Description

Technical Field

[0001] This invention relates to the field of fire-retardant coating production technology, and in particular to a mixing device for fire-retardant coatings containing bromine-based synergistic flame retardants. Background Technology

[0002] Bromine-based synergistic flame retardant fire-retardant coatings are a type of functional coating that uses bromine-based flame retardants as the core and significantly improves fire resistance through synergistic effects with other flame-retardant components. The core principle is to utilize the "synergistic effect" of different flame-retardant elements to compensate for the shortcomings of a single bromine-based flame retardant, achieving efficient, low-smoke, and environmentally friendly fire protection. During the production and processing of fire-retardant coatings, various flame-retardant components and other additives need to be added to the prepared resin and mixed at high speed. Traditional mixing devices use high-speed rotation of a stirring rod for stirring and dispersion, but this method has poor dispersion and mixing effects, weak shear force, and requires a long stirring and rotation time to achieve the desired effect, slowing down the overall production speed and efficiency. Furthermore, the dispersed coating has a high viscosity, making it difficult and slow to discharge, thus affecting processing speed and efficiency. Summary of the Invention

[0028] The specific usage and function of this embodiment: When mixing the coating, the material is fed into the mixing tank 102 through the feeding pipe 3061. The material inside is stirred by the stirring rod 402. During its rotation, the linkage rod 407 can be controlled to rotate by the pulley A405 on the surface and the transmission belt 406. When the linkage rod 407 rotates, since multiple sets of auxiliary control rods 4093 at the bottom of the linkage rod 407 are inserted into the insertion hole 207, the top connecting plate 206 is controlled to rotate, which drives the bottom control rod 205 to rotate. The gear on the surface of the control lever 205 meshes with the drive gear ring 202, causing the rotating support ring 201 and inner rotating ring 203 to rotate. The internal stirring rod A204 rotates to assist in stirring. Since the stirring rod B404 rotates in the opposite direction to the stirring rod A204, the two stirring methods can provide excellent shear force, accelerate stirring, and improve the stirring effect. When stirring is complete and discharge is required, the hydraulic control lever A305 can be activated, pushing the bottom drive ring 303 and the sealing plate 304 downwards. The sealing plate 304 moves downwards, and the bottom and top retaining ring 10... 4. The fixed retaining ring 403 is in contact with the container, and sealing rubber gaskets are provided on the contact surfaces to provide auxiliary sealing at the contact points. The downward movement of the sealing pressure plate 304 is also controlled by the bracket 3062 and the connecting rod 3063 to move the top sealing cover 3064 downward. The top sealing cover 3064 covers the inlet of the feeding pipe 3061, sealing off the upper part of the carrying mixing tank 102. Subsequently, the hydraulic control rod 502 is activated, and the sliding push plate 504 is pushed to inject gas from the air cylinder 503 into the carrying mixing tank 102 through the air pipe 302 and the connecting pipe 505. The increased air pressure inside the mixing tank 102 helps to push the coating material inside the mixing tank 102 outward, increasing the discharge speed. The top cover 301 and the mixing tank 102 can be separated to facilitate cleaning of the inside of the mixing tank 102. When reinstalling, the docking component 409 can be directly inserted into the auxiliary insertion tube 208. If the auxiliary control rod 4093 is not inserted into the insertion hole 207, when the mixing starts, the control rod 4093 will be pushed by the elastic force of the spring 4094 and can automatically insert into the insertion hole 207 during rotation, completing the docking.
