Abstract
Description
Technical Field
[0001] This invention relates to the field of granulation technology, and more specifically to a supported catalyst processing device. Background Technology
[0002] In the field of industrial catalysis, the granulation of supported catalysts is a crucial step in achieving their large-scale application, directly affecting the mass transfer efficiency, mechanical stability, and catalytic activity of the catalyst in fixed-bed, moving-bed, and other reactors. Pretreatment before granulation, as a fundamental process, determines the physical properties (such as mechanical strength and pore structure uniformity) and catalytic performance (such as the dispersion of active components) of the subsequently granulated particles, and is a core prerequisite for ensuring the industrial applicability of the catalyst.
[0003] In existing technologies, the pretreatment of supported catalysts before molding typically includes three core steps: raw material preparation, additive addition, and mixing and kneading. In the raw material preparation stage, the particle size of the catalyst powder (or carrier powder) loaded with active components needs to be controlled to ensure uniform dispersion of the active components. In the additive addition stage, binders (such as boehmite and cellulose) need to be introduced to enhance particle adhesion, lubricants (such as graphite) need to be introduced to improve molding fluidity, and pore-forming agents (such as starch and ammonium bicarbonate) need to be introduced to control the pore structure. In the mixing and kneading stage, the raw materials, additives, and solvents are mixed by mechanical stirring or kneading equipment to form a homogeneous material with plasticity, providing a suitable blank for subsequent molding processes such as tableting and extrusion.
[0004] Chinese patent application CN116492922A discloses a granulation device for a hydrogenation reduction catalyst, including a granulation component. The granulation component has two granulation rings, one long and one short, nested together. Each granulation ring has a hemispherical material-containing cavity. As the clamping rollers rotate, the two granulation rings are pushed and repeatedly squeezed and separated. When the two granulation rings are separated, the powdery raw material enters between the two granulation rings. When the two granulation rings are squeezed, the powdery raw material is squeezed into a spherical shape and discharged, realizing one-time extrusion spherical granulation, ensuring that the catalyst is uniformly compressed and compact, and effectively avoiding powder shedding.
[0005] In related technologies, when granulating catalysts, a binder is added to the material to improve its adhesion and facilitate subsequent granulation. However, when adding the binder, lumps may form within the material. These lumps make it difficult to add the binder evenly, and the binder can also cause the material to clump together, resulting in poor granulation and preventing the material from forming uniform particles as required during granulation. Summary of the Invention
[0006] This invention provides a supported catalyst processing device, aiming to solve the technical problem in related technologies where, during catalyst granulation, a binder is added to the material to improve its adhesion and facilitate subsequent granulation. However, when the binder is added, clumps of material may form, making it difficult to add the binder evenly. Furthermore, the binder can easily cause agglomeration and compaction, resulting in suboptimal granulation and preventing the material from achieving the required uniform particle size during granulation.
[0007] This invention discloses a supported catalyst processing device, comprising a frame and a material turning assembly mounted on the frame. The material turning assembly includes a roller and multiple material turning plates. The roller is mounted on the frame and rotates around its own axis. The multiple material turning plates are disposed inside the roller and are evenly spaced around the roller axis. A material guiding assembly is mounted on the frame, comprising a support rod and an inclined plate. The support rod is fixedly mounted on the frame, and the inclined plate is mounted on the support rod and is arranged along the roller axis. A gap is provided between the two sides of the inclined plate and the roller for the material turning plates to pass through. A crushing assembly is mounted at the lower end of the inclined plate, comprising a pressing plate and a support plate. The support plate is rotatably mounted at the lower end of the inclined plate, and a second torsion spring is provided at its hinge. Two support columns are provided on the upper surface of the lower end of the inclined plate. The pressing plate is located above the support plate, and both ends of the pressing plate are respectively hinged to the two support columns, and a first torsion spring is provided at its hinge.
[0008] Its effects are as follows: By incorporating a tipping component, a guiding component, and a crushing component, the tipping component efficiently flips and lifts the material from the bottom of the drum onto the guiding component. Upon receiving the material, the guiding component uses its mesh structure to evenly distribute the material across the entire surface of the mixture, significantly accelerating the mixing speed and improving material uniformity, while reducing mixing time. Simultaneously, addressing potential agglomeration issues, the guiding component's built-in screening component identifies and separates agglomerated materials, collecting and guiding them to the crushing component. The crushing component then crushes these agglomerated materials, ensuring consistent particle size and resolving the problem of uneven mixing caused by agglomerated materials that cannot be crushed during the mixing process, ultimately improving overall mixing efficiency and quality.
