Treatment agent dissolving device for liquid flow type fabric processing device, and liquid flow type fabric processing device

The present invention relates to a treatment agent dissolving device for a fluid flow type fabric treatment device for supplying a treatment agent for fabric treatment to a fluid flow type fabric treatment device for treating the fabric, and a fluid flow type fabric treatment device.

As one of fabric processing apparatuses for processing fabrics, there is known a liquid flow type fabric processing apparatus that circulates a liquid used for dyeing and processes the fabric. Conventionally, a treatment agent dissolving apparatus for a liquid flow type fabric processing apparatus for supplying a treatment agent for fabric treatment to the liquid flow type fabric treatment apparatus has been provided (Patent Document 1).

As shown in FIGS. 5 and 6, the treatment agent dissolving apparatus 9100 is connected to a liquid flow type fabric treatment apparatus 9000 provided with a circulation system 9130 through which a liquid used for dyeing circulates. Specifically, the processing agent dissolving apparatus 9100 includes a supply tank 9120 in which an input port 9110 into which the processing agent W is input is formed, and the supply tank 9120 is directly connected to the circulation system 9130. The supply tank 9120 supplies the processing agent W to the liquid used for dyeing that circulates in the circulation system 9130 when the processing agent W is input from the input port 9110.

JP-A-7-102466

By the way, the usage amount of the processing agent W is determined based on the amount of the fabric to be processed and the amount of liquid used for dyeing, and when the fabric is processed in an amount smaller than the determined amount, The fabric may not be properly processed. Therefore, it is desired that substantially the entire amount of the processing agent W is dispersed or dissolved in the liquid used for dyeing circulating in the liquid flow type fabric processing device 9000 without losing the pre-measured processing agent W. It is also desirable that the agent W be reliably dispersed or dissolved in the liquid.

By being put in the liquid used for dyeing as it is, it is mixed with the liquid used for dyeing by the dead weight of the processing agent W. In this case, in the treatment agent dissolving apparatus 9100, since there is no mechanism for sufficiently dispersing or dissolving the treatment agent W with respect to the liquid used for dyeing, the treatment agent W is not sufficiently dispersed or dissolved, but is dispersed or dissolved. In some cases, no treatment agent directly contacts the fabric. This may cause processing unevenness and fabric stains.

Therefore, in view of such circumstances, the present invention provides a treatment agent dissolving apparatus for a liquid flow type fabric treatment apparatus and a liquid flow type cloth treatment apparatus capable of sufficiently dispersing or dissolving the treatment agent in a liquid used for dyeing.

A tube 1022. The liquid is pressurized by the circulation pump 103. Therefore, in the present embodiment, the pressure in the second transfer pipe 1022 is higher than the pressure in the first transfer pipe 1021. The liquid is discharged from the discharge portion 1032 of the circulation pump 103 and returns to the retention tank 101 via the inlet portion 1012, and then passes through the outlet portion 1013 of the retention tank 101 and the first transfer pipe 1021 while processing the fabric. Return to the suction portion 1031 of the circulation pump 103. Thus, in the processing apparatus 100, the liquid circulates.

The supply member 11 stores the processing agent supplied from one end and supplies the stored processing agent to the dissolution apparatus 1 from the other end. The supply member 11 of this embodiment is a so-called hopper. The other end portion of such a hopper is, for example, a cylindrical shape whose diameter is reduced toward the other end.

2 and 3, the melting device 1 includes a main body 4 having an inner peripheral surface 3 that defines a flow path 2 and an injection unit 5 that injects liquid into the flow path 2. The main body 4 of the present embodiment includes a dissolving portion 40 that disperses or dissolves the treatment agent in the liquid, and a connecting portion 41 that connects the supply member 11 and the dissolving portion 40. Specifically, the melting part 40 and the connecting part 41 in the main body 4 are integrally formed. The supply member 11 is connected to one end 410 (the upper end in FIGS. 2 and 3) of the connecting portion 41.

