Automatic leak-checking device for cloth bag

Abstract

An automatic bag leak detection device, which can automatically detect and display the damaged bags of the square blowback and pulse bag filter on the instrument, and can automatically alarm, allowing the operator to record the number of damaged bags, including The longitudinal step mechanism includes a movable chassis and a longitudinal step cylinder; a horizontal step mechanism is installed on the movable chassis, and the horizontal step mechanism includes a horizontal step cylinder, rack and gear; The sampling mechanism includes a sampling wheel, and the sampling mechanism also includes a sampling tube. The sampling tube is divided into two parts, which are respectively located inside and outside the dust collector. The present invention extracts gas samples from the mouth of each cloth bag through the linkage of the longitudinal step mechanism, the horizontal step mechanism and the sampling mechanism, and allows the gas samples to pass through the smoke concentration automatic detection mechanism for detection and alarm. The number automatic display mechanism automatically shows which bag is damaged.

Description

technical field [0001] The invention relates to a detection device, in particular to an automatic bag leak detection device for detecting whether the bag is damaged in a bag type dust collector. Background technique [0002] At present, the bag filter includes rotary bag filter, square back blowing and pulse bag filter. During use, the bags of the bag filter are sometimes damaged. If one of the bags is damaged (such as a small hole) , it will cause the emission concentration of this dust collector to exceed the standard, and it is necessary to check and replace the bag, but the existing technology cannot know and judge which bag is damaged, so it has to be shut down for inspection one by one or a large number of replacements, causing unnecessary trouble and waste of human and material resources. [0003] The applicant once solved this problem in two patent applications with application numbers 021223319 and 2004200976504, but this solution is only applicable to the rotary b...

Problems solved by technology

[0002] At present, the bag filter includes rotary bag filter, square back blowing and pulse bag filter. During use, the bags of the bag filter are sometimes damaged. If one of the bags is damaged (such as a small hole) , it will cause the emission concentration of this dust collector to exceed the standard, and it is necessary to check and replace the bag, but the existing technology cannot know and judge which bag is damaged, so it has to be shut down for inspection one by one or a large number of replacements, causing unnecessary trouble waste of human and material resources

[0003] The applicant once solved this problem in two patent applications with application numbers 021223319 and 2004200976504, but this solution is only applicable to the rotary bag filter, not to the square blowback and pulse which account for 80% of the market Baghouse
