A device for convenient classification and collection of explosive test fragments

Abstract

The invention belongs to the field of research of explosion tests in an explosion tank and particularly relates to a device facilitating sorted collection of explosion test fragments.The device comprises the explosion tank, the top of the explosion tank is provided with a top door which can be opened or closed, and a plurality of layers of stacked recycling nets for sorted collection of the explosion test fragments are arranged in the explosion tank.For every two adjacent layers of recycling nets, the mesh size of the recycling net located on the upper layer is larger than that of the recycling net located on the lower layer, each layer of recycling net is in a net bag shape with the upper portion provided with an opening, the edge of the upper portion opening of each layer of recycling net is provided with a connecting structure, and the recycling net is detachably connected with the side wall of the explosion tank through the connecting structure.The device has the advantages of being high in test efficiency, saving manpower, being good in safety and convenient to clean.

Description

technical field [0001] The invention belongs to the field of explosion test research in an explosion tank, and in particular relates to a device for conveniently sorting and collecting explosion test fragments. Background technique [0002] At present, the explosive tank is often used in the explosion test room to carry out the explosion test. The concrete standard sample charge is placed in the explosive tank to detonate, and then the fragments of the concrete after explosion of different sizes are collected to obtain its fragmentation, and then the performance of the explosive is judged. In the prior art, it is necessary to manually install and place the test blocks before the explosion, and it is also necessary to manually classify and count the fragments after the explosion according to different weights, so as to obtain the distribution of different block sizes. There are many deficiencies in the existing technology: for example, manually installing and placing the test...

Problems solved by technology

There are many deficiencies in the existing technology: for example, manually installing and placing the test blocks before the explosion not only consumes manpower, but also has safety risks; for example, purely manual classification and statistics of the fragments after the explosion according to different weights consumes a lot of manpower and time, the test efficiency is low, and it is prone to difficulties and omissions in the collection of fragments, resulting in experimental errors
