Online broken bag blocking device for pulse jet bag type dust collector

Abstract

The invention discloses an online broken bag blocking device for a pulse jet bag type dust collector. The device comprises a closing plate, a spacer and a screw rod. The closing plate and the spacer are superposed on each other and are provided with corresponding installing holes; the lower end of the screw rod is provided with a hook; the top end of the screw rod is inserted into the installing hole from the lower side of the spacer and extends out of the closing plate; and a nut is screwed at the extension end of the screw rod. A broken bag of the dust collector is rapidly blocked by using the closing plate, so online maintenance time of equipment is shortened; the equipment can run normally as soon as possible; and the accident risk of online maintenance of the dust collector is reduced. Simultaneously, the device reduces possibilities of causing fluctuation on a working condition of a dust-collecting system, affecting the running of an entire production line and causing an equipment failure due to a large amount of intake air into the dust collector after a top door is opened in an online maintenance process of the dust collector, and provides an emergency measure for the situation that no new filter bag is available for replacement on field when the bag of the dust collector is broken.

Description

Technical field: [0001] The invention mainly relates to a pulse-jet bag-type dust collector for industrial dust collection, in particular to an online bag-breaking device for a pulse-jet bag-type dust collector. Background technique: [0002] The pulse-jet bag-type dust collector for industrial dust collection has the characteristics of high dust removal efficiency, low equipment cost, small footprint, saving maintenance costs, and provides online and offline dust cleaning. The purification method of the pulse jet bag filter is the external filter type. During normal operation, the dusty gas enters each ash hopper through the air inlet, some dust particles fall into the ash hopper, and most of the rest of the dust particles rise with the airflow and enter the upper part of the ash hopper. The bag room, after being filtered by the filter bag in the bag room, the dust particles are retained on the outside of the filter bag, and the purified gas passes through the filter bag an...

AI Technical Summary

Problems solved by technology

When the bag of the dust collector is broken during use, the dust will pass through the filter bag with the airflow and be discharged from the clean air chamber, which will directly cause the discharge of the dust collector to exceed the standard. If the dust that escapes from the broken bag is not dealt with in time, it will fall to the surrounding environment In the filter bag, as the ash accumulates, the filter bag will fail

The best way to deal with the broken bag is to replace the filter bag, but to replace the filter bag, the upper injection pipe must be removed, and the broken bag is generally filled with a lot of dust, and the bag cage is difficult to extract, making it difficult and time-consuming to replace the filter bag; Moreover, since the system production is still in progress at this time, if the dust collector is dealing with high-temperature flue gas, the clean air chamber is in a high-temperature environment, and workers cannot work for a long time

In addition, when replacing the filter bag, it is necessary to open the top door of the dust collector for a long time, which will cause fluctuations in the working conditions of the entire dust collection system, affect the operation of the entire production line, and even cause equipment failure
