Rice husk cleaning, warehousing and conveying production line

Abstract

A rice husk cleaning, warehousing and conveying production line comprises a cleaning classification work section, a storage work section and a wind power conveying work section, all of which are sequentially arranged. The cleaning classification work section comprises a double-screw feeder, a first elevator, a permanent magnetic drum, a double-barrel rotation screen and a light impurity gatheringscrew conveyor. The storage work section comprises a second elevator, a both-way screw conveyor, a bin feeding scraper conveyor, a pneumatic gate valve, a rice husk bin, a bin bottom screw conveyor and a bin discharging scraper conveyor. The wind power conveying work section comprises positive-pressure conveying equipment or negative-pressure conveying equipment, and a feeding port of the positive-pressure conveying equipment or negative-pressure conveying equipment is connected with a discharging port of the bin discharging scraper conveyor. The rice husk cleaning, warehousing and conveying production line is complete in function, and the three major functions of rice husk cleaning, storing and wind power conveying can be finished. The rice husk cleaning, warehousing and conveying production line can be used for comprehensive rice husk cleaning, moulding is avoided in the storage process, bridging / arching of rice husks in the bin is not likely to happen, bin discharging is more reliable, positive-pressure and negative-pressure wind power conveying is adopted according to the conveying distance, stability and reliability are achieved, and energy saving and environment friendlinessare achieved.

Description

technical field

[0001] The invention belongs to the technical field of agricultural and sideline products processing, and in particular relates to a chaff cleaning, storage and conveying production line. Background technique

[0002] Rice husk, also known as rice husk, is the outer layer of rice husk, which is the largest by-product in the process of rice processing. Chaff has good toughness, porosity, low density (112--144 Kg / m 3 ) and rough texture. Due to the porosity of chaff, the large specific surface area is easy to absorb a large amount of dust, and it is not easy to clean. For a long time, as an auxiliary material in the brewing process, a large number of chaff with unstable impurity content and large content has been used, which affects the quality of wine products and is not conducive to the promotion of mechanization and automation of equipment in the brewing industry; chaff is rough in texture and strong in toughness. The biggest problem in warehousing is mat...
