Description

Overflow sump tank {Overflow type sump tank}

The present invention relates to a fish tank or a tank for ornamental or sale exhibition.

Fish tanks are used to raise ornamental freshwater or saltwater fish. In the live fish market, tanks are used to store live fish for sale. Fish tanks and tanks will be equipped with water and oxygen to keep the fish alive. Furthermore, it can be equipped with a temperature control device for maintaining a proper temperature, a filtration device for maintaining a proper water quality, a carbon dioxide supply device for a few seconds and an illumination device for securing the amount of light.

Filter devices have been developed in various ways, mainly in ornamental tanks. The filtering device removes contaminants caused by extra food or fish excretion that fish did not ingest by physical, chemical or physiological methods. It is divided into floor filtration device, side filtration device and external filtration device according to the installation method. do.

In terms of efficiency, an external filter is recommended as a preferred one. Among them, there is a sump that can secure a large amount of water larger than the volume limit of the fish tank, so that the water quality fluctuates small and can easily install various filtrates.

One well-known sump type is the drilling of a hole in the bottom of a fishbowl and the installation of a tube in the hole to an appropriate level. The tube is connected to a separate treatment tank located at the bottom of the tank, so that the water flowing into the tube naturally flows down to the treatment tank. In the treatment tank, water introduced from the tube passes through at least one carrier, and the treated water is returned to the original tank by the submersible pump. Such sump fishing port has to make a hole in the bottom of the existing fish tank, there is a hassle of manufacturing, and the possibility of a possible leakage between the hole and the tube.

Another sump type is to install the tank and the treatment tank at about the same height, and use the inverted U-tube to transfer the water from the tank to the treatment tank. In order to move water through the inverted U tube, there is a technical disadvantage that a suction pump is connected to the outlet side of the inverted U tube (processing tank side) or a siphon principle is used in which the water tank and the treating tank have different levels. Furthermore, since the center of the inverted U-tube is always above the level of both tanks, air bubbles are easily generated in this area. These bubbles move toward the outlet of the inverted U-tube as the water flows, then move back into the pattern of buoyancy, which is a significant source of noise.

1 to 2 show a schematic view of an overflow sump fish tank according to an embodiment of the invention.

According to the embodiment of the present invention, the overflow sump fish tank 10 includes an extension portion 10, a treatment tank 2 and a recovery portion 3.

The water tank B has a box shape with an open top. The cross-sectional shape of the water tank (B) may be variously changed, such as a circle, an oval, in addition to the rectangle shown. Such a bath is made of synthetic resin such as reinforced acrylic or made of glass.

The extension 10 extends upwards while closing around the open upper end of the bath B. FIG. In the illustrated embodiment, the extension 10 is a vertically open structure that extends over each side of the tank B, and is rectangular in conformity with the four sides of the tank.

The extension part 10 is formed with a step 11 extending over the top of the tank, and the step 11 may be changed to another configuration over the end of the tank. Extension portion 10 and the water tank (B) is connected without leaking water. To this end, a silicone adhesive may be used as the known surface of the contact portion between the extension portion 10 and the water tank B.

As the extension part 10 is connected to the water tank B, the height of the water tank B is increased. That is, the maximum water level of the water tank B is raised by the extension part 10. Since the water surface is located in the extension, the water cannot be seen from the transparent window of the tank.

Compared to the conventional fish tank in which the water surface is formed in the upper part of the tank, the present invention not only improves the ornamental beauty by not monitoring the water surface, but also prevents the formation of material stations due to water evaporation, which has been a problem in the conventional fish tank. Convenience is increased.

One side of the extension portion 10 is formed with a discharge portion 12 for discharging water. The discharge part 12 is a hole formed in one side of the extension part 10 or a guide part described later.

