Description

Technical Field

[0001] The invention belongs to the technical field of waste lithium battery treatment, and specifically relates to a waste liquid treatment device applicable to the disassembly and recycling of waste lithium batteries. Background Art

[0002] After the waste lithium battery is disassembled and discharged for treatment, waste liquid will be generated. The waste liquid is purified by a waste liquid treatment device. The existing waste liquid pretreatment is to add a flocculant to the waste liquid to agglomerate the fine impurities in the waste liquid. After the impurities settle, the impurities in the waste liquid are separated. The existing separation method usually directly places the water pumping end of the water pump into the impurities settled in the waste liquid for pumping. This pumping method will cause the pumping end to always be in the stratified area of the waste liquid and impurities, resulting in some floating impurities at the stratification being contaminated and attached to the filter screen of the pumping end during the pumping process, thereby causing the filter screen to become blocked, and further leading to a decrease in the pumping efficiency. Operators often need to clean the filter screen repeatedly, reducing the working efficiency of the separation operation.

[0003] Therefore, a waste liquid treatment device applicable to the disassembly and recycling of waste lithium batteries is proposed. Summary of the Invention

[0014] Preferably, an electromagnetic lock III is connected to one side of the circular tube. The locking rod inside the electromagnetic lock III is clamped inside the sleeve and the L-shaped tube.

[0015] Preferably, limiting rods are movably sleeved on both sides of the top end of the inner tube. A second spring is sleeved outside the limiting rods. The two ends of the second spring are respectively connected to the limiting rod and the inner tube. The top end of the limiting rod is connected to a connecting plate above the inner tube.

[0016] Preferably, four water inlet holes are circumferentially opened inside the circular plate. The bottom end of the connecting rod is connected to a cross. Sealing balls that can seal the cross are connected to the four ends of the cross.

[0018] Preferably, water outlet holes are opened on both sides inside the circular plate. A solenoid valve I that can close the circular plate is arranged at the bottom of the circular plate.

[0019] Preferably, a fixed cylinder located below the circular tube is fixedly connected to the outside of the L-shaped tube. Sliding grooves are formed on both sides inside the fixed cylinder. An activity ball that can seal the fixed cylinder is movably sleeved inside the sliding grooves. The other end of the sliding groove is connected to a mesh plate. A third spring is connected between the activity ball and the mesh plate. A pressure sensing element that can abut against the activity ball is installed on one side inside the sliding groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By providing an inner tube, a separation mesh, and a movable tube, the slide bar assembly, the floating ring, the connecting frame, the separation mechanism, and the water diversion mechanism fall to the liquid surface under their own gravity. At this time, the slide bar assembly slides down on the mounting frame and, under the buoyancy of the floating ring, keeps the floating ring, the connecting frame, and the hollow slide bar floating on the liquid surface. At this time, the separation mechanism and the water diversion mechanism sink in the waste liquid under their own gravity, causing the inner tube to drive and descend inside the hollow slide bar. At the same time, the water diversion mechanism drives the movable tube and the sealing plate to descend along the inside of the movable groove. During the descent, the sealing plate can always keep the movable groove closed until the limiting rod descends to abut against the connecting frame. At this time, the separation mechanism descends to the maximum limit, and at this time, the circular tube is completely immersed in the liquid surface. It can enable the waste liquid above the sedimentation tank to be discharged outward through a separation mesh, a connecting pipe, a U-shaped tube, an L-shaped tube, a circular tube, a movable tube, and a fixed tube, so that the waste liquid without impurities above can be quickly discharged, and thus will not be contaminated and blocked by a large amount of impurities, improving the efficiency of liquid discharge separation.

