Description
Technical field
The utility model relates to a kind of carbon baking furnace, is specially a kind of box carbon baking furnace that adopts the direct heating muff of flame.
Background technology
Present roaster comprises bottom a heatable brick bed body and top quirk wall and product box composition, described quirk wall two ends are provided with combustion heating chamber, surround a quirk in the middle of the quirk wall, heat is delivered in the product box by quirk in the combustion heating chamber, be transmitted on the heated goods by the inserts in the product box then, adopt the roaster product programming rate of this kind structure slow, the roasting temperature of finally banking up a fire can only reach 900 ℃, the temperature of finally banking up a fire is low, the cycle of the big specification product of roasting 780mm～920mm reaches 37～42 days, firing cycle is long, and electrode both sides and upper and lower temperature difference reach 20～30 ℃ in the furnace chamber, and the temperature difference is big in the furnace chamber.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of roaster that the temperature difference obviously reduces, effectively improves the temperature of finally banking up a fire, shortens the firing cycle energy savings, improves the quality of products in the furnace chamber that makes.
The utility model adopts following technical scheme:
Product box that the utility model comprises a heatable brick bed body that is arranged on the body of heater bottom, be arranged on quirk wall on a heatable brick bed body, separated by the quirk wall and the combustion heating chamber that is arranged on the product box two ends, the product box two ends are by advancing burner and combustion heating chamber is connected, the product box lower end be provided with a heatable brick bed body in the crater that is connected of a heatable brick bed body flue.
A heatable brick bed body described in the utility model is divided into two-layer up and down, and it comprises first floor a heatable brick bed preheating road and bottom a heatable brick bed preheating road, and crater is connected by first floor a heatable brick bed preheating road, bottom a heatable brick bed preheating road and a heatable brick bed body flue.
The utility model is provided with interlayer heating quirk in quirk wall bottom, its upper end is connected by crater and product box, and the lower end is connected by returning burner, first floor a heatable brick bed preheating road, bottom a heatable brick bed preheating road and a heatable brick bed body flue.
The good effect of the utility model roaster is as follows:
1. can make the roasting temperature of finally banking up a fire reach 1100 ℃, reduce the resistivity of product.
2. the physical and chemical index of roasting product: 800mm～900mm carbon resistance rod sample, bulk density is 1.586～1.620g/cm
3, resistivity is: 40.2～44.1 μ Ω m are better than the physicochemical property that common roaster burns the electrode that.
3. from heating curve, the big specification product of roasting 780mm～920mm on average heats up at 30 ± 2 ℃ at warming up period, and the volatilization phase on average heats up at 12 ± 2 ℃, is higher than 5 ℃ of common roasters, and coking period on average heats up 18 ℃, is higher than 13 ℃ of common roasters.The big fire phase, the highest intensification per tour reached 60 ℃, had improved heating rate greatly.
4. use this kind roaster, the cycle of the big specification product of roasting 780mm～920mm is 17～19 days, has shortened 20～23 days than the firing cycle of common roaster.
5. the temperature difference of electrode top, bottom and electrode both sides is up to 10 ℃ in the product box, and the temperature difference obviously reduces in the furnace chamber.

Accompanying drawing 2 is the A-A generalized section of accompanying drawing 1
Accompanying drawing 3 is the B-B generalized section of accompanying drawing 1
Accompanying drawing 4 is the C-C generalized section of accompanying drawing 1
In the drawings: 1 combustion heating chamber, 2 product boxes, 3 quirks, 4 a heatable brick bed bodies, 5 first floor a heatable brick bed preheating roads, 6 bottom a heatable brick bed preheating roads, 7 a heatable brick bed body flues, 8 advance burner, 9 craters, 10 return burner, 11 quirk walls.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in drawings, the utility model roaster mainly is made of combustion heating chamber 1, product box 2, quirk wall 11, a heatable brick bed body 4 etc.Be provided with combustion heating chamber 1 at product box 2 two ends, each product box 2 two ends is provided with three over against combustion heating chamber 1 top and advances burner 8, advances the burner 8 wide 200mm～300mm of being, height is 400mm～500mm.Quirk wall 11 bottoms are provided with upper, middle and lower triplex row 14 and list burner 9, in going up two row craters 9 wide be 100mm～130mm, height is 50mm～80mm, bottom delegation crater 9 wide 100mm～130mm, height is 120mm～150mm.Be provided with interlayer heating quirk 3 in quirk wall 11 bottoms, quirk 3 inner bottom parts be provided with 6 lead to a heatable brick bed body return burner 10.Each returns burner 10 wide 230mm～350mm, and length is 450～550mm.Because heat can directly enter heating product in the product box 2 in the combustion heating chamber 1, thereby has increased substantially the thermal efficiency, has shortened firing cycle, reaches the purpose of environmental protection and energy saving.
For strengthening heat insulation effect, a heatable brick bed body 4 of bottom is arranged to double-layer structure up and down, adopts refractory brick to build by laying bricks or stones.Long is 7890mm, and wide is 6990mm.The inner first floor a heatable brick bed of a heatable brick bed body preheating road 5 communicates with bottom a heatable brick bed preheating road 6, is divided into horizontal and vertical both direction, the first floor a heatable brick bed preheating road 5 of mark, the horizontal preheating of 6 representatives road, bottom a heatable brick bed preheating road in the Figure of description 2.Length is 6070mm, and width is 120mm, highly is 544mm.The first floor a heatable brick bed preheating road 5 of mark, the vertical preheating of 6 representatives road, bottom a heatable brick bed preheating road in the Figure of description 3, length is 7198mm, width is 120mm, highly is 544mm.Return the long 6070mm of being in preheating road, burner bottom, wide is 230mm, and height is 544mm.Bottom a heatable brick bed preheating road 6 is connected with a heatable brick bed body flue 7.
Heat of the present utility model trend is: the heat that combustion heating chamber 1 produces enters in the product box 2 through advancing burner 8, enters in the quirk 3 from the crater 9 of quirk wall 11 bottoms, enters in a heatable brick bed body 4 through returning burner 10 then.After first floor a heatable brick bed preheating road 5 in a heatable brick bed body 4 enters bottom a heatable brick bed preheating road 6, enter a heatable brick bed body flue 7 again, after chimney remaining flue gas is discharged, because heat is introduced in the product box, direct heating product reaches and improves the roasting temperature of finally banking up a fire, and shortens the purpose of firing cycle.
