Description

Technical Field

[0001] This invention relates to the field of battery recycling, and more particularly to a lithium battery casing crushing particle air separation device. Background Technology

[0002] With the booming development of the new energy battery recycling industry, achieving efficient resource utilization and safe disposal of waste batteries is the core goal of the industry's development. Battery casing crushing and air separation are important steps in the recycling process to separate metal and non-metal materials, which are crucial for improving resource recovery rates and reducing processing costs. Since the residual chemical substances inside new energy batteries are flammable and explosive, in order to prevent safety accidents such as explosions and fires during the crushing process, existing technologies usually place the batteries in an electrolytic cell for electrolytic treatment and crush them, thereby consuming the active materials inside the battery through electrochemical reactions to eliminate safety hazards.

[0003] However, this electrolytic pretreatment method brings new technical problems: after the battery casing is broken, a lot of electrolyte will adhere to the surface of the fragments. This residual electrolyte increases the weight of the fragments, causing the fragment movement trajectory to deviate during wind separation and reducing the wind's separation effect on fragments of different materials. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology where a lot of electrolyte adheres to the surface of the fragments after the battery casing is broken, which increases the weight of the fragments and affects the air separation effect, the present invention provides an air separation device for crushed lithium battery casing particles.

[0006] As a further preferred embodiment, the drive assembly includes a first electric push rod, a sealing valve, and a motor; the first electric push rod is fixedly connected inside the conveying pipe; a connecting roller is fixedly connected to the output end of the first electric push rod; a motor is fixedly connected to the lower side of the connecting roller; the sealing valve is rotatably connected to the output end of the motor; an insertion block is provided on the sealing valve; an insertion slot is provided on the second discharge port; a second extrusion section is provided on the lower side of the sealing valve; and several actuating plates arranged in a ring array are also fixedly connected to the lower side of the second extrusion section.

[0007] As a further preferred embodiment, the filter press assembly includes a drain pipe, a filter press block, a sealing cover, and a fixing block; a fixing block is fixedly connected to the lower side of the filter press chamber; the filter press block is connected to the fixing block, and the diameter of the filter press block is the same as the outer diameter of the sliding tube; a water collection chamber is opened inside the filter press block; a filter hole is opened on the upper side of the filter press block, and the filter hole communicates with the water collection chamber; a drain pipe is fixedly connected to the fixing block; the drain pipe communicates with the water collection chamber and extends outward through the shell; a sealing cover is fixedly connected between the filter press block and the fixing block.

[0008] As a further preferred option, the second discharge port is funnel-shaped.

[0009] As a further preferred option, both the first extrusion section and the second extrusion section are made of stainless steel.

[0010] As a further preferred option, the lower surface of each toggle piece is serrated.

[0011] As a further preferred embodiment, it also includes an elastic membrane and a third electric push rod; the third electric push rod is fixedly connected to the fixed block; the output end of the third electric push rod is fixedly connected to the filter press block; an elastic membrane is fixedly connected to the outside of the filter press block; the elastic membrane is fixedly connected to the inner wall of the filter press chamber through the fixed rod.

[0012] As a further preferred embodiment, the upper surface of the filter press block is provided with a groove, and the diameter of the groove is larger than the diameter of the second discharge port; a water filter trough is provided on the filter press block, and the water filter trough is connected to the water collection chamber; the water filter trough is located in the groove.

[0013] As a further preferred option, the elastic membrane is made of fluororubber.

[0014] As a further preferred embodiment, it also includes a second agitator; a plurality of first agitators are fixedly attached to the connecting roller; and a plurality of second agitators are arranged in a ring array inside the sliding tube.

[0015] The present invention has the following advantages: by pushing the sealing valve and sliding tube downward through the first electric push rod, the battery shell fragments that fall onto the filter press block are filtered and discharged and collected through the drain pipe. This solves the problem in the prior art that after the battery shell is broken by electrolysis, a lot of electrolyte will adhere to the surface of the fragments. This residual electrolyte increases the weight of the fragments, causing the fragment movement trajectory to deviate during air separation and reducing the separation effect of wind on fragments of different materials.

