Description

Technical Field

[0001] The invention belongs to the technical field of rotary kilns, in particular to a rotary kiln for processing lithium batteries. Background Art

[0002] The rotary kiln is a commonly used device in the preparation and processing of battery materials. When processing battery materials, the rotary kiln usually produces high-temperature acidic waste gas containing sulfur dioxide, carbon dioxide and hydrogen chloride. The waste gas will be discharged upward through the smoke exhaust mechanism, but there is a temperature difference between the temperature inside the smoke exhaust mechanism and the temperature inside the rotary kiln, which causes a large amount of acidic condensed water to be produced when the waste gas contacts the pipe wall of the smoke exhaust mechanism. These condensed waters accumulate in the smoke exhaust mechanism for a long time and will corrode the pipe wall of the smoke exhaust mechanism, thereby causing the risk of waste gas leakage from the pipe wall.

[0003] At present, the commonly used solution is to use ceramic lining on the pipe wall to improve the corrosion resistance of the smoke exhaust mechanism. However, the exhaust gas contains a large amount of waste particles. These particles will collide with the ceramic lining in large quantities at the bend of the smoke exhaust mechanism, causing the ceramic lining to be damaged for a long time. At this time, the damaged part of the ceramic lining will be brittle. Under the action of thermal expansion of the ceramic lining, the damaged part of the ceramic lining will easily crack, and then the acidic condensed water inside the ceramic lining will corrode the pipe wall again.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides a water outlet and a water inlet interface, so that the waste gas generated inside the rotary kiln will enter the interior of the ceramic lining. At this time, the water inside the water tank 1 can flow down along the inner wall of the ceramic lining through the water outlet under the action of gravity, and pass through the bend of the ceramic lining on the way, thereby quickly taking away the acidic condensed water accumulated at the bend of the ceramic lining, and at the same time can dilute the acidic condensed water, and the diluted acid water will flow along the pipe wall of the ceramic lining into the interior of the water inlet interface, and enter the water tank 2 through the water inlet interface, thereby forming a continuous flow of water on the inner wall of the ceramic lining. The continuous flow of water can contact the flow of water before the waste particles touch the inner wall of the ceramic lining, thereby having a buffering effect on the impact of the waste particles, and thus can greatly reduce the damage to the ceramic lining, and at the same time can prevent the acidic condensed water from accumulating on the pipe wall of the ceramic lining for a long time, thereby extending the service life of the ceramic lining, avoiding the expansion and cracking of the ceramic lining, and greatly reducing the risk of waste gas leakage after the pipeline is corroded.

[0022] 2. The present invention provides a filter plate and slaked lime. When weakly acidic water enters the interior of the water tank 2, it will be guided to the water receiving box through the guide block, so that the gravity of the water receiving box increases. When the gravity of the water receiving box is greater than the elastic force of the first elastic member, the clamping rod will be squeezed by the water receiving box and will shrink into the fixed block 2 and detach from the water receiving box, so that the water receiving box flips over. During the flipping of the water receiving box, the weakly acidic water in the water receiving box will be poured onto the filter plate to filter out the waste particles in the acid water, and then the acid water flows to the net The inside of the box is in contact with slaked lime, and the acid water is neutralized during a brief contact, and then flows down to the bottom of the inside of the second grey water tank. Since the acidic condensed water is weakly acidic after dilution with the water source, the weakly acidic water here can be neutralized into a weaker acid or neutral or weakly alkaline after a brief contact with slaked lime. In the process of water circulation, it can be ensured that the water will not be strongly acidic or strongly alkaline, avoiding strong acidic or strongly alkaline water from corroding the ceramic lining and pipes, further protecting the smoke exhaust mechanism and ensuring the service life of the smoke exhaust mechanism.

