AI Technical Summary
Traditional grain storage fumigation methods result in uneven distribution of fumigation agents in the grain pile, making it impossible to achieve precise control and directional delivery, which affects the fumigation effect. In addition, the resource utilization efficiency of linear multi-point temperature sensors is low.
The fumigation gas flow delivery pipe fittings are paired and set up in parallel with linear multi-point temperature sensors to form a grain warehouse fumigation pipeline. The precise directional delivery and temperature monitoring of the fumigation gas are achieved through the cable shell and the fumigation gas flow delivery pipe joints. The area control is carried out in combination with the group control valve.
It achieves uniform distribution of fumigation agents in grain piles, improves fumigation effect, saves agent dosage and treatment frequency, reduces storage costs, and makes full use of the layout advantages of temperature sensors.
