It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0028] In order to solve the technical problem that the sealing device in the prior art cannot block the flame from spraying the sealing position when the flame is not needed, the utility model provides a kind of flame sealing device, which can be realized in the flame of blocking when the flame is not needed and sprays the sealing position.

[0029] It should be noted that the sealing flame device is used for but not limited to sealing device and the like, in order to facilitate the description, in the utility model, only take the sealing flame device is applied to the sealing equipment as an example to illustrate, and the principle of the sealing flame device is applied to other types of equipment and the principle of the sealing equipment is substantially the same, and here is not described one by one.

[0030] Please refer to Figure 1 And Figure 2 , Figure 1 It is the structure diagram of the sealing flame device in an embodiment of the utility model, Figure 2 It is Figure 1 The local enlarged diagram of A in the figure, the sealing flame device includes rack 1, fire spraying assembly 2 and airflow assembly 3, fire spraying assembly 2 is connected rack 1, it has the fire spraying end of spraying fire; airflow assembly 3 is connected rack 1, and has the blowing end for blowing airflow, the blowing direction of airflow assembly 3 and the flame jet direction of fire spraying assembly 2 cross.

[0031] Specifically, fire spraying assembly 2 sprays flame through the fire spraying end, heats the test tube through the sprayed flame, so that the test tube is heated and softened, to facilitate sealing; when installing new test tube to be sealed and removing the test tube sealed, the flame needs to be avoided to spray to the test tube sealing area, for this, start airflow assembly 3, the blowing end of airflow assembly 3 blows airflow, the blown airflow and the flame jet direction of fire spraying assembly 2 cross, the blowing airflow changes the jet direction of flame, so that the jet direction of flame deviates from the test tube sealing area, the jet direction of flame can be changed without flame; when the test tube needs to be sealed, airflow assembly 3 is closed, at this time, airflow assembly 3 stops blowing airflow, so that the flame sprayed by fire spraying assembly 2 can contact the test tube, and sealing is carried out.

[0032] It should be understood that rack 1 can be a support formed by splicing various types of profiles, or an integrally formed rack 1, etc.; fire spraying assembly 2 can be a flame heater, a flame jet lamp, etc.

[0033] It should be understood that airflow assembly 3 can be a pipeline, a nozzle 31, etc. that can blow air, specifically, in one embodiment, airflow assembly 3 includes a nozzle 31 and a gas source (not shown in the figure), the nozzle 31 is connected to the rack 1, and the gas outlet end of the gas source is in communication with the air inlet end of the nozzle 31.

[0034] When the airflow needs to be blown out, the gas source passes the gas into the nozzle 31, and the gas curtain is formed by the concentrated spraying of the nozzle 31, and the jet direction of the flame is changed by the gas curtain.

[0035] It should be understood that the gas source can be a gas supply pipeline, an air compressor, etc.

[0036] It should be understood that the nozzle 31 can be of various shapes and structures, specifically, such as Figure 2 As shown, in one embodiment, the blowing end of the nozzle 31 is flat, and the blowing direction of the blowing end of the nozzle 31 is perpendicular to the flame jet direction of the flame jet assembly 2.

[0037] In this embodiment, the nozzle 31 is flat, which pressurizes the airflow when it is ejected from the nozzle 31, forming a strong airflow to change the direction of the flame jet. At the same time, the flat blowing end can form a flat air curtain, and the direction of the air curtain is perpendicular to the direction of the flame jet. The air curtain can block and change the direction of the flame jet.

[0038] When the flame jet direction changes, the direction of heat dissipation during combustion also changes. To prevent heat from damaging other equipment, therefore, such as Figure 2 As shown, in one embodiment, the airflow assembly 3 further includes an exhaust pipe 32, which is connected to the frame 1. The exhaust pipe 32 and the nozzle 31 are disposed on both sides of the flame-spraying assembly 2, and the air inlet end of the exhaust pipe 32 faces the blowing direction of the nozzle 31.

[0039] In this embodiment, the exhaust pipe 32 can receive the flame blown out by the exhaust pipe 32, guide the heat to flow to a designated location, and extinguish the flames that change direction.

It should be understood that the exhaust hood 33 can also be connected to the exhaust system in the factory to discharge the exhaust gas generated during combustion from the factory.

[0042] To further reduce the risk of burns from flames, such as Figure 2 and Figure 3 As shown, in one embodiment, the sealing flame device further includes a baffle assembly 4, which includes a baffle 41. The baffle 41 is movably connected to the frame 1 and can move to the flame-spraying end of the flame-spraying assembly 2, and can also move away from the flame-spraying end of the flame-spraying assembly 2.

[0043] In this embodiment, a baffle 41 is provided. The baffle 41 is movably connected to the frame 1 and can be moved or detached from the flame-spraying end of the flame-spraying assembly 2. The baffle 41 can block the sprayed flame and prevent the flame from spraying towards the test tube sealing area, thereby reducing the risk of burning. When sealing is required, the baffle 41 is removed from the flame-spraying end of the flame-spraying assembly 2.

[0044] Because the flame temperature ejected by the flame jetting assembly 2 is high, if the baffle 41 is in contact with the flame for a long time, the service life of the baffle 41 will be greatly shortened. Therefore, in one embodiment, when the baffle 41 is moved to the flame jetting end of the flame jetting assembly 2, the baffle 41 is located on the side of the air blowing end of the air flow assembly 3 away from the flame jetting assembly 2.

[0045] In the embodiment, the baffle 41 only plays a blocking role, and the flame is only changed in direction by the air flow blown by the air flow assembly 3, which greatly reduces the contact between the baffle 41 and the flame and prolongs the service life of the baffle 41.

[0046] In order to drive the baffle 41 to move away from or away from the flame jetting end of the flame jetting assembly 2, the baffle assembly 4 further comprises a moving piece 42 connected to the rack 1 and having a moving end capable of moving in three mutually perpendicular directions relative to the rack 1, and the moving end is connected to the baffle 41.

[0049] The moving piece 42 can be directly connected to the baffle 41, or can be connected to the baffle 41. Specifically, as shown in Figure 3 and Figure 4 In one embodiment, the baffle assembly 4 further comprises a connecting piece 43 connected to the moving end of the moving piece 42, the baffle 41 is detachably connected to the connecting piece 43, and the baffle 41 is connected to the moving end of the moving piece 42 through the connecting piece 43.

[0050] The connecting piece 43 realizes the connection between the baffle 41 and the vertical moving end, and at the same time, the connecting piece 43 is detachably connected to the baffle 41, so that the baffle 41 is detached from the connecting piece 43 for replacement.

[0051] It should be understood that the connecting piece 43 can be a connecting bracket, a connecting rod, a connecting strip, etc. Specifically, as shown in Figure 4 ​As shown, in one of the embodiments, the connecting piece 43 comprises a connecting arm 431 connected with the moving end of the moving piece 42, and a clamping plate 432 detachably connected with the connecting arm 431, and a clamping gap for clamping the baffle 41 is formed between the clamping plate 432 and the connecting arm 431.
