Description

Molecular sieve barrel structure for drying

Technical Field

Background

In the process of processing and forming plastic products, hot air is often required to be used for drying plastic products or semi-finished products, and the hot air is formed by heating air by using a heater, so that the plastic products or the semi-finished products inevitably contain certain water vapor, and if the water vapor in the hot air is not removed firstly, the drying effect of the plastic products or the semi-finished products is greatly affected. At present, the industry is provided with dry hot air through a molecular sieve barrel, and the working principle is as follows: after the air comes in from the air inlet of the screen barrel, the air is heated into hot air through the heater, then flows to the air outlet of the screen barrel along the air passage, and the heat absorbing medium in the screen barrel absorbs the water vapor contained in the heat absorbing medium in the flowing process of the hot air, so that the dry hot air flows out from the air outlet.

The existing molecular sieve barrel is unreasonable in structural design, inconvenient to assemble, time-consuming and labor-consuming in assembly, and meanwhile, water vapor in hot air cannot be completely absorbed, so that the drying effect of plastic products is not ideal. For this reason, the inventors have improved the structure of the existing molecular sieve barrel for drying.
