Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a granulation/coating apparatus, and particularly to a granulation/coating apparatus that can perform granulation, coating, mixing, drying, etc. of powder particles with high productivity.

Generally used in medicines, foods, powder metallurgy materials, catalysts, ferrites, ceramics, detergents, cosmetics, dyes, pigments, etc.
Granulation of powder and granules used in toner, etc.

Various types of mechanical equipment have traditionally been used for coating, mixing, drying, etc.

As one such conventional device, a structure has been proposed in which a wire mesh is provided at the bottom of the granulation cylinder and rotating blades are provided at the top of the wire mesh. However, in this conventional structure, the granules are crushed between the rotary blade and the wire gauze, making it impossible to form them into spheres, and the coating is also damaged, making it unsuitable for granulation coating. Another disadvantage is that powder leaks from the wire mesh.

Further, a structure in which a wire mesh is provided at the lower part of the granulation 1h and a rotating disk is provided at the upper part of the wire mesh is disclosed in JP-A-54-62978 and JP-A-56-133024. However, although the conventional device allows granulation coating, the granules may get between the rotating disk and the wire mesh.
There is a problem in that the rotation of the rotating disk causes the material to rub against the wire mesh and be crushed. In addition, this conventional device 6- also has the disadvantage that powder leaks from the wire mesh, and
There are disadvantages in that it is difficult to control the bulk density of the toughened material, only granules with a vertical negative can be produced, and the particle size distribution is uneven. Furthermore, this conventional device has a problem in that it has low biological properties.

Also, Special Publication No. 46-22544 and Special Publication No. 47-4
No. 7794 discloses a centrifugal rotation operation in which the bottom of the container is formed of a rotating disk, and the rotation of this rotating disk and the action of slit air blown from a gap between the rotating disk and the container wall are performed. A structure is disclosed that performs coaching using the following methods. However, this conventional apparatus is basically aimed at coating, and even when applied to granulation operations, the productivity is low and it is unsuitable for rice production, which is a serious drawback.

Another problem is that although this conventional apparatus can form heavy spherical granules, it is not suitable for light granules.

The purpose of the present invention is to add to the problems of the prior art, to arbitrarily control the bulk density, hardness, particle size, etc. of granules, and to obtain high-quality granules with good fertility. The purpose of the present invention is to provide a granulation coating device that can perform the following steps.

To achieve this objective, the granulation coating device according to the present invention includes rotating plates that rotate in a substantially horizontal direction around their respective rotational axes at independent directions and speeds in the body, and an agitation mechanism above the rotating plates. The granular material is granulated and coated by the combined rotational action of the rotary plate and the stirring member.

Hereinafter, the present invention will be explained in accordance with the actual example shown in the drawings.

These gases are initially blown out in common by an air supply fan 26 shown in FIG. 1 and purified via a filter 28 in an air supply duct 27.
Next, after being heated or cooled to a desired temperature in the heat exchanger 29, the air is supplied to the bottom of the air supply duct 27. The front NL gas passage 24, 25 is partitioned into a slit gas passage 31 and a gas passage 32 to the ventilation section 18 by a partition wall 30 connected to the annular partition wall (19). These slit gas passages 31 and gas passages 32 communicate with the aforementioned slit gas passages 24 and gas passages 25, respectively,
Each has a separate slit gas supply passage and ventilation section 1.

Further, in the vicinity of each of the gas passages 31 and 32, there is a slit gas flow rate adjustment valve 33 for independently and variably adjusting the flow rate of the slit gas or the gas to the Iq gas section 18, and a gas flow control valve 33 for independently adjusting the flow rate of the gas to the Iq gas section 18. A box 34 is provided. By independently controlling these flow control valves 33 and 34, various flow patterns can be obtained by the two gas flows injected into the granulation tube 1 through the slit 16 or the vent 18. can.

On the other hand, as illustrated in FIG. 4, the agitating blade 6 in this embodiment has three melodic claw-shaped agitating elements 36 disposed on the lower side of the boss 35 at intervals of approximately 120 degrees from each other. The structure is designed to increase the grain effect. Further, the stirring blade 6 is connected to the rotating shaft 11 as shown by the broken line in FIG.
The purge gas supplied through the πa air 31 having a shape D'i and -a is sniffed out from the lower surface 1lIII of the boss 35 and is injected into the gap between the rotating shaft 11 and the rotating disk 5. It is designed to prevent particles from getting caught.

frozen, the stirring blade 6 near the bottom of the granulation cylinder 1 of this example

On the other hand, the spray gun 41 and //1 are provided with a nozzle 43 for supplying the powder raw material into the granulation layer in the granulation cylinder 1 at the transfer point 1 of the granulation 1h1 at the same height. There is.

