[0006] Furthermore, two collecting tanks are provided and are connected via a connecting pipe.

[0007] Furthermore, the collection tank is a vertical cylindrical tank with a volume of 15m 3 , the main body material is carbon steel.

[0008] Furthermore, the water inlet is arranged at -0.3m below the floor surface.

[0009] Furthermore, the water inlet valve, water outlet valve and sewage discharge valve are all manual butterfly valves.

[0010] Furthermore, the control box is arranged above the floor surface.

[0011] Furthermore, four sewage sedimentation tanks are provided.

[0012] This device is divided into primary and secondary collection tank groups, and the effective volume of a single tank is 15m 3 , the effective volume of the double tank is 30m 3 The installation form of the double tank is an integrated combination, and the main body material is carbon steel with internal and external corrosion resistance. This device is installed outdoors in the ground, and the electrical equipment is explosion-proof.

[0013] The system's sewage and venting water are all collected into the primary collection tank through the sewage pipeline, entering from 0.3m below the floor. When the water level in the primary collection tank rises to the middle of the tank, it flows into the secondary collection tank through the connecting port of the primary and secondary tanks. In the secondary tank, a submersible lift pump and a set of magnetic float flap level gauges are installed on the top. When the liquid level in the secondary tank rises to the high liquid level, the system transmits the high liquid level signal to the control system, and the control system issues a command to start the submersible lift pump at the same time. After all the sewage is pressurized, it is pumped into the sewage sedimentation tank for recovery and treatment. When the water level drops to the low liquid level, the system instructs the submersible lift pump to stop running and sends out an audible and visual alarm. This reciprocating operation ensures that the sewage collection device can be fully automatic and unattended.

[0014] The underground sewage collection device is designed with an effective capacity of 30m 3 , the overall dimensions are φ2600×H2800mm, there are 2 seats in total, and the effective volume of each seat is 15m 3 , divided into one and two stages in series operation, integrated combined installation, the main body is made of carbon steel, the inside and outside of the tank body are sandblasted and rusted to Sa2.5 level, and then anti-corrosion paint is applied; an explosion-proof submersible lifting pump is installed on the top of the collection device tank, the submersible part is made of reinforced polypropylene, the pump shaft is made of steel lined with PTFE, the motor power is 4.0KW, and the flow rate is 30m 3 / h, head 25m, explosion-proof grade ExdIIBT4, total quantity 1 unit; a set of magnetic float flap level gauge is also installed on the tank top, showing the liquid level is 1.5m, equipped with high and low liquid level sensors; equipped with 1 explosion-proof automatic control box, installed outdoors in front of the collection device, about 1.0m above the floor surface.
