Description

Technical Field

[0001] The utility model relates to the technical field of converter gas holders, in particular to a one-stage converter gas holder. Background Art

[0002] A dry rubber membrane gas holder is a fully dry gas holder that does not use liquids and semi-liquids such as water and grease. It uses a rubber membrane as the sealing medium and has excellent sealing performance. It is suitable for gas storage environments with a large amount of dust, high humidity, and many toxic gas components. A dry rubber membrane gas holder, also known as a Wiggins gas holder or a rolling curtain seal gas holder, belongs to the auxiliary equipment system of the steelmaking system and is an important equipment for converter gas recovery. It has the functions of storage, pressure stabilization, and mixing. This gas holder has good sealing performance, can adapt to harsh working environments, and ensures the efficiency and safety of gas recovery. The design and manufacture of a dry rubber membrane gas holder are relatively simple, with fewer auxiliary equipment, fewer processed parts and prefabricated parts, which makes its construction and maintenance costs lower. In addition, since its sealing material is flexible rubber, the piston lift is not restricted by the sealing fit, so it has a large throughput and can quickly respond to changes in gas supply and demand. This gas holder has a wide range of applications, can save energy and maintenance costs, and is a key facility for gas recovery and comprehensive utilization in the metallurgical industry.

[0003] According to the patent number CN104344206B published on the Chinese Patent Network, the patent name is a high-pressure and constant-pressure two-stage rubber membrane sealed gas holder, which is mainly designed to provide a safer and more reliable gas holder.

[0035] Working principle and usage process of the utility model: During use, first, the rubber sealing film 4 is video-monitored by the video monitor 16, and the gas at the ventilation pipe 9 is detected by the gas detection probe 15. Then, the video monitoring data and gas detection data are transmitted into the control terminal 2, and the control terminal 2 processes and judges the data. When a ruptured rubber sealing film 4 appears in the video monitoring data and the gas detection probe 15 detects the gas stored in the gas storage tank 1, the control terminal 2 sends a signal to the motor 11 to start the motor 11. The output end of the motor 11 drives the screw rod 12 to rotate, and the screw rod 12 moves downward by using the screw sleeve 13. The screw rod 12 drives the motor 11 and the shielding cover 10 to move downward, and the shielding cover 10 drives the sealing ring 23 to move downward, so that the sealing ring 23 fits tightly with the ventilation pipe 9. At the same time, the control terminal 2 sends signals to the solenoid valve I 6 and the solenoid valve II 8 to close the solenoid valve I 6 and open the solenoid valve II 8. At this time, the leaked gas can be transported to another intact gas storage tank 1 through the spare exhaust pipe 7, so as to achieve the effect of having a leakage protection function.

[0036] In summary, for this one-piece converter gas holder, by setting the gas storage tank 1, the control terminal 2, the piston 3, the rubber sealing film 4, the gas transmission pipe 5, the solenoid valve I 6, the spare exhaust pipe 7, the solenoid valve II 8, the ventilation pipe 9, the shielding cover 10, the motor 11, the screw rod 12, the screw sleeve 13, the connecting rod 14, the gas detection probe 15, and the video monitor 16, the problem that the one-piece converter gas holder does not have a leakage protection function is solved. At present, most one-piece converter gas holders use rubber membranes for sealing. The rubber membranes are very easy to rupture and damage after long-term use, resulting in the leakage of the gas stored inside and causing huge economic losses.
