Automatic powder demagnetization equipment

Abstract

The invention provides automatic powder demagnetization equipment. According to the automatic powder demagnetization equipment, a spiral buffer mechanism is arranged, and therefore the material falling speed is reduced, the particle collision time is prolonged, meanwhile, in the process that particles are changed from movable to static, a tangential-velocity component is achieved, completely inelastic collision is avoided, shearing crushing of powder particles is effectively prevented, tiny particles such as dust attached to the surfaces of the powder particles can be separated, materials areprevented from falling on a screen net and prevented from being accumulated, and the screening effect is good; a screening mechanism is arranged, and therefore accumulation of a large amount of powderon the screen net can be avoided, the grading efficiency is high, overall machine vibration is avoided, and the service life is prolonged; a demagnetization mechanism is arranged, and therefore the demagnetization effect is good, demagnetization is carried out while screening is carried out, screening is carried out while demagnetization is carried out, the number of process steps is smaller, theworking efficiency is high, and economic returns are good; and the structure is simple, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the field of medical processing devices, in particular to an automatic demagnetization device for medicinal powder. Background technique [0002] At present, in the processing of medicinal materials, the powder produced by the grinder will be mixed with many large particles. Generally, it is necessary to screen the first-milled medicinal powder. Many existing manufacturers still use sieves for manual screening, which wastes a lot of labor. And the screening speed It is very slow, which greatly affects the production efficiency, and the use of mechanical screening is the use of screening machines. Ordinary screening machines do not meet the requirements of the medicinal material production environment. [0003] In the prior art, due to the difference in material particle size and material shape, the material is easy to block the sieve plate during screening, resulting in a large amount of material accumulation on the sieve plate...

Problems solved by technology

[0002] At present, in the processing of medicinal materials, the powder produced by the grinder will be mixed with many large particles. Generally, it is necessary to screen the first-milled medicinal powder. Many existing manufacturers still use sieves for manual screening, which wastes a lot of labor. And the screening speed It is very slow, which greatly affects the production efficiency, and the use of mechanical screening is the use of screening machines. Ordinary screening machines do not meet the requirements of the medicinal material production environment.

[0003] In the prior art, due to the difference in material particle size and material shape, the material is easy to block the sieve plate during screening, resulting in a large amount of material accumulation on the sieve plate. The existing double-layer sieve plate Difficult to solve this problem, seriously affecting production efficiency

[0004] At present, it is known that the processing of pharm...
