Rotary slag remover for metal smelting dross removal

Abstract

The invention discloses a rotary slag remover for clearing the metal melting dross. The rotary slag remover comprises an upright column with a rotary support, a cantilever, a chain transmission device, a cylinder walking wheel device and a slag rake, wherein the chain transmission device comprises chain wheels, a chain and a drive motor capable of rotating forward and backward; the chain wheels are fixed at the two ends of the cantilever through a bearing seat; the cantilever is fixed at the upper end of the upright column through a cross beam; the bottom of the upright column is provided with a power device for driving the upright column to rotate; the cylinder walking wheel device comprises a cylinder, walking wheels and section steel; the longitudinal two sides of the bottom edge of the cantilever are connected with slide rails; the walking wheels are fixed at the two ends of the longitudinal two sides of the section steel and slide in the slide rails; the cylinder is connected with one end of the section steel through a bracket; the two ends of the chain are respectively fixed on the corresponding walking wheels and bypass the two chain wheels to form an open loop, and the cylinder is driven to reciprocate linearly; a piston rod of the cylinder is connected with a rake arm; the lower end of the rake arm is connected with the slag rake. The slag removal operation is automatically finished online; compared with the prior art, the rotary slag remover disclosed by the invention has the advantages of safety, efficiency and environmental friendliness.

Description

technical field [0001] The invention relates to a rotary slag remover for removing scum in metal smelting. It is mainly used to remove scum on the surface of non-ferrous metals during the smelting process, and can also be used to remove floating objects on the liquid surface under other similar working conditions. Background technique [0002] In the non-ferrous metal pyro-smelting process, when smelting pots are used for pyro-refining (such as crude lead and electrolytic refining), scum will continue to be generated during the operation process, which needs to be removed in time and sent to storage. When the metal refining operation is carried out in the smelting pot, the operating temperature reaches 450-500°C, and due to the addition of additives and continuous stirring, a large amount of harmful smoke and dust will be generated. It is usually necessary to install a sealed fume hood and a ventilation and dust removal system on the melting pot to make the working environm...

AI Technical Summary

Problems solved by technology

However, the existing slag removal methods, no matter whether manual or automatic slag removal, are operated with the smelting pot open, which not only has a great impact on the surrounding environment, but also entrains more molten metal during the slag removal process.

The manual slag removal method is a very difficult task. Each slag removal operation requires the cooperation of 3 to 4 workers. Due to the operation around the open melting pot, the temperature is high and the environment is poor, there are certain safety hazards

However, most of the existing automatic slag removal methods adopt the grabbing method, which requires that the melting pot must be completely opened and other equipment in the pot must be lifted. There is secondary dust and there is more molten metal entrained in the scum
