[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contaminant removing device for removing contaminants contained in flowing water flowing in a flowing pipe.

[0002]

2. Description of the Related Art Generally, in running water pipes, for example, ductile cast iron pipes, mortar lining is applied to the inner surface of the pipes to prevent rust, and the quality of water supplied to each household is guaranteed.

[0003]

However, in the above-mentioned conventional technique, the branch pipe is taken out from the upstream side of the water flow pipe as necessary, so that the flow water pipe is bored and the flow water pipe is cut. Construction is done. There was a problem that metal powder was generated in these construction processes, and metal parts were exposed by the drilling and cutting work of the running water pipe, and rust was generated in this part, so these metal powder and rust powder flowed in the running water pipe. .

Most of the drilling and piping work is performed underground, and sand or the like may enter the running water pipe, making it difficult to guarantee water quality.

Therefore, an apparatus equipped with 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 running water in the running water pipe will be hindered. Therefore, it is necessary to regularly replace the filter member. This replacement work has to be carried out by once stopping the running water in the running water pipe and disassembling the device, which is very troublesome.

The present invention has been made by paying attention to such a problem, and it is possible to remove impurities in the running water pipe to ensure the water quality and to perform maintenance work very easily. An object of the present invention is to provide a foreign matter removing device.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a water pipe as a running water pipe, and a substantially cylindrical case 2 composed of upper and lower members is watertightly fitted and fixed to the water pipe 1. The axis of the substantially cylindrical case 2 extends substantially at right angles to the axis of the water pipe 1 and coincides with the through chamber 3 formed in the water pipe 1 by a drilling means such as a drill. A cylindrical filter member 4 is attached to the penetrating chamber 3 so as to block running water in the water pipe 1, and a cylindrical filter member 4 for trapping foreign matters caused by the running water in the water pipe 1. That is, the cylindrical filter member 4 constitutes the foreign matter capturing means.

The filter member 4 is formed in a mesh shape, and has a hole portion 5 on the front surface for receiving impurities, as shown in FIG. An annular support frame 8 for supporting a rotary partition plate 7 of a backwash chamber 6 described later is attached to the peripheral edge of the lower end of the cylindrical filter member 4. As shown in FIG. 1, the filter member 4 is
An annular holding member 9 fixed to the inner wall of the case 2 and a disc-shaped holding member 11 pressed by a lid 10 are fixedly held. The holding member 11 has a seal member 12 on the outer peripheral surface thereof, and the case 2 is sealed by the seal member 12 in a state of being inserted into the case 2.

In the filter member 4, as clearly shown in FIG. 3, central angles extending in the radial direction around the spindle 14 and integrally connected to each other by a boss portion 15 fitted to the spindle 14 are provided. two separators 16 of α,
In a state in which the rotary partition plate 7 is fitted to the boss portion 15 so as to come into contact with the separating plate 16 from below, the rotary partition plate 7 is concentrically rotatable with the cylindrical filter member 4. In this case, a tip member 17 is formed on each of the two separators 16 and has substantially the same height as the filter member 4.

The seal piece 24 shown in FIG. 2 is for separating the inflow side and the outflow side of the filter member 4,
It is in contact with the outer peripheral surface of the filter member 4 over its entire height.

By combining the separator plate 16 and the rotary partition plate 7 which are integrally connected to each other by the boss portion 15 with the filter member 4, that is, the two separator plates 16 and the inner peripheral surface of the filter member 4. Between them, a backwash chamber 6 having a fan-shaped cross section with a central angle α is formed.

The backwash chamber 6 is closed by a holding member 11 and a rotary partition plate 7. Since the rotary partition plate 7 has a discharge hole 18, a through chamber 3 and a discharge chamber 19 are formed. And the discharge chamber 19 is connected to the case bottom wall 20 by a discharge pipe 21 as a drainage part of the embodiment of the present invention and an open / close valve 22 interposed in the discharge pipe 21. It can be arbitrarily opened to (mainly the atmosphere). The discharge chamber 19 is completely separated from the running water region other than the backwash chamber 6 by the rotary partition plate 7 and the holding member 9.

