Abstract
The utility model discloses a seal structure of flexible porous metal filter bag, including the orifice plate that is equipped with the diaphragm orifice, be fixed with the filter bag that the flexible porous metal forming constitutes on the diaphragm orifice, diaphragm orifice a week is equipped with protruding structure along the filter bag axial, the filter bag tip is equipped with and turns over a structure of rolling over to its surface, it is fixed with the cooperation of protruding structure to turn over a structure. Because flexible porous metal forming nature is thin and soft, can fold or buckle it, the filter bag tip that constitutes the flexible porous metal forming is fixed in the protruding structure on the orifice plate through turning over a cooperation, will turn over a structure from this and be in with protruding structural connection that the ash -laden gas is isolated to come, has guaranteed the leakproofness of flexible porous metal filter bag from this, and the while also makes it fix on the orifice plate, and whole seal structure of flexible porous metal filter bag is simple, simple to operate.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of filter bag, particularly relates to a kind of hermetically-sealed construction of flexible, porous metal filter bag.
Background technology
The applicant discloses a kind of flexible, porous metal forming in Chinese patent literature CN104588662A, and this flexible, porous metal forming is can the thin slice that even folds of free bend, is formed the filter element of the shape such as template or cast according to practical application.Flexible, porous metal forming is thinner compared with existing filter element material, more soft, and in chemoresistance, material irreversible membrane fouling repellence, mechanical strength etc., there is stronger advantage, the filter bag use flux making it form thus is large, working strength is high, longer service life, and the filter bag that flexible, porous metal forming is formed needs to carry out sealing to its tube end equally and installs when embody rule.Most gas-filtering device filter bag adopts welding or the form of thread connecting joint to carry out sealing to it and installs, the present inventor finds when studying, according to the above-mentioned character of flexible, porous metal forming, existing sealing mounting means cannot be applicable to the filter bag that flexible, porous metal forming is formed, based on above-mentioned background, the present inventor have developed a kind of hermetically-sealed construction of flexible, porous metal filter bag.
Utility model content
Technical problem to be solved in the utility model is the hermetically-sealed construction providing a kind of sealing property good flexible, porous metal filter bag.
In order to solve the problems of the technologies described above, the utility model is realized by following technical scheme:
The hermetically-sealed construction of the utility model flexible, porous metal filter bag, the filter bag comprising orifice plate and be made up of flexible, porous metal forming, described orifice plate is provided with plate hole, plate hole is axially arranged with bulge-structure in one week, described filter bag end is provided with the turnover structure turned down to its outer surface, and described turnover structure coordinates fixing with bulge-structure.Because flexible, porous metal forming character is thin and soft, can carry out folding or bending to it, filter bag end flexible, porous metal forming formed coordinates the bulge-structure be fixed on orifice plate by turnover, thus turnover structure is connected with bulge-structure and is in that ash-laden gas is isolated to come, ensure that the sealing of flexible, porous metal filter bag thus, also make it be fixed on orifice plate, the hermetically-sealed construction of whole flexible, porous metal filter bag is simple, easy for installation simultaneously.
Further, described bulge-structure is arranged at plate hole upper surface one week, described turnover structure is fixed on bulge-structure outer surface one week through plate hole by securing member, filter bag end is through plate hole, by securing member, turnover structure is fixed on bulge-structure, the zones of different making hermetically-sealed construction and filter bag main body be in orifice plate thus to split, comes ash-laden gas and sealing segmentation of structures thus, further increases the sealing property of the hermetically-sealed construction of filter bag.Particularly, described bulge-structure outer surface is provided with groove in one week, described securing member is clip, described clip is fixed on position corresponding with groove on bulge-structure, utilize flexible, porous metal forming thin and the performance of softness, adopt clip mode to be fixed on bulge-structure by turnover structure, filter bag is more firmly fixed on orifice plate; Clip fixed position is corresponding with groove, makes the better tightness of clip part thus.
Further, described inside grooves is provided with sealing ring, further increases the sealing property of hermetically-sealed construction thus.
Particularly, described bulge-structure is axially be welded in the plate hole short tube of a week along filter bag, and described short tube is connected one end with orifice plate and is provided with seam, and its other end is provided with rounding.Seam makes short tube more firmly be welded on orifice plate, because filter bag is made up of the thin and flexible, porous metal forming of softness, therefore rounding be arranged so that turnover structure and short tube agree with more.
Filter bag inside is provided with fixed mount, described fixed mount comprises end winding support structure and supporting construction, described end winding support structure is withheld and is installed on turnover structure, described supporting construction is close to the inner surface of filter bag, the filter bag that flexible, porous metal forming is formed is thinner and soft due to it, therefore in order to prevent filter bag from the process used, deformation occurring, affects filter effect, therefore playing support filter bag wall on the one hand by arranging fixed mount, preventing the effect that it is out of shape; Play the effect of fastening turnover structure on the other hand, further increase the sealing property of filter bag hermetically-sealed construction thus.Particularly, described end winding support structure is circular ring cover, described supporting construction comprises several and is arranged at support bar on filter bag inner surface along filter bag axially spaced-apart and several connect the support ring of each support bar, between adjacent supports bar, interval is arranged and interval setting between adjacent supports ring, can not have influence on the strainability of filter bag thus.
Illustrate below by way of accompanying drawing and detailed description of the invention the utility model is further described.
