Description

Technical Field

[0001] This utility model relates to the field of material processing technology, and more specifically, to a material coating device. Background Technology

[0002] Currently, material coating equipment plays an increasingly important role in fields such as chemical engineering. The main function of these devices is to coat solid or liquid materials to improve their properties.

[0003] Taking anode materials as an example, anode materials are an important component of lithium-ion batteries. The carbon coating process of anode materials can improve important properties of graphite such as initial efficiency and expansion, thereby enhancing the performance of lithium-ion batteries. Carbon coating consists of two processes: mixing coating and high-temperature carbonization. Existing solid-phase mixing coating equipment mainly includes VC vertical conical mixers and horizontal mixers, where graphite particles are uniformly mixed with asphalt under the action of the stirring paddle inside the mixer. Existing liquid-phase coating equipment is mainly a fusion machine, where graphite particles are uniformly mixed with liquid asphalt under the action of the inner cylinder. This mixing allows the coating material to form a uniform carbon coating layer on the surface of the graphite particles during high-temperature carbonization.

[0004] However, VC mixing and horizontal mixing equipment can only mix solid coating materials, and cannot guarantee the mixing production and uniformity of liquid coating materials; fusion machines can only perform liquid phase coating and are not suitable for solid phase coating, and have low capacity and high energy consumption, which is not suitable for the huge market demand; in addition, when liquid coating materials are added to graphite materials, they are generally added by direct pouring, which makes it impossible for the liquid coating materials to be evenly distributed in the graphite materials, affecting the coating uniformity and thus affecting the coating effect.

[0005] As can be seen from the above, the existing technology has the problem of poor coating effect of material coating devices. Utility Model Content

[0031] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] To address the problem of poor coating effect in existing material coating devices, this invention provides a material coating device.

[0033] In this embodiment, the material coating apparatus and processing procedure of this application will be specifically described using the solid-liquid phase coating of the negative electrode material as an example. That is, in this embodiment, the material coating apparatus is a negative electrode material coating apparatus. It is understood that when the negative electrode material is mixed and coated, the liquid coating material can be liquid asphalt, and the solid material can be graphite. Of course, the material coating apparatus can also be used for other purposes, and can be selected according to actual needs.

[0034] like Figure 1 As shown, the material coating device includes a liquid addition component 10, a mixing component 20, and a feeding component 30. The mixing component 20 includes a mixing tank, an atomizing nozzle 21, and a first stirring structure. The atomizing nozzle is located at the top of the mixing tank. The liquid addition component 10 is connected to the mixing tank via the atomizing nozzle 21 and is used to add atomized liquid coating material to the mixing tank. The feeding component 30 is connected to the mixing tank and is used to add solid material to the mixing tank. The first stirring structure is rotatably disposed inside the mixing tank and is used to stir and mix the liquid coating material and the solid material.

[0035] This application uses an atomizing nozzle 21 to atomize the liquid coating material, and at the same time, through the stirring and mixing of the first stirring structure, the liquid coating material entering the mixing tank can be evenly distributed in the solid material, which greatly improves the coating uniformity and thus improves the coating effect of the solid-liquid phase material.

[0036] like Figures 4 to 6 As shown, in this embodiment, the first stirring structure includes a first stirring element 22, a second stirring element 23, a stirring rod 24, and a first driving element. The first driving element is driven to the stirring rod 24 and is used to drive the stirring rod 24 to rotate. The first stirring element 22 and the second stirring element 23 are respectively connected and fixed to the stirring rod 24 and are coaxially arranged, with the second stirring element 23 located inside the first stirring element 22.

[0037] Specifically, such as Figures 4 to 5 As shown, the first stirring component 22 includes a stirring frame 221, a first stirring blade 222, and a scraper structure. The stirring frame 221 is connected and fixed to the stirring rod 24 and has a central hollow area. The stirring rod 24 passes through the central hollow area. The first stirring blade 222 is located on the inner side of the stirring frame 221, and the scraper structure is located on the outer side of the stirring frame 221 for scraping the mixture on the inner wall of the mixing tank.

