Air purifying device

Abstract

The invention discloses an air purifying device used for a flour processing plant. The air purifying device comprises a shell, a filtering device, an air extracting device, a fine mist purifying device and a sterilizing and disinfecting device, wherein the filtering device, the air extracting device, the fine mist purifying device and the sterilizing and disinfecting device are sequentially installed in the shell. The filtering device comprises a rough filtering layer and a fine filtering layer. A limiting protruding groove for fixing the rough filtering layer and the fine filtering layer is formed in the inner surface of the shell. A sliding groove is formed in the position, at the positions of the rough filtering layer and the fine filtering layer, of the shell. The sliding groove is further provided with a sliding block. The end, penetrating a sliding plate, of the sliding block is fixedly connected with a cleaning brush. Limiting fixing grooves are formed in the two ends of the sliding groove. First fixing threaded holes are formed in the sliding plate and the shell, and the sliding plate and the shell are fixedly installed together through a first sealing ring. A first impurity outlet is formed in the bottom of the shell, and a first closed round piece is hinged to the first impurity outlet. A second sealing ring is arranged on the edge of the first closed round piece, anda sealing protruding groove is formed in the first impurity outlet. The first closed round piece is further connected with a protruding edge.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device for flour processing plants, in particular to an air purification device for flour processing plants based on the principle of ultrafine mist particle adsorption. Background technique [0002] Flour is a powder made from wheat and is one of the most common food ingredients. According to the protein content in flour, it can be divided into high-gluten flour, low-gluten flour and gluten-free flour. Flour that has been stored for a longer period of time is better in quality than freshly ground flour. There is a folk saying that "wheat eats old, rice eats new"; flour and rice are best eaten together. The more flour that is ground closer to the center of the flour grain, the higher the grade, and the lower the grade as the amount of flour that is ground near the outer skin of the flour increases. The grade of flour is also directly related to the ...
