Description

Technical Field

[0001] The present invention belongs to the technical field of carbon anode product production, and particularly relates to a raw material crushing and screening device for carbon anode product production. Background Art

[0002] Carbon anode products refer to those mainly made of carbon and graphite materials. Carbon products can be classified into graphite electrode type, carbon block type, graphite anode, carbon fiber type, etc. according to product use. Carbon products are widely used in the carbon industry. When producing carbon products, the raw materials need to be crushed and screened, so crushing and screening devices are relatively common in production equipment;

[0003] Referring to a raw material crushing and screening device for carbon anode product production described in the patent application with reference number 201911212581.4, a raw material crushing and screening device for carbon anode product production includes a bracket, a motor, a first bevel gear, and a lead screw. An outer box body is welded and connected above the bracket, and a feed inlet is welded and connected above the outer box body. The motor is installed on the right side of the outer box body, and the output end of the motor is connected to a first rotating shaft. A first connecting gear is arranged on the outer wall of the first rotating shaft. A second connecting gear is meshed and connected behind the first connecting gear, and the second connecting gear is welded and connected to the outer wall of a second rotating shaft. The rear side of the second rotating shaft is connected to a third rotating shaft through a first transmission belt. Crushing teeth are arranged on the outer walls of the first rotating shaft and the third rotating shaft. By arranging the crushing teeth on the first rotating shaft and the third rotating shaft in a staggered manner, and the sum of the widths of the first rotating shaft, the third rotating shaft, and the crushing teeth is greater than the width of the feed inlet, when the raw materials enter, the raw materials can be extruded and crushed by the staggered crushing teeth, accelerating the crushing progress of the raw materials.

[0004] Sometimes in the production of carbon anode products, it is necessary to screen the crushed carbon and graphite to obtain raw material particles of the required particle size. Most of the existing carbon anodes are screened using a sieve mesh after crushing. As is well known, the shapes of solid carbon and graphite are different after crushing, showing a heterogeneous state with convex parts of different sizes. Since the inner diameter of the sieve holes is a fixed value, during the screening process, it is easy for the crushed carbon and graphite particles to be embedded in the sieve holes. Under the action of their own convex parts, these particle raw materials greatly increase the friction force with the inner wall of the sieve holes. The particle raw materials are in a dilemma in the sieve holes and cannot pass through the sieve holes, thus causing the sieve holes to be blocked. Since in order to improve the screening efficiency, most equipment is in a non-stop state, and the gradual blockage of a large number of sieve holes will reduce the screening efficiency. To solve the above problems, a steel bar cage welding device for bridge construction is provided. Summary of the Invention

[0005] The present invention provides a raw material crushing and screening device for the production of carbon anode products, aiming to solve the problem that the crushed carbon and graphite particles are embedded in the sieve holes. Under the action of their own convex parts, these particulate raw materials greatly increase the friction force with the inner wall of the sieve holes. The particulate raw materials are in a dilemma in the sieve holes and cannot pass through the sieve holes, thus causing the sieve holes to be blocked. Since in order to improve the screening efficiency, most of the equipment is in a non-stop state, and the gradual blockage of a large number of sieve holes will reduce the screening efficiency.

[0006] The present invention is realized as follows. A raw material crushing and screening device for the production of carbon anode products includes a base plate: A support power assembly and a crushing assembly are fixedly connected to the top of the base plate. The support power assembly is located on one side of the crushing assembly, and a grading and screening assembly is supported above the support power assembly;

[0007] Among them, the grading and screening assembly includes a screening rotating cylinder, and an anti-blocking and dredging assembly is arranged on the outer side wall of the screening rotating cylinder;

[0008] The anti-blocking and dredging assembly includes a rotating toothed ring and a rotating support ring. Both the rotating toothed ring and the rotating support ring are embedded in an annular groove on the outer side wall of the screening rotating cylinder and are slidably connected to each other.

