Description

Technical Field

[0001] This utility model relates to the field of mining valve technology, and in particular to a mining valve with a dust removal structure. Background Technology

[0002] Existing mining valves have an opening on the side, in which a gate is movably installed. The surface of the gate is sealed to the opening by a sealing structure, such as a rubber block. However, during the movement of the gate, the material on the surface of the gate can easily rub against the rubber block, causing wear and tear on the sealing structure. After prolonged use, gaps will appear between the sealing structure and the surface of the gate, allowing dust to easily fly out through the gaps and accumulate on the screw surface. In severe cases, this can even cause the screw to jam, increasing the difficulty of manually turning the screw.

[0003] A search revealed a Chinese utility model patent with application number 202220755497.8, which describes a two-way valve design for mining. The design involves loosening the fixing bolts, sliding the slider, and using the meshing teeth on the scraper to remove dust from the screw to the collection box. However, this solution is more of a post-cleaning measure and does not fundamentally prevent the dust from adhering to its source.

[0004] In view of this, this utility model proposes a mining valve with a dust removal structure, which aims to prevent dust from directly contacting the screw at the source. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mining valve with a dust removal structure to solve the above problems.

[0006] To achieve the above objectives, this utility model provides a mining valve with a dust removal structure, comprising a valve body, an opening on the side of the valve body, a gate plate slidably disposed within the opening, a screw drive mechanism connected to the gate plate, a dust cover fixedly disposed on the side of the valve body, the gate plate and the drive mechanism being movably disposed within the dust cover, a baffle plate fixedly disposed on the upper surface of the end of the gate plate away from the valve body, when the gate plate is closed, the baffle plate is located outside the valve body, and the gate plate, the baffle plate, the top of the dust cover and the side of the valve body constitute a closed cavity.

[0007] Preferably, a dust suction mechanism is fixedly installed on the top of the dust cover.

[0008] Preferably, the dust collection mechanism includes a vacuum cleaner fixed to the top of the dust cover, the vacuum cleaner's suction port is connected to a suction pipe, the lower end of the suction pipe extends into the interior of the dust cover, and the lower end of the suction pipe is disposed on the upper surface of the gate and located between the baffle and the valve body.

[0009] Preferably, a dust cover plate is rotatably mounted on the upper end of the dust cover via a rotating structure, and the vacuum cleaner is fixedly connected to the dust cover plate.

[0010] Preferably, guide rails are fixedly provided on both sides of the inner wall of the dust cover, and the gate is slidably installed in the guide rails.

[0011] Preferably, two rubber blocks are fixed at the upper and lower ends of the opening, and the two rubber blocks are in close contact with the upper and lower surfaces of the gate, respectively.

[0012] Preferably, the screw drive mechanism includes a threaded rod, one end of which is rotatably connected to the gate plate, and the other end of which is threadedly connected to the dust cover.

[0013] Preferably, a sealing block is fixed to the top of the baffle, and the sealing block slides in contact with the inner surface of the dust cover.

[0014] Compared with the prior art, this utility model has the following advantages: The mining valve with a dust removal structure of this utility model has a dust cover fixedly installed on the side of the valve body, completely enclosing the gate and screw drive mechanism to form a closed environment, preventing dust generated during material feeding from contacting the screw. In addition, a baffle is added to the end of the gate away from the valve body, and a sealing block is fixed to the top of the baffle, which slides in contact with the inner surface of the top of the dust cover. This isolates the dust carried out by the gate within the closed cavity formed by the gate, baffle, top of the dust cover, and side of the valve body, preventing dust from contacting the screw and further enhancing the dust-proof effect.

[0020] The following is in conjunction with the appendix Figures 1-3 The specific embodiments of this utility model will be described in further detail.

[0021] like Figures 1-3 As shown, this utility model discloses a mining valve with a dust removal structure, including a valve body 1. The side of the valve body 1 is provided with an opening 2. A gate 3 is slidably provided in the opening 2. The gate 3 is connected to a screw drive mechanism 4. In use, the screw drive mechanism 4 drives the gate 3 to move in the opening 2 to realize the opening and closing of the valve body 1. The above is the existing mining valve structure, which will not be described in detail here.

[0022] To prevent dust from flying up during material feeding from contacting the surface of the screw, a dust cover 5 is fixedly installed on the side of the valve body 1, and the gate plate 3 and the screw drive mechanism 4 are all movably installed inside the dust cover 5.

