Rice-bran separator

Abstract

The invention relates to a rice-bran separator which comprises a base, a vibration screening mechanism, a vibration mechanism, a feeding cabin, a feeding funnel and an air separation dust collection system, wherein the vibration mechanism is fixed on the base; the vibration screening mechanism is arranged on one side of the vibration mechanism and is connected with the driving end of the vibration mechanism; the bottom of the vibration screening mechanism is hinged with the base through a plurality of connecting rods; a feeding hole is formed in the upper end of the vibration screening mechanism; a discharge hole is formed in the lower end of the vibration screening mechanism; the feeding cabin is arranged above the feeding hole; the bottom of the feeding cabin is communicated with the feeding hole; the feeding funnel is arranged above the feeding cabin; the bottom of the feeding funnel is communicated with the top of the feeding cabin; and the air selection dust collection system is arranged at the connecting part of the bottom of the feeding funnel and the top of the feeding cabin. The rice-bran separator has the advantages that the structure is simple, bran, dust and impurities can be effectively separated through two screening procedures of air separation and vibration screening, the efficiency is relatively high, problems that dust is adhered to a screening surface and normal use can be affected are avoided, the maintenance overhaul frequency of a machine is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a grain separating device, in particular to a rice and rough separator. Background technique [0002] At present, in the process of rice processing, there are a lot of impurities such as rice bran and dust after being hulled by the hulling machine. At this time, the rice and bran must be separated by a paddy separator. [0003] The traditional paddy separator only adopts a single vibration screening, dust and other impurities in the material are easy to adhere to the screen surface, which affects the normal use and increases the cost and frequency of maintenance and repair in the later period, and in the case of more rice bran In this situation, the screening effect is not ideal, and the screening efficiency is extremely low. High-quality rice must be processed many times, which virtually increases the cost of production and processing.

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a rice and rough separator, which effectively solves the problem that dust and other impurities in the material are easily attached to the screen surface during vibratory screening of the prior art rice and rough separator, which greatly affects the Normal use increases the cost and frequency of later maintenance and repairs. In addition, it also solves the problem that the screening effect is not ideal when there is a lot of rice bran, and the screening efficiency is extremely low. High-quality rice must be processed many times. Defects that increase the cost of production and processing
