Powder sieve with controllable mesh number

Abstract

The invention discloses a powder sieve with controllable mesh number. The powder sieve comprises a closed casing provided with a feed inlet, a discharge outlet, at least three sorting ports and three screens. The feed inlet and the 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. The sorting ports of the casing are disposed on the bottom surface of the casing, and the 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 a powder separation device, in particular to a powder mesh controllable 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, or the ordinary sieve is used to manually shake the sieved material, which is inaccurately controlled and inconvenient to use, and the production environment of the plant is poor, and the powder is easy to be crushed. The worker breathes into the lungs, which affects the health of the worker. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic ...
