Technical Field
[0001] This utility model relates to the field of aerogel intermediate coating mixing technology, and in particular to a high-speed homogenizing mixing device for aerogel intermediate coating. Background Technology
[0002] Aerogel intermediate coatings are functional coatings made by applying aerogel materials in thin film form to the surface of an object. They are characterized by their ultra-light weight, high porosity, and low thermal conductivity, effectively blocking heat transfer. Their hydrophobicity or hydrophilicity can be adjusted according to requirements. They are widely used in building and industrial insulation. Aerogel intermediate coatings are generally composed of resin emulsions, nano-aerogels, and other inorganic non-metallic fillers (such as ceramic microspheres). Therefore, during production and use, they typically require stirring and mixing to ensure the uniformity of the coating material.
[0003] However, existing aerogel intermediate coating mixing equipment typically relies on a single rotation direction and a fixed blade structure to drive material movement. Under unidirectional stirring, lighter components tend to float to the top while heavier components settle at the bottom, resulting in insufficient mixing. In addition, materials such as resin emulsions and nano-aerogels are prone to clumping and agglomeration, and traditional equipment lacks a crushing mechanism, making it impossible to fully disperse them into fine particles, further affecting the mixing effect. At the same time, during equipment operation, the temperature inside the tank gradually increases due to mutual friction and some chemical reactions, causing some raw materials to degrade due to high temperature, affecting the quality of the finished aerogel intermediate coating.
[0004] Therefore, we provide a high-speed homogenizing mixing device for aerogel intermediate coating to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this invention provides a high-speed homogenizing mixing device for aerogel intermediate coating, which aims to solve the aforementioned problems.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a mounting frame, an outer mixing tank welded to the inner side of the mounting frame, an inner mixing tank disposed inside the outer mixing tank, a mixing assembly installed inside the inner mixing tank, the mixing assembly including a top cover disposed at the top of the outer mixing tank, a feed pipe disposed at the front side of the top of the top cover, a fixing frame welded to the center of the top of the top cover, a drive motor installed inside the fixing frame, a drive rod installed at the center of the top cover, an upper stirring blade installed outside the drive rod, and a temperature control assembly disposed outside the outer mixing tank, the temperature control assembly including a circulating water tank installed outside the outer mixing tank.
[0007] Preferably, the drive rod passes through the top cover and is connected to the output end of the drive motor. The drive rod rotates in a clockwise direction. A lower stirring blade is installed at the bottom end of the drive rod, and the blade direction of the lower stirring blade is opposite to that of the upper stirring blade.
[0008] Preferably, a connecting rod is installed in the middle section of the drive rod, and a mixing rod is fixedly installed on the surface of the connecting rod. The mixing rod has a triangular cross-section and its surface is made of rubber.
[0009] Preferably, a scraper is bolted to the end of the connecting rod, the surface of the scraper is made of hard rubber, the scraper is in contact with the inner surface of the mixing inner tank, and a discharge pipe is installed at the bottom of the mixing outer tank.
[0010] Preferably, a temperature-controlled interlayer is provided between the mixing outer tank and the mixing inner tank, and a circulating water inlet pipe is installed at the top of the temperature-controlled interlayer, and a circulating drain pipe is installed at the bottom of the temperature-controlled interlayer. Both the circulating drain pipe and the circulating water inlet pipe are connected to the circulating water tank.
[0011] Preferably, the temperature control interlayer between the mixing outer tank and the mixing inner tank is provided with a flow guide baffle, which has a spiral structure around the surface of the mixing inner tank.
[0012] Preferably, a temperature sensor is installed on the rear side of the top of the top cover, and a temperature control probe is installed on the rear side of the bottom of the top cover. The temperature control probe and the temperature sensor are electrically connected, and the temperature sensor is electrically connected to the circulating water pump and the drive motor.
[0013] This invention provides a high-speed homogenizing mixing device for aerogel intermediate coatings. Compared with the prior art, it has the following advantages:
[0014] 1. This high-speed homogenizing mixing device for aerogel coating uses a drive motor to rotate a drive rod clockwise, causing the upper and lower stirring blades to rotate simultaneously. Because the upper and lower stirring blades are in opposite directions, they carry the floating material from the upper layer to the lower side, while lifting the material settled at the bottom. This allows for more thorough and uniform mixing of the coating material. During the mixing process, the mixing rod breaks up large clumps in the coating material. For brittle particles such as ceramic microspheres, due to their high fluidity and insufficient contact surface, they move up and down with the inclined surface of the mixing rod, ensuring uniform mixing while preventing the brittle particles from being broken, thus guaranteeing the mixing effect.