[0016] When the first electric push rod pushes the sealing valve and sliding tube downward, the motor drives the sealing valve and sliding tube to rotate counterclockwise, which in turn drives the agitator to rotate counterclockwise. The agitator then moves the debris accumulated on the filter block to prevent the debris from accumulating in the middle of the filter block and affecting the subsequent filtration effect.

[0017] When the first electric push rod pushes the sealing valve and sliding tube to move upward and reset, the motor drives the sealing valve and sliding tube to rotate clockwise, which in turn drives the agitator to rotate clockwise, pushing the filtered fragments out of the filter block. At the same time, the serrated agitator gradually separates the clumps of fragments, thus breaking up the clumps of fragments that are stuck together.

[0018] When the first and second extrusion sections move downward to extrude pressure on the filter block, the filter block and the elastic membrane are in a basin shape, thus preventing the filtered electrolyte from overflowing to the outside of the filter block. When the first and second extrusion sections move upward to reset, the filter block and the elastic membrane are in a frustum shape, thus preventing the elastic membrane from blocking the actuating plate from pushing the filtered fragments out of the filter block.

[0019] When the sealing valve pushes the sliding tube downwards, the second pressing part will bulge downwards from the first pressing part, causing the upper surface of the agglomerated fragments to become misaligned instead of a horizontal plane after the filter press is completed. This makes it easier for the agitator to move the agglomerated fragments. Attached Figure Description

The drain pipe 201 is fixedly connected to the fixing block 205. The drain pipe 201 communicates with the water collection chamber 20203, and the drain pipe 201 extends outward from the housing 1. The sealing cover 204 is fixedly connected between the filter press block 202 and the fixing block 205.

[0035] The second discharge port 10201 is funnel-shaped, which facilitates the material to fall out of the second discharge port 10201.

[0036] Both the first extrusion section 10202 and the second extrusion section 10501 are made of stainless steel, which has good corrosion resistance and high mechanical strength, and a long service life.

[0037] The lower surface of each toggle piece 106 is serrated.

[0038] It also includes an elastic membrane 203 and a third electric push rod 206; the third electric push rod 206 is fixedly connected to the fixed block 205; the output end of the third electric push rod 206 is fixedly connected to the filter press block 202; the elastic membrane 203 is fixedly connected to the outside of the filter press block 202; the elastic membrane 203 is fixedly connected to the inner wall of the filter press chamber 1001 through the fixed rod.

[0039] The filter press block 202 has a groove 20201 on its upper surface, and the diameter of the groove 20201 is larger than the diameter of the second discharge port 10201; the filter press block 202 has a water filter trough 20202, which is connected to the water collection chamber 20203; the water filter trough 20202 is located in the groove 20201.

[0040] The elastic membrane 203 is made of fluororubber, which has good wear resistance and corrosion resistance and a long service life.

[0041] The working principle of the above embodiments is as follows:

