Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and particularly to an on-tank dust removal device for blast furnace bins in an ironmaking plant. Background Art

[0002] Air dust removal equipment is used to treat solid waste pollution and air pollution. It uses civilian indoor air purifiers or high-efficiency activated carbon for adsorption, for environmental protection project construction and ecological protection project construction. The blast furnace bin is a part of the blast furnace ironmaking feeding system. The blast furnace ironmaking feeding system also includes belt conveyors and charging cars. The required ore materials for production are transported to the blast furnace bin through the belt conveyors and charging cars. A mobile charging car is provided in the bin section of the belt conveyor. The materials transported by the belt conveyor are discharged into each bin through the chute pipes arranged on both sides of the charging car. Among them, during the discharging process of the charging car, due to a certain height difference between the discharging port and the bin, a large amount of dust will be generated. Therefore, a corresponding dust removal device must be set up to provide a good working environment for workers.

[0003] The existing dust removal equipment is arranged outside the bin in the form of a mobile vehicle. The bin is wrapped by a dust suction hood to absorb the dust in the bin. During this process, the filtration of dust mainly relies on the filter plate to adsorb and filter impurities in the air. After long-term use, dust is likely to accumulate on the filtration facilities and the inner wall of the pipeline, resulting in a decline in the filtration and dust removal effect and being inconvenient to clean. Summary of the Invention

[0014] Further, a top rod is fixed to one end of the dust suction pipe, and the top rod is in extrusion contact with the surface of the rotating plate.

[0015] Advantages of the present invention:

[0016] 1. For the present invention, the discharge pipe at the bottom of the dust collection box facing the dust suction station is communicated with the fan box through an electric telescopic sleeve. Under the push of a bidirectional electric push rod, the dust suction pipes and the dust collection box facing the top and bottom of the connection layer, the second telescopic sleeves are respectively sleeved on the inlet ends of the dust suction pipe and the dust collection box. Through the connection of the fixing frame, the first telescopic sleeve on the dust suction hood is sleeved on the front surface of the front end of the dust suction pipe. Sealing rings are arranged on the inner walls of the first telescopic sleeve, the second telescopic sleeve and the electric telescopic sleeve, which can ensure the sealing performance. At the same time, the connection with the dust suction hood, the connection layer and the fan box can facilitate the movement of the dust collection box and the dust suction pipe by the retracting method, and no movement interference will occur.

[0017] 2. When the two groups of dust collection boxes and dust suction pipes are switched for use in the present invention, the dust collection boxes can be driven to move to both sides respectively through the moving plate, and a combination of a group of dust collection boxes and dust suction pipes is always connected to the dust suction hood and the fan box to maintain the dust removal ability. At this time, the other group can carry out the cleaning work. The driving motor drives the first screw rod to rotate, and the two dust collection boxes slide along the sliding grooves on the base, driving the dust suction pipe to be switched. The dust collection box moved to the cleaning station is pushed by the first electric push rod on one side of the moving plate to move the side plate outwards, and the telescopic rod extends at the extending end, and the filter plate is pulled outwards, which is convenient for cleaning the surface of the filter plate.

[0018] 3. Through the connection of the side frame in the present invention, after the dust collection box moves to the cleaning station, the internal filter plate is pulled out. At this time, the scraping plate just corresponds to the top of the filter plate. As the side frame moves, the scraping plate moves along the surface of the filter plate, scraping the accumulated dust on the filter plate and falling into the collecting tray inside, maintaining the good ability of the filter plate to filter dust particles.

[0019] 4. When the rotating plate approaches the ejector rod side of the present invention, it is squeezed by the ejector rod. The top and bottom of the rotating plate rotate along the slider. At this time, the inside of the dust suction pipe is in an open state and can be used for air flow. The two ends of the dust suction pipe switched to the dust suction station correspond to the collection box. At this time, the second electric push rod drives the extrusion block to move, squeezing the surface of the loop rope passing through the dust suction pipe. Subsequently, the small motor drives the rotation of the second screw rod, and the screw block is threadedly engaged with the second screw rod to drive the extrusion block to translate. The loop rope moves inside the dust suction pipe, pulling the slider and the rotating plate to move. After the rotating plate leaves the extrusion of the ejector rod, it is reset by its own torsion spring and forms a complete disc shape with the slider to clean the inner wall of the dust suction pipe. The dust removed by cleaning falls into the collection box from both ends.

[0020] 5. Compared with the prior art, the two groups of dust collection boxes and dust suction pipes of the present invention can be switched to be connected to the dust suction hood through the translation component and used alternately, which can save waiting time. The filter plates of the dust collection boxes sent out and the inside of the dust suction pipes are synchronously cleaned by the cleaning components on both sides, and the accumulated dust is cleaned to avoid affecting the efficiency of dust treatment in the air.

