Description

Technical Field

[0001] The invention belongs to the technical field of waste lithium battery treatment, and in particular is a waste liquid treatment device suitable for disassembling and recycling waste lithium batteries. Background Art

[0002] After the used lithium batteries are disassembled and discharged, waste liquid will be generated. The waste liquid is purified by waste liquid treatment equipment. The existing waste liquid pretreatment is to add flocculants to the waste liquid to agglomerate the fine impurities in the waste liquid, and then separate the impurities in the waste liquid after they are settled. The existing separation method is usually to directly lower the 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 be always in the stratification area of ​​​​the waste liquid and impurities, resulting in some floating impurities in the stratification often contaminating and adhering to the filter screen at the pumping end during the pumping process, thereby causing the filter screen to become blocked, and then resulting in a decrease in pumping efficiency. The operator is often required to repeatedly clean the filter screen, which reduces the work efficiency of the separation operation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention arranges an inner tube, a separation net and a movable tube, so that the slide bar assembly, the float ring, the connecting frame, the separation mechanism and the water diversion mechanism fall to the liquid surface under the action of their own gravity. At this time, the slide bar assembly slides up and down on the mounting frame, and under the buoyancy of the float ring, the float ring, the connecting frame and the hollow slide bar are kept floating on the liquid surface. At this time, the separation mechanism and the water diversion mechanism sink in the waste liquid under the action of their own gravity, so that the inner tube drives the interior of the hollow slide bar to descend, and at the same time, the water diversion mechanism drives the movable tube and the sealing plate to descend along the interior of the movable groove. During the descent process, the sealing plate can always keep the closure of the movable groove to the movable groove until the limit rod is lowered to abut against the connecting frame, and the separation mechanism is lowered to the maximum limit. At this time, the round tube is completely immersed in the liquid surface, so that the waste liquid above the sedimentation tank can be discharged outward through a separation net, a connecting pipe, a U-shaped pipe, an L-shaped pipe, a round pipe, a movable pipe and a fixed pipe, so that the waste liquid above without impurities can be quickly discharged, and thus will not be contaminated and blocked by a large amount of impurities, thereby improving the efficiency of liquid discharge separation.

[0015] 2. The present invention provides a floating ring, a water inlet hole and a sealing ball. When the inner tube descends inside the hollow slide rod, the interior of the hollow slide rod is in negative pressure and the one-way valve is opened to allow air to enter. When the limit 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 spring 2 can be compressed. At the same time, the sealing ball is separated from the water inlet hole and released from the seal, so that the waste liquid can enter the interior of the inner tube through the sealing ball. When the separation mechanism descends to the impurity layer, the separation mechanism and the inner tube will not continue to descend. At this time, the separation mechanism is in the stratified area. At this time, since the floating ring is lowered with the water inlet hole, the separation mechanism and the inner tube will not continue to descend. The continued drop of the liquid level will drive the connecting frame and the hollow sliding rod to continue to drop. At the same time, due to the drop of the connecting frame, the limit rod can be released from the abutment with the connecting frame. Under the elastic recovery action of spring two, the limit rod, connecting plate, connecting rod, cross and sealing ball are driven to drop and seal the water inlet hole, so that the waste liquid flowing into the inner tube can be stored inside the inner tube. At the same time, as the hollow sliding rod drops, high pressure will be generated inside the hollow sliding rod, and the piston will be pushed up relative to the hollow sliding rod, and spring one will be compressed at the same time, so that force can be stored inside the hollow sliding rod to provide power for subsequent cleaning of the separation net.