The dissolution apparatus 1 of the present embodiment includes a liquid supply unit 7 that supplies a liquid along the inner peripheral surface 3. Furthermore, the dissolution apparatus 1 of the present embodiment includes a dispersion unit 8 that is connected to the flow path 2 and disperses the treatment agent remaining undissolved in the liquid pushed out from the flow path 2. Hereinafter, each component of the melting apparatus 1 will be described in detail.

The flow path 2 is a space surrounded by the inner peripheral surface 3. In the following, for convenience, the shape of the flow path 2 will be described, but this description will explain the shape of the inner peripheral surface 3 that defines the flow path 2 having the following shape.

The powdery processing agent is supplied from the supply member 11 from one end 20 (the upper end in FIG. 3) of the flow path 2. Furthermore, the other end 21 (the lower end in FIG. 3) of the flow path 2 is connected to the main body portion 1011 of the staying tank 101 via the transfer pipe 108 to supply the liquid to the circulation system 10.

The cross section of the flow path 2 of the present embodiment is, for example, circular. Here, the “cross section of the flow path 2” refers to a cross section in a direction perpendicular to the central axis α of the flow path 2. In addition, the flow path 2 of the present embodiment includes the first section 22, the second section 23 located on the one end 20 side of the first section 22, and the other end 21 side of the first section 22 in the dissolving section 40. A third section 24 located at In the melting part 40, the second section 23, the first section 22, and the third section 24 are positioned in order from the one end 20 to the other end 21 of the flow path 2.

The flow path cross-sectional area of the first section 22 is smaller than that of the second section 23. The cross-sectional area of the third section 24 is larger than the cross-sectional area of the first section 22. That is, the cross-sectional area of the first section 22 located between the one end 20 side and the other end 21 side is the second section 23 located on the one end 20 side and the third section 24 located on the other end 21 side. It is smaller than the cross-sectional area of the channel.

The second section 23 includes a first region 231 located on the one end 20 side, a second region 232 located between the one end 20 side and the other end 21 side, and a third region 233 located on the other end 21 side. Have. A first region 231, a second region 232, and a third region 233 are sequentially connected from one end 20 to the other end 21 of the flow path 2. The channel cross-sectional area of the first region 231 decreases as it approaches the other end 21 side. That is, the diameter of the first region 231 decreases toward the other end 21 side. In the present embodiment, the inclination angle of the first region 231 (between the portion defining the first region 231 on the inner peripheral surface 3 and the direction perpendicular to the central axis α of the flow path 2 (horizontal direction in FIG. 3)). The angle θ1) is larger than the angle of repose of the powdery treatment agent. As described above, since the inclination angle of the first region 231 is larger than the angle of repose of the powdery treatment agent, the powdery treatment agent slides down the portion defining the first region 231 on the inner peripheral surface 3. Cheap.

The inclination angle of the second region 232 (the angle θ2 between the portion defining the second region 232 on the inner peripheral surface 3 and the direction orthogonal to the central axis α of the flow channel 2 (horizontal direction in FIG. 3)) It is larger than the angle of repose of the powdery treatment agent. Therefore, for the same reason as in the first region 231, the powdery treatment agent easily slides down the portion defining the second region 232 on the inner peripheral surface 3. In addition, it is preferable that (theta) 2 is larger than the angle of repose of a powdery processing agent, and is 90 degrees or less. Further, the second region 232 is provided with an injection hole for injecting liquid into the flow path 2.

The flow path cross-sectional area of the third region 233 decreases as it approaches the other end 21. That is, the diameter of the third region 233 decreases as it approaches the other end 21 side. In the present embodiment, the inclination angle of the third region 233 (between the portion defining the third region 233 on the inner peripheral surface 3 and the direction perpendicular to the central axis α of the flow path 2 (horizontal direction in FIG. 3)). The angle θ3) is larger than the angle of repose of the powdery treatment agent. Therefore, for the same reason as in the first region 231, the powdery treatment agent easily slides down the portion that partitions the third region 233 on the inner peripheral surface 3.

In the flow path 2, the cross-sectional area of the second section 22 is the smallest.

The third section 24 has a first region 241 located on the one end 20 side and a second region 242 located on the other end 21 side.

