Screening mechanism for flour processing and working method thereof

Abstract

The invention relates to the technical field of flour processing, in particular to a screening mechanism for flour processing and a working method thereof.The screening mechanism comprises a bottom plate, a vibration assembly, a screening box, a box cover and a dust collection assembly.The first filter screen plate and the second filter screen plate are used for vibration screening, large impurities and small particle impurities in wheat can be removed, the impurity removal range is widened, and the screening efficiency is improved. The first filter screen plate and the second filter screen plate are installed by arranging the sliding ways, so that installation of the first filter screen plate and the second filter screen plate is simpler and quicker, convenience is provided for assembly and use of the screening mechanism, meanwhile, the first filter screen plate and the second filter screen plate are also convenient to disassemble, and the screening mechanism is convenient to use. And convenience is provided for cleaning the first filter screen plate and the second filter screen plate, the convenience of maintenance and cleaning of the screening mechanism is improved, and therefore the service life of the screening mechanism is prolonged.

Description

technical field [0001] The invention relates to the technical field of flour processing, in particular to a sieving mechanism for flour processing and a working method thereof. Background technique [0002] Flour is a kind of powder made from wheat. In the process of flour processing, the quality of wheat will directly affect the quality of finished flour. In order to improve the quality of finished flour, it is necessary to strictly control the quality of wheat. Among them, the most The most important thing is to sieve the wheat to remove impurities such as dust, leaves and straw carried in the wheat harvesting and drying process, and to sieve the wheat to remove impurities. At present, a sieving mechanism is usually used. [0003] However, the existing sieving mechanism has great defects in the use process. The existing sieving mechanism uses a vibrating motor, which cannot throw the screened wheat up, and is prone to the risk of network blockage, which affects the screeni...

Problems solved by technology

[0003] However, the existing sieving mechanism has great defects in the use process. The existing sieving mechanism uses a vibrating motor, which cannot throw the screened wheat up, and is prone to the risk of network blockage, which affects the screening efficiency. The screening mechanism has a single-layer screen, and the impurities screened are on the same layer as the wheat, which is difficult to distinguish and affects the screening effect. The screen mesh of the existing screening mechanism is not easy to disassemble and install, which reduces the convenience of use. Cleaning and maintenance shorten the service life. The existing sieving mechanism will scatter a lot of dust during use, which will pollute the surrounding environment and reduce the environmental protection of use.
