preparation example Construction

[0032] A method for preparing functional urea that improves the utilization rate of nitrogen fertilizers, comprising adding functional rare earth mineral powder and amino acid chelated trace elements through a mixing and feeding device, an air compressor 10 injection device and a powder pump 11 through a powder material adding port In the molten urea solution pipeline, it is merged with the molten urea solution with a concentration of more than 99.5%. After confluence, it is granulated by a granulation device 5. After granulation, it is sieved by a screening machine 6 in sequence, and an anti-caking agent wrapping machine 7 is used to wrap the oily anti-corrosion agent. Binder and urea packaging machine 8 can be packed.

[0033] Further, a kind of preparation method of the functional urea that improves nitrogen fertilizer utilization rate, comprises the steps:

[0034] Step 1: Put the functional rare earth mineral powder and amino acid chelated trace elements into the mixing f...

Abstract

The invention belongs to a functional urea for improving a nitrogen fertilizer utilization rate, a production apparatus and a production method. The functional urea is prepared from the following rawmaterials in parts by weight: 1-5 parts of a functional rare earth mineral powder, 1-5 parts of amino acid chelated trace elements, and 82-100 parts of a molten urea solution with a concentration of 99.5% or more, wherein the amino acid chelated trace elements comprise amino acid chelated calcium, amino acid chelated magnesium, amino acid chelated boron, amino acid chelated iron and amino acid chelated zinc, and a weight ratio of the amino acid chelated calcium to the amino acid chelated magnesium to the amino acid chelated boron to the amino acid chelated iron to the amino acid chelated zincis 1-2:1-2:1-2:1-2:1-2. The production apparatus has reasonable structural design, convenient operation, simple process, and low cost, a new functional urea complex can be formed by carrying out a chemical reaction of a powder and urea under the premise of preventing a urea melt liquid pipeline from blocking, and the functional urea has the advantages of significantly improving effects and yield.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a functional urea for improving the utilization rate of nitrogen fertilizer, a production device and a production method. Background technique [0002] As a quick-acting neutral fertilizer, urea is suitable for various soils and plants. It absorbs quickly, is easy to store, is convenient to use, and has little damage to the soil. It is currently the largest agricultural demand and the most widely used solid fertilizer. A chemical nitrogen fertilizer with the highest nitrogen content in nitrogen fertilizers, especially for the peak period of fertilizer demand for leafy vegetable crops that require a large amount of nitrogen. Different concentrations of urea aqueous solutions are useful in regulating flower volume, flower and fruit thinning, rice seed production, and control. Insect pests, urea iron fertilizer, etc., have an irreplaceable position of compound fertil...
