Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 An integrated sewage lifting device includes a collection tank 1, a processor, and a lifting mechanism. The top of the collection tank 1 is sealed with two inlet pipes 2. A first crushing shell 3 is welded to the top between the two inlet pipes 2. A sewage pipe 6 is sealed to one side of the first crushing shell 3. A first motor 4 is fixed to the top of the first crushing shell 3 by bolts. The output end of the first motor 4 is fixed to a first rotating shaft by bolts. Multiple first crushing blades 5 are fixed to the outer wall of the first rotating shaft by bolts. The first crushing blades 5 are located inside the first crushing shell 3. Driven by the first motor 4, the first crushing blades 5 rotate, thereby initially crushing the impurities in the sewage.

[0024] The bottom end of the liquid inlet pipe 2 is welded with a second crushing shell 9. The second crushing shell 9 is provided with multiple filter holes 10. Sewage flows into the water collection tank 1 through the filter holes 10. Two second motors 11 are fixed to the bottom outer wall of the water collection tank 1 by bolts. The output end of the second motor 11 is fixed to a second rotating shaft by bolts. Multiple second crushing blades 12 are fixed to the outer wall of the second rotating shaft by bolts. The second crushing blades 12 are located inside the second crushing shell 9. Driven by the second motors 11, the second crushing blades 12 rotate, thereby crushing the impurities in the sewage again.

[0025] A valve 7 is installed on the sewage pipe 6, and a one-way valve 8 is installed on the liquid inlet pipe 2. The first crushing shell 3 has a cylindrical structure, and the second crushing shell 9 has a spherical structure. A scraper 13 is fixed to the outer wall of the second rotating shaft by bolts. The scraper 13 scrapes on the inner wall of the second crushing shell 9. The scraper 13 is made to scrape on the inner wall of the second crushing shell 9 by the second motor 11, thereby scraping off the impurities on the inner wall of the second crushing shell 9, thus preventing impurities from clogging the filter holes 10.

[0026] The lifting mechanism includes a sewage lifting pump 17. A support frame 16 is bolted to one side of the outer wall of the collection tank 1. The sewage lifting pump 17 is bolted to the top of the support frame 16. The inlet end of the sewage lifting pump 17 is connected to a connecting pipe 14 via a flange. The outlet end of the sewage lifting pump 17 is connected to a sewage discharge pipe 18 via a flange. The other end of the connecting pipe 14 is connected to a solenoid valve 15 via a flange. The other end of the solenoid valve 15 is connected to the second crushing housing 9. Under the action of the sewage lifting pump 17, sewage and crushed impurities are input into the connecting pipe 14 through the solenoid valve 15, and then discharged into the sewage network pipe from the sewage discharge pipe 18.

[0027] A liquid level sensor 20 is inserted into the top of the water collection tank 1. The processor, the first motor 4, the second motor 11, the solenoid valve 15, and the liquid level sensor 20 monitor the water level in the water collection tank 1 through the liquid level sensor 20. The model of the liquid level sensor 20 is TP2403. An exhaust pipe 19 is sealed and inserted into the top of the water collection tank 1.

[0028] The working principle of this embodiment is as follows: When in use, the power is turned on, valve 7 is opened, and sewage enters the first crushing housing 3 through sewage pipe 6. Then, the first motor 4 is started, and the first crushing blade 5 rotates under the drive of the first motor 4, thus initially crushing the impurities in the sewage. Next, the sewage, carrying the crushed impurities, is input into the second crushing housing 9 through the liquid inlet pipe 2. Then, the second motor 11 is started, and the second crushing blade 12 rotates under the drive of the second motor 11, thus further crushing the impurities in the sewage. Simultaneously, the scraper 13 is moved by the second motor 11 to the second crushing housing 9. The inner wall is scraped, thereby scraping off the impurities on the inner wall of the second crushing shell 9, thus preventing the impurities from clogging the filter hole 10. Then, the sewage flows into the water collection tank 1 from the filter hole 10. During the crushing process, the water level in the water collection tank 1 is monitored by the liquid level sensor 20. When the water level in the water collection tank 1 reaches the set value, the information is transmitted to the processor for processing. Then, the processor controls the solenoid valve 15 to open and starts the sewage lift pump 17. Under the action of the sewage lift pump 17, the sewage and crushed impurities are input into the connecting pipe 14 through the solenoid valve 15, and then discharged into the sewage network pipe from the sewage pipe 18.
