Description

Technical Field

[0001] The present invention belongs to the technical field of high-pressure gas cylinders, and in particular relates to a high-pressure gas cylinder. Background Art

[0002] In the manufacturing industry, high-pressure gas storage tanks are important equipment in the gas source system. For example, in the auxiliary equipment of bottle blowing machines, high-pressure gas storage tanks can store high-pressure air to solve the contradiction of short-term gas consumption in the system, and provide temporary emergency use in the event of air compressor failure or power outage. They can also eliminate or reduce the pulsation of the piston air compressor's output airflow, stabilize the gas source pressure, ensure continuous and stable output airflow, provide larger system capacity, extend the cycle of starting, stopping, loading and unloading of the air compressor, reduce the switching frequency of electrical equipment and valves, further cool the air, separate and remove impurities such as moisture and oil from the compressed air, reduce the workload of other processing equipment downstream of the pipeline network, and ensure that various gas-consuming equipment obtain the required quality gas source.

[0003] High-pressure gas tanks use filters when storing gas. The filters will become clogged after working for a long time. If the filters are not cleaned in time, the gas storage resistance will increase, and the filter may even lose its filtering function and pollute the entire gas tank.

[0004] When a high-pressure gas tank is exhausted, part of the internal energy of the compressed gas is converted into kinetic energy, causing the temperature at the outlet to drop. As a result, liquid droplets often form on the outside of the gas tank outlet, and even frost may form. The faster the high-pressure gas is discharged from the outlet, the greater the temperature drop, which leads to severe frost formation at the outlet. This phenomenon not only affects the normal use of the gas tank, but may also cause fatigue failure of the weld connecting the exhaust pipe and the shell due to temperature differential stress. Currently, heating is used at the exhaust port to avoid the occurrence of large amounts of liquid droplets or frost, but this heating measure is relatively energy-consuming.

[0005] The outlet of the high-pressure gas tank will produce a lot of noise due to the large pressure difference and high-pressure gas speed.

[0006] The present invention designs a high-pressure gas tank to solve the above problems. Summary of the Invention

[0007] Based on this, it is necessary to provide a high-pressure gas tank to address the problems existing in the current high-pressure gas tank. In the present invention, the second gas cylinder of the air filter assembly is separated from the third gas cylinder when the first valve plug is closed to the ring plate, and the clean high-pressure air in the main gas tank is reversely passed through the air filter and the impurities attached to the outside of the air filter are blown out from the gap between the second gas cylinder and the third gas cylinder. There is no need to replace the air filter, and the clean high-pressure air in the main gas tank is used for reverse self-cleaning. The cleaning efficiency of the air filter is high and the cleaning cost of the air filter is low. The air filter is prevented from being blocked due to long-term operation, resulting in the failure of the filtering function, and ensuring that the air filter assembly continuously inputs clean high-pressure air into the main gas tank. The pressure regulating assembly in the present invention effectively reduces the pressure difference at the air inlet of the transition gas tank by utilizing its own rotary vane air pump structure and effectively adjusts the pressure difference at the air inlet of the transition gas tank according to specific needs, thereby realizing the conversion of the kinetic energy of the high-pressure air coming out of the main gas tank into internal energy, and then relatively warming the air at the air inlet of the transition gas tank to a certain extent, thereby eliminating or weakening the frost at the air inlet of the transition gas tank. The pressure regulating assembly of the present invention reduces the pressure of the high-pressure air from the main gas tank at the air inlet of the transition gas tank and effectively reduces the air velocity at the air inlet of the transition gas tank, thereby eliminating or reducing the noise caused by the large pressure difference at the air inlet of the transition gas tank. The pressure regulating assembly of the present invention is intermittently used by the main gas tank to inflate the transition gas tank. During the process of the pressure regulating assembly transferring the high-pressure air from the main gas tank to the transition gas tank, the high-pressure air transferred by the pressure regulating assembly can fully exchange heat with the outside air during the transmission process and be heated to a certain extent, further increasing the air temperature at the air inlet of the transition gas tank and further reducing frost at the air inlet of the transition gas tank. No additional heating structure is required, effectively reducing energy consumption.

