Sectional type advection smoke discharging drying device and drying method

Abstract

The invention discloses a sectional type advection smoke discharging drying device. The drying device comprises a hydraulic kiln car pusher (1) and a drying chamber (10); the drying chamber comprises 22 kiln car position spaces and is divided into four sections; a drying chamber hot air blower (3) is arranged beside the side edge of the drying chamber (10); a hot air pipeline of the drying chamber hot air blower (3) leads to the interior of the drying chamber from the top of the drying chamber (10); a drying chamber dehumidifying fan (4) is arranged at the top of a kiln head of the drying chamber; an air draft pipe connected to the drying chamber dehumidifying fan (4) leads to the interior of the kiln head of the tunnel drying chamber from the top of the drying chamber; a drying chamber main moisture eliminating fan (5) is arranged at the top of the drying chamber; and an air draft pipeline connected to the drying chamber main moisture eliminating fan (5) is connected to an exhaust pipeline of the drying chamber dehumidifying fan (4). The drying device and the drying method have the advantage that the problems that the production efficiency is low and the drying effect is not obvious due to the facts that a traditional tunnel kiln adopts a multi-channel structure, the drying time is 22-28 hours per batch of green bricks, and the moisture content of the dried green bricks is more than 10% can be solved.

Description

technical field [0001] The invention relates to a drying system and a drying method, in particular to a segmented advection smoke exhaust drying device and a drying method, belonging to the field of building materials. Background technique [0002] With the extensive application of building materials in all aspects of production, the mass production of brick kilns has been paid more and more attention in various places. In the production process of bricks, the drying room of bricks is an indispensable link. The effect determines whether the various technical indicators of the sintering of the entire brick are up to standard, and the length of drying time determines the level of production efficiency. The traditional tunnel kiln adopts a multi-channel structure, and the brick is dried by using the wind from the Kazakh outlet of the side wall, but the drying room It is difficult to control the internal temperature. The temperature of each section has a great influence on each ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: provide a kind of planar circulation tile tunnel kiln, solve the problem through a kind of planar circulation tile tunnel kiln. The traditional tunnel kiln adopts multi-channel structure, the drying time is 22-28 hours for each batch of bricks, Moreover, the moisture content of the bricks after drying is all above 10%, which leads to the problems of low production efficiency and inconspicuous drying effect
