Abstract

In order to solve the problem that the liquid level detection of high-viscosity fluids is difficult in the prior art, the invention provides a high-viscosity fluid-oriented reusable liquid level detection head. The high-viscosity fluid-oriented reusable liquid level detection head comprises an interlayer vertical pipe, a detection assembly arranged in the interlayer vertical pipe, and a pneumatic-electric converter connected with the output ends of detection pipes, wherein the interlayer vertical pipe comprises an inner sleeve and an outer sleeve coaxial with the inner sleeve; an airtight space is formed between the inner sleeve and the outer sleeve; the outer sleeve is connected with a heat supply device to ensure that a thermal medium output by the heat supply device is communicated witha space formed between the inner sleeve and the outer sleeve; the detection assembly comprises two detection pipes which are arranged between the inner sleeve and the outer sleeve; and the two detection pipes and the outer sleeve form a high detection port and a low detection port. During the measurement, the high-viscosity fluids entering the detection pipes are continuously heated so that the high-viscosity fluids cannot be attached to the inner side walls of the detection pipes, thereby realizing repeated using.

Description

technical field [0001] The invention relates to the field of petrochemical tank truck loading, in particular to a reusable liquid level detection head for liquid level detection for high-viscosity fluids. Background technique [0002] At present, in the field of high-viscosity liquid level detection such as crude oil, asphalt, and liquid sulfur in the modern petrochemical industry, especially when tankers are filled with high-viscosity fluids such as crude oil, asphalt, and liquid sulfur, it is still impossible to achieve due to the conditions of the loading site. Automatic detection, during the loading process, the switch of the valve is controlled by manual visual inspection of the liquid level. [0003] At the same time, due to the characteristics of the above-mentioned high-viscosity fluid, after a general liquid level detection device is used once, it will be adhered by the high-viscosity fluid and cannot be used again, resulting in high cost.