The flow path cross-sectional area of the first region 241 increases as it approaches the other end 21 side. That is, the diameter of the first region 241 increases as it approaches the other end 21 side.

Similarly, the flow path cross-sectional area of the second region 242 increases as it approaches the other end 21 side. That is, the diameter of the second region 242 increases as it approaches the other end 21 side. Further, the inclination angle of the second region 242 (the angle θ5 between the portion defining the second region 242 on the inner peripheral surface 3 and the direction perpendicular to the central axis α of the flow path 2 (horizontal direction in FIG. 3)) Is the inclination angle of the first region 241 (the angle θ4 between the portion defining the first region 241 on the inner peripheral surface 3 and the direction perpendicular to the central axis α of the flow path 2 (horizontal direction in FIG. 3)) Bigger than.

Since the flow path 2 of the present embodiment has the above-described configuration, the powdery processing agent supplied from the one end 20 does not move in the horizontal direction (the horizontal direction in FIG. 3) in the flow path 2, It moves linearly in the direction from the one end 20 toward the other end 21.

The injection unit 5 is connected to the upstream part of the circulation system 10 than the part to which the other end 21 is connected. Liquid is supplied from the circulation system 10 to the injection unit 5 of the present embodiment via the transfer pipe 106 (see FIG. 1).

The injection unit 5 of the present embodiment injects liquid from the inner peripheral surface 3 into the flow path 2 as described above. In the present embodiment, the ejection unit 5 ejects the liquid into the flow path 2 from a plurality of positions (four injection holes in the present embodiment) spaced in the circumferential direction on the inner peripheral surface 3. In the present embodiment, the four injection holes are provided at equal intervals in the circumferential direction. In the present embodiment, in the direction of the central axis α of the flow path 2, each of the four injection holes is provided at a distance equal to the other end 21 of the flow path 2.

The injection unit 5 of the present embodiment includes a first portion 50 composed of a plurality of flow paths (four flow paths in the present embodiment) respectively communicating with a plurality of injection holes (four injection holes in the present embodiment). And a second portion 51 for supplying and distributing the liquid to the first portion 50.

1st site | part 50 is formed in the inside of the cylinder part which comprises the main body 4 (this embodiment melt | dissolution part 40). The cross section of the flow path that forms the first portion 50 is, for example, circular. The flow path that forms the first part 50 includes a first region 500 that communicates with the injection hole, and a second region 501 that communicates with the first region 500 and communicates with the second region 51. The channel cross-sectional area of the first region 500 is smaller than the channel cross-sectional area of the second region 501. Therefore, the liquid ejected from the first portion 50 is ejected vigorously on the inner peripheral surface 3 by passing through the first region 500. In addition, since the channel cross-sectional area of each 1st area | region 500 is equal, and the channel cross-sectional area of each 2nd area | region 501 is equal, the quantity of the liquid injected from four injection holes is equal.

The second portion 51 is connected to the first region 510 formed in the cylindrical portion constituting the main body 4 (in the present embodiment, the dissolving portion 40), and the main body 4 (in the present embodiment). Then, the 2nd area | region 511 which protruded outside the cylinder part which comprises the melt | dissolution part 40) is included. The first region 510 is continuous in the circumferential direction of the flow path 2. The first region 510 of the present embodiment has an annular shape when viewed from the central axis direction of the flow path 2.

The liquid flowing through the second region 511 is supplied to the first part 50 after passing through the first region 510. Thereby, the liquid flows in the first region 510 in the circumferential direction from the portion of the first region 510 where the second region 511 is connected.

The injection unit 5 injects the liquid supplied from the circulation system 10 in a direction having a velocity component from the one end 20 to the other end 21 in the flow path 2. The direction in which the liquid is ejected from the ejection holes of the ejection unit 5 is set so that the liquid ejected from the ejection holes flows smoothly downward in FIGS. 2 and 3. Specifically, the liquid is prevented from being ejected to a portion of the inner peripheral surface 3 where the inclination angle with the central axis α of the flow path 2 is large, and the intersecting liquid rebounds upward in FIGS. 2 and 3. In order to prevent this, the ejection direction of the liquid from the ejection hole of the ejection unit 5 is set. In the present embodiment, the liquid ejection direction from the ejection hole of the ejection section 5 intersects at one point on the central axis α of the flow path 2. Further, in the present embodiment, the location where the injection directions by the injection unit 5 intersect is located at the boundary between the first section 22 and the second section 23 of the flow path 2.

