[0003] By the way, when an object to be processed such as powder is agitated by such a fluidized bed processing apparatus or a batch type mixing apparatus, the object to be processed such as powder adheres to the container body, and the product quality is reduced. This has been a cause of lowering and stagnation or clogging near the lower discharge of the object. Therefore, some means for removing an object to be processed adhered to the inner wall of the container body have conventionally been proposed or implemented.

For example, a knocker vibrator is used to apply vibration from the outer surface of a rigid container body that is performing a mixing process,
There is a means for peeling and separating an object to be processed. Also, a swingable sleeve is hung on the inner wall surface of the container body as in Japanese Utility Model Publication No. 61-13069 "Powder adhesion prevention device of powder processing machine", and this is vibrated by pressurized air to remove the workpiece. There is a way to drop it. Further, there are means using an air sweeper device for removing powder from the inner surface of the container main body by the blast air, and means using an apparatus such as an air blaster. Further, as described in Japanese Patent Publication No. Hei 8-24801, "Method and Apparatus for Removing Powder", there is a means for forming a container body with a porous filter and blowing pressurized air from the outer surface side.

[0005] However, the above-mentioned means have disadvantages. That is, depending on the means of the knocker vibrator, although vibration is applied to the container body, considering the service life of the machine, the applied vibration is slight, and there is adhesion that cannot be completely removed. Further, in the case of the sleeve system, complication of the mechanism is inevitable, and there are problems such as maintainability and manufacturing cost. Furthermore, the air sweeper and the air blaster have a problem that a large amount of air is used and the operation cost of the apparatus is excessively high.

In other words, the mechanism for preventing the adhesion and stagnation of an object to be treated in the apparatus for treating powdery or granular materials according to the present invention is at least one of a container body in a fluidized bed treatment apparatus or a batch type mixing treatment apparatus. Forming a deformed portion in which a flexible material is applied to the portion, and preventing the object to be processed in the container body from adhering to and staying on the inner surface of the container body by deforming the deformed portion. is there. According to the present invention, since a deformed portion is formed in the container body and a means for vibrating the deformed portion is employed, relatively large vibration can be easily generated. Then, since the adhesion of the object to be treated on the inner wall surface of the container body is eliminated, the operation does not become unstable due to a sudden drop of a relatively large amount of the object. In addition, since there is no sudden drop of such deposits, there is little occurrence of a workpiece that is not heat-treated,
Product quality becomes uniform. Further, when the object to be processed is replaced, contamination is not caused by replacing a flexible material such as a canvas. In addition, since the container body is not air-permeable, gas in the container body does not flow out, and harmful effects of toxic gas and powder can be prevented.
