Abstract

A kind of large-scale aluminum carbon anode roasting furnace of more hoppers, including heating quirk and roasting hopper are the utility model is related to, heating quirk inner chamber is provided with vertical quirk partition wall, and the quantity of described roasting hopper is 13, and the quantity of vertical quirk partition wall is 5.The beneficial effects of the utility model are：1st, using Novel roasting furnace structure, the shove charge plot ratio of hopper had so both been ensured, and had improved production capacity, and fuel and fugitive constituent is fully burnt in heating quirk again, reduce energy consumption.2nd, hopper quantity increases to 13 by 89, and hopper size is by original 4580 × 780 × 4950（Length × width × height）Change to 6100 × 850 × 6100（Length × width × height）, Installed furnace volume improves 16.7%；Quirk widens 50mm, reduces the hot gas flow velocity inside quirk using " WV " type, fuel and fugitive constituent is burnt as much as possible in quirk, reach energy-saving purpose.

Description

More large-scale aluminum carbon anode roasting furnaces of hopper

Technical field

It the utility model is related to a kind of anode-baking furnace, more particularly to a kind of large-scale aluminum carbon anode roasting furnace of more hoppers.

Background technology

Anode-baking furnace is the key equipment for producing aluminum carbon anode, and the heating energy source of roaster is by external heat source and itself Heat storage forms.Thermal source mainly includes：The extraneous fuel, interiors of products major part asphalt volatile constituents and filling for introducing roaster are burnt Scaling loss, specific energy consumption be weigh production cost important evidence.Specific energy consumption depend on roaster charging box plot ratio and The abundant burning of fuel, the furnace type structure of old-fashioned roaster can not meet the needs of current industrialized production development, more hoppers Aluminum carbon anode roasting furnace brickwork new technology, solve the production problem for restricting development, be calcined furnace structure by changing, reach and carry High production capacity reduces the purpose of energy consumption.

Utility model content

Technical problem to be solved in the utility model is：A kind of large-scale aluminum carbon anode roasting furnace of more hoppers is provided, used Handled in the high-temperature roasting of aluminum carbon anode product, by increasing hopper quantity, increase hopper size, changing quirk sectional area etc. Measure, on the basis of production capacity is improved, combustible is fully burnt in heating quirk as far as possible, reduce specific energy consumption, save Production cost.

The utility model is to solve the problems, such as that used technical scheme set forth above is：

A kind of large-scale aluminum carbon anode roasting furnace of more hoppers, including heating quirk 1 and roasting hopper 2, heating quirk 1 inner chamber Vertical quirk partition wall 3 is provided with, the quantity of described roasting hopper 2 is 13, and the quantity of vertical quirk partition wall 3 is 5.

The described length of roasting hopper 2 is 6100 mm, and width is 850 mm, is highly 6100 mm.

The described width of heating quirk 1 is 520 mm.

The beneficial effects of the utility model are：1st, using Novel roasting furnace structure, so both ensured that the shove charge of hopper was held Product rate, improves production capacity, fuel and fugitive constituent is fully burnt in heating quirk again, reduces energy consumption.2nd, anode-baking furnace Mostly 8-9 hoppers, about 5 meters or so of length, flame path structure are mostly " W " type, and such a structure has fire path temperature skewness, temperature The problems such as dead angle is more, and gas flow resistance is larger, more large-scale aluminum carbon anode roasting furnace new technologies of hopper, to hopper quantity, Hopper size, the structure of quirk are improved, and hopper quantity increases to 13 by 8-9, hopper size by original 4580 × 780×4950（Length × width × height）Change to 6100 × 850 × 6100（Length × width × height）, Installed furnace volume improves 16.7%；Quirk is widened 50mm, the hot gas flow velocity inside quirk is reduced using " WV " type, fuel and fugitive constituent is burnt as much as possible in quirk, Energy consumption is reduced to 50 cubes/ton by original cube/ton of air consumption 70, and it is vertical can be reduced to 40 for unit consumption if technological operation is good Side/ton, fuel 28.6% is saved, reaches energy-saving purpose.

Brief description of the drawings

Fig. 1 is the floor plan of conventional anode roaster；

Fig. 2 is Section A-A schematic diagram in Fig. 1；

Fig. 3 is elevational schematic view of the present utility model；

Fig. 4 is section B-B schematic diagram in Fig. 3.

Wherein, 1- heats quirk, 2- roasting hoppers, the vertical quirk partition walls of 3-.

Embodiment

Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.

Reference picture 1-4, a kind of more large-scale aluminum carbon anode roasting furnaces of hopper described in present embodiment, including heating Quirk 1 and roasting hopper 2, heating quirk 1 inner chamber are provided with vertical quirk partition wall 3, and the quantity of described roasting hopper 2 is 13 Individual, the quantity of vertical quirk partition wall 3 is 5.

The described width of heating quirk 1 is 520 mm.

The beneficial effect of present embodiment is：1st, using Novel roasting furnace structure, the dress of hopper had so both been ensured Furnace volume rate, improves production capacity, fuel and fugitive constituent is fully burnt in heating quirk again, reduces energy consumption.2nd, anode roasts It is mostly 8-9 hoppers to burn stove, about 5 meters or so of length, and flame path structure is mostly " W " type, such a structure exist fire path temperature skewness, The problems such as temperature dead angle is more, and gas flow resistance is larger, more large-scale aluminum carbon anode roasting furnace new technologies of hopper, to hopper number Amount, hopper size, the structure of quirk are improved, and hopper quantity increases to 13 by 8-9, and hopper size is by original 4580 ×780×4950（Length × width × height）Change to 6100 × 850 × 6100（Length × width × height）, Installed furnace volume improves 16.7%；Quirk adds Wide 50mm, the hot gas flow velocity inside quirk is reduced using " WV " type, fuel and fugitive constituent is fired as much as possible in quirk Burn, energy consumption is reduced to 50 cubes/ton by original cube/ton of air consumption 70, and unit consumption can be reduced to if technological operation is good 40 cubes/ton, fuel 28.6% is saved, reaches energy-saving purpose.

Specific embodiment of the utility model is not formed to limitation of the present utility model, every to use phase of the present utility model Like structure and change, in the scope of protection of the utility model.
