Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, in particular to a feeding device for mud pellet production. Background Art

[0002] The cold-pressed red mud pellet production line mainly consists of a three-bin batching machine, a conveyor, a forced mixer, a belt conveyor and a ball press. Red mud, mineral powder and additives are weighed and measured by the three-bin feeder, and then sent to the forced mixer via a conveyor. At the same time, the binder is added to the forced mixer. The forced mixer stirs multiple materials to form a mixture. The mixture falls from the discharge port of the forced mixer into the hopper of the belt conveyor, and then falls from the hopper to the conveyor belt of the belt conveyor. The reduction motor drives the conveyor belt through the conveyor roller to realize the transportation of the mixture, and then the mixture is transported to the ball press. The ball press cold-presses the loose mixture into pellets. The belt conveyor is the feeding equipment for mud pellet production.

[0003] In a common cold-pressed red mud pellet production line, the working process of the feeder is that the mixture formed by the forced mixer first falls into the hopper of the belt conveyor, and then falls from the hopper to the conveyor belt of the belt conveyor. Finally, the belt conveyor transports the mixture to the pelletizing machine and presses it into balls. However, since a binder is used in the production process of red mud pellets, when the mixture falls into the hopper and then falls from the hopper to the conveyor belt again, the mixture in the hopper is easy to stick to each other. This bonding phenomenon will cause the mixture to accumulate in the hopper, which can easily cause blockage inside the hopper, and ultimately affect the normal transportation of the mixture by the belt conveyor. Therefore, the present application provides a feeding equipment for mud pellet production to meet the needs. Summary of the Invention

During operation, the reduction motor drives the first sieve drum and the second sieve drum to rotate through the rotating shaft, thereby realizing screening of the mixed material, and the agglomerated materials screened out of the mixed material are accumulated at the connection position of the first sieve drum and the second sieve drum.

[0010] Preferably, a row of spring pieces 1 is fixed on one side of the sealing plate close to the reduction motor, and a breaking plate is fixed to the bottom of the spring piece 1, which is located inside the second screen drum. During the rotation of the first screen drum and the second screen drum, several long strips of paddles are driven to squeeze the breaking plate in turn, so that the spring piece 1 is deformed and rebounds under the force, thereby generating vibration, thereby breaking up the agglomerated materials accumulated at the connection position of the first screen drum and the second screen drum.

[0014] Preferably, a plurality of raised portions are provided on the top of the protective plate, and the raised portions are in an inverted V shape.

[0015] Preferably, a plurality of long through grooves are provided on the side surface of the scattering plate.

[0016] Preferably, several of the long shift plates are commonly connected with a retaining ring, which is trumpet-shaped, and the larger end of the retaining ring is facing the side away from the sealing plate. Several crushing blocks are fixed on the side of the retaining ring close to the sealing plate. The crushing blocks are triangular in shape, and the acute-angled ends of the crushing blocks are facing the scattering plate.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] The up and down movement and deformation of the main elastic bar, auxiliary elastic bar and small elastic bar on the anti-blocking head greatly improves the anti-blocking ability inside the hopper, ensures that the mixed material falls stably onto the conveyor belt of the belt conveyor, thereby ensuring stable transportation of the mixed material by the belt conveyor.

[0019] Through the arrangement of the first screen drum, the second screen drum and the long strip paddle, the opening of the first screen drum gradually becomes smaller, the mixture enters from the small opening end and gradually moves to the large opening end, which can prevent the mixture from accumulating in the first screen drum. The long strip paddle rotates with the first screen drum, lifting the mixture and making it fall from a height, and using the force of the fall to initially disperse the agglomerated materials. At the same time, affected by the shape of the first screen drum, the height of the mixture lifted up gradually increases, and the impact force gradually becomes stronger, further improving the dispersion effect. Afterwards, the loose mixture falls to the belt conveyor, and the agglomerated materials are accumulated at the connection between the first screen drum and the second screen drum with gradually larger openings, ensuring that the mixture on the belt conveyor is uniform and free of agglomerates, thereby ensuring the production quality of red mud pellets.