[0039] In a further embodiment, Figure 7 、 Figure 10 As shown, the driving assembly 438 includes a first motor 451 and a second motor 454 arranged on the outside of the cylindrical shell 401 through a fifth bracket 439, and the second rotating shaft 442, the third rotating shaft 445, the fourth rotating shaft 453 connected to the second motor 454, the fifth rotating shaft 457 and the sixth rotating shaft 460 connected to the first motor 451 are rotatably arranged on the fifth bracket 439, the third rotating shaft 445 and the fourth rotating shaft 453 are coaxially distributed, and the two ends of the fifth rotating shaft 457 are provided with an eleventh gear 456 and a twelfth gear 458, the eleventh gear 456 is engaged with the tenth gear 455 on the fourth rotating shaft 453, the twelfth gear 458 is engaged with the thirteenth gear 459 on the first rotating shaft 432, and the second rotating shaft 44 2 are provided with a third gear 441 and a fourth gear 443 at both ends of the vehicle body. The third gear 441 is engaged with the second gear 440 on the first shaft sleeve 429, and the fourth gear 443 is engaged with the fifth gear 444 on the third rotating shaft 445. A second shaft sleeve 452 is rotatably provided on the fourth rotating shaft 453, and an eighth gear 449 is provided on the second shaft sleeve 452. The eighth gear 449 is engaged with the ninth gear 450 on the sixth rotating shaft 460. Two fixed seats 448 are symmetrically provided on the end surface of the eighth gear 449, and a seventh gear 447 is provided on the fixed seat 448. Sixth gears 446 are provided on both the third rotating shaft 445 and the fourth rotating shaft 453. The two sixth gears 446 are simultaneously engaged with the two seventh gears 447.

[0040] In a further embodiment, Figure 10As shown, the transmission ratio of the tenth gear 455 to the eleventh gear 456 is equal to the transmission ratio of the fifth gear 444 to the fourth gear 443, and the transmission ratio of the twelfth gear 458 to the thirteenth gear 459 is equal to the transmission ratio of the third gear 441 to the second gear 440, ensuring that the second motor 454 can drive the first rotor 430 and the third rotor 436 to rotate synchronously and at the same speed when the first motor 451 with a self-locking function is not running.

[0041] The operation process of the present invention is as follows: In the initial state, such as Figure 17 As described in (a), the first rotor 430 is located on the left side of the first air channel 415 and is extremely close to the first air channel 415. The slider 420 closes the first air channel 415 and the second air channel 416 and opens the third air channel 417. The first solenoid valve 203, the second solenoid valve 321, the third solenoid valve 404, and the fourth solenoid valve 419 are in the closed state. The second valve plug 411 of the valve assembly 407 closes the suction and discharge port 406 at the end of the fourth air pipe 405 under the action of the first spring 412. Figure 3 As described above, the first valve plug 317 opens the air hole in the middle of the ring plate 306, and the second air cylinder 305 and the third air cylinder 319 are in a sealed docking state.

[0042] When it is necessary to inflate high-pressure air into the main air tank 101 through the air filter assembly 300 by the booster air pump 104, start the booster air pump 104 and open the second solenoid valve 321. The booster air pump 104 pressurizes the air and allows the high-pressure air to be stored in the main air tank 101 through the first air pipe 301, the first air cylinder 302, the telescopic cylinder 304, the second air cylinder 305, the third air cylinder 319 and the second air pipe 320. When enough high-pressure air is stored in the main air tank 101 and reaches a certain air pressure value, stop the booster air pump 104 and close the second solenoid valve 321.

[0043] After the air filter assembly 300 has been used for a period of time, a large amount of impurities accumulate on the second air cylinder 305 side of the air filter 323, causing it to become clogged. At this time, the first electric push rod 314 is activated. The first electric push rod 314 drives the first valve plug 317 through the second guide rod 313 to close the air holes on the ring plate 306. At the same time, the second guide rod 313 drives the second air cylinder 305 to separate from the third air cylinder 319 through the second rack 316, the first gear 318 and the first rack 310, so that the second air cylinder 305 side of the third air cylinder 319 is opened. Then, the second solenoid valve 321 is opened, and the clean high-pressure air in the main air tank 101 is discharged through the second air pipe 320 in the opposite direction through the air filter 323 and the third air cylinder 319. During the process of the high-pressure air in the main air tank 101 reversely entering the air filter 323, the high-pressure air blows away the impurities attached to the outer cone surface of the air filter 323 and expel them out of the third air cylinder 319, thereby completing the reverse self-cleaning of the air filter 323.

