DETAILED DESCRIPTION

[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0032] See also Figure 1 and Figure 2 The embodiment of the present invention discloses a box-type breeding system, which includes a box body, a fish pond 1 and a new water treatment system, and may also include an automatic monitoring system.

[0033] The box body (not shown in the figure) can be a container, for example, a 40-foot dry cargo container or a 20-foot dry cargo container, or a 40 / 20-foot refrigerated container. The box body can also be assembled from a steel structure and a rock wool board. An insulation layer is provided in the box body for heat preservation. The insulation layer can be a rock wool board, or a 30-100mm thick polyurethane layer sprayed in the box body, but is not limited to this. A number of holes are provided around and at the ends of the box body for connecting external power lines and pipelines. In general, the box body is at least larger than 1 meter × 1 meter × 1 meter in size, its height can be about 2 meters, and the internal area is about 40 square meters.

[0034] The fish pond 1 is located in the box, and the fish pond 1 may include an external frame, an intermediate liner located in the external frame, and a canvas bag located in the intermediate liner. The horizontal cross-section of the fish pond 1 may be a square or a rectangle. When the horizontal cross-section of the fish pond 1 is a square, multiple fish ponds may be arranged side by side in the box. When the horizontal cross-section of the fish pond 1 is a rectangle, it may be arranged as a larger fish pond in the box, and a water inlet pipeline is provided at each of the four corners of the fish pond 1. The specific structure and layout of the fish pond 1 are not limited.

[0035] A water inlet pipe 2 and a water outlet pipe 3 are provided in the fish pond 1. The water inlet pipe 2 includes a vertical jet pipe 22 located in the fish pond, and may further include a transverse jet pipe 21 perpendicular to the vertical jet pipe 22. The transverse jet pipe 21 and the vertical jet pipe 22 are close to the inner wall of the fish pond 1, the transverse jet pipe 21 is parallel to the bottom surface of the fish pond 1 and one of the side surfaces of the box 1, and the vertical jet pipe 22 is perpendicular to the bottom surface of the fish pond 1. The transverse jet pipe 21 and the vertical jet pipe 22 are both provided with a plurality of micropores for spraying water into the fish pond 1 and forming a vortex in the water in the fish pond 1. The transverse jet pipe 21 and the vertical jet pipe 22 spray water in the horizontal direction.

[0036] A plurality of water inlet pipes may be provided in the fish pond 1, and the vertical jet pipes 22 of at least four water inlet pipes 2 define a quadrilateral area in the fish pond 1, and the quadrilateral area is preferably a square area. And the vertical jet pipes 22 of the four water inlet pipes 2 can spray water in a uniform clockwise direction to form the vortex in the quadrilateral area. For example, when the horizontal cross-section of the fish pond 1 is a square, the four corners of the fish pond 1 are all provided with water inlet pipes 2, and at this time the entire bottom inner surface of the fish pond 1 is the quadrilateral area defined by the vertical jet pipes 22, and at this time the quadrilateral area is a square area. The horizontal jet pipes 21 and the vertical jet pipes 22 of the four water inlet pipes spray water in a uniform clockwise direction, which means that water is uniformly sprayed in a clockwise direction or a counterclockwise direction. It should be noted that the arrangement mode and angle of the horizontal jet pipe 21 and the vertical jet pipe 22 are not limited, as long as both can form a stable vortex in the fish pond 1. In the present invention, the horizontal jet pipe 21 is located at the upper part of the fish pond 1, and the vertical jet pipe 22 is located at the upper and middle parts of the fish pond 1, thereby making the vortex water flow speed in the fish pond 1 different at the top and bottom, and the water flow speed in the upper part of the fish pond 1 is faster, which is conducive to the suspended matter sinking from the upper part of the fish pond 1 to the bottom.

[0037] When the horizontal cross section of the fish pond is rectangular, water inlet pipes can be arranged at the four corners and the middle of the two long sides of the fish pond, and the vertical jet pipes of the water inlet pipes define two or three or even more quadrilateral areas in the fish pond, and each of the quadrilateral areas is provided with a water outlet pipe. In this way, vortices equal in number to the quadrilateral areas are formed in the fish pond, and the quadrilateral area where each vortex is located is roughly close to a square, which is more conducive to the formation of vortices.

[0038] The water outlet pipeline 3 includes a water outlet pipe 31 located in the box body and a reverse bottom plate sucker 32 connected to the water outlet pipe 31. The reverse bottom plate sucker 32 is located at the bottom center of the fish pond, the opening of the reverse bottom plate sucker 32 faces downward, and there is a gap between the reverse bottom plate sucker 32 and the bottom inner surface of the fish pond 1. The gap value is preferably between 10-100 mm, but is not limited thereto.

[0039] like Figure 2 As shown, the outlet of the water outlet pipe 31 provided on the fish pond 1 is preferably located in the middle of the fish pond 1, so that the water in the fish pond 1 can automatically flow out from the water outlet pipe 31. An electric valve that automatically closes when a power outage occurs can be connected to the water outlet pipe 31 so that the water in the fish pond 1 will not flow out when a power outage occurs.

[0040] The water treatment system is connected to the water inlet pipe 2 and the water outlet pipe 3 to purify the water in the fish pond 1. The water treatment system includes a solid-liquid separator 4, a microfilter 5, an ultraviolet sterilization device 6, a biological filter 7, an oxygenation device 8 and a collection device 9, and also includes a water pump 10 for pumping water. The water in the water outlet pipe 3 first flows to the solid-liquid separator 4, and the solid-liquid separator 4 physically separates the suspended matter such as feces in the water. The suspended matter collected by the solid-liquid separator 4 is transported to the collection device 9. The collection device 9 can be a structure such as a filter basket or a filter mesh, which filters the suspended matter out of the sewage, and the remaining sewage flows to the sewage pipe 11. The microfilter 5 is a rotary drum microfilter with an automatic backwash system, and the water flowing out of the solid-liquid separator 4 is filtered twice by the microfilter 5. The suspended matter with smaller particles in the water in the microfilter 5 is separated more efficiently, and the separated suspended matter is also transported to the collection device 9 for collection.

[0041] The microfilter 5 is located above the biofilter 7. A part of the water in the microfilter 5 flows directly into the biofilter 7 by gravity, and the other part enters the biofilter 7 after the ultraviolet sterilization of the ultraviolet sterilization device 6. The ultraviolet sterilization device can be a flow-through ultraviolet sterilization lamp, which can be placed in front of the biofilter 7 or behind the biofilter 7. The biofilter 7 is a multi-stage flow-through biofilter, which is provided with a fluidized bed biofilter and a fixed bed biofilter. The biofilter 7 aerates the water internally and removes ammonia nitrogen. The biofilter 7 can be connected to an aeration fan 12 for aeration. The suspended matter collected by the biofilter 7 is also transported to the collecting device 9.

[0042] After the water flowing out of the biofilter 7 is pumped by the water pump 10, a part of the water is oxygenated by the oxygenation device, and then flows into the fish pond from the oxygen-enriched water inlet of the fish pond 1, and the other part directly flows into the horizontal jet pipe 21 and the vertical jet pipe 22 in the fish pond. The oxygenation device may include an oxygenation cone and a ceramic nano oxygenation disk. When the system works normally, the oxygenation cone can meet the oxygenation requirements. When the system is powered off, the oxygenation cone does not work. At this time, the gas circuit of the oxygen cylinder 13 is automatically started by controlling the solenoid valve, and the oxygen cylinder 13 is used to supply oxygen to the ceramic nano oxygenation disk for emergency oxygenation.

[0043] The automatic monitoring system can automatically monitor the fish pond, which may include a timing controller, an intelligent switch, a water quality monitoring system, a video monitoring system, an overflow protection system, etc.

[0044] In the box-type culture system of the present invention, after water enters the horizontal jet pipe 21 and the vertical jet pipe 22, an impact effect will be generated in the fish pond 1, so that the water in the fish pond 1 will produce a persistent and stable vortex structure. The vortex structure can make the suspended matter in the fish pond 1 produce a concentration effect, and gather at the bottom center of the vortex, which is also the bottom center of the fish pond 1. Since the reverse bottom discharge suction cup 32 is located at the bottom center of the fish pond 1, the reverse bottom discharge suction cup can suck out the suspended matter when absorbing water, so as to achieve the purpose of efficiently removing the suspended matter. The box-type culture system of the present invention has a simple structure, can be directly installed in a container or other box, and after the factory production is completed, it can be directly transported to the installation site for installation. The installation process is simple and convenient, and the overall footprint is small, and there is no need to carry out operations such as digging fish ponds, etc., with small investment and quick results, and waste containers can also be reused, which has good social benefits.

[0045] The exemplary embodiments of the present invention are specifically shown and described above. It should be understood that the present invention is not limited to the disclosed embodiments, but rather the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
