Description

Technical Field

[0001] This invention relates to the field of battery separation technology, specifically to a graded screening sieve for separating crushed battery materials and its application method. Background Technology

[0002] A gradeable battery crushing material separator is a key piece of equipment specifically designed for lithium battery recycling. Its core function is to accurately classify and pre-sort the crushed battery mixture based on particle size. This equipment typically uses multiple layers of screens with different apertures. Through vibration, rotation, or other mechanical motion, it effectively separates the complex composition and varying particle sizes of the crushed material (including black powder, current collector fragments, separators, and casing materials) according to particle size, for example, into coarse, medium, and fine grades. Its important functions are mainly reflected in three aspects: First, it achieves precise grading, providing uniformly sized raw materials for subsequent processes and avoiding interference between materials of different sizes; second, it pre-enriches valuable components, such as fine particles containing electrode active materials (black powder), while coarse particles contain more metals like copper and aluminum foil, thus significantly improving the efficiency and purity of subsequent sorting (such as flotation and magnetic separation); third, by removing extremely fine powder or excessively large impurities through pre-screening, it effectively protects downstream equipment, reduces wear and clogging, ensures the continuous and stable operation of the entire recycling production line, and ultimately improves the overall recovery rate and economic value of valuable metals.

[0003] Existing battery crushing material separating screens still have many limitations: Traditional battery crushing material separating screens work by continuously vibrating the screen or screen cylinder to allow the crushed battery material to fall through the holes in the screen or screen cylinder into the collection box. However, during the screening process, larger pieces inevitably appear, which can get stuck in the holes of the screen or screen cylinder, making it difficult to screen subsequent materials and affecting the screening flow. Ordinary battery crushing material separating screens can only screen out smaller materials, leaving larger materials behind in the screening mechanism, requiring manual removal, making it difficult to achieve simultaneous material separation and affecting screening efficiency. Existing battery crushing material separating screens cause local accumulation of material after it is screened and falls into the collection box, requiring manual leveling of the piled material, which is time-consuming and labor-intensive, affecting work efficiency and material discharge efficiency. These defects seriously affect screening efficiency and screening flow.

[0004] In view of this, we propose a graded screening separation screen for battery crushed materials and its application method. Summary of the Invention

The force-bearing rod is slidably connected to the inner wall of the device sleeve. The screen cylinder is located on the displacement trajectory of the push rod, and the end of the push rod near the screen cylinder has an inclined surface.

[0009] Preferably, the material distribution mechanism further includes a material distribution rod, which is fixedly connected to the circumferential surface of a fixed rod. A threaded sleeve is threadedly connected to the end of the reciprocating screw away from the fixed plate. A push plate is fixedly connected to one side of the threaded sleeve. A long rod is rotatably connected to the end of the screen cylinder near gear B. A torsion spring B is fixedly sleeved on the outer surface of the long rod. A baffle is fixedly connected to the circumferential surface of the long rod. An inclined plate is fixedly connected to the side of the base near the base. A material box A is slidably connected to the inner wall of the base. A telescopic sleeve is provided on the outer surface of the reciprocating screw.

[0010] Preferably, one end of the torsion spring B is fixedly connected to the long rod, the other end of the torsion spring B is fixedly connected to the baffle, the inclined plate is located inside the base, the inclined plate is located below the baffle, the inclined plate is located above the material box A, one end of the telescopic sleeve is rotatably connected to one side of the threaded sleeve, and the other end of the telescopic sleeve is fixedly connected to the fixed plate.

[0011] Preferably, the material distribution rod is L-shaped, and there are three material distribution rods arranged in a circumferential array on the circumferential surface of the fixed rod. The material distribution rod is located inside the screen cylinder and is in contact with the inner wall of the screen cylinder. There are several push plates arranged in pairs inside the screen cylinder, and the material distribution rod is located between two push plates.

[0012] Preferably, the screening mechanism is provided with a vibration mechanism, which includes a spring. One end of the spring is fixedly connected to the inner wall of the base, and the other end of the spring is provided with a material box B. A sliding groove is opened on one side of the base, and a sliding rod is fixedly connected to one side of the material box B.

[0013] Preferably, the material box B is slidably connected to the inner wall of the base, the slide rod passes through the base through the slide groove and is slidably connected to the base, and the slide rod is located on the displacement trajectory of the push block.

[0014] Preferably, the end of the spring away from the inner wall of the base is engaged with one side of the material box B, and the material box B is located below the screen cylinder.

