Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a breeding device and a breeding system. Background Art

[0002] Aquatic products such as fish, shrimp and crab are generally cultured in aquaculture devices. The upper part of the aquaculture device uses aquaculture water to culture the aquatic products. The excrement of the aquatic products and feces such as leftover bait will be deposited and gathered in the lower part of the aquaculture device to achieve separation of feces and sewage, which is convenient for discharge and subsequent treatment.

[0003] At present, in order to facilitate the deposition of excrement and sewage, the lower part of the breeding device is generally set as a cone bucket structure. For example, the prior art CN217184440U discloses a circulating water high-density fish farming system, which is conducive to the deposition and accumulation of excrement and residual bait by setting an arc-shaped pool bottom. However, the angle between the tangent of the cross-sectional arc of the pool bottom and the horizontal line is 15-25°, the slope is small, and the speed of excrement deposition is slow, resulting in low excrement separation efficiency. On the contrary, if the cone bucket structure at the bottom of the breeding device is set to a larger slope than the horizontal plane, although the rapid deposition of excrement and sewage can be achieved to improve the efficiency of excrement separation, the overall height of the breeding device will be significantly increased, resulting in limited applicable environment and installation.

[0027] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figure 1 The present invention provides a breeding device, including a device body 1, the upper part of the device body 1 is a straight cylinder section 11 for breeding aquatic products, the lower part of the device body 1 is a conical cylinder section 12 for feces sedimentation and separation, the straight cylinder section 11 and the conical cylinder section 12 are connected, and the conical cylinder section 12 includes at least two conical buckets 121, and the at least two conical buckets 121 are flatly arranged to form the conical cylinder section 12.

[0031] The straight section 11 and the conical section 12 are arranged up and down and connected to form an integral structure. The upper part of the breeding device is the straight section 11, which is used for breeding aquatic products. The straight section 11 has a large internal space, which is conducive to high-density breeding of aquatic products, thereby increasing the breeding cost.

[0032] Aquatic excrement and leftover bait and other feces will settle downward, and the speed of feces deposition directly affects the feces separation efficiency. The lower part of the breeding device is a cone section 12, which is divided into at least two cone buckets 121. Compared with a whole large cone bucket, at least two cone buckets 121 can have a larger slope compared to the horizontal plane to accelerate the downward deposition of aquatic excrement and leftover bait and other feces, thereby improving the feces separation efficiency, and can control the height of the cone section 12, thereby controlling the height of the breeding device, so that the breeding device can be used in both shallow waters and deep waters, avoiding installation restrictions on the breeding device, so that the breeding system applicable to the breeding device is less restricted, and the applicable environment of the breeding system is less restricted, and aquaculture can be realized in any waters such as rivers, lakes or fish ponds.

[0033] In addition, the movement of aquatic products in the straight section 11 will disturb the water body, which is not conducive to the deposition of feces and sewage. The conical section 12 of the present invention is divided into at least two cone buckets 121 to form a stable flow area, thereby reducing the disturbance of aquatic products to the water body and improving the feces and sewage separation effect.

[0034] Of course, under the premise of combining actual working conditions, the more cone buckets there are, the more conducive it is to improving the flow stabilization effect, and controlling the height of the breeding device while maintaining a large slope to ensure the manure separation effect and expand the scope of application.

[0035] The cross section of the straight section 11 is circular, elliptical or polygonal, and the cross section of the top of the conical section 12 is adapted to the cross section of the straight section 11. The straight section 11 can be cylindrical ( Figure 1 and Figure 6 ), elliptical column, triangular prism, quadrangular prism ( Figure 7 ), pentagonal prism, hexagonal prism or other straight cylindrical structures to ensure that the straight cylindrical section 11 has a larger internal space to facilitate high-density aquaculture.

[0036] The conical cylinder section 12 can be arranged directly below the straight cylinder section 11 as a whole. Figure 1 and Figure 6As shown, the shape and size of the top cross section of the conical cylinder section 12 are adapted to the cross section of the straight cylinder section 11. Alternatively, the conical cylinder section 12 is arranged below a portion of the straight cylinder section 11, such as Figure 7 As shown, the shape and size of the cross section of the left area of ​​the straight section 11 are adapted to the shape and size of the cross section of the top of the conical section 12. In short, as long as the straight section 11 and the conical section 12 can be connected and the space of the conical section 12 is sufficient to deposit feces and sewage, the size is not particularly limited.

