[0012] Preferably, the pressure sensor is electrically connected to the controller, and the alarm is electrically connected to the controller.

[0013] Beneficial effects

[0014] By adopting the sliding seal, rubber ring, sealing rubber strip, pressure sensor, controller and alarm, when the side of the inner tank ruptures, resulting in a rapid increase in pressure between the inner and outer tanks, under the action of pressure, the two rubber rings move in opposite directions through the sliding seal. At the same time, the pressure sensor detects the abnormal change of pressure and immediately sends a signal to the controller. After receiving the signal, the controller quickly analyzes and confirms the rupture event of the inner tank, and then activates the alarm to emit an alarm sound to remind the personnel to take timely remedial measures. When the outer tank ruptures before the personnel have time to operate, the pressure decreases, causing the two rubber rings to move towards the rupture point driven by the sliding seal. At the same time, due to the special shape setting of the rubber ring, it is avoided that the rubber ring deforms and cracks due to friction during the movement. At this time, the sealing rubber strip automatically fills the gap and forms a sealing layer together with the rubber ring to prevent the leakage of materials, giving enough time for the personnel to take remedial measures and effectively reducing the accident losses and risks.

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0022] The specific embodiments of the present utility model will be described below with reference to the drawings. Specific Embodiment 1:

[0024] Referring to Figures 1-4 , an explosion-proof flash evaporation tank includes an outer tank 1. The surface of the sealing cover 5 is provided with a feed pipe 6. Through the setting of the feed pipe 6, the mixture or liquid material to be processed can be safely and stably fed into the inner tank 9 for subsequent flash evaporation treatment. The surface of the sealing cover 5 is provided with an outlet pipe 7. During the flash evaporation process, the low-boiling components are quickly vaporized after heating, discharged through the outlet pipe 7 and collected after being cooled by a condenser. The bottom of the inner tank 9 is provided with a liquid outlet pipe 10, and the liquid outlet pipe 10 penetrates through the outer tank 1 and is connected to the bottom of the inner tank 9. After the flash evaporation process is completed, by opening the valve 8 on the liquid outlet pipe 10, the separated material or residual components can be discharged for subsequent collection, treatment or reuse. Valves 8 are provided on the surfaces of the feed pipe 6, the outlet pipe 7 and the liquid outlet pipe 10. By operating the valve 8, the entry and exit of materials and the discharge of gases can be flexibly controlled to ensure the smooth progress of the flash evaporation process and the safe operation of the equipment. The bottom of the outer tank 1 is provided with support legs 2. The surface of the outer tank 1 is provided with a sealing cover 5. Flanges are provided on the surfaces of the sealing cover 5 and the outer tank 1, and the sealing cover 5 is fixedly connected to the outer tank 1 through the flanges. The main function of the sealing cover 5 is to ensure the sealing performance of the inner tank 9, prevent material leakage and pollution of the internal material by the external environment. The fixed connection with the outer tank 1 through the flanges enhances the stability and safety of the connection, and at the same time facilitates the disassembly of the cracked inner tank 9.

[0025] Inside the outer tank 1, an inner tank 9 is installed. A sliding seal 11 is provided on the surface of the inner tank 9. Through the setting of the sliding seal 11, it allows the rubber ring 13 to smoothly move on the surface of the inner tank 9 when the pressure changes to cope with the situation of the tank body rupture. A fixing seat 12 is provided on the surface of the sliding seal 11. A rubber ring 13 is provided on the side of the fixing seat 12, which is made of a material with high strength, wear resistance and good elasticity. The outer side of the rubber ring 13 is narrower than the inner side to ensure that it will not be easily deformed or cracked due to friction during the movement. These rubber rings 13 are installed at key positions between the inner tank 9 and the outer tank 1 to play a sealing and buffering role. There are two sliding seals 11 and rubber rings 13 arranged in a linear array. The outer side of the rubber ring 13 abuts against the inner wall of the outer tank 1. A sealing strip 15 is provided on the surface of the fixing seat 12. A sealing groove 16 is opened at the bottom of the fixing seat 12. The shape and position of the sealing strip 15 are adapted to the sealing groove 16. When the rubber ring 13 moves to the rupture point, the sealing strip 15 will quickly fill into the sealing groove 16 and closely combine with the rubber ring 13 to form an effective sealing layer to prevent the leakage of the materials in the tank.

