Abstract
The utility model relates to a polyurethane rubber sieve plate which is composed of transverse ribs and longitudinal ribs. The utility model is characterized in that the longitudinal ribs are convex ribs higher than the transverse ribs on the plane of a sieve net, and a longitudinal flow groove is formed between two adjacent longitudinal ribs. When in use, the sieve plate is arranged into an oblique angle of 18 DEG-25 DEG by the book. The materials flow along the longitudinal flow grooves along with the vibration of the sieve plate, and the large materials fall down along the convex ribs without directly impacting the transverse ribs of the sieve plate and blocking holes. Besides, the utility model can raise the sieve passing rate of the small materials. The utility model has the advantages of long service life, favorable sieve passing performance and low noise.
Description
Technical field
The utility model relates to sieve plate, more specifically says so to be mainly used in the mine sieve plate that big material such as ore are screened.
Background technology
In the ore dressing of mine factory, include non-ferrous metal, Summoning and nonmetallic ore, large-scale aggregate gradations of newly building a power station etc. all will use the large aperture sieve.The large aperture sieve that generally uses at present all is a flat-surfaced screen, just constitutes all net muscle of sieve plate grid, comprises that horizontal rib and lengthways of rod all are to exist together in one plane.In the use, big material ore is sharp because of shape irregularity, corner, and is very serious to the damage of sieve plate, influenced the normal service life of sieve plate greatly.Material plug-hole phenomenon is also very frequent, and enterprise's production cost is strengthened, and labor strength and maintenance load are all very big.In the use, sieve breakage can bring product defective, easily something unexpected happened.
Summary of the invention
The utility model is the polyurethane rubber sieve plate for avoiding above-mentioned existing in prior technology weak point, provide a kind of to increase the service life, reduce the plug-hole phenomenon, improving product percent of pass.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model is made of horizontal rib and lengthways of rod, its design feature be described lengthways of rod be on screen plane above the convex tendon of horizontal rib, form vertical chute between adjacent two lengthways of rod.
Design feature of the present utility model also is described in horizontal rib and/or lengthways of rod, built-in enhancing steel skeleton or enhancing steel wire rope.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is set to convex tendon by lengthways of rod, forms vertical chute of material between adjacent two lengthways of rod.During use, along with the vibration of sieve plate, material is moving along the longitudinal stream concentrated flow in motion process, big material descends along convex tendon, can directly not impact the horizontal rib of sieve plate, thereby can not cause too early damage to sieve plate, plug-hole not, screen-penetrating performance can height, sieve plate long service life, noise are low.
2, the utility model can use in multiple ore-dressing practices such as nonferrous metals ore, Summoning ore deposit, water power building materials, and is in extensive range.
3, the utility model is in light weight, is convenient to install.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Number in the figure: 1 horizontal rib, 2 lengthways of rod, 3 vertical chutes, 4 press strips.
The specific embodiment:
Referring to accompanying drawing, present embodiment is made of horizontal rib 1 and lengthways of rod 2.
Shown in the figure, lengthways of rod 2 be on screen plane above the convex tendon of horizontal rib 1, form vertical chute 3 between adjacent two lengthways of rod 2.
In concrete the enforcement, at polyurethane material, design by mould, adopt cast and mould pressing process,, set the size of mesh size according to different instructions for uses, and the height of convex tendon and width, so that form vertical chute of material, in horizontal rib 1 and/or lengthways of rod 2, built-in enhancing steel skeleton or enhancing steel wire rope.
For the ease of transportation with install, and in order to adapt to the requirements of different sizes, sieve plate can adopt the modular construction shown in the figure, about implement assembly unit between two modules, press solidly by press strip 4.This version does not need to use lifting gear when mounted.
During use, sieve plate is set to 18 °-25 ° angle of inclination routinely, and along with the vibration of sieve plate, material is moving along the longitudinal stream concentrated flow, and big material descends along convex tendon, can directly not impact the horizontal rib of sieve plate, plug-hole not, and can improve the screening percentage of little material.
