Description
Technical Field
[0001] The utility model relates to the technical field of submerged arc furnace dust removal, in particular to a dust removal device for a ferrosilicon submerged arc furnace. Background Art
[0002] Submerged arc furnace dust removal is mainly to control and reduce the dust and gas generated during the operation of the submerged arc furnace, and to protect the environment and the health of workers;
[0003] Existing submerged arc furnaces generally use bag dust removal equipment for dust removal. After the bag dust collector finishes dust removal, it generally blows air into the filter bags through a blowpipe to clean the dust on them. However, since the inside of the bag dust collector is through, the blown-off dust will directly fall into the ash hopper, and then blowing air downward through the blowpipe will blow up the originally blown-off dust again, making the dust movement inside the entire dust removal equipment unstable, resulting in adhesion to the bottom outside of the filter bag, making the cleaning not clean enough. And the ash hopper is generally inclined, so when releasing dust, some fine dust will remain on the inclined surface, which is not convenient for cleaning. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that the existing bag dust collector is prone to repeatedly blowing up the dust inside, resulting in unstable dust inside the equipment, not being convenient for cleaning the inside of the equipment, and the ash hopper not being convenient for the dust to fall and be discharged.
[0005] To solve the above problems, the technical solution adopted by the utility model is a dust removal device for a ferrosilicon submerged arc furnace, which includes a dust removal box. A funnel frame is fixed at the bottom of the dust removal box. An inclined baffle is fixed near the lower part inside the dust removal box. There is an opening between one end of the inclined baffle and one side inside the dust removal box. A flap structure is rotatably arranged at the opening inside the dust removal box. Two vibration structures are arranged below the inclined baffle inside the dust removal box. A plurality of air injection pipes are fixed at the top inside the dust removal box. One end of the air injection pipe passes through the dust removal box and is located inside the funnel frame of the funnel frame.
[0006] As a further scheme of the utility model: The flap structure includes a flap for blocking the opening. A hinge seat is fixed on the lower side of the flap. A hinge shaft is fixed below the inclined baffle inside the dust removal box. A telescopic rod is rotatably arranged on the side of the hinge shaft for driving the flap to swing. One end of the telescopic rod is hinged to the hinge seat.
[0007] As a further scheme of the utility model: The vibration structure includes a rotating shaft rotating inside the dust removal box. A plurality of compression springs are evenly fixed on the side of the rotating shaft. One end of the compression spring is fixed with a knocking head for knocking the inclined baffle. A motor is fixed on one side of the dust removal box. The output end of the motor is fixed to one end of the rotating shaft.
[0008] As a further solution of the utility model: the normal length of the compression spring is less than the shortest distance between the rotating shaft and the inclined baffle, which is convenient for knocking the inclined baffle.
[0009] As a further solution of the utility model: the telescopic rod and the motor are respectively electrically connected to an external power source.
[0010] As a further solution of the utility model: a filter bag is arranged inside the dust removal box, one end of the air injection pipe is communicated with an air pump, an air inlet is arranged on one side of the dust removal box and is communicated with the exhaust dust pipeline of the external submerged arc furnace, an air outlet is communicated at the top of the dust removal box for discharging clean gas, and a dust outlet is arranged at the bottom end of the dust removal box for discharging dust.
[0011] The advantages of the utility model compared with the prior art are as follows: this patent adds an inclined baffle structure, separating the filter bag structure from the funnel frame structure, which can effectively prevent the dust inside the funnel frame from being blown up again when cleaning the filter bag through the air injection pipe, resulting in inconvenient cleaning inside the equipment; an oscillation structure is added, which can periodically knock the inclined baffle to facilitate the falling of dust, and an air injection pipe is arranged inside the funnel frame to ensure that all the dust can be blown out of the funnel frame during dust discharge.
