In the figure, reference numeral 13 is a supply port for the stock solution, 13a is a seal ring at the supply port, and 14 is a support arm for suspending on the guide rail 2. Further, reference numeral 15 denotes a main pipe for supplying purified water to a cleaning device installed around the filter plate, and 15a denotes a nozzle pipe for cleaning the upper surface of the filter plate 3, which is located above the middle between the open filter plates 3, 3. It is provided. 15b is a nozzle pipe for cleaning the middle part of the filter plate, and 15c is a nozzle pipe for cleaning the lower part of the filter plate.These nozzle pipes 15b and 15c are provided on the sides of the filter plate row. Yes, its injection nozzle 16
are facing the left and right filter plates when the plates are opened. Furthermore, Figure 2
In the figure, the symbol S indicates a falling cake.

、除去することができるものである。The cake removing device according to the present invention is constructed as described above, and in order to remove the cake generated in the filtration chamber A, each filter plate is opened and at the same time, high pressure air is introduced into the filter bed 3a. All you have to do is blow air. That is, at the same time as the filtration is completed and the removal of the filtrate is completed, the electromagnetic on-off valve 11 is opened to supply high pressure air from the compressor, and this high pressure air is blown out from the filter bed 3a, thereby removing the release sheet 9.
The cake on the punching metal 8 can be pushed up, peeled off, and removed.

付着して剥離するものである。In this invention, when blowing with high-pressure air, the filter medium is constructed of fine punched metal 8, and a special air supply path (take-out path 10) is provided for each unit filtration bed of the filter medium. Since the outlet is opened in the filter bed 3a, the high-pressure air is dispersed in the liquid collection groove of the filter bed 3a and flows uniformly, without short circuiting, onto the punching metal 8 and the release sheet 9. The cake can be pushed up and peeled off. Note that the cake between the release sheet 9 and the punching metal 8 is peeled off together with the cake on the release sheet 9. At this time, since the punching metal 8 is made of metal, the adhesive force to the metal is smaller than the adhesive force between the cakes, so the cake on the punching metal 8 adheres to the cake on the release sheet 9 and is peeled off. It is something to do.

That is, the pre-purified water from the cleaning pipe 15a can completely remove the cake in the upper seal part of the filter plate and the stock solution supply part where it is difficult to blow high-pressure air, and the pre-purified water from the cleaning pipes 15b and 15c can completely remove the cake from the upper seal part of the filter plate and the supply part of the stock solution, which is difficult to blow with high-pressure air. The cake remaining in the middle and lower parts of the can be completely removed.

In addition to being able to remove the cake by peeling it off, by spraying purified water on the cake that remains on the seal surface etc. during peeling, it can be completely removed. This problem was completely solved. Furthermore, by using a metal material or a synthetic resin material as the filter material, pressure resistance and temperature resistance can be improved, and the versatility of the filter press can be further enhanced.
