technical field

The invention relates to the field of liquid fertilizer production and processing, and specifically discloses a liquid fertilizer production line.

Background technique

Liquid fertilizer, also known as fluid fertilizer, is a liquid product of one or more nutrients required by crops, generally with the theme of N, P, K or one of the three major nutrients, and often includes Many micronutrients. Compared with traditional fertilizers, liquid fertilizers have obvious advantages: ①The formula is flexible and the nutrients are comprehensive. The formula of liquid fertilizer can be designed according to the nutritional requirements of crop growth, and the fertilizer formula can be adjusted according to the different growth of crops. ②Fertilizer is quick and the nutrient utilization rate is high. Liquid fertilizer is a kind of quick-acting fertilizer. At the same time, due to the scientific fertilizer formula, the nutrient utilization rate is high. ③The application is economical, convenient and safe. The application method of liquid fertilizer is simple and uniform. The liquid fertilizer has less impurities, low electrical conductivity, and the concentration can be adjusted conveniently, and it can also be used safely for seedlings.

In the process of liquid fertilizer production and processing, how to accurately control the input of raw materials, improve production efficiency, and ensure the quality of finished products is a difficult problem in the development of liquid fertilizers. There is no dust and smoke in the production process of liquid fertilizer, which reduces the pollution of the environment and reduces the investment cost of purification equipment. Clear liquid type liquid fertilizer products are clear and transparent, clean and free of impurities, while black solutions such as amino acid and humic acid in suspension fertilizers are opaque, but if you observe carefully, there will be no precipitation at the bottom of the bottle after the good product is inverted, and there may be a lot in the bottle of the poor quality product. Solid insoluble matter. Liquid fertilizer products not only need to meet the above physical property requirements, but also need to be uniform, and the nutrient indicators of each batch of finished products must be consistent, which requires accurate measurement during the production process. With the continuous rise of labor costs, the improvement of production efficiency in liquid fertilizer production is very important. Optimizing the liquid fertilizer production line, such as automatic control, is an effective way to solve this problem. The accuracy of the metering equipment in the production line can ensure the precise input of raw materials and the uniformity and qualification of finished products.
