Description

Technical Field

[0001] This utility model belongs to the technical field of coating preparation equipment, specifically relating to a nano-modified high weather-resistant exterior wall coating preparation device. Background Technology

[0002] The nano-modified high-weather-resistant exterior wall coating preparation device is a specialized equipment system for producing nano-composite exterior wall coatings with excellent weather resistance properties (such as UV resistance, acid and alkali resistance, and pollution resistance). This type of device uniformly disperses nanomaterials (such as nano-TiO2 and nano-SiO2) into the coating matrix and utilizes specific processes (such as ultrasonic dispersion, ball milling, and in-situ polymerization) to achieve stable composite formation of nanoparticles, thereby improving the coating's aging resistance, self-cleaning properties, and mechanical strength.

[0003] Currently, the preparation of nano-modified high weather-resistant exterior wall coatings requires the use of reaction vessels for stirring and mixing. Generally, the well-dispersed nano-slurry is mixed with acrylic emulsions, silicone-acrylic emulsions, etc., and additives are added. However, the existing nano-modified high weather-resistant exterior wall coating preparation devices have the following drawbacks during use: In the production of nano-modified high weather-resistant coatings, nanomaterials are prone to agglomeration, and if additives are added directly and in a concentrated manner, they may not be fully dispersed. Furthermore, stirring can only be carried out in the horizontal direction, which affects the final coating performance and mixing effect. Therefore, a nano-modified high weather-resistant exterior wall coating preparation device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a nano-modified high weather-resistant exterior wall coating preparation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nano-modified high weather-resistant exterior wall coating preparation device, comprising a reaction tank, a discharge pipe with an electric valve fixedly connected to the bottom outlet of the reaction tank, a stirring shaft movably inserted into a perforation at the center of the top of the reaction tank, the top of the stirring shaft fixedly connected to the output shaft of a motor, a fixed square tube fixedly connected to a feed square inlet at the edge of the top of the reaction tank, a movable square tube sliding inside the fixed square tube, a feeding hopper fixedly connected to the top of the movable square tube, the inner bottom walls of the movable square tube and the fixed square tube being inclined and closed, and a second discharge port and a first discharge port respectively opened on the side wall of the movable square tube and the fixed square tube facing the stirring shaft;

[0006] A reciprocating lifting transmission assembly is installed at the top of the reaction vessel and is also connected to the two side walls of the motor and the outer wall of the feeding hopper.

[0007] In a preferred embodiment, the size of the second discharge port matches the size of the first discharge port.

[0008] In a preferred embodiment, the reciprocating lifting transmission assembly includes an inverted L-shaped lifting plate fixedly connected to both sides of the motor. A fixed outer plate is slidably sleeved on the outer side of each inverted L-shaped lifting plate. The cross-section of the fixed outer plate is U-shaped. The bottom end of the fixed outer plate is fixedly connected to the top of the reaction vessel.

[0009] In a preferred embodiment, a transmission column is fixedly connected to both side walls of the two inverted L-shaped lifting plates. A transmission plate is movably sleeved on the outer side of each transmission column. A transmission channel that cooperates with the transmission column is opened on each transmission plate. The transmission channel is inclined and the inner width of the transmission channel is equal to the diameter of the transmission column.

[0010] In a preferred embodiment, the bottom ends of the two transmission plates are fixedly connected to the same U-shaped moving plate. The bottom end of the U-shaped moving plate is slidably sleeved on the outside of two symmetrically arranged guide rails. The vertical cross-section of the guide rails is T-shaped. The guide rails are all fixedly connected to the top of the reaction vessel. The top of the guide rails is fixedly connected to an electric telescopic rod. The telescopic ends of the electric telescopic rods are all fixedly connected to the U-shaped moving plate.

[0011] In a preferred embodiment, a connecting plate is provided above the U-shaped moving plate, which is fixed between the motor and the feeding hopper.

[0012] Compared with the prior art, the nano-modified high weather-resistant exterior wall coating preparation device provided by this utility model has at least the following beneficial effects:

[0013] In this invention, when using the nano-modified high weather-resistant exterior wall coating preparation device, by activating two electric telescopic rods and pulling the U-shaped moving plate towards the two electric telescopic rods, and with the help of the transmission plate and transmission column, the motor can be lowered via the inverted L-shaped lifting plate and the fixed outer plate, driving the stirring shaft to descend. Then, the two electric telescopic rods push the U-shaped moving plate away from the electric telescopic rods, causing the motor to drive the driven stirring shaft to rise again. Thus, the stirring shaft can perform a reciprocating lifting motion while stirring and rotating. In addition, during the reciprocating lifting motion, the connecting plate drives the movable square tube connected to the bottom of the feeding hopper to perform a reciprocating lifting motion. Therefore, when the second discharge port coincides with the first discharge port, the additives in the feeding hopper can intermittently fall into the reaction tank, achieving a thorough dispersion effect. Combined with the reciprocating lifting motion, the performance and mixing effect of the final coating are greatly improved. Attached Figure Description

[0022] Example

[0023] Currently, in the preparation of nano-modified high weather-resistant exterior wall coatings, a reaction vessel 1 is required for stirring and mixing. Generally, the well-dispersed nano-slurry is mixed with acrylic emulsion, silicone acrylic emulsion, etc., and additives are added. However, the existing nano-modified high weather-resistant exterior wall coating preparation device has the following disadvantages in use: In the production of nano-modified high weather-resistant coatings, nanomaterials are prone to agglomeration. If the additives are added directly and in a concentrated manner, they may not be fully dispersed. At the same time, stirring can only be achieved in the horizontal direction, which affects the performance of the final coating and the mixing effect.