[0022] 2. By providing a floating ring, a water inlet hole, and a sealing ball, when the inner tube descends inside the hollow slide bar, the inside of the hollow slide bar is in negative pressure at this time, and the one-way valve is opened to allow air to enter. When the limiting rod descends to abut against the connecting frame, the connecting plate, the connecting rod, the cross, and the sealing ball stop descending. As the inner tube continues to descend, the second spring can be compressed. At the same time, the sealing ball disengages from the water inlet hole and releases the seal, enabling the waste liquid to enter the inside of the inner tube through the sealing ball. When the separation mechanism descends onto the impurity layer, the separation mechanism and the inner tube will not continue to descend. At this time, the separation mechanism is in the stratification zone. At this time, since the floating ring continues to descend with the liquid surface, it will drive the connecting frame and the hollow slide bar to continue to descend. At the same time, due to the descent of the connecting frame, the limiting rod can be disengaged from the abutment with the connecting frame. Under the restoring force of the second spring, it drives the limiting rod, the connecting plate, the connecting rod, the cross, and the sealing ball to descend and seal the water inlet hole, so that the waste liquid flowing into the inside of the inner tube can be stored inside the inner tube. At the same time, as the hollow slide bar descends, a high pressure will be generated inside the hollow slide bar, and the piston will be pushed to rise relative to the hollow slide bar, compressing the first spring at the same time, so that power can be stored inside the hollow slide bar to provide power for subsequent cleaning of the separation mesh.

[0023] 3. In the present invention, by providing a piston and a first spring, when the separation net becomes blocked, the hydraulic pressure inside the hollow slide rod will decrease. At this time, the thrust on the movable ball decreases, and at the same time, the third spring releases its elastic force to push the fixed cylinder back to its original position. When the fixed cylinder returns to its original position and abuts against the pressure sensing element, the pressure sensing element will be triggered by the pressure, and at the same time, it is determined that the separation net in this area is blocked, and the water flow rate of the fixed pipe decreases. The control end controls the corresponding second solenoid valve to close, and at the same time, another second solenoid valve is opened to filter through another separation net, ensuring and increasing the flow rate and water pressure of the L-shaped pipe and the fixed pipe. The control end opens the water outlet hole at the blocked position for one to two seconds and then closes it. When the water outlet hole is opened, due to the release of the elastic force of the first spring, the piston will be pushed downward, and part of the stored liquid inside the inner pipe will be flushed from the inner side to the outer side of the separation net through this water outlet hole, washing away the impurities attached to the surface of the separation net and separating the separation net, thereby achieving the effect of cleaning the impurities on the surface of the separation net, so that the separation net is no longer blocked and can be used continuously next time. This design uses the method of alternating the use of two separation nets to improve the separation efficiency of waste liquid discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] As Figures 1 to 13 shown, the present invention provides a waste liquid treatment device applicable to the disassembly and recycling of waste lithium batteries, including a treatment tank 1, a mounting frame 2, a slide bar assembly 3, a floating ring 4, a connecting frame 5, a separation mechanism 6, a water outlet mechanism 7 and a water diversion mechanism 8;

[0040] The mounting frame 2 is installed on the treatment tank 1, the slide bar assembly 3 is slidably installed on the mounting frame 2, the connecting frame 5 is installed at the bottom end of the slide bar assembly 3, the floating ring 4 is connected to the outside of the connecting frame 5, the separation mechanism 6 is arranged at the bottom end of the slide bar assembly 3, the water outlet mechanism 7 is arranged on one side inside the treatment tank 1, and the water diversion mechanism 8 is arranged on the water outlet mechanism 7 and can communicate with the separation mechanism 6;

[0041] The treatment tank 1 includes a settling tank 11, a cavity 12 is opened on one side inside the settling tank 11, and an activity tank 13 that can communicate with the cavity 12 is opened inside the settling tank 11;

[0042] The water outlet mechanism 7 includes a fixed pipe 72 which is installed in the cavity 12 and has one end extending to the outside of the sedimentation tank 11. A movable pipe 71 is sleeved inside the fixed pipe 72. A sealing plate 73 which can move in the movable groove 13 is fixedly sleeved outside the movable pipe 71, and the sealing plate 73 can seal the fixed pipe 72.

