[0024] See 1~ Fig. 5 As shown, this is an embodiment of the present invention, and the provided superimposed vacuum pump station will be described in detail below:

[0025] A type of superimposed vacuum pump station, such as Figs. 1-5 As shown in the figure, the system includes: a mounting base 1; uprights 2 symmetrically fixedly connected to the top of the mounting base 1; a vacuum tank 3 fixedly mounted on the top of both uprights 2; two sewage pumps 4 fixedly mounted on the top of the mounting base 1, located on opposite sides of the top of the mounting base 1; rubber shock-absorbing pads 5 installed at the connection points between the two sewage pumps 4 and the mounting base 1, the rubber shock-absorbing pads 5 being fitted onto the bolts mounting the sewage pumps 4; and connecting pipes 6 fixedly connected to the air inlet ends of the two sewage pumps 4, with the end of connecting pipe 6 furthest from the sewage pumps 4 connected to the vacuum tank 3. Ball valve 7 is installed in the middle of each of the two sewage pumps 4. Soft-seal check valves 8 are fixedly connected to the outlet ends of the two soft-seal check valves 8. Ball valve 9 is fixedly connected to the end of the two soft-seal check valves 8 away from the sewage pumps 4. The ends of the two ball valves 9 away from the soft-seal check valves 8 are connected to a common sewage pipe 10. A flange 11 is installed at the end of the sewage pipe 10 away from the ball valve 9. A dry claw vacuum pump 12 is fixedly installed in the middle of the top of the mounting base 1. A connecting pipe 13 is fixedly connected to the input end of the dry claw vacuum pump 12. The end of the connecting pipe 13 away from the dry claw vacuum pump 12 is connected to the vacuum tank 3.

[0026] Further, as shown in Figs. 1-5 The control cabinet 14 is fixedly installed on one side of the vacuum tank 3. The sewage inlet 15 and the sewage outlet 16 are symmetrically arranged on the vacuum tank 3 away from the control cabinet 14. The dust filter 17 is fixedly connected to the top of the vacuum tank 3. The output end of the dust filter 17 is fixedly connected to the vacuum filter one 18. The vacuum filter one 18 is connected to the vacuum tank 3. The vacuum filter two 19 is fixedly connected to the top of the vacuum tank 3. The dry vane vacuum pump 20 is fixedly installed on one side of the vacuum tank 3 close to the dry vane vacuum pump 20. The end of the vacuum filter two 19 away from the vacuum tank 3 is fixedly connected to the dry vane vacuum pump 20. The vacuum pressure gauge 21 is fixedly installed on the top of the vacuum tank 3.

[0027] In combination with the above-mentioned embodiments, the following is the working process and working principle of the above-mentioned embodiments:

[0028] The initial state is:

[0029] The ball valve one 7 is in an open state. The ball valve two 9 is in an open state. The sewage pipe 10, the sewage inlet 15 and the sewage outlet 16 are respectively connected to the corresponding pipelines.

[0030] The working state is:

[0031] After the dry claw vacuum pump 12, the sewage inlet 15 and the sewage outlet 16 are connected to the corresponding pipelines, the dry claw vacuum pump 12 and the dry vane vacuum pump 20 are started. At the same time, a stable vacuum source is provided for the vacuum tank 3. The air inside the vacuum tank 3 is extracted through the connecting pipe one 6, thereby forming a negative pressure. The sewage enters the vacuum tank 3 through the sewage inlet 15. Then, the two sewage pumps 4 are started. The sewage extracted by the sewage pump 4 is discharged through the soft sealing check valve 8, the ball valve two 9 and the sewage pipe 10. When the dry vane vacuum pump 20 continuously operates, the air in the vacuum tank 3 will be filtered by the dust filter 17, the vacuum filter one 18 and the vacuum filter two 19, and then extracted by the dry vane vacuum pump 20, thereby avoiding the sewage from entering the dry vane vacuum pump 20. In this process, the vibration generated by the sewage pump 4 is buffered by the rubber damping pad 5 at the bottom of the two stands 2, thereby reducing the vibration of the whole stacked vacuum pump station, further reducing the noise of the stacked vacuum pump station during operation, and under the action of the symmetrical arrangement of the two stands 2 and the compact installation of each structure on the installation base 1 and the stand 2, not only can the gravity distribution of the stacked vacuum pump station be more stable, further reducing the vibration, but also can save the space occupied by the stacked vacuum pump station. Under the compact layout, the pipeline structures such as the connecting pipe one 6, the sewage pipe 10 and the connecting pipe two 13 are shorter than the management length in the traditional sewage pump, reducing the impact and vibration generated by the long pipeline and the fluid flowing in the pipeline, further reducing the vibration and improving the service life of the pipeline.

[0032] The above merely illustrates the embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