[0037] For the cone section 12, the cone bucket 121 includes at least one side wall, at least one side wall is connected end to end to form the bucket wall of the cone bucket 121, the side wall is an inclined arc-shaped side wall or a plate-shaped side wall, and the area enclosed by the bottom end of at least one side wall in the same cone bucket 121 is smaller than the area enclosed by the top end. The cone bucket 121 can be of any shape, for example, a cone formed by at least one arc-shaped side wall, or an irregular shape formed by at least one arc-shaped side wall and at least one plate-shaped side wall, or a pyramid shape formed by at least three plate-shaped side walls, etc. Figure 4 In the first embodiment shown, the cone bucket 121 has three side walls of an arc-shaped structure, and a plurality of cone buckets 121 are arranged flat to form a petal-shaped cone cylinder section 12. Alternatively, as Figure 6 In the second embodiment shown, the cone bucket 121 has six side walls of an arc-shaped structure, and a plurality of cone buckets 121 are arranged flat to form a honeycomb cone section 12. Alternatively, Figure 7 In the third embodiment shown, the cone bucket 121 has four side walls of a plate structure, and a plurality of cone buckets 121 are arranged flat to form a grid-structured cone cylinder section 12. Of course, in practical applications, the cone cylinder section 12 can also be designed as a grid structure, a diamond structure, etc., and the shape can be selected arbitrarily, as long as a large slope, a controlled height, and a large number of cone buckets 121 can be maintained, so that feces and sewage can be separated efficiently.

[0038] It should be noted that although aquatic products generally swim in the straight section 11, a very small number of aquatic products may swim into the conical section 12, or even swim to the bottom of the conical section 12, causing the aquatic products to be deposited along with the feces and sewage or even separated from the aquaculture device. Figure 4 , Figure 5 and Figure 7 As shown, a baffle plate 122 is provided at the inner bottom of the cone bucket 121 , the peripheral edge of the baffle plate 122 is connected to the bucket wall of the cone bucket 121 , and the baffle plate 122 is provided with a plurality of through holes 1221 .

[0039] The shape of the baffle 122 is adapted to the wall of the cone bucket 121 to ensure the sealed connection between the baffle 122 and the wall of the cone bucket 121. The setting of the baffle 122 can prevent the aquatic products from swimming to the bottom of the cone cylinder section 12, thereby ensuring that the aquatic products are always cultured in the culture device, and the excrement is deposited to the bottom of the cone cylinder section 12 through the plurality of through holes 1221 on the baffle 122, so as to achieve effective separation of excrement.

[0040] See also Figure 1 and Figure 2 The bottom of the cone bucket 121 is provided with a flushing port, which is located below the baffle 122 and is connected to a flushing pipe 2. The feces and sewage deposited for a long time may block the through holes 1221, thereby affecting the feces and sewage separation effect. The flushing pipe 2 can lead water into the cone bucket 121 through the flushing port, thereby flushing the baffle 122 to ensure that the through holes 1221 are unblocked.

[0041] After the manure is deposited and separated at the bottom of each cone bucket 121, it is discharged from the breeding device for subsequent treatment. Specifically, the bottom of the cone bucket 121 is connected to a sewage pipe 3, which is located below the baffle 122. The sewage pipes 3 of at least two cone buckets 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 sewage chamber 5 and the sewage chamber 5 is connected to the manure treatment equipment through a main pipe 4. There is a liquid level difference between the cone bucket 121 and the manure treatment equipment or a power device is provided.

[0042] Taking the manure treatment equipment as a transfer tank as an example, in the simplest way, the sewage pipes 3 of each cone bucket 121 are directly connected to the transfer tank. Although this structure reduces the setting of other components, the pipeline structure is complicated. Preferably, the sewage pipes 3 of each cone bucket 121 are connected to the main pipe 4 to connect to the transfer tank through the main pipe 4, and the pipeline structure is simplified. However, in order to accommodate the manure in all cone buckets 121, the diameter of the main pipe 4 needs to be large enough, which has high requirements on the size of the main pipe 4 and is inconvenient to select.

