Description
Technical Field
The invention relates to waste lithium battery recycling and screening equipment, in particular to a feeding control device of the waste lithium battery recycling and screening equipment.
Background
In order to better realize the screening of the recycled materials of lithium ion batteries, the applicant filed a screening device for crushed waste lithium ion battery electrode materials of patent CN 202010565128.8. The device comprises a shell, wherein a feeding port is formed in the middle of the upper end of the shell, a horizontal screen is arranged in an inner cavity of the shell, a vibrating device is arranged below the screen, and corresponding discharging ports are formed in the shell above and below the screen; the casing is including the sorting cylinder of the straight tube-shape that is located the lower part, still including the overhead guard that is located the frustum form of upper end, wherein, can dismantle the connection between overhead guard and the sorting cylinder, and the pan feeding mouth sets up at the overhead guard middle part, and the sorting cylinder inner wall is provided with the screen cloth mounting structure who is used for installing the screen cloth, screen cloth mounting structure includes a horizontal installation at the inboard collar of casing, and the inboard concave screen cloth installation step that is formed with of collar upper surface, screen cloth detachably cooperation are installed in screen cloth installation step. The invention has the advantages of improving the screening effect of equipment, prolonging the service life of the screen and better improving the recovery and treatment efficiency of the battery electrode.
The above screening devices still suffer from the following drawbacks: 1 the device adopts circular shape screen cloth, pours the material into screen cloth middle part earlier, and the screen cloth leans on the even vibration realization screening that the vibrator provided, and the material is followed the peripheral one side ejection of compact of screen cloth after the screening. The screen cloth is that the marginal position vibration effect that links to each other with the vibrator is better like this, and intermediate position vibration effect is relatively poor, but the material drops the relatively poor intermediate position of vibration effect earlier, shakes the diffusion to week side from the centre again, so have screening and discharge efficiency lower, even vibration screening effect defect such as relatively poor. 2. The device can sieve out the material granule that the particle diameter is different betterly, but battery electrode material after the breakage can contain different compositions such as metal material, positive negative pole material and diaphragm material, and the material of these different compositions mixes together, can't sieve apart, can influence subsequent recovery processing.
In order to solve the two defects, the applicant further improves the two points, designs two different screening modes and respectively applies for patent protection. One of them modified screening mode is that lets in the air current in the screening plant for the screen cloth department of co-altitude not forms the air current atmospheric pressure of equidimension from the bottom up, and then can assist the sorting screening that realizes the same particle size but different material composition granular materials. However, the feed port of the original equipment is directly communicated with the outside atmosphere, which can cause air pressure leakage, so that the equipment is obviously not suitable for a new screening mode, and the feed structure needs to be further improved to improve the feed control effect. The second improved screening mode is that the screen is screened in a single-end vibration mode, and the material moves from one end of the screen to the other end in the screening process by means of the single-end vibration of the screen, so that the flowing water type screening is realized; such screening mode can match with the broken granule appearance of lithium ion battery material (have a large amount of concave polygons even V-arrangement structure granule and hang on the screen cloth easily) better, and the thickness condition is piled up to the material above the screen cloth and vibration range size can perfectly match simultaneously, so can improve screening effect and efficiency better. However, in the screening mode, the screen is single-end vibrating, so the refining effect of the screen is poor, and the feed inlet of the original equipment feeds from the middle position of the middle part of the equipment, so the screening mode is obviously not matched and corresponds to the screen, and the feed structure needs to be further improved, so that the single-side feeding can be better realized, and the primary refining effect is achieved.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a feeding control device which can conveniently control feeding and can form an air pressure sealing effect on a lithium ion battery screening chamber; and further make it can produce preliminary refining effect in the feeding process to match with the screening mode of single-end screening, improve final material screening efficiency and effect. The invention also discloses lithium ion battery recycling and screening equipment adopting the feeding control device, so that the lithium ion battery recycling and screening equipment has better material screening treatment effect and efficiency.
