[0002] With the continuous development of society and the continuous progress of technology, the technologies related to coke oven environmental protection dust removal are also continuously improving. The ground station of the stamping coke oven system uses a bag-type dust removal system to treat the dust of the coke oven. The smoke and dust emitted during the coal charging and coke pushing of the coke oven are collected by the fan of the ground dust removal station and filtered and purified in the dust removal bag bin and then discharged into the atmosphere. The small-particle dust in the smoke and dust is isolated and back-blown in the bag bin and falls to the bottom of the bag bin, and is transported and collected to the ash storage tank on the third floor by a scraper conveyor. After storing a certain amount, it is stirred and discharged to a ash discharge vehicle, and then transferred and sent to the coal yard for stacking and storage.

[0003] The patent document with the publication number of "CN219441064U" discloses a dust suppression mechanism for ash discharge of a ground dust removal station of a stamping coke oven, including an ash storage tank, and a humidifying mechanism for preventing dust from escaping is arranged on the lower surface of the ash storage tank.

[0004] Although the above patent document solves the problems of a large amount of dust escaping and polluting the environment during the process of discharging ash from the ash storage tank to the ash discharge vehicle, there are still the following disadvantages: After the spiral blades on the rotating shaft are used for a long time, a large amount of dust is easily left on their surfaces, and the spiral blades cannot be taken out for cleaning, which is not conducive to the subsequent normal use of the spiral blades. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of clear narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0026] Refer to Figures 1 - 7, A dust suppression device for ash discharge of a floor dust removal station of a tamping coke oven, including a dust storage tank 1, a conveying box 2, a ash discharge pipeline 5, and a humidifying mechanism (the humidifying mechanism has been disclosed in the patent document with the publication number CN219441064U, and its working principle will not be described in detail). Ear plates 3 are fixedly connected to both the conveying box 2 and the dust storage tank 1. Installation holes are provided on the ear plates 3. A rotating cylinder 21 is rotatably connected to one inner wall of the conveying box 2. An opening is provided on the other inner wall of the conveying box 2. An installation plate 6 is arranged in the opening. A limiting cylinder 10 is rotatably connected to one side surface of the installation plate 6. A rotating shaft 8 is arranged between the rotating cylinder 21 and the limiting cylinder 10. A spiral blade is fixedly connected to the rotating shaft 8. A frustum-shaped groove 19 for connecting the rotating shaft 8 is provided in the rotating cylinder 21. An annular airbag 18 is fixedly connected to the inner wall of the limiting cylinder 10. Two sliding grooves are provided on the installation plate 6. A concave rod 7 is jointly connected to each sliding groove through a first spring 14. A fixed airbag 20 is fixedly installed on one inner wall of each sliding groove. A limiting rod 12 is fixedly connected to one side surface of the concave rod 7. A limiting component is arranged on the conveying box 2.

[0027] A sealing cavity 13 communicating with the two fixed airbags 20 is provided on one side surface of the installation plate 6. A plurality of through holes are provided on the sealing cavity 13. An annular cavity communicating with the plurality of through holes and the annular airbag 18 is provided in the limiting cylinder 10. Only one side surface of the annular airbag 18 is fixedly connected to the inner wall of the limiting cylinder 10, and the sealing performance is good when the limiting cylinder 10 is connected to the installation plate 6. During the movement of the concave rod 7, the two fixed airbags 20 will be squeezed. The gas inside the two fixed airbags 20 will enter the inside of the annular airbag 18 through the through holes of the sealing cavity 13 and the annular cavity. The annular airbag 18 will expand, and its surface will be in close contact with the surface of the rotating shaft 8 after expansion.

[0028] The limiting component includes a return-shaped plate 4 fixedly installed on one side surface of the installation plate 6. A sliding rod 15 is slidably installed on the return-shaped plate 4. A clamping groove is provided on the surface of the limiting rod 12. The lower end of the sliding rod 15 is set as an arc surface. The lower end of the sliding rod 15 is clamped with the clamping groove. An inclined surface 17 is provided on the limiting rod 12. A second spring 16 is sleeved on the sliding rod 15. One end of the second spring 16 is fixedly connected to the sliding rod 15, and the other end of the second spring 16 is fixedly connected to the return-shaped plate 4. After one end of the limiting rod 12 moves together with the concave rod 7, the inclined surface 17 of the limiting rod 12 will contact and be in close contact with the arc surface of the sliding rod 15. The sliding rod 15 and the return-shaped plate 4 will slide relatively, and the second spring 16 will deform. The arc surface of the sliding rod 15 will subsequently fit with the horizontal surface of the limiting rod 12. When the sliding rod 15 and the clamping groove are facing each other, under the elastic force of the second spring 16, the lower end of the sliding rod 15 will be clamped with the clamping groove, thereby preventing the installation plate 6 from moving randomly.

[0029] One side surface of the mounting plate 6 is fixedly connected with two positioning rods 9. Two positioning holes are formed on the conveying box 2. When the mounting plate 6 is installed on one side of the conveying box 2, one end of each positioning rod 9 will penetrate through the corresponding positioning hole. The positioning rods 9 play a positioning role in the installation of the mounting plate 6. A sealing plate 11 is fixedly connected inside the conveying box 2. A circular hole for connecting the rotating shaft 8 is formed on the sealing plate 11. The sealing performance is good when the sealing plate 11 is connected with the rotating shaft 8, which can effectively prevent dust from entering the inside of the frustum-shaped groove 19.

[0030] In the present utility model, during installation, one end of the rotating shaft 8 penetrates through the circular hole on the sealing plate 11 until one end of the rotating shaft 8 is in close contact with the inner wall of the frustum-shaped groove 19 made of rubber material. Then, the mounting plate 6 is installed on one side of the conveying box 2. One end of each positioning rod 9 will penetrate through the corresponding positioning hole. After the limiting cylinder 10 moves, it will be sleeved on the outside of the rotating shaft 8 until the surface of the mounting plate 6 is in contact with the surface of the conveying box 2. Then, the concave rod 7 is pushed. During the movement of the concave rod 7 inside the sliding groove, since both ends of each first spring 14 are fixedly connected with the concave rod 7 and the inner wall of the corresponding sliding groove respectively, the first spring 14 deforms. Only one side surface of each fixed airbag 20 is fixedly connected with the inner wall of the sliding groove. When the concave rod 7 moves, it will squeeze the two fixed airbags 20. The gas inside the two fixed airbags 20 will enter the inside of the annular airbag 18 through the through holes of the sealing cavity 13 and the annular cavity. The annular airbag 18 will expand, and its surface will be in close contact with the surface of the rotating shaft 8 after expansion. After one end of the limiting rod 12 moves, the lower end of the sliding rod 15 will be engaged with the card slot, thereby preventing the mounting plate 6 from moving randomly. Subsequently, the servo motor drives the rotating cylinder 21 to rotate, and the rotating shaft 8, the spiral blade and the limiting cylinder 10 will all rotate together. Similarly, after the spiral blade on the rotating shaft 8 has a large amount of dust remaining on its surface after long-term use, the rotating shaft 8 and the spiral blade can be taken out for cleaning, which is beneficial to the subsequent normal use of the spiral blade.

[0031] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.

[0032] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should all be covered within the protection scope of the present utility model.
