[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

The various technical features of this utility model can be combined interactively without contradicting each other.

[0033] Reference Figure 1 This utility model embodiment proposes a diaphragm cleaning line, which can clean and recycle the diaphragms of waste lithium batteries, effectively separating the metal foil and battery powder mixed on the diaphragm for subsequent recycling and avoiding waste of resources.

[0034] In this embodiment, the diaphragm cleaning line includes a cleaning assembly 100, a dewatering machine 200, and a centrifuge 300. The cleaning assembly 100 includes a grinding and washing machine 110, a rinsing tank 120, and a material extraction machine 130. The cleaning assembly 100 cleans the diaphragm, achieving separation and recycling of the diaphragm and metal foil during the cleaning process. The cleaned diaphragm is then transferred to the dewatering machine 200 for dehydration and recycling, while the wastewater used for cleaning the diaphragm is transferred to the centrifuge 300 for centrifugal separation, thus recovering the battery powder.

[0035] In this embodiment, the grinding and washing machine 110 performs strong scrubbing on the diaphragm. The outlet end of the grinding and washing machine 110 is connected to the inlet end of the rinsing tank 120. Through the cleaning by the grinding and washing machine 110, the battery powder and metal foil adhering to the diaphragm are removed from the diaphragm, and the material enters the rinsing tank 120 from the outlet end of the grinding and washing machine 110 for rinsing.

[0036] Understandably, the inlet and outlet ends of the rinsing tank 120 are respectively located at both ends along the length of the rinsing tank 120. After the material enters from the inlet end of the rinsing tank 120, it moves along the length of the rinsing tank 120 and is rinsed and settled. Since the diaphragm is generally made of polyethylene material, it can float on the water surface, while the metal foil will settle to the bottom, and the battery powder is generally mixed in the middle of the water. During the movement of the material in the rinsing tank 120, the diaphragm, metal foil, and battery powder can achieve the effect of stratification.

[0037] In this embodiment, a discharge port is provided at the upper part of the outlet end of the rinsing tank 120, which is connected to the inlet end of the dewatering machine 200. The dewatering machine 200 can dehydrate and recycle the diaphragm at the upper part of the rinsing tank 120. A drain outlet is provided in the middle of the outlet end of the rinsing tank 120, which is connected to the inlet end of the centrifuge 300. The centrifuge 300 centrifuges and separates the wastewater discharged from the drain outlet, thereby separating the battery powder mixed in the water and realizing the recycling of battery powder. A settling port is provided at the bottom of the outlet end of the rinsing tank 120, which is connected to the inlet end of the material extractor 130. The material extractor 130 can extract the metal foil settled at the bottom of the rinsing tank 120, thereby realizing the recycling of metal foil.

[0038] In some embodiments, the cleaning assembly 100 is provided in multiple sets, and the multiple sets of cleaning assemblies 100 are arranged sequentially. The discharge port of the rinsing tank 120 of the previous set of cleaning assemblies 100 is connected to the inlet end of the grinding and washing machine 110 of the next set of cleaning assemblies 100. The diaphragm after being cleaned by the previous set of cleaning assemblies 100 enters the next set of cleaning assemblies 100 for scrubbing and rinsing. The discharge port of the rinsing tank 120 of the cleaning assembly 100 located at the end is connected to the inlet end of the dewatering machine 200.

[0039] Understandably, by having the diaphragm undergo multiple cleaning processes before entering the dehydrator 200 for dehydration and recycling, it is possible to ensure that the content of metal foil fragments and battery powder mixed in the diaphragm is below the standard, or even zero. This can greatly improve the recovery rate of metal foil and battery powder, and ensure the cleanliness of the diaphragm.

[0040] In this embodiment, the cleaning assembly 100 is provided in two sets. The metal foil, being dense, sinks quickly. After being cleaned by the primary grinding and washing machine 110 and rinsed in the rinsing tank 120, it has essentially settled. The two-stage rinsing tank 120 removes any remaining trace amounts of metal foil, achieving complete separation of the metal foil and the separator. The separator contains minimal battery powder. After cleaning by the primary grinding and washing machine 110 and rinsing in the rinsing tank 120, the battery powder on the separator has largely detached. During the second cleaning, the water in the rinsing tank 120 is already quite clear, and this second rinsing ensures that no battery powder remains in the separator. Therefore, through the dual cleaning by the two sets of cleaning assemblies 100, the separator meets the recycling standards, and the recovery rate of both the metal foil and battery powder is high.

[0041] Understandably, the drain outlet of the rinsing tank 120 in each set of cleaning components 100 is connected to the inlet end of the centrifuge 300 via a pipe or trench.

