Description

Fish farm with bubble separator {FISH FARM HAVING BUBBLE SEPARATOR}

The present invention relates to a fish farm equipped with a bubble separator, and in more detail, it is configured to purify and discharge the sludge contained in the water by using the bubbles, thereby purifying the water. .

Hereinafter, the structure and problems of the fish farm by the background art together with the accompanying drawings will be described.

1 is a perspective view showing a fish farm according to the background art, and is described together.

In general, fish farms are pools for aquaculture developed to continuously supply people with freshwater fish or freshwater fish, and the water (saltwater or freshwater) accommodated in fish farms is mixed with the leftover fish, and the fish excrement is mixed. Since it is mixed, if left unattended for a long time, the pollution of water is increased, so the amount of dissolved oxygen decreases, causing the death of fish. In addition to this, since it becomes a hotbed of germs, a phenomenon in which fish are killed by diseases occurs.

Therefore, in the background art, the following farming site 1 is proposed.

A breeding tank 10 in which seawater or fresh water is filled and fish is farmed is constructed, and on the side of the breeding tank 10, a solid excrement separation tank 20 in which water of the filtered breeding tank 10 is stored is configured. . And the solid waste separation tank 20 and the rearing tank 10 is arranged on the side of the solid waste separation tank 20 is supplied with water contained in the filtration tank 30 is configured to remove contaminants by microorganisms.

In addition, in the breeding tank 10, an inlet through which water is absorbed is formed on the bottom surface, and a flow path connected to the inlet and penetrating the inside of the bottom surface to extend toward the solid excrement separation tank 20 is configured. And connected to the flow path is formed a drainage hole penetrating upward of the bottom surface, a water pump connected to the drainage is configured, connected to the water pump to guide the water to the solid waste separation tank 20 The pipe 11 is constructed.

In addition, the water is moved from the solid waste separation tank 20 to the filtration tank 30, the water is moved from the filtration tank 30 to another filtration tank 30, and the last one of the filtration tanks 30 is disposed. Drainage pipes (21, 35, 45) for moving water to the breeding tank (10) are respectively disposed, and each of the drainage pipes (21, 35, 45) is equipped with an underwater pump to be configured to move water.

In addition, a drum filter 60 that is supported on both upper ends of the solid waste separation tank 20 and disposed under the drain pipe 11 is configured. The drum filter 60 is mounted to rotate on a support 50 fixed to the upper ends of both sides, and is cylindrical in shape, and the inside is emptied, and a plurality of holes for passing water are formed on the circumferential surface. And the motor is connected and configured to be rotatable.

Looking at the water purification process of the fish farm (1) by the background technology is as follows.

When the underwater pump submerged in the breeding tank 10 is operated, water (sewage) in which sludge such as feed and feces is mixed through the inlet port, through the inlet port, the flow channel, the outlet port, the pump, and the drain pipe 11 The solid waste separation tank 20 is filled. At this time, the wastewater discharged through the drain pipe 20 falls from the upper part of the drum filter 60 and passes through the hole of the drum filter 60 and enters the solid excrement separation tank 20, thereby contaminants through the hole. This is filtered. In addition, since the drum filter 60 is rotated by a motor, holes perforated in the circumferential surface are evenly used for filtration.

In this way, since the water filled in the solid waste separation tank 20 flows into the filtration tank by the drain pipe 25, fine organic matter that cannot be filtered by the drum filter 60 is removed. The number of such filtration tanks 30 can be arranged to improve the degree of water purification.

Next, one cycle is completed because the purified water is returned to the breeding tank 10 by the drain pipe 45. By repeating this cycle, water purification is possible.

However, the fish farm (1) by this background technology causes the following problems.

When the drum filter 60 is used for 2 to 3 hours, the contaminants are stacked on the circumferential surface of the drum filter 60 in a sludge shape, and thus the hole is closed, and water cannot be passed through. Therefore, the water mixed with the contaminants flows into the solid excrement separation tank 20 as it is, and such water is contaminated to the filtration tank 30 more than the prescribed level, and thus the filtration function can no longer be handled. Therefore, as the time elapses, the concentration of contaminants in the breeding tank 10 increases, and thus, there is a serious problem in that the death of fish raised and raised for a long time cannot be avoided.

Therefore, the operator must replace the drum filter 60 with a new one after collecting it, and the collected drum filter 60 has a series of hassle that needs to be repaired so that it can be reused through washing. There is a problem that it is practically impossible to periodically perform this operation every 2 to 3 hours.

In addition, due to such maintenance work, a large number of manpower must be resident, which increases the labor cost and increases the production cost.

In addition, the drum filter 60 is often occluded, so it cannot function properly and the maintenance is cumbersome, so the drum filter 60 is mostly left as it is. Therefore, in order to save fish, there is a problem in which a large amount of oxygen is supplied to the breeding tank 10, and there is a problem in that the production cost is increased.

