When compressed air from the compressed air supply means 1 6 is blown in, as shown by the one-dot chain line arrow, the gas-liquid mixed fluid from the second explosive cleaning circuit 1 4 passes through the third switching valve 1 3 to the reservoir 1 From the second switching valve-5 to the water storage part 1. The water supply pipe 6a is washed by the back-flow agitating action of the gas-liquid mixed fluid. When this second explosion cleaning circuit 14 is used to backflush the water supply line 6 a from the third switching valve 1 3 of the water supply line 6 a to the water storage unit 1, the pump 2 and other switching Valves and on / off valves are inoperative.

The first switching valve 3, the second switching valve 5, the third switching valve 1 3, the fighting valve 8, 1 1.15 are preferably motorized valves that are actuated by signals from the control unit (not shown). The circuit is configured to be competed by remote control by a signal from the control unit.

The casing 4 of the filter 4 is a description of the water circuit. (1) It has an upper port 4a connected to the switching valve 3 via a pipe line and a lower port 4b connected to the second switching valve 5 via a pipe line. Mouth 4 b simple casing 1 7 Filtering filter 1 8 is fixed in the transverse direction. The filter 18 is preferably constructed by integrally superposing the filter cloth 18 b on the upper surface of the strong fine mesh 18 a.

The pipe line extending from the upper opening 4a into the filter 4 has the tip end portion preferably arranged upward, and the water in the purification circuit blows upward in the filter 4 to the filter filter 1 8 surface. Make sure water is evenly distributed.

A rotary shaft 19 extending vertically through the center of the filter 18 in the vertical direction inside the casing 17 is rotatably supported by the base frame 20 and the support frame 21 in the filter 4. At the same time, a rotary cleaning frame body 23 is fixed to the tip end side of the rotary shaft 19 projecting upward from the filtration filter 18.

The support frame 2 1 holds the filtration filter 1 8 horizontally with respect to the water pressure. The support frame 2 1 is composed of a radiation frame through which water can pass. In the embodiment shown in the figure, the rotation shaft 1 9 is passed through. It is integrally connected to the flange of the central through hole of the filtration filter 1 8 via the support sleeve 2 1 ′.

The rotary cleaning frame 23 is formed by planting the brush 2 2 below the radiation arm fixed to the rotary shaft 19, and the tip of the brush 2 2 is placed on the upper surface of the filter 18. It is arranged so as to come into contact.

The rotary shaft 19 has a rotary vane member 24 fixed to a shaft body below the filtration filter 18 and the support frame 21 so as to face the filtration filter 18 in parallel.

Thus, as shown in FIG. 8, the filter 4 used in the present invention uses the backflow water pressure at the time of opening the backwash circuit of the water circuit to alternately rotate the rotating blade members 24, as indicated by the circular arrows. (2) By rotating in reverse, the clogging of the upper surface of the filtration filter 18 is removed by the brush 2 2 of the rotary cleaning frame 23 rotating forward and reverse. As a result, the inside of the filter 4 is efficiently cleaned by forward and reverse stirring backflow water from the lower part by the rotating blade member 24, and impurities removed from the filter 18 are converted into backwash water. It is blown upward and drained from the upper entrance 4a.