[0024] For this purpose, please refer to Figure 1-4 This utility model provides a nano-modified high weather-resistant exterior wall coating preparation device, comprising: a reaction tank 1, a discharge pipe 11 with an electric valve fixedly connected to the discharge port at the bottom end of the reaction tank 1, a stirring shaft 21 movably inserted into a perforation at the center of the top end of the reaction tank 1, the top end of the stirring shaft 21 being fixedly connected to the output shaft of a motor 2, a fixed square tube 12 fixedly connected to a feed square port at the edge of the top end of the reaction tank 1, a movable square tube 13 slidingly connected to the inner side of the fixed square tube 12, a feeding hopper 14 fixedly connected to the top end of the movable square tube 13, the inner bottom walls of the movable square tube 13 and the fixed square tube 12 being inclined and closed, and a second discharge port 131 and a first discharge port 121 respectively opened on the side wall of the movable square tube 13 and the fixed square tube 12 facing the stirring shaft 21; and a reciprocating lifting transmission assembly 3, which is installed at the top end of the reaction tank 1 and is also connected to the two side walls of the motor 2 and the outer wall of the feeding hopper 14.

[0025] At this time, the bottom end of the stirring shaft 21 is at a certain height from the inner bottom wall of the reaction vessel 1;

[0026] The inner bottom walls of both the movable square tube 13 and the fixed square tube 12 are inclined and closed to facilitate the intermittent sliding of the additive powder down the inclined surface into the reaction vessel 1.

[0027] Further as Figure 1-4 As shown, it is worth noting that the size of the second discharge port 131 matches the size of the first discharge port 121.

[0028] Further as Figure 1-4As shown, it is worth noting that in order to enable the motor 2 to drive the stirring shaft 21 to perform reciprocating lifting motion, and simultaneously enable the feeding hopper 14 to perform up-and-down lifting motion, so that the additives can fall intermittently into the reaction tank 1, a reciprocating lifting transmission assembly 3 is provided. This assembly includes inverted L-shaped lifting plates 31 fixed to both sides of the motor 2. A fixed outer plate 32 is slidably fitted on the outer side of each inverted L-shaped lifting plate 31. The fixed outer plate 32 has an open cross-section, and its bottom end is fixed to the top of the reaction tank 1. A transmission column 33 is fixed to both sides of the two inverted L-shaped lifting plates 31, and a transmission column 33 is movably fitted on the outer side of each transmission column 33. Both the moving plate 34 and the transmission plate 34 are provided with transmission channels that cooperate with the transmission column 33. The transmission channels are inclined and the inner width of the transmission channels is equal to the diameter of the transmission column 33. The bottom ends of the two transmission plates 34 are fixedly connected to the same U-shaped moving plate 35. The bottom end of the U-shaped moving plate 35 is slidably sleeved on the outside of two symmetrically arranged guide rails 36. The vertical cross section of the guide rails 36 is T-shaped. The guide rails 36 are fixedly connected to the top of the reaction tank 1. The top of the guide rails 36 is fixedly connected to an electric telescopic rod 37. The telescopic ends of the electric telescopic rods 37 are fixedly connected to the U-shaped moving plate 35. Above the U-shaped moving plate 35 is a connecting plate 38 fixed between the motor 2 and the feeding hopper 14.

[0029] Specifically, the inclination angle of the transmission channel is 30 degrees, and the inner width of the transmission channel is equal to the diameter of the transmission column 33 in order to prevent the inverted L-shaped lifting plate 31 from moving up and down.

[0030] In summary: When using this nano-modified high-weather-resistant exterior wall coating preparation device, by activating the two electric telescopic rods 37 and pulling the U-shaped moving plate 35 towards the two electric telescopic rods 37, and in conjunction with the transmission plate 34 and transmission column 33, the motor 2 can be lowered via the inverted L-shaped lifting plate 31 and the fixed outer plate 32, thereby driving the stirring shaft 21 to descend. Then, the two electric telescopic rods 37 push the U-shaped moving plate 35 away from the electric telescopic rods 37, thus causing the motor 2 to drive the stirred shaft 21. The mixing shaft 21 is raised, so that while the mixing shaft 21 is rotating, it can also move back and forth. In addition, while moving back and forth, the connecting plate 38 drives the movable square tube 13 connected to the bottom of the feeding hopper 14 to move back and forth. So when the second discharge port 131 coincides with the first discharge port 121, the additives in the feeding hopper 14 can fall into the reaction tank 1 intermittently to achieve a full dispersion effect. At the same time, the reciprocating lifting action greatly improves the performance and mixing effect of the final coating.
