Description

Technical Field

[0001] The utility model relates to the technical field of high-density aquaculture, and more specifically, to a high-density aquaculture device. Background Art

[0002] High-density aquaculture mostly uses circular above-ground aquaculture ponds. The aquaculture density is 5-10 times that of ordinary aquaculture methods. The natural dissolved oxygen in the water cannot meet the breathing needs of aquatic products, and artificial oxygen supplementation is required. The metabolic products and feed residues of high-density aquaculture are also several times that of ordinary aquaculture methods. If they are not discharged in time after being deposited at the bottom of the pond, the oxidation reaction will further consume the dissolved oxygen in the water and release toxic substances, causing the water in the pond to deteriorate, causing aquatic products to be hypoxic and sick. The existing treatment plan is to install a submersible sewage pump in the aquaculture pond to pump the bottom sewage to the sedimentation tank for natural sedimentation, and then transport it back to the aquaculture pond through a waterfall filter.

[0003] The disadvantages of the existing treatment scheme are that the sedimentation tank occupies a large area, sedimentation takes a long time and the effect is not good, the filter element of the waterfall filter needs to be cleaned every day, and the maintenance workload is large; it causes great disturbance to the water body and can only achieve local oxygenation, and the oxygenation is uneven and the amount of oxygenation is limited.

[0004] In order to discharge the waste in the pool in time, recycle water resources and evenly replenish dissolved oxygen in the water of the pool, it is necessary to develop a new type of sewage discharge and circulating water and oxygen replenishment device. Utility Model Content

[0005] The utility model provides a high-density aquaculture device to solve the problems that the dirt in the existing high-density aquaculture pool cannot be discharged in time and it is difficult to solve the problem of water resource recycling.

[0006] According to one aspect of the utility model, a high-density aquaculture device is provided for installation in a culture pond, the high-density aquaculture device comprising a filter tank, a sewage pump, an oxygen and water supply pipe and a flushing pipe. The bottom of the culture pond is conical and is provided with a sewage outlet, the sewage outlet is connected to the filter tank through an external sewage pipe of the sewage pump; the flushing pipe is installed in a ring shape at the lower part of the culture pond, and the oxygen and water supply pipe is installed in a ring shape at the upper part of the culture pond. Control valves are provided on the oxygen and water supply pipe and the flushing pipe, and the oxygen and water supply pipe and the flushing pipe are connected to the upper part of the filter tank through a mother pipe.

[0007] Preferably, based on the above solution, a connecting pipe is provided between the flushing pipe and the main pipe, and the control valve is mounted on the connecting pipe.

[0029] See also Figure 1 , and combined with Figure 2 and Figure 3 As shown, a high-density aquaculture device of the utility model is used to be installed in a culture pond 1. The high-density aquaculture device includes a filter tank 31, a sewage pump 23, an oxygen and water supply pipe 43 and a flushing pipe 53. The bottom of the culture pond 1 is conical and is provided with a sewage outlet. The sewage outlet is connected to the filter tank 31 through a sewage pipe 24 externally connected to the sewage pump 23, and a sewage valve 22 is provided on the sewage pipe 24; the flushing pipe 53 is annularly installed at the lower part of the culture pond 1, and the oxygen and water supply pipe 43 is annularly arranged at the upper part of the culture pond 1. Control valves are provided on the oxygen and water supply pipe 43 and the flushing pipe 53, and the oxygen and water supply pipe 43 and the flushing pipe 53 are connected to the upper part of the filter tank 31 through the mother pipe 41.

[0030] When in use, by controlling the sewage valve 22 and the sewage pump 23 to be opened intermittently, the sewage deposited at the bottom of the culture pond 1 is pressurized and transported to the filter tank 31, and the filter tank 31 is preferably a vertical ceramic filter tank 31. The filter screen 21 is provided on the sewage outlet, which can not only prevent large particles of debris from entering the sewage pipe 24 and damaging the sewage pump 23, but also prevent local negative pressure from harming aquatic products. The sewage pump 23 is preferably a flat sewage pump 23, which can adjust the flow rate and pressure according to changes in factors such as climate, water body and aquatic product density to meet the breeding needs.

[0031] After the dirt is introduced from the bottom of the vertical ceramic filter tank 31, it is filtered through the material in the filter tank 31, and then output from the main pipe 41 at the top of the filter tank 31 and introduced into the oxygen and water supply tank. The residual dirt left by the filtration is discharged to the drainage ditch through the drainage pipe 24 at the bottom of the filter tank 31.

[0032] The oxygen supply and water supply pipe 43 is arranged in a ring shape at the upper part of the culture pond 1 to maintain a small pressure deviation at each spray port 60. Preferably, the oxygen supply and water supply pipe 43 includes a main pipe 44 and a plurality of coaxially spaced pipe bodies 45, the pipe bodies 45 are connected to the mother pipe 41 through the main pipe 44, and a plurality of spray ports 60 are spaced at intervals at the bottom of the water supply and oxygen supply pipe. The circulating water is injected into the culture pond 1 from the spray ports 60, and the water body can be evenly oxygenated while achieving the water supply function. It should be noted that the spray ports 60 of the utility model change the waterfall-type oxygen supply to a jet or trickle-type oxygen supply, which reduces the disturbance to the water body and can also increase the contact area between the water flow and the air to increase the dissolved oxygen content. For the specific structure, please refer to Figure 2 , Figure 4 and Figure 5 shown.

[0033] It should be noted that a connecting pipe 52 is provided between the flushing pipe 53 and the main pipe 41, the control valve is installed in the connecting pipe 52, the flushing pipe 53 is provided with a high-pressure nozzle 54, and the high-pressure nozzle 54 is arranged opposite to the bottom conical surface of the breeding pond 1. The specific structure is as follows: Figure 6 shown.

[0034] When the dirt at the bottom 70 of the culture pond cannot be drained naturally, the bottom of the culture pond 1 can be flushed with circulating water by forming a jet through the high-pressure nozzle 54 on the flushing pipe 53 to assist the dirt to be discharged from the drain outlet.

[0035] The utility model is a high-density aquaculture device. During normal operation, only sewage discharge and water and oxygen replenishment operations are intermittently performed. The sewage valve 22, sewage pump 23 and control valve 42 on the water and oxygen replenishment pipe are opened, and the control valve 51 on the flushing pipe 53 is closed. When flushing operations are required, the sewage valve 22, sewage pump 23 and control valve 51 on the flushing pipe 53 are opened, and the control valve 42 on the water and oxygen replenishment pipe is closed. When the device is stopped, the variable frequency sewage pump 23 and the valve are both in a closed state.

[0036] The utility model is a high-density aquaculture device, which changes the traditional round-bottomed aquaculture pond 1 into a conical structure, so as to collect metabolic products and feed residues and discharge them from the sewage outlet. At the same time, a sewage pump 23 is intermittently opened to pressurize and transport the sewage deposited at the bottom of the pond to the vertical ceramic filter tank 31, so as to realize the timely discharge of sewage in the pond and the recycling of water resources.

[0037] The utility model provides a high-density aquaculture device, which can filter sewage through a filter tank 31 and then introduce the sewage into a culture pond 1 through a water and oxygen supply pipe for secondary utilization.

[0038] Finally, the method of this application is only a preferred implementation scheme and is not intended to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
