めるものである。 Among sewage treatment facilities, sedimentation ponds have traditionally been installed as the simplest means of purifying water supply and wastewater in urban areas, factories, etc., and are usually made of concrete and have a circular or rectangular shape with a large surface area, and are usually installed outdoors. , sewage is continuously flowed in, sludge and other substances with a higher specific gravity than water are precipitated, the precipitates are constantly scraped up and discharged by a clarifier, and the supernatant water is allowed to overflow from the overflow wall at the periphery of the sedimentation tank, and This is to allow water to flow from the installed side gutter to the drainage ditch.

も必要としない清掃装置が要望されていた。 In recent years, new and expanded sewage treatment facilities have been built in various places as anti-pollution measures have increased, but sludge has become attached to the surrounding walls, overflow walls, gutter walls, etc. of these outdoor sedimentation tanks. In particular, sludge tends to adhere to overflow walls and side gutter walls that easily come into contact with the air, and depending on the type of sludge, microorganisms such as bacteria and bacteria can grow and become a source of odor, so it is necessary to prevent this odor. As a countermeasure, it is necessary to constantly clean the walls of the gutters, etc. In the case of many large-area sedimentation ponds, the length of the gutters etc. is also long, and a large number of cleaning employees are required. There was a demand for a cleaning device that does not require any special facilities.

ついて以下図面に示される円形沈澱池の実施例に
ついて説明する。 The present invention provides a simple cleaning device that can be installed by partially modifying a conventional clarifier, and is vertically supported so as to be able to rise and fall on the clarifier that runs on the side gutter of a sedimentation basin, and is installed vertically in the main body of the clarifier that runs on the side gutter of the sedimentation basin. A main shaft that can run in the center, two sets of inner and outer arm frames that are supported on the main shaft in a hinge-like manner so that they can be opened and closed and that can come into sliding contact with both side wall surfaces of the gutter, and the outside of the one set of inner and outer arm frames. A cleaning member is installed at each end so as to be able to come into sliding contact with the wall surface of the gutter, and each of the arm frames is biased in the opening direction so that the cleaning member can always travel while being in sliding contact with the wall surface. This is a clarifier for a sedimentation tank in which a groove cleaning section is suspended from a clarifier main body, and its configuration will be described below with reference to an embodiment of a circular sedimentation tank shown in the drawings.

第１図に示す如く、沈澱池２６の周囲には円形
の内壁２が設けられ、内壁上面２７は沈澱池２６
の水面より突設され、円形水平面とされている。
また前記沈澱池２６の円形中央には中央基台２８
が水面上に突設されている。 As shown in FIG. 1, a circular inner wall 2 is provided around the sedimentation tank 26, and an upper surface 27 of the inner wall is formed around the sedimentation tank 26.
It protrudes from the water surface and has a circular horizontal surface.
In addition, a central base 28 is located in the circular center of the sedimentation tank 26.
is protruding above the water surface.

Gently scrape it up and discharge it to the outside of the sedimentation tank 26.

に保持されている。 The supernatant water from which the sediment has been removed flows through an opening (not shown) in the inner wall 2 to an overflow groove 5 provided in an annular shape outside the inner wall 2, and flows into the horizontal overflow wall of the overflow groove 5. 6, the water flows out into a side gutter 7 provided in an annular shape around the overflow gutter 5, is collected in a drainage gutter 8, and is discharged to the outside. Therefore, the water surface of the sedimentation tank 26 is regulated by the horizontal upper surface of the overflow wall 6 and is always maintained at the same height.

段が強く望まれていた。 Inner wall surface 29 and outer wall surface 3 of the side gutter 7
0. Unsedimented substances floating in the overflowing water are also deposited on the side walls 31, 31 of the overflowing groove 5 and the upper surface of the overflowing wall 32, which are always in contact with overflowing water, but especially when organic matter is dissolved in the overflowing water. Microorganisms propagate due to biochemical reactions during overflowing water, and are likely to adhere to the inner and outer wall surfaces 29 and 30 of the gutter 7, which are close to the stagnant water surface and often come into contact with air. In the summer, the aqueous sludge that has grown with the microorganisms mentioned above can become very thick and emit a foul odor, and we often receive complaints from residents of neighboring houses near the sedimentation ponds installed outdoors. Various measures and ideas have been devised, such as covering the entire sedimentation basin, constructing the sedimentation basin in a large indoor area, and increasing the frequency of cleaning of the sedimentation basin, but none of these measures However, there is a strong desire for simple countermeasures and means that are not economical and require less expense, as the costs such as maintenance and maintenance costs are high and a large amount of manpower is required.

清掃装置４の保全も容易である。 The present invention is a cleaning facility with a simple structure that meets the above-mentioned requirements, and can be used even in existing outdoor sedimentation basins by modifying a part of the clarifier, as shown in Figure 1. As shown, the cleaning device 4 is installed in the side groove 7 near the outer end of the clarifier main body 1.
As the clarifier body 1 travels, the cleaning device 4 slides into wall surfaces to which sludge deposits have adhered, such as the inner wall surface 29 and outer wall surface 30 of the gutter 7, and mechanically removes the sludge deposits. The cleaning device 4 is peeled off from the concrete wall surface by friction and discharged together with the discharged water, and the cleaning operation does not require any special driving power and is carried out continuously and automatically, making it easy to maintain the cleaning device 4.
