Abstract

A dust catcher comprises an air inlet chamber, filter bags, a filter chamber, an ash bucket, an ash-out valve, and deashing devices. An air inlet is arranged on the air intake chamber, air outlets are arranged on the filter chamber, the filter bags are positioned in the filter chamber which is separated into a plurality of layers from top to bottom, the filter bags in each layer of the filter chamber are connected in series, and each layer of the filter chamber is respectively provided with an air outlet and a deashing device. In the dust catcher of the utility model, the length of the filter bags is reduced, the top stretching force of the filter bags is greatly decreased, thereby the friction between the filter bags is avoided, and the top-down deash can be carried out from top to down under the circumstances of non-influence on dedusting work.

Description

Deduster

Technical field

The utility model belongs to mechanical environmental protection field, the deduster of a kind of industrial use specifically.

Background technology

Interior filter bag type deduster is industrial a kind of deduster commonly used, in order to reduce floor space, and handle a certain size air quantity again, the deduster that often is designed to is very high, and filter bag is very long, makes that the tension force at filter bag top is very big, and because the retractility of filter bag, the bottom easily produces gauffer, rubs between bag and the bag, and is damaged easily; Filter bag has been grown, and the time of dust landing will be grown during deashing, and deashing is inhomogeneous, and ash-removal effect is bad, and deduster can not operate as normal during deashing.

Summary of the invention

The purpose of this utility model is the defective that exists at filter bag type deduster in above-mentioned, proposes a kind of filter bag and is not easy breakage, and ash-removal effect is good, the deduster of deduster energy operate as normal during deashing.

The purpose of this utility model is achieved in that deduster of the present utility model is made up of inlet air plenum, filter bag, filter chamber, ash bucket, ash-leaking valve and deashing device, air inlet is arranged on the inlet air plenum, air outlet is arranged in the filter chamber, filter bag is in the filter chamber, the filter chamber is separated into the several layers that distributes up and down, filter bag in each layer filter chamber is connected in series, and there is air outlet and deashing device separately each layer filter chamber; Deashing device can be the blowing mouth that communicates with the filter chamber, and valve is arranged on the blowing mouth, and valve is arranged on the air outlet; Deashing device also can be the blower around filter bag.

Deduster of the present utility model is owing to be divided into the several layers of distribution up and down with the filter chamber, filter bag in each layer filter chamber is connected in series, reduced the length of each filter bag, make the tension force at each filter bag top reduce greatly, also easily with the filter bag tensioning, the bottom is difficult for producing gauffer, has avoided the friction between bag and the bag; The filter bag of each layer can adopt the filter cloth of different rerum naturas, to make full use of the filter cloth characteristic; There are separately air outlet and deashing device in each metafiltration chamber simultaneously, can successively carry out deashing from top to bottom under the situation that does not influence dedusting work.

Description of drawings

Fig. 1 is the structural representation of deduster embodiment one of the present utility model.

Fig. 2 is the structural representation of deduster embodiment two of the present utility model.

The specific embodiment

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:

As shown in Figure 1, a kind of deduster of the present utility model is by inlet air plenum 1, filter bag 2, filter chamber 4, ash bucket 11, ash-leaking valve 12 and deashing device are formed, air inlet 5 is arranged on the inlet air plenum 1, air outlet 7 is arranged in the filter chamber 4, filter bag 2 usefulness snap rings 3 are fixed in the filter chamber 4, prevent filter bag 2 excessive deformation beckets 6 on the filter bag 2, filter chamber 4 is separated into 3 layers that distribute up and down, filter bag 2 in each layer filter chamber 4 is connected in series, there is air outlet 7 and deashing device separately each metafiltration chamber 4, deashing device is the blowing mouth 10 that communicates with filter chamber 4, and valve 9 is arranged on the blowing mouth 10, and valve 8 is arranged on the air outlet 7.

In normal operation, valve 8 is opened on the air outlet 7, and valve 9 is closed on the blowing mouth 10, and dusty gas enters inlet air plenum 1 from air inlet 5, enters upper, middle and lower-ranking filter chamber 4 respectively, is discharged by air outlet 7 separately.

During deashing, at first close the valve 8 on the air outlet 7 of filter chamber, upper strata 4, open the valve 9 on the blowing mouth 10 of filter chamber, upper strata 4 simultaneously, dust on the filter bag 2 is oppositely being come off under the wind action, and the direction that comes off is consistent with the wind direction that air inlet 5 is come in, and does not have second adsorption, and that falls speeds up, after upper strata cleaning is finished, open the valve 8 on the air outlet 7 of filter chamber, upper strata 4, close the valve 9 on the blowing mouth 10 of filter chamber, upper strata 4 simultaneously.The deashing of lower floor's filter bag 2 in carrying out successively subsequently, method is the same.

As shown in Figure 2, a kind of deduster of the present utility model is made up of inlet air plenum 1, filter bag 2, filter chamber 4, ash bucket 11, ash-leaking valve 12 and deashing device, air inlet 5 is arranged on the inlet air plenum 1, air outlet 7 is arranged in the filter chamber 4, filter bag 2 usefulness snap rings 3 are fixed in the filter chamber 4, filter chamber 4 is separated into 3 layers that distribute up and down, filter bag 2 in each layer filter chamber 4 is connected in series, there is air outlet 7 and deashing device separately each metafiltration chamber 4, deashing device is the blower 13 around filter bag 2, and blower 13 is fixed on the chain gearing 14.During deashing, can carry out under the deduster operate as normal, upper, middle and lower-ranking carries out respectively from top to bottom, and the blower 13 in every layer of filter chamber 4 around filter bag 2, under the effect of chain gearing 14, moves from top to bottom, and the filter bag ecto-entad is dried.
