Abstract

The utility model relates to a combined energy saving furnace used in an aluminium electrolyzing preroasting anode calcining furnace, characterized in that, an upper cover and a base are both made of fire-resisting materials, the upper cover is provided with an inspection hole with a closing cap, therefore, the upper cover is not required to open when observing the conditions in the furnace, only the closing cap is opened, causing operation to be handy and agile. A flare manhole is arranged on a base of the furnace, the structure adopted by the upper cover is matched with the flare part of the base manhole, causing tight close when the upper cover is covered on the base. The upper cover of the utility model is provided with the inspection hole, thereby greatly reducing working load of the workers in the producing operation. In addition, because the fire-resisting material has good heat shielding performance and thermal shock resistance, causing the furnace to have less heat loss, reducing consumption of the heavy oil, reducing energy source waste, reducing temperature in workshops, improving working environment of the workers, meanwhile prolonging service life of the furnace, greatly reducing production cost, increasing producing efficiency.

Description

The combined type energy-saving stove and accessory

One, technical field

The utility model relates to a kind of aluminum electrolysis prebake anode roasting that is applicable to and burns the combined type energy-saving stove and accessory that stove uses.

Two, background technology

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, aluminum electrolysis prebake anode roasting burns stove 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.The effect of its stove and accessory is to be convenient to install roasting apparatus and to observe situation in the stove.Yet the situation that existing stove and accessory is to use roasting apparatus still to observe in the stove all needs the loam cake of stove and accessory is opened.The stove and accessory of roaster use at present is a cast iron quality, 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, causes 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

The purpose of this utility model provides a kind of combined type energy-saving stove and accessory of making of refractory material, and stove and accessory heaviness, anti-thermal shock ability, heat loss that cast iron stove and accessory that aluminum current electrolysis prebaked anode roaster furnace uses exists are big to solve, waste astatki and cause deficiencies such as working environment high temperature, high heat.

The combined type energy-saving stove and accessory is covered on the stove and accessory base by the stove and accessory loam cake to be formed.Characteristics of the present utility model are that the loam cake and the base of stove and accessory all adopts refractory material to make, on stove and accessory, cover the peep hole that is provided with the band capping, like this, in observing stove, need not loam cake is raised during situation, only need open capping and get final product, make operation become light and handy, flexible.See inspecting hole for enlarging on the base of this stove and accessory, enlarging place that structure that its loam cake adopts and base are seen inspecting hole is complementary, and can accomplish tight joint close with enlarging place of seeing inspecting hole of base when making loam cake cover on base.

Upper cover design of the present utility model has peep hole, greatly reduces working strength of workers in production operation.In addition, because of refractory material has good heat-proof quality and thermal shock resistance, make this stove and accessory reduce heat-energy losses, reduce heavy oil consumption, reduced energy waste, also reduced the temperature in the factory building, improved workman's working environment, also prolong simultaneously the service life of stove and accessory, reduced production cost significantly, improved production efficiency.

Four, description of drawings

Fig. 1 is the structural representation of the stove and accessory that uses in the background technology; 1 is loam cake among the figure, and 2 is base.

Fig. 2 is a decomposition texture schematic diagram of the present utility model; 1 is loam cake among the figure, and 2 is base, and 3 is peep hole, and 4 are capping, and 5 is guard ring.

Five, the specific embodiment

As shown in Figure 2, the utility model is made up of stove and accessory loam cake 1 and base 2, loam cake 1 and base 2 are disc-shaped structure, the employing refractory material is made, to compare heat-proof quality good with the cast iron stove and accessory, and have good anti-seismic performance, make this stove and accessory in the replacement process of regular high temperature and low temperature, be difficult for producing bursting.For situation in the convenient observation stove, on stove and accessory loam cake 1, have peep hole 3, cover on peep hole 3 with arc capping 4 at ordinary times, available iron chains links to each other capping 4 with anti-lost with loam cake 1.When needing to observe the situation in the roaster capping 4 is opened and can be observed, need not to open loam cake 1, and just need when only installing and using roasting apparatus loam cake 1 is opened, make like this workman in production operation more lightly, freely, and can reduce scattering and disappearing of heat to a great extent.The inspecting hole top of seeing on the base 2 is the shape of outside enlarging, loam cake 1 is a gag shape structure, its gag shape should be complementary with enlarging place of seeing inspecting hole of base 2 (promptly matching), make loam cake 1 cover base 2 see on the inspecting hole time more tight, outwards dispel the heat to stop stove and accessory.More sturdy and durable for the stove and accessory loam cake 1 that refractory material is made, be installed with irony guard ring 5 at the periphery of the loam cake 1 of this stove and accessory, so just can prolong the service life of this stove and accessory greatly.

Claims (3)

1, a kind of combined type energy-saving stove and accessory is covered on band is seen the base of inspecting hole by the stove and accessory loam cake and to form; It is characterized in that: loam cake of this stove and accessory (1) and base (2) all adopt refractory material to make, and cover the peep hole (3) that is provided with band capping (4) on this stove and accessory.

2, combined type energy-saving stove and accessory according to claim 1 is characterized in that: the base of this stove and accessory (2) is gone up to enlarging and is seen inspecting hole, and enlarging place that structure that its loam cake (1) adopts and base are seen inspecting hole is complementary.