[0044] After the air filter 323 is cleaned, the second solenoid valve 321 is closed. Then, the first electric push rod 314 is started to drive the first valve plug 317 to open the air hole in the middle of the ring plate 306. At the same time, the second guide rod 313 on the first valve plug 317 drives the second air cylinder 305 to re-sealed with the third air cylinder 319 through a series of transmissions.

[0045] After the main gas tank 101 has been used for a period of time, the switch valve 103 on the bottom drain pipe 102 is opened, and the water accumulated at the bottom of the main gas tank 101 is discharged under the push of the high-pressure air therein. After the water in the main gas tank 101 is completely drained, the switch valve 103 can be closed.

[0046] When it is necessary to deliver the high-pressure air in the main gas tank 101 to the bottle blowing equipment, the angle between the first rotor 430 and the third rotor 436 is first adjusted according to the required air pressure in the transition gas tank 201 and the required pressure difference at the air inlet of the transition gas tank 201. The specific adjustment process is as follows: The first motor 451 is started and drives the two seventh gears 447 to rotate about the fourth rotating shaft 453 and relative to the fourth rotating shaft 453 by a certain angle via the sixth rotating shaft 460, the ninth gear 450, the eighth gear 449, and the fixing base 448. Since the second motor 454 has a self-locking function, the two seventh gears 447 rotate under the action of the sixth gear 446 on the fourth rotating shaft 453. The two seventh gears 447 drive the sector block 425 to rotate by a certain angle relative to the second rotating vane 433 and the third rotating vane 436 via the sixth gear 446 on the third rotating shaft 445, the third rotating shaft 445, the fifth gear 444, the fourth gear 443, the second rotating shaft 442, the third gear 441, the second gear 440, and the first shaft sleeve 429, thereby completing the adjustment of the angle between the first rotating vane 430 and the third rotating vane 436. During adjustment of the angle between the first rotor 430 and the third rotor 436, the second electric push rod 423 drives the slider 420 to move a certain range, causing the slider 420 to open the first air channel 415 and the second air channel 416 and close the third air channel 417, thereby connecting the first air channel 415 with the second air channel 416 through the air cavity 414. Simultaneously, a thin rod pushes the second valve plug 411 through the suction and discharge port 406 on the fourth air pipe 405, thereby connecting the sealed space on the side of the third rotor 436 in the cylindrical shell 401 to the outside world, and the first spring 412 is further compressed to store energy. This ensures that air is transferred or replenished between the two sealed spaces between the first and third rotors 430, 436 and the top tangent of the cylindrical shell 401, thereby preventing the two sealed spaces from being blocked and unable to adjust the angle between the first and third rotors 430, 436 during the change of the angle between the first and third rotors 430, 436. During the process of adjusting the angle between the first rotor 430 and the third rotor 436, the second motor 454 is simultaneously started. The second motor 454 drives the first rotor 430 and the third rotor 436 to rotate synchronously through a series of transmissions, thereby creating a speed difference between the first rotor 430 and the third rotor 436. This maintains the first rotor 430 in its initial position, while causing the third rotor 436 to rotate relative to the first rotor 430 and the cylindrical shell 401, thereby completing the adjustment of the angle between the first rotor 430 and the third rotor 436.

[0047] After the angle adjustment between the first rotor 430 and the third rotor 436 is completed, the second valve plug 411 is removed so that the second valve plug 411 closes the suction and discharge port 406 of the fourth air pipe 405 .

[0048] After the angle between the first rotary vane 430 and the third rotary vane 436 is adjusted, the second electric push rod 423 is activated to drive the slider 420 to slide back to close the first air channel 415 and the second air channel 416 and open the third air channel 417.

