[0023] Beneficial effects of the present invention:

[0024] (1) During operation, the friction inner shell is rotated through the first rotating shaft, so that the friction blocks on the inner side wall of the friction outer cover and the outer side wall of the friction inner shell rub and friction the fragments of the waste lead-acid battery shell, causing the stains on the surface of the fragments of the waste lead-acid battery shell to separate from themselves and disperse in the guiding liquid. The fragments of the waste lead-acid battery shell and the guiding liquid move along the inner wall of the friction outer cover to the upper surface of the filtering inclined cylinder. The filtering inclined cylinder makes the guiding liquid with stains fall on the sewage draining inclined cylinder. The sewage draining inclined cylinder drains away the guiding liquid with stains and conducts centralized treatment. The fragments of the waste lead-acid battery shell continue to move along the upper surface of the filtering inclined cylinder and repeat the above process between each pair of friction outer covers and friction inner shells until they are discharged from the bottom of the lowermost friction outer cover. Thus, through continuous repeated rubbing and timely separation, various difficult-to-separate stains can also be thoroughly cleaned;

[0025] (2) During operation, the driving motor drives the first rotating shaft and the second rotating shaft to rotate. The second rotating shaft drives each sewage discharging outer cylinder, sewage draining inclined cylinder and sewage discharging inner cylinder to rotate through the transmission gear and transmission tooth ring, so that the transmission ring groove rotates, and then the pushing convex block sequentially and cyclically pushes the transmission roller. The transmission frame is reset through the through spring, and the transmission frame pushes each through needle rod to penetrate each filtering hole reciprocally, preventing the filtering holes from being blocked and guiding the guiding liquid carrying stains, so that the guiding liquid carrying stains flows to the sewage draining inclined cylinder. Through the relative movement of the sewage draining inclined cylinder and the second scraper, the upper surface of the sewage draining inclined cylinder is scraped to prevent stains from adhering, thereby preventing the guiding liquid from being blocked and reducing the flow rate, ensuring that the transmission efficiency of the stains remains within a certain range, and performing self-cleaning during operation, extending each working cycle. By timely draining away the guiding liquid with stains, it is avoided that the stains reattach to the fragments of the waste lead-acid battery shell. Through continuous multiple rubbing and friction, and draining away the sewage synchronously with the rubbing and friction, the fragments of the waste lead-acid battery shell are continuously cleaned multiple times, maintaining the cleanliness of the final obtained product, avoiding secondary treatment, and the structural characteristics of the friction outer cover and the friction inner shell extend the proportion of the rubbing and friction duration in the working process duration, improving the cleaning ability and having the ability to clean the fragments of the waste lead-acid battery shell in complex situations;

[0026] (3) During operation, the liquid storage tank stores the guiding liquid. The circulating water pump inputs the guiding liquid into the water supply pipe. The guiding liquid enters the water supply cavity, and then is split into each support ring groove through the communication holes, and then enters the split flow ring pipe through the communication hose. Finally, it is evenly sprayed on the surface of the waste lead-acid battery shell fragments passing below through each water outlet hole, flushing away the stains, and pushing the waste lead-acid battery shell fragments to continuously move along the upper surface of the filtering inclined cylinder. The guiding liquid with stains flows onto the sewage discharge inclined cylinder, and then flows along the liquid collection annular groove and the liquid collection pipe to the bottom of the liquid storage tank. Under the action of gravity and sedimentation, the stains are deposited at the bottom of the liquid storage tank, and the clean guiding liquid passes through the filter screen plate and is circulated and pushed by the circulating water pump, forming a complete circulating flow of the guiding liquid, continuously guiding the stains to the bottom of the liquid storage tank for precipitation. Due to the action of gravity and sedimentation, the stains will not block the filter screen plate. At the same time, when the stains are enriched to a certain extent, the bottom of the liquid storage tank is opened, and the waste can be quickly emptied by the push of the stored guiding liquid, reducing the maintenance time and maintenance difficulty, thereby further improving the overall working efficiency;

[0027] (4) During operation, through the setting of the support spring, the friction inner shell can rotate and oscillate up and down in the friction outer cover. By oscillating up and down, the rubbing and friction effects on the waste lead-acid battery shell fragments are improved, and at the same time, the wear of the friction blocks is reduced. The oscillation is transmitted and supported through the support collar, the support collar is limited and transmitted through the transmission slide rod, and the shielding collar is used to prevent the guiding liquid and the waste lead-acid battery shell fragments from entering between the transmission components, thereby further improving the cleaning effect of rubbing and friction, reducing the loss amount of the friction components, and extending the overall working life.

