Technical Field

[0001] The utility model relates to the technical field of oil testing, in particular to a freezing point and pour point tester. Background Art

[0002] Pour point and solidification point are important quality indicators of petroleum products. Lubricating oil is blended from various base oils extracted from petroleum, so the pour point and solidification point are also important quality indicators for measuring lubricating oil. When measuring oil, a pour point and solidification point meter is needed.

[0003] When using traditional measuring equipment, the measuring tube needs to be placed in a cold bath during the measurement process, and the temperature of the tube needs to be lowered in the cold bath. The tube needs to be taken out continuously during the temperature drop and tilted for observation. Traditional equipment requires manual operation when taking and tilting the tube. The temperature of the tube is low after the cold bath, which will have a certain impact on the experimenter's hands. The manual taking and tilting throughout the process makes the equipment inconvenient to use. Utility Model Content

[0022] By installing a lifting motor 4 in the inner cavity of the equipment body 1 and a driving screw 5 on the outer wall of the power output shaft of the lifting motor 4, the driving screw 5 will be driven to rotate under the action of the lifting motor 4. In the process of rotating the driving screw 5, the lifting block 6 can move up and down along the outer wall of the driving screw 5, thereby adjusting the height of the lifting block 6, so that the No. 1 experimental tube 13 can be moved out of the inner cavity of the cold bath tube 3 more smoothly.

[0023] In a preferred embodiment, the opening position of the cold bath tube 3 corresponds to the installation position of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 , and the inner wall diameter of the cold bath tube 3 is larger than the outer wall diameter of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 .

[0024] By setting the No. 1 experimental tube 13 and the No. 2 experimental tube 17 on the outer wall of the support plate 7, after the height of the support plate 7 is lowered under the action of the lifting motor 4 and the driving screw 5, the outer walls of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 will enter the inner cavity of the cold bath cylinder 3, so that the oil in the inner cavity of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 can be cooled, which is convenient for subsequent measurements.

[0025] In a preferred embodiment, the outer wall of the driving gear 12 meshes with the outer wall of the driven gear 10 , and the outer wall diameter of the driving gear 12 is smaller than the outer wall diameter of the driven gear 10 .

[0026] By means of a driven gear 10 provided on the outer wall of the driving rod 8 and a driving gear 12 provided on the power output shaft of the driving motor 11, the driving gear 12 is driven to rotate under the action of the driving motor 11, so that the driving rod 8 is rotated in the inner cavity of the support plate 7 under the action of the driving gear 12 and the driven gear 10, thereby driving the No. 1 experimental tube 13 in the inner cavity of the fixing frame 9 to tilt along the outer wall of the driving rod 8.

[0027] In a preferred embodiment, the outer wall of the connecting plate 14 away from the fixing frame 9 is rotatably connected to the outer wall of the mounting frame 15 , and the connecting plate 14 , the fixing frame 9 and the mounting frame 15 are all made of stainless steel.

[0028] By providing a connecting plate 14 on the outer wall of the fixing frame 9, and with both ends of the outer wall of the connecting plate 14 being rotatably connected to the outer walls of the fixing frame 9 and the mounting frame 15 respectively, when the driving rod 8 and the fixing frame 9 rotate under the action of the driving gear 12 and the driven gear 10, the outer wall of the No. 1 experimental tube 13 will tilt during the rotation process, so that the inclination angle of the mounting frame 15 is kept consistent with the inclination angle of the fixing frame 9 under the drive of the connecting plate 14.

[0029] In a preferred embodiment, a control panel is installed on the outer wall of the equipment body 1 , and the control panel is electrically connected to the lifting motor 4 and the driving motor 11 respectively.

[0030] By means of a control panel provided on the outer wall of the equipment body 1, the drive motor 11 is controlled under the action of the control panel, so that the drive motor 11 drives the rotation of the drive gear 12, thereby achieving the tilting of the angle of the outer wall of the fixed frame 9, and thereby the angle of the No. 1 experimental tube 13 in the inner cavity of the fixed frame 9 can also be tilted. At this time, it can be observed whether the oil in the inner cavity of the No. 1 experimental tube 13 is flowing.

[0031] In a preferred embodiment, a slide groove is provided in the inner cavity of the support frame 2 , and the shape of the inner wall of the slide groove matches the shape and size of the outer wall of the lifting block 6 .

[0032] Through the slide groove opened on the outer wall of the support frame 2, under the action of the lifting motor 4 and the driving screw 5, the lifting block 6 can move up and down in the inner cavity of the slide groove, thereby pulling the No. 1 experimental tube 13 and the No. 2 experimental tube 17 upward from the inner cavity of the cold bath tube 3, and the experimenter does not need to manually take the No. 1 experimental tube 13 out of the inner cavity of the cold bath tube 3.

[0033] Working principle: When the above-mentioned equipment is in use, when it is necessary to measure the freezing point and pour point of the oil, the oil to be tested is added to the inner cavity of the No. 1 experimental tube 13 and the No. 2 experimental tube 17, and then the top of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 is inserted into the closing plug, and then the lifting motor 4 is started under the action of the control panel, and the driving screw 5 is driven to rotate under the action of the lifting motor 4, and then the height of the lifting block 6 is raised and lowered during the rotation of the driving screw 5, so that the No. 1 experimental tube 13 and the No. 2 experimental tube 17 enter the inner cavity of the cold bath tube 3, and then a cold bath can be carried out in the inner cavity of the cold bath tube 3. After a period of cold bath, the inner cavities of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 are filled with water. The oil temperature is lowered. At this time, the height of the lifting block 6 is adjusted upward to move the No. 1 experimental tube 13 and the No. 2 experimental tube 17 out of the inner cavity of the cold bath tube 3. Then, the driving motor 11 is started. Under the action of the driving motor 11, the driving gear 12 is driven to rotate, so that the fixing frame 9 and the driving rod 8 are rotated under the action of the driven gear 10. By controlling the rotation time of the driving motor 11, the outer wall of the fixing frame 9 can be tilted. At this time, the No. 1 experimental tube 13 and the No. 2 experimental tube 17 will both tilt at a certain angle. At this time, it can be observed whether the oil in the inner cavity of the No. 1 experimental tube 13 and the No. 2 experimental tube 17 flows, so that the freezing point and pour point of the oil can be obtained after repeated experiments.
