まで不可能とされていた。Since the conventional multi-stage filtration device is constructed as described above, when the stock solution to be filtered is a highly viscous liquid or a viscous liquid, the filter medium 2 is a filter plate. The seal portion consisting of the first gasket 5 and the supporting member 4 such as punching metal are attached. Therefore, when the filter medium 2 is discharged, the filter medium 2 may suddenly peel off and the solid content 8 may be scattered around, or the chuck 6 may come off the filter medium 2 when the filter medium is moved, and the filter medium 2 may be further damaged. However, there is a problem in that the automatic discharge of the filter medium is hindered or it becomes impossible to discharge the filter medium. Therefore, it has been impossible to automatically exchange the filter medium for viscous liquid filtration.

構成される。Further, as shown in FIG. 3, in order to facilitate the handling of the anti-adhesion material 10, it is preferable that a metal frame 13 is provided around the periphery of the anti-adhesion material 10 and is fastened with screws 14. Further, in order to facilitate the attachment of the adhesion preventing material 10 to the filter plate 1, as shown in FIG. 4, a mounting frame is provided on two opposite sides thereof, and in one example, one of the mounting frames 15a is substantially L-shaped.
The other side 15b is formed in a U shape. On the other hand, on the filter plate 1 side, a locking frame 16a that can be fitted to the mounting frame 15a and a locking frame 16b that receives the mounting frame 15b are provided facing each other, and are inserted and slid (to the right in FIG. 4). ) Is configured to be attached with one touch.

よい。In this apparatus, the attachment of the anti-adhesion material 10 prevents the filter material 2 from adhering to it and thus facilitates its discharge. However, in order to facilitate the discharge of the filter material 2 after completion of the filtration, the end of the filter material 2 is removed. It is preferable to provide a lifting mechanism 18 that slightly raises each chuck 6 that grips a portion, and as shown in FIG. 6, the lifting mechanism 18 is constituted by an air cylinder in one example. The air cylinders may be provided individually on the chucks 6 on both sides, but may be provided in common.

Play a role. It is needless to say that the lifting mechanism 18 may be composed of another mechanism, and for example, a screw mechanism or a rack and pinion mechanism operated by an electric motor may be used.

Filtration is performed with the filter plate 1 clamped, and since the portion 12 of the anti-adhesion material 10 on the filtration surface is permeable, the stock solution passes through the anti-adhesion material 10 and the support member 4 and is filtered without any problem. . The stock solution is subjected to solid-liquid separation, and the solid content 8 is deposited on the filter medium 2.

The filter plate 1 is raised to release the filter medium 2, and the discharge device 7 is operated to move the filter medium 2 together with the chuck 6 to the discharge position. At this time, even if the stock solution is a highly viscous solution, the filter medium 2 is appropriately adhered to the filter plate 1 and the support member 4 by the anti-adhesion material 10, or even if there is adherence, it is weakly adhered. . The discharge of the filter medium 2 is automatically performed by a suitable controller. If the lifting mechanism 18 slightly raises one end of the filter medium 2 together with the chuck 6 before discharging the filter medium 2, the filter medium 2 can be discharged more smoothly.

ことによって、異物による傷も軽減される。Another feature of this filter is that a metal gasket 5a is used as the gasket 5 to improve the seal performance of the seal portion. In one example, even if a pressure of 5 kg / square cm is applied, no leakage occurs. That's what I did. Especially in the case of a metal gasket, there is a drawback that if the seal surface is inadvertently pinched with foreign matter, the seal surface will be damaged and it will be difficult to repair it, and if the filter plate is replaced, it will be expensive. However, in the present invention, by sandwiching the anti-adhesion material 10 together with the filter material 2, scratches due to foreign matter can be reduced.

り、そのような問題を解決している。Further, as shown in FIG. 7, preferably, the metal gasket 5a is detachably attached to the filter plate 1 by the bolt 19 to facilitate the exchange thereof. Therefore, even if the seal surface of the metal gasket 5a is damaged, the metal gasket 5a can be easily replaced, so that excellent sealability can be easily maintained. Conventionally, it can withstand only low pressure,
A liquid receiver was required to receive the leaked liquid, or it was necessary to collect the leaked liquid by making a double seal structure and sucking a vacuum between them to obtain the leaked liquid. Solving the problem.
