Abstract

The invention relates to the technical field of flour screening devices, in particular to a positive and negative pressure repetitive flour fine screening device, comprising a box body and a power mechanism, wherein a vertically arranged screening box is arranged in the box body, and the screen The sub-box is rotatably connected with the box body, and the screening box includes a feeding part for conveying flour to its interior, a discharging part for discharging miscellaneous materials, and two oppositely arranged screening surfaces. There is a filter hole for filtering flour. The power mechanism drives the sieving box to swing left and right in the box. By swinging the sieving box, the sieving surface reciprocates and hits the box close to the sieving surface. inner wall. The device utilizes the movement of the sieving box to generate the effect of gas flow, which not only reduces the probability of clogging of the filter holes, but also achieves a rapid sieving effect.

Description

technical field [0001] The invention relates to the technical field of flour screening devices, in particular to a positive and negative pressure repetitive flour fine screening device. Background technique [0002] When flour is processed, a very important step is to remove impurities from the flour. In the prior art, the impurities in the flour whose particles are larger than the flour are removed by a screening device, and the blocking of the screen during the screening process has always been a problem to be solved urgently for the flour screening machine. . SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the shortcoming that the sieve holes for sieving flour in the prior art are easily blocked, and propose a positive and negative pressure repeated type flour fine sieving device. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A positive and negative pressure re...
