Safe and explosion-proof pyrotechnic composition milling device

Abstract

The invention discloses a safe and explosion-proof pyrotechnic composition milling device. A rack of the device is sequentially provided with an automatic feeding mechanism, a primary grinding system, a secondary grinding system, a vibrating screen and a material collection box from top to bottom, wherein transition connecting seats which are communicated with each other are arranged between the primary grinding system and the secondary grinding system; each of the primary grinding system and the secondary grinding system consists of a driving copper roller and a driven copper roller which are meshed with each other, as well as a driving device. The materials are fed into the primary grinding system for grinding and breaking and drop in the secondary grinding system for grinding and breaking again, and the materials which meet the requirements are collected in the material box through the vibrating screen. The manual operation is replaced by mechanical operation, non-contact operation is realized through man-machine integration and the mechanical hand, and the device has anti-explosion, flameproof and firefighting functions.

Description

technical field [0001] The invention relates to a grinding device, in particular to a safe and explosion-proof pyrotechnic chemical grinding device. technical background [0002] Fireworks and firecrackers are a traditional industry in my country. At present, most of them are labor-intensive industries. At the same time, fireworks and firecrackers are inflammable and explosive dangerous industries, which can lead to frequent production accidents. As an inspection and supervision agency for fireworks and firecrackers, the sample preparation of fireworks and firecrackers is relatively dangerous. Among them, there have always been high risks in grinding samples, screening and other links. There have been some incidents of injury and damage, but there is no good solution at present. [0003] At present, most pyrotechnic agents still use manual direct contact operation, and there is no safety system for sample grinding and sieving in the sample preparation process.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the pyrotechnic agents are operated by manual direct contact, and there is no safety system for sample grinding, sieving and other processes in the sample preparation process.

The Jiangxi Inspection and Quarantine Bureau has developed a large-scale firework dissection device (patent publication number CN200944027), and the Hunan Inspection and Quarantine Bureau has developed a large-scale fireworks dissection device and drug pressing device, which better solve the problems of anatomy and drug pressing in the inspection process of fireworks and firecrackers. Safety issues, but there has been no sample preparation safety device and system that can eliminate safety hazards in pyrotechnic agent grinding, sieving and other links

At present, most production enterprises and testing institutions still use manual direct contact operations in the grinding and sieving of pyrotechnic agents, which has huge potential safety hazards
