Technical Field
[0001] This utility model belongs to the technical field of emergency shut-off devices, specifically relating to an emergency shut-off device for valves on the flue gas end of an electrolytic cell that is easy to maintain. Background Technology
[0002] The emergency shut-off device for the flue gas end pipeline valve of an electrolytic cell is a safety device primarily designed to quickly close the pipeline valve at the flue gas end of the electrolytic cell in emergency situations. This device can rapidly and effectively cut off the fluid passage at the flue gas end of the electrolytic cell upon detecting an abnormality or receiving a shut-off signal, preventing further leakage of harmful gases or liquids, thereby protecting personnel safety, preventing environmental pollution, and maintaining the stability of the production process.
[0003] However, traditional valve emergency shut-off devices are not easy to disassemble. During regular maintenance or emergency repairs, staff need to spend more time disassembling and assembling various components. This not only prolongs the maintenance time but may also prevent timely emergency operations in case of an emergency. In addition, the disassembly process may require the use of special tools or equipment, which increases the complexity and cost of maintenance.
[0004] To address this issue, an emergency shut-off device for the valves on the flue gas duct of the electrolytic cell was designed for easy maintenance. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides an emergency shut-off device for valves on the flue gas end of an electrolytic cell that is easy to maintain.

The easily maintainable valve emergency shut-off device body design facilitates daily maintenance and inspection by staff. The device's detachability, ease of observation, and operation greatly shorten maintenance time and improve maintenance efficiency. Due to the increase in temperature, the magnetism of the temperature-sensing soft magnet decreases. At this time, the push rod disengages from the bottom of the alarm, and the spring releases its elastic potential energy. Under the action of the spring, the push rod will press against the alarm switch, at which point the alarm will sound, reminding staff to take appropriate action immediately, further increasing the safety of the device.

[0027] An emergency shut-off device for the valve of the flue gas end of an electrolytic cell, which is easy to maintain, includes the body 1 of the flue gas end of the electrolytic cell.
[0028] In this implementation plan: However, traditional valve emergency shut-off devices are not easy to disassemble. During regular maintenance or emergency repairs, staff need to spend more time disassembling and assembling various components. This not only prolongs the maintenance time but may also lead to the inability to carry out emergency operations in a timely manner in an emergency. At the same time, the disassembly process may require the use of special tools or equipment, which increases the complexity and cost of maintenance. To solve this technical problem, an alarm component 2 is added on this basis.
[0029] Furthermore:
[0030] like Figures 1 to 6 As shown:
[0031] Based on the above: the alarm component 2 includes a valve emergency shut-off device body 21, a first connecting plate 22, and a second connecting plate 23.

When the user needs to assemble the device, simply align the first connecting plate 22 of the electrolytic cell flue end body 1 with the second connecting plate 23 of the valve emergency shut-off device body 21, and then insert the rod-shaped insertion rod 24 through the first connecting plate 22 and the second connecting plate 23. At this time, threaded sleeve 26 is connected to one end of the insertion rod 24, and the first limiting ring 27 is fitted onto the outer side of the other end of the insertion rod 24. Then, the first limiting ring 27 is rotated to a certain extent to position the first limiting rod 24 at the end of the insertion rod 24. 5. Align with the first slot 28. At this time, rotate the threaded sleeve 26 to drive the insertion rod 24 to move to a certain extent, so that the first limiting rod 25 at the end of the insertion rod 24 can be engaged in the interior of the first slot 28. Then, the electrolytic cell flue end body 1 can be connected to the valve emergency shut-off device body 21. When the user needs to quickly disassemble the electrolytic cell flue end body 1, simply rotate the threaded sleeve 26 in the opposite direction to make the first limiting rod 25 at the end of the insertion rod 24 slide out from the interior of the first slot 28. Then rotate the first limiting ring 27 and disassemble the first limiting ring 27 through the first through groove 29. The valve emergency shut-off device body 21 can be quickly disassembled from the outside of the end of the electrolytic cell flue end body 1. The valve emergency shut-off device body 21 is designed to be easy to maintain, which can facilitate the daily maintenance and inspection of the staff.

