[0021] Specifically, a pressure gauge 6 is arranged at the front side of the upper end of the gas storage tank 1, the pressure gauge 6 is connected to the gas storage tank 1 through a thread, and a rubber sealing ring is arranged between the pressure gauge 6 and the gas storage tank 1.

[0022] By adopting the above technical solution, the pressure gauge 6 is provided to monitor the air pressure inside the gas storage tank 1. When the pressure inside the gas storage tank 1 is insufficient, the air inflation pump 3 can be turned on to inflate the gas storage tank 1.

[0023] Specifically, both between the steel plate 8 and the purging pipe 7 and between the connecting hopper 9 and the purging pipe 7 are welded by spot welding, and the flat pipe 10 and the connecting hopper 9 are of a welded integral structure.

[0024] By adopting the above technical solution, spot welding makes the connection between the steel plate 8 and the purging pipe 7 and between the connecting hopper 9 and the purging pipe 7 more firm, and the welded integral structure of the flat pipe 10 and the connecting hopper 9 is more durable.

[0025] When this embodiment is in use, when the desulfurization system pipeline purging device is in use, the device is installed at a suitable position. By setting the purging pipe 7, a hole is opened at a suitable position of the inlet elbow of the dust collector, one end of the flat pipe 10 of the purging pipe 7 is inserted, and then the steel plate 8 on the purging pipe 7 is fixed to the inlet elbow of the dust collector by welding. The air inflation pump 3 inflates the air storage tank 1 through the air inflation pipe 4. The valve 11 is opened, and the high-pressure air in the air storage tank 1 enters the purging pipe 7 through the rubber pipe 13. The flat pipe 10 at one end of the purging pipe 7 blows air into the inlet elbow of the dust collector for purging work. The setting of the flat pipe 10 can increase the purging pressure. By setting the purging pipe 7, the inside of the inlet elbow of the dust collector can be purged, reducing the risk of material blockage.

[0026] Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that: the sealing assembly 2 includes a baffle 21, a folding plate 22, a rotating seat 23, a first magnetic block 24, a second magnetic block 25 and a limiting plate 26. Among them, two folding plates 22 are arranged on one side of the upper end of the flat pipe 10, a rotating seat 23 is arranged between the two folding plates 22, a baffle 21 is arranged at one end of the rotating seat 23, a first magnetic block 24 is arranged at one end of the baffle 21, and a second magnetic block 25 is arranged at a position corresponding to the first magnetic block 24 at one end of the flat pipe 10. A limiting plate 26 is arranged at the upper end of the folding plate 22.

[0028] By adopting the above technical solution, when the device is in use, the rotating seat 23 at one end of the baffle 21 is blown by the air blown by the flat pipe 10 and rotates on the folding plate 22. The baffle 21 is opened to carry out the purging work. At the same time, the limiting plate 26 at the upper end of the folding plate 22 can limit the baffle 21. When the device is not in use, the baffle 21 resets due to the action of gravity. The first magnetic block 24 on the baffle 21 adsorbs the second magnetic block 25 at one end of the flat pipe 10, achieving the effect of adsorbing and fixing the baffle 21. The baffle 21 can seal one end of the flat pipe 10 to prevent materials from entering the flat pipe 10.

[0029] Specifically, the rotating seat 23 is rotatably connected to the folding plate 22 through a shaft pin, and the rotating seat 23 and the baffle 21 are of an integrally welded structure.

[0030] By adopting the above technical solution, the rotating seat 23 can rotate on the folding plate 22, and the integrally welded structure of the rotating seat 23 and the baffle 21 is more solid.

[0031] Specifically, the side of the first magnetic block 24 and the side of the baffle 21 are flush, and the side of the second magnetic block 25 and the side of the flat pipe 10 are flush. The baffle 21 is made of an aluminum structure.

[0032] By adopting the above technical solution, the baffle 21 fits more closely to the flat pipe 10 after being closed. The baffle 21 made of an aluminum structure is lighter and more convenient to use.

[0033] When this embodiment is in use, by setting the sealing component 2, when the device is in use, the blowing air from the flat tube 10 blows the rotating seat 23 at one end of the baffle 21 to rotate on the folding plate 22, and the baffle 21 opens to carry out the purging work. At the same time, the limiting plate 26 at the upper end of the folding plate 22 can play a limiting role on the baffle 21. When the device is not in use, the baffle 21 resets due to gravity, and the magnet one 24 on the baffle 21 adsorbs with the magnet two 25 at one end of the flat tube 10, achieving the effect of adsorbing and fixing the baffle 21. The baffle 21 can seal one end of the flat tube 10 to prevent materials from entering the flat tube 10.

[0034] The air inflation pump 3 in the present utility model is a publicly known prior art, and the selected model is OTS-750x3-65L.

[0035] The working principle and usage process of the present utility model: When the desulfurization system pipeline purging device is in use, the device is installed at a suitable position.

The air inflation pump 3 inflates the air storage tank 1 through the air inflation pipe 4. The valve 11 is opened, and the high-pressure air in the air storage tank 1 enters the purging pipe 7 through the rubber pipe 13. The flat tube 10 at one end of the purging pipe 7 blows air into the inlet elbow of the dust collector to carry out the purging work. The setting of the flat tube 10 can increase the purging pressure. By setting the purging pipe 7, the inside of the inlet elbow of the dust collector can be purged, reducing the risk of material blockage. By setting the sealing component 2, when the device is in use, the blowing air from the flat tube 10 blows the rotating seat 23 at one end of the baffle 21 to rotate on the folding plate 22, and the baffle 21 opens to carry out the purging work. At the same time, the limiting plate 26 at the upper end of the folding plate 22 can play a limiting role on the baffle 21. When the device is not in use, the baffle 21 resets due to gravity, and the magnet one 24 on the baffle 21 adsorbs with the magnet two 25 at one end of the flat tube 10, achieving the effect of adsorbing and fixing the baffle 21. The baffle 21 can seal one end of the flat tube 10 to prevent materials from entering the flat tube 10.
