Background technology
Polymeric kettle is the capital equipment of preparation macromolecular compound, generally be vertical type cylinder shape autoclave, have chuck, so that feeding steam or cooling water heat or cool off, be used for emulsion polymerisation, in stainless horizontal paddle agitator is arranged, by transmission device and decelerator transmission, the outer wall of still carbon steel commonly used is made by motor, inner liner stainless steel, lining enamel is also arranged, can produce in single still gap during polymerization, many stills series connection are produced continuously.Polymerization reactant enters the top of next still by the bottom of a still, and instrument such as temperature, pressure and feed inlet and outlet etc. are housed on the still.
In the prior art, polymeric kettle generally is made up of kettle, chuck, agitator, transmission device, gland seal device, supporting etc.Wherein, aspect the agitator design of polymeric kettle, what use at most is single ribbon, but single ribbon exists running unstable, short deadly defect of axle envelope life-span; And the power of agitator of two ribbons is bigger than normal, and there be limited evidence currently of adopts.In addition; because carrying out along with polymerisation; the viscosity of polymerization system constantly increases; particularly in the condensate of heavy polymer, polymerization viscosity is higher, adopts conventional agitator type at polymer; produce " pole-climbing " phenomenon through regular meeting; high-viscosity material can stick on the agitator, along with agitator rotates together, so just makes agitator lose the function that stirs and disperse reaction mass.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of improved polymeric kettle is provided.
For solving above technical problem, the utility model is taked following technical scheme:
A kind of polymeric kettle, it comprises the kettle with charging aperture and discharging opening, be arranged on the chuck of kettle periphery, agitator, the axle envelope, transmission device, described agitator comprises the main shaft that is in transmission connection mutually with transmission device and can rotates around himself axial line, be centered around the main shaft bottom, with spiralling to the right first hurricane band of uniform pitch helix mode with in uniform pitch helix mode to left-hand screw rising and shape second hurricane band identical with described first hurricane band, and be fixedly installed on the main shaft and be positioned at the framework of described first hurricane band and the second hurricane band periphery.
According to a preferred implementation of the present utility model: described framework comprises and is horizontally fixed on the main shaft and is positioned at first hurricane band and the housing bar that cross bar, upper end and the cross bar of second hurricane band top are fixedly connected, the inside casing bar that is positioned at housing bar inboard, and fixedly connected with cross bar in the upper end of described inside casing bar, the bottom of bottom and described housing bar is fixedly connected.
According to further preferred version: described housing bar is pressed close to the inner surface of kettle, and the inner surface of the shape of housing bar and kettle is identical makes that the gap between housing bar and the kettle is even.
According to a concrete aspect of the present utility model, to form at the bottom of the still of described kettle by cylindrical still body, kettle cover and taper, the top of housing bar is parallel with the inwall of still body, and the bottom of housing bar parallels with inwall at the bottom of the still.Described charging aperture is opened on the kettle cover, and discharging opening is opened in the middle position at the bottom of the still, and the place is provided with bottom (head) at described discharging opening, and agitator also comprises the end scraper that is arranged on the main shaft bottom, and the shape of this end scraper is similar to the curved surface of bottom (head).
According to another concrete aspect of the present utility model, be provided with a plurality of deflectors that distribute along its bearing of trend in the described chuck.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
According to the agitator of polymeric kettle of the present utility model, it is provided with framework in traditional two ribbons periphery, and can effectively avoid material is " pole-climbing " effect at center with the axle.When stirring, the piercing property that is positioned at inboard two ribbons is good, and the material that the rotation of double helix band drives the still center is done above-below direction and radially mobile; And the rotation that is positioned at the framework in the outside can fully drive the motion of the material that departs from the still center.Therefore,, can improve the mixing stirring and the dispersion effect of material in the still, improve the homogeneity of polymerization reaction system, thereby guarantee the effect of carrying out and improve polymerisation smoothly of polymerisation by the collaborative stirring action of double helix band and framework.
