The invention discloses a crushing and sorting device after integral pyrolysis of a power battery, which integrates four steps of feeding and pre-removing iron, crushing and screening, throwing and winnowing and high-voltage electrostatic fine sorting.
In the feeding and deironing stage in advance, the coarse crushed aggregates of the battery after preliminary crushing is put into through the feed inlet of the feeding device and falls on the magnetic conveying belt, and then in the process of horizontally conveying to the crushing cavity, the magnetic conveying belt can effectively adsorb and remove iron magnetic impurities (such as battery shell fragments) mixed in the materials, so that the impurity separation of the first step is completed.
In the stage of crushing and screening, coarse crushed materials fall between a pair of crushing rollers which synchronously rotate in opposite directions in a crushing cavity, are extruded and sheared to be crushed for the second time, the crushed materials directly fall on an inverted V-shaped screen plate under the crushing rollers, black powder and fine metal particles meeting the particle size requirement fall through screen holes, uncrushed and thorough metal sheets/blocks with larger size fall along the inclined planes of the screen plates and are discharged from leading-out side boxes on two sides, so that the primary separation of the coarse and fine materials is realized, and meanwhile, the screen plates can continuously vibrate at high frequency through a vibration generating mechanism to realize efficient screening and effectively prevent hole blocking.
In the stage of throwing and winnowing, air generated by the air compressor is sprayed out through an air inlet channel of a double-air-channel hollow shaft, blades in the pneumatic rotary drum are driven to rotate, and then the air is conveyed to air blowing pipes at two sides above through air outlet channels and is blown out downwards. Meanwhile, the wave-shaped guide closed ring groove of the outer wall of the pneumatic rotary drum converts the rotary motion of the rotary drum into the up-and-down reciprocating swing of the material throwing plate through the guide wheel, the double-sided rack and the gear set. The falling material is firstly winnowed by the air flow of the air blowing pipe, and then falls on the swinging material throwing plate to be evenly thrown and dispersed to form a 'material curtain'. During the process of throwing the material, the airflow of the air blowing pipe carries out secondary and more sufficient air separation on the material. Impurities such as a diaphragm, plastic and the like with lighter mass are blown to the side by air flow, captured and removed by a negative pressure suction pipe group, and black powder and metal scraps with heavier mass overcome the influence of the air flow and continuously fall into the high-voltage electrostatic separation cavity. The process increases the contact area and time between the materials and the air flow through secondary throwing, and realizes the efficient removal of light impurities.
In the high-voltage electrostatic fine separation stage, the fallen black powder and metal mixture slides to the high-voltage electrostatic separation assembly along the material guide plate, all materials are charged with electrostatic charges through the high-voltage electrostatic plate area, and then the materials fall onto the rotating high-voltage electrostatic roller.

And finally, scraping the material shoveling plate which rotates to the lower part along with the high-voltage electrostatic roller, and falling into a black powder collecting hopper to finish the final black powder purification.
The invention completes the separation of pyrolytic black powder and various impurities such as iron, aluminum, copper, diaphragm and the like one by one in a vertical integrated device in high efficiency and continuously through the series of annular-ring phase-buckling procedures of magnetic separation, crushing, screening, pneumatic throwing winnowing and electrostatic separation, and finally obtains the black powder product with high purity.
Compared with the prior art, the invention has the following beneficial effects:
The invention has high integration and flow process degree, and integrates a plurality of functional modules such as magnetic separation iron removal, crushing, screening, winnowing, electrostatic separation and the like into the vertical shell, so that continuous and automatic treatment from feeding to pure black powder obtaining of the battery materials after pyrolysis is realized, and the occupied area of equipment and the energy consumption and loss caused by material transportation are obviously reduced.
The invention has excellent separation efficiency and effect, on one hand, the pneumatic driving material throwing and directional air flow air separation are realized by utilizing a unique material throwing air separation mechanism by utilizing the same air source, so that materials are fully dispersed and contacted with air flow in the process of being thrown up and scattered by a material throwing plate for multiple times, the high-efficiency and multiple separation of light impurities (such as a diaphragm) and heavier black powder/metal is realized, the separation effect is far better than that of single air separation, meanwhile, the core power of the material throwing air separation mechanism is derived from compressed air, the energy for driving mechanical movement and the energy required by air separation are combined into one through the design of 'one air two-use', the whole energy consumption is reduced, and on the other hand, the high-voltage electrostatic separation is applied to the separation of black powder and metal chips (such as copper and aluminum), a small amount of mixed metal is accurately removed from the black powder by utilizing the great difference of conductivity of the two, the difficult problem that the traditional eddy current separation has poor separation effect on tiny and flaky metal is solved, and the separation and purification effect of the black powder is effectively improved.
