Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an aquaculture device and aquaculture system. Background Technology

[0002] Aquatic products such as fish, shrimp, and crabs are generally cultured in aquaculture devices. The upper part of the device uses aquaculture water to cultivate the aquatic products, while the excrement and uneaten feed of the aquatic products accumulate at the lower part of the device to achieve separation of waste and facilitate discharge for subsequent treatment.

[0003] Currently, to facilitate the sedimentation of manure, the lower part of aquaculture equipment is generally designed with a conical structure. For example, prior art CN217184440U discloses a recirculating aquaculture system for high-density fish farming, which uses an arc-shaped pond bottom to facilitate the sedimentation and accumulation of manure and uneaten feed. However, the angle between the tangent of the arc-shaped cross-section of the pond bottom and the horizontal line is 15-25°, resulting in a relatively small slope and slow sedimentation of manure, leading to low manure separation efficiency. Conversely, if the conical structure at the bottom of the aquaculture equipment is designed with a larger slope than the horizontal plane, although it can achieve rapid sedimentation of manure and improve the efficiency of manure separation, the overall height of the aquaculture equipment will be significantly increased, leading to limitations in applicable environments and installation. Utility Model Content

[0004] To address the aforementioned deficiencies in the prior art, the present invention aims to provide a breeding device and system that can control the height of the breeding device and efficiently separate manure and waste, making it suitable for various breeding systems.

[0027] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] See Figure 1 This utility model provides an aquaculture device, including a device body 1. The upper part of the device body 1 is a straight cylindrical section 11 for aquaculture, and the lower part of the device body 1 is a conical section 12 for manure sedimentation and separation. The straight cylindrical section 11 and the conical section 12 are connected. The conical section 12 includes at least two conical hoppers 121, which are laid flat to form the conical section 12.

[0031] The straight section 11 and the conical section 12 are arranged vertically and connected as an integral structure. The upper part of the aquaculture device is the straight section 11, which is used for aquaculture. The straight section 11 has a large internal space, which is conducive to high-density aquaculture and thus increases the aquaculture cost.

[0032] Aquatic excrement and uneaten feed will settle downwards, and the rate of sedimentation directly affects the efficiency of waste separation. The lower part of the aquaculture device is a conical section 12, which is divided into at least two cones 121. Compared to a single large cone, the at least two cones 121 have a greater slope relative to the horizontal plane to accelerate the downward sedimentation of aquatic excrement and uneaten feed, thereby improving the efficiency of waste separation. Furthermore, the height of the conical section 12 can be controlled, thus controlling the height of the aquaculture device. This allows the device to be used in both shallow and deep water areas, avoiding installation limitations and minimizing restrictions on the applicable aquaculture systems and environments. Aquaculture can be carried out in any body of water, such as rivers, lakes, or fishponds.

[0033] Furthermore, the movement of aquatic organisms within the straight section 11 disturbs the water, hindering the deposition of feces. The conical section 12 of this invention, divided into at least two conical hoppers 121, forms a stable flow zone, thereby reducing the disturbance of the water by aquatic organism movement and improving the separation of feces.

[0034] Of course, under the premise of combining actual working conditions, the more cones there are, the better the effect of stabilizing the flow, and the higher the height of the breeding device can be controlled while maintaining a large slope, so as to ensure the effect of separating manure and sewage and expand the scope of application.

[0035] The cross-section of the straight section 11 is circular, elliptical, or polygonal, and the shape of the top cross-section of the conical section 12 matches the shape of the cross-section of the straight section 11. The straight section 11 can be cylindrical. Figure 1 and Figure 6 ), elliptical prism, triangular prism, quadrangular prism ( Figure 7 The structure is in the shape of a straight cylinder, such as a pentagonal prism or a hexagonal prism, to ensure that the straight cylinder section 11 has a large internal space, which is convenient for high-density aquaculture.

[0036] The conical section 12 can be located directly below the straight section 11, such as... Figure 1 and Figure 6 As shown, the shape and dimensions of the top cross-section of the conical section 12 are adapted to the cross-section of the straight section 11. Alternatively, the conical section 12 is located below a portion of the straight section 11, as shown. Figure 7 As shown, the shape and size of the cross-section of the left side region of the straight section 11 are adapted to the shape and size of the top cross-section of the conical section 12. In summary, as long as the straight section 11 and the conical section 12 are connected and the space of the conical section 12 is sufficient for the deposition of fecal matter, the size is not particularly limited.

