Problems solved by technology
The commonly used sieve plate is made of ordinary steel plate through the process of punching square holes. The disadvantage of this kind of sieve plate is that the overall elasticity of the sieve plate is poor, which is not conducive to screening. Second, the wear resistance of the sieve hole is poor. , the service life is short, if high wear resistance materials or surface strengthening process are used, although the wear resistance performance can be improved, the cost is high, and at the same time, the elasticity of the sieve plate cannot be improved

Embodiment Construction
[0005] The present invention will be described in detail in conjunction with the above-mentioned drawings. Vertical and horizontal sieve plate ribs 2 are evenly distributed in the sieve plate frame 1, and square sieve holes 3 are evenly distributed in the box surrounded by the vertical and horizontal sieve plate sieves. The above-mentioned longitudinal and transverse sieve plate ribs are fixedly connected to the sieve plate frame by a single or multi-strand steel wire rope, and the sieve hole 3 is formed by polyurethane, and the size of the hole is determined according to the standard. The forming method of this sieve plate is that the vertical and horizontal sieve plate bars are evenly distributed in the polyurethane vulcanization forming mold, and the mold is provided with protrusions forming the sieve holes 3, and the vertical and horizontal sieve plate bars made of steel wire ropes are pressed in the vulcanization mold. Wrapped in a polyurethane sieve. In order to prevent ...

The invention discloses a screen plate of high-precision multi-step granularity test screen, belonging to the technical field of solid separation, for providing a screen plate of high-precision multi-step granularity test screen, with better anti-wear property and elasticity. The technical scheme of the invention comprises a screen plate made from polyurethane, wherein the screen plate comprises single-strand or multi-strand steel wire screen plate ribs uniformly distributed longitudinally and laterally, two ends of the ribs are connected with a screen plate frame, the square frame of the longitudinal and lateral screen plate ribs is provided with square meshes, the upper portion of each mesh is straight while the lower portion is horn hole. The invention can be used for metallurgy screening granularity test.
Description
Technical field: [0001] The invention relates to a solid separation technology, in particular to a sieve plate of a high-precision multi-step particle size inspection sieve. Background technique: [0002] As a sieve plate used to test the filtration accuracy test sieve, its requirements are higher than ordinary sieve plates. The commonly used sieve plate is made of ordinary steel plate through the process of punching square holes. The disadvantage of this kind of sieve plate is that the overall elasticity of the sieve plate is poor, which is not conducive to screening. Second, the wear resistance of the sieve hole is poor. , the service life is short, if high wear resistance material or surface strengthening process is adopted, although the wear resistance performance can be improved, the cost is high, and at the same time, the elasticity of the sieve plate cannot be improved. Invention content: [0003] The object of the present invention is to provide a sieve plate of a...
