[0002] An electric furnace is a heating furnace that converts the electrical energy in the furnace into heat to heat the workpiece. Electric furnaces can be divided into resistance furnaces, induction furnaces, arc furnaces, plasma furnaces, electron beam furnaces, etc. Compared with fuel furnaces, electric furnaces have the following advantages: the atmosphere in the furnace is easy to control, the material is heated quickly, the heating temperature is high, the temperature is easy to control, the production process is easier to mechanize and automate, the labor and hygiene conditions are good, the thermal efficiency is high, the product quality is good, and it is more environmentally friendly, which is conducive to alleviating the increasingly serious environmental problems.

[0003] For example, the patent document with the announcement number CN 215610167 U discloses a dust removal device for a medium frequency induction furnace, comprising a box body, a dust suction head is rotatably connected to the top of the box body, an exhaust fan is arranged inside the box body just below the dust suction head, a socket is arranged on the front side of the box body, a filter box is arranged inside the socket, the filter box has openings on both sides, a filter element is arranged inside the filter box, and dense exhaust holes are arranged on both sides of the box body aligned with the positions of the openings on both sides of the filter box. The utility model solves the problem that the opening of the heating chamber of the existing medium frequency induction furnace will cause a large amount of dust-containing air to float out of the heating chamber of the medium frequency induction furnace when heating the workpiece, thereby polluting the working environment of the entire workshop. By improving and optimizing the structure of the dust removal device, the dust removal device can be used in conjunction with the medium frequency induction furnace, so that the smoke generated by the opening of the heating chamber of the medium frequency induction furnace can be sucked away by the dust removal device.

[0004] However, during actual use, this structure can often only perform dust removal operations after the electric furnace stops running. However, when the electric furnace is actually running, there is still a problem of a large amount of dust flying, which affects the surrounding environment of the electric furnace. At the same time, the equipment cannot perform a safer and more reliable dust collection operation for the electric furnace and cannot meet daily use needs. Therefore, it is urgent to design a dust removal device for an electric furnace to solve the above problems. Utility Model Content

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

[0014] The dust removal device for an electric furnace is provided with a heat-insulating outer cover, an electric furnace body, a top sleeve ring, a bottom sleeve ring, a connecting pipe, a ventilation valve, a first connecting grille and a second connecting grille. In actual use, a staff member first starts the electric furnace body inside the heat-insulating outer cover to perform normal electric furnace heating operation, and then starts the fan seat at the bottom of the collecting seat to perform suction operation from the bottom of the collecting seat. During the suction process, the top sleeve ring and the bottom sleeve ring can be connected with the collecting seat through the connecting pipe and the ventilation valve, so as to form a stable suction and dust removal structure inside the top sleeve ring and the bottom sleeve ring.
