Description

Technical Field

[0001] The invention mainly relates to the technical field of gear oil production, in particular to a temperature-adjustable blending kettle for producing long-life gear oil and a production process thereof. Background Art

[0002] In order to increase the service life of gear oil, the gear oil needs to be catalytically dewaxed. Catalytic dewaxing of gear oil improves the structure and properties of the oil, increases the viscosity index, and reduces the pour point, which helps to extend the service life of the gear oil. At the same time, improving the quality of the oil also has a positive impact on the increase in the service life of the gear oil.

[0003] Catalytic dewaxing is to selectively crack the normal alkanes with high freezing points and isoalkanes with short side chains in the molecular sieve pores into gas and low freezing point hydrocarbon molecules in the presence of hydrogen and selective shape-selective molecular sieve catalysts, using the unique pore structure and appropriate acid centers of the molecular sieve, thereby reducing the freezing point or pour point of the oil. This process is also called selective catalytic hydrocracking dewaxing.

[0004] During the catalytic dewaxing process, the catalytic effect of the molecular sieve plays an important role in the dewaxing effect of the oil. During the catalytic dewaxing process, the molecular sieve located in the outer layer is more easily saturated and more likely to produce carbon deposits. After the outer molecular sieve is saturated or carbon deposits are produced, the catalytic effect of the molecular sieve column is affected, but the inner molecular sieve still has a catalytic effect. At this time, the regeneration of the molecular sieve column cannot achieve the maximum utilization rate. Summary of the invention

The oil collecting hopper 612 is connected to the ring 611, and the oil drain pipe 613 with one end connected to the collecting ring 611 and the other end passing through the sealing plate 23 and extending to the lower part of the sealing plate 23, and also includes an oil circulation component 63 arranged on the bracket 21, the oil circulation component 63 includes a circulation pump 631 arranged on the bracket 21, and an electromagnetic valve 632 whose output end is connected to the input end of the circulation pump 631 through a pipeline, the input end of the electromagnetic valve 632 is connected to the first oil drain pipe 61 and the discharge end of the second oil drain pipe 62, and the output end of the circulation pump 631 is connected to the input end of the mixing chamber 11.

[0048] It should be noted that, in this embodiment, when processing the gear oil, the oil and hydrogen are added to the mixing chamber 11 in proportion, and the agitator in the mixing chamber 11 stirs the oil, while the temperature module and the pressure module in the tank body 10 adjust the temperature and pressure in the mixing chamber 11;

[0049] After the mixing is completed, the oil in the mixing chamber 11 is introduced into the molecular sieve column 30 through the liquid guiding device 50, and the oil is discharged through the first oil drain pipe 61 after being catalyzed by the molecular sieve in the molecular sieve column 30. After the molecular sieve column 30 catalyzes the unit time, the removal device 40 removes the second column 32 from the first column 31, and the liquid guiding device 50 guides the oil in the mixing chamber 11 into the second column 32. The molecular sieve in the second column 32 catalyzes the oil, and the catalyzed oil is discharged through the second oil drain pipe 62.

Taking the working of the first oil drain pipe 61 as an example, the oil discharged from the molecular sieve column 30 enters the collecting ring 611 through the collecting bucket 612, and is finally discharged through the oil drain pipe 613. The oil discharged from the oil drain pipe 613 can be directly discharged through the magnetic control valve or enter the oil circulation component 63 through the magnetic control valve.

[0052] Furthermore, when the oil circulation component 63 is working, the circulation pump 631 and the solenoid valve 632 are turned on, and the oil discharged through the oil discharge pipe 613 enters the mixing chamber 11 through the downstream pipeline driven by the circulation pump 631;

[0056] Furthermore, when the connecting rod translation component 41 is working, the execution end of the power cylinder 414 can drive the lifting ring 415 to lift, and the lifting ring 415 drives the second annular frame 416 to lift.

[0072] The electrical components in the present invention are all triggered to operate by the PLC controller;

[0073] When processing gear oil, the oil and hydrogen are added to the mixing chamber 11 in proportion, and the agitator in the mixing chamber 11 stirs the oil. At the same time, the temperature module and the pressure module in the tank body 10 adjust the temperature and pressure in the mixing chamber 11.

