Description

Technical Field

[0001] The utility model belongs to the technical field of acetylene production, and particularly relates to a high-pressure dryer for dissolved acetylene production. Background Art

[0002] The high-pressure dryer for dissolved acetylene production is a device used to dry acetylene gas. Its working principle is to use a desiccant (such as calcium chloride) to adsorb the moisture in the acetylene gas, so as to achieve the purpose of drying. In the production process of acetylene gas, when the acetylene gas after three-stage compression reaches the process pressure requirement, it will enter a high-pressure dryer filled with anhydrous calcium chloride for further purification and drying, and then enter the gas cylinder post for filling acetylene gas cylinders;

[0003] The drying tube is the core component of the acetylene dryer. It is usually made of stainless steel or other corrosion-resistant materials. The drying tube is filled with desiccants such as calcium chloride and molecular sieve to absorb the moisture in the acetylene gas. According to the specified time interval or according to the drying effect, the desiccant is replaced in time to ensure its drying performance. When replacing, it is necessary to separate the relevant gas transmission equipment of the dryer bottle, and by replacing the gas in its bottle, the acetylene gas is discharged and then the desiccant is replaced. After the drying gas cylinder is separated from the connecting pipeline, if there is residual acetylene gas in the pipeline that has not been discharged, it will leak, which is not conducive to the safe operation of the staff. Summary of the Utility Model

[0004] The utility model provides a high-pressure dryer for dissolved acetylene production, which has the characteristic of solving the problem that if there is residual acetylene gas in the pipeline during the replacement of the desiccant, it will leak, which is not conducive to the safe operation of the staff.

[0017] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: It includes a base 1, a rotating groove 11 is opened on the base 1, a support plate 12 is rotatably connected to the inner wall of the rotating groove 11, two lower mounting holes 13 that are communicated with each other are opened on the base 1 and the support plate 12, a drying bottle body 2 and a closed bottle 23 are butted on the two lower mounting holes 13, two fixing plates 41 are snap-connected to the tops of the drying bottle body 2 and the closed bottle 23, an installation rod 42 is fixedly connected between the fixing plates 41, a spring 43 is fixedly connected to the top end of the installation rod 42, a top plate 31 is arranged above the base 1, a sliding rod 4 is fixedly connected to the center of the top plate 31, the driving end of the sliding rod 4 is fixedly connected to the spring 43, an upper mounting hole 33 corresponding to the lower mounting hole 13 is opened on the top plate 31, a communicating member 32 is installed on one of the upper mounting holes 33 and the lower mounting hole 13, and a sealing plate 35 is detachably connected to one of the upper mounting holes 33 and the lower mounting hole 13.

[0018] In this embodiment: The base 1 is the carrier of the loading device. The support plate 12 can be installed through the rotation groove 11 opened on the base 1, so that the lower mounting holes 13 opened on the support plate 12 communicate with the lower mounting holes 13 opened on the base 1, enabling the drying bottle body 2 and the closed bottle 23 installed on the lower mounting holes 13 to communicate with the lower mounting holes 13. The top of the drying bottle body 2 and the closed bottle 23 is connected to the top plate 31 and communicates through the upper mounting hole 33 opened on the top plate 31. The drying bottle body 2 is used to dry and filter the acetylene gas through the drying tube provided inside after the acetylene gas is introduced. The connecting member 32 fixedly connected to the upper mounting hole 33 can be connected to the pipeline for transmitting acetylene gas, enabling the acetylene gas to be transmitted through the drying bottle body 2, so that the device can perform the transmission work on the transmitted acetylene gas. Since the desiccant in the drying tube needs to be replaced in a timely manner at regular time intervals or according to the drying effect to ensure its drying performance, when overhauling and replacing it, the drying bottle body 2 needs to be separated. Before separating the drying bottle body 2, the remaining acetylene gas inside it needs to be discharged. By connecting a nitrogen cylinder, opening the nitrogen valve, and filling nitrogen into the dryer for replacement, the purpose of replacement is to discharge the acetylene gas in the dryer to ensure safety when replacing the desiccant. When disassembling the drying bottle body 2 to replace the desiccant, since the drying bottle body 2 is directly separated from the equipment for dredging acetylene, even if the gas in the drying bottle body 2 can ensure safety when replacing the desiccant after replacement, the equipment such as pipelines connecting the drying bottle body 2 will have residual acetylene gas when stopped working. When separating the drying bottle body 2, it is easy for the residual acetylene gas to leak. At this time, the driving end of the sliding rod 4 can be connected to the spring 43, and the spring 43 is connected to the mounting rod 42. The mounting rod 42 connects and fixes the two fixing plates 41, enabling the sliding rod 4 to drive the mounting rod 42 to drive the drying bottle body 2 and the closed bottle 23 to perform synchronous displacement and replace their positions. After the closed bottle 23 is connected between the connecting members 32, after the acetylene gas is disconnected from the drying bottle body 2, acetylene gas leakage can be avoided. The drying bottle body 2 directly rotates to the position of another opened upper mounting hole 33. At this time, the upper mounting hole 33 and the lower mounting hole 13 corresponding to the drying bottle body 2 are closed by the sealing plate 35 to prevent acetylene leakage from the drying bottle body 2. Through the preset gas replacement pipeline, the acetylene gas in the drying bottle body 2 is safely replaced. After the sealing plate 35 is opened, operations such as replacing the desiccant are performed, so that the device can ensure that the acetylene gas in the drying bottle body 2 can be replaced while preventing the acetylene gas in the pipeline connected to the drying bottle body 2 from leaking when separating the drying bottle body 2, thereby ensuring safety when replacing the desiccant.

