Drum type dust removal device for easy disassembly of induced draft fan

Abstract

The invention discloses a drum-type dedusting device which can be easily disassembled by an induced draft fan. The drum has a cylindrical structure, and the cylinder is incompletely separated by several partitions; the drum is connected with a motor and can rotate with the motor at high speed; The upper and lower ends of the drum have openings, the upper air collection box is connected to the air inlet, the lower air collection box is connected to the induced draft fan, and the air outlet of the induced draft fan is connected to the bag filter; the lower air collection box is equipped with a dust removal door for easy dust removal ; The impeller of the induced draft fan can use the centrifugal force to clean up the dust in time. The invention not only has simple structure and good dust removal effect, but more importantly, it greatly improves the disassembly and assembly technology of the induced draft fan, so that it can simply eliminate the pressure on the end surface of the screw shaft shoulder by similar nut parts during disassembly, and effectively solve the problem of the induced draft fan. The problem that the threaded assembly is continuously and automatically locked under load and difficult to disassemble is especially suitable for the convenient disassembly of large fans after the thread is locked, and the effect is particularly remarkable.

Description

technical field [0001] The invention relates to a drum-type dust removal device, in particular to a drum-type dust removal device with no dust accumulation in the fan and easy disassembly. Background technique [0002] Exhaust dust removal is essential in many industrial productions. At present, cyclone dust removal, bag filter dust removal and pulse dust removal are widely used. Among them, cyclone dust removal is widely used because of its simple structure, durability, and low failure rate. The efficiency is not very high, and the separation factor is small, so it is impossible to achieve a very thorough dust removal; the bag type dust removal is a filter type, and the effect is good, but the air resistance is large during use, the wind pressure is high, and the energy consumption is large; the pulse type dust removal consumes a lot of energy. It is relatively low and has good dust removal effect, but the structure is more complicated and the manufacturing cost is high. T...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
