Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature flashback prevention devices, specifically relating to a high-temperature flashback prevention device for a burner combustion-supporting pipeline. Background Technology

[0002] A burner is a general term for a device that sprays fuel and air out in a certain way to mix and burn. When a burner is used, it needs to be connected to and installed with a combustion-supporting pipe. The combustion-supporting pipe needs to be protected against high-temperature backfire. This is usually prevented by a high-temperature backfire prevention device. The existing high-temperature backfire prevention device is a device installed on the combustion-supporting pipe of the burner to prevent high-temperature backfire. Existing high-temperature flashback protection devices are installed on the burner combustion pipe and, during use, directly introduce compressed gas into the interior through the intake pipe and then eject it, using the ejected gas to flush the high-temperature gas back into the RTO furnace. Therefore, even though the compressed gas is compressed, residual dust and dirt still enter the interior, making filtration difficult. Prolonged exposure to dust and dirt can cause blockages, reducing the intake efficiency or even obstructing the flow, hindering effective high-temperature protection. This affects the convenience of using the high-temperature flashback protection device to filter compressed gas before it enters the burner combustion pipe. Therefore, this invention proposes a high-temperature flashback protection device for burner combustion pipes. Utility Model Content

[0003] The purpose of this utility model is to provide a high-temperature backfire prevention device for burner combustion pipelines, in order to solve the problem mentioned in the background art that when the high-temperature backfire prevention device is installed on the burner combustion pipeline, compressed gas can directly enter. Even if the gas is compressed, the compressed gas still leaves residual dust and dirt inside, which is not easy to filter. When dust and dirt enter for a long time, it can easily cause internal blockage, reduce the air intake effect, or even block it, making it impossible to effectively flush back the gas for high-temperature protection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature flashback prevention device for a burner combustion-supporting pipe, comprising a main body for the high-temperature flashback prevention device, the main body of the high-temperature flashback prevention device including a burner body, a combustion-supporting pipe body fixed to the bottom end of the burner body, a burner head fixed at the middle position of the combustion-supporting pipe body, an air inlet pipe fixed to one bottom end of the combustion-supporting pipe body, and a nozzle threadedly connected to the top end of the air inlet pipe inside the combustion-supporting pipe body; the main body of the high-temperature flashback prevention device also includes: A filtration mechanism, comprising an air intake mounting assembly disposed at the end of an air intake pipe, wherein a filtration assembly is disposed inside the air intake mounting assembly, and an air duct assembly is disposed on one side of the interior of the air intake mounting assembly; The protective mechanism includes a protective component disposed at the top of the nozzle, a fixed mounting component disposed on one side of the protective component on the inner surface of the combustion-supporting pipe body, and an elastic clamping component disposed at the connection between the fixed mounting component and the protective component.

[0005] Preferably, a manual valve is provided at one end of the air intake pipe, and a pressure regulating valve and an oil-water separator are sequentially provided at the bottom end of the air intake pipe.

[0006] Preferably, the intake mounting assembly includes a filter box fixedly installed at the end of the intake pipe, and the surface of the filter box is fixedly provided with an installation port.

[0007] Preferably, the filter assembly includes a fixed cover plate that is fixedly mounted on the surface of the filter box by screws, and a coarse filter screen and a fine filter screen are fixed on the lower surface of the fixed cover plate.

[0008] Preferably, the air intake assembly includes air intake ramps formed on both sides of one end inside the filter box, and the two air intake ramps are symmetrically arranged.

[0009] Preferably, the protective component includes a protective cover plate disposed at the top of the nozzle, and the protective cover plate has a ring structure.

[0010] Preferably, the fixed installation assembly includes two fixed base plates fixedly installed at the bottom of one side inside the combustion-supporting pipe body, and the end of the protective cover plate is integrally provided with a connecting block, which extends into the interior of the two fixed base plates.

[0011] Preferably, the elastic clamping assembly includes a connecting shaft disposed at the connection between the connecting block and the fixed base plate, and a torsion spring is fitted onto the outer surface of the connecting shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By designing a filtration mechanism, compressed gas can enter the filter box through the installation port, be filtered by coarse and fine filters, and then be drawn into the intake pipe by the induced draft slope. The compressed air is then quickly ejected into the nozzle through the intake pipe. This design prevents dust and dirt from entering the intake pipe and connected components, thus reducing clogging and facilitating the smooth filtration of compressed gas before high-temperature flashback protection. This also improves the convenience of installing the high-temperature flashback protection device on the combustion-supporting pipe body for filtering compressed gas before it enters.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 6 This utility model provides a technical solution: a high-temperature flashback prevention device for a burner combustion-supporting pipe, comprising a main body 100, a burner body 101, a combustion-supporting pipe body 102 fixed to the bottom end of the burner body 101, a burner head 103 fixed at the middle position of the combustion-supporting pipe body 102, an air inlet pipe 104 fixed to one side of the bottom end of the combustion-supporting pipe body 102, a nozzle 106 threadedly connected to the top end of the air inlet pipe 104 inside the combustion-supporting pipe body 102, a manual valve 107 provided at one end of the air inlet pipe 104, and a pressure regulating valve 108 and an oil-water separator 105 sequentially provided at the bottom end of the air inlet pipe 104. The main body 100 of the high-temperature flashback prevention device also includes: The filter mechanism includes an air intake mounting assembly located at the end of the air intake pipe 104. The air intake mounting assembly contains a filter assembly, and an air duct assembly is located on one side of the air intake mounting assembly. When the main body 100 of the high-temperature flashback protection device is installed and used, after the compressed gas enters, the compressed gas is filtered by the filter mechanism and then flushed out again for high-temperature flashback protection.

