It is a system figure showing the composition of the purification device concerning the embodiment of the present invention. It is a side view of the purification apparatus which concerns on embodiment of this invention. It is a rear view of the purification apparatus which concerns on embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  The purification device 100 shown in FIGS. 1 to 3 is installed by being transported to a place where there is no water supply facility, for example, at the time of a disaster, etc., purifies the water sucked up from a river or pond, and supplies drinking water or domestic water.

  The purification device 100 includes an automatic pump 20 that is rotationally driven by an electric motor 25, a manual pump 30 that is driven when a person operates a handle 31, and a filtration that filters water sent from the automatic pump 20 or the manual pump 30. And a container 50.

  As shown in FIG. 1, the purification device 100 includes a pump circuit 40 that discharges water sucked by the automatic pump 20 or the manual pump 30, and a filtration circuit 58 that filters water by the filter 50.

  The pump circuit 40 bypasses the suction passage 41 that guides the water sucked into the automatic pump 20, the first check valve 42 that is interposed in the suction passage 41 and stops the reverse flow of water, and the first check valve 42. And a bypass passage 43 that guides water to be sucked into the manual pump 30.

  A strainer 45 is connected to the tip of the suction passage 41. Water is taken into the suction passage 41 from the strainer 45 introduced into the river or pond.

  The first check valve 42 opens with respect to the flow of water sucked into the manual pump 30 through the suction passage 41, while closing with respect to the flow of water about to flow backward through the suction passage 41.

  The non-volumetric automatic pump 20 includes a rotor that is rotatably accommodated with a gap on the inner wall surface of a pump housing (not shown), and the blades of the rotating rotor discharge water sucked by applying centrifugal force to the water. It consists of a centrifugal pump that does. However, the present invention is not limited to this, and the automatic pump 20 may be constituted by an axial flow pump that discharges the water sucked by the rotating rotor blades applying axial force to the water.

  In the automatic pump 20, when there is no water in the pump housing at the start of operation, the rotor runs idle and water cannot be sucked through the suction passage 41. For this reason, in the automatic pump 20, it is necessary to put priming water into the pump housing at the start of operation when there is no water in the pump housing.

  As a countermeasure, a positive displacement manual pump 30 is interposed in the bypass passage 43. The positive displacement manual pump 30 includes a cylinder provided in a pump housing (not shown) and a piston slidably fitted in the cylinder. In the manual pump 30, when the handle 31 is repeatedly rotated by a person, a piston (not shown) reciprocates in the cylinder to expand and contract the pump chamber. The manual pump 30 sucks water from the suction passage 41 through the bypass passage 43 by the negative pressure generated in the cylinder even when there is no water in the pump housing at the start of operation, and the pump of the automatic pump 20 from the bypass passage 43 through the suction passage 41. Water can be supplied into the housing.

  The manual pump 30 is not limited to the configuration described above, and a positive displacement pump that sends water by changing the volume of a pump chamber that is expanded and contracted by a diaphragm may be used. Further, the manual pump 30 may be a positive displacement pump that sends water by another configuration.

  The bypass passage 43 is connected between the first check valve 42 of the suction passage 41 and the manual pump 30. In other words, the outlet (downstream end) of the bypass passage 43 is provided downstream of the first check valve 42 of the suction passage 41 and upstream of the suction port of the manual pump 30 of the suction passage 41. When the manual pump 30 is operated, water supplied from the bypass passage 43 to the suction passage 41 is closed by the first check valve 42 being closed by the discharge pressure of the manual pump 30 guided from the bypass passage 43 to the suction passage 41. Does not flow back and is guided into the automatic pump 20.

  A second check valve 44 is interposed in the bypass passage 43 on the upstream side of the manual pump 30. The second check valve 44 opens with respect to the flow of water sucked into the manual pump 30 through the bypass passage 43. On the other hand, the second check valve 44 is closed with respect to the flow of water that attempts to flow backward through the bypass passage 43.

  During operation of the manual pump 30, river or pond water is sucked up by the manual pump 30 through the suction passage 41 and the bypass passage 43. Water discharged from the manual pump 30 is sent to the suction port of the automatic pump 20 through the bypass passage 43 and the suction passage 41. The water flowing into the suction port of the automatic pump 20 flows out from the discharge port of the automatic pump 20 through the gap between the pump housing of the automatic pump 20 and the rotor and is sent to the filtration circuit 58.

  On the other hand, when the automatic pump 20 is operated, the water of the river or pond is sucked up by the automatic pump 20 through the suction passage 41. The water discharged from the automatic pump 20 is sent to the filtration circuit 58.

  A pressure gauge 36 is interposed in the pump circuit 40. The pressure of water led to the filter 50 from the automatic pump 20 or the manual pump 30 is measured by the pressure gauge 36.

  First to fifth filtration cartridges 51 to 55 constituting the filter 50 are interposed in the filtration circuit 58.

  The first filtration cartridge 51 is interposed on the most upstream side of the filtration circuit 58. The first filter cartridge 51 accommodates a prefilter element (not shown).

  The second filtration cartridge 52 and the third filtration cartridge 53 are interposed in parallel with the filtration circuit 58. The second filter cartridge 52 and the third filter cartridge 53 contain a bobbin filter element. The spool filter element has a higher filtering performance than the upstream prefilter element.

  The fourth filtration cartridge 54 and the fifth filtration cartridge 55 are interposed in series with the filtration circuit 58. The fourth filtration cartridge 54 and the fifth filtration cartridge 55 contain activated carbon elements.

  The water flowing through the filter circuit 58 is filtered and purified by passing through the first to fifth filter cartridges 51 to 55 constituting the filter 50, thereby being used as drinking water or domestic water.

  The generator 60 includes an engine that rotationally drives a power generation mechanism (not shown). The engine is operated by burning fuel such as gasoline. The electricity generated by the generator 60 is sent to the electric motor 25 of the automatic pump 20 through the electric wire 61. Alternatively, the electricity generated by the generator 60 may be sent to the light 63 through the electric wire 62 and illuminated by the light 63. However, the present invention is not limited to this, and the generator 60 may be used as a power source for operating other electrical devices.

  When the purification apparatus 100 is used, the generator 60 is operated, and the automatic pump 20 is activated by electricity sent from the generator 60. The electric motor 25 is not limited to electricity sent from the generator 60 but may be operated by electricity sent from another power supply facility.

  As will be described later, when the automatic pump 20 cannot be operated in a situation where the generator 60 cannot be used or in a situation where other power supply facilities or the like cannot be used, the manual pump 30 is manually operated.

  When the manual pump 30 is operated, water flowing from the manual pump 30 to the suction port of the automatic pump 20 flows out from the discharge port of the automatic pump 20 through the gap between the pump housing and the rotor of the automatic pump 20 and is sent to the filtration circuit 58. . In this way, the purification apparatus 100 can purify water in a place where there is no power source or the like.

  As described above, even when the manual pump 30 is operated while the automatic pump 20 is stopped, the water sent from the manual pump 30 is guided to the filtration circuit 58 through the automatic pump 20. It is possible to prevent water from staying in the water and prevent the inside of the automatic pump 20 from being contaminated.

  Further, in the state where the automatic pump 20 is activated and the manual pump 30 is stopped, when water stays in the manual pump 30, a person operates the handle 31 several times to activate the manual pump 30. It is possible to prevent water from being pumped into the manual pump 30 and contaminating the manual pump 30.