[0043] The sliding rod assembly 3 includes a hollow sliding rod 31 which is slidably installed in the mounting frame 2. The bottom end of the hollow sliding rod 31 is connected to the connecting frame 5. An inner pipe 37 is movably sleeved inside the hollow sliding rod 31, and the bottom end of the inner pipe 37 passes through the connecting frame 5 and is connected to a circular plate 38.

[0044] The separation mechanism 6 includes a circular frame 61 which is connected to the circular plate 38. Two separation nets 62 are installed on both sides inside the circular frame 61.

[0045] The water diversion mechanism 8 includes a circular pipe 81 which is fixedly communicated with one end of the movable pipe 71. A sleeve 82 is movably sleeved inside the circular pipe 81, and an L-shaped pipe 83 is movably sleeved inside the sleeve 82. The L-shaped pipe 83 is communicated with a U-shaped pipe 84. Solenoid valves II 85 are arranged at both ends of the U-shaped pipe 84, and the other side of the solenoid valve II 85 is connected to a connecting pipe 86 which can be fixedly communicated with the inside of the separation net 62.

[0046] Adopting the above scheme: the sliding rod assembly 3, the floating ring 4, the connecting frame 5, the separation mechanism 6 and the water diversion mechanism 8 fall onto the liquid surface under their own gravity. At this time, the sliding rod assembly 3 slides down in the mounting frame 2, and under the buoyancy of the floating ring 4, the floating ring 4, the connecting frame 5 and the hollow sliding rod 31 are kept floating on the liquid surface. At this time, the separation mechanism 6 and the water diversion mechanism 8 sink in the waste liquid under their own gravity, so that the inner pipe 37 drives and descends inside the hollow sliding rod 31. At the same time, the water diversion mechanism 8 drives the movable pipe 71 and the sealing plate 73 to descend along the inside of the movable groove 13. During the descending process, the sealing plate 73 can always keep the movable groove 13 closed. Until the limit rod 314 descends to abut against the connecting frame 5, the separation mechanism 6 descends to the maximum extent. At this time, the circular pipe 81 is completely immersed in the liquid surface, and the waste liquid above the sedimentation tank 11 can be discharged outward through a separation net 62, a connecting pipe 86, a U-shaped pipe 84, an L-shaped pipe 83, a circular pipe 81, a movable pipe 71 and a fixed pipe 72, so that the waste liquid without impurities above can be quickly discharged.

[0047] As Figure 6 and Figure 8 shown, an electromagnetic lock I 36 is connected to the top of the mounting frame 2, and a clamping seat I 35 is connected to the outside of the hollow sliding rod 31. The electromagnetic lock I 36 clamps and fixes the clamping seat I 35 through a locking rod.

[0048] Adopt the above solution: The control end controls the locking rod of the electromagnetic lock 1 36 to contract, releasing the fixation of the clamping seat 1 35. At the same time, the fixation of the sliding rod assembly 3, the floating ring 4, the connecting frame 5, the separation mechanism 6, and the water diversion mechanism 8 to the mounting frame 2 is released, so that the sliding rod assembly 3, the floating ring 4, the connecting frame 5, the separation mechanism 6, and the water diversion mechanism 8 can fall onto the liquid surface under their own gravity.

[0049] As Figure 6 and Figure 8 shown, an electromagnetic lock 2 317 is connected to the outside of the hollow sliding rod 31, and a clamping seat 2 316 is connected above the inner tube 37. The electromagnetic lock 2 317 clamps and fixes the clamping seat 2 316 through the locking rod.

[0050] Adopt the above solution: The control end controls the locking rod of the electromagnetic lock 2 317 to contract, releasing the fixation of the clamping seat 2 316. At the same time, the fixation between the inner tube 37 and the hollow sliding rod 31 is released, so that the inner tube 37 can move inside the hollow sliding rod 31.

