Description

Technical Field

[0001] The utility model belongs to the technical field of phosphogypsum production equipment, and in particular relates to a layout structure of phosphogypsum coarse crushing, metering and conveying equipment. Background Art

[0002] Phosphogypsum is a by-product of the industrial wet process of preparing phosphoric acid. For every ton of phosphoric acid produced, about 5 tons of phosphogypsum by-product are produced. In recent years, the resource utilization of phosphogypsum has received widespread attention. Using phosphogypsum as a building material is a relatively mature technical route: one is to use it to prepare cementitious materials, such as preparing cement as a retarder in the sulfuric acid co-production cement process, or to replace natural gypsum to produce building gypsum; the second is to prepare building materials products, such as directly using original phosphogypsum as a water-stabilizing material in road projects, or as a raw material for persulfated phosphogypsum-based concrete, or preparing gypsum products from phosphogypsum building gypsum. Regardless of the technical path, it all starts with the storage, pretreatment, metering and transportation of original phosphogypsum.

[0003] However, there are three application difficulties in long-term storage of phosphogypsum in reservoirs: first, long-term aging will cause compaction and agglomeration, and the particle size of the material is extremely uneven; second, the moisture content is uneven, the internal material has a high moisture content and high viscosity, and the powder fluidity is poor. There is a problem of "easy adhesion" in the production process, which makes it difficult to mix, meter and unload the production equipment, and requires real-time manual intervention and cleaning, which seriously affects production efficiency. The outer layer of material is very easy to dry and powder, causing serious dust pollution; third, the current equipment can only meet a single function of crushing, storage, metering or transportation, and the multi-functional integrated equipment system dedicated to phosphogypsum is relatively rare.

[0004] At the same time, the phosphogypsum metering equipment in the existing technology usually adopts the traditional bucket type, and has certain requirements on the particle size range of the phosphogypsum raw materials. For phosphogypsum blocks that are too large, there is still a risk of clogging the feed port, and the metering accuracy is poor, making it difficult to meet the higher precision batching requirements.
