By the way, in the above conventional melting apparatus, by sucking a gas (including a gas existing between particles of a powder) together with a raw material sucked into an introduction chamber, specifically, a powder as a solute, The efficiency of the dissolution pump is reduced, and particularly when the viscosity of the solution is high, there is a problem that microbubbles remain in the solution and the quality of the solution decreases.
In addition, the presence of microbubbles in the solution to be circulated in the suction section reduces the efficiency of the dissolution pump. In particular, the solute is water-absorbing like starch or a superabsorbent polymer (for example, carboxymethylcellulose (CMC)). In the case of a hardly soluble substance that gels as a result, a semi-dissolved substance such as a microgel remains, and the quality of the solution is degraded.

  In view of the problems of the above-described conventional dissolution apparatus, the present invention eliminates microbubbles contained in a solution and enables a semi-dissolved substance such as a microgel to be completely dissolved. An object of the present invention is to provide a dissolution apparatus capable of obtaining a high-quality dissolution solution.

In order to achieve the above object, the melting apparatus of the present invention rotates a rotating blade, sucks a solute and a solvent from a suction portion as primary materials into an introduction chamber, passes through a throttle channel, and stirs with the rotating blade. A first dissolution pump for performing primary dissolution having a circulation flow path and a discharge flow path for discharging the dissolution liquid from the discharge section and circulating a part of the dissolution liquid discharged from the discharge section to the suction section; The rotating blade is rotated, and the solution discharged from the discharge channel of the first dissolution pump from the suction portion is sucked into the introduction chamber as a secondary material, passed through the throttle channel, and stirred by the rotating blade. A second dissolution pump for performing secondary dissolution having a circulation flow path and a discharge flow path for discharging a dissolution liquid from the discharge section and circulating a part of the dissolution liquid discharged from the discharge section to the suction section; It is characterized by comprising.
The dissolution apparatus performs primary dissolution by sucking solute and solvent as primary raw materials from the suction part of the first dissolution pump into the introduction chamber, and then discharging the first dissolution pump from the suction part of the second dissolution pump. By sucking the solution discharged from the flow path into the introduction chamber as a secondary material and performing the second dissolution, the suction of gas can be eliminated in the second dissolution by the second dissolution pump.

  In this case, the throttle channel can be constituted by a through hole formed in a stator disposed between the rotor blade and the introduction chamber.

In addition, separation means for separating and supplying the solution to the circulation channel and the discharge channel by specific gravity can be provided at the discharge portions of the first dissolution pump and the second dissolution pump.
This separation means can separate and supply a solution component having a large specific gravity which has not been completely dissolved to the circulation channel and a solution component having a small specific gravity having been completely dissolved to the discharge channel.

  And the 1st dissolution pump and the 2nd dissolution pump can be constituted by one dissolution pump, or can be constituted by individual dissolution pumps.

Here, in the case of a single dissolution pump, a closing means for closing the suction of the primary raw material consisting of the solute and the solvent in the suction portion of the dissolution pump, and a storage means for storing the dissolved liquid that has undergone the primary dissolution. And the solution obtained by the primary dissolution stored in the storage means is sucked into the introduction chamber of the dissolution pump in the state where the suction of the primary material is closed by the closing means.
This dissolution apparatus is a solution obtained by performing primary dissolution performed while sucking a primary material composed of a solute and a solvent, and a primary solution stored in a storage unit in a dissolution pump in a state where the suction of the primary material is closed by a closing unit. Secondary melting performed while inhaling as a secondary raw material is carried out batchwise with a single dissolution pump.

  In this case, in a state in which the suction of the primary raw material is closed, the dissolved solution that has been subjected to the primary dissolution stored in the storage means is supplied as the secondary raw material to the solvent supply unit in the suction unit. Can do.

In the case of using an individual dissolution pump, the discharge channel of the first dissolution pump and the suction part of the second dissolution pump are connected via a connection channel.
Here, the second dissolution pump may be composed of one dissolution pump, or may be composed of two or more units, and the connection method may be a parallel connection in addition to a serial connection. it can.
This melting apparatus performs primary melting and secondary melting in a continuous manner.

