Air chuter

Abstract

Abstract PURPOSE: To lighten the impact in transferring and prevent injury of article to be transferred by gradually increasing the transfer pressure in a chuter in conveying ores and arranging an air exhausting device before a receiver. CONSTITUTION: When article to be transferred is thrown into the throwing port 2 of a chuter 1 under the planned transfer pressure set by a pressure adjuster 8, a shutter valve 3 is opened, and the article to be transferred drops into a pressure chuting chamber 4. After the shutter valve 3 closes again, a main valve 9 is opened gradually, and the transfer pressure in the pressure chuter chamber 4 is increases up to a prescribed value, and then the article transferred is sent through a transfer pipe 5 from the pressure chuter chamber 4. The article transferred from a sender 1 is decelerated to an optimum speed at the point passing through the last exhaust device 19a, and afterwards, the pressurized air in the pipe to a slide valve 18 acts as cushion, and the article transferred is softly landed to the slide valve 18. Then, the slide valve 18 is opened, and the article is discharged into a receiver 6. COPYRIGHT: (C)1981,JPO&Japio
