The insertion tube 4 passes through the second connecting piece 102. Under the action of high-flow nitrogen, the pure water inside the second cavity 104 enters the nozzle 3 through the insertion tube 4 and is torn into small droplets by the high-speed nitrogen.

[0040] Working principle:
[0041] In the utility model, the hand valve 13 of the drainage pipe 12 is first closed, and the pneumatic valve 15 of the pure water pipe 14 is opened through the PLC control system, and the pure water enters the second cavity 104 through the fifth through hole 11 of the base 105. When the height of the pure water in the second cavity 104 exceeds the set height of the float type liquid level sensor 5, the float type liquid level sensor 5 transmits a signal to the PLC control system. At this time, the PLC control system controls the pneumatic valve 15 to close, and nitrogen enters from the nitrogen inlet 9. According to the Bernoulli principle, the greater the flow rate of the fluid, the smaller the pressure. Inside the nozzle 3, the pure water in the insertion tube 4 flows toward the high-speed flowing nitrogen, and the pure water is The nitrogen is torn into small droplets, which are sprayed out from the nozzle 3 to form a mist. At this time, the mist-like wet nitrogen in the first cavity 103 is discharged from the wet nitrogen outlet 2. When the pure water level in the second cavity 104 drops, the float-type liquid level sensor 5 again sends a signal to the PLC control system. The PLC control system controls the pneumatic valve 15 to open to replenish the pure water in the second cavity 102. When the water level is too high, the pure water flows out from the overflow port 8 to prevent the pure water from entering the upper cavity and affecting the effect of nitrogen humidification. When the humidification work is completed, the manual valve 13 of the drainage pipe 12 is opened to discharge the pure water that has not been consumed by the device for subsequent disassembly and maintenance.
[0042] The utility model adopts a method of spraying mist-like wet nitrogen through a nozzle, replacing the traditional method of passing nitrogen through a diffusion plate, greatly improving the humidification effect of nitrogen, thereby ensuring the quality of the grinding liquid.