In the present embodiment, the angle between the liquid injection direction β by the injection unit 5 and the central axis α of the flow path 2 is the same for all four injection holes. In the present embodiment, the angle between the liquid ejection direction β by the ejection unit 5 and the central axis α of the flow path 2 is 45 ° or less, for example, 40 °. Furthermore, in the present embodiment, the angle between the liquid ejection direction β by the ejection unit 5 and the central axis α of the flow path 2 is such that the first region 231 of the second section 23 in the flow path 2 and the flow path 2 Is larger than the angle between the center axis α of the two.

The ejection unit 5 of the present embodiment ejects liquid into the first section 22 of the flow path 2, that is, the section where the flow path cross-sectional area of the flow path 2 is small. The channel cross-sectional area of the first section 22 of the channel 2 is set to such an extent that the powdery processing agent can be sufficiently dispersed or dissolved in the liquid used for dyeing.

As shown in FIG. 3, the liquid supply unit 7 is formed integrally with the main body 4 (in this embodiment, the connection unit 41). The liquid supply unit 7 of the present embodiment is disposed at a position (a position that is eccentric with respect to the central axis α of the flow path 2) that is shifted from the center of the cross section in the flow path 2 (the central axis α of the flow path 2). . Specifically, the liquid supply unit 7 of the present embodiment supplies liquid along the inner peripheral surface 3 in the circumferential direction of the inner peripheral surface 3 (in the present embodiment, the tangential direction with respect to the inner peripheral surface 3). In addition, the liquid is supplied from the circulation system 10 to the liquid supply unit 7 of the present embodiment via the transfer pipe 107 (see FIG. 1). The liquid supply is performed for an arbitrary period. The liquid supply is also performed during a period when the fabric is not treated, for example, during a pot wash.

The dispersion unit 8 disperses the treatment agent remaining undissolved in the liquid pushed out from the other end 21 of the flow path 2. In the present embodiment, the dispersion part 8 includes a cylindrical fixing part 80, a first dispersion member 81, and a second dispersion member 82. The first and second dispersion members 81 each disperse the treatment agent remaining undissolved in the liquid.

In the present embodiment, the other end 401 side of the main body 4 is arranged inside the fixed portion 80. The first dispersion member 81 is provided at the other end 21 of the flow path 2. The first dispersion member 81 of the present embodiment has a disk shape having a plurality of openings 810. The second dispersion member 82 is provided so as to overlap the first dispersion member 81 in the flow direction of the flow path 2 (the vertical direction in FIG. 3, the downward direction in the present embodiment). The second dispersion member 82 of the present embodiment has a disk shape having a plurality of openings 820. In the second dispersion member 82 of the present invention, the plurality of openings 820 in the second dispersion member 82 and the plurality of openings 810 in the first dispersion member 81 do not overlap (the central axis of the opening 810 and the central axis of the opening 820 are It is arranged so as to shift.

In this embodiment, there is a space between the first and

second dispersion members

81 and 82, but if a part of the opening 810 overlaps the opening 820, the first and

second dispersion members

81 and 82 are present. Even if there is no space between them (that is, even if the first and

second dispersion members

81 and 82 are in close contact with each other), the liquid can be circulated through the dispersion portion 8. In addition, when all of the openings 810 do not overlap with all of the openings 820, the liquid can be circulated through the dispersion portion 8 by making a space between the first and

second dispersion members

81 and 82.

The first dispersion member 81 and the second dispersion member 82 of the present embodiment are disposed in a region surrounded by the fixed portion 80 and the main body 4. Specifically, the first dispersion member 81 and the second dispersion member 82 are supported while being sandwiched between the fixing portion 80 and the main body 4. In the present embodiment, when the liquid is circulated through the dispersion part 8 through the opening 810 of the first dispersion member 81, a turbulent flow is generated in the dispersion part 8. Further, in the present embodiment, the first dispersion member 81 and the second dispersion member 82 are arranged so that the opening 810 of the first dispersion member 81 and the opening 820 of the second dispersion member 82 do not overlap.

