摘要

Usage: for biological wastewater treatment. SUMMARY OF THE INVENTION: A device for forcing air to the aerator rotor comprises a hollow shaft with air inlet openings in the upper part. The lower end of the shaft is connected to the rotor of the aerator, and the upper end is connected to the shaft of the electric motor. The electric motor is located on the support flange inside the ventilation casing. The hollow shaft guide tube is fixed with its upper end in the hole of the support flange. On the hollow shaft, on both sides of the air inlets of the upper and lower impellers of the axial fan, the guide tube is provided with an air duct connected to it below the lower impeller in the support pipe and to the ventilation casing of the electric motor. The hollow shaft above its air intake holes is muffled. 1 ill. (L C