[0016] 3. The present invention sets a piston and a spring 1. When the separation net is blocked, the hydraulic pressure inside the hollow slide rod will decrease. At this time, the thrust on the movable ball decreases, and the spring 3 releases the elastic force to push the fixed cylinder to reset. When the fixed cylinder is reset and abuts against the pressure sensing element, the pressure sensing element will be triggered by the pressure, and it is determined that the separation net is blocked in an area. The water flow rate of the fixed pipe decreases, and the control end controls the corresponding solenoid valve 2 to close, and opens another solenoid valve 2 at the same time, filtering through another separation net to ensure and improve 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 spring 1, the piston will be pushed downward, and part of the liquid stored in the inner tube will be flushed from the inside to the outside of the separation net through the water outlet hole, and the impurities attached to the surface of the separation net will be flushed away and the separation net will be detached, thereby achieving the effect of cleaning the impurities on the surface of the separation net, so that the separation net is no longer blocked so that it can be used next time. The design adopts the method of alternating the two separation nets to improve the discharge and separation efficiency of the waste liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figures 1 to 13 As shown, the present invention provides a waste liquid treatment device suitable for disassembling and recycling waste lithium batteries, including a treatment pool 1, a mounting frame 2, a slide rod assembly 3, a float 4, a connecting frame 5, a separation mechanism 6, a water outlet mechanism 7 and a water diversion mechanism 8; The mounting frame 2 is mounted on the treatment pool 1, the slide bar assembly 3 is slidably mounted on the mounting frame 2, the connecting frame 5 is mounted on the bottom end of the slide bar assembly 3, the float 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 of the treatment pool 1, and the water diversion mechanism 8 is arranged on the water outlet mechanism 7 and can be communicated with the separation mechanism 6; The treatment tank 1 includes a sedimentation tank 11, a cavity 12 is opened on one side of the sedimentation tank 11, and a movable groove 13 that can communicate with the cavity 12 is opened inside the sedimentation tank 11; The water outlet mechanism 7 includes a fixed pipe 72, which is installed in the cavity 12 and one end of which extends to the outside of the sedimentation tank 11. The fixed pipe 72 is sleeved with a movable pipe 71, and the outer portion of the movable pipe 71 is fixedly sleeved with a sealing plate 73 that can move in the movable groove 13, and the sealing plate 73 can seal the fixed pipe 72; The slide bar assembly 3 includes a hollow slide bar 31, which is slidably mounted in the mounting frame 2, and the bottom end of the hollow slide bar 31 is connected to the connecting frame 5. The inner sleeve of the hollow slide bar 31 is provided with an inner tube 37, and the bottom end of the inner tube 37 passes through the connecting frame 5 and is connected to a circular plate 38. The separation mechanism 6 includes a round frame 61, which is connected to the round plate 38. Separation nets 62 are installed on both sides of the inside of the round frame 61, and two separation nets 62 are provided; The water diversion mechanism 8 includes a circular tube 81, which is fixedly connected to one end of the movable tube 71. A sleeve 82 is movably sleeved in the circular tube 81, and an L-shaped tube 83 is movably sleeved in the sleeve 82. The L-shaped tube 83 is connected to a U-shaped tube 84. Both ends of the U-shaped tube 84 are provided with solenoid valves 85. The other side of the solenoid valve 85 is connected to a connecting tube 86 that can be fixedly connected to the separation net 62.

[0021] The above scheme is adopted: the slide bar assembly 3, the float 4, the connecting frame 5, the separation mechanism 6 and the water diversion mechanism 8 are made to fall to the liquid surface under the action of their own gravity. At this time, the slide bar assembly 3 slides up and down on the mounting frame 2, and under the buoyancy of the float 4, the float 4, the connecting frame 5 and the hollow slide bar 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 the action of their own gravity, so that the inner tube 37 drives the inside of the hollow slide bar 31 to descend, and at the same time, the water diversion mechanism 8 drives the movable tube 71 and the sealing plate 7 3 descends along the inside of the movable groove 13, and the sealing plate 73 can always keep the movable groove 13 closed during the descending process, until the limit rod 314 descends to abut against the connecting frame 5, and the separation mechanism 6 descends to the maximum limit. At this time, the round pipe 81 is completely immersed in the liquid surface, and the waste liquid above the sedimentation tank 11 can be discharged to the outside through a separation net 62, a connecting pipe 86, a U-shaped pipe 84, an L-shaped pipe 83, a round pipe 81, a movable pipe 71 and a fixed pipe 72, so that the waste liquid above without impurities can be quickly discharged.

