshes with the gear ring 24 and the driving gear 25 to form a planetary gear transmission structure.

[0051] In practical application, this embodiment utilizes a planetary gear transmission structure formed by the meshing of the gear ring 24, the driving gear 25, and the driven gear 26. When the drive motor 21 drives the drive shaft 22 to rotate, the driving gear 25, fixedly mounted on the drive shaft 22, drives the driven gear 26 to rotate around the driven shaft 23 while simultaneously revolving around the drive shaft 22. This, in conjunction with the auxiliary cleaning brush 29 mounted on the driven shaft 23 and the main cleaning brush 28, improves the cleaning effect on the plastic debris in the cleaning basket 13.

[0052] Please see Figure 2 and Figure 4In another preferred embodiment of the present invention, the auxiliary component 3 includes an air pump 31, which is fixedly installed on the side of the tank body 11. Its output end is fixedly connected to an input channel 33 located in the bottom interlayer of the tank body 11 via a connecting hose 32. The input channel 33 is connected to the tank body 11 via an air outlet 331.

[0053] In practical application, the external air is pressurized by the air pump 31 and then transmitted through the connecting hose 32 and the input channel 33 to the tank body 11 via the air outlet 331, forming bubbles and thus driving the flow of cleaning water inside the tank body 11 to achieve a rinsing effect.

[0054] Please see Figure 1 and Figure 2 In another preferred embodiment of the present invention, the auxiliary component 3 further includes a connecting valve 34 installed on the cleaning tank 1, the connecting valve 34 connecting the internal and external environments of the cleaning tank 1.

[0055] In practical application, this embodiment uses the connecting valve 34 to balance the internal air pressure and the external air pressure of the cleaning tank 1, thereby ensuring that the air pump 31 can continuously pump gas into the tank body 11 and ensure that the cleaning work is carried out stably and continuously.

[0056] In one embodiment, during use, the air pump 31 can be replaced with a dual-purpose air-liquid pump and connected to a clean water pipeline. While ensuring the pumping of gas, the automatic pumping of clean water can also be achieved through the control equipment, thereby reducing manual operation and improving the equipment's processing efficiency.

[0057] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