Further, a water turbine device 25 having a first gear 31 and a second gear 32 of the embodiment of the present invention is fixedly mounted on the discharge pipe 21, and the first gear 31 has a central axis thereof. The worm 27 attached to the connecting rod 26 and the worm wheel 28, the rotary partition plate 7 to the discharge chamber 1
The spindle 14 extending through the case 2 and extending to the outside of the case 2 is given a rotary motion. That is, the first gear 31, the second gear 32, the rotation partition plate 7 and the separator 1
6 and 6 are linked so as to interlock with each other to form a linking unit. Further, the water turbine device 25 and the connecting means are covered by the case 13.

In this embodiment, the running water in the water pipe 1 flows from left to right as shown by an arrow P in FIGS. At that time, since the running water flows through the cylindrical filter member 4 from the inner side to the outer side, impurities mixed in the running water are trapped on the inner peripheral surface side of the filter member 4, and gradually there. Deposit on. When the accumulation of impurities progresses to some extent, the filter member 4 is clogged, and eventually a large non-negligible resistance is generated in the water flow in the water pipe 1.
In this case, contaminants can be removed from the filter member 4 by backwashing the filter member 4 in a water-free state.

At the start of backwashing, the on-off valve 22 is first opened. Then, the backwash chamber 6 is opened to the outside (mainly atmospheric pressure). Thereby, in the arc region a of the central angle α of the filter member 4 surrounded by the backwash chamber 6, the relatively high static pressure on the side of the water pipe 1 (that is, the outside) and the side of the backwash chamber 6 (that is, the inside). Since a relatively low external pressure acts, a backwash action occurs based on the pressure difference.

Then, as shown in FIGS. 7 and 8, when the washed water flows from the discharge hole 18 of the backwash chamber 6 into the discharge chamber 19 and further into the discharge pipe 21, the water flow passes through the water wheel device 25. To do. Here, as shown in FIGS. 5 and 6, the water turbine device 25 includes an inflow hole 29 for communicating with the upstream discharge chamber 19 and an outflow hole 30 for communicating with the downstream discharge pipe 21. And a second gear 32 that meshes with the first gear 31 and has a connecting rod 26 parallel to the water flow in a vertical position as a central axis. The first gear 31 and the second gear 32 are configured to rotate by passing through the meshing portion of the gear 31 and the second gear 32.

The rotating force reliably rotates the rotating partition plate 7 and the separating plate 16 via the connecting rod 26, so that the arc region a of the filter member 4 which is subjected to the backwashing action is the entire peripheral surface of the filter member 4. Will automatically move over. In addition, since the gear is composed of two gears, the water flow can be received without waste, so that the rotation efficiency of the gear is increased and the arc region a of the filter member 4 can be reliably moved.

All the contaminants thus deposited on the inner peripheral surface of the filter member 4 are completely removed by the backwashing action and discharged from the discharge pipe 21. Finally, the on-off valve 22
The backwashing action is terminated by closing.

Further, here, as shown in FIGS. 1 and 8,
Spindle 1 extending from the through chamber 3 to the outside of the case 2
A gauge 23 that indicates the position of the backwash chamber in the case 2 is formed at the front end of the case 4. As a result, after cleaning,
It is possible to install the backwash chamber 6 on the downstream side where the resistance of the water flow of the water pipe 1 is less likely to be affected by using the gauge 23 as a guide.

Further, according to the present invention, a suction pump (not shown) is connected to the discharge pipe 21 further downstream of the opening / closing valve, and the water pressure in the case 2 is forcibly reduced, so that the first gear 31 By increasing the rotational force of the second gear 32, the rotation partition plate 7 and the separator plate 16 can be rotated more smoothly.

Although the embodiments have been described above with reference to the drawings, the specific configuration is not limited to the embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Be done.
