Automatic sewage lifting device with oil-separating apparatus

Abstract

The invention discloses an automatic sewage lifting device with an oil-separating apparatus, which has the functions of automatic sewage lifting and simple oil separation. The automatic sewage lifting device disclosed by the invention is characterized in that a water inlet is in butt joint with a water outlet by a flange; a feed water check valve and a four-way water distributor are connected by a special hole and a flange; a discharge water check valve is in flanged joint with a discharge pipe; a solid-fluid separator is in flanged joint with a pipe; and the bottom of the solid-fluid separator is provided with a hole, welded with the pipe and then in flanged joint with a submersible sewage pump. The automatic sewage lifting device disclosed by the invention has the advantages of environment friendliness, health and space saving.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to automatic sewage lifting equipment with an oil separation device. Background technique [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...

[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