With the above-described configuration, in the processing apparatus 100, the liquid moves as follows. First, a powdery processing agent is supplied from the one end 20 of the flow path 2 of the dissolution apparatus 1 by the supply member 11. In the dissolving apparatus 1, a negative pressure is generated due to the ejector effect caused by the liquid ejected from the ejecting unit 5, and thus this treatment agent is sucked into the other end 21 side of the flow path 2 and mixed with the liquid. The liquid in which the treatment agent is mixed is pushed out to the other end 21 of the flow path 2 and moves to the dispersion unit 8. In the dispersion unit 8, the treatment agent remaining in the liquid is dispersed or dissolved in the liquid by contact with portions other than the openings of the first dispersion member 81 and the second dispersion member 82 and turbulent flow generated in the dispersion unit 8. To do. The liquid that has passed through the dispersing unit 8 is supplied to the main body 1011 of the staying tank 101 via the transfer pipe 108 (see FIG. 1), and is then sucked into the circulation pump 103 from the outlet 1013 of the staying tank 101. Circulate through the circulation system 10.

Subsequently, the operation and effect of the dissolution apparatus 1 having the above configuration will be described.

In the melting device 1 having such a configuration, in the space (flow channel 2) surrounded by the inner peripheral surface 3, the liquid is vigorously ejected to generate a negative pressure due to the ejector effect, and the powder supplied to the space The treatment agent is sucked into the other end 21 of the flow channel 2 and is sufficiently dispersed or dissolved in the liquid. In addition, since the liquid to be ejected has a velocity component from the one end 20 to the other end 21 of the flow path 2, the liquid in which the powdery processing agent is dispersed or dissolved is pushed out from the other end 21. Therefore, the supplied powdery processing agent arrives one after another at a position (in this embodiment, the first section 22) toward which the jetted liquid is directed, and dispersion or dissolution is sequentially performed at this position. The treatment agent is efficiently dispersed or dissolved.

In the dissolving apparatus 1, since the ejector effect is enhanced by ejecting the liquid toward the first section 22 having a small flow path cross-sectional area, the powdery treatment agent is sucked into the other end 21 of the flow path 2. To further disperse or dissolve in the liquid. In addition, since the liquid is ejected toward the first section 22 having a small flow path cross-sectional area, the liquid is more easily brought into contact with the processing agent than when it is ejected toward the second section 23 having a large flow path cross-sectional area. Thereby, a processing agent and this liquid become easier to mix, and a processing agent can be further disperse | distributed or dissolved in a liquid.

In the dissolution apparatus 1, the jetted liquid intersects in the first section 22, and thus a negative pressure due to the ejector effect is likely to be generated above the intersecting portion. Thereby, since a processing agent falls efficiently from the supply member 11, a processing agent can be efficiently disperse | distributed or dissolved in a liquid.

Moreover, in the melting apparatus 1, the cross-sectional area of the first section 22 located between the one end 20 side and the other end 21 side is such that the second section 23 located on the one end 20 side from the first section 22 and the first section It is smaller than the cross-sectional area of the third section 24 located on the other end 21 side from the section 22. Therefore, the processing agent supplied from the one end 20 is easily sucked into the other end 21 side. As a result, the treatment agent and the liquid are easily mixed, and the treatment agent can be further dispersed or dissolved in the liquid.

In the melting apparatus 1, the liquid supply unit 7 causes the liquid to flow along the inner peripheral surface 3. Thereby, since the adhesion of the treatment agent to the inner peripheral surface 3 can be prevented, it is possible to realize the dissolving device 1 which is not easily contaminated. Moreover, blockage of the flow path 2 due to the progress of the adhesion of the treatment agent to the inner peripheral surface 3 can be prevented.