[0026] A pressure sensor 14 is provided on the surface of the fixing seat 12 away from the sealing cover 5 to monitor the pressure change between the inner tank 9 and the outer tank 1 in real time. Once an abnormal pressure rise is detected, it indicates that the inner tank 9 may have ruptured. The pressure sensor 14 is embedded at the top of the fixing seat 12 away from the sealing cover 5. A controller 3 is provided on the surface of the outer tank 1 to receive the data from the pressure sensor 14 and perform rapid analysis and processing. When the abnormal pressure is confirmed, the alarm 4 is immediately triggered. An alarm 4 is provided on the surface of the controller 3 to attract the attention of personnel in case of emergency and remind personnel to take remedial measures immediately. The pressure sensor 14 is electrically connected to the controller 3, and the alarm 4 is electrically connected to the controller 3.

[0027] The material enters the interior of the inner tank 9 in a vacuum environment through the feed pipe 6. Due to the sudden decrease in pressure, the boiling point of the liquid decreases accordingly, causing these liquids to separate into liquid and gas under the container pressure. The gas during the flashing process is discharged through the gas outlet pipe 7. Open the valve 8, and discharge the flashed liquid through the liquid outlet pipe 10. When the side of the inner tank 9 ruptures, resulting in a rapid increase in pressure between the inner tank 9 and the outer tank 1, under the action of pressure, the two rubber rings 13 move in the opposite direction through the sliding seal 11. At the same time, the abnormal pressure change is detected through the pressure sensor 14, and a signal is immediately sent to the controller 3. After receiving the signal, the controller 3 quickly analyzes and confirms the rupture event of the inner tank 9, and then activates the alarm 4 to emit an alarm sound to remind the personnel to make timely remedies. When the outer tank 1 ruptures before the personnel have time to operate, the pressure decreases, causing the two rubber rings 13 to move towards the rupture under the drive of the sliding seal 11. At the same time, due to the special shape setting of the rubber rings 13, it is avoided that the rubber rings 13 crack due to deformation caused by friction during the movement. At this time, the sealing rubber strip 15 automatically fills the gap and jointly forms a sealing layer with the rubber rings 13 to prevent the material from leaking out, avoiding damage to the surrounding personnel and equipment, and giving sufficient time for the personnel to make remedies. Specific Embodiment Two:

[0029] On the premise of meeting the above structure, connect the control system to the Internet of Things platform to achieve remote monitoring and real-time data transmission. In this way, even if the personnel are not on site, they can view the pressure status and alarm information of the tank body in real time through mobile devices or computers. At the same time, after detecting the rupture of the inner tank 9, the control system can automatically close the valves 8 of the feed pipe 6 and the liquid outlet pipe 10 to prevent the material from continuing to flow in or out, reducing the leakage amount.

[0030] To sum up:

[0031] 1. By adopting the sliding seal 11, rubber rings 13, sealing rubber strip 15, pressure sensor 14, controller 3 and alarm 4, when the side of the inner tank 9 ruptures, resulting in a rapid increase in pressure between the inner tank 9 and the outer tank 1, under the action of pressure, the two rubber rings 13 move in the opposite direction through the sliding seal 11. At the same time, the abnormal pressure change is detected through the pressure sensor 14, and a signal is immediately sent to the controller 3. After receiving the signal, the controller 3 quickly analyzes and confirms the rupture event of the inner tank 9, and then activates the alarm 4 to emit an alarm sound to remind the personnel to make timely remedies. When the outer tank 1 ruptures before the personnel have time to operate, the pressure decreases, causing the two rubber rings 13 to move towards the rupture under the drive of the sliding seal 11. At the same time, due to the special shape setting of the rubber rings 13, it is avoided that the rubber rings 13 crack due to deformation caused by friction during the movement. At this time, the sealing rubber strip 15 automatically fills the gap and jointly forms a sealing layer with the rubber rings 13 to prevent the material from leaking out,

[0032] giving sufficient time for the personnel to make remedies, effectively reducing the accident losses and risks.
