A kind of fixture of filter bag of dust collector
Technical field:
The utility model relates to satchel fixture technical field, relates in particular to a kind of fixture of filter bag of dust collector.
Background technology:
Pulse bag type dust collector is widely used in the purification of dusty gas, have handle that air quantity is big, floor space is little, purification efficiency is high, reliable operation, simple in structure, characteristics such as maintenance capacity is little, efficiency of dust collection can reach more than 99%.Its operation principle is generally, and during pulse bag type dust collector equipment operate as normal, dusty gas gets into ash bucket by air inlet; Because the rapid expansion of gas volume, the thicker grit of a part receives reasons such as inertia or natural subsidence to fall into ash bucket, and all the other most of grits rise with air-flow and get into the bag chamber; After filter bag filtered, grit was trapped in the outside of filter bag, and purified gas is by the inner upper box that gets into of filter bag; Enter atmosphere by valve plate hole, exhaust outlet again, thereby reach the purpose of dedusting.
Existing pulse bag type dust collector, its filter bag is fixed in the deduster through fixture.Common fixture comprises chassis, fixing port, spring and Venturi tube etc., has dismounting inconvenience, and the location is unstable; Be subjected to displacement easily, cause filter bag when jetting deashing, directly to be compressed the impact of air, have a strong impact on the service life of filter bag; And structure is complicated, and cost is higher.
The utility model content:
The purpose of the utility model is to provide to the deficiency of prior art a kind of fixture of filter bag of dust collector, its easy accessibility, and positioning stablity can effectively ensure service life of filter bag, and structure is simpler, and cost is lower.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of fixture of filter bag of dust collector, it comprises support spring, and it also comprises the support loam cake and support lower cover that is arranged in the deduster, and said support spring elasticity is connected in and supports between loam cake and the support lower cover.
Said support loam cake is provided with the recessed grain that is used to connect support spring.
Said support lower cover is provided with the edge that is used to connect support spring.
The bottom of said support lower cover is provided with nut.
Said nut is riveted on the bottom of said support lower cover.
Said support loam cake is provided with bending edges.
The utility model beneficial effect is:
The fixture of the described a kind of filter bag of dust collector of the utility model, it comprises support spring, and it also comprises the support loam cake and support lower cover that is arranged in the deduster, and said support spring elasticity is connected in and supports between loam cake and the support lower cover.Adopt the fixture of the filter bag of dust collector of said structure, need not to adopt Venturi tube, have easy accessibility, positioning stablity can effectively ensure service life of filter bag, and structure is simpler, lower-cost advantage.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side schematic view of the support loam cake of the utility model;
Fig. 3 is the vertical view of the support loam cake of the utility model;
Fig. 4 is the side schematic view of the support lower cover of the utility model;
Fig. 5 is the vertical view of the support lower cover of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Extremely shown in Figure 5 like Fig. 1; The fixture of the said a kind of filter bag of dust collector of the utility model; It comprises support spring 2, and it also comprises the support loam cake 1 and support lower cover 3 that is arranged in the deduster, and said support spring 2 elasticity are connected in and support between loam cake 1 and the support lower cover 3.
As preferred embodiment, said support loam cake 1 is provided with the recessed grain 11 that is used to connect support spring 2, and said support lower cover 3 is provided with the edge 30 that is used to connect support spring 2.This structure has the advantage of easy installation and removal, and connects fasteningly, helps guaranteeing job stability.
As preferred embodiment, the bottom of said support lower cover 3 is provided with nut 31, and further, said nut 31 is riveted on the bottom of said support lower cover 3.Nut 31 can adopt the M4 model, will support lower cover 3 and be installed on deduster when inner, is connected in nut 31 through screw tightening, can steadily install and fix and support lower cover 3.
As preferred embodiment, said support loam cake 1 is provided with bending edges 10, can effectively improve the intensity that supports loam cake 1, guarantees job stability.
The fixture of the said a kind of filter bag of dust collector of the utility model is sheathed on support spring 2 with filter bag, will support loam cake 1 and be fixedly installed in deduster inside with support lower cover 3; During work; The blowing device filter bag is blown into high speed and high pressure gas, blows the dust that is attached to the filter bag outer surface open, realizes the function of blast cleaning; Support spring 2 not only plays and supports filter bag and indeformable effect, and can also provide better vibration to make that the dust on filter bag surface is shaken effectively.The fixture of the said a kind of filter bag of dust collector of the utility model need not to adopt Venturi tube, has easy accessibility, and positioning stablity can effectively ensure service life of filter bag, and structure is simpler, lower-cost advantage.
More than toward said only be the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modification, include in the utility model patent claim.
