Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer technology, specifically to a water-soluble fertilizer concentration device. Background Technology

[0002] Water-soluble fertilizer concentration is a process that removes most of the water from water-soluble fertilizers using physical or chemical methods, thereby increasing the concentration of effective fertilizer substances. This concentration effectively reduces transportation costs and storage space, and farmers can easily dilute the fertilizer to the appropriate concentration before application. Commonly used water-soluble fertilizers in agriculture, such as urea, ammonium nitrate, and potassium dihydrogen phosphate, can all be concentrated. However, this process requires energy and may alter the chemical properties of the fertilizer; therefore, the appropriate concentration method must be selected based on the specific fertilizer type and intended use.

[0003] Currently, the concentration of water-soluble fertilizers is mostly achieved through heating and evaporation to remove the water. Before evaporation, the water-soluble fertilizer is poured into a concentration tank. However, most concentration tanks are made of corrosion-resistant and high-temperature-resistant steel structures. When the fertilizer is poured into and discharged from the concentration tank, the liquid level of the water-soluble fertilizer in the tank cannot be monitored in a timely manner, which affects the staff's control over the feeding and discharging of materials. Furthermore, the large amount of water vapor generated during the concentration and evaporation of water-soluble fertilizers cannot be effectively collected, resulting in a waste of resources.

The upper liquid level gauge 73 transmits a signal to the first solenoid valve 5 of the feed hopper 6, stopping the feeding. The heating plate 83 is turned on to heat the water-soluble fertilizer in the concentration tank 1. At the same time, the motor 91 is turned on to drive the rotating shaft 92 to rotate.
