Description

  The present invention relates to a collision apparatus for emulsifying a fluid, atomizing particles in a fluid, and dispersing them by causing a high-pressure fluid to collide with a hard sphere.

  Conventionally, when emulsifying a raw material liquid or atomizing or dispersing a granular raw material substance in the liquid, the impact force generated by injecting the raw material liquid from the injection nozzle at a high pressure and causing the high-pressure jet to collide with a hard body is used. A collision device is used. As the hard body, a plate-shaped one was used, but since the high-pressure jet always collided with the same position, a hole was opened in the hard plate due to long-term operation, and frequent replacement is necessary, so stop There are many elements that increase running costs, such as time, labor, and members, and they are not suitable for practical use in the continuous production process of products.

  In view of this, there has been considered a collision device that has a long life by using a spherical hard body. This is because the hard sphere is rotatably supported at a position eccentric to the injection axis of the high-pressure jet in the collision chamber so that the high-pressure jet injected from the injection nozzle is incident on the surface of the hard sphere at the collision point. The hard sphere is caused to collide with the line at a tilt angle of less than 90 degrees to cause the hard sphere to rotate with a component of the collision force. Therefore, since the hard sphere always rotates while the high-pressure jet collides, the collision position on the surface of the sphere always changes, and the problem of drilling due to continuing collision at the same point is avoided ( For example, see Patent Document 1.)

JP 2000-448

  However, even in the collision device using the hard sphere supported in an eccentric position with respect to the injection axis as described above, the inclination angle at which the high-pressure jet collides with the hard sphere surface is constant, so the rotation direction of the hard sphere Since the collision is concentrated on the same circumference on the surface of the hard sphere, a groove-like damage occurs along the circumference during long-time operation.

  Therefore, although the life of the spherical hard body arranged in an eccentric position with respect to the injection axis is longer than that in the case of using a hard plate, it is still better due to the above groove-like damage in a long-time operation in accordance with practical use. Since the collision treatment cannot be maintained and the quality of the product is deteriorated, the hard sphere must be replaced, and sufficient efficiency cannot be expected in practical use of the product manufacturing process by the continuous collision treatment of the raw material liquid.

  In view of the above problems, an object of the present invention is to provide a collision apparatus that enables a longer hard sphere for collision than in the past and can improve the efficiency of a raw material liquid collision treatment process over a long period of time. is there.

In order to achieve the above object, a collision apparatus according to a first aspect of the present invention is a collision apparatus in which a high-pressure jet sprayed from an injection nozzle collides with a spherical hard body rotatably supported in a collision chamber. ,
Comprising a first injection nozzle and a second injection nozzle for injecting a fluid toward the hard body and causing the jets to collide with different positions on the surface of the hard body;
The injection axis of the first injection nozzle and the injection axis of the second injection nozzle are each directed to a position eccentric with respect to the spherical center of the hard body.

According to a second aspect of the present invention, there is provided a collision apparatus according to the first aspect, wherein the collision apparatus according to the first aspect includes a fluid supply means for performing pressurized supply of fluid to the first injection nozzle and the second injection nozzle. ,
Control for arbitrarily controlling supply and stop of the fluid to the first and second spray nozzles by the fluid supply means, and controlling the pressure applied to the fluid supplied to each spray nozzle to be changeable. Means.

  Furthermore, the collision apparatus according to the invention described in claim 3 is the collision apparatus according to claim 2, wherein the injection axis of the second injection nozzle is orthogonal to the injection axis of the first injection nozzle. It is characterized by being on a plane.

  In the collision device according to the present invention, a high-pressure jet is caused to collide with a spherical hard body, and the injection axes are directed to positions eccentric from the spherical center of the spherical hard body, and are different from each other on the surface of the hard body. Since the first injection nozzle and the second injection nozzle that cause the jet to collide with the position are provided, the first collision point where the jet from the first injection nozzle collides with the hard body and the second Rotational force due to the component force of the collision force is generated at each of the second collision points where the jet flow from the injection nozzle collides, and the rotation in the two different directions acts synergistically so that the collision target region is a hard body. Since it covers almost the entire surface, collisions do not concentrate at a specific location even during long-time operation, so there is no longer any significant damage. Good for long-term operation Continuous collision processing state can be maintained, even reduction of running costs there is an effect that can be expected.

  The present invention relates to a collision device that collides a high-pressure jet against a spherical hard body, and each jet axis is directed to a position eccentric to the spherical center of the spherical hard body, and the jets collide with different positions on the surface of the hard body. By providing the first injection nozzle and the second injection nozzle to be caused, the hard body has the first collision point where the jet flow from the first injection nozzle collides with the jet flow from the second injection nozzle. Since a rotational force is generated by a component of the collision force at each of the second collision points that collide, the rotation in two different directions acts synergistically while the jets collide, and the hard body surface Substantially moves relative to the two collision positions in various directions, and the collided portions are totally dispersed.