In order to solve the technical problem, the invention adopts the following technical scheme:
the utility model provides a feeding controlling means, including the feed inlet that is located lithium ion battery recovery screening equipment's screening roof portion, its characterized in that still includes a feeding case, the cylinder feeding chamber that has a level setting in the feeding case, cylinder feeding chamber one end top intercommunication is provided with a feed hopper, the other end connects the feed inlet downwards, the cooperation is provided with the feeding screw axle in the cylinder feeding chamber, the feeding screw axle is for being provided with the pivot with the helical blade that cylinder feeding chamber inner chamber matches, feeding screw axle one end links to each other with feeding power equipment.
Like this, during the feeding, not only can realize the feeding control better by the feeding of feeding screw axis, more importantly can realize that the feeding is sealed, avoids screening case inner chamber air pressure air current to spill the pressure release from feed inlet department, and influence the filtration and divide the sieve. Meanwhile, in the conveying process, due to extrusion, the caking of the electrode material can be pressed open, so that the electrode material is convenient to screen.
Furthermore, the feeding box is arranged between the end part of the cylindrical feeding cavity and the feeding hole, a long-strip-shaped refining cavity is arranged in the cylindrical feeding cavity and is perpendicular to the cylindrical feeding cavity, the lower surface of the end part of the cylindrical feeding cavity, which is positioned above the feeding hole, is provided with an outlet which is connected with the middle part of the refining cavity, the length direction of the refining cavity is arranged along the width direction of the screening box, a refining shaft is arranged in the refining cavity along the length direction of the refining shaft, two groups of opposite refining spiral blades are symmetrically arranged on the refining shaft, and the feeding hole is arranged below the refining cavity along the length direction of the refining cavity.
Therefore, when the feeding box works, the feeding screw shaft rotates to drive the leaked materials of the feeding funnel to move to the middle of the refining cavity in order, and meanwhile, the refining shaft rotates to convey the materials uniformly from the middle to two ends by means of the refining screw blades symmetrically arranged on the refining shaft and fall into the feeding end of the screen from the feeding port below. Therefore, the materials can fall into the screen along the width direction from the feeding end of the screen better, and the uniformity of feeding is improved. The reliability and the efficiency of screen cloth screening can be improved more.
Furthermore, the tail end of the feeding screw shaft penetrates through the cylindrical feeding cavity and is fixedly provided with a driving bevel gear, the driving bevel gear is positioned in a transmission cavity inside the feeding box and is meshed with a vertically arranged driven bevel gear, the driven bevel gear is coaxially and fixedly provided with a driving gear, the driving gear is downwards meshed with a driven gear, and a mounting shaft of the driven gear is in transmission connection with the end part of the refining shaft through a synchronous belt.
Therefore, when the feeding screw shaft rotates, the transmission of the pair of bevel gears and the pair of circular gears which are meshed with each other at the tail end of the feeding screw shaft can be relied on, and the rotation is transmitted to the refining shaft by the synchronous belt, so that only one power device is needed, the feeding screw shaft and the refining shaft can be driven to rotate simultaneously, the transmission structure is simplified, the number of the power devices is reduced, and the transmission consistency of the screw shaft and the refining shaft is improved.
Further, the middle part of the feed inlet is narrow and the width of the middle part is gradually widened towards the two sides.
Therefore, because the materials in the feeding cavity fall into the material homogenizing cavity from the middle part of the material homogenizing cavity, the middle part of the feeding port can fall into more materials more easily, the width of the middle part of the feeding port is narrowed, and the two ends of the feeding port are gradually widened, so that the falling materials of the feeding port can be more uniformly distributed. The reliability and the efficiency of screen cloth screening can be improved more. The material just so can begin to fall the feed end of screen cloth along screen cloth width direction whole uniformly, and the whole screen cloth feed end that follows after the vibration again removes to the discharge end, realizes the screening, so greatly improved the efficiency and the reliability of screening.
The invention also discloses lithium ion battery recycling and screening equipment which comprises a screening box, wherein the top of the screening box is provided with the feeding control device, a plurality of layers of horizontally arranged screens are arranged in the screening box at intervals up and down, a screen vibrating device is also arranged in the screening box and connected with each layer of screen, and a discharge barrel is arranged on the screening box at one side of each layer of screen; an air inlet pipe is also communicated and arranged on the side wall of the screening box below any screen.
