Description

[0001] The present disclosure belongs to the field of flame arresters, and particularly relates to a flame arrestor disc assembly structure resistant to long-time combustion. Background Art

[0002] The flame arrestor disc is the valve core of the flame arrester. The flame arrestor disc is now widely used in the fields of petroleum, natural gas and many chemical industries. The flame arrestor disc is generally installed in the pipeline for transporting combustible gas or on the ventilated oil tank or oil storage tank, and is a device used to prevent the propagation of flame, deflagration or detonation.

[0003] When a fire occurs in the pipe, such as a flame arrestor disc and a flame arrester with the application number 202023014803.2, in order to improve the sealing performance, multiple shells are tightly connected by flanges, making the inside of the flame arrestor core closed, resulting in difficulty in dissipating the internal heat to the outside. The closed structure inside the flame arrestor disc makes the heat dissipation speed slow, and dissipating the heat into the external environment through the heat sink will cause the temperature of the external environment to rise. Since the fire occurs for a long time, the subsequent heat dissipation capacity is weakened. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0029] According to the concept of the present application, an embodiment of a flame arrestor disk assembly structure with long-term combustion resistance will be described herein in conjunction with Figures 1 to 5 Specifically, the flame arrestor disk assembly structure is configured as a split structure, which has three components: a main body shell 1, a heat dissipation disk 2, and a water-cooling component. By tightly connecting the heat dissipation disk 2 with the main body shell 1, heat is conducted through solids to the outside of the heat dissipation disk 2, thereby accelerating the heat dissipation speed inside the flame arrestor core 13. The heat energy transferred to the heat dissipation disk 2 is quickly transferred to the coolant by the water-cooling component 3. Due to the continuous replacement of the coolant, the decline in the heat dissipation capacity of the heat dissipation device caused by the environmental impact can be avoided, thereby improving the long-term combustion resistance of the flame arrestor disk.

[0030] Please refer to Figures 1 to 5, A fireproof disk assembly structure resistant to long-time combustion, comprising: a water-cooling assembly 3 for storing and guiding the flow of coolant. A heat dissipation disk 2 is coaxially and fixedly connected to the outer side of the main body shell 1. The heat dissipation disk 2 is used for conducting the heat inside the main body shell 1. A plurality of the heat dissipation disks 2 are arranged at equal intervals along the axial direction, and multiple groups of fixing holes 21 are circumferentially distributed on the heat dissipation disk 2. The water-cooling assembly 3 is located on the outer side of the main body shell 1, and the water-cooling assembly 3 includes a water storage tank 31 and connecting pipes 32. The water storage tank 31 is stacked and clamped on both sides of the plurality of heat dissipation disks 2, and a plurality of connecting pipes 32 are inserted into both sides of the water storage tank 31;

[0031] Adjacent two groups of water storage tanks 31 are inserted into the fixing holes 21 inside the heat dissipation disk 2 through the protrusions on both sides, so that the water-cooling assembly 3 and the heat dissipation disk 2 are stacked and clamped for installation. In this way, the heat on the heat dissipation disk 2 is transferred to the water-cooling assembly 3 through solid conduction. Solid conduction can accelerate the conduction speed, and at the same time, a large amount of heat energy is quickly carried out of the device by the coolant, thereby being able to reduce the heat on the heat dissipation disk 2.

[0032] Four mounting holes are circumferentially distributed on the outer wall of the main body shell 1, and the heat dissipation disk 2 is fixed to the main body shell 1 by bolts passing through the mounting holes, which can make the connection between the main body shell 1 and the heat dissipation disk 2 stable. The detachable connection by bolts facilitates the replacement of the heat dissipation disk 2.

[0033] A plurality of groups of heat dissipation disks 2 are provided to increase the contact area between the main body shell 1 and the outside world, thereby increasing the heat dissipation area, which is beneficial to preventing heat from being transferred to the protected side without reducing the internal pores of the fireproof core 13.

[0034] The water-cooling assembly 3 is inserted inside the fixing holes 21 to limit the position of the water storage tank 31 and prevent it from shaking. By providing a plurality of groups of water storage tanks 31 and connecting pipes, it is used to increase the contact area between the heat dissipation disk 2 and the water-cooling assembly 3, thereby improving the heat transfer speed between the coolant and the heat dissipation disk 2. And the plurality of groups of water storage tanks 31 and the connecting pipes 32 are in a communicating structure, which can improve the flexibility of the coolant flow.

