Mixing device for polymer gel raw material production

Abstract

The invention discloses a mixing device for polymer gel raw material production. The device comprises a mixing barrel, wherein a fixed ring is fixed at the upper end of the mixing barrel; a turntableslides at the upper end of the fixed ring; first rotating shafts are mounted on two sides of the turntable; the upper ends of the first rotating shafts are in key connection with an outer gear; the outer side of the outer gear is engaged with an inner gear; the inner gear is embedded in the fixed ring; first stirring blades are welded on the first rotating shafts; a mounting base is fixed at the upper end of the fixed ring; a servo motor is fixedly connected to the upper end of the mounting base; a second rotating shaft is fixed to an output shaft of the servo motor; second stirring blades arewelded to the upper side and the lower side of the second rotating shaft; an inner wall wiping mechanism is fixedly connected to the middle part of the second rotating shaft; a feeding pipe communicates with the upper end of the mixing barrel; and discharging pipes symmetrically communicate with the lower end of the mixing barrel. The stirring directions of the stirring blades in the mixing barrel are different, so different vortexes are generated; and thus, the mixing speed of raw materials is increased, mixing quality is good, working efficiency is high, and the wall of the barrel can be automatically cleaned.

Description

technical field [0001] The invention belongs to the technical field of mixing devices, and in particular relates to a mixing device for the production of polymer gel raw materials. Background technique [0002] Polymer gel is a system composed of a three-dimensional network or interpenetrating network formed by cross-linking and polymerization of molecular chains and a solvent (usually water), which is similar to biological tissue. The cross-linked structure makes it insoluble and maintains a certain shape, and the existence of osmotic pressure makes it swell to achieve volume balance. This kind of polymer gel can be produced due to different solvent types, salt concentration, pH, temperature, and different electrical stimulation and light radiation. Volume change, sometimes phase transition occurs, the mesh size increases, the network loses elasticity, the gel phase region no longer exists, and the volume swells sharply, and this change is reversible and non-connected.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a mixing device for the production of polymer gel raw materials, to solve the above-mentioned background technology that the stirring rod itself cannot rotate, and the two stirring rods can only rotate along the inner wall of the mixing drum under the drive of the driving motor. To achieve stirring, it can only be stirred in one direction, the mixing is not uniform, and the stirring range of the stirring rod at the center of the mixing drum cannot be reached, the mixing effect is poor, and the work efficiency is low; If it is not cleaned in time, the emulsion will dry and solidify on the inner wall of the mixing drum, which will cause troublesome cleaning in the future, and it will accumulate more and more after a long time, which will affect the normal use of the device
