Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the dual-pump backwashing system of the sewage lifting tank comprises a tank body 1 and a controller 2, wherein the tank body 1 is provided with a water inlet 11 and a drainage mechanism 12, the drainage mechanism 12 comprises two water outlet pipes 121, a collecting pipe 122 and two water pumps 123, the two water outlet pipes 121 are arranged in parallel, one part of the water outlet pipe 121 extends into a low position in the tank body 1, the other part of the water outlet pipe 121 is connected with the collecting pipe 122 outside the tank body 1, so that the two water outlet pipes 121 and the collecting pipe 122 form a conveying channel for discharging sewage outwards, further, the collecting pipe 122 is two main pipes 121, the two water outlet pipes 121 are two branch pipes 122, the two water pumps 123 are respectively arranged on the two water outlet pipes 121 extending into the tank body 1, a backwashing pipe 4 is arranged between the two water outlet pipes 121, and a valve 5 is arranged on the backwashing pipe 4, and a second valve 6 is arranged on the collecting pipe 122, and the controller 2 is used for controlling the operation of the two water pumps 123.

In the embodiment, the water pump 123 is installed at a low position of the water outlet pipe 121 in the tank body 1, and a water suction space 32 is reserved between the water suction port 31 of the water pump 123 and the bottom of the tank body 1, so that sewage can be discharged better.

The water pump 123 is installed on the water outlet pipe 121 in the box body 1 through a coupler 7, so that the water pump 123 can be better butted with the water outlet pipe 121, meanwhile, in order to facilitate installation and adjustment of the installation height position of the water pump 123, the water pump 123 is installed on the side wall in the box body 1 through the vertical guide rail 8, and under the action of the vertical guide rail 8, up-and-down moving type fixed installation is formed, the vertical rail 8 is a straight pipe fixed on the inner wall of the box body 1, and the water pump 123 is installed on the vertical rail 8 through the coupler 7, so that the installation and maintenance are convenient, the water pump 123 can be installed at a preset height position, and in order to avoid influence on use caused by the fact that sewage in the box body 1 cannot be timely discharged, an overflow port 9 is arranged.
