Efficient powder sieving equipment

Abstract

The invention discloses efficient powder sieving equipment which comprises a support, a discharge bin, a sieving box and a sieving box swing system. The sieving box comprises a box body and a sieve, the box body is arranged on the support and capable of reciprocating along a rail mounted on the support, a compressed gas blowback system is arranged below the box body and comprises two polish rods, a gas knife, a servo motor, a first synchronous pulley, a second synchronous pulley and a synchronous belt, the two polish rods are parallelly mounted on the support, the servo motor and the second synchronous pulley are mounted on the support, the first synchronous pulley is mounted on an output shaft of the servo motor, the first synchronous pulley and the second synchronous pulley are connected by the aid of the synchronous belt, the gas knife is positioned below the sieve, mounted between the two polish rods through linear bearings and capable of reciprocating along the polish rods and blowing the sieve, and one end of the gas knife is fixedly connected with the synchronous belt. The efficient powder sieving equipment is simple in structure, reasonable in design, convenient to operate, no easy to block meshes of the sieve, accurate in sieving and high in efficiency.

Description

technical field [0001] The invention relates to a screening device, in particular to a high-efficiency powder screening device. Background technique [0002] Powder is the most common form of solid, and now almost all industrial sectors are involved in the processing of powder. The size and particle size distribution of powder particles have a great influence on the quality of products. Products with different uses and different forms often have different requirements for powder particle size. Mechanical screening and grading is the most common and easiest method. It can intuitively judge the size of powder particles of different particle sizes according to the number of sieve meshes that can pass through. It is also the commonly used powder particle size and particle size distribution in production practice. control method. [0003] Due to the ever-changing shape of the powder particles, and often serious agglomeration, in the production practice process, due to the "arch...
