Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosives, in particular to a continuous production system for emulsion explosives. Background Art

[0002] The production process of emulsion explosives is to send liquid ammonium nitrate into the water phase storage tank until the ingredients are completed and reach the required concentration and temperature requirements. Then the composite oil phase material is weighed and placed in the oil phase storage tank for standby. The prepared water phase and oil phase solutions are filtered again, and then measured by the water and oil phase delivery pumps through flow meters and pumped into the continuous emulsifier in proportion through pressure-resistant hoses. The continuous emulsifier is sent to the latex storage silo through the discharge hopper and the latex matrix pump. The latex storage silo is loaded into the truck through the discharge pipe.

[0003] During the production process, due to the long interval between each loading, the water phase material remains in the discharge pipe for a long time. Affected by the ambient temperature, especially the low temperature in the north in winter, there is a crystallization problem, which causes the discharge pipe to be blocked and affects the normal operation of the next loading; the oil phase temperature is low. When the water phase and the oil phase are mixed in the emulsification stage, the low temperature of the oil phase will cause the water phase to cool down and crystallize, affecting the mixing effect and time, resulting in reduced work efficiency.

[0017] The outlet of the oil phase storage tank 11 is connected to the inlet pipeline of the oil phase transfer tank 13 through the first oil phase pump 12, the outlet of the oil phase transfer tank 13 is connected to the inlet pipeline of the pipe side of the heat exchanger 8 through the second oil phase pump 14, the outlet of the pipe side of the heat exchanger 8 is connected to the inlet pipeline of the oil phase transfer tank 13, the pipeline connection between the outlet of the pipe side of the heat exchanger 8 and the inlet of the oil phase transfer tank 13 is connected to the second inlet of the mixing tank 10 through the third delivery pipe 15, and the mixing tank 10 is connected to the inlet pipeline of the emulsion explosive storage tank 18 of the mixing vehicle 17 through the liquid outlet pump 16.

[0018] The heat exchanger 8 is used to exchange heat between the oil phase and the water phase, so that the water phase is cooled and the oil phase is heated, which reduces the crystallization problem caused by pre-cooling of the water phase in the mixing stage and improves the mixing efficiency; through the circulation of the water phase and the oil phase, the flow of the medium in the pipeline is guaranteed, and the residual medium in the pipeline is recovered in time, which reduces the crystallization phenomenon of the medium in the pipeline. At the same time, the water phase storage tank 3 and the oil phase storage tank 11 continuously add new medium according to the amount used, which also ensures the continuity of production.

[0019] It also includes a citric acid tank 19 and a citric acid pump 20. The outlet of the citric acid tank 19 is connected to the second delivery pipe 9 through the citric acid pump 20. Citric acid is added to the water phase as an additive, and the fusion of the citric acid and the water phase is achieved under the action of the second delivery pipe 9.

[0021] The operation process of this embodiment is as follows:

[0022] Initial circulation preheating stage: liquid ammonium nitrate is injected into the water phase storage tank 3 through the discharge pipe 2 by the discharge vehicle 1 and the first water phase pump 4, and then the water phase is injected into the water phase transfer tank 6 by the first water phase pump 4, and then pumped into the shell side of the heat exchanger 8 by the second water phase pump 7;

[0023] The oil phase in the oil phase storage tank 11 is sent to the oil phase transfer tank 13 by the action of the first oil phase pump 12, and then the oil phase is pumped to the tube side of the heat exchanger 8 by the action of the second oil phase pump 14;

At the same time, the oil phase after heat exchange is sent to the oil phase transfer tank 13 for circulation to increase the temperature of the oil phase in the oil phase transfer tank 13. When the temperatures of the oil phase and the water phase meet the mixing requirements, the water phase and the oil phase are sent to the mixing tank 10 according to a certain amount by using the corresponding valves.