Like this, during the broken back material granule got into screening case inner chamber from the feed inlet, rely on screen cloth vibration to realize screening, rely on the intake pipe to admit air during the screening for screen cloth below atmospheric pressure is great, and guide atmospheric pressure air current upwards passes the filter screen, and the granule that can proportion is bigger passes the filter screen and leaks the ejection of compact down, realizes the screening to the material. Simultaneously, because old and useless lithium ion battery self characteristic, the breakage is the particulate matter in-process, can produce the granular material that a large amount of concave polyhedrons even directly are V-arrangement structure, and this kind of structure articulates on the screen cloth very easily at the screening in-process and causes the jam, and lets in air current atmospheric pressure below the screen cloth, can upwards jack-up the V-arrangement granular material who articulates under the atmospheric pressure effect, can prevent it better to block up the screen cloth, keeps the smooth and easy of screening going on.
Furthermore, screening case horizontal cross-section and screen cloth are the rectangle that corresponds, and screen cloth length direction's one end is the discharge end, and the discharge end is shelved on the screen cloth mount table of screening incasement wall and is linked up with the play feed cylinder, and screen cloth length direction's the other end is the feed end, and the feed end and the screen cloth vibrating device of screen cloth link to each other and can be driven vertical vibration, and set up on the screening incasement face of screen cloth feed end top the feed inlet.
Therefore, when materials are fed, the materials fall into the screen from the feeding end of the screen, the single end of the feeding end of the screen vibrates, the materials are gradually shaken from the feeding end to the other end to be gathered to the discharging port for discharging, and the moving water-flowing type screening discharging is realized in the process, so that the material screening process and the moving process are combined, and the screening efficiency is better improved. Meanwhile, in the screening mode, when the materials fall from the feeding end of the screen, the quantity of the materials is large, the end correspondingly vibrates to be large (amplitude), when the materials move to the discharging end from the feeding end of the screen, the quantity of the materials is gradually reduced along with the falling of the materials, and the vibration of the screen is also gradually reduced corresponding to the amplitude, so that the movement running water type screening can be better realized, and the screening and falling movement condition in the material advancing process can be perfectly matched with the vibration size condition. Therefore, the screening effect and the screening efficiency can be better improved. In addition, the screening mode of single-end vibration also enables V-shaped particle materials hung on the screen to shake and fall off due to unbalanced stress on two sides more easily, so that blockage can be better avoided.
Further, the screen vibrating device comprises a motor located outside the screening box, an unfilled gear is installed on a motor output shaft along the vertical direction, the periphery of the unfilled gear is only provided with one section of gear teeth, an unfilled gear outer frame is provided with a transmission gear frame capable of moving up and down, two sides of the inner wall of the transmission gear frame are respectively provided with a rack, the gear teeth on the unfilled gear rotating shaft to the corresponding direction can be meshed with the corresponding rack and drive the transmission gear frame to move up and down, a driving connecting plate is fixedly connected to the lower end of the transmission gear frame downwards, the driving connecting plate is connected with a horizontal connecting plate horizontally arranged, the horizontal connecting plate horizontally penetrates through a perforation located on the side wall of the screening box and a baffle fixedly connected with the vertical setting, a screen fixing table is installed in the middle of one side of the baffle facing the screen and is connected with the feeding end of the screen, and one side of the baffle facing away from the screen is attached to the inner side wall of the screening box and can shield the perforation.
Like this, motor output rotates and drives the rotation of scarce tooth gear, through the meshing in turn of scarce tooth gear and two inboard racks of transmission tooth frame, drives transmission tooth frame reciprocating up-and-down motion (lack tooth gear promptly and begin to mesh with the unilateral rack meshing the same time, and then drive horizontal connecting plate reciprocating up-and-down motion through the drive connecting plate, the realization is to the single-ended vibration of screen cloth feed end. Therefore, the vibration power can be transmitted reliably and efficiently.
