る。(Prior Art) The filtration element of the strainer has a filtration gap, and serves to prevent foreign matter in the liquid of a predetermined size or larger from passing through, and to supply the filtered liquid to the secondary side. is in charge of Foreign matter of various sizes adheres to the surface of the filter element, and sometimes the foreign matter bites into the gaps, thereby blocking the flow of liquid. For this reason, a foreign matter scraping device is provided to remove foreign matter from the filter element. However, even the foreign matter scraping device cannot completely remove foreign matter, so when the filtration resistance of the filtration element exceeds a predetermined value, the filtration operation is temporarily stopped, and the filtration element is taken out and cleaned. In particular, the foreign matter is removed.

ばならない回数が多くなるという問題もあつた。(Problems to be Solved by the Invention) However, the biggest problem with conventional strainers is that foreign matter stuck in the voids of the filter element accumulates and causes a bridging phenomenon. Once the void is blocked by this phenomenon,
Problems arise in that it is difficult to remove foreign matter with a scraping device, and it is also difficult to remove it by cleaning. In addition, in the conventional example, since the bridging phenomenon is likely to occur,
Another problem was that the filtration work of the strainer had to be stopped and cleaned many times.

する問題があつた。 Further, the cylindrical filtration element is composed of a punching plate or a wedge wire, but when forming the cylindrical shape with the punching plate, it is difficult to achieve sufficient roundness, and uneven portions are likely to occur. In the case of a wedge wire, since the wedge wire is simply wound in a polygonal shape to form an approximately cylindrical shape, a large sliding resistance occurs between the wedge wire and the foreign matter scraping device that slides in sliding contact with the wedge wire while rotating relatively. There is a problem in that it is difficult to rotate smoothly, and it is necessary to increase the power of the drive motor and increase the running cost for relative rotation.

に減らすことができる。 Fluorine-based resins have a very low coefficient of friction, making it difficult for foreign substances such as dust to adhere to them. Therefore, since the periphery of the filtration gap of the cylindrical filter element is coated with the fluororesin, it is possible to drastically reduce the bridging phenomenon caused by foreign matter in the gap. Furthermore, even if foreign matter adheres to or gets stuck in the void, the coefficient of friction between the foreign matter and the surface of the void coated with fluororesin is extremely small, so it will slide into contact with the outer circumference of the cylindrical filter element, and the relative This can be easily removed automatically by a rotating foreign material scraping device.
The filtration performance of the cylindrical filtration element can be easily maintained in good condition, and the number of times the filtration element must be cleaned can be significantly reduced.

る。 The outer periphery of the cylindrical filtration element is covered with fluororesin, which has a very small coefficient of friction, and the foreign matter scraping member rotates relative to the fluorine-based resin that slides on it.As a result, the sliding resistance can be significantly reduced. Problems related to the roundness of the filter element can be alleviated, the power of the drive motor used for the relative rotation can be reduced, and running costs can be reduced. Note that since the fluid resistance of the cylindrical filter element is reduced, running costs can also be reduced from this point of view.
