A rice polishing residue processing and dedusting device

Abstract

The invention provides dust removal device for rice polishing residue treatment. The dust removal device comprises a rice polishing machine, a polishing residue treatment and dust removal machine, a secondary dust removal treatment machine, a waste dust residue treatment chamber, air conditioning plate groups and an operation console. A worker starts the rice polishing machine through the operation console, and the polishing residue treatment and dust removal machine discharges polishing powder generated in the polishing process into a first polishing powder sedimentation treatment bin for sedimentation. Waste dust and part of polishing powder in a pipeline are subjected to secondary dust removal treatment by the secondary dust removal treatment machine, the internal waste dust enters thewaste dust residue treatment chamber for treatment, the part of polishing powder is treated and enters a second polishing powder sedimentation treatment bin for sedimentation, and the internal air volume of a connecting pipeline is adjusted through the air adjusting plate groups to ensure the balance of the overall air volume, so that the polishing residue treatment and dust removal machine and the secondary dust removal treatment machine treat the polishing powder and the waste dust to a maximum extent, the polishing quality of rice is improved, and the pollution of the waste dust residue tooutdoor air is reduced.

Description

technical field [0001] The invention relates to a rice polishing treatment device, in particular to a rice polishing residue treatment and dust removal device, which belongs to the technical field of agricultural product processing. Background technique [0002] During the production and processing of rice, it usually goes through the following processes: raw grain cleaning (drum initial cleaning, vibrating sieve, de-stoner), ridge paddy (hulling by paddy huller), separation of paddy mixture, separation of brown rice Unripe grains, rice milling, separation and screening, color sorting, polishing, white rice grading, and finished product packaging. During the rice polishing process, the bran powder on the rice surface is removed by the rice polishing machine, and the resulting polishing powder enters the brake dragon through the air duct for sedimentation and dust removal. [0003] During the polishing residue treatment process of existing rice, the bran powder on the rice s...

AI Technical Summary

Problems solved by technology

In the process of rice polishing residue treatment, there is no water spray device inside the warehouse connected to the bottom of the straight-through air locker. After the polishing powder enters the interior of the warehouse, it cannot be quickly settled, resulting in high gas pressure at the warehouse mouth. , causing a pressure burden on the pipeline, affecting the settlement of the polishing powder, and in the waste dust treatment process, the usually used direct outdoor working method affects the air environment and affects the waste dust on the environment

[0004] On the whole, the existing technology mainly has the following defects: one is that during the process of sedimentation of the polishing powder, there is no water spraying device inside the bin body, and it is not easy to carry out the sedimentation treatment work after the polishing powder enters the bin body, so that the gas pressure at the bin body mouth Larger, it will cause a pressure burden on the pipeline at the entrance of the warehouse, affect the settlement of the polishing powder, and easily damage the polishing machine, and the long-term work of the device under high pressure has certain dangers; the second is that during the waste dust treatment process, the waste dust The working method of directly discharging outdoors will cause certain pollution to the environment, resulting in excessive dust, which is not conducive to environmental protection and damages human health. The efficiency is low, the settlement effect is poor, and the expected effect cannot be achieved
