Description

Technical Field

[0001] This utility model provides a screen replacement device for a gyratory screen, belonging to the technical field of gyratory screen equipment. Background Technology

[0002] The gyratory screen, a highly efficient screening device, is widely used in industries such as chemical, food, and mining. It achieves material classification and screening by using a vibrating motor to drive the screen body to gyrate. As the core component of the gyratory screen, the screen mesh is prone to wear and clogging during long-term use, requiring regular replacement.

[0003] Based on the above, the inventors discovered that:

[0004] Existing gyratory screens typically use bolts to directly fix the screen mesh to the screen body. Replacing the mesh requires removing multiple bolts, making the process cumbersome, time-consuming, and inconvenient for assembling and disassembling the screen. Furthermore, if only a limiting device is used to control the screen mesh, it may detach during the gyratory process, indicating that the screen mesh is not securely fixed.

[0005] Therefore, in view of this, the existing structure was studied and improved, and a screen replacement device for a swing screen was proposed to solve the above-mentioned problems. Utility Model Content

[0006] The technical problem this invention aims to solve is that the traditional screen replacement device for a gyratory screen is inconvenient to assemble and disassemble for screen replacement, and the screen is not fixed stably.

[0007] To solve the above problems, the present invention proposes the following technical solution: a screen replacement device for a gyratory screen, comprising a gyratory screen body, wherein a screen replacement assembly is provided on the gyratory screen body and the screen replacement assembly includes a screen, a fixing plate, a limiting plate, a spring assembly, and a mounting plate, wherein the limiting plate is used for limiting the screen.

[0008] Furthermore, a placement platform is provided on the inner side of the oscillating screen body, and the screen is placed on the placement platform.

[0009] Furthermore, the gyratory screen body has an internal cavity and a limiting plate is placed inside the cavity. The other end of the gyratory screen body extends to the outside of the gyratory screen body, and the spring assembly is placed between the limiting plate and the inner wall of the cavity and fixedly connected to it.

[0010] Furthermore, the fixing plate has a U-shaped structure and is placed at the lower end of the screen and fixedly connected to it. The fixing plate is placed on the limiting plate and the protrusion of the limiting plate is placed in the through groove of the fixing plate.

[0011] Furthermore, the mounting plate is placed on the outside of the gyratory screen body and fixedly connected to it, and the mounting plate is placed below and close to the limiting plate.

[0012] Furthermore, the limiting plate and the mounting plate are respectively provided with through holes, and threaded rods are inserted through the through holes. Each stage of the oscillating screen is threaded with a nut on the threaded rod.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the screen replacement device for a gyratory screen of this utility model are as follows:

[0014] 1. This utility model, through the cooperation structure of the limiting plate, threaded rod, and nut, allows for the disassembly of each stage of the swing screen body. With the addition of a screen replacement component, it facilitates the assembly, disassembly, and replacement of the screen.

[0015] 2. This utility model has a through hole on the limiting plate, which indirectly fixes the screen in a secondary manner when the whole is fixed with bolts, so that the screen is firmly fixed. Attached Figure Description

[0024] 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.

[0025] The technical background of this application fully explains the problems of the prior art, and there are no overarching or general issues. The following utility model content and specific embodiments describe in detail the problems that this application needs to solve, clarify the technical problems that the technical solution needs to solve, and determine that the technical solution of this application has beneficial effects compared with the objective prior art.

[0026] Please see Figure 1-5 As shown: This utility model provides a screen replacement device for a gyratory screen: it includes a gyratory screen body 1, and a screen replacement assembly is provided on the gyratory screen body 1. The screen replacement assembly includes a screen 2, a fixing plate 3, a limiting plate 4, a spring assembly 5, and a mounting plate 6. The limiting plate 4 is used to limit the screen 2.

[0027] The fixing plate 3 has a U-shaped structure and is placed at the lower end of the screen 2 and fixedly connected to it. The fixing plate 3 is placed on the limiting plate 4 and the protrusion 9 of the limiting plate 4 is placed in the through groove 10 of the fixing plate 3. Through the cooperation of the protrusion 12 and the through groove 13, the screen 5 is accurately positioned to prevent the screen 5 from shifting during operation.

[0028] like Figure 5 As shown, a placement platform 7 is provided on the inner side of the swing screen body 1 and the screen 2 is placed on the placement platform 7.

[0029] The gyratory screen body 1 has a cavity 8 inside and a limiting plate 4 is placed inside the cavity 8. The other end of the gyratory screen body 1 extends to the outside of the gyratory screen body 1. The spring assembly 5 is placed between the limiting plate 4 and the inner wall of the cavity 8 and is fixedly connected to it.

[0030] The mounting plate 6 is placed on the outside of the gyratory screen body 1 and fixedly connected to it. The mounting plate 6 is placed below the limiting plate 4 and close to it.

[0031] The limiting plate 4 and the mounting plate 6 are respectively provided with through holes, and threaded rods 11 are inserted through the through holes. Nuts 12 are threadedly connected to each stage of the oscillating screen and located on the threaded rods 11.

[0032] The principle of the screen replacement device for a gyratory screen of this utility model is as follows:

[0033] Place the screen on the placement platform, insert the fixing plate into the cavity, and simultaneously press the limiting plate to compress the spring assembly within the cavity. Release the limiting plate, and under the action of the spring assembly, the screen will protrude and be positioned within the through groove, thus limiting its position. The gyratory screen body is a three-stage screening unit. The mounting plate is fixedly connected to the outer surface of the next-stage gyratory screen body. The three stages of screening are stacked vertically. Figure 1 , 2 As shown, insert the bolt rod into the through hole and secure it with a nut.

[0034] This invention facilitates the assembly, disassembly, and replacement of the screen by incorporating a screen replacement component, while ensuring the screen is securely fixed.
