Title:
CLASSIFIER FOR FINE PARTICLE OF CRUSHED SAND
Document Type and Number:
Japanese Patent JP3523621
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a classifier for fine particles of crushed sand which dries crushed sand with heat of exhaust gas from engines installed in peripheral sand preparation equipment by taking the exhaust gas into an air flowing-in chamber, thereby preventing the crushed sand from adhering to the inside of the classifier, and which clarifies the exhaust gas by a dust collector used for collecting fine particles to contribute to environmental preservation.
SOLUTION: A plurality of receiving plates 30 are arranged stepwise in a main body 1 so that a classifying surface 3 is formed to move crushed sand from an upper stage to a lower stage. A netlike body 32 is extended in the movement direction from the tip part of each receiving plate. Air blowing out from an air flowing-in passage 31 through an air intake port 70 and an air flowing-in chamber 5 is blown into the classification chamber 4 from below of the netlike body. Exhaust gas ports 101 for power engines, driving engines 100, etc., installed in the peripheral sand preparation equipment are connected to the air intake port.
