Example Embodiment

[0045] Example 1:

[0046] Figure 1 is a schematic diagram of the flow of hot air as the drying medium and the material to be dried in the drying section 1. The figure shows four drying sections, that is, there are four drying processes. The dryer 5 is divided into a number of drying zones in the material movement direction a, and each drying zone is divided into four drying sections 1 along the main channel 9 and separated from each other by the air duct and wind barrier 16, each drying section 1 The main passages are separated by the airflow barrier 15; the air outlet end of each drying section 1 is connected with the air inlet end of the next drying section. In its drying zone, the hot air that provides heat for the drying process adopts a four-process cross-flow circulation, that is: the hot air flows through four drying zones in each drying zone in a flow direction perpendicular to the conveying direction of the material to be dried. Each time it passes through a drying secti...

[0047] Example 2:

[0048] Figures 2 to 5 are schematic diagrams of the structure of the dual-process drying section, which uses a two-stage drying section, which is a dual-process. A drying zone of the dryer 5 shown is composed of two drying sections 1 that are closed and tightly connected; each drying section 1 is provided with a multi-layer conveying roller table 6, which is perpendicular to the conveying direction of the gypsum board. There is an air blowing nozzle 4 between every two adjacent conveying rollers 6, the supporting bearings at both ends of the conveying rollers 6 are fixed on the beams of the corresponding dryers 5, and the conveying rollers 6 are arranged in the main aisle 9. Both sides of the main channel 9 are respectively provided with a non-drive side auxiliary channel 10 and a transmission side auxiliary channel 12, in which the upper part of the non-drive side auxiliary channel 10 is provided with a top channel 11, and a circulating fan 3 and a heating dev...

Abstract

The invention relates to multi-paths horizontal circulation drying device for plasterboards and a drying method thereof, and the drying device is formed by a roller conveyer with the closed inner portion provided with one layer, multi-layers in most cases, and an air circulating device, wherein the roller conveyer is disposed in a main passage, two sides of which are provided with auxiliary passages, the upper portion of the auxiliary passage on one side is provided with an overhead passage, and a circulating fan and a heating device are arranged inside the overhead passage. The drying device is divided into a plurality of areas in the direction of material delivery, each area can be divided into 2-4 segments, each segment is provided with a plurality of air supply blowing pipes, and the main passages of each segment are provide with air flow resistant separators. Hot air as drying medium flows reversely at the first and second segments or the third and the fourth segments via the air supply blowing pipes, and reciprocates and circulates within the plate drying area by horizontal double-paths or multi-paths, thereby forming the intrinsic inherent condition which guarantees moisture on the two sides of the dried plate to be uniformly evaporated, simultaneously the multi-paths horizontal circulation drying device has the advantages of flow resistance consumption reduction, exhaust temperature reduction, increasing energy efficiency and construction cost reduction.

Description

technical field [0001] The invention relates to a drying equipment for boards and strips, especially plasterboards, in particular to a multi-flow horizontal circulation gypsum board drying equipment and a drying method thereof which use circulating hot air to provide heat energy for the drying process. Background technique [0002] At present, there are two main categories of drying equipment for continuous automatic industrial installations of wide-width boards, especially gypsum boards: [0003] One type can be called "longitudinal convection type", in which the flow direction of the circulating hot air is on the same straight line as the direction of movement of the board to be dried, parallel or reverse flow, less control sections, relatively simple structure, and low construction cost , the fan drive consumes less power, and the control effect on the drying quality of the board can generally meet the requirements, but it is not ideal under certain conditions; [0004] ...