[0023] 3. The present invention sets a piston and a through hole. When the water receiving box is flipped, the rotating arm and the through hole will rotate at the same time, and pull the piston to move upward inside the movable cylinder. At this time, the gas inside the movable cylinder will be discharged slowly through the through hole, so as to play the effect of piston rising damping. At this time, the second elastic member is stretched, and at the same time plays the effect of water receiving box flipping damping, so that the flipping speed of the water receiving box is reduced. Since the flipping speed of the water receiving box is reduced, the movable water storage component can pour water relatively evenly every time it flips one degree, so that each screen surface of the filter plate can be reasonably used, and at the same time, the slaked lime spread in the mesh box can be relatively evenly in contact with water, avoiding the slaked lime on the right side and the right side of the filter plate from being over-used after the water receiving box is quickly flipped.

[0024] 4. The present invention sets an electromagnetic plate 1 and a closing plate. When the water receiving box is flipped, the water receiving box will no longer abut against the abutment plate. At this time, the pressure sensing element will no longer be subjected to pressure. At this time, the control end will close the electromagnetic plate 1. Due to the closure of the electromagnetic plate 1, the electromagnetic plate 1 loses its magnetic attraction to the magnetic part 1. At this time, the second elastic part 1 is in tension. Due to the recovery effect of the elastic force, the closing plate will be driven to rise rapidly and the water outlet end of the guide block will be closed, thereby blocking the water flow inside the water tank 2 from continuing to be discharged. During the flipping process of the water receiving box, the guide block is prevented from continuing to fall into the water, and at the same time, the exhaust gas inside the ceramic lining is prevented from accidentally leaking into the water tank 2 through the guide block, resulting in the risk of exhaust gas leaking from the heat dissipation holes.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 10 As shown, the present invention provides a rotary kiln for lithium battery processing, comprising a base 1, a rotary kiln 2, a smoke exhaust mechanism 3, a buffer mechanism 4, and a water storage mechanism 5;

[0038] The rotary kiln 2 is arranged on one side of the base 1, the water storage mechanism 5 is arranged on the other side of the base 1, the smoke exhaust mechanism 3 is arranged on the water storage mechanism 5 and communicated with the rotary kiln 2, and the buffer mechanism 4 is arranged on the smoke exhaust mechanism 3 and communicated with the water storage mechanism 5;

[0039] The smoke exhaust mechanism 3 includes a pipe 33, which is movably connected to one side of the rotary kiln 2. A heat-conducting member 32 is sleeved inside the pipe 33, and a ceramic lining 31 is sleeved inside the heat-conducting member 32. One end of the heat-conducting member 32 extends into the rotary kiln 2 and is connected to a heat-conducting ring 34 that can contact the inner wall of the rotary kiln 2. The pipe 33 is installed on the water storage mechanism 5.

[0040] The buffer mechanism 4 includes a water tank 41, which is installed on the pipe 33. A water outlet 42 installed above the inner bend of the ceramic liner 31 is fixedly connected to the lower part of one side of the water tank 41. A row of heat-conducting strips 43 are connected to one side of the outer side of the heat-conducting member 32, and the other ends of the row of heat-conducting strips 43 extend to the inside of the water tank 41.

[0041] The water storage mechanism 5 includes a water tank 51, which is installed on the base 1 and connected to the pipeline 33. The upper part of one side of the water tank 51 is fixedly connected to a water inlet interface 52 installed below the inner bend of the ceramic lining 31.

[0042] By adopting the above scheme, the exhaust gas generated inside the rotary kiln 2 will enter the interior of the ceramic lining 31. At this time, the water inside the water tank 1 41 can flow down along the inner wall of the ceramic lining 31 through the water outlet 42 under the action of gravity, and pass through the bend of the ceramic lining 31 on the way, thereby quickly taking away the acidic condensed water accumulated at the bend of the ceramic lining 31, and at the same time, it can dilute the acidic condensed water, and the diluted acid water will flow along the pipe wall of the ceramic lining 31 into the inside of the water inlet interface 52, and enter the water tank 2 51 through the water inlet interface 52, so that a continuous flow of water can be formed on the inner wall of the ceramic lining 31. The continuous flow of water can contact the flow of water before the waste particles touch the inner wall of the ceramic lining 31, so as to have a buffering effect on the impact of the waste particles, thereby greatly reducing the damage to the ceramic lining 31, and preventing the acidic condensed water from accumulating on the pipe wall of the ceramic lining 31 for a long time.

