Abstract

The invention discloses a liquid level meter auxiliary structure suitable for a harsh work environment. The liquid level meter auxiliary structure comprises an outer cylinder, an outer flushing ring used for cleaning the outer cylinder, an inner cylinder used for containing a liquid level meter, and an inner flushing ring used for cleaning the inner cylinder and driving the inner cylinder to rotate. The outer flushing ring is located at the outer portion of the outer cylinder and is fixedly arranged. The flushing end of the outer flushing ring is arranged by facing the outer cylinder, and theinner cylinder is arranged in the outer cylinder. The inner cylinder is rotationally connected with the outer cylinder. The inner flushing ring is located between the inner cylinder and the outer cylinder and is fixedly arranged. The flushing end of the inner flushing ring is arranged by facing the inner cylinder. A stirring blade is arranged at the bottom end portion of the inner cylinder, and the stirring blade and the inner cylinder are fixedly connected to rotate synchronously. By means of the liquid level meter auxiliary structure, the problem of liquid level measuring under the special medium environment in the industry field can be solved, the measuring precision is ensured, the equipment failure rate is lowered, and the device can be free of maintenance.

Description

technical field

[0001] The invention relates to the technical field of liquid level gauges, in particular to an auxiliary structure for liquid level gauges suitable for harsh working environments. Background technique

[0002] The float level gauge is composed of a float, a plunger, etc. Its working principle is designed according to the principle of Archimedes buoyancy. When the liquid level of the container changes, the float also moves up and down. Due to the magnetic effect, the reed switch of the float level gauge is magnetically attracted, so that the sensor The internal resistance changes linearly, and then the converter converts this resistance change into a 4mA~20mA standard DC signal output to realize long-distance detection and control of the liquid level.

[0003] In the actual measurement project, because the float level gauge is a contact measurement method, it is greatly affected by the working environment. For example, when the measured medium has volatile ...