[0042] After the battery casing is broken following electrolysis, the fragments are fed into the sliding tube 102 via a screw conveyor inside the conveying pipe 101. Figure 4 As shown: In the initial state, the first electric push rod 103 is in the retracted state, and the sealing valve 105 is not in contact with the second discharge port 10201. At this time, the second discharge port 10201 is in the open state. Therefore, the fragments entering the sliding tube 102 will fall onto the filter press block 202 through the funnel-shaped second discharge port 10201. When the vision sensor 1002 in the filter press chamber 1001 detects that a certain amount of fragments have accumulated on the upper surface of the filter press block 202, the first electric push rod 103 is activated to push the sealing valve 105 downward. Then, the sealing valve 105 contacts the second discharge port 10201, and the plug block 10502 is inserted into the second discharge port 10201. In the corresponding insertion slot on 201, the second discharge port 10201 is sealed by the sealing valve 105. Then, the first electric push rod 103 continues to extend downward, and then the sealing valve 105 will squeeze the sliding tube 102 downward. At this time, the second electric push rod 104 is pulled downward and extends, and the sliding tube 102 moves downward. Then, the first squeezing part 10202 on the lower side of the sliding tube 102 and the second squeezing part 10501 on the lower side of the sealing valve 105 will squeeze the debris accumulated on the filter block 202, squeezing out the electrolyte adhering to the surface of the debris. And taking the view from top to bottom as a reference, during the downward movement of the sliding tube 102, as Figure 4As shown, the motor 108 is started, driving the sealing valve 105 to rotate counterclockwise. After the sealing valve 105 rotates, the plug block 10502 on the sealing valve 105 is inserted into the corresponding plug slot on the second discharge port 10201. Therefore, the sealing valve 105 will drive the sliding tube 102 to rotate counterclockwise. At this time, the sliding tube 102 rotates on the rotating ring 10203, which in turn drives the actuating plate 106 at the bottom of the first extrusion part 10202 and the second extrusion part 10501 to rotate counterclockwise. The actuating plate 106 then moves the debris accumulated on the filter block 202, preventing the debris from accumulating in the middle of the filter block 202 and affecting the subsequent filtration effect. The electrolyte squeezed out by the first extrusion part 10202 and the second extrusion part 10501 flows into the water collection chamber 20203 through the filter holes on the filter block 202, and then is discharged through the drain pipe 201. The solution is recycled, and then the sealing valve 105 is retracted upwards and reset by the first electric push rod 103. At this time, the sealing valve 105 releases the pressure on the sliding tube 102. The second electric push rod 104 retracts and resets, thereby driving the sliding tube 102 to move upwards and reset synchronously. During this process, the motor 108 drives the sealing valve 105 and the sliding tube 102 to rotate clockwise, thereby driving the actuating plate 106 on the lower side of the first extrusion part 10202 and the second extrusion part 10501 to rotate clockwise. The actuating plate 106 pushes the filter-pressed fragments out of the filter block 202, and then the fragments fall downwards into the crusher 2 for secondary crushing, breaking the smaller fragments into powder. The crushed powder then enters the air classifier 3 for air classification. Finally, the recyclable powder (such as copper powder, aluminum powder, etc.) after air classification is discharged through the first discharge port 3001 on the air classifier 3.

[0043] Furthermore, considering that when the fragments on the surface of the filter block 202 are filtered by the first extrusion section 10202 and the second extrusion section 10501, the filtered electrolyte also overflows to the outside of the filter block 202, causing the electrolyte to flow downward from the outside of the filter block 202 into the crusher 2, affecting the subsequent crushing and air separation effect; in the initial state, if Figure 7 As shown: the third electric push rod 206 is in the extended state. At this time, the filter block 202 is squeezed by the third electric push rod 206 and protrudes upward from the elastic membrane 203. At this time, the filter block 202 and the elastic membrane 203 are in a frustum shape. When the first squeezing part 10202 and the second squeezing part 10501 move downward to squeeze the filter block 202, at this time... Figure 6 and Figure 7As shown, at this time, the third electric push rod 206 retracts and resets, the filter block 202 is pressed and protrudes downward from the elastic membrane 203. At this time, the filter block 202 and the elastic membrane 203 are in a basin shape. The elastic membrane 203 prevents the electrolyte from overflowing to the outside of the filter block 202, which would cause the electrolyte to flow downward from the outside of the filter block 202 into the crusher 2, affecting the subsequent crushing and air separation effect. When the first extrusion part 10202 and the second extrusion part 10501 move upward and reset, the filter block 202 and the elastic membrane 203 are in a frustum shape, preventing the elastic membrane 203 from blocking the actuating plate 106 from pushing the filtered fragments out of the filter block 202.

