Description

Technical Field

[0001] This utility model belongs to the field of water treatment engineering technology, specifically relating to an auxiliary treatment system for floating sludge on the surface of sedimentation tanks. Background Technology

[0002] With the acceleration of industrialization and urbanization, wastewater discharge is increasing daily, making wastewater treatment a crucial link in environmental protection and sustainable development. Sedimentation tanks, as an important component of the wastewater treatment process, play an indispensable role in solid-liquid separation. They utilize the principle of gravity settling to allow suspended solids in the wastewater to settle to the bottom, thus achieving preliminary wastewater purification. Among numerous wastewater treatment processes, sedimentation tanks are widely used in wastewater treatment plants of various sizes and industrial wastewater treatment facilities, playing a vital role in ensuring effluent quality.

[0003] Due to the high dissolved oxygen content, the activated sludge in the front-end aeration tank often floats to the surface with the air bubbles, forming a sludge layer. Although existing technologies use physical water spraying to break up the air bubbles and promote sludge settling, this reliance on manual operation has significant drawbacks: manual water spraying requires continuous manpower, is labor-intensive, and has inconsistent efficiency, especially in large-scale wastewater treatment scenarios where labor costs surge. Furthermore, traditional sedimentation tank designs do not consider the long-term maintenance needs of the effluent outlet; the adhesion of algae and other organisms easily clogs the outlet, requiring regular manual cleaning, further increasing operation and maintenance costs and safety risks.

[0004] In summary, this utility model proposes an auxiliary treatment system for floating sludge on the surface of sedimentation tanks to at least partially solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Please see Figure 1 and Figure 2 This embodiment provides an auxiliary system for treating surface sludge in a sedimentation tank, serving as a system for removing sedimented sludge and treating surface sludge in sedimentation tank 200. The system includes a rotary scraper, a circulating spraying mechanism, and a control terminal. The rotary spraying mechanism includes a visual recognition sensor, a vacuum suction tank 300, a high-pressure water pump 400, and a rotary nozzle 500, and is located at the top of the rotary scraper body 100. The visual recognition sensor, vacuum suction tank 300, high-pressure water pump 400, and rotary nozzle 500 of the rotary scraper body 100 and the rotary spraying mechanism are all electrically connected to the control terminal. When the rotary scraper body 100 rotates, a camera identifies the surface sludge residue after scraping the bottom of the sedimentation tank 200, and transmits the identified sludge residue data to the control terminal. The control terminal then controls the rotary nozzle 500 to spray the residual sludge. This system effectively solves the problem of high costs associated with manual sludge treatment, improves the sludge treatment efficiency of the sedimentation tank 200, and reduces labor costs and maintenance difficulty.

[0018] Based on the above scheme, in this sedimentation tank surface sludge auxiliary treatment system, the control terminal controls the rotary scraper body 100 and the circulating spray mechanism to work together. Its vacuum suction tank 300 includes an inlet pipe 301 and an outlet pipe. The inlet pipe 301 extends into the sedimentation tank 200, and the outlet pipe is connected to the input end of the high-pressure water pump 400. The output end of the high-pressure water pump 400 is connected to the rotary nozzle 500. The control terminal controls the vacuum suction tank 300 to draw water from the sedimentation tank 200 into the vacuum tank through the inlet pipe 301, and controls the water in the vacuum tank to be transmitted to the input end of the high-pressure water pump 400 through the outlet pipe. Simultaneously, the control terminal receives sludge residue data identified by a visual recognition sensor, controls the direction of the rotary nozzle 500, and controls the output end of the high-pressure water pump 400 to deliver water to the rotary nozzle 500 for spraying.

[0019] Specifically, the surface sludge auxiliary treatment system of this sedimentation tank enables the coordinated operation of the rotary scraper body 100 and the circulating spray mechanism through the control terminal. Its vacuum suction tank 300 draws water from the sedimentation tank 200 through the inlet pipe 301 and delivers the water to the high-pressure water pump 400 through the outlet pipe. The high-pressure water pump 400 then drives the rotary nozzle 500. The control terminal, combined with the sludge residue detected by the visual recognition sensor, precisely controls the spray direction of the rotary nozzle 500 and the water delivery operation of the high-pressure water pump 400, forming a closed-loop treatment process of "identification and positioning - water suction and pressurization - directional spraying". This achieves intelligent and efficient cleaning of sludge, and has the dual advantages of water resource recycling and precise operation.