[0049] Then, if Figure 17 As shown in (b), the third solenoid valve 404 is opened for a period of time, and the high-pressure gas in the main gas tank 101 enters the sealed space between the first rotor 430 and the top tangent of the cylindrical shell 401 through the third gas pipe 403 and drives the first rotor 430 to rotate. At the same time, the second motor 454 is started to drive the fourth shaft 453 to adaptively rotate the third shaft 445 without hindrance. The fourth shaft 453 drives the third rotor 436 to rotate synchronously with the first rotor 430 at the same speed through a series of transmissions. The third rotor 436 compresses the air in the sealed space between it and the top tangent of the cylindrical shell 401. When the air in the sealed space between the first rotor 430 and the top tangent of the cylindrical shell 401 reaches the required amount, the third solenoid valve 404 is closed, and the main gas tank 101 is used to press the third solenoid valve 404 to release the compressed air. The pressure of the high-pressure air entering the sealed space between the first rotor 430 and the top tangent of the cylindrical shell 401 gradually decreases, while the air in the sealed space between the third rotor 436 and the top tangent of the cylindrical shell 401 is compressed and the pressure gradually increases. When the pressures in the two spaces reach equilibrium, the rotation of the first rotor 430 and the third rotor 436 stops. The larger the angle between the first rotor 430 and the third rotor 436, the smaller the volume of air in the sealed space between the third rotor 436 and the top tangent of the cylindrical shell 401, and the greater the final equilibrium pressure in the two sealed spaces. The final equilibrium pressure in the two sealed spaces depends on the pressure value in the transition gas tank 201, ensuring that the pressure difference at the air inlet of the transition gas tank 201 is maintained within a stable value range.

[0050] like Figure 17 As shown in (c), when the air pressure in the two sealed spaces reaches equilibrium, the second electric push rod 423 is started to drive the slider 420 to move a certain amplitude, so that the vent hole 421 on the slider 420 is opposite to the second air channel 416 and the slider 420 does not close the third air channel 417, thereby making the first air channel 415 and the second air channel 416 connected to the air cavity 414 at the same time. The air in the two sealed spaces with an air pressure lower than that in the main air tank 101 enters the third air channel 417 through the first air channel 415 and the second air channel 416, and the fourth solenoid valve 419 is opened. The lower-pressure air entering the third air channel 417 enters the transition air tank 201 for temporary storage.

[0051] When the air pressure in the two sealed spaces on both sides of the top tangent line of the cylindrical shell 401 reaches equilibrium with the air pressure in the transition gas tank 201, Figure 17As shown in (d), the second electric push rod 423 is started to drive the slider 420 to continue moving, so that the slider 420 closes the third air channel 417 and still keeps the first air channel 415 open. The air vent 421 on the slider 420 is connected to the second air channel 416 and the air cavity 414, and the first air channel 415 is still connected to the second air channel 416 through the air cavity 414. At this time, the second motor 454 is started to run in the reverse direction and drive the first rotor 430 and the third rotor 436 to rotate in the reverse direction to restore the initial state. The air in the two sealed spaces is connected through the first air channel 415, the air cavity 414 and the second air channel 416 without suffocation.

[0052] After the first rotary vane 430 and the third rotary vane 436 rotate and reset, the fourth solenoid valve 419 is closed to block the communication between the air cavity 414 and the transition gas tank 201, and the second electric push rod 423 is started to drive the slider 420 to slide back and reset.

[0053] In this way, the above process is repeated to inflate the intermediate gas tank 201 from the main gas tank 101. When the pressure in the intermediate gas tank 201 reaches the desired value, the main gas tank 101 stops inflating the intermediate gas tank 201, and the third solenoid valve 404 and the fourth solenoid valve 419 are closed. The first solenoid valve 203 is opened, allowing the high-pressure air in the intermediate gas tank 201 to be delivered to the bottle blowing equipment through the exhaust pipe 202 for bottle blowing.

[0054] The final equilibrium pressure in the two sealed spaces on either side of the top tangent line of the cylindrical shell 401 ensures that there is no or minimal noise at the inlet of the transitional gas tank 201 during inflation. The final equilibrium pressure in the two sealed spaces is much lower than the pressure in the main gas tank 101, so that the air in the two sealed spaces simultaneously moves into the transitional gas tank 201 at a lower speed, preventing frost from forming at the inlet of the transitional gas tank 201.
