Description

Technical Field

[0001] The utility model relates to the technical field of deflagration-proof flame arresters, in particular to a deflagration-proof flame arrester for RTO. Background Art

[0002] RTO is a regenerative thermal oxidizer. Its principle is to oxidize organic matter (VOCs) in the exhaust gas into corresponding carbon dioxide and water at high temperature, thereby purifying the exhaust gas and recovering the heat released when the exhaust gas is decomposed. The three-chamber RTO exhaust gas decomposition efficiency reaches more than 99%, and the heat recovery efficiency reaches more than 95%. The main structure of RTO consists of a combustion chamber, a regenerative chamber and a switching valve. When it is used, an anti-explosion flame arrester will be used to install it to prevent the transmission of the deflagration flame of the combustible gas.

[0003] When existing anti-explosion flame arresters are installed with RTO, they are mostly fixed with bolts through flanges. However, during actual installation, personnel are required to align the mounting holes between the flanges and then fix them with bolts. Personnel are required to hold them all the time. If personnel lose strength or touch them by mistake, the flanges will be offset, which will affect the installation efficiency. Utility Model Content

[0021] The fixed disk 50 is fixed on the surface of the flange 2, and a limiting groove 51 is provided on the surface of the fixed disk 50. A cavity 52 is provided inside the fixed disk 50. A sliding frame 53 is slidably connected to the inner wall of the cavity 52. ​​A block 54 is fixed on the inner side of the sliding frame 53. There are four groups of cavities 52 and sliding frames 53, and the four groups of cavities 52 and sliding frames 53 are arranged in a circular array with the center of the fixed disk 50 as the axis center. A connecting rod 56 is fixed between the four groups of sliding frames 53, and the connecting rod 56 passes through the cavity 52. ​​The connecting rod 56 is slidably connected to the fixed disk 50. A spring 55 is fixed on the surface of one side of the sliding frame 53 close to the block 54. The end of the spring 55 away from the sliding frame 53 is fixed on the inner wall of the cavity 52. ​​The flange 23 An L-shaped plate 57 is fixed on the surface, and a clamping hole 58 is opened on the surface of the L-shaped plate 57. The flange 1 2 and the flange 2 3 are close to each other, and the clamping rod 63 is pulled to make the clamping rod 63 separate from the fixed plate 62 and the handle 60, and the L-shaped plate 57 enters the limiting groove 51. The surface of the L-shaped plate 57 contacts the inclined surface of the clamping block 54, driving the sliding frame 53 to move in the cavity 52. ​​Through the connecting rod 56, the four groups of sliding frames 53 move synchronously, and the spring 1 55 is compressed. When the position of the clamping block 54 is parallel to the clamping hole 58, the spring 1 55 is released, and the sliding frame 53 drives the clamping block 54 to return to its position, and the clamping block 54 enters the clamping hole 58. The side of the clamping block 54 away from the inclined surface contacts the inner side of the clamping hole 58, thereby stabilizing the flange 1 2 and the flange 2 3.

[0022] The linkage assembly 6 includes a handle 60, which is fixed on the surface of one of the four groups of sliding frames 53. A connecting hole 61 is opened on the surface of the fixed plate 50, and the connecting hole 61 is communicated with the cavity 52. ​​The end of the handle 60 away from the sliding frame 53 passes through the connecting hole 61. A fixing plate 62 is fixed to the side of the fixing plate 50 away from the flange 23. A clamping rod 63 is arranged on the surface of the fixing plate 62, and the clamping rod 63 passes through the fixing plate 62 and the handle 60. When the clamping rod 63 is released, the spring 2 64 drives the clamping rod 63 to penetrate the handle 60 and the fixing plate 62, so that the sliding frame 53 is limited, which can prevent people from accidentally touching it, causing the clamping block 54 to separate from the clamping hole 58 and affect the installation. The clamping rod 63 is pulled out of the handle 60, and the handle 60 is rotated to drive the sliding frame 53 and the clamping block 54 to move, so that the clamping block 54 is separated from the clamping hole 58.

At this time, the surface of the L-shaped plate 57 contacts the inclined surface of the clamping block 54, and the sliding frame 53 is driven to move in the cavity 52. ​​Through the connecting rod 56, the four groups of sliding frames 53 move synchronously, and the spring 1 55 is compressed. When the position of the clamping block 54 is parallel to the clamping hole 58, the spring 1 55 is released, and the sliding frame 53 drives the clamping block 54 to return to its position. At this time, the clamping block 54 enters the clamping hole 58, and the clamping block 54 is away from the inclined surface. One side contacts the inner side of the clamping hole 58, thereby stabilizing flange 1 2 and flange 2 3, and there will be no accidental touch causing deviation. The clamping rod 63 is loosened, and at this time, the spring 2 64 drives the clamping rod 63 to penetrate the handle 60 and the fixing plate 62, so that the sliding frame 53 is limited, which can prevent people from accidentally touching it, causing the clamping block 54 to separate from the clamping hole 58 and affect the installation. At this time, the personnel can normally perform bolt fixing. When it is necessary to maintain the anti-explosion type flame arrester body 1, the bolts are removed at this time, and the clamping rod 63 is pulled out of the handle 60. The handle 60 is turned to drive the sliding frame 53 and the clamping block 54 to move, thereby causing the clamping block 54 to separate from the clamping hole 58. At this time, the personnel can normally separate the connecting pipe 4 from the anti-explosion type flame arrester body 1 for maintenance.
