Abstract

The invention relates to a recycled aluminum smelting cast ingot system. The recycled aluminum smelting cast ingot system comprises an input passageway connected to a corresponding smelting furnace and a buffer tank. A backflow purification pit is formed between the output end of the input passageway and the buffer tank, and an output port of the backflow purification pit is arranged to protrude out of the bottom wall of the backflow purification pit by a certain height and be lower than the bottom face of the output end of the input passageway. A furnace door device of the smelting furnace comprises a furnace door running gear, and the furnace door running gear comprises a safety protection cable connected to a furnace door. The recycled aluminum smelting cast ingot system is reasonable in structure, the quality of casting liquid conveyed by the system is good, and the recycling quality of cast ingots of recycled aluminum is improved.

Description

technical field

[0001] The invention relates to a secondary metal recovery system. In particular, it relates to a secondary aluminum smelting ingot casting system. Background technique

[0002] One of the characteristics of secondary metal smelting and recovery including secondary aluminum is that the smelting liquid contains a large number of sintered ash and impurities with large differences in weight and thickness. When the impurities are not removed in place, it will affect the secondary metal ingot recycling In severe cases, the ingots are like bean curd dregs when they are reused, and cannot be used normally. At the same time, the quality of the ingots is also affected by the oxidation problem during the transportation of the smelting liquid, the temperature change of the metal smelting liquid, etc., due to regeneration There is a long distance between metal smelting and casting ingot process, and the transportation of smelting liquid is also a key and important proce...

Examples

Embodiment 2

[0026] Example 2 as Figure 5 As shown, the input port of the buffer tank (the output port of the backflow purification pit 5) is not provided with a ceramic filter plate. The remaining structures and corresponding purification treatment methods of this example can be similar to those of the above-mentioned embodiment.

Embodiment 3

[0027] Example 3 as Figure 6 shown. The buffer tank 2 is connected with a pouring tank 9, and the outlet of the buffer tank 2 is an undercurrent wide-mouthed outlet 6 arranged on one side wall of the casting tank. The undercurrent wide-mouth output port is provided with an undercurrent purification device composed of an anti-oxidation isolation barrier 7 and a deposition barrier 8 . The undercurrent wide-mouth output port is a rectangular opening whose width is equal to that of the side wall of the corresponding side of the injection groove (the side of the output port). The anti-oxidation barrier 7 and the deposition barrier 8 are respectively composed of upper and lower side walls of a rectangular opening.

[0028] The anti-oxidation barrier 7 isolates the buffer tank from the pouring tank in gas phase. The deposition stop is slightly higher than the bottom wall of the buffer tank. The flow disturbance purification pit is a semi-blind chamber disturbance flow purificati...

Embodiment 4

[0032] In embodiment 4, such as Figure 7 As shown, the bottom wall of the backflow purification pit is wave-shaped, and the output port of the backflow purification pit 5 is arranged on the corresponding peak 15 of the wave-shaped bottom wall of the backflow purification pit, and the wave peak output of the backflow purification pit is provided with a ceramic filter Stencil 4b. The bottom wall of the output end (output port) of the input channel is provided with an inertial freewheeling device 16, and the inertial freewheeling device is extended along the direction of the return purification pit by the bottom wall of the output port of the input channel with the original inclination of the bottom plate of the input channel. The protruding part constitutes. The intercepting side wall surface 14 on the side facing the input direction of the input channel of the return purification pit is provided with an extended return wall surface inclined against the flow direction of the i...
