Abstract

The utility model relates to a mixer used for fixing the material in the fixed vessel, which in particular relates to a mixer with an agitator shaft which does periodic non-uniform speed rotation. The utility model is characterized in that the output shaft of the speed reducing machine is mismatched with the agitator shaft, and an angle alpha is provided between the two, and the rotation between the two are transmitted by a universal joint; therefore, the uniform speed rotation of the output shaft of the speed reducing machine is turned into the periodic non-uniform speed rotation of the agitator shaft. And the flow field of the mixed liquid is changed, and turbulent flow is emerged. The formation of the cylindrical poor rotary motion area is destroyed, and the ideal agitation effect is met.

Description

Non-at the uniform velocity mixer

The utility model relates to the mixer that is used for fixing mixing of materials in the container, and particularly a kind of shaft is made the periodically mixer of non-uniform rotation.

The rotation of at present general its shaft of mixer is to rely on motor, reductor as motive power, connects by shaft coupling, rotates evenly.In the whipping process, easily form cylindric tow-away zone, this regional material does not have relative motion, almost turns round with same angular speed with shaft, so mix bad.

The purpose of this utility model provides a kind of energy-efficient non-at the uniform velocity mixer, and incorporation time is shortened, and mixing effect is good.

In order to achieve the above object, the technical solution that the utility model adopts is as follows: a kind of non-at the uniform velocity mixer, comprise motor, reductor, frame I, frame II, shaft, agitator, and also comprise the universal joint that connects speed reducer output shaft and shaft.

After the utility model has adopted above-mentioned parts, because angle [alpha] in the upper flange plane of frame I and following normal plane inclination, make speed reducer output shaft and the shaft same angle [alpha] that also tilts, passing through between the diaxon---universal joint connects, according to the drive characteristic of universal joint to the diaxon that intersects the α angle, make output shaft obtain periodic non-rotation at the uniform velocity, do identical motion with regard to having driven like this with the agitator that shaft is connected, thereby changed the flow field of liquid in container material, non-particle flux has at the uniform velocity destroyed the formation of cylindric bad tow-away zone, produce turbulent flow, reached the purpose of improving mixing effect.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is an application example of the present utility model

As shown in Figure 1, the utility model comprises motor 1, reductor 2 (its output shaft is 3), universal joint 4, frame I5, frame II6, shaft 7, agitator 8.The high speed rotating of motor 1 is the required working speed of output shaft after reductor 2 slows down, and passes through between its output shaft 3 and the shaft 7---and universal joint 4 transmits motion.Since the upper flange surface of frame I5 and lower flange face tilt one angle [alpha], make the α angle that the axis of the axis of output shaft 3 and shaft 7 has also tilted same, for certain α angle (α usually≤30 °), universal energy-conservation transmission campaign, but its angular speed will change, and the α angle is big more, change big more, so the rotational angular velocity of shaft 7 will change, each transfers one to and changes week, has so just obtained the periodically variable uniform rotation of burying.And agitator 8 is connected on the shaft 7, also just along with doing non-uniform rotation, this stirs material, particularly liquid agitation is very favourable, and it can be eliminated or destroy when stirring operation, stirs axial cylindric bad tow-away zone, suddenly neglecting slow flow field soon impels the liquid of no relative motion to produce turbulent flow, accelerate collision of molecules, and strengthen mixing effect greatly, shorten the time of stirring operation.

Fig. 2 is an example of the present utility model.Since the disalignment of the axis of rotation of shaft and container one angle [alpha], can fully phase out in the container that mixing effect is improved in flow field for a change and the baffle plate (not drawing among the figure) that is provided with, promptly having saved power consumption (generally increases after the baffle plate, power can double above), can reach the shortening mixing time again, improve the effect of mixing effect.

Claims

1, a kind of non-at the uniform velocity mixer comprises motor, reductor, frame, shaft and agitator, it is characterized in that the angle [alpha] that tilted between the output shaft 3 of reductor 2 and the shaft 7, utilizes universal joint 4 to transmit rotation between them then.

2, non-at the uniform velocity mixer according to claim 1, the upper and lower flange face that the it is characterized in that frame I5 angle [alpha] that tilts makes the same angle [alpha] that also tilted between speed reducer output shaft 3 and the shaft 7, and the intersection point of two axis promptly is the center of universal joint 4.