[0020] Through the arrangement of the spring piece 1 and the breaking up plate, when the first screen drum and the second screen drum rotate, the multiple long strip plates squeeze the breaking up plate in turn, causing the spring piece 1 to deform and rebound under force, thereby generating vibration. The spring piece 1 drives the breaking up plate to vibrate. During the vibration process, the breaking up plate breaks up the agglomerated materials it contacts, restores the agglomerated materials to a loose state, and enables them to pass through the second screen drum and fall onto the belt conveyor.

[0021] Through the setting of the retaining ring and the crushing block, part of the agglomerated materials brought up by the vibration of the scattering plate hits the retaining ring to be crushed and dispersed. At the same time, the crushing block is used to further crush the agglomerated materials, thereby further improving the dispersion effect of the agglomerated materials.

[0022] By setting the inclined portion 2, the lengths of several circumferentially distributed inclined portions 2 increase successively, and the inclined portions 2 with successively increasing lengths pass through the position of the breaking up plate successively during the rotation process. Affected by the different lengths of several inclined portions 2, the vibration frequency of the breaking up plate can be changed. A breaking up plate with small amplitude but high vibration frequency can effectively break up smaller agglomerated materials, and a breaking up plate with large amplitude but low vibration frequency can effectively break up larger agglomerated materials, thereby adapting to the breakup of agglomerated materials of different sizes.

[0023] By setting the protective plate and the fan-shaped limiting plate, the protective plate is fixed to the side of the blocking plate to prevent the agglomerated material falling from above from falling on the shrapnel 1 and affecting the vibration of the shrapnel 1. At the same time, the fan-shaped limiting plate is slidably connected to the side of the protective plate to prevent the second screen drum from driving the agglomerated material to roll inside it and causing the shrapnel 1 on the breaking up plate to twist, thereby ensuring the stable vibration of the shrapnel 1. The cutting surface set on the top of the fan-shaped limiting plate can cut the agglomerated material with its sharp edge when it comes into contact with the agglomerated material falling from above, and assist the breaking up plate to crush the agglomerated material, thereby further improving the processing effect of the agglomerated material.

DETAILED DESCRIPTION

[0041] The following describes in detail a feeding device for producing mud pellets provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0042] In general, terms can be understood, at least in part, from their use in context. For example, depending at least in part on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending at least in part on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0043] like Figures 1-13As shown, an embodiment of the present invention provides a feeding device for mud pellet production, comprising a belt conveyor 1. A reduction motor 3 is fixed to the frame of the belt conveyor 1 via a bracket. A rotating shaft 9 is fixed to the end of the output shaft of the reduction motor 3. A housing 2 is fixed to the frame of the belt conveyor 1 via a support rod. A blocking plate 4 is fixed to the side of the housing 2 away from the reduction motor 3. A hopper 5 is embedded on the side of the housing 2 close to the reduction motor 3. An anti-blocking mechanism 26 is provided in the hopper 5. A bulking mechanism 6 is provided in the housing 2. The above structure constitutes the feeding device for mud pellet production, which feeds the pelletizing machine to realize the conveyance of the mixed material (composed of red mud, mineral powder and binder);

