Abstract
The invention discloses a negative-pressure simulating device for detecting the deashing property of a bag type dust collector, belonging to the field of bag type dust collector deashing property detecting devices. The negative-pressure simulating device comprises a draught fan, a negative-pressure box and a fixing device, wherein the draught fan is connected with the negative-pressure box through a pipeline; a filter bag is fixed on the fixing device; the opening end of the filter bag is arranged on a tubesheet; and the tubesheet is arranged on the opening part of the negative-pressure box. By adopting the draught fan, the invention can more really and accurately simulate the working state of the filter bag in the bag type dust collector through negative pressure which is generated by a negative pressure cavity and is similar to the negative pressure generated under the actual work condition of the filter bag, thereby enabling a test result to be more approximate to the actual deashing intension of the filter bag; the invention can more accurately test the deashing property of the filter bag, meet the need of production, enhance the quality of products and prolong the service life of the filter bag; in addition, the negative-pressure simulating device has simple structure, small investment and both very convenient installation and movement.
Description
[technical field]
The present invention relates to device that deashing property of bag type dust collector is detected, relate in particular to a kind of negative-pressure simulating device.
[background technology]
At present, the use of sack cleaner is increasingly extensive.And filter bag is as its core component, and the economy of its life-span to sack cleaner has direct relation.Wherein, the life-span of the intensity of deashing and frequency and filter bag is closely related, and the research of filter bag ash removal pattern is just become very urgent.
All be that filter bag both sides differential pressure is to test under the state of 0Pa in atmosphere at present to the test of filter bag differential pressure that both sides produce when being compressed the air deashing and vibration acceleration.And the actual operating state of filter bag in sack cleaner is in certain negative pressure (1000Pa usually) work down.This makes the result of test produce bigger error.
[summary of the invention]
Purpose of the present invention solves the problems of the prior art exactly, proposes a kind of negative-pressure simulating device for detecting deashing property of bag type dust collector, can simulate the actual operating state of filter bag, tests out the deashing property of sack cleaner more accurately.
For achieving the above object, the present invention proposes a kind of negative-pressure simulating device for detecting deashing property of bag type dust collector, comprise air-introduced machine, negative pressure box, fixture, described air-introduced machine is connected to negative pressure box by pipeline, described filter bag is fixed on the fixture, the openend of filter bag is installed on the card, and described card is installed to the peristome of negative pressure box.
As preferably, also be provided with the throttling sheet on the described negative pressure box.Regulate the vacuum magnitude that negative pressure box produces by the throttling sheet, with truer, simulate the actual condition of filter bag exactly.
As preferably, the total head of described air-introduced machine is 2000～3000Pa.Can satisfy the needs of negative pressure simulation.
As preferably, the nominal air delivery of described air-introduced machine is 500～1000m
3/ h.Can satisfy the needs of negative pressure simulation.
Beneficial effect of the present invention: the present invention adopts air-introduced machine, similar negative pressure when producing with the filter bag actual condition by negative pressure box, can simulate the state of filter bag when in sack cleaner, working truer, exactly, make test result more near the actual deashing intensity that is subjected to of filter bag, can test out the deashing property of sack cleaner more accurately, meet the needs of production, improve product quality, prolong life-span of the filter bag.This apparatus structure is simple, small investment, installation and mobile all very convenient.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 detects the structural representation of using negative-pressure simulating device for filter bag of the present invention.
[specific embodiment]
As shown in Figure 1, filter bag detects uses negative-pressure simulating device, comprise air-introduced machine 1, negative pressure box 3, fixture 5, described air-introduced machine 1 is connected to negative pressure box 3 by pipeline 2, described filter bag 6 is fixed on the fixture 5, the openend of filter bag 6 is installed on the card 4, and described card 4 is installed to the peristome of negative pressure box 3.Also be provided with throttling sheet 7 on the described negative pressure box 3, the negative pressure that filter bag 6 needs during test can be adjusted the vacuum magnitude that bag-type dusting negative pressure box 3 produces by the throttling sheet 7 that adjustment is located on the negative pressure box 3, with truer, simulate the actual condition of filter bag 6 exactly.The total head of described air-introduced machine 1 is 2000～3000Pa, and nominal air delivery is 500～1000m
3/ h can satisfy the needs that negative pressure is simulated.This device can access between 0～2m/min cloth bag filtration velocity arbitrarily.
The foregoing description is to explanation of the present invention, is not limitation of the invention, any scheme after the simple transformation of the present invention is all belonged to protection scope of the present invention.
