Japanese Patent Laying-Open No. 2003-190752 (paragraph [0003], FIG. 11)

In the emulsification dispersion apparatus described in Patent Document 1, since the fluid to be processed passes through the emulsification processing path formed between the valve side protrusion and the sheet side groove, the valve side protrusion and the sheet side groove are emulsified. The fluid to be processed collides with the part. However, since the valve-side protrusion has a triangular cross-sectional shape, the tip of the valve-side protrusion is a corner, and the tip of the valve-side protrusion is caused by a collision with the fluid to be processed. There is a possibility of missing as a lump.
Further, even in the emulsification dispersion apparatus provided with the net shown in FIG. 5, there is a possibility that a part of the net may be lost due to collision with the fluid to be processed, and even in the emulsification dispersion apparatus provided with the dimple part shown in FIG. 6, There is a possibility that a part of the concave portion on the valve side is missing.

  As described above, not only the emulsification dispersion apparatus described in the above-mentioned Patent Document 1, but also the emulsification dispersion apparatus provided with the net shown in FIG. 5 and the dimple portion shown in FIG. 6, there is a possibility that a part of the disk valve is missing. There is a risk that a part of the disk valve that is lacking may be mixed into the fluid to be treated as foreign matter.

  Recently, as the contaminants mixed into the fluid to be treated, those having strong wear properties such as calcium and cocoa powder have been used. In order to emulsify the fluid to be treated in which such contaminants are mixed, the pressure of the fluid to be treated introduced into the homogeneous disk mechanism needs to be high (for example, 30 to 150 MPa). Therefore, when the pressure of the fluid to be processed is set to a high pressure, the tip of the valve side protrusion is likely to be lost due to a collision with the high pressure fluid to be processed. There is a need to prevent.

  The present invention has been made paying attention to such points, and an object of the present invention is to provide an emulsifying and dispersing apparatus capable of preventing a part of a disk valve from being lost and preventing foreign matters from being mixed into a fluid to be treated. It is in.

In order to achieve this object, a characteristic configuration of an emulsifying dispersion device according to the present invention includes a disk valve and a seat provided to face the disk valve, and the radial direction is provided between the disk valve and the seat. In the emulsification dispersion apparatus for emulsifying the fluid to be processed by passing the fluid to be processed through the emulsification processing path formed in
On the surface of the disc valve facing the seat, a ring-shaped valve side projection is provided around the axis, and on the surface of the seat facing the disc valve, a seat side groove which is assembled to the valve side projection The valve-side protrusion is formed such that the distal end side is formed narrower than the proximal end side, and the distal end portion is configured in a planar shape facing the emulsification processing path.

According to this characteristic configuration, the valve side protrusion is formed so that the distal end side is narrower than the base end side, and therefore, the covered side that passes through the emulsification processing path formed between the valve side protrusion and the seat side groove is formed. The processing fluid collides with the valve side protrusion and the seat side groove, so that the fluid to be processed can be accurately emulsified and dispersed. Moreover, since the tip of the valve-side protrusion is a surface facing the emulsification processing path, for example, a flat surface along the radial direction of the disk valve or an inclined surface protruding toward the outer diameter side of the disk valve in the radial direction. The tip portion has no pointed portion and can be prevented from being lost due to collision with the fluid to be processed.
From the above, it is possible to realize an emulsification and dispersion apparatus that can emulsify and disperse the fluid to be treated, while preventing a part of the disk valve from being lost and preventing foreign matters from entering the fluid to be treated.

  In the emulsifying and dispersing apparatus according to the present invention, the valve-side protrusion is formed to be narrower toward the tip side, and the seat-side groove is formed to be narrower as the depth is deeper. In the point.

  According to this characteristic configuration, a linear flow channel that is inclined with respect to the radial direction is formed as an emulsification treatment path by the valve side protrusion portion that is narrower toward the tip side and the sheet side groove portion that is narrower as the depth is deeper. can do. Thereby, the fluid to be processed can be accurately emulsified and dispersed by passing the fluid to be processed through the emulsification processing path inclined with respect to the radial direction.

  A further characteristic configuration of the emulsification dispersion device according to the present invention is that a plurality of the valve-side protrusions are provided in a state of being arranged in the radial direction of the disk valve, and the emulsification is performed at each of the tip ends of the plurality of valve-side protrusions. The surface facing the processing path is configured such that the area on the inner diameter side in the radial direction of the disk valve is larger.

  Since the fluid to be processed flows from the inner diameter side toward the outer diameter side through the emulsification processing path extending in the radial direction, the more the valve side protrusions arranged in the radial direction, the more the one located on the inner diameter side, It will collide with the high-pressure fluid to be treated. Therefore, according to the present characteristic configuration, the surface facing the emulsification treatment path in each of the plurality of valve side protrusions is increased in area on the inner diameter side in the radial direction of the disk valve. It can prevent exactly that the front-end | tip part of is missing. In addition, the surface facing the emulsification processing path in each of the plurality of valve side protrusions has a smaller area on the outer diameter side in the radial direction of the disk valve, so the collision between the fluid to be processed and the valve side protrusions etc. And the emulsified dispersion state of the fluid to be treated can be kept accurate.

  A further characteristic configuration of the emulsifying and dispersing apparatus according to the present invention is that a plurality of the valve-side protrusions are provided in a state of being aligned in the radial direction of the disk valve, and each of the plurality of valve-side protrusions is provided on the disk valve. In the radial direction, the height of the inner diameter side is lower.