Specific implementation mode

[0036] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation mode, structure, features and their effects of the present invention as follows.

[0037] Please refer to Figure 1-6 As shown in the figure: A friction cleaning machine for recycling the outer shell of waste lead-acid batteries includes a working bracket 101. A plurality of friction outer covers 102 are installed in the middle of the working bracket 101. The friction outer covers 102 are arranged vertically at equal intervals and coaxially and are hermetically connected to each other. A first rotating shaft 103 is provided at the axis of the friction outer cover 102. Friction inner shells 104 are installed on the outer periphery of the first rotating shaft 103 and within each friction outer cover 102. A plurality of friction blocks 109 are installed on the inner side wall of the friction outer cover 102 and the outer side wall of the friction inner shell 104. A filter inclined cylinder 108 is embedded and installed at the lower part of the friction outer cover 102. A sewage discharge inclined cylinder 107 is provided below the filter inclined cylinder 108. The middle part of the filter inclined cylinder 108 is lower than the outer periphery in height, and the middle part of the sewage discharge inclined cylinder 107 is higher than the outer periphery in height. A sewage discharge outer cylinder 105 is installed on the outer periphery of the sewage discharge inclined cylinder 107, and a sewage discharge inner cylinder 106 is installed on the inner periphery of the sewage discharge inclined cylinder 107;

[0038] During the operation of this embodiment, the friction outer cover 102 is kept fixed, and the fragments of the waste lead-acid battery case and the guiding liquid are conveyed from the top into the uppermost friction outer cover 102. The guiding liquid reduces the resistance of the fragments of the waste lead-acid battery case during the downward movement. The guiding liquid can be water or other liquids. By rotating the friction inner shell 104 through the first rotating shaft 103, the friction blocks 109 on the inner side wall of the friction outer cover 102 and the outer side wall of the friction inner shell 104 rub and friction the fragments of the waste lead-acid battery case, so that the stains on the surface of the fragments of the waste lead-acid battery case are separated from themselves and dispersed in the guiding liquid. The fragments of the waste lead-acid battery case and the guiding liquid move along the inner wall of the friction outer cover 102 to the upper surface of the filtering inclined cylinder 108. The filtering inclined cylinder 108 makes the guiding liquid with stains fall on the sewage discharging inclined cylinder 107. The sewage discharging inclined cylinder 107 discharges the guiding liquid with stains and conducts centralized treatment. The fragments of the waste lead-acid battery case continue to move along the upper surface of the filtering inclined cylinder 108 and repeat the above process directly between each pair of the friction outer cover 102 and the friction inner shell 104 until they are discharged from the bottom of the lowermost friction outer cover 102. By timely discharging the guiding liquid with stains, the reattachment of the stains to the fragments of the waste lead-acid battery case is avoided. Through continuous rubbing and friction for multiple times, and discharging the sewage synchronously with the rubbing and friction, the fragments of the waste lead-acid battery case are cleaned continuously for multiple times, the cleanliness of the final product is maintained, secondary treatment is avoided, and the structural characteristics of the friction outer cover 102 and the friction inner shell 104 extend the proportion of the rubbing and friction time in the working process time.