[0015] A method for using a gradeable battery crushed material separating screen includes the following steps: S1: When the equipment starts, the motor drives the rotating rod at the output shaft end to rotate, which in turn drives the fixedly connected gear A to rotate, thereby causing gear A to mesh with gear B and drive gear B to rotate around the fixed rod. The crushed battery material is fed into the feed port of the screen cylinder. As the screen cylinder rotates, the material continuously tumbles inside the cylinder. S2: The equipment is equipped with a clearing mechanism. A protrusion is fixed on the outer circumference of the screen cylinder. As the screen cylinder rotates, it periodically squeezes the force rod inside the device sleeve. The force rod is L-shaped and has a bevel at one end. After being squeezed, it slides along the inner wall of the device sleeve and compresses the spring telescopic rod through the short rod. When the protrusion rotates away, the spring telescopic rod pushes the force rod to return to its original position. S3: The material distribution mechanism performs a secondary material distribution operation. The material distribution rod, which is fixed on the fixed rod, remains stationary with the fixed rod. Its L-shaped structure and the design of the three circumferential arrays can move the material inside the screen cylinder and promote tumbling and screening. At the same time, the rotation of the screen cylinder drives the fixed plate inside it to rotate. The fixed plate drives the reciprocating screw to rotate, thereby causing the reciprocating screw to drive the threaded sleeve on it to reciprocate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the interplay between the force exerted by the protrusion pressing the force-bearing rod and components such as the device sleeve, spring telescopic rod, and short rod. When the screen cylinder rotates, it causes the screen cylinder to drive the protrusion in a circular motion, which in turn causes the protrusion to press against the inclined surface of the force-bearing rod. This forces the force-bearing rod, via the short rod, to move the push rod away from the screen cylinder. When the protrusion moves away from the force-bearing rod, the force-bearing rod, through the restoring property of the spring telescopic rod, causes the push rod to re-insert into the hole of the screen cylinder. This effectively unblocks the screen cylinder, preventing materials from getting stuck in the screen mesh or holes in the screen cylinder during screening, thus improving the smoothness of the screening process.

[0017] This invention utilizes the force of the rotating screen cylinder in conjunction with components such as the material distribution rod, reciprocating screw, and fixed plate. When the screen cylinder rotates, it causes the fixed plate to move in a circular motion, which in turn causes the reciprocating screw to rotate. This, in turn, causes the reciprocating screw to move the threaded sleeve horizontally, which in turn causes the push plate to move horizontally. This pushes larger materials that are difficult to screen to the baffle, and then, through the material pushing the baffle, the material slides down the inclined plate into material box A. This achieves the effect of simultaneously distributing materials that are difficult to screen in the screening mechanism, thus improving screening efficiency.

[0018] This invention utilizes the force of the rotating screen cylinder in conjunction with components such as springs and push blocks for material box B. When the screen cylinder rotates, it causes the push block to move in a circular motion, which in turn pushes a sliding rod, causing the sliding rod to move material box B away from the base. When the push block moves away from the sliding rod, material box B returns to the base through the spring's restoring action. This achieves the effect of vibrating material box B, preventing material from being screened and falling into the collection box, thus avoiding localized accumulation and improving both work efficiency and material discharge efficiency.

[0022] This invention provides a technical solution: such as Figure 1 - Figure 11The battery crushing material separating screen shown includes a screening mechanism 1.

[0023] The unblocking mechanism 2 also includes a protrusion 201, which is fixedly connected to the circumferential surface of the screen cylinder 108. A spring telescopic rod 203 is fixedly connected to the inner wall of the device sleeve 202. A force-bearing rod 204 is fixedly connected to one end of the spring telescopic rod 203 away from the inner wall of the device sleeve 202. A short rod 205 is fixedly connected to one side of the force-bearing rod 204. A torsion spring A206 is fixedly sleeved on the outer surface of the short rod 205. A push rod 207 passes through the end of the short rod 205 away from the force-bearing rod 204 and is rotatably connected to the push rod 207. The above design is conducive to unblocking the holes on the screen cylinder 108, preventing material blockage and affecting the screening efficiency.

[0024] One end of the torsion spring A206 is fixedly connected to the force-bearing rod 204, and the other end of the torsion spring A206 is fixedly connected to the push rod 207. The device sleeve 202 has an inclined surface on the side near the opening. The force-bearing rod 204 is L-shaped, with an inclined surface at one end. The end of the force-bearing rod 204 near the inclined surface is located on the displacement trajectory of the protrusion 201. The force-bearing rod 204 is slidably connected to the inner wall of the device sleeve 202. The screen cylinder 108 is located on the displacement trajectory of the push rod 207. The end of the push rod 207 near the screen cylinder 108 has an inclined surface. The above design is beneficial to push the push rod 207 away from the hole on the screen cylinder 108 by squeezing it with the protrusion 201.

