application

The BZS2 series rotary brush aerator is used in the oxidation ditch of sewage treatment plants. Its function is to oxygenate the sewage, promote the circulation of sewage in the ditch, and prevent the sedimentation of activated sludge, so that the sewage and oxygen can be fully mixed and contacted to complete the biochemical process.

Product Features

The BZS2 series rotary brush aerator is a second design that has been improved and enhanced based on the success of the BZS model. The product has the following characteristics:

1) The dedicated spiral cone cylindrical gear reducer driven by a vertical electric motor has a small footprint, easy process layout, and a large distance between the motor and the liquid surface, greatly reducing the impact of sewage mist on the insulation performance of the motor;

2) The tail bearing structure of the rotary brush aerator is reasonable, and easy to assemble, inspect, and maintain;

3) There are two types of rotary brush aerators according to the type of reducer: G and Z, with G being foot mounted and Z being shaft mounted.

G-type: The transmission end of the rotary brush does not have a bearing seat, and the output shaft of the reducer is connected to the rotary brush shaft through a coupling; When replacing vulnerable parts and repairing the gearbox, temporary supports should be provided for the rotating brush components; The coaxiality requirements for the tailstock and gearbox output shaft are high, installation is complicated, and high precision is required.

Z-type: The rotating brush transmission end is equipped with an additional bearing seat, without the need for a coupling; When replacing vulnerable parts and repairing the gearbox, keep the rotating brush components in their original position; The gearbox is easy to install and does not require centering. The installation accuracy requirement for the whole machine is low.

4) The load and oxygen level can be changed by adjusting the immersion water level through design.

product structure

BZS2 consists of a vertical motor, a spiral cone cylindrical gear reducer, a main shaft, brush blades, a tail end bearing seat, a lubrication system, and a control cabinet. Brush blades are evenly distributed on the main shaft, and the rotating brush rotates rapidly under the drive of the driving device. The brush blades throw water into the air, forming a water jump and fully contacting the air. The air quickly dissolves in the water, achieving the purpose of oxygenation. At the same time, the brush blade has a flow pushing effect on the water, allowing it to circulate and constantly update the water surface, keeping the activated sludge in a suspended state.
