発安全装置付流動層装置に関する。[Detailed Description of the Invention] [Technical Field] The present invention relates to granulation, coating, mixing, and
The present invention relates to a fluidized bed apparatus for drying, etc., and particularly to a fluidized bed apparatus equipped with an explosion safety device that uses a pulse jet for the bag filter removal mechanism.

く提供されている。
Generally, a fluidized bed apparatus equipped with a bag filter has been conventionally used for granulation, coating, mixing, drying, etc. of powder materials such as medicines, foods, cosmetics, ferrite, toner, etc. In addition, many devices have been provided in which a pulse jet is used as a back filter removal mechanism in such conventional devices.

れており、流動床において起こり易い爆発に際
し、作業者に爆発の被害が及ぶ危険が非常に大き
く、安全上極めて重大な欠点を有していた。 However, in these conventionally known devices, the support seat that attaches the Bacfilter to its storage chamber is made of a material that is difficult to shatter under explosive pressure and melts under the heat of an explosion, such as steel plate. In the event of an explosion, which is likely to occur in a fluidized bed, there is a very high risk of explosion damage to workers, and this has an extremely serious drawback in terms of safety.
そこで、本出願人は特公昭56−44776号公報に
示す爆発安全装置付流動層装置を提供して工業上
効果をあげてきた。 Therefore, the present applicant has provided a fluidized bed apparatus with an explosion safety device as shown in Japanese Patent Publication No. 56-44776, and has achieved industrial results.

れがあつた。 However, even in this device, since the support seat member to which the bag filter is attached has air permeability or is made of an adhesive material, powder and granules adhere to the same part, reducing the product yield. There was a risk that there would be an adverse effect on the composition, or that certain components would selectively adhere when processing multiple types of powder and granules, resulting in changes in the component content. In addition, since the bench lily tube provided to make the backwashing air of the pulse jet more effective while preventing the adhesion of powder and granules to the support seat portion is located within the cylindrical shape of the cylindrical filter cloth,
Pulse air did not act on the filter cloth around it, and there was a risk that powder particles would adhere to that area. Furthermore, since the member that fixes the bag filter to the support seat is also located within the cylinder of the filter cloth, pulse air does not act on the filter cloth around it, and powder particles adhere to that part. There was a risk that the yield of the product would decrease and the content of ingredients in the product would change.