[0019] A fixing rod 3 is fixedly connected to the top of the base 1, and the fixing rod 3 is connected to the top plate 31 via a threaded rod 37; the fixing rod 3 fixedly connected to the top of the base 1 is used to install the top plate 31, and is connected to the top of the fixing rod 3 via the threaded rod 37, so that the top plate 31 is connected and installed on the fixing rod 3, so that the base 1 and the top plate 31 are connected and fixed up and down.

[0020] A sealing block 36 is installed at the center of the sealing plate 35, and a plug rod 351 is fixedly connected to the bottom end of the sealing plate 35. A connecting hole 34 is opened on the top plate 31, and a fixing ring 21 corresponding to the connecting hole 34 is fixedly connected to the top of the drying bottle body 2 and the closing bottle 23, and a fixing hole 22 is opened on the fixing ring 21; the sealing block 36 installed at the center of the sealing plate 35 is used to facilitate the removal of the sealing block 36, after the desiccant in the drying bottle body 2 is replaced, acetylene gas is injected into it, and then the position of the drying bottle body 2 and the closing bottle 23 are controlled to be exchanged, so that the drying bottle body 2 is connected with the connecting piece 32 again to perform gas drying work.

[0021] A connecting pipe 321 is fixedly connected to the connecting piece 32, and corresponding sliding holes 44 are opened at the inner wall of the rotating groove 11 and the center of the support plate 12, and the inner wall of the sliding hole 44 is slidably connected to the sliding rod 4; the connecting pipe 321 fixedly connected to the connecting piece 32 is used to connect the connecting piece 32 with the pipeline for conveying acetylene gas, and the sliding hole 44 is used to install the sliding rod 4, and the supporting plate 12 can be limited in the rotating groove 11 by the sliding rod 4 so that it cannot rotate, and the position of the drying bottle body 2 and the sealing bottle 23 can be adjusted. When the position needs to be adjusted, the sliding rod 4 is slid upward to make the sliding rod 4 misaligned with the sliding hole 44 opened on the inner wall of the rotating groove 11, so that the support plate 12 can rotate.

[0022] A fixing plate 41 is fixedly connected to the top of the slide rod 4, and a mounting rod 42 is slidably connected to the support plate 12. The top of the mounting rod 42 is fixedly connected to the fixing plate 41, and a spring 43 is sleeved on the outer wall of the spring 43; the fixing plate 41 is used to install and fix the mounting rod 42. When the mounting rod 42 slides on the support plate 12, the fixing plate 41 is pulled downward by the spring 43, so that the slide rod 4 can be ensured to be engaged between the upper and lower sliding holes 44, thereby limiting the position of the support plate 12.

[0023] Working principle and usage process of the utility model: The connecting member 32 installed on the top plate 31 is docked with the connecting member 32 installed on the base 1 to connect the drying bottle body 2, enabling acetylene gas to pass through the inner cavity of the drying bottle body 2. The gas is dried by the drying tube provided in the drying bottle body 2. When it is necessary to replace the desiccant in the drying bottle body 2, the sliding rod 4 can drive the spring 43 to drive the mounting rod 42 and the fixing plate 41 to rotate at this time, driving the drying bottle body 2 and the closed bottle 23 to displace synchronously, replacing the positions of the two. After the closed bottle 23 is connected between the connecting members 32, after the acetylene gas is disconnected from the drying bottle body 2, acetylene gas leakage can be avoided. The drying bottle body 2 directly rotates to the position of another upper mounting hole 33 opened. At this time, the upper mounting hole 33 and the lower mounting hole 13 corresponding to the drying bottle body 2 are closed by the sealing plate 35 to prevent acetylene leakage from the drying bottle body 2. Through the preset gas replacement pipeline, the acetylene gas in the drying bottle body 2 is safely replaced. After the sealing plate 35 is opened, operations such as replacing the desiccant are carried out. Thus, when the device separates the drying bottle body 2, it can ensure that the acetylene gas in the drying bottle body 2 can be replaced while preventing the acetylene gas in the pipeline connected to the drying bottle body 2 from leaking, thereby ensuring the safety when replacing the desiccant.