In the melting apparatus 1, the liquid supply unit 7 supplies liquid in the circumferential direction of the inner peripheral surface 3. Therefore, since this liquid moves along the circumferential direction of the inner peripheral surface 3 and falls due to gravity, the liquid flows spirally from one end 20 toward the other end 21 as a whole. Thereby, since the adhesion of the treatment agent to a wide range in the circumferential direction of the inner peripheral surface 3 can be prevented, the dissolution apparatus 1 which is not easily contaminated can be realized. Moreover, blockage of the flow path 2 due to the progress of the adhesion of the treatment agent to the inner peripheral surface 3 can be prevented.

In the melting apparatus 1, since the injection unit 5 does not protrude into the flow path 2, it is possible to suppress the injection unit 5 from blocking the flow of the powdery processing agent.

In the melting apparatus 1, the ejection unit 5 ejects liquid into the flow path 2 from a plurality of (four in this embodiment) positions spaced in the circumferential direction on the inner circumferential surface 3. Thereby, since a liquid is injected to a processing agent from a different direction, it becomes easy to mix a processing agent and a liquid, and a processing agent can be further disperse | distributed or dissolved in a liquid.

In the dissolution apparatus 1, even if the treatment agent remains undissolved, it contacts with the first dispersion member 81 and is crushed by this impact, or the treatment agent moves in the moving direction and is dispersed in the liquid in the flow path 2. Or dissolve. Therefore, the treatment agent and the liquid are easily mixed, and the treatment agent can be further dispersed or dissolved in the liquid.

Further, in the dissolving apparatus 1, even if the treatment agent remains undissolved, it is further crushed by this impact by contacting the second dispersion member 82, or the movement direction of the treatment agent is changed and the inside of the flow path 2 is changed. To disperse or dissolve in a liquid. Therefore, the treatment agent and the liquid are more easily mixed, and the treatment agent can be further dispersed or dissolved in the liquid.

The processing apparatus 100 including the dissolution apparatus 1 having such a configuration includes the dissolution apparatus 1, a supply member 11 that supplies a powdery treatment agent toward one end 20 of the flow path 2, and a treatment agent from the other end 21 of the flow path 2. And a circulation system 10 to which a liquid in which the liquid is dispersed or dissolved is supplied. Therefore, in the space (flow path 2) surrounded by the inner peripheral surface 3, the liquid processing agent supplied to the space is vigorously ejected, so that the powder processing agent Is sufficiently dispersed or dissolved in this liquid. Moreover, since the liquid to be ejected has a velocity component from one end 20 to the other end 21 of the flow path 2, the liquid in which the powdery processing agent is dispersed or dissolved is pushed out from the other end 21. As described above, the treatment agent is efficiently dispersed or dissolved.

The four injection positions in the injection unit 5 are provided at equal intervals in the circumferential direction, and each of the four injection holes is the same distance as the other end 21 of the flow path 2 in the direction of the central axis α of the flow path 2. Only provided apart. Further, the angle between the liquid ejection direction β by the ejection unit 5 and the central axis α of the flow path 2 is the same for all four ejection positions. As a result, the momentum and amount of the liquid sprayed onto the powdery processing agent are equal to each other, so that the processing agent can be dispersed or dissolved without unevenness.

Hereinafter, the processing agent dissolution apparatus according to the second embodiment will be described with reference to FIG. The same code | symbol is attached | subjected about the same structure as 1st Embodiment among the structures of 2nd Embodiment.

The dissolution apparatus 1001 includes a main body 1004 having an inner peripheral surface 1003 that defines a flow path 1002, an injection unit 1005, a liquid supply unit 7, and a dispersion unit 8. The main body 1004 includes a dispersion or dissolution part 1040 in which the treatment agent is dispersed or dissolved in the liquid, and a connection part 1041 that connects the supply member 11 and the dispersion or dissolution part 1040.

The flow path 1002 includes a first section 1024, a second section 1025 located on the one end 1020 side of the first section 1024, and a third section 1026 located on the other end 1023 side of the first section 1024. In the channel 1002, the channel cross-sectional area of the first section 1024 is the smallest.

