Description

Sewage lifting device

Technical Field

The utility model relates to the technical field of sewage lifting, in particular to a sewage lifting device.

Background

With the increasingly developed material demands and environmental protection demands, most of the sewage generated in daily life production is required to be transported to a sewage treatment plant by a sewage lifting device. At present, there are two main types of sewage lifting devices in the market: one is simple lift pump + airtight header tank structure, and this kind of device's advantage is simple structure, low cost. But the defect is also obvious, the functions of dirt isolation and automatic back flushing are not available, various dirt can be often accumulated in the water collecting tank, manual frequent cleaning is needed, the lifting pump is easily blocked, the lifting pump is damaged, even if the lifting pump with the cutting function is expensive, the effect is also not ideal, the cutting knife is easily wound by flexible dirt such as hair, and the like, not only can not be cut up, but also is extremely easy to cause the blocking and burning of the submersible dirt pump.

The other lifting device realizes the functions of dirt isolation and automatic back flushing by using various dirt isolation devices, check valves, reversing valves and the like. Before sewage enters the water collecting tank, the sewage is isolated outside the water collecting tank, and when the lifting pump works, the sewage is reversely flushed into the conveying pipe network by using pressurized water. The device can well avoid the damage of dirt to the lifting pump or accumulation in the water collecting tank. However, the current mainstream lifting devices also have several disadvantages: (1) The adopted dirt separation device is used for separating dirt by utilizing filter screens with various specifications, the effect of the dirt separation device is not ideal, because the filter screens are easy to block and cause faults if too dense, the filter screens are required to be cleaned manually frequently, and the good separation effect cannot be achieved if too sparse; (2) The adopted check valves are check valves with valve cores or valve plates, and are easy to be damaged due to the fact that dirt is wound and blocked; (3) In order to achieve the back flushing function, sewage reversely flows into the water collecting tank from the water outlet of the lifting pump, so that the lifting pump is easy to reverse, and the service life of the lifting pump is influenced.

Therefore, it is desirable to provide a sewage lifting device to solve the above technical problems.

In the embodiment of the utility model, the sewage in the water collecting tank 1 flows into the sewage isolation mechanism 3 from the lift pump outlet 21 through the water collecting tank outlet water pipeline 6 under the pressure of the lift pump 2, and simultaneously, the external sewage is stopped from entering the sewage isolation mechanism 3, and as the flow rate of the water collecting tank outlet water pipeline 6 is far greater than that of the water collecting tank inlet water pipeline 7, the sewage can quickly fill the whole sewage isolation mechanism 3, and the rubber check valve 37 at the water pressure rising water outlet 36 in the sewage isolation mechanism 3 can be automatically opened, so that the sewage in the sewage isolation mechanism 3 flows out to be finally discharged into a sewage conveying pipe network.
