Drying device of ACR spray drying tower

Abstract

The invention belongs to the technical field of spray drying, and discloses an ACR spray drying tower drying device which comprises a supporting shell and a monitoring assembly, an air inlet groove is formed in the top end of the supporting shell, a heating device is fixedly installed at the right end of the air inlet groove, and a discharging device is fixedly installed at the left end of the supporting shell. And a feeding device is fixedly mounted at the top end of the supporting shell. Hot air generated by a heating device is sucked into a rotating box through an air inlet assembly, an air spraying pipe is driven to rotate through meshing of a gear and a gear ring, the hot air sprayed out of the air spraying pipe can form complete and uninterrupted airflow, and the rotating assembly is driven by a driving assembly to rotate in an inner cavity of a drying cylinder; and hot air making contact with the raw materials is driven to rotate, then the hot air and the raw materials rotate and move downwards in the inner cavity of the drying cylinder, it is guaranteed that the raw materials with the high humidity can be fully dried when the raw materials make contact with the hot air in the drying cylinder, and the drying effect of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of spray drying, in particular to an ACR spray drying tower drying device. Background technique [0002] In the process of PCV processing, ACR resin plays a role in accelerating plasticization and changing the flow properties of thermoplastic form. In the production process, a spray drying tower is required to dry the ACR resin raw material to make the fluid raw material into powder. [0003] When the drying devices in the prior art are in use, most of them use an atomizer to atomize and spray the raw materials, and contact with hot air, and then use the hot air to dry the raw materials. Down into the drying cylinder, when the hot air flows, the hot air entering from the top of the drying cylinder will flow directly to the bottom end of the drying cylinder, and in the process of flowing, the raw materials will be transported downward for discharge, but when When the humidity of the raw material is high, the...

AI Technical Summary

Problems solved by technology

[0003] When the drying device in the prior art is in use, the atomizer is mostly used to atomize and spray the raw material, and contact with the hot air, and then use the hot air to dry the raw material, but in actual work, the hot air mostly comes from above When the hot air flows downward into the drying cylinder, the hot air entering from the upper part of the drying cylinder will flow directly to the bottom of the drying cylinder, and will drive the raw materials to be transported downward for discharge during the flow process. When the humidity of the raw material is high, the raw material may spend less time in the drying cylinder, and the raw material cannot be completely dried, which reduces the drying effect of the device