According to the melting apparatus of the present invention, the second melting pump can perform the second melting in a state where the suction of the gas is eliminated, so that the efficiency of the melting pump can be improved, and the introduction chamber is set to a high vacuum. In this state, cavitation is caused in the solution passing through the throttle channel, and the dissolution is promoted by expansion of bubbles contained in the solution and impact caused thereby, and microbubbles remaining in the solution are removed. Can be extinguished.
In addition, the ability to eliminate the microbubbles remaining in the solution to be circulated in the inhalation part can further improve the efficiency of the dissolution pump, and even if the solute is a hardly soluble substance, it is in a semi-dissolved state. The substance can be completely dissolved.
Thereby, it is possible to obtain a high-quality solution that does not leave microbubbles or a semi-dissolved substance in the solution.

  Further, the throttle channel is configured by a through hole formed in the stator disposed between the rotor blade and the introduction chamber, so that the primary material and the secondary material and the circulating solution pass through the through hole. In this case, a shearing force can be applied by the rotating blades, which can further promote dissolution.

  In addition, by providing separation means for separating and supplying the substance to be dissolved dissolved by specific gravity into the circulation path and the discharge path at the inlet of the circulation path, a solution component having a high specific gravity and not completely dissolved can be selected. Therefore, it is possible to circulate through the circulation flow path, to prevent the solution component not completely dissolved from being discharged from the discharge flow path, and to improve the operation efficiency of the apparatus.

  Further, by configuring the first dissolution pump and the second dissolution pump with a single dissolution pump, the cost of the apparatus can be reduced, and the installation space of the apparatus can be reduced. Cleaning and maintenance work of the dissolution pump can be performed easily.

  Further, in a state where the suction of the primary raw material is closed, the solution that has been subjected to the primary dissolution stored in the storage means is configured as a secondary raw material, and is supplied to the solvent supply unit in the suction unit, It is not necessary to separately provide a secondary raw material supply unit in the dissolution pump, and the structure of the dissolution pump can be simplified.

  Moreover, a melt | dissolution operation | movement can be performed continuously by comprising a 1st melt | dissolution pump and a 2nd melt | dissolution pump with a separate melt | dissolution pump.

A first dissolution pump 1A that performs primary dissolution including a circulation flow path 26 and a discharge flow path 25 that discharge the dissolution liquid from the section 12 and circulate a part of the dissolution liquid discharged from the discharge section 12 to the suction section 11. Then, the rotating blade 13A is rotated, and the solution discharged from the discharge channel 25 of the first dissolution pump 1A from the suction unit 11 is sucked into the introduction chamber 15 as a secondary material and passes through the throttle channel S. The circulation flow path 26 and the discharge flow path 25 are used to cause the solution to be discharged from the discharge unit 12 and to circulate a part of the solution discharged from the discharge unit 12 to the suction unit 11. Having secondary dissolution It is to be composed of the second dissolution pump 1B performed.

The suction part 11 includes a closing means 6 for closing the suction of the primary raw material composed of a solute and a solvent, and a storage means 7 for storing the dissolved solution after the primary dissolution, and performs the primary dissolution stored in the storage means 7. The dissolved solution is used as a secondary raw material and is sucked into the introduction chamber of the dissolution pump 1A in a state in which the primary raw material is closed by the closing means 6.
As a result, the dissolution apparatus A is stored in the storage means 7 in the primary dissolution performed while sucking the primary raw material composed of the solute and the solvent, and in the dissolution pump 1 in a state where the suction of the primary raw material is closed by the closing means 6. The secondary dissolution performed while sucking the dissolved solution that has been subjected to the primary dissolution as a secondary raw material can be performed batch-wise with a single dissolution pump 1.

  The dissolution pump 1 is provided with a solute supply mechanism 3 for supplying a solute to the dissolution pump 1 and a solvent supply mechanism 4 for supplying a solvent, while the solvent is swung from the solvent supply mechanism 4 to the mixing nozzle 5. By supplying the initial mixture of the solute and the solvent, the primary raw material composed of the solute and the solvent can be smoothly supplied to the dissolution pump 1 by sucking from the suction portion 11 of the dissolution pump 1. I can do it.

