Feeding-controllable system for screening before flour grinding of wheat

Abstract

The controllable feeding screening system before wheat flour milling includes a bracket and a feeding tube. The upper part of the bracket is horizontally equipped with an upper frame, and the upper frame is equipped with a storage tank. The lower end of the storage tank is connected with a diversion tube. Rotationally connected to the supporting hanging structure, the lower end of the guide pipe is inserted into the feeding pipe, the feeding pipe is composed of a straight pipe section arranged vertically on the upper part and a curved pipe section at the lower part, and a swing driving mechanism connected with the straight pipe section is arranged on the bracket ;The lower part of the support is provided with a lower frame, the lower frame is provided with a vibrating screen, and the bent pipe section is provided with a feeding and iron chip suction device for adjusting the size of the lower port of the feeding pipe; the support is provided with a device for removing large particles of impurities on the vibrating screen And an impurity cleaning mechanism that collects iron filings and impurities. The invention integrates the removal of magnetic impurities and large particle impurities, and has the beneficial effects of high degree of automation, easy operation, good screening effect and high screening efficiency.

Description

technical field [0001] The invention belongs to the technical field of material screening, and in particular relates to a controllable unloading type wheat flour pre-milling screening system. Background technique [0002] The process of processing wheat into flour has to go through multiple steps, two of which are very important steps to remove the large grain impurities and magnetic impurities mixed in the wheat, the existing impurity removal process is also divided into two steps, and adopts Two different sets of equipment, the traditional wheat magnetic impurities removal device has a complex structure, and the treatment is not clean enough, and the efficiency is low; the traditional equipment for screening large particles of impurities also has uneven paving of the wheat entering the screen, and the screening effect Poor, low screening efficiency defects. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention prov...