[0042] In this embodiment, the rinsing tank 120 has a depth of 3 meters or more, which ensures that the diaphragm will not settle to the bottom of the rinsing tank 120 during the rinsing process, and that the stratification between the diaphragm and the metal foil is clear.

[0043] In some embodiments, the centrifuge 300 is provided with a water outlet, and the diaphragm cleaning line also includes a first pump body 400, the inlet end of the first pump body 400 being connected to the water outlet, and the outlet end of the first pump body 400 being connected to the rinsing tank 120.

[0044] It is understandable that the water separated by centrifuge 300 is free of battery powder. The battery powder is discharged from the outlet of centrifuge 300 as filter residue. The separated water can be returned to the rinsing tank 120 by the action of the first pump 400 to replenish the water in the rinsing tank 120, thereby realizing the recycling of water resources and reducing the waste of water resources.

[0045] In this embodiment, the outlet end of the first pump body 400 is connected to two rinsing tanks 120 through pipes, which can return water to the two rinsing tanks 120.

[0046] In some embodiments, refer to Figure 2The grinding and washing machine 110 includes a housing 111, a spiral 112, and a rotary drive component 113. The housing 111 is a hollow structure that extends at an angle. The inlet end of the grinding and washing machine 110 is located at the lower end of the housing 111, and the outlet end of the grinding and washing machine 110 is located at the upper end of the housing 111. The spiral 112 is located inside the housing 111 and extends along the extension direction of the housing 111. The output end of the rotary drive component 113 is drivenly connected to the spiral 112.

[0047] The material enters the interior of the housing 111 from the lower end of the housing 111. Under the driving action of the rotary drive component 113, the spiral 112 can rotate inside the housing 111 and disturb the material inside the housing 111. While the material moves upward along the housing 111, it achieves the effect of washing the material, thereby separating the separator, metal foil and battery powder from each other.

[0048] In some embodiments, the spiral 112 includes a rotating shaft and multiple fan blades. The output end of the rotary drive component 113 is connected to the rotating shaft, which extends along the extension direction of the housing 111. The multiple fan blades are arranged along the extension direction of the rotating shaft. The rotary drive component 113 can drive the rotating shaft to rotate, and the fan blades can rotate with the rotation of the rotating shaft. Through the rotation of the multiple fan blades, the material can be propelled to move upward along the inclined direction of the housing 111 to the outlet end of the washing machine 110. The arrangement of multiple fan blades allows for more comprehensive cleaning of the material and ensures that the material has sufficient power to move upward.

[0049] Furthermore, the spiral directions of two adjacent fan blades are set in opposite directions. The fan blades with opposite spiral directions are used to push the material to move upward or downward along the shell 111, respectively. The spiral angle of the fan blade used to push the material to move upward is greater than the spiral angle of the fan blade used to push the material to move downward.

[0050] With this configuration, as the material moves from the lower end of the housing 111 to the upper end of the housing 111, the bidirectional force generated by the simultaneous rotation of the two sets of fan blades with opposite spiral directions makes the cleaning process of the diaphragm in the housing 111 not only unidirectional cleaning, but also produces a bidirectional rubbing effect, effectively improving the cleaning quality of the diaphragm.

[0051] Understandably, since the helical angle of the fan blade used to push the material to move upward is greater than the helical angle of the fan blade used to push the material to move downward, the overall direction of material movement is upward, which can ensure that the material moves smoothly from the lower end of the housing 111 to the upper end of the housing 111.

[0052] In other embodiments, the rotary drive component 113 is configured to alternately rotate in both directions, allowing the material to move upward a certain distance while simultaneously moving in the opposite direction, achieving a bidirectional washing effect. Furthermore, the time taken for the rotary drive component 113 to drive the fan blades and propel the material upward is greater than the time taken to propel the material downward, ensuring both effective cleaning and the ability for the material to move from the lower end to the upper end of the housing 111.

[0053] In this embodiment, the rotary drive component 113 is a motor, and its output end transmits power to the rotating shaft through belt drive or gear drive.

[0054] In some embodiments, refer to Figure 3 The upper part of the rinsing tank 120 is provided with multiple material feeding rollers 121. The multiple material feeding rollers 121 are arranged along the length of the rinsing tank 120 and are rotatably connected to the rinsing tank 120. Under the rotation of the material feeding rollers 121, the material located at the upper part of the rinsing tank 120 can move from the inlet end of the rinsing tank 120 to the discharge port.

[0055] Understandably, the feeding roller 121 can push the diaphragm located on the upper part of the rinsing tank 120 toward the discharge port, thereby improving the rinsing efficiency and speeding up the movement of the diaphragm to the next washing machine 110 or dewatering machine 200, thus accelerating the diaphragm separation efficiency.

