Description

Technical Field

[0001] The utility model relates to an aluminum chip preheating mechanism, in particular to a multi-chute aluminum chip preheating mechanism, which belongs to one of the auxiliary mechanisms of aluminum smelting equipment. Background Art

[0002] Aluminum alloy casting companies, particularly those manufacturing aluminum alloy parts for automobiles and motorcycles, generate large quantities of aluminum alloy chips during the manufacturing process, from casting the blanks to surface treatment. These chips are typically recycled and remelted, but these chips are mostly produced through machine tool processing and contain significant amounts of oil and moisture, requiring heating in a drying kiln before being returned to the furnace for remelting.

[0003] In existing technology, aluminum chips are typically preheated to remove oil and moisture. This production line is complex, expensive, and requires a large floor space, adding to the burden on the manufacturer. Therefore, developing an aluminum chip preheating mechanism with a simple structure, a small footprint, and excellent preheating performance is a pressing technical challenge for those skilled in the art.

[0005] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] A multi-chute aluminum chip preheating mechanism comprises a preheating chamber, a collecting hopper is provided on the preheating chamber, a multi-section connecting chute is provided inside the preheating chamber, and an outlet of the collecting hopper is connected to an inlet of the multi-section connecting chute.

[0007] The multi-section connecting chute is a three-section connecting chute.

[0008] The three-section connecting chute includes a first section chute, a second section chute and a third section chute which are obliquely installed in the preheating chamber. The first section chute and the third section chute are arranged in parallel, and the first section chute is located above the third section chute. The second section chute is arranged crosswise with the first section chute and the third section chute, and the inlet of the first section chute is connected with the outlet of the material collection port, the outlet of the first section chute is connected with the second section chute, and the outlet of the second section chute is connected with the third section chute.

[0009] A vortex chamber is provided at the bottom of the preheating chamber, and the aluminum chips fall into the vortex chamber after passing through the third chute.

[0010] A vibrator is provided at the bottom of the collecting hopper.

[0011] The vibrator is a pneumatic vibrator.

[0012] The beneficial effects of the utility model are as follows:

[0013] This multi-chute aluminum chip preheating mechanism features a preheating chamber that collects heat that would otherwise be wasted at the bottom. Three-stage connecting chutes maximize the retention time of aluminum chips in the preheating chamber without affecting normal material dropout. The collected heat in the preheating chamber dries out any remaining oil and water in the aluminum chips, raising the temperature of the passing aluminum chips, facilitating their melting and reducing energy consumption. Furthermore, the mechanism boasts a simple structure and operation method, allowing it to be installed directly above a melting furnace. This saves floor space and reduces costs for businesses.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to specific embodiments, but the protection scope of the present invention is not limited thereto.

[0022] like Figure 1-6As shown, the multi-chute aluminum chip preheating mechanism of the present invention includes a preheating chamber 1, which collects and utilizes heat that would otherwise be wasted at the bottom. A collection hopper 2 is located above the preheating chamber 1, and a vibrator 3 is located at the bottom of the collection hopper 2. The vibrator is a pneumatic vibrator 3 driven by high-pressure air, which controls the aluminum chips' relatively uniform drop and prevents their accumulation in the collection hopper 2, which could affect normal operation.

[0023] It is further provided that the preheating chamber 1 of the present invention is internally provided with a multi-section connecting chute. Preferably, the multi-section connecting chute in this embodiment is a three-section connecting chute. More preferably, the three-section connecting chute in this embodiment includes a first section chute 4, a second section chute 5 and a third section chute 6 which are obliquely installed in the preheating chamber 1. The first section chute 4 and the third section chute 6 are arranged in parallel, and the first section chute 4 is located above the third section chute 6. The second section chute 5 is arranged crosswise with the first section chute 4 and the third section chute 6. The inlet of the first section chute 4 is connected to the outlet of the collecting port 2, the outlet of the first section chute 4 is connected to the second section chute 5, and the outlet of the second section chute 5 is connected to the third section chute 6. A vortex chamber 7 is provided at the bottom of the preheating chamber 2. Aluminum chips fall into the vortex chamber 7 after passing through the third section chute 6, and the high-temperature aluminum liquid forms a vortex therein.

[0024] When in use, the multi-chute aluminum chip preheating mechanism of this embodiment is installed in a melting furnace, such as Figure 4-6 As shown, after being collected by the collection hopper 2, the aluminum chips pass through the first chute 4, the second chute 5, and the third chute 6 in sequence, maximizing the retention time of the aluminum chips in the preheating chamber 2 without affecting normal material discharge. The side walls and top of the preheating chamber 2 are both provided with an insulation layer 10. The insulation layer 10 is configured as an insulation material. The insulation material can be a commonly used insulation material on the market, such as a common insulating castable in the field. It can collect and retain the heat emitted by the molten aluminum at the bottom, allowing the interior of the preheating chamber 2 to reach a certain temperature while keeping the outer surface temperature low, eliminating the risk of burns. The collected heat in the preheating chamber 2 dries the residual oil and water components in the aluminum chips and heats the passing aluminum chips, facilitating their melting and reducing energy consumption. The aluminum chips in this embodiment pass through the preheating chamber to form high-temperature aluminum liquid 8 in the melting furnace, with the high-temperature aluminum liquid level 9 located below the vortex chamber 7.

[0025] The utility model has a simple structure and easy operation method, and can be directly installed above a melting furnace when in use, thereby saving floor space and reducing enterprise costs.

[0026] The above embodiments are only used to illustrate the inventive concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept should fall within the scope of protection of the present invention.
