Description

Technical Field

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

[0002] The land-based circular pond recirculating aquaculture system is an innovative green and ecological aquaculture method. It achieves high-density, intensive fish farming by constructing circular aquaculture ponds on the ground and equipping them with a wastewater treatment and recycling system. This system utilizes a wastewater collection and discharge device at the bottom of the circular pond to guide the wastewater into an artificial wetland for treatment. The purified wastewater is then returned to the circular pond for reuse, thus achieving the goal of ecological aquaculture.

[0003] Currently, application document CN112806308A discloses an aquaculture pond, including a pond body, a drain pipe, an overflow pipe, a partition net, and an aeration pipe. The upper part of the pond body is rectangular, and the lower part is funnel-shaped. The drain pipe is fixed at the center of the bottom of the pond body and is equipped with a ball valve. The partition net is located above the drain pipe, and its edge is connected to the inner wall of the pond body. The aeration pipe is fixed on the inner walls of two adjacent sides of the pond body. The overflow pipe is fixed at the apex where the inner walls of the two sides of the pond body without the aeration pipe intersect. Air is injected through the aeration pipe, which propels the excrement in the pond body along the bottom of the pond, causing the excrement to collect in the drain pipe and then be discharged through the drain pipe.

[0004] However, when air is injected into the aeration pipes located around the pool, it causes the excrement inside the pool to float in the water. The excrement cannot be pushed by the air to collect in the drain pipe, resulting in the excrement not being discharged in time. Utility Model Content

[0005] To facilitate the timely removal of excrement from the pond, this application provides an aquaculture device.

[0006] The aquaculture device provided in this application adopts the following technical solution:

[0007] An aquaculture device includes a pond body with a sludge collection channel at the bottom of the pond body located in the middle of the pond body. A sludge discharge pipe is provided at the bottom of the pond body and is connected to the sludge collection channel. An aeration device is provided above the sludge collection channel. The aeration device is used to inject air to form bubble cavities in the water body. Under the action of the bubble cavities, the excrement in the pond body is adsorbed and moves towards the middle of the pond body and enters the sludge collection channel.

[0008] Optionally, the aeration device includes an aeration pipe and an air pump. The air pump is located outside the tank body, one end of the aeration pipe is connected to the output end of the air pump, and the other end of the aeration pipe is located in the middle of the tank body and above the sludge collection channel.

[0009] Optionally, the aeration device further includes an aeration disc, which is located above the sludge collection channel and connected to the aeration pipe.

[0010] Optionally, the aeration pipe is fixedly installed in the middle on the side wall and bottom wall of the pool.

[0011] Optionally, a filter screen is installed inside the pool and covering the sludge collection channel, and the aeration disc is fixedly installed on the filter screen, so that the excrement falls into the sludge collection channel after passing through the filter screen.

[0012] Optionally, the pool body is provided with a circulating water return pipe, and the outlet end of the circulating water return pipe is immersed below the liquid surface.

[0013] Optionally, the pool body is provided with a circulating water return pipe, and the outlet end of the circulating water return pipe is immersed below the liquid surface.

[0014] Optionally, the part of the water outlet pipe that is immersed in the pool body is provided with multiple water inlet holes, which are evenly distributed along the length of the water outlet pipe.

[0015] Optionally, an overflow pipe is provided inside the pool, with the inlet port of the overflow pipe located near the top of the pool.

[0016] Optionally, a support rod is provided inside the pool and across the sludge collection channel, and the filter screen is located above the support rod and supported on the support rod.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. When excrement is discharged from the pool, the aeration device acts on the middle of the pool to generate a large number of bubbles at the bottom of the pool. Under the action of the bubbles, the excrement at the bottom of the pool is sucked up, causing the excrement to flow along the bottom of the pool and enter the sludge collection channel. It then enters the sewage pipe through the sludge collection channel and is then removed by the sewage pump, thus discharging the excrement from the pool in a timely manner.

[0019] 2. Because the aeration device is located in the middle of the pool, the bubbles generated by the aeration device absorb the flow of excrement. Compared with the flow of air that propels the excrement, this reduces the possibility of the excrement floating from the bottom of the pool to the surface, thereby improving the water quality of the pool.

[0024] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0025] This application discloses an aquaculture device. (Refer to...) Figure 1 The aquaculture device includes a pond body 1, a sludge collection channel 2 at the bottom of the pond body 1, the sludge collection channel 2 being located in the middle of the pond body 1, a sludge discharge pipe 3 at the bottom of the pond body 1, the sludge discharge pipe 3 being connected to the sludge collection channel 2, and a sludge discharge pump 4 installed on the sludge discharge pipe 3, the sludge discharge pump 4 being used to discharge the excrement in the sludge collection channel 3, and an aeration device 5 installed above the sludge collection channel 2, the aeration device 5 being used to inject air to form bubble cavities in the water, under the action of the bubble cavities, the excrement in the pond body 1 being adsorbed and moving towards the middle of the pond body 1 and entering the sludge collection channel 2.

