Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for crude oil dehydration experiments. Background Art

[0002] At present, in crude oil dehydration experiments, the dehydrated crude oil is often sampled and analyzed. Since the water content of the crude oil in the upper, middle and lower layers of the test bottle is different, three samples from the upper, middle and lower layers are generally taken for analysis during the sampling process.

[0003] The existing Chinese patent publication number is CN203837962U, a sampler for crude oil dehydration experiment. It can be seen from the contents recorded in its specification that when the device is in use, the pipette is mainly fixed to the experimental bottle by fixing screws. This installation method can only be used for experimental bottles of specific specifications, and its applicable specifications are relatively low, thereby reducing the scope of application of the device.

[0004] Therefore, it is necessary to provide a new crude oil dehydration experimental sampling device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 4 The embodiment of the utility model provides a sampling device for crude oil dehydration experiment, and the sampling device for crude oil dehydration experiment includes: a frame 1.

[0024] In the embodiments of the present invention, please refer to Figures 1 to 4 A support sheet 12 is fixedly mounted on one side wall of the frame 1, a support bracket 4 is fixedly mounted on the support sheet 12, a sampling syringe 5 is placed on the support bracket 4, a movably connected sampling tube 3 is provided inside the frame 1, and a connecting hose 51 is provided between the sampling tube 3 and the sampling syringe 5.

[0025] It should be noted that: through the support of the sampling tube 3 by the frame 1, during use, the frame 1 only needs to be set on the outside of the experimental bottle, so that the sampling tube 3 is located above the experimental bottle to complete the installation of the sampling tube 3. This installation method has a wide range of applications and few limitations, thereby improving the scope of application and use experience of the device;

[0026] By using the connecting hose 51 to connect the sampling tube 3 with the sampling syringe 5, when the position of the sampling tube 3 is adjusted in later use, the connecting hose 51 can move synchronously with the sampling tube 3, thereby avoiding obstruction to the movement of the sliding bar 21.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 4 The frame 1 is provided with an adjusting component 2, which includes a rotating rod 22, which is rotatably connected to the top of the frame 1, and a rotatably connected driving rod 23 is mounted below the rotating rod 22 at the top of the frame 1, and a fixedly connected worm 231 is sleeved on the outer wall of the driving rod 23, and a meshing worm wheel 232 is provided on the outside of the worm 231, and the worm wheel 232 is fixedly sleeved on the rotating rod 22. The adjusting component 2 also includes a sliding bar 21, and a plurality of evenly distributed and fixedly connected connecting teeth 212 are provided on the outer wall of the sliding bar 21, and a fixedly connected gear 221 is sleeved on the outer wall of the rotating rod 22, and the gear 221 is meshingly connected with the connecting teeth 212.

[0028] It should be noted that: when the driving rod 23 is controlled to rotate during use, the rotating driving rod 23 will drive the worm 231 on the outer wall to rotate, and the rotating worm 231 will drive the rotating rod 22 to rotate through the meshing connection with the external worm gear 232. At this time, the rotating rotating rod 22 will drive the gear 221 on the outer wall to rotate synchronously, and the rotating gear 221 will drive the sliding bar 21 to move inside the guide groove 11 through the meshing with the connecting teeth 212. The moving sliding bar 21 will drive the internal sampling tube 3 to move synchronously, so that the sampling tube 3 can be inserted into the interior of the experimental bottle more stably and accurately.

[0029] By means of the self-locking characteristics of the worm wheel 232 and the worm 231 , after the position of the sliding bar 21 is adjusted later, the sliding bar 21 can be prevented from randomly moving, so that the sliding bar 21 can stably support the sampling tube 3 .

[0030] In the embodiments of the present invention, please refer to Figures 1 to 4 A guide groove 11 is opened inside the frame 1, and the inner wall of the guide groove 11 abuts against and is slidably connected to the outer wall of the sliding bar 21, and the inner wall of the guide groove 11 and the outer wall of the sliding bar 21 are both cross-shaped structures. An installation groove 211 is opened inside the sliding bar 21, and the inner wall of the installation groove 211 is fixedly connected to the outer wall of the sampling tube 3.

[0031] It should be noted that by setting the guide groove 11 and the sliding bar 21 as a cross-shaped structure, when the driving component drives the sliding bar 21 to slide, the cross-shaped structure can prevent the sliding bar 21 from tilting inside the guide groove 11, thereby making the subsequent movement of the sliding bar 21 more stable.

[0032] The working principle of the crude oil dehydration experiment sampling device provided by the utility model is as follows:

[0033] When using the device, the staff can lift the device and cover the frame 1 on the outside of the sampled experimental bottle, and then control the driving rod 23 to rotate, and the rotating driving rod 23 will drive the worm 231 on the outer wall to rotate, and the rotating worm 231 will drive the rotating rod 22 to rotate through the meshing connection with the external worm wheel 232;

[0034] At this time, the rotating rod 22 will drive the gear 221 on the outer wall to rotate synchronously, and the rotating gear 221 will drive the sliding bar 21 to move inside the guide groove 11 through meshing with the connecting tooth 212. The moving sliding bar 21 will drive the internal sampling tube 3 to move synchronously, so that the sampling tube 3 can be inserted into the interior of the experimental bottle more stably and accurately.

[0035] After the sampling tube 3 is inserted, the staff can collect the sampling syringe 5, and the use of the device is now completed.

[0036] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
