Problems solved by technology

[0002] At present, the usual method for the discharge of domestic sewage and waste water is to set up a sump on the basement floor, collect the sewage from sanitary ware together, and use a submersible pump to lift and discharge it to an outdoor underground sewage pump well, or drain the sewage from the toilet Self-flow into the outdoor underground sewage pump well, and then use the submersible sewage pump to lift and discharge into the sewage inspection well near the pump well; these common methods have the following disadvantages: 1. There are solid substances such as feces in the sewage, which will easily cause blockage if it is not cleaned for a long time , not easy to clear out; 2. Due to the shallow sump, the operation of the submersible sewage pump that starts and stops according to the water level is not reliable; 3. The airtightness of the sump is not good, there is smell, and the sanitary condition is poor; 4. Outdoors To build a pump well, the depth is deep, the investment is large, and the management is inconvenient

Embodiment Construction

[0018] like figure 1 As shown, in the sewage automatic lifting equipment with oil separation device provided by the present invention, the water inlet and water outlet of the equipment are connected through flanges; the water inlet check valve and the four-way water distributor are connected through special openings and flanges; the water outlet The check valve is flange-connected to the outlet pipe; the solid-liquid separator and the pipeline are flange-connected; the welded pipeline at the bottom of the solid-liquid separator is flange-connected to the submersible sewage pump.

[0019] The basement sewage enters the four-way water distributor of the equipment, and the two sides divert through the water inlet check valve and flow into the solid-liquid separator. The particles in the sewage are intercepted, and the sewage flows into the water inlet of the submersible sewage pump through the holes of the filter. It flows out from the bottom of the impeller of the submersible se...
