Description
Affiliated technical field
The present invention relates to a kind of raising material unit of dryer.
Background technology
At present, known blue charcoal is called semicoke or coke powder again, is the block of light/dark balance, generally is to utilize the cleaned coal piece to fire to form; It also can be the industrial adjunct that coal tar is refined in the chemical plant, have fixed carbon height, resistance ratio height, chemism height, contain the characteristic that ash is low, aluminium is low, sulphur is low, phosphorus is low, can replace metallurgical coke, smokeless piece and charcoal and extensively apply in the production of products such as calcium carbide, metallic silicon, ferroalloy, ferrosilicon, ferrochrome, silicomanganese, carborundum, chemical fertilizer, granularity requires to be not less than 5mm.Because the mud that mixes before the blue charcoal oven dry, water content are than higher, drying course is broken easily.Usually the raising material unit that is used in the blue charcoal drier body chamber is " # type ", "+type " or structures such as " Dao types " mostly, all do not solve the problem of drying course material breakage, how breakage rate reduces the problem of drying course material breakage always also in exploration more than 24%.
Summary of the invention
In order to solve prior art material breakage rate problem of higher in the blue charcoal drying course, the invention provides a kind of raising material unit of blue charcoal dryer.
The technical solution used in the present invention is: be arranged on the raising material unit in the rotary barrel 1 that dryer tilts, its lifting blade 2 and stock guide 7 adopt a kind of new construction fully, have increased feedboard 8 and reclaiming plate 9 simultaneously; Wherein: lifting blade 2 is shaped as strip, is vertically connected on the internal face of cylindrical shell 1 circumference, and along the circumference equal distribution, lifting blade 2 has a bending towards center of circle end, towards cylindrical shell 1 direction of rotation; Delivery sheet 8, reclaiming plate 9 are installed in feeding mouth, the discharging opening of rotary barrel respectively, and corresponding one by one with lifting blade; Stock guide 7 is arranged in the chamber of rotary barrel 1, it is shaped as vertical strip, circumferentially impartial arrangement of garden in cylindrical shell 1, with cylindrical shell 1 diameter an angle is arranged, the material that is fallen by lifting blade 2 is just in time accepted in its position, the material receiving end of stock guide 7 has a bending facing to lifting blade 2 towards direction of rotation, and the lifting end electricity of stock guide 7 has a bending to point to rotation in the other direction; From vertical cross section of cylindrical shell, the arrangement architecture of stock guide is " screw type "; Stock guide 7 is fixed in cylindrical shell 1 chamber by big flange circle 4, little flange circle 5, and big flange circle 4, little flange circle 5 are axially vertical with cylindrical shell 1, is connected by stay pipe 6 between flange circle 4 and cylindrical shell 1 internal face greatly.
Above-described lifting blade 2 highly is 1/4 of cylindrical shell 1 radius, and the back side has reinforcement 3 to be connected with the internal face of cylindrical shell 1; Described lifting blade 2 tops make progress the bending angle be 130 the degree.Described delivery sheet 8 is arranged a circle in the cylindrical shell 1 inboard porch that material enters raising material unit, and length is no more than 1 meter, and height and quantity equate that with lifting blade 2 end points to direction of rotation, and the other end and lifting blade 2 connect into one 25 degree angle; Described reclaiming plate 9 is installed in cylindrical shell 1 inboard exit and arranges a circle, and length is no more than 0.6 meter, quantity and equate that with lifting blade 2 other end and lifting blade 2 connect into one 15 degree angle.Described stock guide 7 quantity are 1/2 of lifting blades 2, width is 1/3 of cylindrical shell 1 radius, with cylindrical shell 1 diameter a low-angle being arranged is 15 degree, the bending at described stock guide 7 two ends, the bending angle all is 150 °, direction is opposite, and bending point is respectively on the middle path position of big flange circle 4, little flange circle 5.Stay pipe 6 diameters of the big flange circle 4 of described connection and cylindrical shell 1 internal face are greater than the thickness of big flange circle 4, slotting with big flange circle 4 junctions, be used for wedging big flange circle 4,6 every group of stay pipe 6 quantity, be fixed on the cylinder inboard wall by branch directions such as circumference, form a rigid unitary with big flange circle 4.
When the oven dry before blue charcoal material from dryer high-end enter cylindrical shell 1 after, along with the inclination of cylindrical shell 1 is rotated, feedboard 8 is sent material into lifting blade 2, lifting blade 2 rises to certain angle with material, raise to stock guide 7 directions that are arranged in cylindrical shell 1 chamber, after connecting material, stock guide 7 again material is promoted, space to little flange circle 5 interior diameters raises, material moves constantly raising in the process to dry gradually simultaneously to the reclaiming plate 9 of cylindrical shell 1 low side with the heat air heat exchange, derive material by reclaiming plate 9, finish the oven dry overall process.
The invention has the beneficial effects as follows, in the process of drying machine drying material, what this raising material unit had changed material raises direction, reduce material and raised the drop height degree, the collision that reaches between material and the equipment between the material is slowed down greatly, be conducive to transmit equably heat again and advance material, the breakage rate of drying materials process can be reduced to below 13.4%, realize energy saving purposes.This apparatus structure is simple, is convenient to the maintenance personal and enters maintenance and cleaning, applicable to the rotation straight barrel type dryer of the coke that needs to reduce the oven dry breakage rate equally, slag, flyash, bentonite, desulfurated plaster etc.
