Description
The utility model belongs to a kind of annex of industry bag filtering systems such as carbon black, iron and steel, cement manufacturing, and it is specifically related to a kind of novel filter bag and hangs and fixture.
In carbon black, steel and cement manufacturing production process, by reclaiming product with filter bag filtration means or filtering dust to reach the purpose that reduces atmosphere and environmental pollution.It is one of key link in these industry production processes.
The normally used filter bag of carbon black industry is hung and fixture (as Fig. 9), by roof beam structure, screw thread drop hanger, spring, nut, packing ring, suspension ring on the filter bag, hang cap, go up snap ring support ring, filter bag, straight hole card and be sewn in the filter bag and have the following snap ring structure of two soft hoops of elasticity or shoulder hole and following snap ring structure at two ends and form.Its spring exists that diameter is little, silk footpath thin, fracture easily, the screw thread drop hanger kind on its top is single, and the thin flexural deformation easily of drop hanger cylindrical, plays the threaded portion easy-to-rust of tensioned positioning action and damage, cause service life low, often can only abandon it with the disposable use of filter bag.In addition, the following snap ring of filter bag is the fixing critical component of filter bag, at the following snap ring that is sewed together with filter bag and fixedly in the frame mode of card, its serviceability does not pass a test, the spring steel material that promptly descends snap ring to use, though it is elastic energy satisfies instructions for use, corrosion-resistant poor, under the corrosion of acid, alkali gas and water smoke, easily fracture because of corrosion; Use stainless steel material again because of its elasticity deficiency, shortcoming such as plastic deformation is big, filter bag is deviate from from the card hole easily.
The normally used filter bag of steel and cement industry is hung and fixture (as Figure 10), it by last roof beam structure, chain sling, dual hook, spring, suspension ring, hang cap, binding compositions such as following hoop seat and steel wire.It has structure backwardness, very complicated, is not easy to the replacing operation of other parts of rapid wear such as spring; More be not suitable for using the pneumatic somascope of filter bag directly to use numeral to determine that its filter bag gives tightening force, can only determine that filter bag gives defectives such as tightening force with artificial feel.
The purpose of this utility model, be to provide a kind of simple in structure, have corrosion-resistant, good springiness, positioning performance accurately, long service life, can be directly with the filter bag pneumatic detecting instrument directly with the tensile force that gives of digital definite filter bag, easy to operate novel filter bag is hung and fixture.
By above-mentioned design, the purpose of this utility model realizes with following technical scheme:
Novel filter bag is hung and fixture, be by roof beam structure, filter bag on the filter bag, be located at the support ring on the filter bag cylindrical and be located at the card and the filter bag lower beam frame of filter bag lower end, it is characterized in that: it also is provided with snap ring and turriform spring, drop hanger on the elasticity of being made by stainless steel material, hangs cap, jump ring and with the fixture of tension filter bag; The drop hanger bar on drop hanger top passes that roof beam structure is equipped with the turriform spring on the filter bag, its turriform both ends of the spring all has and its outer upper and lower pad support through coupling, and evenly be provided with the locating hole of plug-in mounting jump ring on the drop hanger bar, the jump ring of location turriform spring is plugged on the locating hole, its drop hanger bottom links with the suspension ring that hang on the cap that are installed in snap ring on the outer domed end of filter bag, and strain filter bag by fixture the filter bag lower end.
Above-mentioned fixture can adopt and be installed in snap ring under the identical elasticity of the filter bag bottom and above-mentioned last snap ring, and it is installed on the card shoulder hole that is solidly installed with carbon black filter bag lower beam frame.
Also can adopt in the filter bag bottom in iron and steel and the above-mentioned fixture of cement industry open type screw thread larynx hoop is housed, and be fixed in and the affixed filter bag of filter bag down on the hoop seat.
Above-mentioned drop hanger is that the open-type suspension ring then connect for the enclosed type coupling.
Above-mentioned drop hanger also can be enclosed type, and suspension ring are open-type or the connection of blasket type detachable type coupling.
Superiority of the present utility model is:
1. it is easy and simple to handle when the turriform spring of the utility model design has moulding advanced person, good springiness, stressed big, corrosion-resistant, long service life, replacing filter bag and turriform spring.Adopt drop hanger, the suspension ring of multiple structure type to strengthen serviceability, widened the scope of application, the fixture that adopt the filter bag bottom, its serviceability is good, and filter bag is difficult for deviating from from the card hole.
2. adopt the tightening force that gives of the utility model filter bag directly to adjust the filter bag tightening force, thereby to have avoided determining to give the inaccurate end that covers of tensile by artificial armrest sense in the past by the demonstration of filter bag pneumatic detecting instrument pointer with the detection numeral.
3. filter bag is fixed on the following snap ring in the shoulder hole of card, it is manufactured by the special stainless steel elastomer material, and by particular processing technology make its have good springiness, attractive in appearance, positioning performance good, not frangibility, superiority such as corrosion-resistant, its technical performance has surpassed the performance indications of home and abroad like product element.And reach world-class levels (national standard is that HV490, this material are up to HV560).
4. the utility model adopts open type screw thread larynx hoop, and the location is reliable, the filter bag size adjustable, and can arbitrarily dismantle.
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
