Description

Technical Field

[0001] The utility model relates to the technical field of cement raw material proportioning equipment, in particular to a fly ash proportioning device for a cement batching station. Background Art

[0002] The chemical composition of fly ash is similar to that of clay, so in addition to being used as an additive in cement production, fly ash can also replace part of clay as clinker in the production of Portland cement. Replacing clay with a certain proportion of fly ash can reduce electrical energy consumption and carbon emissions in cement production, increase cement output, and reduce production costs. When fly ash is used as a raw material in the cement production process, a proportioning device is required.

[0003] As disclosed in publication number CN212328025U, a fly ash proportioning device for a cement batching station comprises a barrel body, a feed hopper and a lower hopper, a rotating rod is rotatably connected at the center of the inner cavity of the barrel body, first stirring blades are bolted on both sides of the rotating rod, a vertical plate is bolted on the end of the first stirring blade away from the rotating rod, a scraper is bolted on the side of the vertical plate away from the first stirring blade, and second stirring blades are bolted on both sides of the front and back of the rotating rod; the utility model can clean part of the raw materials stuck on the barrel wall during the proportioning operation involving fly ash, so that the mixing and proportioning of the raw materials is more thorough, and some raw materials are prevented from sticking to the surface of the barrel wall, thereby affecting the proportion of the proportion, and solves the problem that some raw materials stick to the inner wall surface of the mixing barrel during the current mixing and proportioning operation of fly ash and other raw materials, resulting in some raw materials unable to be fully mixed and proportioned.

[0004] To sum up, although the proportioning device can achieve the purpose of cleaning the inner wall, there are still certain problems when using it. For example, the stirring and mixing structure of the proportioning device is a single-rod stirring structure. If you want to stir and mix the fly ash evenly, it takes a lot of time and the stirring and mixing efficiency is poor. At the same time, the proportioning device lacks a quantitative unloading structure when in use. When the fly ash is transported to the inside of the barrel, quantitative unloading cannot be carried out, and the staff needs to weigh it well. The staff are very tired and the efficiency is low.