[0043] like Figure 1 and Figure 2 As shown, a guide block 53 which can communicate with the water inlet interface 52 is fixedly installed on the upper part of the interior of the second water tank 51, a closing assembly 54 is installed below the guide block 53, a sealing plate 55 located on the right side of the guide block 53 is installed on the upper part of the interior of the second water tank 51, a movable water storage assembly 56 is arranged in the second water tank 51, and a fixing mechanism 57 is arranged on the back of the second water tank 51.

[0044] With the above solution, the flowing water falls into the movable water storage assembly 56 through the guide block 53, increasing the weight of the movable water storage assembly 56, so that the gravity of the movable water storage assembly 56 increases, triggering the fixing mechanism 57 to release the fixing of the movable water storage assembly 56, and at the same time, the fixing mechanism 57 operates to close the guide block 53, and then the movable water storage assembly 56 operates, so that the flowing water pours out from the movable water storage assembly 56 downward. 1 and 2

[0045] like Figures 2 to 6 As shown, the movable water storage assembly 56 includes a water receiving box 561, which is movably installed in the water tank 51, and the upper part of one side of the water receiving box 561 is abutted against the abutment plate 543. A rotating arm 563 coaxial with the water receiving box 561 is movably installed on the back of the water tank 51, and a movable cylinder 565 is movably installed on the lower part of the back of the water tank 51. A piston 566 is sleeved inside the movable cylinder 565, one end of the piston 566 extends to the outside of the movable cylinder 565 and can be hinged to the rotating arm 563, the other end of the piston 566 is connected to the second elastic member 567, and the other end of the second elastic member 567 is connected to the movable cylinder 565. Four one-way valves 562 arranged around the top of the movable cylinder 565 are provided, and a through hole 564 is opened on the one-way valve 562.

[0046] The above scheme is adopted: when the water receiving box 561 is flipped, the rotating arm 563 and the through hole 564 will rotate at the same time, and pull the piston 566 to move upward inside the movable cylinder 565. At this time, the gas inside the movable cylinder 565 will be discharged slowly through the through hole 564, thereby playing the role of damping the rise of the piston 566. At this time, the second elastic member 567 is stretched, and at the same time plays the role of damping the flipping of the water receiving box 561, so that the flipping speed of the water receiving box 561 is reduced. Since the flipping speed of the water receiving box 561 is reduced, the movable water storage assembly 56 can pour water relatively evenly every time it flips one degree, so that each screen surface of the filter plate 64 can be reasonably used, and at the same time, the slaked lime 63 spread in the mesh box 62 can be relatively evenly in contact with water.

[0047] like Figure 8 As shown, the clamping mechanism 57 includes a second fixed block 571, which is installed on the back of the second water tank 51. The internal movable sleeve of the second fixed block 571 is connected with a movable block 572. One side of the movable block 572 is connected with a clamping rod 573. The other end of the clamping rod 573 is hemispherical and passes through the second water tank 51 and is clamped in the inside of the water receiving box 561.

[0048] The above scheme is adopted: when the weakly acidic flowing water enters the interior of the water tank 51, it will be guided to the water receiving box 561 through the guide block 53, so that the gravity of the water receiving box 561 increases. When the gravity of the water receiving box 561 is greater than the elastic force of the first elastic member 575, the clamping rod 573 will be squeezed by the water receiving box 561 and will shrink into the fixed block 571 and detach from the water receiving box 561, causing the water receiving box 561 to flip over, so that the water volume of the water receiving box 561 when it flips over can be determined.

