Description

Technical Field

[0001] This invention relates to the field of gas drainer replacement equipment, and more particularly to a system for the safe replacement of gas drainers. Background Technology

[0002] A gas drainer is a device that facilitates the real-time drainage of condensate from gas pipelines. It is widely used in blast furnaces, ironmaking, steelmaking, and rolling mills in steel plants and is a reliable condensate draining device. Because gas contains a large number of impurities, these impurities will enter the gas drainer along with the condensate. Some of these impurities will flow out with the condensate, while others will remain in the gas drainer, requiring regular cleaning. During cleaning, because the gas drainer is connected to the gas pipeline, the valves on the pipeline may not reliably shut off the gas flow. Due to the long cleaning time, if there are fluctuations in gas pressure, some gas may enter the drainer through the valves, potentially causing poisoning to the cleaning personnel. Furthermore, since the gas drainer is located on the ground, factors such as ground subsidence may cause it to become suspended, potentially leading to gas pipeline breakage and posing a significant safety risk.

[0003] Therefore, a system for the safe replacement of gas drainers is provided to solve the above-mentioned problems. Utility Model Content

[0004] The main purpose of this utility model is to solve the problems in the existing technology, such as the gas drainer being connected to the gas pipeline, the valves in the gas pipeline not being able to reliably shut off the gas during the cleaning process, the long cleaning time, and the possibility that some gas may enter the drainer through the valve if the gas pressure fluctuates, causing poisoning to the personnel cleaning the gas drainer; and the gas drainer being located on the ground, which may cause the gas drainer to become suspended due to ground subsidence and other factors, resulting in the gas pipeline breaking and posing a great safety risk.

[0005] This utility model provides a system for the safe replacement of gas drainers, the system comprising: A gas drainer mounting base is provided, on which a height-adjustable base is fixedly installed. A drainer replacement bracket is fixedly installed on both sides of the height-adjustable base. A drainer replacement position is provided at the end of the drainer replacement bracket away from the height-adjustable base. A spare drainer is placed directly above the drainer replacement position. A gas drainer is fixedly installed on the height-adjustable base.

[0006] Optionally, the gas drainer and the standby drainer have the same structure. The gas drainer includes a drainer body, an upper pipe at the upper end of the drainer body, a condensate drain pipe on the front of the drainer body, first positioning pin holes on both the left and right sides of the bottom of the drainer body, and sliding grooves on the front and rear sides of the bottom of the drainer body. The sliding grooves are used to cooperate with the drainer replacement bracket.

[0007] Optionally, the top of the upper pipe is provided with a flange structure for connecting to an external gas pipeline.

[0008] Optionally, the drain replacement bracket includes a horizontal rail and a support rod. The support rod is vertically disposed below the horizontal rail and fixedly connected to the horizontal rail. The support rod is used to support the horizontal rail, and the horizontal rail is used to support the sliding of the gas drain and the standby drain.

[0009] Optionally, the support rod is a hydraulic telescopic rod.

[0010] Optionally, the drain station to be replaced includes a first crossbar and a second crossbar, the first crossbar and the second crossbar being fixedly installed on the horizontal rail, and both the first crossbar and the second crossbar being fixedly provided with a second positioning pin hole in conjunction with the first fixing pin hole.

[0011] Optionally, the height adjustment base is fixedly provided with second positioning pin holes on both sides.

[0012] Optionally, the horizontal track is concave, and a row of rollers is rotatably mounted inside the horizontal track.

[0019] This utility model provides a system for the safe replacement of gas drainers, comprising: a gas drainer mounting base, a height-adjustable base fixedly mounted on the gas drainer mounting base, drainer replacement brackets fixedly mounted on both sides of the height-adjustable base, a drainer to be replaced station set at the end of the drainer replacement bracket away from the height-adjustable base, a spare drainer placed directly above the drainer to be replaced station, and a gas drainer fixedly mounted on the height-adjustable base. The main purpose of this utility model is to solve the problem that in the prior art, the replacement of belt under-rollers is usually completed manually with the aid of tools. Although the known related tools can save some time and reduce the labor intensity of workers to a certain extent, the degree of automation is low, and most steps still require manual intervention, which does not achieve the effect of completely liberating labor. In addition, some highly automated ones have the problem of high cost, and the existing roller replacement devices do not take into account the problem of whether the roller will come out of the restraint during the roller replacement process.

