ある。(Prior art and its problems) In general, in self-priming pumps, etc., in order to prevent straw, etc. from entering the volute case with water and clogging the water flow path of the impeller, A strainer is installed. Conventionally, this type of strainer, as disclosed in Utility Model Application Publication No. 53-103981, has a cylindrical body with a large number of water absorption holes in its circumferential wall, and filters out dirt by absorbing water from these water absorption holes. However, if the opening area of this water suction hole is too large, the filtration function will deteriorate, and if it is too small, the water suction resistance of the pump will increase. It is necessary to appropriately design the opening area.

る。(Function) As the pump 1 is driven, water filtered through the through hole 9 of the bottom plate 5b of the case 5 flows into the filter cylinder 6, and the water absorption window 81 and the dust removal opening window 8 of the case main body 5a flow. 2 is filtered through the water absorption holes 10 of the filtration cylinder 6, and then flows into the filtration cylinder 6. In this way, the filtration action is performed. To remove debris that has clogged the through holes 9 and water suction holes 10, the strainer 4 is lifted out of the water after the pump 1 stops operating. The water absorption window 8 1 of the case main body 5a is connected through the gap between
For dirt clogged in the water absorption holes 10 of the filtration cylinder 6 in the portion covered by the circumferential walls between them, use your fingers to directly touch the outer surface of the filtration cylinder 6 through the dust removal opening window 8 2 . By rotating it in the case 5 in such a manner as to expose the water absorption hole 10 in the part clogged with dirt from the part of the opening window 8 2 for removing dirt.
Clogged debris can be easily removed.

Is possible. In addition, since the filtering cylinder 6 is made of a heavy and thick metal plate, the filtering cylinder 6 also serves as a weight to keep the strainer fixed at the bottom of the water, so the strainer 4 can be submerged in the water. There is no need to provide a special weight for this purpose, which simplifies the configuration.

This prevents the cylindrical body from accidentally slipping out of the case, allows the hand to rotate the filtration cylindrical body, and allows the water absorption hole located between one end and the other end of the filtration cylindrical body in the axial direction to be The size may be such that almost the entire area is exposed. Furthermore, the materials and structure of the case and the filter cylinder may be changed in various ways without departing from the gist of the present invention.

たものである。(Effects of the invention) As detailed above, the pump strainer of the present invention is a cylindrical strainer that is attached to the tip of the water suction hose of the pump and has a large number of water suction windows between one end and the other end in the axial direction of the circumferential wall. It comprises a cage-like case, and a filtration cylindrical body that is rotatably housed within the case and has a large number of water absorption holes smaller than the water absorption window throughout the axially opposite ends of the circumferential side wall. At least one dust removal opening window is provided on the circumferential wall, exposing substantially all of the water absorption holes located between one end and the other end in the axial direction of the filtration cylinder.

確実に除去し得るという効果を奏する。 By employing such a configuration, the cylindrical case ensures strength against external forces received from the outer circumferential direction as a strainer, and the strength of the filter inside this case does not need to be considered much. Therefore, by simply replacing the filtration cylinder inside the cylindrical cage-like case, the case can be used as a common case to accommodate various pump specifications, and in this way, the inner filtration cylinder (filter filter) can be replaced with the outer cylindrical case. Because it is supported by a cage-like case, it is easy for dirt to get clogged, especially if it enters the water absorption hole of the filtration cylinder through the gap between the inner wall of the case and the outer wall of the filtration cylinder. Easily remove clogged debris from the opening window for removing debris.
It has the effect of being able to be removed reliably.
