Dehumidification dryer

Abstract

The invention discloses a dehumidification dryer. A tube of a dehumidification device is of a spit structure provided with a tube body, an upper cover and a lower cover; the tube body and the upper cover are detachably connected through a first hoop; the tube body and the lower cover are detachably connected through a second hoop; and sealing is performed by an upper sealing ring arranged betweenthe tube body and the upper cover and a lower sealing ring arranged between the tube body and the lower cover, so that a molecular sieve located in the tube not only can be conveniently replaced but also can keep isolated from outside air.

Description

technical field [0001] The invention relates to a dehumidification dryer. Background technique [0002] Plastic particles need to be dehumidified and dried before injection molding to prevent air bubbles in the plastic products. The dehumidification devices of the existing dehumidification and drying equipment are roughly divided into two types. One is a silicone honeycomb runner. The equipment structure using this device complex, high energy consumption, and difficult miniaturization; the other is molecular sieve, the equipment using this device has simple structure, low energy consumption, and is easy to miniaturize, but because molecular sieve has strong hygroscopic ability, in order to prevent it from being exposed to the air, it usually requires The molecular sieve is injected into the container and then sealed by welding. When the molecular sieve fails and needs to be replaced, the entire container needs to be replaced, which is time-consuming, laborious and costly. ...
