Description

Technical Field

[0001] The utility model relates to the technical field of screening mechanisms, in particular to a screening mechanism for a belt conveyor. Background Art

[0002] The blast furnace is made of steel plates as the shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: throat, body, waist, belly, and hearth. Due to the advantages of good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production. During blast furnace production, iron ore, coke, and slag flux (limestone) are loaded from the top of the furnace, and preheated air is blown in from the tuyere located at the bottom of the furnace along the furnace periphery. At high temperature, the carbon in the coke (some blast furnaces also spray auxiliary fuels such as coal powder, heavy oil, and natural gas) burns with the oxygen in the air to generate carbon monoxide and hydrogen, which removes oxygen in the iron ore during the rising process in the furnace, thereby reducing iron. The molten iron is released from the iron mouth. The unreduced impurities in the iron ore combine with fluxes such as limestone to form slag, and the generated gas is discharged from the top of the furnace. After dust removal, it is used as fuel for hot blast furnaces, heating furnaces, coke ovens, boilers, etc. The main product of blast furnace smelting is pig iron, and there are also by-products of blast furnace slag and blast furnace gas, which are discharged from the slag mouth. When the slag is discharged, a belt conveyor is required, and a screening machine is required on the belt conveyor for screening. The original belt conveyor screening device adopts the form of wire rope suspension. Since the screening material of our unit is converter slag, the material quality is heavy, causing the screening device to fall off frequently, and the main steel structure of the belt conveyor is heavily deformed. That is, it affects the material processing production time, processing quality and quantity, and increases the labor intensity of employees. Utility Model Content
