Like this, the air shock wave jetting system of this embodiment is through setting up reposition of redundant personnel structure 2 in gas holder 1, and with reposition of redundant personnel structure 2 and the 11 intercommunications of first air inlet of gas holder 1, when making the compressed air that the air supply provided fills gas holder 1 by the first air inlet 11 of gas holder 1, compressed air is via reposition of redundant personnel structure 2 reposition of redundant personnel, partly compressed air directly fills in gas holder 1, in another part compressed air fills cylinder subassembly 3, the inflation time has been shortened effectively, the inflation efficiency of gas holder 1 has been improved, moreover, the steam generator is simple in structure, easy processing.

Specifically, since the air storage tank 1 is generally fixed to the wall of the boiler in a vertical state, the first air outlet 12 of the air storage tank 1 is disposed at the bottom of the air storage tank 1, so that the compressed air in the air storage tank 1 can be smoothly discharged from the bottom of the air storage tank 1 by gravity.

Further, as shown in fig. 1, a lifting lug 14 is further disposed on the gas storage tank 1, and the lifting lug 14 is welded to the top of the gas storage tank 1. Thus, the gas storage tank 1 can be lifted by using a rope at the lifting lug 14, so that the gas storage tank 1 can be conveniently carried, disassembled and assembled.

Further, as shown in fig. 1, a tank bracket 15 is further disposed on the air storage tank 1, and the tank bracket 15 is welded to a side surface of the air storage tank 1. In this way, the tank bracket 15 is fixed to the boiler wall of the boiler to fix the gas storage tank 1.

Optionally, as shown in fig. 2, the flow dividing structure 2 is a three-way joint, and the three-way joint has a first air port 21, a second air port 22 and a third air port 23; the first port 21 constitutes a fifth inlet port, and the second port 22 and the third port 23 constitute a second outlet port.

In the embodiment, the flow dividing structure 2 is preferably a three-way joint, so that the compressed air entering from the first air inlet 11 of the air storage tank 1 is divided at the three-way joint, and the charged compressed air is respectively charged into the air storage tank 1 and the cylinder assembly 3 through the second air port 22 and the third air port 23 of the three-way joint, so that the structure is simple, the cost is low, and the flow dividing effect is realized while the reconstruction cost is not excessively increased.

Alternatively, as shown in fig. 3, the cylinder assembly 3 includes a cylinder block bracket 31, a cylinder 32 fixed on the cylinder block bracket 31, a piston 33, a push rod 34, and an exhaust cover 35; the third air inlet 321 is arranged on the air cylinder 32, one end of the push rod 34 is arranged in the air cylinder 32 and connected with the piston 33, and the other end of the push rod 34 extends out of the air cylinder 32 and is connected with the exhaust cover 35; and the piston 33 is adapted to slide along the inner wall of the cylinder 32 under pressure to urge the exhaust cover 35 to block or communicate the first air outlet 12.

In this embodiment, the cylinder 32 is also vertically disposed, so that the piston 33 disposed in the cylinder 32 can move up and down in the cylinder 32, the upper end of the push rod 34 extends into the cylinder 32 and is fixedly connected with the piston 33, the lower end of the push rod 34 extends out of the cylinder 32, and the exhaust cover 35 is located outside the cylinder 32 and is fixed at the lower end of the push rod 34. When the air storage tank 1 is inflated and exhausted, the pressures on the upper side and the lower side of the piston 33 are different, and when the air storage tank 1 is inflated, the pressure on the upper side of the piston 33 is larger than the pressure on the lower side of the piston, so that the piston 33 moves downwards and drives the exhaust cover 35 on the push rod 34 to move downwards until the first air outlet 12 of the air storage tank 1 is blocked; when the air storage tank 1 exhausts, the pressure on the upper side of the piston 33 is smaller than that on the lower side, so that the piston 33 moves upwards, the exhaust cover 35 on the push rod 34 is driven to move upwards, the first air outlet 12 of the air storage tank 1 is communicated, and compressed air in the air storage tank 1 is rapidly discharged from the first air outlet 12.

