Description

Technical Field

[0001] This invention relates to the field of vacuum emulsifier technology, specifically to an intelligent proportioning and mixing device for a vacuum emulsifier. Background Technology

[0002] Vacuum emulsification equipment is widely used in the proportioning, mixing, and homogenization emulsification processes of materials such as cosmetics, pharmaceutical ointments, fine chemical emulsions, and food sauces. The vacuum sealed environment is the core condition for ensuring the quality of the emulsified finished product: stable negative pressure can remove the tiny air bubbles trapped inside the material during the mixing and homogenization process, while isolating oxygen to prevent the oxidation and deterioration of oils and functional active raw materials, ensuring that the dispersed phase and the continuous phase fully collide and fuse, improving the uniformity of emulsion mixing and long-term storage stability, and reducing defects such as product stratification, demulsification, and coarse particles.

[0003] Current intelligent proportioning and mixing devices in vacuum emulsifiers generally use flanges and gaskets to achieve detachable sealing connections between the vacuum pump and vacuum pipeline and the main emulsification tank. The entire vacuum system relies on the vacuum pump to continuously pump and maintain the negative pressure inside the emulsification tank. During long-term continuous production, the sealing gaskets of the flange sealing structure are prone to sealing failure, forming tiny leakage channels. During the vacuuming operation, the outside atmosphere will continuously seep into the vacuum pipeline through the flange gaps and enter the main emulsification tank. The negative pressure fluctuates frequently, disrupting the stable negative pressure defoaming environment. The tiny bubbles trapped inside the material cannot fully expand, rupture, and be extracted by the vacuum pump under the preset negative pressure conditions. A large number of microbubbles remain inside the material system for a long time, ultimately leading to insufficient material proportioning and mixing, and uneven emulsion particle size distribution.

[0004] To address the above issues, an intelligent proportioning and mixing device for a vacuum emulsifier is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent proportioning and mixing device for a vacuum emulsifier. By using this device, the problem mentioned above can be solved: during long-term continuous production, the sealing gasket of the flange sealing structure is prone to sealing failure, which ultimately leads to insufficient material proportioning and mixing and uneven emulsion particle size distribution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The intelligent proportioning and mixing device of the vacuum emulsifier includes a frame and a lifting component fixed inside the frame. A stirring component is installed at one end of the lifting component. An emulsification tank is installed inside the frame, and the stirring component is connected to the emulsification tank. A proportioning and feeding component is also installed inside the frame, with one end connected to the stirring component. A first flange is provided on one side of the stirring component, and a second flange is installed at one end of the first flange. A detection component is installed on the surface of the second flange, and the detection component is in contact with the first flange. A Y-shaped telescopic hose is connected to one end of the second flange. A vacuum pump is correspondingly installed on one side of the frame, and the Y-shaped hose... The flexible hose is connected to the vacuum pump. A first solenoid valve is correspondingly installed on the surface of the Y-shaped flexible hose. By switching the opening and closing state of the corresponding first solenoid valve, another vacuum pump can be activated to continuously provide negative pressure suction power. An annular plate is fixedly installed inside the second flange. An electromagnet is installed inside the annular plate. An annular sealing element is slidably engaged inside the annular plate. An annular sealing plate is fixedly installed inside the first flange. When the detection element detects that the seal between the first flange and the second flange has failed, the electromagnet outputs a repulsive thrust, causing the annular sealing element to insert into the annular sealing plate to create a new independent flow channel.

[0007] Furthermore, the detection element includes a circular frame and several ultrasonic leakage sensors fixed inside the circular frame, and the circular frame is fixedly connected to the second flange.

[0008] Furthermore, a number of first springs are correspondingly provided inside the annular plate. An arc-shaped block is fixedly installed at one end of each first spring. The arc-shaped block is slidably connected to the inside of the annular plate and is engaged with the annular sealing component.

[0009] Furthermore, the annular sealing component includes an annular sealing plate and an annular magnet block fixed to one side of the annular sealing plate. The annular sealing plate is slidably connected to the inside of the annular plate, and the annular sealing plate is engaged with the arc surface block.