[0038] In this embodiment, the stirring frame 221 is a hexagon symmetrically arranged relative to the stirring rod 24. The left and right sides are vertically aligned to fit the shape of the mixing tank, and the top and bottom are both outwardly protruding V-shapes. One end of the stirring rod 24 extends into the central hollow area of ​​the stirring frame 221, and the top of the stirring frame 221 is connected and fixed to the stirring rod 24, specifically through welding, bolting, or other methods. Furthermore, the bottom of the stirring frame 221 may not be connected to the stirring rod 24; that is, there is a gap between the bottom end of the stirring rod 24 and the bottom of the stirring frame 221. This reduces the resistance of the mixture and facilitates the discharge of the mixture.

[0039] In this embodiment, the first stirring blade 222 includes a rod and blades. The first end of the rod is connected and fixed to the inner side of the stirring frame 221. There are multiple blades, which are spaced apart on the rod and at least one blade is located at the second end of the rod. The rod is perpendicular to the stirring rod 24, and the blades are inclined along the rotation direction of the first stirring blade 222.

[0040] Specifically, there are two blades, designated as the first blade and the second blade. The first blade is located in the middle of the rod body, and the second blade is located at the second end of the rod body, closer to the stirring rod 24. The rod body is horizontally positioned, with its rotation plane being horizontal. The first and second blades are inclined along the rotation direction of the first stirring blade 222. The inclination angles of the first and second blades can be the same or different. When the inclination angles are different, the inclination angle of the first blade can be greater than that of the second blade; for example, the inclination angle of the first blade is 45°, and the inclination angle of the second blade is 30°. Of course, the inclination angles of the blades are not limited to the above parameters and can also be, for example, 40° and 25°, etc., which are not limited here. It can be understood that the inclination angle of the blade is the angle between the blade and the rod body.

[0041] In this embodiment, with Figures 4 to 5 Taking the first stirring element 22 rotating clockwise as an example, the first blade and the second blade are inclined in the clockwise direction, that is, inclined towards the front of the screen, with their windward side facing downward.

[0042] like Figure 4 and Figure 6 As shown, the second stirring component 23 includes a plurality of second stirring blades 231, which are spaced apart along the axial direction of the stirring rod 24. Specifically, the second stirring blades 231 are helical blades. By setting stirring blades and stirring frames with different structural forms, the first stirring structure can fully and effectively stir and mix the mixture in various positions in the mixing tank, thereby improving the uniformity of the mixture.

[0043] In this embodiment, there are multiple first stirring blades 222, and the multiple first stirring blades 222 and multiple second stirring blades 231 are staggered along the axial direction of the stirring rod 24. Furthermore, two rows of first stirring blades 222 are respectively arranged on the left and right sides of the stirring frame 221, with each row of first stirring blades 222 paired together and located on the same horizontal line. Through the above arrangement, the first stirring structure can more thoroughly stir and mix the mixture in the mixing tank, further improving the uniformity of the mixture.

[0044] Furthermore, such as Figures 4 to 5As shown, the scraper structure includes a first scraper 223 and a second scraper 224. The first scraper 223 is located on the left and right vertical sides of the mixing frame 221, while the second scraper 224 is located on the outer side of the V-shaped bottom of the mixing frame 221. In this embodiment, the gap between the scraper structure and the inner wall of the mixing tank can be 2-3 mm to scrape away as much of the mixture as possible from the inner wall of the mixing tank.

[0045] In this embodiment, the scraper structure can be either a multi-segment structure spaced apart or an integral structure extending along the stirring rack 221, which can be selected according to actual needs.

[0046] In this embodiment, the mixture is stirred in the center of the mixing tank by the second stirring blade 231, while the uniformly mixed material is gradually pushed to the periphery. The first stirring blade 222 stirs the mixture in the center and slightly outward. Thus, the combination of the second stirring blade 231 and the first stirring blade 222 enhances the uniformity of the material in the center and increases the stirring range, ensuring overall uniformity of the mixture. The large vertical blades of the stirring frame 221 achieve overall mixing, ensuring that all materials move within the mixing tank and enhancing uniformity. During the mixing process, some material gradually moves to the inner wall and bottom of the mixing tank. If this area cannot be stirred, it will create dead zones, affecting uniformity. Therefore, the first scraper 223 and the second scraper 224 are used to stir and push this portion of material into the interior for mixing.

[0047] Furthermore, such as Figure 3 As shown, the mixing assembly 20 also includes a discharge mechanism 27. The discharge mechanism 27 is located at the bottom of the mixing tank and communicates with the mixing tank. After the mixing and coating are completed, the discharge mechanism 27 opens, allowing the mixture inside the mixing tank to be discharged outwards.

