The aquatic product recirculating aquaculture system can remove harmful pollutants such as residual bait, excrement, ammonia nitrogen, nitrite nitrogen and the like in aquaculture water and purify aquaculture environment. Therefore, the recirculating aquaculture system can solve the problem of low water resource utilization rate, provide a stable, reliable, comfortable and high-quality living environment for aquaculture organisms and provide favorable conditions for high-density aquaculture.
In order to remove large-particle dirt such as residual bait, excrement and the like in a culture water body in an earth pond, the current method is realized by a cyclone separator.

Detailed Description
The utility model is further described below with reference to examples, but not to be construed as being limited thereto, and any number of modifications which can be made by anyone within the scope of the claims are also within the scope of the claims.
Referring to fig. 1-2, the silt separation device for pond circulating water fish culture comprises a separation cylinder body 1. One side of the separation barrel body 1 is provided with a water inlet 2, and the water inlet 2 is connected with a sewage outlet pipeline of the cyclone separator so as to discharge culture wastewater with a large amount of silt in the cyclone separator into the separation barrel body 1. And a silt discharge port 3 is arranged on the separation barrel body 1 below the water inlet 2 and used for discharging silt precipitated in the separation barrel body 1. Specifically, the bottom surface of the separation cylinder 1 is a slope surface, and the silt discharging port 3 is arranged at the lowest side of the bottom surface of the separation cylinder 1. An inverted cone structure 6 is arranged between the water outlet 4 and the water inlet 2 in the separation barrel body 1, and a water passing hole is formed in the top of the inverted cone structure 6. The outer edge of the inverted cone structure 6 is connected with the inner wall of the separation cylinder 1 through a plurality of connecting plates 7. A gap is left between the outer edge of the inverted cone structure 6 and the inner wall of the separation cylinder 1.
When silt in the aquaculture wastewater is precipitated on the bottom surface of the separation cylinder body 1, the silt can be gathered at the lowest position of the bottom surface, namely the silt discharge port 3, along the inclined bottom surface because the bottom surface of the separation cylinder body 1 is a slope surface. When the silt discharging port 3 is opened, silt can be discharged out of the separation cylinder 1. The top of separation barrel 1 is equipped with delivery port 4 for the breed waste water in the discharge separation barrel 1, and through overflow exhaust mode, can effectually avoid the silt in the separation barrel 1 to enter into delivery port 4, thereby reduced delivery port 4 and the risk that the type of falling U pipe of being connected with delivery port 4 is blockked up. An inverted U-shaped pipe is arranged on the water outlet 4 and used for conveying the culture wastewater in the separation barrel body 1 to the solid-liquid separator.
Preferably, the inclination angle of the bottom surface of the separation cylinder 1 is 5 to 10 °. If the inclination angle of the bottom surface of the separation cylinder body 1 is too large, the accumulation amount of the bottom surface is reduced, and silt can be quickly accumulated to a position close to the water inlet 2. When the aquaculture wastewater discharged from the water inlet 2 impacts on the silt, the silt can be rolled up, and the separation effect is poor. If the bottom surface inclination angle of the separation cylinder 1 is too small, the discharge of silt is not facilitated. Therefore, the inclination angle of the bottom surface of the separation barrel body 1 is set between 5 degrees and 10 degrees, the problem that silt is rolled up can be effectively solved, the silt can be discharged conveniently, and the convenience and practicability of the separator are guaranteed.
Preferably, the inlet 2 is arranged opposite the silt discharge 3, to facilitate the overall arrangement of the separator.
Preferably, the top of the separation cylinder 1 is of a conical structure. When the aquaculture wastewater overflows from the separation barrel 1 to the water outlet 4, the conical top can guide the aquaculture wastewater, so that the aquaculture wastewater is discharged.
Preferably, the distance from the water inlet 2 to the top of the separation cylinder 1 is 1/2-3/5 of the height of the separation cylinder 1, so as to ensure the distance between the water inlet 2 and the sediment outlet 3, and effectively reduce the phenomenon that sediment accumulated at the bottom of the separation cylinder 1 is rolled up.
Preferably, a flowmeter is arranged on the inverted U-shaped pipe, a control valve 5 is arranged on the water inlet 2, and the flowmeter is connected with the control valve 5. The flowmeter is used for monitoring the flow of the aquaculture wastewater in the inverted U-shaped pipe. When the flow meter monitors that the flow in the inverted U-shaped pipe is inconsistent with the set flow, the flow of the aquaculture wastewater flowing into the separation barrel 1 can be adjusted through the control valve 5 on the water inlet 2, and therefore the flow in the inverted U-shaped pipe can be adjusted.
Preferably, a control valve is arranged on the silt discharging port 3.
The working principle of the utility model is as follows: the breeding wastewater enters the separation cylinder body 1 through the water inlet 2 and is precipitated and separated in the separation cylinder body 1. Silt with higher specific gravity in the aquaculture wastewater can be precipitated and accumulated on the bottom surface of the separation cylinder body 1. When the separation barrel body 1 is filled with the aquaculture wastewater, the aquaculture wastewater after precipitation and separation, suspended matters and semi-suspended matters with smaller specific gravity can be discharged through the overflow of the water outlet 4 above the separation barrel body 1, and the aquaculture wastewater flows into the concentration separator through the transmission of the inverted U-shaped pipe. When the control valve is opened, silt can be discharged from the silt discharging port 3.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the utility model, which will not affect the effect of the utility model and the practicability of the patent.
