Abstract
The utility model relates to a bag-type dust collector with large filtration area, and the bag-type dust collector is used for solving the problem of relatively smaller filtration area of a cylindrical filter bag. The technical scheme is as follows: the bag-type dust collector comprises a dust collecting box body and a filter bag, wherein the filter bag is arranged in the dust collecting box body. The bag-type dust collector is characterized in that the outline of the filter bag is in a triangular prism shape and is formed by externally coating a framework in the triangular prism shape with a filter cloth outside. The filter bag of the bag-type dust collector disclosed by the utility model is designed into the triangular prism shape; and compared with the filtration area of the cylindrical filter bag, the filtration area of the filter bag can be enlarged by about 20% under the condition of same size through the improvement. Besides, the outer filter bag in the triangular prism shape is internally provided with an inner filter bag in the triangular prism shape so that the inner space of the framework is sufficiently utilized to filter dust air, so that the filtration area is further enlarged under the condition without enlarging the size of the bag-type dust collector. The bag-type dust collector is compact in structure, can be used for sufficiently utilizing the space of the dust collector and is suitable for the using occasion of the dust collector with limited space and smaller size.
Description
Technical field
The utility model relates to a kind of cleaner, particularly improves the sack cleaner of filter area under with the volume condition at dust-removing box.
Background technology
Sack cleaner is a kind of dry type dust filtration device commonly used.It is applicable to capture tiny, dry, non-fiber dust.The filter bag of sack cleaner utilizes the filtration of fabric that dusty gas is filtered, after dusty gas enters sack cleaner, large, the heavy dust of particle, because action of gravitation settles down, fall into ash bucket, contain than the gas of fine dusts by filtrate the time, dust is purified gas by detention.The formation of sack cleaner comprises dust-removing box, and filter bag is installed in the dust-removing box, and the dust-removing box bottom is provided with ash bucket.The skeleton of the existing used filter bag of sack cleaner is cylindrical, hollow, and cross section is circular, and filter cloth cover is on skeleton, and dusty gas can from being blown into outside to inside, also can be blown into filtration from inside to outside.The filter bag of this ordinary construction has the following disadvantages: 1. under the condition of identical cross-section, circular girth is less than geometries such as square, rectangle, triangles, namely with namely the girth of circle is minimum under the area condition.Therefore adopt cylindrical filter bag filter area under with the volume condition minimum, relatively increased thus dedusting pressure, increase power consumption.Because cylindrical filter bag filter area is relatively minimum, and will guarantee preferably dust removing effects, will increase filter area by the volume that increases dust-removing box, and this will consume more steel, take up room more, increase and produce and installation cost, and increased maintenance difficulty.
The utility model content
The utility model is used for solving the defective of above-mentioned prior art, provides a kind of compact conformation, with the sack cleaner of high filtration area under the volume condition.
The alleged problem of the utility model solves by the following technical programs:
A kind of sack cleaner of high filtration area, it comprises dust-removing box and filter bag, and filter bag is installed in the dust-removing box, and on the special feature: described filter bag gabarit is triangular prism shaped, and it is at triangular prism shaped skeleton outer cladding filter cloth.
The sack cleaner of above-mentioned high filtration area, described filter bag is double-decker, in the metafiltration bag internal layer filter bag is set outside, the internal layer filter bag coats inner framework by the internal layer filter cloth and consists of, two-layer filter bag is contour, coats the end filter cloth at the filter bag two ends, and wherein the bottom filter cloth is the triangle hollow structure, the bottom filter cloth is coated on outer filter bag bottom, and internal layer filter bag bottom is open state; Described top filter cloth is coated on internal layer filter bag top, and the annular section between filter bag top internal layer filter bag and outer filter bag is open state.
The sack cleaner of above-mentioned high filtration area, described internal layer filter bag are triangular prism shaped with outer filter bag form fit, and each corresponding filtering surface of two-layer filter bag is equidistant.
Linked to each other by connecting framework between the sack cleaner of above-mentioned high filtration area, described internal layer filter bag and outer filter bag.
The utility model improves for the problem of the existing cylindrical filter bag filter area of sack cleaner less, the filter bag of deduster is designed to triangular prism shaped, and this improvement can be under the condition with volume, and the filter area of more cylindrical filter bag increases approximately 20%.In addition, triangular prism shaped internal layer filter bag is set in triangular prism shaped outer filter bag, the space of skeleton inside is also fully utilized filter dirt gas, further increased filter area under the deduster volume conditions not increasing.The utility model compact conformation takes full advantage of the deduster space, is applicable to the deduster use occasion of limited space system, small volume.

Attached number in the figure is as follows: 1. ash bucket, 2. dust-removing box, 3. filter bag, 3-1. filter cloth, 3-2. skeleton, 3-3. internal layer filter cloth, 3-4. inner framework, 4. orifice plate, 5. gas outlet, 6. air inlet, 7. top filter cloth, 8. bottom filter cloth, 9. connecting framework.
The specific embodiment
Referring to Fig. 1, the utility model comprises dust-removing box 2, the gas outlet 5 of gas after the dust-removing box top is provided with and purifies, be provided with dirt gas air inlet 6 at the dust-removing box side lower part, filter bag 3 is installed in the dust-removing box, and the filter bag top is connected with orifice plate 4, and orifice plate is provided with the hole identical with the filter bag shape of cross section.
Referring to Fig. 2-5, the gabarit of the utility model filter bag 3 is triangular prism shaped, and it is at triangular prism shaped skeleton 3-2 outer cladding filter cloth 3-1.Filter bag 3 adopts double-deckers, in the metafiltration bag internal layer filter bag is set outside, is connected by connecting framework 9 between internal layer filter bag and the outer filter bag.The internal layer filter bag coats inner framework 3-4 by internal layer filter cloth 3-3 and consists of, and the internal layer filter bag is triangular prism shaped with outer filter bag form fit, and each corresponding filtering surface of two-layer filter bag is equidistant, and two-layer filter bag is contour.Two ends at filter bag 3 coat the end filter cloth, and wherein bottom filter cloth 8 is the ring-type of triangle hollow, and the bottom filter cloth is coated on outer filter bag bottom, and internal layer filter bag bottom is open state; Described top filter cloth 7 cloth are coated on internal layer filter bag top, and the annular section between filter bag top internal layer filter bag and outer filter bag is open state.
The utility model can improve filter area by adopting triangular prism shaped filter bag and double-layered filtering bag structure under with the volume condition.Referring to Fig. 1, Fig. 6, after dirt gas entered dust-removing box by air inlet 6, a part of dirt gas directly entered the internal layer filter bag by the open area of internal layer filter bag bottom, and is up through flowing out after 7 filtrations of top filter cloth; Part dirt gas is uply flowed out by the ring-type open area between filter bag top internal layer filter bag and the outer filter bag after bottom filter cloth 8 filters; Some dirt gas, is uply flowed out by the ring-type open area between filter bag top internal layer filter bag and the outer filter bag through entering behind the filter-cloth filtering between outer filter bag and the internal layer filter bag by the filter bag outside.
