Description
Technical Field
The utility model relates to the technical field of metallurgical equipment, in particular to a movable dust hood suitable for a metal smelting process.
Background
The raw material for smelting non-ferrous metal is a mixture of several metals, including gold, silver, copper, zinc and tin. The pyrometallurgical process is the process of separating, extracting and purifying various precious metals from liquid raw materials step by step. At present, the domestic smelting process of nonferrous metals mainly adopts the pyrometallurgy, namely the liquid metal liquid of raw materials in a molten state is heated to different temperature ranges (usually 400-1100 degrees), so that certain metal is precipitated in a solid mixture and floats on the liquid surface, and then the mixture is fished out from a heating pot to be separated from the liquid, thus completing the extraction of certain metal element and completing a pyrometallurgy cycle.
The pyrometallurgical process is more than 10 hours long, during which various substances need to be added to the molten lead bath, such as: the pyrometallurgical smelting of lead mainly includes crude lead ingot, anode stub, carbide and sulfide. When materials are added, because of chemical and physical reactions, strong smoke dust, combustion and detonation can be generated on a smelting site, and lead steam can be continuously released in the long-time high-temperature rolling process of the lead liquid. Smoke dust and clamp steam have great influence on human and surrounding environment, and are key management and control projects required by the state.
Most production sites are provided with smoke dust collection devices, wherein the smoke dust collection devices comprise a fixed dust collection cover and a movable dust collection cover which are square and regular large metal structural members, and smoke dust is collected by a cover body and then is extracted from a ventilating duct. The use is inconvenient and the effect is poor, so the method is basically abandoned. And part of old enterprises are limited by the initial planning of the factory building and do not have enough sites for installing the basic devices. The picture on site in the upper figure reflects that the site has a basic device, and no proper dust collecting device is in a free discharge state.
The pyrometallurgical smelting has two important processes, namely a crude lead ingot adding process and a residual anode (a repeatedly used lead product) adding process, the transfer capacity of the two processes reaches sixty tons, and a lifting mode (driving in a workshop) is required. When the crude lead ingot and the anode scrap are transported, the movable dust collection hood must be removed, the dust collection function cannot be achieved, and the violent smoke in the process is completely emitted and freely discharged into the air. When carbide and sulfide are added, the smoke dust is excited to quickly, intensively and durably empty, but the dust collection cover is limited in structure, the guide airflow is very small and dispersed, and the effect of collecting the smoke dust is limited.
The smelting work platform is built by a steel structure, and due to the impact of heavy objects and the placement of various devices, the work platform is deformed greatly and crowded, so that the large metal structural part for collecting smoke dust is not suitable for production.
Lead pyrometallurgical smelting is the main processing mode at present in China, and the smoke pollution and the lead steam pollution which are limited by the technological method cannot be effectively controlled.