[0039] On one side of the working support 101, there is a liquid storage tank 201. Inside the lower part of the liquid storage tank 201, a filter screen plate 202 is installed. A circulating water pump 203 is installed on the filter screen plate 202. On one side of the liquid storage tank 201, a liquid collecting pipe 204 is installed. A plurality of sewage discharge holes 215 are formed in the sewage discharge inclined cylinder 107. Each of the sewage discharge holes 215 is evenly distributed in a circular array on the outer periphery of the sewage discharge inclined cylinder 107. Below the sewage discharge holes 215, there is a liquid collecting annular groove 205. The liquid collecting annular groove 205 is rotatably connected to the sewage discharge inclined cylinder 107 through a connecting ring 216. Each liquid collecting annular groove 205 is communicated with the liquid collecting pipe 204. The output end of the circulating water pump 203 is provided with a water supply pipe 206. A water supply cavity 207 is formed inside the first rotating shaft 103. The upper outer periphery of the first rotating shaft 103 is hermetically and rotatably connected with a liquid guiding annular groove 208. On the outer periphery of the first rotating shaft 103 and located inside each friction inner shell 104, a supporting annular groove 209 is hermetically sleeved. Both the supporting annular groove 209 and the liquid guiding annular groove 208 are communicated with the water supply cavity 207 through a plurality of communication holes 210 formed in the first rotating shaft 103. At the inner bottom of the friction inner shell 104, a flow dividing ring pipe 212 is installed. The flow dividing ring pipe 212 is connected with the corresponding supporting annular groove 209 through a communicating hose 211. A plurality of water outlet holes 213 evenly distributed in a circular array are formed at the bottom of the flow dividing ring pipe 212. The water outlet holes 213 penetrate through the bottom side wall of the friction inner shell 104. A plurality of first scraping plates 214 evenly distributed in a circular array are installed on the lower surface of the bottom of the friction inner shell 104. The first scraping plates 214 form an angle with the radial axis of the bottom surface of the friction inner shell 104. The first scraping plates 214 are made of soft materials;

[0040] When this embodiment works, the liquid storage tank 201 stores a guiding liquid. The circulating water pump 203 inputs the guiding liquid into the water supply pipe 206. The guiding liquid is input into the water supply cavity 207, and then is divided into each supporting annular groove 209 through the communication holes 210, and then is input into the flow dividing ring pipe 212 through the communicating hose 211. Finally, it is evenly sprayed on the surface of the waste lead-acid battery shell fragments passing by below through each water outlet hole 213, washing away the stains and pushing the waste lead-acid battery shell fragments to continuously move along the upper surface of the filtering inclined cylinder 108. The guiding liquid with stains flows onto the sewage discharge inclined cylinder 107, and then flows to the bottom of the liquid storage tank 201 along the liquid collecting annular groove 205 and the liquid collecting pipe 204. Under the action of gravity and sedimentation, the stains are deposited at the bottom of the liquid storage tank 201. The clean guiding liquid passes through the filter screen plate 202 and is circulated and pushed by the circulating water pump 203, forming a complete circulating flow of the guiding liquid, continuously guiding the stains to the bottom of the liquid storage tank 201 for precipitation. Due to the action of gravity and sedimentation, the stains will not block the filter screen plate 202. At the same time, when a certain degree of enrichment is reached, the bottom of the liquid storage tank 201 is opened, and the stored guiding liquid can be quickly emptied by its pushing force.

[0041] A driving motor 301 is installed on the top of the working support 101, and a second rotating shaft 302 is installed on the working support 101 and on one side of the friction outer cover 102. Both ends of the driving shaft of the driving motor 301 are driven by the first rotating shaft 103 and the second rotating shaft 302 through mutually meshing bevel gears. A transmission gear ring 304 is provided on the outer peripheral fixed sleeve of the sewage discharge outer cylinder 105, and a plurality of transmission gears 303 are provided on the fixed sleeve of the second rotating shaft 302. The transmission gears 303 and the transmission gears 303 are connected to each other. The movable gear rings 304 correspond to each other and mesh with each other. The top of the sewage discharge outer cylinder 105 and the top of the sewage discharge inner cylinder 106 are both equipped with a transmission ring groove 305. A plurality of push protrusions 306 are evenly distributed in a ring array in the transmission ring groove 305. The outer and inner peripheries of the filter inclined cylinder 108 are sleeved with positioning rings 307, and the inner and outer peripheries of the filter inclined cylinder 108 are sealed and fixedly connected with the friction outer cover 102 through the positioning rings 307. The filter inclined cylinder 108 is provided with a plurality of push protrusions 306. There are a plurality of filter holes 308, each of which is divided into a plurality of groups. Each group of filter holes 308 is evenly distributed in a circular array. A transmission frame 310 is provided directly below each group of filter holes 308. Both ends of the transmission frame 310 are slidably connected to limit rods 309. The limit rods 309 are correspondingly fixedly connected to the positioning ring 307. Through springs 312 are provided between the two ends of the transmission frame 310 and the corresponding positioning ring 307. A plurality of through springs 312 are installed on each transmission frame 310. The needle rod 311 corresponds to the filter hole 308 one by one. The lower parts of both ends of the transmission frame 310 are equipped with transmission rollers 313. The transmission rollers 313 correspond to the transmission ring groove 305, and the transmission rollers 313 are rollingly connected with the transmission ring groove 305 and the push protrusion 306. The middle part of the transmission frame 310 is equipped with a second scraper 314, which is made of soft material and abuts against the upper surface of the sewage discharge inclined cylinder 107.

