AI Technical Summary

Technical Problem

When facing continuous liquid level measurement of high-temperature volatile alkali liquid circulation tank, the existing blow-type liquid level meter has a complex structure and high cost, and is prone to liquid return due to weak steam pressure, damage to the differential pressure transmitter, and may reduce measurement accuracy due to crystallization blockage and increase maintenance costs.

Method used

A purge blowing level meter structure assembly is designed, using the first and second connecting pipes arranged in parallel, and the air circulation is controlled by a purge solenoid valve, the pressure reducing valve reduces the air pressure, the differential pressure transmitter detects the water level height, and the opening and closing of the solenoid valve is controlled by a timer to realize the cleaning of impurities in the pipeline and the liquid level measurement.

Benefits of technology

The liquid level gauge structure is simplified, space occupancy and maintenance costs are reduced, pipeline blockage and liquid return, ensuring measurement accuracy and safety of differential pressure transmitters.

Abstract

The utility model belongs to the field of detection, and provides a purging type gas blowing liquid level meter structure assembly, which comprises a water tank for storing a water level to be measured; the first connecting pipeline is provided with an air inlet and an air outlet, the air inlet is used for introducing compressed air, the end part, close to the air outlet, of the first connecting pipeline extends into the water tank, the first connecting pipeline is provided with a purging electromagnetic valve, and the purging electromagnetic valve is used for controlling opening or closing of air circulation in the first connecting pipeline; and the second connecting pipeline and the first connecting pipeline are arranged in parallel. Compared with the prior art, the liquid level meter has the advantages that the overall structure of the liquid level meter is simplified, the maintenance cost is reduced, pipeline crystals can be removed after the purging electromagnetic valve is opened, the pipeline is prevented from being blocked, meanwhile, the pressure value of inflow compressed air can be reduced in advance through the pressure reducing valve, and the service life of the liquid level meter is prolonged. The phenomenon that the liquid level meter is damaged due to liquid backflow is avoided, and the accuracy of the pressure value measured by the differential pressure transmitter is guaranteed.
