られる如くになっている。When performing normal filtration operation in a rapid filtration device having the above-mentioned configuration, the liquid to be filtered stored in the liquid to be filtered storage tank 1 is transferred to the filtration tube 2 via the liquid feeding tube 6 by the liquid feeding tube 5. After the substance to be filtered mixed with it is filtered, it is fed into the space above the filter medium 8 inside the filtration chamber 7 and passes through the filter medium 8. The liquid is guided by the pressure of the liquid feed pump 5 through the siphon pipe 11 to the upper space of the filtration chamber 7, that is, the storage tank 9 for the filtered liquid, and is sent to the next process through the overflow port pipe 10 of the storage tank 9.

は槽１４に向って流出する。By the way, if the above-mentioned filtration operation continues for a long period of time, and the filter material 8 becomes clogged due to an increase in the amount of substances filtered and removed from the liquid to be filtered, and it becomes difficult for the liquid to be filtered to pass through the filter medium 8, the filter material 8 becomes clogged. The filtrate flows out from the space above the filter medium 8 through the siphon pipe 12 directly to the external adjustment tank 3 in an unfiltered state. In the adjustment tank 3, as a result of the inflow of a large amount of the liquid to be filtered, the liquid level rises and finally begins to flow out from the overflow port pipe 13 at the upper part toward the tank 4. When the liquid level is detected and the level rises, the liquid level rises. The liquid level gauge switch 15 operates to stop the operation of the liquid feeding pump 5 via the electric circuit 17. As a result, the pressure from the liquid feed pump 5 disappears, and at the same time, the filtered liquid stored in the storage tank 9 at the top of the filtration tube 2 passes through the siphon pipe 11 in the opposite direction to the normal case by its head. The filter material 8 flows into the space below the filter material 8 in the filtration chamber 7, and after the filter material 8 is violently jetted up from below and cleaned, it flows into the adjustment tank 3 together with the washed-off substances to be filtered by the siphon action of the siphon pipe 12, and the overflow port is formed. The receiver also flows out via pipe 13 into tank 14 .

を擁している。After the cleaning action of the filter medium 8 by the liquid to be filtered continues for a while, when the filtered liquid in the storage chamber 9 has completely flowed out, outside air flows into the siphon pipes 11 and 12, and the siphon action is stopped. On the other hand, the liquid to be filtered that has flowed into the adjustment tank 3 also flows out into the receiving tank 4, and the liquid level gradually decreases, and when it finally falls to the position of the drain pipe 14 at the bottom, the low level gauge switch 16 is activated. The stopped liquid feed pump 5 is restarted via the electric circuit 17, and the liquid to be filtered is newly fed from the storage tank 1 to the filtration chamber 7, and normal filtration operation is resumed. Therefore, in this type of rapid filtration device, each time the filter medium 8 becomes noticeably clogged, the process of stopping the filtration operation, cleaning the filter medium 8, and restarting the filtration operation after cleaning is automatically repeated. <Problems to be Solved by the Invention> However, in the conventional rapid filtration apparatus as described above, when cleaning the filter medium 8 inside the filter chamber 7 of the filter cylinder 2, the liquid feed pump 5 At the same time as the storage chamber 9 of the filtration tube 2 is stopped,
The filtered liquid is sprayed from the lower space through the siphon pipe 11 to clean the filter medium 8, and the entire amount in the storage chamber 9 is transferred to the siphon pipe 1 after cleaning the filter medium 8.
2, it flows into the adjustment tank 3, and further from the adjustment tank 3, the flow flows into the tank 4.
It is only when the liquid to be filtered in the adjustment tank 3 that flows out towards the water level that the liquid level in the adjustment tank 3 is lowered and the low liquid level gauge switch 16 is operated can the liquid feed pump 5 be restarted and normal filtration operation can be started. Therefore, it is possible to avoid consuming more filtered liquid and more time than necessary for cleaning the filter medium 8.
This method has the problem of being extremely disadvantageous in terms of efficiency and economy.

