Technical Field

[0001] This utility model belongs to the field of sampling device technology, specifically relating to an oil sampling device. Background Technology

[0002] In petrochemical processing, petroleum samples are often taken for testing to confirm that the petroleum materials used can meet the state and property requirements of the processing stage. Currently, the conventional sampling method mostly uses glass containers similar to syringes for sampling. However, when it is necessary to sample different types of petroleum samples, this sampling method has the problem of frequently changing containers and re-inserting into the petroleum for sampling, which results in inconvenient operation and complicated sampling steps.

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-4As shown, an oil sampling device includes a grip tube 1 and a sampling probe. The upper end of the grip tube 1 has several storage chambers 11, and each storage chamber 11 is provided with a storage tube. The other end of the grip tube 1 is provided with an adjustment mechanism.

[0024] Adjusting cover 12 is the main connecting device and adjusting device in the adjusting mechanism. Adjusting cover 12 is rotatably and sealed to grip tube 1. Several storage cavities 11 are opened with liquid passages 13 that communicate with adjusting cover 12. Sampling probe is connected to the lower end of adjusting cover 12 and its movement trajectory matches the circular trajectory formed by several liquid passages 13.

[0025] Tube body 2 is the storage container in the sampling probe, and the tube body 2 is threadedly connected to the storage cavity 11.

[0026] The aspirator is the suction structure in the sampling probe, and the sampling tube is slidably sealed inside the tube body 2.

[0027] Before sampling, the storage tube is first inserted into the grip tube 1 for preparation. The tube body 2 of the storage tube is connected to the storage cavity 11 by a thread, which makes the storage tube less likely to fall off and plays a role in stabilizing the connection. Then, all the suction devices of the storage tubes are reset to the initial state, i.e., ready for suction.

[0028] Once preparation is complete, oil sample collection can begin. To collect the sample, first rotate the adjusting cap 12 so that the sampling probe on the adjusting cap 12 is aligned with one of the storage tubes. Alignment is determined by observing the markings on the adjusting cap 12. Alternatively, you can observe the position between the sampling probe and the storage tube to determine if they are aligned. Then, insert the sampling probe into the open oil container, into the oil storage container, or through the sampling port. Finally, use a suction device to draw the oil sample into the storage tube, thus completing the sampling process.

[0029] When it is necessary to sample another type of oil, the position of the sampling probe can be adjusted again by rotating the adjustment cover 12, so as to achieve sampling of different types of oil samples, allowing different types of oil samples to be stored separately. At the same time, the storage containers are independent, which is convenient for subsequent testing needs. In addition, the storage tube can be replaced in real time according to the sampling quantity needs to meet the needs of single-time variety and sampling quantity and angle.

[0030] The threaded connection between the tube body 2 and the storage cavity 11 is located on the upper side of the tube body 2.

[0031] This allows for a fast and stable connection after the tube 2 has almost completely fallen into the storage cavity 11.

[0032] The upper end of the tube body 2 is provided with a protruding ring 21.

[0033] The protruding ring 21 makes it easier to rotate the tube body 2.

[0034] The suction device includes a handle 22, a connecting rod 23 and a piston 24. The piston 24 is slidably sealed inside the tube body 2. The connecting rod 23 is connected to the piston 24 and slides out of the tube body 2 before connecting to the handle 22.

[0035] During sample extraction, pulling the handle 22 moves the piston 24 via the connecting rod 23. The piston 24 generates negative pressure inside the tube 2, drawing the petroleum sample into the tube 2 through the liquid passage 13. Atmospheric pressure and the sealing effect of the regulating cap 12 ensure that the petroleum sample will not leak. To further improve the sealing and sampling stability, a pressure valve 4 is provided between the tube 2 and the liquid passage 13. Depending on the specific application environment, the pressure valve 4 can be a two-way pressure valve or a one-way pressure valve. When the pressure valve 4 is a one-way pressure valve, only petroleum is allowed to be drawn into the tube 2. The petroleum sample can only be discharged when the pressure valve 4 is removed during subsequent testing to improve sample stability. When the pressure valve 4 is a two-way pressure valve, the petroleum sample can be homogenized through the pulling action during the aspiration process to improve the uniformity of the extracted petroleum sample. Therefore, this application does not impose specific restrictions on the type of pressure valve 4.

[0036] The tube body 2 is also equipped with a cleaner, which includes a movable ring 3, an extension rod 31, a cleaning ring 32 and a positioning ring 33. The movable ring 3 is slidably disposed on the side of the grip tube 1. The extension rod 31 is connected to the movable ring 3 and extends to the side of the adjustment cover 12. The length of the extension rod 31 matches the length of the sampling probe. The cleaning ring 32 is connected to the extension rod 31 and is slidably and sealingly connected to the sampling probe. The positioning ring 33 is disposed on the upper part of the grip tube 1 and is magnetically matched with the movable ring 3.

[0037] Furthermore, to avoid wasting oil samples, after a single oil sample is collected, the extension rod 31 can be pushed to move the cleaning ring 32 up and down along the sampling probe, thereby cleaning and removing most of the residual oil on the sampling probe. This facilitates subsequent sampling and reduces oil dripping waste and environmental pollution. When not in use, the live ring and the positioning ring can be mutually adsorbed and connected, thus preventing the live ring and the cleaning ring from obstructing the sampling probe and ensuring that the position of the live ring is fixed.

[0038] A handle 14 is provided on the side of the grip tube 1.

[0039] This makes it easier to carry and handle the device.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
