Description

Technical Field

[0001] This utility model relates to the technical field of nano-coating production equipment, and in particular to an energy-saving mixing equipment for producing self-cleaning heat-reflective nano-coatings. Background Technology

[0002] Self-cleaning heat-reflective nano-coatings are high-performance coatings that integrate self-cleaning and heat insulation / cooling functions. They are widely used in the construction and automotive industries. In their production process, mixing equipment plays a crucial role. It is necessary to fully and uniformly mix nano-sized powders, functional additives, and liquid resin raw materials while meeting energy-saving requirements. An efficient energy-saving mixing equipment for the production of self-cleaning heat-reflective nano-coatings should not only achieve uniform dispersion of materials but also reduce energy consumption and energy waste in the production process, thereby improving production efficiency and economic benefits.

[0003] Early mixing equipment consisted of a stirring motor, stirring shaft, and simple blades, with a single stirring method. Due to the simple blade structure, fluid flow dead zones easily appeared inside the equipment during the stirring process, causing a large amount of material to accumulate in the corners or bottom of the tank and fail to mix fully, seriously affecting the quality of the coating. With the development of technology, existing mixing equipment adopts a dual-shaft stirring and spiral flow guiding structure, which has improved the mixing effect to some extent. However, even with the adoption of a complex stirring structure, existing equipment still has the problem of mixing dead zones. Existing equipment uses multi-axis rotation in different directions to drive the material to form a circulation flow in the tank, attempting to avoid local incomplete mixing. However, due to the gap between the stirring blades and the tank wall, and the relatively fixed trajectory of the blades, the fluid velocity is low in the edge and bottom areas of the tank, making it difficult for the material to form effective convection. As a result, some areas of nanoparticles and additives cannot fully contact the main material, ultimately forming mixing dead zones, resulting in uneven mixing of the coating and affecting the stability of product performance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an energy-saving mixing device for the production of self-cleaning heat-reflective nano-coatings, which aims to improve the problem in the prior art where the fluid flow rate is low in the tank edge and bottom areas, making it difficult for materials to form effective convection.

The outer walls of the sliders are slidably connected to the inner wall of the conductor ring. A hollow support plate is fixedly connected to the middle of the outer wall of the mixing tank. A magnetic ring is rotatably connected to the inner wall of the hollow support plate. An oscillating assembly is provided on the front side of the top of the hollow support plate.

[0010] The drive assembly includes a DC motor, the bottom end of which is fixedly connected to the front top of the top cover, and a bevel gear is fixedly connected to the output end of the DC motor. Hollow bevel gears are also fixedly connected to the top ends of the hollow cylinder and the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The swing assembly includes a hollow frame plate. The outer wall of the hollow frame plate is slidably connected to the front top of the hollow support plate. Racks are fixedly connected to both the front and rear sides of the inner wall of the hollow frame plate. A servo motor is fixedly connected to the front end of the bottom side of the inner wall of the hollow support plate. The output end of the servo motor passes through the bottom end of the hollow support plate and is fixedly connected to a non-circular gear. L-shaped columns are rotatably connected to the left and right sides of the top of the magnetic ring. The outer walls of the two L-shaped columns are slidably connected to the left and right sides of the outer wall of the hollow frame plate, respectively.

[0013] As a further description of the above technical solution:

[0014] The discharge assembly includes an L-shaped discharge pipe, the top of which is connected to the middle of the bottom of the mixing tank, and a pipe valve is fixedly connected to the outer wall of the L-shaped discharge pipe.

[0015] As a further description of the above technical solution:

[0016] The feeding assembly includes a feed pipe, the bottom end of which is connected to the top left side of the top cover, and a flange is fixedly connected to the top end of the feed pipe.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a DC motor is started to drive the bevel gear to rotate. Because the bevel gear meshes with the hollow cylinder and the hollow bevel gear at the top of the rotating shaft, the hollow cylinder and the rotating shaft rotate in opposite directions. Then, the hollow cylinder and the rotating shaft drive the rotating disks on their respective outer walls to rotate. The inclined push plate fixed on the rotating disk moves accordingly, pushing the solution up and down in the stirring tank. The baffle enhances the disturbance to the solution, thereby causing the solution to initially mix by impact.

[0023] 2. In this utility model, the servo motor drives the irregular gear to rotate, causing the hollow frame plate to slide left and right at the top of the hollow support plate. The L-shaped column auxiliary magnetic ring reciprocates along with the hollow frame plate on the inner wall of the hollow support plate. Since the magnetic ring and the conductor ring transmit power and torque through magnetic eddy current, the conductor ring will reciprocate along with the magnetic ring. When the conductor ring rotates, the slider that is slidably connected to its inner wall drives the guide plate to swing. The swing of the guide plate causes the solution after collision to change its flow direction under its guidance, thereby enhancing the solution mixing effect. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides an energy-saving mixing device for producing self-cleaning heat-reflective nano-coatings, including a support frame 1, a mixing tank 4, and a top cover 5. The inner wall of the top cover 5 is provided with an up-and-down mixing mechanism 2, and the inner wall of the mixing tank 4 is provided with a swinging mechanism 3 for swinging the liquid up and down. The bottom end of the mixing tank 4 is provided with a discharge component 6, and the top left side of the top of the top cover 5 is provided with a feeding component 7 for feeding. The feeding component 7 first conveys the raw materials of the self-cleaning heat-reflective nano-coatings into the mixing tank 4. The right side of the outer wall of the mixing tank 4 is provided with an observation component 8.

