Screening device for rice processing and production

Abstract

The invention provides a screening device for rice processing and production. The screening device comprises a stainless steel coarse-mesh screening net plate, a vibration motor, a damping spring, a supporting sleeve and a rubber damping pad, wherein the stainless steel coarse-mesh screening net plate is mounted on the upper side of the interior of a screening box body; and the vibration motor isassembled in the middle of the lower end face of the screening box body. Through the design, the problems that an original screening device does not have the multi-stage screening capacity, and rice is prone to being accumulated in the screening process are solved; the supporting sleeve is attached to the annular side face of a limiting plate; the rubber damping pad is bonded to the lower end faceof a fixed bottom plate; the damping spring is clamped on the lower side of the interior of the supporting sleeve; and through the design, the problems that the original screening device does not have the damping and buffering capacity, and noise is large in the using process are solved. Compared with the prior art, the screening device is reasonable in structure, has the vibration screening capacity and the damping capacity, and is high in screening efficiency, low in working noise, simple in structure and high in reliability.

Description

technical field [0001] The invention relates to a screening device for rice processing and production, which belongs to the technical field of rice processing equipment. Background technique [0002] Rice is made by rolling rice, and rice bran is mixed in rice. In addition to rice bran being a by-product of rice rolling, the broken grains produced by rice rolling will also affect the quality of rice. In order not to affect people's consumption, use The quality of rice is better, and it is necessary to separate and screen rice bran, broken grains and plump rice. The traditional screening method is to pour the rice containing rice bran and broken grains directly into the sieve, and then manually screen. This method not only has low screening efficiency, but also is not suitable for large-scale rice processing and production, which affects the needs of rapid production; and now Some screening devices generally use the exhaust fan to generate wind to blow up light impurities su...

Problems solved by technology

The traditional screening method is to pour the rice containing rice bran and broken grains directly into the sieve, and then manually screen. This method not only has low screening efficiency, but also is not suitable for large-scale rice processing and production, which affects the needs of rapid production; and now Some screening devices generally use the exhaust fan to generate wind to blow up light impurities such as rice bran and separate them from the rice. However, the screening sieve itself cannot be moved, and often the rice piled on the sieve will cause the mesh of the sieve to be blocked. It is difficult for the wind to blow the rice bran and lighter grains pressed by the rice, which leads to poor screening effect of rice, and the blown rice bran cannot be collected well, and it is troublesome to clean after screening. It may stick to the surface of rice, and now there is an urgent need for a screening device for rice processing and production to solve the above problems
