Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a crusher for catalysts. Background Technology

[0002] Catalysts play a crucial role in chemical industrial production. In many processes, such as catalyst preparation, post-use recovery, or regeneration, it is often necessary to crush lumpy or large-particle catalysts to meet the particle size requirements of subsequent processes. Therefore, catalyst crushers are widely used as key equipment.

[0003] Most existing catalyst crushers use mechanical forces such as compression, shearing, or impact to pulverize materials through a crushing structure located inside the casing. However, during the crushing process, especially for certain catalysts with a certain degree of viscosity or moisture, the fragments and powders tend to adhere to the moving parts or outer wall of the crushing structure.

[0004] As the equipment operates for extended periods, these attached material residues accumulate and thicken, easily causing blockages in the crushing structure, significantly reducing crushing efficiency, and affecting the uniformity of the output. Currently, the common approach to address this issue is to periodically shut down the machine for manual cleaning and maintenance by operators. This method severely disrupts production continuity, increases labor intensity and maintenance costs, and makes it difficult to guarantee timely cleaning, resulting in low levels of automation and operational stability of the equipment.

[0005] Therefore, this invention proposes a catalyst crusher to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a catalyst crusher, which aims to improve the problem in the prior art where material residue easily adheres to the outer wall of the crushing structure, causing blockage and requiring manual cleaning during shutdown, thus affecting the continuity of production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a catalyst crusher, comprising a shell, a feed plate, and a crushing structure; and an adjustment component; The feed plate is fixedly connected to the top of the outer shell, and the crushing structure is disposed inside the outer shell and located below the feed plate; The adjustment component is disposed on the outside of the fracture structure; The adjustment assembly includes a hollow column as a guide rail, a connecting column, and a sliding ring. The connecting column and the sliding ring are slidably connected to the inner wall of the hollow column. A cleaning brush is fixedly connected to the first end of the connecting column through a connecting frame. The cleaning brush elastically abuts against the outer wall of the broken structure. A baffle is fixedly connected to the second end of the connecting column. A spring is disposed between the sliding ring and the connecting column. Preferably, the spring is sleeved around the outer periphery of the connecting post, and the two ends of the spring respectively abut against an annular protrusion formed on the sliding ring and the connecting post; Preferably, the baffle is positioned such that when the connecting column slides to the end of the preset stroke, the baffle abuts against the end face of the hollow column; Preferably, the catalyst crusher further includes a screening assembly disposed below the crushing structure; Preferably, the screening assembly includes a motor and an eccentric plate that is driven to rotate by the motor via a belt drive structure; Preferably, the screening assembly further includes a rotating plate and a connecting plate, wherein the side wall of the eccentric plate is rotatably connected to the rotating plate, and the side wall of the rotating plate is rotatably connected to the connecting plate; Preferably, the screening assembly further includes a screening screen, which is fixedly connected to the side wall of the connecting plate; Preferably, the screening assembly further includes a rotating wheel and a limiting rail, with the rotating wheel fixedly connected to the bottom of the screening screen, and the rotating wheel rollingly engaging with the inside of the limiting rail.

[0008] This utility model has the following beneficial effects: 1. This utility model, by setting an adjustment component, including a connecting column that cooperates with the crushing structure to achieve reciprocating sliding, a cleaning brush fixed on the connecting column, and a spring that provides elasticity, solves the problem in the prior art where material residue easily adheres to the outer wall of the crushing structure during operation, causing blockage and requiring manual cleaning after shutdown. It achieves the effect of automatically cleaning the outer wall of the crushing structure while the equipment is running, preventing blockage, ensuring crushing efficiency and long-term stable operation of the equipment, and reducing manual maintenance costs.

