AI Technical Summary
The limited area of indirect contact between the paint and cold water leads to localized overheating. The heat in the high-temperature paint cannot be dissipated quickly, which can easily cause clumping and adhesion.
The material feed plate has a serpentine water channel and an air cooling chamber on its inner side. It uses coolant and cold air to cool the high-temperature coating. The serpentine water channel keeps the upper part of the material feed plate at a low temperature, and the cold air conveying component sends cold air to the upper part of the material feed plate for rapid cooling.
This technology enables rapid cooling of high-temperature coatings, preventing clumping and adhesion, and reducing energy consumption in subsequent pulverization processes.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder coating processing technology, specifically to a cooling tower for powder coating processing. Background Technology
[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. In the powder coating production process, the molten mixture is extruded through an extruder outlet, and the extruded high-temperature coating needs to be cooled down promptly.
[0003] Currently, the mainstream cooling method is water cooling. This method involves indirectly contacting the coating with cold water, taking advantage of water's high specific heat capacity to absorb heat from the coating. However, this cooling method limits the area of indirect contact between the coating and cold water, which can easily lead to localized overheating. Furthermore, the indirect contact with cold water makes it difficult to quickly dissipate the heat from the high-temperature coating, which can easily cause clumping and adhesion, increasing energy consumption in subsequent pulverization processes.
[0004] To address the aforementioned technical problems, this application proposes a cooling tower for powder coating processing. Utility Model Content

A cold air conveying assembly connected to the air cooling chamber is installed on the side wall of the shell to send the cooled air inside the air cooling chamber into the shell to quickly cool the high-temperature material moving on the upper side of the feeding plate.
