Technical Field
[0001] This utility model relates to a mixing device for coating production, and in particular a raw material mixing device for water-based ceramic coating production. Background Technology
[0002] Water-based ceramic coatings are a new type of green, safe, healthy, and environmentally friendly coating. The production process requires the use of a mixing device to thoroughly mix the raw materials. Currently, common mixing devices for water-based ceramic coating production mainly consist of a mixing motor, a mixing shaft, and mixing blades mounted on the shaft. However, the mixing speed is constant and determined by the mixing motor. The mixing state of the raw materials differs between the early and later stages of mixing. If a uniform mixing speed is used, it is easy for the raw materials to clump together, or only the materials on the inner side around the mixing shaft are well mixed, while the materials on the outer side remain dispersed, resulting in poor overall mixing. Therefore, existing mixing devices for water-based ceramic coating production suffer from poor mixing performance. Utility Model Content
[0003] The purpose of this invention is to provide a raw material mixing device for the production of water-based ceramic coatings. This invention has the advantage of good mixing effect.
[0004] The technical solution of this utility model: a raw material mixing device for the production of water-based ceramic coatings, comprising a frame, a mixing tank with an open top, a feed pipe located on the side of the mixing tank, and a discharge pipe located on the bottom of the mixing tank. A lifting device is provided on one side of the mixing tank, and a top cover is provided on the lifting device, the diameter of which is larger than the diameter of the mixing tank. A medium-speed motor is installed on the top surface of the top cover, and a first mixing shaft is connected to the medium-speed motor located directly below the top cover. A three-bladed propeller is provided at the end of the first mixing shaft, and a serrated disc is provided above the three-bladed propeller. A second mixing shaft is installed on the inner bottom surface of the mixing tank, one end of which is connected to a low-speed motor located directly below the mixing tank. An upper blade is provided at the other end of the second mixing shaft inside the mixing tank, and a reverse transmission is provided between the upper blade and the bottom surface of the mixing tank on the second mixing shaft. The device features a lower layer of blades on its reverse transmission mechanism. A medium-speed motor and a first stirring shaft perform medium-speed stirring in the upper part of the mixing tank, while a low-speed motor and a second stirring shaft perform low-speed stirring in the lower part. This creates a two-stage dispersion gradient within the mixing tank, refining the entire stirring process and ensuring efficient dispersion. A three-bladed propeller generates a combined radial and axial flow field within the mixing tank, driving the raw materials to form vortices. Combined with a toothed disc, shear force is applied to the raw materials within the vortices, dispersing some ceramic powder agglomerates and preventing lumpy materials from appearing in the final water-based ceramic coating, thus ensuring effective stirring. The upper and lower blades, rotating in opposite directions, enhance the axial flow of the raw materials at the bottom of the mixing tank, preventing material accumulation dead zones and further ensuring the stirring effect.
[0005] In the aforementioned raw material mixing device for producing water-based ceramic coatings, the reverse transmission device includes a lower bevel gear mounted on a second mixing shaft, and a reverse transmission sleeve mounted on the second mixing shaft above the lower bevel gear; an upper bevel gear symmetrically arranged with the lower bevel gear is provided at the bottom end of the reverse transmission sleeve, and a fixing seat for fixing the lower blades is provided at the top end of the reverse transmission sleeve; a C-shaped connecting sleeve is provided between the reverse transmission sleeve and the second mixing shaft, and a transversely arranged intermediate bevel gear is rotatably mounted in the middle of the connecting sleeve; both the upper and lower bevel gears are meshed with the intermediate bevel gear; the connecting sleeve not only fixes the position of the reverse transmission sleeve, but also serves as a mounting seat for the intermediate bevel gear, making the overall structure more compact.
[0006] In the aforementioned raw material mixing device for producing water-based ceramic coatings, a protective shell is provided at the position corresponding to the connecting sleeve on the second mixing shaft. The connecting sleeve, upper bevel gear, lower bevel gear, and intermediate bevel gear are all housed inside the protective shell. The protective shell is fixedly installed on the bottom surface of the mixing tank. By providing the protective shell, the connecting sleeve, upper bevel gear, lower bevel gear, and intermediate bevel gear are protected, preventing transmission jamming caused by contact with the internal raw materials, thus ensuring operational stability and service life.
