Description

Technical Field

[0001] The utility model relates to the field of aquaculture, in particular to an aquaculture pond. Background Art

[0002] In industrial recirculating water shrimp farming systems, how to deal with shrimp shells, dead shrimp, leftover bait, feces and other pollutants in the aquaculture water while preventing live shrimp from escaping is a key technology, which is also the key to determining the success of recirculating water shrimp farming and other crustacean aquatic animals. Existing recirculating water shrimp farming systems, such as the Chinese utility model patent with application number CN202122921936.6, are named a device for separating and collecting dead shrimp shells and automatic sewage discharge from aquaculture ponds. There are some problems with the current recirculating water shrimp farming system:

[0003] First, the waste collection devices in the circulating water shrimp farming systems on the market are mostly integrated designs. The holes for removing shrimp shells, residual bait, and feces are small and easy to get clogged. After the blockage, the water flow cannot be circulated and filtered normally, resulting in a decline in water quality and large-scale death of shrimp. In addition, the circulating water farming cycle is short and needs to be cleaned after a cycle. The integrated device is not easy to disassemble and clean, and it is easy to leave residual bait and feces, resulting in the secondary farming water quality still not meeting the standards.

[0004] Secondly, the current way of discharging shrimp shells on the market is mainly forced discharge, such as the Chinese utility model patent with publication number CN218418004U. The forced discharge method is to remove shrimp shells in the shrimp pond by bottom forced discharge. This device is installed at the bottom discharge of the shrimp pond. It is equipped with a movable pull rod for controlling the bottom discharge switch on the basis of the ordinary bottom discharge, and an isolation cover is also installed on the pull rod. The specific use of the forced discharge shrimp shell discharger is: under normal use, the isolation cover is in an upward opening state, at which time dead shrimps, shrimp shells, feces and other dirt will be collected at the bottom discharge port, but at this time the bottom discharge controlled by the movable pull rod is in a closed state, so although the dirt will be collected at the bottom discharge, it will not be discharged. When discharging shrimp shells and other dirt, first drop the isolation cover. Due to the drop of the isolation cover, the dirt in the bottom discharge and the live shrimp in the shrimp pond are in a state of isolation. In this state, open the bottom discharge to prevent the live shrimp from being sucked into the bottom discharge port. Open the movable pull rod to open the bottom discharge and suck all kinds of dirt from the bottom discharge. After all the dirt is discharged, put the movable pull rod back to its original position, close the bottom discharge port, and then open the isolation cover. At this time, the dirt will continue to gather at the bottom discharge but will not be discharged. The forced discharge shrimp shell discharger has low reliability in use and is prone to damage to live shrimps, resulting in economic losses. Utility Model Content

[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] The utility model provides an aquaculture pond, which is used in the field of sewage discharge and circulating water treatment in aquaculture ponds for fish, shrimp and the like.

[0030] Please refer to Figures 1 to 3As shown, an aquaculture pond of the utility model comprises a pond body 1, a side wall of the pond body 1 is provided with a shrimp shell collecting frame 2, the shrimp shell collecting frame 2 extends to the bottom of the pond through a shrimp shell conveying pipe 3, and the shrimp shell conveying pipe 3 is connected to an air conveying pipe 4.

[0031] From the above description, it can be seen that the beneficial effects of the utility model are: an aquaculture pond, when in use, the shrimp shell collection frame 2 is installed on the side wall of the pond body 1, which cannot be completely submerged in water, and the water level position is preferably at the shrimp live escape port. Completely submerged in water may cause the shrimp shells to float out due to aeration, and live shrimps may also swim in, which poses a hidden danger. Then, air is introduced into the shrimp shell delivery pipe 3 by using the air delivery pipe 4, and the shrimp shells are transported from the shrimp shell delivery pipe 3 to one end of the pond bottom by air lift to the shrimp shell collection frame 2 to complete the collection. When the air lift effect is insufficient, only the aeration pipe in the pond body 1 needs to be closed to improve the air lift effect. The utility model uses an efficient air lift system to efficiently separate the shrimp shells from the pond bottom by air lift, improve the shrimp shell collection effect, ensure that the bottom sewage outlet of the pond is not blocked by shrimp shells, reduce the burden of bottom sewage discharge, and enhance the function of the aquaculture system.

