Blast furnace slag treatment equipment on basis of internet of things and work process of blast furnace slag treatment equipment

Abstract

The invention discloses blast furnace slag treatment equipment on the basis of an internet of things. The blast furnace slag treatment equipment comprises a slag inlet pipeline scraping assembly, a coal slag smashing assembly, a vibration coarse screening assembly, a dust screening assembly and a spiral pipeline screening assembly for screening metal particles. The slag inlet pipeline scraping assembly, the coal slag smashing assembly, the vibration coarse screening assembly, the dust screening assembly and the spiral pipeline screening assembly are arranged from top to bottom, the coal slag smashing assembly, the vibration coarse screening assembly, the dust screening assembly and the spiral pipeline screening assembly are communicated with one another, are arranged in a framework and areconnected with internet-of-things controllers, and the internet-of-things controllers comprise single chip microcomputers, flow detectors, weight detectors, temperature inductors, variable-frequencycontrollers, metal detectors, high-definition cameras and magnetic field inductors which are connected with one another. The invention further discloses a work process of the blast furnace slag treatment equipment. The blast furnace slag treatment equipment on the basis of the internet of things and the work process have the advantages that coal slag can be classified and filtered by the aid of the blast furnace slag treatment equipment, different filtered substances can be recycled, and recycling procedures are speedy and are high in efficiency.

Description

technical field [0001] The invention relates to a slag treatment equipment, in particular to a slag treatment equipment and its working process. Background technique [0002] A by-product of blast furnace ironmaking, which is mainly used to make building materials after processing. In the blast furnace production process, after smelting various raw materials and fuels into the furnace, in addition to obtaining molten iron and by-product blast furnace gas, the gangue in the iron ore and the ash in the fuel fuse with the flux to form liquid slag. The general temperature is 1450 ~ 1550 ℃, regularly discharged from the slag port and iron port. Usually, the molten slag discharged from the slag mouth is called "upper slag", and the molten iron discharged from the iron hole is called "lower slag". The lower slag is often mixed with a small amount of molten iron. Iron types, operation methods and changes in furnace conditions during the smelting process. CaO, MgO, SiO2 and Al2O3 a...

Problems solved by technology

Usually, the molten slag discharged from the slag mouth is called "upper slag", and the molten iron discharged from the iron hole is called "lower slag". The lower slag is often mixed with a small amount of molten iron. Iron types, operation methods and changes in furnace conditions during the smelting process. CaO, MgO, SiO2 and Al2O3 are the main components of blast furnace slag, accounting for more than 95% of the total. In addition, the slag also contains part of sulfur, titanium , iron, potassium, sodium and other elements, and when the slag is separated, there will still be a certain amount of molten iron bonded to the slag. If this slag is discarded directly, it will cause great waste. These materials can be reused, and the gas If the gasification slag is directly discarded, it will also pollute the environment, and the gasification slag contains a lot of carbon. Before the decarburization reaction, the gasification slag needs to be filtered, but most of the stirrers on the ceramic filter are not cleaned. In this way, the long-term accumulation of slag at the bottom of the slurry tank will cause the agitator to fail to operate normally, thereby reducing the life of the machine, and when pouring the gasification slag, the slag will adhere to the inner wall of the inlet, which will easily cause the inlet to be blocked
