A kind of novel two-chamber energy-saving smelting furnace is stirred including furnace body, the electromagnetism that the intracorporal burner hearth of furnace is arranged in, is arranged in bottom of furnace body
Device is mixed, the middle part of the burner hearth is split up into two heating rooms by midfeather, is respectively equipped with independent charging on two heating rooms
Mouthful, independent discharge port and be connected with independent combustion system and independent smoke discharging system, the magnetic stirrer, burning
System and smoke discharging system are connect with control system simultaneously, between the top and roof of the furnace siding of the midfeather there are
Gap simultaneously forms airflow channel, and the bottom of the midfeather is equipped at least two circulation ports, and the circulation port is connected to two heating
Room.
In the present invention, the burner hearth bottom is equipped with no magnetic high temperature resistant stainless steel plate.
In the present invention, the outside of the feed inlet is equipped with feeding gate and controls the feeding gate that feeding gate opens or closes
Control device, the feeding gate favour perpendicular.
The beneficial effects of the present invention are: burner hearth is divided into two heating rooms using midfeather by the present invention, under middle interval
Portion's aperture is circulated for the connection of two Room aluminum waters, upper air channel for two Room hot gas, is balanced the pressure between two Room, is guaranteed aluminium
Water and fire box temperature thermal cycle reach balance, and two feeding gates worked independently from each other can be beaten respectively at any time when needed
It opens.Burner hearth bottom is equipped with one piece without magnetic high temperature resistant stainless steel plate and with unification platform great-power electromagnetic blender, and magnetic stirrer is logical
Magnetic field is crossed by the two indoor mutual conversion cycles of aluminum water, to guarantee the balance of aluminum water temperature between two Room.Further, pass through control
System processed controls two heating rooms respectively and heats in turn, while being recycled by magnetic stirrer, can reach optimal life
Produce efficiency and lowest production cost.
Detailed description of the invention
The present invention is further described with embodiment with reference to the accompanying drawing:
Fig. 1 is that the present embodiment opens the main view after feeding gate；
Fig. 2 is the side view of the present embodiment；
Fig. 3 is the top view of the present embodiment；
Fig. 4 is the structural schematic diagram of burner hearth.
Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of novel two-chamber energy-saving smelting furnace provided by the present embodiment, including furnace body 1, setting exist
Burner hearth in furnace body 1, the furnace body 1 are made of metal resistant to high temperature, and its exterior is equipped with heat insulation layers.The middle part of the burner hearth
Two heating rooms 4 are split up by midfeather 3, are respectively equipped with independent feed inlet 5, independent discharge port 6 on two heating rooms 4
And it is connected with independent combustion system and independent smoke discharging system 7, the magnetic stirrer 2, combustion system and smoke discharging
System 7 is connect with control system simultaneously, and the combustion system can heat for electromagnetic heating or heat-accumulating burner, the electromagnetic heating
Including induction coil and high frequency electric source outside heating room 4 is arranged in, the heat-accumulating burner heating includes in setting heating room 4
Burner, connect burner combustion gas.
Further, there are gap and airflow channel 8 is formed between the top and roof of the furnace siding of the midfeather 3,
The height in gap should be greater than 50mm, while meeting air-flow and passing through, midfeather 3 also be avoided to be expanded by thermal energy and squeeze furnace
Thorax.The bottom of the midfeather 3 is set there are two circulation port 9, and the circulation port 9 is connected to two heating rooms 4.The furnace body 1
Bottom is equipped with powerful magnetic stirrer 2, and magnetic stirrer 2 is two 4 bottoms of heating room and is installed therein a circulation
On the corresponding flow trace in hole 9.When magnetic stirrer 2 is opened, the aluminum water of two Room is suitable between the chambers by two circulation ports 9
Hour hands or counterclockwise flow.More smooth to flow the aluminum water of bottom, the burner hearth bottom is equipped with no magnetic high temperature resistant stainless steel
Plate, and the bottom of inboard wall of burner hearth is inclined surface, is gradually decreased from feed inlet 5 to 6 direction of discharge port.In the present embodiment, institute
Stating smoke discharging system 7 is that horn-like and its center line favours burner hearth sidewall.
As preferred embodiment, the outside of the feed inlet 5 is equipped with feeding gate 10 and control feeding gate 10 is opened
Or the charging controlling device for doors 11 closed, the feeding gate 10 favours perpendicular, in order to feeding.
The control system can be PLC control system or LINUX control system etc., only need to time according to setting and sequence
Successively open combustion system, feeding gate, the discharge door etc. of two heating rooms.
The present invention carries out smelting furnace by control system control as follows: two heating rooms 4 are distinguished respectively with A and B, vacation
If the remaining aluminum water for having certain depth, the room B close the door just in heating by ignition, are first turned on the feeding gate of the room A, pass through in original burner hearth
Charging vehicle installs enough aluminium ingots or waste material additional until the room A is full, and the molten aluminum of the room face B of the room B burning at this time heats up, and passes through dual chamber
The airflow channel 8 of top connection conducts the room B hot fume to the room A, then is discharged from the smoke discharging system 7 of the room A, and pass through unlatching
The room B aluminum water is recycled to the room A by magnetic stirrer 2, and the waste material for realizing that the room A is added quickly can sink to the bottom and melt, effective in this way
Avoid waste material directly and flame contact, the scaling loss of aluminium greatly reduces, after the waste material of the room A is all sunk to the bottom, cuts off the room B
Combustion system, then open the combustion system of the room A, then open the feeding gate of the room B, will be installed additional in B furnace it is corresponding squeeze it is useless
Material, aluminium skimmings, foundry returns etc., starting and previously the same working procedure, it is so all and return, reach optimal production efficiency and
Lowest production cost.
It is well known that casting furnace generates a large amount of exhaust gas in combustion, a part is made by regenerative combustion system
It recycles, another part is discharged outward by flue, and exhaust gas temperature is equal with furnace temperature in flue, logical using the room A high-temperature flue gas
When crossing the connection of airflow channel 8 by the room B, 7 outlet of smoke discharging system for passing through the room B in the room B after filled waste material cooling again is preheated, both
Smog discharge temperature is reduced, and reduces smoke discharge amount.Know in industry, metal reduces scaling loss in fusion process
Best method be exactly that metal does not pass through direct flame contact, melting point metal is reached by heat radiation, scaling loss is minimum.And it is exactly
It is managed using this, waste material especially aluminium skimmings in the room AB realize minimal losses ratio during bubble is molten.
The above description is only a preferred embodiment of the present invention, as long as realizing the skill of the object of the invention with essentially identical means
Art scheme belongs within protection scope of the present invention.