[0015] 2. This high-speed homogenizing mixing equipment for aerogel intermediate coatings involves circulating water back to the circulating water tank through a circulating drain pipe during the mixing process. This circulating water controls the temperature of the mixing tank, ensuring stable material temperature during mixing. A spiral-shaped baffle allows the circulating water to flow along the baffle after entering the temperature control jacket, improving heat transfer and temperature control. A temperature probe monitors the temperature in the mixing tank in real time and transmits the data to a temperature sensor. When the temperature exceeds the set range, the temperature sensor sends a signal to increase the water flow rate in the circulating water tank, thereby controlling the material temperature in the mixing tank. The equipment also controls the drive motor speed based on temperature conditions, ensuring the mixing process is conducted at suitable temperature and stirring intensity, thus improving the mixing effect of the aerogel intermediate coating.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4This utility model provides a technical solution: a high-speed homogenizing mixing device for aerogel intermediate coating, including a mounting frame 1, an outer mixing tank 2 welded to the inner side of the mounting frame 1, an inner mixing tank 3 disposed inside the outer mixing tank 2, a mixing component 4 installed inside the inner mixing tank 3, the mixing component 4 including a top cover 401 disposed at the top of the outer mixing tank 2, a feed pipe 402 disposed at the front side of the top of the top of the top of the top cover 401, a fixing frame 403 welded to the center of the top of the top of the top cover 401, a drive motor 404 installed inside the fixing frame 403, a drive rod 405 installed at the center of the top cover 401, an upper stirring blade 406 installed outside the drive rod 405, and a temperature control component 5 disposed outside the outer mixing tank 2, the temperature control component 5 including a circulating water tank 504 installed outside the outer mixing tank 2.
[0023] The drive rod 405 passes through the top cover 401 and is connected to the output end of the drive motor 404. The drive rod 405 rotates in a clockwise direction. The bottom end of the drive rod 405 is equipped with a lower stirring blade 407. The blade direction of the lower stirring blade 407 is opposite to that of the upper stirring blade 406.
[0024] During use, the required coating material is injected into the mixing tank 3 through the feed pipe 402. Then, the drive motor 404 is started, which drives the drive rod 405 to rotate clockwise, causing the upper stirring blade 406 and the lower stirring blade 407 to rotate simultaneously. Since the blades of the upper stirring blade 406 and the lower stirring blade 407 are in opposite directions, they will form stirring forces in different directions in the mixing tank 3, so that the coating material can be mixed more fully and evenly.
[0025] A connecting rod 408 is installed in the middle section of the drive rod 405. A mixing rod 409 is fixedly installed on the surface of the connecting rod 408. The cross-section of the mixing rod 409 is triangular, and the surface of the mixing rod 409 is made of rubber.
[0026] During the mixing process, the connecting rod 408 drives the mixing rod 409 to stir the coating material together. At the same time, the mixing rod 409 has a triangular cross-section, which generates stronger shear force when rotating, thereby breaking up large lumps in the coating material. For brittle small particles such as ceramic microspheres, due to their high fluidity and insufficient contact surface, they move up and down with the inclined surface of the mixing rod 409 during stirring. This ensures uniform mixing while preventing the brittle small particles such as ceramic microspheres in the coating material from being broken, thus ensuring the mixing effect.
[0027] The end of the connecting rod 408 is bolted to a scraper 410. The surface of the scraper 410 is made of hard rubber. The scraper 410 is in contact with the inner surface of the mixing inner tank 3. The bottom of the mixing outer tank 2 is equipped with a discharge pipe 411.
[0028] As the connecting rod 408 rotates, the scraper 410 also rotates, thereby scraping off the coating material adhering to the inner wall of the mixing tank 3, preventing the material from sticking to the inner wall, ensuring the mixing ratio of the coating, and avoiding waste. The scraper 410, made of hard rubber, will not damage the inner wall of the mixing tank 3 during the scraping process. After mixing is completed, the mixed coating material can be discharged through the discharge pipe 411.