[0044] The anti-blocking mechanism 26 includes a driving component 27 and an anti-blocking head 31. The driving component 27 is arranged on the rotating shaft 9. When the reduction motor 3 is running, the anti-blocking head 31 is driven up and down by the driving component 27. The anti-blocking head 31 includes a vertical rod 32 arranged in the hopper 5. A plurality of main elastic bars 33 are fixed on the top of the vertical rod 32. The main elastic bars 33 are arc-shaped. There are four main elastic bars 33. The four main elastic bars 33 are distributed in a circular array with the center of the vertical rod 32 as the center of the array. A wear-resistant sleeve 37 is fixed to the circumferential surface of the main elastic bar 33. A plurality of first wear-resistant blocks 38 and a plurality of second wear-resistant blocks 39 are fixed to the inner wall of the hopper 5 respectively. The first wear-resistant block 38 is slidably connected to the outer wall of the wear-resistant sleeve 37. The design of the wear-resistant sleeve 37 and the first wear-resistant block 38 is used to improve the main elastic bar 33. The wear resistance between the main spring bar 33 and the inner wall of the hopper 5 is improved, thereby improving the service life of the main spring bar 33 and the hopper 5. When the main spring bar 33 moves up and down following the vertical rod 32, when the main spring bar 33 moves downward, the first wear-resistant block 38 squeezes the wear-resistant sleeve 37, so that the main spring bar 33 moves downward and simultaneously bends inwardly. When the main spring bar 33 moves upward, the squeezing force of the first wear-resistant block 38 on the wear-resistant sleeve 37 gradually decreases, so that the main spring bar 33 moves upward and simultaneously expands outwardly. The movement of the main spring bar 33 is used to effectively prevent the inner wall of the hopper 5 from being blocked away from the corner. An auxiliary spring bar 34 is fixed between two adjacent main spring bars 33. The auxiliary spring bar 34 is used to increase the elastic force of the main spring bar 33, thereby effectively reducing the elastic fatigue of the main spring bar 33, further The service life of the main elastic bar 33 is improved in this step, and the auxiliary elastic bar 34 moves with the main elastic bar 33. When the auxiliary elastic bar 34 moves, it is affected by the deformation of the main elastic bar 33, and the auxiliary elastic bar 34 is deformed synchronously, thereby improving the anti-blocking ability of the corner of the inner wall of the hopper 5. The auxiliary elastic bar 34 is in an inverted V shape, and a pull bar 35 is passed through the bending part of the auxiliary elastic bar 34. A small elastic bar 36 is fixed at one end of the pull bar 35 away from the vertical rod 32. The end of the small elastic bar 36 away from the pull bar 35 is slidably connected to the surface of the second wear-resistant block 39, and the small elastic bar 36 moves up and down with the auxiliary elastic bar 34. When the small elastic bar 36 moves downward, its end moves along the inclined surface on the second wear-resistant block 39 and is squeezed by the inclined surface, so that the small elastic bar 36 moves downward and simultaneously bends inward. When the end of 36 moves to the vertical surface on the second wear-resistant block 39, the small elastic bar 36 stops deforming. When the auxiliary elastic bar 34 drives the small elastic bar 36 to move upward through the shift bar 35, when the end of the small elastic bar 36 separates from the vertical surface on the second wear-resistant block 39 and fits into the inclined surface on the second wear-resistant block 39, the small elastic bar 36 bends outward while moving upward. The design of the shift bar 35 and the small elastic bar 36 further improves the anti-blocking ability of the auxiliary elastic bar 34 at the corner of the inner wall of the hopper 5, thereby effectively preventing blockage inside the hopper 5 and ensuring that the mixture falls smoothly onto the conveyor belt of the belt conveyor 1, thereby realizing stable transportation of the mixture by the belt conveyor 1, and the elastic forces of the main elastic bar 33, the auxiliary elastic bar 34 and the small elastic bar 36 decrease successively.