The water discharged from the extension portion 10 is excess water overflowing from the water tank as the water is supplied to the water tank by the recovery unit described later. That is, since the water level in the water tank is higher than the height of the formation of the discharge portion 12, the surface water can be discharged to the outside through the discharge portion 12 by gravity (see Fig. 3).

In a further configuration, the guide portion 13 is a means for forming a flow path of overflowed water to guide the treatment tank. In the illustrated embodiment, the guide part 13 is a tube installed inclined downward in a direction away from the extension part 10. Guide portion 13 may be used in addition to the cylindrical tube U-shaped drip tray.

The water overflowed by the guide part 13 does not flow along the outer wall of the extension part 10 or the outer wall of the water tank B, but falls in the position separated by the length of the guide part 13.

The treatment tank 2 is a separate tank or tank through which water falling at the discharge portion passes. The treatment tank 2 is located on one side of the water tank B, which is shown as being located behind the water tank B in the figure. Alternatively, the treatment tank may be shaped to surround either side and the rear of the tank. The treatment tank 2 lies on substantially the same plane as the water tank B.

The treatment tank 2 is equipped with various filtering means. Here, the filtration means is known, and there are various carriers, sponges, sieves, ovaries, and the like.

4 shows the formation of a flow path by the plurality of partitions 21 as an example of the processing tank 2. The partition wall 21 is sequentially arranged in contact with the bottom of the treatment tank (2) and the bottom of the treatment tank 2, the partition wall in contact with the bottom of the treatment tank is lowered toward the left side.

Therefore, as shown, the introduced water becomes a downflow and an upward flow sequentially while passing through the partition wall, and is purified by the appropriately placed filtration means 22.

3 shows a connection relationship between the extension part 10 and the treatment tank 2. The guide part 13 extended from the extension part 10 is inserted through the inlet 23 of the processing tank 2 to the inside of the processing tank 2. Therefore, the water overflowed from the extension 10 flows into the treatment tank 2 evenly.

Although not shown, if the aforementioned guide part is not provided, that is, only a hole is formed in the extension part, a separate piping material connecting the hole of the extension part and the inlet of the treatment part may be further provided.

The recovery unit 3 is a means for pumping water collected in the treatment tank 2 and returning it to the water tank again. The recovery unit 3 may have various configurations as equipment for moving water from the low level of the reservoir B to the high level of the extension unit 10.

In the illustrated embodiment, the recovery part 3 is an underwater pump 31 installed at the bottom of the treatment tank 2, one end of which is connected to the outlet of the underwater pump 31, and the other end of the extension part 10. It includes a flow pipe 32 is connected to the upper end of the.

It is connected to the end of the flow pipe 32 in an additional configuration and includes a flow rate reduction portion 4 for reducing the kinetic energy of the water flowing inside to discharge the pumped water at low speed.

5 to 6 illustrate the flow rate reducing unit.

The flow rate reduction part 4 includes a diffusion case 41 connected to the flow pipe, and a diffusion part 42 mounted inside the diffusion case 41 to reduce kinetic energy of water.

The diffusion case 41 includes an expansion part 411 connected to the end of the flow pipe 32 and gradually spreading a cross-sectional area in the form of a fallopian tube, and a closing part 413 which blocks an end portion of the expansion part spaced apart. The expansion part 411 and the finishing part 413 are connected by the plurality of support blocks 415.

As the finishing part 413 and the expansion part 411 are spaced apart, an outlet 41a of the diffusion case 41 is formed. At this time, the outlet area of the diffusion case 41 is larger than the cross-sectional area of the flow pipe 32, and the outlet opening direction has a large angle with the water discharge direction at the end of the flow pipe. In FIG. 6, the outlet direction of the diffusion case 41 is substantially perpendicular to the water discharge direction at the end of the flow tube.

The diffusion part 42 is rotatably installed between the expansion part 411 and the finish part 413.

