Telescopic dust suction system and implementation method thereof

Abstract

The invention discloses a telescopic dust suction system and an implementation method thereof. The telescopic dust suction system comprises a cage type telescopic frame group, a dust suction cover, ahigh-temperature-resistant telescopic pipe and a dust suction pipeline, wherein the high-temperature-resistant telescopic pipe is connected with dust suction ends of the dust suction cover and the dust suction pipeline; a dust removal system is connected to a conveying end of the dust suction pipeline; the high-temperature-resistant telescopic pipe is sleeved in a cavity of the cage type telescopic frame group; and the dust suction cover is connected with the cage type telescopic frame group. The telescopic dust suction system has the following advantages that an air cylinder is adopted to replace an oil cylinder, so that the flammability of oil is avoided, the telescopic dust suction system can work under the inflammable environment, and the multi-cylinder cost is saved; with the double-acting air cylinder, power is provided for telescoping, so that the lifting movement of a suspended load and a cage type frame inner cavity load is realized; and through a telescoping function, a reasonable distance is kept between the dust suction cover and a furnace cover, so that a best dust suction effect is achieved.

Description

technical field [0001] The invention relates to a dust suction system, in particular to a telescopic dust suction system. Background technique [0002] Foundry industry and amorphous alloy industry use electric furnace to smelt molten steel. Electric furnace smelting (hereinafter referred to as smelting furnace) will produce smoke and dust pollution during the working process. Some smelting furnaces have a dust suction system on the furnace cover, and some smelting furnaces have There is no vacuum system. [0003] For smelting furnaces with a dust suction system on the furnace cover, during the smelting process, feeding process, temperature measurement process, and pouring of molten steel, there will be smoke and dust that is not sucked away, but will be emitted into the surrounding environment. [0004] In the smelting furnace without dust suction system on the furnace cover, the smoke and dust in the whole process will be distributed in the surrounding environment. [00...

AI Technical Summary

Problems solved by technology

Even if it is installed, because the height of the smelting furnace changes during the working process, the height of the vacuum hood is too close to the furnace mouth, and the dust collection effect is good, but it is easy to be damaged by high temperature and hinder the normal operation of the smelting furnace; Too high and the vacuum effect is not good; basically nothing

[0006] This does not comply with the "Environmental Protection Law", especially if the dust content is not greater than 15mg / m 3 standard