[0049] like Figure 8 As shown, the other side of the movable block 572 is connected to a magnetic piece 576, and the movable block 572 is connected to moving rods 574 located on both sides of the magnetic piece 576, and the other end of the moving rod 574 extends to the outside of the fixed block 571, and the outside of the movable rod 574 is sleeved with a first elastic piece 575, one end of the first elastic piece 575 is connected to the movable block 572, and the other end of the first elastic piece 575 is connected to the fixed block 571, and the interior of the fixed block 571 is installed with an electromagnetic plate 577 facing the magnetic piece 576.

[0050] Optionally, the magnetic member is a magnet or the like.

[0051] The above solution is adopted: when the water receiving box 561 is flipped over, the water receiving box 561 will no longer abut against the abutment plate 543, and the pressure sensing element 542 will no longer be subjected to pressure. At this time, the control end will turn on the electromagnetic plate 2 577, so that the electromagnetic plate 2 577 can generate suction on the magnetic part 2 576, thereby adsorbing the magnetic part 2 576 onto the electromagnetic plate 2 577, and at the same time, the retracted clamping rod 573 and the movable block 572 are fixed to prevent the clamping rod 573 from popping out before the water receiving box 561 is reset.

[0052] like Figure 3 and Figure 7 As shown, the closing component 54 includes a fixed block 541, which is installed under the guide block 53. A pressure sensing element 542 is installed below the fixed block 541, and a stop plate 543 is connected below the pressure sensing element 542. A closing plate 544 is provided in the internal movable sleeve of the fixed block 541. Sliders 545 that can slide inside the fixed block 541 are connected below both sides of the closing plate 544. The top of the slide 545 is connected to a second elastic member 546, and the other end of the second elastic member 546 is connected to the fixed block 541.

[0053] The above scheme is adopted: when the magnetic member 548 loses its restraint, the second elastic member 546 is stretched. Due to the recovery effect of the elastic force, the closing plate 544 will be driven to rise rapidly, and the water outlet end of the guide block 53 will be closed, thereby blocking the water flow inside the water tank 51 from continuing to be discharged. During the flipping process of the water receiving tank 561, the guide block 53 is prevented from continuing to fall into the water, and accidental leakage of exhaust gas inside the ceramic lining 31 is prevented.

[0054] like Figure 3 and Figure 7 As shown, an electromagnetic plate 547 is installed at the lower part of the fixed block 541, and a magnetic member 548 that can be magnetically attracted by the electromagnetic plate 547 is fixedly sleeved inside the closing plate 544.

[0055] Adopting the above scheme: when the water receiving box 561 is turned over, the water receiving box 561 will no longer abut against the abutment plate 543, and the pressure sensing element 542 will no longer be subjected to pressure. At this time, the control end will close the electromagnetic plate 547. Due to the closing of the electromagnetic plate 547, the electromagnetic plate 547 loses the magnetic attraction to the magnetic part 548. At this time, the second elastic part 546 is in the stretching state. Due to the recovery effect of the elastic force, the closing plate 544 will be driven to rise rapidly.

[0056] like Figure 2 and Fig. 9 As shown, it also includes a neutralization mechanism 6 and a water pump mechanism 7. The neutralization mechanism 6 is arranged inside the water storage mechanism 5, and the water pump mechanism 7 is installed outside the water storage mechanism 5;

[0057] The neutralization mechanism 6 includes a mounting frame 61, which is installed in the water tank 51. The mounting frame 61 has a mesh box 62 that is slidably connected to the inside of the mounting frame 61. Slaked lime 63 is placed in the mesh box 62. A filter plate 64 located above the mesh box 62 is provided inside the mounting frame 61. A connecting plate 65 located on the front of the water tank 51 is installed on the front of the mesh box 62. A row of heat dissipation holes 66 located between the movable water storage component 56 and the filter plate 64 are opened on the front of the water tank 51. The movable water storage component 56 can contact the sealing plate 55.

