Description

  The present invention relates to a granulation cooling apparatus including a granulation unit that binds fine particles to form large particles and a cooling unit that cools the formed granulated product to a low temperature.

As a typical granulation method of a granular material, a fluid granulation method, a stirring granulation method, and the like are known.
Patent Document 1 describes a pressure swing granulation method obtained by improving the fluid granulation method. The metal powder as a material is mixed with wax (paraffin) and filled on a fluidized plate to form a powder layer.
The powder layer is subjected to a crushing process in which compressed air is flowed upward and crushed, a fluidizing process in which hot air is blown upward and fluidized, and a compacting process in which compressed air is flowed downward and consolidated. Granulation is described.

Patent Document 2 describes a stirring granulation method and a stirring granulation apparatus that recycles a thermoplastic synthetic resin.
That is, a film-like or fibrous thermoplastic synthetic resin material is pulverized into flakes, and then thermally shrunk by stirring heat generated by high-speed stirring, and granulated. The synthetic resin material is rounded by semi-gelling the surface by mutual frictional heat.

  This granulator includes a stirring granulator and a cooling mixer. The stirring granulator includes a stirring blade that is rotated at a high speed by a vertical rotating shaft in a vertical cylindrical container. In many cases, the inner shape of the container has the same height and diameter, or the height is larger than the diameter. This container has a jacket and can indirectly heat the inside of the container with steam or the like.

  The cooling mixer includes a stirring blade that is rotated at a low speed by a vertical rotating shaft in a vertical cylindrical container. The internal shape of the container is formed such that the height is smaller than the diameter and the bottom surface is wide. This container is provided with a jacket, and the granulated product can be indirectly cooled by cooling water or the like.

The cooling treatment of the granulated product is performed for the purpose of increasing the strength of the formed granulated product, eliminating adhesion between the granulated products to improve fluidity, and preventing alteration of components.
However, when a wax is used as a binder, the granulated product may become very fragile during cooling.

  In other words, until the binder is cooled to a temperature close to room temperature, the binding force of the binder that binds the primary particles is very weak, and the granulated material is destroyed and formed even if it is rotated at a low speed by stirring of the cooling mixer. The particle size distribution may not be maintained.

FIG. 1 shows an outline of a granulation cooling device 100 of the present invention.
The granulation cooling apparatus 100 includes a granulation unit 200 that combines fine particles to form large particles, and a cooling unit 300 that lowers the temperature of the granulated product formed by the granulation unit 200.

  The granulation unit 200 has a configuration in the case of an agitation granulator, and has a rotary shaft 221 rotated by an electric motor 292 in a vertical cylindrical container 211, and a rotary shaft fixed to the rotary shaft 221 and rotated. A blade 222 and an upper blade 223 are provided.

The container 211 is provided with a jacket 212, and a heat medium such as water vapor or cooling water can be passed through the jacket 211 to indirectly heat or cool the interior of the container 211.
An upper part of the container 211 is provided with a supply port 218 for introducing a processed material, and a lower part is provided with a discharge port 219 whose valve is opened and closed by a cylinder 291.

In the granulating unit 200, powder can be processed by batch processing (batch processing), and fine particles can be combined to form a large granulated product.
Materials such as powder and binder to be processed are introduced from the supply port 218 and stirred by the rotation of the lower blade 222 and the upper blade 223.

Since it is a batch process, various conditions for the granulation process need to be determined in advance by a test. In the test, changes in the internal temperature of the container 211, changes in required power of the electric motor 292, and the like are measured, and various conditions are determined with reference to these measured values.
For example, the relationship between the rotation speed and time is determined, and it is determined that the rotation speed is changed in the middle. Part of the material may be added during the process. Heating or cooling from the jacket 212 is performed as necessary.

The inside of the container 211 is often at atmospheric pressure, but may be in a reduced pressure state due to water evaporation and the like.
In order to prevent oxidation of the processed product, an inert gas such as argon or nitrogen can be introduced into the container 211 for processing. At this time, in order to maintain an inert atmosphere, the inside of the container 211 may be in a pressurized state.

When the granulation process is completed, the valve of the discharge port 219 is opened, and the granulated material is discharged to the cooling unit 300 while the lower blade 222 and the upper blade 223 are gently rotated.
The granulation cooling apparatus 100 of the present invention includes a cooling unit 300, and is characterized in that the granulated product formed by the granulation unit 200 can be cooled without being destroyed here.
Several specific configuration examples of the cooling unit 300 will be described.

The cooling unit 300 illustrated in FIG. 2 is an example of a specific configuration.
The cooling unit 300 includes an inverted conical storage tank 351 that can store a predetermined amount of granulated material and a so-called rotary valve, and can discharge the granulated material at a predetermined speed. A discharge unit 360 is provided.

The granulated product from the granulating unit 200 is fed into the storage tank 351 from the supply port 358.
The storage amount of the granulated material in the storage unit 350 is preferably an amount of one batch or more in the granulation unit 200. In the storage tank 351, the granulated product can be indirectly cooled in a substantially stationary state by flowing cooling water or the like through the jacket 352.
In addition to the jacket 352, the cooling capacity can be increased by providing a cooling coil or the like inside the storage tank 351.

