Description
Technical field
The utility model relates to a kind of Novel mixer syndeton, is specifically related to a kind of clean agitator of removable sanitation-grade that can be applicable to the mixing occasion of the industries such as pharmacy, raw work, food, light industry.
Background technology
In fields such as pharmacy, food, raw works, often require design, type selecting and the installation etc. of production equipment to meet the GMP requirement of sanitation-grade facility level, equipment surface is bright and clean level and smooth, easy to clean, device structure is as far as possible simple, need the parts of cleaning and sterilizing to be easy to dismounting, the moving-members such as the inner member of equipment and agitator must prevent accumulating of material and avoid cleaning dead angle.The agitator using on tradition chemical field often adopts the mode that key is connected to carry out moment of torsion transmission, and by holing on wheel hub and shaft, with securing members such as holding screws, agitator is axially fastened.There is a large amount of buildup spaces and clean dead angle in the positions such as the keyway of conventional agitator, screwed hole, its conventional syndeton obviously can not meet the sanitation-grade designing requirement of the industries such as pharmacy, food.
In order to meet GMP requirement, the agitator that sanitation-grade equipment is used is often cancelled wheel hub, adopts the agitator structure that stirrer paddle and shaft are welded.But this kind of agitator structure is only less in agitator oar footpath, stirred vessel leaves under the occasion in enough turnover space and just can apply, otherwise the shaft that is welded with stirrer paddle cannot be put into stirred vessel smoothly.On stirred vessel, adopt vessel flange structure to address this problem, but the raising that has brought undoubtedly material and production cost has also increased the workload that equipment is installed simultaneously greatly.In addition, cannot dismounting after adopting this structure also to exist stirrer paddle and shaft to be welded, after shaft welding, easily produce distortion and have residual stress, agitator cannot be realized the deficiencies such as maximization.
In order to address this problem, patent ZL201120261665.X has proposed sanitary stirrer syndeton, the effect that substantially realizes disassembled simply and eliminate corner or spot as yet untouched by a clean-up campaign.But this kind of agitator structure is in the connection of wheel hub and shaft, adopt and on wheel hub and axle, radially open respectively screwed hole and screw hole, use holding screw and cover type nut to carry out fastening method, in screw thread/nail hole and acorn nut end face still there is certain dead angle hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of can solve the limitation of conventional agitator in the design of sanitation-grade equipment, has realized not only simply dismounting but also can avoid the sanitation-grade cleaning agitator of corner or spot as yet untouched by a clean-up campaign completely.
The technical scheme taked is for achieving the above object: the clean agitator of a kind of sanitation-grade, comprises shaft, stirrer paddle, wheel hub, seal connector, key, upper end gasket seal and lower end gasket seal etc.
As preferred version of the present utility model, stirrer paddle is directly welded on wheel hub.
As preferred version of the present utility model, center, shaft lower surface is processed with internal thread hole, and the thread rotary orientation of internal thread hole is contrary with the direction of rotation of agitator.
As preferred version of the present utility model, external thread structure is processed in seal connector upper end, and the internal thread hole of externally threaded size and thread rotary orientation and shaft is consistent; The external diameter of seal connector mid portion and the internal diameter of wheel hub are matched in clearance, and process keyway; Seal connector lower end is provided with boss, and the external diameter of boss equates with the external diameter of wheel hub.
As preferred version of the present utility model, between wheel hub and seal connector, by key, be connected, realized the transmission of agitator; Between shaft and seal connector, by matching thread, connect, solved the problem of the axial restraint of agitator.
As preferred version of the present utility model, between wheel hub upper surface and shaft lower surface, gasket seal is all housed between wheel hub lower surface and seal connector raised head face, can prevent that material from entering the space in wheel hub inside and axle upper screwed hole, can eliminate dead angle completely.
The beneficial effect of the clean agitator of sanitation-grade that the utility model provides is:
One, the utility model adopts special seal connector structure, and the application of matching thread in combined axis has completed the axial restraint of agitator; It is contrary with the direction of rotation of agitator that the thread rotary orientation of matching thread is designed to, and effectively solves the locking problem of agitator.Syndeton of the present utility model is easy to dismounting, solves traditional sanitary stirrer and need be welded on axle, is difficult for installing and cannot realizing the shortcoming of maximization; Avoid opening screwed hole/set screw hole on wheel hub and shaft, eliminate the dead angle hidden danger at this place.
Two, described agitator structure letter is gathered, and the mating surface place there is clean dead angle, is all equipped with gasket seal, has stopped the possibility that defective material enters agitator inside completely, meets the requirement of thoroughly cleaning, sterilizing, sterilization in pharmacy and food service industry.
