Abstract
The utility model discloses a fan-shaped net cover of a filter, belonging to the technical field of filter accessories. The fan-shaped net cover is characterized by comprising two metal nets and two anti-fatigue edges around the metal nets, wherein the metal nets and the anti-fatigue edges are sewn together through first sewing threads; the external sides of the two anti-fatigue edges are sewn through second sewing threads; adhesive layers are arranged along the surfaces of the sewing threads of the metal nets and the anti-fatigue edges; the adhesive layers made of rubber materials, the metal nets and the anti-fatigue edges are heated to vulcanize together; and the adhesive layers integrally connect the metal nets and the anti-fatigue edges in the swelling process of the metal nets to prevent joints of the metal nets and the anti-fatigue edges from bending, protect the first sewing threads and prevent the sewing threads from being corroded.
Description
Technical field
The utility model belongs to filter accessory technical field, relates in particular to the fan-shaped net of a kind of filter.
Background technology
Development along with Coal Chemical Engineering Industry, the range of application of filter is more and more wider, demand as the fan-shaped net of filter of filter auxiliary accessories is more and more, the present main dual mode of the fan-shaped net of filter that uses, one, the net periphery adopts welding, the fan-shaped net fatigue performance of the filter that this kind method is made is poor, has only 1-7 days service life, and they are two years old, the net periphery adopts the sewing machine tape edge, this method is made in the process wire netting periphery is damaged, and makes wire netting break easily, yields poorly in process of production, cause cleaned coal to run off, and moisture content increase.
The utility model content
The technical problem that the utility model solves just provides that a kind of fatigue performance is strong, corrosion-resistant, long service life, quantity of cleaned coal height, the fan-shaped net of filter that moisture content is few.
For solving the problems of the technologies described above, the technical scheme that the fan-shaped net of the utility model filter adopts is: the endurance limit that comprises two wire nettings and wire netting periphery, described wire netting and endurance limit are sewed together by first suture, make by second suture in the outside, described two endurance limits, is provided with adhesive linkage along the suture surface on described wire netting and endurance limit.
Its additional technical feature is:
Opposite side surface at described first suture all is provided with adhesive linkage.
The fan-shaped net of filter provided by the utility model compared with prior art has the following advantages: one, owing to comprise the endurance limit of two wire nettings and wire netting periphery, described wire netting and endurance limit are sewed together by first suture, make by second suture in the outside, described two endurance limits, suture surface along described wire netting and endurance limit is provided with adhesive linkage, adhesive linkage adopts elastomeric material to make, adhesive linkage that elastomeric material is made and wire netting and endurance limit baking are together, agitate in the process at wire netting, adhesive linkage is connected as a single entity wire netting and endurance layer, prevented the bending of wire netting and junction, endurance limit, all bending occurs on the endurance limit, prevented to fracture because of bending causes the wire netting edge, reduction of service life, and the adhesive linkage that elastomeric material is made plays certain protective role to first suture, prevented that suture is corroded; Its two owing to all be provided with adhesive linkage, further improved its service life on the first suture opposite side surface, described both sides.
Description of drawings
Fig. 1 is the structural representation of the fan-shaped net of the utility model filter;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the fan-shaped net of the utility model filter.
As depicted in figs. 1 and 2; the structural representation of the fan-shaped net of the utility model filter; the fan-shaped net of this filter comprises two wire nettings 1; outer periphery at every wire netting 1 is made wire netting 1 in 2 inboards, endurance limit by first suture 3; layer of cloth is adopted on endurance limit 2; three limits, 2 outsides, endurance limit are made pocket-like by second suture 4 with wire netting 1 and endurance limit 2; inner surface along first suture 3 on wire netting 1 and endurance limit 2 is provided with adhesive linkage 5; adhesive linkage 5 adopts elastomeric material to make; the adhesive linkage 5 that elastomeric material is made and wire netting 1 and endurance limit 2 bakings are together; agitate in the process at wire netting 1; adhesive linkage 5 is connected as a single entity wire netting 1 and endurance limit 2; prevented the bending of wire netting 1 with 2 junctions, endurance limit; all bending occurs on the endurance limit 2; prevented to fracture because of bending causes the edge of wire netting 1; reduction of service life; and the adhesive linkage that elastomeric material is made plays certain protective role to first suture 3, prevented that first suture 3 is corroded.
In order further to improve its service life, all be provided with adhesive linkage 5 on the opposite side surface of first suture 3.
Protection domain of the present utility model not only is confined to the foregoing description, as long as structure is identical with the fan-shaped nets structure of the utility model filter, just drops on the scope of the utility model protection.
Claims (2)
1. the fan-shaped net of filter, the endurance limit that comprises two wire nettings and wire netting periphery, described wire netting and endurance limit are sewed together by first suture, make by second suture in the outside, described two endurance limits, and it is characterized in that: the suture surface along described wire netting and endurance limit is provided with adhesive linkage.
2. the fan-shaped net of filter according to claim 1 is characterized in that: the opposite side surface at described first suture all is provided with adhesive linkage.
