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
The invention belongs to separation field, in particular for the vacuum fractionation device of powder separation.
Background technology
At present, powder granule clasfficiator commonly used mainly is divided into two kinds: no sieve classifier and sieve classifier is arranged.No sieve classifier utilizes air as decentralized medium, and particle is carried out classification in the gas flow process, and its shortcoming is that separating effect receives the airflow fluctuation influence, and product qualified rate is difficult to reach absolutely.Have sieve classifier to utilize the screen cloth separating particles, generally, coarse granule is attached to screen surface easily, hinders fine grained and passes through, and classification efficiency is lower.
Summary of the invention
The present invention provides a kind of vacuum fractionation device, and the qualification rate of the product through this vacuum fractionation device reaches 100%, utilizes high velocity air to prevent that coarse granule is attached to screen surface, and classification efficiency is high.
The technical scheme that the present invention adopted is: the vacuum fractionation device is made up of motor, transmission mechanism, impeller, feeding warehouse, tubular sieve, meal storehouse, fine powder storehouse; Motor, transmission mechanism, impeller connect from top to bottom successively; Feeding warehouse, tubular sieve, meal storehouse are communicated with from top to bottom successively; It is inner that impeller is positioned at the tubular sieve, and the fine powder storehouse is outside at tubular sieve and meal storehouse.Fine powder warehouse discharging mouth is connected with corollary equipment collecting bin, blower fan.
During work, the air-flow that contains particle gets into feeding warehouse by charging aperture, successively through discharging behind impeller, tubular sieve, fine powder storehouse, collecting bin, the blower fan.Utilize negative-pressure air-flow and impeller to rotate the air-flow of generation at a high speed, make qualified particle fast through the tubular sieve, get into the fine powder storehouse, the air-flow that impeller rotates generation at a high speed makes the particle that can not pass through the tubular sieve break away from tubular sieve surface simultaneously, falls into the meal storehouse.
The tubular sieve is changeable type, can select the tubular sieve in different apertures according to demand.
The qualification rate that the invention has the beneficial effects as follows the product through the vacuum fractionation device reaches 100%, and vacuum fractionation device screen surface is adhered materials not, and production capacity is big, and energy consumption is low.The present invention is mainly used in industries such as pharmacy, food, chemical industry.
Description of drawings
Accompanying drawing is the sketch map of vacuum fractionation device embodiment.
1. motors among the figure, 2. charging aperture, 3. feeding warehouse, 4. transmission mechanism, 5. loam cake, 6. impeller, 7. tubular sieve, 8. fine powder storehouse, 9. meal warehouse discharging mouth, 10. fine powder warehouse discharging mouth, 11. meal storehouses, 12. are flexible coupling.
The specific embodiment
In the accompanying drawings, impeller (6) links to each other with motor (1) through transmission mechanism (4).Motor (1) is installed on feeding warehouse (3) top, and the bottom is fixed on the loam cake (5).Top, meal storehouse (11) connects tubular sieve (7), and tubular sieve (7) is installed on the loam cake (5).Be provided be flexible coupling (12) between meal storehouse (11) and the meal warehouse discharging mouth (9), fine powder storehouse (8) in tubular sieve (7) and outside, meal storehouse (9), loam cake (5) is installed in top, fine powder storehouse (8).
When changing tubular sieve (7), open will be flexible coupling earlier (12), loam cake (5) and coupling part is risen, i.e. detachable tubular sieve (7).
Claims (2)
1. vacuum fractionation device; Form by motor, transmission mechanism, impeller, feeding warehouse, tubular sieve, meal storehouse, fine powder storehouse; It is characterized in that: utilize negative-pressure air-flow and impeller to rotate the air-flow of generation at a high speed, make qualified particle, get into the fine powder storehouse fast through the tubular sieve; The air-flow that impeller rotates generation at a high speed makes simultaneously and can not fall into the meal storehouse through the particle disengaging tubular sieve surface of tubular sieve.
2. vacuum fractionation device according to claim 1; It is characterized in that: motor, transmission mechanism, impeller connect from top to bottom successively; Feeding warehouse, tubular sieve, meal storehouse are communicated with from top to bottom successively, and it is inner that impeller is positioned at the tubular sieve, and the fine powder storehouse is outside at tubular sieve and meal storehouse.
