Description

technical field [0001] The invention relates to an explosion tank for explosive consolidation and explosion synthesis, in particular to an explosion tank that can quickly discharge high-pressure gas generated by the explosion, so as to minimize the impact of air shock waves on the tank wall, prolong the service life of the tank body, reduce The explosion tank with vertical opening and separable tank body and bottom can save time and effort and improve the efficiency of explosion, which can recover the loss of powder, reduce the cost of explosion. Background technique [0002] Explosive consolidation and explosive synthesis, also known as explosive compaction, is a general term for the technology of using explosive energy to consolidate powder materials into a block or synthesize another material through flying sheets. For example, the synthesis technology of explosive nano-polycrystalline diamond is Using explosion energy to convert graphite into nano-polycrystalline diamond...

AI Technical Summary

Problems solved by technology

[0004] 1. As a result of the seal, the air shock wave generated by the explosion has a greater impact on the tank wall, shortening the service life of the tank. For this reason, some tanks are specially equipped with vacuum equipment to make the explosion proceed in a vacuum state. In order to reduce the pressure of the air shock wave, adding vacuum equipment not only increases the explosion cost, but also increases the interval between each explosion and reduces the explosion efficiency because the vacuum is time-consuming;

[0005] 2. Although the high-pressure gas produced by the explosion of the explosive in the tank is sufficient to expand, there is still enough overpressure. In order to continue to work, ventilation must be performed after the explosion. When there is no ventilation equipment, the door hole must be opened immediately for natural ventilation. , but natural exhaust under overpressure will form a very rapid flow, which will take away the powder product and cause recovery loss

In this patent specification, a horizontal explosion tank is disclosed, that is, the openings on the tank body are arranged at both ends in the horizontal direction. Although the explosion can be carried out under normal pressure and the air is naturally exhausted, the cost of the explosion is reduced, but due to the The sheet is vertically downward, and it also produces an upward reaction force on the explosive gas. The horizontal opening set cannot discharge the high-pressure gas generated by the explosion at the fastest speed under normal pressure, so that it cannot weaken the air shock wave to the greatest extent. The impact on the tank wall, prolonging the service life of the tank body and improving work efficiency cannot fundamentally solve the problem of powder recovery loss, and the powder loss can still reach 3~5%.

In addition, since the tank body cannot be moved, the operator needs to enter the tank body from the entrance (600mm) to operate before each explosion, which is time-consuming and labor-intensive, which affects work efficiency
