It is flowed and the second interconnecting part 15c being connected to by the degassing room 16 with rear process.
It is that the burning for making the oxygen in gaseous fuel and air mix combining combustion fills in the heating device 15a for keeping room 15 to have
It sets, the acceptable signal from the temperature sensor for keeping room 15 to have is to control melt temperature and environment temperature.
Furthermore as heating device 15a, it is generally desirable to use firing from heat extraction reclaiming type for heat extraction recyclable in burner
Burner.
It is the heat extraction for recycling burner and the device that recycles from heat extraction reclaiming type burner 15a.
That is, the heat of the exhaust after can keeping heating in room 15, guidance is extremely as shown in the construction explanatory diagram of Fig. 5
Preliminary treatment portion 13 is used in the cutting oil that dry, removal is attached in aluminium skimmings.
The attachment such as oil, accumulation are cut in equipment in this way, eliminating, and can reduce the generation of the fire as caused by oil.
Also, preferably in keeping room 15 that exhaust tube 15d is arranged, so that fluorine compounds for occurring of room 15 etc. will be being kept
Corrosive gas is discharged towards the outside (referring to Fig. 3).
Although that is, keep room 15 in have carry out the purified treatment for aluminum melt flux processing situation,
But at this point, corrosive gas is generated from the flux processes composition that investment keeps room 15, if this corrosive gas is attracted to certainly
In heat extraction reclaiming type burner 15a, it is likely that burner internal corrosion can occur.
Therefore, in the exhaust tube 15d for keeping the setting of room 15 that corrosive gas is discharged towards the outside, while in exhaust tube 15d
The switching switch (flashboard) that setting cylinder etc. is opened, closed.
And when flux treatment process, the programming of system is set as flux tupe, stops the investment and heat extraction of aluminium skimmings
The switching of exhaust tube 15d is switched and is opened by the burning of reclaiming type burner 15a.
That is, stopping aluminium skimmings supply feeder 12 when corrosive gas to be discharged towards the outside and keeping room 15
The burning of heat extraction reclaiming type burner 15a, only blows air, while making switching switch actuation and being set to exhaust tube 15d's
Switching switch is set as opening, and the corrosive gas of indoor generation will kept to be discharged towards the outside, so that it will not the rows of being attracted to
In recovery type heat burner 15a.
In addition, heat extraction reclaiming type burner 15a is plural platform as shown in Fig. 3, Fig. 4 of another implementation kenel of the invention
Setting, in order to keep room 15 aluminum melt temperature stability, it is generally desirable to control respective burner combustion as described below
System.
That is, until until keeping the set temperature for the furnace inner environment temperature detection sensor being arranged in room 15,
Make plural platform while burning, a burner combustion is then only made when reaching set temperature.
Furthermore burner combustion amount, same with the adjustment of burner combustion amount can also be adjusted according to the temperature of aluminum melt
When adjustment aluminium skimmings toward melting chamber 14 input amount.
That is, becoming then largely to put into when the situation also higher than keeping the set temperature of room 15, than keeping room 15
It is then put on a small quantity when the also low situation of set temperature.

Toward the aluminium skimmings input amount of melting chamber 14.
By room melt liquid level sensor is kept, it can measure melting chamber 14 and keep the aluminum melt liquid level of room 15 and carry out aluminium
The control of the input amount of bits can prevent the temperature change of aluminum melt caused by due to the increase and decrease of raw material input amount and because burner is poor
It is different and caused by in-furnace temperature rapidly variation.
Also, can steadily put into raw material, and non-once is big by the aluminum melt liquid level in room 15 will kept to keep certain
Amount provides liquid, can will provide liquid as overflow manner and seek certainization of aluminum melt liquid level.
Degassing room 16 is the furnace body portion having with fire proofed wood liner, and the aluminum melt that will be supplied from melting chamber 14 utilizes carbon
The gyrator of SiClx matter or graphite etc. carries out the device of de- device processing while stirring.
Furthermore aluminum melt, benefit is perfused in the inert gas of nitrogen or argon gas etc. by the pipe by having in this gyrator
Degassing process can further be promoted with this.
Added with elements such as silicon or iron in the ingredient of aluminium skimmings.These oxides are largely scattered in the aluminum melt after melting,
As the main reason for reducing the cleannes of melt.
Also, the aluminium cutting swarf generated when machining since its surface area is big, also contains big other than oxide
The oxidation film of amount.The specific gravity of these composite oxides is more great than the ratio of aluminum melt, therefore is easy to be piled up in furnace bottom, the oxygen of accumulation
Compound is handled using flux and degassing process is scattered in aluminum melt again.Therefore, use aluminium cutting swarf as the situation of raw material
When, the degassing process of aluminum melt is quite important.
In order to carry out such degassing process under proper condition, need certainly to control aluminum melt stored in furnace body
Storage capacity.
The storage capacity of the aluminum melt of degassing room 16 is supplied and is stored in from the second interconnecting part 15c of connection holding room 15,
It is that can often be detected by the melt liquid level sensor for being set to filter chamber 17.
It, can be using its reflection of the detection such as being irradiated using the laser for coming self-sustaining room top as melt liquid level sensor
The reflection sensor of position, and detection is because of the e-mail caused by being set to the conducting for keeping the contact and aluminum melt of room side wall
Number immersion-type sensor etc..
In this implementation kenel, melt liquid level sensor can also be set as and filter indoor aluminum melt and contact and conduction detection
Immersion-type sensor either aluminum melt laser is irradiated and is obtained the laser sensor of melt liquid level.
In this way, the liquid that can monitor furnace leaks out, while preventing the storage capacity of aluminum melt from making aluminium lower than below specific level
The situation that melt is integrally cooled down and solidified among melting system.
Furthermore the sensor of the storage capacity as monitoring aluminum melt, may also set up survey other than melt liquid level sensor
Measure the melt temperature sensor of the temperature of melt.
Filter chamber 17 be have the refractory material furnace body of substantially box-like and via third connecting portion 17a and degassing room 16 one
Ground is constituted, and the aluminum melt in the degassing room 16 after degassing process is passed through the ceramic filter that filter chamber 17 has, filtering
And remove the composition part of the aluminium melting system of field trash in melt.
In this filter chamber 17, melt ingredient is averaged, while purified aluminum melt is from the upper of its sidewall of the furnace body
Go out soup portion set by portion and is provided to other calciners or ingot mould etc..
Apparatus for controlling of supply 30 is by being obtained in degassing room 16 via the melt liquid level sensor for being set to filter chamber 17
Melt liquid level message, to control the rotation for supplying the aluminium skimmings supply feeder 12 of aluminium skimmings to preliminary treatment portion 13 from raw material tank 11
IC apparatus or electronic calculator of speed etc. etc. are formed.
In this way, by melting chamber 14, keep in four integrated aluminium melting systems of room 15, degassing room 16, filter chamber 17,
