The described hollow rotating shaft is cover-mounted on the outside of rotating shaft, its lower end is equipped with stator assembled on the emulsifying head.

Description

A kind of composite stirring equipment
A kind of composite stirring equipment of the design belongs to food, the stirring of chemical industry, emulsifying device.
Now high shearing mixing emulsor is generally adopted in the stirring and the emulsification of chemical industry material, this mulser is by frame, and emulsifying head two major parts are formed, and wherein the emulsifying head part is made up of the rotor and the stator of high speed rotating.Under the driving of motor, the high speed rotor rotated sucks region trochanterica with material from container bottom, bears strong immixture, and material throws away from stator hole after being forced through the stator and rotor clearance of precision-fit.Because the violent machinery and the shear action of fluid power, material particles is torn and pulverizes, and meanwhile new material is sucked into rotor center, has finished a circulation.
It is fine that this mulser is used for stirring the less material effect of viscosity, but when being used for stirring full-bodied material, effect is not fine, and material is easy to stick on the still wall; In addition, when needing to heat in the process of making cosmetics or cooling off, the heat transfer of full-bodied material is obviously not enough.Existing solution is that a gate stirrer is set on kettle cover, the center line of the axle of agitator and the central lines of kettle, a high-shear emulsifying device is set on kettle cover then again, and the shaft axis of the emulsifying head of this emulsifier becomes an acute angle with the center line of kettle.This machine is called compound mixer, and it both can utilize the emulsification of emulsifier to material, and the refinement material can utilize the material that adheres on the scraper plate scraping still wall on the gate stirrer again, and strengthens the material heat transfer, is beneficial to cooling or heating.
What the present invention relates to also is a kind of compound mixer, but the design's difference is the dead in line of the axis and the high-shear emulsifying head of agitator.This composite stirring equipment problem to be solved is with originally independently gate stirrer and high-shear emulsifying device were integrated separately, specifically, exactly will be original separately independently the rotating shaft of the shaft of gate stirrer and emulsifier manufacture the composite stirring equipment that coaxial line rotates, have the function that frame stirs and the emulsification function of emulsifying head simultaneously.
At " mixing apparatus design " (wangkai, Feng Lianfang work, China Machine Press, P45) in the book, once mentioned the he industrial group of Japanese U.S. and the combination of three kinds of agitators of gondola PRESSINDUSTRIAL CHEMICAL EQUIPMENT company's production, this agitator is driven respectively by the shaft of three coaxial lines, outermost layer is the frame impeller that has the polytetrafluoroethylene scraper plate, the second layer is the dasher that comprises three layers of impeller, and this agitator is with the direction rotation opposite with gate stirrer; The stirring of innermost layer drives the rotor of emulsifying head.The fixed axis that this mixer also will be provided with a coaxial line specially is used as the stator of emulsifying head.This equipment is too complicated, cost height, inconvenient maintenance.
The product difference of the design's characteristics and above-mentioned foreign producer is only to comprise the shaft of two-layer coaxial line, a shaft drives gate stirrer, another shaft drives the rotor of emulsifying head, and, do not need to be provided with specially the stator that fixed axis is used as emulsifying head, but stator directly is fixed on the shaft of gate stirrer.
At home, also do not have manufacturer production and the compound mixer of selling this coaxial line on the market, do not have this external series products to sell yet in Chinese market.My company designs and makes the compound mixer of this coaxial line at home first.
The design's purpose is that the external structure of a kind of ratio of design is simpler, the coaxial line composite stirring equipment that reliability is high.The problem that solves is: coaxial line is made in the rotating shaft of high-shear emulsifying head and the rotating shaft of gate stirrer, and the stator of emulsifying head is fixed in the rotating shaft of gate stirrer, allow the stator that rotates replace special fixing stator.
The design's implementation method: a motor is installed in vertically on the lid still of stirred tank, motor shaft connects with the rotating shaft of an emulsifying head by a shaft coupling, and the rotor of this rotating shaft and emulsifying head is fixedly connected, thereby drives the plug knife work of emulsifying head; In this rotating shaft, be with a hollow rotating shaft and a hollow worm-wheel shaft, hollow rotating shaft and hollow worm-wheel shaft abutting end are fixedly connected, between rotating shaft outer surface and the hollow rotating shaft inner surface or between rotating shaft outer surface and the hollow worm-wheel shaft inner surface rolling bearing is being set, to keep coaxial line running between rotating shaft and hollow rotating shaft, the worm-wheel shaft; On hollow rotating shaft or worm-wheel shaft outer surface, be with rolling bearing, this rolling bearing is fixedly mounted on the bearing block, bearing block is fixed on frame or worm screw punch-out equipment frame or their fixed coupling unit, frame or worm screw punch-out equipment frame are fixed on the kettle cover, can make the hollow rotating shaft axis and stir the kettle central lines in the still covering position by regulating frame.Establish a motor in addition with the orientation of above-mentioned motor quadrature outside kettle, the rotating shaft of this motor links by shaft coupling and a worm screw, and worm screw drives this hollow rotating shaft slow rotation with the worm gear composition Worm and worm-wheel gearing that is fixed on the hollow worm-wheel shaft; The stator of emulsifying head is set in the lower end of described hollow rotating shaft, and the rotor of this stator and emulsifying head is formed emulsifying head, during this emulsifying head work material is carried out emulsification and stirring.Because the hollow rotating shaft rotating speed is very little, general below 30 rev/mins, the rotation direction of hollow rotating shaft is identical with emulsifying head rotating shaft rotation direction or all can on the contrary.Be fixed with gate stirrer on the hollow rotating shaft of slow rotation, kettle is carried out scraping, simultaneously the material in the kettle is stirred.Be provided with mechanical sealing member between the rotating shaft of emulsifying head and the stator seat sliding surface, prevent that the material in the still from entering in the hollow rotating shaft; Be provided with mechanical sealing member in the cavity between hollow rotating shaft and the seal cover, prevent that the material volatile component from entering in the worm screw punch-out equipment frame.
The design compares with the compound mixer of the different axis on the existing market, and more compact structure, emulsifying power are higher, compare with this external kind equipment, and structure is simpler, safeguards more convenient.
