For example, various methods such as a physical filtration method using a filtering material, a chemical filtration or purification method using a chemical, or a filtration or purification method such as biochemicals using microorganisms are used. And, for example, for the large-scale and highly accurate purification of industrial water or drinking water, such various filtration methods may be used in combination.

技術が知られている。For filtration or purification of aquaculture ponds and other small-scale or low-precision filtration methods for household or commercial use, a filter medium (cotton-like material, felt-like material, porous sponge) is mainly used. Is common. As such a filtering method or device, for example, a technology is known in which a filter medium is housed in a filter tank, sand or activated carbon is used in combination in some cases, and water of a river or a pond is supplied to and passed through to purify it. Has been.

等においても発生する問題である。The above-mentioned filter material is capable of filtering algae and scales that grow in rivers and ponds, or suspended matter, and it is necessary that the filter material has a sufficient filter function. Needless to say. On the other hand, the fine filter material has a problem that it is clogged within a relatively short period of time. This is a problem that occurs not only in the cotton-like material but also in sand, activated carbon and the like.

のが普通である。In order to always maintain a good filtering function of the filter material, it is necessary to regularly wash and remove the above-mentioned clogging material (filtration residue). For that purpose, it is conceivable to take out the filter material from the filter tank, wash it, store it again in the filter tank, and reuse it. However, this kind of work is very time-consuming, and it is more economical to replace it with a new one, so it is common to take it out of the filter tank and replace it with a new one. Is.

ク内に納めた状態で濾過材(綿状体やフェルト状体、多
孔質スポンジ)を洗浄できないものかと考えた。In view of the uneconomicalness of the filtration method for exchanging the filter medium, the present inventor considers that the filter medium is preferably washed and reused. I thought that it would be possible to wash the filter material (cotton-like material, felt-like material, porous sponge) in the state of being stored in.

易に除去できないことが分かった。[0007] As one of them, in order to wash the cotton-like material and the felt-like material contained in the filtration tank, it was attempted to pressurize and wash the cleaning water. However, it has been found that the internal clogging of these filter materials having a three-dimensional shape such as a plate or a column cannot be easily removed.

考えた。[0008] Therefore, the present inventor has focused on a thin cloth-like body (so-called filter cloth) having a filtering function, passing water through it to filter, and thereafter, impurities which become a filtration residue contained in water. When the filter cloth was clogged with (algae, water stains, various suspended matters), it was thought that the filtration residue could be easily removed by spraying washing water on the thin filter cloth.

した。However, it has been found that such a thin filter cloth is too coarse to be able to exert a sufficient filtering function with only one piece. In addition, cleaning clogging of the filter cloth in the filtration tank means that even if the filter residue is smoothly separated, it will be mixed into the purified water, and a good filtration function will always be exhibited. There was a new problem that I could not.

ある。In view of the above-mentioned problems, the present invention is capable of exerting a sufficient filtering function while using a filter cloth that can be washed without being taken out from the inside of the filtration tank, and the filtration residue removed during washing is It is an object of the present invention to provide a filtration device which can be prevented from being mixed with purified water as much as possible.

め、充分な濾過機能を発揮させうるのである。According to the present invention, a filter cloth is wound around a filter winding shaft having a hollow hollow filter cylinder a plurality of times, and the filtration water is supplied into the filter cylinder, whereby a single filter is thin. Even though it is a cloth, it is possible to reveal a state in which a large number of sheets are overlapped, so that it is possible to exert a sufficient filtering function.

除去できるのである。When clogging progresses, the filter cloth is wound around the other winding shaft, and a cleaning liquid is sprayed on the filter cloth which has become one sheet in the winding process to remove the filter residue. So, compared to thick porous sponge and felt-like filter material, it is extremely easy and reliable to separate,
It can be removed.

れる恐れは殆ど無いのである。Then, the washing chamber is constructed in a substantially independent state in the filtration tank (slightly communicated with a slit that allows the movement of the filter cloth), and the outlet for discharging the washing liquid is used for this washing. Since it is provided in the chamber, there is almost no possibility that the filtration residue separated from the filter cloth by washing is mixed with the filtered water in the filtration tank.

の分、ポンプの圧力を上げずに済む。Further, when the cleaning nozzle mechanism comprises a nozzle capable of reciprocating in the width direction of the filter cloth, the whole area of the filter cloth moving by winding is covered. Therefore, the cleaning liquid can be reliably ejected. As a result, it does not require the diffusion state of the nozzle jets,
The nozzle can be jetted as close to the filter cloth as possible, and the pump pressure need not be increased accordingly.

防止できるのである。Further, when a pair of rotating rollers for holding the filter cloth in a position so as not to contact the slit are provided in the vicinity of the slit of the cleaning chamber, the rotating rollers can smoothly move the filter cloth. Of course, it is ensured, but the filter cloth greatly bends when pressurized water is sprayed onto the filter cloth by the cleaning nozzle mechanism (because the two winding shafts are separated).
Can be restrained to a slight deflection by these rotating rollers. As a result, it is possible to prevent the filter cloth from coming into contact with the slits and abrading to deteriorate or eliminate the filtering function.

る。Further, in the cleaning chamber, a punching metal plate which is located on the opposite side of the nozzle and receives the filter cloth is arranged parallel to the running direction of the filter cloth, and the cleaning liquid is placed behind the punching metal plate. When a discharge passage communicating with the discharge port of the filter cloth is provided, it is possible to prevent the filter cloth from largely deflecting due to the pressure when the cleaning liquid is sprayed by the above-described cleaning nozzle mechanism. The punching metal plate can be extracted and separated on the back surface side, and the separation and removal efficiency of the filtration residue can be improved.