[0009] Preferably, a cross plate is fixedly connected between the rotating toothed ring and the rotating support ring. An electric push rod is fixedly connected to the outer wall of the cross plate on the side far from the screening rotating cylinder. The electric push rod is fixedly connected to a moving plate through an output end on one side of it. Pushing columns are welded at equal intervals on the outer wall of the moving plate on the side far from the output end of the electric push rod;

[0010] Among them, the rotating toothed ring is located on one side of the rotating support ring and is horizontal with each other. A total of four cross plates are provided, and the four cross plates are arranged at equal intervals within a range of 60 degrees in the 360-degree axial direction.

[0011] Preferably, the anti-blockage and dredging component further includes a fixing frame fixedly connected to the top of the substrate base. A three-phase motor is fixedly connected to the outer wall of one side of the fixing frame. A rotary gear is fixedly connected to the output end of one side of the three-phase motor. The rotary gear and the rotary toothed ring are connected by meshing of teeth. By starting and controlling the use of the three-phase motor, the three-phase motor drives the rotary gear to rotate through the output end of one side thereof. By means of the meshing transmission between the rotary gear and the rotary toothed ring, the rotary toothed ring rotates axially on the screening drum. Since the rotary toothed ring and the rotary support ring are connected and supported by a cross plate, through the sliding of the rotary support ring on the screening drum, the cross plate makes a circular motion around the screening drum. By controlling the rotation speed of the three-phase motor and the transmission ratio between the rotary gear and the rotary toothed ring, the relative position between the cross plate and the screening drum is controlled. On the one hand, it is ensured that the screening drum and the cross plate rotate in a relatively static state, so as to facilitate the use of the electric push rod on the cross plate to drive the moving plate to move towards the screening drum through the output end of one side thereof. The pushing column on the moving plate is inserted into the sieve holes on the screening drum to eject the blocked carbon anode raw materials in the sieve holes and achieve the blockage removal of the sieve holes. On the other hand, when it is ensured that the screening drum is still in a rotating state, the cross plate can be controlled to rotate and reset to the initial position at a relatively several times the rotation speed, and it is ensured that the cross plate and the screening drum rotate in a relatively static state again, so as to clean the sieve holes on the screening drum in turn and prevent the sieve holes from being blocked.

[0012] Preferably, the support power component includes an I-shaped support wheel bracket fixed to the top of the substrate base. An I-shaped support wheel is rotatably connected to the inner side wall of the I-shaped support wheel bracket. A driving gear bracket is fixedly connected to the top of the substrate base at a position close to one side of the I-shaped support wheel bracket. A driving gear is rotatably connected to the inner side wall of the driving gear bracket. The driving gear is driven by an external servo motor.

[0013] A driven toothed ring and a guide ring are fixedly connected to the outer side wall of the screening drum. The driven toothed ring is located on one side of the guide ring.

[0014] The driving gear and the driven toothed ring are connected by meshing of teeth. The outer side wall of the guide ring matches the inner side wall of the I-shaped support wheel. The I-shaped support wheel provides guiding support for the guide ring. By providing support for the guide ring by the I-shaped support wheel, the screening drum can rotate in the air, realizing the stable rotation of the screening drum, which is beneficial to the screening of carbon anode raw materials. Through the meshing transmission between the driving gear and the driven toothed ring, by controlling and using the external servo motor to drive, after the driving gear rotates, it drives the driven toothed ring to rotate. Since the driven toothed ring and the screening drum are in a fixed connection state, the screening drum rotates synchronously, and the uniform rotation of the screening drum is controlled.

[0015] Preferably, a rotary drum cover is hinged to the open end of the screening rotary drum. A handle is fixedly connected to the outer wall of the rotary drum cover on the side far from the screening rotary drum. Two types of sieve holes with different inner diameters are formed in the outer wall of the screening rotary drum. An inlet rotary sleeve is rotatably connected through the outer wall of the screening rotary drum on the side far from the rotary drum cover.

