Description

Technical Field

[0001] The utility model relates to the field of slag micropowder production, in particular to a hopper for slag micropowder production. Background Art

[0002] Slag powder is a solid waste generated during the blast furnace ironmaking process. This waste can be processed and converted into slag powder. The production of slag powder not only reduces environmental pollution but also improves the overall utilization efficiency of resources. The production process for slag powder primarily involves the following steps: Raw material preparation: Screening the slag to remove impurities and ensure that its chemical composition and particle size meet production requirements. Drying: Reducing the moisture content of the slag, typically to below 5% using drying equipment. Grinding: Using equipment such as vertical mills, European mills, or vibrating mills, the slag particles are mechanically refined to achieve the desired specific surface area. Grading: Grading equipment removes unqualified coarse particles to ensure that the product's fineness meets standard requirements. Collection and packaging: Qualified slag powder that has passed classification enters a storage tank through a collection system and is automatically metered and packaged for easy storage and transportation.

[0003] The current hopper for slag micropowder production, as described in the patent announcement number CN221643367U, includes a hopper body and a stirring mechanism, as well as an opening and closing door, a No. 1 electric push rod and a fan gear. The stirring mechanism includes a rotating roller, a stirring rod and a stirring motor; the rotating roller is rotatably installed in the hopper body, and a plurality of stirring rods are evenly fixed on the rotating roller. The stirring motor is installed on the hopper body to drive the rotating roller to rotate; the two opening and closing doors are symmetrically distributed and rotatably installed at the bottom end of the hopper body using a rotating shaft, the No. 1 electric push rod is hinged on the hopper body, and the piston rod of the No. 1 electric push rod is hinged to the opening and closing door, and fan gears are fixed on the rotating shafts for installing the two opening and closing doors and are engaged with each other.

[0004] Regarding the above-mentioned related technologies, the inventor believes that although the use of a porous sieve plate can screen out larger slag in the slag, some slag with a volume similar to the sieve holes on the porous sieve plate is easily blocked in the sieve holes, thereby reducing the efficiency of subsequent slag screening. Therefore, workers are required to clean and clear the porous sieve plate regularly, which results in higher labor intensity for the workers. Utility Model Content

[0005] The purpose of the utility model is to provide a hopper for producing slag micropowder to solve the problems raised in the above background technology.
