金属粉や錆粉が流水管内を流れるという問題があった。However, in the above-mentioned prior art, in order to take out the branch pipe from the upstream of the water pipe as required, drilling work on this water pipe, and further cutting of the water pipe are required. Construction is performed. In these construction processes, metal powder is generated, and furthermore, a metal portion is exposed during drilling and cutting of the flowing water pipe, and rust is generated in this part, so there was a problem that these metal powder and rust powder flow in the flowing water pipe. .

手間がかかるといった問題があった。[0005] Therefore, an apparatus having a filter member for removing such contaminants in running water has been developed. However, if this device is used for a long time, the filter member will be clogged and the flow of water in the water pipe will be hindered. Therefore, it is necessary to periodically replace the filter member. This replacement operation has to be carried out by once stopping the flowing water in the flowing water pipe and disassembling the device, which is very troublesome.

The flowing water flows from left to right as shown by an arrow P in FIG. 2, for example. At that time, since the flowing water flows through the inside of the cylindrical filter mesh 3 from the inside to the outside, impurities mixed in the flowing water are captured on the inner peripheral surface side of the filter mesh 3 and there. Deposits gradually. Further, impurities having a large specific gravity precipitate and are deposited on the upper surface of the bottom plate 7.

できる。When the accumulation of the impurities progresses to some extent, the filter mesh 3 is clogged, and eventually the water flow in the water pipe 1 generates a large resistance that cannot be ignored. In this case, impurities can be removed from the filter mesh 3 by backwashing the filter member 4 in a water-free state.

洗作用が発生する。That is, at the start of the backwash, the on-off valve 14 is first opened to open the backwash chamber 17 to the outside (mainly atmospheric pressure) via the communication pipe 24 and the discharge pipe 15. Will be. As a result, relatively high static pressure on the water pipe 1 side (ie, outside) and relatively low external pressure on the backwash chamber 17 side (ie, inside) act on the filter mesh 3 near the backwash port 18. Therefore, a backwashing action occurs based on the pressure difference.

Since the backwash mouth 7 of 7 is rotated so as to move over the entire contaminant capturing area of the filter mesh 3, the inner surface of the filter mesh 3 is uniformly washed.

When the rotating blades 9, 19 'and the rotating blade 27 shown in FIG. 4B pass through the discharging hole 9, the discharging hole 9 and the communication hole 28 communicate with each other, and contaminants collected by the rotating blade 27 are collected. Is discharged into the communication pipe 24 and the on-off valve 1 of the discharge pipe 15
It is exhausted to the atmosphere via 4. Also, at this time, the running water from the inside of the backwashing chamber 17 continues.

In addition, impurities accumulated on the upper surface of the bottom plate 7 are completely removed, and finally, the on-off valve 14 is closed to complete the backwashing operation.

に前記回転羽根27の近傍に形成されている。FIGS. 5 and 6 show an apparatus for removing contaminants according to a second embodiment of the present invention. In this apparatus for removing contaminants, as shown in FIG. 5 in particular, the rotating blades 27 are out-of-phase with the
The communication hole 28 is formed near the rotary blade 27 similarly to the first embodiment of the present invention.
【0028】前記回転羽根27は、水流のバランスを保

いる。また、排出管15の排出孔9は、図5、6におい
ては流水に対して下流側に形成されている。The rotary blade 27 has the same outer shape as the backwashing chamber 17 in order to maintain the balance of the water flow. 5 and 6, the discharge hole 9 of the discharge pipe 15 is formed on the downstream side with respect to flowing water.
【0029】このように構成されたフィルター部材4が

流域に位置する時に連通されるように配設されている。In the foreign matter removing apparatus using the filter member 4 configured as described above, the foreign matter is removed by rotating the backwashing chamber 17 similarly to the foreign matter removing apparatus of the embodiment of the present invention. However, as shown in FIG.
The communication hole 28 and the discharge hole 9 are arranged so as to communicate with each other when the backwash chamber 17 is located in the upstream area of the water pipe 1.
【0030】すなわち、連通孔28と排出孔9との連通

る。That is, by the communication between the communication hole 28 and the discharge hole 9, the flowing water in the filter mesh 3 is simultaneously transmitted from the communication portion between the communication hole 28 and the discharge hole 9 and the backwash port 18 into the communication pipe 28. Will be discharged. At this point, the suction force of the backwash mouth 18 drops to about half of the normal level,
However, since it is located in the upstream area of the water pipe 1 in which the amount of trapped contaminants on the inner peripheral surface of the filter mesh 3 is relatively small, there is no effect on the backwashing, and the inner peripheral surface of the filter mesh 3 is captured. Impurities will be relatively uniformly removed.

め、保守作業が極めて簡素化される。By opening the on-off valve and rotating the separator through the rotating shaft, water on the downstream side of the filter mesh flows into the backwashing chamber, and the entire peripheral surface of the filter mesh is backwashed. At the same time, the impurities settling in the discharge section formed under the filter mesh are collected by the rotating blades, and when communicating with the discharge pipe connected to the backwashing chamber and the discharge section at a fixed cycle, an external valve is appropriately provided through the on-off valve. The maintenance work is greatly simplified.
