Embodiment 1

[0019] Pour out the oil samples in the 6 oil sample glass bottles filled with gear oil, put them upside down for 30 minutes, put them in the muffle furnace, first take 35 minutes to rise to 265°C, then take 25 minutes to rise to 560°C, and maintain for 15 minutes , Close the muffle furnace and take out the six oil sample glass bottles. Observed with the naked eye, there is no residual oil, coke or impurities. The oil stains in it have been volatilized and the bottles are not deformed. They can be used directly for subsequent use.

Embodiment 2

[0021] After inverting the oil-like glass bottle containing the residual oil for 30 minutes, put it into the muffle furnace to raise the temperature to 270°C for 30 minutes, then raise the temperature to 575°C for 22 minutes, and maintain it for 13 minutes, then turn off the muffle furnace to cool down naturally Finally, take out the oil sample glass bottle and observe with the naked eye. There is no residual oil, coke or impurities. The oil in it has been volatilized. The bottle is clean and transparent without deformation, and can be used directly for subsequent use.

Embodiment 3

[0023] Invert the oil-like glass bottle containing the hydraulic oil contaminated by cinders and sludge for 30 minutes, put it into the muffle furnace to raise the temperature to 275°C for 40 minutes, then raise the temperature to 580°C for 25 minutes, and maintain it for 15 minutes. After closing the muffle furnace and cooling down naturally, take out the oil sample glass bottle, and observe with the naked eye, there is no residual oil, coke or impurities, the oil in it has been volatilized, the bottle is clean and transparent, and the bottle is not deformed, and can be used directly for subsequent use.

Abstract

The invention provides a purification method of a glass oil sample bottle. The purification method comprises the following steps: (1) inverting the glass bottle which is used for containing an oil sample to enable residual oil liquid in the glass bottle to flow out; and (2) putting the treated glass bottle treated in the step (1) into a muffle furnace, and carrying out heating according to the following temperature rising program: in first-stage heating, the temperature is increased to 260-280 DEG C, and the time required for controlling the heating process of the first stage is more than or equal to 30 minutes; then in second-stage heating, temperature is increased to 550-580 DEG C, and the time required for controlling the heating process of the second stage is more than or equal to 20 minutes; and then in third-stage heating, heat preservation is carried out, and the temperature is kept at 550-580 DEG C for 10 minutes or above. The invention provides the purification method of the glass oil sample bottle, and the purification method is convenient and simple, is high in operability, and has a good oil removing effect.

Description

technical field [0001] The invention relates to the technical field of degreasing and decontaminating glass containers, in particular to a method for purifying an oil sample bottle made of glass. Background technique [0002] In various fields related to the use of oil products, glass containers are often used to hold oil samples. When cleaning these glass containers, volatile chemical solvents (such as solvent gasoline, tetrachloroethylene) are often used for cleaning. On the one hand, the volatility of these solvents will cause local working environment pollution, which is not conducive to the health of operators; on the other hand, the cleaning effect is not thorough, which is likely to cause oil residues. Therefore, it is a research direction for those skilled in the art to explore and study a convenient, simple and highly operable glass oil sample bottle degreasing method. Contents of the invention [0003] In view of this, the present invention provides a purificati...
