Description

Technical Field

[0002] In chemical production processes involving alcohol, it is necessary to monitor the concentration of alcohol raw materials or intermediate alcohol solutions online in real time to keep track of each stage of production.

[0003] Currently, multi-tank alcohol concentration detection typically requires a separate alcohol meter to be installed in each tank, resulting in high equipment costs, complex maintenance, and large space requirements. Some integrated detection devices also suffer from problems such as probe contamination, low measurement accuracy, and inability to dynamically switch detection targets. This invention solves these technical pain points by enabling the reuse of a single probe across multiple tanks through a track-driven structure.

[0004] Therefore, we propose a multi-point alcohol concentration monitoring device based on track drive. Summary of the Invention

Valves are provided on both the main pipe and the branch pipes. The guide rail is positioned above the tanks and extends horizontally along the tank arrangement direction. Both ends of the slider are equipped with pulleys that can move within the guide rail. A drive motor is mounted on the slider to provide power for the rotation of the pulleys. A stepper motor is mounted on one side of the drive motor, and the output shaft of the stepper motor is connected to a lead screw. A fixing frame is provided at the other end of the lead screw, and a lifting block is sleeved on the outside of the lead screw. The alcohol concentration meter is mounted on one end of the lifting block. The alcohol concentration meter is connected to the conduit, which is connected to the probe. The probe is placed inside the tank.
