It is pushed out by the supplied stock solution and taken out of the machine from the filter frame at the end. On the other hand, the filtrate filtered and separated by the metal mesh flows down the filtration bed of each filter plate, flows down into the liquid collecting tube of the filtrate, and is taken out of the machine. In the concentration operation of the stock solution as described above, in the present invention, since the metal mesh is used as the filter medium, it is difficult to clog, and even if it is clogged, it is possible to carry out backwashing or chemical cleaning with an acid, etc. The clogging can be cleared. Also, when cleaning and regenerating the surface of the metal mesh (flow surface of raw water),
As mentioned above, by adding a simple structure that only provides a bypass in the raw water supply circuit, the raw water can be made to flow in the supply channel alternately in the forward and reverse directions. The clogging material can be washed away by the stock solution supplied from the opposite direction and can be easily removed. Furthermore, the device according to the present invention has a small and simple structure in which filter plates and filter frames are alternately laminated, and there is almost no part that operates in the device by simply supplying the undiluted solution for operation, and it can be released for a long time. The automatic operation is possible, and the initial and running costs are cheaper than conventional products. Hereinafter, the present invention will be specifically described with reference to the drawings.

The concentrated stock solution is separated and concentrated by the metal mesh 9, and the water content of the concentrated stock solution is separated by the metal mesh 9 even while rising in the filter frame 1 of the concentration block B of the next stage. The liquid content is also separated while flowing down, and the concentrated stock solution is obtained from the filter frame 1 at the final stage in the liquid tank 5. On the other hand, the filtrate separated from the undiluted solution flows down the filtration bed 1 a of each filter plate 1 and is collected in the filtrate tank 7 via the take-out path 1 b and the filtrate pipe 6.

洗浄ができるのは勿論である。That is, according to the present invention, by flowing the stock solution in the filter frame 1, the water content is separated by the metal mesh 9 and the concentrated stock solution is continuously obtained from the end portion thereof. Since the filter medium for use is the metal mesh 9, the filter medium is less likely to be clogged and has strength as compared with a conventional filter medium such as a filter cloth. Then, even if it is clogged, it can be easily washed and regenerated by backwashing with a high-pressure fluid, and even if the clogged material is solidified, the filter medium is the metal mesh 9, so this can be removed using a chemical solution or the like. It can be melted and easily removed and regenerated. Needless to say, so-called mounting cleaning can be performed without disassembling the concentrating device when regenerating the filter medium.

とができるものである。When regenerating the above-mentioned filter medium, the concentration operation is stopped, but in the present invention, the continuous concentration operation is carried out only by changing the flow of the stock solution to prevent clogging of the filter medium. Is also possible. That is, as shown in FIG. 5, the exhaust pipe 4 is provided with a bypass 4a and is connected to the inlet pipe A1, the exhaust pipe 4 and the bypass 4a are provided with switching valves V1 and V2, respectively, and the inlet pipe A1 is provided with a branch passage 12 Are installed in the inlet pipe A1 and the branch passage 12, and the switching valve V
3 and V4 are provided, and by operating the switching valves V1 to V4, the stock solution flows through the inlet pipe A1, the blocks A to C of the concentrator and the discharge pipe 4 to the liquid tank 5 (forward flow), and the bypass 4.
a, discharge pipe 4, concentrator block C to A, supply pipe A1
, And can be switched to the flow (backflow) to the liquid tank 5 via the branch pipe 12. By switching the flow of the undiluted solution in this way, the undiluted solution flows from the opposite direction to the foreign matter that stagnates in the flow path and the foreign matter that clogging the eyes of the metal mesh 9. It is possible to flush the stock solution to smooth the flow of the stock solution, prevent the blockage of the flow path and the clogging of the metal mesh 9, and to perform the continuous concentration operation. The operation of the switching valves V1 to V4 for switching the flow of the stock solution described above can be automatically performed using a solenoid valve.