[0045] like Figure 2-Figure 4 As shown, in this embodiment, the driving assembly 27 includes an eccentric disk 28 sleeved on the rotating shaft 9, a guide plate 30 is fixed to the side of the housing 2, and a square ring 29 is slidably connected to the side of the guide plate 30. The inner wall of the square ring 29 is rotatably connected to the circumferential surface of the eccentric disk 28, and a vertical rod 32 is fixed to the top of the square ring 29. The inner wall of the hopper 5 is fixed with a guide sleeve through an oblique bar. The vertical rod 32 is slidably connected to the inner wall of the guide sleeve. When the rotating shaft 9 rotates slowly under the drive of the reduction motor 3, the rotating shaft 9 drives the eccentric disk 28 to slowly rotate. During the slow rotation of the eccentric disk 28, the eccentric disk 28 alternately squeezes the top and bottom of the inner wall of the square ring 29. When squeezing the top of the inner wall of the square ring 29, the square ring 29 moves upward along the side of the guide plate 30 and drives the vertical rod 32 to move upward. When squeezing the bottom of the inner wall of the square ring 29, the square ring 29 moves downward along the side of the guide plate 30 and drives the vertical rod 32 to move downward. By alternately squeezing the square ring 29 by the eccentric disk 28, the square ring 29 can drive the vertical rod 32 to reciprocate up and down.

[0046] like Figure 6-Figure 7As shown, in this embodiment, the bulking mechanism 6 includes a first sieve drum 7 and a second sieve drum 8 arranged in the housing 2, and the opposite ends of the first sieve drum 7 and the second sieve drum 8 are fixedly connected, and the opening of the first sieve drum 7 away from the blocking plate 4 gradually decreases, and the opening of the second sieve drum 8 away from the blocking plate 4 gradually increases. The end of the second sieve drum 8 close to the blocking plate 4 is rotatably connected to the side of the blocking plate 4, and the end of the rotating shaft 9 away from the reduction motor 3 is movable through the housing 2 and the blocking plate 4 in turn. A connecting strip 25 is fixed on the circumferential surface of the rotating shaft 9. The connecting strip 25 Fixed on the inner wall of the first sieve drum 7, the inner walls of the first sieve drum 7 and the second sieve drum 8 are commonly connected with a plurality of long shift plates 10. When working, the reduction motor 3 drives the first sieve drum 7 and the second sieve drum 8 to rotate through the rotating shaft 9 to realize the screening of the mixed material. The agglomerated materials (affected by the binder and insufficient stirring) screened out of the mixed material are accumulated at the connection position of the first sieve drum 7 and the second sieve drum 8. When the mixed material enters the first sieve drum 7 through the hopper 5, the reduction motor 3 drives the first sieve drum 7 to rotate slowly through the rotating shaft 9 and the connecting strip 25 The first screen drum 7 drives the second screen drum 8 to rotate synchronously and slowly. After the mixed material enters from the small mouth end of the first screen drum 7, the mixed material can move smoothly and gradually to the large mouth end, effectively preventing accumulation in the first screen drum 7. In this process, the long strip plate 10 can not only carry up part of the mixed material when following the rotation of the first screen drum 7, so that it falls from a high place, and disperses the agglomerated materials with the help of the falling impact force, but also as the mixed material moves to the right in the first screen drum 7 and is affected by the shape of the first screen drum 7, the height of the mixed material carried up by the long strip plate 10 gradually increases, and the falling impact force The impact force is further enhanced, and the dispersion effect of the agglomerated materials is further improved. The opening of the second sieve drum 8 is gradually enlarged. After the preliminary screening by the first sieve drum 7, the loose part of the mixture can smoothly pass through the first sieve drum 7 and fall into the outer shell 2 and fall downward along the inner wall of the outer shell 2 to the belt conveyor 1. The agglomerated materials screened out are accumulated at the connection position of the first sieve drum 7 and the second sieve drum 8 under the action of the shapes of the first sieve drum 7 and the second sieve drum 8, ensuring that the mixture falling onto the belt conveyor 1 is uniform and has no agglomeration, thereby improving the production quality of subsequent red mud pellets.