[0010] 3. This utility model achieves a simple and compact cleaning mechanism structure and convenient installation by setting the connecting column and sliding ring of the adjusting component to slide inside the hollow column, and using a spring to provide elastic pressure between the sliding ring and the connecting column.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5 The present invention provides an embodiment of a catalyst crusher, comprising a shell 2, a feed plate 1, a crushing structure 3 and an adjusting component 4. The feed plate 1 is fixedly connected to the top of the shell 2, the crushing structure 3 is disposed inside the shell 2 and located below the feed plate 1, and the adjusting component 4 is disposed on the outside of the crushing structure 3 for cleaning the outer wall of the crushing structure 3. Specifically, the adjustment component 4 includes a hollow column 401 serving as a guide rail, a connecting column 405, and a sliding ring 402. Both the connecting column 405 and the sliding ring 402 are slidably connected to the hollow column 403. A spring 404 is disposed between the sliding ring 402 and the connecting column 405. The spring 404 provides continuous contact pressure for the cleaning brush 407 to ensure cleaning effect. To achieve automatic cleaning, a drive cam is provided on the crushing structure 3, and a driven structure that is driven and cooperates with the drive cam is provided on the connecting column 405. When the crushing structure 3 is running, the cooperation between the drive cam and the driven structure can drive the connecting column 405 to slide back and forth in the hollow column 401, thereby driving the cleaning brush 407 to clean the outer wall of the crushing structure 3 back and forth to prevent material adhesion. The adjusting component 4 specifically includes a hollow column 401 serving as a guide rail, and a connecting column 405 and a sliding ring 402 slidably connected to the inner wall of the hollow column 401. A cleaning brush 407 is fixedly connected to the first end of the connecting column 405 via a connecting frame 406, and a baffle 403 is fixedly connected to the second end of the connecting column 405. A spring 404 is disposed between the sliding ring 402 and the connecting column 405, so that the cleaning brush 407 elastically abuts against the outer wall of the crushing structure 3. A driving cam is formed on the crushing structure 3, and a driven structure that drives the connecting column 405 to reciprocate within the inner cavity of the hollow column 401 through meshing with the driven structure. Spring 404 is sleeved around the outer periphery of connecting post 405. One end of spring 404 abuts against the end face of sliding ring 402, and the other end of spring 404 abuts against an annular protrusion formed on connecting post 405. The annular protrusion provides a stable support surface for the axial installation of spring 404. Baffle 403 is fixedly connected to the second end of connecting post 405. The radial dimension of baffle 403 is larger than the inner diameter of hollow post 401. When connecting post 405 slides to the end of the preset stroke, the inner side of baffle 403 abuts against the end face of hollow post 401, thereby structurally limiting the maximum sliding stroke of connecting post 405. The screening assembly 5 includes a motor 501 and an eccentric plate 503 driven to rotate by the motor 501 through a belt drive structure 502. To convert the rotational motion of the eccentric plate 503 into the reciprocating vibration of the screening assembly 5, the screening assembly 5 also includes a rotating plate 504 and a connecting plate 505. The rotating plate 504 is rotatably connected to the side wall of the eccentric plate 503, and the connecting plate 505 is rotatably connected to the side wall of the rotating plate 504. The screening assembly 5 also includes a screening screen 506, which is fixedly connected to the side wall of the connecting plate 505 for screening the crushed material. To ensure the stability and guidance of the movement of the screening screen 506, a rotating wheel 507 is fixedly connected to the bottom of the screening screen 506. The screening assembly 5 also includes a limiting rail 508, in which the rotating wheel 507 rolls within the limiting rail 508.

[0015] Working principle: The material enters the crushing structure 3 inside the outer shell 2 through the feed plate 1 for crushing. While the crushing structure 3 is running, the drive cam set on the crushing structure 3 rotates accordingly. The drive cam is in transmission cooperation with the driven structure on the connecting column 405 in the adjustment component 4, thereby driving the connecting column 405 to slide back and forth on the inner wall of the hollow column 401, which serves as a guide rail. The crushing structure consists of 3 pairs. The maximum size of a single nickel-aluminum alloy catalyst is ≤50mm×50mm×50mm, and the minimum size is ≥5mm×5mm×5mm. The catalyst is screened by the crusher. If the size is too small, it will easily lead to uneven feed flow rate and affect crushing efficiency. At the same time, the particle size of the copper catalyst is ≥1mm, and the maximum particle size is ≤10mm. If it exceeds 10mm, it will easily lead to uneven force during crushing and over-crushing. Screening component 5: Nickel-aluminum alloy series catalysts, after crushing, have no particles larger than 5mm to avoid exceeding the feed requirements of the activation equipment, and no fine powder with a particle size of <0.1mm to reduce powder loss during activation and reduce raw material loss; Copper-based catalysts, fine grade 0.5-1.5mm is flaked into 10-30 mesh, and coarse grade 1.5-3mm is pre-mixed. When the connecting column 405 slides, it drives the cleaning brush 407, which is fixedly connected to the first end of the connecting column 405 through the connecting frame 406, to reciprocate synchronously. The spring 404, which is set between the sliding ring 402 and the connecting column 405, always provides axial thrust to the connecting column 405, so that the cleaning brush 407 elastically abuts against the outer wall of the crushing structure 3, thereby realizing real-time automatic cleaning of the outer wall of the crushing structure 3 and preventing material adhesion and blockage. When the connecting column 405 slides to the end of the preset stroke, the baffle 403 at the second end of the connecting column 405 abuts against the end face of the hollow column 401, which plays a limiting role. The crushed material falls into the screening assembly 5 below under the action of gravity; the motor 501 of the screening assembly 5 starts and drives the eccentric plate 503 to rotate through the belt drive structure 502; the eccentric plate 503 converts the rotational motion into the reciprocating vibration of the screening screen 506 fixedly connected to the connecting plate 505 through the rotating plate 504 and the connecting plate 505; the rotating wheel 507 at the bottom of the screening screen 506 rolls and cooperates inside the limiting rail 508, providing support and guidance for the smooth movement of the screening screen 506, and finally achieving efficient screening of the crushed material.
