The practicability is high, use is quite convenient, dust removal can be carried out on the plug of an intermediate frequency furnace conveniently, rapidly and efficiently, the manpower and material cost produced in the dust removal work of the plug of the intermediate frequency furnace can be effectively saved, and production safety guarantee and production efficiency of enterprises are greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of intermediate frequency furnace auxiliary equipment, in particular to a dustproof device for intermediate frequency furnace plugs. 【Background technique】 [0002] As we all know, intermediate frequency furnaces are widely used in the smelting of non-ferrous metals and ferrous metals. Compared with other casting equipment, intermediate frequency induction furnaces have high thermal efficiency, short melting time, less burning loss of alloy elements, wide range of melting materials, and little environmental pollution. , can accurately control the temperature and composition of molten metal, etc., so the use of intermediate frequency furnaces is very common in the smelting industry. Before the intermediate frequency furnace is put into production, there are usually some plugs reserved for connection on the intermediate frequency furnace. When the furnace is in use, it will be connected to control equipment,...

[0002] As we all know, intermediate frequency furnaces are widely used in the smelting of non-ferrous metals and ferrous metals. Compared with other casting equipment, intermediate frequency induction furnaces have high thermal efficiency, short melting time, less burning loss of alloy elements, wide range of melting materials, and little environmental pollution. , can accurately control the temperature and composition of molten metal, etc., so the use of intermediate frequency furnaces is very common in the smelting industry. Before the intermediate frequency furnace is put into production, there are usually some plugs reserved for connection on the intermediate frequency furnace. When the furnace is in use, it will be connected to control equipment, hydraulic equipment, power supply equipment, etc., but these plugs, especially those connected to hydraulic pipes, have very high requirements for dust protection. Dust cannot enter the wall of the plug pipe, otherwise it will After the plug connection is completed, dust will enter the equipment along with the connecting pipe, which will cause certain safety hazards during the operation of the equipment, and seriously cause damage to the equipment. At present, there is no dust-proof device for the connection plug of the intermediate frequency furnace, and it is usually used to cover, etc. Dustproof method, this kind of dustproof method will not only cause the staff to repeat operations and cause waste of manpower and material resources, but also the dustproof effect is very poor, which is not conducive to the production safety in the use of intermediate frequency furnaces, and greatly affects the production and development of enterprises.