[0022] like Figure 6 and Figure 8 As shown, the top of the mounting frame 2 is connected with an electromagnetic lock 36, and the outer side of the hollow slide bar 31 is connected with a clamping seat 35, and the electromagnetic lock 36 clamps the clamping seat 35 through a locking rod.

[0023] The above scheme is adopted: the control end controls the lock rod of the electromagnetic lock 36 to retract, releases the fixation of the holder 35, and simultaneously releases the fixation of the slide bar assembly 3, the float 4, the connecting frame 5, the separation mechanism 6 and the water diversion mechanism 8 from the mounting frame 2, so that the slide bar assembly 3, the float 4, the connecting frame 5, the separation mechanism 6 and the water diversion mechanism 8 can fall to the liquid surface under the action of their own gravity.

[0024] like Figure 6 and Figure 8As shown, the outside of the hollow slide rod 31 is connected to an electromagnetic lock 2 317 , and the upper part of the inner tube 37 is connected to a clamping seat 2 316 , and the electromagnetic lock 2 317 clamps the clamping seat 2 316 through a locking rod.

[0025] By adopting the above solution, the control end controls the lock rod of the second electromagnetic lock 317 to retract, releases the fixation of the second holder 316, and simultaneously releases the fixation between the inner tube 37 and the hollow slide bar 31, so that the inner tube 37 can move inside the hollow slide bar 31.

[0026] like Figure 2 and Figure 5 As shown, one side of the circular tube 81 is connected to an electromagnetic lock 3 813 , and a locking rod inside the electromagnetic lock 3 813 is clamped in the inside of the sleeve 82 and the L-shaped tube 83 .

[0027] With the above solution, as the waste liquid is discharged, the float 4 continues to drop along with the liquid level, and the separation mechanism 6, the water diversion mechanism 8, the fixed pipe 72 and the sealing plate 73 continue to drop. When the movable pipe 71 abuts against the inner wall below the movable groove 13, the movable pipe 71 will drop to the maximum range. At the same time, the control end controls the electromagnetic lock 3 813 to retract the lock rod, release the fixation of the circular pipe 81, the sleeve 82 and the L-shaped pipe 83 and extend them, and allow the slide bar assembly 3, the float 4, the connecting frame 5 and the separation mechanism 6 to continue to drop. Through the principle of the communicating vessel, even if the circular pipe 81 is exposed to the liquid surface, it can still continue to drain.

[0028] like Figure 4 , Fig.12 and Fig.13 As shown, both sides of the top end of the inner tube 37 are movably sleeved with a limit rod 314, the outer portion of the limit rod 314 is sleeved with a spring 2 315, the two ends of the spring 2 315 are respectively connected to the limit rod 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.

[0029] The above scheme is adopted: when the inner tube 37 descends inside the hollow slide rod 31, the interior of the hollow slide rod 31 is in negative pressure, and the one-way valve 34 is opened to let in air. 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 spring 2 315 can be compressed, and the sealing ball 310 is detached from the water inlet hole 39 and released, so that the waste liquid can enter the interior of the inner tube 37 through the sealing ball 310.

[0030] like Figure 4 and Fig.12As shown, four water inlet holes 39 are formed around the inside of the circular plate 38 , a cross 311 is connected to the bottom end of the connecting rod 312 , and sealing balls 310 that can seal the cross 311 are connected to the four ends of the cross 311 .

[0031] With the above solution, when the separation mechanism 6 descends to 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 sliding rod 31 to continue to descend. At the same time, due to the descent of the connecting frame 5, the limit rod 314 can be released from the abutment with the connecting frame 5. Under the elastic recovery action of the second spring 315, the limit rod 314, the connecting plate 313, the connecting rod 312, the cross 311 and the sealing ball 310 are driven to descend and the water inlet hole 39 is sealed, so that the waste liquid flowing into the inner tube 37 can be stored in the inner tube 37.

[0032] like Figure 3 , Figure 4 , Figure 7 and Fig.12 As shown, a piston 33 is sleeved in the hollow slide rod 31, a spring 32 is connected to the top of the piston 33, the other end of the spring 32 is connected to the inner wall of the hollow slide rod 31, and one-way valves 34 are provided on both sides of the hollow slide rod 31.

[0033] Adopting the above scheme: when the separation mechanism 6 descends to the impurity layer, as the hollow slide rod 31 descends, high pressure will be generated inside the hollow slide rod 31, and the piston 33 will be pushed up relative to the hollow slide rod 31, while compressing the spring 1 32, so that force can be stored inside the hollow slide rod 31.

[0034] like Figure 8 As shown, water outlet holes 318 are provided on both sides of the circular plate 38, and a solenoid valve 319 is provided at the bottom of the circular plate 38 to close the circular plate 38.

[0035] The above scheme is adopted: the control end controls the corresponding solenoid valve 2 85 to close, and opens another solenoid valve 2 85 at the same time, filtering is performed through another separation net 62, so as to ensure and improve the flow and water pressure of the L-shaped tube 83 and the fixed tube 72, and the control end opens the water outlet 318 at the blocked position for one to two seconds and then closes it. When the water outlet 318 is opened, due to the release of the elastic force of the spring 1 32, the piston 33 will be pushed to move downward, and part of the liquid stored in the inner tube 37 will be flushed from the inside to the outside of the separation net 62 through the water outlet 318, so as to flush away the impurities attached to the surface of the separation net 62 and detach the separation net 62, thereby achieving the effect of cleaning the impurities on the surface of the separation net 62.

[0036] like Figure 5 and Fig.10As shown, the outside of the L-shaped tube 83 is fixedly connected to a fixed cylinder 87 located below the circular tube 81, and slide grooves 88 are provided on both sides of the inside of the fixed cylinder 87. The internal movable sleeve of the slide groove 88 is provided with a movable ball 89 that can close the fixed cylinder 87. The other end of the slide groove 88 is connected to a mesh plate 811, and a spring 810 is connected between the movable ball 89 and the mesh plate 811. A pressure sensing element 812 that can abut against the movable ball 89 is installed on one side of the inside of the slide groove 88.

[0037] Adopting the above scheme: when the separation net 62 is blocked, the hydraulic pressure inside the hollow slide rod 31 will decrease, and the thrust on the movable ball 89 will decrease. At the same time, the spring three 810 releases the elastic force to push the fixed cylinder 87 to reset. When the fixed cylinder 87 is reset and abuts against the pressure sensing element 812, the pressure sensing element 812 will be triggered by the pressure, and it is determined that the separation net 62 is blocked in an area, and the water outlet flow of the fixed pipe 72 decreases.

[0038] The working principle and use process of the present invention: The waste liquid is passed into the sedimentation tank 11, and then the flocculant is added for reaction. After the impurities are settled, the control end controls the two electromagnetic valves 85, one is closed and the other is open. When in use, only one separation net 62 can be used, and the other separation net 62 is in a standby state. The lock rods of the electromagnetic lock 1 36 and the electromagnetic lock 2 317 are controlled to retract, and the fixation of the card seat 1 35 and the card seat 2 316 is released. At the same time, the fixation of the slide rod assembly 3, the float 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 the action of their own gravity. At this time, the slide rod assembly 3 slides up and down on the mounting frame 2, and under the buoyancy of the float ring 4, the float ring 4, the connecting frame 5 and the hollow slide 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 the action of their own gravity, so that the inner tube 37 drives the interior of the hollow slide rod 31 to descend, and at the same time, the water diversion mechanism 8 drives the movable tube 71 and the sealing plate 73 to descend along the interior 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 is lowered to abut against the connecting frame 5, and the separation mechanism 6 is lowered to the maximum limit. At this time, the circular tube 81 is completely immersed in the liquid surface, so that the waste liquid above the sedimentation tank 11 can be discharged outward through a separation net 62, a connecting tube 86, a U-shaped tube 84, an L-shaped tube 83, a circular tube 81, a movable tube 71 and a fixed tube 72, so that the waste liquid above that does not contain impurities can be quickly discharged.

