Description

Suspension type low-speed impeller

Technical Field

The utility model relates to a water treatment facilities technical field specifically is a suspension type is low-speed impeller under water.

Background

The submersible water impeller and the surface aeration impeller are important means and equipment for the treatment process of the activated sludge method, and have advantages and disadvantages respectively. The surface aeration impeller has the advantages that the equipment is arranged on the water surface, is convenient to maintain and is not easy to damage, and the defects that a pool (ditch) cannot be too deep are overcome, so that the occupied area and the investment of civil facilities are greatly increased. The submersible water impeller has the advantages that the depth of a pool (ditch) can be increased, so that the occupied area and the investment of civil facilities are reduced, and the flow velocity of a water body is more uniform. The defect is that after the sealing device is used for a period of time, the motor is easy to be burnt out by water due to the abrasion of the sealing element, and meanwhile, the fixed guide rod can cause fatigue failure or loosening and damage of the underwater foundation bolt due to the huge alternating stress generated when the impeller works. Because the fixed guide rod base is arranged at the bottom of the water tank, the repair is very difficult, water needs to be completely pumped out, local or even complete production stop of a sewage treatment plant is caused, and thus, environmental pressure and economic loss are brought to the sewage treatment plant and the local area.

The utility model provides a simple and practical novel water plug flow and stirring device which integrates the advantages of a submersible plug flow device and a surface aeration plug flow device and avoids the defects of the submersible plug flow device and the surface aeration plug flow device.