The solute supply mechanism 3 supplies powder as a solute to the dissolution pump 1 by a predetermined amount. In this embodiment, the measurement rotator 34 rotatably disposed in the casing 30 and the measurement rotator. 34 is constituted by a drive mechanism M ′ for rotating the drive.
The solute supply mechanism 3 is formed with an expansion chamber 33 that is maintained at a lower pressure than the solute supply port 31 by the suction force acting from the solute discharge port 32, and with the rotation of the metering rotator 34, Each solute storage chamber 34a is configured to change between a positive pressure state and a negative pressure state.
The solute storage chamber 34 a is configured to open at the outer peripheral surface and the central portion of the measuring rotator 34, and the opening on the outer peripheral surface side of the measuring rotator 34 is in an open state of the solute supply port communicating with the solute supply port 31. In addition to being closed by the casing 30 except for the expansion chamber open state communicating with the expansion chamber 33, the opening on the center side of the metering rotating body 34 is in a sealed state (not communicating with the solute supply port 31 and the expansion chamber 33) and An opening closing member 35 is unevenly distributed at the center of the metering rotator 34 so as to be closed when the solute supply port is open, and is fixed to the casing 10.
Further, the measuring rotator 34 is disposed on the disk member 34c disposed on the drive shaft of the drive mechanism M ′ so that the solute storage chamber 34a opens at the outer peripheral surface and the center of the measuring rotator 34. By attaching a plurality of (eight in this embodiment) plate-like partition walls 34b radially excluding the central portion at equal intervals, the solute storage chambers 34a are partitioned and formed at equal intervals in the circumferential direction. I have to.
The supply amount of the powder as the solute can be adjusted by changing the number of rotations of the measuring rotator 34 by the drive mechanism M ′ that rotationally drives the measuring rotator 34.
The solute supply mechanism 3 can continuously supply a predetermined amount of powder by stabilizing the flow rate of the powder without the powder adhering and depositing in the solute storage chamber 34a and the like.

  The solvent supply mechanism 4 includes a flow meter and supplies a predetermined amount of liquid as a solvent to the dissolution pump 1.

  The configuration of the dissolution pump 1 is not particularly limited as long as it can suck and dissolve the primary raw material and the secondary raw material and the circulating dissolved liquid with a single dissolution pump. In the embodiment, as shown in FIG. 2 to FIG. 3, a plurality of rotor blades 13 </ b> A project from the outer periphery of the rotor 13 attached to the drive shaft of the drive mechanism M inside the cylindrical casing 10. The solute and the solvent are sucked into the introduction chamber 15 as primary raw materials from the suction part 11 and stirred, and the solution is discharged from the discharge part 12.

In this case, the casing 10 includes a cylindrical casing body 10A and a front casing 10B and a rear casing 10C disposed on the front side (left side in FIG. 2) and the rear side (right side in FIG. 2) of the casing body 10A. In addition, the casing body 10A is provided with a discharge portion 12 that discharges the dissolved liquid that is dissolved by stirring.
A cylindrical stator 14A is disposed in the front casing 10B so as to be positioned between the rotary blade 13A and the introduction chamber 15, and the throttle channel S is configured by through holes Sa and Sb formed in the stator 14A. Like to do.
The throttle channel S can be constituted by a slit or a nozzle in addition to the through hole.

If necessary, a stator 14B in which a through hole (a slit-like long hole in this embodiment) is formed as the throttle channel S can be disposed on the outer peripheral side of the rotary blade 13A.
Thereby, when passing through a through-hole with respect to a solution, a shear force can be made to act by a rotary blade, and melt | dissolution can be accelerated | stimulated.

Further, a filter funnel-shaped partition plate 16 is fixed to the rotor 13 via a plurality of bosses 16a inside the rotor blade 13A and further inside the stator 14A.
This partition plate 16 is introduced from one suction portion 11A of the suction portion 11 into an introduction chamber 15A (this introduction chamber) into which a solute and a solvent for sucking a primary material composed of a solute and a solvent that are initially mixed in the mixing nozzle 5 are introduced. 15A, in the case of secondary dissolution, the dissolved solution that has been subjected to the primary dissolution stored in the storage means 7 is introduced as a secondary raw material.) And a part of the dissolved solution discharged from the discharge unit 12 However, it circulates through the other suction part 11B and partitions the introduction chamber 15B to be introduced, and the sliding part between the partition plate 16 and the casing 10 has a step-like labyrinth structure, The primary material can be smoothly sucked into the introduction chamber 15A.

Here, since the introduction chamber 15 is divided into the introduction chamber 15A and the introduction chamber 15B, in this embodiment, as shown in FIG. 3, the through holes Sa and Sb formed in the stator 14A are formed. The shape of the through hole Sa facing the introduction chamber 15A is set to a circular shape that prevents the primary material from being clogged, and the through hole Sb facing the introduction chamber 15B is set to an oval shape in which shearing force by the rotating blades easily acts on the solution. I am doing so.
Here, the shape of the through holes Sa and Sb can be arbitrarily set according to the properties of the primary raw material and the secondary raw material, and the circulated solution, for example, as in the second embodiment to be described later. In the case where the first dissolution pump 1A that performs dissolution and the second dissolution pump 1B that performs secondary dissolution are configured by separate dissolution pumps, the first dissolution pump 1A and the second dissolution pump 1B The shapes of the through holes Sa and Sb formed in the stator 14A can be different.

