Description

Technical Field

[0001] This utility model relates to the technical field of graphene coating processing equipment, and in particular to a graphene powder screening device. Background Technology

[0002] Graphene coatings are a new type of coating based on graphene materials, possessing excellent physical, chemical, and mechanical properties. Graphene general anti-corrosion coatings (primers) are mainly used in shipbuilding, bridges, ports, petroleum, and chemical industries for surface protection of substrates requiring acid and alkali resistance in atmospheric environments, such as containers, pipelines, concrete surfaces, and factory buildings. They are used in conjunction with graphene general anti-corrosion coatings. They exhibit good adhesion to steel and concrete surfaces; the film-forming material is chemically inert, has good sealing properties, good outdoor weather resistance, and excellent chemical resistance.

[0003] Graphene coatings are generally composed of graphene powder, resin, oil, or emulsion as the main components, along with pigments, fillers, and appropriate additives, and are prepared into a viscous liquid using organic solvents or water. Graphene powder needs to be filtered and sieved during use to remove impurities. Currently, sieving is generally done using flat sieves. However, the sieving method of flat sieves is singular and not conducive to material dispersion, resulting in poor sieving efficiency. Utility Model Content

The support partition 8 extends from the opening 406 into the protective cover 405. The protective cover 405 is slidably connected to the support partition 8.

[0022] Specifically, the side of the supporting partition 8 is provided with an annular groove 801, and the bottom of the protective cover 405 is provided with a limiting slider 407 that cooperates with the groove 801. In this embodiment, both sides of the supporting partition 8 are provided with grooves 801, and both sides of the opening 406 are provided with sliders that cooperate with the grooves 801, thereby improving the stability of the protective cover 405.

[0023] To improve the stability of the screen cylinder 4 during rotation, in a further embodiment, a base 201 is fixedly connected to the bottom of the feed pipe 2, and a support 202 corresponding to the screen cylinder 4 is provided on the base 201. The screen cylinder 4 is rotatably connected to the support 202. A discharge pipe 203 communicating with the inside of the feed pipe 2 is fixedly provided at the bottom of the feed pipe 2. The discharge pipe 203 extends into the screen cylinder 4 and is rotatably connected to it.

[0024] To prevent materials from scattering outwards, in a further embodiment, the two ends of the screen cylinder 4 are coaxially connected to baffle plates 402 arranged around it.

[0025] To improve the stability of the screening cylinder 4 during its revolution, in a further embodiment, an annular rotating seat 101 is rotatably connected to the inner wall of the tank body 1, and a discharge box 403 is rotatably connected to the end of the screening cylinder 4 away from the feed pipe 2. The bottom of the discharge box 403 is provided with a discharge port 404 facing the fine material collection chamber 6, and the discharge box 403 is fixedly connected to the rotating seat 101.
