[0001] The present invention relates to the field of battery recycling, and in particular to a lithium battery shell crushing particle air separation device. Background Art

[0002] At a time when the new energy battery recycling industry is booming, achieving efficient resource processing and safe disposal of used batteries is a core goal of the industry's development; battery shell crushing and air separation are important links in separating metal and non-metallic materials in the recycling process, which are crucial to 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 in advance for electrolytic treatment and crush them, and then consume the active substances inside the battery through electrochemical reactions to eliminate safety hazards.

[0003] However, this electrolytic pretreatment method brings new technical problems: after the battery shell is broken after electrolysis, a lot of electrolyte will adhere to the surface of its fragments. These residual electrolytes increase the weight of the fragments, causing the movement trajectory of the fragments to deviate during air separation, reducing the wind's effect on separating fragments of different materials.

When the first extrusion part and the second extrusion part move upward to reset, the filter press block and the elastic membrane are in a frustum shape as a whole, thereby preventing the elastic membrane from blocking the paddle and prying the filtered debris out of the filter press block. When the sealing valve squeezes the sliding tube downward, the second squeezing portion protrudes downward from the first squeezing portion, causing the upper surface of the agglomerated fragments to be misaligned after the filtration is completed, rather than being a horizontal plane, making it easier for the prying piece to pry the agglomerated fragments.

[0022] The second discharge port 10201 is funnel-shaped, which facilitates the material to fall out of the second discharge port 10201.

[0023] The first extrusion part 10202 and the second extrusion part 10501 are both made of stainless steel, which has good corrosion resistance and high mechanical strength and a long service life.

[0024] The lower surface of each of the paddles 106 is configured to be serrated.

[0025] 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 a fixed rod.

[0026] A groove 20201 is provided on the upper surface of the filter press block 202 , and the diameter of the groove 20201 is larger than the diameter of the second discharge port 10201 ; a water filter groove 20202 is provided on the filter press block 202 , and the water filter groove 20202 is connected to the water collecting chamber 20203 ; the water filter groove 20202 is located in the groove 20201 .

[0027] The elastic membrane 203 is made of fluororubber, which has good wear resistance and corrosion resistance and a long service life.

[0028] The working principle of the above embodiment is as follows: After the battery shell is broken after electrolysis, the fragments are sent into the sliding tube 102 through the screw conveyor in the conveying tube 101. Figure 4 As shown: in the initial state, the first electric push rod 103 is in a 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 an open state, so the debris entering the sliding tube 102 will fall into the filter press block 202 through the funnel-shaped second discharge port 10201. When the visual sensor 1002 in the filter press chamber 1001 detects that a certain amount of debris has 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, and then the sealing valve 105 contacts the second discharge port 10201, and the plug-in block 10502 is inserted into the second discharge port 10201. 201, and then the second discharge port 10201 is sealed through the sealing valve 105, and then the first electric push rod 103 continues to extend downward, and then the sealing valve 105 squeezes 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, and 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 are used to filter the debris accumulated on the filter block 202, and squeeze out the electrolyte adhered to the surface of the debris. And based on the view from top to bottom, in the process of the sliding tube 102 moving downward, as shown in FIG. Figure 4As shown, the motor 108 is started to drive the sealing valve 105 to rotate counterclockwise. After the sealing valve 105 rotates, the plug-in block 10502 on the sealing valve 105 is inserted into the corresponding plug-in groove on the second discharge port 10201, so 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, thereby driving the first extrusion part 10202 and the second extrusion part 10501 The lower part of the toggle piece 106 is used to toggle the debris accumulated on the filter press block 202 to prevent the debris from accumulating in the middle of the filter press block 202 and affecting the subsequent filtration effect; the electrolyte squeezed out from the first extrusion part 10202 and the second extrusion part 10501 The electrolyte will flow into the water collecting chamber 20203 through the filter hole on the filter press block 202, and then be discharged through the drain pipe 201, and the electrolyte will be The electrolyte is recycled, and then the sealing valve 105 is retracted and reset upward by the first electric push rod 103. At this time, the sealing valve 105 releases the squeezing of the sliding tube 102; the second electric push rod 104 contracts and resets, thereby driving the sliding tube 102 to move upward and reset synchronously. In this process, the motor 108 drives the sealing valve 105 and the sliding tube 102 to rotate clockwise, thereby driving the paddle plate 106 on the lower side of the first extrusion part 10202 and the second extrusion part 10501 to rotate clockwise, and then the paddle plate 106 is used to pry the filtered fragments out of the filter block 202, and then the fragments will fall down into the crusher 2 for secondary crushing, and the smaller fragments will be crushed into powdery materials, and then the crushed powdery materials will enter the air separator 3 for air separation, and finally the recyclable powdery materials (such as copper powder, aluminum powder, etc.) that have been air-separated will be discharged through the first discharge port 3001 on the air separator 3.