Further, in the upper part of the granulation cylinder 1, a bag filter 44 and a jet nozzle 45 for jet cleaning that continuously removes and dissolves dust etc. adhering to the bag filter 44 using high pressure gas pulses are arranged. , granulation m
An exhaust duct 46 is connected to the top side of the granulation layer 1 to exhaust the exhaust gas from the granulation layer to the outside of the system through a bag filter 44. Furthermore, a hinge-type lid 47 is attached to the top wall of the granulation cylinder l so that it can be opened and closed.

In addition, the front 6 bug filter 44 and the jet nozzle 4
5 can be omitted or replaced with a cyclone.

Next, the operation of this embodiment will be explained.

First, a predetermined amount of powdered raw material is supplied into the granulation cylinder 1 from the raw material input port 2.

On the other hand, the periphery of the rotating disk 5 at the bottom of the granulation cylinder 1 and the granulation cylinder l
The lift mechanism ■4 opens the slit 16 between the inclined surface 17a of the annular protrusion 17 of the body part by a fixed dimension of 7Ji.
With the quotient of the rotating disk 5 set to a predetermined value, the rotating disk 5 is rotated by the motor 8. In that case, at the beginning of the granulation operation, the gas flow regulator should be slightly opened.
The slit gas flow rate adjustment valve 33 is opened by a predetermined amount, and the gas from the air supply fan 26 is introduced into the granulation cylinder 1 through the slit 16.
%.

Thereafter, the stirring blade 6 is rotated by the motor 12 via the belt 13 and the rotating shaft 11 in the same or opposite direction as the rotating disk 5 at a desired speed, thereby stirring the powder material being granulated or coated. On the other hand, the binder liquid or coating liquid, which is pumped from one of the spray guns 41 or 42 or from the circular cylinder ζ liquid tank 38 with a bong 39, 40, is poured into or above the granulation layer. That guy, Gas Sudancho Acupuncture 34 Complete I
It is opened to a fixed amount, and gas is ejected from the rotating disk 50 and the ventilation part 8. Also, if necessary, the granular raw material can be supplied from the nozzle 43 into the granulation layer only to the extent necessary. Exhaust from the granulation layer in the granulation cylinder 1 is carried out through an exhaust duct 46K.
Then, the bag filter 44 is discharged from #≠ to the outside of the thread.

In the granulation coating apparatus of this embodiment, in addition to the combined rotational operation of the rotating disk 5 and the stirring blade 6, a combination vC of the slit gas passing through the slit 16 and the gas passing through the ventilation section 18 is created. The powder and granules are subjected to centrifugal transfer and stirring and mixing, and a cyclical flow pattern in which they rise by the gas flow and fall by their own weight creates a uniform lAtAt dynamic state with no channeling or bubbling, resulting in granulation. The optimum bulk density, hardness [
Alternatively, products with good particle size distribution etc. can be manufactured with high productivity. According to Kyafufu, according to the Honjitsu IAIr example, it is possible to granulate everything from soft and textured products to hard and sticky products, and it is also possible to granulate not only spherical particles but also columnar pellets, for example. It can also be used satisfactorily for coating crystalline powders, etc.

The product after granulation and coating can be quickly discharged from the discharge chute 3 due to the synergistic effect of the rotating blades 5 and stirring blades 6.

In particular, in this embodiment, the rotational direction and speed of the rotating disk 5 and the stirring blade 6 and the 'bfC river of the two gas flows can be controlled by 5J, so that in addition to improving the productivity, the characteristics of the product can also be improved. 7
It is possible to selectively change it to a wider width depending on the user's wishes.

As a first example, the rotational speed of the rotating disk 5 is reduced, the rotating disk 5 and the stirring blade 6 are rotated in the same direction, and the gas passing through the porous portion 18 of the rotating disk 5 is When the flow rate of the slit gas is increased and the flow rate of the slit gas passing through the slit 16 is decreased, the powder and granules are blown upward from the center of the granulation tube 1 and flowed in a flow pattern in which they are moved down by their own weight toward the periphery. , small bulk granules can be obtained.

As a second example, the stirring blade 6 is rotated at a higher speed in the same direction with respect to the rotating disk 5 (/), the flow rate of gas passing through the ventilation part 18 is reduced, and the flow rate of the slit gas is increased. In this case, the powder flows in a flow pattern in which it is blown up along the inner wall surface of the granulation cylinder l and falls from the top to the center under its own weight, resulting in a hard granule with a large bulk density and an almost spherical shape. Obtained.

Moreover, centrifugal force is increased by the stirring blades 6, and the granulation speed can be increased.

As a third example, the rotation speed of the rotating disk 5 and the stirring blade 60,
When the flow rate of the gas passing through the ventilation part 18 and the flow rate of the slit gas are set to be between the first example and the second example, the flow rate between the first example and the second example is adjusted according to the installation. Volume '6f
I! A granulated product having hardness and hardness is produced.

