However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] The effect achieved by the entire Embodiment 1 is that when the drying and purifying device of the tugboat pneumatic control system is in use, by fixedly arranging a fixing sleeve 2 on the outer surface of the air bottle 1, a box body 301 is fixedly connected to its top. Pull the movable frame 303 upward, and a plurality of sliders 304 fixed on both sides of the movable frame 303 slide synchronously along the surfaces of a plurality of sliding rods 305. The plurality of sliding rods 305 are located inside a plurality of limiting grooves 308. When the sliders 304 move upward, they will squeeze a plurality of springs 306, causing them to deform and contract, and then the movable frame 303 slides out from the top of the cover plate 302, facilitating personnel to put the desiccant 309 into the movable frame 303. Slowly relax the pulling of the movable frame 303. Under the elastic reset action of the springs 306, the movable frame 303 slides downward and resets along the outer surfaces of the plurality of sliding rods 305. Start the compressor 4. The compressor 4 inhales the gas inside the box body 301 through the connecting pipe 5, generating negative pressure inside it. Under the action of the negative pressure, external air penetrates the holes on the surface of the filter screen 311 and is inhaled into the box body 301. The impurities in the air will be blocked and filtered by the filter screen 311, and when passing through the desiccant 309, the moist moisture in the air will be absorbed by the desiccant 309, forming clean and dry gas, which is stored in the air bottle 1 along the connecting pipe 5 and the compressor 4. When it is not necessary to purify the air, close the valve on the surface of the connecting pipe 5 and open the valve on the surface of the bypass pipe 6, so that the compressor 4 will directly inhale external air and compress it, storing it in the air bottle 1. By fixedly arranging a purification component 3 on the surface of the air bottle 1, when the air bottle 1 stores air, dust and impurities are filtered by the filter screen 311, and the desiccant 309 absorbs the moist moisture in the air, playing a purification role, so that the gas stored in the air bottle 1 is relatively dry, avoiding that after there is more moisture remaining inside the air bottle 1, when entering each system through the control air cylinder, the stored air contains more impurities and moisture, which is likely to damage the internal electronic components of each system.

[0027] Embodiment 2: As Figures 1-6 shown, a bolt 312 is arranged at the center of the front surface of the internally threaded block 310. The outer surface of the bolt 312 sequentially passes through the outer surfaces of the internally threaded block 310 and the filter screen 311 in a movable manner. A wing nut 313 is threadedly rotated and connected to the outer surface of the bolt 312 near the rear end surface. The outer surface of the filter screen 311 fits with the inner surface of the internally threaded block 310.

[0028] The effect achieved by the entire Embodiment 2 is that when disassembling the filter screen 311, rotate the internally threaded block 310 clockwise to separate it from the threaded ring block 307, fix the bolt 312, and manually rotate the wing nut 313 to separate it from the bolt 312, facilitating personnel to remove the filter screen 311 for cleaning or replacement, thereby avoiding a large amount of dust and impurities adhering to the surface of the filter screen 311 and affecting the filtering effect, with high practicability.

[0029] Working principle: When the drying and purifying device of the tugboat pneumatic control system is in use, a fixed sleeve 2 is fixedly arranged on the outer surface of the air bottle 1, and a box body 301 is fixedly connected to its top. Pull the movable frame 303 upward, and a plurality of sliders 304 fixed on both sides of the movable frame 303 slide synchronously along the surfaces of a plurality of sliding rods 305. A plurality of sliding rods 305 are located inside a plurality of limiting grooves 308. When the sliders 304 move upward, they will squeeze a plurality of springs 306, causing them to deform and contract, and then the movable frame 303 slides out from the top of the cover plate 302, facilitating personnel to put the desiccant 309 into the movable frame 303. Slowly relax the pulling of the movable frame 303. Under the elastic reset action of the springs 306, the movable frame 303 slides downward and resets along the outer surfaces of the plurality of sliding rods 305. Start the compressor 4. The compressor 4 inhales the gas inside the box body 301 through the connecting pipe 5, generating negative pressure inside it. Under the action of the negative pressure, the external air penetrates the holes on the surface of the filter screen 311 and is inhaled into the box body 301. The impurities in the air will be blocked and filtered by the filter screen 311, and when passing through the desiccant 309, the moist moisture in the air will be absorbed by the desiccant 309, forming clean and dry gas, which is stored in the air bottle 1 along the connecting pipe 5 and the compressor 4. When it is not necessary to purify the air, close the valve on the surface of the connecting pipe 5 and open the valve on the surface of the bypass pipe 6, so that the compressor 4 will directly inhale the external air and compress it, storing it in the air bottle 1. By fixedly arranging the purification component 3 on the surface of the air bottle 1, when the air bottle 1 stores air, the dust and impurities are filtered by the filter screen 311, and the desiccant 309 absorbs the moist moisture in the air, playing a purification role, so that the gas stored in the air bottle 1 is relatively dry. To avoid that after there is more moisture remaining inside the air bottle 1 and then entering each system through the control air bottle, the stored air contains more impurities and moisture, which is likely to damage the internal electronic components of each system. When disassembling the filter screen 311, rotate the internal thread block 310 clockwise to separate it from the thread ring block 307, fix the bolt 312, and manually rotate the wing nut 313 to separate it from the bolt 312, facilitating personnel to remove the filter screen 311 for cleaning or replacement, thereby avoiding more dust and impurities adhering to the surface of the filter screen 311 and affecting the filtering effect, with high practicability.
