Abstract
The utility model discloses a filter cloth for gaseous dust removal, this filter cloth includes fixed connection's first fabric layer, second fabric layer and third fabric layer in proper order, and the aperture in the first fabric layer is greater than the aperture in the second fabric layer, and the aperture in the second fabric layer is greater than the aperture in the third fabric layer. This filter cloth has longer life.
Description
Technical field
The utility model relates to a kind of filter cloth, specifically, relates to a kind of filter cloth for dedusting.
Background technology
At present, in industrial dedusting field, filter bag is a kind of common cleaner.Conventional filter bag comprises skeleton and filter bag body.Skeleton is for supporting filter bag body.Gas containing dust realizes dedusting by filter bag body.Dust is attached on filter bag body.Filter bag body is made up of filter cloth.In prior art, the filter bag body of same style is made up of a kind of filter cloth of specification usually.Because the aperture in this filter cloth is very little, so good filter effect can be played.But the filter cloth in too small aperture is easily subject to the blocking of dust, not easily extend its service life.
Summary of the invention
technical problem:technical problem to be solved in the utility model is: provide a kind of filter cloth for dedusting, to improve the service life of filter cloth.
technical scheme:for solving the problems of the technologies described above, the technical scheme that the utility model embodiment adopts is:
A kind of filter cloth for dedusting, this filter cloth comprises the first tissue layer, the second tissue layer and the 3rd tissue layer that are fixedly connected sequentially, aperture in first tissue layer is greater than the aperture in the second tissue layer, and the aperture in the second tissue layer is greater than the aperture in the 3rd tissue layer.
As a kind of preference, be provided with the first groove in the first described tissue layer, in the second tissue layer, be provided with the second groove, in the 3rd tissue layer, be provided with the 3rd groove.
As a kind of preference, the bottom of the first described groove communicates with the outer wall of the first tissue layer.
As a kind of preference, the bottom of the second described groove communicates with the bottom of the first groove.
As a kind of preference, the bottom of the 3rd described groove communicates with the bottom of the second groove.
beneficial effect:compared with prior art, the utility model has following beneficial effect: the filter cloth of the present embodiment is provided with the first tissue layer, the second tissue layer and the 3rd tissue layer.Aperture in first tissue layer is greater than the aperture in the second tissue layer, and the aperture in the second tissue layer is greater than the aperture in the 3rd tissue layer.First tissue layer contacts with dusty gas at first.Dusty gas, through after the first tissue layer, enters the second tissue layer.Dusty gas, through after the second tissue layer, enters the 3rd tissue layer.In whole process, the dust that in dusty gas, particle diameter is larger is tackled by the first tissue layer.The medium sized dust of particle diameter is tackled by the second tissue layer.The minimum dust of particle diameter is tackled by the 3rd tissue layer.The unified tissue layer adopting aperture less of comparing makes filter cloth, and the filter cloth of the present embodiment filters the dust of different-grain diameter at many levels, is conducive to the service life of improving whole filter cloth.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model embodiment.
Have in figure: the first tissue layer 1, second tissue layer 2, the 3rd tissue layer 3, first groove 101, second groove 201, the 3rd groove 301.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of filter cloth for dedusting of the utility model embodiment, this filter cloth comprises the first tissue layer 1, second tissue layer 2 and the 3rd tissue layer 3 that are fixedly connected sequentially, aperture in first tissue layer 1 is greater than the aperture in the second tissue layer 2, and the aperture in the second tissue layer 2 is greater than the aperture in the 3rd tissue layer 3.
The filter cloth of said structure, is provided with the treble cloths layer that aperture is different.Wherein, the aperture in the first tissue layer 1 is greater than the aperture in the second tissue layer 2, and the aperture in the second tissue layer 2 is greater than the aperture in the 3rd tissue layer 3.First tissue layer 1 is positioned at outermost, contacts at first with dusty gas.Second tissue layer 2 is positioned at middle part.Dusty gas, through after the first tissue layer 1, enters the second tissue layer 2.3rd tissue layer 3 is positioned at most external.Dusty gas, through after the second tissue layer 1, enters the 3rd tissue layer 3.In whole process, the dust that in dusty gas, particle diameter is larger is tackled by the first tissue layer 1.The medium sized dust of particle diameter is tackled by the second tissue layer 2.The minimum dust of particle diameter is tackled by the 3rd tissue layer 3.The unified tissue layer adopting aperture less of comparing makes filter cloth, and the filter cloth of the present embodiment filters the dust of different-grain diameter at many levels, is conducive to the service life of improving whole filter cloth.
As preference, be provided with in the first described tissue layer 1 in first groove 101, second tissue layer 2 to be provided with in the second groove the 201, three tissue layer 3 and be provided with the 3rd groove 301.In filter process, dust may be embedded in the hole of the first tissue layer 1, blocking space.This preference arranges the first groove 101.Like this, be embedded to the dust in the first tissue layer 1 hole, under the impact of air-flow, lose and fall in the first groove 101, thus make the first tissue layer 1 hole keep unimpeded, extend its service life.Equally, the second groove 201 is set, the dust that can will be embedded in the second tissue layer 2 hole, under the impact of air-flow, loses and fall in the second groove 201, make the second tissue layer 2 hole keep unimpeded, extend its service life.3rd groove 301 is set, the dust that can will be embedded in the 3rd tissue layer 3 hole, under the impact of air-flow, loses and fall in the 3rd groove 301, make the 3rd tissue layer 3 hole keep unimpeded, extend its service life.
As preference, the bottom of the first described groove 101 communicates with the outer wall of the first tissue layer 1.Due to may dust be collected in the first groove 101, therefore, the outer wall of the bottom of the first groove 101 with the first tissue layer 1 is communicated, thus the dust making to be arranged in the first groove 101 in the impact current downflow of air-flow outside the first tissue layer 1.Equally, the bottom of the second described groove 201 communicates with the bottom of the first groove 101, and the dust making to be arranged in the second groove 201, and to flow to outside the first tissue layer 1 with the dust in the first groove 101 to the first groove 101 in the impact current downflow of air-flow.The bottom of the 3rd described groove 301 communicates with the bottom of the second groove 201,
The dust making to be arranged in the 3rd groove 301, and to flow in the first groove 101 with the dust in the second groove 201 to the second groove 201 in the impact current downflow of air-flow, then flow to outside the first tissue layer 1 from the first groove 101.
The above is only optimal technical scheme of the present utility model; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
