Electric furnace with dust remover

Abstract

The invention discloses an electric furnace with a dust remover, which comprises an electric furnace body, a dust-collecting box, an exhaust fan, a ventilating duct and an inclined suction pipe; the dust-collecting box is arranged on the bottom of the electric furnace body, and is communicated with the electric furnace body; the ventilating duct is connected with the exhaust fan; the inclined suction pipe is arranged on the bottom of the dust-collecting box; the bottom of the dust-collecting box is inclined; and the inclination of the bottom of the dust-collecting box is equal to the inclination of the inclined suction pipe. The electric furnace with the dust remover disclosed by the invention has the advantages that since the inclined suction pipe is arranged on the bottom of the dust-collecting box and the inclination of the bottom of the dust-collecting box is equal to the inclination of the inclined suction pipe, the pressure loss of wind power is little, moreover, dead corners do not exist, dust in the dust-collecting box can be thoroughly sucked out, consequently, the dust can be prevented from being agglomerated to occupy the space of the dust-collecting box, maintenance is reduced, and the use cost is reduced; and meanwhile, the interior of a furnace chamber can be kept clean as well.

Description

technical field [0001] The invention relates to an improvement of an electric furnace, in particular to an electric furnace with a dust removal device which conveniently and cleanly extracts ash from the side wall of the ash box, and has less carbon deposition in the hearth, belonging to the technical field of electric furnaces. Background technique [0002] Many metal processing parts, such as hardware parts, auto parts, tools, etc., need to be heat treated by electric furnace to increase their surface hardness, so as to improve their wear resistance and contact strength to meet their respective design needs. In the prior art, the electric furnace produces a lot of soot during the heat treatment process of the processed metal parts. If the excess soot is not discharged from the electric furnace in time, the excess soot will be deposited on the inner wall or bottom of the furnace in large quantities, forming at high temperature carbon layer. As the carbon layer accumulates,...

Problems solved by technology

Then, it is necessary to manually clean the carbon layer. Generally, the carbon layer needs to be cleaned 4-5 times a year. The maintenance cost of the electric furnace is very high, and it will affect the normal production and operation of the factory.

At present, many electric furnaces are equipped with ash boxes, which are generally cylindrical in shape. In order to remove dust from the ash box, in many cases, it is necessary to install an oblique suction from the side of the ash box. The inclined suction pipe is connected with the exhaust fan. Since the bottom of the ash box is horizontal, there is always some residual dust in the ash box. After a long time, the residual dust will agglomerate, and then , it is difficult to be sucked away by the exhaust fan, so that the space of the dust box becomes smaller and smaller, so it needs to be cleaned regularly, and cleaning the dust box is dirty and troublesome
