However, it is not suitable for a stock solution with poor peelability of cake. That is, in the case of using the filter cloth as the filter medium,
The filter cloth is run and the cake is mechanically scraped outside the row of filter plates using a scraper. However, even with this method, it is not possible to remove the cake that has entered the eyes of the filter cloth.

A release sheet is provided above the filter medium so as to cover the filter medium, and the release sheet is allowed to run between the filter plates. As the release sheet to be run between the filter plates, a long strip-shaped release sheet may be arranged so as to sew between the filter plates, and a short release sheet may be provided for each filter plate unit. Then, this may be reciprocated between filter plates. Further, in the case of a cake having a poor peeling property, high pressure air is jetted from the take-out hole of the filtrate.

基づいてこの発明を具体的に説明する。In the present invention, since the cake is not easily attached because the metal filter medium is used and the upper surface of the cake is covered with the release sheet, the generated cake is deposited on the release sheet. Therefore, the filtration is completed, the filter medium is opened, and the release sheet is run, whereby the accumulated cake is transferred to the outside of the filter plate row, and the release sheet is inverted and dropped to be removed at the portion. At this time, a scraper may be used in the case of a cake having poor peelability because it is outside the row of filter plates. Further, when removing the cake described above, the cake generated between the release sheet and the metal filter medium is one that is peeled off together with the cake of the release sheet because it is peeled off from the filter medium because the filter medium is metal. is there. Even in this case, the remaining cake can be completely removed by ejecting high-pressure air from the filtrate outlet provided in the filtration bed on the back surface of the filter medium. Further, in this invention, since the filter plate is horizontally arranged and the filtration chamber is horizontal, the undiluted solution is uniformly supplied to the filtration surface, and a horizontal filtration layer is formed on the filter medium. Therefore, when pressurizing with a diaphragm without the thickness of the undiluted liquid layer in the upper part and the lower part of the filtration chamber being different, as in the conventional vertically formed filtration chamber (horizontal filter),
It is possible to carry out filtration while maintaining a stable cake filtration layer without disturbing the stock solution. The release sheet is made of a synthetic resin material having a good cake releasability, and a scraper or the like is not necessarily required to release the cake from the release sheet. Hereinafter, the present invention will be specifically described with reference to the drawings.
