Description

A kind of punching sieve

Technical field

This utility model relates to the sieve of powder screening, especially relates to be applied to feed manufacturing, food processing, ore deposit Powder such as is selected materials at a kind of punching sieve in powder screening processing.

Background technology

Select materials etc. in powder screening processing at feed manufacturing, food processing, breeze, produce to filter granular material Product, are widely used screen cloth and carry out the screening of material and select materials.The size of the screen-aperture on screen cloth determines its sieved powder The largest particles diameter of body, and the number of sieve number determines in the unit interval by the amounts of particles of screen cloth, here " the mesh number " of indication is exactly hole count, the screen number that i.e. screen cloth is gone up per square inch.Existing screen cloth is because designing, adding Work is unreasonable, causes mesh number under equal aperture less, and screening production efficiency of selecting materials is relatively low, and the granule produced is big The little uniformity is poor.

Utility model content

The technical problems to be solved in the utility model is: the problem existed for prior art, it is provided that a kind of punching sieve, Improve the production efficiency selected materials of screening, and the granule after making screening select materials is more uniform.

The technical problems to be solved in the utility model realizes by the following technical solutions: a kind of punching sieve, including base Plate, offers several sieve apertures on substrate, and several sieve apertures described are the sieve apertures of equivalent specifications, and branch on substrate Arrangement, is being parallel to each other and between two adjacent row sieve apertures, by laying respectively at upper and lower two row and the most adjacent 3 sieves Line between the geometric center in hole is collectively forming an equilateral triangle.

Preferably, described sieve aperture be aperture be the manhole of 0.6mm, and sieve number is 48 mesh.

Preferably, described sieve aperture be aperture be the manhole of 0.7mm, and sieve number is 44 mesh.

Preferably, described sieve aperture be aperture be the manhole of 0.8mm, and sieve number is 40 mesh.

Preferably, described sieve aperture be aperture be the manhole of 0.9mm.

Preferably, the sieve number of described sieve is 35 mesh.

Preferably, described substrate uses steel plate to process.

Preferably, described substrate uses Q235 steel plate to process.

Preferably, described substrate uses corrosion resistant plate to process.

Preferably, described substrate uses aluminium alloy plate to process.

Compared with prior art, the beneficial effects of the utility model are: several sieves being arranged on substrate due to branch Hole is the sieve aperture of equivalent specifications, and is being parallel to each other and between two adjacent row sieve apertures, by lay respectively at upper and lower two row and Line between the geometric center of 3 the most adjacent sieve apertures together form an equilateral triangle, therefore, this reality Can be implemented under equal aperture by novel punching sieve, improve sieve number, thus utilize this punching sieve to enter The size that row sieves produced granule of selecting materials is more uniform, and the screening Particle production in the unit interval is bigger, has Improve the production efficiency that screening is selected materials to effect.

Accompanying drawing explanation

Fig. 1 is the structural map of this utility model a kind of punching sieve.

In figure, component token name claims: 1-substrate, 2-sieve aperture, 3-first line of centres, 4-second line of centres, 5- Three lines of centres.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and specifically This utility model is described in detail by embodiment.Should be appreciated that specific embodiment described herein is only in order to solve Release this utility model, be not used to limit this utility model.

Punching sieve as shown in Figure 1, including substrate 1, offers the sieve aperture 2 of several circles on substrate 1, described Several sieve apertures 2 be the sieve aperture of equivalent specifications, and branch's arrangement on substrate 1, be positioned at same walk crosswise several Sieve aperture 2 equidistantly arranges, and the line between its geometric center is second line of centres 4, is positioned at and is tilted to the left 60 degree Several sieve apertures 2 in same diagonal equidistantly arrange, and the line between its geometric center is the 3rd line of centres 5, Being positioned at several sieve apertures 2 being tilted to the right in the same diagonal of 60 degree is also equidistantly arrangement, between its geometric center Line is first line of centres 3, is being parallel to each other and between two adjacent row sieve apertures 2, by laying respectively at upper and lower two row And the line between the geometric center of 3 the most adjacent sieve apertures 2, i.e. first line of centres 3, second line of centres 4, 3rd line of centres 5, together form an equilateral triangle.

Screening in order to utilize above-mentioned punching sieve to carry out different diameter airborne particle material is selected materials, if being positioned on substrate 1 A dry sieve aperture 2 can be provided that

The manhole that described sieve aperture 2 uses aperture to be 0.6mm, and, the sieve number of described punching sieve is 48 mesh.

The manhole that described sieve aperture 2 uses aperture to be 0.7mm, and, the sieve number of described punching sieve is 44 mesh.

The manhole that described sieve aperture 2 uses aperture to be 0.8mm, and, the sieve number of described punching sieve is 40 mesh.

The manhole that described sieve aperture 2 uses aperture to be 0.9mm, and, the sieve number of described punching sieve is 35 mesh.

After punching sieve of the present utility model uses said structure design, it is possible to achieve under equal aperture so that its Sieve number is improved, and therefore, utilizes punching sieve of the present utility model to carry out screening when selecting materials, is produced The size of granule materials is more uniform, and, the yield of the sieving granular material in the unit interval is bigger, thus The production efficiency that screening is selected materials can be effectively improved.

Punching sieve of the present utility model, can be to use steel plate to process, it is also possible to be to use corrosion resistant plate processing Form, or use aluminium alloy plate to process.Described substrate 1, can be further at warm after punching molding Reason forms punching sieve, to improve the service life of punching sieve.After punching sieve molding, it is possible to use vernier calliper The aperture of sieve aperture 2 measured by chi, and calculates hole count interior per square inch, it would however also be possible to employ path clearance gauge checks sieve aperture 2 Aperture.Especially, when described substrate 1 uses Q235 steel plate to process, not only raw material sources are extensive, favorably Production cost in punching sieve controls, and is additionally, since its phosphorus content moderate, and comprehensive mechanical performance is preferable, and machinery is strong The performances such as degree, plasticity and welding are preferably coordinated, so that punching sieve is more easily processed, and ensure that it uses Reliably.It addition, described sieve aperture 2 can also be not limited to manhole as shown in Figure 1, according to different screening things The different demands of material, described sieve aperture 2 can also is that rhombus through hole, square through hole, or regular polygon through hole, Such as regular hexagon through hole, octagon through hole etc..

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, it should refer to Go out, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all Within protection domain of the present utility model should be included in.
