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 filtered liquid 2 by the liquid feed pump 5 via the liquid feed pipe 6. The substance to be filtered is fed into the space above the filter medium 8 inside the filtration chamber 7, and after passing through the filter medium 8, the substance to be filtered mixed with the button is filtered. 5, the liquid is guided through the siphon pipe 11 to the upper space of the filtration chamber 7, that is, the storage tank 9 for filtered liquid to be filtered, and is sent to the next process through the overflow port pipe 10 of the storage tank 9. ing.

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, the filter medium 8 becomes clogged due to an increase in the substances to be 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 liquid to be filtered is directly directed from the upper space of the filter medium 8 through the siphon pipe 12 to the external adjustment tank 3 without being filtered.
It flows out. 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 feed 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 above the filtered liquid 2 passes through the siphon pipe 11 in the opposite direction to the normal case. 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 .

が自動的に反覆されることになる。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, the process of stopping the filtration operation, cleaning the filter 8, and restarting the filtration operation after cleaning is automatically repeated every time the filter medium 8 becomes significantly less clogged. will be done.

する必要があるという問題点を擁している。<Problems to be solved by the invention><However, in the conventional rapid filtration apparatus as described above, the siphon tube 1
When the inner diameter of the filter 2 becomes larger than the inner diameter of the liquid feed pipe 6 to a certain extent, the liquid feed pipe becomes If the liquid feeding bomb 5 of 6 is left as it is, the inside of the siphon pipe 12 will be transferred to the storage tank 1.
Since it is difficult to fill the siphon tube 12 with the liquid to be filtered from the storage tank 9, it is difficult for outside air to enter the inside of the siphon tube 12 and cause a siphon effect. The liquid is introduced into the filtration chamber 7 through the pipe 11, and is sprayed from the bottom of the filter medium 8 for cleaning.Then, the liquid is sent through the siphon pipe 12 into the adjustment tank 3, and as described above, the liquid is discharged through the level gauge switch 15 or 16. Therefore, in the configuration of a conventional rapid filtration device, if the inner diameter of the siphon pipe 12 is approximately equal to the inner diameter of the liquid feed pipe 6, the feed pump 5 cannot be stopped or restarted. Even if there is no problem in exciting the siphon action of the siphon tube 12 with the liquid feed pump provided, in this case, the inner diameter of the siphon tube 12 is small, so the filter medium 8 is washed with the filtered liquid to be filtered. If it takes a long time to clean the siphon pipe 12, and if the inner diameter of the siphon pipe 12 is to be reduced in order to clean it in a short time, the capacity of the liquid feed pump 5 may be increased to excite the siphon phenomenon in the siphon pipe 12. This has the problem that it needs to be increased more than in the normal case.

的とする。The present invention solves the above-mentioned problems of the conventional rapid filtration device, and even if the inner diameter of the siphon pipe 12 that communicates the filtration chamber 7 of the already filtered 2 and the external adjustment tank 3 is changed, the conventional rapid filtration device can be improved. It is an object of the present invention to provide a rapid filtration device in which a siphon action can be excited in a saphon pipe 12 using a liquid feed pump having a capacity comparable to that of a liquid feed pump 5 provided in a liquid feed pipe 6.

装置の場合と同様である。<Embodiment of the Invention> As illustrated in the figure, the filtered 2 is separated from a filtration chamber 7 having a filter medium 8 therein and a liquid storage chamber 9 to be filtered separated from each other above the filtration chamber. 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 upper part of the storage chamber 9. The liquid to be filtered storage tank 1 provided outside the filtered liquid 2 and the filtration chamber 7 communicate with each other through a liquid feed pipe 6 having a liquid feed pump 5 provided at a suitable location midway therebetween, while the filtration chamber 7 The upper space of the filter medium 8 and the adjustment tank 3 provided outside communicate with each other via the siphon pipe 12, and the adjustment chamber 3 is provided with a high liquid level gauge switch 15 and a low liquid level gauge switch 16. The liquid level when the external receiver flows out into the tank 4 from the upper overflow port pipe 13 inside the adjustment tank 3, and the liquid level when the receiver flows out into the tank 4 from the lower drain pipe 14, respectively. and the dual-liquid meter switch 1 is configured to perform the required electrical operation by detecting the
5 and 16 are 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. filtration medium 8 in the filtration chamber 7 of the filter tube 2)
The mixed substance to be filtered is filtered by being sent into the upper space and passing through the filter medium 8, and the liquid to be filtered is passed through the siphon pipe 11 from the space below the filter medium 8 by the pressure of the liquid feed bong 5. It is the same as in the case of a conventional rapid filtration device that it is guided to the storage chamber and sent to the next process through the overflow port pipe 10.Furthermore, if the filtration operation is continued for a long time, the liquid to be filtered is filtered and removed. Due to the increased amount of substances to be filtered, the filter medium becomes clogged and finally becomes unable to allow the liquid to pass through, and the liquid remains unfiltered, leaving the upper space of the filter medium 8 and the external adjustment tank 3. Siphon tube 12 that connects
When the liquid starts to flow directly into the adjustment tank 3, the high liquid level gauge switch 15 detects the rise in the liquid level in the adjustment tank 3 and stops the liquid feed pump 5 via the electric circuit 17, and the pressure increases. At the same time as extinguishing the fire, the filtered liquid stored in the storage chamber 9 of the filter cylinder 2 flows back through the siphon pipe 11 by the head and is blown up from the space below the filter medium 8 in the filtration chamber 7 to clean the filter medium. After that, the filtered substances flow into the adjustment tank 3 together with the substances to be filtered that have been washed away by the siphon action of the siphon pipe 12, and the receiver flows out toward the tank 4 through the overflow pipe 13, resulting in storage. When the filtered liquid in the chamber 9 has completely flowed out, outside air enters the siphon pipes 11 and 12 and the siphon phenomenon is stopped, while the filtered liquid that has flowed into the adjustment tank 3 is also drained into the receiving tank. When the liquid level drops to the level of the drain pipe at the bottom by flowing out toward the drain pipe 4, the low liquid level indicator switch 16 is activated to restart the stopped liquid feeding pump, and newly feed the liquid to be filtered. is fed into the filter cylinder 2 from the storage tank 1, so that normal filtration operation is performed, and each time the filter medium 8 becomes severely clogged, the filtration operation is stopped, the filter medium 8 is washed, Similarly to the conventional rapid filtration apparatus, the restart of the filtration operation after cleaning is automatically repeated.

