[0025] In the embodiment, the output end of the extension assembly 13 is equipped with a push rod penetrating the filter box 6 and connected with the pressing plate 14.

[0026] In the field of high-density aquaculture, effective collection of excrement is a key link to guarantee the quality of aquaculture environment and aquatic products. The underwater operation's fishery excrement suction device provided by the utility model innovatively designs for the problems existing in traditional excrement suction devices, effectively improves the excrement suction efficiency and reduces the subsequent processing difficulty.

[0027] (I) excrement suction process:

[0028] When the device is started, the liquid suction pump 11 starts to work, and strong suction is generated at the suction pipe 4. The suction pipe 4 is located on the manure suction box 3, and the manure suction box 3 is placed at the bottom of the manure settling tank 1 and is in sliding connection with the second guide rod 2. The strong suction can suck the sewage containing manure impurities at the bottom of the manure settling tank 1 into the manure suction box 3, and then the sewage is transported to the butt joint seat 8 at the top of the filter box 6 through the first conduit 5, and finally enters the pollution collection filter bag 9.

[0029] (II) Filtration and liquid backflow:

[0030] After the sewage enters the pollution collection filter bag 9, the manure impurities are intercepted in the bag, and the excess liquid passes through the pollution collection filter bag 9 into the second conduit 12. These liquids flow into the input end of the liquid suction pump 11 along the second conduit 12, and then are reflowed into the manure settling tank 1 through the drain pipe at the output end of the liquid suction pump 11, realizing the recycling of water resources and reducing waste.

[0031] (III) Extrusion dewatering:

[0032] When a certain amount of manure impurities accumulates in the pollution collection filter bag 9, the telescopic assembly 13 (using a gas cylinder) on both sides of the filter box 6 is started. The push rod at the output end of the gas cylinder penetrates the filter box 6 and pushes the pressing plate 14, extruding the pollution collection filter bag 9. Under the extrusion of the pressing plate 14, the excess water remaining in the pollution collection filter bag 9 is further squeezed out through the second conduit 12, so that the water content of the collected manure impurities is reduced, reducing the burden of subsequent treatment.

[0033] Movement of the manure suction box 3:

[0034] In this embodiment, the top frame 17 is fixed above the manure suction box 3 through the vertical rod 20, the manure suction box 3 is fixed at the lower end of the vertical rod 20 through a screw, and the top frame 17 is fixed at the upper end of the vertical rod 20 through a screw.

[0035] If it is necessary to perform manure suction operation on different areas of the manure settling tank 1, the motor 16 (using a servo motor) installed on one side of the support rod is started. The threaded rod 18 at the output end of the motor 16 penetrates the top frame 17 and is in threaded connection with the top frame 17, and the top frame 17 is in sliding connection with the first guide rod 19, which spans between the two support rods. When the motor 16 operates, the threaded rod 18 rotates, driving the top frame 17 to move along the first guide rod 19. Since the top frame 17 is fixedly connected with the manure suction box 3 through the vertical rod 20, the manure suction box 3 will move along the second guide rod 2 at the bottom of the manure settling tank 1, thereby realizing the collection of manure in different areas and improving the comprehensiveness and flexibility of manure suction.

[0036] The flow rate of the liquid suction pump 11 is generally set to 5-15 cubic meters per hour according to the size of the feces settling tank 1 and the breeding density, so as to ensure efficient suction of sewage and prevent fecal impurities from being difficult to intercept by the pollution collection filter bag 9 due to excessive flow rate.

[0037] The power of the motor 16 is generally between 0.5-1.5 kilowatts according to the weight of the feces suction box 3, the moving friction, and the moving speed requirement, which can provide sufficient power for the stable movement of the feces suction box 3 and achieve precise speed and position control.

[0038] The working pressure of the air cylinder is generally set to 0.4-0.6 megapascals, which can generate sufficient extrusion force on the pressing plate 14 to effectively extrude the pollution collection filter bag 9 and squeeze out the water therein, while not damaging the bag due to excessive pressure.

[0039] (1) Efficient solid-liquid separation:

[0040] By filtering the sewage through the pollution collection filter bag 9, fecal impurities can be effectively intercepted, significantly reducing the water content of the collected feces and greatly reducing the difficulty and cost of subsequent treatment, such as reducing the energy consumption and maintenance cost of the dewatering equipment.

[0041] (2) Water resource recycling:

[0042] The device recirculates the filtered liquid back to the feces settling tank 1, achieving water resource recycling, reducing water waste, meeting environmental protection and sustainable development requirements, and reducing water costs during breeding.

[0043] In this embodiment, the side plate 7 is fixed to one side of the filter box 6 by screws, and the butt joint seat 8 is inserted into the inside of the butt joint ring 10 and threadedly connected with the butt joint ring 10.

[0044] The motor 16 drives the movement of the feces suction box 3, which can perform feces suction operations in different areas of the feces settling tank 1, improving the comprehensiveness and flexibility of feces suction. At the same time, the feces suction box 3, the top frame 17, and the vertical rod 20 are fixed by screws, the side plate 7 of the filter box 6 is fixed by screws, and the butt joint seat 8 of the pollution collection filter bag 9 is threadedly connected with the butt joint ring 10, which facilitates the installation, disassembly, and maintenance of the device, facilitates the cleaning of the pollution collection filter bag 9, and improves the work efficiency.

[0045] In this embodiment, the motor 16 is a servo motor, and the telescopic assembly 13 is an air cylinder.

[0046] The servo motor and the air cylinder are used as power sources, precise control can be realized, the servo motor can accurately control the moving speed and position of the excrement suction box 3, the air cylinder can accurately control the extrusion degree of the pressing plate 14, the stability and efficiency of the excrement suction and extrusion dehydration process are ensured, and the reliability and stability of the device are improved.