[0042] When the present embodiment is working, the driving motor 301 drives the first rotating shaft 103 and the second rotating shaft 302 to rotate, and the second rotating shaft 302 pushes each sewage discharge outer cylinder 105, sewage discharge inclined cylinder 107 and sewage discharge inner cylinder 106 to rotate through the transmission gear 303 and the transmission gear ring 304, so that the transmission ring groove 305 rotates, and then the pushing protrusion 306 pushes the transmission roller 313 in sequence and reciprocatingly, and the transmission frame 310 is reset through the through spring 312, and the transmission frame 310 pushes each through needle rod 311 to reciprocate through each filter hole 308 to avoid the filter hole 308 from being blocked, and guides the diversion liquid carrying stains, so that the diversion liquid carrying stains flows to the sewage discharge inclined cylinder 107, and the upper surface of the sewage discharge inclined cylinder 107 is scraped by the relative movement of the sewage discharge inclined cylinder 107 and the second scraper 314 to avoid the adhesion of stains, thereby preventing the diversion liquid from being blocked and reducing the flow.

[0043] Supporting collar rings 401 are fixedly sleeved on both the inner circumference of the top and the inner circumference of the bottom where the friction inner shell 104 abuts against the first rotating shaft 103. The supporting collar rings 401 are slidably connected to the outer circumference of the first rotating shaft 103. A plurality of groups of transmission sliding rods 402 are fixedly connected to the outer circumference of the first rotating shaft 103 at the positions of the respective supporting collar rings 401. Each group of transmission sliding rods 402 is evenly distributed in a circular array. The transmission sliding rods 402 are parallel to the axial direction of the first rotating shaft 103. The transmission sliding rods 402 are fitted and slidably connected to the supporting collar rings 401. A plurality of groups of supporting springs 403 are provided between the supporting collar rings 401 and the supporting ring grooves 209. Each group of supporting springs 403 is evenly distributed in a circular array. A corrugated tube 405 is fixedly connected to the outer circumference of the supporting collar ring 401. The corrugated tube 405 is fixedly connected to a shielding collar ring 404. The shielding collar ring 404 is fixedly sleeved on the first rotating shaft 103;

[0044] When this embodiment works, due to the arrangement of the supporting springs 403, the friction inner shell 104 can rotate and oscillate up and down inside the friction outer cover 102. By oscillating up and down, the kneading and friction effects on the fragments of the waste lead-acid battery shell are improved, and at the same time, the wear of the friction blocks 109 is reduced. The oscillation transmission and support are carried out through the supporting collar rings 401. The supporting collar rings 401 are limited and driven by the transmission sliding rods 402. The shielding collar ring 404 prevents the diversion liquid and the fragments of the waste lead-acid battery shell from entering between the transmission components.

[0045] When the present invention is in use, the staff rotates the friction inner shell 104 through the first rotating shaft 103, so that the friction blocks 109 on the inner side wall of the friction outer cover 102 and the outer side wall of the friction inner shell 104 form a kneading and friction effect on the fragments of the waste lead-acid battery shell, so that the stains on the surface of the fragments of the waste lead-acid battery shell are separated from themselves and dissipated in the diversion liquid. The fragments of the waste lead-acid battery shell and the diversion liquid move along the inner wall of the friction outer cover 102 to the upper surface of the filtering inclined cylinder 108. The filtering inclined cylinder 108 makes the diversion liquid with stains fall on the sewage discharge inclined cylinder 107. The sewage discharge inclined cylinder 107 discharges the diversion liquid with stains and conducts centralized treatment. The fragments of the waste lead-acid battery shell continue to move along the upper surface of the filtering inclined cylinder 108 and repeat the above process directly between each pair of the friction outer cover 102 and the friction inner shell 104 until they are discharged from the bottom of the lowermost friction outer cover 102. Thus, through continuous and repeated kneading and timely separation, various stains that are difficult to separate can also be thoroughly cleaned;

