Background technology
Granulation is through being processed into the operation with definite shape and size shot-like particle the material of the states such as powder, fused solution, the aqueous solution.Method of granulating can be divided into three major types: wet granulation, dry granulation, spraying granulation, wherein wet granulation is most widely used.Wet granulation adds adhesive in drug powder, powder coalesced together by the crane span structure of adhesive or cementation and prepares the method for particle.The advantages such as the particle surface that wet method is made is moistening, has granular mass good, and good looking appearance, wearability are comparatively strong, compact property is good, are most widely used in medical industry.Wet granulator generally has prilling tower; paddle, granulating cutter and shower nozzle is provided with in prilling tower; adhesive is sprayed on material by shower nozzle equably; liquid in adhesive is by material moistened surface; make to produce adhesion strength between powder, through paddle uniform stirring, material powder is bondd agglomerating; again through the processing of granulating cutter, make the particle of definite shape and size.A kind of granulation being widely used in each pharmaceutical factory is also had to be wet-mixing granulation, its operation principle is: first poured into by material in material pot, then adhesive is added, rotated by the paddle in pot and material and adhesive are mixed fully, then, under the elaboration of shredder bar, finally material particles is formed.At present, general mixer granulator is due to the problem of granulating cutter structure, and the molding effect of material particles is not very desirable; simultaneously; what the reactor due to mixer granulator generally adopted is steel or aluminium alloy structure, causes the heat losses of reactor very fast, thus increases energy consumption.
Summary of the invention
The invention provides the mixer granulator with two granulating cutter structure, solve mixer granulator material particles molding effect in the past not ideal, and heat losses is large, thus the problem causing energy consumption higher.
The present invention is that technical solution problem is achieved through the following technical solutions: with the mixer granulator of two granulating cutter structure, comprise bracing frame and be fixed on the columniform reactor in the middle part of bracing frame, described reactor is provided with the cloche of this reactor of sealing, described cloche is provided with charging aperture, charging aperture is provided with lid, the bottom of reactor is provided with discharging opening, the base plate of bracing frame is fixed with drive unit, drive unit is provided with horizontal rotating shaft and vertical transfer axle, described horizontal rotating shaft is stretched in reactor from the bottom centre of reactor, the front end of horizontal rotating shaft is fixed with the horizontal granulating cutter of yi word pattern, described vertical transfer axle stretches in reactor from the lateral vertical of reactor, the front end of vertical transfer axle is fixed with paddle, the top of support frame as described above is also provided with the drive shaft stretching into inside reactor, the lower end of described drive shaft is provided with vertical granulating cutter, described vertical granulating cutter and horizontal granulating cutter are all positioned at the top of paddle, the outer surface of described reactor is provided with heat-insulation layer.
Described paddle is three leaf oars, and the angle between the adjacent blade of three leaf oars is 120 degree.
Formed by described blade and horizontal plane, angle is 10 ~ 30 degree.
Described vertical granulating cutter comprises cutter, middle blade and bottom knife, and two of cutter is bent upwards, and two of bottom knife is bent downwardly.
Described horizontal granulating cutter is between paddle and the sidewall of reactor.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention adopts two granulating cutter structure, a horizontal granulating cutter and a vertical granulating cutter, horizontal granulating cutter or the single work of vertical granulating cutter can be selected as required, also horizontal granulating cutter and vertical granulating cutter can be selected to work simultaneously, such can according to the characteristic of different material, obtain the material particles that molding effect is ideal.
(2) outer surface of original reactor is provided with heat-insulation layer by the present invention, effectively reduces scattering and disappearing of heat, thus reduces energy consumption.
(3) structure of the present invention is simple, and easy to operate, cost is lower, and practicality is stronger.