Explain.

In general, the fish farm is filled with water (W), such as sea water or fresh water, and a breeding tank 110 in which fish are farmed is formed. On the side of the breeding tank 110, solid excrement, that is, sediment of feed or fish excrement is settled. The mixed sludge (S) is composed of a solid waste separation tank 120 in which the water (W) of the breeding tank 110 is filtered.

And the solid waste separation tank 120 and the rearing of the breeding tank 110 are supplied with water (W) accommodated in the solid waste separation tank 120 to remove contaminants by microorganisms a number of filtration tank 130 It is composed.

In addition, in the breeding tank 110, a plurality of drains 113 through which water (W) is absorbed is formed on the bottom 111, and connected to each of the drains 113 to sideward the inside of the bottom 111. A drainage pipe 140 that penetrates into and extends toward the solid waste separation tank 120 and is drawn out above the bottom 111 of the solid waste separation tank 120 is constructed. At this time, since a plurality of drain ports 113 and drain pipes 140 are configured, water in the water tank that can be filtered can be increased, so that a large capacity of the breeding tank 110 can be achieved.

In addition, the water (W) is moved from the solid waste separation tank (120) to the filtration tank (130), the water (W) is moved from the filtration tank (130) to another filtration tank (130), and among the filtration tank (130) Drain pipes 400, 500, and 510 are respectively disposed to move water W from the last disposed one to the breeding tank 110, and submersible pumps U, V are disposed in each of the drain pipes 400, 500, 510. , R) is mounted and configured to move water.

Since the bottom 111 is formed to be inclined downward toward the drain 113, the sludge S in which the settled feed or fish excrement is mixed is easily accommodated. In addition, the water pump connected to the drain pipes 400 and 500 is configured to pump water in a state accommodated in each of the solid waste separation tank 120 and the filtering tank 130.

The fish farm 100 equipped with a bubble separator according to the present invention is equipped with a bubble separator 160 in the drainage pipe 140 in the configuration of the fish farm, so that it is accommodated in the solid waste separation tank 120, so that the breeding tank Characterized in that configured to generate air bubbles in the water (W) of the breeding tank 110 introduced by the water pressure or water level of the water (W) accommodated in (110) to float the sludge (S) upwards to discharge. .

To this end, the bubble separator 160 is configured as follows.

The guide pipe 161 is configured to be connected to the drain pipe 140 so that the water (W) of the breeding tank 110 is introduced, and connected to the guide pipe 161 and vertically erected and opened upward and water surface The purification tank 162 is formed so as to extend upward of (L). As an example, the purifying container 162 may have a pipe shape and a lower end may be blocked.

In addition, the overflow pipe 163 connected to the side of the purification tank 162 and extending upwardly of the water surface L so as to be disposed below the connection point G of the guide pipe 161 in the purification tank 162. ) Is composed. The upper end of the overflow pipe 163 is configured to be lower than the upper end of the purification tank 162. In addition, the upper end of the overflow pipe 163 is configured to be lower than the water surface (L) of the breeding tank 110. Therefore, the water (W) of the breeding tank 110 is configured to be discharged to the solid excrement separation tank 120 through the overflow pipe 163 due to the water level difference.

In addition, in the purification tank 162, an air pipe 165 connected to a connection point G of the guide pipe 161 and a connection point H of the overflow pipe 163 is configured to supply air. do. It goes without saying that the air pipe 165 is in a state that has passed through the overflow pipe 163 and is closed so that no leakage occurs at the point where the air pipe 165 penetrates. In addition, the air pipe 165 is configured such that an air pump is connected by a hose (not shown) to supply air. In addition, an air stone 166 accommodated in the purification tank 162 and connected to the air pipe 165 is configured. The air stone 166 is disposed between both connection points (G, H), so when bubbles are generated, it is configured to supply purified water (W) to the overflow pipe 163.

In addition, the discharge hose 168 is connected to the upper portion of the purification tank 162, extending to the outside of the breeding tank 110, to guide the sludge (S) to the outside.

Looking at the water purification process of the fish farm 100 equipped with a bubble separator of the present application by the above configuration is as follows.

As shown in FIG. 7, the water (W) charged in the breeding tank 110 is water pressure due to a difference in water level, and the water (W) of the breeding tank 110 is coupled with the sludge (S) through the drain 113. Inflow. And it is fed to the guide pipe 161 through the drain pipe 140. Next, it flows into the purification tank 162 through the guide pipe 161. Then, the water (W) is filled in the overflow pipe 163 while being filled in the purification tank 162.

In this state, when air is injected through the air pipe 165, a large amount of air bubbles are generated through the air stone 166 and float upward. Then, as shown in FIG. 7, various sludges S included in the water W float upward by bubbles.

