Description

Technical Field

[0001] This utility model relates to the field of refractory material screening and processing technology, specifically to an easy-to-clean, anti-clogging cylindrical screen. Background Technology

[0002] As a key screening device in refractory material production, the cylindrical screen is mainly used for particle size classification of sintered refractory raw materials such as bauxite, magnesia, and corundum. Because refractory raw materials are typically hard, have irregular particle shapes, and are prone to dust and fine particle adhesion during production, material embedding and clogging frequently occur on the screen surface. This is especially true when processing refractory raw materials that have undergone high-temperature treatment and still retain a certain temperature with a high concentration of surface powder; fine particles are more easily adhered to the screen surface under the influence of electrostatics and surface tension, gradually forming blockages and significantly reducing screening efficiency.

[0003] Currently, the refractory materials industry typically addresses the problem of cylindrical screen blockage by using vibratory screen cleaning devices or periodic manual cleaning. However, vibratory screen cleaning can easily lead to screen structure fatigue during long-term operation, affecting equipment lifespan; while manual cleaning requires frequent shutdowns, which not only reduces equipment utilization but also poses safety hazards when cleaning high-temperature materials.

[0004] In the prior art, patent document CN219597242U discloses an anti-clogging cylindrical screen, including a cleaning mechanism. The cleaning mechanism comprises cleaning rollers, a meshing gear, a cam, a base, and a transmission assembly. Two cleaning rollers are located inside the screening mechanism, with their ends slidably connected to the base. The meshing gear and the cam are located on the cleaning rollers, with the meshing gear inside the screening mechanism and the cam outside. A protrusion for pushing the cam is provided at the upper end of the base. The rotational motion of the cleaning rollers needs to be converted into axial reciprocating motion via a cam mechanism. This mechanism includes multiple precision-fitting parts such as the cam, protrusion, and groove, resulting in a complex structure that is prone to jamming in dusty environments and is difficult to implement as an improvement on existing cylindrical screen structures. Utility Model Content

[0005] This invention provides an easy-to-clean, anti-clogging cylindrical screen to solve the technical problems in the prior art, such as the easy clogging of the screen when screening fine and sticky materials, and the low efficiency and poor effect of traditional cleaning methods, which seriously affect the screening efficiency.

[0006] To solve the above problems, the present invention provides an easy-to-clean, anti-clogging cylindrical screen using the following technical solution: The device includes a support frame assembly and a cylinder fixedly mounted on the support frame assembly. A cylindrical screen is rotatably mounted inside the cylinder. One end of the cylindrical screen is equipped with a power mechanism for driving air rotation. The bottom end of the cylinder is equipped with a feeding section. The cylinder has an arc-shaped reinforcing section. The top of the arc-shaped reinforcing section is equipped with a spray pipe structure for cleaning the cylindrical screen. One side of the arc-shaped reinforcing section is equipped with a maintenance window. The inner wall of the cylinder is detachably equipped with a brush structure near the maintenance window and below the maintenance window. The brush structure consists of two sections distributed from left to right, and the brush structures at both ends are staggered vertically.

[0007] Furthermore, the nozzle structure includes a horizontal tube disposed along the axial direction of the cylinder near the upper end of the arc-shaped reinforcing part, and the cylinder wall is provided with a spray hole communicating with the horizontal tube, wherein the spray hole is a plurality of holes arranged at intervals along the axial direction of the horizontal tube.

[0008] Furthermore, the ejector hole is inclined from top to bottom from one end near the horizontal tube to the other end, and the angle α between the central axis of the ejector hole and the horizontal line is 30°-45°.

[0009] Furthermore, the brush structure includes a T-shaped groove rail disposed on the inner wall of the cylinder. The T-shaped groove rail consists of two sections that are staggered vertically. Each section of the T-shaped groove rail is fitted with a brush plate, and the brush plate includes a T-shaped slider that cooperates with the T-shaped groove rail.

[0010] Furthermore, each T-shaped groove contains n brush plates arranged in an abutting pattern, where n ≥ 2.

[0011] Furthermore, a U-shaped clip is provided below the T-shaped slider of the brush plate at the end for locking onto the T-shaped groove rail.

[0012] Furthermore, a lifting lug is provided on the upper end face of the arc-shaped reinforcing part.

[0013] The beneficial effects of the easy-to-clean, anti-clogging cylindrical screen provided by this utility model are: 1. In this invention, the brush plate of the brush structure remains in constant contact with the outside of the cylindrical screen during its rotation. This allows for timely brushing of materials adhering to the screen mesh, preventing material accumulation and blockage, ensuring the normal operation of the cylindrical screen, and extending the equipment's service life. When the cylindrical screen requires cleaning, high-pressure water can be sprayed through the nozzles, working in conjunction with the brush plate's sweeping action to thoroughly remove materials and dirt from the screen. The combination of the impact force of the high-pressure water and the mechanical brushing force of the brush plate achieves highly efficient cleaning, reducing the workload and difficulty of manual cleaning.

[0014] 2. The brush structure in this utility model adopts a modular design, with two staggered T-shaped grooves. Each section contains multiple short brush plates arranged in an abutting pattern. The brush plates engage with the T-shaped grooves via T-shaped sliders. This eliminates the need for complex operations and numerous auxiliary tools during brush plate installation and replacement; installation or removal is simply a matter of sliding the brush plates from the ends, greatly improving installation and replacement efficiency and reducing maintenance costs.

