An exhaust pipe 17 is fixedly connected to the left side of the exhaust valve 2, a heat dissipation component is installed at the top of the exhaust pipe 17, and the heat dissipation component is used to quickly dissipate the heat of the discharged gas to avoid scalding the staff. The outside of the piston 5 is slidably connected to the inner wall of the exhaust valve 2, and the outside of the spring 4 is sleeved inside the exhaust valve 2.
[0031] Specifically, the main body 1 is the main body of the reactor. The exhaust valve 2 is used to automatically discharge high-pressure gas and connect other parts at the same time. The support plate 3 is used to connect and support the spring 4 and the rotating rod 7. The spring 4 is used to firmly press the piston 5 against the gasket 6. Many holes are provided at the edge of the piston 5 for exhausting gas. Normally, when it presses against the gasket 6, it will always maintain a seal. The gasket 6 is used to maintain the seal and prevent air leakage at low pressure. The exhaust pipe 17 is used to eject gas.
[0032] Referring to Figure 1 - Figure 3 , the heat dissipation component includes a rotating rod 7 and a water tank 12. The bottom end of the rotating rod 7 is rotatably connected to the top of the support plate 3. A plurality of blades 8 are fixedly connected to the outside of the rotating rod 7. The top of the rotating rod 7 is fixedly connected to a turntable 9. A sliding frame 10 is slidably connected to the top of the turntable 9. A push rod 11 is fixedly connected to the left side of the sliding frame 10. The left end of the push rod 11 is fixedly connected to a sliding plate 13. The outside of the sliding plate 13 is slidably connected to a housing 14. A cooling pipe 15 is fixedly connected to the front side of the housing 14. A water inlet pipe 16 is fixedly connected to the left side of the housing 14. The right side of the water tank 12 is fixedly connected to the bottom left side of the main body 1. The outside of the rotating rod 7 is rotatably connected to the inside of the exhaust valve 2. The outside of the push rod 11 is slidably connected to the inside of the right side of the housing 14. The bottom of the housing 14 is fixedly connected to the top of the exhaust pipe 17. The outside of the water inlet pipe 16 is sleeved inside the exhaust pipe 17. The inside of the cooling pipe 15 is fixedly connected to the outside of the exhaust pipe 17. The outside of the water inlet pipe 16 is sleeved inside the inside of the cooling pipe 15. The bottom of the cooling pipe 15 is sleeved inside the water tank 12. The bottom of the water inlet pipe 16 is arranged inside the water tank 12.
[0033] Specifically, the rotating rod 7 is used to drive the turntable 9 to rotate. The blades 8 are driven to rotate by the exhausted gas. The turntable 9 is used to drive the sliding frame 10 to move back and forth left and right. The sliding frame 10 is used to drive the push rod 11 to move synchronously. The push rod 11 is used to reciprocate the sliding plate 13. The housing 14 and the sliding plate 13 cooperate to suck and discharge water. The cooling pipe 15 is wound around the exhaust pipe 17 to conduct the temperature to the exhaust pipe 17 and cool the gas passing through its inside. The water inlet pipe 16 passes through the middle of the exhaust pipe 17. In addition to transporting water, it can also cool the gas in the middle of the exhaust pipe 17. One-way valves are installed at one end of the cooling pipe 15 and the water inlet pipe 16 close to the housing 14. The one-way valve on the cooling pipe 15 only discharges and does not intake. The one-way valve on the water inlet pipe 16 only intakes and does not discharge. The water tank 12 is used to store water and collect the condensed water dripping from the exhaust pipe 17 at the same time.
[0034] Working principle: When using this device, due to the mutual reaction of materials, some gases will be generated. In combination with high temperature, a high-pressure environment is easily generated inside the main body 1. When the pressure reaches a certain value, the pressure will push the piston 5 to compress, disconnect from the gasket 6, and the gas will run upward through the holes around the piston 5 and finally be discharged from the exhaust pipe 17. During the discharge process, the gas drives the blade 8 to operate, drives the rotating rod 7 to rotate, makes the turntable 9 drive the sliding frame 10 to move back and forth left and right, drives the push rod 11 to make the sliding plate 13 move synchronously, and continuously slides inside the outer shell 14. Under the action of two one-way valves, when the sliding plate 13 moves to the right, the water inlet pipe 16 will draw water from the water tank 12 into the outer shell 14. Then the sliding plate 13 moves to the left and flows the water back into the water tank 12 along the cooling pipe 15. During the process of the water flowing in the cooling pipe 15, the temperature is conducted to the exhaust pipe 17, cooling the gas flowing inside the exhaust pipe 17, so that the temperature will not be very high when it is discharged later, avoiding high-temperature burns to workers.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
