Embodiment

The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.

Built-in accumulation of heat lead stove as shown in Figures 1 to 4, is the utility model optimum embodiment, is melted for heating And aluminium liquid is stored, including holding furnace 1 and two melting furnaces 2.Two melting furnaces 2 can be symmetrically distributed in the end of holding furnace 1.Melting furnace 2 include outer steelframe 5, the body of melting furnace 2 and the aluminum melting burner hearth 6 being arranged in the middle part of the body of melting furnace 2.In order to avoid the aluminium liquid wall built-up of fusing Aluminium liquid proper flow is influenceed, the outer wall of aluminum melting burner hearth 6 is poured by common castable and is made, and inwall then pours system by ball non-sticky to aluminum castable Into.It is surround in order to preferably improve the heat insulation effect of melting furnace 2, between the outer steelframe 5 and the body of melting furnace 2 of melting furnace 2 and is provided with stone Cotton heat-insulation layer 19.The front portion of aluminum melting burner hearth 6 is provided with feeding furnace door 7, and the rear portion of aluminum melting burner hearth 6 is provided with aluminium flowing-out mouth 8, the aluminium flowing-out mouth 8 of melting furnace 2 Connected with the insulation burner hearth 4 of holding furnace 1.

The body ecto-entad of melting furnace 2 is arranged lightweight brick layer 9 and argillic horizon 10 successively, the argillic horizon 10 of the body both sides of melting furnace 2 It is interior it is hollow there is thermal 11, the top of thermal 11 is hollow to be had prechamber 12, internal is filled with heat-storing sphere 13, accumulation of heat The bottom of chamber 11 is covered with gear firebrick 14, offers in the argillic horizon 10 kept off under firebrick 14 and is connected with external blower or air-introduced machine gas circuit Wind and smoke passage 15, the both sides of the body of top melting furnace 2 be respectively symmetrically provided with the natural gas line of outer combustion gas pipeline connection 16, The both sides of top aluminum melting burner hearth 6 correspond to natural gas line 16 and offer quirk 17 respectively.

Holding furnace 1 includes bottom steel frame 3 and is arranged on the insulation burner hearth 4 of the top of bottom steel frame 3.In order to avoid the aluminium of fusing Liquid wall built-up influences aluminium liquid proper flow, and the insulation surrounding of burner hearth 4 is poured with bottom by ball non-sticky to aluminum castable to be made, and top is by commonly pouring Material feeding, which pours, to be made.

The top of insulation burner hearth 4 has upper heat-insulation layer 18, has two symmetrical thermals 11 in the upper heat-insulation layer 18, stores The hot inside of chamber 11 is filled with heat-storing sphere 13, and wind and smoke passage 15, two thermals are respectively symmetrically offered between two thermals 11 11 outsides then symmetrically offer the natural gas line 16 through upper heat-insulation layer 18 and the quirk 17 through insulation burner hearth 4, the day So there is hollow prechamber 12 between feed channel 16 and quirk 17, between the wind and smoke passage 15 and thermal 11, accumulation of heat There is gear firebrick 14 lattice gear between chamber 11 and prechamber 12.Gear firebrick 14 on there are a large amount of spaces, with a large amount of heat-storing spheres 13 it Between the space that is formed, steady flame effect can be effectively played.Further, it is incubated between burner hearth 4 and bottom steel frame 3 and is provided with lower heat-insulation layer 20, lower heat-insulation layer 20 can use light-weight brick arrangement to be built into, and can provide good insulation effect to be incubated the circumference of burner hearth 4 and bottom surface Fruit, further reduce thermal losses.

In production, when air is preheated to more than 1000 DEG C, fuel is i.e. flammable in the case where oxygen concentration is 2% Burn, reach a high temperature air burning principle.Gas-phase space forms the relatively uniform high temperature intense radiation black matrix of a temperature, Heat Transfer in Furnace Efficiency significantly improves.

In actual production, when heat-storing sphere 13 has stored sufficient heat in the side thermal 11 of melting furnace 2, this side thermal Wind and smoke passage 15 under 11 for air channel and connects air blower, and the wind and smoke passage 15 of opposite side then for flue and connects air-introduced machine.It is logical Air blower is crossed to the air blast of thermal 11.Heat exchange is carried out with heat-storing sphere 13 when cold air passes through heat-storing sphere 13, cold air is heated Afterwards to prechamber 12.Now, natural gas is through natural gas line 16 to prechamber 12 and heated cold air mixed combustion, Then enter aluminum melting burner hearth 6 through quirk 17, heating fusing is carried out to the aluminum feedstock in aluminum melting burner hearth 6.Combustion process is by automatically controlled system Conjunction reversal valve under unified central planning uses, and high-temperature flue gas caused by aluminum melting, is then attracted by air-introduced machine, passed through after the thermal 11 of opposite side Flue is discharged.Now, due to being filled with heat-storing sphere 13 in thermal 11, temperature can pass through accumulation of heat in 1000 DEG C of high temperature above flue gases Ball 13 is exchanged heat, and temperature is rapidly reduced into 70 DEG C or so, then discharged.When in this side thermal 11 heat-storing sphere 13 need sufficient energy or In person's opposite side thermal 11 during 13 energy deficiency of heat-storing sphere, both sides air-introduced machine and air blower are replaced, natural gas line 16 also change inlet channel in the presence of reversal valve, enter simultaneously precombustion from opposite side.Heat-storing sphere in both sides thermal 11 13 alternating heat release accumulation of heats, it is ensured that melting furnace 2 continuously works, and improves aluminum melting efficiency.

Holding furnace 1 is identical with the accumulation of heat principle of melting furnace 2, can be vertical by natural gas line 16 for the ease of natural gas transportation It is opened in the upper heat-insulation layer 18 at the top of holding furnace 1, natural gas can vertically spray into prechamber 12.Accordingly, in holding furnace 1 It two symmetrical thermals 11, can also replace heat release accumulation of heat, ensure the continuity of temperature in holding furnace 1, avoid temperature from declining shadow Ring follow-up aluminium wire wire vent.

The built-in accumulation of heat lead stove being so designed that, melting furnace 2 and holding furnace 1 are using built-in dual alternately storage Heat, installation only needs to fix outer steelframe 5 and bottom steel frame 3 by foundation bolt and ground, relative to common external Lead stove, installation are more convenient.The alternately melting furnace 2 and holding furnace 1 of accumulation of heat heat release, then hot driving can be effectively reduced, reduce heat Loss, energy waste is reduced, can effectively reduce the energy cost in aluminium wire production, effective energy-saving and emission-reduction, there is good economy Prospect.

Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