[0032] In an optional embodiment, the shrimp shell collecting frame 2 is provided with a shrimp shell inlet 21 connected to the shrimp shell conveying pipe 3 , and an annular enclosure 22 is provided at the shrimp shell inlet 21 .

[0033] As can be seen from the above description, the annular enclosure 22 is arranged around the shrimp shell inlet 21 to prevent the shrimp shells collected in the shrimp shell collection frame 2 from falling from the shrimp shell inlet 21 again to cause blockage, thereby ensuring the air lift collection effect.

[0034] In an optional embodiment, the shrimp shell collecting frame 2 includes a frame body and a mesh cover 23, the mesh cover 23 is covered on the frame body, and the shrimp shell conveying pipe 3 is connected to the frame body.

[0035] From the above description, it can be seen that the frame plays a supporting and installing role, and the role of the net cover 23 is to prevent live shrimps from entering the shrimp shell collection frame 2 from the outside, and to prevent the shrimp shells in the shrimp shell collection frame 2 from falling out of the shrimp shell collection frame 2.

[0036] In an optional embodiment, the side wall of the frame has a reflux port, and the upper edge of the frame has a live shrimp escape port 24.

[0037] From the above description, it can be seen that the function of the reflux port is to allow the pool water entering the frame to flow back into the pool body 1, and the live shrimp escape port 24 located at the upper edge is used to allow the live shrimp that mistakenly enter the frame to swim back to the pool body 1.

[0038] In an optional embodiment, a shrimp shell discharge cage 5 is provided at the bottom of the pond, and the shrimp shell discharge cage 5 is provided with a bottom discharge port 51. The shrimp shell collection frame 2 is connected to the shrimp shell discharge cage 5 through a shrimp shell conveying pipe 3, and the shrimp shell conveying pipe 3 is connected to the air pipe 4 through the shrimp shell discharge cage 5.

[0039] From the above description, it can be seen that the function of the shrimp shell discharge cage 5 is to collect the shrimp shells at the bottom of the pool and then discharge them from the bottom discharge port 51. Air is introduced into the shrimp shell discharge cage 5 through the air pipe 4, and the gas pressure is used to generate buoyancy to transport the pool water and shrimp shells entering the bottom discharge port 51 to the shrimp shell collection frame 2.

[0040] In an optional embodiment, the shrimp shell discharge cage 5 includes a discharge pipe 52 and a live shrimp escape prevention pipe 53, the bottom discharge port 51 is arranged on the side wall of the discharge pipe 52, the live shrimp escape prevention pipe 53 is arranged in the inner cavity of the discharge pipe 52, the live shrimp escape prevention pipe 53 is connected to the bottom drainage valve 11 of the pond body 1, and the discharge pipe 52 is respectively connected to the shrimp shell conveying pipe 3 and the air conveying pipe 4.

[0041] From the above description, it can be seen that the bottom of the breeding pond body 1 is designed to be a cone bottom, and a bottom drainage outlet is provided at the center of the bottom of the breeding pond. During normal breeding, water is discharged from the bottom drainage outlet and the surface water outlet at the same time. After a long time, the shrimp shells or feces that sink to the bottom will gradually move to the bottom water outlet in the center of the breeding pond and accumulate. Therefore, a live shrimp escape prevention pipe 53 structure is designed. The upper end of the live shrimp escape prevention pipe 53 is blocked, and the lower end is connected to the bottom water outlet of the breeding pond. The side wall has a grid permeable structure. The grid blocks the live shrimp and larger sediments such as shrimp shells from being flushed out from the bottom drainage pipe. Only water and small dirt such as feces can pass through and flush out from the bottom drainage outlet. After the aeration is turned on, the shrimp shells that are blocked and stored outside are sucked into the collection frame by air lift.