[0029] A temperature-controlled interlayer is provided between the mixing outer tank 2 and the mixing inner tank 3. A circulating water inlet pipe 501 is installed at the top of the temperature-controlled interlayer, and a circulating drain pipe 503 is installed at the bottom of the temperature-controlled interlayer. Both the circulating drain pipe 503 and the circulating water inlet pipe 501 are connected to the circulating water tank 504.
[0030] During the mixing of the aerogel coating, water in the circulating water tank 504 enters the temperature-controlled jacket through the circulating water inlet pipe 501, and then flows back to the circulating water tank 504 through the circulating drain pipe 503. This allows the circulating water to control the temperature of the mixing inner tank 3, ensuring the temperature of the materials remains stable during the mixing process.
[0031] A flow guide baffle 502 is provided in the temperature control interlayer between the mixing outer tank 2 and the mixing inner tank 3. The flow guide baffle 502 has a spiral structure around the surface of the mixing inner tank 3.
[0032] The spiral-shaped flow guide baffle 502 allows the circulating water to flow along the flow guide baffle 502 after entering the temperature control jacket, thereby improving the heat transfer effect of the circulating water and enhancing the temperature control effect on the material.
[0033] A temperature sensor 505 is installed on the rear side of the top of the top cover 401, and a temperature control probe 506 is installed on the rear side of the bottom of the top cover 401. The temperature control probe 506 is electrically connected to the temperature sensor 505, and the temperature sensor 505 is electrically connected to the circulating water pump and the drive motor 404.
[0034] During mixing, the temperature in the mixing tank 3 is monitored in real time by the temperature control probe 506 and the data is transmitted to the temperature sensor 505. When the temperature exceeds the set range, the temperature sensor 505 will send a signal to increase the speed of the water flow in the circulating water tank 504, thereby controlling the temperature of the material in the mixing tank 3. At the same time, the speed of the drive motor 404 can be controlled according to the temperature to ensure that the mixing process is carried out at a suitable temperature and stirring intensity, thereby improving the mixing effect of the coating in the aerogel.
[0035] Working principle: When using this aerogel intermediate coating high-speed homogenizing mixer, the required coating material is first injected into the mixing tank 3 through the feed pipe 402. Then, the drive motor 404 is started, and the drive motor 404 drives the drive rod 405 to rotate clockwise, which in turn causes the upper stirring blade 406 and the lower stirring blade 407 to rotate simultaneously. Since the blades of the upper stirring blade 406 and the lower stirring blade 407 are in opposite directions, the floating raw material on the upper layer is brought to the lower side during the rotation, while the raw material that has settled at the bottom is brought up, so that the coating material can be mixed more fully and evenly.
[0036] During the stirring process, the connecting rod 408 drives the mixing rod 409 to stir the coating material together. At the same time, the mixing rod 409 has a triangular cross-section, which generates stronger shear force when rotating, thereby breaking up large lumps in the coating material. For brittle small particles such as ceramic microspheres, they are highly fluid and do not have enough contact surface, so they move up and down with the inclined surface of the mixing rod 409 during stirring. As the connecting rod 408 rotates, the scraper 410 also rotates together, thereby scraping off the coating material adhering to the inner wall of the mixing inner tank 3 and preventing the material from sticking to the inner wall.
[0037] Meanwhile, the water in the circulating water tank 504 enters the temperature control jacket through the circulating water inlet pipe 501, and then flows along the guide baffle 502 to improve the heat transfer effect of the circulating water. It then flows back to the circulating water tank 504 through the circulating drain pipe 503. Thus, the temperature of the mixing inner tank 3 is controlled by the circulating water. The temperature in the mixing inner tank 3 is monitored in real time by the temperature control probe 506. When the temperature exceeds the set range, the temperature sensor 505 will send a signal to increase the speed of the water flow in the circulating water tank 504, thereby controlling the temperature of the material in the mixing inner tank 3. At the same time, the speed of the drive motor 404 can be controlled according to the temperature to ensure that the mixing process is carried out under suitable temperature and stirring intensity, thereby improving the mixing effect of the coating in the aerogel.
[0038] Finally, once the materials are mixed evenly to the required standard, open the discharge pipe 411 at the bottom of the mixing tank 2 to discharge the mixed aerogel coating material, thus completing the entire mixing process.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