[0047] like Figure 8 and Figure 10As shown, in this embodiment, a row of spring pieces 15 are fixed on one side of the sealing plate 4 near the reduction motor 3, and a scattering plate 14 is fixed at the bottom of the spring piece 15, and the scattering plate 14 is located inside the second screen drum 8. During the rotation of the first screen drum 7 and the second screen drum 8, a plurality of long strip paddles 10 are driven to squeeze the scattering plate 14 in turn, so that the spring piece 15 is deformed and rebounds under the force, thereby generating vibration, thereby achieving the dispersion of the agglomerated materials accumulated at the connection position of the first screen drum 7 and the second screen drum 8. When the first screen drum 7 and the second screen drum 8 rotate, a plurality of long strip paddles 10 are squeezed in turn by the scattering plate 14 fixed at the bottom of the spring piece 15, so that the scattering plate 14 drives the spring piece 15 to deform. When the inclined portion 2 12 is separated from the scattering plate 14, the spring piece 15 rebounds to generate vibration, thereby driving the scattering plate 14 to vibrate. The scattering plate 14 scatters the agglomerated materials it contacts during the vibration process, so that it is restored to a loose state, and then it can pass through the second screen drum 8 and fall onto the belt conveyor 1.

[0048] like Figure 7 and Figure 13 As shown, in this embodiment, the long strip paddle 10 includes an inclined portion 11, an inclined portion 12 and a protruding portion 13 connected in sequence, the inclined portion 11 is fixed to the inner wall of the first sieve drum 7, the inclined portion 12 and the protruding portion 13 are fixed to the inner wall of the second sieve drum 8, and the inclined portion 12 is provided with an arc-shaped guiding surface 23 on the side close to the blocking plate 4. The lengths of the several inclined portions 12 distributed on the circumference increase successively, and the inclined portions 12 with increasing lengths pass through the position of the scattering plate 14 in sequence during the rotation process, thereby changing the vibration frequency of the scattering plate 14. The inclined portion 11 plays a role in turning over the mixed material when the first sieve drum 7 rotates, thereby effectively preventing the mixed material from accumulating in the first sieve drum 7. The inclined portion 12 is close to the arc-shaped guiding surface 23 of the blocking plate 4, and when it rotates and contacts the scattering plate 14, it prevents the inclined portion 12 from The sharp corners of the edge contact the scattering plate 14, reducing the friction between the scattering plate 14 and the inclined portion 2 12. At the same time, the inclined portion 2 12, which is distributed circumferentially and increases in length, passes through the position of the scattering plate 14 in sequence during rotation. The longer inclined portion 2 12 squeezes the scattering plate 14 to cause a greater degree of deformation of the spring piece 15, and the shorter inclined portion 2 12 squeezes the scattering plate 14 to cause a smaller degree of deformation of the spring piece 15, thereby changing the vibration frequency of the scattering plate 14 to adapt to the scattering needs of agglomerated materials of different sizes. The state of small amplitude but high vibration frequency can effectively handle smaller agglomerated materials, and the state of large amplitude but low vibration frequency can effectively handle larger agglomerated materials. During the rotation of the second screen drum 8, the protrusion 13 drives the material under the scattering plate 14 to roll, further preventing the accumulation of agglomerated materials at the scattering plate 14.

[0049] like Figure 10As shown, in this embodiment, a spring piece 2 16 is fixed to the side of the spring piece 15 away from the first screen drum 7, and the side of the spring piece 2 16 is slidably connected to the side of the sealing plate 4. The spring piece 2 16 serves as an auxiliary supporting structure for the spring piece 15. On the one hand, it enhances the stability of the spring piece 15 when it is deformed by force, prevents it from being twisted or offset due to excessive force on one side, ensures the accuracy of the vibration direction, and enables the breaking plate 14 to stably exert force on the agglomerated materials. On the other hand, the sliding connection between the spring piece 2 16 and the sealing plate 4 provides a buffer space for the expansion and contraction and deformation of the spring piece 15 during frequent vibration, thereby ensuring the stable vibration of the spring piece 15.

