Abstract

The utility model relates to a tension-type fixing device of a filtering cloth bag, which comprises an elastic steel ring, a fixing part of the filtering cloth bag, a filtering part of the filtering cloth bag, a special wire basket frame and a hole plate, wherein, a structural pup joint is fixedly arranged on the hole plate l; the first radial force bearing surface of the fixing part of the filtering cloth bag is clamped on a first axial force bearing ring on the structural pup joint; the second radial force bearing surface of the fixing part of the filtering cloth bag is clamped on a second axial force bearing ring on the structural pup joint. The utility model has the advantages of simple structure, convenient assembly and disassembly, time saving, labor saving and firm fixation. The utility model can effectively prevent the filtering cloth bag from falling off and leaking dust, can extend the service life of the filtering cloth bag in multiples, and can effectively prevent from wearing rotating apparatuses.

Description

Tension type filters the cloth bag fixture

The utility model relates to the fixedly device of filter bag, is that a kind of tension type filters the cloth bag fixture, is specially adapted in the cloth-bag type dust removal by filtration system in the industries such as electric power, cement, metallurgy.

At present, in the cloth-bag type dust removal by filtration system fixedly the mode of cloth bag be to adopt: the binding method, compress method, open these three kinds of methods of staying and fix and filter cloth bag.These fixing methods of filtering cloth bags be not install numerous and diverse, effort is time-consuming, is exactly that fixing filtration cloth bag is insecure, cloth bag easily takes place leak ash or come off, and pollutes filtrations, dust pelletizing system, and the rotating machinery that weares and teares.

In view of the problem of above-mentioned existence, the purpose of this utility model is to design a kind of tension type that can firmly fix filter cloth and filters the cloth bag fixture.

The purpose of this utility model realizes by following measure: this tension type filters the cloth bag fixture and comprises flexible steel ring, filtration cloth bag standing part, filter cloth bag filtration part, special steel wire cage and orifice plate, and on orifice plate, be installed with the structure pipe nipple, filter the cloth bag standing part first radially load-carrying surface be stuck on the axial force bearing ring of first on the structure pipe nipple, filtration cloth bag standing part second radially load-carrying surface be stuck on the axial force bearing ring of second on the structure pipe nipple.

Accompanying drawing 1 filters the structural representation of cloth bag fixture for existing tension type;

Accompanying drawing 2 is a structural representation of the present utility model,

Coding in the accompanying drawing is respectively: 1 is the special steel wire cage, 2 is flexible steel ring, 3, orifice plate, 4 for filtering the cloth bag standing part, 5 is filter cloth bag filtration part, 6 is first radially load-carrying surface, and 7 is first axial force bearing ring, and 8 is the structure pipe nipple, 9 is second radially load-carrying surface, and 10 is second axial force-bearing ring.

Following structure embodiment and accompanying drawing are further described the utility model:

As shown in Figure 2, this tension type filters the cloth bag fixture and comprises flexible steel ring 2, filters cloth bag standing part 4, filter cloth bag filtration part 5, special steel wire cage 1 and orifice plate 3, and on orifice plate 3, be installed with structure pipe nipple 8, filter cloth bag standing part 4 first radially load-carrying surface 6 be stuck on the axial force bearing ring 7 of first on the structure pipe nipple 8, filtration cloth bag standing part 4 second radially load-carrying surface 9 be stuck on the axial force bearing ring 10 of second on the structure pipe nipple 8; So just form two surface and two rings that bear axial force that bear radial tension, thereby improved the stability and the durability of filtering cloth bag, reached the effect of filtering cloth bag that firmly fixes.

Before adopting the utility model, annual must the replacing filtered cloth bag 2.5 times; After adopting the utility model, annual only the replacing once filtered cloth bag; Therefore improve the service life of filtering cloth bag.

In sum, the utlity model has simple in structure, mounting or dismounting convenient and swift, time saving and energy saving, fixation Characteristics, and can effectively prevent from filtering cloth bag and come off and leak ash, significantly improve the service life of filtering cloth bag, Also wear prevention rotates equipment effectively.

Claims

1. one kind is used for fixing the tension type filtration cloth bag fixture of filtering cloth bag, comprise flexible steel ring, filtration cloth bag standing part, filter cloth bag filtration part, special steel wire cage and orifice plate, it is characterized in that being installed with on the orifice plate structure pipe nipple, and filter the cloth bag standing part first radially load-carrying surface be stuck on the axial force bearing ring of first on the structure pipe nipple, filtration cloth bag standing part second radially load-carrying surface be stuck on the axial force bearing ring of second on the structure pipe nipple.