[0016] The two sieve holes with different inner diameters are arranged at a certain interval. A plurality of sieve holes are provided and are axially arranged at equal intervals on the outer wall of the screening rotary drum. The carbon anode raw material particles in the screening rotary drum can be screened from small to large in turn by using the sieve holes with different inner diameters, realizing the classification screening of the carbon anode raw materials, ensuring the screening efficiency and facilitating the subsequent re-crushing of the larger carbon anode raw material particles to obtain smaller carbon anode raw material particles. After opening the rotary drum cover by holding the handle, the large carbon anode raw material particles that cannot be screened out and are gathered at the inner end of the screening rotary drum are taken out, facilitating the subsequent re-crushing processing.

[0017] Preferably, the crushing assembly includes four support legs symmetrically and fixedly connected to the top of the base plate near the grading and screening assembly. A crushing box is fixedly connected between the four support legs. A feed hopper is welded to the top of the crushing box. A first crushing roller and a second crushing roller are rotatably connected to the inner wall of the crushing box. The first crushing roller is located on the horizontal side of the second crushing roller. A discharge pipe is arranged at the bottom of the crushing box.

[0018] The discharge pipe is communicated with the inlet rotary sleeve and is rotatably connected to the inlet rotary sleeve. The outer walls of the first crushing roller and the second crushing roller are provided with matching crushing teeth. The first crushing roller is driven by an external reduction motor. The first crushing roller and the second crushing roller are driven by an external gear set in meshing. By controlling and using the external reduction motor, after the external reduction motor drives the first crushing roller to rotate, the second crushing roller is driven to rotate by the external gear set in meshing. The first crushing roller and the second crushing roller rotate towards each other. After the crushing teeth on the first crushing roller and the second crushing roller are engaged, the carbon anode raw material above is crushed. The crushed carbon anode raw material sequentially passes through the discharge pipe and the inlet rotary sleeve and enters the screening rotary drum.

[0019] Preferably, an anti-spillage component is arranged outside the screening rotary drum. The anti-spillage component includes a support plate fixed to the top of the base plate. A protective plate is fixedly connected to the top of the support plate.

[0020] The cross-section of the protective plate is arc-shaped, and the protective plate is closely attached to the outer side wall of the screening rotating cylinder. There are four protective plates in total, and every two of the four protective plates are symmetrically arranged on the outer side of the screening rotating cylinder. The top and bottom of the screening rotating cylinder lack the protection of the protective plate, so that the sieve holes are exposed. By tightly attaching the protective plate to the outer side of the screening rotating cylinder, it is possible to prevent the carbon anodic raw materials from leaking out of the sieve holes during the rotation of the screening rotating cylinder, thereby avoiding the chaos of the feeding positions of the carbon anodic raw materials. Under the protection of the protective plate, the top and bottom of the screening rotating cylinder are exposed, which not only provides space for clearing the blockage of the sieve holes, but also limits the feeding position of the carbon anodic raw materials after screening, thus facilitating subsequent collection.

[0021] Preferably, the positions of the pushing columns and the sieve holes correspond one by one on the axial trajectories of the same axis but different radii, and the pushing columns can pass through the sieve holes. The thrust generated by inserting the pushing columns through the sieve holes can push out the carbon anodic raw materials blocked in the sieve holes, avoiding the blockage of the sieve holes. The one-to-one position state also prevents the movement interference between the pushing columns and the outer side wall of the screening rotating cylinder.