At this time, when the amount of water (W) filled in the purification tank 162 increases and the water surface (M) exceeds the upper end of the overflow pipe 163, as shown in FIG. 8, water through the overflow pipe 163 (W) is drained and supplied to the solid waste separation tank 120. In this case, the water W to be drained is in a state where the sludge S is removed. This is because the water surface (M, E) of the purifying tank 162 and the overflow pipe 163 is always in the same state by atmospheric pressure. This phenomenon is easily understood by the movement of water due to the water level difference because the water surface (L) of the breeding tank 110 is higher than the water level of the water (W) charged in the purification pipe 162 and the overflow pipe 163. have. Since these principles are general, detailed descriptions are omitted. In addition, since the airstone 166 is disposed between the connection point G of the guide pipe 161 and the connection point H of the overflow pipe 163, the overflow disposed below the airstone 166 Sludge (S) filtered water (W) is introduced into the inlet of the pipe (163).

In addition, since the upper end of the overflow pipe 163 is lower than the upper end of the purification tank 162, and the upper end of the purification tank 162 is higher than the water surface L of the breeding tank 110, water through the overflow pipe 163 ( Even if W) is drained, the height is adjusted so that it is not discharged through the purification tank 162.

Therefore, when the water surface M of the purification vessel 162 exceeds the upper end of the overflow pipe 163 by water pressure, the water W is drained through the overflow pipe 163, so that the purification vessel 162 The water surface (M) of the overflow pipe 163 becomes lower than the top, and at the same time, the water (W) of the breeding tank 110 is supplied by the water pressure, so that the water surface (M) of the purification tank 162 overflows. When the upper end of the pipe 163 is exceeded, the purified water W is drained through the overflow pipe 163. This action is continuous. In this way, as time passes, the sludge S suspended and stacked on the water surface M of the purification vessel 162 overflows the upper end of the purification vessel 162 by the water pressure of the incoming water W, so the discharge hose ( 168) is discharged to the outside of the breeding tank 110.

In this way, the water received in the solid waste separation tank 120 flows into the filtration tank 130 through the drain pipe 400, and the water in the filtration tank 130 is transferred to the other filtration tank 130 by the drain pipe 500. Organic matter that is introduced and cannot be filtered through the bubble separator 160 is sequentially removed by microorganisms. Next, the water (W) of the last filtration tank 130 is returned to the breeding tank 110 by the drain pipe 510. As described above, according to the present invention, the water (W) accommodated in the breeding tank 110 is continuously returned to the breeding tank 110 through the solid excrement separation tank 120 and the filtration tank 130, so that the water (W) is continuously Purifies. Through this process, water (W) of the existing breeding tank 110 can be circulated and reused without adding a separate water, so it is efficient in terms of reuse of water (W).

The filtration tank 130 is a general matter and can be understood by anyone skilled in the art, so a detailed description thereof will be omitted.

According to the present invention as described above, as in the background art, it solves the problem of not being able to properly purify water as a drum filter and the trouble of frequently replacing and repairing the drum filter in order to solve the above problem, thus improving work efficiency in the aquaculture industry. Improve it.

That is, as the drum filter is formed by winding the screen in a cylindrical shape, the phenomenon that the screen is frequently blocked does not occur in the present application. In other words, since the present application separates the sludge (S) from the water (W) by using continuously generated air bubbles, it is possible to reduce the production cost because the manpower resident for maintenance can be reduced compared to the background technology.

In addition, since the water in the breeding tank 110 can be efficiently and continuously filtered, the amount of oxygen supplied to the breeding tank 110 can be reduced compared to the background technology, thereby reducing the production cost compared to the background technology. In other words, in the background technology, it is cumbersome to replace the drum filter, and the contaminated water is left unattended. As a result, the amount of dissolved oxygen is insufficient. However, according to the present invention, since the water purification efficiency is improved, the amount of oxygen injected can be reduced compared to the background art, thereby reducing the production cost.

In addition, since water (W) is supplied to the bubble separator 160 by water pressure, a pump is not used to feed the water (W), thereby preventing a waste of energy. Of course, energy is used because air is injected through the air pipe 165, but an economical burden is compared to using a pump for circulating water because a small amount of air pump can sufficiently float the sludge (S). Insignificant That is, water (W) may be filtered through the bubble separator 160 without power.

In addition, since water can be efficiently purified compared to the background art, it can be recycled and used without supplying water to a breeding tank, thereby reducing the overall cost of supplying new water.

In addition, by constructing a large-capacity breeding tank 110 provided with a plurality of drainage ports 113 and a drainage pipe 140, the size of the breeding tank is changed from the conventional small-capacity breeding tank to the growth of fish, etc. Since fish are frequently moved, it is possible to prevent the economic loss of fish.