[0020] In addition, its rotating nozzle 500 includes a rotating high-pressure nozzle 501 and at least one set of rotating water jet nozzles 502. The rotating high-pressure nozzle 501 and the rotating water jet nozzles 502 are connected to the high-pressure water pump 400. The rotating high-pressure nozzle 501 is located above the top edge of the sedimentation tank 200, and the rotating water jet nozzles 502 are located above the liquid surface 201 inside the top of the sedimentation tank 200. Specifically, the four edges of the top of the sedimentation tank 200 are set as water outlets, so the rotating high-pressure nozzle 501 is used to flush and clean the water outlets. This is mainly because long-term operation of the water outlets can easily lead to the growth of moss, algae and other organisms, which can easily clog the water outlets.

[0021] Furthermore, a sludge recovery port is located inside the sedimentation tank 200 near the outlet. A rotating water jet nozzle 502 breaks up air bubbles carrying sludge, while simultaneously driving some non-settling sludge to the recovery port. A multi-angle synergistic cleaning mechanism is formed by the high-pressure water pump 400, which works in conjunction with the rotating high-pressure nozzle 501 and the rotating water jet nozzle 502. The former, installed above the top edge of the sedimentation tank 200, directionally flushes the outlet, removing attached organisms and impurities to ensure smooth water flow. The latter, positioned above the liquid surface 201 within the tank near the sludge recovery port, breaks up air bubbles and drives sludge to the recovery port for centralized treatment. This dual function of edge flushing and surface driving prevents outlet blockage and efficiently collects sludge, improving system cleaning efficiency and reliability.

[0022] It should be noted that the rotary high-pressure nozzle 501 is a thickened, adjustable direct-injection high-pressure nozzle with a height of 50mm and an external thread of 20mm. This high-pressure configuration serves two purposes: first, it meets the requirements for structural strength and durability. The thickened shell can resist corrosion from the sedimentation tank's 200-ton water, sludge erosion, and wear caused by long-term high-pressure water jetting, extending its service life. The 50mm height ensures that the internal flow channel can withstand 10-20MPa high pressure, avoiding stress concentration. The 20mm external thread (1 / 2 inch, DN15) is compatible with standard water pipe interfaces, preventing stripping and facilitating installation and maintenance. Second, it enables adjustable spray patterns. By rotating the head adjustment component, it can switch between direct-injection and fan-shaped modes, and can dynamically adjust the spray angle and water flow pattern based on feedback from a visual recognition sensor, accurately handling floating sludge in different scenarios and avoiding water waste. The core of this design lies in balancing structural reliability and functional flexibility. Thickening and standard interfaces enhance durability and adaptability, while adjustable direct injection enables precise handling of complex floating sludge scenarios, ensuring long-term stable and efficient system operation.

[0023] In this embodiment, the visual recognition sensor consists of an infrared / visible high-definition binocular camera, a visible light LED strip, an infrared LED strip, and a luminous ruler. This sensor integrates multispectral imaging, active illumination, and spatial positioning technologies to achieve accurate all-weather, three-dimensional identification and positioning of 200 cubic meters of floating sludge in the sedimentation tank. The infrared / visible high-definition binocular camera, combined with a dual-light source system, captures the color and texture of the floating sludge during the day using the visible light channel and penetrates interference at night using the infrared channel. The binocular stereo vision, combined with the luminous ruler, achieves high-precision positioning with an error ≤5mm. During operation, the sensor simultaneously acquires dual-spectral images, extracts features, and calibrates the distance, transmitting data such as the location and area of ​​the floating sludge to the control terminal in real time to drive the nozzle for directional operation. It possesses advantages such as anti-reflective properties, adaptive supplemental lighting, and stable coordinate reference, with a response speed ≥10 frames / second. It is widely applicable to wastewater treatment, industrial sedimentation, drinking water treatment, and other scenarios, providing precise and intelligent visual support for sludge cleaning.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
