Description

Cloth bag dust remover component for pulse valve leakage inspection

Technical Field

The utility model relates to pulse valve leakage inspection, in particular to a cloth bag dust remover component for pulse valve leakage inspection.

Background

The pulse valve plays a key role in the operation of the bag dust removal system, plays a role in the dust removal of the bag, is arranged on the compressed air box body and is connected with the injection pipeline and is used for controlling the connection of the injection pipeline and the compressed air box body, so that the injection pipeline is controlled to inject air into the dust remover bin. If the pulse valve leaks and can cause the air supply pressure in the compressed air box to be low in time treatment, the whole dust removal jetting effect is poor, the cloth bag permeability is low, the negative pressure of the inlet of the dust remover is reduced, and the dust pumping point is raised.

If the dust remover needs to check the leakage of a specific pulse valve, the prior technical scheme is relatively complex and takes a long time, at least 3 persons are needed, and the time is about 2 hours. The dust remover spraying and blowing system is divided into two forms, namely on-line spraying and off-line spraying, and the pulse valve leakage inspection flow of the dust remover spraying and blowing system which is off-line spraying is as follows: the air inlet and the air outlet of the dust remover bin are closed, so that the dust remover bin does not have air flow, a worker opens the access door to enter the dust remover bin under the condition that the pulse valve is closed, and whether the pulse valve leaks can be judged by observing and sensing whether the corresponding injection pipeline has injection gas or not. The off-line blowing can check the pulse valve under the condition that the dust removing fan is not stopped, but still the air inlet and the air outlet of the dust remover bin are required to be closed, and meanwhile, the pulse valve leakage check can be carried out only by uncovering and opening the access door to enter the dust remover bin, so that a certain safety risk exists. The pulse valve leakage checking flow of the dust remover blowing system of the on-line blowing is as follows: because the dust remover is mainly changed from electric dust removal to cloth bag dust removal and has no air inlet valve, the detection of the leakage of the pulse valve of the dust remover can be accurately detected only by stopping the dust remover fan and entering the inside of the dust remover box body, but the dust remover fan can not be closed at will, so that the pulse valve leakage detection is difficult to be carried out by a dust remover blowing system for online blowing.

Therefore, a simple and convenient bag-type dust collector assembly for checking the leakage of the pulse valve is urgently needed at present, so that the time for checking the leakage of the pulse valve is shortened, and workers are prevented from entering a dust collector bin for checking, so that the safety is improved.