[0016] In order to facilitate air intake filtration through the air intake mounting assembly, in this embodiment, preferably, the air intake mounting assembly includes a filter box 1041 fixedly installed at the end of the air intake pipe 104. The surface of the filter box 1041 is fixed with an installation port 1042, so that air can be introduced into the filter box 1041 after being connected and installed through the installation port 1042, which facilitates air intake filtration.

[0017] In order to facilitate the filtration of compressed gas after it enters the filter box 1041, in this embodiment, preferably, the filter assembly includes a fixed cover plate 1043 that is fixedly installed on the surface of the filter box 1041 by screws. The lower surface of the fixed cover plate 1043 is fixed with a coarse filter screen 1044 and a fine filter screen 1045, so that the compressed gas entering the filter box 1041 can be filtered by the coarse filter screen 1044 and the fine filter screen 1045, and then flushed out of the air intake pipe 104 after filtration.

[0018] In order to facilitate the high-temperature backfire prevention treatment of the filtered compressed air material entering the air intake pipe 104 through the air intake assembly, in this embodiment, preferably, the air intake assembly includes air intake ramps 1046 formed on both sides of one end inside the filter box 1041, and the two air intake ramps 1046 are symmetrically arranged. After filtering the compressed gas, the air can be drawn into the air intake pipe 104 through the air intake ramps 1046 and concentrated into the air intake for flushing treatment.

[0019] The protective mechanism includes a protective component installed at the top of the nozzle 106. A fixed installation component is installed on one side of the protective component on the inner surface of the combustion-supporting pipe body 102. An elastic clamping component is installed at the connection between the fixed installation component and the protective component. After the nozzle 106 stops expelling compressed gas, the protective mechanism can close and protect the top of the nozzle 106, making it less likely for dust to fall into the end of the nozzle 106 and cause blockage. It can then be used to expel compressed gas effectively again.

[0020] In order to facilitate the protection of the top of the nozzle 106 through the protective component, and to prevent the nozzle 106 from being exposed to the outside world and falling into dust when not in use, in this embodiment, preferably, the protective component includes a protective cover plate 1061 disposed on the top of the nozzle 106, and the protective cover plate 1061 has a ring structure, so that when not in use, the protective cover plate 1061 can be pressed tightly closed to protect the top of the nozzle 106, and the end of the nozzle 106 is not easily blocked.

[0021] In order to facilitate the installation and use of the protective cover 1061 by means of a fixed installation component, in this embodiment, preferably, the fixed installation component includes two fixed base plates 1062 fixedly installed at the bottom end of one side inside the combustion-supporting pipe body 102. The end of the protective cover 1061 is integrally provided with a connecting block 1063, and the connecting block 1063 extends into the interior of the two fixed base plates 1062, so that it can be conveniently installed and opened or closed at the connection between the fixed base plate 1062 and the connecting block 1063.

[0022] In order to facilitate the elastic compression and closure of the protective cover 1061 by means of the elastic compression assembly, in this embodiment, preferably, the elastic compression assembly includes a connecting shaft 1064 disposed at the connection between the connecting block 1063 and the fixed base plate 1062. A torsion spring 1065 is fitted and installed on the outer surface of the connecting shaft 1064. After the compressed gas on the protective cover 1061 disappears, the deformation of the torsion spring 1065 will drive the connecting shaft 1064 and the protective cover 1061 to be tightly compressed and closed on the surface of the nozzle 106 for protection.

[0023] The working principle and usage process of this utility model: When the combustion pipe of this burner is backfired, the nozzle 106 automatically opens due to the high temperature, connecting the installation port 1042 to the end of the external compressed gas and allowing it to enter the filter box 1041 until it enters the air inlet pipe 104. The compressed air pushes the high-temperature gas into the burner body 101. The pressure regulating valve 108 can adjust the air pressure to ensure that the compressed air can push the high-temperature gas back into the burner body 101. At the same time, the installation of the manual valve 107 can ensure that the compressed air does not leak during maintenance, which is energy-saving and environmentally friendly. Then, when the main body 100 of the high-temperature flashback protection device is in use during installation, compressed air enters the filter box 1041 through the installation port 1042. After entering the filter box 1041, the compressed air is filtered by the coarse filter screen 1044 and the fine filter screen 1045. After the compressed air is filtered, it is again drawn into the air intake pipe 104 by the induced draft slope 1046. This facilitates the rapid entry of the compressed air into the nozzle 106 for spraying. Therefore, the compressed air is easily filtered when it enters the air intake pipe 104, and it is not easy for dust and dirt to enter the air intake pipe 104 and the connected parts, so it is not easy to block. This facilitates the smooth filtration of the compressed gas for high-temperature flashback protection, and improves the convenience of the main body 100 of the high-temperature flashback protection device for filtering the compressed gas before it enters the combustion pipe main body 102. Finally, when the main body 100 of the high-temperature flashback protection device is installed and in use, compressed gas enters through the air inlet pipe 104 and is ejected through the nozzle 106. When the compressed gas is ejected, it directly applies pressure to the protective cover plate 1061 and automatically opens it. When the protective cover plate 1061 is opened, the compressed gas is ejected through the nozzle 106 to prevent high-temperature flashback. When not in use, when the end of the nozzle 106 is not ejecting compressed gas, the deformation of the torsion spring 1065 drives the connecting shaft 1064 to rotate and elastically presses the connecting block 1063 and the protective cover plate 1061 together. This makes the protective cover plate 1061 press tightly against the surface of the nozzle 106 for protection. When not in use, it is easy to press and protect, and it is not easy for dirt to enter the interior of the nozzle 106. This facilitates the use of pressing and protecting, and improves the convenience of protecting the end of the nozzle 106 when the main body 100 of the high-temperature flashback protection device is installed on the combustion-supporting pipe main body 102 and is not in use.
