Description

Technical Field

[0002] In blast furnace ironmaking production, high requirements are placed on raw materials. In addition to requiring good metallurgical properties, high requirements are also placed on their particle size, powder content, etc.; blast furnace materials such as machine-burned ore, coke, and natural lump ore need to be screened through the last screening of the under-trough vibrating screen before entering the furnace, so that small-size particles are partially screened out, and the powder attached to the material is screened out through vibration energy to meet the blast furnace material requirements. However, when the raw materials are of poor quality or have a large amount of moisture, especially in autumn and winter production, the raw materials are relatively wet and have a lot of mud powder on them. As the vibrating screen is used for a long time, a part of it will adhere to the screen of the vibrating screen, or be stuck by particulate objects. The vibrating screen cannot effectively remove the adhesion through its own vibration force, resulting in blockage of the vibrating screen mesh and failure to perform screening. At this time, the vibrating screen needs to be stopped and the bottom of the screen needs to be cleaned manually, which not only affects the production progress of the vibrating screen, but also reduces the progress of manual cleaning and places great labor intensity on the staff; therefore, a screen blockage cleaning device is needed, which is required to efficiently clean the sticky material on the screen of the vibrating screen.
