Pigment, Dyestuff, Catalyst Special Belt Drier

1,process description:
Wet materials after the extruding machine squeeze into strips on the belt drier on the top of the charging period, as the mesh belt to move forward, strip material was evenly in the dryer mesh, mesh belt in gear drive to move forward at a constant speed, the net belt material from the loading port to the other end, and then fall into the second layer mesh belt, the material after the second layer mesh belt into the underlying mesh belt, and then discharge from the bottom of the discharge end, in the process of this material wear streaming dry by internal hot air drying machine, so that the material loss of moisture.
Drying section consists of several independent units, some of the exhaust outlet by discharge, each unit displacement air valve control. In cycle unit, hot air circulation flow under the action of circulation fan, quantity of heat is provided by hot blast stove, enter each unit through the hot air port, to keep the drying temperature in certain range. Drying process is a hot air flow through the material layer, complete the process of heat transfer.


2,Design features:
drying equipment, reasonable structure, convenient control, energy conservation and emissions reduction, no dust pollution, to achieve national environmental standards.
Equipment designed to three layers of mesh belt, according to the different characteristics of the material in different phases of dry flexible parameter set dry, in the upper, the moisture content of material is bigger, can execute laying the material thickness of smaller and faster mesh belt speed; When the underlying material moisture content decreases, and may apply the larger spread thickness material and mesh belt speed slower, prolong the retention period of material, make the material thoroughly dry. The hot air inside the equipment through the three layers of net belt material, heat transfer, achieve the goal of energy conservation and efficient; Humidity is higher, the top of the materials to produce small amount of dust and dust discharged from the outlet is relatively small, achieve the goal of energy conservation and emissions reduction. Are hot air import equipment of each unit, each unit has hot air import layer and layer, the first three units, each layer has a hot air imports), each hot air import air regulating valve, inlet is equipped with the wind vane, effectively guarantee the uniformity of hot air and the regulation of sex.