[0048] Furthermore, for liquid phase coating, the viscosity of the liquid coating material varies at different temperatures and changes with ambient temperature. This often leads to unstable addition of the liquid coating material and low-temperature solidification, affecting the coating ratio and mixing uniformity. Therefore, in this embodiment, the liquid addition component 10 includes a first thermostatic module to maintain the liquid coating material at a constant temperature. By setting the first thermostatic module to maintain the liquid coating material at a constant temperature, the viscosity of the liquid coating material can be kept stable, thereby ensuring the stability of the addition amount of the liquid coating material, avoiding low-temperature solidification, thus ensuring the coating ratio and mixing uniformity, further improving the coating effect, and ultimately ensuring the performance of the product.

[0049] Specifically, such as Figure 2As shown, the first temperature control module includes a mold temperature controller 15 and a first heating jacket 16. The first heating jacket 16 is located outside the liquid storage tank 13. The mold temperature controller 15 is connected to the first heating jacket 16 and is used to provide a heat exchange medium to the first heating jacket 16. The mold temperature controller is a mold temperature control device, which is a temperature control equipment, and its heat exchange medium can be water or oil.

[0050] Furthermore, such as Figure 2 As shown, the liquid filling assembly 10 also includes a liquid storage tank 13, which stores the liquid coating material. The mold temperature controller 15 provides power to introduce the heat exchange medium into the first heating jacket 16, where it exchanges heat with the liquid storage tank 13 and then returns to the mold temperature controller 15, thus forming a heat exchange loop. This loop exchanges heat with the liquid coating material in the liquid storage tank 13, maintaining the liquid coating material at a preset temperature. Furthermore, the first temperature control module also includes a first temperature sensing element 17, which measures the temperature inside the liquid storage tank 13, providing a reference for the temperature control operation of the mold temperature controller 15. Specifically, the first temperature sensing element 17 can be a thermometer, temperature sensor, etc.

[0051] Furthermore, in this embodiment, the liquid addition assembly 10 also includes a second stirring structure. The second stirring structure is rotatably disposed within the liquid storage tank 13. By providing the second stirring structure, the liquid coating material within the liquid storage tank 13 is kept in a flowing state, preventing the liquid coating material from solidifying, facilitating its smooth entry into the mixing tank, and ensuring the uniformity of the liquid coating material.

[0052] Specifically, the second stirring structure includes a third stirring blade and a second driving component. The output shaft of the second driving component extends into the liquid storage tank 13, and the output shaft of the second driving component is driven to rotate the third stirring blade within the liquid storage tank 13.

[0053] In this embodiment, both the mixing tank and the storage tank 13 are vertical structures, and the stirring rod 24 and the output shaft of the drive component are both vertically arranged.

[0054] In this embodiment, both the first driving element and the second driving element are motors.

[0055] Furthermore, such as Figure 2 As shown, the liquid addition assembly 10 also includes a raw material tank 11, a liquid addition pump 12, and a liquid outlet pump 18. The raw material tank 11, the liquid addition pump 12, the storage tank 13, the liquid outlet pump 18, and the mixing tank are connected by a liquid delivery pipe. The raw material tank 11 is used to provide liquid coating material. The liquid coating material in the raw material tank 11 is added to the storage tank 13 through the liquid addition pump 12, and the liquid coating material in the storage tank 13 is output to the mixing tank through the liquid outlet pump 18.

[0056] Furthermore, such as Figure 2As shown, the liquid addition assembly 10 also includes a flow meter 14. The flow meter 14 is installed on the downstream delivery pipe of the liquid pump 18. By installing the flow meter 14, the amount of liquid added can be accurately measured, ensuring the proportion of liquid coating material added.

[0057] Furthermore, in this embodiment, the mixing component 20 also includes a second temperature control module for maintaining a constant temperature inside the mixing tank. By setting the second temperature control module, the mixing environment can be kept at a constant temperature, ensuring that the liquid coating material is not affected by the ambient temperature and does not solidify at low temperatures.

