う問題があった。However, in the above-mentioned prior art, in order to take out a branch pipe from the main pipe of the water pipe, if necessary, from the main pipe, drilling work on this water pipe is required. The cutting work of the running water pipe 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. .
【０００４】また、この穿孔、配管工事は地中で行われ

あり、水質の保障が困難であった。The drilling and piping work is almost always performed underground, and sand and the like may enter the flowing water pipe, making it difficult to ensure water quality.

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 many years, the filter member will be clogged and the flow of the 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.

こる。Further, water is constantly supplied in one direction in the main pipe of the water pipe. However, in a branch pipe branched in a mesh form, backflow occurs depending on the use and supply state of water,
In a flowing water pipe such as a branch pipe, a flow may be generated in both directions. Therefore, if the filter member is simply installed in the water pipe, impurities accumulated and accumulated by the filter member up to that time will flow away from the filter member at the same time as the backflow, and thus the function of the filter may not be performed.

First, a filter member is pivotally supported in the surrounding case.
Forming a partition wall and integrating the backwash mouth with this partition wall
The so as to open a backwashing outlet in a part of the outer circumferential surface of the filter member, is characterized in that the backwashing outlet were passed to the discharge unit through an opening and closing valve by.

A cylindrical filter member 24 that can be rotated together with the upper disk 22 and the lower disk 23 by the operation shaft 21 is pivotally mounted on the central portion of the, and the interior lid 13 is covered from above. Also, both upright portions of the U-shaped partition wall 20 are 2
A vertically separate compartment 26 is formed between the outer surface of the filter member 24 after installation and the inner surface of the surrounding case 2 (FIG. 4).

いった利点がある。In the apparatus for removing contaminants in the water pipe 1 configured as described above, since the surrounding case 2 has a larger passage area than the water pipe 1, the water pipe is substantially enlarged and the flow velocity is increased. Since the water drops rapidly at the enlarged portion, the contaminants T contained in the flowing water flowing through the water pipe 1 sink into the space S. Then, by opening the partition plug 11 of the branch pipe 12, the contaminants T accumulated in a predetermined amount with the passage of time can be discharged to the outside through the branch pipe 12 as shown in FIG. 5.
That is, most of the contaminants T flowing in both directions settle before reaching the filter member 24, and only the other contaminants T adhere to the filter member 24. There is an advantage that it does not occur for a long time.

る。Next, the contaminants that have reached the filter member 24 adhere to the mesh portion of the filter member 24 together with the flow of water, block the flow downstream, and accumulate there. When this contaminant T is left for a long time, the filter member 2
4 deteriorates the flow of the water from the upstream side, thereby lowering the water pressure in the downstream area. Therefore, first, the partition plug 15 which is an on-off valve is opened to discharge water from the branch pipe 16, and as shown in FIGS. Is given a rotation about the operation rod 21.

取り込まれる。On both sides of the filter member 24, two plate pieces 25 and the surrounding case 2 separate the compartments 26.
Is formed, the outer peripheral surface of the filter member 24 to which the contaminants T adhere enters into the compartment 26 due to the rotation of the filter member 24. Since the partition plug 15 is open as described above, a part of the water flows from the inside of the filter member 24 into the compartment 26, and the flow separates the contaminants T attached to the surface of the filter member 24, and the compartment T Is taken in.

い。In this way, the contaminants T taken in by the backwashing action pass through the hole 14 from the compartment 26 and are further discharged from the branch pipe 16 to the outside. This backwashing operation of the filter member 24 is performed periodically after a predetermined period has elapsed,
This may be performed before the water flow reverses as shown by the broken line in FIG.

雑物の流れを阻止できる。Regardless of the flowing direction, the partition plug 15
Is opened and the filter member 24 is simply rotated by the operation shaft 21. Since the surface of the filter member 24 is cleaned by the backwashing operation, the filter member 24 can be moved in the downstream direction without replacing the filter member. The flow of impurities can be prevented.

保守管理が行える。According to the above construction, foreign matter in the water flowing from one direction is trapped on one outer peripheral surface of the cylindrical filter member. Backwashing opening provided in the partition wall positioned on the outer circumferential surface of the filter member by opening the on-off valve is not electrically connected to the discharge portion
Because it can be washed discharging contaminants the filter member surface backwash effect by rotating the filter member. Since the filter member has a cylindrical shape, foreign substances can be trapped even when water flows in either direction, and maintenance of the filter member by backwashing can be performed without replacing the filter member.
