Description

Vibrating screening device for humic acid fertilizer production

Technical Field

The utility model relates to the technical field of fertilizer production equipment, in particular to a vibrating screening device for humic acid fertilizer production.

Background

Humic acid fertilizer is used as an organic fertilizer rich in various organic substances and nutrient elements required by plant growth and plays a vital role in agricultural planting. The soil-based fertilizer can remarkably improve the physical, chemical and biological properties of soil, enhance the water and fertilizer retention capacity of the soil, promote the activity of soil microorganisms and create a good soil environment for the growth of crops. Meanwhile, the humic acid fertilizer can also directly provide nutrients for crops, improves the stress resistance of the crops, promotes the growth and development of the crops, increases the yield and quality of the crops, and has important significance for guaranteeing the sustainable development of agriculture and grain safety.

In the production process of humic acid fertilizer, the screening link is one of the key steps for ensuring the quality of the product. Conventional humic acid fertilizer screening devices usually adopt a simple vibration screening mode, however, in actual production, the screening mode seriously affects the production efficiency and the product quality.

The humic acid fertilizer has certain viscosity, and adhesion phenomenon easily occurs among the humic acid fertilizer particles due to the influence of factors such as humidity, temperature and the like in the production process, so that a block-shaped structure with different sizes is formed. When the agglomerated humic acid fertilizers enter a traditional vibration screening device, the agglomerated materials are difficult to effectively disperse and move on a screen surface due to the large volume of the agglomerated materials, so that particles meeting the granularity requirement are trapped in the oversize materials in a large amount, and cannot smoothly enter the next production link through a screen. This results in a longer time for the screening process to complete, greatly reducing the screening efficiency and affecting the overall throughput of the production line. Because the agglomerated humic acid fertilizer cannot be effectively broken up and sieved, in conventional sieving devices, the agglomerated materials are often discharged directly as waste. This not only results in a significant waste of raw materials and increased production costs, but also the generation of significant amounts of waste materials can place additional burden on subsequent waste disposal.
