  Next, an embodiment of the present invention will be described according to the drawings. As shown in FIG. 1, the filtration device 1 according to the present invention is placed on the upper part of the aquarium fish tank 2, and the water pumped up by the submersible pump 3 is purified by passing through the filtration device 1, It is made to be returned to the water tank 1 from the outlet weir 4 at the end. As shown in FIGS. 2 and 3, the filtration device 1 sequentially receives the water receiving chamber 6, the first filtration chamber 7, and the pumping chamber from one end of the flat rectangular case 5 toward the other end. 8 and the second filtration chamber 9 and the outlet chamber 10 are formed.

  The water receiving chamber 6 is separated from the first filtration chamber 7 by the weir plate 11, and the diameter socket 12 whose inner diameter is expanded in a tapered shape has the outlet 13 facing upward and the bottom surface of the water receiving chamber 6. The hose 14 connected to the submersible pump 3 is disposed at the lower end of the fixed socket 12 projecting downward, and the water pumped up from the water tank 2 is discharged upward from the outlet 13. The internal diameter of the distraction socket 12 is expanded in a tapered manner toward the outlet 13, whereby the velocity of water flowing in the inside of the distraction socket 12 is lowered to the outlet 13, and the outlet 13 Attenuate the force of the water that blows out more. Also, a contact plate 15 is provided horizontally at the upper end edge of the gutter plate 11 so as to face the air outlet 13, and the water blown out from the air outlet 13 hits the lower surface of the relevant plate 15. In addition, the water that has hit the relevant plate 15 passes through the gap 16 between the relevant plate 15 and the inner surface of the case 5 and bypasses the upper portion of the relevant plate 15 as shown by the arrows, It overflows from the upper inflow opening 17 and is allowed to flow into the first filtration chamber 7. In addition, a wedge-shaped guide plate 18 inclined downward is provided at the upper edge portion of the upper inflow opening 17, and the water discharged from the upper inflow opening 17 is guided downward by the guide plate 18. The guide plate 18 is formed at one end of a horizontal closing plate 19 closing the upper portion of the water receiving chamber 6, and the upper inlet opening 17 is covered by the guide plate 18 and the closing plate 19. The tip end of the guide plate 18 extends slightly below the upper edge of the scissor plate 11 so that the water receiving chamber 6 is filled with the water blown out from the outlet 13 under normal conditions. Even if water is vigorously discharged from the outlet 13 to the water receiving chamber 6, air bubbles do not occur and noise does not occur. The entire upper surface of the case 5 is covered by a removable cover plate 20.

  The first filtration chamber 7 and the pumping chamber 8 are separated by a weir plate 21, and a lower end edge of the weir plate 21 is provided with a gap between it and the lower surface of the case 5 to form a first bottom opening 22. There is. The upper edge of the scissor plate 21 and the lid plate 20 are separated. Then, a filter medium 23 formed in a mat shape by glass wool, a cloth woven fabric or the like is disposed in the first filtration chamber 7.

  The pumping chamber 8 and the second filtration chamber 9 are separated by a weir plate 24 whose height is smaller than that of the weir plate 21 so that the overflow port 25 is formed. Further, the second filtration chamber 9 and the water discharge chamber 10 are separated by a weir plate 26 having the same height as the weir plate 24. In the second filtration chamber 9, a filter medium 27 formed in a mat shape by glass wool, cloth cloth or the like is disposed. In the lower half of the weir plate 26, a second bottom opening 28 formed of a plurality of slit-like openings is formed. Then, two straight cup-like sockets 30 are provided on the bottom of the water discharge chamber 10 so that the outlet 29 is opened, and the water is discharged from the water discharge chamber 10 by joining the outlet 4 to the lower end of the socket 30. Flows out to the water tank 2 through the outflow weir 4.

  In the filtration device configured in this manner, the water pumped up from the water tank 2 is decelerated by passing through the diameter socket 12, and the water discharged from the outlet 13 hits the contact plate 15 and bypasses the upper part of the relevant plate 15. As a result, the flow becomes gentle and flows out of the upper inflow opening 17 into the first filtration chamber 7. For this reason, even if water pressurized and pressurized by the submersible pump 3 flows into the water receiving chamber 6, the amount of circulating water can be increased without causing noise. The water that has flowed into the first filtration chamber 7 settles while being purified by the filter material 23, flows from the first bottom opening 22 into the pumping chamber 8, and rises in the pumping chamber 8. Then, the water overflowing from the overflow port 25 into the second filtration chamber 9 settles in the second filtration chamber 9 while being purified by the filter medium 27, and flows out to the water outlet chamber 10 through the second bottom opening 28 to flow out. It flows out from the weir 4 into the water tank 2.

  The water pumped up from the water tank 2 in this way is purified by flowing from the top to the bottom of the first filtration chamber 7 and the second filtration chamber 9 by its own weight, so that the resistance to the running water Less is. For this reason, in this filtration device, the amount of circulating water can be set large, and furthermore, the water is filtered in both filtration chambers 7 and 9, so by appropriately selecting filter media 23 and 27 in both filtration chambers 7 and 9. , It is hard to clog, high filtration performance is exhibited, and maintenance becomes easy.

  In this filtration device, even if excess water exceeding the filtration capacity flows into the first filtration chamber 7, the water overflows from the upper edge of the weir plate 21 to the pumping chamber 8. In addition, even if water exceeding the filtration capacity flows into the second filtration chamber 6, the water overflows from the upper edge of the gutter plate 26 to the water discharge chamber 10 and is returned to the water tank 2, so the water permeability of the filter media 23, 27 Even if it falls, there is no hindrance to the water circulation, and a sufficient amount of water can always be pumped and circulated from the water tank 2.