[0022] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0023] Through the setting of the anti-blocking and dredging component, the relative position between the cross plate and the screening rotating cylinder in the rotating state can be controlled. On the one hand, it is ensured that when the cross plate moves axially, it has the same rotational speed as the screening rotating cylinder, so that the screening rotating cylinder and the cross plate are in a relatively static rotational state, which is convenient for the pushing columns to be inserted into the sieve holes on the screening rotating cylinder when the moving plate moves towards the screening rotating cylinder, realizing the ejection of the carbon anodic raw materials blocked in the sieve holes and clearing the blockage of the sieve holes, avoiding the problem of sieve hole blockage caused by the carbon anodic raw materials being unable to pass through the sieve holes under the action of their own convex parts, ensuring the smoothness of the sieve holes, and thus ensuring the screening efficiency. On the other hand, when the screening rotating cylinder is in a rotating state, it is ensured that the cross plate can rotate back to the initial position at a relatively several times the rotational speed and ensure that the cross plate and the screening rotating cylinder are in a relatively static rotational state again, so as to clean the sieve holes on the screening rotating cylinder in turn, realizing the cleaning of the sieve holes under the condition that the device does not stop, and further improving the screening efficiency.

[0024] Through the settings of the grading and screening component and the anti-leakage component, the carbon anode raw material particles in the screening rotating cylinder can be screened from small to large by using sieve holes with different inner diameters, realizing the grading and screening of the carbon anode raw materials. While ensuring the screening efficiency, it is also convenient to further crush the larger carbon anode raw material particles for subsequent processing to obtain smaller carbon anode raw material particles. By attaching the protective plate tightly to the outside of the screening rotating cylinder, it can prevent the carbon anode raw materials from leaking out of the sieve holes during the rotation of the screening rotating cylinder, thus avoiding the chaos of the feeding position of the carbon anode raw materials. Under the protection of the protective plate, the top and bottom of the screening rotating cylinder are exposed, which not only provides space for cleaning and unblocking the sieve holes but also limits the feeding position of the carbon anode raw materials after screening, thus facilitating subsequent collection.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0036] An embodiment of the present invention provides a raw material crushing and screening device for the production of carbon anodic products, including a substrate base 1. A support power assembly 2 and a crushing assembly 5 are fixedly connected to the top of the substrate base 1. The support power assembly 2 is located on one side of the crushing assembly 5, and a grading and screening assembly 3 is supported above the support power assembly 2;

[0037] Among them, the grading and screening assembly 3 includes a screening drum 301, and an anti-blockage and dredging assembly 4 is arranged on the outer side wall of the screening drum 301;

[0038] The anti-blocking and dredging component 4 includes a rotary gear ring 404 and a rotary support ring 405. Both the rotary gear ring 404 and the rotary support ring 405 are embedded in the annular groove on the outer side wall of the screening rotary drum 301 and are slidably connected to each other.

[0039] A cross plate 406 is fixedly connected between the rotary gear ring 404 and the rotary support ring 405. On the outer wall of the cross plate 406 away from the screening rotary drum 301, an electric push rod 407 is fixedly connected. The electric push rod 407 is fixedly connected to a moving plate 408 through its output end on one side. On the outer wall of the moving plate 408 away from the output end of the electric push rod 407, pushing columns 409 are welded at equal intervals;

[0040] Among them, the rotary gear ring 404 is located on one side of the rotary support ring 405 and is horizontal with each other. There are four cross plates 406 in total, and the four cross plates 406 are arranged at equal intervals within a range of 60 degrees in the 360-degree axial direction.

[0041] The anti-blocking and dredging component 4 further includes a fixing frame 401 fixedly connected to the top of the base plate 1. On the outer wall of one side of the fixing frame 401, a three-phase motor 402 is fixedly connected. The three-phase motor 402 is fixedly connected to a rotary gear 403 through its output end on one side;

[0042] The rotary gear 403 and the rotary gear ring 404 are connected by gear meshing.

