Abstract

The invention discloses an incineration coal slag screening device based on the Internet of Things, which includes a slag feeding pipe scraper assembly, a coal slag crushing assembly, a vibrating coarse screen assembly, a dust screening assembly and a spiral pipe for metal particle screening arranged from top to bottom The screening assembly, the cinder crushing assembly, the vibrating coarse screen assembly, the dust screening assembly and the spiral pipe screening assembly are connected to each other and are arranged in the frame, and are all connected to an Internet of Things controller, and the Internet of Things controller includes an interconnected Single-chip microcomputer, flow detector, weight detector, temperature sensor, frequency conversion controller, metal detector, high-definition camera and magnetic field sensor, also discloses its processing method. The incineration coal slag screening device and its processing method based on the Internet of Things of the present invention perform hierarchical filtration on the coal slag, and recycle different filtrates, and the recovery process is faster and more efficient.

Description

technical field [0001] The invention relates to a screening device, in particular to a coal slag screening device and a processing method thereof. 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...

AI Technical Summary

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