[0009] Preferably, the extrusion plate and the support plate are provided with a gap for the agglomerated material to pass through at one end near the inclined plate, the other end of the extrusion plate and the support plate abut against each other, the support plate is located outside the extrusion plate in the extension direction of the inclined plate, and protrusions are provided on the end faces of the support plate and the extrusion plate that are close to each other.
[0010] Its effect is that by setting protrusions on the extrusion plate and the support plate, the extrusion plate and the support plate can quickly crush the material inside them.
[0011] Preferably, the two ends of the inclined plate are respectively hinged to the support rod, and the support rod is provided with a limiting component. The limiting component is slidably disposed along the support rod and limits the rotation angle of the inclined plate.
[0012] Its effect is that by limiting the angle of the inclined plate's rotation through the limiting component, the inclined plate vibrates after the crushing component crushes the material, allowing the material on the inclined plate to be screened quickly.
[0013] Preferably, a limiting nut is provided between the limiting component and the support rod, and the top rods on both sides of the limiting component are telescopically provided.
[0014] Preferably, the surface of the inclined plate is perforated, and the surface of the inclined plate can be covered with perforated plates of different aperture sizes.
[0015] Its effect is that by setting mesh plates of different diameters, it can adapt to materials of different diameters, thus enhancing the adaptability of the equipment.
[0016] Preferably, limit nuts are provided between the plurality of the tipping plates and the roller to adjust the tilt angle of the tipping plates.
[0017] Preferably, the frame is provided with a spraying assembly, which includes a spraying rod and two fixing rods. The two fixing rods are disposed on the frame, and the spraying rod is disposed on the upper side of the inclined plate along the length direction of the roller.
[0018] Its effect is that by setting up a spraying component, the adhesive is sprayed directly onto the material on the inclined plate, allowing the material after the adhesive is sprayed to be quickly screened, and the clumped material is moved to the crushing component for crushing.
[0019] Preferably, the frame is provided with a drive device, which causes the roller to rotate around the axis.
[0020] Preferably, the spraying assembly is externally connected to an inlet pump and a storage tank.
[0021] Preferably, a feed hopper is provided on one side of the frame, and a spiral blade is provided at the outlet end of the roller.
[0022] The beneficial effects of this invention are as follows: 1. By setting up a material turning component, a material guiding component, and a crushing component, the material is turned from the bottom of the drum onto the material guiding component. The material guiding component evenly spreads the material onto the surface of the material at the bottom of the drum to accelerate the bonding speed between the material and the adhesive. At the same time, for the agglomerated material, as well as the agglomerated material generated after the addition of adhesive, the material guiding component filters and screens the material and collects it to the crushing component for crushing. This solves the problem of uneven mixing caused by the agglomerated material not being crushed during mixing.
[0023] 2. By setting up a spraying component, the adhesive is sprayed directly onto the material on the inclined plate, allowing the material after the adhesive is sprayed to be quickly screened. Clumped material is moved to the crushing component for crushing, thus solving the problem of material accumulation and clumping caused by uneven adhesive spraying.
[0024] 3. Through structural design and synergistic interaction between components, the problems of material agglomeration, uneven binder distribution, and low mixing efficiency in existing technologies, which prevent materials from achieving optimal granulation, are effectively solved. This significantly improves the quality of material pretreatment during catalyst preparation. It provides higher-quality materials with more uniformity, good plasticity, and moderate strength for subsequent granulation steps, thereby ensuring the mechanical strength, pore structure, and catalytic activity of the supported catalyst product.

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0037] Before granulation, a binder is added to the material to improve its adhesion and facilitate granulation. However, existing equipment struggles to handle lumps in the material before granulation. The presence of lumps makes it difficult to add the binder evenly, and the binder can cause the material to clump together, resulting in poor granulation.
