A new material color masterbatch spiral dispersion drying device

Abstract

The invention discloses a screw-type dispersion and drying device for new material color masterbatch. The screw-type dispersion and drying device comprises a drying box; a feed port is fixedly formedin the top end of the drying box; a dispersion device is arranged in a feed cover; a drying device is arranged below the dispersion device and comprises drying pipes; a plurality of hot air pipes arecoaxially arranged in the drying pipes; the bottom ends of the hot air pipes are fixedly connected with hot air spray heads; dense air exhaust holes are formed in the hot air pipes and the hot air spray heads; the hot air pipes are fixedly connected with spiral discharge plates; a plurality of negative pressure branch pipes are arranged on the outer side of each drying pipe; a steel wire mesh bagis arranged below the drying device; two first conveying belts are arranged below discharge plates; a second conveying belt is arranged below an air exhaust plate; and return devices are arranged on the parts, at the two ends of the steel wire mesh bag, of the inner walls of the drying box. The screw-type dispersion and drying device is good in drying effect on color masterbatch and high in dryingspeed, and particularly suitable for drying of color masterbatch in large quantities, and the problem that the drying effect on the large quantities of color masterbatch is not ideal is solved.

Description

technical field [0001] The invention relates to the field of new material preparation, in particular to a screw-type dispersing and drying device for color masterbatches of new materials. Background technique [0002] With the rapid development of science and technology, people have developed new materials based on the research results of modern science and technology on the basis of traditional materials. Masterbatch is a polymer plastic colorant produced by a high proportion of pigments or additives and thermoplastic resins after good dispersion. , plays an important role in the production of plastic products. In the production process of colored filaments, the masterbatch is mainly dried, dispersed and screened evenly, and then injected into the screw, and colored polyester filaments are spun into colored polyester filaments by heating and extrusion. , due to the high moisture content of the color masterbatch, the polymer will be degraded during the high-temperature melti...

Problems solved by technology

[0002] With the rapid development of science and technology, people have developed new materials based on the research results of modern science and technology on the basis of traditional materials. Masterbatch is a polymer plastic colorant produced by a high proportion of pigments or additives and thermoplastic resins after good dispersion. , plays an important role in the production of plastic products. In the production process of colored filaments, the masterbatch is dried, dispersed and screened evenly, then injected into the screw, and colored polyester filaments are spun into colored polyester filaments by heating and extrusion. , due to the high moisture content of the color masterbatch, the polymer will be degraded during the high-temperature melting process, and the polymer macromolecules will be broken, resulting in problems such as high broken ends of polyester filaments, poor spinnability, and low strength of post-processing products. Therefore, The dryness of the masterbatch seriously affects the quality of the colored polyester filament produced

[0003] The existing masterbatch drying device usually uses the circulation of high-temperature gas and the tumbling and stirring of the masterbatch raw material inside the device to dry. This drying method can dry a large amount of masterbatch at one time, but the overall drying method makes the color masterbatch The drying of the masterbatch is not thorough, which greatly affects the drying effect, and when there are many and large water drops on the raw material of the masterbatch, the amount of hot air required is large and the drying time is long, which greatly reduces the drying time.