Like this, when the compressed air that shunts via reposition of redundant personnel structure 2 fills in cylinder 32, can promote piston 33 downstream to drive the exhaust cover 35 downstream on the push rod 34, block up the first gas outlet 12 of gas holder 1 until exhaust cover 35, make gas holder 1 form a enclosed construction, so that aerify gas holder 1, prevent that gas holder 1 from appearing aerifing the phenomenon that produces the gas leakage in first gas outlet 12 department simultaneously, thereby further improve the gas charging efficiency of gas holder 1.

Further, the exhaust cover 35 may be fixedly connected with the lower end of the push rod 34, or may be detachably connected. In this embodiment, it is preferable that the exhaust cover 35 is detachably coupled to the lower end of the push rod 34 from the viewpoint of easy detachment. In one embodiment, the lower end of the push rod 34 is provided with a boss and an external thread, the exhaust cover 35 is sleeved on the lower end of the push rod 34, and the exhaust cover 35 is limited between the boss and the nut by screwing the nut on the lower end of the push rod 34, so that the exhaust cover 35 is fixed on the lower end of the push rod 34.

Optionally, as shown in fig. 3, the air storage tank 1 is further provided with a second air inlet 13, the air cylinder 32 is further provided with a fourth air inlet 322, and the second air inlet 13 is communicated with the fourth air inlet 322; the piston 33 divides the inner space of the cylinder 32 into an upper cavity 323 and a lower cavity 324, and the third intake port 321 communicates with the upper cavity 323 and the fourth intake port 322 communicates with the lower cavity 324.

In this embodiment, when the air storage tank 1 is inflated, compressed air is inflated into the first air inlet 11 of the air storage tank 1, after the compressed air is split by the split-flow structure 2, a part of the compressed air enters the upper cavity 323 of the air cylinder 32 through the third air inlet 31 of the air cylinder 32, so that the pressure of the upper cavity 323 is greater than that of the lower cavity 324, and under the action of the pressure difference between the upper cavity 323 and the lower cavity 324, the piston 33 drives the push rod 34 to move downward until the exhaust cover 35 on the push rod 34 blocks the first air outlet 12 of the air storage tank 1; when the air storage tank 1 is required to exhaust air, when compressed air is firstly charged into the second air inlet 13 of the air storage tank 1, the compressed air only enters the lower cavity 324 of the air cylinder 32 from the fourth air inlet 322 communicated with the second air inlet 13, so that the pressure of the lower cavity 324 is greater than that of the upper cavity 323, the piston 33 is promoted to drive the push rod 34 to move upwards, the exhaust cover 35 on the push rod 34 leaves the first air outlet 12 of the air storage tank 1, the first air outlet 12 of the air storage tank 1 is communicated, and the compressed air in the air storage tank 1 is rapidly discharged from the first air outlet 12. Therefore, the piston 33 drives the exhaust cover 35 to block and conduct the first air outlet 12 of the air storage tank 1 under the action of the pressure difference between the upper cavity 323 and the lower cavity 324.

Further, when the second air port 22 of the three-way joint is used for communicating with the inner cavity of the air storage tank 1, and the third air port 23 of the three-way joint is used for communicating with the upper cavity 323 of the air cylinder 32, a first one-way valve is arranged at the second air port 22, an air inlet of the first one-way valve is communicated with the second air port 22 of the three-way joint, and an air outlet of the first one-way valve is communicated with the inner cavity of the air storage tank 1. Therefore, the compressed air provided by the air source is filled into the air storage tank 1 through the first one-way valve by the second air port 22, and the compressed air in the air storage tank 1 cannot flow back into the three-way joint through the first one-way valve, and cannot flow back into the air cylinder 32 from the third air port 23 of the three-way joint, so that the compressed air in the air storage tank 1 can be prevented from flowing back into the air cylinder 32, and the air filling efficiency of the air storage tank 1 is further improved.