  Therefore, according to the present invention, the collision area extends over almost the entire surface of the hard body, and the collision does not concentrate at a specific location as in the prior art, causing significant damage, and the life of the hard body can be further extended. In addition, it is possible to maintain a good continuous collision treatment state even for a long time operation according to the actual product manufacturing process, and to expect a reduction in running cost.

  That is, in the present invention, the collision positions on the spherical hard body surface of the jets ejected from the first and second ejection nozzles are different from each other in the direction of the rotational force generated at each collision point. In other words, any position where the rotational force is generated in the rotational direction where the respective rotation center axes do not coincide with each other may be used.

  However, when the same collision force acts on the hard body by simultaneously injecting a high-pressure jet from both the first and second injection nozzles, there is a risk that the spherical hard body will not rotate satisfactorily due to the mutual collision force antagonizing. Therefore, if the injection from the first injection nozzle and the injection from the second injection nozzle are alternately switched, or if the collision force is different between the first and second injection nozzles, Due to the synergistic effect of rotation in two different directions, the surface collision location of the spherical hard body relative to the jet collision position is displaced relatively variously during the long collision process, and substantially over the entire surface. The collision parts will be dispersed.

  In order to inject the fluid so that the first injection nozzle and the second injection nozzle have different collision forces as described above, the nozzles having different flow rates are also used and the nozzles are injected from each nozzle. This can be realized by making the fluid pressures different from each other.

  Actually, in order to switch the fluid injection between the first injection nozzle and the second injection nozzle or to make the fluid pressures different from each other, the first injection nozzle and the second injection nozzle are added. For example, it can be performed by driving and controlling fluid supply means such as a pump device that supplies pressurized fluid.

  Therefore, the supply and stop of the fluid to the first injection nozzle and the second injection nozzle by the fluid supply means are arbitrarily controlled, and the pressure applied to the fluid supplied to each injection nozzle can be changed. If a control means is provided, a supply period and a stop period from the start of fluid supply to each injection nozzle according to a desired switching operation of the injection process, and a pressure applied to the fluid supplied to each injection nozzle are set in advance. In addition, if the setting is input to the control means as the operation command and the command is executed, the fluid supply means is controlled so that the collision processing operation can be easily performed so that a good hard body rotation state can be maintained. Can do.

  Note that when the first injection nozzle and the second injection nozzle have different collision forces, one of them has a weaker collision force than the other. Due to the difference in impact force, a difference occurs in the treatment state, and emulsification and atomization are difficult to be uniform. Therefore, the first injection nozzle is used for the collision treatment, the raw material liquid is injected at a high pressure that provides a collision force sufficient to obtain an impact sufficient for emulsification and atomization, and the second injection nozzle is exclusively formed on the spherical hard body. For example, if the medium solution of the raw material liquid is jetted for rotation to give a rotational force in a direction different from that caused by jet collision from the jet nozzle, the emulsification and atomization processing state itself is the first jet. Since it depends only on the jet collision from the nozzle, non-uniform processing can be avoided.

  When both the first injection nozzle and the second injection nozzle as described above are used for collision processing and simultaneously inject the same raw material liquid, the collision force increases as the eccentric amount becomes larger than the spherical center of the hard body. Since the bias toward the component force generated in the rotational force increases and the impact force decreases and the effect of emulsification and atomization is reduced, in order to efficiently perform collision processing with a certain impact force, both It is necessary to suppress the amount of eccentricity with respect to the spherical center in both of the injection nozzles, and as a result, collision positions relatively close to each other are desired. Therefore, if a configuration in which both injection nozzles are formed on the same member is incorporated in the collision device, the amount of eccentricity with respect to the spherical center can be kept small, and good collision processing can be performed. It is possible to design a simple device that supplies the two at the same time, and it is effective for downsizing the device with a small number of parts.

  On the other hand, when the first injection nozzle is used for collision processing and the second injection nozzle is used for rotation of a hard body, each injection nozzle is formed on a separate member and incorporated in the collision device. In addition, it is easy to separately provide a fluid introduction path and switch the raw material liquid and the medium liquid to each other at different pressures to control supply to the respective injection nozzles.

  In this way, when the first and second injection nozzles are formed as separate members and incorporated in different positions of the collision device, the first injection nozzle for collision processing is as hard as possible. The arrangement is such that the amount of eccentricity from the ball center is kept as small as possible to obtain an excellent collision treatment effect such as emulsification and atomization of the raw material liquid, and the second injection nozzle for rotation is a jet flow by the first injection nozzle Separate settings are facilitated without affecting each other so that the rotational position can be generated so that the collision position can be dispersed over a wider range on the surface of the hard body.