[0007] In the aforementioned raw material mixing device for the production of water-based ceramic coatings, multiple ultrasonic transducers are arranged on the bottom surface of the top cover, and all ultrasonic transducers are arranged in a ring on the outer circumference of the first stirring shaft. By utilizing the cavitation effect generated by the ultrasonic transducers, not only can the agglomerates in the raw materials be further crushed, but the adsorption of surfactants on the surface of the fractional raw materials can also be promoted, thereby improving the stability after dispersion and further enhancing the overall mixing effect.
[0008] In the aforementioned raw material mixing device for the production of water-based ceramic coatings, the lifting device includes two lifting frames symmetrically arranged on both sides of the mixing tank. Each lifting frame has a ball screw on its side away from the mixing tank. A servo motor is connected to the end of the ball screw, and a sliding seat is slidably installed on the ball screw. A lifting seat is installed between the top surfaces of the two sliding seats. The medium-speed motor is fixedly installed on the bottom surface of the lifting seat.
[0009] In the aforementioned raw material mixing device for the production of water-based ceramic coatings, a plurality of annular support columns are evenly distributed on the bottom surface of the lifting seat on the outer circumference of the medium-speed motor. The bottom surface of each support column is fixedly connected to the top surface of the top cover. The use of support columns increases the connection stability between the lifting seat and the top cover, thereby improving the stability of the structure.
[0010] In the aforementioned raw material mixing device for producing water-based ceramic coatings, a feed gear pump is installed on the feed pipe; a discharge gear pump is installed on the discharge pipe; a controller is provided on the side of the frame, and the lifting device, medium-speed motor, low-speed motor, feed gear pump, and discharge gear pump are all electrically connected to the controller; by setting the controller, the feeding operation of the feed pipe, the discharge operation of the discharge pipe, and the start and stop of the lifting device, etc., are controlled, which facilitates use.
[0011] Compared with existing technologies, this utility model improves the existing raw material mixing device for water-based ceramic coating processing. By equipping the mixing tank with a medium-speed motor, a first mixing shaft, a low-speed motor, and a second mixing shaft, the medium-speed motor and the first mixing shaft perform medium-speed mixing in the upper middle part of the mixing tank, while the low-speed motor and the second mixing shaft perform low-speed mixing in the lower middle part. This creates a two-stage dispersion gradient within the mixing tank, enabling graded and refined mixing and ensuring efficient dispersion. Furthermore, by equipping the first mixing shaft with a three-bladed propeller and a toothed disc, the three-bladed propeller generates a combined radial and axial flow field within the mixing tank, driving the raw material to form a vortex. The toothed disc then applies shear force to the raw material within the vortex, causing some of the ceramic material to disperse. The dispersion of powder agglomerates avoids the presence of lumpy raw materials in the final water-based ceramic coating, ensuring effective mixing. By installing upper and lower blades on the second mixing shaft, with the lower blades connected to the second mixing shaft via a reverse transmission device, the upper and lower blades rotate in opposite directions when the second mixing shaft drives them. This reverse rotation of the upper and lower blades enhances the axial flow of the raw material at the bottom of the mixing tank, preventing material accumulation in dead zones and further ensuring effective mixing. Simultaneously, a lifting device facilitates the vertical movement of the top cover, medium-speed motor, and second mixing shaft, enabling easy cleaning and maintenance of the three-bladed propeller on the second mixing shaft, thus simplifying operation.
[0012] Furthermore, this invention also incorporates a connecting sleeve between the reverse transmission sleeve and the second stirring shaft. This connecting sleeve not only fixes the position of the reverse transmission sleeve but also serves as a mounting base for the intermediate bevel gear, resulting in a more compact overall structure. A protective outer shell protects the connecting sleeve, upper bevel gear, lower bevel gear, and intermediate bevel gear, preventing transmission jamming due to contact with internal raw materials and ensuring operational stability and service life. Multiple ultrasonic transducers are installed on the bottom surface of the top cover. The cavitation effect generated by these transducers further pulverizes agglomerates in the raw materials and promotes the adsorption of surfactants on the surface of the dispersed raw materials, improving dispersion stability and overall stirring effect. Multiple support columns are installed on the bottom surface of the lifting base, each fixedly connected to the top cover, increasing the connection stability between the lifting base and the top cover and enhancing structural stability. A controller is used to control the feeding operation of the feed pipe, the discharging operation of the discharge pipe, and the start / stop of the lifting device, facilitating operation. Therefore, this invention not only improves the stirring effect, but also has the advantages of high stirring speed, convenient use, high working stability and long service life.

