Conventionally, a tank having a single-layer structure or a concrete tank was installed on the floor of the room, and there was an aquaculture device (Patent Registration No. 10-0026548) such as shrimp, and the tank of the aquaculture device had a lot of heat loss, A large area is required in order to do so, so that a large installation cost and maintenance cost are increased, resulting in very uneconomical problems.

In addition, when sediments such as shells and excreta from the shelling process are accumulated on the floor, they are decayed and ammonia gas is generated. Therefore, since crustaceans are killed, it is necessary to remove the sediment from time to time so as not to accumulate on the floor. However, there are problems such as the fact that the productivity has been greatly decreased and the waste of the cost has been incurred due to the loss caused by the inability to be removed on time due to these points,

In addition, there has been a problem in that it is not suitable for large-scale production of crustaceans because the crustaceans are bombarded and burnt when they are gathered in a state in which the fragile body is exposed as it is.

FIG. 4 is a plan view showing a part of the crustacean form system shown in FIG. 1, and FIG. 5 is a front view showing a part of the crustacean form system shown in FIG. 1, and FIG. 6 is a front view to be.

1 to 6, a crustacean culture system according to the present invention includes a water tank 10, a plurality of multi-layer frames 20 installed inside the water tank, and a plurality of mesh plates 30 An air feeder 40 for supplying air to the seawater contained in the water tank, and a sediment remover 50 for removing sediment accumulated on the bottom of the water tank.

The water tank 10 is a rectangular box with an opened upper surface, and may be provided as a single layer, but it is provided with two to three or more layers rather than a single layer.

When the water tanks 10 are provided in a plurality of layers, the columns 13 are arranged at regular intervals so that the upper end of the four-sided wall 11 of the lower layer and the lower surface 12 of the upper layer are isolated at a predetermined interval, So that the lower-layer water tank can be maintained at a predetermined interval.

The surface heating element 14 is laid on the four side walls 11 of the water tank 10 so that the temperature of the seawater accommodated therein is maintained at 20 to 30 ° C suitable for the culture of crustaceans under the control of a general automatic thermostat.

The water tank 10 further includes a supply pipe 15 for supplying fresh seawater at the beginning and of course as needed and a drain port 16 for discharging seawater when replacing part or all of the seawater or cleaning the inside of the water do.

The multi-layer frame 20 is constituted by a plurality of stacking benches 22 which are horizontally attached by horizontally crossing at regular intervals between the vertical bars 21 of four corners and the lower and upper ends of the four corners of the vertical bars And is formed as a rectangular body capable of stacking the mesh plate members 30 one by one.

In addition, the multilayer frame 20 includes an intermediate vertical bar 23 installed vertically across the middle of any one of the four side faces open by the four-corner vertical bar 21, And a plurality of support rods (24) attached to the upper surface of the stage (22) so as to be spaced apart from each other by a predetermined distance.

Therefore, when the mesh plate members 30 are stacked one by one on each layer stacking table 22 of the multi-layer frame 20, any one of the four surface portions on which the intermediate vertical bar 23 is not provided, And the upper and lower surfaces of the corresponding portions of the retention members are interposed between the upper surface of the loading table and the lower surface of the support, and the outer surface is supported by the inner surface of the middle vertical frame and pushed to one side And is prevented from being generated or exhaled.

The multi-layer frame 20 is provided in a plurality of rows in the front and back and right and left depending on the size of the water tank 10. For example, the multi-layer frame 20 is provided in three rows in the front and rear, The front and rear ends of the four side walls 11 may be separated from each other by the same interval as the front and rear walls of the four side walls 11, respectively.

When the partition wall 17 is provided, the inside of the water tub 10 is divided into left and right side portions 10A through which the front and rear sides communicate with each other with the partition wall as a boundary, A passage through which seawater circulates in the water tank when air is injected is formed.

The mesh plate member (30) is formed of a rectangular frame (31) and a net (32) to which the edges are bound by the frame.

These netting members 30 are attached to each of the stacking bases 22 which are horizontally attached to each other at regular intervals between the lower end and the upper end of the multilayer frame 20, So as to be installed in a multi-layered structure.

