AI Technical Summary

Technical Problem

The expansion and buckling of the mill's electrical circuit under high temperature conditions can cause unstable power supply to the coal loading car, potentially breaking the pressure plate screws, causing grounding or short circuits, and affecting the normal operation of the coal loading car.

Method used

An air duct is installed below the grinding circuit. Inside the air duct are blowers and baffles. Airflow blows through the air outlet onto the grinding circuit. Combined with dumbbell-shaped air columns for shock absorption, this ensures even airflow distribution and prevents heat buildup in the grinding circuit.

Benefits of technology

Effective heat dissipation prevents the mill's electrical track from expanding and buckling, ensuring normal power supply operation of the coal loading car. It is suitable for long mill electrical tracks, ensuring uniform heat dissipation throughout and improving power supply stability.

An air duct 3 is provided on the supporting porcelain insulator 2. The air duct 3 extends in an S-shape and wraps around the supporting porcelain insulator 2. Blowers 4 are connected to both ends of the air duct 3. The two blowers 4 blow air into the air duct 3 from both ends of the air duct 3. The air duct 3 also has a section along its length that is equal to the length of the air duct 3. The long partition 5 divides the inner cavity of the air duct 3 into a basic flow channel 6 and a pressure-holding flow channel 7. Multiple first air outlets 8 connected to the basic flow channel 6 and multiple second air outlets 9 connected to the pressure-holding flow channel 7 are provided on the outer top surface of the air duct 3. The first air outlets 8 and the second air outlets 9 are staggered. This can prevent the air outlets near the blower 4 from being too dense and thus affecting the air pressure of the air outlet at the far end of the blower 4. Through the cooperation of the basic flow channel 6 and the pressure-holding flow channel 7, the number of air outlets is reduced by half at the same distance, which helps to ensure the air pressure of the air outlet at the far end of the blower 4.
