Description

Bran removing device Technical Field The utility model relates to the field of flour industry, in particular to the field of cleaning of impurities in raw grains, and particularly relates to a bran removing device. Background In the flour processing industry, the removal of impurities from wheat is a critical step to ensure the quality of the final product. The impurities mainly comprise wheat bran, wheat straw and lime soil, wherein the wheat bran accounts for about half of the total amount of the impurities. The traditional impurity removing equipment mainly adopts a vertical air suction channel technology, but the method has obvious defects and shortcomings. The vertical air suction duct has low impurity removal efficiency, and is mainly characterized in the following aspects: 1. the wind direction of the air suction duct is vertical upwards, which requires that the gravity of the wheat bran must be overcome when the wheat bran is separated. In the separation process, as wheat continuously falls down, part of wheat bran can be smashed back by the fallen wheat, so that the cleaning is not thorough. 2. The energy consumption is high, and because the gravity separation of wheat bran needs to be overcome, the energy consumption is increased, and the cleaning effect is poor. 3. For high-flow materials, the material layer is too thick, so that wind pressure cannot penetrate through the material layer, wheat grains are easily sucked out due to the too large wind pressure, and wheat bran cannot be effectively separated due to the too small wind pressure. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides the bran removing device which has high efficiency, simple structure and wider application range. In order to achieve the above object, the bran removing device of the present utility model is as follows: This remove bran device, its key feature is, the device include except that bran main part, refining board, air intake, air inlet pipeline and air outlet, the refining board set up at the top of removing the bran main part, the air intake be located the lateral wall of removing the bran main part, link to each other through the buckle with remove the bran main part, the side of removing the bran main part be equipped with a horn mouth, the air outlet also be the port that the bran mouth is located the horn mouth simultaneously, be horn mouth design, the horn mouth lower extreme have the slope. Preferably, the device further comprises an observation window, and the observation window is arranged on the horn mouth of the bran removing main body. Preferably, the air inlet comprises four detachable shutters, two groups of two shutters are arranged, one shutter in each group is transversely arranged, the other shutter is longitudinally arranged on the transverse shutter, and the wind shields of all shutters are horizontal. Preferably, the device further comprises a wheat feed inlet and a wheat discharge outlet, wherein the wheat feed inlet is positioned at the top of the bran removing main body, the wheat discharge outlet is positioned at the bottom of the bran removing main body, and the wheat discharge outlet and the horn mouth form a funnel structure.