The device is characterized by: a lifting device on one side of the mixing tank 2, a top cover 5 directly above the mixing tank 2 with a diameter larger than that of the mixing tank 2; a medium-speed motor 6 mounted on the top surface of the top cover 5, connected to a first stirring shaft 7 directly below the top cover 5; a three-bladed propeller 8 at the end of the first stirring shaft 7, with a serrated disc 9 above the three-bladed propeller 8; a second stirring shaft 10 mounted on the inner bottom surface of the mixing tank 2, one end of which is connected to a low-speed motor 11 directly below the mixing tank 2; an upper blade 12 inside the mixing tank 2 at the other end of the second stirring shaft 10, with a reverse transmission device on the second stirring shaft 10 between the upper blade 12 and the bottom surface of the mixing tank 2, and a lower blade 13 mounted on the reverse transmission device.
[0021] The reverse transmission device includes a lower bevel gear 14 mounted on the second stirring shaft 10, and a reverse transmission sleeve 15 mounted on the second stirring shaft 10 above the lower bevel gear 14. An upper bevel gear 16, symmetrically arranged with the lower bevel gear 14, is located at the bottom end of the reverse transmission sleeve 15, and a fixing seat for fixing the lower impeller 13 is located at the top end of the reverse transmission sleeve 15. A C-shaped connecting sleeve is provided between the reverse transmission sleeve 15 and the second stirring shaft 10, and a transversely arranged intermediate bevel gear 17 is rotatably mounted in the middle of the connecting sleeve. The upper bevel gear 16 and the lower bevel gear 14 are both meshed with the intermediate bevel gear 17. A protective shell 18 is provided on the second stirring shaft 10 at a position corresponding to the connecting sleeve, and the connecting sleeve, upper bevel gear 16, lower bevel gear 14, and intermediate bevel gear 17 are all housed within the protective shell 18. The protective shell 18 is fixedly mounted on the bottom surface of the mixing tank 2. Multiple ultrasonic transducers 19 are provided on the bottom surface of the top cover 5. All ultrasonic... The wave transducer 19 is arranged in a ring on the outer circumference of the first stirring shaft 7; the lifting device includes two lifting frames 20 symmetrically arranged on both sides of the mixing tank 2, and a ball screw 21 is provided on the side of each lifting frame 20 away from the mixing tank 2; a servo motor 22 is connected to the end of the ball screw 21, and a sliding seat is slidably installed on the ball screw 21, and a lifting seat 23 is installed between the top surfaces of the two sliding seats; the medium-speed motor 6 is fixedly installed on the bottom surface of the lifting seat 23; a plurality of support columns 24 are arranged in a ring evenly distributed on the outer circumference of the medium-speed motor 6 on the bottom surface of the lifting seat 23, and the bottom surface of each support column 24 is fixedly connected to the top surface of the top cover 5; a feed gear pump 25 is installed on the feed pipe 3; a discharge gear pump 26 is installed on the discharge pipe 4; a controller 27 is provided on the side of the frame 1, and the lifting device, the medium-speed motor 6, the low-speed motor 11, the feed gear pump 25 and the discharge gear pump 26 are all electrically connected to the controller 27.
[0022] Working Principle: During the mixing process, the entire device is first placed on a horizontal surface and connected to an external safe mains power supply. Then, the raw materials for the water-based ceramic coating to be mixed are added to the mixing tank 2. Next, the controller 27 controls the servo motor 22 to start forward for a certain period. After starting, the servo motor 22 drives the ball screw 21 to rotate. The rotation of the ball screw 21 creates a motion transition with the sliding seat, allowing the sliding seat to move along the ball screw 21 towards the frame 1. During this movement, the sliding seat drives the lifting seat 23 to move as well. The movement of the lifting seat 23 then drives the medium-speed motor 6, the top cover 5, and the first mixing shaft 7. The three-bladed propeller 8 and the serrated disc 9 move, eventually causing the first stirring shaft 7, the three-bladed propeller 8, and the serrated disc 9 to enter the mixing tank 2. At the same time, the top cover 5 covers the opening on the top surface of the mixing tank 2. When the top cover 5 completely covers the top surface of the mixing tank 2, the start time of the servo motor 22 is reached, and the controller 27 controls the servo motor 22 to stop. When the top cover 5 completely covers the top surface of the mixing tank 2, that is, when the first stirring shaft 7 is completely inside the mixing tank 2, there is still a certain distance between the bottom end of the first stirring shaft 7 and the top end of the second stirring shaft 10. This distance is sufficient for the three-bladed propeller 8 and the upper blade 12 to work stably without affecting each other.