[0058] Adopting the above scheme: when the weakly acidic water in the water receiving box 561 is poured onto the filter plate 64, the waste particles in the acidic water will be filtered out, and then the acidic water will flow to the inside of the net box 62 to contact with the slaked lime 63, and the acidic water will be neutralized during the short contact, and then flow down to the bottom of the inside of the intermediate water tank 2 51. Since the acidic condensed water is weakly acidic after being diluted with the water source, the weakly acidic water here can be neutralized into a weaker acid or neutral or weak alkaline after a short contact with the slaked lime 63. A large amount of heat will be generated during the neutralization reaction, and part of the heat will be discharged through the heat dissipation holes 66, and part of the heat will be directly conducted to the water body, so as to maintain the temperature of the water body after neutralization;

[0059] When the slaked lime 63 needs to be replaced, the operator can pull the connecting plate 65 after the rotary kiln 2 stops operating, and can directly extract the mesh box 62 and the slaked lime 63, so that the slaked lime 63 can be replaced.

[0060] like Figure 2 and Fig. 9 As shown, the water pump mechanism 7 includes a corrosion-resistant water pump assembly 71, which is installed below the outer side of the water tank 2 51 and can be connected thereto. A delivery pipe 72 is fixedly connected above the corrosion-resistant water pump assembly 71, and the top of the delivery pipe 72 extends to the interior of the water tank 1 41.

[0061] By adopting the above scheme, due to the operation of the corrosion-resistant water pump assembly 71, the water in the lower part of the water tank 2 51 can be pumped back to the inside of the water tank 1 41 through the delivery pipe 72, thereby ensuring the adequacy of the water source inside the water tank 1 41 and forming a water circulation.

[0062] The working principle and use process of the present invention:

[0063] During the operation of the rotary kiln 2, the exhaust gas generated inside the rotary kiln 2 will enter the interior of the ceramic lining 31. At this time, the water inside the water tank 1 41 can flow down along the inner wall of the ceramic lining 31 through the water outlet 42 under the action of gravity, and pass through the bend of the ceramic lining 31 on the way, thereby quickly taking away the acidic condensed water accumulated at the bend of the ceramic lining 31, and at the same time, it can dilute the acidic condensed water, and the diluted acid water will flow along the pipe wall of the ceramic lining 31 into the interior of the water inlet interface 52, and enter the water tank 2 51 through the water inlet interface 52, thereby forming a continuous flow of water on the inner wall of the ceramic lining 31. The continuous flow of water can contact the flow of water before the waste particles touch the inner wall of the ceramic lining 31, thereby having a buffering effect on the impact of the waste particles, thereby greatly reducing the damage to the ceramic lining 31, and preventing the acidic condensed water from accumulating on the pipe wall of the ceramic lining 31 for a long time.

[0064] Since the heat-conducting ring 34 transfers the heat of the rotary kiln 2 to the ceramic lining 31 through the heat-conducting member 32, the temperature difference between the ceramic lining 31 and the inside of the rotary kiln 2 can be reduced. At the same time, the heat-conducting strip 43 transfers the temperature of the heat-conducting member 32 to the water tank 41 and heats the water, reducing the temperature difference between the water source sprayed from the water outlet 42 and the exhaust gas, thereby reducing the generation of condensed water.

[0065] When the weakly acidic flowing water enters the interior of the water tank 51, it will be guided to the water receiving box 561 through the guide block 53, so that the gravity of the water receiving box 561 increases. When the gravity of the water receiving box 561 is greater than the elastic force of the first elastic member 575, the clamping rod 573 will be squeezed by the water receiving box 561 and will shrink into the fixed block 571, and will be separated from the water receiving box 561, so that the water receiving box 561 will turn over. During the turning over of the water receiving box 561, the weakly acidic water in the water receiving box 561 will be poured onto the filter plate 64 to filter out the waste particles in the acid water. Then the acid water flows to the interior of the net box 62 and contacts with the slaked lime 63, and The acid water undergoes a neutralization reaction during a brief contact, and then flows down to the lower part of the interior of the medium water tank 2 51. Since the acidic condensed water is weakly acidic after being diluted with the water source, the weakly acidic water here can be neutralized into a weaker acid or neutral or weak alkaline after a brief contact with the slaked lime 63. A large amount of heat will be generated during the neutralization reaction. Part of this heat will be discharged through the heat dissipation holes 66, and part of the heat will be directly conducted to the water body, thereby maintaining the temperature of the water body after neutralization. Due to the operation of the corrosion-resistant water pump assembly 71, the water at the lower part of the interior of the water tank 2 51 can be pumped back to the interior of the water tank 1 41 through the delivery pipe 72, thereby forming a water circulation.

