Description
Technical field
The present invention be to water treatment with the improvement of aeration rotary brush, relate in particular to that a kind of plug-flow ability is strong, energy consumption is low, the aeration rotary brush of high oxygenation, long service life.
Background technology
Change brush since rotating speed relatively than the rotating disk height, being used for water treatment, to have a plug-flow flow velocity fast, the oxygen-transfer efficiency height, this is its advantage, but energy consumption is relatively than the rotating disk height, dynamic efficiency is low, and restricted by blade strength, diameter generally is no more than 1 meter, so the relative rotating disk of operating depth is more shallow, operating depth generally is no more than 3.5 meters, and this is its deficiency.Prior art aeration rotary brush, basic structure comprise the center hub axle sleeve and be fixed on the commentaries on classics brush blade of wheel hub axle sleeve circumference uniform distribution, and the typical case is as described in Chinese patent CN2175226, the CN2216524.People further improve to change the brush oxygenation capacity, have done some improvement to changeing the brush blade, and for example the described commentaries on classics brush of Chinese patent CN2425920 blade is provided with groove in the middle of leaf cross-section; The shearing blade of the disclosed transverse axis brush aeration of Chinese patent CN2157188 machine, zigzag structure is adopted in its both sides.But no matter which kind of blade done improve, it all is straight structure without exception that blade is brushed in existing commentaries on classics, has all changed since the invention of rotation brush, has become the popular one-tenth of industry.
The straight structure blade, high rotating speed changes in the water fast when aeration is worked, and the blade whole plane strikes waters, not only to go into water resistance big for blade, increased power consumption, starting current and running current are all bigger, and this also is to cause dynamic efficiency to be usually less than a reason of rotating disk; And the water surface is big to the blade surging force, and long time continuous working causes the metal blade bending easily, fractures at last, and shorten work-ing life, increased the maintain and replace workload; Secondly, the straight blades running resistance is big, and rotating speed can not improve (existing the highest 72 rev/mins), therefore is difficult to improve oxygen-transfer efficiency again.Besides, straight blades is little to bottom plug-flow ability, thereby operating depth is more shallow relatively, 1 meter long blade for example, and maximum operating water depth is no more than 3.5 meters.For this reason, people for example are generally about 3 meters in brush aeration device downstream usually flow deflector are set, and increase bottom velocity by reducing surface velocity.Though increased bottom velocity and increased operating depth yet flow deflector is set, also can improve oxygenation capacity, but set up flow deflector and can worsen flow condition, test shows increases flow deflector need increase the 15-30% power consumption, thereby dynamic efficiency does not only improve, descend to some extent on the contrary, therefore actual and uneconomical.
In addition, existing commentaries on classics brush blade all adopts metal blade without exception and separates with the wheel hub axle sleeve, adopting bolt to be fastened on hub spindle during installation puts, this structure not only leaf weight is relatively large, cause commentaries on classics brush operating load big, the operation power demand is also big, and this also is another not high reason of its dynamic efficiency; And blade installation workload is big piecewise, difficulty is high, the long-play vibration that strikes waters also causes bolt looseness easily, comes off at last, need to replenish increases, and has also increased the maintain and replace workload.Therefore still having is worth improved place.
