式の濾過装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filtration device, particularly a flat suction section that is installed at the bottom of an aquarium so as to be buried in gravel spread in the aquarium and has a water absorption hole in the upper wall, and a purification section connected to the suction section and housing a filter body therein for filtering water introduced into the aquarium through the suction section; The present invention relates to a filtration device having a water absorbing means, which performs a filtration action not only on the filter body but also on a gravel layer above the suction section.

にはない独特の利点を有している。 This type of filtration device is conventionally known as a so-called bottom type filtration device (see, for example, Japanese Utility Model Application Publication No. 51-80499), and in this type of device, filtration is performed primarily in a gravel layer spread at the bottom of the aquarium. It has a unique advantage that so-called top-type filtration devices do not have, such as the ability to effectively use organic matter such as leftover food and feces of ornamental fish as nutrients for aquatic plants planted in the gravel layer.

題がある。 By the way, in the above-mentioned bottom type filtration device, if the water absorption rate in the gravel layer or filter body is too slow and water stagnates, the reproduction of anaerobic microorganisms in the gravel layer or filter body will be promoted and the ornamental fish in the aquarium will be destroyed. On the other hand, if the water absorption rate is too fast, the growth of aerobic microorganisms in the gravel layer and filter will be inhibited, making it difficult for aerobic microorganisms to decompose organic matter. However, especially with conventional devices, all of the water sucked into the suction unit through the gravel layer always passes through the filtration surface of the filter before being sucked into the water absorption means, so there is a risk of clogging of the filtration surface. The water absorption rate changes greatly depending on the degree of water absorption, and especially when the filtration surface is completely clogged, the water absorption effect of the suction part and the primary filtration effect of the gravel layer will be extremely insufficient. There is a problem of rapid deterioration of water quality.

される。 Next, the operation of the above embodiment will be explained. The operation of the water absorption means 4, that is, the supply of pressurized air from the pressurized air source 73 to the air injection tube 75 via the air supply pipe 74, causes the air in the riser pipe 71 to A large number of bubbles are generated at the lower end, and as these bubbles rise within the riser pipe 71, an upward flow is generated in the water within the riser pipe 71. Therefore, a negative pressure is generated in the purification chamber 30, and due to the pressure difference between this negative pressure and the lower water pressure in the water tank 1, water is sucked into the filter device 3 after flowing through the gravel 2. That is, after the water flowing through the gravel 2 is primarily filtered by the filtration action of the gravel 2,
Water flows into each flow path 22 of the suction section 8 from the water suction holes 23 and 24, and is further collected from each flow path 22 into a relatively large-capacity collecting chamber 26, and is introduced into the unpurified chamber 31 from there. Note that water is drawn into the unpurified chamber 31 from the water tank 1 through the water holes 39 and 60 from the upper part thereof. A portion of the water in the collection chamber 26 flows into the purification chamber 30 through the small hole 55, and the remaining water passes through the filter materials 5 and 6 and is filtered into the purification chamber 30.
1. In this manner, the water in the aquarium 1 is first filtered through the gravel 2, and then a portion of the water is secondarily filtered through the filter media 5 and 6, and then returned to the aquarium 1.

もできる。 In this filtration device 3, the inside of the purification chamber 30 defined by the filter media 5, 6 and both support plates 40, 41 is maintained at approximately the same negative pressure, and the purification chamber 30 is maintained at approximately the same negative pressure.
0 is provided across both ends of each flow passage 22 in the arrangement direction, so the negative pressure within each flow passage 22 is approximately the same. In addition, since the distance between the water suction holes 23 is set to become smaller as the distance from the purification chamber 30 increases, the negative pressure on the upper surface of the suction section 8 is maintained almost uniformly over its front surface. Therefore, the speed of water flowing through the gravel 2 is approximately uniform and appropriate over the entire flow range. Therefore, within the gravel 2, chlorella and aerobic microorganisms are encouraged to grow, and these aerobic microorganisms decompose organic matter such as leftover food and feces of ornamental fish.
Clogging of the gravel 2 can be prevented, and chlorella etc. can also be provided as live bait for ornamental fish.