The discharge unit 360 includes a connection pipe 371 connected to the storage tank 351.
In the cylindrical connecting pipe 371, the granulated materials are sequentially moved in one direction downward without being mixed with each other. For this reason, the granulated material can be sequentially cooled by flowing cooling water or the like through the jacket 372.
That is, the temperature of the processed material in the connection pipe 371 becomes lower as it goes downward.

  The discharge unit 360 includes a horizontal cylindrical tubular body 361 whose both ends are closed, a rotating shaft 381 that rotates inside the tubular body 361, and a rotational shaft 381 that is fixed to the rotating shaft 381 and that surrounds the inside of the tubular body 361 in the circumferential direction A plurality of partition plates 382 are provided.

  These configurations are so-called rotary valve configurations. That is, the internal space of the cylindrical body 361 is partitioned by the partition plate 382, and a plurality of partition chambers 383 are formed in the circumferential direction. When the rotating shaft 381 is stopped, the flow of the granulated material is stopped by the partition plate 382, and the rotating shaft 381 rotates to sequentially discharge the granulated material filled in the partition chamber 383 downward. can do.

When each compartment 383 is positioned above the cylindrical body 361, it receives the granulated material from the connection pipe 371, moves downward by rotation, and granulates toward the discharge port 369 below the cylindrical body 361. Things will be discharged.
Therefore, when the rotating shaft 381 is rotated at a constant speed, the granulated material can be discharged at a substantially constant speed.

With such a configuration, the granulated product formed in the granulating unit 200 can be appropriately cooled in the cooling unit 300.
That is, in the storage unit 350, the granulated product can be cooled in a state close to a stationary state.
Moreover, in the discharge part 360, it is possible to carry out the sequential movement which moves the flow of a granulated material in one direction, and a granulated material can be cooled sequentially.

And the temperature sensor 375 can be attached in the connection pipe | tube 371, the temperature of the granulated material to pass can be monitored, or discharge | emission of a granulated material can be restrict | limited.
That is, it can be confirmed that the temperature is sufficiently low and the granulated material is strong, and can pass through the tubular body 361 and can be discharged from the discharge port 369.

A cooling unit 400 illustrated in FIG. 3 is another example of a specific configuration that replaces the cooling unit 300.
The cooling unit 400 includes a vertical cylindrical storage tank 451 and is formed with a storage unit 450 capable of storing a predetermined amount of granulated material and a vertical cylindrical tubular body 461, and is formed at a predetermined speed. A discharge part 460 capable of discharging the particles is provided.

The granulated product from the granulating unit 200 is fed into the storage tank 451 from the supply port 458.
The storage amount of the granulated material in the storage unit 450 is preferably an amount of one batch or more in the granulation unit 200. In the storage tank 451, the granulated product can be indirectly cooled in a substantially stationary state by flowing cooling water or the like through the jacket 452.
In addition to the jacket 452, the cooling capacity can be increased by providing a cooling coil or the like inside the storage tank 451.

  The discharge unit 460 is fixed around the rotary disk 485, a rotating shaft 481 that rotates inside the cylindrical body 461, a rotating disk 485 that is fixed to the rotating shaft 481, and the rotating disk 485. And a plurality of partition plates 482 that partition the inside of the cylindrical body 461 in the circumferential direction.

The cylindrical body 461 is open at the upper end to communicate with the lower end of the storage tank 451, and the lower end is closed by a lower fixing plate 466 having an opening 467. And like the storage tank 451, the jacket 462 can be provided and the inside can be cooled.
The rotating disk 485 and the partition plate 482 rotate close to the lower fixed plate 466. The partition plate 482 forms a plurality of partition chambers 483 by partitioning a ring-shaped space formed between the inner periphery of the lower portion of the cylindrical body 461 and the outer periphery of the rotating disk 485 in the circumferential direction. Yes.

  The rotating disk 485 is located directly below the storage tank 451 and supports the granulated material in the storage tank 451 as if it were a bottom plate of the storage tank 451. That is, the granulated material charged into the storage tank 451 from the supply port 458 flows into the cylindrical body 461. Then, it extends around the upper side of the rotating disk 485 and is introduced into the plurality of compartments 483.

  In order to discharge the granulated material at a constant speed, an upper fixing plate 465 is provided above the compartment 483. The upper fixing plate 465 is positioned so as to cover the opening 467 and cover only a part of the partition plate 482. On the other hand, the lower fixing plate 466 is positioned so as to cover the entire partition plate 482 from below, and is entirely closed except for the opening 467.

The compartment 483 is sequentially moved to the position where the opening 467 is located by the rotation thereof, and the granulated material filled therein is discharged from the discharge port 469 through the opening 467.
Since the upper portion of the compartment 483 that discharges the granulated material is covered with the upper fixing plate 465, the granulated material does not flow into the chamber during the discharging. And while passing through the opening 467, the compartment 483 discharges all the granulated material and becomes empty.

