Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulation technology, specifically to a powder coating granulation production system. Background Technology
[0002] Powder coating and granulation of new energy anode materials is a crucial step in the production process, and currently, most industries use single-reactor production. While this method allows for precise control of factors such as material temperature, stirring intensity, and residence time through experimentation, and is convenient to adjust, it also has the following drawbacks:
[0003] ①Low production capacity: Due to the low density and large volume of the negative electrode raw material, and the fact that the reactor is heated from the periphery, the reactor diameter generally cannot exceed 2.0m in order to prevent the temperature at the center of the reactor from being affected. This results in a low single reactor production capacity during intermittent operation.
[0004] ② High energy consumption: Single-reactor operation means that each batch of material must go through the processes of feeding, heating, granulation, cooling and unloading during production. The energy consumption during the heating and cooling processes will result in waste.
[0005] ③ Product index fluctuations: During a single batch operation, the amount of material loaded and the feeding and discharging time are greatly affected by human factors, resulting in fluctuations in product indexes. Summary of the Invention

They are only used to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0042] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0043] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments. Example
[0044] like Figures 1-3 As shown in the figure, this application discloses a powder coating granulation production system for powder coating granulation of new energy anode materials. Its specific structure includes: a frame 1, multiple vertical reactors 2, multiple regulating valves 3, multiple stirring mechanisms 4, multiple flow meters 5, and a controller 6.
[0045] The frame 1 is used to support multiple vertical reactors 2 in a layered manner, ensuring structural stability.
[0046] Multiple vertical reactors 2 are vertically spaced on the frame 1 and connected in sequence. From top to bottom, they are divided into heating reactors 21, several granulation reactors 22 and cooling reactors 23.
[0047] Specifically, the vertical reactor 2 has an inlet at the top and an outlet at the bottom; and the inlets and outlets of two adjacent vertical reactors 2 are vertically coaxial and interconnected, which is used to enable the material to be transferred smoothly, thereby avoiding material jamming.
[0048] For example, in this embodiment, there are two granulation tanks 22, but it is not limited to this, and there may be more or fewer, without specific limitation.
[0049] Multiple regulating valves 3 are installed one-to-one at the outlet of the vertical reactor 2 to regulate the discharge rate.
[0050] Multiple stirring mechanisms 4 are installed one-to-one on the vertical reactor 2 to stir the materials in the vertical reactor 2.
[0051] Multiple flow meters 5 are installed one-to-one at the outlet of the vertical reactor 2 to monitor the discharge rate of the vertical reactor 2.
[0052] The input terminal of the controller 6 is electrically connected to the flow meter 5, and the output terminal is electrically connected to the regulating valve 3.
[0053] Heating devices (not shown in the figure) are installed on both the heating kettle 21 and the granulation kettle 22, and a cooling device (not shown in the figure) is installed on the cooling kettle 23.
[0054] The above technical solution works as follows:
[0055] First, the material is fed into the inlet of the heating vessel 21 by a constant amount via a rotor weigher. Then, the material is heated to 200°C by the heating device on the heating vessel 21. At the same time, the material is stirred by the stirring mechanism 4 on the heating vessel 21 to ensure uniform heating. Finally, the discharge flow rate is collected by the flow meter 5 at the outlet of the heating vessel 21. The controller 6 controls the opening and closing of the regulating valve 3 according to the discharge flow rate collected by the flow meter 5, so that the feed rate and discharge rate remain constant.
[0056] Secondly, the heating kettle 21 discharges into the granulation kettle 22, and the heating device in each granulation kettle 22 gradually raises the temperature. The stirring mechanism 4 makes the temperature rise uniform. The residence time of the powder coating granulation in different temperature ranges can be determined by the number of granulation kettles 22 connected in series and the volume of each kettle. In this process, the feed rate and discharge rate are kept constant by regulating valve 3, flow meter 5 and controller 6.
[0057] Finally, the product enters the cooling kettle 23, where the cooling device lowers the material to the set temperature, facilitating subsequent pneumatic conveying and bagging. The stirring mechanism 4 stirs the material to ensure uniform cooling. Finally, the regulating valve 3, flow meter 5, and controller 6 keep the feed and discharge rates constant.
[0058] Preferably, temperature sensors are provided at both the upper and lower ends of the heating kettle 21 and the granulation kettle 22 to feed back the material temperature to the controller 6. The controller 6 adjusts the heating power of the heating device accordingly to ensure the heating effect.
[0059] Through the above-mentioned settings, this application achieves continuous feeding and discharging throughout the entire process, thereby significantly increasing production capacity. Furthermore, each mixing vessel is set to a constant temperature as required, eliminating the need for repeated heating and cooling, which greatly reduces energy consumption, lowers production costs, and achieves automated control. This ensures constant feeding and discharging, minimizes human intervention during operation, and guarantees stable product quality.
[0060] In some embodiments, the system further includes: multiple insulation layers (not shown in the figure), which are wrapped around the vertical reactor 2 one by one to reduce heat transfer and maintain stable temperature inside the reactor, thereby reducing energy consumption.
[0061] Preferably, the insulation layer is a ceramic fiber layer, which has an extremely low thermal conductivity, can maintain its thermal insulation performance for a long time in high-temperature environments, effectively reduce heat transfer, and has the advantages of good flexibility, corrosion resistance and aging resistance, making it easy to construct and with a long service life.
[0062] In some embodiments, the cooling device is a circulating water jacket (not shown in the figure), which consists of a jacket wall, inlet and outlet pipes, etc., and has the advantages of simple structure, convenient operation, flexible temperature control, good heat dissipation effect, water saving, low maintenance cost and strong applicability.
[0063] In some embodiments, the heating device is a resistance band, which has the advantages of high temperature resistance, long service life, fast heating rate, stable resistance and small power deviation.
[0064] In some embodiments, such as Figure 2 As shown, it also includes: multiple manual valves 7, which are installed one-to-one between two adjacent vertical reactors 2. The valves can adjust the discharge speed of each reactor according to the valve opening, and can cut off the flow of materials in an emergency, thus preventing the accident from escalating.
[0065] In some embodiments, such as Figure 1 As shown, the frame 1 includes: two side supports 11, multiple support platforms 12 and multiple ladders 13; wherein, the two side supports 11 are vertically opposite to each other and spaced apart; the multiple support platforms 12 are located between the two side supports 11 and are arranged vertically and spaced apart, for fixed support of the vertical reactor 2 in a one-to-one correspondence; the multiple ladders 13 are located on one side of the support platform 12 in a one-to-one correspondence.
[0066] The above-mentioned setup ensures structural stability, and allows workers to climb from the ground to each support platform 12 via ladder 13, facilitating the inspection and maintenance of each vertical reactor 2 and thus improving maintenance efficiency.
[0067] In some embodiments, such as Figure 2As shown, the stirring mechanism 4 includes a ribbon stirrer 41 and a variable frequency motor 42; wherein, the ribbon stirrer 41 is installed at the top of the vertical reactor 2; the drive end of the variable frequency motor 42 is connected to the ribbon stirrer 41.
[0068] The variable frequency motor 42 facilitates speed adjustment and ensures mixing efficiency. The ribbon mixer 41 ensures thorough mixing of materials and improves the mixing effect.
