Description

Technical Field

[0001] The invention relates to the technical field of municipal drainage pipeline maintenance, and in particular to an inverted siphon automatic flushing structure and a flushing method thereof. Background Art

[0002] Drainage facilities like inverted siphons and sewage wells are prone to siltation due to solid waste deposition and sludge accumulation. Traditional dredging methods (such as single high-pressure water jets, bamboo splinters, or steel cables) are inefficient, have short-term effects, and struggle to effectively stir and remove the accumulated sludge at the bottom, leading to recurring siltation. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic flushing structure for an inverted siphon and a flushing method thereof.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: an inverted siphon automatic flushing structure, including an inlet well and an outlet well, an inverted siphon is arranged between the water inlet well and the outlet well, an air intake pump and a water pump are arranged on one side of the water inlet well, the connecting pipes of the air intake pump and the water pump both enter the inverted siphon, and a diversion baffle is arranged on the outlet well.

[0005] It is further configured that the connecting pipe of the air intake pump is retractable.

[0006] It is further configured as follows: the guide baffle is installed in front of the water outlet of the sewage well, and the top height of the guide baffle is higher than the top of the water outlet.

[0007] The present invention also discloses a method for automatically flushing an inverted siphon structure, comprising the following steps: S1: Install the air pump and water pump, place the diversion baffle in the target sewage well, and block the water inlet of the front section of the inverted siphon; S2: Start the water pump to fill the lower part of the inverted siphon with water, and then start the air intake pump to inject high-pressure air into the silted inverted siphon to break up and loosen the silt, and continue to extend it; S3: The diversion baffle forces the water to rise on its rear side and overflow from the top, forming a circulation in the well, continuously stirring the sludge at the bottom to prevent siltation; S4: Recover the connecting pipes of the air intake pump and the water pump, retain the guide baffle, and complete the flushing.

[0008] It is further configured that: the air intake pump outputs compressed gas.

[0009] It is further configured that the pressure of the compressed gas is between 1-1.8 MPa.

[0010] In summary, the present invention has the following beneficial effects: 1. Integrated and efficient: air-water pulse loosening and baffle circulation anti-siltation work together to form a dredging-anti-siltation closed loop. 2. Thorough dredging: The combination of air-water pulse physical crushing has a good effect on removing deep and stubborn sediments. 3. Effective anti-siltation: The diversion-type circulation efficiency-enhancing baffle actively stirs the sludge through forced circulation flow, fundamentally reducing the siltation of the inverted siphon and the bottom of the well. 4. Long-lasting effect: The stirring effect of the continuous operation of the system after dredging significantly reduces the probability of re-siltation in the short term. 5. Practical structure: The baffle structure is simple, reliable and easy to install. 6. When the sewage lift pump is started, the water level at the inverted siphon outlet is lowered, and the connecting pipes of the air intake pump and the water pump are recovered to form a height difference. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of an inverted siphon automatic flushing structure. DETAILED DESCRIPTION

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] An inverted siphon automatic flushing structure comprises an inlet well and an outlet well, wherein an inverted siphon is arranged between the inlet well and the outlet well, wherein one end of the inverted siphon is a water inlet, and one side of the outlet well is a water outlet.

[0014] A diversion baffle is installed in the outlet well. Installed in front of the sewage well outlet, its top is 30cm higher than the outlet top, acting as a physical barrier. This baffle provides flow blocking and diversion, circulation disturbance, sludge agitation, anti-silting, and coordinated dredging.

[0015] An air intake pump and a water pump are provided on one side of the water inlet well. Both the air intake pump and the water pump are provided with connecting pipes, and the connecting pipe on the air intake pump is a retractable structure.

[0016] The pressure of the compressed gas output by the air intake pump is between 1-1.8 MPa.

[0017] A method for automatically flushing an inverted siphon structure comprises the following steps: S1: Install the air pump and water pump, place the diversion baffle in the target sewage well, and block the water inlet of the front section of the inverted siphon; S2: Start the water pump to partially fill the bottom of the inverted siphon with water, then start the air intake pump to inject air into the silted inverted siphon to break up and loosen the silt, and continue to extend the airflow to slowly cover the inverted siphon; S3: In the above process, the diversion baffle forces the water to rise on its rear side and overflow from the top, forming a circulation in the well and continuously stirring the sludge at the bottom; S4: Recover the connecting pipes of the air intake pump and the water pump, retain the diversion baffle, and complete the flushing. That is, after the automatic flushing of this application is completed, the diversion baffle will be retained. In the subsequent process, when the sewage lifting pump is started, the water level at the outlet of the inverted siphon will be lowered to form a height difference, which can increase the sewage discharge flow rate. The sewage lifting pump is an original component that can pump sewage from the pump room. Of course, after the flushing is completed, the plug that blocks the water inlet of the front section of the inverted siphon in S1 will be removed, so that the sewage pumped by the sewage lifting pump can flow smoothly.

[0018] The working principle of this application is as follows: first, water is injected into the target pipe (such as the water inlet of the siphon) through the water pump's connecting pipe. After ensuring a certain amount of water flows out of the siphon's outlet, the air intake pump is activated and continuously flushes the siphon. The impact of the high-pressure airflow and the water flow can instantly break up and loosen blockages (such as agglomerated sludge and entangled objects). Furthermore, because the air intake pump's connecting pipe is retractable, it can continuously flush deep into the siphon.

[0019] Then, the setting of the diversion baffle can prevent the main stream of sewage from rushing directly to the outlet, forcing it to form a local water level rise behind the baffle.

[0020] The raised sewage needs to overflow from the top of the baffle to be discharged. This overflow process forms a continuous backflow zone in front of the baffle, generating a strong underwater circulation flow.

[0021] This circulating flow can effectively suck up and stir the accumulated sludge at the bottom of the sewage well, keeping it in suspension, greatly reducing the risk of sludge accumulation in the inverted siphon.

[0022] Therefore, during the dredging operation, this circulating flow can continuously stir the loose materials flushed into the well by the gas-water pulse, preventing them from settling again, and allowing them to be efficiently sucked away by the subsequent sewage pump or flow out on their own after the diversion baffle is removed, significantly improving the overall dredging efficiency and durability of the effect.

[0023] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
