SOLINAS

This project involves the design and development of a compact, innovative, and portable agitator mechanism tailored for homogenizing solid materials or waste with liquid in tanks with depths ranging from 1 meter to 5 meters. The core focus is on functionality, ease of use, and operational safety in challenging environments, such as sludge storage tanks. Key Features: Extendable Shaft Mechanism: Uses a lead screw and telescopic shafts to extend from 1 meter (retracted) to 5 meters (fully extended) in 100 rotations. The impeller activates only after reaching the desired depth, protecting the tank walls. Portability and Compact Design: The device is lightweight (~25kg) and compact (fits into a 1.5m x 0.5m box). Designed for ease of transportation and operation. User-Friendly Interface: Includes a central console with a depth set button, rotation toggle, and display for monitoring depth and RPM. Enables even inexperienced operators to use the device safely. Material and Durability: Built with aluminum alloys to reduce weight and ensure durability. Centrifugal retractable blades provide efficient mixing and can be replaced easily if damaged. Waterproofing and Safety: Electrical components are isolated from liquid-prone areas, ensuring spark-proof and waterproof operation. Anti-vibration mounts, sealed joints, and wear-resistant coatings enhance reliability. Efficiency and Customization: The design accommodates various impeller types for different slurry tank configurations. Simulation and analysis, including CFD and FEA, confirm the system's effectiveness and safety. Application: Ideal for industries requiring efficient mixing in deep, narrow tanks, such as sewage processing, waste treatment, and chemical industries. This innovative approach ensures safety, efficiency, and adaptability, solving real-world challenges in slurry mixing and waste homogenization. Components: 1. Central Console 2. Central bearing 3.
