DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid mixing apparatus for uniformly mixing the viscosity, material, color, etc. of a fluid.

[0002]

2. Description of the Related Art Conventionally, in extrusion molding of resin, rubber, etc.,
In order to improve the quality of the molded product by uniformly mixing the viscosity, material, color tone, etc. of the material supplied from the extruder to the die,
For example, Japanese Utility Model Publication No. 61-21216, Tokiko 1-3
The fluid mixing device disclosed in Japanese Patent No. 9815 or the like is widely used.

FIG. 11 shows a fluid mixing apparatus of this type, in which a plurality of spiral elements 3 are arranged in a through hole 1a of a cylinder tube 1 in the axial direction. These spiral elements 3 are formed in a plate shape twisted 180 degrees in the axial length direction of the cylinder tube 1 and are arranged alternately so that the twist directions are reversed. In this fluid mixing device, the material that has flowed into the through hole 1a of the cylinder tube 1 moves in the through hole 1a in a direction through the torsion of the spiral element 3 formed in a plate shape that bisects the through hole 1a in the axial direction. Rotating and flowing while changing.

[0004] The material is a through hole 1a of the cylinder tube 1.
The materials are agitated and mixed while passing through.

[0005]

However, in the above-described fluid mixing apparatus, the materials are rotated and stirred while changing the rotation direction by the spiral elements 3 alternately arranged so that the twist directions are reversed. When a high-viscosity fluid such as resin or rubber is to be mixed, there is a problem that the viscosity of the fluid itself is not sufficient, and it is difficult to make the viscosity, material, color tone, etc. of the fluid uniform.

[0006] That is, due to unevenness of the viscosity, material, color tone, etc. of the fluid, there is a problem that molding failure such as uneven thickness, sink, weld, etc. occurs in the molded product, and the production yield of the molded product cannot be improved. Was. Further, since the material is mixed by the spiral element 3 which bisects the through hole 1a of the cylinder tube 1 in the axial direction, when the fluid having a high viscosity is mixed, the fluid is divided in the axial direction of the through hole 1a. And
There is a problem that streak-like uneven mixing in the flow direction occurs.

Further, since the fluid is agitated by the rotational flow due to the twist of the spiral element 3, it is necessary to arrange a number of spiral elements 3 in order to sufficiently mix the fluid, and the axial length of the cylinder tube 1 is reduced. There is a problem that the device becomes longer and the device becomes larger. In addition, since the axial length of the cylinder tube 1 is increased in order to increase the mixing efficiency of the fluid, there is a problem that the heating time of the fluid by the heater is increased and the fluid is thermally degraded.

Further, since the axial length of the cylinder tube 1 becomes longer and the volume of the through hole 1a becomes larger, there is a problem that the pressure loss becomes larger and the capacity of the pump for pumping the fluid must be increased. . Further, since the plate-like spiral elements 3 which are twisted by 180 degrees in the axial direction of the cylinder tube 1 are alternately arranged so that the twisting directions are reversed, the structure of the device becomes complicated, and a great amount of labor and labor are required for manufacturing. There was a problem that it took time.

[0009] Further, in the axial direction of the cylinder tube 1, 180
The twisted plate-like spiral elements 3 are alternately arranged so that the twist direction is reversed, so that the internal structure of the device becomes complicated, and when changing the type of fluid to be mixed, or when a predetermined period has elapsed. There is a problem that the cleaning operation to disassemble the apparatus and clean the inside when it is performed becomes complicated.

The present invention has been made to solve such a conventional problem, and provides a fluid mixing apparatus which can surely mix a fluid and can greatly simplify the structure as compared with the conventional one. The purpose is to do.

The cylinder member 11 has a circular through hole 11a penetrating in the axial direction. The surface of the through hole 11a is mirror-finished with high precision by grinding such as homing after cutting. Annular flange portions 11b are integrally formed at outer edges of both ends of the cylinder member 11.

On the side surface of the flange 11b, a plurality of female screw holes 11c are formed concentrically with the through holes 11a. At both ends of the through hole 11a, a circular sleeve insertion hole 11d is formed with an increased diameter.

A cylindrical sleeve 13 made of a metal material is inserted into the sleeve insertion hole 11d. At an inner end of the inner peripheral surface of the sleeve 13, a tapered support member contact portion 13a is formed. An annular port member 15 made of a metal material is provided at the opening at both ends of the cylinder member 11.

A bolt insertion hole 15a is formed in a side surface of the port member 15 at a position corresponding to the position of the female screw hole 11c. A counterbore hole is formed on the opposite side of the bolt insertion hole 15a from the cylinder member 11 to have an enlarged diameter. An opening having an inner diameter smaller than the inner diameter of the sleeve 13 is formed at the center of the port member 15.

The through hole 11a side of this opening is formed in a tapered shape which spreads toward the cylinder member 11 side.
The diameter of this end is formed to be the same as the inner diameter of the sleeve 13. On the side surface of the port member 15 on the cylinder member 11 side, an annular convex portion 15d protruding laterally is integrally formed.

The outer dimensions of the projection 15d correspond to the inner diameter of the sleeve insertion hole 11d. The port member 15 is fixed to the flange portion 11b of the cylinder member 11 by fitting the projection 15d into the sleeve insertion hole 11d and screwing the bolt 17 into the female screw hole 11c.

In the cylinder member 11, six core members 19 made of an iron material are arranged on the central axis of the through hole 11a. The core member 19 is formed of a spherical bearing ball (corresponding to claims 4 , 5, and 7 ). On both sides of the core member 19 on the fluid inflow side and the fluid outflow side, a core support member 21 made of an iron material is disposed so as to sandwich the core member 19.

[0029] The core supporting member 21 is formed by spherical bearing ball (corresponding to claim 5 and 7) and is rotatable around the central axis of the through hole 11a (claim 1 Corresponding to).

The through-hole is dispersed and diffused from the tip of the spherical core member 19 supported on the central axis of the through-hole 11a of the cylinder member 11 to the inner wall side of the through-hole 11a along the outer peripheral surface. After being compressed by the peripheral surface and the outer peripheral surface of the core member 19, it is diffused again, dispersed through the outer gap and the inner gap of the outflow-side core support member 21, and The parts are integrated by the part 15c and discharged in a mixed state.

At this time, the core support member 21 rotates about the central axis of the through hole 11a due to a change in the viscosity of the fluid, and the flow path for dispersing the fluid changes irregularly.
