Abstract
The utility model provides a detachable hygienic stirrer which is formed by a stirring shaft, a stirring blade, a hub, a sealing cover, a key, a sealing member, a fastener and the like. The stirring blade is welded on the hub which is in key-matching connection with the stirring shaft, and the lower end of the hub is covered by the sealing cover. The key is designed into a unique double-end stair-shaped structure so as to achieve the effect of torque transmission and positioning fastening. All gaps and contact surfaces of the stirrer are provided with sealing members, so that hygienic dead angles are avoided. The hygienic stirrer is easy to detach and optimized in shaft designing, meets the requirements of thorough cleaning, sterilization and disinfection in good manufacturing practice (GMP) specification.
Description
Technical field
The utility model relates to a kind of Novel mixer, particularly, relates to a kind of removable sanitary stirrer that can be applicable to the fields such as pharmacy, biochemical industry, food, light industry.
Background technology
In the fields such as pharmacy, food, biochemical industry, general design, type selecting and the installations etc. that all require production equipment meet the requirement of GMP, device structure should be tried one's best simply, need to clean and the parts of sterilization will be easy to dismounting, all will avoid the existence of dead angle and defective material with any inner member that material directly contacts.In traditional agitator structure, wheel hub and shaft cooperate transmitting torque by key, by holding screw wheel hub is fixed on that to carry out axial location on the shaft fastening, in keyway fit clearance and holding screw screwed hole the dead angle is arranged, can't satisfy the sanitation-grade designing requirement of food, pharmacy etc. at all.
In order to satisfy the GMP requirement, sanitary stirrer often adopts to be removed wheel hub and stirrer paddle and shaft is sealed the structure that is welded, but this structure has too large limitation, be only applicable to the less or kettle in paddle oar footpath and be equipped with the occasions such as vessel flange, agitator could be put in the still smoothly like this.In addition, can't dismounting after this structure also exists wheel hub and agitator and is welded, the agitator height can't be adjusted, and easily produces distortion after the shaft welding and has the deficiency such as residual stress.
Summary of the invention
In view of above problem, the purpose of this utility model is to provide a kind of can solve the limitation of conventional agitator in the sanitation-grade design, realizes not only dismantled and assembled but also can effectively avoid the sanitary stirrer structure at dead angle.Concrete technical scheme is as follows:
A kind of removable sanitary stirrer, described sanitary stirrer comprises shaft, stirrer paddle, wheel hub, seal cover and securing member, described stirrer paddle is fixedly connected with described wheel hub, described wheel hub and described shaft are connected by key, described seal cover passes the bottom that seals described wheel hub behind the described shaft, and described seal cover is fastening with described securing member.
Described key has the two ends stepped construction, but both transmitting torques can be realized again axial location and the fastening effect of wheel hub on shaft.This structure can thoroughly solve conventional agitator holding screw tightening, radially opens screwed hole and screw hole on wheel hub and shaft, has avoided having in screwed hole and the screw hole problem of dead angle hidden danger.
Described stirrer paddle is welded on the described wheel hub.
Has O type circle seal between described wheel hub and the described shaft.
Has O type circle seal between described seal cover and the described shaft.
Has spacer seal between described seal cover and the described wheel hub lower surface.
Described securing member is studs, plain washer and acorn nut.
Described plain washer and acorn nut are before fastening, and described studs is set with first spacer seal.
Between wheel hub inner ring and the shaft, between seal cover and the wheel hub lower surface, between seal cover inner ring and the shaft, between acorn nut (containing fastening plain washer) and the seal cover lower surface seal is installed, can prevent that material from entering the space in wheel hub inside and bolt hole, the screwed hole, effectively eliminates the dead angle.
The beneficial effect of the removable sanitary stirrer that the utility model provides is as follows:
1, the special stepped bond structure of both-end of described sanitary stirrer employing, and combination seal lid is finished the axial location of agitator and fastening.This structure is easy to dismounting, solves conventional agitator and is welded on shortcomings such as causing the difficult installation of whole agitator on the axle; Avoid opening screwed hole at wheel hub, eliminate this execution angle hidden danger; Avoid urgent on shaft and decide screw hole, eliminate the shortcoming that screw hole is concentrated weakening and the stress of axle, also can reduce the intended diameter of shaft.
2, the letter of described sanitary stirrer structure is gathered, space and mating surface place the dead angle occurring cleaning all rationally install seal additional, has stopped material in the accumulating of agitator inside, and satisfies the requirement of thoroughly cleaning, sterilization, sterilization among the GMP.

The specific embodiment
Below, further illustrate content of the present utility model in connection with embodiment, but embodiment not limiting protection domain of the present utility model, any improvement of doing based on technical solutions of the utility model spirit all should be within protection domain of the present utility model.
The structure of the sanitary stirrer that the present embodiment is removable as shown in Figure 1, comprise shaft 1, stirrer paddle 2, wheel hub 3, seal cover 4 and securing member (comprise studs 9, acorn nut 10 and between plain washer 11 and minipad 12), stirrer paddle 2 directly is welded on the wheel hub 3, is connected by key 5 between wheel hub 3 and the shaft 1.Key 5 adopts special both-end stepped construction, both can transmit the stirring moment of torsion, can realize again by upper cascaded surface having wheel hub 3 is carried out the effect of axial restraint at shaft 1.This structure can be avoided conventional agitator holding screw tightening, and the problem of dead angle hidden danger is arranged in screwed hole.
Seal cover 4 is fixed on the lower end of wheel hub 3 by securing members such as studs 9 and acorn nuts 10, agitator is positioned on the shaft 1 fully.
O type circle 6 is housed between wheel hub 3 and the shaft 1, can guarantees the inner ring top of wheel hub 3 and the sealing effectiveness between the shaft 1.
Studs 9 is screwed in the bolt hole of wheel hub 3 lower surfaces, shell tool 7, seal cover 4 pass studs 9 and shaft 1 is pressed on the lower surface of wheel hub 3, and minipad 12 and plain washer 11 are successively pierced in the studs 9, uses acorn nut 10 fastening again.Pad 7 and minipad 12 can prevent respectively that material from entering in the bolt hole of the contact-making surface of wheel hub 3 and seal cover 4, seal cover 4.