[0010] Furthermore, the annular sealing plate has several through holes on one side, and a horizontal plate is fixedly installed inside the through holes. A push rod is fixedly installed on one side of the horizontal plate.

[0011] Furthermore, a sealing airbag is provided on the outer periphery of the annular sealing plate.

[0012] Furthermore, the annular sealing plate has several air storage chambers inside, and the air storage chambers are connected to the sealing airbags; The annular sealing plate is provided with several extrusion components for squeezing the gas inside the gas storage chamber into the sealing airbag; The extrusion component includes a first cylinder and an elastic telescopic tube fixed to one end of the first cylinder. The first cylinder is fixedly connected to the interior of an annular sealing plate, and the elastic telescopic tube is in contact with the interior of the annular sealing plate. A second cylinder is fixedly installed at one end of the elastic telescopic tube and is slidably connected to the interior of the annular sealing plate. The first cylinder, the second cylinder, and the elastic telescopic tube are interconnected. A sealing block is fixedly installed inside the second cylinder, and a piston plate is fixedly installed on the surface of the second cylinder and is slidably connected to the air storage chamber. Several air inlet pipes are provided inside the annular sealing plate, and each air inlet pipe corresponds to one of the second cylinders. The air inlet pipes are slidably connected to the annular plate and the second flange, respectively. A retaining ring is fixedly installed inside the first cylinder, and a limit rod is fixedly installed on one side of the retaining ring. A sealing disc is slidably connected to the surface of the limit rod, and a push rod is in contact with the sealing disc. A second spring is sleeved on the surface of the limit rod, and one end of the second spring is fixedly connected to the sealing disc, and the other end of the second spring is fixedly connected to the limit rod.

[0013] Furthermore, the lifting component includes a fixed frame and a first motor fixed to one end of the fixed frame. The fixed frame is fixedly connected to the frame. A threaded rod is rotatably connected inside the fixed frame. The threaded rod is fixedly connected to the output end of the first motor. A support frame is rolledly connected to the surface of the fixed frame, and the support frame is threadedly connected to the threaded rod.

[0014] Furthermore, the stirring component includes a sealing cap and a second motor fixed to one side of the sealing cap. The sealing cap is fixedly connected to the support frame and contacts the emulsification tank. A stirring rod is rotatably connected to one side of the sealing cap and is fixedly connected to the output end of the second motor.

[0015] Furthermore, the proportioning and feeding component includes a proportioning box and a metering sensor disposed on one side of the proportioning box. The proportioning box is fixedly connected to the frame. A discharge pipe is connected to one side of the proportioning box and is connected to a sealing cover. A second solenoid valve is disposed on the surface of the discharge pipe. The metering sensor and the second solenoid valve are electrically connected through a controller.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. A closed-loop intelligent feeding control system is set up with a proportioning and feeding component. Relying on the coordinated operation of metering sensors, controllers, and a second solenoid valve, it realizes intelligent quantitative proportioning and feeding of multi-component materials, eliminates manual proportioning errors, ensures consistent emulsion raw material proportions in different production batches, and improves the stability of finished products.

[0017] 2. Equipped with a surround detection element, multiple ultrasonic leak sensors enable online monitoring of the first and second flanges, allowing for early identification of micro-leakage in both flanges. This overcomes the shortcomings of traditional manual periodic leak detection, which suffers from missed detections and delays, and helps prevent material waste caused by leaks.

[0018] 3. When the flange seal fails, the controller will activate the electromagnet to quickly drive the annular sealing component to automatically create an independent flow channel to isolate the leakage gap. This eliminates the need to shut down the entire machine to disassemble and replace the gasket, maintains a stable vacuum inside the emulsification tank, ensures the continuous mixing and emulsification process, and reduces raw material loss.

[0019] 4. The annular sealing plate is equipped with sealing airbags on its outer periphery, which, together with the rigid plug-in partition, form a double-layer sealing and protection structure. The sealing airbags are autonomously inflated by the pipeline pressure difference. The airbags can adaptively fill the assembly tolerance gaps to achieve flexible sealing, effectively blocking micro-leakage and further improving the reliability of vacuum isolation.