[0056] In some embodiments, a discharge screw 122 is provided at the bottom of the rinsing tank 120. The discharge screw 122 extends along the length of the rinsing tank 120. The discharge screw 122 is rotatably connected to the rinsing tank 120 and can push the material at the bottom of the rinsing tank 120 toward the settling port.

[0057] Understandably, the discharge screw 122 can push the metal foil located at the bottom of the rinsing tank 120 toward the settling port, thereby accelerating the efficiency of the metal foil moving toward the feeder 130 and improving the metal foil recycling efficiency.

[0058] In some embodiments, the diaphragm cleaning line further includes a feeder 600, which is disposed between the rinsing tank 120 and the dewatering machine 200. The feeder 600 extends upward at an angle, with its outlet end located at its upper end and its inlet end located at its lower end. The inlet end of the feeder 600 is connected to the discharge port, and its outlet end is connected to the inlet end of the dewatering machine 200. The diaphragms rinsed in the rinsing tank 120 are discharged through the discharge port into the feeder 600 and transported to the inlet end of the dewatering machine 200 by the feeder 600. This solves the problem of a height difference between the discharge port and the inlet end of the dewatering machine 200, preventing direct connection and allowing the diaphragms to smoothly enter the dewatering machine 200 for dewatering.

[0059] In an embodiment with multiple sets of cleaning components 100, a feeder 600 is positioned between the last rinsing tank 120 and the dewatering machine 200, for connecting the discharge port of the last rinsing tank 120 and the inlet of the dewatering machine 200.

[0060] In this embodiment, the feeder 600 is equipped with spiral blades, which are used to transport materials from a low position to a high position. Based on the principle that the spiral rotation propels the material upwards, the spiral blades are driven to rotate by a motor, and the material is gradually conveyed upwards by the frictional force of the spiral blades.

[0061] In some embodiments, the diaphragm cleaning line further includes a ground tank 500 and a second pump body 510, wherein the ground tank 500 is used to store wastewater after rinsing in the rinsing tank 120, the ground tank 500 is connected to the drain outlet through a pipe or a ditch, the inlet end of the second pump body 510 is connected to the ground tank 500 through a pipe, and the outlet end of the second pump body 510 is connected to the inlet end of the centrifuge 300.

[0062] By setting up a second pump body 510 and a ground pool 500, wastewater can enter the centrifuge 300 more smoothly for centrifugal separation, so as to facilitate the recovery of battery powder.

[0063] In some embodiments, the dehydrator 200 utilizes centrifugal force to expel water from the diaphragm. The dehydrator 200 consists of a machine body, a dehydration drum, a motor, a braking device, and a drainage system. The motor drives the dehydration drum to rotate at high speed, subjecting the diaphragm to a great centrifugal force, causing the water in the diaphragm to be expelled and discharged from the machine, thereby achieving the dehydration effect.

[0064] The working principle of the diaphragm cleaning line in this embodiment of the invention is as follows: A diaphragm doped with metal foil and battery powder enters the diaphragm cleaning line from the inlet end of the abrasive mill 110 in the first set of cleaning components 100. The diaphragm is rubbed and washed by the blades of the first abrasive mill 110 and moves upward to the outlet end of the abrasive mill 110. The battery powder and metal foil adhering to the diaphragm are separated from the diaphragm by the abrasive action of the first abrasive mill 110 and enter the rinsing tank 120 of the first set of cleaning components 100. The diaphragm, metal foil and battery powder are rinsed and separated into layers in the rinsing tank 120. The metal foil settles to the bottom of the rinsing tank 120 and moves to the settling port under the action of the discharge screw 122. The metal foil is then extracted by the feeder 130. The diaphragm floats on the top of the rinsing tank 120 and moves to the discharge port under the action of the feed roller 121, and enters the grinding machine 110 of the next set of cleaning components 100. The battery powder flows with the rinsing water to the drain and flows into the ground pool 500 along the pipe or trench.

[0065] The diaphragm entering the second washing machine 110 is further scrubbed and then rinsed in the second rinsing tank 120. The diaphragm, metal foil, and battery powder are further separated in the second rinsing tank 120. The metal foil settles to the bottom of the rinsing tank 120 and moves to the settling port under the action of the discharge screw 122. The metal foil is then extracted and recycled by the extractor 130. The diaphragm floats on the upper part of the rinsing tank 120 and moves to the discharge port under the action of the feeding roller 121, and then enters the dewatering machine 200. The battery powder flows with the rinsing water to the drain and flows along the pipe or trench to the ground pool 500.

[0066] The dewatering machine 200 dehydrates and recycles the diaphragm. Wastewater entering the ground tank 500 is pumped into the centrifuge 300 by the second pump 510 for centrifugal separation. Battery powder is discharged from the centrifuge 300 as filter residue, while the water after separating the battery powder is returned to the two rinsing tanks 120 by the first pump 400 for reuse.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