[0044] Furthermore, a groove 20201 is provided on the upper surface of the filter block 202, and the diameter of the groove 20201 is larger than the diameter of the second discharge port 10201. When there is a lot of electrolyte in the conveying pipe 101, the electrolyte will fall into the groove 20201 through the second discharge port 10201, and then flow quickly into the water collection chamber 20203 from the water filtration tank 20202. This avoids the filter block 202 and the elastic membrane 203 being in a frustum shape in the initial state. When a lot of electrolyte flows into the filter block 202, the slow permeation speed of the filter holes will cause the electrolyte to flow outward from the upper surface of the filter block 202 and eventually flow into the crusher 2, affecting the subsequent crushing and air separation effect.

[0045] Furthermore, considering that the fragments accumulated on the filter press block 202 will clump together under pressure, causing the hardness and adhesion of the clumped fragments to increase the mechanical load on the crushing equipment during subsequent crushing, the wear rate of vulnerable parts such as blades and screens will accelerate, shorten the service life of the equipment, and increase maintenance costs; therefore, during the upward movement and resetting of the first extrusion section 10202 and the second extrusion section 10501, the sliding tube 102 will drive the agitator 106 to rotate, thereby gradually removing the clumped fragments on the surface of the filter press block 202 and dispersing the clumped fragments.

[0046] Furthermore, considering that the fragments on the surface of the filter block 202 agglomerate under pressure, and that the surface of the agglomerated fragments is horizontal, and the contact surface between the agitator 106 and the agglomerated fragments is also horizontal, making it difficult for the agitator 106 to move the agglomerated fragments, when the sealing valve 105 presses the sliding tube 102 downward, the second pressing part 10501 will protrude downward from the first pressing part 10202, thereby causing the lower surfaces of the first pressing part 10202 and the second pressing part 10501 to misalign. Therefore, after filtration, the upper surface of the agglomerated fragments will also be misaligned, instead of being a horizontal surface, and the lower surface of the agitator 106 is also serrated, thus the filter block 202 is moved by the serrated agitator 106. To prevent the agitator 106 from contacting the agglomerated fragments and the surface of the agglomerated fragments from being horizontal, which would make it difficult for the agitator 106 to move the agglomerated fragments, and considering that the filter block 202 is connected to the elastic membrane 203, when the agitator 106 moves the agglomerated fragments on the surface of the filter block 202, the filter block 202 will be compressed and shake, making it difficult for the agitator 106 to effectively disperse the agglomerated fragments. Therefore, during the upward movement and resetting of the first extrusion part 10202 and the second extrusion part 10501, the third electric push rod 206 will extend upward synchronously, thereby driving the filter block 202 to move upward synchronously, avoiding the filter block 202 from shaking and ensuring the dispersion effect of the agitator 106.

[0047] In addition to the above-mentioned technical effects, the present invention also has the following advantages:

[0048] like Figure 3 As shown: A sealing cover 204 is fixed between the filter press block 202 and the fixing block 205 to prevent fragments from falling into the upper surface of the fixing block 205.

[0049] like Figure 5 As shown: The first extrusion section 10202 and the second extrusion section 10501 are both made of stainless steel, which has good corrosion resistance and high mechanical strength, and a long service life.

[0050] like Figure 6 As shown: Elastic membrane 203 is made of fluororubber, which has good wear resistance and corrosion resistance and a long service life.

[0051] Example 2: Based on Example 1, such as Figure 4 As shown, it also includes a second stirring blade 107; a plurality of first stirring blades 10302 are fixedly connected to the connecting roller 10301; and a plurality of second stirring blades 107 are arranged in a ring array inside the sliding tube 102.

[0052] The working principle of the above embodiments is as follows:

[0053] When a large number of fragments enter the sliding tube 102, the moist fragments easily stick together and clump, adhering to the inner wall of the sliding tube 102, causing blockage. Therefore, if... Figure 4 As shown: During the upward movement of the sliding tube 102, the rotation of the sliding tube 102 will drive the second stirring plate 107 to rotate. At this time, the first stirring plate 10302 and the second stirring plate 107 will rotate relative to each other, thereby moving the fragments in the sliding tube 102 and preventing the fragments from accumulating and clumping in the sliding tube 102, which would cause the sliding tube 102 to become blocked.