[0020] 5. A redundant vacuum power circuit is formed by using a Y-type telescopic hose, dual vacuum pumps, and a first solenoid valve. In the event of a failure of a single vacuum pump, a backup pump can be switched online to continuously provide negative pressure without the need for pressure relief and shutdown for maintenance, ensuring continuous operation of the production line and improving production capacity.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1 and Figure 2 As shown, the intelligent proportioning and mixing device of the vacuum emulsifier includes a frame 1 and a lifting component 2 fixed inside the frame 1. A stirring component 3 is provided at one end of the lifting component 2. An emulsification tank 4 is installed inside the frame 1. The lifting component 2 drives the stirring component 3 to lift and open, so as to reliably seal the emulsification tank 4 and provide a basic sealing guarantee for building a stable vacuum emulsification environment inside the tank. The stirring component 3 is connected to the emulsification tank 4. The stirring component 3 works with the emulsification tank 4 to complete the shearing and stirring of materials in a closed environment, so as to achieve basic mixing of multi-component materials and meet the basic process requirements for emulsion homogenization preparation.

[0025] like Figure 3As shown, the lifting component 2 includes a fixed frame 21 and a first motor 22 fixed to one end of the fixed frame 21. The fixed frame 21 is fixedly connected to the frame 1. A threaded rod 23 is rotatably connected inside the fixed frame 21. The threaded rod 23 is fixedly connected to the output end of the first motor 22. A support frame 24 is rolledly connected to the surface of the fixed frame 21, and the support frame 24 is threadedly connected to the threaded rod 23. The controller drives the first motor 22 to rotate in the forward direction. The first motor 22 drives the threaded rod 23 to rotate synchronously. By relying on the threaded pair transmission, the rotational motion of the threaded rod 23 is converted into the linear displacement of the support frame 24 along the axial direction of the fixed frame 21. The support frame 24 drives the stirring component 3 to be lifted, so that the stirring component 3 is separated from the mouth of the emulsification tank 4, and raw materials can be put into the emulsification tank 4. The stirring component 3 includes a sealing cover 31 and a second motor 32 fixed to one side of the sealing cover 31. The sealing cover 31 is fixedly connected to the support frame 24 and is in contact with the emulsification tank 4. A stirring rod 33 is rotatably connected to one side of the sealing cover 31. The stirring rod 33 is fixedly connected to the output end of the second motor 32. The output torque of the second motor 32 drives the stirring rod 33 to rotate continuously, stirring, mixing, shearing and dispersing the oil phase, water phase and various functional auxiliary materials added inside the emulsification tank 4. Under the vacuum negative pressure combined with stirring and shearing action, the tiny bubbles inside the material are precipitated and removed, and the components are fully collided and fused to complete homogenization and emulsification, thus preparing a milky material with uniform and stable particle size. The proportioning and feeding component 5 includes a proportioning box 51 and a metering sensor 52 installed on one side of the proportioning box 51. The proportioning box 51 is fixedly connected to the frame 1. A discharge pipe 53 is connected to one side of the proportioning box 51 and is connected to the sealing cover 31. A second solenoid valve 54 is installed on the surface of the discharge pipe 53. The metering sensor 52 and the second solenoid valve 54 are electrically connected through the controller. When the equipment is working, the operator enters the standard proportioning parameters of the water phase, oil phase and functional auxiliary materials and the total amount of material added at one time into the controller in advance. During the production process, the controller issues a feeding command and opens the second solenoid valve 54. The material inside the proportioning box 51 is conveyed to the emulsification tank 4 in a closed manner through the discharge pipe 53. Throughout the material conveying process, the metering sensor 52 dynamically collects the instantaneous flow rate and cumulative feeding amount of the material in real time and feeds the collected analog signal back to the controller in real time. The controller continuously compares the real-time feeding data with the preset standard proportioning data and intelligently corrects the feeding rhythm. When the cumulative feeding amount is about to reach the process set threshold, the controller intelligently adjusts the opening of the second solenoid valve 54, switching from the fully open state to the small flow precise feeding state to prevent overfeeding. When the feeding data accurately matches the preset ratio parameters, the controller immediately and automatically closes the second solenoid valve 54, precisely terminating the feeding process. The entire feeding process does not require manual operation, manual weighing, or manual valve opening and closing. Relying on the closed-loop logic of real-time sensor feedback and intelligent calculation by the controller, it realizes quantitative, proportional, precise, and automated feeding of multi-component materials, and completes intelligent mixing operations in conjunction with subsequent stirring and vacuum emulsification processes.

