Abstract

The utility model discloses a combined type filter bag. The upper portion of the filter bag is circular or flat while the lower portion of the filter bag is conical. The combined type filter bag has the circular or flat upper portion and the conical lower portion which are combined with each other, mainly resolves problems that circular and flat filter bags are not thorough in dust cleaning and easy to cause secondary dust raising, conical filter bags have smaller filter areas, and the like, combines advantages of the circular or flat filter bags and the conical filter bags, not only guarantees a certain filter area, but also is favorable for cleaning dust, reduces dust cleaning energy consumption, decreases abrasion of the bottom of the bag and prolongs the service life.

Description

The combined type filter bag

Technical field

The utility model relates to a kind of combined type filter bag.

Background technology

Sack cleaner has good capture effect to industrialness dust and flue dust, is of wide application.But the technical problem underlying of its existence has: life-span of the filter bag is short, deashing is not thorough, filtration resistance is big, be easy to generate reentrainment of dust etc., has influenced the raising of efficiency of dust collection.In addition, the sack cleaner compact conformation, bag bag spacing is less, and bag easily gouging abrasion between the end influences life of bag filter.

A kind of filter bag is arranged in the prior art, and the whole piece filter bag is circle or flat.This filter bag filter area is big, simple in structure, but deashing is not thorough, is easy to generate reentrainment of dust, and bag bag spacing is less, bag easily gouging abrasion between the end, the service life of shortening filter bag.Also have a kind of filter bag, the whole piece filter bag is taper (seeing patent 201295572).This filter bag ash removal is effective, and bag bag spacing is big, but circle or flat filter bag are little a lot of relatively for filter area.

Problem and the little problems of taper filter bag filter area such as rounded pocket and flat filter bag ash removal are not thorough in order to solve, generation reentrainment of dust, the inventor has developed a kind of novel filter bag, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of combined type filter bag, has both guaranteed certain filter area, helps deashing again, reduces resistance of the filter bag, prolongs life-span of the filter bag.

To achieve these goals, the technical solution of the utility model is:

A kind of combined type filter bag, filter bag top are circle or flat, and the bottom is taper.

After adopting said structure, the utility model combines circle or flat with taper, mainly be that solution circle and flat filter bag ash removal are not thorough, easily produce problems such as reentrainment of dust and cone type filter bag filter area be less, combine the advantage of circle or flat filter bag and cone type filter bag, both guaranteed certain filter area, be beneficial to deashing again, reduce the deashing energy consumption, and reduce the wearing and tearing of the bag end, prolong life of bag filter.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a kind of sectional view of Fig. 1;

Fig. 3 is the another kind of sectional view of Fig. 1.

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of combined type filter bag that the utility model discloses, filter bag top 1 is circular (as shown in Figure 2) or flat (as shown in Figure 3), bottom 2 is taper dead angle (as shown in Figure 1).This design has kept circular and the big advantage of flat filter area on unit space, introduced cone type filter bag, increased bag end spacing, reduced bag bag collision friction, the structure of " up big and down small " simultaneously, the dust that bag adheres to when helping deashing comes off, peels off under deadweight and the effect of winding-up air-flow, significantly reduced the deashing energy consumption, make deashing more thorough, and reduce a bag spirit stream rate of climb, reduced reentrainment of dust, improved ash-removal effect, reduce resistance of the filter bag, prolong life-span of the filter bag.

It below only is preferred implementation of the present utility model; it is not qualification to protection domain of the present utility model; key technology all and of the present utility model does not have to produce difference in essence, to the deduction or replace of above-mentioned embodiment, all should be regarded as falling within the protection domain of this case.

Claims

1. combined type filter bag, it is characterized in that: filter bag top is circle or flat, the bottom is taper.
