Description of the Related Art A filter for collecting powder particles is used in a fluidized bed granulator, but the conventional filter is used in the fluidized bed granulator 1 as shown in FIG. A bag filter 2 made of a material such as Tetoron woven cloth is mounted inside (fluidized bed). In the fluidized bed granulating apparatus 1 as described above, the vent pipe 3 is provided at the back of the bag filter 2, and a large number of vent holes 4 are formed on the entire surface of the vent pipe 3 as shown in FIG. Then, the ventilation pipe 3 is pressed so that the ventilation hole 4 is communicated with the back of the bag filter 2, and the bag filter 2 is repeatedly expanded and compressed by the air intermittently fed from the ventilation pipe 3 to cause powder on the filter surface. Prevents particles from adhering.

の製造の妨げとなっていた。However, since the conventional filter uses a cloth such as a tetron woven cloth, it is difficult to remove and wash the powder and granules in the seams of the cloth. Further, since there is a large amount of the remaining granules attached to the surface of the filter, it is necessary to prepare a dedicated filter for each kind of granules. In addition, since the filter is removed and replaced every time the granulated product is changed, it takes time and effort,
Could not be automated. Furthermore, since air is intermittently fed, the pressure in the fluidized bed is fluctuated, which hinders the production of granulated products having uniform physical properties.

われる。Now, in the fluidized bed granulating apparatus 1 as described above, the raw materials are put into the fluidized bed 10, the slit rotary disk 11 is rotated, and the air supplied from the air supply port 13 is blown up, whereby the granules are prepared. Granulation and coating are performed. The discharge hole 15 is closed during granulation.
The air blown up above the fluidized bed 10 by the blown air is exhausted from the exhaust hole 18 through the filter 5, and at this time, the powder of the granulating agent that has risen up in the fluidized bed 10 is attached around the filter 5 and is exposed to the outside. It doesn't leak. During the above-described granulation, the motor 23 and the motor 24 are operated, the rotating shaft 19 and the screw 22 are rotated, and the jet nozzle 20 is vertically moved while rotating inside the filter 5. When the vertical movement of one filter 5 is completed, the vertical movement of the next filter 5 is started, and when the vertical movement of the fourth filter 5 is completed, the first filter 5 is returned to and this process is repeated. Further, low-pressure (discharge pressure of about 1 kg / cm 2 ) continuous air is discharged from the jet nozzle 20. Thereby, the powder of the granulating agent adhered around the filter 5 is blown off by the air with almost no change in the pressure in the fluidized bed, and the adhesion of the powder is prevented. Thus, even if the adhesion of the powder of the granulating agent around the filter 5 is prevented, the pressure fluctuation in the fluidized bed is reduced and a stable fluidized state is obtained, so that the granulated or coated product having uniform physical properties is obtained. Is obtained and the yield is also improved. When the granulation is completed in this way, the discharge hole 15 is opened to discharge the granulated product. After finishing the granulation as described above,
Next, water is ejected from the jet nozzle 20 to clean the filter 5 from the inside. Further, the motor 29 and the motor 30 are operated to rotate the jet nozzle 26 and the jet nozzle 32 while moving the jet nozzle 20 up and down at the same time as the jet nozzle 20. Also wash at the same time. The pressure of this discharged water is 70 to 100 kg.
It is performed at a high pressure of about / cm 2 . The jet nozzle 26
The inner wall of the fluidized bed 10 is simultaneously washed with water discharged from the fluidized bed 10 and the jet nozzle 32 is directed downward.
Apply water to the bottom of the to wash. The jet nozzles 20 and 26 may be nozzles that can eject in two-dimensional to three-dimensional directions (vertical and diagonal directions). Thus, the cleaning of the filter 5 and the fluidized bed 10 is completed. Hereinafter, the same steps are repeated to granulate and coat the granules.

By using a metal mesh filter, it is possible to remove and wash the powder particles by ejecting air or water. Therefore, the inside of the fluidized bed can be washed without removing the filter. Further, since the metal mesh filter has a shorter drying time than the conventional cloth filter, the fluidized bed apparatus can be efficiently used. Moreover, since the jet fluid adhering to the filter is removed by continuous air, there is little fluctuation in the pressure in the fluidized bed, and uniform granulation or coating can be performed. As described above, the fluidized bed apparatus can be automated.
