Description

Technical Field

[0001] This utility model belongs to the field of fertilizer production technology, specifically relating to a production system for chelating trace elements with citric acid. Background Technology

[0002] Micronutrients are essential for plant growth and development. Inorganic salt micronutrients are easily affected by factors such as pH and phosphate, which reduces their effectiveness. Chelated micronutrients, however, are unaffected by these factors. Currently, commonly used chelated micronutrients mainly include amino acids and EDTAs, but they still have drawbacks, such as high cost and environmental problems, making them unsuitable for widespread use in the fertilizer industry. Citric acid, on the other hand, is an inexpensive and environmentally friendly organic acid that can be used as a chelating agent to chelate micronutrients.

[0003] However, citric acid chelates a wide variety of trace elements, and the dissolution of these elements requires considerable time. Furthermore, the raw materials used, such as the trace elements themselves, are prone to carrying impurities, which can affect the normal chelation reaction and reduce the quality of the chelate. Moreover, the citric acid chelation reaction requires a specific temperature, and the prolonged dissolution of trace elements also influences the chelation reaction temperature, reducing the chelation effect. Therefore, there is an urgent need for a production system specifically designed for the chelation of trace elements using citric acid. Utility Model Content

[0023] This application provides a production system for chelating trace elements with citric acid, such as... Figures 1-2 As shown, it includes a premixing tank 1 and a chelation reactor 2.

[0024] The premixing tank 1 is equipped with a feed port and a liquid outlet for adding various solid raw materials, including trace elements and citric acid, and water into the premixing tank. Multiple feed ports can be provided, each for adding solid raw materials such as various trace elements, citric acid, and liquid water. The liquid outlet is used to discharge the premixed material.

[0025] Preferably, the feed inlet is located at the top of the premix tank 1, and the liquid outlet is located at the bottom of the premix tank 1.

[0026] The premixing tank 1 is also equipped with a weighing sensor and a first stirring device 11; the weighing sensor is used to measure the added material to facilitate control of the feeding amount. The first stirring device 11 is used to stir and premix the added solid raw materials and water, and to fully mix and dissolve the solid raw materials.

[0027] The chelation reactor 2 is connected to the liquid outlet and is used to carry out a chelation reaction on the mixed and dissolved materials. The chelation reactor 2 is equipped with a heating component, a first temperature sensor, and a second stirring device 21. The heating component is used to heat the chelation reactor, and the temperature sensor is used to detect the temperature inside the chelation reactor.

[0028] The heating element can be a heating wire wound around the chelation reactor or a chelation reactor with a jacket, through which high-temperature steam can be introduced to heat the chelation reactor.

[0029] The first temperature sensor monitors the temperature inside the chelation reactor. When the temperature exceeds the preset range, the heating element adjusts the reactor temperature promptly. By using the heating element and temperature sensor, the temperature of the chelation reactor can be accurately measured and controlled, improving the chelation effect.

[0030] A settling cup 12 with a filtering function is provided between the outlet of the premix tank 1 and the chelation reactor. This cup can intercept undissolved impurities carried in the solid raw material and prevent them from entering the subsequent chelation reactor and affecting the chelation reaction.

[0031] Preferably, the settling cup 12 is a basket filter with a removable filter barrel, which can be removed for cleaning when a large amount of impurities accumulate.

[0032] To promote the dissolution of trace elements, preferably, the water added to the premixing tank is hot water with a temperature >40°C.

[0033] Preferably, a second temperature sensor is provided inside the premix tank 1 to detect the liquid temperature inside the premix tank, which facilitates production control.

[0034] Preferably, each premixing tank 1 is connected to one or more chelation reactors 2. Since the premixing time for trace elements is shorter than that for chelation reactions, one premixing tank can simultaneously supply materials to multiple chelation reactors.

[0035] Preferably, a delivery pump 5 and a control valve 6 are provided between the premix tank 1 and the chelation reactor 2. The delivery pump facilitates the delivery of materials, and the control valve allows for easy adjustment of the material delivery rate.

[0036] Since the premix tanks used in large-scale production are large in volume and tall, the production system provided in this application preferably includes a feeding platform 3 for convenient feeding. Through the feeding platform 3, operators can conveniently feed materials into the premix tank 1.

[0037] Preferably, the feeding platform includes a lifting platform 5, which facilitates operators to transport materials to the top of the premix tank for feeding.

[0038] Therefore, this application separates the trace element mixing and dissolution stage and the chelation reaction stage in the citric acid chelation trace element production process into two different containers: a premixing tank and a chelation reactor. The two containers are then specifically modified according to the characteristics of each stage. A weighing sensor is installed on the premixing tank to precisely control the feed amount. A settling cup is installed between the premixing tank and the chelation reactor to prevent impurities from entering the chelation reactor and affecting the chelation reaction, thereby improving the chelation effect and effectively ensuring the quality of the chelated solution. A heating element and a temperature sensor are installed in the chelation reactor to precisely control the chelation reaction temperature, further improving the chelation effect and yielding a high-quality citric acid chelated solution.