[0025] The material distribution mechanism 3 also includes a material distribution rod 301, which is fixedly connected to the circumferential surface of the fixed rod 106. The end of the reciprocating screw 302 away from the fixed plate 303 is threadedly connected to a threaded sleeve 304. A push plate 305 is fixedly connected to one side of the threaded sleeve 304. A long rod 306 is rotatably connected to the end of the screen cylinder 108 near the gear B107. A torsion spring B307 is fixedly sleeved on the outer surface of the long rod 306. A baffle 308 is fixedly connected to the circumferential surface of the long rod 306. An inclined plate 309 is fixedly connected to the side of the base 101 near the base 102. A material box A310 is slidably connected to the inner wall of the base 102. A telescopic sleeve 311 is provided on the outer surface of the reciprocating screw 302. The above design is beneficial for screening larger materials that are difficult to screen in the screen cylinder 108.

[0026] One end of the torsion spring B307 is fixedly connected to the long rod 306, and the other end of the torsion spring B307 is fixedly connected to the baffle 308. The inclined plate 309 is located inside the base 102, below the baffle 308, and above the material box A310. One end of the telescopic sleeve 311 is rotatably connected to one side of the threaded sleeve 304, and the other end of the telescopic sleeve 311 is fixedly connected to the fixed plate 303. The above design is beneficial to protect the reciprocating screw 302 through the telescopic sleeve 311 and prevent the threads on the reciprocating screw 302 from being blocked by materials.

[0027] The material distribution rod 301 is L-shaped, and there are three material distribution rods 301 arranged in a circumferential array on the circumferential surface of the fixed rod 106. The material distribution rods 301 are located inside the screen cylinder 108 and are in contact with the inner wall of the screen cylinder 108. There are several push plates 305 arranged in pairs inside the screen cylinder 108. The material distribution rod 301 is located between two push plates 305. The above design is beneficial for intercepting larger materials through the material distribution rods 301, making it easier for the push plates 305 to push the materials.

[0028] The screening mechanism 1 is equipped with a vibration mechanism 4, which includes a spring 401. One end of the spring 401 is fixedly connected to the inner wall of the base 101, and the other end of the spring 401 is provided with a material box B402. A sliding groove 403 is opened on one side of the base 101, and a sliding rod 405 is fixedly connected to one side of the material box B402. A push block 404 is fixedly connected to the circumferential surface of the door 109. The above design is conducive to vibrating the material box B402 and preventing the material from piling up locally in the material box B402, which would affect the feeding efficiency.

[0029] Material box B402 is slidably connected to the inner wall of base 101. Slide rod 405 passes through base 101 through slide groove 403 and is slidably connected to base 101. Slide rod 405 is located on the displacement trajectory of push block 404. The above design is conducive to pushing slide rod 405 by push block 404, thereby causing slide rod 405 to drive material box B402 to move horizontally.

[0030] One end of the spring 401 away from the inner wall of the base 101 is engaged with one side of the material box B402, which is located below the screen cylinder 108. This design facilitates the disassembly of the material box B402 by engaging the spring 401 with the material box B402, so as to remove the material.

[0031] A method for using a gradeable battery crushed material separating screen includes the following steps: S1: When the equipment starts, the motor 103 drives the rotating rod 104 at the output shaft end to rotate, which in turn drives the fixedly connected gear A105 to rotate, thereby causing gear A105 to mesh with gear B107 for transmission, which in turn drives the screen cylinder 108 fixedly connected to it to rotate around the fixed rod 106. The crushed battery material is fed into the screen cylinder 108. As the screen cylinder 108 rotates, the material tumbles continuously inside the cylinder. S2: The equipment is equipped with a clearing mechanism 2. A protrusion 201 is fixed on the outer circumference of the screen cylinder 108. As the screen cylinder 108 rotates, it periodically squeezes the force rod 204 inside the device sleeve 202. The force rod 204 is L-shaped and has 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 rod 204 to reset. S3: The material distribution mechanism 3 performs a secondary material distribution operation. The material distribution rod 301, which is fixed on the fixed rod 106, remains stationary with the fixed rod 106. Its L-shaped structure and the design of the three circumferential arrays can move the material inside the screen cylinder 108 and promote tumbling and screening. At the same time, the rotation of the screen cylinder 108 drives the fixed plate 303 inside it to rotate. The fixed plate 303 drives the reciprocating screw 302 to rotate, thereby causing the reciprocating screw 302 to drive the threaded sleeve 304 on it to reciprocate.

