Description

Technical Field

[0001] This invention relates to the field of plastic cleaning technology, and more particularly to a cleaning tank capable of removing foam. Background Technology

[0002] Before sorting out the plastic in old batteries, they need to be placed in a cleaning tank for cleaning. During the cleaning process, a lot of foam will be generated at the top of the cleaning tank. If it is not cleaned, the foam will overflow the tank and affect the surrounding environment.

[0003] Therefore, a heavy plastic sorting and rinsing device can be adopted, for example, as proposed in the utility model patent with application number CN202221855884.5. In this device, the scum scraping component and the suction component work together to continuously push the scum in one direction and quickly suck out the concentrated scum and film through the suction component, thereby achieving rapid cleaning of the rinsing tank surface.

[0004] However, when the pump body generates suction to extract foam, the foam breaks off from the pump body's impeller and ruptures, resulting in cavitation and thus shortening the pump body's lifespan. Summary of the Invention

[0005] In view of this, it is necessary to provide a foam-removing cleaning tank to solve the problem that when foam is extracted by generating suction through the pump body, the foam ruptures the impeller of the pump body, resulting in cavitation and thus shortening the pump body's lifespan.

[0006] This invention provides a defoaming cleaning tank, comprising a cleaning tank body, a defoaming component, and an air extraction component. The defoaming component includes a guide plate and defoaming cotton. The guide plate is fixedly disposed in the cleaning tank body and divides the cleaning tank body into a lower cleaning chamber and an upper processing chamber. The guide plate has multiple guide holes. The defoaming cotton is fixedly disposed on the guide plate and covers the multiple guide holes. The air extraction component has an air extraction end, which is located above the defoaming cotton.

[0007] Furthermore, it also includes a plurality of dividing members corresponding one-to-one with the plurality of flow guide holes, the dividing members being built into the corresponding flow guide holes to divide the foam passing through the flow guide holes.

[0008] Furthermore, the dividing component is a cutting blade, which is fixedly connected to the flow guide hole of the flow guide plate. The cutting edge of the cutting blade is positioned facing the cleaning chamber, and the cutting blade divides the flow guide hole into multiple dividing channels that connect the cleaning chamber and the processing chamber.

[0009] Furthermore, the defoaming component also includes an extrusion plate, which is located on the side of the defoaming cotton away from the guide plate and is slidably connected to the cleaning tank body in a direction close to or away from the defoaming cotton. The extrusion plate is provided with multiple vent holes.

[0010] Furthermore, the defoaming component also includes a driving member connected to the extrusion plate to drive the extrusion plate to slide.

[0011] Furthermore, the plurality of exhaust holes on the extrusion plate are staggered from the plurality of guide holes on the guide plate.

[0012] Furthermore, it also includes multiple plugs corresponding to multiple vent holes one by one. One end of each plug is fixedly connected to the guide plate, and the other end of each plug passes through the defoaming cotton and is positioned towards the corresponding vent hole. Each plug can move with the extrusion plate to a first position and a second position. When the plug moves to the first position, the plug is spaced apart from the corresponding vent hole. When the plug moves to the second position, the plug is engaged in the corresponding vent hole.

[0013] Furthermore, the cleaning pool body includes a pool body and a cover plate, the cover plate being detachably connected to the top of the pool body to open or close the opening at the top of the pool body.

[0014] Furthermore, the guide plate is fixedly connected to the inner wall of the cover plate, and the processing chamber is formed between the guide plate and the cover plate. The air extraction assembly includes an air pump and an air extraction pipe. The air pump is fixedly connected to the cover plate, and the air pump is connected to the processing chamber via the air extraction pipe.

[0015] Furthermore, the bottom of the cover plate is recessed upward to form a conical inner wall, and the air extraction pipe is connected to the center of the top of the cover plate.

