Problems solved by technology

[0003] 1. The collection efficiency is low, and the dust is easy to accumulate and cannot be pumped away
[0004] 2. It is difficult to determine the position of the dust extraction point. Due to the movement and interference of the equipment, the dynamic change of the diameter of the steel coil, it is difficult to determine the best position for the dust extraction
[0005] 3. The system design is huge, the energy consumption is high, the degree of automation is low, the failure rate is high, and the production efficiency is low

Abstract

The invention relates to a magnesia dedusting system of an oriented silicon steel hot drawing annealing set, comprising a pneumatic valve, a dust remover, a fan, a dust-exhausting cover, an air curtain and ash transportation equipment, wherein the dust-exhausting cover and the air curtain are installed on an uncoiler and inlet scissors and are connected to the dust remover and the fan by the pneumatic valve and an air conduit; the ash transportation equipment is positioned on the lower part of the dust remover to remove magnesia dust cleaned by the dust remover. Because of adopting novel structure, the invention can overcome the defect of the prior art and especially has the advantages of high dust capturing efficiency, low energy consumption and failure rate and the like.

Description

technical field [0001] The invention relates to the dust removal field of a thermal drawing annealing unit for producing oriented silicon steel (abbreviated as CT unit or AT unit, which is also the final finished product unit of oriented silicon steel), and specifically relates to a magnesium oxide dust removal system for a hot drawing annealing unit for oriented silicon steel. Background technique [0002] The CT (thermal stretch annealing) unit is the last process in the production process of oriented silicon steel. The dust removal system at the entrance section has always been a difficult problem for design units and production units, mainly as follows: [0003] 1. The collection efficiency is low, and the dust is easy to accumulate and cannot be pumped away. [0004] 2. It is difficult to determine the position of the dust extraction point. Due to the movement and interference of the equipment, and the dynamic change of the steel coil diameter, it is difficult to deter...
