[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Referring to Figures 1-5 A steelmaking waste gas treatment device, including waste gas treatment box 1 and water tank 9, one side of waste gas treatment box 1 is equipped with inlet pipe, the other side of waste gas treatment box 1 is equipped with outlet pipe, the top outer wall of waste gas treatment box 1 is welded with guide frame 2, sliding sleeve connection is set on guide frame 2 sliding frame 4, two threaded rods 3 are rotatably inserted between the top and bottom of guide frame 2, sliding frame 4 is threadedly connected with threaded rod 3, rotating rod 5 is rotatably inserted at the bottom between the inner walls of both sides of sliding frame 4, rotating roller 6 is fixedly connected to the outer wall of rotating rod 5, rotating roller 6 is located at the bottom of waste gas treatment box 1, two collection boxes 7 are embedded in the top and bottom of rotating roller 6, guide cover 17 is welded between the inner walls of multiple sides of waste gas treatment box 1, the bottom end of guide cover 17 is in contact with collection box 7, so as to guide the falling of particulate matter, so that the particulate matter falls into collection box 7 and is collected;

[0025] One end of rotating rod 5 is keyed with worm wheel 15, one side of the outer wall of sliding frame 4 is transversely rotatably connected with worm 14, worm 14 is engaged with worm wheel 15, worm 14 is twisted, rotating rod 5 is driven to rotate under the engagement of worm 14 and worm wheel 15, so as to drive rotating roller 6 to rotate, and then drive collection box 7 to overturn, so as to overturn the opening of collection box 7 containing particulate matter downward, so as to pour down the particulate matter, the top end of threaded rod 3 is keyed with gear 16, two gears 16 are engaged, threaded rod 3 is twisted, and then sliding frame 4 moves downward along guide frame 2 under the engagement of the two gears 16, so as to drive rotating roller 6 to move downward, and then make rotating roller 6 separate from the bottom of waste gas treatment box 1,

[0026] The sealing frame 8 is bonded between the multiple side inner walls of the exhaust gas treatment box 1 and is in contact with the rotating roller 6, thereby sealing the rotating roller 6 and the exhaust gas treatment box 1, and preventing the leakage of exhaust gas. The top inner wall of the exhaust gas treatment box 1 is fixed with a water distribution tray 10 by bolts. The bottom of the water distribution tray 10 is inserted with multiple spray heads 11. The top outer wall of the water tank 9 is fixed with a pump body 12 by bolts. The water inlet end of the pump body 12 is inserted with the water tank 9. The water outlet end of the pump body 12 is inserted with the water distribution tray 10. Under the action of the pump body 12, the water in the water tank 9 is input into the water distribution tray 10, and then sprayed from the spray heads 11 to wash the exhaust gas. The top of the water tank 9 is inserted with a connecting pipe 13. The other end of the connecting pipe 13 is inserted with the exhaust gas treatment box 1. The end of the connecting pipe 13 entering the exhaust gas treatment box 1 is clamped with a filter cover 18. The sewage is filtered by the filter cover 18 and then collected back into the water tank 9 from the connecting pipe 13. The side inner wall of the exhaust gas treatment box 1 is welded with an inclined baffle 19, thereby avoiding the particulate matter falling into the connecting pipe 13. The inclined baffle 19 is located above the filter cover 18.

[0027] The working principle of the embodiment is as follows: in use, first, the exhaust gas is input into the exhaust gas treatment box 1 from the air inlet pipe. Then, the pump body 12 is started. Under the action of the pump body 12, the water in the water tank 9 is input into the water distribution tray 10, and then sprayed from the spray heads 11 to wash the exhaust gas, thereby removing the particulate matter in the exhaust gas. Then, the particulate matter falls into the collection box 7 for collection. Then, the sewage is filtered by the filter cover 18 and then collected back into the water tank 9 from the connecting pipe 13. The treated exhaust gas is discharged into the conveying pipeline from the air outlet pipe for subsequent treatment.

[0028] When it is necessary to clean the particulate matter in the collection box 7, the delivery of the exhaust gas is paused, the threaded rod 3 is twisted, and then the sliding frame 4 moves downward along the guide frame 2 under the action of the meshing of the two gears 16, thereby driving the rotating roller 6 to move downward, and further separating the rotating roller 6 from the bottom of the exhaust gas treatment box 1. Then, the worm 14 is twisted, and the rotating rod 5 is driven to rotate under the action of the meshing of the worm 14 and the worm wheel 15, thereby driving the rotating roller 6 to rotate, and further driving the collection box 7 to overturn. Thus, the opening of the collection box 7 containing the particulate matter is overturned to face downward, so as to pour down the particulate matter, and the opening of the empty collection box 7 is overturned to face upward. Then, the threaded rod 3 is twisted in the reverse direction, so that the rotating roller 6 moves upward, thereby blocking the rotating roller 6 at the bottom of the exhaust gas treatment box 1, and making the rotating roller 6 in contact with the sealing frame 8, thereby sealing the rotating roller 6 and the exhaust gas treatment box 1, and preventing the leakage of exhaust gas.

[0029] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