[0026] To address the technical problem that sealing gaskets are prone to sealing failure during long-term continuous production of flange sealing structures, ultimately leading to insufficient material mixing and uneven emulsion particle size distribution, the following preferred technical solution is provided: like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the frame 1 is also equipped with a proportioning and feeding component 5. The proportioning and feeding component 5 can realize intelligent quantitative feeding of auxiliary materials, reduce the error of manual feeding and proportioning, and ensure the consistency of product batch proportioning. One end of the proportioning and feeding component 5 is connected to the agitator 3. The material is conveyed to the emulsification tank 4 in a closed manner through the agitator 3. The feeding does not require opening the tank, reducing the entry of outside air and oxygen into the tank and reducing the risk of raw material oxidation. A first flange 6 is provided on one side of the agitator 3, and a second flange 7 is installed at one end of the first flange 6. The first flange 6 and the second flange 7 are connected by bolts to form a detachable pipeline joint. It facilitates the disassembly, cleaning, inspection, and maintenance of vacuum pipelines, and is compatible with pharmaceutical clean production standards. The surface of the second flange 7 is equipped with a detection element 8, which is in contact with the first flange 6. The detection element 8 is arranged close to the joint between the first flange 6 and the second flange 7, allowing for close-range acquisition of leakage signals. This provides higher sensitivity for detecting micro-leakage in the first flange 6 and the second flange 7, enabling the identification of faults in the early stages of leakage. It also enables online real-time monitoring of the sealing status of the first flange 6 and the second flange 7, which is different from traditional manual periodic leak detection, reducing the problem of missed detections and preventing product quality defects caused by leaks in advance. A Y-type telescopic hose 9 is connected to one end of the second flange 7. The Y-type telescopic hose 9 has telescopic buffering performance. A vacuum pump 10 is installed on one side of the frame 1, and the Y-type telescopic hose 9 is connected to the vacuum pump 10. A first solenoid valve 20 is installed on the surface of the Y-type telescopic hose 9. The dual vacuum pumps 10 and the branch first solenoid valve 20 form a redundant vacuum power system. When a single vacuum pump 10 fails, the backup pump can be switched online without stopping the machine for depressurization and maintenance, ensuring continuous operation of the production line. The other vacuum pump 10 can be started continuously by switching the opening and closing state of the corresponding first solenoid valve 20. The system provides negative pressure suction power. An annular plate 30 is fixedly installed inside the second flange 7. An electromagnet 40 is installed inside the annular plate 30. The electromagnet 40 is electrically connected to the detection element 8 through a controller. The controller is existing technology and is not shown in the figure. An annular sealing element 50 is slidably engaged inside the annular plate 30. An annular sealing plate 60 is fixedly installed inside the first flange 6. When the detection element 8 detects that the seal between the first flange 6 and the second flange 7 has failed, the electromagnet 40 outputs a repulsive thrust, causing the annular sealing element 50 to insert into the annular sealing plate 60 to create a new independent flow channel. After the raw materials are put into the emulsification tank 4, the lifting component 2 drives the stirring component 3 to descend and seal the emulsification tank 4. The proportioning and feeding component 5 completes the intelligent proportioning and conveying of materials according