Screening device for processing grain ultrafine powder

Abstract

The invention relates to the technical field of grain ultrafine powder screening, and discloses a screening device for grain ultrafine powder processing, which comprises a base and a screening box, the base is connected with a hanging bracket positioned at the top through two vertical support frames, and a telescopic hose A for feeding is communicated between the top of the screening box and the hanging bracket; the screening box is movably arranged between the hanging bracket and the supporting frame, a penetrating fine powder filter screen is arranged at the bottom of the screening box, a powder guiding cover fixed to the bottom wall of the fine powder filter screen is connected to the lower portion of the fine powder filter screen in a covering mode, a discharging port of the powder guiding cover is communicated with a material collecting box fixed to the top of the base, and an exhaust fan with a filter screen at an air inlet is arranged on the right side wall of the material collecting box. A motor is fixed to the left supporting frame and pushes a connecting plate connected with the bottom of the screening and filtering box through two movable rods. The problems that when fine powder is accumulated, the density is large, rapid discharging is difficult, the screening difficulty is large, and large particles and impurities can block screen holes, and work is seriously affected are solved.

Description

technical field [0001] The invention relates to the technical field of grain ultrafine powder screening, in particular to a screening device for grain ultrafine powder processing. Background technique [0002] The nutritional value of grains is high, and they are usually processed into fine powders and combined with other ingredients to make food or drinks. During the process of making superfine grains from grains, there will be larger grain particles, which may also be mixed with impurities. Therefore, it is necessary to Screening of impurities and larger particles. [0003] At present, there are few types of screening machines for ultra-fine powder in the market. The common disadvantage is that the fine powder is too fine, and the density is high when stacked, so it is difficult to quickly discharge the material. The diameter of the screen hole itself is relatively small. If the size is small, this will lead to great difficulty in screening, and larger particles and impur...
