Description
Technical field
The utility model relates to a kind of closed smelting furnace.
Background technology
Smelting furnace is mainly used in casting of metals and produces, be illustrated in figure 1 the closed smelting furnace of prior art, 1 ' is body of heater, and 2 ' is Inner stove, and 3 ' is bell, described body of heater 1 ' is individual layer body of heater, so heat losses is very serious in fusion process, and bell 3 ' directly covers on body of heater 1 ', when melting, be easy between body of heater 1 ' and bell 3 ' produce gap and make to cover imprecision, affect Smelting Effect.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of Smelting Effect good, and the closed smelting furnace of high insulating effect.
The utility model solves the technical scheme that its technical problem adopts: a kind of closed smelting furnace, the Inner stove comprising body of heater, be arranged on the melting chamber in body of heater and be arranged in melting chamber, liner is provided with between described body of heater and melting chamber, vacuum chamber is formed between described liner and inboard wall of furnace body, on described body of heater, correspondence is provided with bell, be lining with in described bell lid is located at, the level height of described bell is equal with the level height of body of heater, and the diameter of bell is greater than the diameter in melting chamber and the diameter of bell is less than the diameter of liner.
In order to carry out spacing to bell, above described bell, both sides are equipped with limited block, and described limited block one end fixes on liner top by hinges fixing.
In order to increase the firm intensity of body of heater upper port, described body of heater top outer is provided with reinforcing ring, and the height of described reinforcing ring is slightly larger than the thickness of bell.
The beneficial effects of the utility model are: this closed smelting furnace adds liner between body of heater and Inner stove, make to form vacuum chamber between liner and inboard wall of furnace body, improve heat insulation effect, decrease heat losses, bell adopts embedded design, and limited block is added on bell, bell can be had and be closely combined with body of heater, improve Smelting Effect.

In figure: 1. body of heater, 2. Inner stove, 3. bell, 4. liner, 5. limited block, 6. reinforcing ring, 7. melting chamber, 8. vacuum chamber.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 2 and 3, a kind of closed smelting furnace, the Inner stove 2 comprising body of heater 1, be arranged on the melting chamber 7 in body of heater 1 and be arranged in melting chamber 7, liner 4 is provided with between described body of heater 1 and melting chamber 7, vacuum chamber 8 is formed between described liner 4 and body of heater 1 inwall, on described body of heater 1, correspondence is provided with bell 3, described bell 3 lid is located on liner 4, the level height of described bell 3 is equal with the level height of body of heater 1, and the diameter of bell 3 is greater than the diameter in melting chamber 7 and the diameter of bell 3 is less than the diameter of liner 4.
In order to carry out spacing to bell 3, above described bell 3, both sides are equipped with limited block 5, and described limited block 5 one end fixes on liner 4 top by hinges fixing.
In order to increase the firm intensity of body of heater 1 upper port, described body of heater 1 top outer is provided with reinforcing ring 6, and the height of described reinforcing ring 6 is slightly larger than the thickness of bell 3.
In fact, bell 3 is connected for embedded with liner 4, and bell 3 is embedded into the port of liner 4.
Compared with prior art, this closed smelting furnace adds liner 4 between body of heater 1 and Inner stove 2, make to form vacuum chamber 8 between liner 4 and body of heater 1 inwall, improve heat insulation effect, decrease heat losses, bell 3 adopts embedded design, and adds limited block 5 on bell 3, bell 3 can be had closely be combined with body of heater 1, improve Smelting Effect.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
