The present invention relates to a homogenizer for uniformly dispersing particles in a liquid.

When manufacturing suspensions of beverages, paints, polishing liquids, etc. in production plants related to food, chemicals, semiconductors, liquid crystal displays, etc., and when such suspensions are left for a long time, precipitation occurs. In the case of reuse, homogenizers are usually used when the particles precipitated and aggregated in a liquid must be uniformly dispersed.

The homogenizer 1 of this kind, which is widely known in the art, has a drive device 15, a pair of left and right rotary shafts 13 and 13 which are rotationally driven by the drive device 15, as shown in FIG. And a support housing 14 which is supported while being inclined by the pair of left and right rotation shafts 13 and 13 to support the suspension storage container 10. When the homogenizer 1 is driven by a pair of left and right rotary shafts 13 and 13 by the drive device 15, the support housing 14 that supports the suspension storage container 10 also simultaneously with the rotation, Rotation with a trajectory as shown in FIG. 6 is performed, and the horizontal surface oscillation is made by the vertical movement which occurred at both ends on the axis line while flowing the suspension in the suspension storage container 10 in the anti-rotation direction. It can raise and disperse | distribute the particle in it uniformly.

By the way, in the homogenizer 1 as described above, the method of dispersing particles together with the flow and fluctuations in the predetermined direction formed in the suspension in accordance with the rotation of the suspension storage container 10 is the force of the flow and fluctuations. Due to this small size, only particles or aggregates having low viscosity can be supported, and in particular, the suspension takes a long time and the dispersion effect is very bad for a high viscosity suspension such as a polishing liquid used for polishing a glass substrate in a semiconductor process. There is a continuing need for improvement from the United States.

In view of the above problems, an object of the present invention is to provide a homogenizer which has a quick and excellent effect in bringing particles into a uniform and good dispersion state in a liquid.

In order to achieve the above object, the present invention provides a homogenizer having a container support means for supporting a liquid storage container, and a rocking means configured to support the container support means so as to swing left and right reciprocally. do.

In the embodiment of the rocking means, each of the left and right support means each supporting the container support means from below the left and right sides, wherein at least one of the left and right support means is within a predetermined range on the container support means. The two left and right support means constrained to move left and right and the drive shaft of the motor is connected to the one of the two left and right support means through a crank to vertically move the one support means according to the rotation of the drive shaft. It consists of a motor that can move from side to side.

In the homogenizer according to the above structure, the container supporting means is moved up and down and left and right by supporting the container supporting means in a left and right reciprocating manner, i.e., by one of the supporting means by driving the motor. By oscillating reciprocally in the left and right direction, the liquid in the liquid storage container flows in a reciprocating manner, thereby not only impacting sediment adhered to the inner wall of the container by the flow of each reciprocating movement, but also in the opposite direction during the reciprocating movement. Since it rises and agitates and produces a wave, the impact force to a deposit etc. becomes further intense, and even a deposit with high viscosity can reliably and quickly peel it off and disperse | distributes uniformly.

EMBODIMENT OF THE INVENTION Hereinafter, the homogenizer of this invention is described in detail with reference to an accompanying drawing. 1 is a perspective view of a part in which the homogenizer of a preferred embodiment of the present invention is notched, showing a state in which a homogenizer is installed in a support housing. FIG. 2 is a partially enlarged view showing a configuration relationship between the right support means, the container support means and the motor in FIG. 1. FIG. 3 is a partial longitudinal sectional view of FIG. 1 viewed from the front, for explaining the operation of the homogenizer. FIG. FIG. 4 is a front view showing a state in which the container supporting means in FIG. 1 is rocked with the left rise, and is a view for explaining the operation of the homogenizer. FIG.

As shown in FIG. 1, the homogenizer 2 of this invention is provided in the box-shaped support housing 3. As shown in FIG. The homogenizer 2 is mainly composed of a container supporting means 21, two left and right support means 22 and 23, and a motor 24.

The container support means 21 is an external container 211 which can be opened and closed, and in addition, a liquid storage container 212 having a size to be housed in the external container 211 is provided. Moreover, the left extension plate 213 and the lower extension plate 214 in which the through-hole 214A extended in the left-right predetermined range are extended from the bottom face of the outer container 211, respectively. The liquid storage container 212 can accommodate the suspension 4 such as a beverage, a paint, and a polishing liquid as described above. Moreover, when using the homogenizer of this invention, it is preferable to accommodate the suspension 4 in the state which does not fill the liquid storage container 212 (for example, see FIG. 3).
