Accompanying drawing explanation
Fig. 1 is the structural representation of flyash of the present utility model three grades of separators.
Detailed description of the invention
Shown in composition graphs 1, this kind of flyash three grades of separators, comprise: rolling device 41, funnel 42 and bulky grain separated and collected device 43, rolling device 41 is communicated with bulky grain separated and collected device 43 via funnel 42 by the first discharging opening 41a be opened in bottom it, after motor 7 drives rolling device to be milled by raw meal coal ash, bulky grain flyash enters into bulky grain separated and collected device 43.The motor-driven vibratory sieve (not shown) be arranged in this bulky grain separated and collected device 43 carries out Preliminary screening to bulky grain flyash.
This device also comprises the first separation bin 11, reject fly ash gathering-device 12, second separation bin 21, middle flyash gathering-device 22, the 3rd separation bin 31, fine powdered coal gathering-device 32 and centrifugal blower 5.Second discharging opening 41b of this rolling device 41 is connected with the top of the first separation bin 11 by feed pipe (pipe thicker shown in figure) via funnel 42, and the bottom of the first separation bin 11 is communicated with reject fly ash gathering-device 12.The bottom of this first separation bin 11 is connected by the charging aperture of feed pipe with this second separation bin 21 top, and the bottom of the second separation bin 21 is communicated with middle flyash device 22.The top of this first separation bin 11 is connected by the charging aperture of feed pipe with the top of the 3rd separation bin 31, and the bottom of the 3rd separation bin 31 is communicated with fine powdered coal device 32.The air outlet of centrifugal blower 5 passes through discharge pipe (shown in figure, pipe thin compared with feed pipe) be connected with the bottom of the first separation bin 11, air inlet is connected with the top of the second separation bin 21 and the 3rd separation bin 31 by two blast pipes (shown in figure, pipe thin compared with feed pipe) respectively via threeway.
In addition, in order to strengthen feeding efficiency, carry out air blast to flyash before entering separation bin, the feed pipe place between funnel 42 and the first separation bin 11 is provided with conveying worm 6 (i.e. auger).This second discharging opening 41b is opened in the side-lower of described rolling device 41, a little more than the first discharging opening 41a, can further improve the collection efficiency of flyash.Described feed pipe preferably adopts the carbon steel pipe that intensity is higher, and its wall thickness is 2mm, and internal diameter is 150mm.This discharge pipe and blast pipe are then preferably lighter weight, and lower-cost pvc pipe, its wall thickness is 3mm, and internal diameter is 150mm.The diameter of described first separation bin 11 is 350mm, and height is 1000mm, and the diameter of described second separation bin 21 is 200mm, and height is 800mm, and the diameter of described 3rd separation bin 31 is 200mm, and height is 800mm.Each carse, medium and small flyash gathering-device described is preferably flyash collecting box.Each separation bin top adopts flat-tope structure, and bottom adopts conical bottom.Be conducive to the recovery of the collection of flyash and air quantity, balance like this.
Raw meal coal ash is after milling, bulky grain separated and collected device is entered after primary dcreening operation, the particle of super large returns device for grinding to be continued to mill, particle up to standard enters the first separation bin through conveying worm, and before entering separation bin, separation bin shifts to an earlier date air blast, particle is allowed to move at separation bin internal cyclone, bulky grain, in motion process, by Action of Gravity Field, drops in reject fly ash collector.Middle granular powder coal ash, in decline process use, reaches cyclonic wind when being greater than gravity, enters the second separation bin with the wind from pipeline, transient flow prompt drop is low, middle particle gravity is greater than suspending power, and be collected in middle flyash collector, wind gets back to centrifugal blower from top by ajutage and threeway.Fine grained flyash enters the 3rd separation bin from the first separation bin, and tiny particle slows down instantaneously, and when gravity is greater than suspending power, be collected in fine powdered coal collector, wind gets back to centrifugal blower from top by ajutage and threeway.
Flyash of the present utility model three grades of separators are fully being summed up on traditional separator basis, and adopt the principle of cyclonic separation, according to the gravity characteristic of different flyash, quantity-adjustable size, reaches the collection of three grades of different flyash.
Above-described embodiment is for illustrative principle of the present utility model and effect thereof, but the utility model is not limited to above-mentioned embodiment.Those skilled in the art all without prejudice under spirit of the present utility model and category, in claims, can modify to above-described embodiment.Therefore protection domain of the present utility model, should cover as claims of the present utility model.
