Problems solved by technology

The sieveless classifier uses air as the dispersion medium to classify the particles in the process of gas flow. The disadvantage is that the separation effect is affected by the fluctuation of the air flow, and the qualified rate of the finished product is difficult to reach 100%.
A sieve classifier uses a sieve to separate particles. Normally, coarse particles are easy to attach to the surface of the sieve, hindering the passage of fine particles, and the classification efficiency is low.

Embodiment Construction

[0010] in the attached picture Among them, the impeller (6) is connected with the motor (1) through the transmission mechanism (4). A motor (1) is installed on the top of the feeding bin (3), and the bottom is fixed on the loam cake (5). The upper part of the coarse powder bin (11) is connected with a cylindrical sieve (7), and the cylindrical sieve (7) is installed on the loam cake (5). A soft connection (12) is provided between the coarse powder bin (11) and the coarse powder bin outlet (9), the fine powder bin (8) is outside the cylindrical sieve (7) and the coarse powder bin (9), and the upper cover (5) be installed on the top of the fine powder bin (8).

[0011] When replacing the cylindrical sieve (7), first the soft connection (12) is opened, and the loam cake (5) and the connection part are lifted, and then the cylindrical sieve (7) can be disassembled.

Abstract

The invention relates to a vacuum classifier, suitable for the field of powder separation. Aiming at the problems that the qualified rate of finished products is very difficult to reach 100% by using a sieve-free classifier and the classification rate is lower because coarse particles are easy to attach on the surface of the sieve by using a sieve classifier, the vacuum classifier disclosed by the invention ensures that qualified particles rapidly enter a fine-powder silo through a cylindrical sieve by using negative pressure air-flow and air-flow generated by high-speed rotation of impellers, and the air-flow generated by high-speed rotation of the impellers enables the particles incapable of passing through the cylindrical sieve to break away from the surface of the cylindrical sieve and drop in a coarse-particle silo. The invention is mainly applied to the industries of pharmacy, food, chemical industry and the like.

Description

technical field [0001] The invention belongs to the field of separation, in particular to a vacuum classifier for powder separation. Background technique [0002] At present, the commonly used powder particle classifiers are mainly divided into two types: classifiers without sieves and classifiers with sieves. The sieveless classifier uses air as the dispersion medium to classify the particles in the process of gas flow. The disadvantage is that the separation effect is affected by the fluctuation of the air flow, and the qualified rate of the finished product is difficult to reach 100%. A sieve classifier uses a sieve to separate particles. Normally, coarse particles are easily attached to the surface of the sieve, hindering the passage of fine particles, and the classification efficiency is low. Contents of the invention [0003] The invention provides a vacuum classifier, the qualified rate of products passing through the vacuum classifier reaches 100%, and the high-sp...
