Small masterbatch drying device

Abstract

The invention relates to the technical field of drying and protecting devices, in particular to a small masterbatch drying device. The small masterbatch drying device comprises a heat-preserving barrel body, wherein a barrel cover is arranged at the upper end of the heat-preserving barrel body; an exhaust port is formed on the barrel cover; a conical barrel is connected to the lower end of the heat-preserving barrel body; a dry and hot air conveying pipe is arranged on the side wall of the heat-preserving barrel body, and enters the heat-preserving barrel body to stretch into the conical barrel; a flared air outlet is formed at one end of the dry and hot air conveying pipe inside the conical barrel; a gate valve is arranged at the bottom of the conical barrel; and a screen plate is arranged below the gate valve. The small masterbatch drying device solves the problems of non-uniform drying and high energy consumption cost, eliminates a caking phenomenon in a masterbatch drying process, and reduces influence of the non-uniform moisture content of masterbatch on color yarn production.

Description

technical field [0001] The invention belongs to the technical field of drying protection devices, in particular to a small-sized color masterbatch drying device. Background technique [0002] In the production process of colored silk, the drying process of the masterbatch is the key process. The main task is to dry the masterbatch. After reaching the moisture content index, inject it into the screw quantitatively through the syringe, and heat and extrude the melt spinning together with the chips. Colored polyester filament. If the moisture content of the color masterbatch is not uniform and stable after drying and fails to meet the production index requirements, it will have a great impact on the production of colored silk. Product quality and manufacturing rate cause great loss. In order to stabilize the moisture content of the masterbatch, the general color silk factory uses a small drying tower to dry the masterbatch. However, the small drying tower is only used to dry ...

AI Technical Summary

Problems solved by technology

However, this method has many disadvantages when drying masterbatches below tens of kilograms: 1. When a small drying tower dries small batches of masterbatches of tens of kilograms, the amount of masterbatches in the tower is small, Low material level can easily cause compressed air to short circuit in the middle of the masterbatch, making the masterbatch dry and heated unevenly, and the moisture content is unstable

2. When the small drying tower dries small batches of color masterbatches of tens of kilograms, the cost of energy consumption is very high
