Embodiment 1

[0025] Example 1, as figure 1 , image 3 , Figure 4 and Figure 5 As shown, the present invention is a method for cleaning a sampling clean bottle for oil inspection, comprising the following steps: 1. using a filtration and purification device to filter and purify the petroleum ether solvent; The clean bottle 11 is a PET transparent plastic round mouth square bottle. The inside of the bottle body is smooth and wrinkle-free, and the inside of the bottle body has no dead corners for cleaning. The bottle mouth is provided with a PP material sealing bottle cap; slot type. Capacity 250ml.

[0026] The concrete steps of step 1 are: S1, take unopened petroleum ether solvent, utilize filtration and purification device to carry out crude filtration to petroleum ether once; The conical flask 9 and the red-head washing bottle 10 are cleaned with the crudely filtered petroleum ether solvent, and then the cleaning solution is poured into the conical flask 9 again, S3, the petroleum ...

Embodiment 2

[0028] Example 2, on the basis of Example 1, the filter membrane used in the rough filtration in the step S1 in the step 1 is a specification 50mm*0.5um organic filter membrane 5, and the secondary filtration in the step S3 in the step 1 is used. The filter membrane used is an organic filter membrane 5 with a specification of 50mm*0.2um.

[0029] The detailed steps of step S2 in the step 1 are as follows: pour the crudely filtered petroleum ether part into the conical flask 9, cover the bottle, shake it up and down, left and right for no less than half a minute, and use petroleum ether to clean the conical flask. Inside the bottle 9; pour some petroleum ether into the red head washing bottle 10, screw on the bottle cap, shake it up and down, left and right for no less than half a minute, use petroleum ether to clean the inside of the red head washing bottle 10, and finally pour all the petroleum ether into the conical flask 9 in.

[0030]After the S3 step in the first step is...

Embodiment 3

[0034] Example 3, as figure 2 As shown, the filtering and purifying device in Embodiment 1 or 2 includes a filter bottle 8, a sand core filter device 7 is connected above the filter bottle 8, an organic filter membrane 5 is provided above the sand core filter device 7, and the upper part of the sand core filter device 7 A clip 6 is connected, the upper part of the clip 6 is fixed with a sand core filter cup 4 , the lower part of the sand core filter device 7 is provided with an air suction port 3 , and the air suction port 3 is connected with a vacuum pump 1 . The filter bottle is 1000ml.

[0035] The top outer wall of the filter bottle 8 is installed in the bottom inner hole of the sand core filter device 7 in a frosted sealing fit, and this fit can form an airtight seal.

[0036] The air suction port 3 is connected with an air suction hose 2 , and the air suction hose 2 is connected with the vacuum pump 1 , and an anti-slip protrusion is provided on the outside of the air ...

Abstract

The invention relates to a method for cleaning a sampling clean bottle for oil product inspection, comprising the following steps: 1. Using a filtering and purifying device to filter and purify petroleum ether solvent; 2. Using filtered petroleum ether to clean the sampling clean bottle; the sampling clean bottle It is a PET transparent plastic round mouth square bottle, the inside of the bottle body is smooth and wrinkle-free, and there is no cleaning dead angle inside the bottle body, and the bottle mouth is provided with a PP material sealing bottle cap; the cleaned sampling clean bottle of the present invention has a high level of cleanliness, and the inside of the sample clean bottle The cleanliness level reaches NAS16380-1 level, which meets the standard of clean bottles for qualified sampling. The sampling clean bottle and the solvent are selected reasonably, and the cost of both is very low; the inside of the clean sampling bottle is smooth and has no dead ends, no residue, and is easy to clean. The solvent has good chemical stability and good effect, and has no effect on the cleanliness test results of oil products. Improve on-site production efficiency, improve the accuracy of oil cleanliness test results, save the cost of oil purification, help enterprises save energy and reduce consumption, and increase profit margins.

Description

technical field [0001] The invention belongs to the technical field of oil product inspection, and in particular relates to a cleaning method for a sampling clean bottle for oil product inspection. Background technique [0002] For the existing sampling clean bottles for oil cleanliness testing, used mineral water bottles, beverage bottles or wide-mouth bottles are generally used in on-site production. The problems of these bottles are: 1. There are residual water and impurities inside the bottle body, and the bottle The non-smooth structure inside the body leads to the accumulation of dirt and dirt, the structure of the bottle body leads to the existence of dead corners in the mouth and inside of the bottle, and the cleaning is not clean during cleaning; 2. There are also various problems in the selection of cleaning solvents: the cleaning solvent itself is very clean Low, resulting in low cleanliness level of the cleaned sampling bottle; the cleaning solvent selected on si...
