Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fertilizer chelation device, specifically to a kind of liquid fertilizer relatively low temperature chelation device. BACKGROUND

[0002] Chelated micro-fertilizer is also called chelated microelement fertilizer, which is made of chelating agent and essential microelement for plants. Compared with inorganic fertilizer, chelated micro-fertilizer is not easy to be fixed in soil, easy to dissolve in water, not dissociated, can be well absorbed and utilized by plants, and can be mixed with other solid or liquid fertilizer without reducing the fertilizer efficiency of any fertilizer. The existing liquid fertilizer chelation device only stirs the liquid fertilizer by stirrer during use. If the inside of the tank is not heated, the chelation time of water-soluble fertilizer and chelating agent will be longer, which reduces the chelation efficiency of water-soluble fertilizer and affects the chelation efficiency of fertilizer.

[0003] The patent CN221287571U discloses a water-soluble fertilizer emulsification and chelation device, which is provided with a vacuum pump, a cover and a feeding port. First, water-soluble fertilizer and chelating agent are added through the feeding port, and then the cover is covered to seal the tank. The inside of the tank is pumped out by the vacuum pump to improve the heating effect. Then, the heating wire is heated to raise the temperature inside the tank and control the temperature of water-soluble fertilizer and chelating agent at a suitable temperature, so as to improve the chelation efficiency. The utility model is also provided with a spiral stirring rod, which rotates to stir water-soluble fertilizer and chelating agent. The spiral stirring rod reciprocally rotates to mix water-soluble fertilizer and chelating agent, thereby improving the chelation efficiency.

[0004] However, the device has some disadvantages during use. Although the device is provided with heating wire to cooperate with the stirring mode to promote chelation, the solubility of liquid fertilizer changes with temperature.
