Hereinafter, with reference to the accompanying drawings, the bottom of the debris removal apparatus of the multi-stage culture tank according to an embodiment of the present invention will be described in detail.

The present invention relates to a device for removing debris that accumulates on the bottom of a tank for a variety of aquatic life, such as marshmallow, beating, and will be described below a case of cultivating a plunger.

As shown in Figures 1 to 5, the floor debris removal device 1 proposed by the present invention is disposed on the bottom of the water tank (3) by spraying the compressed air in the bottom direction to the first accumulated debris on the floor An injection section 5 separating from the bottom; Bubble supply portions (7, 9) for separating the floating debris separated from the bottom by the injection portion (5) to the water surface by the air bubble secondary; A filter mat (10) for discharging to the outside after moving the surface of the surface floating in the third sliding method; And a reservoir 12 for storing the discharged debris.

In the bottom debris removing device 1 having such a structure,

The inside of the water tank 3 is formed with a constant volume of space, and the water is filled to create an environment that can be cultured.

In addition, the jetting unit 5 is disposed at the bottom of the water tank 3 so that the debris accumulated on the bottom by compressed air can be separated from the bottom.

The injection unit 5 is a pair of main supply pipe 14 which is arranged to be spaced apart at regular intervals on both sides of the floor to be a passage of air; A plurality of auxiliary supply pipes 15 disposed between the pair of main supply pipes 14 to supply air; It is disposed below the auxiliary supply pipe 15 includes a plurality of injection nozzles 17 for injecting air to the floor.

The pair of main supply pipes 14 are connected to an air compressor (not shown) to be a passage for inflow of compressed air. These main supply pipe 14 may be disposed on both sides of the bottom of the water tank 3, respectively, or may be disposed on only one side. The arrangement structure of the main supply pipe 14 can be appropriately selected according to the environment of the water tank 3.

In addition, the plurality of auxiliary supply pipes 15 may be disposed between the main supply pipes 14 so that compressed air supplied through the main supply pipes 14 may flow in. At this time, since the auxiliary supply pipe 15 is disposed above the main supply pipe 14, the auxiliary supply pipe 15 is separated from the bottom of the water tank 3 by a predetermined distance.

In addition, the plurality of injection nozzles 17 disposed below the auxiliary supply pipe 15 protrude toward the bottom to inject the compressed air supplied through the auxiliary supply pipe 15 to the floor.

In this case, the injection nozzle 17 may be arranged at various angles, but preferably, the injection nozzle 17 is disposed at an angle having a good injection efficiency, for example, at a 45 degree angle.

Therefore, the compressed air injected from the injection nozzle 17 can collide with the bottom of the water tank 3 to separate the debris accumulated on the bottom from the bottom.

Then, the separated debris is suspended in the water by buoyancy, is collected by the bubble supply (7, 9) to rise to the water surface.

These bubble supply parts 7 and 9 form an air bubble in water, and when the air bubble rises due to buoyancy, the bubble is also collected and moved to the surface by an air lift method that rises to the surface together.

In more detail, the bubble supply parts 7 and 9 include: a tubular body 9 arranged to be inclined in water; An air hose (7) for supplying air to the lower part of the tube (9) to form an air bubble; And a blower (not shown) for supplying air to the air hose 7.

The tubular body 9 is arranged to be inclined, one side corresponding to the lower part is disposed away from the bottom of the water tank 3 by a predetermined distance, and the other side corresponding to the upper part protrudes to the upper part of the water surface.

And the discharge port 8 of the air hose 7 is arrange | positioned in the lower adjacent position of the tubular body 9. At this time, the air hose 7 may be injected into the air by being connected to the blower.

Therefore, the air supplied through the air hose 7 is discharged to the outside through the discharge port 8, the discharged air forms an air bubble in the water.

Then, the formed air bubble rises through the inclined tube 9 and disappears into the atmosphere outside the water surface.

At this time, when the air bubble is formed and rises through the tubular body 9, water flow is formed in the water direction inside the tubular body 9.

Therefore, the dregs floating in the lower adjacent position of the tubular body 9 rises to the surface along the inside of the tubular body 9 through this water flow, and is raised by being collected by the air bubble. At this time, since the air bubble is spherical, the surface area is wide, so that a considerable amount of debris can be collected.

The debris that rises out of the water through the tube body 9 is dropped by gravity and discharged to the filter mat 10.

The filter mat 10 sequentially transfers the dregs dropped from the tubular body 9 to the edge of the water tank 3 in the storage tank 12 direction. When the filter mat 10 is a plate-like plate, when the residue is stacked on the upper surface thereof, the filter mat 10 is transferred by the water falling from the tubular body 9 so that the stacked residue gradually moves in the rim direction of the water tank 3.

Then, when the edge of the water tank 3 is reached, it can be stored in the storage unit by falling from the top of the stacked waste.

At this time, the filter mat 10 has been described as a plate-like plate, the present invention is not limited thereto, and may be variously modified.

For example, it may be formed of a curved plate. That is, the curved plate which has a constant curvature from the pipe body 9 direction to the edge direction of the water tank 3 is also possible.

In the case of the curved plate as described above, the frictional force acts less than the flat plate, and thus it can be moved more easily.