[0029] Furthermore, considering that when the debris on the surface of the filter block 202 is filtered by the first extrusion part 10202 and the second extrusion part 10501, the electrolyte filtered out 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, Figure 7 As shown: the third electric push rod 206 is in the extended state. At this time, the filter press block 202 is squeezed by the third electric push rod 206 and protrudes upward from the elastic membrane 203. At this time, the filter press block 202 and the elastic membrane 203 are in a truncated cone shape as a whole. When the first squeezing part 10202 and the second squeezing part 10501 move downward to squeeze the filter press block 202, Figure 6 and Figure 7As shown, at this time, the third electric push rod 206 contracts and resets, and the filter block 202 is pressurized 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 as a whole, and then through the elastic membrane 203, the electrolyte filtered out is prevented from overflowing to the outside of the filter block 202, causing the electrolyte to flow downward from the outside of the filter block 202 to 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 as a whole, preventing the elastic membrane 203 from blocking the paddle plate 106 from prying the filtered fragments out of the filter block 202.

[0030] Furthermore, a groove 20201 is provided on the upper surface of the filter press block 202, and the diameter of the groove 20201 is larger than the diameter of the second discharge port 10201. When there is a large amount of electrolyte in the conveying pipe 101, the electrolyte will fall into the groove 20201 through the second discharge port 10201, and then quickly flow into the water collection chamber 20203 from the filter trough 20202; to avoid the filter press block 202 and the elastic membrane 203 being in a truncated cone shape as a whole in the initial state, when a large amount of electrolyte flows into the filter press block 202, the infiltration speed of the filter hole is slow, causing the electrolyte to flow outward from the upper surface of the filter press block 202, and finally flow into the crusher 2, affecting the subsequent crushing and air separation effect.

[0031] Furthermore, considering that the fragments accumulated on the filter press block 202 will clump and stick together after being compressed, resulting in fragments during subsequent crushing, the hardness and adhesion of the clumped fragments will increase the mechanical load of the crushing equipment, accelerate the wear rate of vulnerable parts such as cutters and screens, shorten the service life of the equipment, and increase maintenance costs; therefore, during the upward movement and reset of the first extrusion part 10202 and the second extrusion part 10501, the sliding tube 102 will drive the prying piece 106 to rotate, thereby gradually separating the fragments clumped on the surface of the filter press block 202, and then dispersing the fragments that are clumped and stuck together.

[0032] Furthermore, considering that the fragments on the surface of the filter block 202 are pressed and agglomerated, the surface of the agglomerated fragments is a horizontal plane, and the contact surface between the toggle piece 106 and the agglomerated fragments is also a horizontal plane, which makes it difficult for the toggle piece 106 to toggle the agglomerated fragments. Therefore, when the sealing valve 105 squeezes the sliding tube 102 downward, the second extrusion portion 10501 protrudes downward from the first extrusion portion 10202, thereby causing the lower surfaces of the first extrusion portion 10202 and the second extrusion portion 10501 to be misaligned. Therefore, after the filtration is completed, the upper surface of the agglomerated fragments will also be misaligned, rather than a horizontal plane, and the lower surface of the toggle piece 106 is also serrated, so that the filter block 202 can be toggled by the serrated toggle piece 106. The fragments on the surface of the agglomerated fragments are prevented from being dispersed by the tossing piece 106, and the contact surface of the tossing piece 106 with the agglomerated fragments and the surface of the agglomerated fragments are all horizontal surfaces, which makes it difficult for the tossing piece 106 to toss the agglomerated fragments, and considering that the filter press block 202 is connected to the elastic membrane 203, when the tossing piece 106 to toss the agglomerated fragments on the surface of the filter press block 202, the filter press block 202 will be pressurized and vibrate, which makes it difficult for the tossing piece 106 to effectively disperse the fragments. Therefore, in the process of the first extrusion part 10202 and the second extrusion part 10501 moving upward and resetting, the third electric push rod 206 will be synchronously extended upward, thereby driving the filter press block 202 to move upward synchronously, avoiding the filter press block 202 from shaking, and ensuring the dispersion effect of the tossing piece 106.

[0033] On the basis of the above technical effects, the present invention also has the following advantages: like Figure 3 As shown, a sealing cover 204 is fixed between the filter press block 202 and the fixed block 205 to prevent debris from falling onto the upper surface of the fixed block 205.

[0034] like Figure 5 As shown: the first extrusion part 10202 and the second extrusion part 10501 are both made of stainless steel, which has good corrosion resistance and high mechanical strength and a long service life.

[0035] like Figure 6 As shown: the elastic membrane 203 is made of fluororubber, which has good wear resistance and corrosion resistance and a long service life.

[0036] Example 2: Based on Example 1, Figure 4 As shown, a second stirring blade 107 is also included; 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 an annular array inside the sliding tube 102.

[0037] The working principle of the above embodiment is as follows: When a large amount of debris enters the sliding tube 102, the wet debris tends to stick together and form a mass, and at the same time adhere to the inner wall of the sliding tube 102, causing the sliding tube 102 to be blocked. Figure 4As shown: During the upward movement of the sliding tube 102, the sliding tube 102 rotates, which drives the second stirring piece 107 to rotate. At this time, the first stirring piece 10302 and the second stirring piece 107 rotate relative to each other, thereby moving the debris in the sliding tube 102 to prevent the debris from accumulating and clumping in the sliding tube 102, causing the sliding tube 102 to be blocked.

Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
