Description
Technical field
The utility model relates to a kind of mounting structure of filter bag, particularly relates to a kind of mounting structure 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.In gas filtration field, the filter element of most gas-filtering device mainly adopts welding or the form of thread connecting joint seals it, its sealing effectiveness depends primarily on filter element and joint surface processing, character due to flexible, porous metal forming is thin and soft, what therefore adopt flexible, porous metal material to manufacture requires higher for fabrication process condition, make mounting structure relative complex, and percent defective in process is higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sealing property better and the mounting structure of the flexible, porous metal filter bag of easily processing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The mounting structure of the utility model flexible, porous metal filter bag comprises orifice plate and filter bag, described orifice plate is provided with plate hole, described plate hole is provided with joint, the end axis of described filter bag is to being socketed on joint, described joint comprises the sealing surface arranged along filter bag radial direction and the fastening surface axially arranged along filter bag, described joint axis is to the passage having conducting plate hole and filter bag pipeline, described sealing surface is connected with orifice plate, the end of described filter bag is provided with flange, described flange is fixed on fastening surface by securing member, and described filter bag is made up of flexible, porous metal forming.The sealing surface of the described joint first forming filter bag thus that is connected with orifice plate seals, between filter bag and joint, compact siro spinning technology forms second sealing, because flexible, porous metal forming character is thin and soft, therefore the end of filter bag is needed to make flange, the filter bag outer surface that flange is corresponding with it forms bilayer and makes the sealing property of this junction better, avoid securing member directly to contact with the tube wall of individual layer filter bag and the damaged poorly sealed situation of the tube wall that causes, which thereby enhance the sealing of filter bag mounting structure.
As the further improvement of the mounting structure of above-mentioned flexible, porous metal filter bag, the first surface that described joint comprises as fastening surface is axially arranged and the second surface be connected with first surface with along filter bag, described sealing surface is connected with orifice plate upper surface, described second surface is connected with sealing surface through plate hole, thus sealing surface and fastening surface are divided the different end faces being interposed between orifice plate, improve the sealing property of mounting structure.
Further, described first surface and second surface are connected by the terrace arranged along filter bag radial direction, and described terrace forms sealing at flange place, and the junction of flange and fastening surface and ash-laden gas completely cut off by terrace opens, and further increases the sealing of this junction.
Further, be bolted between described sealing surface and orifice plate, be provided with the first seal washer between sealing surface and orifice plate, the setting of the first seal washer further increases the sealing between joint and orifice plate.
Further, the second seal washer is provided with between the filter bag outer surface of described flange position corresponding thereto, described securing member is fixed on position relative with the second seal washer on flange, and the setting of the second seal washer further increases the sealing between joint and filter bag.
Further, the two ends of described second seal washer are respectively equipped with spacing back-up ring, and spacing back-up ring makes the position of the second seal washer and securing member fix, and prevent the second seal washer and the upper and lower play of securing member.
Further, described flange is fixed on fastening surface by clip, and filter bag is firmly fixed on joint.
Further, the inner surface of described filter bag is provided with fixed mount, and described fixed mount comprises several retainer rings being connected each support bar along the support bar that filter bag axially spaced-apart is arranged with several.Because flexible, porous metal forming character is thin and soft, in order to prevent it from gas filtration process, deformation occurring, support bar being set at filter bag inner surface interval, while playing a supporting role, can not having an impact to gas filtration.
Illustrate that the utility model is described in further detail with detailed description of the invention below by way of accompanying drawing.
