Problems solved by technology

[0003] The traditional rice screening mechanism is simple in structure, and vibrating screening is performed through a vibrating plate screen. Although the screening efficiency is high, it needs to be shut down to clean the vibrating screen or replace the vibrating screen. The production is not continuous, the efficiency is not high, and some debris remains Mixed with rice grains, the separation efficiency of waste residue and rice grains is not high, and the screening effect is not good

Embodiment 1

[0022] see Figure 1~3 , in an embodiment of the present invention, a rice processing and screening device includes a box body 1, a primary screening mechanism and a secondary screening mechanism; On both sides of the box body 1, the left end of the screen drum 2 is connected with a feeding hopper 3, and the rice to be screened is put into the feeding hopper 3; the screen drum 2 is provided with a central shaft 5, and the central shaft 5 is fixedly connected to the first helical blade. Group 5, the first helical blade group 5 pushes the rice to move to the right, the part of the screen cylinder 2 located in the box 1 is evenly distributed with screen holes 4, and the rice passes through the screen holes 4 and enters the box body 1; the screen cylinder 2 pairs The waste residue is intercepted and continues to push the waste residue to move to the right. The right end of the screen cylinder 2 is nested with a conical cover 8. The conical cover 8 is a hollow conical cylinder with...

Embodiment 2

[0025] see Figure 4 The difference between this embodiment and Embodiment 1 is that: the lower end of the first material guide plate 11 is fixedly connected with a blower 21, and the blower 11 is connected to a blower 23 through an air pipe 22, and the blower 23 is fixed to the outer wall of the box body 1. Connected, the box 1 is located on the inner wall of the blowing head 11 and is provided with an ash discharge tank 24. The ash discharge tank 24 is arranged obliquely to prevent rice grains from entering the ash discharge tank 24; the ash discharge tank 24 is connected with an ash collection cover 25 , The dust collection cover 25 communicates with the cyclone settling cylinder 26 through the pipeline to settle the dust.

Abstract

The invention discloses a rice processing screening device. The rice processing screening device comprises a tank, a primary screening mechanism and a secondary screening mechanism. The primary screening mechanism comprises a screen drum. The left end of the screen drum communicates with a feed hopper. A conical cover is nested in the right end of the screen drum. The secondary screening mechanismis arranged in the tank. The secondary screening mechanism comprises a screen net. A grating plate is arranged above the screen net. The rice processing screening device conducts high-efficiency preliminary screening on a rice material through the screen drum provided with a first spiral blade set, conducts high-efficiency separation on waste residues through the conical cover and a second spiralblade set to improve the screening effect, conducts secondary screening on the rice material and separates residues through the arc-shaped screen net and the grating plate to improve the screening effect and conducts separation and collection on dust particles in the rice material through an air blower, a blowing head, a dust collection cover and a cyclone sedimentation cylinder to ensure the screening effect.

Description

technical field [0001] The invention relates to the field of rice processing machinery, in particular to a rice processing and screening device. Background technique [0002] The process of removing the husk (chaff) and cortex (bran layer) of rice. Rice grains are composed of chaff, cortex, germ and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the minimum degree of crushing, and make rice with better eating quality. The above-mentioned processed rice needs to be sieved before it can be marketed. [0003] The traditional rice screening mechanism is simple in structure, and vibrating screening is performed through a vibrating plate screen. Although the screening efficiency is high, it needs to be shut down to clean the vibrating screen or replace the vibrating screen. The production is not continuous, the efficiency is not high, and some debris remains Mixed with rice grains, the separation efficiency of waste residue and rice ...
