[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. The utility model provides a cooling mechanism. First, the water in the inner cavity of the cold water tank is cooled by a refrigeration pipe, and then the cold water is pumped into the inner cavity of the water distribution tank by a water pump. Then, the cold water in the inner cavity of the water distribution tank is injected into the water storage pipe through the water injection pipe, and then the connecting shaft is driven to rotate by the output end of the servo motor. At this time, the connecting shaft drives the driving gear to rotate synchronously. Due to the rotation of the driving gear, the driven gear meshing with the driving gear rotates synchronously, and the driven gear and the driving gear are rotated to drive the connecting rod, the stirring blade, the water storage pipe and the high-pressure nozzle to rotate. The cracked gas in the inner cavity of the cooling box is stirred to flow by the rotation of the stirring blade, the water storage pipe and the high-pressure nozzle rotate, and cold water is sprayed by the high-pressure nozzle to spray and cool the cracked gas in the inner cavity of the cooling box, and then the gas is returned to the inner cavity of the cold water tank again through the return pipe to complete the cooling of the cracked gas. By quickly cooling the cracked gas, the cooling time can be greatly reduced compared with natural cooling, thereby effectively improving the overall processing speed of the cracked gas.

[0017] Second, the utility model can support the water injection pipe by arranging the card plate and the support rod, so as to prevent the water injection pipe from falling off after long-term use, thereby causing the problem that cold water cannot be transported to the inner cavity of the cooling box. By arranging the temperature sensing probe and the temperature display panel, the temperature in the inner cavity of the cooling box can be conveniently detected in real time, so as to understand the real-time temperature of the cracked gas in the inner cavity of the cooling box. By arranging the return pipe, the cold water in the inner cavity of the cooling box can be conveniently recycled and reused, thus saving water consumption and allowing the cold water to be used multiple times. By arranging the slide groove and the slider, The rotation of the driving gear can be conveniently limited to avoid the deviation of the driving gear after long-term use, thereby affecting the cooling effect of the cracking gas. By setting the flange, the air inlet pipe can be conveniently extended to facilitate the transportation of the cracking gas. By setting the one-way air outlet valve, the cracking gas in the inner cavity of the cooling box can be sealed to avoid the leakage of the cracking gas from the exhaust pipe when the temperature is not lowered to the required temperature. By setting the anchor bolts, the whole equipment can be stabilized to avoid the equipment from tipping over due to unexpected external collisions.
