Abstract
The utility model provides an external filtration type dust collecting bag which comprises a bag upper opening, an upper reinforcing layer, a bag body, a lower reinforcing layer and a bag bottom, wherein the upper reinforcing layer and the lower reinforcing layer are arranged on two ends of the bag body, parts of the reinforcing layers, which are reserved on two ends of a bag cylinder, are outwards overturned, edges are sewn with the bag body, the upper reinforcing layer is sewn with a filter bag opening wrapped with an elastic steel ring together to form a bag upper opening, and the lower reinforcing layer is sewn with the bottom of the bag together to form a bag bottom. According to the external filtration type dust collecting bag, the dust airflow washing resisting capacity and frequency shrinkage deformation resisting capacity of the bag are improved, and the accumulation of dust is removed. When the dust collecting bag works, phenomena such as cracks, damage and separation of the bag upper opening and the bag body, the bag body, the bag bottom and the bag body due to infirm sewing or sewing thread breaking can not be caused, and the dust collecting efficiency and the service life of the dust collecting bag are ensured.
Description
Technical field
The utility model relates to a kind of sack cleaner dust-removal cloth-bag, especially a kind of outside dust-removal cloth-bag with electrostatic-proof function that filters.
Background technology
The outside filtering type dust-removal cloth-bag should be furnished with the framework that the support filter bag is used in use, makes the circle bag can keep normal duty in the situation of pressurized.After dust-contained airflow enters deduster, at first enter cloth bag inside by the bag body, when dust-contained airflow streams corpus fibrosum, interception effect, the inertia effect, diffusion effect, electrostatic effect, gravitational effect etc. occur, thereby capture grit.Simultaneously, in the filter process usually be not a kind of effect in action, but multiple effect works simultaneously.The capture effect that various capture effects are play is different because of grit size, flow velocity height.Dust-contained airflow passes through fiber filter, passes the filter bag flow direction outside, and the dust of detention is attached to the outer surface of filter bag; Purified gas behind sack, the air-purifying chamber, enters in the atmosphere by aiutage after filtration.During dust-removal cloth-bag work, air-flow and grit are very large to washing away of cloth bag, and cloth bag frequently contraction distortion and violent shake when work, and the dust that accumulates in the cloth bag outer surface is come off.Therefore, just require cloth bag to have enough stitching fastness, bear for a long time and wash away with drastic deformation and can be damaged.
The employing cloth bag head of existing outside filtering type dust-removal cloth-bag is interior, bag in outside, sew up processing together; Filter bag top enhancement Layer and bottom enhancement Layer are sewn to separately with it the bag simultaneously, cause splice point too much, produce easily laying dust, the decline of cloth bag holding capacity, stitch points breakage etc., affect the filter efficiency of deduster and the service life of dust-removal cloth-bag.Can't satisfy the instructions for use of some special operation conditions, greatly, easily produce flue gas ash removal and the product-collecting of static operating mode such as Dust Capacity.
Summary of the invention
The purpose of this utility model is the problem that exists for existing outside filtering type cloth bag, and the outside filtering type dust-removal cloth-bag of a kind of technique, architecture advances is provided, and improves the anti-dust airflow scouring ability of cloth bag and resists frequent contraction distortion ability, reduces gathering of dust.Dust-removal cloth-bag when work not can because of sew up insecure or sewing thread disconnect produces cloth bag suitable for reading with at the bottom of a bag body, cloth bag bag body, the cloth bag bag with the phenomenons such as a bag body crack, breakage, disengagement, the service life of assurance efficiency of dust collection and dust-removal cloth-bag.
Described outside filtering type dust-removal cloth-bag, comprise cloth bag enhancement Layer suitable for reading, upper, bag body, lower enhancement Layer, the bag end, described upper enhancement Layer and lower enhancement Layer are positioned at the two ends of bag body, the enhancement Layer that is reserved by bag cylinder two ends respectively partly outwards overturns and edge is formed with the stitching of bag body, described upper enhancement Layer and the filter pocket mouths that is enclosed with flexible steel ring are stitched together, and to form cloth bag suitable for reading, and being stitched together at the bottom of described lower enhancement Layer and the cloth bag forms a bag end.
Further, the width of described steel rim of spring is 20-25mm, and the steel rim of spring surface is bonded with the bag bar of two parallel glass cords of parcel.
Further, described cloth bag circumferential employing four road sewing threads suitable for reading are sewed up, and the first suture is positioned at steel rim of spring edge, is used for fixed steelring; Described upper enhancement Layer uses twice sewing thread crimping to sew up by bag cylinder upset filter cloth edge with the bag body and forms; Filter bag bottom enhancement Layer is sewed up with the bag body and is formed by the bag cylinder opposite side certain-length that outwards overturns out.
Further, place enhancement Layer inboard under bag body at the bottom of the described cloth bag, being stitched together with the bag body forms a bag end.
The outside filtering type dust-removal cloth-bag that the utility model provides, it is as described below that it makes processing method:
The processing of bag opening part: the lining cloth that is surrounded by glass fiber rope is sewn into the bag bar, with glue it is bonded in the steel ring outside again; The doubling of sack cloth is sewed up, and sack external application crosspointer is sewed up.
The processing of bag body part: bag body cloth adopts three pin machines to sew up, and is sewn into the bag body of specific length, reserves the up and down length of enhancement Layer.The up and down processing of enhancement Layer part: with the outwards upset of enhancement Layer part that end opening with it the bag reserves, edge is sewed up with the bag body, makes the up and down enhancement Layer of filter bag.
The processing that divides bottom bag: the processing that the bag bottom is divided, the large end, wrapped up outside handle, single needle is sewed up.
The integral body of filter bag is processed: bag body and the bag stitching at the end, a bag end that processes, placed enhancement Layer inboard under bag body, and then sew up with the bag body; The stitching of sack and bag body places a bag body inboard to the bag head that processes, and sews up respectively processing in the edge of pressing close to steel ring and sack.
Advantage of the present utility model:
The utility model is by structure and sewing tech change, and the whole brute force of filter bag improves;
The upper enhancement Layer of filter bag and lower enhancement Layer and bag effectively reduce the upper and lower sack enhancement Layer damage and the obscission that cause because of the split stitching as Integral design;
Sew up with the bag body again behind the sack turn elder generation filter cloth parcel, can prevent turn wearing and tearing filter bag, guarantee the stitching fastness of turn;
Double-layer filter cloth is adopted at the bag end of filter bag, will sew up at the bottom of the double-ply bag first, sews up with the bag body again, guarantees the stitching fastness of a bag end, the bag end and bag body;
The employing anti-electrostatic filter cloth is made, and through antistatic agent treatment, antistatic property is outstanding, is applicable to filtrating smoke dust and the product-collecting of the large work condition environment of dust electrostatic.
