Description

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, there has been known a stationary mixing device having no mechanically movable portion, as disclosed in Japanese Patent Publication No. 59-39173. Such a mixing device has a cylindrical shape having an inlet and an outlet at both ends. And a plurality of flow guide units formed by concentrically superimposing two large and small disks in which a large number of polygonal small chambers each having an open front face are arranged in a honeycomb shape on surfaces facing each other. The large disk has a diameter matching the inner diameter of the casing, and a circulation hole is formed in the center, and the large-diameter disk and the small-diameter disk communicate with other small chambers in which the small chambers face each other. The plurality of flow guide units are arranged in a casing in such a manner that discs having the same diameter are adjacent to each other and arranged in the casing, and the size of the flow guide units is large on both sides. A circular disk and place its communication hole in the casing inlet. And communicates with the fine outlet.

[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.

[0004]

However, since the sealing function is provided so that the outer diameter of the large-diameter disk coincides with the inner diameter of the casing, the processing accuracy of the inner diameter of the casing and the large-diameter circular disk are provided. It is necessary to make the processing accuracy of the outer diameter of the plate precise, and in particular, since the casing needs a length for arranging a plurality of flow guiding units, over the entire length of the casing,
It is difficult to precisely process the inner diameter, and the outer diameter of the large disk is merely in contact with the inner diameter of the casing. If the inner diameter expands due to distortion, and even a small gap occurs even partially between the outer diameter of this large disk and the inner diameter of the casing, the fluid flows along the entire length of the inner circumferential surface of the casing from this gap. Has a problem that the original uniform mixing ability is reduced due to the short-circuit flow to the outlet side without receiving the mixing action.

[0005] In addition, the flow guiding unit is configured such that two large and small disks are overlapped by bringing the end faces on the opening side of the small chamber into contact with each other, and a plurality of flow guiding units are arranged in an overlapping manner. However, the close contact state between the end faces is not good, and a slight gap is generated, and the fluid flows through this gap to the outlet side in a short-circuited manner without receiving the mixing action. have.

Further, the processing accuracy of the end face of the small chamber (surface unevenness, flatness, etc.) and the processing accuracy of the back surface of each disk (the surface unevenness, flatness, etc.) are precisely processed to obtain the end face. It seems that it is possible to solve the above problem by making the close contact state good, but as the processing accuracy becomes more precise, the cost rises significantly, and there is a limit to the precision of the processing accuracy. At the same time, in order to arrange a plurality of flow guide units, the processing tolerance when precision processing is inevitably accumulated, and it is a reality that a slight gap is generated at the contact portion of the end face of the small chamber, There is a need for a means for simply and inexpensively preventing the above problems.

It is set smaller than the thickness T2.

On the outer end side of the mixed collecting element 5 disposed on both sides in the casing 4, the thickness T of the small-diameter spacer 26 as the compression deformation restricting means 24 is naturally
Numeral 1 is set smaller than the thickness T of the flange pieces 12 and 12a in order to provide the same function as described above.
The cover 26 may be fixedly provided on the lids 7 and 7a (either separately or integrally).

As another embodiment of the compression deformation restricting means 24, as shown in FIGS. 19 to 22, between the mixed collecting elements 5 disposed inside the casing 4 and outside the mixed collecting elements 5 on both sides. A large-diameter spacer 28 is provided on the end side.

Next, the operation of the stationary type fluid mixing device according to the present invention is as follows.
, The tight contact between the upper end faces of the side walls 14 forming the small chambers 15, 15 a in the disks 16, 17 can be maintained firmly, and the flange pieces 12,
Since 12a is closely contacted with the back surface on the outer peripheral side of the large-diameter disk 16 in an elastically compressed and deformed state, a sealing function is provided at such a location. And the leakage between the outer peripheral surface of the annular sealing body 9 and the inner peripheral surface of the casing 4 from the close contact between the flange pieces 12 and 12a can be restricted.

When the compression deformation restricting means 24 is provided, the mixed collecting element 5
The number of the seals 9 in the mixed collecting element 5 increases as the number of the seals 9 increases, and as the material approaches the center of the casing 4 due to the material of the seals 9 and the clamping (pressing) force of the lids 7 and 7a. It is possible to prevent the elastic pieces from being elastically compressed and deformed until the flange pieces 12 and 12a exhibit the sealing function. Specifically, the compression deformation restricting means 24 provided on the back surface of the large-diameter disk 16 is used.
The step size L4 of the step portion 25 as a part is made smaller than the thickness T of the flange pieces 12 and 12a, and the thickness T1 of the small diameter spacer 26 as the compression deformation restricting means 24 is made the thickness T of the flange pieces 12 and 12a.
2. It can be made smaller than the wall thickness T,
By making the step size L4 of the step 25 of the large diameter spacer 28 smaller than the thickness T of the flange pieces 12 and 12a, the flange pieces 12 and 12a of the ring seal body 9 are mixed by the lids 7 and 7a. When the collective element 5 is elastically compressed and deformed until the desired sealing function is exerted when the collective element 5 is clamped and fixed, the lid 7,
The large-diameter disks 16 formed of a material that does not substantially deform in the thickness direction even by the pinching (pressing) force at 7a come into contact with each other, or the large-diameter disks 16 contact both surfaces of the small-diameter spacer 26. Since the large-diameter disc 16 comes into contact with both surfaces of the large-diameter spacer 28 or the like, the amount of elastic compressive deformation of the flange pieces 12 and 12a is restricted to a certain amount or less. Pinching (pressing)
The force is applied to the disk 16, the small-diameter spacer 26, the large-diameter spacer
A collar piece 12 of the ring seal body 9 located on the center side through 28;
12a is also transmitted uniformly without reducing the pinching (pressing) force.