to the process setting. The materials enter the emulsification tank 4 through the stirring component 3. The vacuum pump 10 draws air from the inside of the emulsification tank 4 through the Y-type telescopic hose 9, the first flange 6, and the second flange 7, so that a stable negative pressure environment is formed inside the emulsification tank 4. Under the combined action of vacuum negative pressure and shearing and stirring of the stirring component 3, the tiny bubbles inside the material expand, precipitate and are extracted, reducing the surface tension of the dispersed phase droplets, promoting the full collision and shearing dispersion of different components such as oil phase and water phase, completing homogeneous emulsification, and preparing an emulsion product with uniform particle size and stable system. The detection element 8, installed at the mating position of the first flange 6 and the second flange 7, continuously collects the flange sealing status signal online and transmits it to the controller in real time. When the first flange 6 and the second flange 7 experience gasket aging and sealing failure due to long-term use, and there is a risk of external atmospheric infiltration, the controller receives the leakage signal and triggers the protection action. The electromagnet 40 in the second flange 7 generates a repulsive force, pushing the annular sealing element 50, which is slidably engaged inside the annular plate 30, to slide axially until the annular sealing element 50 is inserted into the annular sealing plate 60 built into the first flange 6 and forms a snap-fit ​​again. After being inserted into place, the annular plate 30, the annular sealing element 50, and the annular sealing plate 60 cooperate to form an independent flow channel, physically isolating the original leakage mating area of ​​the first flange 6 and the second flange 7, preventing external atmospheric air from seeping into the vacuum pipeline and the interior of the emulsification tank 4 through the gap between the first flange 6 and the second flange 7, maintaining the stable vacuum level inside the emulsification tank 4, and ensuring the continuous operation of the emulsification process. The two branch lines of the Y-type telescopic hose 9 are each equipped with a first solenoid valve 20, which independently controls the on / off state of each vacuum pump 10 branch. Under normal working conditions, any vacuum pump 10 can be used to provide negative pressure. If the operating vacuum pump 10 fails and stops, the controller switches the opening and closing state of the two first solenoid valves 20, closes the branch corresponding to the failed vacuum pump 10, connects the branch of the standby vacuum pump 10, and starts another vacuum pump 10 to continuously pump vacuum. There is no need to shut down the whole machine for depressurization and maintenance, ensuring uninterrupted operation of mixing and emulsification. Therefore, the sealing status of the first flange 6 and the second flange 7 is monitored in real time by the detection component 8. Once the sealing failure of the first flange 6 and the second flange 7 is detected, the electromagnet 40 can be linked to drive the annular sealing component 50 to act quickly, build a new flow channel to isolate the leakage location, and block the infiltration of outside air into the emulsification tank 4 in a timely manner, so as to avoid the vacuum fluctuation in the emulsification tank 4 and improve the mixing effect. A backup vacuum circuit is formed by using a Y-type telescopic hose 9 with a vacuum pump 10 and a branch first solenoid valve 20. When a single vacuum pump 10 fails, the backup pump can be switched online to continue operation without interrupting the emulsification process, which greatly shortens the equipment downtime for maintenance and is suitable for the large-scale continuous production of cosmetics, ointments and other products, thereby improving the overall capacity of the production line.