[0037] For the conical section 12, the conical hopper 121 includes at least one sidewall, which is connected end-to-end to form the hopper wall of the conical hopper 121. The sidewall is an inclined arc-shaped sidewall or a plate-shaped sidewall. The area enclosed by the bottom end of at least one sidewall in the same conical hopper 121 is smaller than the area enclosed by the top end. The conical hopper 121 can be of any shape, for example, a cone formed by at least one arc-shaped sidewall, or an irregular shape formed by at least one arc-shaped sidewall and at least one plate-shaped sidewall, or a pyramidal shape formed by at least three plate-shaped sidewalls, etc. Figure 4 In the first embodiment shown, the cone 121 has three sidewalls with an arcuate structure, and multiple cones 121 are arranged in a flat arrangement to form a petal-shaped cone section 12. Alternatively, as... Figure 6 In the second embodiment shown, the cone 121 has six sidewalls with an arc-shaped structure, and multiple cones 121 are laid flat to form a honeycomb-shaped cone section 12. Alternatively, as... Figure 7 In the third embodiment shown, the cone hopper 121 has four side walls with a plate-like structure, and multiple cone hoppers 121 are laid flat to form a grid structure cone section 12. Of course, in practical applications, the cone section 12 can also be designed as a grid structure, a rhomboid structure, etc., and the shape can be arbitrarily selected, as long as a large slope can be maintained, the height can be controlled, and a large number of cone hoppers 121 can be used to efficiently separate feces and sewage.

[0038] It should be noted that although aquatic organisms generally swim within the straight section 11, a very small number may swim into the conical section 12, or even to the bottom of the conical section 12, causing them to settle along with the waste or even be separated from the aquaculture unit. Therefore, such as... Figure 4 , Figure 5 and Figure 7 As shown, a baffle 122 is provided at the bottom of the cone 121. The peripheral edge of the baffle 122 is connected to the wall of the cone 121. The baffle 122 has several through holes 1221.

[0039] The shape of the baffle 122 is adapted to the wall of the cone hopper 121 to ensure a sealed connection between the baffle 122 and the wall of the cone hopper 121. The baffle 122 prevents aquatic organisms from swimming to the bottom of the cone section 12, thereby ensuring that the aquatic organisms are always kept in the aquaculture device. The manure is deposited to the bottom of the cone section 12 through several through holes 1221 on the baffle 122, so as to achieve effective separation of manure and waste.

[0040] See Figure 1 and Figure 2 The bottom of the cone 121 is equipped with a flushing port, which is located below the baffle 122 and connected to a flushing pipe 2. Prolonged accumulation of fecal matter may clog the through holes 1221, thus affecting the separation effect. The flushing pipe 2 allows water to enter the cone 121 through the flushing port, thereby flushing the baffle 122 and ensuring the unobstructed flow of the through holes 1221.

[0041] After the manure settles and separates to the bottom of each cone 121, it is discharged from the aquaculture device for further treatment. Specifically, the bottom of each cone 121 is connected to a drain pipe 3, which is located below the baffle 122. The drain pipes 3 of at least two cones 121 are directly connected to the manure treatment equipment, or are connected to the manure treatment equipment through a main pipe 4, or are connected to a drain chamber 5, with the drain chamber 5 connected to the manure treatment equipment through the main pipe 4. There is a liquid level difference between the cone 121 and the manure treatment equipment, or a power device is provided.

[0042] Taking a sewage treatment equipment as an example of a transfer tank, in the simplest case, the sewage pipes 3 of each cone 121 are directly connected to the transfer tank. Although this structure reduces the number of other components, the pipeline structure is complex. Preferably, the sewage pipes 3 of each cone 121 are connected to a main pipe 4, which connects to the transfer tank. This simplifies the pipeline structure. However, to accommodate the sewage in all cones 121, the diameter of the main pipe 4 needs to be large enough, which places high demands on the size of the main pipe 4 and makes selection inconvenient.

