Description

Technical Field

[0001] This utility model relates to the field of underground drainage technology, and in particular to a drainage device. Background Technology

[0002] In wastewater treatment processes, it is common practice to bury odor ducts underground to collect and transport odorous gases (such as ammonia, hydrogen sulfide, methane, and formaldehyde) from the wastewater. Water often accumulates inside these ducts, requiring extraction to meet subsequent odor treatment needs. Current methods involve digging deep wells at predetermined locations within the ducts, equipped with suction pumps, level gauges, and flow meters. The suction pump removes the water. To prevent odor leakage, these wells are typically sealed, making inspection and maintenance of the equipment extremely difficult. Furthermore, deep well construction is complex and involves a large workload, and the volume of water in a typical duct is relatively small, resulting in numerous drawbacks.

[0003] Therefore, there is an urgent need to design a hydrophobic device to overcome the shortcomings of one or more of the existing technologies mentioned above. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a hydrophobic device, characterized in that it includes: a vertical pipe, the vertical pipe being located below the ground, a liquid level gauge being provided inside the vertical pipe for detecting the liquid level height inside the vertical pipe, the vertical pipe also being provided with a self-priming hydrophobic pump, the hydrophobic pump being used to pump the liquid inside the vertical pipe, the hydrophobic pump being connected to the liquid level gauge, and the bottom end of the vertical pipe being connected to an external main pipe through a water guide pipe.

[0005] In a preferred embodiment, the bottom end of the vertical pipe is also provided with a negative pressure connecting pipe, the other end of which is connected to an external main pipe and has a check valve function to balance the pressure inside the vertical pipe.

[0006] In a preferred embodiment, a shallow well is provided on the ground, and the vertical pipe is located in the shallow well, the depth of which is 1m-1.5m.

[0007] In a preferred embodiment, the positional difference between the bottom end of the vertical pipe and the bottom wall of the main pipe is greater than or equal to 1m.

[0008] In a preferred embodiment, the negative pressure connecting pipe is also connected to a one-way valve.

[0009] The beneficial effects of this utility model are: by setting up a shallow well and placing both the drainage pump and the level gauge in the shallow well, the amount of engineering work is smaller compared to the traditional deep well method, and since the shallow well is on the ground, maintenance is more convenient, faster and safer.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1 As shown, a hydrophobic device is provided, characterized in that it includes: a vertical pipe 11 located below ground level, a liquid level gauge 13 installed inside the vertical pipe 11 for detecting the liquid level height inside the vertical pipe 11, a self-priming hydrophobic pump 14 installed inside the vertical pipe 11 for pumping liquid from the vertical pipe 11, and a negative pressure connecting pipe 15 installed at the bottom end of the vertical pipe 11, the other end of which is connected to an external main pipe 10 for balancing the pressure inside the vertical pipe 11;

[0019] Specifically, to address the problems of large engineering workload and inconvenient maintenance associated with traditional deep well drilling, this application proposes a shallow well 16 drilled on the ground, preferably with a depth of 1m. A vertical pipe 11 is installed at the bottom of the shallow well 16, with its bottom end located 1m below the external main pipe 10. The bottom end of the vertical pipe 11 is connected to the main pipe 10 via a water guide pipe 12, allowing water accumulated in the main pipe 10 to flow into the vertical pipe 11. To facilitate the extraction of water, a [further details are needed]. A self-priming condensate pump 14 is provided to pump out the accumulated water in the riser pipe 11, thereby reducing the water level and preventing it from affecting subsequent odor treatment processes. A level gauge 13 is also installed in the riser pipe 11 to measure the water level. Due to the consistent air pressure, the water level in the riser pipe 11 reflects the water level in the main pipe 10. The self-priming condensate pump 14 is electrically connected to the level gauge 13, and the level gauge 13 sends the measurement information to the control system. When the liquid level reaches a predetermined value, a signal is sent to the control system, which then controls the self-priming condensate pump 14 to start and pump out the accumulated water. When the liquid level falls below the predetermined value, the self-priming condensate pump 14 stops working. Since the self-priming condensate pump 14 pumps out accumulated water, a pressure difference may occur between the vertical pipe 11 and the main pipe 10, causing the liquid level in the vertical pipe 11 to not accurately reflect the liquid level in the main pipe 10. To avoid this, a negative pressure connecting pipe 15 can be provided in the vertical pipe 11. This negative pressure connecting pipe 15 is connected to the main pipe 10. By connecting the main pipe 10 and the vertical pipe 11, the pressure difference between the vertical pipe 11 and the main pipe 10 is balanced, thereby ensuring that the liquid level in the vertical pipe 11 accurately reflects the liquid level in the main pipe 10. Preferably, a one-way valve can also be installed in the negative pressure connecting pipe 15, allowing air from the main pipe 10 to enter the vertical pipe 11 through the negative pressure connecting pipe 15, but preventing backflow of air from the vertical pipe 11 through the one-way valve.

[0020] The negative pressure connecting pipe 15 is inclined upward to avoid the liquid blocking the flow of gas.

[0021] To prevent odor from overflowing from the riser pipe 11, the top of the riser pipe 11 is sealed after the level gauge 13 and the self-priming condensate pump 14 are installed.

[0022] It should be noted that the depth values ​​mentioned above can be increased or decreased according to actual needs.

[0023] In summary, by setting up a shallow well 16 and installing both the drainage pump 14 and the level gauge 13 in the shallow well 16, this application involves less engineering work compared to the traditional deep well method. Furthermore, since the shallow well 16 is on the ground, maintenance is more convenient, faster, and safer.

[0024] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
