Background
The aluminum melting furnace is a key device of a casting production procedure in the aluminum processing industry, and has the function of melting various aluminum solid raw materials at high temperature and then conveying the molten raw materials to a subsequent holding furnace for alloy component adjustment and casting production.
The common aluminum melting furnace in the aluminum processing industry adopts a chamber furnace type structure, the melting process of aluminum metal in the furnace comprises the steps of feeding materials into the furnace, heating to a melting point, solid-liquid conversion, heating aluminum liquid to a proper temperature, discharging and the like, and can be finished within a certain time. Therefore, the chamber type aluminum melting furnace is a typical periodic production operation mode, is matched with a subsequent holding furnace, and can meet various semi-continuous casting production process requirements.
The continuous casting and rolling production process such as the production line of the aluminum plate strip continuous casting and rolling and the aluminum wire rod has continuous and uninterrupted demand for aluminum liquid, and if the traditional chamber furnace type scheme is still adopted, the production process can only be realized by reasonably matching the capacities of the aluminum melting furnace and the heat preservation furnace and the quantity of equipment, but the small capacity is difficult to be increased, and the equipment investment cost is also very high.

2) Because of the feeding mode, the shaft furnace has higher requirements on the type of the raw materials, and raw aluminum ingots are suitable, and irregular raw materials are difficult to feed into the furnace.
3) Because the top is continuously fed, the combustion flue gas floats upwards and is discharged from the feeding barrel, and is difficult to collect, so that the environment-friendly problem of the shaft furnace is more prominent, and the development of the shaft furnace is also restricted to a certain extent.
For the reasons mentioned above, shaft furnaces have been phased out within the industry for years.

Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1 to 2, the fast aluminum melting furnace for continuously discharging aluminum according to the first embodiment of the present invention adopts a dual chamber furnace structure, including a hollow furnace body 8, wherein a high-low molten pool is adopted in the furnace body 8, and the high molten pool is a melting chamber 10 specially used for feeding solid secondary aluminum raw material; the low melting pool is a soup storage chamber 12 and is specially used for storing molten aluminum, the high melting pool and the low melting pool are communicated in a stepped structure, and the effective capacity of the furnace is determined according to the volume of the low melting pool; the edge of the melting chamber 10 is provided with a flow guide surface 21 which extends obliquely towards the bottom surface of the molten aluminum storage chamber 12, so that the downward flow speed of the molten aluminum can be slowed down, and the molten aluminum is prevented from splashing.
The melting chamber 10 has a shallow depth of the molten pool, an average depth of only 50 to 200mm, and an inclination of 2 to 5 degrees toward the low-melting pool. Repeated tests determine that the bottom surface of the melting chamber 10 is inclined by 2-5 degrees, which is quite in line with the production requirement; the angle is less than 2 degrees, so that the aluminum liquid flows slowly; if the angle is larger than 5 degrees, the unmelted solid is easily brought into the storage chamber 12 due to the over-rapid flowing of the aluminum liquid, and the workload of slag skimming is increased.
The soup storage chamber 12 can be designed according to the depth of a melting pool of a conventional holding furnace, and is usually determined to be between 600 and 1000mm, and the final size is determined according to the capacity of the furnace.
The melting chamber 10 and the soup storage chamber 12 are respectively provided with a furnace door (namely a melting chamber furnace door 16 and a soup storage chamber furnace door 18) and a corresponding furnace door opening and closing mechanism (not shown), and the furnace door structure meets the functional requirements of feeding and slagging-off in the furnace. The side wall 19 is a slope surface, so that slag is further convenient to remove.
The melting chamber 10 is equipped with a high power burner 20 which can be mounted on the wall or roof of the refractory side of the furnace with sufficient capacity to meet the melting capacity requirements of the melting chamber 10.
The soup storage chamber 12 can be provided with a low-power heat-preservation combustor 22; the waste heat of the combustor of the melting chamber 10 can be directly utilized for heat preservation without additionally arranging a combustor.
The side wall of the storage chamber 12 is provided with a high flow port 24, and the aluminum liquid can be periodically or continuously supplied to the lower process according to different production processes.
During production, all furnace-filling raw materials are put into the melting chamber 10 for heating and melting, and because the combustion flame directly impacts the raw materials, a very high rapid melting effect can be realized. The molten aluminum flows into the storage chamber 12 for storage under the action of gravity, and after the storage chamber 12 is filled, the subsequent molten aluminum flows to the subsequent holding furnace through the high flow port 24, so that continuous supply of the aluminum liquid is formed.
Because certain high-temperature aluminum liquid is always stored in the storage chamber 12 and has a certain temperature regulating effect on the molten aluminum, the temperature of the aluminum liquid output by the furnace is relatively constant, and the temperature supply requirement of a subsequent heat preservation furnace can be met.
The bottom of the storage chamber 12 is provided with a low flow port 25 for discharging all aluminum liquid in the storage chamber 12 in occasions such as maintenance and the like.
Further, under the thinking of the above utility model, the utility model discloses can also do following improvement:
as shown in FIGS. 3 and 4, in the second embodiment, a melting chamber 10 is disposed on each side of a soup storage chamber 12, thereby further improving the productivity of the apparatus, and other structures refer to the first two embodiments.
As shown in fig. 5 to 6, in the third embodiment of the present invention, a circular structure of the soup storage chamber 12 is used, a circle of melting chamber 10 is disposed around the outer side of the soup storage chamber, and other structures refer to the first two embodiments. Partition plates 26 may be provided between the melting chambers 10, or partition plates 26 may not be provided. The structure of the heat exchanger helps to ensure heat retention and improve heat efficiency.
The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
