Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosives, in particular to a high-temperature static sensitized emulsion explosive sensitization decompression device. Background Art

[0002] When the emulsion explosive is started for daily production, the operator adjusts the three-way valve on site to release all the explosive heads. When adjusting the three-way valve from external discharge to the charging machine, it will pass through a short outlet opening and closing blind area. During this short period of time, the pressure at the sensitizer outlet will instantly increase several times, which can easily cause the sensitizer seal to leak, causing equipment wear and posing serious safety hazards to the production of emulsion explosives. The existing device cannot ensure sealing at the three-way valve joint, which can easily shorten the equipment life, and a single pressure relief device may cause safety hazards.

[0003] The application number is 201920029324.6, which discloses a high-temperature static sensitized emulsion explosive sensitization decompression device, including a decompression tower group and a pressure control system. The decompression tower group includes a first decompression tower, a second decompression tower and a third decompression tower. The left end of the decompression tower group is connected to the sensitizer body, and the right side of the decompression tower group is connected to the decompression main valve. The decompression main valve is connected to the pressure control system. The first decompression tower, the second decompression tower, the third decompression tower and the decompression main valve are connected in series through a decompression tower series pipeline, and the first decompression tower, the second decompression tower and the third decompression tower are connected in parallel through a decompression tower parallel pipeline. This device can quickly open three groups of decompression towers to reduce pressure when the outlet pressure of the sensitizer increases through a parallel decompression tower group, with fast decompression and high safety. It can adapt to the decompression control in the low-pressure process through the series decompression tower group, and monitor the rapid increase of the sensitizer link. It has high practicality and good pressure control effect.

[0004] However, there are some shortcomings: although the pressure reducing device used in this device can meet the pressure control effect, the parallel pressure control method adopted is likely to increase the cost, and no fixing device is added to the three-way valve joint, which is prone to safety hazards.
