Description
Technical field
It the utility model is related to the equipment to combustion apparatus supply and pulverized fuel, more particularly to a kind of medium-speed pulverizer one
Secondary wind powder selectivity distributor.
Background technology
Medium-speed pulverizer is a kind of conventional coal pulverizer of thermal power plant, and its operation principle is that coal falls into mill, coal from coal spout
It will be thrown at mill bowl by centrifugal force after falling into mill and complete to mill with drying at vane, and then be blown to whizzer
Complete separation in place.
Because medium-speed pulverizer uses centrifugal separation, so residual rotation be present, although setting up venturi equipartition device,
But residual rotation still influences coal dust and evenly distributed, make the coal dust in four primary air pipings that the coal spout of medium-speed pulverizer connects
Simultaneously relatively large deviation is presented in density unevenness.This deviation directly affects temperature field in boiler, combustion atmosphere, coal dust burn-out degree etc.,
More likely cause boiler scaling, heating surface by high temperature corrosion, the final safe and economical operation for influenceing boiler.
Utility model content
In order to solve the above technical problems, the purpose of this utility model, which is to provide a kind of coal dust, divides equally that effect is good, space-consuming
It is small, by the small medium-speed pulverizer primary wind and powder selectivity distributor of resistance.
A kind of medium-speed pulverizer primary wind and powder selectivity distributor of the present utility model, located at the First air of medium-speed pulverizer
Guan Shang, including some fender plate mechanisms being evenly arranged along primary air piping entrance excircle, each fender plate mechanism include
The baffle installation base and baffle plate, the baffle plate for being fixed on the outlet periphery of primary air piping are rotatably mounted to baffle installation base
On, plane where each baffle plate is perpendicular with the radial direction of primary air piping, and all baffle plate synchronous rotaries are with uniform water conservancy diversion.
Further, the baffle plate anglec of rotation is 360 degree.
Further, the primary air piping entrance periphery has been evenly arranged 12 baffle mechanisms.
Further, the baffle installation base includes being fixed on the swash plate, base and helical axis of primary air piping avris, described
Base runs through and is fixed on swash plate, and the bottom of the baffle plate is screwed in base center by helical axis, is set on the base
There is the latch fitting being adapted to helical axis.
By such scheme, the utility model at least has advantages below：The utility model is mainly used in medium-speed pulverizer
The coal dust of primary air piping is divided equally, and on the entrance periphery of primary air piping, is evenly arranged the baffle plate of achievable 360 degree of rotations, because
Wind powder stream has tangential-velocity component and axial velocity to outlet cylinder, determines that wind powder stream is absolute by calculating or numerical simulation result
The angle of speed and primary air piping pelvic outlet plane normal direction, and with this as the approximate baffle plate anglec of rotation, uniform water conservancy diversion so that four
Coal powder density at individual primary air piping is uniform, can optimize combustion atmosphere in stove, coal dust burn-out degree；Structure letter of the present utility model
It is single, occupy little space, cost it is low, the what is more important medium-speed pulverizer primary air piping selectivity pulverized coal distributor actually makes
Occupied little space during, be small by resistance.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is the structural representation of medium-speed pulverizer primary wind and powder selectivity distributor；
Fig. 2 is the cross section structure schematic diagram of medium-speed pulverizer primary wind and powder selectivity distributor.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Referring to Fig. 1-2, the medium-speed pulverizer primary wind and powder selectivity distributor of the preferred embodiment of the utility model one, it is located at
On the primary air piping 1 of medium-speed pulverizer, including 12 fender plate mechanisms being evenly arranged along the entrance excircle of primary air piping 1,
Each fender plate mechanism includes the baffle installation base for being fixed on the outlet periphery of primary air piping 1 and baffle plate 3, baffle plate 3 are rotatable
Be arranged on baffle installation base on, each place plane of baffle plate 3 is perpendicular with the radial direction of primary air piping 1, and all baffle plates 3 are same
Step rotation is with uniform water conservancy diversion；Preferably, baffle installation base includes being fixed on the swash plate, base 2 and helical axis of the avris of primary air piping 1
4, the connection swash plate of medium-speed pulverizer tank outlet and primary air piping 1 can use directly as above-mentioned swash plate, and base 2 runs through and consolidated
It is scheduled on swash plate, the bottom of baffle plate 3 by helical axis 4 is screwed in the center of base 2 to realize that baffle plate 3 rotates, moved up and down, base
It is provided with the latch fitting being adapted to helical axis 4 on 2, in actual water conservancy diversion, is mainly spun and be connected simultaneously in the center of base 2 by helical axis 4
Come the anglec of rotation of controllable register 3 and moved up and down by spiral；At the top of 12 baffle plates circle is formed in the top of primary air piping 1
Shape shrinks mouth structure, drives baffle plate 3 to move up and down to adjust the bore of rounded constrictions mouth structure by the spiral of helical axis 4, and
And the face on the basis of plane where the axis of baffle plate 3 and the axis of primary air piping 1, the spiral of micro-adjustment helical axis 4 drive 3 turns of baffle plate
The angle of plane and reference plane where to it is that 0-50 degree is advisable；After reaching specified angle and position, pass through latch fitting locked flapper
With uniform water conservancy diversion.
A kind of use of medium-speed pulverizer primary wind and powder selectivity distributor of the present utility model, can again auxiliary inlet louver with
Itself axle, which turns an angle, suppresses the powder amount that coal dust enters corresponding primary air piping 1, even if blade is adjusted without rotating, due to
Itself racemization to air-flow, it can also improve the uniformity of coal powder distribation.
It the above is only preferred embodiment of the present utility model, be not limited to the utility model, it is noted that for
For those skilled in the art, on the premise of the utility model technical principle is not departed from, if can also make
Dry improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
