Abstract
The utility model relates to the field of screening apparatus in the mineral dressing industry. The aim of the utility model is to provide a wet fine-graded screen sheet for obviously increasing the screen area in the unit plane area of a screen sheet and obviously improving screening efficiency. The screen sheet comprises screen bars and screen holes, the screen bars and the screen holes positioned on the screen bars have shapes similar to waves extended scraggly up and down along the same direction. The wet fine-graded screen sheet is widely applicable to the mineral dressing production industry such as an iron ore mine and so on.
Description
Technical field
The utility model relates to the screening plant field in the ore dressing industry, especially, relates to a kind of wet type fine fraction screening plant.
Background technology
As a kind of screening instrument, wet type fine fraction sieve sheet (having another name called sieve plate) be widely used in industries such as iron ore mine the ore dressing classification, improve field such as concentrate grade.As close-mesh screen sheet, the size of sieving area directly affects ore dressing grade, productive rate, cost and benefit in the unit sieve area of its structure and qualification thus.
As shown in Figure 1, wet type fine fraction sieve sheet of the prior art comprises limit muscle 1, limit muscle 2, dowel 3, grating 4, sieve aperture 5 etc.Wet type fine fraction sieve sheet of the prior art all adopts planar structure, and grating and the sieve aperture of promptly forming the sieve sheet are length strip in the same plane.
At present, adopt wet type fine fraction sieve sheet of the prior art,, only account for about 10% of sieve sheet self area because the restriction of aspects such as raw material and processing technology level makes that effective percent opening of existing horizontal screen sheet is very low.Be subjected to the little limitation of sieving area, a lot of qualified screening materials have little time sieve, just enter the screening system again that circulates again, are ground meticulously by ball mill, be easy to run off, and during energy charge.In a word, wet type fine fraction of the prior art sieve sheet have that sieving area is little, filtration and the loss space is big, the low inferior many defectives of screening efficiency.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of wet type fine fraction sieve sheet, this sieve sheet can obviously increase the sieving area in the unit area of plane, significantly improve screening efficiency, the corresponding raising of material treating capacity in unit interval, bring huge economic interests for the production client, bring immeasurable social benefit also for industry and society.
To achieve these goals, the utility model adopts following technical scheme:
A kind of wet type fine fraction sieve sheet comprises grating and sieve aperture, wherein, and described grating and the sieve aperture between described grating approximate bellows-shaped for extend up and down rough and uneven in surfacely along equidirectional.
Because described grating and sieve aperture are the shape of approximate ripple, therefore, mainly the described wet type fine fraction sieve sheet that is made of described grating and sieve aperture is similarly the approximate bellows-shaped of extending up and down rough and uneven in surfacely.
In other words, the utility model has been broken the consistent traditionally planar structure of wet type fine fraction sieve sheet in the prior art, then adopts the male and female face design.
Owing to adopted said structure, compare with the wet type fine fraction sieve sheet of available technology adopting planar structure, the utility model has solved existing problem of available technology adopting horizontal screen sheet and defective effectively, with the same area of plane of original sieve sheet in increased the length of each sieve aperture, and then enlarged whole effective sifting area, and because of the difference of the concrete structure of male and female face, the sieving area of increase is at least greater than not waiting more than 30%.Correspondingly, the corresponding raising of material treating capacity in the unit interval brings huge economic interests for the production client, brings immeasurable social benefit also for industry and society.
For the ease of understanding the utility model, the technical solution of the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The specific embodiment
As shown in Figure 2, wet type fine fraction sieve sheet described in the utility model comprises limit muscle 10, limit muscle 20, dowel 30, grating 40 and sieve aperture 50.Wherein, described grating 40 and the approximate bellows-shaped of the sieve aperture between described grating 40 50 for extend up and down rough and uneven in surfacely along equidirectional.Because described wet type fine fraction sieve sheet mainly is made of grating 40 and sieve aperture 50, therefore, described wet type fine fraction sieve sheet is similarly the approximate bellows-shaped of extending up and down rough and uneven in surfacely.
As long as the shape of described grating 40 can be designed to the various possible approximate bellows-shaped that can play the increase sieving area according to the specific requirement of material thickness and mining industry production.Preferably, can adopt following different shape:
As shown in Figure 4, the crest of the approximate ripple of described grating and trough are angular shape.
As shown in Figure 5, the crest of the approximate ripple of described grating is an angular shape, and trough is for falling trapezoidal shape.
As shown in Figure 6, the crest of the approximate ripple of described grating is the trapezoid shape, and trough is an angular shape.
As shown in Figure 7, the crest of the approximate ripple of described grating is the trapezoid shape, and trough is for falling trapezoidal shape.
As shown in Figure 8, the crest of the approximate ripple of described grating and trough are square shape, and wherein, the width of trough bottom can be greater than the width at crest top.
Embodiment 6
As shown in Figure 9, the approximate ripple of described grating is sine or cosine shape.
Embodiment 7
As shown in figure 10, the crest of the approximate ripple of described grating is the crest shape of sine or cosine, and trough is the platform shape.
Embodiment 8
As shown in figure 11, the crest of the approximate ripple of described grating is the platform shape, and trough is the crest shape of sine or cosine.
The utility model adopts the male and female face design, broken the consistent traditionally planar structure of wet type fine fraction sieve sheet in the prior art, with the same sieve plate plane area of original sieve sheet in increased the length of each sieve aperture, and then enlarged whole effective sifting area, and because of the difference (such as above-mentioned different embodiment) of the concrete structure of male and female face, the sieving area of increase is at least greater than not waiting more than 30%.
In addition, material all was to rely on plane gravity cutting technique classification in the past, can adopt the comprehensive gravity cutting technique of plane, inclined-plane even vertical plane classification (alleged cutting technique refers to material and the friction of sieve aperture edge intercepts) now here, for the utility model, not only can improve the sieve aperture precision, and effective sifting area and screening efficiency all can be increased to 50%-100%.
As mentioned above, embodiment of the present utility model has been described, but the utility model is not limited to the foregoing description, does not break away from the utility model of being put down in writing in the claim scope, can carry out multiple design and change.