[0051] As Figure 2 and Figure 5 shown, an electromagnetic lock 3 813 is connected to one side of the circular tube 81, and the locking rod inside the electromagnetic lock 3 813 is clamped inside the sleeve 82 and the L-shaped tube 83.

[0052] Adopt the above solution: As the waste liquid is discharged, the floating ring 4 continuously descends with the liquid surface, and the separation mechanism 6, the water diversion mechanism 8, the fixed tube 72, and the sealing plate 73 continuously descend. When the movable tube 71 abuts against the inner wall of the lower part of the movable groove 13, at this time, the movable tube 71 will descend to the maximum range. At the same time, the control end controls the electromagnetic lock 3 813 to contract the locking rod, releasing and extending the fixation of the circular tube 81, the sleeve 82, and the L-shaped tube 83, and enabling the sliding rod assembly 3, the floating ring 4, the connecting frame 5, and the separation mechanism 6 to continue to descend with the liquid surface. Through the principle of the communicating vessel, even if the circular tube 81 is exposed above the liquid surface, drainage can still continue.

[0053] As Figure 4 、 Figure 12 and Figure 13 shown, both sides of the top end of the inner tube 37 are movably sleeved with limit rods 314. A second spring 315 is sleeved outside the limit rods 314. The two ends of the second spring 315 are respectively connected to the limit rods 314 and the inner tube 37. The top end of the limit rod 314 is connected to a connecting plate 313 above the inner tube 37, and the bottom of the connecting plate 313 is connected to a connecting rod 312 located inside the inner tube 37.

[0054] Adopting the above solution: When the inner tube 37 descends inside the hollow slide bar 31, the inside of the hollow slide bar 31 is in negative pressure at this time, and the one-way valve 34 is opened to allow air intake. When the limiting rod 314 descends to abut against the connecting frame 5, the connecting plate 313, the connecting rod 312, the cross 311, and the sealing ball 310 stop descending. As the inner tube 37 continues to descend, the second spring 315 can be compressed, and at the same time, the sealing ball 310 disengages from the water inlet hole 39 and releases the seal, allowing the waste liquid to enter the inside of the inner tube 37 through the sealing ball 310.

[0055] As Figure 4 and Figure 12 shown, four water inlet holes 39 are circumferentially formed inside the circular plate 38. The bottom end of the connecting rod 312 is connected to a cross 311, and sealing balls 310 capable of sealing the cross 311 are connected to the four ends of the cross 311.

[0056] Adopting the above solution: When the separation mechanism 6 descends onto the impurity layer, the separation mechanism 6 and the inner tube 37 will not continue to descend. At this time, the separation mechanism 6 is in the stratification zone. Since the floating ring 4 continues to descend with the liquid level at this time, it will drive the connecting frame 5 and the hollow slide bar 31 to continue to descend. At the same time, due to the descent of the connecting frame 5, the abutment between the limiting rod 314 and the connecting frame 5 can be released. Under the action of the elastic recovery of the second spring 315, it drives the limiting rod 314, the connecting plate 313, the connecting rod 312, the cross 311, and the sealing ball 310 to descend and seal the water inlet hole 39, so that the waste liquid flowing into the inside of the inner tube 37 can be stored inside the inner tube 37.

[0057] As Figure 3 、 Figure 4 、 Figure 7 and Figure 12 shown, a piston 33 is sleeved inside the hollow slide bar 31. The top of the piston 33 is connected to a first spring 32, and the other end of the first spring 32 is connected to the inner wall of the hollow slide bar 31. One-way valves 34 are provided on both sides of the hollow slide bar 31.

[0058] Adopting the above solution: When the separation mechanism 6 descends onto the impurity layer, as the hollow slide bar 31 descends, a high pressure will be generated inside the hollow slide bar 31, and the piston 33 will be pushed to rise relative to the hollow slide bar 31, while compressing the first spring 32, thereby realizing energy storage inside the hollow slide bar 31.

