Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery separation, in particular to a battery crushing material separation screen capable of hierarchical screening and a use method thereof. BACKGROUND

[0002] The battery crushing material separation screen capable of hierarchical screening is a key equipment specially used for lithium battery recycling, and its core function is to accurately classify and preliminarily separate the battery mixture after crushing. The equipment usually uses multiple layers of screens with different hole diameters, and through vibration, rotation or other mechanical movements, the crushed materials with complex composition and different particle sizes (including black powder, current collector fragments, diaphragm, shell material, etc.) are effectively separated according to particle size, such as coarse, medium and fine materials. Its important role mainly reflects in three aspects: first, it realizes accurate classification and provides uniform particle size raw materials for subsequent processes, avoiding interference between different size materials; second, it preliminarily enriches valuable components, such as electrode active material (black powder) in fine particles, and more metal such as copper and aluminum foil in coarse particles, thereby greatly improving the efficiency and purity of subsequent separation (such as flotation and magnetic separation); third, it removes fine powder or large impurities through early screening, which can effectively protect downstream equipment, reduce wear and blockage, ensure the continuous and stable operation of the entire recycling production line, and ultimately improve the overall recovery rate and economic value of valuable metals.

[0003] The existing battery crushing material separation screen still has many limitations: the traditional battery crushing material separation screen is vibrated continuously to make the battery crushing material fall into the collection box through the holes in the screen or screen cylinder, but during the screening process, larger materials will inevitably get stuck in the holes of the screen or screen cylinder, making it difficult for the following materials to be normally screened, affecting the smoothness of the screening; ordinary battery crushing material separation screen can only screen smaller materials, leaving larger materials in the screening mechanism, which need to be manually removed, making it difficult to achieve simultaneous material separation and affecting the screening efficiency; the existing battery crushing material separation screen forms a local stack after the material is screened and falls into the collection box, which requires manual flattening of the stacked material, consuming time and effort, affecting work efficiency, and also affecting the discharging efficiency.

[0031] A method for using a battery crushing material separation screen capable of graded screening comprises the following steps: S1: When the equipment is started, the motor 103 drives the rotating rod 104 at the output shaft end to rotate, so that the rotating rod 104 drives the fixedly connected gear A105 to rotate, and then the gear A105 engages with the gear B107 for transmission, so that the gear B107 drives the screen drum 108 fixedly connected to it to rotate around the fixed rod 106, and the battery crushed material is put into the feed port of the screen drum 108. As the screen drum 108 rotates, the material rolls continuously in the drum; S2: The device is equipped with a dredging mechanism 2. A protrusion 201 is fixed on the outer circumference of the screen drum 108. As the screen drum 108 rotates, it periodically squeezes the force-bearing rod 204 in the device sleeve 202. The force-bearing rod 204 is L-shaped with a bevel at one end. After being squeezed, it slides along the inner wall of the device sleeve 202 and compresses the spring telescopic rod 203 through the short rod 205. When the protrusion 201 rotates away, the spring telescopic rod 203 pushes the force-bearing rod 204 to return to its original position. S3: The dividing mechanism 3 performs a secondary dividing operation. The dividing rod 301 fixed on the fixed rod 106 remains stationary with the fixed rod 106. Its L-shaped structure and the design of the three circular arrays can move the material in the screen drum 108 to promote tumbling screening. At the same time, the rotation of the screen drum 108 drives the fixed plate 303 fixed therein to rotate, and the fixed plate 303 drives the reciprocating screw 302 to rotate, so that the reciprocating screw 302 drives the threaded sleeve 304 on it to reciprocate on the reciprocating screw 302.

[0032] Working principle: when the device starts, the motor 103 drives the output shaft end of the rotating rod 104 to rotate, so that the rotating rod 104 drives the fixed connection gear A 105 to rotate, and then the gear A 105 and the gear B 107 are engaged to drive the gear B 107 to rotate around the fixed rod 106, and the battery crushing material is put into the sieve cylinder 108 from the feeding port, and with the rotation of the sieve cylinder 108, the material is continuously tumbled in the cylinder, and the material smaller than the aperture of the sieve cylinder 108 falls through the sieve hole under the action of gravity and centrifugal force, realizing preliminary classification and screening. In order to improve the screening efficiency and prevent blockage, the device is provided with a dredging mechanism 2, and a protrusion 201 is fixed on the outer circumference of the sieve cylinder 108, which periodically extrudes the stressed rod 204 in the device sleeve 202 with the rotation of the sieve cylinder 108. The stressed rod 204 is L-shaped and has a slope at one end. After extrusion, it slides along the inner wall of the device sleeve 202, and through the short rod 205, the spring telescopic rod 203 is compressed. When the protrusion 201 rotates away, the spring telescopic rod 203 pushes the stressed rod 204 back to its original position. The torsional spring A 206 on the short rod 205 ensures that the push rod 207 always has a tendency towards the sieve cylinder 108. The end of the push rod 207 is also designed with a slope, which can be inserted into the hole of the sieve cylinder 108 when it is reset, pushing the jammed material back into the cylinder, realizing dynamic dredging and ensuring smooth screening. For large size materials that cannot pass through the sieve cylinder 108, the material distribution mechanism 3 performs secondary material distribution operation. The material distribution rod 301 fixed on the fixed rod 106 is stationary with the fixed rod 106. Its L-shaped structure and three circumferential array design can move the material in the sieve cylinder 108, promote tumbling and screening. At the same time, the rotation of the sieve cylinder 108 drives the fixed plate 303 fixed in it to rotate, which drives the reciprocating wire rod 302 to rotate, so that the reciprocating wire rod 302 drives the threaded sleeve 304 on it to reciprocate on the reciprocating wire rod 302, and then drives the push plate 305 to push the large particles in the sieve cylinder 108 to the baffle 308. When the material reaches the end of the sieve cylinder 108, it pushes the baffle 308, which is fixed on the long rod 306 and opens under the push force to overcome the torque of the torsional spring B 307, so that the material slides down the inclined plate 309 and falls into the material box A 310 in the base 102 for collection, realizing automatic separation of the un-screened material. In addition, the device also integrates a vibration mechanism 4 to optimize the collection process. The push block 404 fixed on the hinged hatch 109 of the sieve cylinder 108 periodically pushes the slide rod 405 with the rotation of the sieve cylinder 108. The slide rod 405 is fixed with the material box B 402, which is used to receive the fine materials falling from the hole of the sieve cylinder 108. The slide rod 405 is pushed to overcome the spring force of the spring 401 to move the material box B 402 outward. After the push block 404 rotates away, the spring 401 pulls the material box B 402 to reset quickly. Such high-frequency vibration prevents the accumulation of fine materials in the box, promotes the even distribution of materials, and improves the collection efficiency and capacity. The separation sieve realizes preliminary screening of materials through the rotation of the sieve cylinder 108, combines the anti-blocking mechanism 2, the material distribution mechanism 3 to separate large particle materials, and the vibration mechanism 4 to optimize the collection.It achieves efficient and continuous separation of battery crushed materials, improving overall work efficiency and reliability.
