がなく、腐食を防止することができる。When one filter 8 is backwashed, the protrusion 27
Since the filters 8 rotate and move, the remaining filters 8 are also sequentially backwashed. Note that even if the valve body 18 rotates once, if the differential pressure remains below a predetermined pressure that is lower than the set pressure, backwashing is continued. When the differential pressure drops below the predetermined pressure, the on-off valve 26 is closed and backwashing is stopped. Note that when the liquid has a high viscosity such as oil, steam is supplied from the steam supply nozzle 12 into the body 6 to heat the cylindrical casing 7 to keep the viscosity of the liquid low. Further, the drain water accumulated in the body 6 is discharged from a drain nozzle 13 provided on the lower plate 5. In this way, since the drain nozzle 13 is provided on the lower plate 5, compared to the conventional one provided at the lower part of the body 6, drain water does not remain in the body 6, and corrosion is prevented. can do.

By opening the rJ closing valve and rotating the valve body, liquid can be supplied to multiple filters at once, and by opening the opening/closing valve, the filters can be backwashed one by one. Even if there are a plurality of filters, the rotary valve 111Il is sufficient, and there is no need to provide a three-way switching valve for each filter as in the conventional case, which is very economical. In addition, since the liquid extraction pipe is directly attached to the horizontal plate, unlike the conventional method where it is installed on the cover body, it is extremely easy to remove the cover body during maintenance and inspection (there is no need to remove the liquid extraction pipe). In addition, there is no need to provide a drain port in the liquid extraction chamber (the liquid extraction pipe serves as a drain).
