Cooling machine introduction
The counterflow cooler is mainly composed of a rotating closed air feeder, an air outlet top cover, a rhombic bulk material, a cooling box body, an upper and lower level positioner, a deceleration brake motor, an eccentric transmission spool type discharge mechanism, and a fixed frame adjustment. The device, the collecting hopper, the frame and the suction system are composed of the same.
Use, scope of application and performance feature
(1) Use and scope of application
Cooling of the pellets is an indispensable process in the granulation section. The counter-flow cooler can cool the pellets from the granulator at a temperature of 70 ° C to 90 ° C to a temperature slightly above room temperature of 3 ° C to 5 ° C, and can be reduced to safe moisture (≤ 12.5%), which is convenient for pellets. Transportation, storage The octagonal counterflow coolers are available in different models and can be adapted to feed mills of all sizes.
The counterflow cooler is a new type of cooler popular in the world. It uses the principle of countercurrent cooling to cool the high temperature and high humidity pellets. That is, the ambient cold air passes vertically through the layer and is first contacted with the cold material. The hot wind is in contact with the hot material, and the direction of the wind flow is opposite to the direction of the flow, so that the pellets are gradually cooled in the forward direction, and the particles caused by the quenching of the particles due to the direct contact of the cold air with the high-temperature pellets can be avoided. Surface cracking, because cold air enters the cooler from all sides of the bottom, the air inlet area is large, the cold air utilization rate is high, therefore, the cooling effect is remarkable, and the machine has low energy consumption and easy operation, so the counterflow cooler is superior to the former Replacement of horizontal and horizontal coolers.
