Abstract
A screening body structure of a screening device for manufacturing medicine comprises bearing seats, a main shaft, shaft sleeves, screw rods, screening plates and a motor. The bearing seats are fixedly arranged at the two ends of a shell body. The main shaft is arranged on the bearing seats in a supporting rotation mode. The end portion of the main shaft is in power connection with the motor. Three shaft sleeves penetrate through the main shaft. Six screw rods distributed in a ring line mode are vertically welded on the outer wall of each shaft sleeve. The screen plates are arranged on end portions of the screw rods through threads and constitute a six-face conical screening barrel structure, and the conicity of the screening barrel is 12 degrees. A feed inlet feeding toward the screening barrel structure is formed in the shell body on a small-caliber side of the screening barrel structure. A discharge outlet is formed in the lower portion of the shell body at the large-caliber end of the screening barrel structure. A secondary filter screen is arranged on the shell body on the lower portion of the screening barrel structure. The screening device greatly improves screening efficiency, and ensures product quality.
Description
Technical field
The utility model relates to a kind of pharmaceutical equipment, is specifically related to a kind of pharmaceutical purpose screening plant.
Background technology
At present, in pharmaceutical manufacturing, screening plant is very crucial a kind of equipment, and in solid chemicals, powder medicament production process, the effect of playing is particularly crucial.
Most vibratory sieve or the drum sieves of adopting of existing screening plant, relatively simple for structure, screening mode is also more single, by the vibrations of screen cloth, solid chemicals is distinguished exactly.But the screening plant that these are traditional, is running into screening materials carrying humidity, ratio of viscosities when larger, the screening that is difficult to be well on, causes screening effect very poor, has reduced the quality of product.
Utility model content
The technical problem that the utility model solves is to provide a kind of pharmaceutical purpose screening plant, thereby solves the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of pharmaceutical purpose screening plant, comprise housing, in described housing, be rotatablely equipped with sieve nest structure, described sieve nest structure comprises bearing block, main shaft, axle sleeve, leading screw, sieve plate and motor, described bearing block is fixedly installed in the two ends of described housing, and in order to support rotating, described main shaft is installed, the end power of described main shaft is connected with described motor; And on described main shaft, be equipped with three axle sleeves, on described axle sleeve outer wall, be vertically welded with the leading screw that six circular rows distribute, the end of described leading screw utilizes screw thread that described sieve plate is installed, described sieve plate forms six pyramidal screen drum structures, and tapering is 12 degree, discharging one end of described sieve plate is provided with inwardly protruded back-up ring; On the described housing of the small-bore side of wherein said screen drum structure, be provided with to the charging aperture of described screen drum structural charge; The described lower housing portion of described screen drum structure heavy caliber one end offers discharging opening, and the described housing that is positioned at described screen drum structure bottom is provided with secondary filter net.
In the utility model, between described motor and described main shaft, be provided with reductor.
Principle of the present utility model is as follows: six pyramidal screen drum structure revolutions under motor drives, material is flowed into from small-bore one end of screen drum structure by charging aperture, because screen drum structure has the effect of certain tapering to material thrust and sieve aperture, material rolls forward along small end, fine grain material spills and falls into hopper discharge from sieve aperture, by conveying equipment, sent in storehouse, the material of bulk rolls into discharging opening discharge from screen drum structure and carries out broken again.
Owing to having adopted above technical scheme, the utlity model has following beneficial effect:
On main shaft of the present utility model, be equipped with three axle sleeves, on described axle sleeve outer wall, be vertically welded with the leading screw that six circular rows distribute, the end of described leading screw utilizes screw thread that described sieve plate is installed, and described sieve plate forms six pyramidal screen drum structures, and tapering is 12 degree; On the described housing of the small-bore side of wherein said screen drum structure, be provided with to the charging aperture of described screen drum structural charge; The described lower housing portion of described screen drum structure heavy caliber one end offers discharging opening, and the described housing that is positioned at described screen drum structure bottom is provided with secondary filter net.Based on above structure, inventor finds in practice, when the humidity of solid chemicals and viscosity are when larger, is not easy the phenomenon that occurs that sieve aperture is blocked, greatly improved the efficiency of screening, guaranteed the quality of product simultaneously.