When replacement is needed, first shut off the external gas pipeline, then shut off the gas drainer, remove the flange connected to the gas pipeline, unlock the pin, and then use a pry bar to move the gas drainer along the track to the empty space for the drainer to be replaced. After securing it with the pin, remove the pin of the standby drainer, then move the standby drainer along the track and with the pry bar to the height adjustment base, secure it with the pin, and then adjust the height so that the flange of the upper pipe of the standby drainer matches the flange of the external gas pipeline. Secure it, open the standby drainer, open the external gas pipeline, and the replacement is complete. Clean the gas drainer located in the empty space for the drainer to be replaced. The two gas drainers are then used alternately according to the above procedure, generally replaced every 2-3 months.

[0028] Example This embodiment provides a system for the safe replacement of a gas drainer, the system comprising: A gas drainer mounting base 1 is provided, on which a height adjustment base 2 is fixedly installed. The height adjustment base includes a platform and a height adjustment rod. The upper end of the height adjustment rod is fixedly connected to the platform, and the lower end of the height adjustment rod extends into the gas drainer mounting base. The height adjustment rod is threaded and fitted with a nut. By adjusting the nut, the extent to which the height adjustment rod extends into the gas drainer mounting base is adjusted, thereby adjusting the height. The height that can be adjusted by this height adjustment rod is relatively small. Drainer replacement brackets are fixedly installed on both sides of the height adjustment base. A drainer replacement bracket 4 is provided at the end away from the height adjustment base, where a drainer to be replaced is located. A spare drainer 5 is placed directly above the drainer to be replaced. A gas drainer 3 is fixedly installed on the high-end adjustment base.

[0029] The gas drainer and the standby drainer have the same structure. The gas drainer includes a drainer body, an upper pipe 302 at the upper end of the drainer body, a condensate drain pipe 301 on the front of the drainer body, first positioning pin holes on the left and right sides of the bottom of the drainer body, and sliding grooves on the front and rear sides of the bottom of the drainer body. The sliding grooves are used to cooperate with the drainer replacement bracket.

[0030] The top of the upper pipe is equipped with a flange structure for connecting to an external gas pipeline.

[0031] The drain replacement bracket includes a horizontal rail and a support rod. The support rod is vertically positioned below the horizontal rail and is fixedly connected to the horizontal rail. The support rod is used to support the horizontal rail, and the horizontal rail is used to support the sliding of the gas drain and the standby drain.

When replacement is needed, first close the external gas pipeline, then close the gas drainer, remove the flange connected to the gas pipeline, unlock the pin, and then push the gas drainer to the empty space for the drainer to be replaced via the track and roller structure. (During this process, the height of the support rod can be adjusted so that the height of the empty space for the drainer to be replaced is slightly lower than the height adjustment base for easy pushing. At this time, the connection between the track and the height adjustment base can be changed to a rotating connection to meet this design. After pushing is completed, the height of the support rod can be adjusted back to its original position.) After securing the gas drain, remove the pin from the spare drainer. Then, push the spare drainer onto the height-adjustable base using the track and roller structure. (During this process, the support rod height can be adjusted so that the initial position of the spare drainer is slightly higher than the height-adjustable base for easier pushing. The connection between the track and the height-adjustable base can be changed to a swivel connection to meet this design requirement. After pushing, the support rod height can be adjusted back to its original position.) Secure the spare drainer with the pin, then adjust the height so that the flange of the upper pipe of the spare drainer matches the flange of the external gas pipe.