[0066] When the water receiving box 561 is flipped, the rotating arm 563 and the through hole 564 will rotate at the same time, and pull the piston 566 to move upward inside the movable cylinder 565. At this time, the gas inside the movable cylinder 565 will be discharged slowly through the through hole 564, thereby playing the role of damping the rise of the piston 566. At this time, the second elastic member 567 is stretched, and at the same time plays the role of damping the flipping of the water receiving box 561, so that the flipping speed of the water receiving box 561 is reduced. Since the flipping speed of the water receiving box 561 is reduced, the movable water storage assembly 56 can pour water relatively evenly every time it flips one degree, so that each screen surface of the filter plate 64 can be reasonably used, and at the same time, the slaked lime 63 spread in the mesh box 62 can be relatively evenly in contact with water, avoiding the slaked lime 63 on the right side and the right side of the filter plate 64 from being over-used after the water receiving box 561 is quickly flipped.

[0067] When the clamping rod 573 contracts into the fixed block 571, the movable block 572 and the movable rod 574 will move together, and the first elastic member 575 will be compressed. When the water receiving box 561 turns over, the water receiving box 561 will no longer abut against the abutment plate 543. At this time, the pressure sensing element 542 will no longer be subjected to pressure. At this time, the control end will simultaneously open the electromagnetic plate 577 and close the electromagnetic plate 1 547. Due to the opening of the electromagnetic plate 577, the electromagnetic plate 577 can generate suction on the magnetic member 576, thereby adsorbing the magnetic member 576 on the magnetic member 576. On the electromagnetic plate 2 577, the retracted clamping rod 573 and the movable block 572 are fixed at the same time. Due to the closing of the electromagnetic plate 1 547, the electromagnetic plate 1 547 loses the magnetic attraction to the magnetic part 1 548. At this time, the second elastic part 1 546 is in tension. Due to the recovery effect of the elastic force, the closing plate 544 will be driven to rise rapidly, and the water outlet end of the guide block 53 will be closed, thereby blocking the water flow inside the water tank 2 51 from continuing to be discharged. During the flipping process of the water receiving tank 561, the guide block 53 is prevented from continuing to fall into the water, and the risk of exhaust gas leakage is avoided.

[0068] When resetting: When the water in the water receiving box 561 is poured out, the second elastic member 567 can be used to pull the piston 566, the rotating arm 563 and the water receiving box 561 to quickly reset under the elastic recovery effect. At this time, the one-way flap 562 is stretched open by the negative pressure to increase the air intake. When the water receiving box 561 is reset to abut against the abutment plate 543, the pressure sensing element 542 is subjected to pressure. At this time, the control end will reopen the electromagnetic plate 1 547 and close the electromagnetic plate 2 577. Due to the opening of the electromagnetic plate 1 547, the electromagnetic plate 1 547 can generate magnetic attraction to the magnetic member 1 548, so that the magnetic member 1 548 drives the magnetic member 1 548 to move. The closing plate 544 and the slider 545 are lowered and reset, and at the same time, the second elastic member 546 continues to be stretched, releasing the closure of the water outlet end of the guide block 53, and allowing the weak acid water inside the guide block 53 to continue to flow into the water receiving box 561. Since the electromagnetic plate 577 is closed, the magnetic member 576 is no longer magnetically attracted by the electromagnetic plate 577. Under the elastic recovery action of the first elastic member 575, the movable block 572, the magnetic member 576 and the clamping rod 573 are pushed toward the water receiving box 561, and the clamping rod 573 continues to be clamped in the water receiving box 561, thereby fixing the water receiving box 561.