The discharge unit 12 of the dissolution pump 1 is provided with separation means 2 for separating and supplying the solution to the circulation channel 26 and the discharge channel 25 by specific gravity.
In this embodiment, the separating means 2 is arranged such that an introduction pipe 21 connected to the discharge part 12 of the dissolution pump 1 protrudes from the bottom surface of the cylindrical container 20 and is disposed above the cylindrical container 20. 25, a discharge port 22 connected to 25, a circulation port 23 connected to the circulation flow path 26 in the lower portion, and a twist plate 24 for turning the flow of the solution discharged from the introduction pipe 21 at the discharge end of the introduction pipe 21 It arranges and constitutes.
Instead of the torsion plate 24 or together with the torsion plate 24, an agitation blade for agitating the solution discharged from the introduction pipe 21 may be disposed above the discharge end of the introduction pipe 21.
By providing this separation means 2, a solution component having a large specific gravity which is not completely dissolved is separated and supplied to the circulation channel 26, and a solution component having a small specific gravity dissolved is supplied to the discharge channel 25. It is possible to prevent the solution component that is not completely dissolved from being discharged from the discharge flow path 25 and to improve the operation efficiency of the apparatus.

  The closing means 6 makes it possible to selectively close the suction of the primary material composed of the solute and the solvent into the suction portion 11 of the dissolution pump 1. In this embodiment, the closing means 6 is substantially the same as the inner diameter of the flow path. A partition plate having a passage hole of the same diameter is disposed at the tip of the cylinder, and a shutter valve that moves the partition plate perpendicular to the flow path is used.

The closing means 6 can be disposed at any location as long as it can selectively close the suction of the primary material composed of the solute and the solvent into the suction portion 11 of the dissolution pump 1. In the embodiment, a shutter valve is provided between the solute supply mechanism 3 and the mixing nozzle 5, and the suction of the solvent into the suction part 11 of the dissolution pump 1 is closed and opened in the solvent supply path 40. This is performed by the valve 41.
In the present embodiment, in a state in which the suction of the primary raw material is closed, the solution obtained by the primary dissolution stored in the storage means 7 is supplied as the secondary raw material to the supply path 40 which is a solvent supply path. It is configured so that.
Thereby, it is not necessary to separately provide a secondary raw material supply unit in the dissolution pump 1, and the structure of the dissolution pump 1 can be simplified.

The storage means 7 is used for storing the dissolved liquid that has undergone primary dissolution and discharged from the discharge port 22 of the separation means 2 via the discharge flow path 25, and can be stored in any form such as a tank or a hopper. Means can be used.
In this embodiment, the storage means 7 uses a tank 70, connects the discharge flow path 25 to the inlet 71 formed in the upper part of the tank 70, and supplies the secondary raw material to the outlet 72 formed in the lower part. A flow path 44 is connected, and the secondary raw material flow path 44 is connected to a supply path 40 that is a supply part of a solvent via an on-off valve 42.
In addition, the tank 70 is provided with a stirring blade 73 that is rotationally driven by a drive mechanism 74 so that the solution stored in the tank 70 can be stirred.
Further, the tank 70 may be provided with an air release valve (not shown) as necessary to degas bubbles contained in the solution.

The dissolution apparatus A starts the operation of the dissolution pump 1 while supplying the solute and the solvent from the solute supply mechanism 3 and the solvent supply mechanism 4 to the dissolution pump 1 as primary materials.
The solute and the solvent are initially mixed in the mixing nozzle 5 and then introduced into the introduction chamber 15A from the suction portion 11A of the dissolution pump 1.
Then, by passing through the through hole Sa formed in the stator 14A and the through hole formed in the stator 14B disposed on the inner side and the outer side of the rotary blade 13A, the stirring and melting are performed while receiving a shearing action, and the discharge unit 12 It is discharged from.

  The lysate discharged from the discharge part 12 is separated by the separating means 2 and the lysate component having a large specific gravity which is not completely dissolved is supplied from the suction part 11B of the lysis pump 1 to the introduction chamber 15B via the circulation channel 26. By being introduced and passing through the through hole Sb formed in the stator 14A and the through hole formed in the stator 14B, the mixture is stirred and dissolved while being subjected to a shearing action, and discharged from the discharge unit 12, while the dissolution with a small specific gravity is completed. The dissolved solution component is stored in the tank 70 as the storage means 7 through the discharge channel 25.