Furthermore, a horizontal connecting plate mounting hole is formed in one end, connected with the horizontal connecting plate, of the driving connecting plate, the end part of the horizontal connecting plate can be assembled in the horizontal connecting plate mounting hole in a vertically moving mode, and when the horizontal connecting plate is in an initial moving state, the end part of the horizontal connecting plate is attached to the lower surface of the horizontal connecting plate mounting hole and a section of space is reserved between the end part of the horizontal connecting plate and the upper surface of the horizontal connecting plate mounting hole; when the horizontal connecting plate moves to the horizontal state of the screen, the middle position of the gear teeth of the gear with missing teeth is meshed with the middle position of the rack on the corresponding side.
Like this, after drive connecting plate upward movement and drive horizontal connecting plate upwards to the summit, because still leave one section interval between horizontal connecting plate tip and the horizontal connecting plate mounting hole upper surface, the horizontal connecting plate leaves the space that continues upward movement under the inertia effect during this time, and horizontal connecting plate can break away from drive connecting plate restraint and continue to contact and driven downward movement with horizontal connecting plate mounting hole upper surface after upward movement a small distance again. Therefore, the upward movement amplitude of the horizontal connecting plate is larger than the downward movement amplitude in the vibration process. Therefore, the materials on the screen can be better driven to move from the feeding end to the discharging end gradually while being screened, and the screening in a flow line mode is realized.
Furthermore, a vertically arranged amplitude-variable spring is fixedly connected in the through hole and between the horizontal connecting plates.
Therefore, because the lithium battery shell and the electrodes are both of the flat-plate structures, after the lithium battery shell and the electrodes are crushed into particles by the crushing mechanism, the particles are different from conventional particles which are convex polyhedrons, a large number of concave polyhedrons can be generated, and even a large number of particles which are directly in V-shaped structures can be generated. Therefore, in the screening process, the concave polyhedron and even the particles with V-shaped structures are easy to be hung on the screen, and the screen is easy to be blocked. The amplitude-variable spring can cooperate with the space left between the upper surface of the end part of the horizontal connecting plate and the mounting hole of the horizontal connecting plate, so that the horizontal connecting plate can generate small elastic movement with at least one reciprocating period under the action of inertia of the amplitude-variable spring in a short time after the horizontal connecting plate moves upwards to the moment of separation. Therefore, the horizontal connecting plate generates amplitude-variable vibration with small amplitude when vibrating upwards to the highest point and is driven to vibrate downwards. So reciprocal, the screen cloth is downward at the drive of dual variation of amplitude vibration, compares with single amplitude vibration mode, can shake off the V-arrangement granule of hanging on the screen cloth better, can greatly improve the screening effect. Meanwhile, the rotation with small amplitude is generated after the vibration with large amplitude reaches the highest point, so that the effect of driving the materials on the screen to flow towards the direction of the discharge end can be improved.
Furthermore, the upper surface of the horizontal connecting plate mounting hole is detachably and fixedly connected with a cushion block by a screw. Like this, can conveniently adjust cushion thickness to the size of interval between adjustment horizontal connecting plate tip and the horizontal connecting plate mounting hole upper surface, so that above-mentioned process can be adjusted and realized smoothly, also conveniently change the restoration after wearing and tearing lead to the effect variation.
Furthermore, a transmission box is arranged on the outer side of the screening box, and the tooth-lacking gear, the transmission gear frame and the driving connecting plate are located in the transmission box. This can improve the protective effect on the transmission mechanism better.
Furthermore, one end of the feeding screw shaft is connected with an output shaft of the motor, and the motor forms the feeding power equipment. Therefore, three power parts of the whole equipment are driven by only one motor, and the equipment device is greatly simplified.
Furthermore, the lower extreme in the screening case outside is provided with the supporting leg.
Further, the screen cloth includes first screen cloth, second screen cloth and the third screen cloth that from the top down set up, and the third screen cloth below is just to the level grafting be provided with the case that gathers materials that can extract, and the intercommunication is provided with first outlet duct on the screening case lateral wall between first screen cloth and the second screen cloth, and the intercommunication is provided with the second outlet duct on the screening case lateral wall between second screen cloth and the third screen cloth, and the intercommunication is provided with on the screening case lateral wall between third screen cloth and the case that gathers materials the intake pipe.
