Chemical Reactor Agitator Blade

Product Specifications

Technical details and manufacturing context for Chemical Reactor Agitator Blade

Definition

A precision-engineered mechanical component designed for installation on agitator shafts within chemical reactors. It provides the primary mixing action by rotating through chemical solutions, ensuring homogeneous blending, heat transfer, and reaction efficiency. These blades are critical for maintaining consistent process conditions in batch and continuous chemical manufacturing. They are manufactured to withstand corrosive environments and mechanical stresses. Available in stainless steel 316L, Hastelloy C-276, and titanium alloy, these blades are suited for demanding chemical service. Key parameters include an overall blade diameter of 800–2000 mm, blade thickness of 8–20 mm, hub bore diameter of 50–120 mm, and 3–6 blades per assembly. The pitch angle ranges from 30–45 degrees, and the maximum speed is 150–300 rpm. Operating pressure is 1.0–1.6 MPa, and operating temperature ranges from -40 to 200°C. Surface finish is Ra 0.8–1.6 μm, balancing grade is G6.3 (ISO 1940), and weight ranges from 50–200 kg. Material grade for stainless steel is 316L per ASTM A240. These blades are designed for use in basic chemical manufacturing, where they ensure efficient mixing and heat transfer. They are typically mounted on a shaft and rotate to create fluid movement, promoting uniform distribution of reactants and temperature. The blades are engineered to minimize vibration and provide reliable performance under corrosive conditions. For specific applications, it is essential to verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges. Proper selection depends on reactor size, process requirements, and material compatibility. Regular inspection and maintenance are necessary to ensure optimal performance and longevity.

Working Principle

The agitator blade is mounted on a rotating shaft inside a chemical reactor. As the shaft rotates, the blade moves through the liquid, creating fluid flow and turbulence. This motion promotes mixing, heat transfer, and chemical reaction by ensuring uniform distribution of reactants and temperature. The blade's pitch angle and speed determine the intensity of mixing and shear forces. The blade is designed to operate within specified pressure and temperature ranges, and its material is chosen for corrosion resistance. The rotation creates a vortex or flow pattern that enhances blending and prevents stagnation. The blade's geometry and number of blades influence the mixing efficiency and power consumption. Proper installation and alignment are critical to avoid vibration and premature wear.
