A fluid supply / discharge member is provided that has a passage that communicates straight with the undiluted-hole communication passage that penetrates the movable plate, and that communicates with an opening that supplies or discharges the blowing fluid or undiluted solution. According to the above configuration, the passage is not formed inside the movable plate itself as in the related art, but is a member separate from the movable plate and separate from or integrated with the movable plate. Since the passage is formed in the member, the movable plate body can be made thinner than the conventional movable plate body, for example, having a thickness close to the thickness of the filter plate. Further, conventionally, in order to form the above-mentioned passage inside, the movable plate may be thicker than necessary in terms of tightening strength, but in the present invention, the movable plate is thickened beyond the thickness necessary for reinforcement. This eliminates the need, and in this regard, the movable plate can be made thinner. Also, even if the movable plate is formed thin, the passage is formed in a supply / discharge member different from the movable plate main body. And it can be formed accurately. If the passage is formed to have a diameter larger than that of the conventional movable plate, the passage can be easily and easily cleaned. That is, the size and length of the passage can be freely designed and formed without being limited by the size and thickness of the movable plate. Therefore, as compared with the case where the above-described passage is formed in the movable plate as in the conventional case, the length of the passage can be shortened, and the length of the above-mentioned passage is significantly reduced as compared with the case where the passage is formed in the movable plate. Therefore, the work of cleaning the passage can be performed more easily and easily. Further, since the supply / discharge member can be provided at any of the upper, middle and lower portions behind the movable plate, the supply / discharge member can be provided regardless of whether the filter plate is a top feed type, a center feed type, or a bottom feed type. The use member can be provided on the movable plate.

きる。According to the above configuration, when the filter plate is tightened, for example, the stock solution is supplied from the supply flange 8 and the filtration is performed in the respective filter chambers between the filter plates 1 and 1 through the communication passage 9, and then the filter plate is opened. Before the blow, a fluid for blowing such as air or N
2 to supply gas or the like, and supply flange 8 through communication passage 6 through passage 10 of supply / discharge member 7 and passage 6c of movable plate 6.
By discharging more, the stock solution remaining in the communication passage 6 is removed. The supply / discharge member 7 moves integrally with the movable plate 6, and when the filter plate is tightened, the piston rod 1 of the tightening cylinder 12 is moved.
From the movable plate 6 through the supply / discharge member 7 from the movable plate 6
When the filter plate is opened, the movable plate 6 is retracted by the piston rod 12a of the tightening cylinder 12 via the supply / discharge member 7 so that the filter plates 1,.
1 is opened. According to the present embodiment,
The blow passage 10 is not formed inside the movable plate 6 itself as in the related art, but is provided in a member different from the movable plate 6 or in a portion different from the portion that achieves the original function of the movable plate itself. Since the movable plate 6 is formed, the movable plate 6 can be made thinner than the conventional one, for example, close to the thickness of the filter plate 1.

設けることができる。Even if the movable plate 6 is formed thin, the passage 10 is formed in the supply / discharge member 7 different from the movable plate 6,
The passage 10 can be easily and accurately formed if the thickness of the supply / discharge member 7 is formed so as to be easily processed. If the passage 10 is formed to have a diameter larger than that of a conventional movable plate, the passage 10 can be easily and easily cleaned. That is,
The passage 1 is not limited by the size and thickness of the movable plate 6.
The size and length of 0 can be freely designed and formed. Therefore, the length of the passage can be reduced as compared with the case where the above-described passage is formed in the movable plate as in the related art. In particular, in the embodiment of FIGS. Since the length of the passage 10 can be greatly reduced as compared with the case where the passage 10 is formed in the plate 6, the cleaning operation of the passage 10 can be performed more easily and easily. Further, even if the passage is L-shaped and is generally difficult to clean, the supply / discharge member 7 forming the passage 10 is removed from the movable plate 6 and the supply / discharge member 7 is removed.
The cleaning work of the passage 10 can be performed more easily and easily by performing the cleaning work of the passage 10 or by making the supply / discharge member 7 itself disassemblable. Further, since the supply / discharge member 7 can be provided at any of the upper, middle and lower portions behind the movable plate 6, the filter plate 1
Is a top feed type, a center feed type, or a bottom feed type, the supply / discharge member 7 can be provided on the movable plate 6.

おくこともできる。The present invention is not limited to the above embodiment, but can be implemented in various other modes. For example, the blow passage 10 can be used not only for blowing but also as a stock solution supply passage when stock solution is supplied from the movable plate side. The passage 10 of the supply / discharge member 7
Is not limited to the illustrated L-shape, but may be an oblique straight type connecting the flange 11 and the passage 6c of the movable plate 6. In addition, three types of passages are formed in advance at three positions of the upper, middle, and lower portions of the movable plate 6 so as to penetrate the movable plate 6, and only the passage 6c used among the three passages is used. It can be connected to the passage 10 of the supply / discharge member 7 and the other passages can be sealed.
