Multi-level dust removal rice screening device

Abstract

The invention discloses a rice screening device with multi-stage dust removal. The feeding port of the screening box is connected to the feeding hopper through a pipeline. The dust pipe is connected to the dust collection box; the screening area includes an agitator and a screening plate, the screening plate is located below the agitator, and the agitator includes a stirring shaft with an impeller; the screening plate is provided with a coarse screening area, a medium screening area and a fine screening area in turn , and the corresponding collection chambers are set directly below; the bottom surface of each collection chamber is provided with a discharge port; the second dust suction hood in the side dust removal area is connected to the water tank through the second dust suction pipe. The present invention is equipped with two-stage dust removal, which has good dust removal effect, can not only ensure the working environment but also improve the cleanliness of rice; its screening structure is ingenious, and dust can be collected while screening in the screening box, so that the working environment is good; the structure design is reasonable, and once It can distinguish rice grains of different sizes without going through multi-layer screens, and the discharge is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of rice screening equipment, in particular to a rice screening and dust removal device with multi-stage dust removal. Background technique [0002] The size of the rice grains in the stacked rice is inconsistent. When packing, it is necessary to distinguish rice grains of different sizes for different packaging; the existing rice screening is to screen the upper and lower multi-layer screens in sequence, and there is no setting Vacuuming often causes the rice husks in the rice to raise dust into the atmosphere, or cause a large amount of dust to scatter into the air, affecting the working environment. [0003] In order to overcome the above-mentioned defects, those skilled in the art actively conduct innovative researches, in order to create a rice screening device with multi-stage dust removal. SUMMARY OF THE INVENTION [0004] Aiming at the problems existing in the prior art, the present invention provi...