られる。 In addition, in the filtration chamber 25, a portion of the water in the unpurified chamber 31 flows into the purification chamber 30 through the small hole 55, so that the speed of water passing through the filter media 5 and 6 can be maintained at an appropriate rate. , can promote the reproduction of the aerobic microorganisms. In addition, since the filter media 5 and 6 are bent in a wave shape and extend vertically, the filtration area can be made relatively large within a limited space and the filtration efficiency can be improved. This prevents air bubbles from accumulating on the outer surface of the container and obstructing the flow.

The water absorption action in the water absorption part 8 is carried out without any trouble,
An appropriate amount of water can always flow through the gravel layer 2, so that the primary filtration action by the gravel layer 2 can be continued and performed accurately.

Simply remove and lift the purifying section 9.
The inner filter bodies F 1 and F 2 can be lifted above the water surface together with the lids 10 and 11. Therefore, the filter material 5,
If the filter media 6 are removed from the frames 27, 28 and washed, or replaced with new ones, the clogging state can be cleared. After that, the filter media 5, 6 are reattached to the lids 10, 6 via the frames 27, 28. 11, and the lid 1
By charging it into the purifying section 9 together with 0 and 11, the filtration action can be performed again. Therefore, the filtration device 3 can be left in its normal operating state with the suction section 8 buried under the gravel layer 2, and the filter media 5 and 6 in the purification section 9 can be replaced very easily. When replacing the gravel layer 2, there is no risk that the arrangement of the gravel layer 2 or the aquatic plants planted therein will be disturbed or that the roots of the aquatic plants will be damaged.

なく、コストダウンに寄与することができる。 As described above, according to the present invention, the flat suction part is installed at the bottom of the aquarium so as to be buried in the gravel spread in the aquarium and introduces water in the aquarium through the gravel; A filter body is provided along one side edge of the suction part along substantially the entire length thereof, stands up above the suction part, and houses a filter body therein for filtering water introduced into the aquarium through the suction part. In the filtration device, the filtration device is equipped with a purification section and a water absorption means for circulating the water filtered in the purification section back into the aquarium, in which a gravel layer above the suction section performs a filtration action. The upper wall of the suction section is composed of a high section extending along and adjacent to the purification section, and a low section connected to the high section via a stepped section, and has a plurality of flow channels directly below the low section. and one collective chamber that communicates with one end of the plurality of flow passages directly below the high part, and the lower part has a plurality of chambers that communicate with each other between the flow passages and the inside of the water tank. an unpurified chamber in which a water absorption hole is bored, the filter body is opened in the purification section, and the gathering chamber is opened over substantially the entire length thereof;
a purification chamber communicating with the water absorption means, and a filter material for filtering a part of the water heading from the unpurified chamber toward the purification chamber, and a filter material for filtering the remaining water from the purification chamber. When the water absorption means is activated, the water sucked into each flow path of the suction section through the gravel layer is passed through a relatively large-capacity collecting chamber. Once collected,
From there, part of the water passes through the filter material, and the remaining water bypasses the filter material and can be accurately divided into the purification chambers through the small holes. Therefore, the opening area of the small holes can be adjusted appropriately. By setting these settings, it is possible to control the water passage speed through the filter media and gravel layer to an optimal value, suppressing the growth of harmful anaerobic microorganisms and promoting the growth of useful aerobic microorganisms in the filter media and gravel layer. This can contribute to water quality purification. Furthermore, even if the filter material becomes clogged due to use, the flow of water from the collection chamber to the purification chamber through the small holes is not obstructed, so an appropriate amount of water can always flow through the gravel layer. This is advantageous because the primary filtration action by the gravel layer can be performed continuously and accurately. In addition, the above meeting room is
Since it can be easily formed by simply making the part of the upper wall of the flat suction part along and adjacent to the purification part higher than other parts, the structure of the filtration device can be made special even by the special installation of the gathering chamber. It is not complicated and can contribute to cost reduction.
