[0024] Example 1

[0025] like Figs. 1-3 As shown, this embodiment provides an aquaculture filtration device, including a tank 1, a floating layer 2, a sensing device 18, a backwashing device 19, a sewage discharge device 20, an electrical control box 6, and a media partition 15. The tank 1 is provided with an inlet 7, an outlet 8, and a sewage discharge outlet 9. The floating layer 2 is disposed inside the tank 1, and the sewage discharge outlet 9 is disposed at the bottom of the tank 1. The sensing device 18 includes a pressure sensor 3 or a liquid level sensor 4. The backwashing device 19 includes an aeration device 10 and an air pump 11. The aeration device 10 is connected to the air pump 11 through a pipe and is disposed below the floating layer 2. The sewage discharge device 20 includes a sewage pump 12 or an electrically controlled valve 13. The sewage discharge device 20 and the sewage discharge outlet 9 are connected through a pipe. The electrical control box 6 is connected to the sensing device 18, the air pump 11, and the sewage discharge device 20 through wires.

[0026] Furthermore, the floating layer is provided with a filter medium 14, which is composed of plastic particles with a density less than that of water. In this embodiment, polyethylene plastic particles with a density less than that of water are used as the filter medium 14. When water is injected into the tank 1, the plastic particles will float on the surface of the water and press against each other to form a floating layer 2. The floating layer 2 is composed of many small plastic particles, and water can only permeate through the gaps between the particles. Larger impurity particles will be intercepted below the floating layer 14.

[0027] Furthermore, a water pump 16 is provided at one end of the water inlet 7. The water pump 16 is connected to the electrical control box 6 via a wire, and the electrical control box 6 controls the start or stop of the water pump 16.

[0028] Furthermore, the outlet 8 is disposed within the media partition 15, which is configured as a plate-shaped perforated porous structure or a cylindrical perforated porous structure to prevent the filter media 14 from passing through the outlet 8. When water is injected into the tank 1, the water passes through the floating layer 2, and the clarified water is squeezed out above the floating layer 2 and flows out of the device through the outlet 8, while the filter media 14 is blocked outside the media partition 15 to prevent loss.

[0029] Furthermore, the electrical control box 6 is equipped with a time controller or a programmable controller, which controls the start or stop of the air pump 11, the sewage pump 12, and the electrically controlled valve 13, respectively. The time controller or programmable controller in the electrical control box 6 can control the start and stop of the air pump 11, the sewage pump 12, and the electrically controlled valve 13 individually or in combination. It can also achieve timed or delayed start and stop by inputting commands through the programmable controller buttons or setting programs.

[0030] Furthermore, the tank 1 is provided with a connecting pipe 5, which communicates with the tank 1. The pressure sensor 3 is disposed inside the tank 1 or on the connecting pipe 5, and is connected to the electrical control box 6 via a wire. The sensing signal of the pressure sensor 3 is transmitted to the control cabinet 6 via the wire, thereby causing the control cabinet 6 to execute the corresponding control start and stop procedures.

[0031] Furthermore, the tank 1 is equipped with a liquid level pipe 17, and the liquid level sensor 4 is disposed inside the liquid level pipe 17. The liquid level sensor 4 is connected to the electrical control box 6 via a wire. The sensing signal of the liquid level sensor 4 is transmitted to the control cabinet 6 via the wire, thereby causing the control cabinet 6 to execute the corresponding control start and stop program.

[0032] Furthermore, the aeration device 10 includes an aeration disc or an aeration pipe. In this embodiment, an aeration disc is used. The aeration disc is connected to the air pump 11 through a pipe. When the air pump 11 is started, a large amount of gas is emitted from the aeration disc, causing the water in the tank 1 to tumble and achieve backwashing of the medium 14.

[0033] Furthermore, the electrically controlled valve 13 is composed of an electrically controlled push rod valve or a solenoid valve. In this embodiment, the electrically controlled valve 13 is composed of a solenoid valve, and the opening and closing of the solenoid valve is realized through the program of the electrical control box 6, thereby realizing the timed sewage discharge of the tank 1.

[0034] The working principle and process of this embodiment are as follows:

[0035] In traditional filtration systems, after the brush chamber intercepts fine particles, the brushes become very dirty over time. This requires regular manual cleaning, typically involving draining the water from the brush chamber and then removing the brushes and rinsing them with a high-pressure water jet. In this embodiment, the coordinated operation of the various components enables automatic backwashing and automatic wastewater discharge.

[0036] The specific steps are as follows:

[0037] Step A: The water pump 16 operates, transporting water containing fish waste into the tank 1. The low-density filter medium 14 in the tank 1 floats to the surface, forming a filter floating layer 2 with very small water passage gaps. The water permeates through the floating layer 2 under the pressure of the water pump 16, while fish waste and other impurity particles remain in the tank 1. The filtered water is discharged from the outlet 8.

[0038] Step B: As time goes by, the floating layer 2 intercepts more and more fish waste particles, which leads to a decrease in the water flow performance of the floating layer 2, an increase in water pressure in the tank 1, and a rise in the water level in the level pipe 17. When the water pressure reaches the set value, or the water level reaches the position set by the level sensor 4, the sensor will be triggered, causing the pressure sensor 3 or the level sensor 4 to send a signal to the control box 6, so that the control box 6 can perform backwashing and sewage discharge according to the set program.

[0039] Step C: After receiving the feedback signal, the control box 6 shuts down the water pump 16 according to the program and starts the air pump 11. After the air pump runs for the set time, it stops. Then, the sewage pump 12 or the electrically controlled valve 13 opens and discharges sewage for the set time before closing. In this embodiment, the backwashing time is set to 5 minutes, and the sewage discharge time is set to 5 minutes. Therefore, the air pump stops after running for 5 minutes, and then the sewage pump 12 or the electrically controlled valve 13 opens for 5 minutes. After 5 minutes, the sewage pump 12 or the electrically controlled valve 13 closes, and the sewage discharge is completed. At this time, the control box 6 restarts the water pump 16 to enter the next round of filtration and backwashing cycle.

[0040] This embodiment completes the filtration and backwashing of aquaculture wastewater through the above-described steps A to C, thereby achieving fine water filtration and automatic wastewater discharge.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
