Abstract
The utility model provides a flange disc type net rack. The flange disc type net rack comprises an upper flange disc and a lower flange disc which are mutually matched, wherein the upper flange disc and the lower flange disc are in a ring-shaped structure respectively and are respectively provided with bolt holes which are matched mutually; the opposite surfaces of the upper flange disc and the lower flange disc are respectively provided with a convex groove and a concave groove which are mutually matched; the height of the convex groove and the depth of the concave groove are 3mm-10mm respectively. The flange disc type net rack provided by the utility model has the technical effects that the meshing force is enough for guaranteeing the tensioning force on the flange disc net rack, and due to meshing of the concave groove and the convex groove, a sieve is also prevented from dropping on the net rack; when a sieve mesh is replaced, bolts for fixing the upper flange disc and the lower flange disc only need to be disassembled, so that the fast and convenient effects are achieved.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of flange plate type rack that is applied on the vibratory sieve.
Background technology
At present, vibratory sieve is circular mostly, and is used for the rack of fixed grit on the vibratory sieve, mainly contains two kinds of gluing screen cloth and S shape racks.Gluing rack is to utilize the glue stickiness that the screen cloth of tightening is fixed on Stainless-steel space grids, although be conducive to guarantee the rate of tension of screen cloth, is conducive to material screening, complex process during the daily replacing of screen cloth, and Production Time is very long, and cost is higher.S type rack then is that two stainless steel wires are directly embraced screen cloth and realized fixingly, although be beneficial to the replacing of screen cloth, because the rate of tension of screen cloth is inadequate, gets loose easily, usually can cause adverse effect to screening effect.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide the flange plate type rack, so that when guaranteeing intensity of sieve-mesh, be convenient to the dismounting and change of screen cloth.
The utility model is achieved through the following technical solutions:
The flange plate type rack comprises upper flange plate and the lower flange of working in coordination; Be circulus on upper flange plate and the lower flange; Be equipped with the bolt hole of working in coordination on described upper flange plate and the lower flange; The tongue of working in coordination and the groove that are respectively equipped with on the opposite face of described upper flange plate and lower flange; The height of described tongue and the degree of depth of groove are 3mm～10mm.
Above-mentioned flange plate type rack, described tongue are loop configuration, and the center overlaps with upper flange plate or the lower flange at its place, and described groove is the circulus for matching with tongue also.
The beneficial effects of the utility model are:
Two fixing realizations of flange plate bolt cooperate convenient disassembly up and down; On the flange surface that cooperates the cooperation tongue and groove is set, effectively guarantees the Zhang Jindu of screen cloth.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model provides the flange plate type rack, comprises upper flange plate 1 and the lower flange 2 of working in coordination.
Such as Fig. 1, Fig. 2 and shown in Figure 3, upper flange plate 1 is circulus, and screen cloth covers the middle macropore of circulus during use.Upper flange plate 1 edge is provided with the bolt hole 3 that cooperates with lower flange 2; Upper flange plate 1 and lower flange 2 relative one sides are provided with tongue 4; Tongue 4 in the form of a ring, the center of ring-type overlaps with the ring center of upper flange plate 1; The height of described tongue 4 is 3mm～10mm.
Such as Fig. 4, Fig. 5 and shown in Figure 6, be circulus on the lower flange 2, screen cloth covers the middle macropore of circulus during use.Lower flange 2 is provided with the bolt hole 3 that cooperates with upper flange plate 1; Lower flange 2 and upper flange plate 1 relative one side is provided with and above-mentioned tongue 4 fit 5; Groove 5 is the ring-type of size and tongue 4 couplings, and the center of groove 5 ring-types overlaps with the ring center of lower flange 2; The degree of depth of groove 5 is identical with the height of tongue 4.
As shown in Figure 7 and Figure 8, upper flange plate 1 is welded in stainless steel upper ledge 6 bottoms of vibratory equipment, lower flange 2 is welded on stainless steel underframe 7 tops of vibratory equipment, during assembling, screen cloth is positioned between upper flange plate 1 and the lower flange 2, adjust upper flange plate 1 and lower flange 2 after the tensioning, tongue 4 is aimed at groove 5, meanwhile, upper flange plate 1 is also aimed at the bolt hole 3 between the lower flange 2, bolt 8 passes bolt hole 3 locking upper flange plate 1 and lower flanges 2, and tongue 4 is engaged with groove 5, and snap-in force makes sieve screen tightening and fixing.
Snap-in force is enough to guarantee the tensile force of screen cloth on the ring flange rack, and the interlock of groove and tongue prevents that also sieve from coming off from rack; When changing screen cloth, pull down the fixing up and down bolt of two ring flanges namely replaceable, efficient and convenient.
As the alternative of present embodiment, also tongue can be arranged at upper flange plate and groove is arranged at lower flange.
Above-described embodiment only is for illustrating that clearly the utility model creates example, and is not the restriction of the utility model being created the specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description, need not also can't give all embodiments exhaustive here.And the apparent variation of being amplified out thus or change still are among the protection domain of the utility model creation claim.
