[0002] When coke is transported and discharged in the smelting industry, since coking coal contains a certain amount of coal ash, a certain amount of dust will be emitted when loading, which will pollute the environment in the workshop. In order to reduce the pollution in the workshop, dust collection ducts are usually installed on the top of the workshop. The dust collection ducts are connected to the main pipeline of the dust removal station, so the scattered dust can be captured, and then the dust is collected into the ash bin of the dust removal station through the main pipeline of the dust removal station, thereby realizing the control of unorganized dust emissions.

[0003] In order to capture more dust in the prior art, the dust collection duct used in the workshop is usually large in size. When the collection duct needs to be installed in the workshop, it is inconvenient to move the duct into the workshop due to the large size of the duct.

[0004] To this end, we provide a device for dust collection to solve the above problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0032] See also Figure 1-7 The utility model is a device for collecting dust, comprising a first air cylinder 1, the left surface of which is movably connected to two second air cylinders 2, the first air cylinder 1 is provided with an air receiving port 4, the two second air cylinders 2 are provided with a plurality of air inlets 5, the inner surface of the first air cylinder 1 is fixedly connected to two first sealing rings 6, the inner surfaces of the two second air cylinders 2 are fixedly connected to second sealing rings 7, and the left surfaces of the two first sealing rings 6 are in contact with the two second sealing rings 7 respectively.

[0033] The fixed structure 20 includes a slide 8, a limit rod 9, a T-block 10, a slider 11, a connecting rod 12, a connecting block 13, a threaded rod 14, a nut 15 and a positioning block 16. The side surface of the slide 8 is fixedly connected to the first air duct 1, the side surface of the limit rod 9 is fixedly connected to the slide 8, the inner surface of the T-block 10 is slidably connected to the limit rod 9, the side surface of the slider 11 is fixedly connected to the T-block 10, the side surface of the connecting rod 12 is fixedly connected to the slider 11, the inner surface of the connecting block 13 is rotatably connected to the connecting rod 12, the side surface of the threaded rod 14 is fixedly connected to the connecting block 13, the side surface of the positioning block 16 is fixedly connected to the second air duct 2, the inner surface of the nut 15 is threadedly connected to the threaded rod 14, and the outer surface of the threaded rod 14 is movably connected to the positioning block 16.

[0034] Specifically, one end of the connecting rod 12 away from the slider 11 is fixedly connected with an anti-slip block 17, and the side surface of the anti-slip block 17 contacts the connecting block 13. The outer surface of the limit rod 9 is slidably sleeved with a spring 18, and one end of the spring 18 is fixedly connected to the side surface of the T-block 10. The end of the spring 18 away from the T-block 10 is fixedly connected to the side inner wall of the slideway 8. The slideway 8 is provided with a slide groove 19, and the outer surface of the T-block 10 is slidably connected to the slide groove 19. The positioning block 16 is provided with a positioning groove 3, and the outer surface of the threaded rod 14 is movably connected to the positioning groove 3. Under the action of the spring 18, the threaded rod 14 can be quickly inserted into the positioning groove 3, and the movement distance and direction of the T-block 10 can be limited by the setting of the slide groove 19. Specific embodiment 2

[0036] See also Figure 1-7On the basis of the specific embodiment 1, the limiting rod 9 passes through the T-block 10, the connecting rod 12 passes through the connecting block 13, the threaded rod 14 passes through the nut 15 and the positioning block 16 respectively, the right surface of the nut 15 contacts the positioning block 16, the side surface of the connecting block 13 contacts the slider 11, and the number of the fixing structures 20 is multiple.

[0037] Specifically, by setting the limit rod 9, the T-block 10 can only move in the horizontal direction. At the same time, when the nut 15 contacts the positioning block 16, the threaded rod 14 can be fixed, and the connection and fixation between the first wind tube 1 and the second wind tube 2 can be completed through the fixing structure 20, and it is also convenient to separate the first wind tube 1 and the second wind tube 2.

[0038] The working principle of the utility model is as follows: by rotating the nut 15, the nut 15 can be removed from the threaded rod 14, thereby releasing the fixation of the threaded rod 14, and then pulling the connecting block 13, so that the movable connecting block 13 can drive the threaded rod 14, the connecting rod 12, the slider 11, and the anti-dropping block 17 to move, so that the movable slider 11 can drive the T-block 10 to move horizontally on the limiting rod 9, and at the same time, the moving T-block 10 will squeeze the spring 18 on the slideway 8, so that the spring 18 is in a taut state, and when the moved threaded rod 14 is disengaged from the positioning groove 3 on the positioning block 16, the connection between the first air duct 1 and the second air duct 2 can be released, so that the first air duct 1 and the second air duct 2 can be connected. The air ducts 2 are separated, and then the connecting block 13 is flipped over so that the connecting block 13 and the threaded rod 14 can be flipped over with the connecting rod 12 as the central axis. At the same time, under the action of the anti-dropping block 17, the connecting block 13 will not be detached from the connecting rod 12. When the flipped threaded rod 14 no longer corresponds to the positioning groove 3, the pulled connecting block 13 is released, so that the spring 18 is no longer restricted by the tension and rebounds, and then the rebounding spring 18 drives the T-block 10, the slider 11, the connecting rod 12, the connecting block 13, the threaded rod 14 and the anti-dropping block 17 to move. Because the threaded rod 14 no longer corresponds to the positioning groove 3, the threaded rod 14 will not be inserted into the positioning groove 3. After the first air duct 1 and the second air duct 2 are separated, the device can be reduced. The overall area of ​​the device is convenient for moving. When the first air duct 1 and the second air duct 2 are moved to the workshop where they need to be installed, the first air duct 1 is brought into contact with the second air duct 2, and the first sealing ring 6 is brought into contact with the second sealing ring 7. Then the connecting block 13 is pulled to make the moving connecting block 13 drive the T-block 10, the slider 11, the connecting rod 12, the connecting block 13, the threaded rod 14 and the anti-slip block 17 to move while keeping the spring 18 in a tightened state. When the moved threaded rod 14 is not affected by the nut 15 when flipping, the connecting block 13 is flipped in the opposite direction so that the flipped connecting block 13 drives the threaded rod 14 to flip. When the flipped connecting block 13 corresponds to the positioning groove 3, the pulled connecting block 13 is released. The spring 18 is no longer restricted by the tension and rebounds, so that the rebounding spring 18 drives the T-block 10, the slider 11, the connecting rod 12, the connecting block 13, the threaded rod 14 and the anti-slip block 17 to move to reset. When the moved threaded rod 14 is inserted into the positioning groove 3, the nut 15 is screwed back onto the threaded rod 14. When the nut 15 contacts the T-block 10, the rotation of the nut 15 is stopped, thereby fixing the threaded rod 14 and completing the connection and fixation between the first air duct 1 and the second air duct 2 at the same time. Under the action of the first sealing ring 6 and the second sealing ring 7, the sealing effect between the first air duct 1 and the second air duct 2 can be improved to prevent dust from leaking into the outside air through the gap between the first air duct 1 and the second air duct 2.