[0043] More preferably, such as Figure 2 , Figure 6 and Figure 7As shown, the sewage pipes 3 of each cone 121 are connected to the sewage discharge chamber 5. The sewage discharge chamber 5 is connected to the transfer tank through the main pipe 4. The main pipe 4 is located at a certain distance from the bottom of the sewage discharge chamber. In this way, after the sewage from each cone 121 is discharged into the sewage discharge chamber 5, the sewage needs to accumulate at the location of the main pipe 4 before it can be discharged into the transfer tank, which reduces the burden on the main pipe 4 and simplifies the pipeline.

[0044] The discharge of fecal waste from the cone 121 to the waste treatment equipment can be achieved using the liquid level difference, thus enabling powerless discharge and reducing energy consumption. Alternatively, a power pump can be used to extract the fecal waste and discharge it to the waste treatment equipment. Or, as... Figure 7 As shown, sewage is discharged by air lifting. The sewage pipe 3 is connected to an air inlet pipe 9, through which air is output into the sewage pipe 3, thereby lifting the sewage into the sewage discharge chamber 5. The sewage is then discharged to the sewage treatment equipment via the main pipe 4, and discharged through the air lifting outlet at the top of the sewage discharge chamber 5. Both the power pump and air lifting methods improve the efficiency of sewage discharge and prevent sewage from accumulating in the cone hopper 121 or the sewage discharge chamber 5.

[0045] In addition, see Figure 1 and Figure 4 The aquaculture device is equipped with an aeration assembly, which includes an aeration device, an oxygen supply pipe 6, and an oxygen delivery pipe 7. The oxygen delivery pipe 7 is connected to the aeration device through the oxygen supply pipe 6 and is located at the bottom of the straight section 11. Several oxygen delivery holes are provided on the oxygen delivery pipe 7. The aeration device provides oxygen to the oxygen delivery pipe 7 through the oxygen supply pipe 6, thereby increasing oxygen levels in the straight section 11 through the oxygen delivery holes of the oxygen delivery pipe 7. This aeration ensures adequate dissolved oxygen levels in the aquaculture water, which is beneficial for aquatic growth.

[0046] The oxygen supply pipe 6 is a ring structure located at the top of the straight section 11. At least two oxygen delivery pipes 7 are provided, both connected to the oxygen supply pipe 6. The density of the oxygen delivery holes on the oxygen delivery pipes 7 gradually increases from the bottom edge of the straight section 11 towards the bottom center. The ring structure of the oxygen supply pipe 6 ensures uniform oxygen supply to the oxygen delivery pipes 7. The denser density of the oxygen delivery holes in the center of the oxygen delivery pipes 7 not only allows for more even distribution of dissolved oxygen through aeration but also facilitates the separation of fecal matter and the pushing of lighter floating debris to the periphery of the aquaculture water. Thus, with outlets located around the periphery of the aquaculture device, floating debris can be discharged from the outlets, ensuring water quality. Furthermore, the large amount of aeration in the center raises the water level in the aquaculture water, making the water surface higher than the outlet, allowing water to flow from the outlet to the purification unit without power, thus reducing energy consumption.

[0047] In addition, see Figure 3A movable screen 8 is provided between the straight section 11 and the conical section 12. The screen 8 is laid flat at the bottom of the straight section 11 and is located above the oxygen supply pipe 7. The mesh size of the screen 8 needs to ensure that manure can be deposited smoothly. During the aquaculture process, the screen 8 is fixed above the oxygen supply pipe 7. When it is necessary to harvest aquatic products, the screen 8 can be lifted and moved upward to gradually reduce the aquaculture space occupied by the aquatic products, thereby driving the aquatic products to the upper part of the straight section 11 for easy harvesting.

[0048] It should be noted that the screen 8 can be fixed to the bottom of the straight section 11 by means of a fixing rod, so that the screen 8 can be fixed by means of the fixing rod and the screen 8 can be easily lifted by means of the fixing rod.

[0049] Of course, in practical applications, the screen 8 can be omitted. The aquaculture water in the aquaculture device can be drained and the device can be lifted out of the water for harvesting. However, this requires pumping, changing, and lifting the device, which is more complicated and consumes more manpower and resources.

[0050] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
