Description

Technical Field

[0001] The invention relates to the technical field of rice dust removal equipment, in particular to rice production dust removal equipment. Background Art

[0002] Rice production dust removal equipment is specialized equipment used to remove dust and impurities during rice processing. It effectively improves rice cleanliness and ensures product quality. This type of equipment typically includes vibrating screens, suction separators, and cyclone dust collectors. These devices use different physical principles to separate and remove dust and light impurities from rice. When designing and selecting rice production dust removal equipment, factors such as processing capacity, dust removal efficiency, energy consumption, and ease of operation and maintenance must be considered to meet the needs of rice processing plants of varying sizes.

[0003] The existing rice dust removal equipment has low dust removal efficiency and poor dust removal quality, and is prone to dust residue, which affects product quality. Based on these problems, Chinese patent CN214052580U discloses a rice production dust removal equipment, which drives two worm wheels to rotate counterclockwise through a worm, and the two worm wheels drive two circular rods to make counterclockwise circular motion based on the corresponding connecting shaft as the axis. The two circular rods push the two vertical plates downward by contacting with the corresponding cross bars and compress the support springs. The two vertical plates jointly drive the screen downward. After the connecting shaft rotates a certain angle, the circular rods are out of contact with the cross bars, and the two vertical plates are between the two support springs. The rice is then pulled back to its original position and the rice is then pulled back to its original position, which in turn causes the rice to move out of the way and out of the way of the collecting box.

[0004] During the process of removing dust from rice, the dust removal device is not a fully enclosed structure. Therefore, after dust is generated, it will float out of the dust removal device. The dust floating in the air will cause harm to the health of the workers. The dust floating out of the dust removal device will fall downward due to gravity, so some of the dust will fall back into the discharge box and re-attach to the rice. Summary of the Invention
