Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer vibration screening, in particular to a vibration screen device for a compound fertilizer production screening section. Background Art

[0002] Compound fertilizers are chemically produced or mixed with other methods, containing any two or three of the crop nutrients nitrogen, phosphorus, and potassium. Compound fertilizer production often relies on soil testing and formulating to determine soil nutrient levels. This method, based on soil testing and field trials, determines the application rate, timing, and method of nitrogen, phosphorus, potassium, and other minor and trace elements, based on the rational application of organic fertilizers and crop fertilizer requirements, soil fertility, and fertilizer effectiveness. In simple terms, it involves the scientific application of formulated fertilizers under the guidance of agricultural scientists. The core of soil testing and formulating fertilization is to regulate and resolve the conflict between crop fertilizer requirements and soil fertility supply. It also provides targeted nutritional supplementation for crops, specifically targeting deficiencies and providing the required nutrients. This ensures a balanced supply of nutrients to meet crop needs, thereby increasing fertilizer utilization and reducing fertilizer dosage, boosting crop yields, improving agricultural product quality, and saving labor, reducing costs, and increasing income.

[0003] An electric vibrating screen is a device used for physical screening. It primarily relies on mechanical vibration to break up agglomerated particles, which are then filtered through multiple screens to complete the screening process. A key feature of a vibrating screen is its ability to stack multiple screens simultaneously, enabling more precise measurement of the sample's particle size distribution. These features determine that vibrating screens are primarily used for fine screening of medium-fine samples.

[0004] The filter screen on the traditional electric vibrating screen device is fixed on the electric vibrating screen device. When the electric vibrating screen device vibrates, the filter screen is easily vibrated off, causing the filter screen to loosen, resulting in poor screening effect. Based on the fact that piezoelectric ceramics and ultrasonic waves also have vibration effects, the utility model needs to design a new type of vibrating screen device based on relevant technical content.
