Siphon blade type phosphoric acid extractor

Abstract

The invention discloses a siphon blade type phosphoric acid extractor which comprises a motor (1), a rotating shaft (2), a working chamber (3), a feed port (4) and a discharge port (5), wherein the motor (1) and the working chamber (3) are connected through the rotating shaft; the feed port (4) is positioned on the side surface of the working chamber (3); the discharge port (5) is positioned on the top of the working cavity (3); a stator A (8) and a multistage stator B (10) are fixed in the working chamber (3); the rotating shaft in the working chamber (3) is fixedly provided with a rotor A (10) and a multistage rotor B (11); and the end surfaces of the multistage stator B (10) and the multistage rotor B (11) are provided with a plurality of rows of annularly distributed teeth. The invention is characterized in that the end surface of the stator A (8) is annularly and uniformly distributed with one row of skewed teeth, and the rotor A (9) is a siphon blade. The invention improves the through capacity of the material, enhances the shearing, crushing and mixing actions on the material, and enhances the mass transfer efficiency of the device.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a siphon blade type phosphoric acid extractor. Background technique [0002] At present, the extraction process of phosphoric acid is mainly realized by an emulsifier. As an extraction and mass transfer equipment, the emulsifier mainly realizes the extraction of phosphoric acid through the shear force generated by the mutual rotation of the multi-layer stator and the rotor. Patent 200910220309 discloses an emulsifying machine, a fixed gear is installed inside the cavity, and the moving gear driven by the motor shaft, the fixed gear and the moving gear are multi-stage and intermesh, and the rectangular teeth of the moving gear and the rectangular teeth of the fixed gear are inserted within the gap between adjacent rows of the other side. The rectangular teeth of the moving gear and the fixed gear are straight teeth, which have shear force, but the material passing capacity is l...

AI Technical Summary

Problems solved by technology

The rectangular teeth of the moving gear and the fixed gear are straight teeth, which have shear force, but the material passing capacity is limited; and because the tooth shape design is mostly straight teeth, pulse phenomenon is prone to occur during the rotational movement of the stator and the rotor

The generation of pulse phenomenon is likely to cause adverse effects such as increased vibration during equipment operation and unstable equipment operation.