[0027] like Figure 4As shown, the detection component 8 includes a circular frame 81 and several ultrasonic leakage sensors 82 fixed inside the circular frame 81. The circular frame 81 is fixedly connected to the second flange 7. During normal vacuuming operations, multiple sets of ultrasonic leakage sensors 82 continuously collect acoustic signals at the joint of the first flange 6 and the second flange 7. When the sealing gasket between the first flange 6 and the second flange 7 ages and fails to seal, resulting in a leakage gap, the outside atmosphere seeps in from the gap under the action of negative pressure differential. The airflow forms turbulence at the flange joint and generates characteristic high-frequency ultrasonic waves. The circumferentially arranged ultrasonic leakage sensors 82 can capture this turbulent ultrasonic signal and convert the collected mechanical vibration signal into an electrical signal and transmit it to the matching controller.

[0028] like Figure 5 and Figure 8 As shown, several first springs 301 are correspondingly arranged inside the annular plate 30. An arc-shaped block 302 is fixedly installed at one end of the first spring 301. The arc-shaped block 302 is slidably connected to the inside of the annular plate 30 and is engaged with the annular sealing member 50. When multiple sets of ultrasonic leakage sensors 82 detect that the sealing of the first flange 6 and the second flange 7 has failed, the controller drives the electromagnet 40 to output a repulsive force, pushing the annular sealing member 50 axially toward the annular sealing plate 60. During the displacement of the annular sealing member 50, the outer wall of the annular sealing member 50 presses against the arc-shaped guide surface of the arc-shaped block 302. The arc-shaped block 302 is forced to overcome the elastic force of the first spring 301 and retracts outward, so that the upper arc of the annular sealing member 50 is engaged with the initial engagement position. After the face blocks 302 separate from each other, the annular sealing member 50 continues to move to the sealing position. Then, the first spring 301 rebounds, causing the lower corresponding arc face block 302 to slide inward and lock into the new positioning slot of the annular sealing member 50. This completes the locking and fixing of the sealing position of the annular sealing member 50, maintains the sealing state, and ensures that the annular sealing member 50 is stably inserted into the annular sealing plate 60, continuously isolating the flange leakage channel. After the equipment is shut down for maintenance and the fault is eliminated, the electromagnet 40 can be controlled to generate an attraction force, and the annular sealing member 50 will retract to the initial position, squeezing the arc face block 302 again to retract until the return is completed. Then, under the action of the first spring 301, the arc face block 302 re-locks and fixes the annular sealing member 50, restoring the standby state.

[0029] like Figure 5 , Figure 8 and Figure 9As shown, the annular sealing component 50 includes an annular sealing plate 501 and an annular magnet block 502 fixed to one side of the annular sealing plate 501. The annular sealing plate 501 is slidably connected to the inside of the annular plate 30. The annular sealing plate 501 is engaged with the arc surface block 302. The electromagnet 40 generates a magnetic repulsive force acting on the annular magnet block 502. The annular magnet block 502 bears the electromagnetic repulsive force, driving the annular sealing plate 501 to slide axially along the inside of the annular plate 30. During the sliding process, the annular sealing plate 501 squeezes the arc surface block 302. The arc surface block 302 is compressed by the spring and retracts, releasing the original engagement limit until the annular sealing plate 501 moves to the sealing position and is inserted into the annular sealing plate 60. Under the reset elastic force of the first spring 301, the arc surface block 302 engages with the annular sealing plate 501 again, realizing the mechanical locking of the sealing position of the annular sealing plate 501, constructing an independent flow channel to isolate the leakage areas of the first flange 6 and the second flange 7, and blocking the infiltration of external atmosphere into the vacuum pipeline.

[0030] To address the technical problem of secondary leakage caused by wear between the annular sealing plate 501 and the annular sealing plate 60 during prolonged use, the following preferred technical solution is provided: like Figure 8 and Figure 10 As shown, a number of through holes 601 are provided through one side of the annular sealing plate 60. A horizontal plate 602 is fixedly installed inside the through holes 601. A push rod 603 is fixedly installed on one side of the horizontal plate 602. A sealing airbag 80 is provided on the outer periphery of the annular sealing plate 501. The sealing airbag 80 is assembled on the outer periphery of the annular sealing plate 501. On the basis of the basic mechanical isolation formed by the insertion of the annular sealing plate 501, the sealing airbag 80 is used to achieve flexible sealing, forming a double-layer sealing and protection structure. Compared with a single rigid insertion seal, it can make up for the small gaps caused by the machining tolerance of parts and the assembly gap, and further block the external atmosphere from seeping into the vacuum pipeline and the emulsion tank 4 through the gap. The vacuum sealing isolation effect is better. The sealing airbag 80 has flexible deformation capability and can adaptively fit the irregular gaps on the inner wall of the annular sealing plate 60, avoiding the problem of local poor fit that is easy to occur with rigid fit. It greatly improves the reliability of leakage isolation, effectively prevents micro-leakage, and ensures the continuous stability of the vacuum inside the emulsion tank 4.

