The operational efficiency of sewage tank dredging robots is mainly determined by the model configuration, sewage tank volume, and the viscosity of sediment (such as soft mud, compacted mud, and impurities). The core efficiency performance and reference of mainstream models are as follows:
1、 Core homework efficiency indicators
-Light duty models (suitable for small sewage tanks/emergency dredging): The hourly dredging volume is about 5-15 cubic meters, suitable for sewage tanks with a capacity of 50-200 cubic meters and a sedimentation rate of ≤ 40% (such as small pre-treatment tanks in factories), and can simultaneously complete sludge suction and preliminary solid-liquid separation.
-Medium sized models (suitable for conventional sewage tanks in municipal/industrial parks): The hourly dredging capacity is 15-35 cubic meters. For sewage tanks with a volume of 200-800 cubic meters and a small amount of floating impurities (such as plastic and fiber), with high-pressure flushing function, it can quickly loosen the sludge and suction it.
-Heavy duty models (suitable for large industrial sewage tanks/high concentration sedimentation scenarios): The hourly dredging volume is 35-80 cubic meters, and the processing capacity is 800-3000 cubic meters. The sedimentation material is compacted mud (hardness ≤ 4MPa) or sewage tanks containing sand and gravel. Some models are equipped with crushing cutters, which can efficiently handle stubborn sedimentation.
2、 Key efficiency influencing factors
1. Suction and processing capacity: Models equipped with high negative pressure vacuum pumps (negative pressure value -0.08~-0.098MPa) can quickly suction thick sludge (moisture content 85% -95%) and reduce pipeline blockage; Models with built-in filters (aperture 5-20mm) or cutters can synchronously separate impurities, avoiding shutdown cleaning, and increasing efficiency by 30% -50% compared to ordinary models.
2. Environmental adaptability: Models with waterproof rating of IP68 and track type walking (climbing angle ≤ 35 °) can directly operate in sewage tanks with a water depth of ≤ 2m without the need for advance pumping (traditional pumping requires 40% of the total construction period), reducing single tank operation time by 35% -55%; The explosion-proof model (Ex d IIB T4 Gb) is compatible with chemical wastewater tanks to avoid efficiency interruptions caused by safety risks.
3. Automation and Collaboration: Models equipped with AI visual positioning (identifying dead corners of sedimentation) and remote control can accurately clean areas that are difficult to reach manually, such as corners of the pool bottom and pipe openings, reducing 20% -30% of repetitive operations; Heavy duty models that support multi machine collaboration (1 main dredging machine+1 auxiliary conveying machine) can increase efficiency by an additional 40% for ultra large sewage tanks.
3、 Typical scenario efficiency reference
-Small factory sewage tank (with a capacity of 150 cubic meters, silted up as soft mud): Light robots can complete dredging and tank wall flushing in 8-12 hours.
-Municipal medium-sized sewage regulating tank (with a capacity of 500 cubic meters and a small amount of fiber impurities): A medium-sized robot can complete dredging and temporary storage of sludge in 15-20 hours.
-Large scale chemical wastewater tank (with a capacity of 2000 cubic meters, compacted mud+sand and gravel): Heavy duty robots (with knives) can complete the entire tank dredging in 30-45 hours, while also meeting environmental discharge standards (reducing sludge moisture content to below 80%).
