Description

[Detailed description of the invention] The present invention relates to a continuous stirring device.

For example, in the past, as a device for stirring various liquids, liquid viscous substances, finely divided solids, and other fluid substances, stirring blades or stirring arms were generally provided inside the vessel, and a stirring blade or stirring arm was generally provided inside the vessel. Some devices are designed to stir and mix materials to be stirred to obtain various true solutions or glue-like solutions, but such stirring devices are capable of stirring and mixing materials to be stirred to obtain various types of true solutions or glue-like solutions. Although it is possible to obtain a fairly homogenized stirred product if the stirring is done for a sufficient amount of time, if the product is taken out continuously, the stirring may be uneven in some parts. It was inevitable that it would happen.

Therefore, the inventor of the present invention fixed a rotary disk and a stationary disk, each having a large number of protrusions and small holes, alternately to the rotating shaft and the vessel body, and created a stirring chamber between them, extending from one end of the vessel to the other. We have developed a continuous stirring device (Utility Model Publication No. 10599/1983) that eliminates the drawbacks of the conventional devices by developing a continuous stirring device during sequential quantitative feeding. Although this device is suitable for continuous stirring and mixing of liquids and liquids or liquids and finely divided solids, since the raw materials pass through the small holes provided in the rotary disk and the fixed disk, the mixed material are simply mixed together, and the mixing accuracy is rough.
As a result, in the case of mixing aqueous and oily raw materials,
Sometimes it was insufficient to reach an emulsified state.

In view of this, it is an object of the present invention to further improve the above-mentioned device and provide a continuous stirring device that can sufficiently stir and mix one raw material to a completely emulsified state when mixing another raw material. In this method, one raw material is cut and atomized around the rotary disc, premixed by the cutting disc, and then mixed with other raw materials before reaching the stirring chamber composed of the rotary disc and the fixed disc. The desired purpose can be achieved by stirring in the stirring chamber.

The present invention will be described below with reference to embodiments shown in the drawings.

The outer surface of this partition 14 faces the raw material supply path 5, and the raw material to be pumped is fed through the fine holes 15,
15... to the stirring chamber 8 via the small hole grooves 11, 11...
It is designed so that it flows into the interior. 16 is an outlet for taking out the stirred material.

Next, the operation of the above embodiment will be explained.

The raw material is supplied to the back of the rotary disk 6A through the raw material inflow path 4, and the raw material is supplied to the outer surface of the partition plate 14 through the raw material inflow path 5.

The raw material that has arrived behind the rotary disk 6A is transferred to the cutting disk 1.
The liquid directly enters the stirring chamber 8 between the spacer 2 and the partition plate 14, and enters the small hole groove 11 on the outer periphery of the cutting plate 12. The raw material flows into the first stirring chamber 8 through the pores 11, 11, . . . of the partition 14. This raw material is the pore 1 of the partition 14.
5, 15... into the stirring chamber 8, it is shredded into fine particles by the cutting blade 13 of the cutting board 12 that rotates in sliding contact with the inner surface of the partition 14, and as described above, the small particles of the cutting board 12 are The raw material flowing into the holes 11, 11... is premixed within these small holes 11, 11.... In the stirring chamber 8, the shredded raw materials and the raw materials are stirred and mixed by the protrusions 9, 9, . . . of the rotary disk 6A and the protrusions 10, 10, .

The stirring material flowing from the stirring chamber 8 passes between the inner circumference of the fixed plate 7 and the outer circumferential surface of the rotating shaft 3, enters the adjacent stirring chamber 8, and is similarly stirred and mixed by the protrusions 9 and 10. After that, it is sequentially stirred and the outlet 1
7 is taken out continuously.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the raw material is supplied in the axial direction, and the partition plate 14 is provided in a direction perpendicular to the axis, so that the raw material is supplied in the axial direction. so that this partition 14
This is a modified example in which a cutting board 12 is slidably contacted on the inner surface side of the cutting board 12. As shown in FIG. 4, a cutting plate 12 having cutting blades 13 in the radial direction is fixed to the rotating shaft 3 in this embodiment by a set screw 19.
