A dust collection and drainage system for flour conveying

Abstract

A dust collection and drainage system for a flour conveying silo includes a spray mechanism mounted on the silo. A filter screen is fixedly installed inside the silo, dividing it into a first compartment and a second compartment. Each compartment is equipped with a scraping mechanism for removing water. Both compartments also have open flame detectors for detecting sparks. A controller is fixedly mounted outside the silo. Drainage pipes, connected to the bottom of each compartment and fitted with valves, are installed at the bottom of the first and second compartments. When the open flame detector detects a spark inside the silo, it converts the detection signal into an electrical signal and transmits it to the controller. The controller then activates the spray mechanism to extinguish the fire and simultaneously reduce flour dust, preventing dust explosions and promptly eliminating safety hazards.
