Description

Technical Field

[0001] The invention relates to the technical field of mechanical seal devices, and in particular to a mechanical seal device for a self-lubricating reactor. Background Art

[0002] As we all know, during the operation of the reactor, it is very important to ensure its sealing, otherwise it may cause leakage of reaction materials, which will not only cause economic losses, but also may cause safety accidents and environmental pollution. Mechanical seals are commonly used sealing devices for reactors, and their performance directly affects the sealing effect and operating stability of the reactor. When traditional mechanical seals are working, due to the heat and wear generated by friction, external lubricating oil is often required to reduce friction and wear.

[0003] However, existing mechanical seals, such as mechanical seal bearings, have some deficiencies in terms of lubrication. On the one hand, most existing mechanical seal bearings and other mechanical seals adopt a fixed lubrication method, and cannot flexibly adjust the supply of lubricating oil according to the actual working conditions of the reactor (such as workload, temperature, speed, etc.); this may lead to insufficient supply of lubricating oil under certain working conditions, thereby aggravating the wear of the seal and shortening its service life; while under other working conditions, excessive supply of lubricating oil not only causes waste, but also may increase the risk of leakage.

[0004] On the other hand, existing mechanical seals such as mechanical seal bearings usually require manual regular lubrication, which not only increases labor costs, but also makes it difficult to ensure the timeliness and accuracy of lubrication. If the lubrication is not added in time, the sealing effect may be affected; if the lubrication is added excessively, it may cause lubrication leakage.

[0005] Therefore, in order to improve the sealing performance of mechanical seals for reactors, extend their service life, reduce maintenance costs, and adapt to complex and changeable working environments, it is necessary to improve and innovate existing mechanical seals and develop a self-lubricating mechanical seal device for reactors that has a self-lubricating function and can add and regulate the amount of lubricating oil by itself.

The right end of a rotating connecting rod 711 is rotatably connected to the movable block 705 through an adapter 713, and the left end of a second rotating connecting rod 712 is rotatably connected to the side wall of the mounting cavity 704; a stepper motor 714 is fixedly installed on the left inner wall of the linkage box 709, and a worm 715 is fixedly connected to the output shaft of the stepper motor 714, and a worm 715 is meshed with a worm wheel 716, and a screw 717 is fixedly sleeved on the worm wheel 716, and the screw 717 is rotatably installed in the linkage box 709 through a supporting bearing; a threaded groove 718 is provided at one end of the two driving columns 710 that are close to each other, and the top and bottom ends of the screw 717 are threadedly connected to the two threaded grooves 718 respectively.

[0042] Among them, the middle upper part and the middle lower part of the screw rod 717 are both provided with external threads, and the thread directions of the two external threads on the screw rod 717 are arranged in opposite directions; the right side of the linkage box 709 is fixedly connected with a guide sleeve 719, and a guide rod 720 is movably sleeved in the guide sleeve 719 along the horizontal direction, and the right end of the guide rod 720 is fixedly connected to the adapter 713; a spring 721 is fixedly connected between the left end of the guide rod 720 and the left inner wall of the guide sleeve 719.

[0043] In this embodiment, an oil supply penetration cotton core 707 for penetrating the lubricating oil downward is fixedly provided in the oil supply channel 703 located on the upper and lower sides of the oil quantity adjusting column 706; a sealing sleeve 708 is provided on the left inner wall of the oil supply channel 703, and the oil quantity adjusting column 706 seals and slides through the sealing sleeve 708.

[0044] Furthermore, a guide slider 722 is provided at the bottom of the movable block 705, and a first slide rail is provided on the bottom inner wall of the installation cavity 704. The guide slider 722 is slidably installed on the first slide rail along the horizontal direction; a slide rod 723 is fixedly connected to the right side of the driving column 710, and a second slide rail is provided on the right inner wall of the linkage box 709, and the right end of the slide rod 723 is slidably installed on the second slide rail along the vertical direction.

[0045] The controller 801 is electrically controlled and connected to the stirring motor 4 , the rotation speed sensor 901 , the pressure sensor 902 , the temperature sensor 903 and the stepping motor 714 , respectively.