The ejection unit 1005 of the present embodiment ejects liquid from one position (one through hole) passing through the central axis α of the flow channel 1002 in a direction from one end 1020 to the other end 1023 in the flow channel 1002. That is, the liquid ejection direction by the ejection unit 1005 of the present embodiment is the same as the flow direction of the powdery processing agent. In addition, the through hole of the present embodiment is located near the central axis α of the flow path 1002.

The injection unit 1005 of this embodiment includes a first part 1050 that communicates with one injection hole and has a circular cross section, a second part 1051 that communicates with the first part 1050 and has a circular cross section, and a second part. A third portion 1052 that communicates with 1051 and is connected to the circulation system 10 to supply liquid. The first part 1050 and the second part 1051 of this embodiment are provided in the flow path 1002.

The third portion 1052 has a cylindrical shape. The third portion 1052 includes a first region 1520 and a second region 1521 that is connected to the first region 1520 and protrudes to the outside of the cylindrical portion that constitutes the main body 1004. In the present embodiment, the first region 1520 is formed integrally with the main body 1004 (in the present embodiment, the connecting portion 1041). In addition, the first region 1520 is connected to the second cylindrical portion 1053 that surrounds the second portion 1051. Note that a first tube portion 1054 surrounding the first portion 1050 is connected to the second tube portion 1053.

The liquid flowing through the second region 1521 passes through the first region 1520 and then passes through the first portion 1050 and is injected into the flow path 1002.

The inner diameter of the first tube portion 1054 and the flow path cross-sectional area of the first section 1024 in the flow path 1002 are set so that the ejector effect functions effectively.

Also in the melting apparatus 1001 having such a configuration, the liquid is vigorously injected into the powdery processing agent supplied to the space in the space (flow path 1002) surrounded by the inner peripheral surface 1003. The powdery treatment agent is sufficiently dispersed or dissolved in this liquid. In addition, since the liquid to be ejected has a velocity component from one end 1020 to the other end 1023 of the flow path 1002, the liquid in which the powdery processing agent is dispersed or dissolved is pushed out from the other end 1023. Therefore, the supplied powdery processing agent successively reaches the position where the liquid is ejected, and the processing agent is efficiently dispersed or dissolved by sequentially performing dispersion or dissolution at this position.

The surface 1055 located in the direction opposite to the flow direction of the flow path 1002 in the second cylinder portion 1053 (the upward direction in FIG. 4) is convex in this direction and has a smooth shape. Therefore, even if the powdery processing agent supplied from the one end 1020 is placed on the surface 1055 of the second cylindrical portion 1053, it is easily slipped off. Thereby, it can suppress that the injection part 1005 obstruct | occludes the flow of a powdery processing agent.

The melting apparatus 1 according to the present invention is not limited to the configuration of the above embodiment, and various modifications can be made without departing from the gist of the present invention.

In the above embodiment, in the flow path 2, the flow path cross-sectional area of the third section 24 located closer to the other end 21 than the first section 22 is larger than the flow path cross-sectional area of the first section 22. The channel cross-sectional area of the three sections 24 may be smaller than the channel cross-sectional area of the first section 22 or may be equal to the channel cross-sectional area of the first section 22. Even in this case, since the negative pressure is generated due to the ejector effect of the liquid ejected from the ejecting section 5, the treatment agent is sucked into the other end 21 side of the flow path 2 and mixed with the liquid. Therefore, the treatment agent can be sufficiently dispersed or dissolved in the liquid.

In this case, the flow path cross-sectional area of the second section 23 located on the one end 20 side of the first section 22 is larger than the flow path cross-sectional area of the first section 22, and the ejection unit 5 flows the liquid. If it injects to the 1st area 22 with a small channel cross-sectional area, it will be easy to contact a processing agent rather than the case where the liquid is injected to the 2nd area 23 with a large channel cross-sectional area. Thereby, a processing agent and this liquid become easier to mix, and a processing agent can be more fully disperse | distributed or dissolved in a liquid.

Furthermore, the cross-sectional area of the flow path 2 is uniform at each position in the direction of the central axis α of the flow path 2, that is, even if the flow path 2 is a cylindrical flow path, it is surrounded by the inner peripheral surface 3. In the space (flow channel 2), the liquid processing agent is sufficiently dispersed or dissolved in the liquid by vigorously ejecting the liquid to the powder processing agent supplied to the space. .

