In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification of the present application, and these technical solutions include technical solutions which make any obvious replacement or modification for the embodiments described herein.

The drawings attached to the present specification are schematic views for assisting the explanation of the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof. It should be noted that for the sake of clarity in showing the structures of the various components of the embodiments of the present invention, the drawings are not drawn to the same scale. Like reference numerals are used to denote like parts.

Fig. 1-4 show the sewage lifting device of an embodiment of the present invention, which includes:

the sewage tank 1 is used for storing sewage; the sewage tank shown in fig. 1 has a substantially rectangular parallelepiped structure, and is preferably made of plastic, which is water-resistant and water-impermeable. The size of the sewage tank needs to be determined according to the use scene.

The liquid pump is arranged in the sewage tank 1 and is used for pumping out sewage in the sewage tank 1 from a water outlet of the sewage tank 1; the liquid pump is used to pump sewage from a lower tank location to a higher drain, such as a municipal drain. In a preferred embodiment, the sewage lifting device further comprises a controller 3, the controller 3 is electrically connected with the liquid pump 2, and the operation state of the liquid pump 2 is controlled by the controller 3.

The solid-liquid separator 4, the solid-liquid separator 4 includes the separator body 41, there are first inlet pipes 42, second inlet pipes 43 and discharging tubes 44 on the separator body 41, the discharging tube 44 communicates with sewage tank 1; the separator shell 41 is also provided with an inspection device 45, the inspection device 45 comprises a flange 451, a sealing cover 452 and a locking piece, the flange 451 is communicated with the separator shell 41, the sealing cover 452 is connected with the flange 451 in a sealing mode through the locking piece, and an inspection opening of the flange 451 is sealed through the sealing cover 452. The solid-liquid separator can adopt a precipitation type, after sewage enters the separator shell from the water inlet pipe, solids are precipitated at the lower position of the separator shell due to the action of gravity, and liquid flows out from the water outlet pipe (the water outlet pipe is designed at a position away from the bottom of the separator shell by a certain distance, and is set according to precipitation requirements, such as 5 cm). The other solid-liquid separator adopts the filtering principle, a filter screen is arranged in a separator shell and is positioned between a liquid inlet position (close to a port of a water inlet pipe) and a liquid outlet position (close to a port of a water outlet pipe), the filter screen is utilized to intercept larger solid substances in sewage, and liquid passes through the filter screen and flows out from a water outlet. The solid-liquid separator can avoid sewage from blocking the liquid pump.

Because solid-liquid separator need maintain or maintain in the use, through pulling down from sewage hoisting device completely to maintain through the space of inlet tube or outlet pipe and separator casing inside intercommunication, there is the problem that the maintenance is comparatively loaded down with trivial details difficult, and the utility model discloses sewage hoisting device is owing to set up the maintenance device, can maintain through the access hole when solid-liquid separator breaks down, has the advantage of maintaining convenient and fast more.

When utilizing the utility model discloses when sewage hoisting device carries out sewage treatment, the first inlet tube of sewage accessible, second inlet tube enter into solid-liquid separator, realize the separation back of solid and liquid in solid-liquid separator, liquid flows to the sewage case by the outlet pipe, and with sewage by sewage incasement discharge when setting up the liquid pump operation in the sewage case, with sewage by the lower sewage case position pump sending of position to the higher drain pipe in position, like in the municipal drainage pipe.

In the embodiment of the sewage lifting apparatus shown in fig. 2-4, the locking member comprises a screw 453 and a nut 454, the flange 451 is provided with a first bolt hole 458, the sealing cover 452 is provided with a second bolt hole 459, the screw 453 passes through the first bolt hole 458 and the second bolt hole 459, and the nut is locked at one end of the screw 453. In one embodiment, the surfaces of the flange and the sealing cap that are connected to each other are smooth surfaces to facilitate sealing. The connection of the flange plate and the sealing cover is realized by utilizing the screw rod and the screw cap, and the sealing device has the advantages of convenient connection and easy sealing. In order to improve the sealing stability, the sealing glue can be smeared on the surface where the flange plate and the sealing cover are connected, but after the sealing cover is maintained and opened, the sealing glue needs to be smeared again in the reassembling process, and the sealing glue is complex. In a further preferred embodiment, a sealing ring is further included, which is disposed between the flange 451 and the sealing cap 452, and which is preferably a rubber sealing ring or a silicone sealing ring. In order to avoid a single sealing ring from failing (local damage or a local gap), in a preferred embodiment, the sealing ring comprises a first sealing ring 456 and a second sealing ring 457, the first sealing ring 456 has a larger diameter than the second sealing ring 457, and the first sealing ring 456 is arranged on the outer circumference of the second sealing ring 457. By arranging the double-layer seal, when one layer of seal ring is damaged, the other seal ring is still used for realizing the seal between the flange plate and the seal cover. In order to avoid the displacement of the sealing ring between the flange plate and the sealing cover and further cause the sealing failure, a groove is arranged on the flange plate 451 or the sealing cover 452 at a position corresponding to the sealing ring, and the sealing ring is arranged in the groove and protrudes out of the groove.

For the embodiment that the sealing ring is arranged between the flange plate and the sealing cover, the flange plate and the sealing cover press the sealing ring and deform the sealing ring to a certain extent through adjustment of the screw rod and the screw cap, so that the sealing ring is tightly attached to the surfaces of the flange plate and the sealing cover to realize sealing. However, since the seal ring is generally thin (within several millimeters), the above deformation amount is not large, and the elasticity of the seal ring is likely to be deteriorated after a long period of use, and further, a gap is formed between the seal ring and the surface of the flange or the surface of the seal cover, thereby causing leakage. In a further modification of the above embodiment, the service device 45 further comprises a spring 455, the spring 455 being fitted over the screw 453, the spring 455 being located between the sealing cap 452 and the screw cap. When the sealing cover is installed, the nut rotates to compress the spring towards the direction of the flange plate, so that the length of the spring between the sealing cover and the nut is shortened, and the sealing cover can be pressed by the spring to press the sealing ring between the flange plate and the sealing cover and deform the sealing ring to a certain extent; after long-term use, in time the sealing washer loses elasticity, still usable spring's elasticity realizes the good laminating between sealing washer and flange dish surface, the sealed lid surface, avoids taking place to leak. In the embodiment shown in fig. 3, the number of screws is 4, and the specific number of screws can be selected according to the connection requirement, and is usually at least 3, and the screws are uniformly arranged at intervals on the circumference.

The technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention to achieve the aim of the invention.