[0059] As Figure 8 shown, water outlet holes 318 are formed on both sides inside the circular plate 38, and an electromagnetic valve 319 capable of closing the circular plate 38 is provided at the bottom of the circular plate 38.

[0060] Adopt the above solution: The control end controls the corresponding solenoid valve II 85 to close, and at the same time opens another solenoid valve II 85 to filter through another separation net 62, ensuring and increasing the flow rate and water pressure of the L-shaped pipe 83 and the fixed pipe 72. The control end opens the water outlet hole 318 at the blockage for one to two seconds and then closes it. When the water outlet hole 318 is opened, due to the release of the elastic force of the first spring 32, the piston 33 will be pushed downward, and part of the liquid stored inside the inner pipe 37 will flush water from the inner side to the outer side of the separation net 62 through the water outlet hole 318, flushing away the impurities attached to the surface of the separation net 62 and separating from the separation net 62, thereby achieving the effect of cleaning the impurities on the surface of the separation net 62.

[0061] As Figure 5 and Figure 10 shown, a fixed cylinder 87 located below the circular pipe 81 is fixedly connected to the outside of the L-shaped pipe 83. Sliding grooves 88 are opened on both sides inside the fixed cylinder 87. An activity ball 89 that can close the fixed cylinder 87 is movably sleeved inside the sliding grooves 88. The other end of the sliding groove 88 is connected to a net plate 811. A third spring 810 is connected between the activity ball 89 and the net plate 811. A pressure sensing element 812 that can abut against the activity ball 89 is installed on one side inside the sliding groove 88.

[0062] Adopt the above solution: When the separation net 62 is blocked, the hydraulic pressure inside the hollow slide bar 31 will decrease. At this time, the thrust on the activity ball 89 decreases, and at the same time, the third spring 810 releases elastic force to push the fixed cylinder 87 to reset. When the fixed cylinder 87 resets and abuts against the pressure sensing element 812, the pressure sensing element 812 will be triggered by the pressure at this time, and at the same time, it is determined that the separation net 62 is blocked in a certain area, and the water outlet flow rate of the fixed pipe 72 decreases.

[0063] The working principle and usage process of the present invention:

[0064] The waste liquid is introduced into the sedimentation tank 11, and then a flocculant is added for reaction. After the impurities settle, the control terminal controls two solenoid valves II 85 respectively, one is closed and the other is open. During use, only one separation net 62 can be used, and the other separation net 62 is in a standby state. The locking rods of the electromagnetic lock I 36 and the electromagnetic lock II 317 are contracted to release the fixation of the clamping seat I 35 and the clamping seat II 316. At the same time, the fixation of the sliding rod assembly 3, the floating ring 4, the connecting frame 5, the separation mechanism 6 and the water diversion mechanism 8 with the mounting frame 2 is released, so that they fall to the liquid surface under their own gravity. At this time, the sliding rod assembly 3 slides down on the mounting frame 2 and, under the buoyancy of the floating ring 4, keeps the floating ring 4, the connecting frame 5 and the hollow sliding rod 31 floating on the liquid surface. At this time, the separation mechanism 6 and the water diversion mechanism 8 sink in the waste liquid under their own gravity, so that the inner tube 37 drives and descends inside the hollow sliding rod 31. At the same time, the water diversion mechanism 8 drives the movable tube 71 and the sealing plate 73 to descend along the inside of the movable groove 13, and the sealing plate 73 can always keep the movable groove 13 closed during the descent. Until the limiting rod 314 descends to abut against the connecting frame 5, the separation mechanism 6 descends to the maximum limit. At this time, the circular tube 81 is completely immersed in the liquid surface, and the waste liquid above the sedimentation tank 11 can be discharged outward through a separation net 62, a connecting pipe 86, a U-shaped pipe 84, an L-shaped pipe 83, a circular tube 81, a movable tube 71 and a fixed tube 72, so that the waste liquid without impurities above can be quickly discharged.

