Explosion suppression method and device of industrial powder explosive production line

Abstract

The invention discloses an explosion suppression method and a device of an industrial powder explosive production line. The device comprises an explosive delivery screw conveyor and an explosive cooling screw conveyor; a upwards vertical first feed port is formed in the lower end of the explosive delivery screw conveyor; a upwards vertical first explosion venting port and a downwards vertical first discharge port are respectively formed in the upper ends of the explosive delivery screw conveyor; a upwards vertical second feed port and a downwards vertical second explosion venting port are respectively formed in the lower end of the explosive cooling screw conveyor; and a downwards vertical second discharge port is formed in the upper end of the explosive cooling screw conveyor. The explosive delivery screw conveyor and the explosive cooling screw conveyor are flexibly connected through an explosion suppression rotary valve and a dustproof cloth bag to form a complete explosion suppression conveying facility; when accidents occur, part of explosion pressure is released from the explosion venting port of the explosive delivery screw conveyor, and is weakened by the explosion suppression rotary valve and the dustproof cloth bag; and the explosion pressure of explosion waves crossing over the explosion suppression rotary valve is released from the explosion venting port of the explosive cooling screw conveyor to finally achieve the purposes of explosion extinguishing and explosion suppression.

Description

technical field [0001] The invention relates to an explosion-proof method and device for an industrial powder explosive production line, belonging to the technical field of industrial explosive production. Background technique [0002] On December 29, 2014, the Ministry of Industry and Information Technology issued the "Implementation Plan for the Special Project of Civil Explosive Safety Production with Less (No) Humanization" (Gongxintingzhuang [2014] No. 271), encouraging civil explosive equipment manufacturers to adopt automation and information technology , speed up the transformation of the traditional production mode and management mode of the enterprise, improve the reliability of the process and equipment, and promote the upgrading of the existing production process, equipment and products; strengthen the online detection and quality control in the production process, and improve the accuracy of product technical indicators Safety and reliability; reduce the number ...

AI Technical Summary

Problems solved by technology

However, the existing explosion-proof measures for the production line of industrial powdered explosives are not perfect enough. When an accident occurs in the pharmaceutical process, the detonation wave cannot be released quickly and effectively, and it cannot meet the requirements for the production of powdered explosives in a factory from pharmaceuticals to finished product packaging. The process realizes automation and continuous production, and there are potential safety hazards