[0050] like Figures 8-10 As shown, in this embodiment, a fan-shaped limit plate 19 is fixed on the top of the scattering plate 14, and a protective plate 17 is fixed on the side of the blocking plate 4. The protective plate 17 is located above the spring piece 15, and the side of the fan-shaped limit plate 19 is slidably connected to the side of the protective plate 17. A cutting surface 20 is provided on the top of the fan-shaped limit plate 19. The protective plate 17 is fixed to the side of the blocking plate 4 and is located above the spring piece 15. On the one hand, it prevents the agglomerated materials that are brought up by the protrusion 13 and fall from it from falling on the spring piece 15 and affecting its vibration, and on the other hand, it prevents the agglomerated materials that are brought up by the protrusion 13 and fall from it from falling on the spring piece 15 and affecting its vibration. On the one hand, the fan-shaped limit plate 19 fixed on the top of the breaking plate 14 is slidably connected to the side of the protective plate 17 to prevent the second screen drum 8 from causing the spring piece 15 on the breaking plate 14 to twist during the rolling process of the agglomerated material inside it, thereby ensuring the stable vibration of the spring piece 15. When the cutting surface 20 on the top of the fan-shaped limit plate 19 comes into contact with the agglomerated material falling from above, it uses its sharp edge to cut the agglomerated material, thereby assisting the breaking plate 14 to crush and break up the agglomerated material, thereby further improving the processing effect of the agglomerated material.

[0051] like Figure 9 As shown, in this embodiment, a plurality of protrusions 18 are provided on the top of the protective plate 17, and the protrusions 18 are in an inverted V shape. When the agglomerated materials falling from above fall onto the inverted V-shaped protrusions 18, they can have a cutting and dispersing effect on the agglomerated materials, thereby improving the dispersing ability of the protective plate 17 on the agglomerated materials.

[0052] like Figure 9 and Figure 10 As shown, in this embodiment, a plurality of long through grooves 24 are opened on the side of the breaking plate 14, and the long through grooves 24 are used to increase the friction between the breaking plate 14 and the agglomerated material, so that when the agglomerated material rolls in the second screen drum 8 and passes through the breaking plate 14, part of the agglomerated material is intercepted and collides with the passing and rolling agglomerated material, thereby achieving preliminary dispersion of the agglomerated material, and when the breaking plate 14 vibrates, the corners of the inner wall of the long through grooves 24 are used to reduce the contact area between the breaking plate 14 and the agglomerated material, increase the pressure acting on the agglomerated material, and further improve the dispersion ability of the breaking plate 14 on the agglomerated material.

[0053] like Figure 7 、 Figure 8 、 Figure 11 and Figure 12 As shown, in this embodiment, a plurality of long strip plates 10 are commonly connected with a baffle ring 21, the baffle ring 21 is trumpet-shaped, and the larger end of the opening of the baffle ring 21 is facing the side away from the blocking plate 4, and a plurality of crushing blocks 22 are fixed on the side of the baffle ring 21 close to the blocking plate 4. The crushing blocks 22 are triangular in shape, and the acute angle end of the crushing blocks 22 faces the scattering plate 14. The trumpet-shaped baffle ring 21 can make the wall thickness of the baffle ring 21 in an inclined state. When part of the agglomerated material brought up by the vibration of the scattering plate 14 hits the baffle ring 21, the agglomerated material is dispersed, thereby improving the dispersion ability of the agglomerated material and at the same time The agglomerated materials collide with the inclined wall thickness of the retaining ring 21, and the contact area between the retaining ring 21 and the agglomerated materials is increased through the inclined wall thickness, thereby improving the dispersing ability of the retaining ring 21 on the agglomerated materials. The agglomerated materials that collide with the retaining ring 21 are more easily dispersed under the action of the triangular crushing blocks 22 and the acute-angled ends of the crushing blocks 22. At the same time, when the crushing blocks 22 at different positions rotate to the bottom following the first screen drum 7, the bevels on the crushing blocks 22 face downward, thereby preventing the agglomerated materials from accumulating on the crushing blocks 22, and ensuring that the agglomerated materials can slide off the crushing blocks 22 after dispersion.

