The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] An integrated silent and non-clogging sewage lifting device, such as Figure 1-3 As shown, it comprises a lifting shell 1, a lifting impeller 3 is rotatably connected inside the lifting shell 1, and the lifting impeller 3 and the lifting shell 1 are rotatably connected via a rotating shaft 2;

[0024] One end of the lifting shell 1 is fixedly connected to the water inlet pipe 4, and one end of the rotating shaft 2 is fixed with a transmission shaft 5 located inside the water inlet pipe 4. The outer side of the transmission shaft 5 is radially limited and axially slidably connected to a crushing impeller 6. The transmission shaft 5 drives the crushing impeller 6 to rotate inside the water inlet pipe 4, which can crush large particles of impurities inside the sewage, avoiding the problem of large particles of impurities clogging the inside of the lifting shell 1, thereby improving the lifting efficiency of sewage and avoiding the problem of large particles of impurities colliding with the lifting impeller 3, resulting in severe wear and reduced service life, and the use effect is good;

[0025] Rotating frames 7 are fixed at both ends of the crushing impeller 6, and the top and bottom ends of the rotating frame 7 are rotatably connected with matching rollers 8. A fixing ring 9 is fixed inside the water inlet pipe 4, and guide protrusions 10 matching with two sets of matching rollers 8 are fixed on both sides of the fixing ring 9. When the crushing impeller 6 rotates, the crushing impeller 6 can also move axially back and forth, thereby improving the crushing effect of large-particle impurities, and the use effect is better;

[0026] A guide head 11 is fixed to one end of the transmission shaft 5, and the guide head 11 plays a role in guiding the water flow.

[0027] See also Figure 1A water outlet hole 13 is provided on the top of the lifting shell 1, and a water inlet hole 12 is provided at one end of the water inlet pipe 4. The water inlet hole 12 and the water outlet hole 13 are both connected to the external pipeline through a connecting flange, and the end faces of the water inlet hole 12 and the water outlet hole 13 are fixed with sealing gaskets. The utility model is provided with the above structure, in which the water inlet hole 12 and the water outlet hole 13 are respectively connected to each other through the external pipeline, thereby playing the role of lifting and transporting sewage.

[0028] See also Figure 1 and Figure 2 The lifting shell 1 and the water inlet pipe 4 are connected to each other by multiple groups of connecting bolts 15, and sealing rings are provided on the end faces of the lifting shell 1 and the water inlet pipe 4. By setting the above structure, the utility model can connect the water inlet pipe 4 and the lifting shell 1 tightly under the action of the multiple groups of connecting bolts 15, and it is easy to disassemble.

[0029] See also Figure 1 A base frame 14 is fixed to the bottom of the lifting shell 1, and a shock-absorbing rubber pad is fixed to the bottom of the base frame 14. The utility model sets the above structure, wherein the base frame 14 plays a supporting and fixing role for the lifting shell 1 as a whole, and the shock-absorbing rubber pad plays a shock-absorbing effect when the whole is working, thereby reducing the noise intensity during the overall use process.

[0030] The working principle of the utility model is: when in use, the external motor and one end of the rotating shaft 2 are connected to each other through a coupling, and then the output end of the external motor can drive the lifting impeller 3 to rotate inside the lifting housing 1 through the rotating shaft 2;

[0031] The external pipes are connected to the water inlet 12 and the water outlet 13 respectively, so as to enhance and transport the sewage.

[0032] The shaft 2 drives the lifting impeller 3 to rotate to transport and lift the sewage. The shaft 2 rotates and drives the transmission shaft 5 to rotate, and then the transmission shaft 5 drives the crushing impeller 6 to rotate inside the water inlet pipe 4, which can crush large particles of impurities inside the sewage and avoid the problem of large particles of impurities blocking the inside of the lifting shell 1, thereby improving the lifting efficiency of the sewage and avoiding the problem of large particles of impurities colliding with the lifting impeller 3, resulting in serious wear and shortening of its service life, and having a good use effect.

[0033] Furthermore, the crushing impeller 6 and the transmission shaft 5 are connected in a radial limited manner and in an axial sliding manner, that is, the transmission shaft 5 can drive the crushing impeller 6 to rotate without affecting the axial sliding of the crushing impeller 6 relative to the transmission shaft 5;

[0034] A rotating frame 7 is fixed at both ends of the crushing impeller 6, wherein the rotating frame 7 rotates synchronously with the crushing impeller 6, and the top and bottom of the rotating frame 7 are movably connected with a matching roller 8. Since guide protrusions 10 are fixed on both sides of the fixing ring 9, the matching roller 8 rotates with the crushing impeller 6, and the matching roller 8 can drive the crushing impeller 6 to reciprocate axially along the transmission shaft 5 during the rotation process under the limiting effect of the guide protrusions 10;

[0035] It can be seen from the above that while the crushing impeller 6 is rotating, the crushing impeller 6 can also perform axial reciprocating movement, thereby improving the crushing effect of large-particle impurities, and the use effect is better.
