A lot of equipment buyers are choosingtitanium stirrerIt is easy to encounter specification matching problems.improper selection, There will be insufficient motor power, stirring load belt will not move, or excessive configuration margin result in waste of procurement and operating cost.Based on Baoji China titanium valley project practical experience, Combing three-step selection method, Reference parameters are given according to reactor volume classification, simultaneously organizing materials, Key Points of Shaft Seal Selection and Procurement Inquiry List, Convenience Chemical, medicine, Quick reference for buyers in the hydrometallurgy industry.
Complete selection is divided into three steps, first confirm the actual effective volume of the reactor, the unit is cubic meters;The second step is to clarify the viscosity of the material medium and distinguish between low, medium and high viscosity intervals;Step 3 Determine blade form in combination with viscosity, Then select the blade diameter according to the kettle volume, diameter of axle, Motor power and speed reference range.
Low viscosity medium suitable viscosity ≤100 mPa·s, Common media include water, Various dilute solutions, Low viscosity liquid with good fluidity.1 m ³ reactor, blade diameter Φ 300 mm, shaft diameter Φ 40 mm, motor power 0.75 ‑ 1.5kW, operating speed 100 ‑ 200 rpm;5m³ Reactor blade diameter Φ500mm, shaft diameter Φ60mm, motor power 2.2‑4kW, speed 80‑150rpm;10m³ Reactor blade diameter Φ700mm, shaft diameter Φ80mm, motor power 4‑7.5kW, speed 60‑120rpm;50m³ Reactor blade diameter Φ1100mm, shaft diameter Φ100mm, motor power 11‑18.5kW, speed 50‑100rpm.The three-blade propeller is preferred in this working condition, which has simple structure, high mixing and conveying efficiency and low shear strength.
Medium viscosity medium suitable viscosity range 100‑1000 mPa·s, suitable for oils, syrup, medium concentration slurry.1 m ³ Reactor blade diameter Φ 350 mm, shaft diameter Φ 50 mm, motor power 1.5 ‑ 3 kW, speed 60 ‑ 120 rpm;5m³ Reactor blade diameter Φ600mm, shaft diameter Φ70mm, motor power 4‑7.5kW, speed 50‑100rpm;10m³ Reactor blade diameter Φ800mm, shaft diameter Φ90mm, motor power 7.5‑15kW, speed 40‑80rpm;50m³ Reactor blade diameter Φ1300mm, shaft diameter Φ120mm, motor power 18.5‑30kW, speed 30‑60rpm.Six blade straight turbine propellers are recommended for stable material mixing and moderate shear force.
High viscosity medium viscosity ≥1000 mPa·s, mostly used for high concentration slurry, paste, polymer materials.1 m ³ Reactor blade diameter Φ 400 mm, shaft diameter Φ 60 mm, motor power 3 ‑ 5.5kW, speed 30 ‑ 60 rpm;5m³ Reactor blade diameter Φ700mm, shaft diameter Φ80mm, motor power 7.5‑15kW, speed 20‑50rpm;10m³ Reactor blade diameter Φ900mm, shaft diameter Φ100mm, motor power 15‑22kW, speed 15‑40rpm;50m³ Reactor blade diameter Φ1500mm, shaft diameter Φ140mm, motor power 30‑45kW, speed 10‑30rpm.Anchor or frame blades are preferred. The blades are close to the wall of the kettle, and the wall scraping and heat transfer performance are good.
Material needs to match corrosion conditions: dilute sulfuric acid, chloride, seawater conditions TA2 or TA10;N6 pure nickel is selected for high concentration strong alkali working condition;304/316L stainless steel can be selected for neutral weak corrosion conditions;Medicine and electronics have requirements for material purity, and TA1 pure titanium or N4 pure nickel is selected.
There are three types of shaft seal options: mechanical seal versatility, sealing effect is good, adapt to most conditions;Packing seal procurement cost is more friendly, suitable for low pressure and low speed conditions;Magnetic seal can achieve no leakage, adapt to strong corrosion, flammable and explosive production scenarios, procurement costs will rise to a certain extent.
When ordering from suppliers, Eight key messages are recommended for identification, reactor volume, Medium type and viscosity, operating temperature, work stress, Required blade pattern, Material designation, Shaft seal type, Whether explosion proof configuration is required.
Agitator selection configuration is too large, later can downshift use? Not recommended.Large configuration not only consumes excess power continuously, Excessive shear force will also change the material process state, It is more economical to select matching specifications according to working conditions.
How to distinguish between propulsion and turboprop? Low viscosity material selection propulsion type, material axial circulation ability;For medium viscosity, turbine type is selected, and radial shear mixing effect is better.Anchor and frame blades are preferred for high viscosity materials.
titanium stirrerCompare stainless steel procurement cost differences? titanium stirrerThe initial purchase cost is about 3‑5 times that of stainless steel, However, the service life can reach 5 - 15 years, Stainless steel is mostly 1‑3 years, Accounting for five-year cycle comprehensive use costs, Titanium can be reduced by 30‑50%.
How to determine the agitator speed? Low viscosity material ≤ 100 mPa·s, speed setting 100 ‑ 200 rpm;medium viscosity 50‑100rpm;High viscosity material control speed ≤50rpm.
