METHOD FOR DISCHARGING GRANULAR MATERIAL WHICH HAS BECOME FIXED INSIDE HOLLOW STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/193803
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a method for discharging a granular material which has become fixed inside a hollow structure (silo or the like), by which granular material which has become fixed inside the silo can be safely discharged from a discharge port in the bottom of the silo. [Solution] The method for discharging a granular material includes the following. A rack rail 7 is suspended inside a silo 1 from an opening 5 formed in a ceiling portion 4 of the silo 1; a lifting and lowering body 8 is lowered from the opening 5 along the rack rail 7 into the silo 1; a work scaffold 10 is constructed on the lifting and lowering body 8 using the parts 9 carried into the silo 1 from the opening 5; with a discharge port 3 of the bottom of the silo 11 closed, a worker 13 connected to the work scaffold 10 with a safety belt 12 knocks down the granulated material 2 thereby causing the knocked-down granulated material 2 to fall into a rat hole (or boring hole) 14; and in a state in which the rat hole 14 is clogged by the granular material 2, the worker 13 connected to the work scaffold 10 with the safety belt 12 extends the rack rail 7, opens the discharge port to discharge the granulated material 2 stored in a passage 14, and lowers the work scaffold 10 to the extended rack rail 7.