The expansion portion 411 is provided with an extended rib and the upper shaft connecting portion 412, the lower end of the connecting portion 413 is provided with a lower shaft connecting portion 414. The upper shaft connecting portion 412 and the lower shaft connecting portion 414 rotatably restrains the upper and lower ends of the rotary shaft 421 of the diffusion portion 42.

The resistance blades 422 are radially coupled to the rotation shaft 421. The resistance blade 422 is obliquely coupled to the rotation shaft 421, and forms a curved propeller blade.

In FIG. 6, the water introduced into the expansion part 411 is brought into contact with the resistance wings 422 while moving downward. As the resistance wings 422 are connected obliquely to the rotation shaft, the diffusion part 42 is rotated by the downward movement of water.

Furthermore, the resistance wings can be made of mesh. The net body is formed of a plurality of vertical holes. In particular, as shown in the drawing, in consideration of the rotational direction of the diffusion part 42, the netting portion 422a may be formed in the terminal portion 422b, instead of forming a netting body.

The terminal portion 422b formed of the mesh 423 has a portion of the descending water passing therethrough or surface resistance to increase the turbulence. The tip portion of which the net is not formed can easily cut the water so that the diffusion portion can be easily rotated. In addition, the structural rigidity of the resistance wing is increased.

Referring to the drawings will be described the operation of the overflow sump fish tank according to an embodiment of the present invention.

The extension part 10 is installed in the water tank B of which the upper part is opened, the appropriate filtering means is installed in the processing tank 2, and the discharge part 12 of the extension part 10 and the processing tank 2 are connected. do. At this time, if the extension portion 10 is further provided with a guide portion 13, it is possible to easily connect the extension portion 10 and the treatment tank 2 by inserting the guide portion 13 into the treatment tank (2). have. Moreover, after installing the collection | recovery part 3 which connects the processing tank 2 and the water tank B, the water tank B and the processing tank 2 with which the extension part 10 was attached are filled with water.

When the recovery unit 3 is operated, water in the treatment tank 2 flows into the water tank. The water level of the water tank begins to exceed the discharge part 12 of the extension part 10 by the inflowed water, and the water which overflowed to the discharge part 12 flows into the treatment tank 2 again. Water introduced into the treatment tank 2 is purified by passing through the filtration means 22 as shown in FIG. 6 and then recovered by the recovery unit 3 to the water tank B.

If it is necessary to replace the filtration means or return water after a certain period of time, the operation of the recovery unit 3 is stopped and the recovery unit 3 is separated. In addition, while removing the guide portion 13 from the treatment tank 2, the treatment tank 2 and the water tank B are separated. Thereafter, the filtering means contained in the treatment tank may be replaced or the water of the treatment tank may be replaced. In this way, the treatment tank (2) and the water tank (B) can be easily separated, and there is no need to deal directly with the water inside the water tank, thus increasing the convenience of maintenance of a fine soil-covered water tank and the like.

In addition, in the present invention, since the water tank and the treatment tank are installed on substantially the same plane, the area occupied by the conventional vertical sump tank can be reduced. There is no need to install a dedicated angle or furniture to form a space to place the treatment tank in the lower part of the tank. In addition, the use of overflow has the advantage of blocking the noise of air bubbles generated at the top dead center of the inverted U-tube.

If the flow rate reduction part 4 is further installed, the problem of dirt or fine sand installed on the floor being overcome by the water flow discharged from the flow pipe 32 can be solved.

The diffusion part 42 provided in the flow rate reduction part 4 is rotated while being rotated by the water discharged from the flow pipe 32 to reduce the moving speed of the water. Further, the outlet 41a of the diffusion case 41 deforms the direction of the water discharged from the flow pipe 32 to be substantially parallel to the surface of the water so that the introduced water does not directly contact the bottom of the water tank. In addition, since the area of the outlet 41a of the diffusion case 41 is larger than the cross-sectional area of the flow pipe 32, the flow rate of the water discharged from the flow rate reduction part 4 can be greatly reduced.
