Description

Technical Field

[0001] This utility model relates to the field of flame arrester technology, and in particular to flame arresters for chemical applications. Background Technology

[0002] A flame arrester consists of a flame arrestor core, a flame arrestor shell, and accessories. It is generally installed in pipelines that transport chemical products or on ventilated tanks. The function of a flame arrester is to prevent external flames from entering equipment or pipelines containing flammable and explosive gases or to prevent flames from spreading between equipment or pipelines.

[0003] After prolonged use, existing flame arresters tend to accumulate excessive foreign matter on the surface of the flame arrestor core, necessitating its replacement to avoid financial losses. However, the flame arrestor core is typically installed between two valve bodies, requiring the flame arrester to be disassembled in half to replace the core, and then the entire assembly must be reassembled for use, making the entire process quite cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flame arrester for chemical applications, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A shell plate, which is embedded in the shell opening of the outer shell, has an opening on the shell plate to facilitate the reception of the top block;

[0010] A side box is fixedly installed on the outer side wall of the outer shell. The side box has two openings and two cavities between it and the outer shell.

[0011] Two elastic limiting components are respectively installed in the corresponding box opening and box cavity on the side box. The two elastic limiting components are configured to clamp and fix the shell plate on the outer shell when they are close to each other; and to detach from the shell plate when the two elastic limiting components are far apart.

[0012] Preferably, the inner walls on both sides of the annular groove are provided with mounting grooves, and a sealing gasket is fixedly installed in the mounting groove. One side of the sealing gasket is sealed and fitted to one side of the flame arrestor core.

[0013] Preferably, the sealing gasket is a metal spiral wound gasket.

[0014] Preferably, the shell plate has a semi-circular annular cross-section, both the shell plate and the outer shell are made of stainless steel, and the side box has a semi-circular arc cross-section.

[0015] Preferably, the elastic limiting component includes:

[0016] A limiting plate is movably installed in the corresponding box opening and box cavity on the side box. The limiting plate has a C-shaped cross-section and is clamped to the surface of the outer shell plate. The limiting plate has a T-shaped handle, which is accommodated in the box opening of the side box. The inner wall of the limiting plate is provided with multiple limiting grooves.

[0017] Several springs, one end of each spring is fixedly installed on one side of the inner wall of the side box cavity, and the other end of each spring is fixedly installed on one side of the same limiting plate.

[0018] Preferably, a plurality of limiting strips are fixedly installed on the outer side wall of the outer shell, and the plurality of limiting strips are respectively embedded in the corresponding limiting grooves of the limiting plate, so that the limiting plate can slide in opposite directions on the plurality of limiting strips on the outer side wall of the outer shell.

[0019] Preferably, a support base is fixedly installed on the bottom side of the outer casing.

[0020] This application features an annular groove and an opening on the outer casing, allowing the flame arrestor core and casing plate to be sequentially embedded and installed. The flame arrestor core and casing plate are connected via a plug-in assembly. By simultaneously adjusting the T-shaped handles on the two limiting plates, the installer can adjust the opposing sliding positions of the two limiting plates inside the box. When the two limiting plates are adjusted to move away from each other, they detach from the casing plate. At this point, several springs on one side of the two limiting plates are deformed and compressed, making it easy to remove the casing plate from the opening. This facilitates quick inspection and replacement of the flame arrestor core inside the casing, eliminating the need to disassemble the flame arrestor in half for flame arrestor core replacement. The operation is simple and fast. Attached Figure Description

[0033] Continue as Figure 4 As shown, the side box 400 is fixedly installed on the outer side wall of the outer shell 100, and the cross-section of the side box 400 is set in a semi-circular arc structure.

[0034] like Figure 6 As shown, for the installation of two elastic limiting components 500, two openings 401 are provided on the side box 400, and two cavities 402 are provided between the side box 400 and the outer shell 100; the two elastic limiting components 500 are respectively disposed in the corresponding openings 401 and cavities 402 on the side box 400; the two elastic limiting components 500 are configured to clamp and fix the shell plate 300 on the outer shell 100 when they are close to each other; and to detach from the shell plate 300 when they are far apart; the elastic limiting components 500 include: a limiting plate 501 and several springs 502; the limiting plate 501 is movably installed in the corresponding openings 401 and cavities 402 on the side box 400, the cross-section of the limiting plate 501 is C-shaped, the limiting plate 501 limits and clamps the surface of the shell plate 300 on the outer shell 100, thereby limiting and fixing the position of the shell plate 300, and the limiting plate 501 has a T-shaped The handle, a T-shaped handle on the limiting plate 501, is accommodated inside the box opening 401 of the side box 400; one end of several springs 502 is fixedly installed on one side of the inner wall of the box cavity 402 inside the side box 400, and the other end of several springs 502 is fixedly installed on one side of the same limiting plate 501; by simultaneously adjusting the T-shaped handles on the two limiting plates 501, the installer can adjust the opposing sliding position of the two limiting plates 501 inside the side box 400. When the two limiting plates 501 are adjusted to move away from each other, the two limiting plates 501 are disengaged from the shell plate 300. At this time, several springs 502 on one side of the two limiting plates 501 are deformed and compressed under force, which makes it easy to remove the shell plate 300 from the shell opening 102; when several springs 502 on one side of the two limiting plates 501 are under natural elasticity, the two limiting plates 501 are fitted onto the outer wall of the shell plate 300 to limit and fix the position of the shell plate 300.

[0035] like Figure 5 and Figure 6As shown, in order to achieve stable opposing sliding of the two limiting plates 501 within the side box 400, the inner walls of the two limiting plates 501 are respectively provided with multiple limiting grooves 5011, and the outer walls of the outer shell 100 are respectively fixedly installed with several limiting strips 103. The several limiting strips 103 are respectively embedded in the corresponding limiting grooves 5011 on the limiting plates 501, so that the limiting plates 501 can slide stably opposite each other on the several limiting strips 103 on the outer walls of the outer shell 100.

[0036] like Figure 1 As shown, a support base 600 is fixedly installed on the bottom side of the outer casing 100, and the support base 600 provides support for the outer casing 100.

[0037] This application utilizes an annular groove 101 and a shell opening 102 on the outer casing 100 to sequentially embed and install the flame arrestor core 200 and the shell plate 300 onto the outer casing 100. The flame arrestor core 200 and the shell plate 300 are installed via a plug-in assembly. By simultaneously adjusting the T-shaped handles on the two limiting plates 501, the installer can adjust the opposing sliding positions of the two limiting plates 501 within the opposite box 400. When the two limiting plates 501 are adjusted to move away from each other, they disengage from the shell plate 300. At this time, several springs 502 on one side of the two limiting plates 501 are deformed and compressed, making it easy to remove the shell plate 300 from the shell opening 102. This facilitates quick inspection and replacement of the flame arrestor core 200 within the outer casing 100 without having to split the flame arrestor in half to inspect the flame arrestor core 200, making the operation simple and fast.