A siphon pipe 18 that communicates with the siphon pipe 12 and has an inner diameter smaller than that of the liquid feed pipe 6, and a siphon pipe 18 that communicates with the siphon pipe 12 and is also connected to the liquid feed pipe 6 at a position slightly higher than the point where the siphon pipe communicates with the siphon pipe 18. is provided with a siphon tube 19 having a small diameter, and in this case, the free end of the siphon tube 18 opens near the bottom in the adjustment tank 3, and connects to one end of the siphon tube 19 via an ejector 20 near the open end. Therefore, in the rapid filtration device according to the present invention, when the filter medium 8 becomes severely clogged, the liquid to be filtered sent into the filtration chamber 7 by the liquid feed pump 5 is directly passed through the siphon. The liquid flows into the tube 12 and flows out through the siphon tube 18 at the highest point toward the adjustment tank 3, but since the inner diameter of the siphon tube 18 is smaller than the inner diameter of the liquid feed tube 6, it easily causes a siphon effect. At this time, the inside of the siphon tube 19 becomes negative pressure through the ejector 20 due to the flow rate of the liquid to be filtered which flows out from the open end of the siphon tube 18, and therefore the inside of the siphon tube 12 also becomes negative pressure. As a result, the filtered liquid in the storage tank 9 of the filter tube 2 flows into the siphon tube 11. The filter medium 8 is blown up through the space below the filter medium 8 in the filtration chamber 7 for cleaning, and then passed through the siphon pipe 12 to the adjustment tank 3.
It becomes extremely easy to flow into.

Since the siphon action of the siphon pipe 12 can be easily excited without particularly increasing the capacity of the conventional liquid feed pump 5, the filter medium 8 can be washed in a short time with a large amount of the liquid to be filtered at once. become.

。<Effects of the Invention> As explained above, the present invention is comprised of a liquid feed pump and a filtration tube, and the pump sends the liquid to be filtered from the storage tank to the filtration chamber in the filtration tube and passes through the filter medium. The filtered liquid from which mixed substances to be filtered are filtered out is guided by siphon action to the filtered liquid storage chamber formed in the space above the filtration cylinder and flows out through the overflow pipe to the outside for the next step. In the rapid filtration device, the filter is provided for cleaning the filter medium in the filtration chamber (by the filtered liquid stored in the storage chamber of the filtration tube), and the upper side of the filter medium The liquid to be filtered is fed by the liquid feed pump to the highest part of the siphon pipe, which communicates the space with a regulating tank disposed outside the filtration cylinder and equipped with a means for controlling start/stop of the liquid feed pump. One end of each of two siphon tubes having an inner diameter smaller than that of the liquid feed tube that sends the liquid from the filtrate storage tank to the filtration chamber in the filtration cylinder is connected so that the communicating portion of one siphon tube is connected to the communicating portion of the other siphon tube. At the same time, the other end of the siphon tube at the higher position of the communication portion is communicated with the other siphon tube via the ejector, and the other end of the other siphon tube is connected to the other siphon tube through the ejector. K so that it opens into the inside of the adjustment tank.
In particular, the two siphon tubes with small inner diameters can very easily stimulate the siphon action in the siphon tube that communicates the space above the filter medium in the filtration chamber with the adjustment tank. Even in the case of the siphon pipe, which has a smaller inner diameter than the liquid feed pipe, it is possible to generate a siphon effect without particularly increasing the capacity of the liquid feed pump, thereby shortening the cleaning of the filter medium with a large amount of the liquid to be filtered. Since it can be done in a short amount of time, it has a significant economic advantage.