  When a predetermined amount of the primary raw material is supplied, the closing means 6 closes the suction of the primary raw material made of the solute and the solvent to complete the primary dissolution and perform the primary dissolution stored in the storage means 7. By using the dissolved solution as a secondary material and introducing it into the introduction chamber 15A from the suction part 11A of the dissolution pump 1 in a state where the suction of the primary material is closed by the closing means 6, and operating the dissolution pump 1 in the same manner as the primary dissolution. Secondary dissolution is performed.

In this secondary melting, the efficiency of the melting pump 1 can be improved by closing the suction of the primary raw material and operating the melting pump 1 in a state where the suction of the gas is eliminated, and the introduction chambers 15A and 15B. In a high vacuum state, cavitation is caused in the solution passing through the through holes Sa formed in the stator 14A as the throttle channel S and the through holes formed in the stator 14B, and expansion of bubbles contained in the solution Due to the impact caused by the above, dissolution can be promoted and the microbubbles remaining in the solution can be eliminated.
In addition, since the microbubbles remaining in the solution to be circulated in the suction part 11B can be eliminated, the efficiency of the dissolution pump 1 can be further improved, and even when the solute is a hardly soluble substance, it is semi-dissolved. The substance in the state can be completely dissolved.

In the present embodiment, the solution that has undergone secondary dissolution is temporarily returned to the tank 70 as the storage means 7 via the discharge channel 25, and further to the dissolution pump 1 as necessary. After repeating this circulation, the opening / closing valves 42 and 43 are opened and closed, and then sent to the next step N.
Thereby, it is possible to obtain a high-quality solution that does not leave microbubbles or a semi-dissolved substance in the solution.

The dissolution apparatus B includes a first dissolution pump 1A and a second dissolution pump 1B, and connects the discharge flow path 25 of the first dissolution pump 1A and the suction part 11 of the second dissolution pump 1B. The connection is made through the flow path 27.
Thus, the dissolution apparatus B continuously performs primary dissolution performed while inhaling the primary material composed of the solute and the solvent, and secondary dissolution performed while inhaling the solution obtained by the primary dissolution as the secondary material. To be able to.
Here, the configuration of the first dissolution pump 1A and the second dissolution pump 1B does not necessarily require the dissolution pump 1 of the dissolution apparatus A of the first embodiment and the closing means 6 for closing the suction of the primary raw material. It is basically the same except that it is not.

  In this embodiment, the first dissolution pump 1A is composed of one dissolution pump 1A, and the second dissolution pump 1B is composed of two dissolution pumps 1Ba, 1Bb (here, the dissolution pump 1Bb Shows the example in which three dissolution pumps 1A, 1Ba, 1Bb are connected in series. The number of dissolution pumps and the connection method (series connection) In addition, parallel connection can be used in combination.) Can be arbitrarily set according to the properties of the primary material and the secondary material.

Here, in the connection flow path 27 that connects the first dissolution pump 1A and the second dissolution pump 1Ba and the connection flow path 27a that connects the second dissolution pump 1Ba and the second dissolution pump 1Bb, the storage means 8 is provided. To intervene.
The storage means 8 is for temporarily storing the solution, and any type of storage means such as a tank or a hopper can be used.

As a solution, the solution is supplied.
In addition, the storage means 8 may be provided with an air release valve (not shown) as necessary to degas bubbles contained in the solution.

In the secondary melting performed by operating the second dissolution pumps 1Ba and 1Bb, the dissolution apparatus B is operated by operating the second dissolution pumps 1Ba and 1Bb in a state where gas suction is eliminated. The melting pumps 1Ba and 1Bb can be improved in efficiency, the introduction chambers 15A and 15B are brought into a high vacuum state, and a through hole Sa formed in the stator 14A as the throttle channel S and a through hole formed in the stator 14B are provided. Cavitation is caused in the passing solution, and the expansion of bubbles contained in the solution and the impact generated thereby promote the dissolution and eliminate the microbubbles remaining in the solution. .
In addition, since the microbubbles remaining in the solution to be circulated in the suction part 11B can be eliminated, the efficiency of the dissolution pump 1 can be further improved, and even when the solute is a hardly soluble substance, it is semi-dissolved. The substance in the state can be completely dissolved.

  The other configuration and operation of the present embodiment are the same as those of the first embodiment.