[0035] In this embodiment: a second limiting rod 211 is fixedly connected to the outer end of the insertion rod 24, and a second limiting ring 212 is detachably connected to the outer end of the insertion rod 24. A rubber pad 214 is fixedly connected to the outer end of the second limiting ring 212. When assembling the valve emergency closing device body 21, the insertion rod 24 can first pass through the first connecting plate 22, and then the second limiting ring 212 can pass through the other end of the insertion rod 24, so that the second limiting rod 211 is inserted into the second slot 213 of the second limiting ring 212. Then, the second connecting plate 23 is sleeved on the outer end of the insertion rod 24, and the insertion rod 24 passes through the end of the second limiting ring 212. At this time, the first limiting ring 27 is set on the second connecting plate 212. On one side of the connecting plate 23, the first limiting ring 27 is fitted onto the outer side of the end of the insertion rod 24. Then, the first limiting ring 27 is rotated to insert the first limiting rod 25 into the inside of the first slot 28. Through the second limiting ring 212 and the rubber pad 214, the first connecting plate 22 and the second connecting plate 23 can be prevented from directly contacting each other. Since the first connecting plate 22 and the second connecting plate 23 do not directly contact each other, wear caused by friction is avoided. The rubber pad 214 has a good buffering and vibration reduction effect, which can reduce the vibration and noise caused by impact on the electrolytic cell flue end body 1 and the valve emergency closing device body 21. This not only improves the working environment, but also helps to reduce potential damage to the equipment caused by vibration and increases the service life of the device.
[0036] Furthermore:
[0037] In an optional embodiment, a rotating groove 210 is provided on the inner side of the end of the threaded sleeve 26.
[0038] In this embodiment, a rotating groove 210 is provided on the inner side of the end of the threaded sleeve 26. The rotating groove 210 is ergonomic and makes it easier for the user to rotate the threaded sleeve 26 to fix the device, thus improving the user experience.
[0039] Furthermore:
[0040] In an optional embodiment, an alarm 215 is installed on the inner side of the end of the valve emergency shut-off device body 21, and a push rod 216 is slidably connected to the inner side of the bottom end of the valve emergency shut-off device body 21. The outer sides of both ends of the spring 217 are fixedly connected to the lower surface of the end of the push rod 216 and the inner side of the bottom end of the alarm 215, respectively. A temperature-sensing soft magnet 218 is fixedly connected to the lower surface of the end of the push rod 216, and a heat-conducting plate 219 is fixedly connected to the outer side of the end of the alarm 215.
[0041] In this implementation scheme: An alarm 215 is installed on the inner side of the end of the valve emergency shut-off device body 21. A switch is provided at the bottom of the alarm 215. When the device is working, the user can pull the push rod 216 and compress the spring 217 at the same time, so that the spring 217 stores elastic potential energy. At the same time, the push rod 216 is magnetically connected to the bottom of the alarm 215 through the temperature-sensing soft magnet 218. When the internal temperature of the body 1 at the end of the electrolytic cell flue rises, the temperature will be transferred to the bottom of the alarm 215 through the heat-conducting plate 219. At this time, due to the increase in temperature, the magnetism of the temperature-sensing soft magnet 218 will decrease. At this time, the push rod 216 will disengage from the bottom of the alarm 215, and the spring 217 will release elastic potential energy. Under the action of the spring 217, the push rod 216 will press against the switch of the alarm 215. At this time, the alarm 215 will start to sound, reminding the staff to take appropriate action in time, which further increases the safety of the device.
