  By the way, in the said conventional water purifier, although it has a pump apparatus, generally as a pump apparatus, the spiral pump which accommodated the impeller which rotates in a case, or the vane pump which accommodated the vane which rotates in a case , A gear pump that houses a pair of gears in the case, a plunger pump that houses a piston in the case, etc. are used. Since the path is provided, there is a problem that the suction / discharge path becomes longer, the apparatus becomes larger, and the cost increases.

  The present invention has been made in view of the above problems, and eliminates the need for a case and shortens the suction / discharge path length as much as possible so that treated water can be sucked / discharged, thereby simplifying and reducing the size of the apparatus. An object is to provide a water purifier that can be manufactured inexpensively.

  In order to achieve such an object, the water purifier of the present invention is a water purifier for purifying by sucking, discharging, and treating treated water, and a rotating body that is rotated around a central axis along the vertical direction, and the rotating body. A rotating drive unit that rotates, and the rotating body has a suction port that opens into the treated water, and a discharge port that is provided radially outward of the central axis from the suction port and opens into the treated water. A suction / discharge channel that sucks treated water from the suction port and discharges it from the discharge port by centrifugal force generated on the discharge port side when the rotating body is rotated, and sucks the suction / discharge channel. It is set as the structure which provided the filtration member which filters a treated water so that attachment or detachment was possible on the opening side and / or the discharge port side.

  As a result, the suction port and the discharge port of the suction / discharge channel are opened in the treated water. When the rotating body is rotated by the rotation drive unit, the suction port is processed by the centrifugal force generated on the discharge port side of the suction / discharge channel. Water is sucked and discharged from the discharge port. Since the filter member is provided on the suction port side and / or the discharge port side of the suction / discharge flow path, the treated water is filtered and separated from dust and the like, and thus purified. The filter member is removed and cleaned in a timely manner. According to this device, the rotating body does not require a case, and it is not necessary to provide a separate suction path or discharge path as in the prior art, and the length of the suction / discharge path becomes the suction / discharge path length. The length of the suction / discharge path can be shortened as much as possible, and the treated water can be sucked / discharged. Accordingly, the apparatus can be simplified and miniaturized, and can be manufactured at low cost.

  In the present invention, it is effective to provide an air supply path for drawing air into the treated water in the suction / discharge flow path by the rotation of the rotating body. Since air is drawn into the treated water in the suction / discharge flow path, the suction action of the treated water can be reliably performed, and the purification action by aeration can be improved.

  In this case, a plurality of the suction / discharge passages can be provided, and each of the suction / discharge passages can be arranged at a rotationally symmetric position around the central axis of the rotating body. Since a plurality of suction / discharge passages are provided and each suction / discharge passage sucks and discharges the treated water individually, the suction action by the centrifugal force can be increased, and the suction ability can be improved. Further, since the treated water is sucked from the suction port at the rotationally symmetric position around the central axis of the rotating body and the treated water is discharged from the discharge port, the balance between suction and discharge can be improved.

  In this configuration, each suction / discharge channel is formed in an elbow shape with one opening as the suction port and the other opening as the discharge port, and each suction / discharge channel is directed downward with the suction port facing downward. It is arranged at a rotationally symmetrical position around the central axis of the rotator so that the discharge port faces sideways, and has a recess below the rotator that opens downward and faces the suction ports. It is effective to provide a cup-shaped cover. At the time of suction of each suction port, the treated water is collected in the cup-shaped cover and sucked into each suction port, so that impurities such as dust can be taken in reliably. In addition, each suction / discharge channel is formed in an elbow shape, and the suction port faces downward and the discharge port faces sideways. Therefore, centrifugal force is applied in the radial direction to reliably suck and discharge the treated water. be able to.

  And it is set as the structure which mounts the said rotary body and rotation drive part in the floating body floated in a treated water as needed. Thereby, since this water purification apparatus can be appropriately floated in required places, such as a lake, a dam, a water tank, etc., purification of the treated water over a wide range can be performed.

  Further, if necessary, the rotation drive unit is configured by a mechanism that rotates the rotating body by natural energy. For example, wind power and sunlight can be used.

  In this case, the rotating body is provided with a shaft portion centering on the central axis of the rotating body so as to protrude from the water surface of the treated water, and the floating body includes a bearing portion that pivotally supports the shaft portion, It is effective that the rotational drive unit is constituted by a windmill linked to the shaft portion. Since the rotating body is directly rotated by the windmill, for example, the energy extraction efficiency is good and the structure is extremely simple compared to the case where the generator is used to generate power and the rotating body is rotated by an electric motor. The size can be further reduced and the cost can be reduced.

  In addition, if necessary, the filtering member is formed of a bag-like net that can be attached to and detached from the discharge port. Since it is a bag-like net, it is easy to capture impurities such as dust, and the filtration member can be removed and cleaned in a timely manner, but since it is a net, impurities such as collected dust can be easily discarded and washed. Can be easily performed.

  According to the present invention, the rotating body does not require a case, and it is not necessary to provide a separate suction path or discharge path as in the prior art, and the length of the suction discharge path becomes the suction discharge path length. The length of the suction / discharge path can be shortened as much as possible, and the treated water can be sucked / discharged. Accordingly, the apparatus can be simplified and miniaturized, and can be manufactured at low cost. If the present invention is installed in a lake, a dam, a water tank, etc., the water quality can be easily purified, which is extremely useful.