[0033] The upper and lower mixing mechanism 2 includes a hollow cylinder 201. The outer wall of the hollow cylinder 201 is rotatably connected to the inner wall of the top cover 5. A rotating shaft 202 is rotatably connected to the inner wall of the hollow cylinder 201. A rotating disk 203 is fixedly connected to the outer walls of both the hollow cylinder 201 and the rotating shaft 202. Multiple inclined push plates 204 are fixedly connected to the outer wall of the rotating disk 203. A DC motor 2061 is started, and its output end drives a bevel gear 2062 to rotate. Due to the hollow space between the bevel gear 2062 and the top of the hollow cylinder 201 and the rotating shaft 202... The bevel gear 2063 meshes, causing the hollow cylinder 201 and the rotating shaft 202 to rotate in different directions. The hollow cylinder 201 and the rotating shaft 202 drive the rotating disk 203 on their respective outer walls to rotate, and the inclined push plate 204 fixed on the rotating disk 203 moves accordingly. The inclined push plate 204 pushes the solution to move up and down in the stirring tank 4. A baffle 205 is fixedly connected to the inner wall of the inclined push plate 204. The baffle 205 further enhances the disturbance to the solution. A drive assembly 206 is provided at the top of the top cover 5.

[0034] The drive assembly 206 includes a DC motor 2061, the bottom end of which is fixedly connected to the front top of the top cover 5. A bevel gear 2062 is fixedly connected to the output end of the DC motor 2061. Hollow bevel gears 2063 are fixedly connected to the top ends of both the hollow cylinder 201 and the rotating shaft 202. The upper and lower sides of the outer wall of the bevel gear 2062 mesh with the inner walls of the corresponding hollow bevel gears 2063. The inner wall size of the hollow cylinder 201 is the same as the outer wall size of the rotating shaft 202. When the DC motor 2061 starts, its output end drives the bevel gear 2062 to rotate. Since the bevel gear 2062 meshes with the hollow bevel gears 2063 at the top of the hollow cylinder 201 and the rotating shaft 202, the hollow cylinder 201 and the rotating shaft 202 rotate in different directions.

[0035] Specifically, the feeding component 7 first delivers the raw materials of the self-cleaning heat-reflective nano-coating into the mixing tank 4. At this time, the drive component 206 starts to operate, and the DC motor 2061 starts. Its output end drives the bevel gear 2062 to rotate. Since the bevel gear 2062 meshes with the hollow cylinder 201 and the hollow bevel gear 2063 at the top of the rotating shaft 202, the hollow cylinder 201 and the rotating shaft 202 rotate in different directions. The hollow cylinder 201 and the rotating shaft 202 drive the rotating disk 203 on their respective outer walls to rotate, and the inclined push plate 204 fixed on the rotating disk 203 moves accordingly. The inclined push plate 204 pushes the solution to move up and down in the mixing tank 4. The baffle 205 further enhances the disturbance to the solution, realizing the initial up and down impact and mixing together.

[0036] Reference Figure 1 , Figure 3 and Figure 5The oscillating mechanism 3 includes multiple guide plates 301, the outer walls of which are rotatably connected to the upper side of the inner wall of the mixing tank 4. A conductor ring 303 is rotatably connected to the middle of the inner wall of the mixing tank 4. A slider 302 is rotatably connected to the bottom of the outer wall of the guide plates 301. The outer walls of the sliders 302 are slidably connected to the inner wall of the conductor ring 303. A hollow support plate 305 is fixedly connected to the middle of the outer wall of the mixing tank 4. A magnetic ring 304 is rotatably connected to the inner wall of the hollow support plate 305. An oscillating assembly 306 is provided on the front side of the top of the hollow support plate 305. Since the magnetic ring 304 and the conductor ring 303 transmit power and torque through magnetic eddy currents, the conductor ring 303 will rotate with the reciprocating rotation of the magnetic ring 304. When the conductor ring 303 rotates, the sliders 302 slidably connected to its inner wall drive the guide plates 301 to oscillate. The oscillating assembly 306 includes a hollow frame plate 3061. The outer wall of plate 3061 is slidably connected to the front top of hollow support plate 305. The inner wall of hollow frame plate 3061 is fixedly connected to both the front and rear sides with racks 3062. The bottom front end of the inner wall of hollow support plate 305 is fixedly connected to a servo motor 3065. The output end of the servo motor 3065 passes through the bottom end of hollow support plate 305 and is fixedly connected to a special-shaped gear 3063. The top left and right sides of magnetic ring 304 are rotatably connected to L-shaped columns 3064. The outer walls of the two L-shaped columns 3064 are slidably connected to the left and right sides of the outer wall of hollow frame plate 3061 respectively. When the servo motor 3065 in the swing assembly 306 is started, it drives the special-shaped gear 3063 to rotate. The special-shaped gear 3063 meshes with the rack 3062 in hollow frame plate 3061, so that hollow frame plate 3061 slides left and right at the top of hollow support plate 305, so that L-shaped columns 3064 assist magnetic ring 304 in reciprocating rotation.

