Master-batch drying device

Abstract

The invention discloses a master-batch drying device. The master-batch drying device comprises a drying barrel, wherein a stirring paddle is vertically arranged in the drying barrel; a barrel cover is arranged at the upper part of the drying barrel; a motor is fixedly arranged on the barrel cover of the drying barrel, and is connected with the stirring paddle by a speed reducer; the lower part of the drying barrel is connected with a conical filter mesh; the side wall of the lower part of the conical filter mesh is connected with an air channel which is internally provided with a heating pipe; an exhaust port is formed in the barrel cover; a discharging port of the bottom part of the conical filter mesh is provided with a sieve mesh; the stirring paddle extends to the interior of the conical filter mesh; and multiple layers of stirring blades are distributed on the stirring paddle. The master-batch drying device has the characteristics that the stirring paddle is arranged in the drying barrel and the conical filter mesh, the stirring blades on the stirring paddle are divided into an upper group, a middle group and a lower group, and the two-layer stirring blades in the conical filter mesh can enhance vertical and lateral flowing of the master batches in the filter mesh so as to guarantee the drying quality of the master batches.

Description

technical field [0001] The invention relates to a drying equipment for color masterbatches, in particular to a drying device used in the drying and dispersing process of small batches of color masterbatches. Background technique [0002] In the production process of colored silk, the drying and screening process of the masterbatch is the key process. The main task is to disperse and screen the masterbatch evenly after drying, and then inject it into the screw quantitatively through the syringe, and heat and extrude the melt together with the slices. Spun into colored polyester filaments. If the dry quality and uneven dispersion of the masterbatch do not meet the production requirements, it will have a great impact on the production of colored silk. In severe cases, a large number of products will be scrapped due to color difference or small coils will be broken, resulting in increased consumption. . [0003] In order to meet this requirement, the general color silk factory...

Problems solved by technology

Disadvantages of this method: 1. It is easy to cause uneven heating and drying of the upper and lower color masterbatches in the barrel, and the moisture content is unstable

2. Uneven upper and lower temperature, easy to cause color masterbatch agglomeration

3. After drying, the color masterbatch needs to be manually ground and screened, whic
