Description

Detailed Description of the Invention The invention is a device for mixing and agitating two or more types of heavy liquids, heavy liquids, or two or more types of liquids with different specific gravities, such as water and oil, A-B-C heavy oil, etc. Regarding.

It is particularly useful as an emulsion device for water and heavy oil. Conventional equipment for mixing heavy liquids and heavy liquids simply rotates blades to stir and mix the liquid, and as the blades rotate, a rotational flow is generated in the liquid, and conversely, the centrifugal force of that rotation causes the liquid to mix. There is a disadvantage that mixing is inhibited by centrifugation, complete mixing cannot be achieved, and it takes time.Also, it is impossible to mix in the form of fine particles on the micron scale, making complete emulsion impossible, and emulsifiers are usually not used. The disadvantage was that it had to be added.

The present invention aims to eliminate such drawbacks and provide an excellent heavy liquid/heavy liquid mixing device that can completely mix fine particles in the micron scale in an extremely short time. The gist of the invention described in claim 1 (hereinafter referred to as the first invention) is that a cylindrical container 1 is provided with a required number of porous fixed partition walls 2.
A fixed partition wall 2 is provided, a porous rotary vane 3 is provided on each side of the fixed partition wall to cause a counterflow toward the fixed partition wall, and a heavy liquid and a heavy liquid are introduced into one end of the container 1. The heavy liquid/heavy liquid mixing apparatus is provided with ports 5 and 6 and a discharge port T for mixed liquid at the other end of the container.

The gist of the invention recited in claim 2 (hereinafter referred to as the second invention) is that in addition to the structure of the first invention, the outer liquid near the inner circumferential wall of the container 1 is placed at a required location in the container 1 on the inner center side of the container 1. This is an additional configuration in which a centripetal flow generation vane 4 is provided to move the blade. No. 1 | 2 Both inventions can be used not only for mixing two or more liquids with different specific gravity, but also for mixing two or more liquids with different chemical and physical properties, or as a simple mixing and stirring device. It is. Further, the rotating blade 3 may have a blade structure of either a screw blade or an axial flow blade. Here, it is desirable to provide the fixed partition wall 2, the pair of rotating blades 3 facing the fixed partition wall 2, and the centripetal flow generating blades 4 as a set in multiple stages in the cylindrical container 1 for more complete mixing. The centripetal flow generating blades 4 may be rotationally driven or fixed blades, but it is preferable that they be rotated and driven. Furthermore, the "porous" material of the fixed partition wall 2 and the rotary blade 3 may be one in which a large number of through holes are punched in the wall plate or blade plate, or may be made of a mesh. The point is these walls.
It is only necessary that there be a large number of voids and a flow of liquid of around 5% in the components of the blade. The heavy liquid and heavy liquid inlets 5 and 6 may be provided with separate inlets or may be supplied by the same inlet pipe. In the figure, 2' indicates a large number of through holes drilled in the fixed partition wall 2, and 3
' is a large number of through holes drilled in the rotating blade 3, 8 is a hole in the rotating blade 3.
a rotating shaft on which the centripetal flow generating blade 4 is attached; 9 a drive motor for the same rotating shaft; 10 a light liquid introduction pipe; 11 a heavy liquid introduction pipe;
Reference numeral 12 indicates a mounting bolt for the fixed partition wall 2, and reference numeral 13 indicates a communication port bored in the center of the centripetal flow generating blade 4.

In this invention, when light liquid and heavy liquid are sent into the container 1 from the inlets 5 and 6, the liquids on both the left and right sides of each fixed partition wall 2 are mutually separated by the porous rotary blades 3 provided on both sides. The liquid flows toward the fixed partition wall 2, and the liquid is stirred and mixed by the collision with the fixed partition wall 2 and the collision between the countercurrents, and at the same time, the rotation component generated with the counterflow of the rotating blades 3 is canceled out, resulting in centrifugal separation. is prevented from occurring.

More importantly, when the liquid passes through the rotating blade 3 and the fixed partition wall 2 and collides with it, the liquid is sheared by the numerous through holes 2' and 3', and the liquid is easily atomized to the order of microns, and the liquid is , oil, etc. can be mixed more completely. By repeating such shearing and collision, the light liquid and heavy liquid are mixed and stirred to achieve a completely mixed state. Furthermore, in the second invention, the liquid near the inner circumferential wall of the container 1 that is centrifuged to the outside of the container 1 due to the presence of some rotational force or the liquid that has been separated by specific gravity is transferred to the inside of the container 1 by the centripetal flow generating blades 4. Forcibly pull back to the center,
Shearing and collision are repeated by the rotating blades 3 and the fixed partition wall 2, and a portion is sent from the communication port 13 to the next stage of the fixed partition wall 2 and the rotating blades 3, thereby repeating the above-mentioned mixing process. The mixed liquid is discharged from the discharge port 7 when the mixing is complete. As mentioned above, book 1
According to the invention of , 2, a pair of porous rotary blades 3K that generate counterflows across the porous fixed partition wall 2 cause the liquid to collide with each other in opposite directions, thereby significantly increasing the mixing and stirring ability and achieving rotational composition. This offsets the need for centrifugal separation due to rotation, and the large number of through holes 2' and 3' sufficiently shear the liquid, making it easy to form fine particles on the micron scale. It is possible to obtain the excellent effect of being able to mix two or more types of liquids into micron-sized particles completely and in a short time without adding any additives such as emulsifiers. Furthermore, in the second invention, the liquid remaining on the outside of the inner circumferential wall of the container 1, which has been centrifuged or separated by specific gravity due to some remaining rotation, is returned to the center inside the container 1 by the centripetal flow generating blades 4. This system prevents liquid separation and immiscibility from occurring, and forcibly transitions to the mixing process of mixing agitation and collision shear using the rotating blades 3 and fixed partition walls 2. Therefore, water and water can be mixed in a short time of about 1 minute. Oil etc., light liquid,
The heavy liquid can be completely miscible, and there is no need to add any emulsifier, and an excellent effect can be obtained in that the mixture can be completely and quickly mixed.
