Hello
Normally my partner and I make Robotic automation cells and mechanics, but we got this additional inquiry of making an air blower cooling tunnel.
So, due to no floor space, I´m investigating the possibilities of making a vertical air-cooling tunnel, floor space approx 1x1m. The tunnel shall cool down zinc die casted items of various sizes and shapes. The items are conveyed through the tunnel in a vertical oriented oval-shaped track. The robot picks and places the items at the same entry hole.
Known input: Cool down time 6 minutes, Capacity 27 kg zinc/6 minutes, weight per item varies up to 1.5 kg, T1=approx 300 C, T2= approx 30 C, ambient temp approx 21 C
I calculated the amount of energy to be removed according to: Q=Cp X (T1-T2) X m
This makes: Q=0,38X27X270=2872,8 KJ to be removed in 6 minutes gives 2872,8KJ/360sek=7980Watt
Is this way out?
Questions:
1) How do I calculate/estimate the air blower capacity?
2) Guidelines for placing the blower unit(s)
3) Anyone who happens to know if it´s possible to buy such a “standard” solution, I haven’t been able to find one myself
