Hydrogen sulfide is a toxic, flammable gas with a strong rotten egg smell that may be produced during coal mining due to the decomposition of sulfide minerals.

[0003] The existing alkaline aerosol spray device for separating and purifying hydrogen sulfide gas in coal mines usually sprays alkaline solution into the mine through a spray tank to purify the hydrogen sulfide gas. However, since the spray tank is usually fixed at a certain position in the mine, it is not easy to move to adapt to the hydrogen sulfide gas treatment needs in different areas of the mine, which is inconvenient.

[0004] Therefore, an alkaline aerosol spray device for separating and purifying hydrogen sulfide gas in coal mines has been developed to meet the hydrogen sulfide gas treatment needs of different areas of the mine. Summary of the invention

When the monorail crane moves, the connecting bracket is driven to move, so that the storage bottle moves along the track in the mine to spray the alkaline liquid, thereby achieving the effect of automatically moving the connecting bracket in the mine.

[0018] 3. In the present invention, after the solution is passed into the fixed pipe, it enters the connected hollow column from the fixed pipe, and the pressure of the alkaline liquid is enhanced by the second connected impeller. Then the alkaline liquid is passed into the rotating nozzle, and the first connected impeller is rotated, which drives the rotating nozzle to rotate, so that the rotating nozzle rotates to spray the alkaline liquid, thereby achieving the effect of expanding the spraying range of the alkaline solution and ensuring the complete treatment of the hydrogen sulfide gas in the mine.

[0019] 4. After the alkaline liquid is introduced into the storage bottle, the present invention starts the motor to drive the stirring column on the left to rotate, and drives the stirring column on the right to rotate through the belt, thereby achieving the effect of stirring the solution in the storage bottle and avoiding precipitation of the solution.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the spray mechanism 6 includes a connecting hose 60, a fixed tube 61, a connecting support frame 62, a handle 63, a rotating column 64, a single nozzle 65, a first guide tube 66 and a first spring 67. The connecting hose 60 is clamped on the front side of the lower part of the connecting tube 4, the front side of the connecting hose 60 is connected to the fixed tube 61, the left and right sides of the fixed tube 61 are connected to the connecting support frame 62, the rear lower side of the fixed tube 61 is connected to the handle 63, the front lower side of the fixed tube 61 is rotatably connected to the rotating column 64, the single nozzle 65 is connected to the rotating column 64, the rear of the single nozzle 65 is slidably connected to the first guide tube 66, and the first spring 67 is connected between the first guide tube 66 and the single nozzle 65.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, the fixing mechanism 7 includes a connecting bracket 70, a shoulder strap 71, a fixing column 72 and a rotating plate 73. The storage bottles 1 are fixed on the connecting bracket 70. The connecting tube 4 is connected to the connecting bracket 70. The front sides of the left and right parts of the connecting bracket 70 are connected to shoulder straps 71. The shoulder straps 71 are provided with cushions to improve the carrying comfort of the staff. The rear sides of the left and right parts of the connecting bracket 70 are connected to upper and lower fixing columns 72. The fixing columns 72 are rotatably connected to the rotating plates 73.

[0042] like Figure 1 and Fig.10 As shown, the moving mechanism 9 includes a fixed connecting frame 90, a fixed connecting column 91 and a moving roller 92. The fixed connecting frame 90 is connected to the rear side of the middle of the connecting bracket 70. The left and right sides of the fixed connecting frame 90 are connected to two upper and lower fixed connecting columns 91. The fixed connecting columns 91 are rotatably connected to the moving rollers 92. The moving rollers 92 are provided with anti-slip grooves to improve the moving stability.

[0043] When using the present invention, firstly, the storage bottle 1 is moved to the mine, then the valve 3 is turned to open, and the alkaline solution is passed into the storage bottle 1 through the inlet pipe 2. When it is necessary to purify the hydrogen sulfide gas in the mine, the connecting pump 5 is started to allow the alkaline solution to pass into the connecting pipe 4, and then sprayed into the mine from the connecting pipe 4. The alkaline solution (usually sodium hydroxide NaOH or other alkaline compounds) reacts chemically with the hydrogen sulfide gas to generate relatively harmless compounds, thereby purifying the hydrogen sulfide gas.

[0044] When there is wastewater in the mine, an inert gas can be introduced into the storage bottle 1, and then the connecting pipe 4 is placed in the wastewater, so that the storage bottle 1 introduces an inert gas into the wastewater, so as to bring the dissolved hydrogen sulfide out of the water surface and separate the hydrogen sulfide for easy collection and treatment. When the alkaline solution is introduced into the connecting pipe 4 and sprayed out, the connecting hose 60 can be docked with the connecting pipe 4, and then the rotating column 64 is rotated to drive the single nozzle 65 to rotate until the first guide tube 66 is docked with the fixed tube 61. The first guide tube 66 is pressed against the fixed tube 61 by the force of the first spring 67. After the alkaline solution is introduced into the connecting pipe 4, it passes through the connecting hose 60 and the fixed tube 61, and finally sprayed out from the single nozzle 65. The fixed tube 61 can be held by the handle 63 to move and spray the alkaline solution.