[0038] like Figures 1 to 10 As shown, a supported catalyst processing device of the present invention includes a frame 1, a turning component 2, a guiding component 3, a crushing component 4, and a spraying component 5. The turning component 2 is horizontally arranged on the frame 1, the guiding component 3 is inserted into the turning component 2 and fixed on the frame 1, the crushing component 4 is arranged at the lower end of the guiding component 3, and the spraying component 5 is arranged between the guiding component 3 and the turning component 2. It is used to add a binder to the material on the guiding component 3. The material to be mixed is added to the turning component 2, and the turning component 2 turns the material at the bottom onto the guiding component 3. After screening by the guiding component 3, the qualified material is evenly sprinkled on the top of the bottom material, and the unqualified agglomerated material moves along the guiding component 3 to the crushing component 4, where the crushing component 4 crushes the agglomerated material, reducing the inability of the material to be granulated normally due to agglomeration.
[0039] like Figures 3 to 10 As shown, frame 1 is the basic support structure of the entire equipment, welded from high-strength steel to ensure the stability and load-bearing capacity of the equipment. The structural design of frame 1 takes into account the overall center of gravity distribution of the equipment and the convenience of operation. Bearing seats for installing the material tilting assembly 2 and mounting brackets for fixing the material guiding assembly 3 and the spraying assembly 5 are provided on both sides of frame 1.
[0040] The bottom of the frame 1 is equipped with retractable support feet (not shown in the figure). These support feet allow the operator to adjust the overall tilt angle of the equipment according to process requirements. At the same time, when the ground on which the frame 1 is placed is not flat, the length of multiple support feet can be adjusted to adapt to different positions. Especially after the material is mixed, the roller 21 can be tilted by adjusting the tilt angle, which facilitates the rapid discharge of materials, significantly improves the discharge efficiency and shortens the production cycle.
[0041] The frame 1 also integrates a control panel and power interface for easy operation and maintenance. A feed hopper 9 is provided on one side of the frame 1 and is connected to one side of the drum 21. The feed hopper 9 facilitates the quick and safe feeding of materials to be processed, such as catalyst powder, carrier, and additives, into the drum 21 inside the equipment by operators or automated feeding systems.
[0042] like Figures 2 to 6 As shown, the material-turning assembly 2 is horizontally mounted on the frame 1. The assembly consists of a cylindrical roller 21 and multiple turning plates 22 evenly distributed around the inner wall of the roller 21. The roller 21 is made of wear-resistant and corrosion-resistant stainless steel. Both ends of the roller 21 are rotatably mounted on the frame 1 via friction wheels, ensuring smooth rotation around its own axis. The rotational power of the roller 21 originates from a drive device (as shown in the figure) mounted on the frame 1. This drive device includes one or more drive motors and a transmission mechanism. The drive motors drive the friction wheels through the transmission mechanism.
[0043] Specifically, the drive unit is equipped with multiple friction wheels, which are mounted on the frame 1 and make frictional contact with the outer wall of the drum 21. The drive motor drives these friction wheels to rotate, which in turn drives the drum 21 to rotate continuously and stably around its central axis through friction. The rotational speed of the drum 21 is adjustable to adapt to the needs of different materials.
[0044] like Figures 2 to 9 As shown, multiple tilting plates 22 are evenly spaced and arranged circumferentially on the inner wall of the drum 21, extending along the axial length of the drum 21. The tilting plates 22 are connected to the inner wall of the drum 21 via a hinged structure, and a limiting nut is provided at the hinge to fix the tilting plates 22. This hinged fixing method allows the tilting plate 22 to have an adjustable tilt angle. Operators or automated systems can adjust the tilt angle of the tilting plate 22 according to the characteristics of the material being processed, such as flowability, density, and viscosity. By adjusting the tilt angle, the height at which the material is turned over and the throwing distance can be adjusted, thereby achieving a better material turning effect.
[0045] When the drum 21 rotates at a set speed, the material-turning plates 22 on its inner wall continuously scoop up and turn the material at the bottom of the drum 21 upwards. As the drum 21 rotates, the material that has been turned up reaches a certain height and, due to gravity, falls freely downwards along the surface of the material-turning plates 22. In this process, the material is effectively turned from the bottom to the top and evenly spread onto the inclined plates 32 of the material-guiding assembly 3 located inside the drum 21.
[0046] Furthermore, a spiral blade is provided inside the discharge end of the drum 21. When the drum 21 rotates in the forward direction, the spiral blade moves the material at the discharge end of the drum 21 towards the middle position. When discharge is required, the drum 21 rotates in the reverse direction to discharge the material inside the drum 21 from the discharge port and enter the granulation section at the rear end for granulation (not shown in the granulation section diagram). The conical part of the feed end of the drum 21 is fixedly mounted on the frame 1. The conical part of the feed end of the drum 21 is fixedly connected to the feed hopper 9. The conical part of the feed end of the drum 21 rotates relative to the drum 21.