[0043] More preferably, if Figure 2 , Figure 6 and Figure 7 As shown, the sewage pipes 3 of each cone bucket 121 are connected to the sewage chamber 5, and the sewage chamber 5 is connected to the transfer tank through the main pipe 4. The main pipe 4 is set at a certain distance from the bottom of the sewage chamber. In this way, after the feces and sewage of each cone bucket 121 are discharged into the sewage chamber 5, the feces and sewage need to accumulate at the position where the main pipe 4 is located before they can be discharged to the transfer tank, which reduces the burden of the main pipe 4 and simplifies the pipeline.

[0044] The discharge of feces from the cone bucket 121 to the feces treatment equipment can be achieved by utilizing the liquid level difference, thereby achieving unpowered sewage discharge and reducing energy consumption. Alternatively, feces can be pumped out by a power pump and discharged into the feces treatment equipment. Alternatively, Figure 7As shown, the feces and sewage are discharged by air lift, and the sewage pipe 3 is connected to the air inlet pipe 9, and gas is output into the sewage pipe 3 through the air inlet pipe 9, so that the feces and sewage are discharged into the sewage chamber 5 by air lift, and the feces and sewage are discharged to the feces and sewage treatment equipment through the main pipe 4, and the air lift is discharged through the air lift outlet at the top of the sewage chamber 5. Whether it is a power pump or an air lift method for sewage discharge, it is beneficial to improve the efficiency of feces and sewage discharge and prevent feces and sewage from accumulating in the cone bucket 121 or the sewage chamber 5.

[0045] In addition, see Figure 1 and Figure 4 The aquaculture device is provided with an oxygenation component, which includes an oxygenation device, an oxygen supply pipe 6 and an oxygen delivery pipe 7. The oxygen delivery pipe 7 is connected to the oxygenation device through the oxygen supply pipe 6. The oxygen delivery pipe 7 is arranged at the bottom of the straight tube section 11, and a plurality of oxygen delivery holes are opened on the oxygen delivery pipe 7. The oxygenation device of the aquaculture component provides oxygen to be supplied to the oxygen delivery pipe 7 through the oxygen supply pipe 6, so that the oxygen delivery holes of the oxygen delivery pipe 7 are used to increase oxygen into the straight tube section 11, so as to realize aeration and oxygenation in the aquaculture device, so as to ensure the dissolved oxygen content of the aquaculture water body, which is beneficial to the growth of aquatic products.

[0046] The oxygen supply pipe 6 is an annular structure and is arranged at the top of the straight section 11. At least two oxygen delivery pipes 7 are provided and are connected to the oxygen supply pipe 6. The density of the oxygen delivery holes on the oxygen delivery pipe 7 gradually increases from the bottom edge of the straight section 11 to the bottom center. The oxygen supply pipe 6 is arranged as an annular structure to achieve uniform oxygen supply to the oxygen delivery pipe 7. The oxygen delivery holes of the oxygen delivery pipe 7 are denser at the center, which can not only make the dissolved oxygen distribution more uniform through aeration, but also facilitate the separation of feces and sewage deposition, and the lighter floating objects are pushed to the peripheral edge of the aquaculture water body. In this way, a water outlet is arranged on the peripheral side of the aquaculture device, and the floating objects can be discharged from the water outlet to ensure the water quality of the aquaculture water body. In addition, a large amount of aeration in the center can increase the water level of the aquaculture water body, so that the water surface is higher than the water outlet, so that water can flow out from the water outlet to the purification unit without power, which is conducive to reducing energy consumption.

[0047] In addition, see Figure 3 A movable screen 8 is provided between the straight section 11 and the conical section 12. The screen 8 is laid flat on 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 the feces and sewage can be smoothly deposited. During the aquaculture process, the screen 8 is fixed above the oxygen supply pipe 7. When it is necessary to catch aquatic products, the screen 8 can be lifted and moved upward to gradually reduce the aquaculture space where the aquatic products are located, thereby driving the aquatic products to the upper part of the straight section 11 for easy catching.

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

[0049] Of course, in actual applications, the screen 8 may not be provided, and the aquaculture water in the aquaculture device can be directly drained and then the aquaculture device can be lifted from the water area for fishing. However, it requires actions such as pumping water, changing water, and lifting, which is more cumbersome and consumes manpower and material resources.

[0050] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
