Abstract
The utility model provides a vertical sintering furnace which comprises a hearth, wherein combustion chambers are arranged on the two sides of the hearth and are connected with the hearth through fire tubes, a discharging vibration disc is arranged on the bottom of the hearth, a stock column is arranged inside the hearth, and three layers of fire grate type drying beds are arranged above the stock column in the hearth. Due to the adoption of the three layers of fire grate type drying beds, for a pellet high in water content, physical water is removed from the fresh pallet on the upper layer of drying bed and on the middle layer of drying bed, crystal water is removed from the fresh pallet on the bottom layer of drying bed, the quality of a dry pallet is improved, deformation and mutual bonding of wet pallets which are placed into the furnace are avoided, air permeability of a material layer in the furnace is improved, and conditions for smooth motion of furnace charges are created.
Description
technical field:
The utility model relates to a kind of sintering furnace, is specifically related to a kind of vertical sintering furnace.
background technology:
Vertical sintering furnace is a kind of according to the heat-exchange apparatus of counterflow principle work, be characterized in green-ball being packed in stove by apparatus for distributing at furnace roof, green-ball declines continuously with uniform speed, the hot gas of combustion chamber enters in stove from bocca, and hot gas carries out heat exchange with top-down green-ball from bottom to top.Green-ball enters roast area through drying and preheating, in roast area, carry out high-temperature concretion reaction, then in lower furnace, carry out cooling and discharge, whole process is once to complete in vertical sintering furnace, hence one can see that, and the most important prerequisite of vertical sintering furnace normal operating is that furnace charge should have good gas permeability, in order to guarantee this point, the essential loose cloth equably of green-ball is to stock column.
Conventional vertical sintering furnace adopts rectangle cloth at present, and stockline is pressed close to furnace wall automatic distributing, and charge level is " V " type deeply, and center is low, high near place, furnace wall, and the longitudinal centre line that this cloth forms temperature does not around reach the needed desirable sintering temperature of pellet.
summary of the invention:
The purpose of this utility model is to provide a kind of vertical sintering furnace for the problem of above-mentioned existence, adopt the dry green-ball of drying bed, improved dry bulb quality, prevented wet bulb enter distortion that stove produces and and the phenomenon that is bonded to each other, improved the gas permeability of the bed of material in stove, for burden direct motion has been created condition.
Above-mentioned object realizes by following technical scheme:
Vertical sintering furnace, comprise burner hearth, described burner hearth both sides are provided with combustion chamber, described combustion chamber connects described burner hearth by fire tube, described burner hearth bottom is provided with discharge vibrating disk, described burner hearth the inside is provided with stock column, and described burner hearth the inside is positioned at described stock column top and is provided with three layers of grate drying bed.
Described vertical sintering furnace, three layers of described fire grate drying bed comprise superposed herringbone drying bed, described herringbone drying bed bottom is provided with perpendicular intermediate layer drying bed, and described drying bed bottom, intermediate layer is provided with the bottom drying bed vertical with intermediate layer drying bed.
Described vertical sintering furnace, described burner hearth inner width is not more than 2 meters.
Beneficial effect:
1. the utility model adopts three layers of grate formula drying bed, for the larger pelletizing of water content, green-ball removes mechanical water on upper strata drying bed and intermediate layer drying bed, on bottom drying bed, remove the crystallization water, improved dry bulb quality, prevented that wet bulb from entering the distortion of stove generation and the phenomenon being bonded to each other, improved the gas permeability of the bed of material in stove, for burden direct motion has been created condition, adopt in addition drying bed, expanded drying area, can accomplish that the thin bed of material is dry, hot gas evenly penetrates the green-ball bed of material, has improved efficiency of utilization.
If 2. vertical sintering furnace width is excessive, because producing resistance to air-flow, pelletizing causes edge effect, a little less than making vertical sintering furnace central gas stream, stove center easily forms " dead stock column ", therefore the inner width of vertical sintering furnace of the present utility model is not more than 2 meters, guarantees the gas permeability at stove center.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure 1, burner hearth; 2, combustion chamber; 3, fire tube; 4, discharge vibrating disk; 5, stock column; 6, herringbone drying bed; 7, intermediate layer drying bed; 8, bottom drying bed.
the specific embodiment:
Embodiment 1:
As shown in Figure 1: vertical sintering furnace of the present utility model, comprise burner hearth 1, described burner hearth both sides are provided with combustion chamber 2, described combustion chamber connects described burner hearth by fire tube 3, described burner hearth bottom is provided with discharge vibrating disk 4, described burner hearth the inside is provided with stock column 5, and described burner hearth the inside is positioned at described stock column top and is provided with three layers of grate drying bed.
Embodiment 2:
Vertical sintering furnace described in embodiment 1, three layers of described fire grate drying bed comprise superposed herringbone drying bed 6, described herringbone drying bed bottom is provided with perpendicular intermediate layer drying bed 7, and described drying bed bottom, intermediate layer is provided with the bottom drying bed 8 vertical with intermediate layer drying bed.
Embodiment 3:
Vertical sintering furnace described in embodiment 1 or embodiment 2, described burner hearth inner width is not more than 2 meters.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
Claims (3)