The filter plate 22 is fixedly connected to the side plate 23, and the connecting plate 56 is fixedly connected to the outside of the side plate 23. When the two dust collection boxes 2 and the dust suction pipes 3 are switched for use, the dust collection box 2 can be driven by the moving plate 54 to move to both sides respectively, so that a combination of a dust collection box 2 and a dust suction pipe 3 is always connected to the dust suction hood 4 and the blower box 13 to maintain the dust removal ability, and the other group can be cleaned at this time. The driving motor 53 drives the first screw rod 52 to rotate, and the two dust collection boxes 2 slide along the sliding groove 15 on the base 1 to drive the dust suction pipes 3 to be switched. The dust collection box 2 moved to the cleaning station is pushed by the first electric push rod 55 on one side of the moving plate 54 to move the side plate 23 outwards, and the extending end of the telescopic rod 24 and the filter plate 22 are pulled outwards to facilitate the cleaning of the surface of the filter plate 22.

[0034] In this embodiment, the cleaning component 6 further includes a second screw rod 63. The bottom of the connecting frame 62 is rotatably installed with the second screw rod 63, and a screw block 65 is threadedly sleeved on the surface of the second screw rod 63.

The two ends of the base 1 are fixed with collection trays 12. A rotating plate 31 is arranged inside the dust suction pipe 3, and sliders 32 are rotatably installed at the top and bottom of the rotating plate 31 through bearings and torsion springs.

One end of the dust suction pipe 3 is fixed with a top rod 34, and the top rod 34 is in pressing contact with the surface of the rotating plate 31. In the initial state, the rotating plate 31 is close to the side of the top rod 34 and is pressed by the top rod 34. The top and bottom of the rotating plate 31 rotate along the sliders 32. At this time, the inside of the dust suction pipe 3 is in an open state and can be used for air flow. The two ends of the dust suction pipe 3 switched to the dust suction working position correspond to the collection box 61. At this time, the second electric push rod 64 drives the extrusion block 66 to move, pressing the surface of the loop rope 35 passing out of the dust suction pipe 3. Then, the second screw rod 63 is driven to rotate by a small motor. The threaded cooperation between the screw block 65 and the second screw rod 63 drives the extrusion block 66 to translate. The loop rope 35 moves inside the dust suction pipe 3, pulling the sliders 32 and the rotating plate 31 to move.

Subsequently, the position of the dust suction hood 4 is corresponding to the top of the blast furnace bunker. Through the fan box 13, the air with dust enters the interior of the dust collection box 2 from the dust suction hood 4, the dust suction pipe 3, and the connecting layer 7. After filtering the dust particles through the two filter plates 22 in the dust collection box 2, it is discharged from the exhaust pipe 14 outside the fan box 13. The discharge pipe 26 at the bottom of the dust collection box 2 facing the dust suction station is communicated with the fan box 13 through the electric telescopic sleeve 16. Driven by the bidirectional electric push rod 72, the second telescopic sleeve 71 is respectively sleeved on the inlet ends of the dust suction pipe 3 and the dust collection box 2. Through the connection of the fixing frame 73, the first telescopic sleeve 41 on the dust suction hood 4 is sleeved on the front surface of the front end of the dust suction pipe 3. Sealing rings are provided on the inner walls of the first telescopic sleeve 41, the second telescopic sleeve 71, and the electric telescopic sleeve 16, which can ensure the sealing performance. At the same time, the connection with the dust suction hood 4, the connecting layer 7, and the fan box 13 can facilitate the movement of the dust collection box 2 and the dust suction pipe 3 through the retracted method without movement interference. When the two groups of dust collection boxes 2 and dust suction pipes 3 are switched for use, the dust collection box 2 can be driven to move to both sides by the moving plate 54 respectively, always keeping a combination of a group of dust collection boxes 2 and dust suction pipes 3 connected to the dust suction hood 4 and the fan box 13 to maintain the dust removal ability, and the other group can perform cleaning work at this time. The driving motor 53 drives the first screw rod 52 to rotate, and the two dust collection boxes 2 slide along the chute 15 on the base 1 to drive the dust suction pipe 3 to switch.

In the initial state, the rotating plate 31 is close to one side of the ejector rod 34 and is squeezed by the ejector rod 34. The top and bottom of the rotating plate 31 rotate along the slider 32. At this time, the interior of the dust suction pipe 3 is in an open state and can be used for the flow of air. The two ends of the dust suction pipe 3 switched out of the dust suction station correspond to the collection box 61. At this time, the second electric push rod 64 drives the extrusion block 66 to move, squeezing the surface of the loop rope 35 passing through the dust suction pipe 3. Subsequently, the second screw rod 63 is driven to rotate by a small motor, and the screw block 65 is threadedly engaged with the second screw rod 63 to drive the extrusion block 66 to translate. The loop rope 35 moves inside the dust suction pipe 3, pulling the slider 32 and the rotating plate 31 to move. After the rotating plate 31 leaves the extrusion of the ejector rod 34, it is reset by its own torsion spring and forms a complete disc shape with the slider 32 to clean the inner wall of the dust suction pipe 3, and the cleaned dust falls into the collection box 61 from both ends. At the same time, through the connection of the side frame 67, after the dust collection box 2 moves to the cleaning station, the internal filter plate 22 is pulled out. At this time, the scraper 68 just corresponds to the top of the filter plate 22. As the side frame 67 moves, the scraper 68 moves along the surface of the filter plate 22 to scrape the dust accumulated on the filter plate 22 and fall into the collection tray 12.Maintain the good ability of the filter plate 22 to filter dust particles.
