[0049] Please see Figures 1 to 3 This embodiment provides a powdered filter cake crushing device, including a frame 1, a first star wheel group 21, a second star wheel group 31, a drive group 5, and a transmission group 4. The frame 1 has a first sidewall 11 and a second sidewall 12, which are arranged opposite to each other. The inner side of the first sidewall 11 is provided with first wall teeth 111 arranged at intervals according to a first preset method, and the inner side of the second sidewall 12 is provided with second wall teeth 121 arranged at intervals according to a second preset method. The first star wheel group 21 is located on the side close to the first sidewall 11, and the first star wheel group 21 includes a first star wheel 2. 1. A first rotating shaft 22, and multiple first star wheels 21 are spaced apart on the first rotating shaft 22. A first wall tooth 111 is accommodated on one side between two adjacent first star wheels 21. A group 3 of second star wheels 31 is arranged on the side near the second sidewall 12. The group 3 of second star wheels 31 includes second star wheels 31 and a second rotating shaft 32. Multiple second star wheels 31 are spaced apart on the second rotating shaft 32. A second wall tooth 121 is accommodated on one side between two adjacent second star wheels 31, and a first star wheel 21 is accommodated on the other side of two adjacent second star wheels 31.

[0050] The drive group 5 includes a first drive wheel 51, a first driven wheel 52, and a drive unit 53. The drive unit 53 is connected to the first drive wheel 51, and the first drive wheel 51 is connected to the first driven wheel 52 in a transmission connection. The first driven wheel 52 is sleeved on one end of the first rotating shaft 22. The transmission group 4 includes a first transmission wheel 41 and a second transmission wheel 42. The first transmission wheel 41 is sleeved on the other end of the first rotating shaft 22, and the second transmission wheel 42 is sleeved on one end of the second rotating shaft 32. The second transmission wheel 42 is arranged on the same side as the first transmission wheel 41, and the first transmission wheel 41 and the second transmission wheel 42 mesh.

[0051] In some embodiments, the first drive wheel 41 and the second drive wheel 42 rotate in opposite directions.

[0052] The powdered filter cake crushing device in this embodiment mainly consists of a frame 1, a first star wheel group 21, a second star wheel group 31, a drive group 5, and a transmission group 4. The frame 1 includes a first sidewall 11 and a second sidewall 12 arranged opposite to each other. The inner side of the first sidewall 11 is provided with first wall teeth 111 arranged in a first preset manner, and the inner side of the second sidewall 12 is provided with second wall teeth 121 arranged in a second preset manner. The first wall teeth 111 and the second wall teeth 121 are used to cooperate with the first star wheel group 21 and the second star wheel group 31 to form a shearing surface. The first star wheel group 21 is arranged close to the first sidewall 11 and includes multiple first star wheels 21 spaced apart and mounted on the first rotating shaft 22. A first wall tooth 111 is embedded between adjacent first star wheels 21. The second star wheel group 31 is arranged close to the second sidewall 12 and includes multiple second star wheels 31 spaced apart and mounted on the second rotating shaft 32. A second wall tooth 121 is embedded on one side of adjacent second star wheels 31, and a first star wheel 21 is embedded on the other side, forming an interlocking structure. The drive group 5 includes a first drive wheel 51, a first driven wheel 52 and a drive unit 53 to realize power input, wherein the first driven wheel 52 is fixed to the end of the first rotating shaft 22; the transmission group 4 includes a first transmission wheel 41 (connected to the first rotating shaft 22) and a second transmission wheel 42 (connected to the second rotating shaft 32) arranged on the same side and meshing with each other to realize dual-axis linkage.

[0053] During operation, the drive unit 53 drives the first drive wheel 51 to rotate, which in turn drives the first rotating shaft 22 and the first star wheel 21 group 2 to rotate via the first driven wheel 52. Simultaneously, through the meshing transmission of the first transmission wheel 41 and the second transmission wheel 42, the second rotating shaft 32 and the second star wheel 31 group 3 are driven to rotate in opposite directions. When powdered filter cakes such as activated carbon enter the crushing zone, during the opposite rotation of the first star wheel 21 and the second star wheel 31, the teeth of the first star wheel 21 and the first wall teeth 111, the teeth of the second star wheel 31 and the second wall teeth 121, and the teeth of the first star wheel 21 and the second star wheel 31 form multiple shearing actions. This is suitable for sticky filter cakes after plate and frame filtration, effectively breaking down material agglomeration. The crushed particles are evenly dispersed due to the confining effect, avoiding secondary agglomeration caused by traditional roller pressing.

[0054] In this embodiment, the spatially staggered arrangement of the first star wheel group 21 and the second star wheel group 31, combined with the first wall teeth 111 and the second wall teeth 121, achieves thorough shearing of the filter cake. Compared with traditional double-roll crushers, the cooperation between the first star wheel 21 and the first wall teeth 111, and the cooperation between the second star wheel 31 and the second wall teeth 121, can handle the clumps scattered to the edges, while the meshing of the first star wheel 21 and the second star wheel 31 targets the filter cake scattered in the middle, which is also the main crushing area. The transmission group 4 ensures that the rotation speeds of the first rotating shaft 22 and the second rotating shaft 32 are strictly synchronized, avoiding material compression and accumulation caused by speed difference, resulting in a more uniform moisture content distribution after the activated carbon filter cake is crushed, and significantly reducing the probability of material blockage on the conveyor belt.

