A pvc additive drying device

Abstract

The invention relates to the field of drying, and specifically discloses a PVC auxiliary drying device, which includes a drying box, a filter mesh conveyor belt is installed in the drying box, the upper and lower belt surfaces of the filter mesh conveyor belt are arranged horizontally, and the feed end of the filter mesh conveyor belt is Equipped with a material distribution mechanism, an air supply mechanism is installed below the upper surface of the filter conveyor belt. The air supply mechanism is used to provide low-temperature hot air to the upper surface of the filter conveyor belt. The mesh conveyor belt moves back and forth along its width direction and shakes up and down. The drying device proposed by the present invention has reasonable layout, stable structure and stable operation, and can realize continuous and automatic low-temperature drying treatment of granular PVC auxiliary materials, and can realize adjustment The material is continuously combed and separated to achieve adjustment. The material is continuously raised and shaken, so that the material can be fully contacted with the low-temperature hot air, and the efficiency of the contact between the material and the low-temperature hot air is effectively improved, and the drying efficiency is greatly improved, which meets the current low-temperature drying. requirements.

Description

technical field [0001] The invention relates to the drying field, in particular to a PVC auxiliary drying device. Background technique [0002] Pure PVC resin is easy to decompose, has poor fluidity, low impact strength, and poor weather resistance during processing. Therefore, it is necessary to add various auxiliary materials to improve its performance during processing, such as: lubricants, heat stabilizers, impact modifiers, Processing aids, etc. [0003] In the process of development and application of processing aids, they are roughly divided into the following categories according to product components: methyl methacrylate (MMA) / acrylate copolymer, MMA / styrene copolymer, acrylonitrile / styrene, etc., used The one with the largest amount and the best effect is MMA / acrylate copolymer. [0004] One of the PVC additives is in the form of granules. After production, the sundries are washed away after production, and then drying is required. In order to maintain the stabil...

Problems solved by technology

[0004] One of the PVC additives is in the form of granules. After production, the sundries are washed away after production, and then drying is required. In order to maintain the stability of PVC additives, low-temperature drying is required. The current drying equipment has a single structure. The function is single, and the low-temperature drying efficiency is poor, which cannot meet the current use requirements
