Description

Technical Field

[0001] The utility model relates to the technical field of flame retardant processing, and specifically relates to a centrifuge for producing melamine cyanurate flame retardant. Background Art

[0002] Melamine cyanurate is an effective flame retardant widely used in polymer materials such as plastics, rubber and textiles. It releases non-combustible gases such as nitrogen and water vapor, which effectively slows down the burning rate of materials and improves their flame retardant properties. Centrifuges play a key role in the production of melamine cyanurate.

[0003] A Chinese patent discloses a transplanting device for forestry afforestation, with the publication number CN215030116U. The article proposes "a centrifuge for the production of brominated flame retardants with adjustable speed, including a load-bearing plate, a slide plate 1 is arranged above the load-bearing plate, an inner cylinder is fixed on one side of the slide plate 1, a slide plate 2 is arranged above the slide plate 1, an outer cylinder is fixed on one side of the slide plate 2, and a tooth groove is opened on one side of the slide plate 1 and the slide plate 2, and a plurality of tooth rollers are meshed on the inner side of the tooth groove, one end of the tooth roller is located between the slide plate 1 and the slide plate 2, and a protective shell is movably installed on the other end of the tooth roller, one side of the bottom of the protective shell is fixed on the surface of the load-bearing plate, and one side wall of the top of the protective shell is movably installed on the side wall of the outer cylinder. In the utility model, a plurality of tooth rollers drive the slide plate 1 more stably when the double-sided tooth discs are meshed. It moves on the pulley. During processing, the controller can adjust the speed of the inner cylinder through the speed of the servo motor. After processing, the solenoid valve is opened by the controller to discharge the processed brominated flame retardant from the lower hopper for collection. However, the above equipment does not have a shock absorption function in actual use. However, the centrifuge will generate large vibrations when rotating at high speed. If there is no shock absorption function, these vibrations may be transmitted to the supporting structure of the equipment and the surrounding environment, resulting in instability of the equipment and even affecting production efficiency and product quality. At the same time, continuous vibration may cause damage or increased wear of equipment parts, requiring more frequent maintenance and replacement of parts, increasing maintenance costs and downtime, and reducing the reliability and service life of the equipment.