[0047] like Figures 3 to 8 As shown, the material guide assembly 3 is installed inside the roller 21 of the material turning assembly 2. One end of the material guide assembly 3 is fixed to the conical portion at the feed end of the roller 21, located at the feed hopper 9. The material guide assembly 3 includes a support rod 31 and an inclined plate 32. The support rod 31 is the main support structure of the material guide assembly 3, made of high-strength steel, ensuring that the inclined plate 32 maintains a stable position and angle during operation. The support rod 31 is firmly fixed to the conical portion at the feed end and extends along a direction perpendicular to the axis of the roller 21.
[0048] The inclined plate 32 is the core functional component of the material guiding assembly 3. It is mounted on the support rod 31 and arranged at an angle along the axis of the roller 21. The surface of the inclined plate 32 has a perforated design, meaning that numerous holes are evenly distributed on the inclined plate 32. This perforated design allows qualified fine particles to pass through directly. To accommodate materials with different particle sizes, the surface of the inclined plate 32 can also be flexibly covered with perforated plates of different apertures. By simply replacing the perforated plates, the equipment can be quickly adjusted to meet the particle size requirements of different materials, greatly improving the versatility and adaptability of the equipment.
[0049] There are gaps between the two sides of the inclined plate 32 and the inner wall of the roller 21. The size of these gaps is sufficient to allow the tilting plate 22 to pass through when the roller 21 rotates without interfering with the inclined plate 32, thus ensuring the smooth operation of the equipment.
[0050] The inclined plate 32 is hinged to the support rod 31, giving the inclined plate 32 a certain degree of rotational freedom. To limit the rotation angle of the inclined plate 32, a limiting component 311 is specially provided on the support rod 31. The limiting component 311 slides along the support rod 31 and is equipped with two telescopic push rods 312. By adjusting the position of the limiting component 311 on the support rod 31 and the telescopic length of the push rods 312, the rotation angle range of the inclined plate 32 can be limited. Furthermore, a limiting nut (not shown in the figure) is also fitted between the limiting component 311 and the support rod 31 to lock the inclined plate 32 after the angle is adjusted, preventing accidental rotation during operation.
[0051] This adjustable angle design allows the inclined plate 32 to return to the set angle after the crushing component 4 has finished processing the agglomerated material. This setting helps to accelerate the downward movement of the material on the inclined plate 32 and its passage through the screen holes, thereby speeding up the material screening efficiency.
[0052] During operation, the material turned over by the turning component 2 falls onto the inclined plate 32. Fine particles that meet the particle size requirements are evenly scattered back onto the top of the material to be mixed inside the drum 21 through the holes in the perforated or mesh plate on the inclined plate 32. Larger particles that fail to pass through the screen holes or clumps that have formed will gradually move towards the lower end of the inclined plate 32 along its inclination direction and will eventually be guided to the crushing component 4 for processing.
[0053] like Figures 2 to 8 As shown, the crushing component 4 is located at the lower end of the inclined plate 32 in the feeding component 3, and is specifically used to receive and crush the agglomerated material sliding down from the inclined plate 32. The crushing component 4 mainly consists of a pressing plate 41 and a support plate 42, which work together to process the agglomerated material.
[0054] The support plate 42 is rotatably mounted on the lower end of the inclined plate 32 via a hinge structure. A torsion spring 2 is provided at the hinge, which provides a preset reset torque to ensure that the support plate 42 can quickly return to its initial position after the external force is removed. Preferably, when the support plate 42 is in the initial state, the support plate 42 and the inclined plate 32 are on the same plane.
[0055] Two support columns 321 are symmetrically arranged on the upper surface of the lower end of the inclined plate 32. The support columns 321 are telescopic rods. The telescopic rods have high practical value, as the operator can adjust the length of the support columns 321 manually or automatically according to the average size of the agglomerated material being processed. The distance between the extrusion plate 41 and the support plate 42 on the side closest to the inclined plate 32 can be controlled, thus allowing the equipment to flexibly adapt to crushing agglomerated materials of different sizes.