[0039] When water flows through the L-shaped tube 83, since the separation net 62 is not blocked, the pressure generated by the flow inside the L-shaped tube 83 is the largest, which will push the movable ball 89 to move outward and compress the spring three 810. At this time, the pressure sensor element 812 is no longer under pressure.

[0040] As the waste liquid is discharged, the float 4 continues to drop with the liquid level, and the separation mechanism 6, the water diversion mechanism 8, the fixed pipe 72 and the sealing plate 73 continue to drop. When the movable pipe 71 abuts against the inner wall below the movable groove 13, the movable pipe 71 will drop to the maximum range. At the same time, the control end controls the electromagnetic lock 3 813 to retract the lock rod, release the fixation of the circular pipe 81, the sleeve 82 and the L-shaped pipe 83 and extend them, and allow the slide bar assembly 3, the float 4, the connecting frame 5 and the separation mechanism 6 to continue to drop. Through the principle of the communicating vessel, even if the circular pipe 81 is exposed to the liquid surface, it can still continue to drain.

[0041] When the inner tube 37 descends inside the hollow slide rod 31, the interior of the hollow slide rod 31 is in negative pressure, and the one-way valve 34 is opened to allow air to enter. 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 spring 2 315 can be compressed, and the sealing ball 310 is separated from the water inlet hole 39 and released, so that the waste liquid can enter the interior of the inner tube 37 through the sealing ball 310. When the separation mechanism 6 descends to 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 area. At this time, since the floating ring 4 moves with the liquid surface The continued descent will drive the connecting frame 5 and the hollow slide rod 31 to continue to descend. At the same time, due to the descent of the connecting frame 5, the limiting rod 314 can be released from the abutment with the connecting frame 5. Under the elastic recovery action of the spring 2 315, the limiting rod 314, the connecting plate 313, the connecting rod 312, the cross 311 and the sealing ball 310 are driven to descend and the water inlet hole 39 is sealed, so that the waste liquid flowing into the inner tube 37 can be stored in the inner tube 37. At the same time, as the hollow slide rod 31 descends, 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, and the spring 1 32 will be compressed at the same time, so that force storage can be achieved inside the hollow slide rod 31.

[0042] When the separation net 62 is clogged, the hydraulic pressure inside the hollow slide rod 31 will decrease, and the thrust on the movable ball 89 will decrease. At the same time, the spring three 810 releases its elastic force to push the fixed cylinder 87 to reset. When the fixed cylinder 87 resets and abuts against the pressure sensor element 812, the pressure sensor element 812 will be triggered by the pressure, and it is determined that the separation net 62 is blocked in an area. The water flow rate of the fixed pipe 72 decreases, and the control end controls the corresponding solenoid valve two 85 to close, and opens another solenoid valve two 85 to filter through another separation net 62 to ensure And increase the flow and water pressure of the L-shaped tube 83 and the fixed tube 72, control the end to open the water outlet 318 at the blocked position for one to two seconds and then close it. When the water outlet 318 is opened, the elastic force of the spring 32 is released, which will push the piston 33 to move downward, and flush part of the liquid inside the inner tube 37 from the inside to the outside of the separation net 62 through the water outlet 318, flushing away the impurities attached to the surface of the separation net 62 and detaching the separation net 62, thereby achieving the effect of cleaning the impurities on the surface of the separation net 62, so that the separation net 62 is no longer blocked and can be used next time.