[0032] Working principle: When the equipment starts, the motor 103 drives the rotating rod 104 at the output shaft end to rotate, which in turn drives the fixedly connected gear A105 to rotate. This causes gear A105 to mesh with gear B107, which in turn drives the screen cylinder 108, which is fixedly connected to it, to rotate around the fixed rod 106. The crushed battery material is fed into the screen cylinder 108 through the feed inlet. As the screen cylinder 108 rotates, the material tumbles continuously inside. Material smaller than the aperture of the screen cylinder 108 falls through the screen holes under the action of gravity and centrifugal force, achieving preliminary grading and screening. To improve screening efficiency and prevent clogging, the equipment is equipped with a clearing mechanism 2. A protrusion 201 is fixed on the outer circumference of the screen cylinder 108, which periodically squeezes the device sleeve 20 as the screen cylinder 108 rotates. The force-bearing rod 204 inside the device sleeve 202 is L-shaped with a beveled 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 reset. The torsion spring A206 sleeved on the short rod 205 ensures that the push rod 207 always tends to face the screen cylinder 108. The end of the push rod 207 is also designed with a bevel, which can be inserted into the hole of the screen cylinder 108 during reset to push the jammed material back into the cylinder, achieving dynamic unblocking and ensuring smooth screening. For large-sized materials that cannot pass through the screen cylinder 108, the material distribution mechanism 3 performs a secondary material distribution operation. The material distribution rod 301, fixed on the fixed rod 106, remains stationary with the fixed rod 106. Its L-shaped structure The design of the three circumferential arrays can agitate the material inside the screen cylinder 108, promoting tumbling and screening. Simultaneously, the rotation of the screen cylinder 108 drives the fixed plate 303 inside it to rotate. The fixed plate 303 drives the reciprocating screw 302 to rotate, causing the threaded sleeve 304 on the reciprocating screw 302 to reciprocate. This, in turn, drives the push plate 305 to push the large particles that cannot be screened out inside the screen cylinder 108 towards the baffle 308. After the material reaches the end of the screen cylinder 108, it pushes the baffle 308, which is fixed to the long rod 306. The baffle 308 opens due to the thrust overcoming the torque of the torsion spring B307, allowing the material to slide down the inclined plate 309 into the material box A310 inside the base 102 for collection, thus achieving automatic separation of unscreenable materials. Furthermore, the equipment also... The system integrates a vibration mechanism 4 to optimize the collection process. A pusher block 404 is fixed to the hinged door 109 of the screen cylinder 108. As the screen cylinder 108 rotates, the pusher block 405 periodically pushes the slide bar 405. The slide bar 405 is fixed to the material box B402, which is used to receive fine materials falling from the holes of the screen cylinder 108. When the slide bar 405 is pushed, it overcomes the elastic force of the spring 401, causing the material box B402 to move outward. After the pusher block 404 rotates away, the spring 401 pulls the material box B402 back to its original position quickly. This high-frequency vibration prevents fine materials from accumulating in the box, promotes the even distribution of materials, and improves collection efficiency and capacity. This separating screen achieves preliminary screening of materials through the rotation of the screen cylinder 108, and combines the anti-clogging mechanism 2, the material separating mechanism 3 to separate large particles, and the vibration mechanism 4 to optimize collection.This technology enables efficient and continuous grading and separation of battery fragments, improving overall work efficiency and reliability.

7. A method of using a gradeable battery crushed material separating screen, applied to the gradeable battery crushed material separating screen described in any one of claims 1-6, characterized in that: Includes the following steps: S1: When the equipment starts, 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 A (105) to rotate, and then the gear A (105) meshes with the gear B (107) to drive the screen cylinder (108) fixedly connected to it to rotate around the fixed rod (106). The battery crushed material is fed into the screen cylinder (108) from the feed port. As the screen cylinder (108) rotates, the material rolls continuously inside the cylinder. S2: The equipment is equipped with a dredging mechanism (2). A protrusion (201) is fixed on the outer circumference of the screen cylinder (108). As the screen cylinder (108) rotates, it periodically squeezes the force rod (204) inside the device sleeve (202). The force rod (204) is L-shaped and has 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 rod (204) to reset. S3: The material distribution mechanism (3) performs a secondary material distribution operation. The material distribution 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 circumferential arrays can move the material inside the screen cylinder (108) to promote tumbling and screening. At the same time, the screen cylinder (108) rotates and drives the fixed plate (303) inside it to rotate. 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).
