Explosion-proof scale cleaning tool for wave guide tube of radar liquid level gauge of floating-roof oil tank

Abstract

The invention discloses an explosion-proof scale cleaning tool for a wave guide tube of a radar liquid level gauge of a floating-roof oil tank, and belongs to the technical field of a cleaning tool for a wave guide tube of a radar liquid level gauge of a storage tank. The explosion-proof scale cleaning tool comprises a rotating scale cleaning part, an extension rod part, an operating platform part and an operating handle part, wherein one end of the extension rod of the extension rod part is connected with the rotating scale cleaning part, and the other end of the extension rod of the extension rod part penetrates through the operating platform part to extend out of the wave guide tube to be connected with the operating handle part; the rotating scale cleaning part comprises a rotating center rod; a plurality of connecting supports are hinged on the peripheral surface of the rotating center rod; a spring is arranged between each of the connecting supports and the rotating center rod; and a scraping plate is hinged to the outer end of each of the connecting supports. The explosion-proof scale cleaning tool for the wave guide tube of the radar liquid level gauge of the floating-roof oil tank, oil stain in the wave guide tube of the radar liquid level gauge is effectively cleaned, and the data reading accuracy of the radar liquid level gauge is ensured.

Description

technical field [0001] The invention relates to a scale cleaning tool for waveguide tubes of radar liquid level gauges of storage tanks, and belongs to the technical field of scale cleaning of waveguide tubes of radar level gauges of storage tanks. Background technique [0002] With the development of petrochemical pipelines, more and more crude oil is imported, and high-viscosity crude oil is gradually increasing. The radar level gauge used on large oil storage tanks is due to the phenomenon of high-viscosity crude oil hanging on the wall of the waveguide, which will cause scaling on the inner wall of the waveguide over time, so that the data of the radar level gauge stagnates at this level data. location, especially for oil storage tanks with operations, dynamic monitoring cannot be implemented. At present, the method of hanging a copper hammer on a pull rope is used to swing back and forth at the position where the scale may be formed. The accuracy of cleaning the scale ...

The radar level gauge used on large oil storage tanks is due to the phenomenon of high-viscosity crude oil hanging on the wall of the waveguide, which will cause scaling on the inner wall of the waveguide over time, so that the data of the radar level gauge stagnates at this level data. location, especially for oil storage tanks with operations, dynamic monitoring cannot be implemented

At present, the method of hanging a copper hammer on a pull rope is used to swing back and forth at the position where scaling may occur. The accuracy of cleaning the scale is low, the operation time is long, and the cleaning effect is not good.
