Abstract
Description
Technical Field
[0001] The present invention relates to a suction body that is installed in an aquarium for breeding and cultivating fish and the like, and simultaneously collects suspended substances floating in water and on the water surface when sending the water in the aquarium to a foam separation device.
Background Art
[0002] In an aquarium for breeding and cultivating fish and the like, in addition to bubbles generated during aeration, foamy suspended substances float on the water surface. Generally, this foamy suspended substance can be discharged outside the path by overflowing it together with the drainage water by providing a drain outlet at the wall surface portion at the water surface height of the aquarium. However, in an aquarium made of fiber-reinforced plastic (FRP) with a structure in which a rubber sheet is laid, holes cannot be made in the wall surface portion in order to maintain watertightness. In such an aquarium, it is necessary to directly suck the suspended substances from inside the aquarium and discharge them outside the aquarium.
[0003] Therefore, Patent Document 1 discloses a foam removal device that can suck and remove a layer of bubbles floating on the water surface of an aeration tank or the like. This device has a suction pipe with a closed tip and slits on the side surface. The lower end of the slit is connected to the suction pipe of a blower in the vertical direction at a height where it is submerged in the water surface of the aeration tank. It is configured to enable stable suction even when there are waves on the water surface. When a continuous layer of bubbles is formed around the suction pipe, due to the adhesion force of the bubbles themselves, the layer of bubbles can be attracted and sucked from a wide range of the water surface. In addition, when the layer of bubbles contains putrefactive suspended substances, such as protein scum generated by aeration of water for cultivating aquatic animals, a foam separator can be provided in the middle of the suction pipe to remove the bubbles and prevent contamination of the blower.
[0004] However, suspended matter in aquariums used for raising and cultivating fish and other aquatic life is not only present on the surface but also in large quantities in the water. In particular, suspended matter in the water mainly consists of protein-based waste products such as feed residue and fish excrement. If left untreated, this will turn into ammonia, contaminating the water and creating an environment where pathogenic bacteria can easily proliferate. Therefore, it is necessary to collect not only the foamy suspended matter floating on the surface but also the suspended matter floating in the water. [Prior art documents] [Patent Documents]

[Figure 6] Schematic diagram showing a different mounting example of the suction unit to the water intake pipe than that shown in Figure 3. [Modes for carrying out the invention]
[0016] As shown in Figure 1, the suspension suction body 1 in this embodiment is attached to the tip of the suction pipe 3 connected to the foam separation device 2. The suction body 1 is positioned in the water tank 4 at an elevation angle to the water surface, with a portion of it submerged at the water surface. The suction body 1 can be installed in two or more locations on one foam separation device 2, or it can be installed in two or more locations on one suction pipe 3 connected to the foam separation device 2.
[0017] As shown in Figures 2 and 3, the suction body 1 consists of a mounting plate 5 attached to the tip of the suction pipe 3 connected to the foam separation device 2, and a connecting plate 6 that is superimposed on the mounting plate 5 while being held at an arbitrary distance. In all embodiments from Figures 1 to 6, the mounting plate 5 and the connecting plate 6 are rectangular, but any shape can be selected, such as elliptical or circular. The mounting plate 5 and the connecting plate 6 do not have to be the same shape; different shapes can be selected, and not only the shape but also the size of each can be freely selected. Furthermore, the mounting plate 5 and the connecting plate 6 can be made of curved material rather than flat, and each can be made of a different material. Furthermore, the thickness of the mounting plate 5 and the connecting plate 6 can be freely selected.
[0018] A spacer 7 is installed between the mounting plate 5 and the connecting plate 6 to maintain the gap. The thickness of the spacer 7, that is, the distance between the mounting plate 5 and the connecting plate 6, can be freely selected as long as it can achieve the purpose of aspirating suspended matter. In the embodiment shown in Figure 2, the spacer 7 is installed on the edges of two horizontally opposing sides, but it can be installed at any location, and multiple spacers can be installed. The suction body 1 can also be configured without a spacer 7, as long as the distance between the mounting plate 5 and the connecting plate 6 can be maintained.
[0019] When the spacer 7 is installed on the edges of the mounting plate 5 and the mating plate 6, it can be installed on one or more arbitrary edges, or it can be installed on all four edges. When the spacer 7 is installed on the edge of any side, one or more gaps can be provided in the middle of the edge, or gaps can be provided at the corners of the suction body 1 where the spacers 7 installed on the edges of all four sides intersect. If gaps are provided, the water in the tank 4 is drawn in through the gaps in the middle of the edges or through the gaps at the corners of the suction body 1 where the spacers 7 intersect.
[0020] As shown in Figures 4 and 5, the mounting plate 5 has an opening 9 in the portion that is attached to the tip of the water intake pipe 3. Therefore, the water in the tank 4 containing the suspended matter 8, which is sucked in through the gap between the mounting plate 5 and the connecting plate 6, is drawn into the suction pipe 3 through the opening 9 in the mounting plate 5 and sent to the foam separation device 2. When two or more laminated plates 6 are used, an opening 9 is formed in all of the laminated plates 6, except for the one that is furthest from the mounting plate 5, at a position that overlaps with the opening 9 of the mounting plate 5. As a result, the water in the tank 4 containing the suspended matter 8, which is sucked in from the gap between the mounting plate 5 and the joint plate 6, and from the gap between the joint plates 6, is drawn into the suction pipe 3 through the opening 9 in the mounting plate 5 and sent to the foam separation device 2.
[0021] The mounting plate 5 is installed such that its top edge and bottom edge, or only its top edge, are higher than the top edge and bottom edge, or only its top edge, of the overlapping plate 6 that it is superimposed on. In other words, the mounting plate 5 and the connecting plate 6 are not installed by overlapping them so that their contours perfectly match, but rather by overlapping them with a slight offset. As a result, even if the water surface in the tank 4 becomes wavy, the top surface of the mounting plate 5 can capture the suspended matter 8 floating on the water surface, thereby increasing the suction efficiency of the suspended matter 8. Furthermore, if the suction efficiency of the suspended matter 8 is not required, the top surface of the mounting plate 5 can be installed at a lower position than the top surface of the overlapping plate 6, or the mounting plate 5 and the overlapping plate 6 can be overlapped so that their contours perfectly match.
[0022] The suction body 1 is positioned at a height where a portion of it is submerged in the water. This allows for the simultaneous suction of suspended matter 8 in the water and on the water surface. Furthermore, the suction body 1 is positioned at an elevation angle relative to the water surface. As a result, suspended matter 8 floating in and on the water surface is less susceptible to resistance from the mounting plate and is more easily attracted. In addition, as shown in Figure 6, the suction body 1 can also be positioned at an inclined angle to the water surface, unlike in Figure 3.
[0023] Furthermore, two or more laminated boards 6 can be used. In this case, the spacers 7 are installed between the mounting plate 5 and the connecting plate 6, and between the connecting plate 6 and another connecting plate 6. In addition, the opening 9 is formed in the portion of the mounting plate 5 that is attached to the tip of the water intake pipe 3, and an opening 9 is also formed in all of the overlapping plates 6 except for the overlapping plate 6 that is furthest from the mounting plate 5, at a position that overlaps with the opening 9 of the mounting plate 5.
[0024] The suspended solids suction device, consisting of the above components, can be used in aquariums for raising and cultivating fish and other aquatic life, but it can also be used in any facility or environment where suspended solids are present in the water. [Explanation of Symbols]