[0043] The support power component 2 includes an I-shaped support wheel bracket 201 fixed to the top of the base plate 1. An I-shaped support wheel 202 is rotatably connected to the inner side wall of the I-shaped support wheel bracket 201. At a position on the top of the base plate 1 close to the I-shaped support wheel bracket 201, a driving gear bracket 203 is fixedly connected. A driving gear 204 is rotatably connected to the inner side wall of the driving gear bracket 203, and the driving gear 204 is driven by an external servo motor;

[0044] A driven gear ring 302 and a guide ring 303 are fixedly connected to the outer side wall of the screening rotary drum 301. The driven gear ring 302 is located on one side of the guide ring 303;

[0045] The driving gear 204 and the driven gear ring 302 are connected by gear meshing. The outer side wall of the guide ring 303 matches the inner side wall of the I-shaped support wheel 202, and the I-shaped support wheel 202 provides guiding support for the guide ring 303.

[0046] The open end of the screening rotary drum 301 is hinged with a rotary drum cover 304. A handle 305 is fixedly connected to the outer wall of the rotary drum cover 304 away from the screening rotary drum 301. Two kinds of sieve holes 306 with different inner diameters are opened on the outer side wall of the screening rotary drum 301, and a feed rotary sleeve 307 is rotatably connected through the outer side wall of the screening rotary drum 301 away from the rotary drum cover 304;

[0047] The sieve holes 306 with two different inner diameters are arranged at a certain interval. There are several sieve holes 306, and they are arranged at equal axial intervals on the outer side wall of the screening rotary drum 301. At the position on the inner side wall of the screening rotary drum 301 that is offset from the sieve holes 306, a flake plate for turning the carbon anode raw material can be installed, so that the carbon anode raw material is turned in the rotating screening rotary drum 301, facilitating the carbon anode raw material to pass through the sieve holes 306.

[0048] It should be noted that since the shapes of solid carbon and graphite are different after being broken, they will be in a deformed state with convex parts of different sizes. Since the inner diameter of the sieve hole is a fixed value, during the screening process, it is easy for the broken carbon and graphite particles to be embedded in the sieve hole. Under the action of their own convex parts, these particulate raw materials greatly increase the friction force with the inner wall of the sieve hole. The particulate raw materials are in a dilemma in the sieve hole and cannot pass through the sieve hole, thus causing the sieve hole to be blocked. Since in order to improve the screening efficiency, most of the equipment is in a non-stop state, and the gradual blockage of a large number of sieve holes will reduce the screening efficiency. To solve the above problems, a steel cage welding device for bridge construction is provided.

[0049] Specifically, in this embodiment, this solution mainly uses the cooperation of the support power assembly 2, the grading screening assembly 3, and the anti-blocking and dredging assembly 4. When in use, first, the base plate base 1 is placed stably. Of course, the base plate base 1 can also be placed and fixed in a state where one side is low and the other side is high. Through the support of the I-shaped support wheels 202 on the support power assembly 2 for the guide ring 303, the screening rotary drum 301 in the grading screening assembly 3 is supported by the four symmetrically arranged I-shaped support wheels 202. When controlling the rotation of the driving gear 204, by the meshing between the driving gear 204 and the driven gear ring 302, first, the screening rotary drum 301 rotates, and the screening rotary drum 301 rotates in a horizontal state or an inclined state. The broken carbon anode raw material tumbles in the screening rotary drum 301;

[0050] The carbon anode raw material particles that can pass through the sieve holes 306 pass through the sieve holes 306, and the larger particle carbon anode raw materials are still inside the screening rotary drum 301. As the screening rotary drum 301 continues to rotate, the carbon anode raw material is turned and falls, so as to improve the screening efficiency of the carbon anode raw material. When the carbon anode raw material is screened by the sieve holes 306 with two different inner diameters twice, the un-screened carbon anode raw material accumulates in the screening rotary drum 301. At this time, the rotary drum cover 304 can be opened by holding the handle 305, and the un-screened carbon anode raw material can be taken out for subsequent re-crushing processing;