[0054] Working principle: The mixed material produced after being stirred by the forced mixer falls into the hopper 5, and then falls from the hopper 5 into the first sieve drum 7 in the shell 2. At the same time, the reduction motor 3 is started, and the output shaft of the reduction motor 3 drives the rotating shaft 9 to rotate slowly, and the rotating shaft 9 drives the eccentric disk 28 to rotate slowly. During the slow rotation of the eccentric disk 28, the eccentric disk 28 alternately squeezes the top and bottom of the inner wall of the square ring 29. When squeezing the top of the inner wall of the square ring 29, the square ring 29 moves upward along the side of the guide plate 30 and drives the vertical rod 32 to move upward. When squeezing the bottom of the inner wall of the square ring 29, the square ring 29 moves along the side of the guide plate 30 and drives the vertical rod 32 to move upward. The side of the guide plate 30 moves downward and drives the vertical rod 32 to move downward. The eccentric disk 28 alternately squeezes the square ring 29, which can make the square ring 29 drive the vertical rod 32 to reciprocate up and down. The vertical rod 32 drives the main spring bar 33 to reciprocate up and down. The main spring bar 33 follows the vertical rod 32 in the up and down movement. When the main spring bar 33 moves downward, the first wear-resistant block 38 squeezes the wear-resistant sleeve 37, causing the main spring bar 33 to bend inward while moving downward. When the main spring bar 33 moves upward, the squeezing force of the first wear-resistant block 38 on the wear-resistant sleeve 37 gradually decreases, thereby causing the main spring bar 33 to move upward. The auxiliary elastic strip 34 moves with the main elastic strip 33. When the auxiliary elastic strip 34 moves, it is affected by the deformation of the main elastic strip 33 and deforms synchronously, thereby improving the anti-blocking ability of the corner of the inner wall of the hopper 5. The small elastic strip 36 moves up and down following the auxiliary elastic strip 34. When the small elastic strip 36 moves downward, its end moves along the inclined surface on the second wear-resistant block 39. Under the extrusion of the inclined surface, the small elastic strip 36 moves downward and simultaneously moves upward. Inward bending deformation, when the end of the small elastic bar 36 moves to the vertical surface on the second wear-resistant block 39, the small elastic bar 36 stops deforming, and when the auxiliary elastic bar 34 drives the small elastic bar 36 to move upward through the shift bar 35, when the end of the small elastic bar 36 separates from the vertical surface on the second wear-resistant block 39 and fits into the inclined surface on the second wear-resistant block 39, the small elastic bar 36 simultaneously bends outward while moving upward. The design of the shift bar 35 and the small elastic bar 36 further improves the anti-blocking ability of the auxiliary elastic bar 34 at the corner of the inner wall of the hopper 5, thereby effectively preventing blockage inside the hopper 5;

[0055] The rotating shaft 9 drives the first screen drum 7 and the second screen drum 8 to rotate through the connecting bar 25. The opening of the first screen drum 7 away from the blocking plate 4 gradually decreases. During its rotation, the mixed material enters from the smaller opening end, enters the small opening end and then gradually moves to the large opening end, effectively preventing accumulation in the first screen drum 7. The inclined portion 11 of the long strip paddle 10 not only lifts up part of the mixed material when following the rotation of the first screen drum 7, causing it to fall from a high place, and disperses the agglomerated materials by the falling impact force, but also as the mixed material moves to the right in the first screen drum 7, affected by the shape of the first screen drum 7, the height of the mixed material lifted by the long strip paddle 10 gradually increases, the falling impact force is further enhanced, and the dispersion effect of the agglomerated materials is further improved. The opening of the second screen drum 8 gradually increases, and the mixed material that has been preliminarily screened by the first screen drum 7, the loose part can smoothly pass through the first screen drum 7 and fall onto the belt conveyor 1, and the agglomerated materials that have been screened are accumulated at the connection position of the first screen drum 7 and the second screen drum 8;

