[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-5 For this type of rural sewage filtration and separation device, when in use, the water inlet 10 at the top corner of the treatment tank 1 is first used for the inflow of rural sewage. The sewage flows into the treatment tank 1. Since the treatment tank 1 is divided into multiple working chambers, the first thing to pass through is the crushing chamber 2 at the top of the treatment tank 1. The motor 9 in the middle of the surface of the treatment tank 1 drives the crushing knife 901 below to run at a high speed inside the treatment tank 1. The sewage mixed with solid foreign matter pours into the water inlet 10, and the crushing knife 901 will crush the solid foreign matter therein. The crushed solid foreign matter and sewage will fall into On the filter plate 3 below, sewage will flow into the water collecting funnel 4 below through the holes on the filter plate 3, and the broken solid foreign matter will be screened and retained on the filter plate 3. After use, the solid foreign matter on the filter plate 3 can be cleaned by pulling it to the outside. The water collecting funnel 4 is arranged below the filter plate 3 to collect the sewage passing through the filter plate 3, and the bottom of the water collecting funnel 4 below is connected to the purifier 5 to purify the filtered water. The purified water flows into the water storage chamber 7 below and can be precipitated again. Due to the precipitation chamber 6 The water storage chamber 7 is the same cavity space, and the upper part of the same space is used as the water storage area after sedimentation, and the bottom of the space is the sedimentation area for static sedimentation sludge, so the precipitated debris sludge can sink to the bottom sedimentation chamber 6, the outlet pipe 11 is installed on the outside of the corresponding water storage chamber 7, and the mud discharge pipe 601 is installed on the outside of the corresponding sedimentation chamber 6, so the water stored in the upper water storage chamber 7 can be taken or discharged through the outlet pipe 11 on one side in conjunction with the valve 12 switch, and the water in the upper water storage chamber 7 is discharged by the discharge pipe 11. After discharge, the sludge in the sedimentation chamber 6 can be discharged through the sludge discharge pipe 601.