[0026] When the excrement in the tank 1 is discharged, the aeration device 5 acts on the middle of the tank 1, generating a large number of bubbles at the bottom of the tank 1. Under the action of the bubbles, the excrement at the bottom of the tank 1 is sucked up, causing the excrement to flow along the bottom of the tank 1 and enter the sludge collection channel 2. Then, it enters the sewage pipe 3 through the sludge collection channel 2, and is then removed by the sewage pump 4, thus discharging the excrement from the tank 1 in a timely manner.

[0027] Reference Figure 1 In this embodiment, the aeration device 5 includes an aeration pipe 51 and an air pump 52. The air pump 52 is located outside the tank body 1. One end of the aeration pipe 51 is connected to the output end of the air pump 52, and the other end of the aeration pipe 51 is located in the middle of the tank body 1 and above the sludge collection channel 2. When aerating, the air pump 52 is started, and the air pump 52 injects air into the tank body 1 through the aeration pipe 51, thereby generating a large number of bubbles in the middle of the tank body 1. The operation is simple and convenient.

[0028] Reference Figure 1 Furthermore, the aeration device 5 also includes an aeration disc 53, which is located above the sludge collection channel 2 and connected to the aeration pipe 51. Air is introduced through the aeration pipe 51 and injected into the tank 1 through the aeration disc 53, improving the air distribution effect and making the air distribution more uniform. The aeration disc 53 also has good anti-clogging performance and good backflow prevention performance. Moreover, when the water quality in the tank 1 is complex or the operation is intermittent, the surface of the aeration disc 53 is not prone to sludge accumulation, which facilitates the aeration operation in the tank 1.

[0029] Reference Figure 1 To facilitate the installation of the aeration pipe 51 inside the tank body 1, the middle part of the aeration pipe 51 is fixedly installed on the side wall and bottom wall of the tank body 1.

[0030] Reference Figure 1 In this embodiment, a filter screen 6 is installed inside the pool body 1 and covering the sludge collection channel 2. An aeration disc 53 is fixedly installed on the filter screen 6. Excrement falls into the sludge collection channel 2 after passing through the filter screen 6. The filter screen 6 facilitates the installation of the aeration disc 53 and reduces the possibility of excrement entering the sludge collection channel 2 and re-entering the pool body 1 through the filter screen 6, thereby improving the sludge discharge efficiency of the pool body 1. Furthermore, a support rod 7 is installed inside the pool body 1 and spans the sludge collection channel 2. The filter screen 6 is located above the support rod 7 and supported on it. The support rod 7 supports the filter screen 6, reducing the possibility of deformation and preventing excrement from re-entering the pool body 1.

[0031] Reference Figure 1 In this embodiment of the application, in order to realize water circulation in the pool 1 and improve the water quality of the pool 1, a circulating water return pipe 8 is provided on the pool 1, and the outlet end of the circulating water return pipe 8 is immersed below the liquid surface; under the action of the circulating water return pipe 8, it is convenient to inject clean water into the pool 1, thereby improving the water quality; furthermore, a water outlet pipe 9 and a water pump 10 are provided on the pool 1, the water outlet pipe 9 extends into the lower part of the pool 1 and is immersed below the liquid surface, and the water outlet pipe 9 is connected to the water pump 10 for discharging water in the pool 1; when the water pump 10 is started, the water pump 10 draws water from the pool 1 and discharges it through the water outlet pipe 9, and during the water discharge process, some excrement is discharged from the pool 1.

[0032] Reference Figure 1 To improve the sewage discharge effect of the outlet pipe 9, multiple water inlet holes 11 are provided in the part of the outlet pipe 9 that is immersed in the pool body 1. The water inlet holes 11 are evenly distributed along the length of the outlet pipe 9. The multiple water inlet holes 11 increase the channels for the removal of excrement, thereby improving the discharge effect of excrement.

[0033] Reference Figure 1 To reduce the possibility of water overflowing the pool body 1, an overflow pipe is installed inside the pool body 1, with the inlet of the overflow pipe near the top of the pool body 1. When the water overflows the overflow pipe, it circulates through the overflow pipe, thus reducing the possibility of water overflowing the pool body 1.

[0034] The implementation principle of a breeding device according to an embodiment of this application is as follows:

[0035] When excrement is discharged from the pool 1, the air pump 52, aeration pipe 51 and aeration disc 53 act on the middle part of the pool 1 to generate a large number of bubbles at the bottom of the pool 1. Under the action of the bubbles, the excrement at the bottom of the pool 1 is sucked up, and the excrement flows along the bottom of the pool 1 into the sludge collection channel 2. It then enters the sewage pipe 3 through the sludge collection channel 2 and is then removed by the sewage pump 4, thus timely discharging the excrement from the pool 1.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