[0055] In some embodiments, the first star wheel 21 is configured as a gear structure; and / or, the second star wheel 31 is configured as a gear structure.

[0056] In this embodiment, the first star wheel 21 and the second star wheel 31 are configured as a gear structure, which refers to a rotating cutting element with a standard involute tooth profile or a special tooth profile. The first star wheel 21 is mounted on the first rotating shaft 22 and forms a shear pair with the first wall teeth 111 of the first sidewall 11 with a fixed clearance; the second star wheel 31 is mounted on the second rotating shaft 32 and forms another shear pair with the second wall teeth 121 of the second sidewall 12.

[0057] When processing viscous filter cakes such as activated carbon, the drive unit 53 drives the first rotating shaft 22 to rotate via the first drive wheel 51. The first star wheel 21, with its gear structure, forms a precise, progressive shearing action with the first wall teeth 111, effectively preventing material adhesion. Simultaneously, through the meshing transmission of the first transmission wheel 41 and the second transmission wheel 42, the second star wheel 31 on the second rotating shaft 32 (if a gear structure) rotates synchronously in opposite directions, forming a mirror shearing system with the second wall teeth 121. When both the first star wheel 21 and the second star wheel 31 are gear structures, the continuous cutting action generated by their meshing effectively decomposes fibrous agglomerates. The tooth groove space of the gears also forms a temporary storage cavity, preventing instantaneous material overload. This method is particularly suitable for processing high-viscosity filter cakes produced by plate and frame filter presses, and its tooth profile parameters can be adjusted according to the material characteristics, including the module and tooth height.

[0058] In some embodiments, the first star wheel 21 has a circumferentially spaced array of six first gear teeth 211; the second star wheel 31 has a circumferentially spaced array of six second gear teeth 311.

[0059] In this embodiment, the first star wheel 21 has a circumferentially spaced array of six first gear teeth 211, and the second gear teeth 311 has a circumferentially spaced array of six second gear teeth 311. The circumferentially spaced array refers to the arrangement of the gear teeth evenly distributed along the circumference of the star wheel. The first gear teeth 211 refer to the cutting structures protruding from the outer edge of the first star wheel 21, and their tooth profiles are complementary to both the first wall teeth 111 and the second gear teeth 311. The second gear teeth 311 refer to the cutting units corresponding to the outer edge of the second star wheel 31, and together with the second wall teeth 121 and the first gear teeth 211, they form a dynamic shearing pair. Six first gear teeth 211 are distributed at equal angles on the circumference of the first star wheel 21, and six second gear teeth 311 are arranged in a mirror-symmetrical manner on the second star wheel 31. The phase difference design between the first gear teeth 211 and the second gear teeth 311 ensures that at least one pair of teeth are always in an effective meshing state when the first star wheel 21 and the second star wheel 31 are meshing. Furthermore, when the first gear teeth 211 are placed horizontally, the edge of the first gear teeth 211 forms a 30-degree angle with the horizontal baseline, forming a conical structure between the end of the first gear teeth 211 and the root of the first gear teeth 211, which facilitates the cutting in and cutting out of materials. Similarly, the structure of the second gear teeth 311 can be the same as that of the first gear teeth 211 to improve the crushing effect.

[0060] During the crushing process, the first star wheel 21 with six first gear teeth 211 and the second star wheel 31 with six second gear teeth 311 work together to form a high-frequency shearing network. When the drive unit 53 is started, for every 60 degrees of rotation of the first star wheel 21, one first gear tooth 211 and the first wall tooth 111 complete one shearing action, while the second star wheel 31 rotates synchronously in the opposite direction, causing its second gear tooth 311 and the second wall tooth 121 to perform corresponding shearing. The alternating meshing of the first gear teeth 211 and the second gear teeth 311 generates a wave-like crushing trajectory, and the continuous force provided by the six-tooth structure can effectively decompose the three-dimensional network agglomerates in the activated carbon filter cake. Especially when processing high-viscosity materials, the symmetrical layout of the six teeth can balance the radial force and avoid unilateral wear. The six first gear teeth 211 and the six second gear teeth 311 make the material present a spiral propulsion state in the crushing chamber, which significantly improves the throughput efficiency.

[0061] In some embodiments, the first wall tooth 111 and the first star wheel 21 are staggered and interlocked, and the first star wheel 21 can slide relative to the first wall tooth 111; the second wall tooth 121 and the second star wheel 31 are staggered and interlocked, and the second star wheel 31 can slide relative to the second wall tooth 121; the first star wheel 21 and the second star wheel 31 are staggered and interlocked. The teeth of the first star wheel 21 and the second star wheel 31 are preferably made of high-chromium alloy to ensure wear resistance under sliding friction conditions; the tooth grooves of the first wall tooth 111 and the second wall tooth 121 are designed with a gradually expanding structure to facilitate material flow and prevent blockage.

[0062] In some embodiments, the first drive wheel 41 is configured as a gear structure; and / or, the second drive wheel 42 is configured as a gear structure.

[0063] The first transmission wheel 41 is configured as a gear structure, meaning it adopts a standard involute tooth profile or a specially modified tooth profile. Similarly, the second transmission wheel 42 can also adopt the same or different gear configuration. The gear structure is preferably a hardened gear with a carburized and quenched surface to improve fatigue resistance, and its tooth profile curve is optimized to reduce meshing impact. Utilizing the constant speed ratio characteristic of gear transmission, the synchronization accuracy between the first star wheel 21 and the second star wheel 31 is ensured, while the oil film formed during gear meshing effectively reduces frictional losses in the transmission system.

[0064] In some embodiments, a transmission belt 54 is provided between the first drive wheel 51 and the first driven wheel 52. The transmission belt 54 is an annular belt made of rubber composite material, with equidistantly distributed V-shaped or toothed structures on its inner side, which mesh with the grooves of the first drive wheel 51 and the first driven wheel 52 for transmission.

[0065] In some embodiments, a discharge port is also provided below the frame 1, and the device further includes a hopper 6, which is disposed at the discharge port. The discharge port refers to the open structure located at the bottom of the frame 1, and its cross-sectional shape is preferably rectangular or circular. The size is designed according to the material characteristics and is used to discharge the crushed material from the device. The hopper 6 is a funnel-shaped guide component connected below the discharge port, made of wear-resistant steel plate, and its inner wall can be lined with a polymer liner to reduce frictional resistance. The inclination angle of the hopper 6 is optimized to ensure that the material slides smoothly by gravity, and its bottom can be equipped with a flange interface for docking with downstream conveying equipment.

[0066] In some embodiments, the frame 1 further includes a third sidewall 13 and a fourth sidewall 14, the third sidewall 13 and the fourth sidewall 14 being disposed opposite to each other, and the first sidewall 11, the fourth sidewall 14, the second sidewall 12 and the third sidewall 13 sequentially enclosing the frame 1; the first star wheel 21 group 2 and the second star wheel 31 group 3 are both disposed between the third sidewall 13 and the fourth sidewall 14.

[0067] In this embodiment, the frame 1 is formed by a first side wall 11, a second side wall 12, a third side wall 13, and a fourth side wall 14. The third side wall 13 and the fourth side wall 14 are arranged opposite to each other and together with the first side wall 11 and the second side wall 12, form a closed box structure. The first star wheel group 21 and the second star wheel group 31 are arranged laterally between the third side wall 13 and the fourth side wall 14, and their two ends of the rotating shaft are fixed to the third side wall 13 and the fourth side wall 14 respectively through bearing seats. The frame 1 is preferably welded from Q345B steel plate, and internal reinforcing ribs can be provided to improve structural rigidity. The joints of each side wall are sealed to prevent material leakage.

[0068] In some embodiments, a first adjusting long slot 131 is provided on the third sidewall 13; a second adjusting long slot is provided on the fourth sidewall 14, and the first adjusting long slot 131 and the second adjusting long slot are arranged parallel to each other; the first star wheel 21 group 2 is arranged in the frame 1 through the first adjusting long slot 131 and the second adjusting long slot; the second star wheel 31 group 3 is arranged in the frame 1 through the first adjusting long slot 131 and the second adjusting long slot.

[0069] The first and second adjusting elongated slots 131 and 14 are respectively formed on the third sidewall 13 and the fourth sidewall 14, and are horizontal or inclined waist-shaped hole structures. The first and second adjusting elongated slots 131 and 14 are formed by laser cutting, and their inner walls are hardened to improve wear resistance. The bearing seats of the first star wheel group 21 and the second star wheel group 31 are connected to the elongated slots by bolts, and the bearing seats can slide and lock within the range of the elongated slots. By moving the bearing seats of the first star wheel group 21 and the second star wheel group 31 along the first and second adjusting elongated slots 131 and 14, the meshing gap between the first star wheel group 21 and the second star wheel group 31 can be changed in real time, thereby adapting to the crushing requirements of materials with different particle sizes.

[0070] Unlike existing technologies, the above-mentioned technical solution provides a powdered filter cake crushing device. Through the first wall teeth 111 on the first sidewall 11 and the second wall teeth 121 on the second sidewall 12 within the frame 1, combined with the staggered arrangement of the first star wheel group 21 and the second star wheel group 31, and the linkage control of the drive group 5 and the transmission group 4, a dual shearing action on the powdered filter cake is achieved. This effectively solves the problem of filter cake adhesion and incomplete crushing. The alternating engagement of the first star wheel 21 and the second star wheel 31 ensures more uniform force on the material, resulting in a significant reduction in particle size and increased looseness after crushing. Simultaneously, the meshing transmission of the first transmission wheel 41 and the second transmission wheel 42 optimizes power distribution, reduces energy consumption, and avoids the risk of bridging in wet carbon silos.

Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
