Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage discharge technology, specifically to a negative pressure sewage purification and discharge equipment. Background Technology
[0002] Negative pressure sewage discharge equipment is a system that uses the principle of negative pressure to collect and treat sewage. It is designed to improve sewage collection efficiency and reduce environmental pollution. Negative pressure sewage discharge equipment can be used for urban domestic sewage discharge as well as rural sewage discharge.
[0003] Existing negative pressure sewage discharge equipment is generally buried in a pre-designated soil pit. It mainly includes water supply pipelines, intercepting wells, and negative pressure collection wells. The intercepting wells collect domestic sewage discharged by each household, and then transport the sewage to the negative pressure collection wells through pipelines. The negative pressure collection wells are installed in locations that facilitate centralized collection of sewage and are responsible for transporting the sewage to the city's centralized sewage pipeline. However, it still has shortcomings in actual use. In areas with low temperatures in winter, the sewage inside the negative pressure collection well is prone to freezing when it is stagnant, which makes it impossible for the negative pressure pipeline to discharge the sewage in the negative pressure well in a timely manner. Utility Model Content
[0004] The purpose of this invention is to provide a negative pressure sewage purification and discharge device to address the aforementioned shortcomings in the technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model provides, for example Figure 1 - Figure 5 The negative pressure sewage purification and discharge equipment shown includes an intercepting well 3 and a negative pressure collecting well 9. A connecting pipe 8 connects the intercepting well 3 and the negative pressure collecting well 9. A sewage inlet pipe 2 and a feeding pipe 10 are connected to the side wall of the intercepting well 3. A negative pressure discharge pipe 15 is connected to one side of the negative pressure collecting well 9. An exhaust pipe 14 is provided on the outer wall of the negative pressure discharge pipe 15. A vacuum pump 12 is connected to the end of the exhaust pipe 14. A sealing cover 11 is provided on the top of the negative pressure collecting well 9. A controller 17 is provided on the top of the sealing cover 11. A hose 22 is connected to the bottom of the controller 17. A floating ball 20 is connected to the end of the hose 22. A fixing block 25 is fixed inside the floating ball 20. A vibration motor 26 is fixed on the top of the fixing block 25. The vibration motor 26 is connected to the controller 17 through a cable. A suspension rod 21 is connected to the bottom of the fixing block 25.
[0024] The floating ball 20 includes two hemispherical shells, and the end faces of the two hemispherical shells are glued together.
[0025] A solenoid valve 13 is connected to the end of the exhaust pipe 14, and a valve 16 is connected to the end of the negative pressure sewage pipe 15; during the process of the negative pressure sewage pipe 15 discharging sewage, the valve 16 is in the open state.
[0026] In this embodiment, it should be noted that the extension end of the feeding pipe 10 is connected to a resident's home. A funnel and a faucet can be connected to the extension end of the feeding pipe 10. By adding flocculant to the funnel and letting water flow from the faucet into the funnel, the flocculant is flushed into the intercepting well 3. Domestic sewage enters the intercepting well 3 through the sewage inlet pipe 2. The flocculant can purify the sewage.
[0027] As the sewage enters through the connecting pipe 8, one end of the negative pressure sewage pipe 15 is inserted downward into the negative pressure collection well 9. After the sewage overflows the end of the negative pressure sewage pipe 15, the solenoid valve 13 is activated, the exhaust pipe 14 is in the open state, and then the vacuum pump 12 is activated. The vacuum pump 12 extracts the air in the negative pressure sewage pipe 15. The air is discharged after passing through the exhaust pipe 14. Under the negative pressure state inside the negative pressure sewage pipe 15, the pressure inside the negative pressure collection well 9 is high, thereby forcing the sewage into the negative pressure sewage pipe 15. Under the action of pressure, the sewage can continuously pass through the negative pressure sewage pipe 15 and be discharged outward.
[0028] In a low-temperature environment, the controller 17 is activated and the vibration motor 26 is powered on. The vibration motor 26 generates vibration during operation, which is transmitted to the floating ball 20 and the fixed block 25, thereby transmitting the vibration to the suspension rod 21. The suspension rod 21 and the floating ball 20 can move the sewage, thus keeping the sewage in a dynamic state. Therefore, the sewage will not freeze inside the negative pressure collection well 9, which is conducive to the sewage being discharged from the negative pressure drain pipe 15.
[0029] like Figure 1 - Figure 5 As shown, a valve plate 18 is installed inside the intercepting well 3 near the connecting pipe 8. A threaded rod is installed on the top of the valve plate 18. A top cover 1 is installed on the top of the intercepting well 3. A threaded seat 7 is fixed on the top of the top cover 1. The threaded rod is threadedly engaged with the threaded seat 7. A handle 6 is connected to the top of the threaded rod. It should be noted that when a large amount of sewage accumulates in the intercepting well 3, the user can manually turn the handle 6 counterclockwise from the outside of the intercepting well 3. The handle 6 drives the threaded rod to rotate. The bottom end of the threaded rod is connected to the top of the valve plate 18 through a shaft. When the threaded rod rotates, the valve plate 18 does not rotate. At the same time, the threaded rod rotates on the threaded seat 7 and moves upward, thereby driving the valve plate 18 to move upward, thereby opening the end of the connecting pipe 8, and releasing the sewage in the intercepting well 3 into the negative pressure collection well 9.
[0030] like Figure 1 - Figure 5 As shown, filter screens 19 are installed inside the intercepting well 3 near the ends of the sewage inlet pipe 2 and the feed pipe 10. A connecting plate 24 is connected to the top of the filter screen 19. The end of the connecting plate 24 extends upward and penetrates to the outside of the top cover 1. A clamping plate 23 is fixed to the top of the top cover 1. The top of the connecting plate 24 and the end of the clamping plate 23 are both provided with clamping grooves, and the two clamping grooves are engaged with each other. It should be noted that during the process of sewage entering the intercepting well 3 through the sewage inlet pipe 2, the filter screen 19 blocks impurities in the sewage, which can prevent impurities from accumulating in the intercepting well 3 and prevent sewage and impurities from entering the connecting pipe 8 at the same time, ensuring that the sewage flows smoothly through the connecting pipe 8.
[0031] like Figure 1 - Figure 5As shown, an overflow pipe 5 is fixed to the top of the top cover 1, and a well cover 4 is also provided on the top of the top cover 1. The bottom end of the overflow pipe 5 extends into the interior of the intercepting well 3.
[0032] It should be noted that when sewage enters the intercepting well 3, if impurities in the sewage clog the connecting pipe 8, a large amount of sewage will be concentrated in the intercepting well 3 and discharged from the overflow pipe 5, thereby preventing the intercepting well 3 from being squeezed and deformed by the sewage.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