By the way, in the above conventional melting apparatus, by sucking a gas (including a gas existing between particles of a powder) together with a raw material sucked into an introduction chamber, specifically, a powder as a solute, The efficiency of the dissolution pump is reduced, and particularly when the viscosity of the solution is high, there is a problem that microbubbles remain in the solution and the quality of the solution decreases.
In addition, the presence of microbubbles in the solution to be circulated in the suction section reduces the efficiency of the dissolution pump. In particular, the solute is water-absorbing like starch or a superabsorbent polymer (for example, carboxymethylcellulose (CMC)). In the case of a hardly soluble substance that gels as a result, a semi-dissolved substance such as a microgel remains, and the quality of the solution is degraded.

Further, the measuring rotator 34 is disposed on the disk member 34c disposed on the drive shaft of the drive mechanism M ′ so that the solute storage chamber 34a opens at the outer peripheral surface and the center of the measuring rotator 34. By attaching a plurality of (eight in this embodiment) plate-like partition walls 34b radially excluding the central portion at equal intervals, the solute storage chambers 34a are partitioned and formed at equal intervals in the circumferential direction. I have to.
The supply amount of the powder as the solute can be adjusted by changing the number of rotations of the measuring rotator 34 by the drive mechanism M ′ that rotationally drives the measuring rotator 34.
The solute supply mechanism 3 can continuously supply a predetermined amount of powder by stabilizing the flow rate of the powder without the powder adhering and depositing in the solute storage chamber 34a and the like.

  The solvent supply mechanism 4 includes a flow meter and supplies a predetermined amount of liquid as a solvent to the dissolution pump 1.

  The configuration of the dissolution pump 1 is not particularly limited as long as it can suck and dissolve the primary raw material and the secondary raw material and the circulating dissolved liquid with a single dissolution pump. In the embodiment, as shown in FIG. 2 to FIG. 3, a plurality of rotor blades 13 </ b> A project from the outer periphery of the rotor 13 attached to the drive shaft of the drive mechanism M inside the cylindrical casing 10. The solute and the solvent are sucked into the introduction chamber 15 as primary raw materials from the suction part 11 and stirred, and the solution is discharged from the discharge part 12.

In this case, the casing 10 includes a cylindrical casing body 10A and a front casing 10B and a rear casing 10C disposed on the front side (left side in FIG. 2) and the rear side (right side in FIG. 2) of the casing body 10A. In addition, the casing body 10A is provided with a discharge portion 12 that discharges the dissolved liquid that is dissolved by stirring.
A cylindrical stator 14A is disposed in the front casing 10B so as to be positioned between the rotary blade 13A and the introduction chamber 15, and the throttle channel S is configured by through holes Sa and Sb formed in the stator 14A. Like to do.
The throttle channel S can be constituted by a slit or a nozzle in addition to the through hole.

If necessary, a stator 14B in which a through hole (a slit-like long hole in this embodiment) is formed as the throttle channel S can be disposed on the outer peripheral side of the rotary blade 13A.
Thereby, when passing through a through-hole with respect to a solution, a shear force can be made to act by a rotary blade, and melt | dissolution can be accelerated | stimulated.

Further, a filter funnel-shaped partition plate 16 is fixed to the rotor 13 via a plurality of bosses 16a inside the rotor blade 13A and further inside the stator 14A.
This partition plate 16 is introduced from one suction portion 11A of the suction portion 11 into an introduction chamber 15A (this introduction chamber) into which a solute and a solvent for sucking a primary material composed of a solute and a solvent that are initially mixed in the mixing nozzle 5 are introduced. 15A, in the case of secondary dissolution, the dissolved solution that has been subjected to the primary dissolution stored in the storage means 7 is introduced as a secondary raw material.) And a part of the dissolved solution discharged from the discharge unit 12 However, it circulates through the other suction part 11B and partitions the introduction chamber 15B to be introduced, and the sliding part between the partition plate 16 and the casing 10 has a step-like labyrinth structure, The primary material can be smoothly sucked into the introduction chamber 15A.

Here, since the introduction chamber 15 is divided into the introduction chamber 15A and the introduction chamber 15B, in this embodiment, as shown in FIG. 3, the through holes Sa and Sb formed in the stator 14A are formed. The shape of the through hole Sa facing the introduction chamber 15A is set to a circular shape that prevents the primary material from being clogged, and the through hole Sb facing the introduction chamber 15B is set to an oval shape in which shearing force by the rotating blades easily acts on the solution. I am doing so.
Here, through hole Sa, the shape of Sb can be arbitrarily set according to the primary feedstock and secondary feedstock and the properties of the dissolution liquid circulating like, for example, as the reference example described later, the primary dissolution In the case where the first dissolution pump 1A to be performed and the second dissolution pump 1B to perform the secondary dissolution are configured by separate dissolution pumps, the first dissolution pump 1A and the second dissolution pump 1B are used as a stator. The shapes of the through holes Sa and Sb formed in 14A can be different.