[0046] like Figure 1-8 In the present invention, a self-lubricating and refueling unit is provided, and the self-lubricating and refueling unit includes a sensor module 9, a control module 8 and an oil supply module 7. The sensor module 9 monitors the working parameters of the reactor 1 in real time, such as the rotation speed, temperature, pressure, etc.; the control module 8 receives the data transmitted by the sensor module 9, and analyzes and processes it based on a preset algorithm to calculate the required amount of lubricating oil; the oil supply module 7 accurately provides an appropriate amount of lubricating oil to the seal (such as the mechanical seal bearing 6 in the present invention) according to the instructions of the control module 8. For example, when the rotation speed of the reactor 7 suddenly increases or the temperature rises, the speed sensor 901, the pressure sensor 902 and the temperature sensor 903 in the sensor module 9 will immediately detect these changes and transmit the data to the controller 801 in the control module 8; the controller 801 in the control module 8 responds quickly and increases the oil supply of the oil supply module 7 to the mechanical seal bearing 6 to ensure that the mechanical seal bearing 6 and other seals can still maintain good lubrication under high load conditions.

[0047] The present invention provides an adaptively adjustable oil supply channel structure so that the oil supply channel 703 can adaptively adjust the distribution and oil supply amount of the lubricating oil according to different working conditions; the oil supply channel 703 adopts an adjustable aperture structure, when under low load conditions, the oil supply aperture of the oil supply channel 703 can be reduced; and under high load conditions, the aperture of the oil supply channel 703 can be enlarged to ensure that the lubricating oil can be adaptively adjusted to provide sufficient lubrication protection for mechanical seals such as the mechanical seal bearing 6.

[0048] As a further specific implementation, an oil supply adjustment component is provided in the above-mentioned oil supply module 7. When the oil supply module 7 needs to adjust the oil supply amount of the mechanical seal bearing 6, the stepper motor 714 is used to drive the worm 715 to rotate forward or reverse. When the worm 715 rotates, it meshes with the worm wheel 716 for transmission. The worm wheel 716 also drives the screw 717 to rotate. Since the thread directions of the two external threads on the screw 717 are arranged in opposite directions, when the screw 717 rotates, the two driving columns 710 can each pass through the thread groove 718 on the screw 717. The two external threads are used for thread transmission that approaches or moves away from each other; when the two driving columns 710 move away from each other, the linkage box 709 and the driving column 710 can be coordinated with the first rotating link 711 and the second rotating link 712, so that the adapter 713, the movable block 705, the linkage box 709 and the driving column 710 can be moved to the left as a whole, and the movable block 705 also drives the oil quantity adjustment column 706 to move to the left, and then the oil supply of the oil supply channel 703 is adjusted by adjusting the leftward movement of the oil quantity adjustment column 706. On the contrary, when the oil quantity adjusting column 706 is adjusted to the right, the oil supply quantity of the oil supply channel 703 can be reduced; and after the adjustment, the guide sleeve 719 will also follow the linkage box 709 to move left and right, and cause the spring 721 in the guide sleeve 719 to be stretched or squeezed, so that after the adjustment, the spring 721 will produce an elastic reaction, which can make the linkage box 709 and the driving column 710 produce an elastic effect, which is conducive to promoting the threaded groove 718 on the driving column 710 The threads are more tightly engaged with the screw rod 717, ensuring that the threads are not prone to stripping after adjustment. Ultimately, the oil quantity adjustment column 706 can be more stable in the oil supply channel 703 after adjustment, ensuring that the oil supply in the oil supply channel 703 is more stable after adjustment, thereby ensuring that the subsequent lubrication is more stable and the use effect is better. Ultimately, this not only makes it possible to add and control the amount of lubricating oil according to the real-time working conditions of the reactor, but also the adjusted oil supply is very stable, which greatly improves the sealing performance and service life of seals such as the mechanical seal bearing 6.

[0049] In summary, through the above structural improvements, the mechanical seal device for the self-lubricating reactor can better adapt to the complex and changeable working environment of the reactor, realize precise control and adaptive adjustment of the amount of lubricating oil, greatly improve the sealing performance and reliability, reduce maintenance costs, and extend service life.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