[0035] A through hole 15 is provided through the center of the heat dissipation disc 2, and the diameter of the through hole 15 is equal to the diameter of the outer wall of the main body shell 1, so that the inner wall of the heat dissipation disc 2 is closely attached to the outer wall of the main body shell 1, so that heat is conducted with the solid as the medium. When a fire occurs inside the pipe, it is prevented that the inside of the fire retardant core is closed, resulting in difficult heat dissipation inside, which can accelerate the heat dissipation speed of the device. A fixing frame 11 is fixedly provided in the center of the inner side of the main body shell 1, and a plurality of fixing discs 14 are equidistantly arranged on the outer wall of the main body shell 1. The heat dissipation disc 2 is clamped by the fixing discs 14 and fixed by bolts, and the two groups of fixing discs 14 corresponding to the left and right sides of the heat dissipation disc 2 are closely attached, similar to the fixing of a flange ring, which can improve the connection stability between the heat dissipation disc 2 and the main body shell 1. A bolt 12 is provided through the center of the inner side of the fixing frame 11, and a fire retardant core 13 is inserted outside the bolt 12. The fire retardant core 13 is fixed by inserting the bolt 12 into the fire retardant core 13 and the fixing frame 11, which is used to fix the position of the fire retardant core 13 and improve the stability of the device. The main body shell 1, the fixing frame 11 and the fixing discs 14 are all die-cast integrated structures, which can further improve the stability of the device and can improve the heat resistance of the device, avoiding breakage at the connection when the temperature rises.

[0036] A plurality of water storage tanks 31 are arranged around the bolt 12, and a communication structure is formed between the plurality of water storage tanks 31 through a connecting pipe 32, which is used to reduce the water source interface and is beneficial to improving the convenience of the device. The outer walls on the upper and lower sides of the water storage tank 31 are set as arc surfaces, and the outer wall of the water storage tank 31 is attached to the inner wall of the fixing hole 21, increasing the contact area between the water storage tank 31 and the connecting pipe 32 and the heat dissipation disc 2, which is beneficial to increasing the heat conduction area between the coolant and the heat dissipation disc 2, and thus is beneficial to improving the heat dissipation speed of the heat dissipation disc 2. Limiting protrusions 5 are fixed at both ends of the connecting pipe 32, and a connecting port 4 is engaged outside the limiting protrusions 5. By inserting the connecting pipe 32 into the connecting port 4, the assembly is completed. The limiting protrusions 5 and the connecting port 4 are similar to buckles. When inserted, the limiting protrusions 5 undergo plastic deformation so that the connecting pipe 32 is fixed inside the water storage tank 31. By this method, it is convenient to disassemble the water cooling component 3. When scale is generated inside, it can be quickly disassembled and cleaned. An inlet 6 is provided through the front end of the water storage tank 31, and an outlet 7 is provided through the rear end of the water storage tank 31, and both the inlet 6 and the outlet 7 are connected to the external water source through water pipes, so that the coolant is always in a flowing state, which can avoid the decrease in the heat dissipation capacity of the device itself when the external environmental temperature rises, thereby improving the long-time combustion resistance ability of the fire retardant disc.

[0037] The following further describes the structure of a fire retardant disc assembly with long-time combustion resistance provided by the present invention in conjunction with the drawings and embodiments.

[0038] During use, the heat dissipation disk 2 is installed between two adjacent fixed disks 14 and fixed by bolts. At the same time, the fixing holes 21 inside multiple heat dissipation disks 2 are kept parallel, and multiple water storage tanks 31 are sequentially inserted into the pores of the fixing holes 21. Then, the connecting pipe 32 is inserted into the inner side of the connecting port 4 until the limiting protrusion 5 completely enters the inner cavity of the water storage tank 31, and multiple groups of water storage tanks 31 and connecting pipes 32 are sequentially fixedly connected to form multiple groups of annular sealing structures, thereby fixing the water storage tanks 31. Then, water pipes are inserted on the outer sides of the water inlet 6 and the water outlet 7 and connected to an external water source. During use, the temperature inside the pipe rises sharply, and the tiny flames inside come into contact with the inner wall of the flame retardant core 13, thereby transferring the heat to the flame retardant core 13. Since the flame retardant core 13 is closely attached to the main body shell 1 and the heat dissipation disk 2, the heat is quickly transferred to the heat dissipation disk 2 through solid conduction. During the process of the coolant flowing inside the connecting pipe 32 and the water storage tank 31, it can take away the heat on the heat dissipation disk 2, thereby accelerating the heat dissipation speed of the heat dissipation disk 2 itself. And due to the rapid flow of the coolant, it can prevent the heat dissipation capacity of the device itself from decreasing after the external environmental temperature rises, thereby improving the ability of the flame retardant disk to withstand long-term combustion.
