When selecting a center-driven single-pipe sludge suction machine, the key factors are tank diameter, sludge characteristics, and budget. Here are specific suggestions:
I. Matching Core Parameters
Tank Diameter and Depth
Tank Diameter: Typically φ35m to φ40m, customizable to meet specific needs.
Tank Depth: Generally 5.5m, with an effective water depth of 4.5m at the tank edge.
Sludge Characteristics
Activated Sludge: Ensure the variable cross-section design of the suction pipe matches the sludge distribution at the tank bottom.
Inert Sludge: Strengthen the scraper design to prevent sludge accumulation.
II. Selection Considerations
Drive Unit
Torque: The larger the tank diameter, the higher the torque requirement; a reducer with torque protection should be selected.
Sealing Performance: Under harsh operating conditions, sealing performance directly affects equipment durability.
Sludge Discharge Method
Siphon Sludge Discharge: Utilizes a vacuum pump to create a secondary siphon for sludge removal; suitable for applications with adjustable flow rates. Static pressure sludge removal: Sludge is removed based on the water level difference between the inside and outside of the tank, suitable for applications with high sludge concentrations.
III. Application Scenarios
Wastewater Treatment Plants
Suitable for circular sedimentation tanks with diameters of 15-60 meters, especially suitable for process layouts with peripheral influent and peripheral effluent.
Industrial Wastewater Treatment
Widely used in chemical, textile, and metallurgical industries to treat wastewater containing suspended solids.
Sludge Thickening
Can be used in thickening tanks to reduce sludge volume, creating conditions for subsequent dewatering treatment.
IV. Precautions
Ordering Instructions
Specify the tank diameter, depth, design flow rate, reflux ratio, and other key technical parameters, and provide civil engineering drawings of the sedimentation tank.
Specify the equipment material. If accessories such as inlet column pipes, baffle skirts, stainless steel effluent troughs, effluent weirs, scum baffles, and sleeve valves are required, please specify the relevant dimensions.
Special Requirements
If the user has special requirements, please specify them in the order contract.
