Description

Technical Field

[0001] This utility model relates to the field of chemical reaction apparatus, specifically to a safe chemical laboratory reaction apparatus. Background Technology

[0002] A chemical laboratory safety reaction device is a specially designed device to ensure the safe conduct of chemical experiments. By operating from outside the sealed reaction apparatus, it solves the safety hazards faced by experimenters when handling chemical experiments involving violently reacting or corrosive liquids. Chinese patent (authorization announcement number CN 215540884U) discloses a chemical laboratory safety reaction device that places the violently reacting process within a sealed space. It utilizes a hand-cranked wheel outside the reaction components to drive a robotic arm and stirring rod, replacing the need for experimenters to directly stir the mixture in the reaction container. This solves the safety problems associated with experiments involving violently reacting or corrosive liquids. Adjusting the dripping component allows for control of the dripping rate of the reaction solution according to experimental needs, reducing errors from manual intervention. However, this design requires waiting for the liquid in the dripping component to drain completely or removing the component and replacing it with a new one when adding reagents, which is inconvenient and affects the experimental reaction results. Therefore, those skilled in the art have provided a chemical laboratory safety reaction device to solve the problems mentioned in the background art. Utility Model Content
