Multilayer clean tunnel furnace

Abstract

The invention discloses a multilayer clean tunnel furnace. The multilayer clean tunnel furnace comprises the following parts arranged in a material conveying direction in sequence: a loading lifting platform for lifting and conveying materials within a preset height, a multilayer preheating section including multiple first conveying layers and used for preheating the materials on each of the first conveying layers, a multilayer heating section including multiple second conveying layers and used for heating materials on each of the second conveying layers, a multilayer precooling section including multiple third conveying layers and used for precooling materials on each of the third conveying layers, an unloading lifting platform for lifting and conveying materials within a preset height, a wind leaching cooling section for cooling the materials, and a discharge platform for sending out the materials. The multilayer clean tunnel furnace has such multiple beneficial effects as uniform material heating, good cleanness, high production efficiency, short production line and energy and space saving.

Description

technical field [0001] The invention relates to a tunnel furnace, in particular to a multi-layer clean tunnel furnace. Background technique [0002] At present, traditional tunnel ovens all use infrared rays and heat pipe heating methods, and most of them are tiled structures. This method is easy to cause uneven heating in the area, that is, the heating products are unevenly heated, and the cleanliness of the internal environment is difficult to control. In order to achieve the baking time and production capacity, it is necessary to lay out a long production line, occupy a large area of ​​the factory building, and at the same time consume energy. It is also very large and cannot meet the energy-saving and efficient production requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-layer clean tunnel furnace with uniform heating of materials, good cleanliness, high production efficiency, short produ...