In the above embodiment, the flow path 2 has a circular cross section, but may have other shapes such as an ellipse or a polygon. When the cross section is elliptical or polygonal, the central axis of the flow path is an axis passing through the center of gravity of the cross section.

In the above embodiment, the flow path 2 is linear, but a part of the flow path 2 may be curved or may be entirely curved. Even in this case, even if the flow path 2 is not linear, in the space (flow path 2) surrounded by the inner peripheral surface 3, the powdery treatment agent supplied to the space When the liquid is jetted vigorously, the powdery treatment agent is sufficiently dispersed or dissolved in the liquid.

In addition, when the injection part 1005 exists inside the flow path 1002 like 2nd Embodiment, the 1st cylinder part 1054 and the 2nd cylinder part which surround the injection part 1005 corresponding to the shape of the flow path 1002. 1053 may be bent. That is, the cylindrical portion surrounding the injection portion 1005 disposed in the bent portion of the flow path 1002 may be partially or wholly bent, and even in this case, When the liquid is jetted vigorously, the powdery treatment agent is sufficiently dispersed or dissolved in the liquid.

In the above embodiment, since the dissolution part 40 and the connection part 41 in the main body 4 are integrally formed, the liquid supply part 7 is arranged close to the other end 21 of the flow path 2, thereby reducing the size of the dissolution apparatus. Can be achieved. However, the present invention is not limited to this, and the main body 4 may have a dissolving portion and a connecting portion formed individually. The liquid supply unit 7 may be disposed at a portion where the inner peripheral surface 3 that defines the flow channel 2 is inclined with respect to the central axis α of the flow channel 2.

In the above embodiment, in the injection unit 5, the plurality of injection holes are provided at equal intervals in the circumferential direction, but may be provided at different intervals. In addition, since the channel cross-sectional areas of the first regions 510 are equal and the channel cross-sectional areas of the second regions 520 are equal, the amounts of liquid ejected from the four ejection positions were equal. The amount of liquid ejected from the four ejection positions may be varied by varying the channel cross-sectional area and the channel cross-sectional area of the second region 520.

In the above embodiment, the injection hole is located on the inner peripheral surface 3 in the first embodiment, and the injection hole is located near the central axis α of the flow path 1002 in the second embodiment. And near the central axis of the flow path.

In the above embodiment, in the direction of the central axis α of the flow path 2, each of the four injection holes is provided at a distance equal to the other end 21 of the flow path 2. However, in the injection unit 5, this distance may not be uniform. In this case, the jetting unit is designed so that the angle between the jetting direction β of the liquid by the jetting unit and the central axis α of the flow path 2 is different in the four jetting holes. The crossing position in the injection direction can be made one point.

In the above embodiment, the powdery treatment agent supplied from the one end 20 has moved linearly in the direction from the one end 20 to the other end 21 without moving in the flow path 2 in the horizontal direction. The body-like treatment agent may move in the direction from the one end 20 toward the other end 21 while rotating in the flow path 2 in the circumferential direction (moving so as to spiral).

In the above embodiment, the liquid supply unit 7 is supplied with the liquid from the circulation system 10, but the liquid supply unit 7 may be supplied with a liquid from a location (for example, outside) different from the circulation system 10. In this case, the liquid supply unit 7 may be supplied with a liquid that is not mixed with the treatment agent and that can disperse or dissolve the treatment agent, for example, water. In this way, if water is allowed to flow from the liquid supply unit 7 to the inner peripheral surface 3, it is easier to disperse or dissolve the processing agent attached to the inner peripheral surface 3 than to flow a liquid mixed with the processing agent in advance. Can be further prevented from adhering to the inner peripheral surface 3. Moreover, in the said embodiment, although the liquid supply part 7 was distribute | arranged to the position eccentric with respect to the center axis | shaft (alpha) of the flow path 2, it may not be restricted to this but may be distribute | arranged so that it may be located on the center axis | shaft (alpha). Good.
