In general, water supply facilities are largely divided into water transmission facilities and drainage facilities. A water transmission facility is a facility that transmits water from a water purification plant to a drainage area installed on a mountain top. A drainage facility is a facility that stores in the drainage area and transports, distributes, and supplies the stored purified water, including drainage pipes, pumps, valves, and other ancillary facilities. do.

Water supply facilities are maintained to maintain proper water pressure so that water can be supplied stably in normal times and to maintain water supply in case of emergency.

The water supply area of a drainage facility is composed of a single or multiple drainage systems depending on the actual condition of water demand in the area, topography, and topography. It forms a pipe network composed of a drainage system, and is mainly maintained and constructed in the form of a block system so that maintenance is easy and the water quality in the pipe can be sufficiently maintained.

Therefore, the high-quality tap water produced at the water purification plant goes through the drain pipe through the drainage basin, and some of it is supplied by the booster pump of a small-scale unit of pressurization to provide smooth water supply to consumers located in the highlands where water supply is impossible through the drainage basin. After being pumped, it is supplied to consumers.

Due to the nature of these waterworks facilities, foreign substances generated in the process of transport and distribution after water purification and ) As in (b), a phenomenon such as a foreign substance 520 generated from the old pipe 510 comes off, and turbid water containing a foreign substance that may cause complaints is frequently detected by consumers.

It is estimated that the turbid water is generated by the sediment in the pipe end area as well as the old pipe 510 as in (a) (b) of FIG.

The phenomenon of foreign substances being detected due to old pipes will increase the farther away from the water purification plant, the longer the drain pipe, and the more steps you go through the process, such as a drainage basin and pressurization plant, in several stages.

Although the fundamental solution to the consumer complaints about drinking water is to replace the old water pipe as soon as possible, it is difficult in reality to replace the entire old water pipe, which is several hundred kilometers in length, at an early stage.

Currently, among old water pipes, distribution pipes with a diameter of 350 mm or less account for most of them compared to transmission and drainage pipes with a diameter of 400 mm or more. It will be possible to respond to areas prone to civil complaints only by strengthening the management of areas with poor water quality through the periodic discharge of stagnant water at the end of the pipeline.

However, it is not easy in reality to wash the water supply pipe (drain pipe) in the small block or to drain the stagnant water periodically at the end of the pipe, so improvement measures are required.

Hereinafter, specific details for carrying out the present invention will be described in more detail with reference to the accompanying drawings.

For residents who use tap water, the drinking water problem is a matter of water quality and safety directly related to the basic life of the residents. should be The problem of tap water quality required by consumers of water supply facilities is not solved just by making high-quality purified water at a water purification plant, but only when high-quality water is delivered to customers.

Accordingly, in the present invention, a pipe-type filter device is installed by selecting a pressurization plant at the end of a pipe or a major part of an area at the end of a pipe where impurities are frequently discharged as a place that is practically suitable and installable in relation to the customer, and the final filtration of foreign substances generated in the drain pipe or other drainage process By doing this, it is implemented so that high-quality tap water generated at the water purification plant can be properly supplied to residents (consumers) without turbid water despite the presence of foreign substances due to deterioration of pipelines. The causes of foreign substances in the water supply network are oxidation of metal pipes, peeling of paint, etc., sedimentation of organic and inorganic substances and slimes, biological effects, and improper maintenance of the water supply network. Foreign substances in tap water include not only inorganic components of corrosion products caused by internal corrosion and aging of pipes, but also a large amount of organic components containing carbon (C) components contained in the slime trapped inside the pipe.

In the present invention, while preventing abnormal symptoms of tap water, such as generation of turbid water in the consumer, in the waterworks facility management institution, without a fundamental solution such as immediate replacement of the old water supply pipe, proper maintenance for the current water supply facility can be performed well. It implements a water supply pipe type automatic filter system. The deterioration of the water supply and drainage pipes that form small blocks among water supply facilities and the sediments accumulated in the pipe end area (the end of the drainage pipe) act as disturbance factors that cause water quality fluctuations, causing turbid water to be generated in the tap water of consumers.

Accordingly, the present invention installs a water pipe having a through hole in each through hole of the filter cartridge tube body in which the inlet side of the full open form and the water outlet side of the multiple through hole open type are formed, and then, a filter member is provided on the outer surface of the water passage pipe to obtain, The turbid water introduced to the side is filtered primarily through the mesh filter and secondarily moved between the plurality of water pipes installed in the filter cartridge to have a filtration structure. It relates to a water supply pipe type automatic filter device with an improved replacement function having a combined filtration system for preventing turbid water that facilitates replacement of the entire filter cartridge unit in which the water passage and the filter member are installed. Foreign matter filtering function and replacement to prevent recurrence of turbid water in the consumer between the intake water supply line (10a) and the water outlet water supply line (10b) exposed to the inner chamber 100 of the inspection facility at the small pressurization plant or the end point of the water supply pipe of the facility A conduit-type filter device 70 having a function is installed in horizontal communication, and the filter cartridge 50 is filtered while the turbid water is moved in the conduit-type filter device 70 .

In the present invention, as a location to install the pipe-type filter device 70 for preventing the recurrence of turbid water in the consumer, it is selected as a small pressurization plant of a waterworks facility or a point at the end of the waterworks pipework. This is because distribution water pipes over 350 mm account for most of the old water pipes, and while it is related to consumers who need to prevent the recurrence of turbid water, practical management and realistic installation are suitable and possible.

As shown in FIGS. 2 and 3, the inspection equipment inner chamber 100 is mainly provided in the underground area of the road as shown in Figs. The square area of the inner chamber 100 is narrowly provided.

For this reason, in the embodiment of the present invention, even if the pipe-type filter device 70 has a narrow space environment, and even if the inflow and outflow directions of the inlet and outwater supply lines 10a and 10b are changed, the inspection facility inner chamber 100 As shown in FIGS. 2 and 3, the conduit-type filter device 70 includes a configuration feature that has a standing shape so that it can be installed without much problem and the user can check it.
