DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary fluid mixing device.

[0002]

2. Description of the Related Art Conventionally, as this type of mixing apparatus, Japanese Patent Application Laid-Open No. Sho 58-133822 is known. Such a mixing apparatus has a cylindrical casing having an inlet and an outlet at both ends, and is opposed to each other. A plurality of large and small discs in which a large number of small polygonal chambers each having an open front are arranged in a honeycomb shape on the surface to be concentrically superimposed, and the large-diameter disc is a casing. It has a diameter that matches the inner diameter, and has a through hole at the center, and the large-diameter disk and the small-diameter disk are shifted in position so that each of the small chambers communicates with a plurality of opposing small chambers. The plurality of flow guide units are arranged in a casing in such a manner that disks having the same diameter are adjacent to each other and arranged in the casing, and the large-diameter disks of the flow guide units are positioned on both sides. And let the communicating hole communicate with the inlet and outlet of the casing. That.

[0003] When the fluid to be mixed is pressurized and flows into the internal space of the casing from the inlet, the fluid reaches the inside from the flow hole of the upstream flow guiding unit, and the straight path is obstructed by the small diameter disk. The fluid flowing radially from the central portion to the outside through the small chambers communicating with each other and further reaching the inner peripheral surface of the casing after passing through the upstream flow guiding unit is moved inside the casing. From the flow path formed by the peripheral surface and the small diameter disk, enter each small chamber of the downstream flow guiding unit, flow into the central part, again enter the downstream flow guiding unit from the flow hole, and After passing through the small chambers again, the inside of the flow guiding unit flows sequentially from the center to the outside, and is finally discharged from the outlet.

However, since the sealing function is provided so that the outer diameter of the large-diameter disk is brought into close contact with the inner diameter of the casing, the processing accuracy of the inner diameter of the casing and the processing of the outer diameter of the large-diameter disk are provided. The precision must be precise, and in particular, the casing requires a length for arranging a plurality of flow guide units, so that it becomes difficult to precisely process the inner diameter over the entire length of the casing, and The outer diameter of the large-diameter disk is merely in close contact with the inner diameter of the casing. For this reason, when the supply pressure of the fluid increases, the inner diameter of the large-diameter disk increases due to distortion of the casing. If a slight gap is generated even partially between the diameter and the inner diameter of the casing, the gap leaks, and the fluid flows along the entire length of the inner peripheral surface of the casing to the outlet side in a short-circuit without receiving the mixing action. End up It has the disadvantage that first mixing ability is reduced.

In addition, the flow guiding unit has two large and small discs overlapped with each other by bringing the end faces on the opening side of the small chamber into contact with each other.
Due to the arrangement of multiple conducting units overlaid,
If the close contact between the end faces is not good and there is a small gap (a non-close place), the fluid leaks from this gap, and the fluid does not receive the mixing action without passing through the small chambers and short-circuits to the outlet side. It has the same drawbacks as above that flow.

In addition, the processing accuracy of the end face of the small chamber (surface unevenness, flatness, etc.) and the processing accuracy of the rear surface of each disk (surface unevenness, flatness, etc.) are precisely processed to obtain a surface. It is conceivable that the above-mentioned disadvantages can be solved by establishing a good close contact with each other, but the more precise the processing accuracy, the more the cost will increase significantly. In order to arrange a plurality of flow unit bodies, processing tolerances when precision processing is inevitably accumulated, and it is a reality that a small gap is generated at a close place on the end face of the small chamber,
Means for simply and inexpensively preventing these disadvantages are desired.

[0007]