[0074] After the mixing is completed, the oil in the mixing chamber 11 is introduced into the molecular sieve column 30 through the liquid guiding device 50, and the oil is discharged through the first oil drain pipe 61 after being catalyzed by the molecular sieve in the molecular sieve column 30. After the molecular sieve column 30 catalyzes the unit time, the removal device 40 removes the second column 32 from the first column 31, and the liquid guiding device 50 guides the oil in the mixing chamber 11 into the second column 32. The molecular sieve in the second column 32 catalyzes the oil, and the catalyzed oil is discharged through the second oil drain pipe 62. The oil discharged through the first oil drain pipe 61 or the second oil drain pipe 62 can be returned to the mixing chamber 11 through the oil circulation component 63 for repeated catalysis. During the oil catalysis process, the temperature module and the pressure module adjust the temperature and pressure in the catalytic chamber 12;

[0075] After the second column 32 catalyzes the unit time, the removal device 40 moves the second column 32 into the first column 31, and the self-lifting molecular sieve replacement device 20 moves the molecular sieve column 30 out of the tank 10, so that the molecular sieve column 30 can be disassembled and replaced, so as to regenerate the inactivated molecular sieve in the molecular sieve column 30;

[0076] When the oil drain device 60 is working, the oil catalyzed by the molecular sieve column 30 is discharged through the first oil drain pipe 61, and the oil catalyzed by the second column 32 is discharged through the second oil drain pipe 62. The second oil drain pipe 62 has the same structure as the first oil drain pipe 61. Taking the working of the first oil drain pipe 61 as an example, the oil discharged from the molecular sieve column 30 enters the collecting ring 611 through the collecting bucket 612, and is finally discharged through the oil drain pipe 613. The oil discharged from the oil drain pipe 613 can be directly discharged through the magnetic control valve or enter the oil circulation component 63 through the magnetic control valve.

[0077] When the oil circulation component 63 is working, the circulation pump 631 and the electromagnetic valve 632 are opened, and the oil discharged through the oil discharge pipe 613 enters the mixing chamber 11 through the downward pipeline driven by the circulation pump 631;

[0078] When the self-lifting molecular sieve replacement device 20 is working, the execution end of the telescopic cylinder 22 drives the sealing plate 23 to descend until the molecular sieve column 30 is moved out of the catalytic chamber 12. At this time, the positioning ring frame 25 on the positioning column 24 can be removed to realize the removal and replacement of the molecular sieve column 30;

[0079] When the removal device 40 is working, the execution end of the connecting rod translation component 41 drives the automatic connection component 42 to move. After the automatic connection component 42 is magnetically connected with the extension ear 321, the connecting rod translation component 41 can drive the second column 32 to move.

[0080] When the connecting rod translation component 41 is working, the execution end of the power cylinder 414 can drive the lifting ring 415 to move up and down, and the lifting ring 415 drives the second annular frame 416 to move up and down. During the lifting and lowering process of the second annular frame 416, the sliding rod 418 at one end of the transmission rod 417 slides in the second annular frame 416 and drives the transmission rod 417 to rotate. During the rotation of the transmission rod 417, the sliding rod 418 at the other end of the transmission rod 417 slides in the first annular frame 413 and drives the moving rod 412 to move in the C-shaped slideway 411 through the first annular frame 413;

[0081] When the connecting rod translation component 41 moves the second column 32, the extension ear 321 is inserted into the card box tube 4111, indicating that the movement of the second column 32 is completed;

[0082] When the automatic connection component 42 is working, the guide plate 421 guides into the extension ear 321. After reaching the designated position, the first electromagnetic block 422 is connected to the extension ear 321 through electromagnetic attraction to achieve connection. The first electromagnetic block 422 can be separated after the power is turned off and the magnetic attraction is cancelled.

[0083] When the liquid guiding device 50 is working, the execution end of the magnetic lifting component 57 drives the lifting plate 51 to move up and down, so that the first clamping tube 52 clamps the molecular sieve column 30 or the second clamping tube 53 clamps the second column 32;

[0084] After the flow control and delivery component 56 on the first connecting ring 54 is opened, the oil can enter the molecular sieve column 30 through the first connecting ring 54 and the first clamping tube 52;

[0085] After the flow control and delivery component 56 on the second communication ring 55 is opened, the oil can enter the second column 32 through the second communication ring 55 and the second clamping tube 53;

[0086] When the flow control and delivery component 56 is working, the controller receives the oil flow information measured by the flow sensor 563, and triggers the electric control valve 562 according to the flow information, so that the oil in the mixing chamber 11 can be delivered through the delivery pipe 561;

[0087] When the magnetic lifting component 57 is working, taking the descending of the lifting plate 51 as an example, the second electromagnetic block 574 located at the upper part of the lifting plate 51 is energized to generate a repulsive force of the same polarity as the magnetic block 573, so that the sliding plate 572 moves downward, and the second electromagnetic block 574 located at the lower part of the lifting plate 51 is energized to generate an attractive force of the opposite polarity to the magnetic block 573, so that the sliding plate 572 moves downward, and the sliding plate 572 drives the lifting plate 51 to descend.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
