Pigment special belt dryer has monolayer and multilayer type, single section and multi section branc

Pigment special belt drier is continuous drying equipment for mass production, and has the advantages of high drying rate, evaporation of high intensity, good product quality etc.. The pigments used special belt dryer drying of the material must have a certain shape, but still maintain a certain shape after drying.
　　Pigment special belt dryer according to its structure and the function of gas method is divided into two main forms: dryer with mesh belt dryer with no hole with. The first kind of dryer with a fabric (canvas, rubber belt, adhesive cloth) made of. Heat carrier (usually hot air) across the evenly on the belt is drying material layer. The flow direction and the belt to move in the opposite direction as same as countercurrent, and flow.
　　The second kind of dryer with metal or non metal mesh material, heat carrier to vertical direction bottom-up or top-down through the material layer. The dryer to dry in the top only with porous layer, and the heat carrier in through the material, this is called cross flow pigment special belt dryer, the models in industrial production is the most widely used.
　　No matter what kind of structure, the pigment special belt dryer is not suitable for dry without pre drying paste material.
　　Pigment special belt dryer has monolayer and multilayer type, single section and multi section branch, but the working principle is basically the same. Material in the hopper by feeder evenly in the mesh belt, moving forward with the conveyor belt. Drying unit of hot air inside the vertical through the material layer, so that the material dehydration. Mesh belt material layer thickness determined by factors of material properties, cloth and drying temperature adjustment, generally in the range of 20~100mm. Network with 12~16 mesh, made of stainless steel and non-metallic materials, according to need can also use stereo mesh belt. Moved by the transmission device in the drier dragging. Drying section is composed of a plurality of unit (the length is about 2m), each unit of hot air cycle, which part of the tail gas discharged by the special wet exhaust fan, exhaust volume of each unit are regulating valve control. In his coat a circulation unit, the hot air circulating fan out into the unit by the side of inferior vena duct, air flow through the heat exchanger, and the distributor, jet flow blows to the mesh belt, through the material into the cavity. Drying process is the heat flow through the material, complete the process of heat transfer. On the chamber by the air pipe is connected with a fan, and most of the gas cycle. A portion of the gas temperature is low, high moisture content as the wet exhaust pipe, exhaust valve, exhaust fan exhaust. Circular unit, circulating fan out of the wind to enter the chamber, up through the heat exchanger, through the material into the inferior vena cava, inferior vena cava by side air duct and the air return pipe and is connected with the fan entrance, most of the gas cycle, a portion of the exhaust. Upper and lower circulation unit according to the needs of the user can be equipped with flexible, unit number can be selected according to requirements.