The mounting state is stabilized because each of the mesh plate members 30 is placed on the mounting table 22 in a state in which a part of the upper surface of the frame 31 is supported on the lower surface of the support table 24. In this state, The feeding of the crustaceans allows them to feed.

In addition, a support bar 25 for supporting the middle of the lower surface of the mesh plate member 30 is provided on the mount table 22 to support the lower surface of the mesh plate member, so that the middle of the mesh plate member is struck downward It is also preferable to prevent deformation from occurring.

The air supplier 40 includes an air pump 41 and an upper upper surface of the four-sided wall 11 and an upper inner side of the partition wall 17 zigzag from the discharge port of the air pump through the open top surface of the water tank 10 And an upper end connected to the air supply pipe at regular intervals, and each lower end is connected to a four-sided wall adjacent to the bottom of the water tank, and a plurality of air blown pipes vertically downwardly close to the inner surface of the partition wall. An engine (43), and a venturi (44) laid on the lower end of each of the air distribution pipes.

The air supply unit 40 discharges the cleaned outside air into the water through the venturi 44 installed adjacent to the inner bottom of the water tank 10 to supply oxygen to the stored seawater, To circulate at an appropriate flow rate.

The sediment remover 50 includes a decelerating motor 51, a driving shaft 52 rotated by the decelerating motor, a sediment removing cylinder 53, and a pulling wire 54 connecting the sediment removing / .

The driving shaft 52 is disposed between the front wall of the four side walls 11 of the water tub 10 and the front end of the front plate member 30 so as to intersect the left and right side walls, And the deceleration motor 51 is installed on one of the left and right sides of the drive shaft and is provided as a bracket on the upper end of one of the left and right side walls.

When the sediment removing tank 53 descends from the inside of the water tub 10, the sediment removing tub 53 is seated on the bottom of the receiving unit 18, which is recessed laterally in proportion to the size of the sediment removing tub, So that the top is collinear with the bottom.

The sediment eliminating cylinder 53 is formed by bundling a mesh having a size such that the mesh snow can escape only from the seawater contained in the frame, The seawater escapes and the sediment is lifted all over the surface.

In the case where the distance between the left and right side walls of the water tank 10 is large and the net plate members 30 are provided in four rows, the distance between the left and right side walls A pair of left and right spaced apart pairs are formed to be slightly shorter than the two divided intervals, so that the rising load is greatly reduced and increased smoothly as compared with a case where a single unit is formed.

The tow wires 54 are paired to the left and right, and the lower ends thereof are bound to the left and right ends of the upper surface of the sediment removing tube 53, and the upper ends thereof are bound to the drive shaft 52.

The sediment remover 50 descends so that when a predetermined amount of sediments such as crustacean shells or excreta are contained in the sediment removing tank 53 inserted in the receiving portion 18, the decelerating motor 51 is driven to be positively driven The drive shaft 52 rotates forward to allow the draw wire 54 to be wound so that the sediment removing cylinder ascends above the water surface of the seawater contained in the water tank 10 to reach a height at which sediment contained therein can be easily removed, Stop the motor.

After the removal of the sediment contained in the sediment removing tank 53 is completed, the deceleration dam 51 is reversely driven to rotate the drive shaft 52 in the reverse direction. As a result, the drawn wire 54 is loosened, And then inserted into the accommodating portion 18 to stop the decelerating motor.

The sediment remover 50 is not necessarily installed only between the front wall of the four side walls 11 of the water tub 10 and the front end of the front side net plate member 30, But may be provided either between the rear end of the wall plate and the rear end of the back plate, or both before and after the rear plate. Such a case is also within the scope of the present invention.

The sediment remover (50) periodically operates the decelerating motor (51) by controlling the manual or general automatic controller to remove sediment.

FIG. 7 is an enlarged front view of another example of a mesh plate member applied to the crustacean form system of FIG. 1; FIG.

Another example of the mesh plate member 30 according to Fig. 7 is characterized in that the mesh plate member is installed to be inclined at a predetermined angle.

The reason for this is that a part of the crustacean shell or excrement which is light in weight is not deposited on the food put on the upper surface of the mesh plate member 30 but falls smoothly into the bottom of the water tank 10 rather than the horizontal state, To about 30 [deg.].

