[0001] This utility model relates to the technical field of dust removal equipment used in steelmaking, specifically a dust removal device used in steelmaking. Background Technology
[0002] Existing steelmaking boilers often generate a large amount of dusty air during steelmaking. If the air is discharged without treatment, it will cause serious air pollution and have adverse effects on the environment and operators.
[0003] Chinese patent CN213375535U discloses a dust removal device for steel plants, belonging to the field of dust removal technology. It includes a housing and a sound insulation layer. The sound insulation layer is tightly fitted to the inner wall of the housing. A motor is fixedly installed on one side of the housing. A main shaft is fixedly connected to the left end of the motor. A rotating rod is fixedly connected to one end of the main shaft. A brush is fixedly connected to the right side of the rotating rod. A dust collection box is located below the brush. A filter screen is fixedly installed on the upper side of one side of the dust collection box. An activated carbon filter layer is fixedly connected to the middle of the housing. In this invention, the brush inside the dust removal device is driven to rotate by the main shaft. The brush then sweeps the dust off the filter screen, allowing it to fall into the dust collection box. This eliminates the need for manual cleaning of the filter screen, solving the problem of dust easily clogging the filter screen of existing steel plant dust removal equipment after a period of use.
[0004] However, the above patent has the following shortcomings: the brush in the above patent will wear down and become shorter during long-term contact with the filter screen, thus failing to effectively clean the filter screen. Utility Model Content

[0010] By adopting the above technical solution, the fan blades are driven to rotate by a bidirectional motor, which in turn draws air from the slide bar into the exhaust pipe.
[0011] As a further embodiment of this utility model: a second filter plate is installed horizontally at an angle inside the spray box.
[0012] By adopting the above technical solution, the sprayed water can be filtered through the second filter plate.
[0013] As a further embodiment of this utility model: the circulating dust suppression component includes a water pump, a metal pipe and a spray head. A metal pipe is installed at the top of the base, and multiple spray heads are installed at the bottom of the metal pipe. A water pump is installed on the outside of the spray box, and the suction end of the water pump is connected to the bottom of the spray box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 This utility model provides a technical solution: a dust removal device for steelmaking, including a base 1, a spray box 2 vertically mounted on the top of the base 1, an exhaust pipe 3 horizontally mounted on the side wall of the spray box 2, a first filter plate 6 vertically mounted inside the exhaust pipe 3, a cleaning component disposed on the outside of the first filter plate 6, a suction component disposed inside the exhaust pipe 3, a sliding rod 12 horizontally mounted on the side wall of the spray box 2, and a circulating dust suppression component disposed on the outside of the spray box 2.
[0025] The cleaning assembly includes a mounting plate 11, a slide rod 12, a cleaning brush 13, and a spring 14. The slide rod 12 slides horizontally through the side wall of the mounting plate 11, and the cleaning brush 13 is vertically installed at the through end of the slide rod 12. The spring 14 is sleeved on the outside of the slide rod 12, and the spring 14 is located between the cleaning brush 13 and the mounting plate 11.
[0026] Specifically, when the cleaning brush 13 cleans the first filter plate 6, the sliding rod 12, which is horizontally slidably mounted on the mounting plate 11, moves horizontally under the push of the spring 14. The spring 14 constantly pushes the cleaning brush 13 closer to the first filter plate 6, thus ensuring that the cleaning brush 13 and the first filter plate 6 are always in effective contact.
[0027] Furthermore, the suction assembly includes a bidirectional motor 4 and a gearbox 5. The bidirectional motor 4 is installed inside the exhaust pipe 3, and a fan blade is installed at one end of the bidirectional motor 4. The other end of the bidirectional motor 4 is connected to the gearbox 5. The output end of the gearbox 5 rotates laterally through the first filter plate 6, and a mounting plate 11 is installed vertically at the through end of the gearbox 5.
[0028] Specifically, by starting the bidirectional motor 4, the fan blades are driven to rotate. The fan blades can bring air from the slide bar 12 into the exhaust pipe 3 for dust removal and then discharge it. At the same time, the bidirectional motor 4 actuates the first filter plate 6 to work, and the speed is reduced by the first filter plate 6.
[0029] Furthermore, a second filter plate 8 is installed horizontally at an angle inside the spray box 2;
[0030] Specifically, the dust in the incoming air in the spray box 2 is sprayed through the second filter plate 8, and then the sprayed dust is filtered through the second filter plate 8.
[0031] Furthermore, the circulating dust suppression assembly includes a water pump 7, a metal pipe 9, and a spray head 10. The metal pipe 9 is installed at the top inside the base 1, and multiple spray heads 10 are installed at the bottom of the metal pipe 9. The water pump 7 is installed on the outside of the spray box 2, and the suction end of the water pump 7 is connected to the bottom of the spray box 2. The output end of the water pump 7 is connected to the metal pipe 9 through a pipe.
[0032] Specifically, by starting the water pump 7, the water at the bottom of the spray box 2 is brought into the metal pipe 9, and then the spray head 10 installed at the bottom of the metal pipe 9 sprays the water into the spray box 2, which can be recycled multiple times.
[0033] Furthermore, the bottom of the spray box 2 is set at an angle;
[0034] Working principle: When using this dust removal equipment in steelmaking, the bidirectional motor 4 is started to drive the fan blades to rotate. The fan blades can bring air from the slide rod 12 into the exhaust pipe 3 for dust removal and then discharge it. At the same time, the bidirectional motor 4 actuates the first filter plate 6 to work. The slide rod 12, which is horizontally slidable on the mounting plate 11, moves horizontally under the push of the spring 14. The spring 14 constantly pushes the cleaning brush 13 closer to the first filter plate 6, so that the cleaning brush 13 and the first filter plate 6 can always be in effective contact. The water pump 7 is started to bring the water from the bottom of the spray box 2 into the metal pipe 9. Then, the water sprayed into the spray box 2 through the water spray head 10 installed at the bottom of the metal pipe 9. It can be recycled multiple times.
