Description of drawings
Fig. 1, Fig. 2 and Fig. 3 are respectively the utility model the 1st～3rd kind of example structure schematic diagram.
The specific embodiment
Now also the utility model is described in further detail in conjunction with the accompanying drawings by embodiment.
Embodiment 1: as shown in Figure 1.The molten aluminium stove of combined type of the present invention is interconnected to constitute by intercommunication formula chute 4 by an aluminium bits stove 1, a middle stove 2 and two holding furnaces 3.Aluminium bits stove 1, middle stove 2 and two holding furnaces 3 are the molten aluminium stove of the heat accumulating type that is respectively equipped with burner 11.The furnace bottom of middle stove 2 is provided with the furnace bottom that level height is lower than aluminium bits stove 1 relatively, and the furnace bottom of two holding furnaces 3 is provided with the furnace bottom that level height is lower than middle stove 2 relatively.Aluminium bits stove 1 also is connected with middle stove 2 by through type chute 5 simultaneously.When aluminium bits stove 1 centering stove 2 is put aluminium liquid, can be undertaken more convenient unimpeded by through type chute 5.
Embodiment 2: as shown in Figure 2.Present embodiment is on the basis of the foregoing description 1 or following embodiment 3, respectively is provided with coiled pipe 8 respectively in the leg space ventilation chamber 7 in each corresponding accumulation of heat bucket of each burner 11.The import and export 9,10 that coiled pipe 8 in each draft chamber 7 is connected in series after the UNICOM mutually is serially connected with fuel feeding or the feed pipe that the molten aluminium stove melting of combined type is used.Distribute separately on the periphery wall of coiled pipe 8 and be connected with heat absorbing sheet 14.When storage heater 11 work, the flue gas that the low temperature fuel oil that the confession melting of the coiled pipe 8 of flowing through is used or the preparation of water and draft chamber 7 efflux carries out heat exchange, reaches the purpose of further recovery fume afterheat.
Embodiment 3: as shown in Figure 3.Present embodiment is on the basis of the foregoing description 1 or 2, be respectively arranged with the mesh-type that its outlet is made of some equally distributed through holes 18 and all join shower nozzle 15 in the combustion chamber 17 of each burner 11, the oxygen-enriched air outlet that mesh-type is all joined the nitrogen making machine 19 that shower nozzle 15 uses through oxygen enrichment pipeline 13 dehydrogenation when being melting aluminium liquid by magnetic valve 16 respectively is connected.Utilize the combustion chamber 17 of the rich oxygen containing air introducing burner 11 of discharging behind the nitrogen making machine 19 system nitrogen, to help full combustion of fuel.The flow of oxygen-enriched air can be controlled by magnetic valve 16.
Its operation principle is: drop into the aluminium material respectively in aluminium bits stove and middle stove, the aluminium material in the first melting aluminum bits stove is considered aluminium to be worth doing melt in the stove aluminium liquid and is drained into middle stove, and the aluminium material in the centering stove carries out the immersion fusing.After aluminium liquid in the central stove met the requirements of temperature, a wherein holding furnace that again the aluminium liquid in the middle stove is disposed to two holding furnaces carried out the adjustment of aluminium liquid composition, carries out ingot casting after composition adjustment (proportioning components).During this holding furnace is adjusted composition or ingot casting, after the aluminium liquid that melts in the middle stove meets the requirements of temperature, to another holding furnace discharging aluminium liquid, carry out the composition adjustment in succession, treat that this holding furnace ingot casting finishes, this another holding furnace composition adjustment also finishes then ingot casting substantially.Such two holding furnaces can alternate cycles work be realized continuous cast aluminium.
So, the time of the molten vacant cooling of aluminium stove of heat accumulating type can shorten dramatically.Can improve usage ratio of equipment and production efficiency, cut down the consumption of energy.
The composition adjustment of aluminium liquid is to utilize aluminium bits fire grate to put aluminium liquid to holding furnace or the direct composition adjustment that is dosed to holding furnace realization holding furnace aluminium liquid according to the composition needs.The preceding method of adjustment of planting is convenient to control, and it is higher to adjust ratio of precision.The adjustment time of back kind method of adjustment is short, speed is fast.
Aluminium bits stove is put aluminium liquid by intercommunication formula or through type chute centering fire grate, and to two holding furnaces discharging aluminium liquid, the discharging conveying of each stove aluminium liquid is to realize by the height fall between the relevant stove by intercommunication formula chute for aluminium bits stove and middle stove.
When the holding furnace composition is adjusted required time in short-term, by the burner of stove in the control, but fusing is assisted in the fusing of the immersion of centering stove aluminium material.
Regulate the speed when very fast at the holding furnace composition, simultaneously under the situation that the fusing of aluminium bits stove and middle stove can adapt to, or, adapting to regulating the speed of holding furnace by controlling the burner control burn-off rate of aluminium bits stove and middle stove, composition is adjusted ingot casting when can realize two holding furnaces.
Four stoves all can be by the burner control isolated operation of self.
