Description
Technical field
The present invention relates to a kind of coal pulverizer, more particularly, relate to the vertical spindle coal pulveriser of the convenient maintenance in fan position.
Background technology
Coal pulverizer is after material is broken, then the key equipment of pulverizing.Coal pulverizer is widely used in cement, silicate product, and the production industries such as New Building Materials, refractory material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics, carry out dry type or wet type grinding to various ores and other grindability material.
Problem is, the discharge how effectively rear coal dust is pulverized in adjusting, and reducing the pollution of environment is the problem that needs solution.
Summary of the invention
A kind of novel energy-conservation coal pulverizer of the present invention, this equipment can significantly reduce sends out firepower electrical plant energy consumption, improves energy utilization rate, especially can effectively control the outside discharge of coal dust, thereby reduce the pollution to environment.
In order to achieve the above object, the invention provides a kind of coal pulverizer, vertical setting; From top to bottom, coal dust outlet is set respectively successively, is provided with the grinding table in coal-grinding storehouse, described grinding table bottom is provided with to the air inspiration device of drying in described coal-grinding storehouse; The main shaft of described air inspiration device is connected in planetary reducer the driven rotary of below; The main shaft of the power shaft of described grinding table and described air inspiration device coaxially arranges; Described air inspiration device comprises the exhausting blade that main shaft drives, and air intake; Described porch is provided with entrance adjusting vane; Described entrance adjusting vane is arranged on the support of porch in hinged way, and is fixed by locking member.
Under optimal way, on entrance adjusting vane one side body of described air inspiration device, offer maintenance and regulate mouth, and hermatic door is set.
In the course of the work, air inspiration device can be adjusted the capacity of air to coal pulverizer of the present invention, thereby controls the situation that coal dust is discharged, and under the condition of meet the requirement of environmental protection, meets need of production.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of coal pulverizer of the present invention.
Fig. 2 is the enlarged diagram of coal pulverizer air inspiration device of the present invention.
Fig. 3 is the local structure for amplifying schematic diagram of Fig. 2 Leaf part.
The specific embodiment
As shown in Figure 1, coal pulverizer of the present invention, is characterized in that, vertical setting; From top to bottom, coal dust outlet 3 is set respectively successively, is provided with the grinding table 4 in coal-grinding storehouse, described grinding table 4 bottoms are provided with to the air inspiration device of drying in described coal-grinding storehouse.Outlet 3 is communicated with coal-grinding storehouse.In figure, grinding table 4 relies on the inner grinding roller 5 arranging to reach coal-grinding object, and its structure can be selected the coal pulverizer coal-grinding structure of prior art.In addition, the main shaft of air inspiration device is connected in planetary reducer 1 driven rotary of below; The main shaft of the power shaft of described grinding table 4 and described air inspiration device coaxially arranges.
As shown in Figures 2 and 3, described air inspiration device comprises the exhausting blade that main shaft drives, and air intake 11; Entrance 11 places are provided with entrance adjusting vane 12; Entrance adjusting vane 12 is arranged on the support of porch in hinged way, and is fixed by locking member.Under optimal way, on entrance adjusting vane 12 1 side bodies, offer maintenance and regulate mouth, and hermatic door 13 is set, due to the angle of artificial adjusting vane, control the size of entrance.
During coal pulverizer work of the present invention, grinding table is by planetary reducer driven rotary, and there is screeding device its underpart.Mill watt is fixed on grinding table along with rotation, the passive rotation of roller frictionally, and execute and carry by plunger pressurization, thereby the coal cinder that centre is fallen grinds.Bottom pedestal has input air mouth, blows the coal dust grinding, and by rotary separator, coal dust is taken away.Rotary separator is driven by motor gyroaxis, sharf rotation.Grinding roller is loaded as hydraulic loaded, and hydraulic cylinder is with accumulator, better controls the unstability of the noise, vibration and the middle fault that produce due to hydraulic pulsation.Bottom and middle pedestal all have protection abrasion-proof backing block, and structural design is more optimized.
In addition, the present invention can select speed change " cone cylinder " formula coal pulverizer, cone cylinder shell dwindles to powder delivery is distolateral, different with other mill, this mill is that complete machine is contained in " bedframe " above, tilting its longitudinal axis that makes of cone barrel shell can be become to micro-inclination angle with level, and the tilting degree of shell can regulate along the steel ball in housing total length and fill ball coefficient, become a kind of brand-new effectively regulating measure, it available manually or robot control system(RCS) make shell tilt to reach requirements.The major advantage of this coal pulverizer:
1, all steel balls can be pressed the large and small edge of a sphere diameter cone cylinder total length cross sections automatic classification, the cast and decline movement of realizing ideal; The best cast and decline movement of steel ball and with barrel dliameter, become widely differently turn general and can seamlessly transit; The ball coefficient that fills on cone cylinder total length cross sections guarantees that steel ball cast and decline movement is for best;
2, can regulate voluntarily the large and small optimum state (dispensing out average suspension steel ball) that reaches of steel ball;
3, coordinate to merge large and small diameter (becoming L/D) grinding machine is excellent, shortcoming, maximize favourable factors and minimize unfavourable ones, realization is optimized integration;
4, borrow the inclination angle changing between the cone cylinder longitudinal axis and level to tackle concrete coal, to being that the identical ball coefficient that fills is corrected originally, redistribute the forward and backward ball load of grinding machine, make grinding machine running operation optimization; Casing only tilts slightly, just can alleviate ball to end cap pressure, and wearing and tearing are mutually alleviated;
5, be the housing aerodynamic characteristics of contracting nozzle shape excellent;
6, because steel ball cast and decline movement is strictly followed with grinding machine radius change relation.Not because armor smoothly makes a variation, therefore armor shape exterior feature is unimportant to grinding machine running;
Therefore 7, wear and tear because ball load is best and correspondingly alleviate 30%.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
