[0002] Crude oil needs to be added when preparing the desulfurizer. Before the crude oil is added to the prepared reactant, its freezing point needs to be tested using a freezing point detector to find out whether it can meet the reaction requirements when dissolved in the preparation. There is a socket on the freezing point detector, and a refrigeration cavity is provided in the detector. The bottom of the socket is connected to the refrigeration cavity, and the refrigeration cavity has a refrigeration function (refrigeration medium such as refrigeration oil, etc.). The button on the instrument is operated to lower the temperature until the crude oil solidifies in the test tube. Through this refrigeration temperature, the freezing point of the crude oil can be known.

[0003] In the existing testing process, the test tube is manually pulled out from the socket of the instrument, and then the test tube is tilted to see whether the liquid level flows, so as to know whether the crude oil has reached the freezing point under a certain low temperature condition. If the oil still flows during the testing process, it proves that it has not reached the freezing point. The test tube needs to be inserted into the instrument again along the socket, and after a period of cooling, the test tube can be pulled out. The manual operation efficiency is low and needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0023] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0024] In one embodiment, Figure 1-Figure 6 As shown: This embodiment provides a crude oil condensation point measuring instrument for desulfurization agent preparation, including an instrument body 1, a detection port 2 provided at one end of the top surface of the instrument body 1, a clamping mechanism 3 provided in the detection port 2, a test tube 4 inserted in the detection port 2, and a driving mechanism 5 located in the instrument body 1 for controlling the clamping mechanism 3 to drive the test tube 4 to tilt and deflect; the existing measuring instrument (pour point and condensation point measuring instrument on the market) has a refrigeration function, such as the instrument body 1 in the present invention is an existing measuring instrument, and it is also provided with a detection port 2, the detection method is to pour the crude oil into the test tube 4 after sampling, and then insert the test tube 4 into the instrument body 1 through the detection port 2, and after starting the panel button, the refrigeration function in the instrument body 1 cools the test tube 4 until the crude oil in the test tube 4 is condensed at a certain low temperature. In addition, the present invention also provides a driving mechanism 5 in the instrument body 1, and after the device cools the test tube 4 at a certain low temperature for a period of time, it is not necessary to manually pull out the test tube 4 and tilt to observe whether the crude oil is condensed, and the above self-detection action can be automatically completed by the driving mechanism 5, saving labor.

[0025] First, Figure 2 As shown, the driving mechanism 5 includes a driving cylinder 6 and a push seat 7 fixed on the actuating rod of the driving cylinder 6. When the bottom of the test tube 4 is inserted into the instrument body 1, it is located on the movement path of the push seat 7. The relevant buttons on the start panel make the driving cylinder 6 (electric cylinder or hydraulic cylinder) work, and its actuating rod extends outward and pushes the push seat 7 forward. The push seat 7 pushes the inclined surface 26 against the bottom end of the test tube 4. As the actuating rod brings the push seat 7 forward, the push seat 7 applies pressure to the bottom end of the test tube 4 through the inclined surface 26, and finally forces the test tube 4 to automatically move upward along the inclined surface of the push seat 7, so as to achieve the purpose of gradually exposing the crude oil level from the inside of the instrument body 1 to the top of the instrument body 1, which is convenient for the operator to observe with the naked eye.

[0026] In addition, a rotatable carrier 8 is installed in the detection port 2 through a pin shaft. When the test tube 4 is inserted into the detection port 2, the bottom end falls on the carrier 8, so the test tube 4 can rotate under the drive of the carrier 8. The driving mechanism 5 also includes a toothed disc 9 fixed on the carrier 8, and a rack 10 fixed on the push seat 7. When the push seat 7 pushes the test tube 4 up in the above manner and exposes the liquid level of the crude oil in the test tube 4 to the naked eye, as the push seat 7 continues to move forward with the rack 10, the rack 10 rotates with the toothed disc 9. Since the toothed disc 9 is installed on the carrier 8, and the test tube 4 is installed on the carrier 8, once the toothed disc 9 rotates, it will deflect the carrier 8, and the carrier 8 will deflect the test tube 4, so that the crude oil in the test tube 4 The oil level is tilted within the visual range. At this time, if the liquid level flows with the deflection of the test tube 4, the crude oil has not reached the condensation condition. The set temperature of the instrument body 1 is not the condensation point of the crude oil. The push seat 7 is reversed and retracted, and the test tube 4 drops again. The rack 10 engages the gear disc 9 and rotates in the opposite direction and then leaves the gear disc 9. The carrier 8 rotates and resets. The test tube 4, with the crude oil, is immersed in the refrigeration medium again. The detection temperature is reset, and the crude oil sample is cooled again. The above operation process is repeated until the test tube 4 rises and the liquid level in the tube no longer flows with the deflection of the test tube 4 driven by the deflection of the carrier 8. The crude oil sample reaches the condensation condition at this low temperature, that is, this low temperature is the condensation point of the crude oil. The detection is completed and recorded.

[0027] In summary, during the detection process, the operator only needs to operate the button, and does not need to frequently pull out the test tube 4 manually, nor does it need to pull the test tube 4 out of the device and tilt it manually, which saves labor and improves efficiency.