[0051] When the sieve holes 306 are blocked by carbon anode raw material particles, by starting and controlling the use of a three-phase motor 402, the three-phase motor 402 drives the rotary gear 403 to rotate through the output end on one side thereof. By means of the meshing drive between the rotary gear 403 and the rotary gear ring 404, the rotary gear ring 404 rotates axially on the screening drum 301. Since the rotary gear ring 404 and the rotary support ring 405 are connected and supported by a cross plate 406, through the sliding of the rotary support ring 405 on the screening drum 301, the cross plate 406 makes a circular motion around the screening drum 301. By controlling the rotation speed of the three-phase motor 402 and the transmission ratio between the rotary gear 403 and the rotary gear ring 404, the relative position between the cross plate 406 and the screening drum 301 is controlled. On the one hand, it is ensured that the screening drum 301 and the cross plate 406 are in a relatively stationary rotating state, so as to facilitate the use of the electric push rod 407 on the cross plate 406 to drive the moving plate 408 to move towards the screening drum 301 through the output end on one side thereof. The pushing column 409 on the moving plate 408 is inserted into the sieve holes 306 on the screening drum 301, so as to eject the blocked carbon anode raw materials in the sieve holes 306 and realize the blockage removal of the sieve holes 306. On the other hand, when it is ensured that the screening drum 301 is still in a rotating state, it is possible to control the cross plate 406 to rotate and reset to the initial position at a relatively several-fold rotation speed, and ensure that the cross plate 406 and the screening drum 301 are again in a relatively stationary rotating state. Thus, when the cross plate 406 and the screening drum 301 move axially synchronously, the pushing column 409 can be gradually inserted into the sieve holes 306 again, so as to clean the sieve holes 306 on the screening drum 301 in turn and prevent the sieve holes 306 from being blocked;

[0052] In this embodiment, through the setting of the support power assembly 2, during use, after the I-shaped support wheel bracket 201 and the driving gear bracket 203 are respectively fixedly installed on the base plate 1, and the I-shaped support wheels 202 on the I-shaped support wheel bracket 201 are symmetrically arranged below the grading and screening assembly 3, a part of the guide ring 303 in the grading and screening assembly 3 is embedded in the inner side of the I-shaped support wheels 202. The I-shaped support wheels 202 provide stable support for the grading and screening assembly 3 and ensure the rotation of the screening drum 301 in the grading and screening assembly 3. By the cooperation of the I-shaped support wheels 202 and the guide ring 303, while ensuring the stable rotation of the screening drum 301, the frictional resistance is reduced, thereby reducing energy consumption. The driving gear 204 meshes with the driven gear ring 302 in the grading and screening assembly 3, and kinetic energy is transmitted through the meshing drive, so as to realize the rotation of the screening drum 301. By the rotation of the screening drum 301, the purpose of rolling and screening the crushed carbon anode raw materials is achieved;

[0053] In this embodiment, through the setting of the grading and screening component 3, during use, as the screening drum 301 rotates, the carbon anode raw materials are turned under the action of the flaky plates on the inner side wall of the screening drum 301. The carbon anode raw materials are turned from the bottom to a high place and then fall, which facilitates the separation of carbon anode raw materials of different particle sizes for efficient screening of the carbon anode raw materials. Since there are two types of sieve holes 306 with different inner diameters on the screening drum 301, the carbon anode raw material particles in the screening drum 301 can be screened from small to large in sequence using the sieve holes 306 with different inner diameters, realizing the grading and screening of the carbon anode raw materials. While ensuring the screening efficiency, it is also convenient to further crush the larger particle carbon anode raw materials subsequently to obtain carbon anode raw materials with smaller particles. After opening the drum cover 304 by holding the handle 305, the large particle carbon anode raw materials that cannot be screened out and accumulate at the inner end of the screening drum 301 are taken out, facilitating subsequent re-crushing processing;

