An integrated device for dust removal and molding of micro-silica powder

Abstract

The invention relates to an integrated device for dust removal and molding of micro silicon powder. The adopted technical scheme is: including dust removal device, air inlet, air outlet, cleaning device, dust collection box, control device, stirring device, dehydration forming device, dry ice machine, column, fixing plate, fixing hole, bolt. The use of a wheel-type high-temperature resistant metal dust removal net can save the cooling treatment of exhaust gas; second, it can make the dust removal net have the advantages of anti-damage and corrosion, and save a lot of replacement costs; third, because the metal net rotates at the air inlet and outlet , Secondary filtration can be performed when the wind is discharged. Use dry ice to clean the metal mesh regularly to prevent the blockage of the mesh from affecting the dust removal effect. After dedusting, micro-silica powder is stirred with water to improve its cohesive force. After extrusion and dehydration, it is molded into strips or blocks by vacuum extruder, which is convenient for handling and transportation.

Description

technical field [0001] The invention belongs to the field of dust removal and relates to an integrated device for dust removal and molding of micro silicon powder. Background technique [0002] Microsilica fume is also called silica fume or condensed silica fume. It is ferroalloy. When smelting ferrosilicon and industrial silicon, a large amount of highly volatile SiO2 and Si gases are produced in the submerged electric furnace. After the gas is discharged, it oxidizes, condenses and precipitates with air rapidly. made. It is a by-product of large-scale industrial smelting, and the entire process needs to be recycled with dust removal and environmental protection equipment. The bag filter is usually used to collect micro silica fume. The dust bag is called the heart of the bag filter. It is generally called a dust bag or a filter bag. The dust bag is a key part in the operation of the bag filter. The filter bags are hung vertically in the dust collector. Due to the high t...

AI Technical Summary

Problems solved by technology

Due to the high temperature of the exhaust gas, it needs to be cooled before dust can be removed, and the dust removal bag is easy to wear and corrode, which affects the dust removal effect. Long-term use will cause the mesh to be blocked and the resistance will be too high. It needs to be removed and cleaned or replaced frequently, which is time-consuming and laborious.

After dedusting, the microsilica dust still needs to be collected into the bag, and there is still secondary pollution in the collection process, and the powdery dust is inconvenient in the transportation process, prone to dust phenomenon
