Frameless mechanical automatic cycle dust cleaning bag filter

Abstract

The invention relates to a bag type dust collector which is composed of two parts, namely a frameless filter bag dust collector and a mechanical automatic cycle deashing device, wherein a dust removal chamber 10 is partitioned into a plurality of unit dust removal chambers by compartment partition plates 9; an automatic cycle mechanical deashing distributor is arranged at the upper part of the dust removal chamber; the number of air inlets of an air inlet distribution plate 7 is equal to that of the unit dust removal chambers; a fan-shaped movable air door 5 is arranged on the air inlet distribution plate 7; an arc groove 22 is formed below the air door 5, and the rest is a plane; a plane pressure touch switch 8 is communicated with a vibrator 4 for deashing in a vibrating manner; a droop is closed when a filter bag 3 is used for deashing; airflow in the filter bag is blown to be full in work; and the distributor is used for sequentially opening or closing the air inlets for deashing in an automatic cycle, and can be manually or automatically controlled. The bag type dust collector has the beneficial effects that 1 the filter area of the filter bag can be improved, and the service life of the filter bag is prolonged; 2 a dust membrane on the bottom layer is not destroyed and the dust removal efficiency is improved; 3 the investment on compressed air equipment is reduced; and 4 the bag type dust collector is simple and compact in structure and convenient to maintain.

Description

technical field [0001] The invention relates to a bag-type dust remover, in particular to a bag-type dust remover which has no frame support for the filter bag and performs mechanical automatic cycle dust removal. Background technique [0002] The standard pulse bag filter commonly seen in the market at present, arranges and installs filter bags in a dust removal room. The filter bags are supported by the filter bag frame. The following problems: (1) In the dust removal room, the dust is cleaned by pulse back blowing, and the dust after the back blowing of the filter bag will be partially directly adsorbed on other filter bags, shortening the cleaning cycle; (2), the blockage of the filter bag frame Will reduce the filter bag filter area. Patent application No. 200910135032.1 "Mechanical dust removal bag filter", adopts frameless filter bag structure design, and the filter bag implements internal filtration to filter dusty gas, which can overcome some shortcomings of standa...

Problems solved by technology

[0002] The standard pulse bag filter commonly seen in the market at present, arranges and installs filter bags in a dust removal room. The filter bags are supported by the filter bag frame. The following problems: (1) In the dust removal room, the dust is cleaned by pulse back blowing, and the dust after the back blowing of the filter bag will be partially directly adsorbed on other filter bags, shortening the cleaning cycle; (2), the blockage of the filter bag frame Will reduce the filter bag filter area

However, with a single-chamber structure, the machine cannot be shut down to clean the dust, and the dust cleaned by vibration will be sucked back to the filter bag, which will also shorten the dust-cleaning cycle

Therefore, the above technologies still have common disadvantages: (1), special compressed air equipment is required to provide air source for the pulse valve or cylinder to complete the dust cleaning work; (2), the back blowing is too large and the pulling range of the filter bag is large The excessive dust removal formed will destroy the dust film at the bottom of the filter bag and affect the filter dust removal efficiency of the filter bag

(3) The wear and tear of the filter bag and the pull tension of the filter bag are too large, which will shorten the life of the filter bag

Application No. 02219952.7 "Skeletonless Bag Dust Collector" consists of a static pressure chamber, a dust removal chamber, a collection box, reverse air blowing and dust removal, and exhaust ducts for separate chambers. Support ribs are made at the four corners of the filter bag, making the structure too complicated
