Grinding dust bag filter structure

Grinding dust removal workbench, the structure composition of bag filter with 4 grinding dust collector workbench, consists of frame, body, filter bag, bag filter soot cleaning device, compressed air device, differential pressure device and electric control device. Framework: the framework of bag filter is composed of beam and column and brace frame design of the point is to have sufficient strength and rigidity support housing, grey heavy load and the maintenance of activities, and prevent encountered special circumstances, such as earthquake, wind and snow disaster is not damaged. Box, bag filter in the box body is divided into filter bag room and clean room of two parts, two rooms separated by flower board. Mainly in the design of the enclosure wall plate and the plate. Body shape with various shapes, such as round, square, rectangle. Different shape is determined by the dust collector process conditions and the filter size, among them the majority with a rectangle. Soot cleaning device: the main difference between different filter in the ash removal device. Filter bag dust collector workbench filter polishing dust removal workbench, dust filter bag: installation of counter blowing bag-type dust filter bag installation and flow, gas inside the bag filter bag is in cylindrical. The lower end of the filter bag is fixed on the plate sleeve, the upper end fixed on the cap. Process gas flow from the lower part of filter bag opening, while rising bifurcate filtering. Be the dust filter, adhesion, deposition inside the filter pocket, formed a kind of dust layer; Clean gas flow to the filter bag outside, ventilation pipe to export; Cap at the top of the filter bag is fixed on the hanger, hanger by maintaining proper tension of the spring is fixed on the ceiling. Sets the inner diameter of filter bag to D, effective height of H, the filter bag handle gas quantity Q need number n, the filter area A = nDH. Filtering of D is in commonly 125 ~ 450 mm in diameter, height H within 2 ~ 12 m. In order to meet the filter requirements, its height and diameter ratio H/D take 4 ~ 40. Filter bag materials depends on the degree of acid and alkali treatment of gas temperature, gas, dimensional stability, permeability and the service life of filter pocket and so on. The service life of filter bag and the conditions of use and related materials, short a few months, the elderly a few years.

are present in just about every facet of modern life.
