Equipment generally includes air pump and aeration tube, although novel aerator emerges one after another, but current 2 classes that still can be divided into: the
1 kind is to generate the method that oxygen is transmitted water inlet solution by air bubble using the porous diffusion tip or air nozzle of submerged, also known as
Jet-flow aeration and air blower aerating system are called, the 2nd kind is to promote the oxygen in atmosphere to be dissolved in water using mechanical means stirring-up sewage
Method, appellation mechanical aeration system micro-pore aeration, be aerated diffusion tip layout and aerating system adjusting these be all energy-efficient
Effective measures.
Novel profile oxidation treatment device described in the present embodiment, the walking hoisting mechanism is also known as overhead traveling crane, bridge-type rises
Heavy-duty machine；It is a kind of crane span structure type crane that gantry is run on aerial conveyor.The gantry edge of bridge crane is laid on two sides height
Track on frame is longitudinally running, and trolley is laterally run along the track being laid on gantry, constitutes the working range of a rectangle,
The space handling material below gantry can be made full use of, not by the obstruction of ground installation.Bridge crane is widely applied
Outer warehouse, workshop, harbour and outdoor yard etc. indoors.Bridge crane can be divided into ordinary bridge crane, simple fine strain of millet
Dedicated three kinds of bridge crane with metallurgy of bridge crane.Ordinary bridge crane generally by trolley, gantry operating mechanism,
Gantry metal structure composition.Trolley is made of lifting mechanism, wheeling mechanism and trolley frame three parts again.Lifting mechanism
Including motor, brake, retarder, reel and pulley blocks.Motor drives spool turns, makes wirerope by retarder
It is put down around coiling or from reel, to go up and down weight.Trolley frame is rest and the installation portions such as lifting mechanism and wheeling mechanism
The rack of part, usually welding structure.The driving method of crane travel mechanism can be divided into two major classes: one kind is centralized driving,
The adhesion wheel on long transmission shaft driving both sides is driven with a motor；It is another kind of for respectively drive, i.e. the active vehicle on both sides
Take turns each motor drive.Medium and small bridge crane relatively mostly uses brake, retarder and motor unit integrator
" three-in-one " driving method, the ordinary bridge crane of big elevating capacity is to be easily installed and adjust, and driving device is frequently with ten thousand
To shaft coupling.Crane travel mechanism is generally only commonly used if lifting capacity is very big with four actives and driven wheel and increases wheel
Method reduce wheel load.When wheel is more than four, it is necessary to use articulated balance bicycle frame device, make the uniform load of crane
Ground is distributed on each wheel.The metal structure of gantry is made of main fine strain of millet and end fine strain of millet, is divided into single main fine strain of millet gantry and double two classes of fine strain of millet gantry.
End fine strain of millet of single main fine strain of millet gantry by single main fine strain of millet and positioned at span both sides forms, and double fine strain of millet gantries are made of two main fine strains of millet and end fine strain of millet.It is main
Fine strain of millet and end fine strain of millet rigid connection, end fine strain of millet both ends are equipped with wheel, to support gantry in overhead upper operation.It is welded with track on main fine strain of millet, supplies
Trolley operation.The structure type of the main fine strain of millet of gantry is more to have box structure, fort truss structure and vierendeel truss than more typical
Structure.It is several that box structure can be divided into the double fine strains of millet of right path box-shaped, inclined rail box-shaped double fine strain of millet, the inclined main fine strains of millet of rail box-shaped list etc. again.Right path box-shaped
Double fine strains of millet are a kind of citation forms being widely used, and main fine strain of millet is made of the vertical web of upper and lower flange plate and two sides, trolley rail cloth
It sets on the center line of top flange plate, its structure is simple, and easily manufactured, suitable for producing by batch, but it is larger to be self-possessed.Inclined rail box-shaped
All by upper and lower flange plate and the major-minor web of uniform thickness does not form in the section of double fine strains of millet and the inclined main fine strain of millet of rail box-shaped list, trolley rail cloth
It sets above main web, the intracorporal short stiffener of case can save, wherein the inclined main fine strain of millet of rail box-shaped list is by a wide width wing edge box-shaped
Main fine strain of millet replaces two main fine strains of millet, is self-possessed smaller, but manufactures more complex.Four truss structures are combined into enclosed type by four plate plane truss
Space structure is generally covered with away platen on upper horizontal truss surface, and from heavy and light, rigidity is big, but compared with other structures, shape ruler
Very little big, manufacture is more complex, and fatigue strength is lower, less production.Open-web truss structure is similar to the inclined main fine strain of millet of rail box-shaped, by four steel
Board group is cut into perhaps on remaining three pieces steel plate according to design requirement in addition to main web is the I-shaped fine strain of millet of real abdomen at an enclosed construction
Multiwindow forms a vierendeel truss without brace, is covered with away platen, crane travel mechanism on upper and lower horizontal truss surface
And electrical equipment is self-possessed lighter, overall stiffness is big, this is in a kind of pattern that China is relatively broad use inside gantry.
Ordinary bridge crane mainly using being driven by electricity, usually manipulates in drivers' cab, also there is far distance control.Lifting capacity can
Up to 500 tons, span is up to 60 meters.Simple bridge type crane is also known as fine strain of millet formula crane, structure composition and common overhead traveling crane
Machine is similar, and lifting capacity, span and operating rate are smaller.The letter that the main fine strain of millet of gantry is made of I-steel or other fashioned iron and slab
Single section fine strain of millet uses chain block or electric block to mix Simple small as trolley, and trolley is generally in the bottom wing of I-shaped fine strain of millet
It is run on edge.Gantry can also be run, this crane along the track operation on overhead along the track being suspended in overhead below
Referred to as hang fine strain of millet formula crane.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