[0023] Furthermore, in order to prevent the material inside the valve body 1 from being carried out and falling onto the surface of the screw when the gate 3 moves, a baffle 6 is fixedly provided on the upper surface of the end of the gate 3 away from the valve body 1. When the gate 3 is closed, the baffle 6 is located on the outside of the valve body 1. In this way, even if material is carried out by the gate 3 from the opening 2 on the side of the valve body 1, it will be blocked by the baffle 6, thereby preventing the material from spilling onto the surface of the screw.

[0024] Additionally, please refer to Figure 3 A sealing block 7 is fixed to the top of the baffle 6. The sealing block 7 slides in contact with the inner surface of the top of the dust cover 5. It can be understood that since the sealing block 7 is set on the top of the baffle 6, even if material is carried out into the dust cover 5 because it is stuck to the surface of the gate 3, it is difficult to reach the space between the sealing block 7 and the top of the dust cover 5, thus avoiding severe wear on the sealing block 7 when it slides. This allows the sealing block 7 to maintain a tight seal with the dust cover 5, so that the dust is isolated in the closed cavity 100 formed by the gate 3, the baffle 6, the top of the dust cover 5 and the side of the valve body 1, preventing the dust from contacting the screw.

[0025] In some embodiments, a dust suction mechanism 8 is fixedly installed on the top of the dust cover 5.

[0026] The vacuuming mechanism 8 includes a vacuum cleaner 81 fixed to the top of the dust cover 5. The vacuum cleaner 81 has a vacuum nozzle connected to a vacuum pipe 82. The lower end of the vacuum pipe 82 extends into the interior of the dust cover 5. The lower end of the vacuum pipe 82 is located on the upper surface of the gate 3 and between the baffle 6 and the valve body 1. When cleaning the enclosed cavity 100, the external power supply of the vacuum cleaner 81 can be turned on, and the dust can be extracted through the vacuum pipe 82.

[0027] Furthermore, to facilitate cleaning the inside of the dust cover 5, a dust cover cover plate 10 is rotatably installed on the upper end of the dust cover 5 via a rotating structure 9. The vacuum cleaner 81 is fixedly connected to the dust cover cover plate 10. The dust cover cover plate 10 allows the dust cover 5 to be opened, facilitating cleaning of the screw and application of lubricating oil. When the dust cover cover plate 10 is closed, the sealing block 7 slides in contact with the inner surface of the dust cover cover plate 10 when the gate 3 moves.

[0028] The inner walls of the dust cover 5 are fixedly provided with guide rails 11 on both sides, and the gate 3 is slidably installed in the guide rails 11.

[0029] In some embodiments, two rubber blocks 12 are fixed at the upper and lower ends of the opening 2. The two rubber blocks 12 are in close contact with the upper and lower surfaces of the gate 3, respectively. The setting of the rubber blocks 12 increases the sealing effect between the gate 3 and the opening 2. In reality, the lower rubber block 12 wears more slowly, while the upper rubber block 12 wears more quickly because the surface of the gate 3 carries material, and the material will wear down the rubber block 12 when it moves. This results in gaps between the opening 2 and the surface of the gate 3, and the material is easy to leak through the gaps when feeding. It is precisely because of this kind of problem that this utility model can isolate the leaked material through the baffle and sealing block 7 to prevent the surface of the screw from being contaminated.

[0030] In some embodiments, the screw drive mechanism 4 includes a threaded rod 41, one end of which is rotatably connected to the gate plate 3, and the other end of which is threadedly connected to the dust cover 5. A handwheel is fixed to the threaded rod 41, and the threaded rod 41 can be rotated by manually turning the handwheel. When the threaded rod 41 rotates, it moves along the length of the dust cover 5, thereby moving the gate plate 3.

[0031] In summary, this utility model discloses a mining valve with a dust removal structure. A dust cover 5 is fixedly installed on the side of the valve body 1, completely enclosing the gate 3 and the screw drive mechanism 4 to form a closed environment, preventing dust generated during material feeding from contacting the threaded rod 41. In addition, a baffle 6 is added to the end of the gate 3 away from the valve body 1. A sealing block 7 is fixed to the top of the baffle 6 and slides in contact with the inner surface of the top of the dust cover 5. This isolates the dust carried out by the gate 3 within the closed cavity 100 formed by the gate 3, the baffle 6, the top of the dust cover 5, and the side of the valve body 1, preventing dust from contacting the threaded rod 41 and further enhancing the dust prevention effect.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