[0058] Specifically, such as Figure 3 As shown, the second temperature control module includes a controller, a heating element 25, and a second heating jacket 26. The second heating jacket 26 is disposed on the outside of the mixing tank, and at least a portion of the heating element 25 is located inside the second heating jacket 26 for heating the second heating jacket 26. The controller is electrically connected to the heating element 25 and is used to control the opening and closing of the heating element 25. Furthermore, the second temperature control module also includes a second temperature sensing element 28 for measuring the temperature inside the mixing tank. The second temperature sensing element 28 is also electrically connected to the controller, enabling the controller to control the opening and closing of the heating element 25 based on the real-time temperature measured by the second temperature sensing element 28, thereby maintaining a constant temperature inside the mixing tank.

[0059] In this embodiment, the heating element 25 can be a heating resistance wire. Furthermore, the second temperature sensing element 28 can be a thermocouple.

[0060] like Figure 7As shown, the atomizing nozzle 21 includes a nozzle body 215 and a nozzle valve body 216. The nozzle body 215 has a movable cavity, and the nozzle valve body 216 is movably disposed within the movable cavity. The movable cavity includes a first section, a second section, and a third section connected sequentially. The second section is a transition section, and its inner diameter is smaller than the inner diameters of the first and third sections. A sealing ring 218 is provided at the second section to seal and isolate the first and third sections. The nozzle body 215 has an atomizing nozzle 212, which communicates with the third section of the movable cavity. When the atomizing nozzle 21 is not in operation, the first end of the nozzle valve body 216 abuts against the atomizing nozzle 212, sealing the nozzle 212. A spring 217 is provided within the third section of the movable cavity, and the second end of the nozzle valve body 216 abuts against the spring 217. Under the elastic force of spring 217, the nozzle valve body 216 initially blocks the atomizing nozzle 212 through its first end. The nozzle body 215 also has a pneumatic air source port 214, which is connected to the first section of the moving chamber and the pneumatic air source. The portion of the nozzle valve body 216 located within the first section has a reduced diameter section, forming a compression chamber between the reduced diameter section and the inner wall of the first section. When the external air source is opened, pressurized gas enters the compression chamber, causing the nozzle valve body 216 to move towards the first end. Simultaneously, it overcomes the elastic force of spring 217, causing the second end of the nozzle valve body 216 to move away from the atomizing nozzle 212, thus opening the atomizing nozzle 212. Furthermore, the nozzle body 215 also has a liquid injection port 211, which is connected to the storage tank 13 and the third section of the moving chamber. When the atomizing nozzle 212 is opened, the liquid coating material in the storage tank 13 can enter the third section of the moving chamber through the liquid injection port 211, and then enter the mixing tank through the atomizing nozzle 212. Further, the nozzle body 215 also has an atomizing gas source port 213, which is connected to the third section of the moving chamber and an atomizing gas source. When the atomizing nozzle 212 is opened, the liquid coating material enters the third section of the moving chamber. The atomizing gas source pressurizes the third section of the moving chamber through the atomizing gas source port 213, atomizing the liquid coating material, so that the atomized liquid coating material enters the mixing tank.

[0061] like Figure 3 As shown, the mixing assembly 20 also includes a guide plate 29. The guide plate 29 is disposed inside the mixing tank and above the first stirring structure, and is inclined towards the central axis of the mixing tank. Specifically, there are multiple guide plates 29, which are arranged circumferentially along the mixing tank to form a hopper-like structure. Because the atomized liquid coating material has a wide spray range, the liquid coating material sprayed to the middle of the mixing tank will directly and evenly coat the surface of the solid material and continuously stir and mix. The liquid coating material splashed to the outer ring or the inner wall of the mixing tank can be guided by the guide plate 29 to flow into the middle of the solid material, ensuring uniform mixing.

[0062] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: by setting the material coating device including a liquid addition component 10, a mixing component 20 and a feeding component 30, the mixing component 20 includes a mixing tank, an atomizing nozzle 21 and a first stirring structure. The atomizing nozzle is set at the top of the mixing tank. The liquid addition component 10 is connected to the mixing tank through the atomizing nozzle 21 and is used to add the atomized liquid coating material to the mixing tank. The feeding component 30 is connected to the mixing tank and is used to add solid materials to the mixing tank. The first stirring structure is rotatably set in the mixing tank and is used to stir and mix the liquid coating material and the solid materials. In this way, by setting the atomizing nozzle 21 to atomize the liquid coating material, and by stirring and mixing through the first stirring structure, the liquid coating material entering the mixing tank can be evenly distributed in the solid materials, which greatly improves the coating uniformity and thus improves the coating effect of the solid-liquid phase material.
