Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and more specifically to a mesh-belt type symmetrical air supply drying machine. Background Art

[0002] The mesh belt dryer is a batch and continuous production drying equipment that uses a steel mesh as a conveyor belt to carry materials for continuous drying. The mesh belt dryer mainly transports the finished product directly to the flat conveyor through a conveyor, and evenly distributes the finished product on the dryer through the scraper at the upper end of the flat conveyor to improve the air permeability and achieve the drying effect. The mesh belt dryer is a commonly used continuous drying equipment and can be widely used in building materials, electronics and other industries. It is particularly suitable for drying sheet, strip, and granular materials with good air permeability. For paste materials such as filter cakes, they can also be dried after being formed by a granulator or extruder.

[0003] At present, mesh belt dryers have different heat sources and different overall structures. Dryer with air energy as heat source: the heat generated by air energy enters the wind chamber, raising the temperature of the wind chamber, and then blows the hot air in the wind chamber into the drying chamber; when natural gas is used as the heat source, the heat generated by natural gas is directly blown into the drying chamber, and there is no wind chamber structure. If it is necessary to change the air energy heat source to a natural gas heat source in the future, the wind chamber of the air energy dryer needs to be dismantled, and the internal frame steel also needs to be cut. The change operation takes a long time, the recycling value of the dismantled part is low, and the labor cost and material cost are high. Therefore, it is necessary to provide a mesh belt symmetrical air supply dryer to overcome the above problems. Summary of the invention

[0004] The present invention provides a mesh-belt symmetrical air supply dryer to solve the problems that the existing mesh-belt dryers have different heat sources and different overall structures.