[0046] During operation, the driving motor 301 drives the first rotating shaft 103 and the second rotating shaft 302 to rotate. The second rotating shaft 302 drives each sewage discharge outer cylinder 105, sewage discharge inclined cylinder 107 and sewage discharge inner cylinder 106 to rotate through the transmission gear 303 and the transmission gear ring 304, so that the transmission ring groove 305 rotates, and then the top push bump 306 sequentially and reciprocally pushes the transmission roller 313. The transmission frame 310 is reset through the through spring 312, and the transmission frame 310 pushes each through needle rod 311 to reciprocally penetrate each filtering hole 308, preventing the filtering holes 308 from being blocked and guiding the flow of the guiding liquid carrying stains, so that the guiding liquid carrying stains flows onto the sewage discharge inclined cylinder 107. Through the relative movement of the sewage discharge inclined cylinder 107 and the second scraper 314, the upper surface of the sewage discharge inclined cylinder 107 is scraped to prevent stains from adhering, thereby preventing the guiding liquid from being blocked and reducing the flow rate, ensuring that the transmission efficiency of the stains is maintained within a certain range, and performing self-cleaning while working, extending each working cycle. By timely discharging the guiding liquid with stains, the reattachment of stains to the fragments of the waste lead-acid battery shell is avoided. Through continuous rubbing and friction, and the simultaneous discharge of sewage during rubbing and friction, the fragments of the waste lead-acid battery shell are continuously cleaned multiple times, maintaining the cleanliness of the final product, avoiding secondary treatment. The structural characteristics of the friction outer cover 102 and the friction inner shell 104 extend the proportion of the rubbing and friction time in the working process duration, improving the cleaning ability and having the ability to clean the fragments of the waste lead-acid battery shell in complex situations;

[0047] During operation, the liquid storage tank 201 stores the guiding liquid. The circulating water pump 203 inputs the guiding liquid into the water supply pipe 206, and the guiding liquid is input into the water supply cavity 207. Subsequently, it is diverted to each support ring groove 209 through the communication holes 210, then input into the shunt ring pipe 212 through the communication hose 211, and finally evenly sprayed on the surface of the passing waste lead-acid battery shell fragments below through each water outlet hole 213, flushing away the stains and pushing the waste lead-acid battery shell fragments to continuously move along the upper surface of the filtering inclined cylinder 108. The guiding liquid with stains then flows onto the sewage discharge inclined cylinder 107, and then is guided to the bottom of the liquid storage tank 201 along the liquid collection annular groove 205 and the liquid collection pipe 204. Under the action of gravity and sedimentation, the stains are deposited at the bottom of the liquid storage tank 201, and the clean guiding liquid passes through the filter mesh plate 202 and is circularly pushed by the circulating water pump 203, forming a complete circular flow of the guiding liquid, continuously guiding the stains to the bottom of the liquid storage tank 201 for precipitation. Due to the action of gravity and sedimentation, the stains will not block the filter mesh plate 202. At the same time, when the stains are enriched to a certain extent, the bottom of the liquid storage tank 201 is opened, and it can be quickly emptied by the push of the stored guiding liquid, reducing the maintenance time and maintenance difficulty, thereby further improving the overall working efficiency;

[0048] During operation, due to the provision of the support spring 403, the friction inner shell 104 can rotate and oscillate up and down within the friction outer cover 102. The up-and-down oscillation improves the kneading and friction effects on the broken pieces of the waste lead-acid battery shell, while reducing the wear of the friction block 109. The oscillation is transmitted and supported through the support collar 401, and the support collar 401 is limited and transmitted through the transmission slide rod 402. The shielding collar 404 prevents the diversion liquid and the broken pieces of the waste lead-acid battery shell from entering between the transmission components, thereby further improving the cleaning effect of kneading and friction, reducing the loss of the friction components, and extending the overall working life.
