Description
Technical field
The utility model belongs to water treatment facilities, and in particular to a kind of air blower for sewage disposal.
Background technology
The Sewage Treatment Project of accounting row 90% is the work for organic sewage, and indispensable in organic dirty process flow
Process is aerobe purification --- it is 20-60Kpa, finely dispersed air, the work to provide pressure to cesspool bottom
One of blast apparatus used in skill is rotary blower.
Existing rotary blower is by air intake filter, wind drum, the rotor being located in wind drum and can radially slide in the rotor
Dynamic 4 pieces of blades, air outlet, oil/water knockout drum, Lubricating oil tank, pedestal, driving motor, belt and the skin being located on wind drum
The components such as belt wheel form.In terms of operating condition, the problem of being primarily present, has this air blower：First, fixed air compartment（It is generally called wind drum,
Usually cast member）It is the ferrous material based on iron with material used by high-speed rotating blade.Due to air pressure
The clearance requirement of the needs for this function that contracts, wind drum and blade is the smaller the better.But blade and the intermetallic abrasion of wind drum are not
Evitable, therefore, the working efficiency of wind turbine, service life are unsatisfactory.Secondly, but due to steel blade and cast iron rotary drum it
Between friction, make that the maintenance cycle of equipment is short, service life is restricted, and with the increase of blade and wind drum abrasion, operating
Resistance and noise also increase, therewith until cannot use.Again, frictional resistance is big between wind drum when blade high-speed rotation, needs
Mineral grease lubrication is filled, the mineral grease part being lost in operational process has been entered in sewage with compressed air, aggravated
The pollution of water.
Utility model content
The purpose of this utility model is to provide a kind of low noise, service life is long, energy-saving and environment-friendly for sewage disposal
Air blower.
The technical scheme adopted for realizing the purpose of the utility model is as follows：
Air blower provided by the utility model for sewage disposal, including wind drum, be located at wind drum in rotor and be located at
The blade of wind drum inner wall can be radially slidingly born against on rotor, the wind drum inner wall is equipped with a polytetrafluoroethylene bushing, institute
Blade is stated using polytetrafluoroethylene (PTFE) blade or the blade of polytetrafluorethylecoatings coatings.
The wind drum is equipped with air inlet, exhaust outlet and water inlet, and the polytetrafluoroethylene bushing is equipped with and the wind
Air inlet, exhaust outlet on drum and the corresponding opening of water inlet.
The beneficial effects of the utility model
1, the polytetrafluoroethylene bushing that the utility model uses resistance to mild wear-resisting property good in wind drum inner wall, and on rotor
It is polytetrafluoroethylene (PTFE) between blade and wind drum when operation using polytetrafluoroethylene (PTFE) blade or the blade of polytetrafluorethylecoatings coatings
Material can greatly reduce abrasion between the two, lower operation noise, improve the service life of air blower and save energy
Source.
2, water inlet is set on wind drum, the blade of high-speed rotation is cooled down and lubricated using water-cooling pattern, both may be used
To protect blade without damage, the service life of equipment is further increased, and not will produce disposal of pollutants, it will not be to environment water
Pollute, thoroughly solve existing air blower using oil cooling but with lubrication belt come pollution problem.
3, there is apparent economic benefit：
1）It is energy saving, it is 7.5kw with power, daily for the rotary blower of operation 12 hours, the sheet of same model
Utility model in comparison, can economize on electricity 6480 degree in year, save about 5000 yuan of expense, save power consumption about 20% or more, every year
Save about 80 liters of 68# steam turbine oils, closes 3200 yuan of RMB；
2）Manufacturing cost is reduced, the utility model can save parts：1 gun barrel；1 usual scarfweld is in pedestal
Interior oil tank；1 set of oil return line；Meanwhile wind drum inside is not required to processing air intake duct, and wind drum, wind drum can be welded with seamless steel pipe
Manufacture material save 40%, process is simpler, and therefore, the total manufacture cost ratio of the utility model is turned round with model tradition
Air blower saves 8~10%；
3）Service life extends, and significantly saves maintenance cost, extends about 4 times of fan repair period, saves the dimension of wind turbine
Repair expense 50%.
4）Noise is reduced, the 1m with model tradition rotary blower is apart from level of noise（dBa）It is 68, the utility model is
32。
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.
