Description
A high-pressure fumigation gas diffusion device Technical Field
[0001] This utility model relates to the field of high-pressure fumigation gas diffusion technology, and more specifically to a high-pressure fumigation gas diffusion device. Background Technology
[0002] High-pressure fumigation gas diffusion devices are mainly used for fumigation operations in specific environments. Under high pressure, they can evenly and rapidly diffuse fumigation gas into the target space, effectively covering every corner and ensuring comprehensive fumigation treatment of goods and items. This provides insecticidal, sterilizing, and mildew-proofing effects, ensuring the quality and storage safety of the goods.

[0027] The working principle of this utility model:
[0028] The device is placed horizontally above the ground. The operator injects fumigation steam into the pressurization chamber 401 through the air inlet 402. The pressurization pump 503 then begins pressurizing the chamber. During this process, the pressure detector 405 monitors the internal pressure of the chamber in real time. After opening the cover assembly 3, the operator hangs the material to be sprayed on the hanging plate 303 and then places it on top of the outer casing 201. The sealing ring 304 effectively prevents fumigation steam from overflowing during operation. After pressurization is complete, the operator rotates the valve 407 to allow the fumigation steam inside the pressurization chamber 401 to enter the outer casing 201 through the delivery pipe 406. The pressurized fumigation steam then... The spray is emitted from the mist spray head 203 and sprayed onto the material. If the pressure detector 405 detects that the internal pressure of the device is too high, it defines this signal as a high-pressure signal and sends it to the controller 504. After receiving the signal, the controller 504 controls the pressure regulating pump 204 to start working. The pressure regulating pump 204 reduces the pressure inside the device, so that the internal pressure of the device is within the preset standard pressure range during operation, thereby improving the working efficiency of the device. The temperature sensor 106 monitors the internal temperature of the device. If the temperature is too high or too low, it defines this signal as an over-limit signal and sends the signal to the controller 504. After receiving the signal, the controller 504 controls the condenser 102 and the heating tube 104 to work together, so that the internal temperature of the device is within the preset standard temperature.
