Description
Technical Field
The invention relates to the technical field of initiating explosive devices, in particular to a method and a structure for improving the transportation and ignition capacity of an ignition element of an electronic detonator.
Background
The continuous development and perfection of the electronic detonator technology, the technical superiority of the electronic detonator is more and more widely accepted in the global blasting world, particularly the maturity of the novel electronic detonator technology is continuously improved, the cost performance is gradually improved, and the market application of the novel electronic detonator technology is expanded from the early special engineering blasting field to common mines, quarries and other popular blasting construction operation fields.
In the transportation process of the ignition element of the electronic detonator, the explosive head is in an unprotected state and is very sensitive, the ignition element is likely to deform under the action of external force in the transportation process, if the explosive head of one ignition element is accidentally detonated, the flame of the deflagration can spread and lead the explosive heads of other ignition elements to be dragged, and thus accidents are caused.
Disclosure of Invention
The purpose of the invention is: the method and the structure can effectively protect the powder head of the ignition element, ensure the shape of the powder head to be intact, improve the safety in the transportation process, ensure the combustion direction of the powder head of the ignition element to have directivity and improve the ignition capability of the powder head.
The invention is realized by the following steps: the method for improving the transportation and ignition capacity of the ignition element of the electronic detonator comprises the steps of sleeving a protective sleeve on the explosive head part of the ignition element of the detonator, wherein the top of the protective sleeve is open, the protective sleeve completely surrounds the outer side of the explosive head of the ignition element of the electronic detonator, covering a layer of flame retardant plate on the top of the protective sleeve in the transportation process, and attaching the top of the protective sleeve to the flame retardant plate to ensure that the explosive head of the ignition element is in a relatively closed environment, so that the shape of the explosive head of the ignition element is protected to be complete in the transportation process, and flame diffusion when the explosive head of one ignition element is ignited can be prevented; and when normally igniteing, the protective sheath makes the burning of charge head have the directive property, has improved the ignition ability of charge head.
The protective sleeve structure for the ignition element of the electronic detonator comprises the ignition element of the electronic detonator and a sleeve body, wherein the sleeve body is of an annular structure, the sleeve body surrounds the outer side of the powder head of the ignition element, a gap of 0.5-2mm is reserved between the sleeve body and the powder head, the bottom of the sleeve body is attached to the top of the ignition element, and the top of the sleeve body is of an open structure.
The top of the sleeve body is 1-2mm higher than the top of the medicine head.
The protection sleeve adopts a hot air or contact heating mode to ensure that the protection sleeve is heated and contracted outside the explosive head and is used as an inherent component of the ignition element without being independently installed before transportation or taken down after transportation, and the protection sleeve can also ensure that the explosive head has directivity during combustion and improve the ignition capability of the explosive head. The invention has simple structure, low cost and good use effect.