On the other hand, according to another embodiment of the present invention, according to the degree of turbidity caused by the residue floating in the water according to the degree of generation of the air bubble and the amount of air injection from the injection portion 5 disposed on the bottom properly discharge the waste more effectively can do.

In more detail, another embodiment of the present invention, as shown in Figure 6, the turbidity detection sensor 20 which is mounted inside the water tank 3 can measure the turbidity of the water; A calculation unit 22 for calculating turbidity according to the signal transmitted from the turbidity detection sensor 20; An air bubble adjusting module 24 which transmits a signal to the blower according to the turbidity calculated by the calculating unit 22 and adjusts the air supply to adjust the generation amount of the air bubble; In accordance with the turbidity calculated by the calculation unit 22 includes an air injection amount control module 26 for controlling the amount of air injected to the floor by transmitting a signal to the air compressor to adjust the amount of compressed air.

The operation unit 22, the air bubble control module 24, and the air injection amount control module 26 are electronic devices such as a microprocessor, and include an arithmetic logic operator, registers, program counters, command decoders, control circuits, and the like. It can be configured to retrieve and decipher the instructions stored in the main memory, execute the decrypted instructions, and automatically perform the function of saving the execution result back to the main memory, and also exchange data with the input / output devices. Can be.

The calculation unit 22, the air bubble control module 24, the air injection amount control module 26, as described above, when the commands related to the determination of the air supply amount and the compressed air amount is inputted as well as control systematically in a predetermined order as well as control Provide a signal.

In more detail, when the air is blown to the bottom of the water tank 3 to remove the debris, when the turbidity detection sensor 20 mounted in the water tank 3 transmits a signal to the operation unit 22, the operation unit 22. ) Determines whether the turbidity level is appropriate.

If it is determined that the reference value is more than the float is separated from the floor in the case of a lot of air by increasing the output of the blower by the air bubble control module 24 increases the amount of air supplied through the air hose (7). In addition, when the air supply is increased, the amount of air bubbles is also increased, so that a large amount of debris can be floated to the surface in a short time, and thus it can be efficiently processed.

And, if the turbidity is less than the reference value, it is determined that the clear water is less floating on the bottom, despite the debris removal process.

Accordingly, the calculation unit 22 transmits a signal to the air compressor by the air injection amount adjusting module 26 to adjust the amount of compressed air to increase the intensity of air injected to the bottom, thereby spraying the bottom of the water tank 3 with a stronger force. Be sure to Thus, more debris can be separated from the bottom and floated.

Hereinafter, the process of removing the debris by using the debris removal device of the bottom of the multi-water culture tank according to an embodiment of the present invention will be described in more detail.

As shown in Figures 1 to 4, when removing the residue of the bottom of the water tank (3), first by operating the air compressor of the injection section 5 to supply compressed air through the main and auxiliary supply pipe (15).

The compressed air flows through the auxiliary supply pipe 15 and then is injected in the bottom direction through the plurality of injection nozzles 17. At this time, since the injection nozzle 17 is sprayed in a state of maintaining a 45 degree angle with the floor, the residue accumulated on the floor can be separated first.

Then, the debris separated from the bottom rises by buoyancy and then floats inside the water tank 3, thereby rising to the water surface by the bubble supply parts 7 and 9 secondly.

That is, by operating the blowers of the bubble supply parts 7 and 9, air is supplied through the air hose 7 and then discharged through the discharge port 8.

The discharged air forms an air bubble. At this time, since the discharge port 8 of the air hose 7 is adjacent to the mouth side of the tube body 9, the air bubble rises through the tube body 9 to form water flow.

Therefore, the debris floating in the water tank 3 rises to the surface along the water flow formed by this air bubble.

At this time, the debris may be raised like the air bubble by being collected in the air bubble.

In this way, the air bubble that has risen along the tube 9 is extinguished into the atmosphere outside the surface of the water. Then, the residue that rises out of the water through the tubular body 9 falls to the filter mat 10 in a third order.

The dregs dropped on the filter mat 10 are sequentially transferred to the edge of the water tank 3, and when the edges of the water tank 3 are reached, they can be stored in the storage unit by falling from the top of the stacked waste.

By repeating the process of the first to third steps in this way it is possible to efficiently remove the residue deposited on the bottom of the multi-culture tank. The removed debris can be used as manure or fertilizer.

On the other hand, in the case of treating the residue by the same method as in the present invention, the treated residue and the efficiency when only treated by the filter is shown in the graph below.

That is, after two weeks of culture in the tank 3, the total residue generated is 3.2 g dry matter / tank (3).

And, as a result of removing the residue by the debris removal device (1) for 4 days, as shown in Figure 5 (a), in the overflow method of the present invention 2.7 ± 0.17 g was removed, only 0.8 ± 0.09 g in the filter Leftovers were removed.

Therefore, it can be seen that the overflow method such as the present invention can remove more debris.

And, as shown in Figure 5 (b), when comparing the residue removal efficiency, the inventors of the overflow method was removed 83.6 ± 5.17%, only 25.6 ± 2.86% was removed in the filtration method. Therefore, also in the removal efficiency, it can be seen that the overflow method like the present invention has a higher removal efficiency than the filtration method.
