Stirring type sieving screen

Abstract

The invention relates to a stirring type sieving screen. The sieving screen comprises a first screen body and a second screen body, wherein the first screen body and the second screen body are arranged side by side and can be polarized; the first screen body comprises a first base and a first screen disc which is arranged on the first base and is provided with at least three overlapped screens; the second screen body comprises a second base and a second screen disc which is arranged on the second base and is provided with at least two overlapped screens; a discharge port of the first upper-layer screen of the first screen disc communicates with the second upper-layer screen of the second screen disc; a feeding device is arranged on the first upper-layer screen; and mounting racks are arranged above the first screen disc and the second screen disc, stirring motors which are coaxial with the first screen disc and the second screen disc are arranged on the mounting racks, and output shafts of the stirring motors are connected with stirrers which extend into the first upper-layer screen and the second upper-layer screen and are used for stirring seed materials. By means of the stirringmode, the stirring type sieving screen has the advantages that the more seed materials are screened at the same time, the screening speed is high, the effect is good, and the screening efficiency ofthe sieving screen is greatly improved.

Description

technical field [0001] The invention relates to the field of screening equipment, in particular to a stirring type submesh sieve. Background technique [0002] The sub-mesh sieve is used to screen out the granular products in different levels to obtain the products with the required particle size. A product and industry that requires screening and grading. The sub-mesh sieve is divided into a linear vibrating sub-mesh sieve and a circular sub-mesh sieve, and the circular sub-mesh sieve is usually used in the field of food processing, such as the sub-mesh sieving of pepper seeds. [0003] The existing circular sub-mesh sieve usually uses polarization to vibrate the sieve plate, and sieves the smaller particles downward layer by layer. However, this sieving method has certain requirements on the feeding speed, and a small amount of feeding is required to To achieve the purpose of full screening, once the amount of feed increases, the seed material is easy to accumulate in th...

Problems solved by technology

[0003] The existing circular sub-mesh sieve usually uses polarization to vibrate the sieve plate, and sieves the smaller particles downward layer by layer. However, this sieving method has certain requirements on the feeding speed, and a small amount of feeding is required to To achieve the purpose of sufficient screening, once the amount of feed increases, the seed material is easy to cause accumulation in the vibrating sieve tray or even block the sieve holes, requiring more vibration time to sieve well, which greatly reduces the screening efficiency of the sub-mesh sieve