The discharge unit 12 of the dissolution pump 1 is provided with separation means 2 for separating and supplying the solution to the circulation channel 26 and the discharge channel 25 by specific gravity.
In this embodiment, the separating means 2 is arranged such that an introduction pipe 21 connected to the discharge part 12 of the dissolution pump 1 protrudes from the bottom surface of the cylindrical container 20 and is disposed above the cylindrical container 20. 25, a discharge port 22 connected to 25, a circulation port 23 connected to the circulation flow path 26 in the lower portion, and a twist plate 24 for turning the flow of the solution discharged from the introduction pipe 21 at the discharge end of the introduction pipe 21 It arranges and constitutes.
Instead of the torsion plate 24 or together with the torsion plate 24, an agitation blade for agitating the solution discharged from the introduction pipe 21 may be disposed above the discharge end of the introduction pipe 21.
By providing this separation means 2, a solution component having a large specific gravity which is not completely dissolved is separated and supplied to the circulation channel 26, and a solution component having a small specific gravity dissolved is supplied to the discharge channel 25. It is possible to prevent the solution component that is not completely dissolved from being discharged from the discharge flow path 25 and to improve the operation efficiency of the apparatus.

  The closing means 6 makes it possible to selectively close the suction of the primary material composed of the solute and the solvent into the suction portion 11 of the dissolution pump 1. In this embodiment, the closing means 6 is substantially the same as the inner diameter of the flow path. A partition plate having a passage hole of the same diameter is disposed at the tip of the cylinder, and a shutter valve that moves the partition plate perpendicular to the flow path is used.

The closing means 6 can be disposed at any location as long as it can selectively close the suction of the primary material composed of the solute and the solvent into the suction portion 11 of the dissolution pump 1. In the embodiment, a shutter valve is provided between the solute supply mechanism 3 and the mixing nozzle 5, and the suction of the solvent into the suction part 11 of the dissolution pump 1 is closed and opened in the solvent supply path 40. This is performed by the valve 41.
In the present embodiment, in a state in which the suction of the primary raw material is closed, the solution obtained by the primary dissolution stored in the storage means 7 is supplied as the secondary raw material to the supply path 40 which is a solvent supply path. It is configured so that.
Thereby, it is not necessary to separately provide a secondary raw material supply unit in the dissolution pump 1, and the structure of the dissolution pump 1 can be simplified.

The storage means 7 is used for storing the dissolved liquid that has undergone primary dissolution and discharged from the discharge port 22 of the separation means 2 via the discharge flow path 25, and can be stored in any form such as a tank or a hopper. Means can be used.
In this embodiment, the storage means 7 uses a tank 70, connects the discharge flow path 25 to the inlet 71 formed in the upper part of the tank 70, and supplies the secondary raw material to the outlet 72 formed in the lower part. A flow path 44 is connected, and the secondary raw material flow path 44 is connected to a supply path 40 that is a supply part of a solvent via an on-off valve 42.
In addition, the tank 70 is provided with a stirring blade 73 that is rotationally driven by a drive mechanism 74 so that the solution stored in the tank 70 can be stirred.
Further, the tank 70 may be provided with an air release valve (not shown) as necessary to degas bubbles contained in the solution.

The dissolution apparatus A starts the operation of the dissolution pump 1 while supplying the solute and the solvent from the solute supply mechanism 3 and the solvent supply mechanism 4 to the dissolution pump 1 as primary materials.
The solute and the solvent are initially mixed in the mixing nozzle 5 and then introduced into the introduction chamber 15A from the suction portion 11A of the dissolution pump 1.
Then, by passing through the through hole Sa formed in the stator 14A and the through hole formed in the stator 14B disposed on the inner side and the outer side of the rotary blade 13A, the stirring and melting are performed while receiving a shearing action, and the discharge unit 12 It is discharged from.

  The lysate discharged from the discharge part 12 is separated by the separating means 2 and the lysate component having a large specific gravity which is not completely dissolved is supplied from the suction part 11B of the lysis pump 1 to the introduction chamber 15B via the circulation channel 26. By being introduced and passing through the through hole Sb formed in the stator 14A and the through hole formed in the stator 14B, the mixture is stirred and dissolved while being subjected to a shearing action, and discharged from the discharge unit 12, while the dissolution with a small specific gravity is completed. The dissolved solution component is stored in the tank 70 as the storage means 7 through the discharge channel 25.