Further, as shown in fig. 1, the air shock wave blowing system further includes a control cabinet, an air supply assembly and a control valve set, the air supply assembly includes an air source and an air supply pipeline connected to the air source, the control valve set includes an electromagnetic valve 7 disposed on the air supply pipeline, a pressure switch 8 disposed on the air storage tank 1 and a safety valve 9, and a first air inlet 11 and a second air inlet 13 of the air storage tank 1 are connected to the electromagnetic valve 7 through pipelines respectively. When the gas storage tank 1 is inflated, the control cabinet control electromagnetic valve 7 conducts the gas supply pipeline and the first gas inlet 11 and disconnects the gas supply pipeline and the second gas inlet 13, and after the inflation is completed, the control cabinet control electromagnetic valve 7 disconnects the gas supply pipeline and the first gas inlet 11 so as to stop supplying gas to the gas storage tank 1; when the air storage tank 1 needs to exhaust air, the control cabinet controls the electromagnetic valve 7 to conduct the air supply pipeline and the second air inlet 13 and disconnect the air supply pipeline and the first air inlet 11, and after the first air outlet 12 of the air storage tank 1 is conducted, the control cabinet controls the electromagnetic valve 7 to disconnect the air supply pipeline and the second air inlet 13 so as to stop supplying air to the air cylinder 32; therefore, the automatic inflation of the air storage tank 1 and the air cylinder 32 and the automatic opening and closing of the first air outlet 12 of the air storage tank 1 can be realized through the electromagnetic valve 7, the operation is simple and convenient, and the automation degree is high.

Optionally, as shown in fig. 3, the cylinder assembly 3 further includes a second check valve 36, an air inlet of the second check valve 36 is communicated with the inner cavity of the air storage tank 1, and an air outlet of the second check valve 36 is communicated with the upper cavity 323 of the cylinder 32.

In this embodiment, the second check valve 36 is disposed generally at the upper end of the cylinder 32, with the inlet of the second check valve 36 facing upward and the outlet of the second check valve 36 facing downward. At the initial stage of charging the air storage tank 1, the pressure in the upper cavity 323 of the air cylinder 32 is not enough to make the second check valve 36 conduct reversely, which makes the compressed air charged into the inner cavity of the air storage tank 1 enter the upper cavity 323 of the air cylinder 32 from the second check valve 36, that is, at the initial stage of charging the air storage tank 1, the compressed air enters the upper cavity 323 from the third air inlet 321 on the upper cavity 323 and the second check valve 36 to increase the pressure of the upper cavity 323 rapidly, so as to cause the piston 33 to move downward rapidly to drive the exhaust cover 35 to block the first air outlet 12 of the air storage tank 1; when the pressure in the upper cavity 323 of the cylinder 32 exceeds the upper limit pressure value of the second check valve 36, the second check valve 36 is reversely conducted, so that the compressed air in the upper cavity 323 of the cylinder 32 can enter the inner cavity of the air storage tank 1 from the second check valve 36. Thus, when the air storage tank 1 is inflated, the pressure of the upper cavity 323 of the air cylinder 32 is always greater than that of the lower cavity 324, so that the exhaust cover 35 can continuously block the first air outlet 12; meanwhile, when the pressure in the air cylinder 32 is too high, the pressure can be relieved through the second one-way valve 36, so that the damage to the air cylinder 32 and parts in the air cylinder 32 caused by the too high pressure in the air cylinder 32 is prevented; moreover, redundant compressed air in the air cylinder 32 can be discharged into the inner cavity of the air storage tank 1, so that the air storage tank 1 is further inflated, and the inflation efficiency is improved.

Further, a second check valve 36 is detachably mounted on the cylinder 32 as a separate component. So, when second check valve 36 takes place to damage, can directly change second check valve 36, and need not to change together with whole cylinder 32, prolonged the life of cylinder 32, simultaneously, cylinder 32 can regard as a general standard component to reduce the cost of whole cylinder assembly 3, practice thrift the cost.

Further, the vertical distance between the third air inlet 321 and the fourth air inlet 322 is larger than the stroke when the piston 33 vertically moves. That is, the piston 33 reciprocates only between the third intake port 321 and the fourth intake port 322. In order to increase the stroke of the piston 33 when moving vertically, the third air inlet 321 is usually disposed near the upper end of the cylinder 32, and the fourth air inlet 322 is disposed near the lower end of the cylinder 32, so that when the piston 33 drives the exhaust cover 35 to move downward to block the first air outlet 12, the piston 33 does not block the fourth air inlet 322, and when the piston 33 drives the exhaust cover 35 to move upward to separate the exhaust cover 35 from the first air outlet 12 and move upward to a certain height, the piston 33 does not block the third air inlet 321; thus, the obstruction of the third air inlet 321 and the fourth air inlet 322 by the piston 33 during air intake can be avoided, and the smoothness of air intake of the upper cavity 323 or the lower cavity 324 of the cylinder 32 can be ensured.

Optionally, as shown in fig. 3, the cylinder assembly 3 further includes a diversion cover 37, and the diversion cover 37 is disposed at an end of the push rod 34 away from the piston 33 and on a side of the exhaust cover 35 away from the cylinder 32.

In this embodiment, the downward end of the diversion cover 37 is in the shape of an inverted cone, so that when the diversion cover 37 discharges compressed air in the air storage tank 1 downward, the inverted cone surface on the diversion cover 37 can guide airflow to discharge out of the air storage tank 1 quickly, and the exhaust effect can be improved; also, the airflow is less likely to swirl at the guide cover 37 when passing through the guide cover 37, thereby reducing noise when exhausting. In addition, in the prior art, the exhaust cover 35 is usually inserted into a connecting pipe communicated with the first air outlet 12 of the air tank 1 to seal the first air outlet 12 of the air tank 1, but the sealing method is easy to generate high failure rate due to poor sealing. In the embodiment, the diversion cover 37 is arranged, and the inverted cone on the diversion cover 37 is used for sealing the first air outlet 12 of the air storage tank 1, so that the processing is easy, the contact area between the diversion cover 37 and the inner wall of the connecting pipe at the first air outlet 12 is increased, namely, the sealing area is increased, the sealing effect is better, and the failure rate of the air storage tank 1 during inflation is reduced.

Optionally, as shown in fig. 3, the cylinder assembly 3 further includes a first sealing element 38 disposed between the exhaust cover 35 and the flow guide cover 37, and the exhaust cover 35 and the flow guide cover 37 are hermetically connected by the first sealing element 38.

When there is a gap between the discharge cover 35 and the deflector cover 37, the air flow may enter the gap during the discharge of the gas container 1, and generate vortex and noise, which may affect the discharge effect. In the present embodiment, the first sealing member 38 is disposed between the diversion cover 37 and the exhaust cover 35 to ensure the sealing performance when the diversion cover 37 is connected with the exhaust cover 35, so as to prevent the airflow from entering between the diversion cover 37 and the exhaust cover 35.

Specifically, the nozzle 5 is inserted in the blowing pipe 4 and can rotate on the blowing pipe 4, the insertion between the nozzle 5 and the blowing pipe 4 can be realized by arranging a spigot structure on both the nozzle 5 and the blowing pipe 4, and the spigot structure is used for forming insertion, or the inner diameter of the nozzle 5 is set to be slightly larger than the outer diameter of the blowing pipe 4, so that the nozzle 5 can be inserted on the blowing pipe 4 in a sleeved mode.

Furthermore, one end of the injection pipe 4 connected with the air storage tank 1 extends into the air storage tank 1 from the first air outlet 12 and is fixedly connected with the air storage tank 1. In the embodiment, one end of the injection pipe 4 extending into the gas storage tank 1 is welded at the first gas outlet 12 of the gas storage tank 1, so that the firmness of connection between the injection pipe 4 and the gas storage tank 1 is improved; in addition, a part of the upper end of the blowing pipe 4 extends into the air storage tank 1, so that the firmness of the joint of the blowing pipe 4 and the air storage tank 1 can be enhanced, and when the blowing pipe 4 is impacted in the horizontal direction, the joint of the blowing pipe 4 and the air storage tank 1 is not easy to break.

Alternatively, as shown in fig. 1, the driving mechanism 6 includes a driving assembly and a rotating shaft 62, one end of the rotating shaft 62 is connected to the driving assembly, and the other end of the rotating shaft 62 extends into the blowing pipe 4 and is connected to the nozzle 5 to drive the nozzle 5 to rotate.
