Embodiment

[0015] Such as figure 1 As shown, the drying and regeneration process of a drum dehumidification dryer is used, which includes a drying circulating air system and a regeneration circulating system.

[0016] The flow of the dry circulating air system is: drying cylinder DH-1→filter LF-1→cooler CO-1→one cylinder dehumidification source DC-1→drying regeneration fan BL-1→drying heating pipe EH -1→drying cylinder DH-1;

[0017] The flow of the regeneration cycle system is: filter AF-1→dry regeneration fan BL-1→regeneration heating tube EH-2→one-drum dehumidification source DC-1→empty;

[0018] The material to be processed is sucked by the conveying suction pipes DM-1 and DM-2, and conveyed to the automatic simple mixing device AS-1 through the PVC hose PM-1 and PM-2 / 3. After mixing, it enters the primary conveying hopper AL-1. Then it is discharged after being dried and regenerated by the above-mentioned drying circulating air system and regenerative circulating system. The dryin...

Abstract

The invention relates to a drying and regenerating process adopting a one-cylinder type dehumidification dryer. The process comprises a circulating air drying system and a regenerative circulating system, wherein the flows of the circulating air drying system comprise passing through a drying cylinder, a filter, a cooler, a one-cylinder type dehumidification source, a drying regenerative blower, a drying heating tube and the drying cylinder; and the flows of the regenerative circulating system comprise passing through the filter, the drying regenerative blower, a regenerative heating tube and the one-cylinder type dehumidification source, and emptying. The process comprises the following steps: putting articles to be treated into the drying cylinder, dehumidifying out moisture of the articles to be treated by dehumidified hot air, adsorbing the dehumidified moisture passing through the one-cylinder type dehumidification source at circulation along with dry air by a molecular sieve in a dehumidifying cylinder, and conveying the dehumidified moisture of the articles to be treated to a host for shaping and using. Compared with the prior art, the process has the characteristics of simple structure, low cost, little occupied space, and the like.

Description

technical field [0001] The invention relates to a dryer, in particular to a drying regeneration process using a cylinder type dehumidification dryer. Background technique [0002] At present, the dryers in the plastic auxiliary machinery industry are mainly divided into two types: hot air dryers and dehumidification dryers. Among them, the dehumidification dryer traditionally adopts the rotary honeycomb dehumidification source. There are drying, regeneration, and cooling process controls respectively, and drying and regeneration fans are used on the equipment. In addition, it is equipped with conveying device and other functions. [0003] The cost of this design is relatively high, firstly: the price of the rotary honeycomb dehumidification source remains high, and the manufacturing process is complicated; secondly: there are many fans required, including three fans for drying, regeneration, and transportation, which consumes a lot of energy and takes up The space is larg...
