[0028] like Figure 1-4 As shown, this embodiment provides a marine aquaculture water circulation system, including an aquaculture pond 1 and a filter regulating component 3 connected thereto. The filter regulating component 3 is equipped with a lift pump, which transports the pre-filtered wastewater to a first wastewater treatment device 5 of the purification treatment device for preliminary purification. The pre-purified wastewater is then transported to a second wastewater treatment device 6 for further purification by the lift pump. After reaching the purification standard, the wastewater is transported to a circulation pipe group 4 by the lift pump and then to the aquaculture pond 1 through the circulation pipe group 4. A high-pressure pump 2 is installed on the pipe of the circulation pipe group 4.

[0029] Furthermore, both the first sewage treatment equipment and the second sewage treatment equipment 6 can be common sewage purification equipment on the market. The second sewage treatment equipment 6 is equipped with an aeration device that supplies oxygen to the sewage inside to support aerobic microorganisms in the water to degrade organic matter. The aeration device 7 is preferably blower aeration.

[0030] Furthermore, the filtration and regulation assembly 3 includes a filtration and regulation tank 033, inside which a filter plate 039 is provided. The filter plate 039 has multiple sets of filter holes 0391, which block solid particles (such as feed, excrement, sand particles, etc.) in the sewage. The outlet of the filtration and regulation tank 033 is connected to a connecting pipe 0314, which is connected to a filter screen cylinder 031, and water is transported into the filter screen cylinder 031 through the connecting pipe 0314.

[0031] Furthermore, the filter screen cylinder 031 adopts a filter drum screen with a built-in sieve, and the sieve is driven by the drive system 0315. The filter screen cylinder 031 is provided with a drug inlet 0312 for adding drugs into it. The filter screen cylinder 031 also includes a water outlet end 0311, and the water outlet end 0311 is connected to the water inlet port of the lift pump provided in the filter adjustment assembly 3.

[0032] In practical applications, wastewater contains organic matter and microorganisms, which can deposit along with minerals in the water, adhering to the surface of filter plate 039 and clogging the filter pores. To solve the above technical problems, please refer to [link to relevant documentation]. Figure 2-4 Two sets of oppositely arranged flushing pipes 0352 are installed at the top of the filter regulating tank 033, which is located away from the filter screen cylinder 031. The inlet ends of the two sets of flushing pipes 0352 are connected to the liquid conveying bend 0354, and are connected to the water storage tank 038 fixedly installed on the side wall of the filter regulating tank 033 through the liquid conveying bend 0354.

[0033] A control valve 0353 is installed on the liquid delivery bend, and the control valve 0353 is an electromagnetic control valve; in order to improve the flushing effect, a high-pressure water pump 0355 can be installed on one or two sets of liquid delivery bends.

[0034] Furthermore, the outlet end of the flushing pipe 0352 is connected to the gas delivery pipe 0341, and the other end of the gas delivery pipe 0341 is connected to an external gas delivery device. A high-pressure gas pump 0342 is installed on the gas delivery pipe 0341, and at least one set of nozzles 8 is installed on the flushing pipe 0352.

[0035] In this embodiment, by delivering high-pressure gas into the flushing pipe 0352, a gas-water mixture is generated, which makes the gas-liquid mixture sprayed through the nozzle have a stronger impact force, thereby effectively removing the deposits adhering to the filter plate and improving the cleaning effect.

[0036] Furthermore, the nozzle 8 includes a spray pipe 083, and a baffle plate 081 is provided at the inlet end of the spray pipe 083. The baffle plate 081 is detachably connected to the spray pipe 083, and a spray inlet 082 is provided on the baffle plate 081. By adding a baffle plate with a spray inlet 082, the water flow channel can be restricted, causing the water flow to generate a certain pressure and velocity when passing through the spray inlet. The flow velocity increases when the water flows through a smaller spray inlet.

[0037] Furthermore, the outlet end of the spray pipe 083 is connected to a tee connector 085, and is connected to a spray ball 084 through the tee connector 085. The spray ball 084 has a spray groove 086 arranged in a tandem shape.

[0038] In this embodiment, the spray grooves 086 arranged in a 360° shape enable the spray balls 084 to achieve 360° cleaning without dead angles.

[0039] Furthermore, a stirrer 037 is provided in the filter conditioning tank 033 located below the filter plate. The stirrer 037 includes a rotary motor 0371. The drive shaft of the rotary motor 0371 is connected to the stirring shaft 0372 through a bearing assembly. The stirring shaft 0372 is provided with multiple sets of stirring blades 0373 that extend continuously along its longitudinal direction.

[0040] In this embodiment, some impurities may enter the filtration conditioning tank through the filter holes of the filter plate. By starting the rotary motor 0371, the rotary motor 0371 drives the stirring blades 0373 on the stirring shaft to rotate, thereby keeping the unfiltered impurities in the water and preventing them from settling at the bottom of the filtration conditioning tank. This allows them to enter the next process filter screen cylinder for further filtration through the water flow, thereby improving the filtration effect.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
