AI Technical Summary

Technical Problem

In existing sodium hydrosulfide concentration equipment, the decreased fluidity of the sodium hydrosulfide solution leads to channel blockage, affecting the stability and continuity of the concentration process.

Method used

An auxiliary mechanism works in conjunction with a drive mechanism to form an evaporation chamber by moving the extrusion assembly and the isolation section up and down and rotating. This helps the solution flow and scrapes off crystals, preventing channel blockage.

Benefits of technology

It effectively avoids channel blockage, ensures the stable and continuous operation of the concentration process, and improves evaporation efficiency and solution uniformity.

Abstract

This invention relates to the technical field of sodium hydrosulfide processing, specifically disclosing a sodium hydrosulfide concentration and purification equipment and production process, including an evaporator, with an auxiliary mechanism and a drive mechanism installed inside the evaporator; the auxiliary mechanism includes: an auxiliary frame that slides up and down and rotates within the evaporator, and a squeezing assembly connected to the drive mechanism and containing a portion of solution; the auxiliary frame includes: a connecting part and an isolation part, the isolation part being spaced apart from the inner wall of the evaporator and enclosing to form an evaporation chamber; after the drive mechanism is started, it drives the isolation part to move up and down and rotate synchronously through the squeezing assembly; when the isolation part moves downward, the solution in the squeezing assembly is discharged and enters the evaporation chamber below the isolation part; when it moves upward, the solution in the evaporation chamber flows back into the squeezing assembly; the sodium hydrosulfide concentration and purification equipment and production process of this invention have the effect of enabling the concentration process to proceed stably.
