Description
Technical field
The invention belongs to the environmental protection installation technical field, relate to the two turbine stirrers of a kind of vertical shaft type.
Background technology
In the urban sewage treatment process; The stirring of mixed liquor is a critical process wherein; Mostly that uses at present is the horizontal double bladed paddle of impeller shaft, leafy slurry agitator etc.; The version of these blades, the stirring demand to specific all plays a role; But more or less come with some shortcomings, for example: much such as the stirring region local velocity, as to pass impeller mud group is broken easily, have certain stirring dead angle, drive motors, reductor safeguard that relatively difficulty, impeller are linked with impurity etc. easily under water.And the higher 5～8W/m that reaches of common agitator power density

Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of and stir, gentleness, anhydrous consumable accessory down, the two turbine agitators of vertical shaft that installation and maintenance are easy.
The object of the invention is realized through following technical scheme:
The two turbine stirrers of a kind of vertical shaft type comprise the parallel gears reducing motor, the flexible fastening pedestal; Hollow drive shaft, the turbine stirring impeller is formed, and the parallel gears reducing motor is installed in through the flexible fastening pedestal and installs on the basis; Hollow drive shaft one end links to each other with the parallel gears reducing motor; The other end is connected with the turbine stirring impeller, and described turbine stirring impeller is the indent taper, and indent taper arc surface inboard has long water conservancy diversion to stir rib and short-range missile stream stirring rib along circle distribution; Said long water conservancy diversion stirring rib and short-range missile stream stir the rib space and are interspersed, and promptly per two adjacent long water conservancy diversion stir and are provided with short-range missile stream stirring rib between the rib.
Said long water conservancy diversion stirs rib along formula involute shape distribution in the shape of a spiral on the turbine stirring impeller indent taper arc surface, and long water conservancy diversion stirs the extending line intersection point of rib and the center of circle of turbine stirring impeller is all dropped on the extended line of hollow drive shaft; Short-range missile stream stirs rib along formula involute shape distribution in the shape of a spiral on the turbine stirring impeller indent taper arc surface, and short-range missile stream stirs the extending line intersection point of rib and the center of circle of turbine stirring impeller is all dropped on the extended line of hollow drive shaft.
It is identical with the bar number that short-range missile stream stirs rib that described long water conservancy diversion stirs rib, is 6～10, and the bar number that preferably long water conservancy diversion stirring rib and short-range missile stream stir rib is each 8.
The whole weight of the two turbine stirrers of vertical shaft type is stressed to be supported on (crane span structure is concrete foundation or steel bracket) on the erection bridge; Approach at the bottom of the pond position of the two turbine stirring impellers of high strength glass material; Bearings is not established in the bottom; Be connected with the parallel gears reducing motor through cantilevered stainless steel (or fiberglass) hollow drive shaft, and transmit moment of torsion by the parallel gears reducing motor.
Be connected through flange between turbine stirring parts and the hollow drive shaft, loosening during with anti-rotation.The agitator operation can the oneself be entangled the position, and the downward force that is in operation vertically prevents to produce uneven motion.
Beneficial effect:
Mixer of the present invention is installed in anaerobic pond, the anoxic pond, creates an occasion of almost completely mixing, do not have the deposition homogeneous, is beneficial to the metabolism of biological bacteria, organic degraded, reaches the effect of denitrification denitrogenation.Be installed in the aerobic section of biological respinse, help prolonging the oxygen time of staying of input, improve The oxygen transfer efficiency for aerator.
Experiment showed, that the two turbine stirrers of vertical shaft type of the present invention have following technical advantage:
(1) two turbine stirring impellers arrange evenly that at interval long water conservancy diversion stirs rib and short-range missile stream stirs rib, and water conservancy diversion stirs rib and produces thrust, can make medium produce circular motion; Medium is rolled up and down; Make medium reach the three-dimensional effect that stirs of mixing, guarantee the homogeneous media mixing, do not have the dead angle.The mixing stirring capacity that the two turbine stirrers of vertical shaft type of the present invention produce improves more than 20% than the stirring disk that long water conservancy diversion stirring rib only is set, and the impeller service area of same diameter promotes more than 20%, and its power density is about 1.5～2.0W/m
3, want that for mixer under the traditional water vertical shaft is two, and turbine agitator is energy-conservation reaches more than 50～60%;
Liquid passed through impeller or an impeller that rotates at a high speed when (2) existing agitating device was under water worked; Under high-speed stirred, possibly destroy mud group owing to mechanical friction power; And the two turbine stirring impellers of mixer of the present invention arrange evenly that at interval long water conservancy diversion stirs rib and short-range missile stream stirs rib; When rotating, two turbine stirring impellers in fluid media (medium), produce one 360 ° homogeneous flow fields of rolling up and down; Create the environment of a gentleness, homogeneous, can protect mud group not to be destroyed, help the metabolism and the organic degraded of biological bacteria.And mixer rotary speed of the present invention is no more than about 2m/s.This also makes it can not destroy mud group.
(3) mixer does not have consumable accessory under water, and parts all adopt long-lived stainless steel or fiberglass material to make under water, and long service life adopts the flexible fastening bearing to install between drive unit and the erection bridge, eliminate vibrations, and complete machine is realized non-maintaining operation basically.
(4) novel parallel gear reduction motor is installed on the erection bridge on the water surface through the flexible fastening pedestal, and the flexible fastening pedestal can move the vibrations that produce by abatement apparatus, reduces the impact load to reducing motor, prolongs service life of equipment.
The present invention is applicable to circular pond, square pond and other irregular pond types; Be applicable to various types of sewage treatment process; For example various fluids such as oxidation ditch, AAO, SBR, SBBR, CASS, CAST, sludge digestion, the sterilization dosing occasion that need mix stirring is particularly useful for mixing of various sewage treatment process anaerobism, anoxic section.