[0056] like Figures 4 to 9 As shown, the extrusion plate 41 is located on the upper side of the support plate 42, and both ends of the extrusion plate 41 are connected to the two support columns 321 by hinge structures. A torsion spring is also provided at the hinge position of the extrusion plate 41. The torsion spring and the torsion spring work together to provide a restoring force for the extrusion plate 41.
[0057] A gap is provided between the extrusion plate 41 and the support plate 42 at the end near the inclined plate 32. The size of this gap can be adjusted under different conditions to ensure that agglomerated materials can enter smoothly and to effectively position the materials in the extrusion and crushing zone after they enter. The other ends of the extrusion plate 41 and the support plate 42, that is, the ends away from the inclined plate 32, are tightly abutted to form a closed working area. The support plate 42 is located outside the extrusion plate 41 in the extension direction of the inclined plate 32, so that when the tilting plate 22 rotates, it will first separate from the extrusion plate 41 and then separate from the support plate 42, further enabling a collision action between the extrusion plate 41 and the support plate 42.
[0058] To enhance the crushing effect, protruding structures are provided on the end faces of the extrusion plate 41 and the support plate 42 that are close to each other. These protruding structures can generate local high pressure and shear force on the agglomerated material during the extrusion process, making it easier to crush and pulverize, thus improving the crushing efficiency.
[0059] In the initial stage of operation, i.e. the initial state of the equipment, the support plate 42 and the inclined plate 32 are usually located on the same plane, and the end of the pressing plate 41 away from the inclined plate 32 is in contact with the support plate 42.
[0060] When the drum 21 rotates, it drives the tipping plate 22 to move. The tipping plate 22 periodically rotates above the crushing component 4, contacts and pushes the extrusion plate 41 downward. Under the action of force, the extrusion plate 41 and the support plate 42 will flip downward simultaneously. During this flipping process, the agglomerated material falling between the extrusion plate 41 and the support plate 42 will be subjected to the rubbing and shearing action of the two plates. In particular, the concentrated force exerted on the agglomerated material by the protruding structure will cause the agglomerated material to be quickly crushed.
[0061] As the tilting plate 22 continues to rotate and passes the extrusion plate 41, the extrusion plate 41 quickly returns to its initial position due to the action of the first torsion spring. Subsequently, after the tilting plate 22 rotates further and passes the support plate 42, the support plate 42 also quickly returns to its initial position due to the action of the second torsion spring. During this resetting process, the support plate 42 collides with the extrusion plate 41. This collision effectively shakes off residual material adhering to the surfaces of the extrusion plate 41 and the support plate 42, preventing material from adhering and accumulating for a long time, and ensuring the continuous and efficient operation of the crushing assembly 4. The crushing assembly 4 can not only efficiently crush agglomerates in materials, but also has self-cleaning capabilities, thus solving the problem of difficult handling of agglomerated materials when adding binders, and ensuring the uniformity of the materials.
[0062] like Figures 4 to 10 As shown, the spraying assembly 5 is mounted on the frame 1, positioned above the inclined plate 32 and between the roller 21, allowing the adhesive to directly act on the material on the inclined plate 32. The spraying assembly 5 consists of a spraying rod 51 and two fixing rods 52. The two fixing rods 52 are made of high-strength material. The support rod 31 on one side of the feed hopper 9 is fixedly mounted in the conical area, while the support rod 31 on the other side is positioned against the bottom of the roller 21. The two fixing rods 52 provide reliable support for the spraying rod 51.
[0063] The spray bar 51 is arranged parallel to the length of the roller 21 and located above the inclined plate 32, ensuring that its spraying area can cover the material moving on the inclined plate 32. The outer side of the spray bar 51 is connected to a feeding assembly via a pipe. This feeding assembly is a complete fluid delivery system, including a liquid pump 7 and a storage tank 8. The storage tank 8 is used to store liquid adhesive or pre-dispersed adhesive slurry, and the liquid pump 7 is responsible for drawing the adhesive from the storage tank 8 at a controlled flow rate and delivering it to the spray bar 51 via the pipe. The spray bar 51 has multiple micro-spray holes or nozzles (not shown in the figure) evenly distributed along its length, ensuring that the adhesive can be sprayed evenly and continuously onto the material surface on the inclined plate 32 in a mist or fine stream.