[0015] 3. In this utility model, the nozzles on the inner wall of the cylinder, which communicate with the horizontal pipe, are arranged at intervals along the axial direction of the horizontal pipe and slope downwards, with the angle α between the central axis and the horizontal line being 30°-45°. This not only facilitates the installation of the horizontal pipe on the arc-shaped reinforcing part, but also ensures that the nozzle outlet points obliquely downwards, effectively preventing materials, dust, etc. from entering the nozzle outlet and causing blockage, thus guaranteeing the smooth flow of the nozzle structure when high-pressure gas or high-pressure water is introduced for auxiliary cleaning.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0020] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0021] An embodiment of an easy-to-clean, anti-clogging cylindrical screen provided by this utility model: like Figures 1 to 5 As shown, The system includes a support frame assembly 1 and a cylinder 2 fixedly mounted on the support frame assembly 1. A cylindrical screen 3 is rotatably mounted inside the cylinder 2. One end of the cylindrical screen 3 is equipped with a power mechanism for driving air rotation, and the bottom end of the cylinder 2 is equipped with a discharge section 21. Each end of the cylindrical screen 3 is equipped with a circular plate that is rotatably supported by the cylinder 2. One of the circular plates is equipped with a support shaft, which is rotatably supported by a bushing on the support frame assembly 1. The free end of the support shaft is equipped with a flange that connects to the power mechanism, i.e., a motor. The other circular plate is equipped with a feed inlet, which is bolted to a baffle. Below the feed inlet is a discharge outlet, which is also equipped with a baffle.

[0022] In this embodiment, the arc-shaped reinforcing part 22 of the cylinder 2 and the top of the arc-shaped reinforcing part 22 are provided with a spray pipe structure for cleaning the cylindrical screen 3.

[0023] The nozzle structure includes a horizontal tube 25 located near the upper end of the arc-shaped reinforcing part 22 along the axial direction of the cylinder 2. The cylinder wall of the cylinder 2 is provided with a spray hole 26 communicating with the horizontal tube 25. The spray hole 26 is a plurality of holes arranged at intervals along the axial direction of the horizontal tube 25.

[0024] The nozzle 26 is inclined from top to bottom from one end near the horizontal tube 25 to the other end, and the angle α between the central axis of the nozzle 26 and the horizontal line is 30°.

[0025] By setting the nozzle 26, high-pressure gas or high-pressure water can be introduced to assist in cleaning. The nozzle 26 is set at an angle so that its outlet points diagonally downwards to prevent materials, dust, etc. from entering and causing blockage at the outlet.

[0026] In this embodiment, an inspection window 23 is provided on one side of the arc-shaped reinforcing part 22. A brush structure 24 is detachably provided on the inner wall of the cylinder 2 near the inspection window 23 and below the inspection window 23. The brush structure 24 consists of two segments distributed left and right, and the brush structures 24 at both ends are staggered vertically.

[0027] The brush structure 24 includes a T-shaped groove 241 on the inner wall of the cylinder 2. The T-shaped groove 241 consists of two sections that are staggered vertically. Each section of the T-shaped groove 241 is equipped with a brush plate 242. The brush plate 242 includes a T-shaped slider 243 that cooperates with the T-shaped groove 241.

[0028] The T-shaped rails 241 are segmented and staggered, facilitating operation at the inspection window and allowing the brush plates 242 to be slidably installed from the ends. When the brush plates 242 become worn or damaged and need replacement, the operator simply slides the damaged brush plate 242 out of the T-shaped rails 241 through the inspection window 23 and then installs a new brush plate 242.

[0029] In each section of the T-shaped groove rail 241, there are multiple brush plates 242 arranged in abutting arrangement.

[0030] The T-slot rail 241 contains multiple shorter brush plates 242 to avoid interference when sliding in from the end, which could occur with longer brush plates. The shorter brush plates 242 offer greater operational flexibility, allowing workers to more easily control their installation position and orientation. Sliding the brush plates 242 into the T-slot rail 241 requires no complex operating skills or numerous auxiliary tools; installation is completed simply by pushing the brush plates 242 to make contact with other brush plates 242.

[0031] Among them, the brush plate 242 at the end has a U-shaped clip 244 below the T-shaped slider 243 for locking onto the T-shaped groove rail 241.

[0032] By setting a U-shaped clip 244, one end of the brush plate 242 is fastened to the T-shaped groove rail 241, and the other end of the brush plate 242 abuts against the adjacent circular plate.

[0033] In this embodiment, a lifting lug 221 is provided on the upper end surface of the arc-shaped reinforcing part 22. The structure of the lifting lug 221 facilitates the lifting of the mobile equipment.

[0034] In practical use, the easy-to-clean, anti-clogging cylindrical screen of this utility model is used by placing the material to be screened through the feed inlet, then sealing the corresponding baffle, and the screening is achieved by the rotation of the cylindrical screen 3. The material that meets the particle size requirements is discharged through the discharge part 21, while the material that does not meet the particle size requirements will remain in the cylindrical screen 3 and finally be discharged from the discharge port.

[0035] During the rotary screening process, the brush plate 242 is used on the outside of the cylindrical screen 3 to help prevent clogging. When the cylindrical screen 3 needs cleaning, high-pressure water can be sprayed through the spray hole 26, which, together with the brush plate 242, achieves efficient cleaning.