場合と同様である。In the rapid filtration device according to the present invention, as illustrated in FIG. 1, a filtration tube 2 includes a filtration chamber 7 having a filter medium 8 therein, and a liquid storage chamber to be filtered separated from each other above the filtration chamber. 9, the space below the filter medium 8 in the filtration chamber 7 and the storage chamber 9 communicate with each other via a siphon pipe 11, and an overflow port pipe 10 is provided at a suitable position in the upper part of the storage chamber 9. The liquid to be filtered storage tank 1 provided outside the filter tube 2 and the filtration chamber 7 communicate with each other through a liquid feed pipe 6 in which a liquid feed cap 5 is provided at an appropriate position along the way. The upper space of the filter medium 8 in the filtration chamber 7 and the adjustment tank 3 provided outside communicate with each other via the siphon pipe 12, and the adjustment chamber 3 has a high liquid level gauge switch 15 and a low liquid level gauge switch 16. and the liquid level when the liquid level flows out from the overflow port pipe 13 at the upper part of the adjustment tank 3 to the tank 4 on the outside, and when the liquid level flows out into the tank 4 from the drain pipe 14 at the lower part, respectively. The liquid level of the liquid is detected and the required electrical operation is performed, and the two liquid dark detection switches 15 and 1
6 is connected to the drive source of the liquid feed pump 5 via an electric circuit 17, and during normal filtration operation, the liquid to be filtered stored in the liquid to be filtered storage tank 1 is fed by the liquid feed pump).
It is fed into the space above the filter medium 8 in the filtration chamber 7 of the filter tube 2 through the pipe 6, and the mixed substances to be filtered are filtered by passing through the filter medium 8, and then from the space below the filter medium 8. The pressure of the liquid feed pump 5 leads the liquid to be filtered through the pipe 11 to the storage chamber and sends it to the next process through the overflow pipe 10, as in the case of conventional rapid filtration equipment. Furthermore, if the filtration operation continues for a long period of time, the filter material becomes clogged due to the increase in the substances to be filtered and removed from the liquid to be filtered, and finally the liquid to be filtered cannot pass through, and the liquid to be filtered becomes clogged. When the liquid flows directly into the adjustment tank 3 through the siphon pipe 12 that communicates the space above the filter medium 8 with the external adjustment tank 3 without being filtered, the rise in the liquid level in the adjustment tank 3 is detected by a high liquid level meter. The switch 15 detects this and stops the liquid feeding siphon 5 via the electric circuit 17, and at the same time as the pressure disappears, the filtered liquid stored in the storage chamber 9 of the filtration tube 2 is transferred to the siphon tube 11 by its head. After that, the backflow flows up from the space below the filter medium 8 in the filtration chamber 7 and washes the filter medium, and then flows into the adjustment tank 3 together with the substances to be filtered washed away by the siphon action of the siphon pipe 12, and overflows. The receiver flows out toward the tank 4 through the mouth pipe 13, and as a result, when the filtered liquid in the storage chamber 9 drains out, outside air enters the siphon pipes 11 and 12. While the siphon phenomenon is stopped, the liquid to be filtered that has flowed into the adjustment tank 3 also flows out toward the receiving tank 4, and when the liquid level drops to the position of the drain pipe at the bottom, the low level gauge switch is turned off. 16 operates to restart the stopped liquid feed pump, and the liquid to be filtered is newly fed from the storage tank 1 into the filter cylinder 2, so that normal filtration operation can be performed. Unlike conventional rapid filtration devices, the process of stopping the filtration operation, cleaning the filter 8, and restarting the filtration operation after cleaning is automatically repeated each time the filter medium 8 becomes severely clogged. The same is true.

る。However, in the rapid filtration device according to the present invention, as illustrated in FIG. The siphon pipe 12 communicates with the highest part of the siphon pipe 12.
In addition, the free end 19 of the return pipe 18 with a small inner diameter is connected to the filter tube 2.
The opening is made at an appropriate position within the filtered liquid to be filtered inside the storage tank 9. Therefore, as described above, when the high liquid level gauge switch 15 of the adjustment tank 4 is activated and the operation of the liquid feed pump 5 is stopped, the liquid to be filtered inside the storage tank 9 flows through the siphon pipe 11 with its head. It then flows into the space below the filter medium 8 in the filtration chamber, blows up the filter medium 8 and cleans it, and then flows into the siphon pipe 1 from the space above the filter medium 8.
While the liquid to be filtered flows out into the adjustment tank 4 due to the siphon action of step 2, the inside of the return pipe 18 is filled with the liquid to be filtered as long as the liquid level is above the open end 19 of the return pipe 18. However, when the liquid to be filtered gradually decreases in volume and its liquid level drops to below the open end 19 of the return pipe 18, the outside air entering from the overflow port pipe 10 of the storage tank 9 flows into the return pipe. It penetrates into the siphon pipe 12 through 18 and stops its siphon action. As a result, after the filter medium has been washed from the storage tank 9, the outflow of the liquid to be filtered toward the adjustment tank 3 is blocked, and the liquid to be filtered that has flowed into the adjustment tank 3 flows out into the external tank 4, and its liquid level When the level drops to the position of the drain pipe 14 of the adjustment tank 3, the low level gauge switch 16 is activated and the electric circuit 1 is activated.
7, the liquid feeder pump 5 is restarted, and normal filtration operation of the rapid filtration device is restarted. Therefore, the filter medium 8 can be cleaned in a short time using the minimum necessary amount of the filtered liquid to be filtered. <Effects of the Invention> As explained above, the present invention comprises a liquid feed pump and a filter cylinder. The liquid to be filtered is sent by the pump from the liquid to be filtered storage tank to the filtration chamber in the filter tube and passes through the filter material to remove mixed substances to be filtered. In a rapid filtration device, the filtrate is introduced into a storage chamber formed in the upper space, and flows out through the overflow pipe and sent to the next process. a device for cleaning the filter medium provided in a filtration chamber inside the filter cylinder with the filtered liquid to be filtered; One end of a return pipe having an inner diameter smaller than that of the siphon pipe is connected to the highest part of the siphon pipe, which is connected to a regulating tank equipped with means for controlling start/stop, and one end of the return pipe is connected to the regulating tank provided with means for controlling start/stop. By opening at an appropriate position below the overflow port side in the storage chamber inside the cylinder, the amount of filtered liquid to be filtered in the storage chamber of the filtration cylinder is removed in an amount necessary for cleaning the filter medium. After the filtrate has flowed out, the siphon action of the siphon pipe is stopped via the return pipe, and further outflow of the filtrate is prevented, which reduces the time required for consumption and cleaning of the filtered filtrate. This has the effect of making the operation of the rapid filtration device more efficient and economical.
