Abstract
The invention provides a strip hole drum screen device. The strip hole drum screen is composed of a rotating drum 1 and a screen handle 2, wherein the rotating drum 1 comprises an inner screen barrel 3 and an outer screen barrel 4, and the inner screen barrel 3 and the outer screen barrel 4 are molded by strip hole stainless steel screen plates in a curved mode and are concentric cylinders. The screen handle 2 runs through the rotating drum 1 and is fixedly connected with two end planes of the rotating drum 1. The width of a surface strip hole of the inner screen barrel 3 corresponds to the maximum of a pill standard diameter range, the width of a surface strip hole of the outer screen barrel 4 is smaller than the width of the strip hole of the inner screen barrel 3 and corresponds to the minimum of the pill standard diameter range, and the length of the strip holes is determined by the size of the screen barrel. The strip hole drum screen has the advantages that the effective separation of big, medium and small pills is achieved, the screen holes cannot be blocked, the separation thoroughness and production efficiency can be controlled by the speed and turn-around time of the rotating barrel, accuracy and convenience performance are good, and the production efficiency is improved.
Description
Technical field
The present invention relates to the screen selecting and separating mechanism field of spherical pellet, particularly the screen selecting and separating mechanism of pharmaceutical industry or food service industry spherical pellet.
Background technology
At present at pharmaceutical industry, the equipment that screening separates the wetting pill of spherical flowable of diameter inequality is all to adopt single or multiple lift circular hole or square hole horizontal screen, and the sieve nest motion mode has reciprocal plane motion, vertical vibration and comprises plane motion and the compound concussion campaign of vertical vibration.But, which kind of screening mode no matter, all because spherical pill makes the wetted portions pill of moderate dimensions that sieve aperture is partly or entirely stopped up greatly with sieve aperture periphery contact-making surface, and the phenomenon that can't remove, cause having to stop in production the cleaning sieve aperture, brought adverse influence to production.
Summary of the invention
The purpose of this invention is to provide a kind of bar hole drum sieve device.
Structure of the present invention comprises: a kind of bar hole drum sieve device, formed by rotating cylinder 1 and sieve handle 2, and rotating cylinder 1 comprises interior sieve bucket 3 and outer sieve bucket 4, by bar hole stainless steel sieve plate bending forming, interior sieve bucket 3 is concentric drums with outer sieve bucket 4, and sieve handle 2 runs through rotating cylinder 1, is fixedly connected with rotating cylinder 1 end flat.
Interior sieve bucket 3 surperficial bar shaped hole widths are corresponding with pill normal diameter scope maximum, and outer sieve bucket 4 surperficial bar shaped hole widths are less than interior sieve bucket 3 bar hole width, and are corresponding with pill normal diameter stated range minimum.
The length of bar hole determines by screen drum size, and in general in the situation that do not affect the length that sieve intensity should be tried one's best, with the raising amount of sieving, the arrangement of bar hole gets final product " to the hole " also can " wrong hole ", tight as far as possible under possible condition.
The workflow of bar hole drum sieve device is: the bar hole sieve is rolled into screen drum, and artificial hand reciprocating gird cylinder rotates or the driven by motor revolution, makes pill in interior upset; Screen drum is two-layer, and the pill of diameter maximum is at internal layer, and the medium qualified pill of diameter is in the middle level, and minimum pill is at skin, and special exports is set each layer so that production continuously.
The operation principle of bar hole drum sieve device is: use two-layer bar hole drum sieve, the uneven pill of size is placed in interior screen drum, when rotating, screen drum forms relative motion between pill and sieve bucket, diameter moves to skin less than the pill of sieve bucket oblong aperture width by sieve plate, and diameter has been stayed inner core greater than the pill of laying particular stress on of sieve aperture width; In the middle level, namely, screen drum pill outer, that outer screen drum is interior has screened outermost layer to diameter pill less than normal again through same principle, realized effective separation of large, medium and small pill, the width design of inside and outside screen drum bar hole just can be designed accurately as long as measure the diameter range of qualified pill, determine according to the scope of qualified pill diameter, a kind of spherical pill weight acceptability limit records ball heavily for the diameter of X is A in the X-Y scope, outer sieve bucket bar hole width is decided to be A; Recording the heavy diameter of Y ball is B, and an interior sieve bucket bar hole width is decided to be B.
The invention has the beneficial effects as follows: realized effective separation of large, medium and small pill, can not stop up sieve aperture, and completeness and the production efficiency of separating can be controlled by rotor speed and gyration time, accurately convenient, enhance productivity.
