Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for intermediate frequency furnaces, and specifically relates to a dust removal device for an intermediate frequency melting furnace. Background Technique

[0002] The dust treatment of intermediate frequency melting furnaces has always been solved by directly discharging or adding a smoke exhaust hood at the furnace mouth. The direct discharge has a large amount of dust, and the dust removal effect of adding a smoke exhaust hood is not good, and the problem of dust backflow is likely to occur.

[0003] Therefore, some people usually set up a water tank on the pipeline to cool and filter the discharged flue gas, and set a filter screen and a dust-proof plate on the top of the water tank to enhance the dust-proof effect. For example, the Chinese utility model patent with the publication number CN218097262U specifically discloses a dust removal device for an intermediate frequency furnace.

[0004] However, during the actual use of the above-mentioned dust removal device for an intermediate frequency furnace, people will find that the filter screen and the dust-proof plate set on the device are fixed on the top of the water tank. After long-term use, a large amount of impurities adhere to the filter screen and the dust-proof plate. At this time, maintenance is required. However, since the filter screen and the dust-proof plate are fixed on the water tank, it is difficult to disassemble and assemble them, which is very inconvenient for later maintenance. Content of the Utility Model

An installation groove is opened above the filtering water tank, the mesh frame is arranged in the installation groove, a filter screen is arranged in the middle of the mesh frame, the threaded sleeve is sleeved on the position of the filtering water tank close to the upper part, and the threaded sleeve is threadedly connected with the filtering water tank. A pressing ring is fixed above the threaded sleeve, and the pressing ring presses on the upper part of the mesh frame; the fixed block is fixed on the side of the filtering water tank, a slot is opened above the fixed block, a connecting hole is opened on the side of the fixed block, the dust-proof plate is located above the filtering water tank, a plug rod is fixed on the dust-proof plate, the plug rod is inserted into the slot, a threaded hole is opened on the plug rod, the connecting hole is aligned with the threaded hole and fixed by a bolt.

[0007] When the dust-proof plate needs to be removed, only need to screw out the bolt from the threaded hole, and then the plug rod can be pulled out from the slot, so as to remove the dust-proof plate. When removing the filter screen, only need to unscrew the threaded sleeve from the filtering water tank, and then the mesh frame can be taken out from the installation groove.

[0008] Preferably, an air inlet and a drain outlet are arranged at the bottom of the filtering water tank, a valve is arranged on the drain outlet, and the air inlet is used to connect the dust discharge pipeline of the intermediate frequency melting furnace.

[0009] Preferably, a limiting groove is provided on the inner wall of the installation groove, and a limiting block is arranged on the outer side of the wire frame. The limiting block is inserted into the limiting groove to limit the wire frame, improving the stability of the wire frame.

[0010] Preferably, concave stripes are provided on the outer side wall of the threaded sleeve. The provided concave stripes are mainly used to improve the anti-slip effect and facilitate the rotation of the threaded sleeve.

[0011] Preferably, the dust-proof plate is conical. The design of the dust-proof plate can, to a certain extent, make the dust slide along the surface and not accumulate.

[0012] Preferably, a rubber pad is arranged on the inner wall of the installation groove. The provided rubber pad is mainly used to prevent the smoke and dust from leaking out from the side.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
