Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing impurities contained in running water flowing through a water pipe.

[0002]

2. Description of the Related Art Generally, in a flowing water pipe, for example, a ductile cast iron pipe or the like, a mortar lining is provided on an inner surface of the pipe to prevent rust, so that the quality of water supplied to each household is guaranteed.

[0003]

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. .

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.

[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.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and removes foreign substances in the water pipe to ensure the quality of the water and to perform maintenance work extremely easily. An object of the present invention is to provide an apparatus for removing contaminants.

[0007]

A case that covers a part of the water pipe is divided into a through chamber and a discharge chamber by a rotating partition plate.
The drainage chamber is provided with a drainage part that allows water to flow into the atmosphere and an on-off valve, and a filter is fixed in the penetration chamber, and a separating plate that is in contact with the filter on the inner circumference is fixed to the rotating partition plate,
A backwashing room is constituted by the filter, the rotating partition plate, and the separator, and the backwashing room and the discharge chamber communicate with each other through a hole, a water wheel device is provided in the drainage portion, and the rotating partition plate and the water wheel device are provided. Are connected by linking means.

[0008]

By opening the on-off valve connected to the discharge chamber, water on the downstream side of the filter flows into the backwash chamber, and the filter is backwashed.
Furthermore, it is discharged to the atmosphere through an on-off valve. At that time, the water turbine device provided in the drainage section is rotated by the flow of the wash water discharged, and the rotation force rotates the rotating partition plate and the separator plate through the linking means, so that the entire circumference of the filter is rotated. The surface is automatically cleaned.

[0009]

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 fitted and fixed to the water pipe 1 in a watertight manner. The axis of the substantially cylindrical case 2 extends substantially perpendicularly 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 that is attached to the penetration chamber 3 so as to block flowing water in the water pipe 1 and catches foreign substances caused by the flowing water in the water pipe 1 is arranged. 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 5 for receiving contaminants on the front surface as shown in FIG. On the periphery of the lower end of the cylindrical filter member 4, an annular bearing frame 8 for supporting a rotating partition plate 7 of the backwashing chamber 6, which will be described later, is mounted. As shown in FIG. 1, the filter member 4
An annular holding member 9 fixed to the inner wall of the case 2 and a disk-shaped holding member 11 pressed by the lid 10 are immovably 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 while being inserted into the case 2.

In the filter member 4, as shown clearly in FIG. 3, central angles extending radially around the spindle 14 and integrally connected to each other by a boss 15 fitted on the spindle 14. two separators 16 of α,
The rotatable partition plate 7 is fitted to the boss portion 15 so as to abut against the separator plate 16 from below, and is rotatably disposed concentrically 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 from each other.
It is in contact with the outer peripheral surface of the filter member 4 over its entire height.

Further, the separating plate 16 and the rotating partition plate 7 integrally connected to each other by the boss portion 15 are combined with the filter member 4, that is, the two separating plates 16 and the inner peripheral surface of the filter member 4 are combined. A backwash chamber 6 having a sectoral cross-section with a central angle α is formed between them.

The backwashing chamber 6 is closed by the holding member 11 and the rotary partitioning plate 7. However, since the rotary partitioning plate 7 is formed with a discharge hole 18, the penetration chamber 3 and the discharge chamber 19 are formed. The discharge chamber 19 is connected to a case bottom wall 20 by a discharge pipe 21 serving 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 freely opened to (mainly the atmosphere). The discharge chamber 19 is completely separated from the flowing water area other than the backwash chamber 6 by the rotating partition plate 7 and the holding member 9.

A water turbine 25 having a first gear 31 and a second gear 32 according to the embodiment of the present invention is fixed to the discharge pipe 21. The first gear 31 has a central axis. The worm 27 mounted on the connecting rod 26 and the worm wheel 28 form the discharge chamber 1 from the rotating partition plate 7.
9 to give a rotary movement to a spindle 14 extending outside the case 2. That is, the first gear 31, the second gear 32, the rotary partition plate 7 and the separator plate 1
6 are linked so as to interlock with each other to form linking means. 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 this time, since the flowing water flows through the cylindrical filter member 4 from the inside to the outside, impurities mixed in the flowing water are captured on the inner peripheral surface side of the filter member 4 and gradually there. Deposited on When the accumulation of the impurities progresses to some extent, the filter member 4 is clogged, and eventually the water flow in the water pipe 1 generates a large resistance that cannot be ignored.
In this case, it is possible to remove impurities 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 backwashing chamber 6 is opened to the outside (mainly atmospheric pressure). Accordingly, the relatively high static pressure on the water pipe 1 side (i.e., the outside) and the relatively high static pressure on the backwash chamber 6 side (i.e., the inside) exist in the arc region a having the center angle α of the filter member 4 surrounded by the backwash chamber 6. Since a relatively low external pressure acts, a backwash action occurs based on the pressure difference.

As shown in FIGS. 7 and 8, when the washed water flows from the discharge hole 18 of the backwash chamber 6 to the discharge chamber 19 and further to the discharge pipe 21, the water flow passes through the water wheel device 25. I do. Here, as shown in FIGS. 5 and 6, the water turbine device 25 has 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. The interior is composed of a first gear 31 having a connecting shaft 26 as a central axis parallel to the water flow in a vertical position, and a second gear 32 meshing with the first gear 31. The first gear 31 and the second gear 32 are configured to rotate through a meshing portion between the gear 31 and the second gear 32.

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

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

As shown in FIGS. 1 and 8,
Spindle 1 extending from case 2 to outside of case 2
A gauge 23 indicating the position of the backwashing chamber in the case 2 is formed at the tip of 4. Thereby, after washing,
Using the gauge 23 as a guide, the backwashing room 6 can be installed on the downstream side where the resistance of the water flow of the water pipe 1 is less likely.

According to the present invention, a suction pump (not shown) is connected to the discharge pipe 21 further downstream of the on-off valve, and the water pressure in the case 2 is forcibly reduced. , The rotational force of the second gear 32 can be increased, and the rotating partition plate 7 and the separator 16 can be rotated more smoothly.

Although the embodiment has been described with reference to the drawings, the specific configuration is not limited to the embodiment, and any changes or additions without departing from the gist of the present invention are included in the present invention. It is.

[0025]

In the apparatus for removing contaminants in a water pipe according to the present invention, by opening an on-off valve connected to the discharge chamber, water on the downstream side of the filter flows into the backwashing chamber, and the reverse of the filter. Washing is performed, and the washing water is drained from the backwashing room,
Furthermore, it is discharged to the atmosphere through an on-off valve. At that time, the water turbine device provided in the drainage section is rotated by the flow of the flushing water discharged, and the rotating force rotates the rotating partition plate and the separator plate through the linking means, so that the entire periphery of the filter is rotated. The surface is automatically cleaned. Therefore, in the uninterrupted water state, without replacing the filter member,
Since the backwashing chamber is automatically rotated simply by opening the on-off valve, the effect of easily removing the foreign substances trapped by the filter member can be obtained.
