Product Description

Purpose:
The screw aeration mixer has the function of one machine for two purposes, which can be used for aeration and mixing. It is mainly used for urban domestic sewage treatment, industrial wastewater treatment and fishpond oxygenation. The machine is applicable to:
1. Suitable water depth 3~M long;
2. Aeration and agitation of SBR biochemical tank;
3. Aerobic aeration and anaerobic agitation for biological nitrogen and phosphorus removal treatment;
4. Activated sludge aeration and agitation;
5. Oxidation pond.

Features:
1. Compact structure, small floor area and less investment.
2. It has the function of one machine for two purposes, which can be used for aeration and mixing. No blower is required for aeration.
3. Simple operation and maintenance, convenient and fast installation.
4. The operation can be automatically controlled according to dissolved oxygen for automatic control.

Electrical control:
Normal local button control. Automatic control of the system, real-time dynamic detection of aeration tank operating parameters and equipment operating status, program control of the operation of relevant equipment, and automation of the process.

Structure and working process:
The spiral aeration mixer consists of a motor, support, coupling, guide cylinder, spiral blades, and main shaft. It features two groups of spiral blades: one above the water surface and one below. During aeration (forward rotation), the lower blades drive water into the upper blades, which then expel it in a curtain shape, creating a hydraulic jump that introduces air and dissolves oxygen into the sewage. This process ensures extensive contact between sewage and air, promoting effective oxygenation. In stirring mode (reverse rotation), the lower blades circulate water in the pool while the upper blades remain inactive.

Product structure introduction:
The equipment is mainly composed of vertical motor, support, supporting tube, impeller and displacer or fixed support. As shown in the figure:
