Definitions
- the present invention relates to a cleaning technique for a filter mounted on a powder processing apparatus, and more particularly, to a cleaning process for a cartridge filter having a pleated structure.
- a granular material processing apparatus such as a fluidized bed granulation coating apparatus that performs processing such as granulation by fluidizing a fine substance by a gas flow is used.
- a gas is supplied for fluidizing the granular material, and a filter for separating the granular material from the exhaust gas is provided.
- the granular material fluidized by the gas flow is filtered by this filter, and only the gas is separated and discharged to the outside of the granular material processing apparatus.
- a filter cloth formed in a pleated shape is often used in order to increase the filtration area.

For this reason, the bubble flow 54 does not hit the filter 53 from the side, and the efficient cleaning process may not be performed only by the bubble flow.
- An object of the present invention is to provide a filter cleaning apparatus and a cleaning method capable of efficiently cleaning a cartridge filter used in a fluidized bed granulator or the like.

- a liquid containing a bubble flow or bubbles along a tangential direction with respect to the filter from a nozzle device installed rotatably around the axis of rotation in the processing vessel and below the filter in the processing vessel The filter is washed while rotating the filter with the bubble flow or the liquid containing bubbles.
- the filter may be a cartridge filter having a pleated structure.
- the filter is installed in the processing container so as to be rotatable about a substantially horizontal rotation axis, and a bubble flow or tangential direction from the nozzle device installed below the filter along the tangential direction to the filter.
- the filter is immersed in the processing container storing the cleaning liquid, and the cleaning process is performed while rotating the filter with the bubble flow or the liquid containing bubbles ejected from the nozzle device attached to the processing container.
