Description

Technical Field

[0001] This utility model relates to the field of plastic cleaning technology, and in particular to a friction machine. Background Technology

[0002] To mitigate environmental pollution caused by landfilling or incineration and alleviate the shortage of plastic resources, the large quantities of used plastic infusion bottles and bags generated daily by medical institutions can be collected and recycled through a plastic infusion bottle recycling production line. After the recycled infusion bottles are crushed, impurities such as labels and glue may remain on the fragments. Therefore, a friction cleaning machine is used to remove these impurities through friction and collision between the cleaning water and the plastic fragments. Existing technology, patent number CN215543222U, discloses a plastic friction cleaning machine with a material lifting function. By incorporating a stirring and lifting component, the material is stably conveyed to the left under the action of an auger. The rotation of the first and second blades on the upper and lower sides of the main shaft enables efficient friction cleaning of the material. However, during the cleaning process, plastic fragments are prone to floating or accumulating, resulting in incomplete cleaning. Summary of the Invention

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 4 As shown, this utility model provides a friction machine, including a body 10, a cleaning chamber 11 inside the body 10, a feed inlet 12 communicating with the cleaning chamber 11 at one end of the body 10, a discharge outlet 13 communicating with the cleaning chamber 11 at the bottom of the other end of the body 10, a water spraying mechanism 20 inside the cleaning chamber 11, a friction cleaning mechanism 30 rotatably installed inside the cleaning chamber 11, a filter screen 14 communicating with the cleaning chamber 11 at the bottom of the body 10, a drain pipe 40 communicating with the body 10 below the filter screen 14, and an elastic pressing assembly 50 above the inside of the cleaning chamber 11. The cleaning chamber 11 can be cylindrical; the machine body 10 is inclined upward from the inlet 12 to the outlet 13, that is, the inlet 12 is located above the lower end and the outlet 13 is located below the higher end. During the cleaning process, the material is transported upward, increasing the cleaning time; the filter screen 14 has filter holes smaller than the size of plastic fragments, which can intercept plastic fragments and allow wastewater containing impurities to pass through and be discharged.

[0024] See Figures 2 to 4In one specific embodiment of this application, the elastic pressing assembly 50 includes a pressing plate 51, the top of which is connected to the upper part of the cleaning chamber 11 via a return spring 52. The pressing plate 51 is a plate with a semi-circular cross-section, capable of covering the cylindrical cleaning chamber 11. Located below the water surface, the pressing plate 51 presses floating plastic fragments down into the water, increasing the friction between the plastic fragments and the inner wall of the pressing plate 51 during the cleaning process, resulting in better cleaning. Furthermore, the pressing plate 51 is elastically mounted within the cleaning chamber 11 via the return spring 52, preventing it from obstructing the rotation of the friction cleaning mechanism 30. When plastic fragments are thrown onto the pressing plate 51 by the centrifugal force of the rotating friction cleaning mechanism 30 and press the pressing plate 51 upwards, the pressing plate 51 can also spring back under the action of the return spring, continuing to press down on the plastic fragments. Furthermore, a material-blocking filter plate 53 is provided at the upper part of the inside of the cleaning chamber 11 and at both ends of the pressure plate 51. The material-blocking filter plate 53 is semi-circular in shape and blocks both ends of the pressure plate 51. The material-blocking filter plate 53 can only allow water to flow through and intercepts plastic fragments and debris, reducing the area between the outer wall of the pressure plate 51 and the inner wall of the cleaning chamber 11. In addition, the distance between the two ends of the pressure plate 51 and the inner wall of the material-blocking filter plate 53 is such that plastic fragments cannot enter, while ensuring the smooth movement of the pressure plate 51.

[0025] See Figure 2 The bottom of the sewage discharge cylinder 40 is equipped with an overflow baffle 41 that divides the interior of the sewage discharge cylinder 40 into a sewage discharge area 42 and an overflow area 43. A sewage discharge pipe 44 connecting to the sewage discharge area 42 is also provided at the bottom of the sewage discharge cylinder 40, and an overflow pipe 45 connecting to the overflow area 43 is also provided at the bottom of the sewage discharge cylinder 40. Sewage containing impurities, after being discharged through the filter screen 14, enters the sewage discharge cylinder 40. The overflow baffle 41 performs coarse filtration on the discharged sewage, causing impurities to settle to the bottom. The sewage then overflows through the overflow baffle 41 into the overflow area 43, allowing the impurities and sewage to be discharged through the overflow pipe 45 and the sewage discharge pipe 44 respectively. Control valves can be installed in both the overflow pipe 45 and the sewage discharge pipe 44 to adjust the water output.

[0026] In a specific embodiment of this application, the friction cleaning mechanism 30 includes a stirring cleaning shaft 31 rotatably mounted within the cleaning chamber 11. A drive motor 32, with its drive end connected to one end of the stirring cleaning shaft 31, is provided at one end of the machine body 10. The drive motor 32 drives the stirring cleaning shaft 31 to rotate, thereby agitating the material and performing friction cleaning against the inner wall of the cleaning chamber 11. Specifically, the stirring cleaning shaft 31 has an auger conveyor blade 33 at one end of the inlet 12, and several friction blades 34 are provided between the inlet 12 and the outlet 13. Plastic fragments are conveyed forward and upward by the auger conveyor blades 33 and transported to the friction blades 34 for friction cleaning.

[0027] In a specific embodiment of this application, the water spraying mechanism 20 includes a water spraying pipe 21, which is located on the top of the body 10. The water spraying pipe 21 is provided with multiple sets of water spray heads 22 extending into the cleaning chamber 11. To avoid obstructing water flow, the elastic pressure assembly 50 can be located between two adjacent water spray heads 22.

[0028] After being crushed, the material enters the cleaning chamber 11 through the feed inlet 12 and is pushed forward by the screw conveyor blades 33. At the same time, water is sprayed from the water spray pipe 21 to wash the material. The material is washed by water while being rubbed and propelled by the friction blades. Meanwhile, the elastic pressing component can apply appropriate pressure to the material to prevent it from floating or accumulating during the cleaning process. During this process, the sewage is thrown out from the filter screen, and the cleaned material is discharged from the discharge outlet 13.

[0029] This utility model discloses a friction machine that sprays cleaning water into the cleaning chamber 11 through a water spraying mechanism 20, and uses a friction cleaning mechanism 30 to rub and clean plastic fragments to remove stains from the surface of the plastic fragments. An elastic pressing component 50 is also provided on the upper part of the cleaning chamber. When the plastic fragments move past the elastic pressing component 50, the elastic pressing component 50 can apply appropriate pressure to the material to prevent the material from floating or accumulating during the cleaning process, and ensure that the cleaning effect is uniform.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
