Description

TECHNICAL FIELD

[0001] The utility model relates to the field of glass lined pressure vessel inspection, especially to a glass lined pressure vessel inspection device. BACKGROUND

[0002] Glass lined pressure vessels can adapt to the corrosion of strong acids such as hydrochloric acid and sulfuric acid and various organic solvents, and are widely used in chemical, food, pharmaceutical and other industries. According to the national standard, glass lined pressure vessels must be periodically inspected by inspection agencies, and the quality of the glass lining determines the service life of the glass lined pressure vessel. The standard stipulates that the periodic inspection items of glass lined pressure vessels mainly include visual inspection of glass lining, direct current high voltage detection of glass lining and thickness measurement of glass lining. Among them, visual inspection mainly observes whether the repaired part of the glass lining has corrosion, cracking and falling off phenomenon; the direct current high voltage inspection of the glass lining detects defects and weak points in the glass lining through the light and / or sound signals emitted by the spark discharge and high voltage generator at the same time.

[0003] Because glass lined pressure vessels contain toxic, harmful, flammable and explosive media, inspectors cannot directly enter the interior of the pressure vessel for inspection, so it is necessary to use an oxygen and explosion detector to detect toxic and harmful substances and oxygen content before inspection. The visual inspection of the interior of the glass lined pressure vessel requires that the entire metal surface of the pressure vessel be smooth and clean; the glass lining thickness measurement uses a handheld precision glass lining coating thickness gauge; and the glass lining electric spark detection mainly contacts the container inner surface with the brush of the tester, so that the high voltage current passes through the surface of the equipment to observe whether there is a leakage phenomenon. During periodic inspection, the existing inspection process has the following shortcomings:

[0004] 1) The inspector generally holds the direct current electric spark tester handle and the precision glass lining coating thickness gauge into the pressure interior at the manhole to scan the glass lining, but the electric spark tester handle is short and the precision glass lining coating thickness gauge can only be held by hand, which cannot scan the glass lining at the bottom of the glass lined pressure vessel, resulting in missed defects;

[0005] 2) The inspector usually holds a flashlight for visual inspection when performing internal macroscopic inspection of the pressure vessel, but due to the deep and long space of the pressure vessel, it is not possible to effectively visually inspect the surface condition of the glass lining at close range;

[0006] 3) When the glass lining thickness gauge measures the thickness, the inspector can only hold the device to measure the thickness of the glass lining near the manhole without entering the interior of the pressure vessel, resulting in missed defects;

[0007] 4) If there are materials attached to the inner surface of the pressure vessel, the inspector also needs to use a brush to extend into the container to remove the coating, scale, chemical contaminants or other substances on the surface of the container;

[0008] 5), the test flow needs to frequently take many test tools, and the test tool function is single and cannot realize simultaneous test of multiple aspects, which reduces the work efficiency of the test personnel. Utility model content

Inspectors can use the telescopic rod 1 to insert the enamel coating thickness gauge 31 and the DC high-voltage detection probe and brush 4 into any part of the enamel-lined pressure vessel for scanning, solving the problem of missed detections caused by the short handle of existing spark testers and the fact that precision enamel coating thickness gauges can only be held by hand.