Next, the basic mixing action of the static fluid mixing device according to the present invention is as follows. When a fluid is pressurized and flows into the internal space of the casing 4 from the inlet 2 of the static fluid mixing device 1, For example, as shown by an arrow shown in FIG. 1, the flow from the mixing element 10 on the upstream side reaches the inside from the flow hole 18, the straight path is obstructed by the small-diameter disc 17, the direction changes, and a plurality of communicating with each other. From the central part to the outside through the small chambers 15 and 15a ...
The state of dispersion, merging, meandering, eddy current, etc. is combined and flows in a complicated manner.

As described above, the fluid that has passed through the mixing element 10 on the upstream side and reached the inner peripheral surface of the annular seal body 9 flows through the flow passage 19 formed on the inner peripheral side of the annular seal body 9. .. Enter the small chambers 15, 15a,... Of the downstream mixing element 10, and are gathered in the central part by a complicated flow such as the above-mentioned right angle collision, dispersion, confluence, meandering, vortex, and the like. Entering the mixing element 10 and then again passing through the small chambers 15, 15a... From the center to the outside at right angle collision, dispersion, confluence, meandering, vortex, etc.
It flows inside 10 and is discharged from outlet 3.

As described above, the fluid impinges on the side walls 14 of the disks 16, 17 and the small chambers 15, 15a at right angles, and the small chambers 15, 15a.
Distributed from… to several other compartments 15, 15a…, several compartments
Merging, meandering from 15, 15a… to another chamber 15, 15a… and from several chambers 15, 15a… to each chamber 15, 15a…
Shear due to eddy current due to inflow into the chamber, each chamber 1
Hydrodynamic shearing when passing through the orifice, which is a communication path from 5, 15a ... to other small chambers 15, 15a ..., crushing by impact breaking, shearing when passing through the end face of small chamber 15, 15a ... The fluid is uniformly dispersed and mixed by mechanical cavitation or the like.

The total number of dispersions of the mixing elements 10 in the mixing collecting element 5 (the number of dispersions when the fluid passes) is determined by the small chambers 15 of the two large and small disks 16, 17 arranged radially sequentially from the center. 15a... For example, in the case of a hexagonal shape in plan view shown in FIG. 8, three rows of circles having six, twelve, and eighteen rooms (a total of 36 rooms) are provided. The board 16 and the number of rooms are 3, 9, and 15 (27 in total)
When the three rows of circular plates 17 of the chambers are superposed, the total number of dispersions reaches several thousands even with one fluid.

[0042]

In short, since the present invention is constructed as described above, the mixing element 10 can be housed in the casing 4 in the state of the mixing / collecting element 5 which is housed in the ring seal body 9, and the mixing / assembly can be performed at the time of such housing. Element 5
Since the large-diameter discs 16 are provided on both sides of the casing 4, the casing 4 can be installed irrespective of the direction of the flow direction. Since it is not necessary to provide a sealing function between the inner circumferences, the processing accuracy of the inner circumferential surface of the casing 4 can be roughened, so that the processing of the casing 4 containing a large number of the mixed collecting elements 5 can be easily performed, and the cost can be reduced. Also, since the mixing element 10 is sandwiched and fixed by an elastic body, even when the mixing element 10 oscillates due to pulsation generated when the fluid passes while mixing inside the mixing element 10 while flowing complicatedly, Since the annular sealing body 9 functions as a cushioning material and can absorb or attenuate vibration, it is possible to prevent adverse effects on peripheral devices and structures. .

Further, since the mixed collecting element 5 can be sandwiched and fixed by the lids 7 and 7a, the close contact between the upper end surfaces of the side walls 14 forming the small chambers 15, 15a.
Since the flange pieces 12 and 12a of the annular sealing body 9 are tightly sealed to the back surface on the outer peripheral side of the large-diameter disk 16, short-circuit flow from such locations is regulated, and poor mixing is prevented. Can be prevented.

The flange pieces 12, 12 of the ring seal 9 in all the mixed collecting elements 5 provided in the casing 4.
a can be reduced to a certain amount or less.
The sealing force at the sealing point between 2, 12a and the large-diameter disk 16 is
The mixing / collecting element 5 arranged at the center of the casing 4 can be reliably secured, and a uniform sealing force can be obtained.
As a result, it is possible to prevent a problem that the flange pieces 12 and 12a cannot exert the sealing function.
Does not occur from the sealing portion, and a reduction in the original uniform mixing ability can be prevented.

Also, a step portion as the compression deformation restricting means 24
25 is provided on the outer peripheral surface side of the large-diameter disc 16, if there is a dimensional difference in the inner diameter of the flange pieces 12, 12 a that are in close contact with each other, and if the step portion 25 is not formed, The inner peripheral edges of the pieces 12 and 12a are not pressed, and non-close parts are formed. The flange pieces 12 and 12a at such places may be turned up, resulting in poor sealing. Step as
Since 25 is provided on the outer peripheral surface side of the large-diameter disk 16 and the large-diameter spacer 28, the entire surface of the flange pieces 12 and 12a can be surely pressed by the step portion 25. The rising phenomenon can be prevented, and the sealing function at such a location is maintained, so that the original uniform mixing ability can be prevented from lowering.

Further, since the small-diameter spacer 26 and the large-diameter spacer 28 are provided as the compression-deformation restricting means 24, in addition to the same effects as described above, the dead space is caused by eliminating the dead space. Its practical effect is remarkable, such as poor mixing.