The invention further considers the characteristics of the pyrolyzed material (such as possible coking and adhesion), and equips the sieve plate with a special vibration generating mechanism, so that the sieve plate can effectively prevent sieve holes from being blocked, ensure sieving efficiency, and the whole system runs in a closed shell, combines negative pressure suction, effectively controls dust, improves working environment and ensures production safety.

The specific operation process and principle of the crushing and sorting device after the integral pyrolysis of the power battery disclosed in the embodiment 1 are as follows:
Firstly, the power battery is put into the magnetic conveying belt 302 through the feed inlet 303 after preliminary crushing, and when the magnetic conveying belt 302 conveys the coarse crushed aggregates after preliminary crushing to the upper parts of the two crushing rollers 5, the magnetic conveying belt 302 can also adsorb and remove iron impurities in the coarse crushed aggregates.
When the coarse crushed materials fall between the roller gap of the two crushing rollers 5, the two crushing rollers 5 synchronously and reversely move under the action of the power assembly 6, so that the coarse crushed materials are crushed into smaller crushed materials for the second time, and then fall into the middle of the sieve plate 7. The secondary crushed material falling on the screen plate 7 can slide downwards to the left and the right, and when the secondary crushed material passes through the screen hole 701 area, small particle materials can be screened and fall down, and most of the non-screened materials are metal fragments, and the metal fragments can finally fall into the guiding-out side box 8 to be discharged.
In the operation process of the material throwing and winnowing mechanism 9, high-pressure air flow is continuously provided by the air compressor 902, the high-pressure air flow firstly enters the air inlet channel 9051 of the double-air-passage hollow shaft 905 from the bottom, then is discharged from the air outlet 9053 and acts on the blades 9041 on the inner wall of the pneumatic rotary drum 904, so that the pneumatic rotary drum 904 is driven to rotate around the double-air-passage hollow shaft 905, then the air flow in the pneumatic rotary drum 904 enters the air outlet channel 9052 of the double-air-passage hollow shaft 905 through the air inlet 9054, is discharged from the top of the double-air-passage hollow shaft 905, is uniformly distributed into the air blowing pipes 908 on two sides by the air flow distributor 907, and is finally discharged from the air blowing pipes 908. During the rotation of the pneumatic drum 904, the double-sided racks 910 on the front and rear sides can reciprocate up and down synchronously under the action of the guide closed-loop groove 9042 and the guide wheel 911, and then the up and down swing of the flitch 914 is realized through the meshing transmission between the double-sided racks 910 and the gear 912. At this time, the sieved particulate material is blown by the exhaust air flow in the air blowing pipe 908 in the falling process, so as to separate light impurities from the black powder, and then the black powder falls onto the throwing plate 914 and is thrown up again, and is blown by the exhaust air flow in the air blowing pipe 908 again, so as to achieve secondary air separation and impurity removal of the light impurities in the black powder, finally the light impurities are pumped by the negative pressure suction pipe 915, and the black powder and metal fragments thereof fall into the high-voltage electrostatic separation cavity 24.
When the black powder and metal scraps thereof slide down to the position of the high-voltage electrostatic separation assembly 11 along the guide plate 10, the high-voltage electrostatic plate 113 can charge both the black powder and the metal scraps and then fall onto the high-voltage electrostatic roller 111, at the moment, the metal scraps have good conductivity and can quickly restore the charge to neutrality, so that the metal scraps are not adsorbed by the high-voltage electrostatic roller 111 and fall into the metal scraps receiving groove 12 under the rotation of the high-voltage electrostatic roller 111, the black powder conductivity is poor, the charge cannot be transferred in time, so that the black powder is adsorbed by the high-voltage electrostatic roller 111, and then the black powder and the metal scraps finally fall into the black powder collecting hopper 4 to be collected by the shovel plate 114 as the high-voltage electrostatic roller 111 rotates to the position of the shovel plate 114, so that the effective separation of the black powder and all impurities is finally realized.
