Description

Technical Field

[0001] The utility model relates to an aluminum material melting device, in particular to an aluminum material melting device with an impurity removal mechanism, and belongs to the technical field of aluminum material melting. Background Art

[0002] Aluminum melting devices are widely used in aluminum alloy casting, aluminum profile production and other fields. They are one of the indispensable equipment in the aluminum processing industry. Aluminum melting devices are mainly used to heat aluminum alloys or aluminum ingots to the melting point to facilitate subsequent casting or processing.

[0003] Scrap aluminum refers to the residue or waste of aluminum materials generated during the production and consumption process. Scrap aluminum is widely used in the aluminum recycling industry due to its good recyclability and economic value.

[0004] Chinese patent publication CN111023809A discloses an energy-saving kiln for melting aluminum. Aluminum is heated and melted by a heating coil. Impurities in the molten aluminum settle to the bottom of a slag tank. A lever is pulled to open a valve plate, and the aluminum is automatically discharged. The slag tank is raised by a lifting rod to remove the waste slag.

[0005] In actual applications, it has been found that impurities in scrap aluminum come from a variety of sources. Smaller, lighter impurities (such as coatings and certain organic matter) often float on the surface of the molten aluminum, forming a layer of scum, while larger, heavier impurities (such as certain metal particles and unmelted aluminum alloy chunks) may settle at the bottom of the molten aluminum. The aforementioned patent only removes the heavier impurities, and its impurity treatment effect needs to be improved. Therefore, an aluminum melting device with an impurity removal mechanism is proposed. Utility Model Content

Figure 5 The cleaning strips 205 fixed on the first cleaning ring 202, the second cleaning ring 203, and the third cleaning ring 204 are in the same direction in the initial state. At this time, if the cleaning strips 205 are staggered, the flow effect of the molten aluminum liquid will be reduced, and the efficiency of discharging the aluminum liquid through the valve 4 will be reduced.

[0027] Please refer to Figure 3 、 Figure 4 and Figure 5 A first moving block 2041 is fixed to the bottom surface of the third cleaning ring 204, and a stop block 2042 is fixed on the mounting ring 201, and the stop block 2042 is located between the third cleaning ring 204 and the second cleaning ring 203. The first moving block 2041 will rotate under the drive of the third cleaning ring 204, and the first moving block 2041 will abut against the second moving block 2031 during the rotation process. After the first moving block 2041 abuts against the second moving block 2031, the second cleaning ring 203 will be driven to rotate through the second moving block 2031.

[0028] Please refer to Figure 3 and Figure 4 The top surface of the second cleaning ring 203 is fixed with a second moving block 2031 and a reset block 2032, and the reset block 2032 is in contact with the left side of the first moving block 2041.

A positioning block 2033 is fixed on the mounting ring 201, and the positioning block 2033 is located between the third cleaning ring 204 and the second cleaning ring 203.

The top surface of the third cleaning ring 204 is fixed with a rotating frame 2043, and the top surface of the mounting ring 201 is fixed with a moving frame 206.

[0029] Please refer to Figure 3The cleaning mechanism 2 is arranged in the furnace inner shell 105 through the limiting component 3. Specifically, the limiting component 3 includes a limiting ring 301, which is fixed to the inner wall of the furnace inner shell 105. The limiting ring 301 is provided with a limiting hole 302 that passes through the limiting ring 301. The limiting component 3 also includes a limiting column 303, which is fixed to the bottom surface of the mounting ring 201, and the limiting column 303 is in sliding contact with the limiting hole 302. The mounting ring 201 can be placed inside the furnace inner shell 105 through the cooperation of the limiting column 303, the limiting hole 302 and the limiting ring 301.

[0030] Working principle: When melting aluminum, the aluminum is first placed on the cleaning strips 205 of the third cleaning ring 204. The third cleaning ring 204 and the cleaning strips 205 can temporarily store the unmelted aluminum. The molten aluminum will leak out from the gaps between the third cleaning ring 204, the second cleaning ring 203, and the cleaning strips 205 on the first cleaning ring 202, and flow to the bottom of the furnace inner container 105. Larger and heavier impurities will be filtered by the cleaning strips 205 and will not flow to the bottom of the furnace inner container 105.

[0031] After the melting of the aluminum material is completed, the third cleaning ring 204 is rotated by the rotating frame 2043, and the third cleaning ring 204 will drive the first moving block 2041 to move. After the first moving block 2041 moves to the position of the second moving block 2031, the second cleaning ring 203 will be driven to move by the second moving block 2031. The movement of the second cleaning ring 203 will also drive the reset block 2032 to move until the first moving block 2041 is limited by the stop block 2042. At this time, the cleaning strips 205 on the third cleaning ring 204 and the second cleaning ring 203 are arranged in an interlaced manner with the cleaning strips 205 on the first cleaning ring 202. At this time, the mounting ring 201 is pulled vertically upward by the movable frame 206, and smaller and lighter impurities can be cleaned by the three layers of staggered cleaning strips 205. The device can clean smaller and lighter impurities and larger and heavier impurities at the same time.

[0032] When the cleaning mechanism 2 needs to be reset, the third cleaning ring 204 is rotated in the reverse direction. During the rotation, the third cleaning ring 204 will abut against the right side of the reset block 2032, thereby driving the second cleaning ring 203 to rotate in the reverse direction until the first moving block 2041 drives the reset block 2032 to abut against the positioning block 2033. At this time, the third cleaning ring 204 and the second cleaning ring 203 are reset, and the cleaning strips 205 on the first cleaning ring 202, the second cleaning ring 203, and the third cleaning ring 204 are in the same direction.
