Technical Field
[0001] This invention belongs to the field of pressure vessel technology, specifically relating to a safety interlock device for pressurized vessels. Background Technology
[0002] A pressure vessel is a sealed container that holds gas or liquid under pressure. Based on working pressure, the hazardous nature of the medium, and its role in production, pressure vessels are classified into three categories. A pressure vessel is a sealed container capable of withstanding pressure. Pressure vessels have extremely wide applications, playing a vital role in many sectors of industry, civil use, military industry, and scientific research. They are most widely used in the chemical and petrochemical industries, primarily for heat transfer, mass transfer, and reaction processes, as well as for storing and transporting pressurized gases or liquefied gases. They also have wide applications in other industrial and civil fields, such as in air compressors. Various specialized compressors and auxiliary equipment for refrigeration compressors (coolers, buffers, oil-water separators, gas tanks, evaporators, liquid coolant tanks, etc.) are all considered pressure vessels.
[0003] Currently, safety interlock devices provide safety guarantees for pressure vessels and ensure their safe operation. However, under high-temperature and high-pressure operations, the safety handles of pressure vessel safety interlock devices are unstable, and the lids are not completely locked, posing a danger. They also cannot guarantee the safe use and production requirements of pressure vessels, resulting in poor work efficiency. Furthermore, when the lid is opened, the high-temperature hot gas that has not been completely discharged from the container overflows from the inlet, posing a burn hazard to nearby operators. In addition, the gas inside the container, if released into the workplace without treatment, can also affect the health of workers and lead to poor environmental performance of the equipment.
[0004] Therefore, a safety interlock device for pressurized containers is needed to solve the safety hazard and environmental problems of hot air overflowing from the inlet of containers that is not completely discharged, which may cause burns to nearby operators. Summary of the Invention

[0027] The present invention will be further described below with reference to embodiments.
[0028] Please see Figure 1-7This invention provides a safety interlock device for a pressurized container, comprising a pressure vessel body 1, a feed inlet pipe 3 fixed to the front of the pressure vessel body 1, a sealing cover 15 disposed in front of a positioning sealing disc 4, a positioning sealing disc 4 disposed at the front end of the feed inlet pipe 3, and an anti-overflow opening mechanism disposed on one side of the positioning sealing disc 4. The anti-overflow opening mechanism includes an annular fixing frame 7, an overflow treatment shell 8, and a pressure relief cotton layer 9. The annular fixing frame 7 is disposed on the surface of the positioning sealing disc 4, and the overflow treatment shell 8 is sleeved and fixed on the outer ring surface of the annular fixing frame 7. A pressure-relief cotton layer 9 is provided between the frame 7 and the overflow treatment shell 8. A waste gas treatment mechanism is provided below the overflow treatment shell 8. The waste gas treatment mechanism includes an overflow discharge pipe 21, an overflow inlet pipe 22, a fan assembly 23, and an activated carbon adsorption device 24. The overflow discharge pipe 21 is located at the lower part of the overflow treatment shell 8, the overflow inlet pipe 22 is located below the overflow discharge pipe 21, the fan assembly 23 is located between the overflow discharge pipe 21 and the overflow inlet pipe 22, and the activated carbon adsorption device 24 is fixed at the end of the overflow inlet pipe 22 away from the fan assembly 23.
[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the annular fixing frame 7 has a fixing sleeve 10 inside. The fixing sleeve 10 of the annular fixing frame 7 is fitted onto the outside of the positioning sealing disc 4, and the inner wall of the annular fixing frame 7 is fixed to the outer edge of the positioning sealing disc 4.
[0030] Further as Figure 3 As shown, it is worth noting that the inner ring wall of the annular fixed frame 7 is provided with an exhaust hole 11, the interior of the overflow treatment shell 8 is provided with an annular receiving groove 27, the pressure relief cotton layer 9 is embedded in the annular receiving groove 27 of the overflow treatment shell 8, the exhaust hole 11 is connected to the annular receiving groove 27 of the overflow treatment shell 8, and the end faces of the annular fixed frame 7 and the overflow treatment shell 8 are on the same vertical plane.
[0031] This solution has the following working process: Before use, the control adjustment handwheel 19 rotates the locking screw 14 along the locking screw sleeve 13 of the cover mounting bracket 12, causing the rotating block 16 at one end of the locking screw 14 to rotate in the anti-detachment rotating housing 17. As the locking screw 14 rotates outward, it causes the sealing cover 15 to move outward from the annular fixed frame 7, widening the distance between the cover inlet 5 and the sealing cover 15. The way the sealing cover 15 moves outward from the front end of the cover inlet 5 facilitates the positioning and closing operation after material addition. Furthermore, the sealing cover 15 is in a suspended, fixed-point position, eliminating the tedious manual handling during opening and closing, and providing conditions for rapid cleaning of the cover. When opening the cover, the control adjustment handwheel 19 rotates outward... Rotate the locking screw 14 and adjust the position of the sealing cover 15 until it is at the front edge of the annular fixed frame 7. This places the sealing cover 15 in front of the exhaust hole 11 on the inner wall of the annular fixed frame 7, making the cover inlet 5, exhaust hole 11, overflow treatment shell 8, overflow discharge pipe 21, and overflow inlet pipe 22 connected. When the fan assembly 23 is turned on, the working fan assembly 23 can guide the hot air into the activated carbon adsorption device 24 through the overflow inlet pipe 22. The hot air is then discharged after being harmlessly treated by the activated carbon adsorption device 24. This improves the environmental friendliness of the device and prevents polluted gas from directly overflowing into the workplace and causing safety hazards to personnel health.
