Description

A circulating air selector for flour production

Technical Field

The utility model belongs to the technical field of grain machinery, in particular to a circulating air selector for flour production.

Background Art

Wheat is the raw material for flour production. Before flour production, wheat will be mixed with a small amount of impurities such as dust, fine straw and bran. Therefore, in order not to affect the production and quality of flour, the wheat needs to be cleaned. With the rapid development of science and technology, the impurity removal work no longer needs to be done manually, but is done through air separators.

Existing document CN219378000U-A flour production circulating air selector comprises a box body and a dust box, one side of the dust box is fixedly connected to one side of the box body, a partition plate is fixedly connected to the interior of the box body, a cross-flow fan is fixedly connected to the top of the partition plate, the other side of the cross-flow fan is fixedly connected to the interior of the box body, a motor is fixedly connected to one side of the box body, the output end of the motor is fixedly connected to one side of the cross-flow fan, a screening plate is fixedly connected to one side of the partition plate, dust is blocked by the dust filter plate, the dust filter plate is knocked by the second shaking cylinder to vibrate it, and dust is helped to fall into the dust box, so as to prevent dust from accumulating at the dust filter plate and affecting the circulation of airflow, and dust is collected by a cleaning bucket, and the cleaning bucket is pulled out through a pull-out port to clean the collected dust, but it still has the following disadvantages in actual use:

1. The above-mentioned flour production circulating air selector screens wheat through the screening plate, and the screened impurities pass through the screening plate and fall into the box body. The impurities are moved to the dust collecting box through the cross-flow fan, but the farther away from the cross-flow fan, the smaller the suction force. Therefore, the impurities on the side of the screening plate away from the cross-flow fan are prone to accumulation, resulting in insufficient collection of impurities.

2. The above-mentioned flour production circulating air selector uses the second shaking cylinder to knock the dust filter plate to make it vibrate, thereby helping the dust fall into the interior of the dust collecting box. However, when the second shaking cylinder causes the dust to fall into the interior of the dust collecting box, it will also cause the dust to fall into the box body, thereby reducing its collection efficiency.