[0037] Specifically, the servo motor 3065 in the swing assembly 306 is activated, which in turn drives the irregular gear 3063 to rotate. The irregular gear 3063 meshes with the rack 3062 inside the hollow frame plate 3061, causing the hollow frame plate 3061 to slide left and right at the top of the hollow support plate 305. This causes the L-shaped column 3064 to assist the magnetic ring 304 in reciprocating rotation, which in turn reciprocates along with the sliding of the hollow frame plate 3061 on the inner wall of the hollow support plate 305. Since the magnetic ring 304 and the conductor ring 303 transmit power and torque through magnetic eddy currents, the conductor ring 303 will rotate with the reciprocating rotation of the magnetic ring 304. When the conductor ring 303 rotates, the slider 302, which is slidably connected to its inner wall, drives the guide plate 301 to swing. The swing of the guide plate 301 causes the solution after collision to change its flow direction by going up and down under its guidance, thereby further enhancing the mixing effect of the solution.

[0038] Reference Figure 1 , Figure 2 and Figure 3The discharge assembly 6 includes an L-shaped pipe 601, the top of which is connected to the middle of the bottom of the mixing tank 4. A pipe valve 602 is fixedly connected to the outer wall of the L-shaped pipe 601. The coating is discharged through the L-shaped pipe 601, and the discharge of the coating can be controlled by the pipe valve 602. The feeding assembly 7 includes a feed pipe 701, the bottom of which is connected to the left side of the top of the top cover 5. A flange 702 is fixedly connected to the top of the feed pipe 701. The feed pipe 701 can easily add raw materials to the mixing tank 4, and the flange 702 can easily connect to other pipes. The observation assembly 8 includes a high-pressure window 801, the outer wall of which is fixedly connected to the right side of the outer wall of the mixing tank 4. A sealing sleeve 802 is fixedly connected to the outer wall of the high-pressure window 801. The high-pressure window 801 can easily observe the mixing situation during equipment mixing, and the sealing sleeve 802 can prevent leakage at the edge of the high-pressure window 801.

[0039] Specifically, after mixing is complete, the coating is discharged through the L-shaped drain pipe 601, and the discharge of the coating can be controlled by the pipe valve 602. The feed pipe 701 facilitates the addition of raw materials to the mixing tank 4, and the flange 702 facilitates connection with other pipes. The high-pressure window 801 facilitates the observation of the mixing situation during equipment mixing, and the sealing sleeve 802 prevents leakage at the edge of the high-pressure window 801.

[0040] Working principle: First, when the equipment is started, the feeding component 7 first delivers the raw materials of the self-cleaning heat-reflective nano-coating into the mixing tank 4. At this time, the drive component 206 starts to run, and the DC motor 2061 starts. Its output end drives the bevel gear 2062 to rotate. Because the bevel gear 2062 meshes with the hollow cylinder 201 and the hollow bevel gear 2063 at the top of the rotating shaft 202, the hollow cylinder 201 and the rotating shaft 202 rotate in different directions. The hollow cylinder 201 and the rotating shaft 202 drive the rotating disk 203 on their respective outer walls to rotate. The inclined push plate 204 fixed on the rotating disk 203 moves accordingly. The inclined push plate 204 pushes the solution in the mixing tank 4 to move up and down. The baffle 205 further enhances the disturbance effect on the solution, realizing the initial up and down impact, so that the solution is mixed together.

[0041] Furthermore, the servo motor 3065 in the swing assembly 306 is activated by the swing mechanism 3, which drives the irregular gear 3063 to rotate. The irregular gear 3063 meshes with the rack 3062 inside the hollow frame plate 3061, causing the hollow frame plate 3061 to slide left and right at the top of the hollow support plate 305. The L-shaped column 3064 assists the magnetic ring 304 to reciprocate. The magnetic ring 304 reciprocates along the inner wall of the hollow support plate 305 as the hollow frame plate 3061 slides. Since the magnetic ring 304 and the conductor ring 303 transmit power and torque through magnetic eddy currents, the conductor ring 303 will rotate with the reciprocating rotation of the magnetic ring 304. When the conductor ring 303 rotates, the slider 302, which is slidably connected to the inner wall of the conductor ring 303, drives the guide plate 301 to swing. The swing of the guide plate 301 causes the solution after collision to change its flow direction up and down under its guidance, thereby further enhancing the mixing effect of the solution.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
