Description

Technical Field

[0001] The utility model relates to the technical field of high-efficiency separation devices for smelting waste slag in a plasma melting furnace, in particular to a high-efficiency separation device for smelting waste slag in a plasma melting furnace. Background Art

[0002] In the large-scale industrial production process of metal smelting, slag-forming agents are usually added to the molten metal and the smelting liquid to produce a large amount of metal oxide slag with a relatively light specific gravity. How to achieve efficient and safe physical separation of these slags from the molten metal and the smelting liquid is a key factor in improving product quality and production efficiency in industrial production. During smelting, a large amount of metal oxide slag, such as slag zinc blocks, fine slag, etc., will be produced in industrial production. In the subsequent process, the slag needs to be recovered and then subdivided before the next step of the process can be carried out. In the current existing screening technology, manual tools are required for coarse screening, which not only has a very high labor intensity for the staff, but also the screening speed of the waste slag is very slow.

[0003] The smelting waste slag screening device disclosed in the Chinese utility model patent application disclosure CN219112122U has the advantages of enhanced screening effect and convenient recovery after screening, but the smelting waste slag screening device still has disadvantages: First, the smelting waste slag screening device cools the internal waste slag by natural cooling. In actual use, the cooling speed is too slow, which may not be conducive to the implementation of subsequent recovery and processing operations; Second, the smelting waste slag screening device adopts multiple groups of vibrators in conjunction with sieve plates to achieve multiple vibration screening of waste slag. In actual use, since these sieve plates are fixed inside the separation device, their screening efficiency may decrease after long-term use and are not convenient for disassembly and replacement.
