Background
At present, the smelting of ferrovanadium by using a large-scale tilting furnace electro-aluminothermic process at home and abroad only climbs one division of steel Xichang steel vanadium products, and the ferrovanadium is screened by adopting a round hole type vibrating screen plate in the crushing process at present. Because the ferrovanadium crushing adopts the process flow of 'two-stage jaw crushing plus vibrating screen screening', the screening uses a round hole type sieve plate, the material blockage is serious, the screening effect is poor, and round holes are easy to wear and grow in the crushing and screening process, so that the ferrovanadium crushing time is long, the fine powder rate is high, the product granularity is gradually increased, the production efficiency is lower, the production cost is higher, and the like. The existing ferrovanadium crushing and screening vibrating screen adopts a circular hole screen plate, and the material blockage of the vibrating screen is very serious in the production process, so that the crushing time of the ferrovanadium in a single furnace is longer, the production efficiency is greatly reduced, and the energy consumption cost is greatly increased. The ferrovanadium crushing system is designed to be only provided with a first-stage vibrating screen, ferrovanadium enters the vibrating screen for screening after being coarsely crushed, screened substances enter the vibrating screen for screening together with the coarsely crushed ferrovanadium after being secondarily crushed, and due to the fact that the vibrating screen is low in porosity and serious in blocking, part of ferrovanadium is caused to continuously circulate between the vibrating screen and the secondary crusher, the ferrovanadium fine powder rate is high, the finished product fine powder rate is 16.9% at present, the finished product rate is low, and the production cost is high. Because the circular hole sieve is serious in material blockage and difficult to clean, sieve pores are larger and larger in size in the production process, and large ferrovanadium is easy to appear in a product, so that the quality of the product is increased. The above problems also occur when the round hole type vibrating screen plate is used for screening other types of ores.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a shale shaker sieve for ore crushing separation for solve the putty that the ore screening in-process appears serious, the screening effect is relatively poor scheduling problem, improve screening efficiency.
For solving the technical problem, the utility model discloses the technical scheme who adopts does:
a shale shaker sieve for ore crushing separation has seted up a plurality of through-holes on the sieve, the through-hole part or whole are trapezoidal through-hole, and the tip of this trapezoidal through-hole is towards the feed side, and the tip is towards the ejection of compact side. Trapezoidal through-hole structure for the ore is difficult to the card in the through-hole when the screening, can not take place the putty, and hole wearing and tearing greatly reduced is showing and is improving screening efficiency.
As a further improvement of the scheme, the through holes on the sieve plate are arranged in rows and are sequentially arranged along the feeding direction, and the through holes in 2 adjacent rows are aligned or staggered. The through holes can be aligned or staggered according to the requirement.
As a further improvement of the above scheme, the sieve plate is formed by sequentially connecting a plurality of strip-shaped plates along the feeding direction, the length direction of the strip-shaped plates is vertical to the feeding direction, and one side of the strip-shaped plate body is provided with a plurality of trapezoidal bulges; between 2 adjacent strip-shaped plates, the body of one strip-shaped plate is connected with the trapezoidal bulge of another strip-shaped plate. The structural style of the strip-shaped plates can avoid the phenomenon of material blockage, and the screening efficiency is improved.
As a further improvement of the above aspect, the trapezoidal bulge is located the discharge side of the strip body, the small end of the trapezoidal bulge faces the discharge side, and between 2 adjacent strips, the trapezoidal bulge of the strip close to the feed side is connected above the body of the strip close to the discharge side. The stepped sieve plate structure is beneficial to the rolling of ores, and the occurrence of material blockage can be further avoided.
As a further improvement of the above scheme, the trapezoidal bulge is located the feeding side of the strip-shaped plate body, the big end of the trapezoidal bulge faces the feeding side, and between 2 adjacent strip-shaped plates, the trapezoidal bulge of the strip-shaped plate close to the discharging side is connected below the body of the strip-shaped plate close to the feeding side. The sieve plate structure with the reverse step shape has better sieving effect on certain special ores.
As a further improvement of the above solution, the trapezoidal through hole is an isosceles trapezoid through hole. The isosceles trapezoid through holes are the optimal through hole structure and have the best screening effect.

Detailed Description
The following detailed description of the present invention will be provided in order to further understand the concept of the present invention, the technical problems, the technical features constituting the technical solutions, and the technical effects brought by the technical features of the present invention, which are described in the following with reference to the accompanying drawings. However, the description of the embodiments is illustrative and not intended to limit the present invention.
The utility model discloses an improve screening efficiency, designed the sieve of a brand-new structure, evenly seted up a plurality of trapezoidal through-holes on this sieve, the microcephaly end of trapezoidal through-hole is towards the feed side, and the major part end is towards the ejection of compact side. Such through-hole structure for the ore is difficult to the card in the through-hole when the screening, can not take place the putty, and hole wearing and tearing greatly reduced is showing and is improving screening efficiency.
Trapezoidal through-holes on the sieve are arranged in rows, multiple rows of through-holes are sequentially arranged along the feeding direction, and the adjacent 2 rows of trapezoidal through-holes can be aligned or staggered according to actual needs.
The sieve plate can be made by directly punching a single metal plate into trapezoidal through holes, and also can be formed by sequentially welding a plurality of metal strip plates along the feeding direction, the length direction of each strip plate is perpendicular to the feeding direction, and one side of each strip plate body is provided with a plurality of trapezoidal convex parts which are the same in shape, the same in arrangement mode and are uniformly arranged at intervals. Between 2 adjacent strip-shaped plates, the body of one strip-shaped plate is welded with the trapezoidal bulge of the other strip-shaped plate. Obviously, the sieve plate formed by welding a plurality of metal strip plates has better sieving effect than the sieve plate formed by punching a trapezoidal through hole on a single metal plate, and is less prone to material blockage.
The sieve plate formed by welding a plurality of metal strip plates has the following 2 types of arrangement modes of trapezoidal bulges:
the first embodiment is as follows: this trapezoidal bulge is located the ejection of compact side of strip shaped plate body, and the microcephaly end of trapezoidal bulge is towards the ejection of compact side, and between 2 adjacent strip shaped plates, is close to the trapezoidal bulge of the strip shaped plate of feeding side and welds in the top of the body of the strip shaped plate that is close to the ejection of compact side.