[0023] Next, controller 27 starts the medium-speed motor 6, low-speed motor 11, and ultrasonic transducer 19. After the low-speed motor 11 starts, the second stirring shaft 10 rotates. The rotation of the second stirring shaft 10 drives the upper impeller 12 and the lower bevel gear 14 to rotate. The rotation of the lower bevel gear 14 meshes with the middle bevel gear 17, causing the middle bevel gear 17 to rotate. The rotation of the middle bevel gear 17 then meshes with the upper bevel gear 16, causing the upper bevel gear 16 to rotate. The rotation of the upper bevel gear 16 drives... The rotating reverse drive sleeve 15 causes the lower impeller 13 mounted on it to rotate. Simultaneously, because the upper bevel gear 16 and lower bevel gear 14 are symmetrically arranged, the rotation direction of the upper bevel gear 16 is exactly opposite to that of the lower bevel gear 14. This, in turn, causes the upper impeller 12 and lower impeller 13 to rotate in opposite directions. The opposing rotation of the upper and lower impellers 12 and 13 enhances the axial flow of the raw material at the bottom of the mixing tank 2, enabling preliminary mixing of the raw material in the lower middle region of the mixing tank 2. At the same time, it avoids the phenomenon of raw material accumulation dead corners and ensures a certain mixing effect; after the medium-speed motor 6 starts, it drives the first stirring shaft 7 to rotate. The rotation of the first stirring shaft 7 drives the three-bladed propeller 8 and the toothed disc 9 to rotate synchronously. The three-bladed propeller 8 generates a radial and axial composite flow field in the upper middle area of the mixing tank 2 to push the raw materials in the mixing tank 2 to form a vortex. In addition, the toothed disc 9 can apply shear force to the raw materials in the vortex, so that some ceramic powder agglomerates are dispersed, avoiding the final water-based ceramic coating The material contains lumpy raw materials; after the ultrasonic transducer 19 is started, it emits ultrasonic waves into the stirring tube 2. Utilizing the cavitation effect of ultrasonic waves, it can not only further crush the agglomerates in the raw materials, but also promote the adsorption of surfactants on the surface of the dispersed raw materials, thereby improving the stability after dispersion. By using the medium-speed rotating three-bladed propeller 8 and serrated disk 9, the low-speed rotating lower blade 13 and upper blade 12, and the ultrasonic transducer 19, a multi-level stirring effect is formed in the stirring tank 2, which improves the stirring effect and speeds up the stirring rate.
[0024] When the mixing process requires material feeding, the discharge gear pump 26 is started by the controller 27. The discharge gear pump 26 then pumps the water-based ceramic coating from the mixing tank 2 through the discharge pipe 4 to the next process or storage device. Simultaneously, if additional auxiliary materials need to be added during the mixing process, they can be fed into the mixing tank 2 through the feed pipe 3 and by starting the feed gear pump 25. When cleaning is required inside the mixing tank 2, the three-bladed propeller 8, the serrated disc 9, the lower blade 13, and the upper blade 12, the controller 27 first controls and ensures that the medium-speed motor 6 and the low-speed motor 11 are both stopped. Then, the controller 27... The servo motor 22 is controlled to start in reverse. After the servo motor 22 starts in reverse, it will drive the ball screw 21 to rotate in reverse, thereby causing the sliding seat to move the lifting seat 23 upward. During the movement of the lifting seat 23, it will drive the medium speed motor 6, the top cover 5, the first stirring shaft 7, the three-bladed propeller 8 and the sawtooth disc 9 to move together, so that the three-bladed propeller 8 and the sawtooth disc 9 move from inside the mixing tank 2 to directly above the mixing tank 2. Then the servo motor 22 is controlled to stop, and then the mixing tank 2, the three-bladed propeller 8, the sawtooth disc 9, the lower blade 13 and the upper blade 12 can be cleaned. The wastewater generated during the cleaning of the mixing tank 2 can be discharged from the discharge pipe 4 by starting the discharge gear pump 26.
[0025] The controller 27 used in this application can be a programmable controller of model FX2C-20MRD, Cortex-R8, or Cortex-M7; the ultrasonic transducer 19 can be a model of TGM-S, SCIENTZ-650E, or YP-3820-4BZ; the speed of the medium-speed motor 6 is between 300 r / min and 800 r / min; and the speed of the low-speed motor 11 is between 20 r / min and 50 r / min.
