Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0028] A device for processing copper electrolytic residual poles in a large-scale copper smelting plant using a continuous blowing process, including a bucket elevator 1, a shaft furnace 2 with a height of 20m, and a heat-insulating furnace between the shaft furnace 2 and the heat-insulating rotary furnace 4 Chute 3, insulation rotary furnace 4 and casting machine ( figure 2 not shown in).

[0029] The method for the equipment of this specific embodiment to process copper electrolytic residual poles has the following steps:

[0030] Feeding and melting: Put the packaged copper electrolytic residues into the hopper through a forklift, and then lift them along the track through the bucket elevator 1 to the feeding port of the shaft furnace 2. The shaft furnace 2 uses natural gas or coal gas as a fuel to provide heat source. ...

Abstract

The invention discloses a cupric electrolysis remnant pole processing method, which comprises the following steps of: charging and melting, namely adding a cupric electrolysis remnant pole into a shaft furnace of which the height is at least 16 meters by using a charger to melt the cupric electrolysis remnant pole into liquid copper; and gravitationally flowing the liquid copper after the melting in the shaft furnace into a heat preservation rotary furnace for heat preservation through a connecting chute between a furnace body and a fining furnace. The method makes use of the height of the shaft furnace to ensure that the cupric electrolysis remnant pole is heated all the time in the ascending discharge process of a high-temperature smoke gas, the temperature of the finally discharged smoke gas is only 250 DEG C, the smoke gas waste heat is fully used, the heat efficiency is improved, the energy consumption is reduced, and the melting speed is accelerated. The invention also discloses a cupric electrolysis remnant pole processing device, which adopts the combination of the shaft furnace and the heat preservation rotary furnace. The processing device fully uses the characteristic of high melting sped of the shaft furnace and the characteristics of high mechanization and automation degree, safe operation, flexible furnace body sizes, good environmental protection effect and low manufacturing cost of the heat preservation rotary furnace, and is particularly suitable for a large-scale copper smelting plant adopting a continuously converting process to process the cupric electrolysis remnant pole.

Description

technical field [0001] The invention relates to copper refining, in particular to a method and equipment for treating copper electrolytic residual electrodes. Background technique [0002] Copper electrolytic residual poles in existing copper smelters are generally added to the converter as cold material. If the capacity of the converter is insufficient, fixed reverberatory furnaces or tilting furnaces are generally used for melting and heat preservation. In this case, the temperature of the high-temperature flue gas emitted during the melting process is As high as 1350°C, ~50% of the heat supply is taken away, and there are problems of low thermal efficiency, slow melting speed, and high energy consumption. Contents of the invention [0003] A technical problem to be solved by the present invention is to make up for the above-mentioned problems in the prior art, and provide a method for treating copper electrolytic butts. [0004] Another technical problem to be solved b...