  For example, assuming that the second injection nozzle for rotation is on a plane whose injection axis is orthogonal to the injection axis of the first injection nozzle for collision processing, the injection axes of both injection nozzles are in a plane. Is set at an angle of 90 degrees, as a collision position of the rotating jet by the second injection nozzle, a large displacement of the collision area along the rotation direction by the jet collision of the first injection nozzle can be more efficiently performed. At the same time, it can be set at a remote position with little influence on the collision process of the high-pressure jet by the first injection nozzle.

  In addition, in this invention, it is not limited to the structure provided only with the 1st and 2nd injection nozzle, For example, it is good also as a structure further provided with the 3rd injection nozzle. In this case, if the jets of all nozzles are at different positions on the surface of the spherical hard body and the respective injection axes are eccentric from the center of the hard body, all the injection nozzles are set for collision processing. Alternatively, a combination of two for collision and one for rotation, or conversely, two for rotation and one for collision is possible. Of course, if the design is not difficult, it is possible to employ a configuration in which four or more injection nozzles are provided to make various combinations for collision and rotation.

  Hereinafter, as a first embodiment of the present invention, a collision apparatus when a single member in which both a first and a second injection nozzle are formed is incorporated in a chamber main body will be described. FIG. 1 is a schematic sectional view of a main part of the collision device.

  A chamber body 1 of the collision device includes a substantially cylindrical rear chamber housing 2, and a ball holder 3 that is placed in the housing 2 and rotatably supports a spherical hard body 10, and the ball holder is sandwiched between the front and rear. It is mainly composed of a rear support member 4 and a nozzle member 5 and a front chamber housing 6 that presses and fixes the nozzle member 5 against the chamber housing 2 from the front in contact with the ball holder 3. In this embodiment, the upstream side is the front and the downstream side is the rear along the fluid flow.

  The nozzle member 5 is formed with a first injection nozzle 11 and a second injection nozzle 12, and the first injection axis 11 x of the first injection nozzle 11 and the second injection axis of the second injection nozzle 12. 12x are different from each other on the surface of the spherical hard body 10 exposed on the front-side opening window of the ball holder 3, and are directed to positions eccentric to the spherical center of the spherical hard body 10. In the nozzle member 5 of the present apparatus shown in FIG. 1, the first injection axis 11x is decentered in the upper direction and the front direction with respect to the spherical hard body 10 and the second injection axis 12x is in the lower direction and the rear direction. Each injection nozzle (11, 12) is set so as to be eccentric in the direction.

  The front chamber housing 6 is formed with introduction passages (13, 14) for introducing the raw material liquid into the respective injection nozzles (11, 12), and the chamber main body 1 from the fluid supply device 20 provided with a pump or the like. The raw material liquid supplied under pressure is simultaneously supplied to the first injection nozzle 11 and the second injection nozzle 12 through the introduction flow path (13, 14).

  The raw material liquid is injected from the first and second injection nozzles (11, 12), becomes high-pressure jets, travels along the first injection axis 11x and the second injection axis 12x, and the spherical hard body 10 Collision processing such as emulsification, dispersion, or atomization of the raw material fine particles in the raw material liquid is performed by impact on the surface, and the rear chamber housing is connected via the outlet channel 15 formed in the rear support member 4. 2 is discharged from the outlet 16 at the rear end to the collection side.

  During this collision, the spherical hard body 10 is rotated in different directions by the component force of the collision force generated at each point. Therefore, the spherical hard body 10 is always synergistic in two directions during the collision process. The collision area on the surface of the spherical hard body 10 substantially acts over the entire surface.

  As a result, the impacted portions of the spherical hard body 10 are dispersed all over, and the conventional hard rotation does not cause groove-like damage due to the collision concentrated only on the same circumference. Since the life of the 10 itself is prolonged and the replacement frequency of the hard body can be greatly reduced, a collision apparatus suitable for an actual collision processing operation for a long time can be realized.

  In this embodiment, since the first and second injection nozzles (11, 12) are formed on the same nozzle member 5, both of the injection nozzles have a spherical rigid shape with an injection axis (11x, 12x). Since the amount of eccentricity with respect to the spherical center of the body 10 can be reduced and the collision positions can be made close to each other, the jet flow from any of the injection nozzles collides with the spherical hard body 10 with sufficient impact force, and good emulsification and fine particles Effect can be obtained.

  Note that the first injection nozzle 11 and the second injection nozzle 12 are simultaneously supplied with pressurized fluid, and the first injection is not limited to the configuration in which the injection collision occurs simultaneously, but the supply and stop of the pressurized fluid are switched to each other. You may comprise so that the collision process by the nozzle 11 and the 2nd injection nozzle 12 may be performed alternately.