[0056] At the same time, during the rotation of the first screen drum 7 and the second screen drum 8, the inclined parts 21 at the ends of the several long strip shifting plates 10 connected to the inner walls thereof will sequentially squeeze the scattering plate 14 fixed at the bottom of the spring piece 15. When the inclined part 21 contacts the scattering plate 14, the scattering plate 14 is squeezed, causing the scattering plate 14 to drive the spring piece 15 to deform. When the inclined part 21 separates from the scattering plate 14, the spring piece 15 rebounds to generate vibration, thereby driving the scattering plate 14 to vibrate. During the vibration process, the scattering plate 14 breaks up the agglomerated materials it contacts, allowing them to return to a loose state and then pass through the second screen drum 8 and fall onto the belt conveyor 1. At the same time, during the vibration process of the scattering plate 14, a part of the agglomerated materials is directly broken up by the scattering plate 14, and the other part of the agglomerated materials is lifted up by the vibration of the scattering plate 14 and hits the retaining ring 21 to be crushed and dispersed. At the same time, the sharp angle end on the crushing block 22 is used to further crush the agglomerated materials, thereby further improving the dispersion effect of the agglomerated materials.

[0057] Moreover, the lengths of the inclined portions 12 on the plurality of long paddle plates 10 are different, and the lengths of the inclined portions 12 distributed circumferentially increase in sequence. When rotating, they pass through the position of the breaking up plate 14 in sequence. The inclined portion 12 with a longer length squeezes the breaking up plate 14 to cause a greater degree of deformation of the spring piece 15, and the inclined portion 12 with a shorter length squeezes the breaking up plate 14 to cause a smaller degree of deformation of the spring piece 15, thereby changing the vibration frequency of the breaking up plate 14 to adapt to the breaking up requirements of agglomerated materials of different sizes. The state of small amplitude but high vibration frequency can effectively process smaller agglomerated materials, and the state of large amplitude but low vibration frequency has a significant effect on larger agglomerated materials.

[0058] At the same time, during the rotation of the second screen drum 8, the inclined portion 12 and the protruding portion 13 of the long paddle plate 10 rotate along with the second screen drum 8. During the rotation of the inclined portion 12, the vibration frequency of the spring piece 15 is changed, and the agglomerated materials at the breaking plate 14 are moved to realize the rolling of the agglomerated materials, thereby preventing the accumulation of agglomerated materials. At the same time, during the rotation of the protruding portion 13, the materials below the breaking plate 14 are driven to roll, thereby further preventing the accumulation of agglomerated materials.

[0059] The protective plate 17 is fixed to the side of the blocking plate 4 and is located above the spring piece 15. On the one hand, it prevents the agglomerated materials that are lifted up by the protrusion 13 and fall from it from falling on the spring piece 15 and affecting its vibration. On the other hand, the fan-shaped limit plate 19 fixed on the top of the scattering plate 14 is slidably connected to the side of the protective plate 17 to prevent the second screen drum 8 from causing the spring piece 15 on the scattering plate 14 to twist during the tumbling process of the agglomerated materials inside it, thereby ensuring the stable vibration of the spring piece 15. Moreover, the cutting surface 20 set on the top of the fan-shaped limit plate 19 uses its sharp edge to cut the agglomerated materials when it comes into contact with the fallen agglomerated materials, and assists the scattering plate 14 to break up the agglomerated materials, thereby further improving the processing effect of the agglomerated materials, and finally ensuring that the mixture falling on the belt conveyor 1 is uniform and free of agglomerates. The mixture is transported to the ball press through the belt conveyor 1 and pressed into balls by the ball press.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