[0054] In this embodiment, through the setting of the anti-blocking and dredging component 4, during use, the rotation speed of the three-phase motor 402, as well as the transmission ratio of the rotary gear 403 and the rotary ring gear 404, are controlled to control the relative position of the cross plate 406 and the screening drum 301, ensuring that the screening drum 301 and the cross plate 406 rotate in a relatively stationary state. Furthermore, it is convenient to use the electric push rod 407 on the cross plate 406 to drive the moving plate 408 to move towards the screening drum 301 through the output end on one side. The pushing column 409 on the moving plate 408 is inserted into the sieve hole 306 on the screening drum 301 to eject the carbon anode raw materials blocked in the sieve hole 306, realizing the cleaning of the sieve hole 306. When ensuring that the screening drum 301 is still in a rotating state, the cross plate 406 can be controlled to rotate and reset to the initial position at a relatively several times the speed, and it is ensured that the cross plate 406 and the screening drum 301 rotate in a relatively stationary state again. Furthermore, when ensuring that the cross plate 406 and the screening drum 301 move axially synchronously, the pushing column 409 can be inserted into the sieve hole 306 step by step again, thereby cleaning the sieve holes 306 on the screening drum 301 in turn to prevent the sieve holes 306 from being blocked.

[0055] In a further preferred embodiment of the present invention, the crushing component 5 includes four support legs 501 symmetrically and fixedly connected to the top of the substrate base 1 near one side of the grading and screening component 3. A crushing box 502 is fixedly connected between the four support legs 501. A feed hopper 503 is welded to the top of the crushing box 502, and a first crushing roller 504 and a second crushing roller 505 are rotatably connected to the inner side wall of the crushing box 502. The first crushing roller 504 is located horizontally on one side of the second crushing roller 505. A discharge pipe 506 is provided at the bottom of the crushing box 502;

[0056] The discharge pipe 506 is communicated with the feed rotating sleeve 307, and the discharge pipe 506 and the feed rotating sleeve 307 are rotatably connected.

[0057] A leakage prevention component 6 is arranged on the outer side of the screening rotary drum 301. The leakage prevention component 6 includes a support plate 601 fixed to the top of the base plate base 1, and a protection plate 602 is fixedly connected to the top of the support plate 601;

[0058] The cross-section of the protection plate 602 is arc-shaped, and the protection plate 602 is closely attached to the outer side wall of the screening rotary drum 301.

[0059] The positions of the pushing columns 409 and the sieve holes 306 correspond one by one on the axial trajectories of the same axis but different radii, and the pushing columns 409 can pass through the sieve holes 306.

[0060] A total of four protection plates 602 are provided, and every two of the four protection plates 602 are symmetrically arranged on the outer side of the screening rotary drum 301. The top and bottom of the screening rotary drum 301 lack the protection of the protection plates 602, so that the sieve holes 306 are exposed.

[0061] Engaging crushing teeth are arranged on the outer side walls of the first crushing roller 504 and the second crushing roller 505. The first crushing roller 504 is driven by an external reduction motor, and the first crushing roller 504 and the second crushing roller 505 are driven by an externally meshing gear set.

[0062] In this embodiment, through the setting of the crushing component 5, during use, the external reduction motor is controlled and used. After the external reduction motor drives the first crushing roller 504 to rotate, the second crushing roller 505 is driven to rotate by the externally meshing gear set. The first crushing roller 504 and the second crushing roller 505 rotate towards each other. After the crushing teeth on the first crushing roller 504 and the second crushing roller 505 are engaged, the carbon anode raw materials above are crushed. The crushed carbon anode raw materials sequentially pass through the feeding pipe 506 and the feeding rotating sleeve 307 and enter the screening rotary drum 301;

[0063] In this embodiment, through the setting of the leakage prevention component 6, by closely attaching the protection plate 602 to the outer side of the screening rotary drum 301, it is possible to prevent the carbon anode raw materials from leaking out of the sieve holes 306 during the rotation of the screening rotary drum 301, thereby causing chaos in the feeding position of the carbon anode raw materials. Under the protection of the protection plate 602, the top and bottom of the screening rotary drum 301 are exposed, which not only provides space for clearing the blockage of the sieve holes 306, but also limits the feeding position of the carbon anode raw materials after screening, thereby facilitating subsequent collection.