[0031] like Figures 8-10 As shown, the annular sealing plate 501 has several gas storage chambers 90 inside, and the gas storage chambers 90 are connected to the sealing airbag 80. The gas storage chambers 90 can store a certain amount of gas in advance, which can prevent the sealing airbag 80 from being over-expanded and damaged, while ensuring that the sealing airbag 80 maintains a suitable expansion pressure, adaptively filling the assembly gap and machining tolerance gap between the annular sealing plate 501 and the annular sealing plate 60, and improving the sealing and isolation effect. The annular sealing plate 501 is internally equipped with several extrusion components 70 for compressing the gas inside the gas storage chamber 90 into the sealing airbag 80. Each extrusion component 70 includes a first cylinder 701 and an elastic telescopic tube 702 fixed to one end of the first cylinder 701. The elastic telescopic tube 702 has an elastic function. The first cylinder 701 is fixedly connected to the interior of the annular sealing plate 501, and the elastic telescopic tube 702 is in contact with the interior of the annular sealing plate 501. A second cylinder 703 is fixedly installed at one end of the elastic telescopic tube 702, and the second cylinder 703 is slidably connected to the interior of the annular sealing plate 501. The first cylinder 701, the second cylinder 703, and the elastic telescopic tube 702 are interconnected. A sealing block 704 is fixedly installed inside the second cylinder 703, and a piston plate 705 is fixedly installed on the surface of the second cylinder 703, with the piston plate 705 in contact with the gas storage chamber 90. The air chamber 90 is slidably connected. The annular sealing plate 501 is provided with several air inlet pipes 706. Each air inlet pipe 706 corresponds to a second cylinder 703. The air inlet pipes 706 are slidably connected to the annular plate 30 and the second flange 7, respectively. A retaining ring 707 is fixedly installed inside the first cylinder 701. A limit rod 708 is fixedly installed on one side of the retaining ring 707. A sealing disc 709 is slidably connected to the surface of the limit rod 708. The push rod 603 is in contact with the sealing disc 709. A second spring 710 is sleeved on the surface of the limit rod 708. The limit rod 708, the sealing disc 709 and the second spring 710 form a normally closed passage structure. In the initial state, the air passage is automatically closed to avoid premature leakage and loss of gas in the air storage chamber 90. The passage is only opened when the sealing action is triggered to ensure long-term storage of gas in the air storage chamber 90. It can be recycled multiple times. One end of the second spring 710 is fixedly connected to the sealing disc 709, and the other end of the second spring 710 is fixedly connected to the limiting rod 708. Under the initial working condition, the second spring 710 continuously applies elastic force to push the sealing disc 709 to press against the retaining ring 707. The flow channel corresponding to the retaining ring 707 is in a closed blocking state. The elastic telescopic tube 702 remains in a naturally extended state. The piston plate 705 stays in the initial position of the gas storage chamber 90. The metered gas inside the gas storage chamber 90 remains stationary. The sealing airbag 80 remains in a deflated and contracted state, without interfering with the normal vacuuming operation of the vacuum pipeline. When the ultrasonic leakage sensor 82 detects the sealing failure of the first flange 6 and the second flange 7, and the electromagnet 40 drives the annular sealing plate 501 to be axially inserted into the annular sealing plate 60, the push rod 603 pushes the sealing disc 709 synchronously. The sealing disc 709 overcomes the elastic force of the second spring 710 and slides along the limiting rod 708. The sealing disc 709 separates from the retaining ring 707, and the inner channel of the retaining ring 707 is opened. The vacuum pump 10 of the emulsion tank 4 continuously draws a vacuum, so that a negative pressure is formed in the inner cavity of the first cylinder 701, the elastic telescopic tube 702 and the second cylinder 703. At the same time, the air inlet pipe 706 connects to the outside. A pressure difference is formed at both ends of 03. The pressure difference drives the second cylinder 703 to slide towards the elastic telescopic tube 702, compressing the elastic telescopic tube 702. During the sliding process, the second cylinder 703 drives the piston plate 705 to move synchronously. The piston plate 705 squeezes the pre-placed gas inside the gas storage chamber 90. The gas inside the gas storage chamber 90 is filled into the sealing airbag 80 through the connecting channel. The sealing airbag 80 expands to complete the flexible secondary seal. Together with the rigid partition of the annular sealing plate 501, a double-layer seal is achieved, blocking the infiltration of external atmosphere into the vacuum pipeline and preventing secondary leakage caused by wear between the annular sealing plate 501 and the annular sealing plate 60 after long-term use. When disassembling and repairing the first flange 6 and the second flange 7, the second flange 7 can be directly separated from the first flange 6. The annular sealing plate 501 is then restored to its initial position by the electromagnet 40 adsorbing it, and the gas inside the sealing airbag 80 is drawn back into the gas storage chamber 90.
