Description
[technical field]
The utility model relates to a kind of sack cleaner, especially relates to the filter bag fixed structure of outer-filtering bag-type deduster.
[background technology]
The structure of outer-filtering bag-type deduster generally includes the dust-removing box that is formed through the flange connection by the upper, middle and lower casing, and the card, filter bag and the annex thereof that are arranged in the dust-removing box inner chamber, and card is arranged on the top of inner chamber, is used for fixing filter bag opening; Annex comprises that skeleton, auxiliary fixedly filter pocket mouths are in the fixture in card hole etc.At present, continuous development along with science and technology, the sack cleaner structure has also had great changes, but, adopt the fixedly but not change all the time of structure of filter bag opening of card, therefore, this structure had become the bottleneck that limits this industry development already: the one, and card is made the required precision height, processing difficulties, during making, need to adopt accurate automatic gas cutting machine could on the monoblock steel plate, cut out the satisfactory fixing hole of using, and adopt general hand-held cutter cuts easy deformation, do not reach required precision at all, not only the process equipment investment is big, and time-consuming trouble, and the waste of cutting clout is serious.The 2nd, sack is fixing loaded down with trivial details, and though that fixed form has is multiple, all there is the problem of this respect in the poor reliability that wastes time and energy.Adopt the spring steel plate structure, making filter pocket mouths trouble, want earlier spring steel plate to be made turn, the rubber seal that outside turn, has groove then on the pad, again filter pocket mouths pass in the turn back outside rubber seal, turn back collapse tight, dead with sewing machine seam at last, pass the card hole after will having the filter pocket mouths compression of turn during assembling, utilize the reset force of turn and fix.Adopt filter bag seat or short tube structure, then need to prick head, prick hoop, jag etc. with bag, the manual colligation of the employing in one hole, a hole, the efficient that wastes time and energy is low.The 3rd, adopt card fixedly can only fix one in the every hole of filter bag, filter bag and filter bag split are individual components, and the dust-removing box availability is low, and the waste resource is difficult to adapt to development trend.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of new outer-filtering bag-type deduster, this bag dust collector has special filter bag fixed structure, not only fixedly filter bag is convenient, but also be particularly suitable for the stationary positioned of disjunctor filter pocket mouths, thus can greatly simplify the manufacture craft of bag dust collector, improve the dust-removing box availability, reduce production costs, help promoting the development of whole industry.
The technical scheme that realizes above-mentioned purpose is as follows: this outer-filtering bag-type deduster, comprise by upper box, middle casing and lower box connect the dust-removing box that forms through flange, and the filter bag and the annex thereof that are arranged in the dust-removing box inner chamber, annex comprises the fixation kit that is used for fixing filter bag opening, be arranged on the skeleton in the filter bag inner chamber, it is characterized in that: described fixation kit is by the horizontal sack fixed frame that is arranged on dust-removing box inner chamber top, and match with the sack fixed frame, the spill fastener that is used for fixing filter bag opening constitutes, be fixed on the dust-removing box inwall around the described sack fixed frame, sack fixed frame middle part has the multiple row sack and admits groove, and sack admits the peristoma of groove to be with the vertical lock of circle wall; Described filter bag is the disjunctor cloth bag of Bag chain structure, the bottom filter cylinder of disjunctor cloth bag or disjunctor or split, and the top of disjunctor cloth bag is public sack, the bag limit of public sack is pressed on the vertical lock wall by described spill fastener card.
As to technique scheme further replenish and perfect, the utility model also has following additional technical feature.
It is three-back-shaped that described spill fastener is monoblock type, and three-back-shaped monolateral cross sectional shape is " recessed " font, and height, the thickness of the groove depth of " recessed " font, width and described vertical lock wall are complementary.
Described spill fastener is the press strip that a cross sectional shape is " recessed " font, and height, the thickness of the groove depth of " recessed " font, width and described vertical lock wall are complementary.
Beneficial effect: compared with prior art, the utility model is used with the dust-removing box inwall and is become whole sack fixed frame formula structure to substitute fixedly filter bag of existing card, the one, overcome card and made required precision height, processing difficulties, during making, need to adopt accurate automatic gas cutting machine could on the monoblock steel plate, cut out the satisfactory fixing hole of using, and adopt general hand-held cutter cuts easy deformation, do not reach the technical problem of required precision, it is then very convenient to make sack fixed frame of the present utility model and spill fastener at all; The 2nd, assemble very simply, as long as utilize the spill fastener that the filter bag checkpost is pressed on the vertical lock wall around the sack fixed frame groove, dismounting, maintenance etc. are very convenient; The 3rd, help realizing arranging the Bag chain structure, make the processing of filter bag also become simple and convenient, need on filter pocket mouths, not process turn and rubber seal are set, adopt bag to prick head during assembling again, prick hoop, jag etc., the manual colligation in one hole, one hole, the development trend that adapts to deduster, the 4th, adopt the Bag chain structure, can increase substantially the availability of dust-removing box.In a word, this outer-filtering bag-type deduster, processing is simple, and is easy to make, and processing sewing that need not high-precision process equipment, especially cloth bag is more simple, has both saved raw material and has reduced production cost, has alleviated workpeople's labour intensity again.
