Abstract
The utility model relates to a step-shaped screen plate which is most suitable for grading raw coal and dewatering coal slurry. The step-shaped screen plate is composed of a step-shaped screen mesh, wherein, the front and the back of the screen mesh are provided with baffle plates, and both side surfaces are provided with side plates. The step-shaped screen mesh is fixed by the side plates and the baffle plates so as to surround into a closed frame. The structure of the step-shaped screen plate is compact and reasonable, and mineral handling capacity including gradation and dewatering can be enhanced. A dewatering effect can be enhanced further for dewatering the coal slurry, and the abrasion of materials to the screen mesh is reduced. Thus, the service life of the screen mesh is increased. The step-shaped screen plate has the advantages of high production efficiency, favorable effect of gradation or dewatering and low production cost, and has wide practicability.
Description
One, technical field
The utility model relates to a kind of stairstepping sieve plate, is particularly useful for carrying out on the bobbing machine classification of mineral or the dehydration of coal slime.
Two, background technology
At present, the sieve plate that is used for stock grading on the bobbing machine and dehydration mostly is plane formula, and bobbing machine sieves or dewaters by the screen cloth that is provided with on the sieve plate in the process of vibration, though existing sieve plate can be finished the classification or the dehydration of material, and satisfy the requirement of producing, but the wearing and tearing of its screen cloth are big, and the life-span is short, maintenance capacity is big, production efficiency is low, and the cost height is unfavorable for further improving the in-depth treating capacity of mineral.
Three, summary of the invention
(1) goal of the invention
In view of the weak point of prior art, the utility model purpose provides a kind of minimizing screen cloth wearing and tearing, improves screen life-span, reduces maintenance, the stairstepping sieve plate of enhancing productivity and reducing production costs.
(2) technical scheme
A kind of stairstepping sieve plate of the utility model, it is made of a stairstepping screen cloth, is provided with baffle plate before and after the screen cloth, and two sides are provided with side plate, the stairstepping screen cloth are fixedly surrounded the frame of a closure by side plate and baffle plate.
A kind of stairstepping sieve plate of the utility model, described stairstepping screen cloth is formed by the bending of flat-surfaced screen set a distance.Flat-surfaced screen can be that processing multiple row set a distance hole is arranged and formed on the sieve plate body, also can be to be arranged by supporting plate and the grating that is fixed together with it to form.Multiple row set a distance hole be arranged as cross arrangement.Arrange the ladder screen cloth that forms by supporting plate and grating, grating can be bent into stairstepping; Also supporting plate can be bent into stairstepping.When being used as Mineral Classification, the flat-surfaced screen bending of mesh forms trapezoidal screen cloth by having at interval, the distance that folding line is certain at interval, and folding line can pass through mesh.Material is under external force during one section pan feeding, through trapezoidal screen cloth.Material less than mesh can see through trapezoidal screen cloth, and discharges from the discharge end of trapezoidal screen cloth under external force greater than the material of mesh.When being used as coal slime dewatering, described trapezoidal screen cloth is made up of supporting plate and the grating that is fixed together with it, grating can be bent into stairstepping; Also supporting plate can be bent into stairstepping.
(3) technique effect
A kind of stairstepping sieve plate of the utility model is best suited for coal classification or coal slime dewatering.Sieve plate with original plane formula, use three-dimensional ladder-type structure instead, compared with prior art, its compact conformation is reasonable, reduced the contact area of mineral and sieve plate, reduced fretting wear, its production efficiency height, classification or dehydrating effect are good, production cost is low, long service life, maintenance capacity is little, has practicality widely.

Accompanying drawing 3 is flat deployable structure figure of Fig. 1 screen cloth.
Accompanying drawing 4 is main TV structure figure of the utility model embodiment two.
Accompanying drawing 5 is A-A topology views of the utility model embodiment two.
Accompanying drawing 6 is main TV structure figure of the utility model embodiment three.
Accompanying drawing 7 is A-A topology views of the utility model embodiment three.
Five, the specific embodiment
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing:
A kind of stairstepping sieve plate of the utility model, it includes trapezoidal screen cloth 1, baffle plate 2 and side plate 3, and side plate 3 is fixed together with baffle plate 2 two ends and surrounds closed frame, and trapezoidal screen cloth 1 just is fixed in the frame.Stairstepping screen cloth 1 is formed by the bending of flat-surfaced screen set a distance, flat-surfaced screen can be that formation is arranged in processing multiple row set a distance hole 4 on the sieve plate body, also can be to arrange by supporting plate 5 and the grating that is fixed together with it 6 to form, multiple row set a distance hole 4 be arranged as cross arrangement, arrange the ladder screen cloth 1 that forms by supporting plate 5 and grating 6, grating 6 can be bent into stairstepping; Also supporting plate 5 can be bent into stairstepping.
When being used as Mineral Classification, the flat-surfaced screen bending of mesh forms trapezoidal screen cloth 1 by having at interval, folding line at intervals, folding line can pass through mesh.Under external force, material is during by an end pan feeding, through trapezoidal screen cloth 1, can see through trapezoidal screen cloth 1 less than the material of mesh, and greater than the material of mesh under the effect of external force, from the discharge end discharge of trapezoidal screen cloth 1.
When being used as coal slime dewatering, trapezoidal screen cloth 1 is made up of supporting plate 5 and the grating 6 that is fixed together with it.Grating 6 can be bent into stairstepping; Also supporting plate 5 can be bent into stairstepping.Under external force, material is during by an end pan feeding, and through trapezoidal screen cloth 1, liquid such as water can see through trapezoidal screen cloth 1, and the less material of moisture is then from the discharge end discharge of trapezoidal screen cloth 1.
