Abstract
The invention discloses an anti-drop and sealing device for a filter bag of an electropulsing bag type dust collector. The anti-drop and sealing device for the filter bag comprises a cylinder, wherein the thickness of a cylinder wall is 1 to 5cm; a ring groove is arranged inside the cylinder wall; the size of the ring groove is suitable for embedding of the edge of a filter bag mouth; meanwhile, an elastic part is arranged inside the ring groove; the lower side surface of the ring groove is an inclined plane, wherein the inclined plane and a horizontal plane form an angle of 2 to 6 degrees; the edge of a ring groove opening is not a seamed edge, but is a circular arc transition; and the diameter of a circular arc is equal to the external diameter of the cylinder. The device provided by the invention has the following advantages: the filter bag can be connected with an air outlet of the electropulsing bag type dust collector in cooperation with the anti-drop and sealing device, so the connection of the filter bag and the dust collector is more firmly; sealing property is good; the problems like dust leakage from the outer edge of the filter bag and dropping of the filter bag can be completely eradicated; environment pollution is effectively reduced; and operation troubles of the dust collector are decreased.
Description
Technical field
The present invention relates to the anticreep field of sealing technology of filter bag, more particularly, the present invention relates to a kind of filter bag anticreep sealing device of electric pulse sack cleaner.
Background technology
The filter bag of electric pulse sack cleaner used be at present directly be sleeved on dust remover roof porous plate above, as shown in Figure 1, filter bag 2 is directly sleeved on above porous plate 1, but because filter bag 2 and the contact area of porous plate 3 are little and cannot be adjacent to, and dust absorption fan also must run during deduster operation, filter bag 2 can ceaselessly swing under the impact of powerful wind speed and frequent pulse, filter bag 2 and porous plate 1 contact position is very easily caused to leak ash, leak an ash part and entered contaminated environment in air by blower fan sucking-off, another part then falls in filter bag 2.Along with the prolongation of deduster running time, in filter bag, dust stratification can get more and more, and filter bag weight also constantly increases, and finally cause whole filter bag to come off because of overweight, equipment cannot normally run.
Summary of the invention
An object of the present invention is to solve at least the problems referred to above and/or defect, and the advantage will illustrated at least is below provided.
A further object of the invention is just to provide a kind of filter bag anticreep sealing device of electric pulse sack cleaner, make filter bag can be connected on the exhaust outlet of electric pulse sack cleaner with this anticreep sealing device, filter bag is made to be connected more firm with the exhaust outlet of deduster, good airproof performance, filter bag outer edge can be stopped completely leak ash and filter bag and the problem such as to come off, effectively reduce the operation troubles of environmental pollution and minimizing deduster.
In order to realize according to these objects of the present invention and other advantages, provide a kind of filter bag anticreep sealing device of electric pulse sack cleaner, described filter bag anticreep sealing device is cylinder, described cylindrical wall thickness is 1-5cm, annular groove is provided with in described cylindrical wall, described annular groove size is suitable for filter pocket mouths edge and embeds, and be provided with elastomeric element in described annular groove, the downside of described annular groove is inclined-plane, inclined-plane becomes the angle of 2-6 degree with horizontal plane, the opening edge of described annular groove is not seamed edge but arc transition, arc diameter equals described outside diameter of cylinder, described filter bag is the filter bag of sack band elastic ring, and sack limit has multiple edge protruded towards periphery, the upper flange of described cylinder is evenly provided with the screw that radial direction is got through, and be furnished with corresponding screw rod.
Preferably, wherein, the lower flange of described cylinder is evenly provided with the screw axially got through, and is furnished with corresponding screw rod.
Preferably, wherein, the annular groove in described cylindrical wall has 2.
Preferably, wherein, except the described edge near filter pocket mouths does not embed except in described annular groove, edge described in all the other is good ingeniously can be embedded in described annular groove.
Preferably, wherein, described cylinder is threaded with the exhaust outlet of deduster or welds.
The present invention at least comprises following beneficial effect: because filter bag anticreep sealing device is be provided with annular groove in cylindrical wall, and annular groove size is suitable for the embedding of filter pocket mouths edge, therefore can wrap benefit filter bag, very closely can block filter bag again; Owing to being provided with elastomeric element in annular groove, therefore effectively can strengthen the compactness of filter bag and annular groove, reduce filter bag outer edge and leak ash; Downside due to annular groove is inclined-plane, and inclined-plane becomes the angle of 2-6 degree with horizontal plane, and therefore anticreep effect is fine, effectively stops filter bag and comes off, and can also contribute to filter bag and this anticreep sealing device dismounting; Because the opening edge of annular groove is not seamed edge but arc transition, arc diameter equals described outside diameter of cylinder, therefore when deduster runs, can not be damaged by its fillet of available protecting, can contribute to dismounting again.Owing to selecting filter bag to be the filter bag of sack band elastic ring, and sack limit there is multiple edge protruded towards periphery, both just can embed the annular groove of this anti-drop device by extruding sack elastic ring, easy disassembly and enhanced leaktightness and fastening.Owing to the upper flange of cylinder being evenly provided with the screw that radial direction is got through, and be furnished with corresponding screw rod, and figure below edge of cylinder is evenly provided with the screw axially got through, and be furnished with the structures such as corresponding screw rod, can promote that filter bag is connected with this anticreep sealing device more closely with firm further.Owing to not embedding except in described annular groove except the described edge near filter pocket mouths, edge described in all the other is good ingeniously can be embedded in described annular groove, therefore can be connected with this anticreep sealing device more closely and firmly, filter bag and this anticreep sealing device dismounting can also be contributed to by filter bag.
