The cylinder body can rotate on the fixing frame along the axis, and the surface of the cylinder body is cleaned by the cleaner. The motor is an electric device for driving the cylinder to rotate, is externally powered, and is externally provided with a PLC control box for controlling, so that the motor drives the cylinder to rotate for a fixed number of turns in a fixed period through a preset. Typically 1.5 or 2.5 turns to ensure that the filtering structure used in the entire cartridge can be used for filtering. Because during normal filtration, the sewage entering the cylinder is directly downward contacted with the filtering structure at the lower part of the cylinder under the action of gravity for filtration. The cylinder is horizontally placed in the water tank and is always stable when not driven by the motor, so that only the lower part of the cylinder is filtered during filtration. Through rotating 1.5 circles or 2.5 circles, the cleaner can clean the whole cylinder completely once, and the part at the lower side can be ensured to be converted at regular time, so that each part of the cylinder can be contacted with sewage for filtration in the whole filtration period, and the influence on the service life of the filtration structure due to the filtration of the part filtration structure is avoided.

The scraping blade can push the sludge deposited at the lower part of the cylinder upwards, so that the cleaning is convenient. Because the whole cylinder body is horizontally arranged, the general cylinder body is immersed below the water surface, and impurities below the water surface are blocked in the water in the cylinder body by the filter cover on the surface of the cylinder body. If the scraping blade is not arranged on the inner wall, the sludge immersed in the water cannot be brought to the upper part when the cylinder rotates, and is always remained in the water in the cylinder, so that the cleaning effect is poor.
Furthermore, the annular filter screen is provided with a fixed groove which is fixedly connected with the turntables at two sides and is parallel to the axis of the cylinder, one side of the filter cover is sunk into the fixed groove, the other opposite side of the filter cover is sunk into the fixed groove after winding the cylinder for a circle, and a fixed rod fixed through a bolt is embedded into the fixed groove for fixing and sealing; the outer curved surface of the rotary disc is provided with an annular pressing strip for pressing the side edge of the filter cover.

When the PLC control box is started to clean, the motor and the supercharger work simultaneously, the motor drives the cylinder to rotate, the valve at the water inlet of the supercharger is opened, and clean cleaning water enters the spray pipe and is sprayed out from the nozzle after being pressurized by the supercharger. Because the whole cylinder body is horizontally arranged, the general cylinder body is immersed below the water surface, and impurities below the water surface are blocked in the water in the cylinder body by the filter cover on the surface of the cylinder body. When the cylinder rotates, most of sludge deposited at the bottom is pushed upwards and brought out of the water surface by the strip-shaped scraping blade, and then the sludge on the surface is washed down by the washing water sprayed by the spray pipe and falls into the tray to be discharged, so that the washing process is completed.
The water treatment circulating system comprises a filter tank and a clean water tank which are mutually communicated through a pipeline, wherein the rotary drum filter is arranged in the filter tank, and the water inlet pipe penetrates through the filter tank and is communicated with the fish pond; an overflow pipe A with a water outlet end higher than the joint of the water inlet pipe and the cylinder body but lower than the plane of the opening of the filter tank is arranged on the water inlet pipe in the filter tank; a B overflow pipe with an opening plane lower than the plane of the opening of the filter tank is arranged on the sewage drain pipe; a sterilizer and a water supplementing pipe are arranged in the clean water tank, and a ball valve is arranged at one end of an opening of the water supplementing pipe in the clean water tank; the upper part of the clean water tank is provided with a return pipe for circularly feeding the supernatant into the fish pond, and the filter tank is also internally provided with a filler. The A overflow pipe can flow out into the filter tank through the A overflow pipe when serious water blocking in the barrel cannot enter the filter tank from the barrel or the water quantity in the water inlet pipe suddenly increases, so that equipment damage is avoided. When the water level in the whole filter tank rises faster in rainy days, the water level in the whole filter tank rises to a certain height and then enters the B overflow pipe to be discharged from the sewage drain channel by setting the proper height of the opening of the B overflow pipe.
The beneficial effects of the invention are as follows:
