In the recycled aluminum recovery production equipment, various types of smelting furnaces are key equipment in the recycled aluminum recovery process flow, the furnace types comprise rotary furnaces, side shaft furnaces, double-chamber furnaces and other furnace type equipment, the furnace type equipment technology is originated from developed countries in the west, and certain popularization and application are achieved in China in recent years.
In actual production, the problem that a large amount of foreign matters are mixed in the aluminum scrap, including various plastics, paint coatings, oil stains, dust, various other metals and the like, most of the non-metallic foreign matters in the aluminum scrap can be removed through a pretreatment process of the aluminum scrap, but various metal components embedded in the aluminum material are difficult to automatically remove, the metal components mainly comprise iron pieces which are usually put into aluminum smelting equipment together for melting, and the iron pieces are soaked in an aluminum melt and gradually melted, so that the iron elements in the aluminum alloy components exceed the standard, and further the quality of the aluminum melt is polluted.
In a side shaft furnace and a double-chamber furnace which are popularized and applied in the recycled aluminum recovery industry, a considerable amount of aluminum melt must be kept in the furnace all the time to ensure the operation of an aluminum liquid circulating pump, in the furnace types, when iron pieces flow into the melts, the iron pieces are difficult to remove, and only a large amount of pure aluminum can be used for dilution, so that the cost is very large.
The method is also the root reason that many domestic recycled aluminum casting enterprises can only produce low-grade aluminum casting products.

Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1 to 2, the recycled aluminum multi-chamber melting furnace easy to remove iron designed in the first embodiment of the present invention adopts a dual chamber furnace type structure, which includes a furnace body 8, wherein a high-low molten pool design scheme is adopted in the furnace body 8, and a high-melting pool is a feeding chamber 10 and is specially used for feeding solid recycled aluminum raw materials; the low melting pool is an aluminum soup chamber 12 and is specially used for storing molten aluminum, the high melting pool and the low melting pool are in communicated stepped structures, the bottom surface of the feeding chamber 10 is higher than the upper edge of the aluminum soup chamber 12, and the effective capacity of the furnace is determined according to the volume of the low melting pool.
The feeding chamber 10 is shallow in depth, the average depth is only 50-200 mm, the feeding chamber is inclined towards the direction of the aluminum liquid chamber 12 by 2-5 degrees, a slag blocking boss 14 with the height of about 20-50 mm is arranged on the boundary line of the feeding chamber 10 and the aluminum liquid chamber 12 and serves as a slag blocking part, and the slag blocking part is arranged at the boundary line and is beneficial to flowing of aluminum liquid and increasing of the volume of the feeding chamber 10.
The molten bath depth of the aluminum bath chamber 12 can be designed according to the conventional holding furnace, and is usually determined to be between 600 and 1000mm, and the final size is determined according to the furnace capacity.
The side walls 19 of the feeding chamber 10 and the aluminum soup chamber 12 are respectively provided with a furnace door (namely a feeding chamber furnace door 16 and an aluminum soup chamber furnace door 18) and a corresponding furnace door opening and closing mechanism (not shown), and the furnace door structure meets the requirements of the feeding and slag-raking functions in the furnace. The side wall 19 is a slope surface, so that slag is further convenient to remove.
The batch 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 and is capable of meeting the melting capacity requirements of the batch chamber 10.
The aluminum soup chamber 12 can be provided with a low-power heat-preservation combustor 22; the waste heat of the combustor of the feeding chamber 10 can be directly utilized for heat preservation without additionally arranging a combustor.
The bottom of the aluminum soup chamber 12 is provided with a discharging port 24, and the aluminum liquid can be periodically or continuously supplied to the lower process according to different production processes.
During production, all the regenerated aluminum raw materials are put into the feeding chamber 10 and heated to the melting point of aluminum (or slightly higher than the melting point of aluminum), but slightly lower than the melting point of iron for melting, because the bottom surface of the feeding chamber 10 is inclined, molten aluminum flows into the aluminum liquid chamber 12 through the slag blocking boss 14 under the action of gravity, and various iron pieces are difficult to melt due to higher melting points and are retained at the bottom of the feeding chamber 10 under the action of gravity, the specially designed slag blocking boss 14 can prevent fine iron pieces from flowing into a low melting pool, and the separated iron pieces can be removed out of the furnace in a slag removing mode. Repeated tests determine that the bottom surface of the feeding chamber 10 is inclined by 2-5 degrees, which is very 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 state is easily brought into the aluminum soup chamber 12 due to the over-rapid flowing of the aluminum liquid, the purity of the aluminum liquid is influenced, and the workload of slag skimming is increased. The edge of the feeding chamber is provided with a flow guide surface 21 which extends towards the bottom surface of the aluminum soup chamber in an inclined way, so that the downward flow speed of aluminum liquid can be reduced, and splashing is avoided.
Further, under the above inventive concept, the present invention can be further improved as follows:
as shown in figures 3 and 4, in the second embodiment, a partition wall 30 with a through hole 28 for aluminum liquid circulation is adopted to replace a slag stopping boss, and the through hole 28 for aluminum liquid circulation is about 20-50 mm higher than the bottom surface of a molten pool of a feeding chamber; other structures are referred to the first embodiment. Molten aluminum flows into the aluminum soup chamber 12 through the through hole 28 for aluminum liquid to flow through for storage, and various iron parts are difficult to melt due to higher melting point, and can be retained at the bottom of the high melting pool under the action of gravity, and are blocked by the partition wall 30 and retained in the feeding chamber 10.
As shown in FIG. 5, in the third embodiment, two feeding chambers 10 are respectively arranged on two sides of an aluminum soup chamber 12, so as to further improve the productivity of the equipment, and other structures refer to the former two embodiments.
As shown in fig. 6 to 7, in the fourth embodiment of the present invention, a circular aluminum soup chamber 12 structure is used, a circle of feeding chamber 10 is arranged around the outer side of the aluminum soup chamber, a circular slag blocking boss 14 is arranged between the feeding chamber and the circular slag blocking boss, and other structures refer to the former two embodiments. Partition 26 may or may not be provided between the charging chambers 10 as required. 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 a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
