The working process and the principle thereof are as follows:

after the rubbish is placed in the landfill pond 1, sewage in the rubbish can permeate downwards and pass through the harmless geotechnical cloth in proper order, and after the cobblestone and some coal cinder in the pore layer are filtered, one part directly flows into the catheter 5 through the filtration hole 51 of the catheter 5, and the other part flows into the diversion layer firstly, flows into the filtration hole 51 along the inclined concrete bottom plate under the effect of the impermeable membrane, and finally flows into the catheter 5.

Sewage flows downwards along the inner wall of the liquid guide pipe 5, is scattered through the conical bottom structure and flows into the sewage tank 6, and due to the conical structure, the sewage can be prevented from directly flowing onto the cleaning brush 7 as much as possible, and the accumulation of oil sludge of the cleaning brush 7 is reduced.

After the sewage flows into the sewage tank 6, some substances in the sewage react with bacteria to produce a large amount of gas with the lapse of time, so that the air pressure inside the sewage tank 6 becomes large, the large air pressure acts on the piston 33 through the through hole 312 of the air cylinder 31, the piston 33 moves upward, and the spring 36 is compressed.

The piston 33 drives the lifting frame 25 to ascend through the connecting rod 34, the lifting frame 25 drives the lifting cylinder 23 to ascend, the lifting cylinder 23 is rotatably connected with the rotating shaft 21, the rotating shaft 21 can be driven to move upwards together, the spiral groove 211 is formed in the peripheral wall of the rotating shaft 21, the ball 231 of the limiting cylinder 22 slides in the spiral groove 211, a tangential acting force along the rotating shaft 21 is applied to the spiral groove 211, and the rotating shaft 21 can rotate correspondingly while ascending. Therefore, the cleaning brush 7 is raised while rotating, and the filter holes 51 in the inner wall of the liquid guide tube 5 can be cleaned to reduce clogging.

When the piston 33 moves to the highest point, the iron sheet 35 is connected with the two electric connecting posts 37, the electromagnet 32 is electrified, and the electromagnet 32 adsorbs the iron sheet 35, so that the piston 33 is fixed at the highest point. The exhaust pipe 313 is positioned at the bottom of the piston 33, and the exhaust pipe 313 communicates with the inside of the dirty water tank 6 to exhaust the excessive gas, and then the gas is purified by the exhaust gas treatment device and exhausted.

The time relay 38 controls the electromagnet 32 to be electrified for a period of time, and then the electrified circuit of the electromagnet 32 is automatically disconnected, so that the electromagnet 32 is powered off, the electromagnet 32 no longer adsorbs the iron sheet 35, and the piston 33 is reset under the action of the spring 36.

The cleaning brush 7 will rotate to clean the inner wall of the liquid guiding pipe 5 while descending. When the air in the sewage tank 6 becomes more, the cleaning brush 7 repeats the above process, thereby achieving the purpose of automatically cleaning the inner wall of the liquid guide pipe 5 and reducing the possibility of blockage of the filter hole 51.

When the water level in the sewage tank 6 becomes high, buoyancy acts on the float 41 to jack the slide rod 42, so that the baffle 43 at the top of the slide rod 42 touches the trigger switch 44 to cause the alarm to give an alarm, and a maintainer is reminded of draining the sewage tank 6 in time and carrying out concentrated purification treatment on sewage.
