technical field

The invention relates to the technical field of a dust removal device and a dust removal process, in particular to a wind wing type rice dust removal device.

Background technique

Rice dedusting is a step that needs to be carried out after finishing the rice. Generally, the common rice dedusting device is a centrifugal dust collector, which consists of an inner cylinder, an outer cylinder, a conical cylinder, an air inlet, and an ash discharge port. The inner and outer cylinders and the ash discharge port are located on the same axis; the inner cylinder is evenly distributed with dust discharge holes that rice grains cannot pass through. Spiral rotating at high speed. During the rotation, the dust particles are thrown to the inner wall of the outer cylinder under the action of a large centrifugal force and collide with the wall surface, friction and the speed gradually decreases to zero, and then fall to the cone part along the cylinder wall under the action of gravity, and then It is discharged from the bottom ash outlet.

At present, the above-mentioned centrifugal dust collectors in the field of rice processing have the following problems. On the one hand, due to the action of centrifugal force, the interaction force between the dust and the outer cylinder wall is relatively large, and the dust is easy to adhere to and accumulate on the outer cylinder wall, which is not easy Cleaning will seriously affect the dust removal effect; on the other hand, the high-speed rotation of the inner and outer cylinders will easily break the rice, resulting in a decline in the overall quality of the rice.

In addition, the steps of dust removal for rice in the past are as follows: 1. Put part of the rice into the inner cylinder; 2. Rotate the inner cylinder to separate the dust from the rice and throw the dust into the wall of the outer cylinder; 3. The dust is discharged from the ash outlet; 4. It is also necessary to discharge the clean rice from the inner cylinder, and then fill in new rice with dust; in the above step 2, when the inner cylinder is rotating, the rice There will be mutual friction between them, which will cause serious wear of the rice and additional dusting; in step 4 above, since there is a large space in the inner cylinder, when the inner cylinder rotates, the inner cylinder will The rice in the inner cylinder cannot be evenly distributed in the inner cylinder, so it is necessary to dedust the rice for a relatively long period of time to achieve a better dust removal effect. After the dust is discharged, the clean rice needs to be discharged, and then Then add rice with dust, so that the inner cylinder cannot continuously remove dust, which affects the work efficiency.

Therefore, the present invention provides a kind of fan type rice dedusting device and technology.
