Description

Technical Field

[0001] The utility model relates to the technical field of airflow spray drying of trace element water-soluble fertilizer solution, in particular to an airflow spray drying tower for trace element water-soluble fertilizer solution. Background Technique

[0002] At present, the trace element fertilizers on the market are mainly simple inorganic salts. After application, the absorption and utilization degree of crops is low, the utilization rate is limited to a certain extent, and the timeliness is poor. Water-soluble salts are ionized into ions in the water-soluble fertilizer solution. Except for non-metal ions such as chlorine, boron, and sulfur, metal elements such as calcium, magnesium, iron, copper, manganese, and zinc can all be soluble inorganic salts. When reacting with PO4 3- 、HPO4 2- 、C03 2- in the soil, insoluble phosphates will be formed and become ineffective for crops. Therefore, when inorganic active trace element fertilizers enter the soil, most of them will lose their activity, and only a small amount can be absorbed by plants, resulting in poor effectiveness. Even if balanced fertilization and balanced fertilizer formulation are carried out, it does not mean balanced absorption. This is the reason why, even though soil testing and balanced fertilization have been carried out, crops still show symptoms of nutrient deficiency. Trace element fertilizers need to be spray-dried. Spray drying technology has been widely applied in the production fields of medicine, chemical industry, food, etc. It can directly obtain powdered dry products by the mass transfer action of the spray tower for non-crystalline solutions. With the continuous improvement of drug quality standards, the existing spray-drying process mode and equipment performance of Fukang Group can no longer meet the requirements, and many unstable problems in main technical indicators such as clarity, toxicity, sterility, and moisture have emerged.

[0003] The existing spray drying tower is not convenient to control the aspect ratio of the spray chamber and the drying residence time. It is easy to form negative pressure in the center of the centrifugal fog chamber, and the equipment needs to perform a balance test to ensure safe operation, which brings great technical challenges to the process. Moreover, the existing spray drying tower is not convenient for feeding, resulting in poor drying time and inconvenient use. Content of the Utility Model

[0015] The utility model provides a gas flow spray drying tower for trace element water-soluble fertilizer solution, which has the following beneficial effects:

[0016] 1. The airflow spray drying tower for trace element water-soluble fertilizer solution is equipped with a cyclone diffusion disk, enabling the hot air to form a swirling flow through the cyclone diffusion disk and come into contact with the liquid droplets of the fertilizer solution, thereby increasing the drying area and drying efficiency. The airflow moves downward along the spiral exhaust duct, which increases the airflow resistance, causing the denser dried product to settle downward into the finished product storage tank, achieving the effect of gas-solid separation. Through the coordinated settings of the air inlet pipe, hot air blower, air supply pipe, return pipe, first control valve, motor base, drive motor, rotating shaft, stirring base, stirring stabilizing shaft, rotating spray pipe, spray head, and stabilizing base, when hot air needs to be supplied during use, the hot air blower is turned on. The hot air blower sucks in external air and heats it, and the heated air is sent into the air inlet pipe through the air supply pipe. The hot air inside the air inlet pipe enters the interior of the drying tower body. Then, the drive motor is started, and the output end of the drive motor drives the rotating shaft to rotate inside the drying tower body. The rotating shaft drives the cyclone diffusion disk to rotate, and the hot air forms a swirling flow and moves downward through the cyclone diffusion disk. At the same time, the rotating shaft rotates inside the stabilizing base through the stirring stabilizing shaft, thus achieving a good drying effect and a high drying efficiency.

[0017] 2. The airflow spray drying tower for trace element water-soluble fertilizer solution is equipped with a spray head, enabling the tower to have the effect of mixing gas and liquid inside and then spraying out. The sprayed liquid droplets are relatively uniform, and the gas enters tangentially to form a turbulent flow, spraying the liquid into a mist. Through the coordinated settings of the feeding pipe, air blower, feeding tube, storage tube, fixing frame, lifting groove, lead screw, servo motor, lifting seat, lifting frame, pressing plate, discharge pipe, and second control valve, when feeding is required during use, first pour the water-soluble fertilizer solution to be dried into the storage tube, then start the servo motor. The output end of the servo motor drives the lead screw to rotate, and the lead screw drives the lifting seat to move downward inside the lifting groove. The lifting seat drives the lifting frame to move downward, and the lifting frame drives the pressing plate to move downward inside the storage tube, causing the water-soluble fertilizer solution inside the storage tube to enter the feeding pipe through the feeding tube. At this time, the air blower is turned on, and the air blower sends external air into the feeding pipe. The water-soluble fertilizer solution will enter the rotating spray pipe through the stirring stabilizing shaft and the stirring base under the action of the airflow. The water-soluble fertilizer solution inside the rotating spray pipe is sprayed out through the spray head. Then, driven by the motor, the sprayed liquid droplets are relatively uniform, and the gas enters tangentially to form a turbulent flow, spraying the liquid into a mist. Then, the sprayed mist comes into contact with the hot air, and the contacted mist is dried. The dried particles fall into the interior of the drying tower body. When discharging is required, the second control valve is opened, and the particles are discharged through the discharge pipe, thus reducing the drying time and achieving the purpose of being more convenient to use.
