Description
Technical field
The utility model relates to a kind of rotary screen equipment, relates in particular to a kind of rotary screen that is used for the Chinese medicine material.
Background technology
The Chinese medicine plant material of flower class, leaf class, whole grass, stem and root class before infusion the screening pre-treatment and infusion after the medicine materical crude slice made or the screening of pill handle, it is one of key link in the Chinese patent drug production process, the screening plant that is adopted is handled in screening, include vibratory sieve, plane rotary screen and manual sieve, wherein preceding two kinds of screening plants only are suitable for the screening of herbal decoction piece and pill to be handled, but is not suitable for the screening processing of the Chinese medicine plant material of flower class, leaf class, whole grass, stem and root class.This is because the Chinese medicine plant material of flower class, leaf class, whole grass, stem and root class is the light material of Chinese medicine, in the light material of Chinese medicine, not only contain a large amount of impurity and silt, and light material is wrapped in by these impurity and silt and forms the light material of the certain thickness bed of material, this light material is thrown in screening process and can not moved, thereby cause screening not thorough, screening efficiency is very low.Though and the screening that can solve above-mentioned light material is sieved in craft, working strength of workers is big, and severe operational environment.Therefore, demand developing a kind of screening plant that is used for the light material of Chinese medicine at present urgently.
Summary of the invention
The purpose of this utility model is to provide rational in infrastructure, a kind of rotary screen that is used for the Chinese medicine material that screening effect is good.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of rotary screen that is used for the Chinese medicine material, comprise the rotary screen cylindrical shell and by reductor, the transmission mechanism that motor is formed, it is characterized in that: described rotary screen cylindrical shell, by the back plate, the back circle, blade, preceding circle, pillar and rear lining plate are formed, Hou Quan and Qian Quan are connected and fixed by pillar, pillar is provided with the spiral helicine blade that is different angles, on the circle of back, be welded with rear lining plate and fixed head, between Qian Quan and back circle and on the cylindrical of screen drum body, be surrounded by screen cloth, screen cloth is fixed on the screen drum body, on the upside of preceding circle and downside position, be respectively equipped with charging aperture and discharging opening, the two cover rollers of device on support are housed in preceding circle bottom, by above-mentioned each connection and fixed part and form cylinder sieve nest assembly and be contained in the casing of sealing, be positioned at casing one side and be provided with the air inducing dust arrester, described transmission mechanism, be designed to the frequency converter timing transmission mechanism, by being contained in the connection power transmission shaft on the plate behind the screen drum body, the reductor that is connected with shaft coupling, the motor that is connected with reductor is formed with the frequency converter that is connected with motor.
Described rotary screen cylindrical shell, its size is set according to screening material characteristic and particle size, and the rotary screen barrel diameter generally is set in the 0.2m-5.0m scope, and length generally is set in the 0.2m-20.0m scope.
Described rotary screen, its speed setting according to the material requirement of being sieved, can be regulated the rotating speed of rotary screen for for 0-100 rev/min by frequency changer.
The blade that is fixed with on the described pillar in the rotary screen cylindrical shell, the number that blade is set is set according to the diameter and the length of rotary screen cylindrical shell, generally sets at least 3 with blade.
Described rotary screen, can according to the classification of sieve material require to be designed to by a plurality of same structures but the cylindrical shell that do not comprise the back circle be concatenated into and arrange the multistage rotary screen of shape, its charging aperture is arranged on circle middle part, back, circle downside before discharging opening is arranged on.
The rotary screen operation principle:
Behind the motor starting, to reductor and rotary screen cylindrical shell, make the rotation of rotary screen cylindrical shell by belt transmission, material enters in the rotary screen from charging aperture.When rotary screen was just changeing, material was advanced by rotating vane and disperses, and constantly stirs, and smalls or silt in the material leach by screen cloth, by air inducing silt dust are sent into dust arrester; In rotary screen when counter-rotating,, the material that blade comes out screening pushes to discharging opening toward the place ahead, and the material that comes out from discharging opening is the clean material after the screening.
Because not only be provided with screen cloth in the utility model structure, but also be provided with the blade that pushes and disperse light material effect, thereby gently material can overturn fully under the effect of blade and flow, thereby fully be sieved, screening effect is good; Owing to also disposed the seal case that air inducing dust arrester and cylinder sieve nest assembly have been contained in dustproof effect, improved the operation element environment greatly.
The utility model structure, reasonable in design, the screening that is not only applicable to the light material of Chinese medicine plant of flower class, leaf class, whole grass, stem and root class is handled, and handles applicable to the screening of tcm and herbal slice or pill.
