Abstract
The utility model discloses a coal dry method grading plant. The device consists of an air blower 1, a fluidized bed classifier, a coal feeder 9, a dust remover 7 and an induced draft fan 8; the fluidized bed classifier consists of an air chamber 4, an air distribution plate 5, a fluidized bed classification chamber 6, a discharger 2 and a stirring paddle 3. The device adopts wind power for classification, does not need a screen for classification, fundamentally eliminates the problem of screen blockage, is particularly suitable for dry classification of wet fine coal, and has high classification efficiency and stable and reliable operation.
Description
The utility model belongs to a kind of coal dry classification equipment.
The coal classification makes fine coal and beans processing and utilization respectively, has huge energy-conservation and environmental benefit.In recent years, existing many new dry process classifying equipoments come out, as probability screen, and verticle reinforced sieve, rotary screen and piano wire screen etc., but these classifying equipoments are for the still unresolved screen cloth plug-hole of moist fine particulate coal problem, and classification efficiency is lower.
The purpose of this utility model provides a kind of classification efficiency height, and the dry type gradation equipment for coal that operating cost is low especially is suitable for the grading plant of moist raw coal.
Solution of the present utility model is: utilize the device of being made up of air blast, fluidized bed classification device, feeder, deduster and air-introduced machine to make coal be fluidized state in that fluidized bed classification is indoor under the fluidizing agent effect, the desiccation of intergranular mutual collision and fluidizing agent, the fine coal that makes fine coal roll into a ball and stick at coal grain surface is disperseed fast and is come off, wherein take out of outdoor with air-flow less than the fine coal of a certain particle diameter, collect by deduster, and the coal of greater particle size is discharged from the removal device of grading room bottom, thereby reaches effective classification of fine coal and beans.
Be elaborated below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the main TV structure schematic diagram of the utility model paddle 3.
Fig. 3 is the plan structure schematic diagram of the utility model stirring arm 3.
As shown in Figure 1, the utility model mainly is made up of air blast 1, fluidized bed classification device, feeder 9, deduster 7 and air-introduced machine 8; Wherein, the fluidized bed classification device includes air compartment 4, air distribution plate 5, fluidized bed classification chamber 6 from bottom to top, passes air compartment 4 and the removal device 2 that communicates with fluidized bed classification chamber 6 and shaft and pass the stirring arm 3 that air compartment 4 and air distribution plate 5, blade are positioned at fluidized bed classification chamber 6.
By Fig. 2, shown in Figure 3, stirring arm 3 has upper and lower two groups of blades 10 and 11, and blade 10 and blade 11 are installed on the shaft of stirring arm 3 mutually at an angle of 90, and two groups of blade planes become 2 °~20 ° angles with shaft.The effect of stirring arm 3 is mainly: strengthen the horizontal mixing of coal in the fluidized bed classification chamber 6, promote the even distribution of coal that fluidized bed classification chamber 6 can well be moved under the surface bed floor; Large coal particles can be scraped into removal device 2 and discharge fluid bed grading room 6 smoothly, and fragmentation and the dispersion that is used in fine coal group arranged.
The course of work of the present utility model is: fluidizing agent (as: low-temperature flue gas) is gone into fluid bed grading room 6 by air blast 1, air compartment 4, air distribution plate 5 are laggard; Raw coal also enters fluidized bed classification chamber 6 through feeder 9, and the coal in the fluidized bed classification chamber 6 is the fluidized state motion under the fluidizing agent effect.The desiccation of intergranular mutual collision and friction and fluidizing agent, the fine coal that makes fine coal roll into a ball and stick at the lump coal surface can come off fast, disperse, and wherein takes out of with fluidizing agent less than the fine coal of a certain particle diameter, and is collected by deduster 7; Big particle diameter coal is then discharged from removal device 2, thereby reaches effective classification of fine coal and beans.
The utility model is simple in structure, easy operating, classification efficiency height, stable and reliable operation.
Claims (2)
1, a kind of fluid bed coal dry type gradation equipment, mainly by air blast 1, fluidized bed classification device, feeder 9, deduster 7 and air-introduced machine 8 are formed, and it is characterized in that: the fluidized bed classification device mainly includes from bottom to top: air compartment 4, air distribution plate 5, fluidized bed classification chamber 6, pass air compartment 4, air distribution plate 5 and the removal device 2 that communicates with fluidized bed classification chamber 6 and shaft and pass the stirring arm 3 that air compartment 4 and air distribution plate 5, blade are positioned at fluidized bed classification chamber 6.
2, the described fluid bed coal of claim 1 dry type gradation equipment is characterized in that stirring arm 3 is made up of 2 groups of blades 10,11, and blade 10,11 is installed on the shaft of paddle 3 mutually at an angle of 90; Each blade plane becomes 2 °~20 ° angles in two vane group with shaft.
