Embodiment Construction
[0007] As shown in the figure, the submersible vortex air flotation device of the present invention adopts submersible motor 1 and Frame 2 structure, external air enters diffuser impeller 3 through air inlet pipe 4. The high-speed rotation of the air-dispersing impeller 3 creates negative pressure inside the impeller, so that the outside air enters, and uses the cutting effect of the blades of the air-dispersing impeller 3 to make countless fine bubbles of the inhaled air, thereby realizing air dissolution.

The invention discloses a submerged cavitation air floatation device, which is characterized in that a submerged motor and a submerged rack mechanism are employed. The submerged motor installed under water drives an air dispersion impeller on the rack to rotate at a high speed to form negative pressure, so that external air is fed into the air dispersion impeller through an air inlet pipe. The air dispersion impeller under high speed rotation cuts air into countless small bubbles to achieve gas dissolution. By means of the arrangement, the invention solves the difficult problems that a cavitation air floatation hollow shaft is too long, the bearing and the sealing structure are liable to damage and the device is excessive high in repairing workload. Because the transmission shaft of the submerged cavitation air floatation device is short, the device can achieve energy saving, is light in mass, is novel in design and is easy to move and repair.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a submersible vortex-concave air flotation device. Background technique [0002] In the sewage treatment fields such as papermaking, petroleum, slaughtering and processing, the vortex concave air flotation device is widely used because of its simple equipment and easy operation and maintenance. As the core equipment of the vortex concave air flotation device, the CAF air flotation machine, because the diffuser impeller is installed underwater, the supporting transmission and air intake hollow shaft will be very long, sometimes as long as 1.5m, and the impeller needs to rotate at high speed, bearing and sealing It is easy to be damaged, and the maintenance amount is very large, and its whole is very heavy, and the maintenance is very loaded down with trivial details. Contents of the invention [0003] The invention proposes a submersible vortex-concave air flotation device, whic...