[0016] Compared with existing technologies, the plastic in the old battery is introduced into the cleaning chamber of the cleaning tank body for cleaning. During the cleaning process, the cleaning fluid continuously produces foam due to contact with air. The foam spreads upward until it passes through the guide holes of the guide plate and enters the defoaming cotton. As the foam passes through the defoaming cotton, the disordered pores and small pore diameter of the defoaming cotton cause the foam to burst. The gas generated by the bursting foam passes through the defoaming cotton and is sucked away by the suction component above. The cleaning fluid generated by the bursting foam is absorbed by the defoaming cotton and gradually permeates back into the cleaning chamber, avoiding the cavitation phenomenon caused by the bursting foam from damaging the suction component.

[0023] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figure 1-2 As shown, the present invention provides a defoaming cleaning tank, including a cleaning tank body 100, a defoaming component 200, and an air extraction component 300. The defoaming component 200 includes a guide plate 210 and defoaming cotton 220. The guide plate 210 is fixedly disposed in the cleaning tank body 100 and divides the cleaning tank body 100 into a lower cleaning chamber and an upper processing chamber. The guide plate 210 has a plurality of guide holes 211. The defoaming cotton 220 is fixedly disposed on the guide plate 210 and covers the plurality of guide holes 211. The air extraction component 300 has an air extraction end, which is located above the defoaming cotton 220.

[0025] During implementation, the plastic from the old battery is introduced into the cleaning chamber of the cleaning tank body 100 for cleaning. During the cleaning process, the cleaning fluid continuously produces foam due to contact with air. The foam continuously spreads upward until it passes through the guide hole 211 of the guide plate 210 and enters the defoaming cotton 220. As the foam passes through the defoaming cotton 220, the disordered pores and small pore diameter of the defoaming cotton 220 cause the foam to burst. The gas generated by the bursting foam passes through the defoaming cotton 220 and is sucked away by the suction component 300 above. The cleaning fluid generated by the bursting foam is absorbed by the defoaming cotton 220 and gradually permeates back into the cleaning chamber, avoiding damage to the suction component caused by the cavitation phenomenon caused by the bursting foam.

[0026] The cleaning tank body 100 in this embodiment is a structure for cleaning the plastic in old batteries. It is used to hold cleaning fluid. It can be understood that the cleaning tank body 100 can be implemented as a square tank body 110 or a tank body structure. This embodiment of the invention does not limit this.

[0027] In this embodiment, the defoaming component 200 is a structure that eliminates foam during the upward spread of foam. Specifically, the defoaming component 200 includes a guide plate 210 and defoaming cotton 220. The guide plate 210 is fixedly installed in the cleaning tank body 100 and divides the cleaning tank body 100 into a lower cleaning chamber and an upper processing chamber. The guide plate 210 has multiple guide holes 211. The defoaming cotton 220 is fixedly installed on the guide plate 210 and covers the multiple guide holes 211.

[0028] It is understood that foam is generated during the cleaning of plastic. As the plastic is agitated, the cleaning liquid comes into contact with air, forming an air-containing foam structure above the cleaning tank body 100. Therefore, the working principle of the defoaming component 200 in this invention is to break the foam and release the air inside, thereby achieving a gas-water separation process. To this end, defoaming cotton 220 is provided so that as the foam passes through it, the pores in the defoaming cotton 220 divide the foam, causing it to break. The guide plate 210, while supporting the defoaming cotton 220, also has guide holes 211 on it that restrict the upward spread of the foam. The defoaming cotton 220 has a porous structure similar to a sponge layer.

[0029] like Figure 3 As shown, to improve foam elimination capability, multiple dividing members 212 corresponding to the multiple guide holes 211 are also included. The dividing members 212 are built into the corresponding guide holes 211 to divide the foam passing through the guide holes 211. This can realize the pre-treatment function of foam, dividing larger foam into smaller foam, which is convenient for further division by the subsequent defoaming cotton 220.

[0030] like Figure 4 As shown, in one embodiment, the dividing element 212 is a cutting blade, which is fixedly connected to the guide hole 211 of the guide plate 210. The cutting edge of the cutting blade is positioned facing the cleaning chamber, and the cutting blade divides the guide hole 211 into multiple dividing channels connecting the cleaning chamber and the processing chamber. The number of cutting blades can be multiple, and these multiple cutting blades are evenly arranged circumferentially around the central axis of the guide hole 211.

[0031] As the foam continuously breaks down within the defoaming cotton 220, the cleaning fluid generated is continuously absorbed by the defoaming cotton 220, affecting its permeability and reducing its ability to handle foam. Therefore, as... Figure 5-6As shown, the defoaming component 200 also includes a squeezing plate 230. The squeezing plate 230 is located on the side of the defoaming cotton 220 away from the guide plate 210 and is slidably connected to the cleaning tank body 100 in a direction close to or away from the defoaming cotton 220. The squeezing plate 230 has multiple vent holes 231. By moving the squeezing plate 230 towards the defoaming cotton 220, the cleaning liquid in the defoaming cotton 220 can be squeezed out and flowed back into the cleaning chamber through the guide holes 211, which can effectively prevent the loss of cleaning liquid.

[0032] To facilitate the movement of the extrusion plate 230, the defoaming component 200 in this embodiment further includes a driving member 240. The driving member 240 is connected to the extrusion plate 230 and is used to drive the extrusion plate 230 to slide. It is understood that the driving member 240 can be implemented using a structure such as multiple cylinders. The multiple cylinders are evenly arranged around the circumference of the extrusion plate 230, and the output ends of the multiple cylinders are all connected to the extrusion plate 230 to stably push the extrusion plate 230 to move.

[0033] To prevent the cleaning fluid in the defoaming cotton 220 from penetrating the vent holes 231 above it during the extrusion process and then flowing back and reabsorbing into the defoaming cotton 220, in one embodiment, the multiple vent holes 231 on the extrusion plate 230 are staggered from the multiple guide holes 211 on the guide plate 210. The system also includes multiple plugs 213 corresponding to the multiple vent holes 231. One end of each plug 213 is fixedly connected to the guide plate 210, and the other end of each plug 213 passes through the defoaming cotton 220 and points towards the corresponding vent hole 231. The plugs 213 can move with the extrusion plate 230 to a first position and a second position. When the plug 213 moves to the first position, it is spaced apart from the corresponding vent hole 231. When the plug 213 moves to the second position, it is engaged in the corresponding vent hole 231.

[0034] To facilitate inspection and maintenance of the interior of the cleaning tank body 100, in one embodiment, the cleaning tank body 100 includes a tank body 110 and a cover plate 120. The cover plate 120 is detachably connected to the top of the tank body 110 to open or close the opening at the top of the tank body 110. The tank body 110 can be detachably connected via hinges 111 and multiple connecting screws 112. Of course, other connection methods can also be used, and this embodiment of the invention does not limit the specific connection method.

[0035] In one embodiment, the guide plate 210 is fixedly connected to the inner wall of the cover plate 120, forming a processing chamber between the guide plate 210 and the cover plate 120. The suction assembly 300 includes an air pump and a suction pipe. The air pump is fixedly connected to the cover plate 120 and communicates with the processing chamber via the suction pipe. The bottom of the cover plate 120 is concave upwards to form a conical inner wall, and the suction pipe is connected to the center of the top of the cover plate 120. This facilitates the introduction of gas generated by foam bursting into the suction pipe.

[0036] It is understood that the cover plate 120, defoaming component 200 and air extraction component 300 in this embodiment can be easily modified on the existing pool body 110 structure, that is, the cover plate 120 with the defoaming component 200 and air extraction component 300 installed can be added to the pool body 110, which has a wide range of applications.

[0037] Compared with existing technologies: The plastic in the old battery is introduced into the cleaning chamber of the cleaning tank body 100 for cleaning. During the cleaning process, the cleaning fluid continuously produces foam due to contact with air. The foam continuously spreads upward until it passes through the guide hole 211 of the guide plate 210 and enters the defoaming cotton 220. As the foam passes through the defoaming cotton 220, the disordered pores and small pore diameter of the defoaming cotton 220 cause the foam to burst. The gas generated by the bursting foam passes through the defoaming cotton 220 and is sucked away by the suction component 300 above. The cleaning fluid generated by the bursting foam is absorbed by the defoaming cotton 220 and gradually permeates back into the cleaning chamber, avoiding damage to the suction component caused by the cavitation phenomenon caused by the bursting foam.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
