Abstract

PURPOSE:To provide the device removing impurities in a flowing water pipe to ensure the quality of water and capable of performing maintenance work in an extremely simple manner. CONSTITUTION:By opening the opening and closing valve 32 connected to a discharge chamber 17, the water on the downstream side of a filter mesh 35 begins to flow in a backwashing chamber 14 and a partition plate 16 is rotated through a rotary shaft to backwash the entire inner peripheral surface of the filter mesh 35. At the same time, impurities are also settled on the partition plate 9 positioned on the inner lower surface of the filter mesh 35 but, since a piercing chamber 3 and a discharge chamber 17 communicate at a definite cycle through the discharge hole formed to the inner lower part of the filter mesh 35, the settled impurities are also appropriately discharged to the outside through the opening and closing valve 32.

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 partition plate. The discharge chamber is provided with an on-off valve capable of discharging water into the atmosphere. At least a portion of a cylindrical filter mesh is fixed in the room, and a backwashing room composed of a separator meshed with a rotating shaft and an inner peripheral surface of the filter mesh communicates with the discharge chamber. The removal device is characterized in that a discharge means is provided so as to communicate the through chamber and the discharge chamber at regular intervals through a discharge hole formed in a lower partition plate in the filter mesh.

[0008]

By opening the on-off valve connected to the discharge chamber, the water on the downstream side of the filter mesh starts flowing into the backwashing chamber, and the separator is rotated through the rotating shaft, so that the entire inside of the filter mesh is opened. The peripheral surface is backwashed. At the same time, impurities also settle on the partition plate located on the lower surface inside the filter mesh, but through the discharge hole formed in the lower part inside the filter mesh, the through chamber and the discharge chamber communicate with a fixed cycle, The settled impurities are also discharged to the outside via an on-off valve as appropriate.

The members 6 are inserted so as to be supported, respectively, and the case 2 is sealed so that the lid 12 presses the sealing member 6 from above.

In the filter member 4, there is formed a backwashing chamber 14 rotatable around a spindle 13 passing through the communication hole 7 of the partition plate 9. The backwashing chamber 14 has two separators 16 and 16 ′ formed so that the backwash mouths 15 and 15 ′ open to the inner peripheral surface of the filter mesh 35.
And a bottom plate 19 having a communication hole 18 formed in the lower part of the through chamber 3, a sealing plate 20 for sealing the back of the separators 16 and 16 ′, and an upper end of the separators 16 and 16 ′. It is sealed by the inner lid 21 that is in contact.

A spindle 13 is penetrated through mounting rings 22 and 23 formed on the inner lid 21 and the sealing plate 20, and the spindle 13 is attached to the mounting rings 22 and 23 and the bolt 2
It is fixed at 4. A communication cylinder 25 is formed on the side of the discharge chamber 17 of the communication hole 18 formed in the bottom plate 19.
It is inserted into the communication hole 7 of the partition plate 9,
15 ′ is connected to the discharge chamber 17 via the communication hole 18.

The spindle 13 is provided in the case 2 in the discharge chamber 17.
The spindle 13 is supported by a recess 26 formed in the bottom wall, and a rotating plate 27 is mounted on the spindle 13. The spindle 13 extending further upward penetrates the lid 12 and extends outside the case 2.

The rotary plate 27 is pivotally mounted on the spindle 13 in a positional relationship in contact with an opening surface of a discharge tube 28 fixedly provided on the discharge chamber side of the discharge hole 8 of the partition plate 9. A communication hole 29 is formed at a predetermined position of the rotating plate 27,
It is formed so as to rotate with the rotation of the rotary plate 27 and to coincide with the discharge cylinder 28 at a constant cycle. Further, a plurality of holes 30 are also formed in the outer peripheral surface near the spindle 13 penetrating the center, and the flowing water discharged from the communication tube 25 is passed downward.

The filter member 4 configured as described above
Is fitted into the case 2 so that the inside of the case 2 is partitioned into the through chamber 3 and the discharge chamber 17 by the partition plate 9 and the support frame 10. The discharge chamber 17 has a discharge pipe 31 connected to the bottom wall of the case 2 and an on-off valve 32 interposed in the discharge pipe 31.
And can be arbitrarily opened to the outside. In addition,
The seal piece 33 shown in FIG. 3 is for isolating the inflow side and the outflow side of the filter member 4 and is in contact with the outer peripheral surface of the filter member 4 over its entire height.

