An anti-caking agent for water-soluble fertilizer with a large number of elements and its preparation equipment, method and use method

Abstract

An anti-caking agent for water-soluble fertilizer with a large number of elements and its preparation equipment, method and use method, the anti-caking agent includes sodium tripolyphosphate, anhydrous magnesium sulfate powder, anhydrous calcium chloride powder; by weight, tripolyphosphoric acid 60-80 parts of sodium, 10-20 parts of anhydrous magnesium sulfate powder, 10-20 parts of anhydrous calcium chloride powder. The preparation equipment includes a reaction chamber, the sodium tripolyphosphate feed pipe, the anhydrous calcium chloride powder feed pipe, and the anhydrous magnesium sulfate powder feed pipe are respectively connected to the reaction chamber, and the vacuum device is connected to the reaction chamber from the side of the reaction chamber; An air injection pipe is arranged inside the reaction chamber, and air holes are arranged on the surface of the air injection pipe, and the air injection pipe communicates with a high-pressure gas source outside the reaction chamber. The invention is easy to operate, convenient for industrialized production, less in dosage, low in cost, non-polluting to the environment, has double effects of anti-caking and fertilizer, has good anti-caking effect, and can make the looseness of water-soluble fertilizer with a large number of elements more than 92%. , increasing the adaptability of water-soluble fertilizers to different water qualities.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an anti-caking agent for water-soluble fertilizers with a large number of elements and its preparation equipment, preparation method and use method. Background technique [0002] Water-soluble fertilizer (Water Soluble Fertilizer, referred to as WSF), is a multi-component compound fertilizer that can be completely dissolved in water. A new type of fertilizer, which has the characteristics of improving fertilizer utilization rate, energy saving, environmental protection, water saving, fertilizer saving, labor saving, and increasing production. It is one of the important directions for the development of fertilizer forms in the future. [0003] In recent years, with the intensive and large-scale development of agriculture, the further shortage of water resources, and the continuous emergence of large-scale farms, the agricultural area of ​​drip irrigation and sprink...

AI Technical Summary

Problems solved by technology

The agglomerated fertilizer makes it difficult for farmers to use it, which seriously affects the product quality of production enterprises. Enterprises have to use various anti-caking agents to achieve the purpose of anti-caking

[0004] In the prior art, most of the anti-caking agents for compound fertilizers use oil-soluble anti-caking agents, which not only consume hundreds of tons of mineral oil per year, but also cause high cost of use, serious environmental pollution, and cannot meet the requirements of water-soluble fertilizers for water-insoluble substances. Anti-caking agents added to conventional compound fertilizers usually cannot be used in water-soluble fertilizers
