Phosphorus tank top-mounted anti-adhesion liquid level meter

Abstract

The invention provides a phosphorus tank top-mounted anti-adhesion liquidometer and relates to the technical field of phosphorus chemical industry. The liquidometer sequentially comprises a detectionmechanism, a mounting and guiding mechanism and a liquidometer body from bottom to top, wherein the detection mechanism is arranged between the mounting and guiding mechanism and the liquidometer body; or an automatic or manual traction device for moving the detection mechanism up and down is arranged on the liquid level meter body; the turning plate type liquid level meter solves common problemsof an existing turning plate type liquid level meter, traction operation of the floating ball rod (2) can be conveniently conducted, impurities and dirt on the floating ball rod are effectively removed, constraint of hardening of a phosphorus sludge layer on the floating ball rod can be conveniently eliminated, and the turning plate type liquid level meter is accurate in measurement and higher inprecision; in addition, the traction device is simple in structure, the production process of an original liquid level meter is slightly changed, cost is low, and equipment can be rapidly updated andupgraded.

Description

Technical field [0001] The present invention relates to the field of phosphorus chemical techniques, and more particularly to a phosphor trough top level level gauge. Background technique [0002] Electric heating method produces yellow phosphorus to heat a certain proportion of sintered phosphorus, silica and coke in the electric furnace, so that the phosphorus element in the phosphorite is subjected to a gas, and after removing dust such as dust removal, it is washed with cooling water. Gas gives liquid yellow phosphorus. The refining, storage and transportation of liquid yellow phosphorus is achieved by a variety of different specifications of storage tanks. Because Huang Phosphorus has the characteristics of self-combustion, highly toxic, etc., which is determined by the state as a major risk source, and is the focus of production enterprises and safety supervision Monitoring objects, the accuracy and real-time status of its data are important parameters to determine the secu...

AI Technical Summary

Problems solved by technology

[0004] ①The surface of the float rod on the liquid level gauge is easy to adhere to the elemental phosphorus and other impurities after the phosphorus vapor condenses, causing blockage, affecting the movement of the float rod with the change of liquid level, and causing inaccurate measurement; at the same time, the elemental phosphorus attached to the surface Burning corrosion will occur, shortening the service life of the liquid level gauge

[0005] ②The muddy phosphorus layer in the yellow phosphorus storage tank will harden after a long time of accumulation, causing the float rod of the liquid level gauge to be fixed, making it impossible to measure the liquid level accurately

[0006] For example, "A method and device for measuring the liquid level of yellow phosphorus in a storage tank 201510558829.8, a self-cleaning yellow phosphorus interface liquid level gauge 201120134123.6, a yellow phosphorus liquid level measuring device 201521024753.2" and other schemes, these schemes have the problem of large errors, Moreover, yellow phosphorus is easily attached to the guide rod of the liquid level gauge, causing burning damage. In addition, these measurement methods can only measure fixed-point timing values, and cannot guarantee continuous measurement; the most important problem is that when the mud phosphorus layer is compacted, the current A liquid level gauge with a structure cannot rely on itself to break away from the shackles of the mud phosphorus layer, and must rely on auxiliary equipment, which is labor-intensive and is not conducive to real-time monitoring and alarm of the phosphorus tank liquid level