  As described above, among the plurality of valve side protrusions arranged in the radial direction, the one located on the inner diameter side collides with a higher pressure fluid to be processed. Therefore, as in this feature configuration, by reducing the height of each of the plurality of valve side protrusions toward the inner diameter side in the radial direction of the disk valve, the tip of the valve side protrusion is missing. In addition, it is possible to accurately prevent an emulsified dispersion state of the fluid to be treated by causing the valve-side protrusion having a high outer diameter in the radial direction to collide with the fluid to be treated. Can do.

  A further characteristic configuration of the emulsification dispersion apparatus according to the present invention is that the axial width of the emulsification processing path is configured to increase toward the inner diameter side in the radial direction of the disk valve.

  As described above, the fluid to be treated flows from the inner diameter side toward the outer diameter side through the emulsification treatment path extending in the radial direction. Will do. As in this feature configuration, by increasing the axial width of the emulsification processing path toward the inner diameter side in the radial direction of the disk valve, a part of the disk valve on the inner diameter side of the emulsification processing path is missing. While accurately preventing, the emulsified dispersion state of the fluid to be treated can be kept accurate. For example, in the case where a plurality of valve side protrusions are provided in a state of being arranged in the radial direction, the height of the plurality of valve side protrusions arranged in the radial direction that is located on the inner diameter side in the radial direction is lowered. For example, the width in the axial direction of the emulsification processing path can be increased toward the inner diameter side in the radial direction. In addition, in one valve side protrusion, the surface facing the emulsification processing path at the tip is an inclined surface that protrudes toward the outer diameter side in the radial direction, so that the axial width of the emulsification processing path is radial. The inner diameter side can be increased.

  According to a further characteristic configuration of the emulsifying and dispersing apparatus according to the present invention, the surface of the seat facing the disc valve is provided with a ring-shaped seat side protrusion around the axis, and the disc valve facing the seat A valve-side groove that is assembled to the seat-side protrusion is provided on the surface of the sheet-side protrusion, and the front-end side of the seat-side protrusion is formed to be narrower than the base end side, and the front-end portion faces the emulsification treatment path The point is that it is configured in a planar shape.

  According to this characteristic configuration, by providing the sheet side protrusion not only on the disc valve side but also on the seat side, the fluid to be processed can collide with the sheet side protrusion, and the emulsified dispersion state is improved. Can be achieved. In addition, the seat-side protruding portion, like the valve-side protruding portion, has a planar shape that faces the emulsification treatment path, so that the tip of the seat-side protruding portion can be prevented from being chipped. , Foreign matter can be prevented from being mixed into the fluid to be treated.

  A further characteristic configuration of the emulsification dispersion device according to the present invention is that the surface shape facing the emulsification processing path is configured as a flat surface shape along the radial direction of the disk valve.

  According to this characteristic configuration, the tip of the valve-side protrusion is a flat surface along the radial direction of the disk valve, thereby forming a surface facing the emulsification processing path. As a result, the tip of the valve-side protrusion need only be processed flat along the radial direction of the disk valve, and it will be lost due to collision with the fluid to be processed simply by performing such simple processing. Can be prevented.

[Second Embodiment]
This 2nd Embodiment shows another embodiment of the valve | bulb side protrusion part 20 in the said 1st Embodiment. Hereinafter, the valve-side protrusion 20 in the second embodiment will be described with reference to FIG. 4, but the other configurations are the same as those in the first embodiment, and thus description thereof will be omitted.

The flat surface 18a in each of the plurality of bulb-side protrusions 18 has a larger radial area on the inner diameter side (the lower side in FIG. 4) in the radial direction so that the area on the inner diameter side in the radial direction becomes larger. The width is configured to be large. That is, the surface width of the flat surface 18a of the valve-side protrusion 18 positioned on the outermost diameter side is D, and the surface width of the flat surface 18a of the valve-side protrusion 18 positioned next to the inner diameter side is D1, where The surface width of the flat surface 18a of the valve-side protrusion 18 positioned on the side is D2, and D2>D1> D.

By making the height lower on the inner diameter side (lower side in FIG. 4) in the radial direction, it is possible to accurately prevent the tip of the valve side protrusion 18 from being chipped. Moreover, since the width in the axial direction of the emulsification processing path 11 is smaller toward the outer side in the radial direction (upper side in FIG. 4), synergistic effects such as shearing and collision between the particle molecules of the fluid L to be processed are achieved. It can be generated accurately and a homogeneous emulsified state can be created.

  In the second embodiment, the seat-side protrusion 20 is the same as in the first embodiment, but the flat surface 20a of each of the plurality of seat-side protrusions 20 has a diameter similar to that of the valve-side protrusion 18. It can be configured such that the area on the inner diameter side (lower side in FIG. 4) increases in the direction, and the surface width in the radial direction increases on the inner diameter side in the radial direction. Each of the plurality of sheet-side protrusions 20 may be configured such that the height of the sheet-side protrusion 20 on the inner diameter side (the lower side in FIG. 4) decreases in the radial direction.

[Third Embodiment]
In the said 1st and 2nd embodiment, although the front-end | tip part of the valve | bulb side protrusion part 18 is made into the flat surface shape which has the flat surface 18a along radial direction, it is set as the surface shape which faces the emulsification process path 11, but is flat. Instead of the surface, for example, a surface shape facing the emulsification processing path 11 can be obtained by forming an inclined surface shape having an inclined surface protruding toward the outer diameter side in the radial direction. By providing such an inclined surface, the width in the axial direction of the emulsification processing path 11 can be configured to increase toward the inner diameter side in the radial direction of the disk valve 8. Therefore, collision between the fluid to be treated and the valve-side protrusion 18 on the outer diameter side of the tip of the valve-side protrusion 18 while accurately preventing chipping on the inner-diameter side of the tip of the valve-side protrusion 18 is achieved. And the emulsified dispersion state of the fluid L to be treated can be kept accurate.
