AI Technical Summary

Technical Problem

In traditional UV absorber vacuum concentration devices, the single rotational motion of the stirring blades leads to significant local concentration differences, uneven mixing, and low heat transfer efficiency, which affects product quality and yield.

Method used

The stirring shaft is designed with multiple sets of horizontal and vertical blades. The up-and-down vibration and rotation of the stirring shaft are achieved by a motor-driven cam and spring mechanism. Combined with the synergistic effect of the horizontal and vertical blades, it breaks the limitations of traditional single rotation and realizes three-dimensional mixing of materials and uniform heat transfer.

Benefits of technology

It improves stirring efficiency, avoids uneven concentration in certain areas, shortens evaporation and concentration time, ensures product quality, avoids the risk of decomposition caused by local overheating, and improves heat exchange efficiency.

Abstract

The utility model relates to the technical field of vacuum concentration devices, and discloses an ultraviolet light absorber vacuum concentration device which comprises a vacuum evaporation tank, and a sealing cover covers the top end of the vacuum evaporation tank; the first motors are mounted on the front side and the rear side of the top of the sealing cover, second hinge lugs are connected to the outer ends of inserting rods, an assembling column is connected to the bottom end of the assembling table, stirring shafts are inserted into the assembling table and the assembling column, and horizontal blades are connected to the two sides of the exterior of each stirring shaft. And vertical blades are mounted at the positions, between the horizontal blades, on the two sides of the outer part of the stirring shaft. According to the vacuum concentration device for the ultraviolet light absorber, a cam is driven by a first motor to rotate, so that a cross arm, a second motor and an assembly table can be pushed to reciprocate up and down, a horizontal blade and a vertical blade vibrate up and down while rotating, and the limitation of traditional single rotary stirring is broken through; and the motion trails of the materials in the device are more complex and changeable.