[0042] In an optional embodiment, the shrimp shell collecting frame 2 further includes a mounting basket 6 , the mounting basket 6 is provided with a hook 61 connected to the pool body 1 , and the shrimp shell collecting frame 2 is arranged in the mounting basket 6 .

[0043] From the above description, it can be seen that the mounting basket 6 is a basket-type structure that can take in and out water. The mounting basket 6 can be hung on the inner wall of the pool body 1 through a hook 61, and the shrimp shell collection frame 2 is stored in the mounting basket 6 and submerged in the pool water.

[0044] In an optional embodiment, the side wall of the pool body 1 is provided with a surface water overflow frame 7, and the surface water overflow frame 7 has a surface water overflow hole. The surface water overflow frame 7 extends to the outside of the pool body 1 through an overflow pipe, and the surface water overflow frame 7 is provided with an outlet pipe 71 for connecting the overflow pipe and cooperating with the socket 62.

[0045] It can be seen from the above description that by installing the surface water overflow frame 7, surface water discharge can be achieved while taking shrimp shells.

[0046] In an optional embodiment, the surface water overflow frame 7 is arranged in the mounting basket 6.

[0047] It can be seen from the above description that the shrimp shell collecting frame 2 and the surface water overflow frame 7 are uniformly installed in the installation basket 6, which is convenient for installation and management.

[0048] In an optional embodiment, the other end of the gas delivery pipe 4 extends to the outside of the pool body 1 , and the other end of the gas delivery pipe 4 is provided with a gas delivery valve 41 .

[0049] It can be seen from the above description that the gas effect can be controlled by adjusting the gas delivery valve 41.

The bottom discharge port 51 is arranged on the side wall of the discharge pipe 52, and the live shrimp escape prevention pipe 53 is arranged in the inner cavity of the discharge pipe 52. The live shrimp escape prevention pipe 53 is connected to the bottom drainage valve 11 of the pond body 1, and the discharge pipe 52 is connected to the shrimp shell delivery pipe 3 and the air delivery pipe 4 respectively. The discharge pipe 52 is a straight pipe, and the distance between the inner wall of the discharge pipe 52 and the outer wall of the live shrimp escape prevention pipe 53 ranges from 20 mm to 80 mm. The distance between the discharge pipe 52 and the live shrimp escape prevention pipe 53 determines the amount of shrimp shells passing through. The discharge pipe 52 and the live shrimp escape prevention pipe 53 are both provided with through holes. The through holes on the discharge pipe 52 are for shrimp shells to enter, and the through holes on the live shrimp escape prevention pipe 53 prevent live shrimps from escaping to the bottom sewage outlet. The shrimp shell discharge cage 5 also includes a core plug 54, a fixing ring 55 and a fixing pipe 56. The top of the discharge pipe 52 has an installation opening, and a large and small head straight pipe fitting 58 with large and small heads is provided at the installation opening. The large and small head straight pipe fitting 58 also plays a role in preventing live shrimps from entering. The small end of the large and small head straight pipe fitting 58 is fixed to the shrimp shell delivery pipe 3 through the core plug 54, the fixing ring 55 and the fixing pipe 56. The pipes can be disassembled and cleaned respectively for secondary recycling. The discharge pipe 52 is connected to the gas transmission pipe 4 through a pagoda joint 57.

[0053] The shrimp shell collection frame 2 also includes a mounting basket 6, which is provided with a hook 61 connected to the pool body 1, and the shrimp shell collection frame 2 is arranged in the mounting basket 6. The hook 61 is arranged on the basket body of the mounting basket 6 by welding. The side wall of the pool body 1 is provided with a surface water overflow frame 7, which has a surface water overflow hole, and the surface water overflow frame 7 extends to the outside of the pool body 1 through an overflow pipe. The bottom of the mounting basket 6 is provided with two sockets 62, and the frame body is provided with an inlet pipe for connecting the shrimp shell delivery pipe 3 and plugging with the sockets 62. The surface water overflow frame 7 is arranged in the mounting basket 6, and the surface water overflow frame 7 is provided with an outlet pipe 71 for connecting the overflow pipe and plugging with the socket 62. The inlet pipe and the outlet pipe 71 are both short pipes and are installed by welding. The other end of the gas delivery pipe 4 extends to the outside of the pool body 1, and the other end of the gas delivery pipe 4 is provided with a gas delivery valve 41.

[0054] The working principle of this embodiment is:

[0055] The assembly method before use is as follows: first, the shrimp shell collection frame 2 and the surface water overflow frame 7 are respectively inserted into the corresponding sockets of the installation basket 6, and then the installation basket 6 is fixed on the fish pond through the hook 61. Then, the live shrimp escape prevention pipe 53 is inserted into the discharge pipe 52 of the shrimp shell discharge cage 5, and then the size head straight pipe fitting 58, the core 54 and the fixing pipe 56 are inserted, and then the shrimp shell discharge cage 5 is installed at a preset position on the bottom of the pond. Finally, a shrimp shell delivery pipe 3 is connected between the shrimp shell collection frame 2 and the shrimp shell discharge cage 5, and after being fixed with a fixing ring 55 such as a clamp, it is connected to the gas delivery pipe 4 through the pagoda head, and the device is installed.

[0056] The specific use principle of the shrimp shell collecting device is as follows: open the gas delivery valve 41, firstly, the shrimp shells gathered around the shrimp shell discharge cage 5 are pushed into the shrimp shell collecting cage together with the water flow by air push, and then when the water and shrimp shells are collected in the shrimp shell collecting frame 2 at the same time, the water flow will be filtered back into the shrimp pond through the surrounding net cover 23, and finally only the shrimp shells are left in the shrimp shell collecting frame 2. As the number of shrimp shells gathered in the shrimp shell collecting frame 2 increases to a certain extent, the user can continue to use it by pulling out the shrimp shell collecting frame 2 from the installation basket 6 and pouring out the shrimp shells therein. The live shrimps accidentally sucked into the shrimp shell collecting frame 2 can return to the pond body 1 through the live shrimp escape port 24, and at the same time, because of the effect of the water flow backflow, the live shrimps in the pond body 1 cannot swim into the shrimp shell collecting frame 2 from the escape port. The opening on the surface of the surface water overflow frame 7 next to the shrimp shell collecting frame 2 is relatively small, which can prevent the live shrimps from swimming into the surface water overflow frame 7 while ensuring the surface water overflow.

[0057] Since the shrimp farming cycle is short, each device needs to be cleaned after a cycle. Therefore, the components are installed with detachable connection structures such as sockets, which can facilitate subsequent cleaning and protection.

[0058] In summary, the aquaculture pond of the utility model is particularly suitable for solving the problem of shrimp shell collection in shrimp ponds. It has a reasonable structure and adopts a multiple cavity partition design. Different cavity partitions have different apertures and different functions, such as blocking live shrimps, allowing mistakenly collected live shrimps to escape, returning pool water, or discharging surface water. The core of this device is to use an efficient air lift system to efficiently separate shrimp shells from the bottom of the pool, improve the shrimp shell collection effect, ensure that the sewage outlet at the bottom of the pool is not blocked by shrimp shells, reduce the burden of bottom sewage discharge, and enhance the function of the aquaculture system. At the same time, the upper part of the system not only has the function of collecting shrimp shells and blocking live shrimps, but also has the function of surface water overflow. This device can be designed in a variety of models and specifications according to actual needs to suit pools of different sizes and types. It has strong applicability, low failure rate, and high shrimp shell separation efficiency.