[0064] During equipment operation, when the material is turned over by the tipping component 2 and falls onto the inclined plate 32 for screening and movement, the spraying component 5 begins to work. The liquid inlet pump 7 precisely sprays the adhesive onto the material on the inclined plate 32 at a preset flow rate. This spraying method avoids the problem of excessive local adhesive that may occur when the adhesive is added to the bottom of the roller 21 all at once in the traditional method, thus effectively preventing the material from clumping together due to excessive local adhesive.
[0065] The adhesive is sprayed when the material is in a dynamically dispersed state, ensuring that the adhesive can fully contact the surface of more material particles, thereby promoting the rapid penetration and uniform dispersion of the adhesive throughout the material system.
[0066] After spraying, the material continues to move on the inclined plate 32. The qualified particles are evenly scattered and further combined with the adhesive, while any lumps that may form will continue to slide to the crushing component 4 for processing. This solves the problem that the material cannot be granulated due to uneven distribution after the addition of adhesive, ensuring the continuity of the production process and the stability of product quality.
[0067] like Figures 3 to 7 As shown, in more complex application scenarios, this equipment can also integrate a vacuum system 6 and a heat transfer system 10 to further optimize the material handling process.
[0068] The vacuum system 6 can be connected to the sealed space of the drum 21 for negative pressure operation under specific conditions. For example, for materials that are easily oxidized, deliquescent, or sensitive to air, the vacuum environment can effectively prevent adverse reactions during the mixing process, ensuring the activity and stability of the materials.
[0069] The heat transfer medium system 10 can be connected to the jacket of the drum 21 or through other heat transfer media to heat or keep the material inside the drum 21 warm. For example, some adhesives are more active at specific temperatures, or materials have better flowability at certain temperatures. The heat transfer medium system 10 can provide the necessary temperature control to optimize the mixing effect and the activation process of the adhesive. At the same time, for materials that need to be dried, the heat transfer medium system 10 can also provide the necessary heat transfer to accelerate the drying rate.
[0070] Working principle: The catalyst powder, carrier, and various additives to be mixed are fed into the drum 21 through the feed hopper 9. The drive device is started, and the drive motor drives the friction wheel to rotate, which in turn causes the drum 21 to rotate around its own axis. As the drum 21 rotates, multiple tipping plates 22 on its inner wall continuously "scoop up" the material at the bottom of the drum 21 and turn it upward. The material carried to a higher position by the tipping plates 22 falls freely along the surface of the tipping plates 22 and is evenly spread onto the inclined plate 32 of the guide assembly 3 set inside the drum 21.
[0071] After the material falls onto the inclined plate 32, due to the hollow design of the inclined plate 32 and the mesh plate laid on it, fine particles that meet the particle size requirements will pass through the holes and be evenly "showered" back to the top of the material to be mixed inside the roller 21.
[0072] While the material is being screened and moved on the inclined plate 32, the spraying assembly 5 starts working. The liquid pump 7 draws liquid adhesive from the storage tank 8 and sprays it evenly onto the material surface on the inclined plate 32 in the form of a fine mist or a uniform water flow through multiple nozzles on the spray rod 51. This spraying method ensures full contact between the adhesive and the material, avoids local over-dispensing, and thus prevents clumping and caking caused by uneven adhesive distribution.
[0073] For larger particles or agglomerated materials that fail to pass through the sieve holes of the inclined plate 32, they will gradually slide towards the lower end of the crushing component 4 along the inclined direction of the inclined plate 32. When the tipping plate 22 rotates above the crushing component 4, it will periodically contact and push the extrusion plate 41 downward. Under force, the extrusion plate 41 and the support plate 42 flip downward synchronously, applying rubbing and shearing forces to the agglomerated material falling between them. Under the action of the end face protrusions, the agglomerated material is efficiently crushed into fine particles.
[0074] After the tipping plate 22 passes over the extrusion plate 41, torsion springs one and two quickly reset the extrusion plate 41 and the support plate 42. During the reset process, the collision between the extrusion plate 41 and the support plate 42 shakes off the attached material, achieving self-cleaning. The crushed fine particles fall back into the drum 21 and continue to mix with the remaining materials.
[0075] After the material has been thoroughly mixed, crushed, and homogenized with binder to reach the preset granulation blank state, the operator can adjust the length of the retractable support legs at the bottom of the frame 1 to tilt the roller 21 as a whole. At this time, the roller 21 reverses, and the spiral blades at the outlet end of the roller 21 discharge the uniformly mixed and qualified material from the roller 21 into the next granulation process.
[0076] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