By leaving the upper fixing plate 465, the granulated product flows into the empty compartment 483. The compartment 483 into which the granulated material has flowed is immediately filled, and the granulated material in the compartment 483 is in a substantially stationary state until the compartment 483 is full and next approaches the opening 467.
The granulated material filled in the compartment 483 is sequentially moved along with the rotation of the rotating shaft 481 and is sequentially cooled by the jacket 462 of the cylindrical body 461. That is, the temperature of the processed material that is filled and rotated in the plurality of compartments 483 becomes lower as it is closer to the opening 467 (closer to the opening 467).

Therefore, the granulated product formed in the granulating unit 200 can be appropriately cooled in the cooling unit 400.
That is, in the storage unit 450, the granulated product can be cooled in a state close to a stationary state.
Moreover, in the discharge part 460, it is possible to carry out the sequential movement which moves the flow of a granulated material to one direction, and a granulated material can be cooled sequentially.

And the temperature sensor 455 can be attached in the storage tank 451, the temperature of the granulated material to pass can be monitored, or discharge | emission of a granulated material can be restrict | limited.
That is, it can be confirmed that the temperature is sufficiently low and the granulated material is strong, so that it passes through the tubular body 461 and is discharged from the discharge port 469.

A cooling unit 500 shown in FIG. 4 is another example of a specific configuration that replaces the cooling unit 300.
The cooling unit 500 includes a vertical cylindrical storage tank 551 and a storage unit 550 that can store a predetermined amount of granulated material, and two vertical cylindrical bodies (an upper cylindrical body 571 and a lower cylindrical body). And a discharge portion 560 that is formed together with the shaped body 561) and can discharge the granulated material at a predetermined speed.
The opened upper end of the upper cylindrical body 571 is connected to the opened lower end of the storage tank 551 and communicates with each other. As will be described later, the lower cylindrical body 561 can be omitted together with the internal structure.

The granulated product from the granulating unit 200 is fed into the storage tank 551 from the supply port 558.
The storage amount of the granulated material in the storage unit 550 is preferably an amount of one batch or more in the granulation unit 200. In the storage tank 551, the granulated product can be indirectly cooled in a substantially stationary state by flowing cooling water or the like through the jacket 552.
In addition to the jacket 552, the cooling capacity can be increased by providing a cooling coil or the like inside the storage tank 551.

The cooling water can flow from the inside of the rotating shaft 581 to the inside of the lower blade body 582, the upper blade body 583, and the rotating body 588 to cool them.

  The granulated material charged into the storage tank 551 from the supply port 558 is placed on the upper fixing plate 576 in the upper cylindrical body 571. And since there exists the rotary body 588, the granulated material will be located on the upper fixed board 576 in the state brought near to the surrounding wall side of the upper cylindrical body 571. FIG.

  The opening 577 of the upper fixing plate 576 is located near the rotation shaft 581. Moreover, when the upper blade body 583 is rotated in the direction of the arrow according to the shape shown by the arrow BB, the granulated material can be scraped toward the center from the peripheral wall side. And the granulated material scraped by one upper blade body 583 is not mixed with the granulated material scraped by another upper blade body 583.

  For this reason, the granulated product moves sequentially in one direction by the upper blade body 583. At the same time, the granulated material is sequentially cooled by the upper fixing plate 576, the upper blade body 583, and the rotating body 588. That is, the granulated material having the lowest temperature among the granulated materials placed on the upper fixing plate 576 moves from the opening 577 to the lower cylindrical body 561.

In the lower cylindrical body 561, the granulated product from the upper cylindrical body 571 is introduced from the opening 577 near the rotating shaft 581.
The opening 567 of the lower fixing plate 566 is located near the peripheral wall of the lower cylindrical body 561. Moreover, when the lower blade body 582 rotates in the direction of the arrow according to the shape shown by the CC arrow, the granulated material can be scraped toward the outer periphery from the center.

  For this reason, the granulated material is sequentially moved in one direction by the lower blade body 582. At the same time, the granulated material is sequentially cooled by the lower fixing plate 566 and the lower blade body 582. That is, the granulated material having the lowest temperature among the granulated materials placed on the lower fixing plate 566 is discharged from the opening 567 to the discharge port 569.

  In the cooling unit 500, two cylindrical bodies, that is, the upper cylindrical body 571 and the lower cylindrical body 561 are used in order to improve the cooling performance. be able to. That is, it can be set as the simple form which abbreviate | omitted the lower cylindrical body 561, the lower blade | wing body 582, etc.

As a result, in the cooling unit 500, the granulated product formed in the granulating unit 200 can be appropriately cooled.
That is, in the storage unit 550, the granulated product can be cooled in a state close to a stationary state.
Moreover, in the discharge part 560, it is possible to carry out the sequential movement which moves the flow of a granulated material to one direction, and a granulated material can be cooled sequentially.

And the temperature sensor 555 can be attached in the storage tank 551, the temperature of the granulated material to pass can be monitored, or discharge | emission of a granulated material can be restrict | limited.
That is, it is confirmed that the temperature is sufficiently low and the granulated product is strong, so that it passes through the upper cylindrical body 571 and the lower cylindrical body 561 and is discharged from the discharge port 569. can do.
