という要請がある。``Problems to be Solved by the Invention'' However, the above-mentioned cap for supplying the stock solution is located at the entrance to the narrow overchamber between the plates, and when the plates are closed, high pressure is applied, so the strength of the cap is not sufficient. On the other hand, a wide passageway is required from above for supplying the stock solution. That is, there is a problem in that it is difficult to ensure strength due to the structure, and on the other hand, there is a requirement that the stock solution can be supplied quickly and that the stock solution containing impurities does not become clogged.

This was done by focusing on the following points, and first, assuming the case where the nozzle, which would be an obstacle to supplying the stock solution, was eliminated,
This invention was developed by considering how to smoothly fill the gap between the pair of cloths in this state with the stock solution. This invention will be explained below.The gist of the invention is that a pair of cloths is stretched between parallel plates that can be opened and closed, and the undiluted solution is filled between the pair of cloths. In the filter press,
At least one of the cloths is provided with a through hole that communicates with the stock solution supply path provided with a plate, and a hole is provided around the through hole that protrudes in the opening/closing direction of the plate, so that under normal conditions, the space between the left and right plates is A pressing piece with elastic force is attached to maintain the distance between the left and right cloths, which is longer than the width of the overchamber.

ある。"Function" That is, in this invention, instead of the base, an elastic material for maintaining the distance between the pair of cloths is provided on the cloth, and by configuring as described above, when the plate is closed, The pair of left and right cloths are pressed against each other by the spacing-maintaining elastic pieces and pressed against the liquid supply plate, thereby making it possible to secure a supply path for the stock solution to the pair of plates. With conventional caps, the cap itself poses an obstacle to the supply of raw liquid, as well as the rail properties between the cap and the plate, the tightening force when the plate is closed, and the powerful squeezing force when squeezing with a diaphragm. However, with this invention, it is only necessary to seal between the cloth and the plate, and the sealing force increases as the plates are closed and the cloth is compressed. , the sealing force becomes stronger. In addition, the above-mentioned elastic material has an extremely simple structure compared to the cap, for example,
If a coil spring or the like is used, the supply path for the stock solution can be made several times wider than that of conventional products.
以下、図面に基づいてこの発明を具体的に説明

着するようなこともないものである。 In the device configured in this way, when the plate 1 is closed to form the over-chamber 3, the pressing pieces 7 provided on the cloth 2 abut against the washers 6 of the cloth 2 facing each other, and the through-holes of the cloth 2 are brought into contact with each other. 5 is pressed against the stock solution supply port 4 of the plate 1 to seal the space between the cloth 2 and the plate 1. Next, when an undiluted solution is supplied into the overchamber 3 configured with a closed plate, the cloth 2 is pressed against the plate 1 by the pressure of the undiluted solution, and the above-mentioned gap is further sealed, forming a sealed overflow chamber. Room 3
can be formed. At this time, there is only a slight pressing piece 7 in the passage of the concentrate at the part where it exits the supply port 4, and compared to the conventional cap, it is possible to secure a much wider passage and to quickly supply the concentrate. is possible, and there is no clogging.
Next, when the filtration is completed in this manner, the cake in the filtration chamber 3 is peeled off and removed by opening the plate 1, and the cake in the stock solution supply port is also removed by the pressing pieces 7 separating from each other. It naturally decomposes and peels off, and unlike conventional caps, it does not get stuck in the supply port.
