Abstract
The invention discloses a circular V-shaped spreading grader which comprises spreading and grading devices, a scattering cone, a guide device and an air baffle. Each spreading and grading device comprises two side boards, a spreading board, a grading board and a slide board. The spreading boards and the grading boards are arranged into two rows from top to bottom. The spreading boards and the grading boards in each row are disposed between the side boards respectively. A gap is reserved between the spreading boards and the grading boards in each row forms a powder passage. The side boards are located below the lowermost grading boards and are disposed between the side boards. The bottom periphery of the scattering cone is sequentially connected with the uppermost spreading boards of the spreading and grading device, and the uppermost grading boards of the spreading and grading device are distributed on the whole bottom periphery of the scattering cone. The air baffle is in an isosceles triangle structure with isosceles sides arranged on the side boards of the adjacent spreading and grading devices. The guide device is composed of V-shaped guide boards as many as the spreading and grading devices. Lateral lower edges of the V-shaped guide boards are arranged at the upper edges of the side boards of the adjacent spreading and grading devices respectively.
Description
Technical field
The present invention relates to a kind of powder tower drier, especially a kind of ring-type V-arrangement of powder tower drier is beaten and is spread grading plant.
Background technology
Existing a kind of powder tower drier comprises cylindrical shell, feed pipe, multicomponent castor bean cone and lubricating substance comb basin, reclaiming cone, exhaust duct, air inlet.Feed pipe and exhaust duct all are arranged on the top of cylindrical shell, and inner barrel is provided with multicomponent castor bean cone and lubricating substance comb basin from top to down, and the bottom of cylindrical shell is provided with reclaiming cone, and the below of reclaiming cone is provided with discharge nozzle, and the bottom of cylindrical shell is provided with air inlet.During work, material enters in the cylindrical shell from feed pipe, high-temperature hot-air is the bottom in air inlet enters cylindrical shell, pass through multicomponent castor bean cone and lubricating substance comb basin from bottom to top, make by the drying materials on sub-material comb basin and the sliding castor bean cone, discharged by exhaust duct then, the material of being dried falls in the reclaiming cone, discharges through discharge nozzle again.After powder material enters cylindrical shell from feed pipe, because the decentralization of material in cylindrical shell is relatively poor, therefore exist it not have the phenomenon of oven dry for the powder material of failing to disperse.Owing to fail the powder material of oven dry and the powder material of not dried are separated, therefore prior art is in order thoroughly to dry above-mentioned powder material, often by lifting means material is reentered in the cylindrical shell and dry, so not only drying efficiency is low, and the energy consumption height.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of ring-type V-arrangement and beats and spread grading plant, and this device can be separated the powder material of oven dry and the powder material of not dried, thus favourable raising drying efficiency not only, and also energy consumption is low.
For solving the problems of the technologies described above, a kind of ring-type V-arrangement of the present invention is beaten and is spread grading plant, be used for the powder tower drier, contain to beat and spread clasfficiator, material spreading cone, material guide device and deep bead, beat and to spread clasfficiator and contain biside plate, beat and spread plate, graded plate and sliding plate, beat and to spread plate and graded plate respectively forms a line from top to down, beating of respectively forming a line spreads plate and graded plate is separately positioned between the biside plate, beating of respectively forming a line spread and left spacing between plate and the graded plate and formed the powder passage, beat and to spread angulation between plate and the graded plate, sliding plate is below bottom graded plate and be arranged between the biside plate; Spreading clasfficiator beating topmost with several dozens successively on the periphery of described material spreading cone lower end spreads plate and links to each other, and several dozens are spread the periphery that clasfficiator graded plate topmost is covered with described material spreading cone lower end, deep bead is isosceles triangular structure, two isosceles limits of deep bead are separately positioned on adjacent beating on the side plate that spreads clasfficiator, material guide device is spread the identical V-arrangement stock guide of clasfficiator quantity and constitutes with beating by quantity, and the bottom of V-arrangement stock guide both sides is separately positioned on adjacent beating on the limit, upper end of spreading the clasfficiator side plate.
Described beat spread clasfficiator form a line from top to down beat and spread its bottom of plate and beat and spread a hinged air door on the plate.
Describedly beat that to spread the angle that forms between plate and the graded plate be 65 ° to 75 °.
The described angle that spreads clasfficiator and vertical direction of beating is 12 ° to 5 °.
Above-mentioned ring-type V-arrangement is beaten when spreading the grading plant use, powder material drops to beat from material spreading cone and spreads the clasfficiator, by beating in the process of spreading clasfficiator, the thermal current that powder material is not only passed through once and again dispels, and spread constantly bump repeatedly of plate and graded plate with beating, and carry out heat exchange with thermal current, in the process of passing through the powder passage, fine grained by graded region, falls into the finished product awl of peripheral hardware with thermal current at last; And the not powder material of oven dry of poor dispersion, then can not be taken away by thermal current, fall by sliding plate, continue to carry out heat exchange with thermal current, spread in the clasfficiator and pass through graded region if bring into to beat by the powder material of being dried then by thermal current, if the powder material of not dried falls into the reclaiming cone of powder vertical drying machine drum body lower end at last, thereby the powder material to the powder material of oven dry and not oven dry carries out classification, at last by the lifting means said process that circulates again, dried until powder material, so just having overcome prior art can not be with the powder material of oven dry and the deficiency that is separated of the powder material that not have to dry, therefore not only be conducive to improve drying efficiency, and energy consumption is low.