A cylindrical body 10 is formed with the outer diameter determined, and flange pieces 11 and 11a are integrally formed inward from both ends of the cylindrical body 10 to form a ring seal body 8 having an outer diameter of the ring seal body. A circulation hole 15 is formed in the center of a disk 14 having a diameter larger than the inner peripheral diameter of the flange pieces 11 and 11a of FIG. 8, and cylindrical small chambers 16 and 16 open frontward from the front of the disk 14.
a ... the first mixing chamber group 17 in which a large number of
Further, the same small chamber as above from the distal end face of the first mixing chamber group 17
A second mixing chamber group 19 in which a large number of 16, 16a are arranged is integrally formed, and the chambers 16, 16a of the second mixing chamber group 19 and the chambers 16, 16a of the first mixing chamber group 17 are mutually connected. Komuro 16, 16a
Are arranged in a different position so as to communicate with the other small chambers 16, 16 a opposed to each other to form mixing elements 12, 12 a. The mixing element bodies 12 and 12a are arranged so that
Sealing members 23 and 23a made of an elastic body are provided between the distal end faces of the second mixing small chamber group 19 of the second mixing small chamber group 19 at locations where they contact with the front end face, and cover the distal opening portions of the second mixing small chamber group 19, In addition, a sealing element body 13 forming a flow passage 21 is provided on the inner peripheral surface side of the annular sealing body 8 to form a mixing and collecting element 5, and a desired number of the mixing and collecting elements 5 are arranged in the casing 4 and mixed. Since the flange pieces 11 and 11a of the annular sealing body 8 and the sealing bodies 23 and 23a of the sealing element body 13 in the collective element 5 are sandwiched by the lids at both ends of the casing 4 so as to be elastically deformed, the first mixed small chamber group 17 is formed. And the second mixing small chamber group 19 are integrally formed on the disk 14, so that there is no leakage from the gap between the small chambers 16, 16a... Close contact with the seals 23 and 23a 23, 23
a has a combined elastic restoring force due to the fluid pressure at the time of mixing the fluid, so that the tip opening side of the second mixing chamber group 19 is reliably fluid-tight. In this manner, leakage from such a location can be reliably prevented, and the flange pieces 11 and 11a of the ring seal body 8 are in close contact with the outer peripheral side of the rear surface of the disk 14 in an elastically deformed state. A sealing function is provided, whereby a leak from the rear surface of the disk 14 into the annular sealing body 8, a gap between the outer peripheral surface of the annular sealing body 8 and the inner peripheral surface of the casing 4 from the close contact point between the flange pieces 11 and 11 a. The mixing element bodies 12 and 12a can be prevented from being short-circuited due to leaks, and the mixing element bodies 12 and 12a are sandwiched and fixed by the flange pieces 11 and 11a and the seal bodies 23 and 23a of the seal element body 13. Since the rear surface of the second mixing chamber group 19 and the front end surface only contact the elastic body, The processing accuracy at the location does not require the precision as in the past, so that the processing cost can be reduced and the pulsation generated when the fluid passes through the mixing element 9 while flowing in a complicated manner, Even if the mixing element 9 vibrates due to the pulsation of the pump itself, the annular sealing body 8 and the sealing element body 13 function as a cushioning material against such vibration, and the vibration can be absorbed or attenuated. And adverse effects on the structure can be prevented.

Further, the mixing element 9 is connected to the ring seal body 8.
Of the casing 4 in the state of the mixed collecting element 5
In addition, since the large-diameter disks 14 are provided on both sides of the mixed collecting element 5 at the time of the interior, the casing 4 can be installed regardless of the direction with respect to the flow direction.
Since the interior of the casing 4 can be easily assembled, the sealing function does not have to be provided between the outer periphery of the annular seal body 8 and the inner periphery of the casing 4, so that the processing accuracy of the inner peripheral surface of the casing 4 can be roughened. In addition, it is easy to process the casing 4 in which a large number of the mixed collecting elements 5 are provided, and the cost can be reduced.

A gasket body 29 for elastically deforming the outer surfaces of the flange pieces 11 and 11a of the annular sealing body 8 in the desired number of mixed and assembled elements 5 in the casing 4 when the lids 7 and 7a are mounted. Since the outer surfaces of the flange pieces 11 and 11a are further pressed by the gasket body 29, the non-close contact portions between the flange pieces 11 and 11a and the outer peripheral side of the rear surface of the disk 14 are eliminated. The inner peripheral side of 11a can be prevented from being turned up, the sealing function at such a location can be improved, and mixing defects due to short-circuit flow can be further improved.

Also, in the inside of the flanges 11 and 11a of the ring seal body 8 and the flange pieces of the ring seal body 8 in the desired number of the mixed collecting elements 5 arranged in the casing 4.
A gasket body 29 having a communication hole 34 formed in the center is provided on the outer surface side of 11, 11a.
Since the flange pieces 11 and 11a are elastically deformed, in addition to the above-described effects, the area between the periphery of the circulation hole 15 on the rear surface of the disk 14 and the portion closely contacted by the flange pieces 11 and 11a of the annular sealing body 8 is added. A sealing function can be imparted, and mixing defects due to short-circuit flow at such locations are further improved.

Further, the seal body 2 in the seal element body 13
Since the shape of 3, 23a is formed in a mesh sheet shape so as to be in contact with the front end face of the second mixing chamber group 19 of the mixing element bodies 12, 12a,. In addition to the elastic deformation force caused by the holding force of 7a, when the fluid is mixed, the elastic pressure is further applied by the fluid pressure acting on each side surface 27 of each opening of the mesh-sheet-shaped seal members 23, 23a. Therefore, the sealing force of the distal end surface of the second mixing chamber group 19 of the sealing bodies 23, 23a and the mixing element bodies 12, 12a... By the elastic restoring force increases, and the sealing function is improved.

Further, the seal body 2 in the seal element body 13
3, 23a, the second mixing chamber group 19 of the mixing element bodies 12, 12a.
Formed with a fitting groove 28 into which the tip side of
Since the sealing element body 13 and the mixing element bodies 12, 12a... Are integrated by the fitting action between the tip end of the second mixing chamber group 19 and the second mixing chamber group 19, the displacement of the sealing element body 13 is regulated. The closed state of the openings of the mixing element bodies 12, 12a... Is always maintained to be fluid-tight, mixing failure due to leakage can be prevented, and the fluid pressure is reduced by the sealing bodies 23, 23a in the same manner as described above.
When the side surface 28b of the fitting groove 28 is elastically deformed and comes into close contact with the side wall 18a of the second small mixing chamber group 19, a sealing function is given to such a portion, and the sealing area is enlarged by expanding the sealing area. And the practical effect is extremely large.
