AI Technical Summary
In existing technologies, the absorption process of concentrated sulfuric acid relies on manual control, which is prone to splashing due to uneven operating force, unstable movements or fatigue. Furthermore, there is a lack of effective mechanisms to prevent backflow or accidental release, posing safety hazards.
A concentrated sulfuric acid detection and aspiration device is adopted, which utilizes a servo motor to drive a threaded transmission and a friction self-locking mechanism to achieve reliable self-locking and precise control of the solution. The manual process is simplified by operating the device with a button or knob, and solution spillage is avoided.
It significantly reduces the skill level required for operation, avoids solution backflow, rebound and splashing caused by human error or accidental contact, ensures the safety of operators and the environment, and improves the ease and accuracy of operation.
