Powder sieve with automatic controlled mesh number

Abstract

The invention discloses a powder sieve with automatic controlled mesh number. The powder sieve comprises a closed casing fixed to a vibrating support, and a feed inlet and a discharge outlet are respectively arranged on two opposite sides of the casing and located on the same straight line. The bottom surface of the casing tilts downwards from the feed inlet to the discharge outlet. At least three sorting ports of the casing are disposed on the bottom surface of the casing, and three screens are arranged at the tops of the sorting ports, are respectively superposed on the bottom surface of the casing and are respectively fastened in a chute at the bottom of the casing. The sorting ports are arranged on the bottom surface of the casing side by side. Powder raise in plants can be avoided during sieving, so that a good environment is provided for workers. Besides, the powder sieve provided with an automatic sieving device is simple in structure, low in cost and convenient to use. As the bottom surface of the casing is arranged obliquely, powder can be sieved automatically from the feeding process to the sorting process.

Description

technical field [0001] The invention relates to an automatic powder material separation device, in particular to a powder material mesh automatic control sieve. Background technique [0002] Powder is an important raw material in chemical production. Generally, whether the particle size of the intermediate product powder meets the requirements will directly affect the quality of the produced product. However, in the existing production, no attention has been paid to the uniform powder Particle size, usually the intermediate product is directly put into use after being pulverized by a mining mill. Due to the lack of automatic control, ordinary screens are used to shake the material manually, which is inaccurate in control, inconvenient to use, and the production environment of the plant is poor. The powder is easily breathed into the lungs by the workers, which will affect the health of the workers. Contents of the invention [0003] The technical problem to be solved by t...
