Abstract
The invention discloses a multistage drum sieve. The multistage drum sieve comprises 1-6 sieves with the sieve pore pitch increasing successively, wherein each sieve is of a single arrangement structure; ribs for supporting are arranged on the inner wall of a reel drum between each two sieves; the ribs are provided with annular openings; the openings of each two adjacent ribs are staggered by at least one opening moment; the height of the ribs can be determined according to the overall fraction of supplied materials; and the space between each two adjacent ribs is equal. The multistage drum sieve is simple in structure, safe, reliable and convenient to use; and besides, the sieving and discrete level efficiency is effectively improved, energy consumption and the depreciation consumption of frequency conversion equipment are reduced on sieving time efficiency, the production cost is greatly reduced, and the economic efficiency is improved.
Description
[technical field]
The present invention relates to the plant equipment field, relate in particular to a kind of multistage cylinder.
[background technology]
Multistage drum sieve commonly used at present wets or the wet classification screening for the dried of ore dressing or upright level sampling for metallurgical industry, can access two or more products, and its advantage is that work is more steady, and its shortcoming is that screening efficiency is low.Material enters the multistage drum sieve that tilts to put the dress rotation from the oversize entrance, and screen cloth 1 is that the sieve aperture pitch-row increases successively to the mesh structure characteristics of screen cloth 6, gets the sample of size fractionated with sieve.Material at first passes through screen cloth 1, because screen cloth is the cylindrical shape of rotation, so material only is about the 1/6-1/8 of whole screen cloth 1 area through out-of-date sieving area, material has certain thickness at compass screen surface in screening process, also has phenomenons such as material impacting vibration, and compass screen surface is along the limited length of material trend, the original material flow that should be sized through screen cloth 1 of part just is sized through screen cloth 2, even the screen cloth 3 of flowing through is sized, until screen cloth 6, by that analogy.Cause sieving unclear, sampling is inaccurate.
The technical scheme that solves similar problem both at home and abroad has:
(1) frequency conversion drive rotational circle shaft screen, de-spin in the hope of prolonging the time of staying of oversize on compass screen surface, increases effective screening time in equal effective screen cloth length.
(2) reduce the drum sieve angle of inclination, slow down the go forward one by one speed of oversize on the drum sieve compass screen surface, in the hope of prolonging the time of staying of oversize on compass screen surface, increase effective screening time in equal effective screen cloth length.
More than two kinds of measures all can effectively improve the upright stage efficiency of screening to a certain extent, but increased the depreciation consumption of energy consumption and frequency conversion equipment in the screening time efficiency.
[summary of the invention]
At the shortcoming of prior art, the object of the present invention is to provide a kind of multistage drum sieve simple in structure, safe and reliable, easy to use.
The technical solution used in the present invention is: a kind of multistage drum sieve, comprise 1 to 6 screen cloth that the sieve aperture pitch-row increases successively, it is characterized in that: each screen cloth is respectively the single assembling structure of putting, put at the inwall of screen frame cylinder between each screen cloth and rib is housed supports, described rib is circular opening, the opening of the adjacent rib more than one opening square that misplaces.
Further, described rib can be determined height according to the comprehensive grade of supplied materials.
Further, the spacing of described rib equates.
Beneficial effect of the present invention is: the upright stage efficiency of raising simple in structure, safe and reliable, easy to use, effective screening, reduced the depreciation consumption of energy consumption and frequency conversion equipment in the screening time efficiency, and greatly reduce production cost, improved business efficiency.

[specific embodiment]
Referring to accompanying drawing, a kind of multistage drum sieve of the present invention, comprise 1 to 6 screen cloth that the sieve aperture pitch-row increases successively, it is characterized in that: each screen cloth is respectively the single assembling structure of putting, put at the inwall of screen frame cylinder between each screen cloth and rib is housed supports, described rib is circular opening, the opening of the adjacent rib more than one opening square that misplaces.
Screen cloth 1 is respectively the single assembling structure of putting to screen cloth 6, put at the inwall of screen frame cylinder to the interval between the screen cloth 6 with screen cloth 1 and to adorn a plurality of circular opening " rib " and support, the opening rib has certain height (specifically determining with the comprehensive grade of supplied materials), the spacing of ring frame equates, constitute an intercaste between per two ring frames, the opening corresponding relation of each ring frame, more than one opening distance successively misplaces.When rotation, material enters screen cloth 2 via screen cloth 1 screening back by rib 1 opening, because the characteristics of direction of rotation, supplied materials is intercepted by rib 2, rotates materials flow along the reverse side of rib opening, treat that drum sieve rotates a circle after, oversize flows into screen cloth 3 by the opening part of rib 2 again, by that analogy.Above course of action can guarantee that the oversize material all can sieve a week less than an opening distance on each grade screen cloth, and both opening equaled 1/8 of rib circular arc length apart from arc length, and material is about 7/8 of whole screen area through out-of-date sieving area so.1/6-1/8 compared with original technology is greatly improved.
See attached list 1, effectively raise the efficient of screening sampling after implementing, provide strong technical support to the analysis of sampled data.Contrast prior art and present technique, both the screenings to prior art screen cloth 1 sieved again, can also sift out 2% of total amount at screen cloth 1 position, illustrated that this material of 2% is not flowed into the later screen cloth intercaste of screen cloth 2 by screen cloth 1 well sifted in a screening process.Implement after the improvement technology, same carries out regrading with an outsifting, the conclusion that draws is can also sift out 0.5% of total amount at screen cloth 1 position, and efficient obviously improves, and this outsifting of 0.5% also comprises grade collision cracked the cause amount of screen cloth 2-6 in rotation process in screening process.
At this preferred embodiment that this invention has been described, comprise that the inventor is used to implement known optimal mode of the present invention.The change of preferred embodiment is apparent for those of ordinary skills after reading above-mentioned explanation.The inventor wishes the change that the those of ordinary skill rational Application is such, and the inventor thinks and offers some clarification on different application at this and also can realize the present invention.Therefore, the present invention includes all modifications and the equivalents of the purport of quoting in the claim of enclosing, this allows in the law that is suitable for.In addition, any combination of all possible change of above-mentioned key element is also comprised by the present invention, unless point out in addition or obvious contradiction in context at this.
