Description

Technical Field

[0001] This utility model relates to the field of fertilizer granulation, and in particular to a mixing system. Background Technology

[0002] The production of compound fertilizer includes processes such as granulation, drying, cooling, screening, coating, and bagging. Existing technologies employ granulation methods such as high-tower, drum, and disc granulation. High-tower granulation involves heating solid urea or ammonium nitrate phosphate to melt it, or directly using the concentrated molten liquid obtained from evaporation. Appropriate phosphate fertilizers, potassium fertilizers, fillers, and additives are added to the molten liquid to create a mixed slurry. Current mixing systems are generally constructed using stirred tanks, and multi-stage mixing is used based on the progress of the preparation process to achieve the mixing of various main components. Potassium content is particularly important; however, controlling the production process parameters for products with a potassium content ≥28% is often difficult. The main reason is that the raw material providing the potassium content (potassium sulfate) is difficult to disperse in the mixing system, often resulting in powder floating, ultimately leading to uneven particle size and negatively impacting sales. Therefore, a more rationally structured mixing system is urgently needed to address the shortcomings of existing technologies. Utility Model Content

[0017] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0018] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0019] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0020] To address the aforementioned technical problems, this application provides a stirring system, please refer to the appendix. Figure 1 To be continued Figure 4 The apparatus includes a vessel body 1, a stirring motor 2, and stirring blades 3. The lower half of the vessel body 1 is provided with a guide tube 11. The stirring motor 2 is located at the top of the vessel body 1, and the working shaft of the stirring motor extends into the guide tube 11. The stirring blades 3 are sleeved in the working shaft and are located in the main stirring space formed by the guide tube 11. The stirring blades 3 are surrounded by multiple sets of first stirring plates 31, and each stirring blade 3 has a second stirring plate 32 at its end. The first stirring plates 31 and the second stirring plates 32 are arranged at a preset included angle. The following describes the solution of this application in conjunction with a specific application scenario: During the stirring process, the required components are added to the vessel 1, and the stirring motor 2 drives the stirring blade 3 to rotate. In particular, the stirring blade 3 includes a first stirring plate 31 and a second stirring plate 32. The first stirring plate 31 has a larger volume, which can effectively disperse the component raw materials in the initial state. After a certain period of stirring, the smaller second stirring plate 32 is used to further finely disperse the component raw materials. It can be seen that by the cooperation of the first stirring plate 31 and the second stirring plate 32, the dispersion shearing ability can be increased, effectively avoiding the phenomenon of raw material floating powder during the granulation mixing process, making the component mixing more uniform and the overall granulation quality better.

[0021] In this embodiment, the end of the first stirring blade 31 is arranged in a spiral rotation of 30 degrees. At this angle, when the first stirring blade 31 stirs and disperses the component raw materials, the component raw materials form a turbine shape, further improving the dispersion performance. In a further embodiment, the second stirring blade 32 has a flat structure with a preset included angle between 100 and 150 degrees. The second stirring blade 32 can effectively improve the ability to finely divide small clumps of components. The flat structure is fixed to the end of the first stirring blade 31 by welding. This connection method is firm and not afraid of corrosion of the raw material components.

[0022] In this embodiment, the inner wall of the vessel body 1 is also provided with an auxiliary dispersing plate 4. The lowest position of the auxiliary dispersing plate 4 is higher than the upper cylinder surface of the guide cylinder 11. During the stirring process, the component raw materials form a flow circulation through the vessel wall. When the component raw materials pass through the vessel wall, the blade of the auxiliary dispersing plate 4 cuts the component material, which also helps to disperse it.

[0023] In this embodiment, a discharge pipe 5 is also included. The inlet end of the discharge pipe 5 is connected to the inner cavity of the vessel body 1, and the outlet end is inclinedly disposed on the outer wall of the vessel body 1. It is easy to understand that when the dispersed component raw materials are collected from the discharge pipe 5 and transferred to the granulation device, the granulation device forms uniform granules from the component raw materials, and then the technicians package them for the next process. The inclined discharge pipe 5 can effectively discharge the dispersed component raw materials located at the bottom of the vessel smoothly. In a further embodiment, the height of the inlet end of the discharge pipe 5 from the bottom of the vessel is the same as the height of the first stirring plate 31 from the bottom of the vessel. Under this height design, the component raw materials can be discharged better. The specific position of the discharge pipe 5 is that the angle between the discharge pipe 5 and the outer wall of the vessel body 1 is 20 degrees, and the inner diameter of the discharge pipe opening is 11 cm.

[0024] In this embodiment, the top of the vessel body 1 is also provided with a discharge port 12, and an electric clamp valve is arranged at the discharge port 12; it is easy to understand that the electric clamp valve can realize the timely opening and closing of the valve port, and technicians can accurately feed materials.

[0025] In this embodiment, the guide tube 11 is fixedly connected to the inner wall of the vessel body 1 by multiple connecting columns 13 on its surface. The function of the guide tube 11 is to make the mixing of the component materials more uniform. Under the action of the guide tube 11, the component raw materials rotate, circulate and mix fully, and finally form a system with balanced mass. In the specific scheme, the diameter of the guide tube 11 is 120cm and the height is 50cm. The guide tube 11 is 25cm above the bottom of the vessel and 30cm away from the vessel wall. The distance of the first stirring plate 31 from the bottom of the vessel is 60cm.

[0026] The advantages of this utility model are: 1. By combining the first and second stirring plates, the dispersion and shearing capacity is increased, effectively avoiding the floating of raw materials during the granulation mixing process, resulting in more uniform mixing of components and better overall granulation quality. 2. The inner wall of the vessel is also equipped with auxiliary dispersing plates, the lowest position of which is higher than the upper cylinder surface of the guide tube. During the stirring process, the component raw materials form a flow circulation through the vessel wall. When the component raw materials pass through the vessel wall, the blade of the auxiliary dispersing plate cuts the component material, which also helps to disperse it.

[0027] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
