Abstract
The utility model relates to a moulded coal furnace for light firing magnesium, which belongs to a sintering furnace for magnesium ore. Moulded coal chambers are arranged on two lateral parts in a furnace body in a shape like the Chinese character 'tu ', and hot gathering plates are arranged on the upper part of moulded coal in the moulded coal chambers. Fire inlet holes are arranged on a firebrick wall by which the moulded coal chambers and a combustion chamber are separated, a stuff chamber is composed of an arch-shaped furnace plate of the upper part of the combustion chamber and the upper part of the furnace body, and an inverse trapezoidal slide plate which is extended to a discharge port is arranged on the side wall of the middle lower part in the combustion chamber. The utility model has the advantages that the moulded coal is used as fuel; a chimney is cancelled, and 50% of heat efficiency can be improved; the surrounding environment is altered, environmental pollution is reduced, workmen's labor intensity is lightened, and the productivity of the light firing magnesium and the quality of the light firing magnesium are enhanced.
Description
The utility model belongs to the sintering furnace of magnesium ore.
Magnesium ore is to obtain magnesia unslacked magnesium by sintering furnace, and this reverberatory furnace is to loose by two to burn between storing of the common heating of stove, and the magnesium ore between storing is carried out sintering.Its stove is to heating between storing, and needing the smokestack by long about 30 meters is that 5 grades dense smoke is discharged in the atmosphere with Lin Geman.And used high-grade fuel coal combustion is insufficient, and thermal efficiency loss is big, and dense smoke is discharged into contaminated environment in the atmosphere.In the reverberatory furnace combustion process, need continuous coal, increased working strength of workers.
Order of the present utility model provides a kind of labor strength that alleviates, and reduces environmental pollution, and the magnesium ore of energy savings burns stove.
The purpose of this utility model is achieved in that it is made of body of heater, combustion chamber, material chamber and moulded coal chamber etc.Interior two following sides of convex shape body of heater that it is characterized in that refractory brick (8) outsourcing heat-insulation layer (7) are provided with moulded coal chamber (12), and heat collector panel (11) is put on the interior moulded coal in moulded coal chamber (12) (13) top; Have into fire hole (9) on refractory brick (8) wall that moulded coal chamber (12) and combustion chamber (6) are separated by, the arch stove plate (5) on top, combustion chamber (6) constitutes material chamber (4) with upper of furnace body, and middle and lower part, combustion chamber (6) side-walls is provided with down trapezoidal slide plate (10) to discharging opening (15).
The utility model has the advantages that: with the moulded coal is fuel, and having cancelled chimney, can to improve the thermal efficiency about 50%, changed surrounding environment, reduced environmental pollution, alleviates working strength of workers, improved the productivity ratio and the quality of magnesia unslacked.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 puts (side view that removes lower case and refractory brick among Fig. 1) schematic diagram for the indoor moulded coal of moulded coal of the present utility model.
Fig. 3 is a stove plate structure schematic diagram of the present utility model.
Fig. 4 is the heat collector panel structural representation that put on the utility model moulded coal top.
The middle part, top has exhaust outlet (1) on the convex shape body of heater of the present utility model, and sidepiece has charging aperture (2); At the outer cover (3) of body of heater outermost layer for coating heat-insulation layer (7).Gap in the body of heater between the last 10 blocks of battens of arch stove plate (5) at middle part is 50mm, and the fire hole that advances that is had on refractory brick (8) wall that moulded coal chamber (12) and combustion chamber (6) are separated by respectively is 4.Moulded coal body effective dimensions in the body of heater in the moulded coal chamber (12) of two following sides is 800 * 600 * 500 * 4, amounts to 960 moulded coals, incendivity 12 hours.The moulded coal of lighting is to enter the combustion chamber through the enterprising fire hole of heat collector panel (11) crater and furnace wall (9), and temperature can reach 1000 ℃, is the magnesium ore powder through the pyrolysis of being heated of 2 hours magnesium ores of heating.Mineral powder is to fall in the mine car (16) through slide plate (10) and discharging opening (15) by stove plate (5) gap.Among the figure 14 is angle bar.But body of heater integrated stand dress, bottom are reserved turnover dumper position and are got final product.