[0028] In addition, when the test tube 4 is inserted into the device for testing through the test port 2, it is positioned by the clamping mechanism 3 to ensure that the test tube 4 is vertical, and the crude oil sample below the liquid level is immersed in the refrigerant in the instrument body 1. When the test tube 4 rises and deflects in the above-mentioned way, the clamping mechanism 3 automatically relaxes to form the deflection condition.

[0029] like Figure 2 , Figure 4As shown, the detection port 2 is rectangular, and the clamping mechanism 3 includes a first clamping seat 11 and a second clamping seat 12 fixed in the detection port 2. When the opposite ends of the first clamping seat 11 and the second clamping seat 12 are pressed against the two ends of the carrier 8, the carrier 8 is ensured to be vertical. At the same time, the carrier 8 also ensures that the test tube 4 is vertical, ensuring that the crude oil sample in the test tube 4 can be inserted into the refrigeration medium. An insertion space 13 for inserting the test tube 4 is reserved between the first clamping seat 11 and the second clamping seat 12. The test tube 4 is inserted into the detection port 2 through the insertion space 13, and the bottom end falls on the drop frame 14 at the bottom of the carrier 8, and the top tube body part is exposed above the instrument body 1.

[0030] The carrier 8 is connected to the insertion space 13 through a pin shaft, and the carrier 8 is located between the first clamping seat 11 and the second clamping seat 12. A socket 16 for positioning the test tube 4 is provided on the carrier 8. When the carrier 8 is deflected, the socket 16 is used to provide force to the test tube 4, causing the test tube 4 to deflect.

[0031] Continue with the above Figure 2 , Figure 4 As shown, a rectangular opening 19 is provided on the first clamping seat 11 and the second clamping seat 12. The opening 19 of the first clamping seat 11 faces downward, and a first movable member 20 is slidably installed in the first clamping seat 11. The opening 19 of the second clamping seat 12 faces upward, and a second movable member 21 is slidably installed in the second clamping seat 12. The two openings 19 are connected to one end of the carrier 8. A first elastic member 22 is connected between the first movable member 20 and the other end of the first clamping seat 11, and a second elastic member 23 is connected between the second movable member 21 and the other end of the second clamping seat 12. The first movable member 20 is supported by the elastic support of the first elastic member 22, and the second movable member 21 is supported by the elastic support of the second elastic member 23. The first movable member 20 and the second movable member 21 are both shell structures, wherein a bent rod 24 is connected to the first movable member 20, and the bent rod 24 bends downward and then bends toward the direction of the test tube 4, and an idler wheel 25 is installed at the bent terminal. When the test tube 4 is deflected upward under the push of the push seat 7, the bottom tube wall thereof will press against the idler wheel 25, providing push to the idler wheel 25, and the idler wheel 25 will provide thrust to the bent rod 24, and the bent rod 24 will provide thrust to the first movable member 20, forcing the first movable member 20 to slide along the opening 19 of the first clamping seat 11, and the top tube wall thereof will push the second movable member 21, and force the second movable member 21 to slide along the opening 19, thereby opening the two movable members that originally played a clamping role. In order to enable the test personnel to observe the liquid level of the crude oil in the test tube 4 with the naked eye, the two movable members will not interfere with each other through relative displacement when the test tube 4 is deflected.

[0032] like Figure 2 , Figure 6As shown, the inclined surface 26 on the push seat 7 gradually tilts upward in a manner of gradually moving away from the test tube 4. A connecting rod 27 is welded on the side of the push seat 7, and the rack 10 is fixed on the connecting rod 27. When the push seat 7 is pressed against the test tube 4 by the inclined surface 26, the rack 10 is still away from the toothed disc 9. Only after the push seat 7 pushes the test tube 4 up a certain distance by the inclined surface 26, the rack 10 is engaged with the toothed disc 9 to drive the toothed disc 9 to rotate. The test tube 4 is first pushed upward by the push seat 7 (the liquid level of the crude oil sample rises to the top of the instrument body 1), and then deflected by the deflection of the carrier 8 (the liquid level of the crude oil sample is tilted above the instrument body 1 for easy viewing).

[0033] like Figures 2 to 6 As shown, the bottom of the carrier 8 is provided with an inclined plate 17 which is gradually inclined downward in one direction, and a hollow hole 15 is opened on the inclined plate 17, and the bottom end of the test tube 4 falls on the inclined plate 17. The refrigerant in the instrument body 1 passes through the hollow hole 15 to submerge the crude oil at the bottom of the test tube 4. The opening of the hollow hole 15 ensures that the refrigerant gradually cools the test tube 4.

[0034] like Figure 6 As shown, the carrier 8 is provided with a through slot 18 facing the outer wall of the test tube 4. The weight is reduced, and when the test tube 4 is inserted into the instrument body 1 for cooling, the cooling medium in the instrument body 1 can pass through the through slot 18 to provide cooling conditions for the test tube 4, and the structure of the carrier 8 is reasonable.
