Annular efficient pneumatic separator

Abstract

The invention discloses an annular efficient pneumatic separator. The annular efficient pneumatic separator comprises a horizontally arranged annular air cylinder, wherein an annular grading air duct is formed in the annular air cylinder, an air inlet and an air outlet are formed in the annular air cylinder, at least one material storage bin is arranged below the annular air cylinder, and the annular air cylinder is communicated with the material storage bin through a material grading channel. Compared with the prior art, the annular efficient pneumatic separator has the advantages that structure is simple, implementation is easy, ventilation is enhanced, air is made to be evenly distributed along an annular section, eddy current can be effectively eliminated, wind resistance can be effectively reduced, and energy consumption is reduced; by adjusting air speed, materials with different specific gravities can fall into the corresponding material storage bins in sequence, so that materials in different specifications can be screened at the same time and screening efficiency and screening effect can be effectively improved, and practicality is high.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a ring type high-efficiency wind screener. Background technique [0002] There are two main types of classification for bulk materials: one is to use screening machinery to classify materials, such as various types of vibrating screens. This type of screening machine is easy to cause blockage of the screen holes for wet materials, which makes the classification efficiency of the screening machine The other is wind or hydraulic classification, hydraulic classification belongs to wet classification, and has certain limitations in application. In recent years, with the enhancement of people's environmental awareness, wind classification has gradually shown the characteristics of adapting to the times, and has developed a lot of classification devices. There are two main types: one is the inertial force classification device, which The action of air flow or centrifugal force gen...