[0065] When water flows through the L-shaped pipe 83, since the separation net 62 is not blocked, the pressure generated by the flow inside the L-shaped pipe 83 is the largest, which will push the movable ball 89 to move outward and compress the spring III 810. At this time, the pressure sensing element 812 is no longer under pressure.

[0066] As the waste liquid is discharged, the floating ring 4 continuously descends with the liquid surface, and the separation mechanism 6, the water diversion mechanism 8, the fixed tube 72 and the sealing plate 73 continuously descend. When the movable tube 71 abuts against the inner wall of the lower part of the movable groove 13, at this time, the movable tube 71 will descend to the maximum range. At the same time, the control terminal controls the electromagnetic lock III 813 to contract the locking rod, releases the fixation of the circular tube 81, the sleeve 82 and the L-shaped pipe 83 and extends them, so that the sliding rod assembly 3, the floating ring 4, the connecting frame 5 and the separation mechanism 6 can continue to descend with the liquid surface. Through the principle of the communicating vessel, even if the circular tube 81 is exposed above the liquid surface, drainage can still continue.

[0067] When the inner tube 37 descends inside the hollow slide rod 31, the inside of the hollow slide rod 31 is in negative pressure at this time, and the one-way valve 34 is opened to let air in. When the limit rod 314 descends to abut against the connecting frame 5, the connecting plate 313, the connecting rod 312, the cross 311 and the sealing ball 310 stop descending. As the inner tube 37 continues to descend, the second spring 315 can be compressed. At the same time, the sealing ball 310 disengages from the water inlet hole 39 and releases the seal, allowing the waste liquid to enter the inside of the inner tube 37 through the sealing ball 310. When the separation mechanism 6 descends onto the impurity layer, the separation mechanism 6 and the inner tube 37 will not continue to descend. At this time, the separation mechanism 6 is in the stratification zone. At this time, as the floating ring 4 continues to descend with the liquid level, it will drive the connecting frame 5 and the hollow slide rod 31 to continue descending. At the same time, due to the descent of the connecting frame 5, the abutment between the limit rod 314 and the connecting frame 5 can be released. Under the action of the elastic force recovery of the second spring 315, it drives the limit rod 314, the connecting plate 313, the connecting rod 312, the cross 311 and the sealing ball 310 to descend and seal the water inlet hole 39, so that the waste liquid flowing into the inside of the inner tube 37 can be stored inside the inner tube 37. At the same time, as the hollow slide rod 31 descends, a high pressure will be generated inside the hollow slide rod 31, and the piston 33 will be pushed to rise relative to the hollow slide rod 31, while compressing the first spring 32, thereby achieving energy storage inside the hollow slide rod 31.

[0068] When the separation net 62 is blocked, the hydraulic pressure inside the hollow slide rod 31 will drop. At this time, the thrust on the movable ball 89 drops, and at the same time, the third spring 810 releases its elastic force to push the fixed cylinder 87 to reset. When the fixed cylinder 87 resets and abuts against the pressure sensing element 812, the pressure sensing element 812 will be triggered by the pressure at this time, and it is determined that the separation net 62 is blocked in this area. The water flow rate of the fixed pipe 72 drops, and the control end controls the corresponding second solenoid valve 85 to close, and at the same time opens another second solenoid valve 85 to filter through another separation net 62, ensuring and increasing the flow rate and water pressure of the L-shaped pipe 83 and the fixed pipe 72. The control end opens the water outlet hole 318 at the blocked place for one to two seconds and then closes it. When the water outlet hole 318 is opened, due to the release of the elastic force of the first spring 32, the piston 33 will be pushed to move downward, and part of the stored liquid inside the inner tube 37 will flush water from the inner side to the outer side of the separation net 62 through the water outlet hole 318, washing away the impurities attached to the surface of the separation net 62 and detaching from the separation net 62, thereby achieving the effect of cleaning the impurities on the surface of the separation net 62 and making the separation net 62 no longer blocked for continued use next time.