At this time, since the supporting table 24 is located on the side where the reticle 30 is inclined and supports the corresponding part of the frame 31 together with the middle vertical table 23, the reticle 22, As shown in Fig.

When the mesh plate member 30 is inclined in this way, a part of light shells or excrements due to peeling off of the crustacean on the top surface of the mesh plate member is not accumulated on the food and smoothly falls to the bottom of the water tank 10, So that it is possible to remove the bark and the excrement without much labor and time as compared with the case where it is installed horizontally.

When crustaceans are cultured by the crustacean culture system according to the present invention, the crane members 30 are first loaded on the respective stage stacking beds 22 of the multi-layer frame 20 so as to be supported by the support rods 22, 15 so that clean sea water is sufficiently submerged to the upper portions of the mesh members 30, the surface heating member 14 is operated to maintain the temperature of the seawater at 20 to 30 ° C Feeding the food to the upper surface of the mesh plate members, feeding microorganisms that eat or decompose and remove sediments and ammonia generated by the offspring of the crustaceans to be cultured and the excrement or peeled shells of the offspring.

Then, the air supplier 50 continuously or periodically operates the air pump 51 by the control of a manual or general automatic controller to pump the purified air.

When the air pump 51 is operated, the air pumped is connected to the supply pipe at a predetermined interval via the supply pipe 42, and each lower end is connected to the four-sided wall 11 and the bottom wall of the water tank 10, The air is blown to the seawater at a predetermined pressure through the venturi (44) attached to the lower ends of the air distribution pipes (43), which are vertically downwardly adjacent to the inner surface of the partition (17).

At the same time, the venturi 44 (see FIG. 1) provided on the right side of the water tank left side wall and the left side of the partition wall, corresponding to the left side portion 10A of the water tank 10, Are provided so that air is ejected toward the rear and the inside of the left side portion and are disposed to correspond to the left side of the water tank right side wall and the right side of the partition wall at positions corresponding to the right side portion 10B of the water tank with the partition as a boundary The venturi (44) is installed such that air is ejected toward the front and the inside of the right side portion. Venturi (44a) located behind the left side portion is installed so that air is ejected toward the rear side of the right side portion, The venturi 44b located at the front of the right side is installed such that the air is blown toward the front of the left side, When the air is blown out through each of the venturi, the seawater moves from the front of the left side portion to the rear side of the right side portion due to the direction of the ventilation and the air pressure, and moves backward from the rear portion of the right side portion to the forward side of the left side portion .

Accordingly, when the air pump 51 is operated, seawater circulates counterclockwise inside the water tank 10 with the partition wall 17 as a boundary, so that not only oxygen is supplied smoothly but also the input microorganisms The water quality is maintained for a long period of time because the precipitate is dispersed and mixed evenly and quickly decomposed and removed.

Of course, the circulation rate of the seawater is such that the crustacean does not interfere with feeding activity and growth, and the sediment which is deposited on the bottom of the water tank 10 during the circulation of the seawater is counter- So that the sediment can be removed from the sediment removing tank 53. [

When a predetermined amount of precipitate is contained in the sediment removing tank 53, the decelerating motor 51 of the sediment remover 50 is driven in a positive direction so that the driving shaft 52 is rotated forward to wind the drawing wire 54, When the container is raised to a height above the water surface of the seawater contained in the water tank 10 to reach a height at which sediment contained therein can be easily removed, the deceleration motor is stopped.

Thereafter, when the sediment contained in the sediment removing tank 53 is completely removed, the deceleration dam 51 is reversely driven to rotate the drive shaft 52 in the reverse direction. As a result, the drawn wire 54 is loosened, And stops the decelerating motor when it is seated in the accommodating portion 18.

The process of removing the sediment contained in the sediment removing tank 53 by operating the sediment removing device 50 may be performed periodically or selectively as required. In this case, The water quality of the seawater is maintained for a longer period of time because the sediment that accumulates is removed quickly and is not neglected.

Since the crustacean culture system according to the present invention is installed in a plurality of layers rather than a single layer, maintenance of the crustacean culture system is very simple and easy, and the quality of seawater is maintained for a long period of time By eliminating the cause of our company, we can stabilize mass production of crustaceans, increase productivity, increase profit, and also save huge installation and maintenance costs.
