Liquid water-soluble fertilizer dry evaporation concentration system

Abstract

The invention discloses a liquid water-soluble fertilizer dry evaporation concentration system. The system comprises a fertilizer storage tank filled with a liquid water-soluble fertilizer; a fertilizer hanging belt disc set with the lower portion immersed into the liquid water-soluble fertilizer is rotationally installed in the fertilizer storage tank, an air outlet located in one side of the fertilizer hanging belt disc set is formed in the top of the fertilizer storage tank, and an air supply device with an air supply outlet extending to the upper portion of the other side of the fertilizerhanging belt disc set is further installed at the top of the fertilizer storage tank. A tray scraping assembly for cleaning the fertilizer hanging belt disc set is further mounted at the upper portion of the fertilizer hanging belt disc set; in the rotating process of the fertilizer hanging belt disc set; the liquid water-soluble fertilizer in the fertilizer storage tank is adhered to the fertilizer hanging belt disc set; when the air supply device generates inlet air, the air can be blown to the upper portion of the fertilizer hanging belt disc set through the air supply outlet, the liquid water-soluble fertilizer adhering to the fertilizer hanging belt disc set is blown, then water in the liquid water-soluble fertilizer is blown out through the air outlet, and the concentration of the liquid water-soluble fertilizer is increased. The system has the advantages of low cost, and simple operation.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizer concentration, and in particular relates to an evaporation concentration device for liquid water-soluble fertilizer. Background technique [0002] Water-soluble fertilizers refer to solid or liquid fertilizers that are dissolved or diluted in water and used for irrigation and fertilization, foliar fertilization, soilless cultivation, soaking seeds and dipping roots, etc. It can be quickly dissolved in water, more easily absorbed by crops, and has a relatively high absorption and utilization rate. At the same time, it also has the advantages of uniform fertilization, no root damage, and convenience. After concentrated fertilization, the local soil solution concentration is too high to cause root burning, which is safe to use. Not only can it be equipped with a large amount of nitrogen, phosphorus, and potassium elements, but it can also be equipped with humic acid, amino acids and...

AI Technical Summary

Problems solved by technology

[0004] At present, in the prior art, liquid water-soluble fertilizers are mainly dried by a heating device to achieve evaporation and concentration. Although this electric heating method has a certain evaporation effect, it is easy to cause the volatilization of active ingredients when this method is used for heating and drying. And better temperature control is required, otherwise the temperature is too high, the components in the water-soluble fertilizer will be decomposed and the fertilizer effect will be reduced; in addition, the electric heating method has certain safety hazards, and the heating cost is high; at the same time, the consumption of steam through the heating method Relatively high, and a large amount of cooling water is needed for cooling during the concentration process, and the operation is complicated