In this embodiment, the flowing water in the water pipe 1 flows from left to right as shown by an arrow P in FIG. 1, for example. At that time, since the flowing water flows from the inside to the outside in the cylindrical filter mesh 35, impurities mixed in the flowing water are captured on the inner peripheral surface side of the filter mesh 35, and there. Deposits gradually. Further, impurities having a large specific gravity settle and are deposited on the upper surface of the partition plate 9.

When the accumulation of the impurities progresses to some extent, clogging of the filter mesh 35 eventually causes a considerable resistance to the water flow in the water pipe 1. In this case, impurities can be removed from the filter mesh 35 by backwashing the filter member 4 in a water-free state.

At the start of the backwash, the on-off valve 32 is first opened to allow the backwash chamber 14 to communicate with the communication tube 2 of the bottom plate 19.
5, the discharge chamber 17 and the discharge pipe 31 are opened to the outside (mainly atmospheric pressure). Thereby, the backwash room 14
Mouthwash 1 of filter mesh 35 surrounded by
In the vicinity of 5 and 15 ', a relatively high static pressure on the water pipe 1 side (i.e., the outside) and a relatively low external pressure on the backwash chamber 14 side (i.e., the inside) act. A backwashing action occurs on the basis of this.

At this time, as shown in FIGS. 1 and 4, the washed water flows into the discharge chamber 17 through the communication hole 7 of the backwashing chamber 14 and the communication tube 25. Then, through a spindle 13 extending outside the case 2, a backwashing port 15 of a backwashing chamber 14,
The inner surface of the filter mesh 35 is uniformly cleaned because the inner surface of the filter mesh 35 is rotated so as to move 15 ′ over the entire contaminant capturing area of the filter mesh 35.

At the same time, due to this rotation, impurities deposited on the partition plate 9 are removed as shown in FIG.
Are collected so as to be swept by the separators 16, 16 ′ that abut against. Further, as shown in FIG. 5, the contaminants collected by the separator 16 ′ are dropped into the discharge tube 28 through the discharge holes 8. At this time, the rotating plate 27 axially attached to the spindle 13 is also linked, but the communication between the discharge cylinder 28 and the discharge chamber 17 is still interrupted.

As shown in FIG. 6, the separator 16 ′ passes over the discharge hole 8 and the separator 16, which collects the impurities, reaches the discharge hole 8. And the communication hole 29 of the rotating plate 27 is
8, the discharge cylinder 28 and the discharge chamber 17 communicate with each other, and the contaminants collected by the separators 16 and 16 'are discharged to the discharge chamber 17 at once.

The contaminants deposited on the inner peripheral surface of the filter mesh 35 and the upper surface of the partition plate 9 are both completely removed and discharged from the discharge pipe 31 through the discharge chamber 17. Finally, the backwashing operation is completed by closing the on-off valve 32.

FIGS. 7 and 8 show an apparatus for removing impurities according to a second embodiment of the present invention. In this contaminant removal apparatus, as shown in FIG.
The bottom plate 19 constituting the backwashing chamber 14 is removed, and the upper surface of the partition plate 9 abuts against the bottom sides of the separators 16 and 16 ′ to constitute the backwashing chamber 14. In addition, a seal member 34 is mounted on a side of the separators 16 and 16 ′ in contact with the partition plate 9. Further, the rotary plate 27 is mounted on the spindle 13 such that the communication hole 29 is located directly below the backwash chamber 14.

In the contaminant removing apparatus using the filter member 4 configured as described above, the contaminant is removed by rotating the backwashing chamber 14 similarly to the contaminant removing apparatus of the first embodiment of the present invention. Removed. Further, as shown in FIG. 8, when the communication hole 29 of the rotary plate 27 matches the discharge tube 28, the discharge hole 8 of the partition plate 9 communicates with the backwashing chamber 14. Is also discharged to the discharge chamber 17 via the backwashing chamber 14, and there is an advantage that the entire inner peripheral surface of the filter can be washed with a uniform backwashing power without reducing the backwashing power.

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.

For example, in the embodiment, the filter mesh 3
Although 5 is a cylindrical shape, any shape may be used as long as it is not a perfect cylindrical shape but a separator that rotates by rotation of the spindle can slide.

[0029]

By opening the on-off valve connected to the discharge chamber, the water on the downstream side of the filter mesh starts flowing into the backwashing chamber, and the separator is rotated via the rotating shaft, thereby turning off the filter mesh. The entire inner peripheral surface is back-washed. At the same time, impurities also settle on the partition plate located on the lower surface inside the filter mesh, but through the discharge hole formed in the lower part inside the filter mesh, the through chamber and the discharge chamber communicate with a fixed cycle, The settled contaminants are also discharged to the outside via an on-off valve as appropriate, and maintenance work is greatly simplified.
