Description

The present invention relates to an apparatus for extracting samples of mineral oil deposits and is intended for laboratories and testing facilities for mineral oils.

The oil tests are carried out by pouring a measured amount of mineral oil into a test vessel whose bottom part is an outlet opening covered with filter paper and a sieve. The oil flows into the pre-prepared container and on the filter paper, deposits remain, which are the subject of our own laboratory tests. Existing methods for obtaining deposit samples are lengthy and inaccurate due to the design of the sampling device. This usually consists of a cylindrical vessel, at the bottom of a conical taper, which is closed from above by a lid for the bayonet closure and into which a compressed air line operated by a control cock opens. A metal ring on the wire loop is inserted into the interior of the container, which presses the metal ring in a conical bevel by sealing the cap and thus seals it in the container. A sieve with filter paper is placed on the metal ring. The hydraulic conditions in the narrow cylinder of the container, the leakage around the metal ring and the leak of the bayonet lid cause a disproportionate increase in sampling times and inaccuracies due to leakage of the test sample.

238 981 oil outside the metal ring. In addition, test filters of a similar design are known in which the filter relic is obtained by vacuum pump. This laboratory apparatus operates at an even lower efficiency than the above-described pressure arrangement apparatus.

The above-mentioned drawbacks are eliminated by a device for extracting samples, deposits and impurities from mineral oils, consisting of a container provided with a removable lid, a supply of pressurized gaseous medium at its top and a filter consisting of a metal strainer and filter paper. the essence of the invention is that the cylindrical container is provided with a conical v

The bottom is screwed to the flange of the cylindrical container and is provided with a pouring throat closed by a threaded plug.

The laboratory apparatus of the present invention is operationally safe and operates with great efficiency and reduced test times. The imposition of the filter prevents «cttok and the loss of the oil sample to be leaked, thereby obtaining inaccurate

measurement values.

The device according to the invention is shown in the attached drawing, which represents a half longitudinal axial section of the test vessel χ, which is terminated by a conical bottom χ, which is terminated by a mouth screw extension 2, on which the sleeve 6 is screwed. 6, an inner shoulder 6 is formed, on which a brass sieve 2 and a paper filter 8 are mounted. To the upper part of the cylindrical container χ is a side supply of compressed air 2 or other suitable gaseous medium with pressure regulation. The top flange 10 of the container χ is screwed to the lid XX χχ, which is provided with a pouring spout 12 which is closed by a threaded plug XX.

The sleeve 6 is screwed from the bolt extension 2, the cleaned sieve 2 and a new paper filter 8 are inserted into the housing, and the sleeve χ is screwed on again. A measured quantity of mineral oil is poured into the open pouring spout χ and the spout XX is then closed with a threaded plug 13. The compressed air admitted into the container χ through the inlet 2 pushes the oil through the papermaking filter 8 and the wire screen 2 into the prepared container.
