Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, and in particular to a blocking mechanism that can change the feed path of a vibrating screen. Background Technology
[0002] The coal and water in the mine exhibit a gel-like form, which greatly hinders the screening process. The fundamental reason is that the coal particles are extremely small, resulting in a huge specific surface area. When water is present, according to the principle of van der Waals forces, the particles attract each other. Water molecules act as a medium, adsorbing onto the particle surface and significantly reducing the distance between particles. Even though lump coal and gangue have relatively rough surfaces, they are still subject to this force. Once coal powder adheres to the surface of lump coal and gangue, it gradually forms a gel-like form over time and through material interactions.
[0003] The working principle of a vibrating screen is to use vibration to cause the material to stratify and pass through the screen. However, when faced with this kind of colloidal material, due to its strong internal cohesion, the vibration energy provided by the vibrating screen is difficult to overcome these cohesions. This makes it difficult to fully disperse and smoothly screen the mixture of colloidal water, coal powder, lump coal and gangue during actual operation. Therefore, this solution proposes a blocking mechanism that can change the feed path of the vibrating screen to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a blocking mechanism that can change the feed path of a vibrating screen, so as to solve the problems mentioned in the background art.

[0006] Threaded steel bar, which is disposed on the top of the screen plate, is used to block the path of the material;
[0007] A support assembly is disposed at the bottom of the rebar and is used to support the rebar.

[0017] The technical effects and advantages of this utility model are as follows:

[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] This utility model provides, for example Figure 1-4 A blocking mechanism that can change the feed path of a vibrating screen, shown, is installed on the screen plate 1 and includes:
[0026] Threaded steel bar 2 is set on top of screen plate 1 and is used to block the path of material.
[0027] Support component 3 is set at the bottom of the threaded steel bar 2 and is used to support the threaded steel bar 2;
[0028] Fixing component 4 is located at the connection between support component 3 and sieve plate 1, and is used to fix the position of support component 3;
[0029] Reinforcing component 5 is installed at the connection between support component 3 and screen plate 1, and is used to strengthen the connection between support component 3 and screen plate 1.
[0030] It should be noted that the screen plate 1 has multiple screen holes. The screen plate 1 is installed on the vibrating screen. During use, the vibrating screen drives the screen plate 1 to vibrate and screen the material on the top of the screen plate 1. The threaded steel bar 2 is a cylindrical steel bar with a spiral shape on its surface. The threaded steel bar 2 is fixed to the top of the screen plate 1 at a specific spacing and arrangement by the fixing component 4 and the support component 3. Its protruding part is in direct contact with the material, which increases the friction with the colloidal coal and water and increases the number of times the material tumbles. In each tumbling process, the coal and water mixture can receive the vibration action applied by the vibrating screen more comprehensively and fully, thereby screening the coal and water mixture.
[0031] Specifically, support component 3 includes:
[0032] Support block 301 is set on the top of sieve plate 1;
[0033] Support groove 302 is opened on the top of screen plate 1. The horizontal longitudinal section of support groove 302 is set as arc. Threaded steel bar 2 is inserted and connected inside support groove 302.
[0034] It should be noted that the arc-shaped support groove 302 is adapted to the outer wall of the threaded steel bar 2. When it is necessary to fix the threaded steel bar 2 to the top of the screen plate 1, the threaded steel bar 2 is first placed inside the support groove 302 and fixed inside the support groove 302 by welding. The ground of the support block 301 is flat to avoid the threaded steel bar 2 from rolling randomly on the top of the screen plate 1 when it is installed.
[0035] Specifically, the fixing component 4 includes an insert block 402 fixedly connected to the bottom end of the support block 301. The top of the screen plate 1 is provided with a through slot 401. The insert block 402 is inserted into the inside of the through slot 401. The bottom end of the insert block 402 is fixedly connected with a threaded rod 405. The middle part of the threaded rod 405 is threaded with a nut 404 for fixing the position of the support block 301. A sealing gasket 403 is provided on the side of the screen plate 1 opposite to the nut 404. The sealing gasket 403 is sleeved on the top of the threaded rod 405.
[0036] It should be noted that the sealing gasket 403 is a flexible material used to fill the gap between the nut 404 and the screen plate 1, which serves to reduce shock and seal. The insert block 402 is adapted to the slot 401. When it is necessary to fix the position of the support block 301, the insert block 402 is first inserted into the slot 401 on the screen plate 1, then the sealing gasket 403 is fitted onto the bottom of the threaded rod 405, and the nut 404 is threaded onto the bottom of the threaded rod 405. The position of the support block 301 is then fixed by the nut 404.
[0037] Specifically, the reinforcing component 5 includes a reinforcing block 501 fixedly connected to the bottom of the support block 301, and a reinforcing groove 502 is provided at the top of the sieve plate 1, with the reinforcing block 501 inserted into the interior of the reinforcing groove 502.
[0038] It should be noted that the number of reinforcing blocks 501 is at least two, and the number of reinforcing grooves 502 is the same as the number of reinforcing blocks 501. Then, the support block 301 is placed on top of the screen plate 1, and the reinforcing blocks 501 at the bottom of the support block 301 are inserted into the interior of the reinforcing grooves 502. The connection between the screen plate 1 and the support block 301 is strengthened by the reinforcing blocks 501 and the reinforcing grooves 502.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