[0045] The fixed tube 61 can be fixed in the mine by connecting the support frame 62 to spray the alkaline solution. When the fixed tube 61 is held by the handle 63 to move and spray the alkaline solution, the worker can carry the connecting bracket 70 by the shoulder strap 71, and then carry the storage bottle 1 to move and spray the alkaline solution in the mine.

[0046] When the fixed pipe 61 is fixed in the mine by the connecting support frame 62 to spray the alkaline solution, the rotating plate 73 on the fixing column 72 can be rotated and adjusted, and then the connecting bracket 70 is fixed in the mine by the rotating plate 73 .

[0047] By using the moving mechanism 9 of the present device, the connecting bracket 70 can be automatically moved in the mine. When the distribution range of hydrogen sulfide gas in the mine is relatively wide, the fixed connecting bracket 90 is pushed into the moving track of the monorail crane in the mine, so that the moving roller 92 contacts the moving track, and then the connecting bracket 70 is fixed on the monorail crane. When the monorail crane moves, the connecting bracket 70 is driven to move, so that the storage bottle 1 moves along the track in the mine to spray the alkaline liquid, thereby playing a role in being able to adapt to the hydrogen sulfide gas treatment needs in different areas of the mine.

[0048] like Figure 1 , Figure 7 , Figure 8 and Fig. 9As shown, it also includes a diffusion mechanism 8, which includes a connecting rod 80, a rotating plate 81, a rotating nozzle 82, a first connecting impeller 83, a connecting hollow column 84, a second connecting impeller 85, a second guide tube 86 and a second spring 87. The upper side of the fixed tube 61 is connected to the connecting rod 80, the front side of the connecting rod 80 is rotatably connected to the rotating plate 81, the lower part of the rotating plate 81 is rotatably connected to the rotating nozzle 82, the inside of the rotating nozzle 82 is connected to the first connecting impeller 83, the rear side of the rotating nozzle 82 is rotatably connected to the connecting hollow column 84, the inside of the connecting hollow column 84 is connected to the second connecting impeller 85, the rear part of the connecting hollow column 84 is slidably connected to the second guide tube 86, and a second spring 87 is connected between the second guide tube 86 and the connecting hollow column 84.

[0049] By using the diffusion mechanism 8 of the present device, the spraying range of the alkaline solution can be expanded. When the storage bottle 1 moves, the rotating plate 81 on the connecting rod 80 is rotated to drive the connecting hollow column 84 to rotate until the second guide tube 86 is docked with the fixed tube 61. The second guide tube 86 is pressed against the fixed tube 61 by the action of the second spring 87. After the solution is passed into the fixed tube 61, it enters the connecting hollow column 84 from the fixed tube 61, and the alkaline liquid pressure is enhanced by the second connecting impeller 85. Subsequently, the alkaline liquid is passed into the rotating nozzle 82, causing the first connecting impeller 83 to rotate, driving the rotating nozzle 82 to rotate, so that the rotating nozzle 82 rotates to spray the alkaline liquid, thereby expanding the spraying range of the alkaline solution and ensuring that the hydrogen sulfide gas in the mine is completely treated.

[0050] like Figure 1 , Fig.11 and Fig.12 As shown, it also includes a stirring mechanism 10, which includes a motor 100, a stirring column 101 and a belt 102. The motor 100 is connected to the lower side of the storage bottle 1 on the left, and the stirring column 101 is rotatably connected to the lower part of the storage bottle 1. The output shaft of the motor 100 is connected to the stirring column 101 on the left, and the belt 102 is wound around the stirring columns 101 through a transmission wheel.

[0051] The stirring mechanism 10 of the device can be used to stir the solution in the storage bottle 1. After the alkaline liquid is introduced into the storage bottle 1, the motor 100 is started to drive the stirring column 101 on the left to rotate, and the stirring column 101 on the right to rotate is driven by the belt 102, thereby stirring the solution in the storage bottle 1 and preventing the solution from precipitating.

[0052] like Figure 1 and Fig.13As shown, it also includes a locking mechanism 11, which includes a rotating connecting frame 110 and a locking column 111. The rotating connecting frame 110 is rotatably connected to the rear of the connecting rod 80, and the locking column 111 is connected to the lower part of the rotating connecting frame 110. The locking column 111 is engaged with the second guide tube 86.

[0053] By using the locking mechanism 11 of the present device, the first guide tube 66 and the second guide tube 86 can be locked. When the first guide tube 66 or the second guide tube 86 is locked with the fixed tube 61, the rotating connecting frame 110 is rotated to make the locking column 111 lock with the first guide tube 66 or the second guide tube 86, thereby locking the first guide tube 66 and the second guide tube 86 and preventing the first guide tube 66 or the second guide tube 86 from being separated from the fixed tube 61.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
