Working principle:
When domestic sewage enters the filtering feeding mechanism 3, solid matters in the filter residue piece 33 can be filtered, the gear pump 35 pumps the sewage into the lower end of the cavity of the sewage filtering pool 211 through the sewage inlet pipe 34, when the sewage level slowly rises, when the sewage level passes through the sewage isolating filter screen group 4, the sludge can be isolated from the lower part by the sewage isolating filter screen 42, and is precipitated below and flows into the sewage tank group 22, water and an oil layer can upwards pass through the upper part of the cavity of the sewage filtering pool 211, under the action of the sewage isolating filter screen group 4, the fluctuation of a water oil layer at the upper end of the cavity of the sewage filtering pool 211 can be small, when the oil level sensor 212 senses that the oil level reaches the position a1 (see figure 1), the air filling pump 56 on the air blowing oil scraping mechanism 5 blows with small frequency, so that a small amount of air blows the oil layer to the right, the oil layer flows to the oil layer pipe group 23 and enters the right end cavity of the sewage filtering pool group 6, in the process, the motor 54 drives the screw rod 52 to drive the air filling nozzle group 55 to move rightwards to match, the knocking ball 58 can also be pulled upwards, the knocking ball 58 can be blown into the water draining mechanism to swing the sewage draining pipe 2 in sequence, the water draining mechanism is blown down with the water level of the sewage draining mechanism 4, and the water draining mechanism is blown down with the water level of the sewage draining mechanism 2 in sequence, and the water draining mechanism is blown down by the water tank is blown into the sewage draining tank 2.
In addition, when the oil layer is scraped and flows into the oil filtering pool group 6, the oil layer is firstly separated from the left cavity of the oil filtering pool 61, so that water is precipitated into the first water precipitation tank 64, the oil on the upper layer overflows into the right cavity of the oil filtering pool 61 through the flat oil overflow pipe 63, and under the action of the submerged inclined plate, the oil can only flow rightwards from the lower end of the submerged inclined plate, and in the process, a trace amount of water can sink into the second water precipitation tank 65, and finally the oil overflows into the oil collecting barrel 7 from the second oil overflow pipe 66.
When all the water and oil in the sewage tank 211 and the oil tank 61 are to be pumped out, it is also necessary to operate through the drain pipe on the sewage tank set 22 and the first sewage tank 64.
