Description

Technical Field

[0001] The utility model belongs to the technical field of crude oil sampling, and in particular relates to a sealed sampling device for crude oil purification. Background Art

[0002] At present, during the crude oil purification process, it is usually necessary to use a sampling device to sample the crude oil. The existing carbon black crude oil sampler includes a sampling tube, a first mounting plate, a connecting rod, a sealing seat, a sealing plug, a spring, a second mounting plate, a fixed pulley and a pull wire. The first end of the sampling tube is fixedly connected to the first mounting plate, and the second end of the sampling tube is connected to the sealing seat; the connecting rod passes through the first mounting plate and the center of the sampling tube. When using this crude oil sampling device, the user needs to manually sample, and the sampling tube after sampling needs to be cleaned before reuse, and direct replacement is costly. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a sealed sampling device for crude oil purification, which is convenient for replacing the sampling tube and saves the cost of cleaning or replacement.

[0004] The utility model is realized by the following technical solutions:

[0005] A sealed sampling device for crude oil purification includes a sampling tube, characterized in that gripping protrusions are integrated on both sides of the sampling tube, an upper connector is integrated on the upper end of the sampling tube, a lower connector is integrated on the lower end of the sampling tube, and an annular protrusion is integrated on the outside of the lower end of the sampling tube.

[0006] Preferably, the sampling tube is also provided with a lower screw cap and an upper screw cap.

[0007] Preferably, the external thread provided on the outside of the upper connector is adapted to the internal thread provided on the inside of the upper screw cap.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. In the utility model, the arrangement of the lower screw cap, the upper screw cap, the upper connector, the lower connector, and the annular protrusion is conducive to replacing the sampling tube, saving the cost of cleaning or replacement.

[0010] 2. In the present invention, the provision of the vacuum pump is conducive to extracting the crude oil into the sampling tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a sealed sampling device for crude oil purification includes a sampling tube 1, gripping protrusions 11 are integrated on both sides of the sampling tube 1, an upper connector 12 is integrated on the upper end of the sampling tube 1, a lower connector 13 is integrated on the lower end of the sampling tube 1, and an annular protrusion 14 is integrated on the outside of the lower end of the sampling tube 1.

[0016] In this embodiment, combined with the Figure 2 As shown, the sampling tube 1 is also equipped with an air pump 4. The inlet thread of the air pump 4 is adapted to the internal thread of the upper connector 12. When in use, the user connects the air pump 4 to an external power supply and a control device, and the user inserts the lower connector 13 into the crude oil, starts the air pump 4, and draws the crude oil into the sampling tube 1. The control device sets the running time of the air pump 4, and stops the air pump 4 before the crude oil reaches the upper end of the sampling tube 1, thereby drawing the crude oil into the sampling tube 1.

[0017] In this embodiment, specifically, the sampling tube 1 is further provided with a lower screw cap 2 and an upper screw cap 3 .

[0018] In this embodiment, specifically, the external thread provided on the outside of the upper connector 12 is adapted to the internal thread provided on the inside of the upper screw cap 3 .

[0019] In this embodiment, specifically, the external thread provided on the outside of the annular protrusion 14 is adapted to the internal thread provided on the inside of the lower screw cap 2 .

[0020] In this embodiment, specifically, a circular rubber pad 21 is glued to the lower side of the inner part of the lower screw cover 2 .

[0021] How it works

[0022] In the utility model, the lower screw cap 2 is put onto the outside of the lower connector 13 and connected to the annular protrusion 14, the circular rubber pad 21 seals the lower connector 13, the upper connector 12 is removed from the vacuum pump 4, and the upper screw cap 3 is connected to the upper connector 12, thereby sealing the sampled crude oil.

[0023] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
