Abstract
The utility model discloses a ladder-shaped screen plain top type woven screen, which can grade the medium-grain material. The utility model is formed in the method a brake forming treatment is carried out to an isosceles trapezoidal screen in a pre-pressed way, the isosceles trapezoidal screen is woven in a plain top type after the heat treatment. The utility model has the advantages of good screening performance, high screening efficiency, high strength of the screen, good abrasive resistance, long service life, etc. The utility model can be used for the screening machine of various industies.
Description
The utility model belongs to the wear-resisting woven screen of trapezoidal twine flat roof type of fine granularity material used by oscillating screen in the classification.
At present, the vibration screen of fine granularity material in the industry classifications such as metallurgy, coal, building materials, chemical industry, light industry, the general woven screen that all adopts round wire, compound bending, or bend in one direction flat roof type woven screen.Stipulated a kind of flat roof type screen cloth among the international standard ISO 4783-81 " mesh grid of prebuckling forming metal silk ", its twine also is circular.Because the screen cloth mesh cross section of circular twine braiding becomes nearly hyperbola, material very easily forms wedge and blocks mesh, often needs to use the labor cleaning, has seriously restricted the ordinary production efficient of sieving machine.
The purpose of this utility model provides a kind of material that makes and does not hinder the hole, can improve screening efficiency, twine rigidity and friction durability, alleviates the wear-resisting woven screen of trapezoidal twine flat roof type of labor strength.
The utility model is realized by following manner.Adopt isosceles trapezoid twine material, the bottom surface of twine broad makes progress, and unidirectional downward precompressed bending after heat treatment, forms by the flat roof type braiding.The mesh cross section of this screen cloth is trapezoidal.For life-span and the intensity that improves screen cloth, guarantee screen size, the shape as accompanying drawing 1 is processed in the cross section of trapezoidal twine.The bottom surface a of broad should have certain thickness h, and the big I of thickness h is determined according to the purposes of twine specification and screen cloth; Less bottom surface b is processed into circular arc, to increase the intensity of screen cloth.Twine can adopt spring steel or the manufacturing of Stainless Steel material
Below in conjunction with a description of drawings embodiment of the present utility model.
Accompanying drawing 1 is a trapezoidal twine sectional view of the present utility model, and a is the upper bottom surface (being positioned at the top of screen cloth operating position) of broad among the figure; H is the thickness of upper bottom surface; B is less bottom surface, generally is processed into circular arc.
Accompanying drawing 2 is a braiding structure schematic diagram of the present utility model, and 1,2 is the trapezoidal twine of track and column braiding among the figure.
Accompanying drawing 3 is a cutaway view of the present utility model, and c is the distance at adjacent twine center among the figure; R is trapezoidal twine precompressed bending radius; A is the angle of precompressed crooked position.
According to screening raw meal particle size and characteristic, determine trapezoidal twine specification and mesh size.At first the bottom surface a with trapezoidal twine broad makes progress, the pre-downwards V-arrangement shape that extrudes of the distance of the 2C of whenever being separated by on request.The angle of this V-arrangement shape is a, and the bottom cambered surface is R, and both sides are straight.The trapezoidal twine that will bend then intersects in length and breadth, is woven into screen cloth by flat roof type.
It is good that woven screen of the present utility model has a screen-penetrating performance, the screening efficiency height, and screen strength is big, and wearability is good, long service life, the advantage such as versatility, applicability are strong. Can be widely used in the sieving machine of every profession and trade.
