Abstract

The utility model discloses a roasting furnace complex stove used on an aluminum electrolytic pre-roasting anode roasting furnace, which includes an upper cover and a base with an annular structure. The upper cover and the base of the utility model adopt refractory materials, a guard ring is arranged on the inner side at the lower part of a round hole on the base, the upper part of the round hole on the base is shaped like a circular truncated cone enlarging upwards, and a circle of concave should is arranged on the upper edge of the round hole. The shape of the upper cover is adapted to that of the upper part of the round hole on the base. The utility model adopts a design of variable diameter, thereby reducing the inner diameter of the stove, reducing the cooling surface, and further strengthening the effect of energy conservation. The consumption of heavy oil is reduced, and the waste of energy is reduced. The environmental temperature of a workshop is reduced, and the working environment of workers is improved. The service life of the stove is prolonged, and the cost is greatly reduced. The stove is flexible and easy to use, and the intensity of labor is reduced.

Description

The compound stove and accessory of roaster

One, technical field

The utility model relates to a kind of aluminum electrolysis prebake anode roasting and burns the stove and accessory that uses on the stove.

Two, background technology

In Aluminium Electrolysis, roasting is one of important step in the aluminium anode production process, and roaster is the capital equipment of anode-baking, adopts the heavy oil combustion heating.Produce needs in order to satisfy, roaster will use a large amount of stove and accessorys.Concrete usage quantity is determined according to furnace chamber quantity and quirk quantity.General every quirk need use stove and accessory 4 covers, and for example the roaster of Room 34 9 quirks just needs to use stove and accessory 1260 covers.Stove and accessory comprises annular base and discoidal loam cake, and all grooves are arranged on the annular base, on be stamped downward edge of a week, can be inserted in the groove of base.The effect of stove and accessory is to be convenient to install roasting apparatus and to observe situation in the stove, and being to use roasting apparatus still to observe the interior situation of stove is all to need loam cake is opened.The stove and accessory that uses is a cast iron quality now, uses through reality and finds that its defective is bigger:

1, because cast iron has thermal conductivity preferably, the stove and accessory heat radiation is very fast, makes the roaster heat loss big, too much consumes heavy oil.Cause energy waste.Cause simultaneously temperature rising in the factory building again, worsened the working environment of workers.

2, the thermal shock resistance of cast iron is bad, is easy to burst in regular high temperature and low temperature exchange process.

3, cast iron stove and accessory weight is bigger, uses heavy.The operator needs the situation in the stove of often observing in process of production, at this moment just need the stove and accessory loam cake is opened, and each action need is opened more than 15 continuously.Because stove and accessory is comparatively heavy, has increased labour intensity to the workman in actual production process.

Three, summary of the invention

Order of the present utility model provides the compound stove and accessory of a kind of roaster, reduces the stove and accessory area of dissipation, reduces the thermal conductivity of stove and accessory, reduces energy waste; Strengthen the thermal shock resistance of stove and accessory.

The technical solution adopted in the utility model is: the compound stove and accessory of roaster comprises loam cake and base, its base is a loop configuration, loam cake of the present utility model and base adopt refractory material to make, add guard ring in base circular hole lower inside, the circular hole top of base is the truncated conical shape that upwards enlarges, and all recessed shoulders are arranged in the upper edge of this circular hole.The shape of loam cake and base circular hole shaped upper part adapt.

The utility model adopts the reducing type design, makes in the stove and accessory through dwindling, and reduces area of dissipation, has further strengthened energy-saving effect.Loam cake cooperates with base closely, and the loam cake periphery drops in the recessed shoulder on base circular hole top.The following advantage of contrast prior art tool:

1, reduces heavy oil consumption, reduce energy waste.

2, reduce the power house environment temperature, improve workman's working environment.

3, prolong the service life of stove and accessory, reduce cost significantly.

4, stove and accessory is in use easy-to-use flexibly; Reduce working strength of workers.

Four, description of drawings

Fig. 1 is the structural representation of existing stove and accessory loam cake and base;

Fig. 2 is the decomposition texture schematic diagram of the utility model loam cake and base.

Five, the specific embodiment

The utility model adopts refractory material to make the loam cake 1 and base 2 of stove and accessory, and refractory material has good heat-proof quality and heat-insulating property, scatters and disappears thereby reduce heat.Refractory material also has good thermal shock resistance, is not easy to produce in regular high temperature and low temperature replacement process to burst.Add irony guard ring 7 in base 2 circular hole lower inside, this structure had both increased the intensity of base, made the stove and accessory dismounting simple again.One week of outer at loam cake 1 is installed irony guard ring 3, and the intensity of bell is increased greatly.Leave slit 8 between guard ring 7 and the base 2, this slit 8 usefulness asbestos cords filling is to reduce expansion and to strengthen shockproof.Be provided with open-work 4 as peep hole on loam cake 1, tegillum 5 is installed on open-work 4, tegillum 5 is the arc that is upturned all around, and is connected to loam cake 1 with anti-lost with iron chains 6.Need not loam cake 1 is raised when observing in the stove situation, only need open peep hole tegillum 5 and get final product, make to operate to become light and handy.

Claims (5)
