detailed description

Below in conjunction with accompanying drawing, the utility model embodiment is further described:

As shown in the figure, an external pipeline sewage lifting device includes a water collection tank 1, a sewage pump 2, a residue storage 3, a water inlet pipeline 4, a drainage pipeline 5, and a backwash pipeline 6; one end of the water inlet pipeline 4 Connect to the sewage source, the other end is connected to the residue storage 3, and the first check valve 8 is also provided on the water inlet pipe 4; one end of the drainage pipe 5 is connected to the residue storage 3; the sewage pump 2 is arranged in the water collection tank 1, and connect the residue storage 3 through the backwashing pipeline 6; wherein, the residue storage 3, the water inlet pipeline 4, and the drainage pipeline 5 are all arranged on the outside of the water collection tank 1, and the residue storage 3 and the water collection tank 1 is provided with a filter 7, and the bottom side of the residue storage 3 is also provided with a sewage outlet 9.

The waste water enters the residue storage 3 from the water inlet pipe 4, and the solid waste remains in the residue storage 3 through the filter 7, and the water enters the water collection tank 1 through the filter 7. When the water level in the water collection tank 1 reaches a certain position At this time, the sewage pump 2 will start, and the water in the water collection tank 1 will be pumped out and sent to the backwash pipeline 6, and the backwash pipeline 6 will send the water into the residue storage 3. At this time, the first check valve on the water inlet pipeline 4 8 prevent sewage from flowing back, and discharge outwards from the drainage pipe 5. The residue storage 3, the water inlet pipe 4, and the drainage pipe 5 are all arranged on the outside of the water collection tank 1, so that the installation and connection are easier.

At the same time, the bottom side of the residue storage 3 is also provided with a sewage outlet 9. When the residue storage 3 has too much solid waste residue, the sewage outlet 9 is opened to facilitate cleaning, which is more convenient and better.

Further, the filter 7 is a steel plate with filter holes, which is not only more convenient to install, but also more reliable, better in quality and longer in service life than the ordinary filter mesh structure.

As shown in the figure, there are two residue storages 3, and the water inlet pipe 4 and the drainage pipe 5 both have a three-way pipe structure, and it is more efficient to arrange two residue storages 3 .

Correspondingly, two sewage pumps 2 are provided, and are correspondingly connected to two residue storages 3 through backwashing pipelines 6 .

As shown in the figure, an automatic coupler 10 is also provided, and the automatic coupler 10 is respectively connected with the sewage pump 2 and the backwashing pipeline 6, which is easier to install or disassemble.

Further, a second check valve 11 is provided between the automatic coupler 10 and the backwash pipeline 6 to prevent backflow.

As shown in the figure, the water collecting tank 1 is also provided with a liquid level controller 12, which can effectively control the water level in the water collecting tank 1 and timely control the start of the sewage pump 2.

As shown in the figure, the water collection tank 1 is provided with an overflow port 13 near the upper part, so as to avoid the problem of excessive water level when the sewage from the inlet pipe enters rapidly.

As shown in the figure, the bottom of the water collection tank 1 is also provided with a drain valve 14, and the filter 7 can only achieve preliminary filtration, but cannot completely filter, and the residue entering the water collection tank 1 through the filter holes will remain at the bottom of the water collection tank 1 , when the residue is accumulated too much, the residue is cleaned up through the blowdown valve 14 .

As shown in the figure, the top of the water collecting tank 1 is also provided with a sealing cover 15, and the sealing cover 15 is provided with a handle 16. When the sealing cover 15 is closed, the water collecting tank 1 is effectively isolated from the outside world. The sealing cover 15 is opened.

The embodiment should not be regarded as limiting the utility model, but any improvement based on the spirit of the utility model should be within the protection scope of the utility model.
