GAS GENERATING ADDITIVE SOLUTION PREPARATION DEVICE Russian patent published in 2025 - IPC C06B21/00 B01F33/80 

FIELD: performing operations.

SUBSTANCE: invention relates to mechanized production of water-resistant emulsion explosives. Device for preparation of gas-generating additive solution contains a mixer in the form of a container, inside which there is a mixer with a rotation drive, a heat exchange unit for maintaining the specified temperature of the mixed mixture inside the container. Said container has branch pipes communicating with solid dispersed component feed channel, solvent feed channel and mixed mix discharge channel, a hydraulic pump is located in the mix discharge channel. Container is placed on the platform of the weighing mechanism, made with a control unit, which implements the function of supplying a control signal to the actuating mechanism of the shutoff assembly in the solid dispersed component supply channel for its locking when the weight of the container is increased by a value corresponding to the weight of the supplied component, value of which corresponds to the set weight. Hydraulic pump outlet is communicated via filter and shut-off unit with container for return to it in mode of circulation through filter of mixture coming from channel of mixture discharge, and through shut-off unit is connected with ready mix discharge line. In the solvent supply channel in the section from the shut-off unit with the actuator installed in it to the connection with the container there is a mass Coriolis flow meter with a control unit connected to the weighing mechanism control unit, which is made with an additional function of supplying a control signal to the actuating mechanism of the shut-off unit in the solvent supply channel for its locking when the container weight increases by a value corresponding to the weight of the supplied component, the value of which corresponds to the set weight. Hydraulic pump outlet is communicated via filter and shut-off device with mixer container for return to tank in mode of circulation through filter of mixture coming from mixture discharge channel, and via shut-off unit is connected with ready mix discharge line.

EFFECT: increased operational efficiency is achieved through guaranteed accurate weighing of the liquid component to ensure the composition of the mixture by weight and percentage content of the components in the recipe.