Like this, the intake pipe enters into the box from third screen cloth below, forms ascending air current atmospheric pressure under the outlet duct guide effect, then partial air current flows out the pressure release from the second outlet duct between second screen cloth and the third screen cloth, and remaining part air current atmospheric pressure continues upwards to pass through the second screen cloth, flows out the pressure release from the first outlet duct between second screen cloth and the first screen cloth. This results in no upward air flow pressure on the first screen and a gradual increase in upward air flow pressure on the second to third screens. So the material enters into first screen cloth after, can realize the normal screening of once earlier for satisfy the material that the granule particle size required and leak down from first screen cloth, the ejection of compact section of thick bamboo ejection of compact of the great material of granule from first screen cloth right side. Then the materials meeting the requirement of the granularity fall onto a second screen, and are subjected to air pressure airflow in a certain direction while being subjected to vibrating screening by the second screen, so that lighter materials (the main part of the membrane material) stay above the second screen and are finally discharged from a corresponding discharge cylinder. The rest materials fall into the third screen downwards, are subjected to larger upward air pressure airflow while being subjected to vibratory screening by the third screen, so that the light materials (the anode and cathode materials are main parts, such as lithium cobaltate, ternary materials, graphite materials and the like) stay above the third screen and are finally discharged from the corresponding discharge barrel. Finally, the heaviest remaining material (mainly made of metal material) passes through the third screen downwards and falls into a collecting box. Therefore, the screening of materials with different specific gravities according to different materials can be better finished.

Therefore, the vibration power can be transmitted reliably and efficiently.
Wherein, one end of the driving connecting plate, which is connected with the horizontal connecting plate, is provided with a horizontal connecting plate mounting hole 11, the end part of the horizontal connecting plate 3 can be assembled in the horizontal connecting plate mounting hole 11 in a way of moving up and down, and when the horizontal connecting plate 3 is in an initial state of movement, the end part of the horizontal connecting plate is attached to the lower surface of the horizontal connecting plate mounting hole and is spaced from the upper surface of the horizontal connecting plate mounting hole 11; when the horizontal connecting plate 3 moves to the screen horizontal state, the middle position of the gear teeth of the gear with missing teeth is meshed with the middle position of the rack on the corresponding side.
Like this, after drive connecting plate upward movement and drive horizontal connecting plate upwards to the summit, because still leave one section interval between horizontal connecting plate tip and the horizontal connecting plate mounting hole upper surface, the horizontal connecting plate leaves the space that continues upward movement under the inertia effect during this time, and horizontal connecting plate can break away from drive connecting plate restraint and continue to contact and driven downward movement with horizontal connecting plate mounting hole upper surface after upward movement a small distance again. Therefore, the upward movement amplitude of the horizontal connecting plate is larger than the downward movement amplitude in the vibration process. Therefore, the materials on the screen can be better driven to gradually move from the feeding end to the discharging end while being screened, and the screening in a flow line mode is realized.
Wherein, a vertically arranged amplitude-variable spring 5 is fixedly connected in the through hole and between the horizontal connecting plates.
Therefore, because the lithium battery shell and the electrodes are both of the flat-plate structures, after the lithium battery shell and the electrodes are crushed into particles by the crushing mechanism, the particles are different from conventional particles which are convex polyhedrons, a large number of concave polyhedrons can be generated, and even a large number of particles which are directly in V-shaped structures can be generated. Therefore, in the screening process, the concave polyhedron and even the particles with V-shaped structures are easy to be hung on the screen, and the screen is easy to be blocked. The amplitude-variable spring can cooperate with the space left between the upper surface of the end part of the horizontal connecting plate and the mounting hole of the horizontal connecting plate, so that the horizontal connecting plate can generate small elastic movement with at least one reciprocating period under the action of inertia of the amplitude-variable spring in a short time after the horizontal connecting plate moves upwards to the moment of separation. Therefore, the horizontal connecting plate generates amplitude-variable vibration with small amplitude when vibrating upwards to the highest point and is driven to vibrate downwards. So reciprocal, the screen cloth is downward at the drive of dual amplitude of fluctuation vibration, compares with single amplitude vibration mode, can be better with hanging the V-arrangement granule shake-off on the screen cloth, can greatly improve the screening effect.
