Abstract

The utility model relates to an agitating device for material mixture in fixed container, in particular to the vertical-type, side-in type or bottom-in type agitating device with periodic oscillation. The utility model comprises a motor, a speed reducer, a mixing shaft, and a mixing impeller which are in transmission connections. A shell body of the speed reducer is hinged with a flange fixed on the mixing container, and a swaying mechanism which enables the mixing shaft to sway periodically as well as a flexing sealed mechanism are arranged between the shell and the flange. The useful effectiveness of the utility model lies in that: because the connection between the shell of the speed reducer and the flange adopts the swaying mechanism, the mixing shaft can periodically sway while in rotation. Thus, the utility model has the advantages of even mixing and good effectiveness.

Description

The efficient agitating device of periodic wobble

Technical field:

The utility model relates to the agitating device that is used for fixing mixing of materials in the container, particularly inserts vertical, the side feeding type or the bottom entering type mixer of the periodic wobble of variable-angle.

Background technology:

Present used mixer, no matter be that employing is vertical, or side feeding type or bottom entering type, it inserts angle all is certain, and in a single day the material flow pattern that forms in the container forms, and just can not change, therefore the stirring defective region in container easily forms the accumulation of material, particularly for irregular container, increase along with it stirs defective region, the trend of material deposition is more obvious.

Summary of the invention:

But being exactly a kind of periodically-varied that proposes at the problems referred to above, the utility model inserts the periodic wobble mixer of angle.

The technical scheme in the invention for solving the above technical problem is: the efficient agitating device of periodic wobble, comprise the motor, reducing gear, shaft, the agitator arm that are in transmission connection successively, the housing of reducing gear is articulated and connected with the flange that is installed on the stirred vessel, and between them, be provided with the swing mechanism that makes the shaft periodic wobble, between shaft and flange, also be provided with scalable sealing device.

The beneficial effects of the utility model are: owing to adopt pendulous device to be connected between the housing of reducing gear and the flange, make shaft when rotating, but periodic wobble thereby have and stir effective advantage also.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment mixer;

Fig. 2 is the partial top view of Fig. 1;

Fig. 3 is top dead centre (limit) position;

Fig. 4 is lower dead center (limit) position.

The specific embodiment:

As shown in the figure, present embodiment comprises motor 1, and reducing gear (comprises yielding coupling 2, bevel pinion 3, bevel gear wheel 5), shaft 9, ball supports 6, built-in whole machine envelope 4, sylphon seal 7, device for plugging 8, impeller 10, bearing pin 11, the housing 16 of reducing gear is hinged with flange 17 by bearing pin 11, can be around bearing pin 11 swings.Shaft 9 is in transmission connection with reducing gear, goes back turning set in the outside of shaft 9 and is provided with axle sleeve 18, and the endoporus of axle sleeve 18 and Ball support 6 closely cooperates and is fixed on the housing 16, and the sphere of Ball support 6 then is connected with flange 17 elastic packings.Be provided with pendulous device between housing 16 and flange 17, Ball support 6 both can improve the rigidity of support of axle, can play the leak stopping effect again when sylphon seal 7 was lost efficacy.The quick change of the convenient built-in whole machine envelope 4 of device for plugging makes it and material in the container all need not be emitted.The leather bag sealing is adopted in sylphon seal 7, stays corresponding stretching, extension surplus according to amplitude of oscillation size.

Output shaft axle envelope adopts built-in whole mechanical seal 4, is characterized in that rotating ring is positioned at side medium, and stretch compensation mechanism is installed on the stationary ring, and material can be selected SiC-SiC for use, and a material is sealed with good effect.Sylphon seal 7 is adopted in the swing sealing, and this sealing is converted into the stretching routine of seal bellows itself and the static seal of bellows and associated components with the movable sealing pattern of swing, and sealing is reliable.Choosing of bellows material, can use acid and alkali-resistance rubber, as silicon rubber, fluorubber etc. can adapt on the stirring application requirements of any medium substantially.If in the bigger container of pressure, then can consider to select for use metal bellows to make encapsulant.

The oscillation cycle pendulous device comprises connecting rod 12, crank 13, and bearing pin 14, connecting rod 12 is hinged with housing 16 and crank 13 with pin 14, and crank 13 is driven by deceleration device 20.5 the bearing pin connecting holes that drill and ream on crank 13 different distributions circumference are to regulate the usefulness of the amplitude of oscillation.By adjusting the link position of crank and connecting rod, amplitude of fluctuation can be selected between 5～30 ℃, according to the shape and the size of container, selects the suitable amplitude of oscillation, to reach best mixing effect.
