Submerged arc furnace dust remover with good dust removal effect

Abstract

The invention discloses a submerged arc furnace dust remover with a good dust removal effect, which comprises a pretreatment assembly, a dust remover main body, a first motor, a supporting plate, a first supporting rod, a feeding cylinder, a connecting pipe, a mounting ring, a connecting bag, a second supporting rod, a baffle cover, a maintenance plate, a pull rod, an exhaust pipe, a limiting ring, a screw, a limiting nut block, a limiting block and a connecting block. According to the device, by means of an installed pretreatment assembly and an installed maintenance plate, residual dust in the air can be cleaned away, and the circumstance that a large amount of dust is left in the dust remover to reduce the dust removal efficiency is avoided, so that the dust removal effect is improved;and meanwhile, the installed feeding cylinder is fixedly connected with a slag discharging pipe installed at the bottom end of the dust remover main body, the feeding cylinder is fixedly connected with a dust discharging pipe, and a spiral shaft is driven to rotate by utilizing the work of the first motor, so that the dust is cleaned, the labor intensity is reduced, the traditional cleaning mode is changed, and meanwhile, the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dust collectors, in particular to a submerged arc furnace dust collector with good dust removal effect. Background technique [0002] Submerged arc furnace is also called arc electric furnace or electric resistance electric furnace. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. The load of the submerged arc furnace transformer is continuous and stable, the impedance voltage is low, the number of voltage regulation stages is large, and the level difference is small and the overload capacity is strong. It can be divided into two types: on-load and off-excitation voltage regulation. In the pr...

Problems solved by technology

It can be divided into two types: on-load and off-excitation voltage regulation. In the process of using the submerged arc furnace, dust collectors are usually used to clean the dust in the air. However, during the use of traditional submerged arc furnace dust collectors, Usually, the dust in the filtered air remains inside the dust collector, which reduces the dust removal effect, and is not conducive to cleaning the residual dust inside the submerged arc furnace dust collector, which increases the labor intensity. At the same time, the submerged arc furnace dust collector There are usually several ash discharge pipes corresponding to each other at the bottom of the ash discharge pipe. In the process of ash discharge, it is usually necessary to discharge the dust inside the several ash discharge pipes one by one. This cleaning method reduces the work efficiency.
