DETAILED DESCRIPTION

[0021] The foregoing and other technical contents, features and effects of the utility model will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. Figures 1-4 The structural contents mentioned in the following embodiments are all referred to the drawings.

[0022] The exemplary embodiments of the utility model will be described below with reference to the accompanying drawings.

[0023] Embodiment 1, a sewage lifting device, comprising a box body 1, characterized in that:

[0024] The box body 1 is detachably connected with a mounting plate 2, the mounting plate 2 is provided with a sewage inlet pipe 3 at the top and a crushing cylinder 4 at the bottom, the crushing cylinder 4 is provided with a plurality of crushing holes 5, the mounting plate 2 is rotatably connected with a crushing knife 6, and the crushing knife 6 is driven by a power device.

[0025] The box body 1 is provided with a sewage outlet pipe 7 on the side away from the sewage inlet pipe 3;

[0026] The bottom of the box 1 is detachably connected with a bottom plate 8, a plurality of filter plates 9 are arranged on the bottom plate 8, and a plurality of filter holes 10 are arranged on each filter plate 9.

[0027] The filter holes 10 arranged on the filter plates 9 close to the crushing cylinder 4 are arranged in a diameter from large to small to the filter holes 10 arranged on the filter plates 9 close to the sewage outlet pipeline 7.

[0028] As an alternative of the embodiment 1, two groups of connecting plates 11 are arranged on the box 1, and the two groups of connecting plates 11 are slidingly connected with positioning blocks 12 matched with the mounting plate 2, a handle 13 is arranged on the positioning block 12, and a reset spring 14 is arranged between the handle 13 and the connecting plate 11.

[0029] As an alternative of the embodiment 1, the bottom plate 8 is connected with the box 1 through a buckle 15.

[0030] As an alternative of the embodiment 1, the power device comprises an electric motor 16 fixedly connected on the mounting plate 2, the crushing knife 6 is driven by the electric motor 16, and the electric motor 16 is electrically connected with the controller.

[0031] As an alternative of the embodiment 1, a sealing ring is arranged between the bottom plate 8 and the box 1.

[0032] In actual application, sewage enters from the sewage inlet pipeline 3, the sewage outlet pipeline 7 is connected with a water pump, the sewage enters into the crushing cylinder 4, the driving electric motor 16 drives the crushing knife 6 to crush the large sundries entering into the crushing cylinder 4, and then falls into the box 1 through the crushing hole 5, and is filtered through the three layers of filter plates 9, the filter holes 10 of the three layers of filter plates 9 from left to right are filtered in a diameter from large to small, and the maximum diameter of the filter holes 10 arranged on the filter plates 9 is not greater than the diameter of the crushing hole 5; thereby realizing three-stage filtration, ensuring that the sewage discharged from the sewage outlet pipeline 7 will not appear large sundries, avoiding the blockage of the pump body, and improving the efficiency of sewage discharge;
