Description

Technical Field

[0001] The utility model relates to the technical field of sewage lifting equipment, in particular to a fully automatic sewage lifting equipment. Background Art

[0002] With the rapid development of the economy and society, industrial and urban sewage treatment is directly related to the quality of life in a city. In order to centrally treat the generated sewage, sewage lifting equipment is needed.

[0003] For example, the authorization announcement number "CN207950889U" is named as a fully automatic sewage lifting equipment. Although the scraper pushes large-sized debris from the sewage outlet by scraping on the screen, improving the water purification effect and the working efficiency of the water pump, and uses the centrifugal force of the rotating shaft to retain small-sized impurities in the rotating shaft, resulting in cleaner water flow, on the one hand, reducing the pressure of the city's centralized sewage treatment system, and on the other hand, the treated water flow can be directly used, making people's lives more convenient. However, the screen is set inside the first water tank and is not easy to replace. If it is not replaced in time, the filtration quality of the sewage will be affected. At the same time, by starting the motor, the rotating shaft rotates, and the water flow is thrown into the secondary filter chamber under the action of centrifugal force. This will leave small particles of debris in the rotating shaft, which can easily cause the rotating shaft to clog. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-3 A fully automatic sewage lifting device includes a first water tank 1 and a second water tank 2. The upper surface of the first water tank 1 is connected to a water inlet pipe 3, and the surface of the water inlet pipe 3 is provided with a first solenoid valve 4. The front surface of the first water tank 1 is connected to a sewage outlet 5. The inner walls on both sides of the first water tank 1 are provided with first mounting blocks 6. The two first mounting blocks 6 serve to support a first filter screen 7. A first filter screen 7 is provided on the upper surfaces of the two first mounting blocks 6, and a scraping device is provided above the first filter screen 7. A mounting through hole 8 is provided on the rear surface of the first water tank 1, and the rear end of the first filter screen 7 extends into the mounting through hole 8. The first filter screen 7 can be extracted through the mounting through hole 8, which facilitates the replacement of the first filter screen 7 and ensures the filtration quality of the sewage.

[0019] The rear surface of the first water tank 1 is connected to a first pipe 9, which extends through the rear end of the second water tank 2. A first water pump 10 is installed on the surface of the first pipe 9 to pump water from the first water tank 1. The inner wall of the second water tank 2 is equipped with multiple second filters 11. The lower surface of the first pipe 9 is connected to multiple water distribution pipes 12, each corresponding to each of the second filters 11. These filters 11 filter small particles and prevent clogging of the first pipe 9. Each water distribution pipe 12 corresponds to a second filter 11. When a second filter 11 needs to be replaced, only the corresponding second filter 11 needs to be replaced. A second solenoid valve 13 is installed on each of the water distribution pipes 12. A second pipe 14 is connected to the lower surface of the second water tank 2. A second water pump 15 and a check valve 16 are installed on the surface of the second pipe 14 to prevent backflow of water. A first air vent 17 is installed on the upper surface of the first water tank 1 to ensure pressure balance within the first water tank 1. A second vent hole 18 is provided on the upper surface of the second water storage tank 2. The second vent hole 18 serves to ensure pressure balance in the second water storage tank 2.

[0020] The scraping device includes a cylinder 19, with a telescopic rod 20 disposed on the front surface of the cylinder 19. The front end of the telescopic rod 20 extends through the first water tank 1 and is provided with a connecting block 21. A plurality of limit blocks 22 are disposed above the connecting block 21. Each of the limit blocks 22 has a slide bar 23 disposed on its lower surface. The lower ends of the slide bars 23 slide through the connecting block 21 and are provided with a scraper 24. Each of the slide bars 23 is sleeved with a spring 25, the upper end of the spring 25 being connected to the lower surface of the limit block 22 and the lower end of the spring 25 being connected to the upper surface of the connecting block 21. Activating the cylinder 19 extends the telescopic rod 20, thereby driving the scraper 24 forward. Since the spring 25 is in a stretched state, the scraper 24 presses against the first filter screen 7, thereby scraping away large particles of debris on the first filter screen 7.

[0021] The scraper 24 is rotatably connected to the slide bar 23. Since the scraper 24 is rotatably connected to the slide bar 23, the scraper 24 and the first filter screen 7 can be always in plane-to-plane contact, so that the scraping is more thorough.

[0022] A fixing block 26 is provided at the rear end of the first filter screen 7, and a plurality of bolts 27 are provided at the rear end of the fixing block 26. One end of each of the plurality of bolts 27 passes through the fixing block 26 and is threadedly connected to the first water storage tank 1. By screwing the bolts 27, the first filter screen 7 can be fixed more firmly.

[0023] A plurality of second mounting blocks 28 are provided on the inner wall of the second water storage tank 2, corresponding one to the second filter screen 11. Each of the plurality of second mounting blocks 28 has a water outlet hole 29 on its lower surface, and the second filter screen 11 is disposed within the second mounting blocks 28. This facilitates installation and removal of the second filter screen 11; simply open the upper cover of the second water storage tank 2 and remove the second filter screen 11.

[0024] The first mounting block 6 and the first filter screen 7 are both arranged to tilt upward from front to back. Large particles of impurities will roll into the sewage outlet 5 along the tilted surface, greatly improving the filtering efficiency.

[0025] Working principle: First, open the first solenoid valve 4, and the sewage enters the first water tank 1 through the water inlet pipe 3, and then passes through the first filter screen 7 to filter out large particles of impurities. Then start the first water pump 10, and the preliminarily filtered sewage is pumped into the first pipe 9. Open the second solenoid valve 13, and enter the second filter screen 11 through each water distribution pipe 12. The preliminarily filtered sewage is filtered again to filter out smaller particles. Then start the second water pump 15, and enter the urban sewage treatment pipe through the second pipe 14 to complete the automatic lifting of sewage.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
