Description

Seed is sieve piece for screening machine

Technical Field

The utility model relates to the technical field of seed processing, in particular to a sieve sheet for a seed air screening machine.

Background

The shape of the screen holes directly affects the effective area of the screen, which is the ratio of the area occupied by the pure screen holes to the geometric area of the screen surface, and is also called the effective screen surface. The larger the effective area of the sieve is, the larger the number of the sieve holes on the unit sieve surface is, the higher the probability that the material penetrates through the sieve holes is, and therefore, the higher the production capacity and the sieving efficiency are. In screening practice, the shapes of the mesh commonly used are round, square, rectangular, etc. The sieve mesh of the punched sieve surface is mostly circular, and the woven sieve surface is provided with rectangular holes and square holes. Practice proves that the screen surfaces have different screen hole shapes, and the effective screen surface area and the opportunity of mineral grains to penetrate through the screen holes are different. The effective area of the screen is the largest for rectangular screen holes, then square for rectangular screen holes, and the effective area of the circular screen holes is the smallest, so that the productivity per unit area of the screen surface is also reduced in this order. And the sieve pores of the rectangular sieve pores are not easy to block, and the ore particles only need to contact three surfaces or two surfaces of the sieve pores when passing through the sieve pores, so that the resistance is small. But the defects are that strip-shaped, flaky impurities or particles easily penetrate through the sieve pores, so that the product has uneven granularity and insufficient cleanliness.