  When a predetermined amount of the primary raw material is supplied, the closing means 6 closes the suction of the primary raw material made of the solute and the solvent to complete the primary dissolution and perform the primary dissolution stored in the storage means 7. By using the dissolved solution as a secondary material and introducing it into the introduction chamber 15A from the suction part 11A of the dissolution pump 1 in a state where the suction of the primary material is closed by the closing means 6, and operating the dissolution pump 1 in the same manner as the primary dissolution. Secondary dissolution is performed.

In this secondary melting, the efficiency of the melting pump 1 can be improved by closing the suction of the primary raw material and operating the melting pump 1 in a state where the suction of the gas is eliminated, and the introduction chambers 15A and 15B. In a high vacuum state, cavitation is caused in the solution passing through the through holes Sa formed in the stator 14A as the throttle channel S and the through holes formed in the stator 14B, and expansion of bubbles contained in the solution Due to the impact caused by the above, dissolution can be promoted and the microbubbles remaining in the solution can be eliminated.
In addition, since the microbubbles remaining in the solution to be circulated in the suction part 11B can be eliminated, the efficiency of the dissolution pump 1 can be further improved, and even when the solute is a hardly soluble substance, it is semi-dissolved. The substance in the state can be completely dissolved.

In the present embodiment, the solution that has undergone secondary dissolution is temporarily returned to the tank 70 as the storage means 7 via the discharge channel 25, and further to the dissolution pump 1 as necessary. After repeating this circulation, the opening / closing valves 42 and 43 are opened and closed, and then sent to the next step N.
Thereby, it is possible to obtain a high-quality solution that does not leave microbubbles or a semi-dissolved substance in the solution.

Thus, the dissolution apparatus B continuously performs primary dissolution performed while inhaling the primary material composed of the solute and the solvent, and secondary dissolution performed while inhaling the solution obtained by the primary dissolution as the secondary material. To be able to.
Here, the structure of the first dissolution pump 1A and a second dissolution pump 1B includes a dissolution pump 1 dissolution apparatus A of the real施例, it does not necessarily require closure means 6 and the like for closing the intake of primary raw materials It is basically the same except for the points.

In this reference example, the first dissolution pump 1A is composed of one dissolution pump 1A, and the second dissolution pump 1B is composed of two dissolution pumps 1Ba, 1Bb (here, the dissolution pump 1Bb Shows the example in which three dissolution pumps 1A, 1Ba, 1Bb are connected in series. The number of dissolution pumps and the connection method (series connection) In addition, parallel connection can be used in combination.) Can be arbitrarily set according to the properties of the primary material and the secondary material.

Here, in the connection flow path 27 that connects the first dissolution pump 1A and the second dissolution pump 1Ba and the connection flow path 27a that connects the second dissolution pump 1Ba and the second dissolution pump 1Bb, the storage means 8 is provided. To intervene.
The storage means 8 is for temporarily storing the solution, and any type of storage means such as a tank or a hopper can be used.
The storage unit 8 includes a level meter 81 that measures the amount of the stored dissolved solution, and opens and closes the on-off valve 82 by a level signal from the level meter 81 to supply the secondary raw material to the second dissolution pumps 1Ba and 1Bb. As a solution, the solution is supplied.
In addition, the storage means 8 may be provided with an air release valve (not shown) as necessary to degas bubbles contained in the solution.

In the secondary melting performed by operating the second dissolution pumps 1Ba and 1Bb, the dissolution apparatus B is operated by operating the second dissolution pumps 1Ba and 1Bb in a state where gas suction is eliminated. The melting pumps 1Ba and 1Bb can be improved in efficiency, the introduction chambers 15A and 15B are brought into a high vacuum state, and a through hole Sa formed in the stator 14A as the throttle channel S and a through hole formed in the stator 14B are provided. Cavitation is caused in the passing solution, and the expansion of bubbles contained in the solution and the impact generated thereby promote the dissolution and eliminate the microbubbles remaining in the solution. .
In addition, since the microbubbles remaining in the solution to be circulated in the suction part 11B can be eliminated, the efficiency of the dissolution pump 1 can be further improved, and even when the solute is a hardly soluble substance, it is semi-dissolved. The substance in the state can be completely dissolved.