[0042] Working principle: In this device, a valve emergency shut-off device body 21 is detachably connected to the outer side of the end of the electrolytic cell flue end body 1. Four first connecting plates 22 are fixedly connected in an circumferential manner to the outer side of the end of the electrolytic cell flue end body 1. The first connecting plates 22 have an L-shaped structure. At the same time, four second connecting plates 23 are fixedly connected in an circumferential manner to the outer side of the end of the valve emergency shut-off device body 21. The insertion rod 24 has a rod-shaped structure. When the user needs to assemble the device, simply align the first connecting plate 22 of the electrolytic cell flue end body 1 with the second connecting plate 23 of the valve emergency shut-off device body 21, and then insert the rod-shaped insertion rod 24 through the first connecting plate 22 and the second connecting plate 23. At this time, thread a threaded sleeve 26 is threaded to one end of the insertion rod 24, and the first... The limiting ring 27 is sleeved on the outer side of the other end of the insertion rod 24. Then, by rotating the first limiting ring 27 to a certain extent, the first limiting rod 25 at the end of the insertion rod 24 is aligned with the first slot 28. At this point, rotating the threaded sleeve 26 will cause the insertion rod 24 to move to a certain extent, allowing the first limiting rod 25 at the end of the insertion rod 24 to engage with the inside of the first slot 28. This allows the electrolytic cell flue end body 1 to be connected to the valve emergency shut-off device body 21. When the user needs to quickly disassemble the electrolytic cell flue end body 1, simply rotate the threaded sleeve 26 in the opposite direction, causing the first limiting rod 25 at the end of the insertion rod 24 to slide out of the first slot 28. Then, rotate the first limiting ring 27 to disassemble it through the first through groove 29, thus allowing the valve to be closed. The emergency shut-off device body 21 can be quickly disassembled from the outer end of the body 1 at the end of the electrolytic cell flue. The valve emergency shut-off device body 21, designed for easy maintenance, facilitates routine maintenance and inspection by personnel. The device's detachability, ease of observation, and operation significantly shorten maintenance time and improve efficiency. A second limiting rod 211 is fixedly connected to the outer end of the insertion rod 24, and a second limiting ring 212 is detachably connected to the outer end of the insertion rod 24. A rubber pad 214 is fixedly connected to the outer end of the second limiting ring 212. When assembling the valve emergency shut-off device body 21, the insertion rod 24 can first pass through the first connecting plate 22, and then the second limiting ring 212 can pass through the other end of the insertion rod 24. The second limiting rod 211 is inserted into the second slot 213 of the second limiting ring 212. Then, the second connecting plate 23 is fitted onto the outer side of the end of the insertion rod 24, and the insertion rod 24 passes through the end of the second limiting ring 212. At this time, the first limiting ring 27 is placed on one side of the second connecting plate 23 and fitted onto the outer side of the end of the insertion rod 24. Then, the first limiting ring 27 is rotated to insert the first limiting rod 25 into the interior of the first slot 28. Through the second limiting ring 212 and the rubber pad 214, direct contact between the first connecting plate 22 and the second connecting plate 23 can be prevented. Since the first connecting plate 22 and the second connecting plate 23 do not directly contact each other, wear caused by friction is avoided. The rubber pad 214 has a good buffering and vibration damping effect.This reduces vibration and noise caused by impact on the electrolytic cell flue end body 1 and the valve emergency shut-off device body 21. This not only improves the working environment but also helps reduce potential damage to the equipment caused by vibration, increasing the service life of the device. A rotating groove 210 is annularly opened on the inner side of the end of the threaded sleeve 26. The rotating groove 210 is ergonomically designed, making it easier for users to rotate the threaded sleeve 26 to fix the device, thus improving the user experience. An alarm 215 is installed on the inner side of the end of the valve emergency shut-off device body 21. A switch is located at the bottom of the alarm 215. When the device is working, the user can pull the top rod 216 to compress the spring 21. 7. The spring 217 stores elastic potential energy, and the temperature-sensing soft magnet 218 magnetically connects the push rod 216 to the bottom of the alarm 215. When the internal temperature of the electrolytic cell flue end body 1 rises, the heat is transferred to the bottom of the alarm 215 through the heat-conducting plate 219. Due to the increased temperature, the magnetism of the temperature-sensing soft magnet 218 decreases, causing the push rod 216 to disengage from the bottom of the alarm 215. The spring 217 releases its elastic potential energy, and under the action of the spring 217, the push rod 216 will press against the switch of the alarm 215, triggering the alarm and alerting personnel to take immediate action, further increasing the safety of the device.