[0032] According to the above working process, the sealing cover 15 moves outward from the annular fixed frame 7, widening the gap between the sealing cover inlet 5 and the sealing cover 15. The way the sealing cover 15 moves out of the front end of the sealing cover inlet 5 facilitates the positioning and closing operation after material addition. The sealing cover 15 is in a suspended and fixed position, eliminating the tedious operation of manual handling during opening and closing, and providing conditions for rapid cleaning of the cover. When the fan assembly 23 is turned on, the working fan assembly 23 can introduce hot air into the activated carbon adsorption device 24 through the overflow inlet pipe 22. The hot air is discharged after being harmlessly treated by the activated carbon adsorption device 24. This can improve the environmental protection of the device and prevent polluted gas from directly overflowing into the workplace and causing safety hazards to personnel health.
[0033] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a communication port 28 is provided at the contact point between the overflow discharge pipe 21 and the overflow treatment shell 8. The upper end of the overflow discharge pipe 21 is welded and fixed to the lower part of the overflow treatment shell 8. An air guide channel 32 is provided inside the overflow discharge pipe 21. The air guide channel 32 of the overflow discharge pipe 21 is connected to the annular receiving groove 27 of the overflow treatment shell 8.
[0034] Further as Figure 6 and Figure 7 As shown, it is worth noting that the upper part of the fan assembly 23 is fixed to the lower end of the overflow discharge pipe 21, and the lower part of the fan assembly 23 is fixed to the upper end of the overflow inlet pipe 22.
[0035] Further as Figure 4 As shown, it is worth noting that the lower end of the overflow inlet pipe 22 is connected to the inlet of the activated carbon adsorption device 24, and an exhaust pipe 25 is fixed at the outlet of the activated carbon adsorption device 24. A control panel 26 is provided on the front surface of the activated carbon adsorption device 24. The overflow treatment shell 8, the overflow discharge pipe 21, the overflow inlet pipe 22, the activated carbon adsorption device 24 and the exhaust pipe 25 are connected in sequence.
[0036] Further as Figure 4 and Figure 5 As shown, it is worth noting that a cover mounting bracket 12 is fixed to the front end face of the overflow treatment shell 8. A locking screw sleeve 13 is fixed at the center of the front end face of the cover mounting bracket 12. A locking screw hole 20 is provided inside the locking screw sleeve 13. A locking screw 14 is passed through the surface of the cover mounting bracket 12. The locking screw 14 is threadedly connected to the locking screw sleeve 13 in the locking screw hole 20. An anti-detachment rotation shell 17 is fixed at the center of the front surface of the sealing cover 15. A rotation groove is provided inside the anti-detachment rotation shell 17. A rotating block 16 is rotatably connected in the rotation groove of the anti-detachment rotation shell 17. One end of the locking screw 14 that extends into the anti-detachment rotation shell 17 is fixed at the center of the front end face of the rotating block 16. An adjusting handwheel 19 is fixed at the other end of the locking screw 14 that extends out of the anti-detachment rotation shell 17.
[0037] Further as Figure 5 As shown, it is worth noting that a positioning pin 18 is fixed on the rear surface of the sealing cover 15, and a positioning hole 6 is horizontally penetrated through the front surface of the positioning sealing plate 4. The positioning pin 18 engages with the positioning hole 6, and the number of positioning pins 18 is equal to the number of positioning holes 6. The feed inlet 5 is opened inside the feed pipe 3 and the positioning sealing plate 4. The sealing cover 15 is placed in front of the feed inlet 5. When the sealing cover 15 is initially opened, the sealing cover 15 cooperates with the annular fixed frame 7 to shield the hot air and discharge it to the outside through the exhaust pipe 25. This can reduce the trouble of hot air escaping and scalding the operator when the sealing cover 15 is first opened. When closing the feed inlet 5 of the feed pipe 3, the control adjustment handwheel 19 is turned inward to lock the screw 14 and adjust the sealing cover 15 to be in the position of the annular fixed frame 7 until the rotating block 16 presses against the sealing cover 15 and seals it with the feed inlet 5 of the feed pipe 3.
[0038] Further as Figure 3As shown, it is worth noting that a lifting bracket 2 is fixed to the lower part of the pressure vessel body 1, a lifting lug 29 is fixed to the upper part of the pressure vessel body 1, an air outlet pipe 30 communicating with its inner cavity is fixed to the upper part of the pressure vessel body 1, and a discharge port 31 communicating with its inner cavity is fixed to the lower part of the pressure vessel body 1.
[0039] In summary: The sealing cover 15 moves outward from the annular fixed frame 7, widening the gap between the sealing cover inlet 5 and the sealing cover 15. Moving the sealing cover 15 outward from the front of the sealing cover inlet 5 facilitates the positioning and closing operation after material addition. Furthermore, the suspended, fixed-point placement of the sealing cover 15 eliminates the tedious manual handling required for opening and closing, and facilitates rapid cleaning of the cover. When the fan assembly 23 is turned on, the working fan assembly 23 can guide hot air through the overflow inlet pipe 22 into the activated carbon adsorption device 24. The hot air is then harmlessly treated by the activated carbon adsorption device 24 before being discharged, thus improving the environmental friendliness of the device and preventing the direct overflow of polluting gases into the workplace, which could cause health hazards to personnel. The sealing cover 15, in conjunction with the annular fixed frame 7, shields the hot air and discharges it outdoors through the exhaust pipe 25, reducing the risk of burns to operators from hot air escaping when the sealing cover 15 is first opened.
[0040] The fan assembly 23 can be purchased from the market and is equipped with a power supply. This is a mature technology in the field and has been fully disclosed, so it will not be repeated in the specification.
