Description

Technical Field

[0001] The utility model relates to the field of plastic processing, in particular to a masterbatch drying system. Background Art

[0002] Masterbatch, also known as plastic masterbatch, refers to the granular material obtained by mixing and kneading various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then measuring, mixing, melting, extruding, pelletizing and other processing processes such as extruders and other equipment. Before using the masterbatch for related production and processing, it is necessary to ensure that it is dry, so it needs to be dried.

[0003] At present, the Chinese patent with application number CN202222314799.4 discloses a drum-type plastic masterbatch drying device, which generates hot air by starting a hot air blower, and the hot air enters the air supply cavity through the air pipe, and finally sprays out from the air hole to various places in the inner cavity of the cylinder; through the setting of the crushing component, because the plastic masterbatch contains water vapor before drying, some plastic masterbatch agglomerates, and the water vapor inside the agglomerate is not easy to be dried, the crushing component breaks up the agglomerate to facilitate subsequent drying; through the setting of the electric heating wire, the outer wall of the cylinder has heat, making the drying effect stronger; through the setting of the lateral air cylinder, the lateral air cylinder can be connected to various angles of the outer wall of the air guide cylinder, so that the hot air can be sprayed from various angles, thereby increasing the heat in various places in the cylinder. It can make the hot air flow in the vertical direction of the cylinder, thereby increasing the time the hot air stays in the cylinder, increasing the contact time with the plastic masterbatch, and reducing the waste of heat. However, in the drying operation of masterbatches, temperature is a key factor. Too high a temperature may cause the pigment to decompose or oxidize, thereby causing color changes. Different types of masterbatches require different drying temperatures. Therefore, the drying temperature needs to be strictly controlled to ensure that it is within the stable temperature range of the pigment and carrier resin. This equipment cannot adjust the drying temperature according to actual needs and is inconvenient to use.

[0004] Based on this, the utility model designs a masterbatch drying system to solve the above problems. Utility Model Content
