[0002] Before use, petroleum must be processed to make petroleum products suitable for various purposes. The most common processing method is distillation, which uses the principle of different molecular sizes and boiling points to separate the hydrocarbons in petroleum, and then uses chemical treatment methods to increase the value of the product. Petroleum distillation is a method of separating a mixture of several different boiling points in petroleum, which is a physical change. The main equipment required for petroleum distillation is called a distillation tower.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] like Figure 1-4 A fractionating tower for petroleum refining shown in the figure comprises a tower body 1 and a plurality of diverter pipes 2 installed on the outer wall of the tower body 1, a vertical lifting plate is installed on one side of the plurality of diverter pipes 2, a temperature sensor 3 is installed on the outer wall of the diverter pipe 2 close to the lifting plate, a lifting and movable calibration platform mechanism is installed on the lifting plate, a left-right movable calibration component is installed on the calibration platform mechanism, and the calibration component moves to the temperature sensors 3 on different diverter pipes 2 for calibration;

[0020] Based on the above, the diverter pipe 2 is used for the fractionation and transportation of different hydrogen compounds. A temperature sensor 3 is separately arranged on each diverter pipe 2 to accurately obtain the working temperature of the diverter pipes 2 at different heights of the distillation tower, and the lifting plate is used to drive the calibration table mechanism to lift and lower, so as to realize the lifting and lowering adjustment of the height of the calibration component. When the calibration component moves to the diverter pipe 2 at the corresponding height, it moves left and right to fit on the outer wall of the diverter pipe 2, and the temperature sensor 3 on the outer wall of the diverter pipe 2 is calibrated. There is no need for manual climbing, the risk is low and the work efficiency is improved.

[0021] The lifting plate comprises a positioning plate 4 located outside the tower body 1, a rib plate 5 for fixing is connected between the positioning plate 4 and the outer wall of the tower body 1, end plates 6 extending outward are arranged at the top and bottom of the positioning plate 4, bearings 7 are embedded in the two end plates 6, rotating screws 8 are inserted in the two bearings 7, a driving motor 9 is connected to the bottom of the screw 8, and the driving motor 9 is fixed to the bottom of the end plate 6 located below;

[0022] Based on the above, during operation, the drive motor 9 is used to drive the screw 8 to rotate in the bearings 7 of the upper and lower end plates 6, and the rotating screw 8 is used to drive the calibration table mechanism and the calibration components to perform lifting activities.

[0023] The inspection platform mechanism includes a platform 10 sleeved on the outside of the screw 8, a threaded tube 11 is installed on the platform 10, the threaded tube 11 is sleeved on the outside of the screw 8, and a plurality of balls 12 are installed at the edge of the platform 10, and the plurality of balls 12 are attached to the outer wall of the positioning plate 4;

[0024] Based on the above, when the driving motor 9 drives the screw 8 to rotate, the screw 8 rotates in the threaded tube 11, and the edge of the table 10 is limited by the ball bearings 12 on the positioning plate 4. Therefore, when the screw 8 rotates, it will drive the Tianan to move up and down along the screw 8. Several ball bearings 12 reduce the friction between the table 10 and the positioning plate 4, reduce working noise and improve smoothness.

[0025] The calibration component includes a hanging plate 13 fixed to the bottom of the table 10, a sleeve 14 is installed at the bottom of the hanging plate 13, a connecting rod 15 sliding left and right is inserted in the sleeve 14, and the connecting rod 15 is perpendicular to the outer wall of the shunt pipe 2;

[0026] A calibration cover 16 with an opening is installed at the end of the connecting rod 15 close to the side of the shunt pipe 2, the opening of the calibration cover 16 faces the side of the shunt pipe 2, a calibration sensor 17 is installed in the inner cavity of the calibration cover 16, and a sealing ring 18 that matches the outer wall of the shunt pipe 2 is installed at the edge of the opening of the calibration cover 16;

[0027] A servo push rod 19 is installed at the end of the connecting rod 15 away from the calibration cover 16 , and a fixing plate is sleeved on the outside of the servo push rod 19 , and the fixing plate is fixed at the edge of the table 10 .

[0028] Based on the above, the drive motor 9 is a motor that can perform forward and reverse rotation. Through its forward and reverse rotation, it drives the platform 10 to rise or fall on the screw 8, so that the calibration component can be raised and lowered on one side of the shunt pipe 2, so that the calibration component can be moved to the shunt pipe 2 at different heights to calibrate the temperature sensor 3 on the outer wall of the shunt pipe 2.

[0029] Furthermore, when the table 10 drives the calibration component to move to the shunt pipe 2 at the corresponding height, the servo push rod 19 is used to push the connecting rod 15 to move to one side of the shunt pipe 2, so that the calibration cover 16 at the end of the connecting rod 15 moves to the outer wall of the shunt pipe 2, and the opening of the calibration cover 16 is tightly fitted on the outer wall of the shunt pipe 2, and the sealing ring 18 is used to make the end of the calibration cover 16 fit tightly with the outer wall of the shunt pipe 2, and the temperature sensor 3 on the surface of the shunt pipe 2 is installed inside the calibration cover 16, so that a relatively sealed and stable environment is formed inside the calibration cover 16, and then the calibration sensor 17 in the calibration cover 16 is used to obtain the temperature of the shunt pipe 2, and compared with the temperature data obtained by the temperature sensor 3 on the outer wall of the shunt pipe 2, to realize the spot inspection and verification of the temperature sensor 3.

[0030] Based on the above, the temperature sensor 3 is covered with the calibration cover 16 to form a sealed environment. During the calibration process, the inspection environment is more stable, the external influence during the temperature calibration process is reduced, and the accuracy of the spot inspection and calibration is improved.

[0031] After the inspection is completed, the servo push rod 19 is used to drive the verification cover 16 to separate from the separation tube, and then the verification cover 16 is driven to move to the diversion tube 2 at another height for subsequent inspection and verification.