  Hereinafter, as a second embodiment of the present invention, a collision when two separate members each having a collision treatment first injection nozzle and a rotation second injection nozzle formed in the chamber body are incorporated. Indicates the device. FIG. 2 is a schematic cross-sectional view of the main part of the collision device.

  A chamber main body 31 of the collision device includes a substantially cylindrical rear chamber housing 32, a ball holder 33 mounted in the housing 32 and rotatably supporting the spherical rigid body 40, and the ball holder 33 sandwiched between the front and rear. The rear support member 34, the first nozzle member 36, and the first nozzle member 36 are pressed and fixed to the chamber housing 32 from the front through the intermediate chamber housing 35 around the first nozzle member 36 in a contact state with the ball holder 33. The front chamber housing 37 and the second nozzle member 38 attached to the rear chamber housing 32 are mainly configured. Also in this embodiment, the upstream side is the front and the downstream side is the rear along the fluid flow.

  The first nozzle member 36 is formed with a first injection nozzle 41 for collision processing, the first injection axis 41x of which is parallel to the central axis of the chamber body 31 and with respect to the spherical center of the spherical hard body 40. Thus, it is set so as to be directed to a position eccentric to the depth side of FIG. In the first nozzle member 36, the first injection nozzle 41 suppresses the amount of eccentricity of the first injection axis 41x with respect to the spherical center of the spherical hard body 40 as much as possible, and most of the collision force is an impact for emulsification and atomization. It is set so that it can be used as a force to achieve a large collision processing effect.

  On the other hand, a second injection nozzle 42 for rotation is formed in the second nozzle member 38, and the second injection axis 42x is on a plane orthogonal to the central axis of the chamber body 31 and the first injection axis 41x. It is set so as to be directed to a position that is eccentric with respect to the spherical center of the spherical hard body 40 in the rear direction and in the depth direction of the drawing.

  In other words, the second nozzle member 38 is configured such that the second injection nozzle 42 is positioned so that the first injection nozzle 41 and the injection axis are orthogonal to each other on the paper surface of FIG. The collision position of the rotating jet due to the nozzle is positioned so that the effect of efficiently emulsifying and atomizing can be obtained, and at the same time without affecting the collision processing away from the collision position of the high-pressure jet by the first injection nozzle 41. It is set at a position where the spherical hard body 40 can be rotated such that it can cause a large displacement of the collision area along the rotation direction due to the jet collision of the first injection nozzle 41 more efficiently.

  The front chamber housing 37 is formed with an introduction flow path 43 for introducing the raw material liquid into the first injection nozzle 41 for collision processing, and is added to the chamber main body 31 from a fluid supply device 50 equipped with a pump and the like. The pressure-supplied raw material liquid is supplied to the first injection nozzle 41 through the introduction flow path 43, and is injected from the injection nozzle 41 to become a high-pressure jet flow along the first injection axis 41x. Collision processing such as emulsification, dispersion, or atomization of the raw material fine particles in the raw material liquid is performed by impact on the surface of the spherical hard body 40, and the outlet passage 44 formed in the rear support member 34 is Through the outlet 45 at the rear end of the rear chamber housing 32.

  In addition, the fluid supply device 50 applies the pressure corresponding to the collision force necessary for rotation to the second injection nozzle 42 for rotation using the medium liquid of the raw material liquid as the rotation fluid, that is, to the nozzle 41 for the first injection. It can be supplied at a lower pressure than the raw material liquid supplied at a high pressure for collision.

  Accordingly, the fluid supply device 50 is supplied to the second injection nozzle 42 in a collision processing stop state in which the pressure supply of the raw material liquid to the first injection nozzle 41 is continuously performed every predetermined time and the collision processing is stopped. If the rotation amount fluid is supplied at a low pressure, the spherical hard body 40 rotates due to the collision of the low pressure jet from the second injection nozzle 42, and the high pressure jet from the first injection nozzle 41 collides in the previous collision process. The circumferential area that has been moved is relatively moved from the high-pressure jet collision position, and in the next collision process, another surface area of the spherical hard body 40 becomes the circumferential area to be collided.

  If the supply of pressurized fluid to the chamber body 31 to the pump device of the fluid supply device 50, stop switching, pressure adjustment, and the like are controlled by a command via the control device 60 provided with a computer, a desired one is obtained in advance. Set the supply period and stop period from the start of fluid supply to each injection nozzle according to the switching operation of the injection process, and the pressure applied to the fluid supplied to each injection nozzle, and control the setting as an operation command By simply inputting to the device 60, it is possible to simply and automatically perform a collision processing operation that allows the fluid supply device 50 to execute a command and maintain a good rotation state of the hard body.