As a fourth example, if the rotational direction of the rotating disk 5 and the stirring blade 6 is aligned, the slit gas is made thicker, and the glazing of the gas passing through the ventilation tube 18 is made smaller, the powder and granules are in the granulation tube 1. A centrifugal rolling type flow pattern is obtained that is pressed against the inner wall surface, and granules with a large bulk density and close to the spherical shape of Koga are produced.

Note that in this example, granulation and coaching can be performed as desired under various conditions other than those described above.
In this example, a wide range of granulation and coating operations such as agglomeration granulation, far-Ib animal granulation, and mixing are possible.

In addition, in this example, before the granulation coating operation, the rotating disk 5 is lowered and the gap size of The spray gun 42 above the granulation layer is rotated at high speed.
By spraying a binder liquid or a coat binder liquid in an amount corresponding to several inches of moisture per the amount of powder and granules, it is possible to humidify and mix the 'a' granules before granulation and coating. This humidification mixing operation scratches the surface of the powder and granules, so
Not only does it have the effect of increasing the speed of granulation and coaching during granulation and coaching, but it also reduces the dissipation of fine powder from the granulation layer, improving the uniformity of the ingredients in the granulated product. obtained, granulation IIX) 1 inside V (there is no peace of mind to install a bag filter, and instead of 7, a simple cyclone (not shown in Figure 2) (1- installed outside the granulation cylinder l, and the cyclone By being able to adopt a method of recycling the thinned powder and granules again, it is possible to obtain an economically inexpensive and infant granulation coating device.

Furthermore, in the case of powders and granules with high specific gravity such as ceramics, powder metallurgy materials, and ferrite, once the fluidization state was unavoidably stopped, it was impossible to restart it, but in this example, stirring By starting the rotation of the wing a6 together with the rotating disk 5, even in such a case, it is easy to restart and kill.

FIG. 5 is a partial sectional view showing another embodiment of the granulation coating apparatus hood according to the present invention.

In this embodiment, the rotary disk 5a has a simple disk-like structure, as clearly shown in FIG. 6, and is not provided with the ventilation section 18 as in the previous embodiment. Further, the side wall opening 11 of the body portion of the granulating cylinder 1 near the periphery of the rotating disk 5a is formed as an inclined surface 1a that is inclined inward at every diagonal downward angle. By moving the rotary disk 5a up and down with the lift machine 1'J114, the tUJ gap dimension of the knot 16 can be adjusted to 79 degrees. Furthermore, Vζ, the stirring blade 6a of this embodiment
has a diameter smaller than the diameter 11 of the rotating disk 5a.

Also in the embodiment shown in FIG. 5, the rotating disk 5a and the stirring blade 6
Due to the rotating operation of a and the thinness of the slit scum passing through the slit 16, a high quality granulated coated product can be obtained with high productivity.

The embodiment shown in Fig. 7 is suitable when it is desired to increase the flow rate of gas passing through the ventilation part 8, and is suitable for granulation of powder or granules with a large degree of density or a large amount of binder liquid, and is suitable for granulated products. The dehydrating and drying effects of coaching products are compounded.

The embodiment shown in FIG. 8 shows a stirring blade 6b having baffles 50 radially protruding from each other at intervals of approximately 120 degrees on its upper surface. The stirring blade 6b may have a smaller diameter than the rotating disk 5 shown by the two-dot line in FIG. 8, or may have approximately the same diameter as the rotating disk 5. This embodiment is suitable for, for example, placing seed particles as a core material and adding powder and binder liquid to the seed particles to make particles close to spheres, and allows for efficient transfer granulation. Can be done.

In the embodiment shown in FIG. 9, the stirring blade 6C has a disk portion 51 with a slightly small diameter and an abbreviated scraper 52. Three scrapers 52 are provided at an angle of approximately 120 degrees to each other, and their upright portions remove powder particles adhering to the inner wall surface V of the granulation cylinder 1. Therefore, this embodiment is suitable, for example, for centrifugal transfer of V-shaped particles with strong aggregation and layering properties.

In addition, the scraper b2 is shown in FIG. 10 (f stirring blade 6d
It is also possible to provide only the scraper 52 on the 1lli wall of the boss 35b instead of uniaxially with the disk as shown in FIG.

Note that the present invention is not limited to the previous Hd embodiment, and various other modifications are easily possible. For example, instead of the rotating disk, a polygonal, substantially disk-shaped rotating plate may be used, and the structure of the stirring blade may also be other than the above embodiments. It is also possible to provide it at the lower end of a rotating shaft that hangs down from the upper part of the granulation cylinder coaxially with the rotating shaft of the rotating disk.
