Technical field
The utility model relates to a kind of colloid e Foerderanlage, and especially a kind of combined on site that can reduce transporting resistance loads in mixture emulsion explosive and carries damping device.
Background technology
Present on-site mixed emulsion explosive production system is extensive use of in mine such as mining, water conservancy and hydropower, railway traffic and infrastructure construction field blasting operation project.With onboard system it is prepared into explosive continuously after site mixed emulsified explosive car loading explosive starting material or work in-process sail the blasting operation scene into, and finishes blast hole charging, realize mechanize, the high-efficiency homework of explosion.At present, vehicle made emulsification blasting all adopts the curved bar pump to carry out pumping, is delivered to the mode of bottom, big gun hole by loading hose.From safety with guarantee the quality of explosive aspect, require explosive viscosity, loading pressure, loading hose diameter and the fed distance of site mixed emulsified explosive car pumping system all can not be too big, specific requirement is that explosive viscosity must not be greater than 3 * 10
4MPa.s, loading pressure must not surpass 1.5Mpa, and the loading hose diameter must not must not surpass 30m less than 50mm and fed distance.To increase water content in the explosive owing to reduce explosive viscosity, the explosive shelf lives is reduced, and can cause accident such as miss-fire when serious, and cause security incident easily by the increase pumping pressure.
Therefore the shortcoming of prior art is: carry the explosive resistance big, the explosive fed distance is short, and explosive that can only transport viscosity is big, water content is high makes the explosive shelf lives reduce, and can cause accident such as miss-fire when serious; Loading pressure is big, causes security incident easily.
The utility model content
The purpose of this utility model provides a kind of combined on site of explosive viscosity influence that is not subjected to and loads in mixture emulsion explosive conveying damping device.
For achieving the above object, the utility model is explained a kind of combined on site and is loaded in mixture emulsion explosive conveying damping device, its key is: comprise housing, inner sleeve and locking joint, described housing is that an end is the through-pipe structure of counterbore, described inner sleeve is installed in this housing, the pipe flange of this inner sleeve one end leans against on the counterbore step surface of described housing, has annular groove in the shell inner surface of suit inner sleeve, and this annular groove is looped around on the described inner sleeve tube wall; On described housing outer wall the sensitizing agent interface is installed, this sensitizing agent interface communicates with described annular groove; Described locking joint one end stretches in the counterbore of described housing and is threaded with housing, is against on the described inner sleeve bottom this locking joint, this inner sleeve is pressed on the step surface of described housing.
Described inner sleeve and described housing are for movingly, and described inner sleeve is positioned at the diameter of annular groove leading portion greater than the diameter that is positioned at this annular groove back segment, and the gap between described inner sleeve back segment and the described housing forms the pendular ring district, and this pendular ring district communicates with described annular groove.
The pendular ring district that forms between inner sleeve back segment and the housing is the ebb interval excessively of 0.4～1.2mm between inner sleeve and the housing, the feeding opening of this device is connected with the medicine outlet end of carrying explosive device, the medicine outlet of this device connects loading hose, emulsion explosive is pumped in the through hole of housing by loading in mixture emulsion explosive car curved bar pump, the sensitizing agent aqueous solution is pumped to the sensitizing agent interface by 1 2J (M) XF type duplex volume pump, the sensitizing agent aqueous solution enters annular groove by the sensitizing agent interface, and enter the pendular ring district that is communicated with this annular groove by annular groove, the sensitizing agent aqueous solution that has just flowed out the pendular ring district contacts with emulsion explosive in the through hole of the second stage of housing, sensitizing agent aqueous solution bag is tied up on the emulsion explosive surface, under pressure, flow forward together, because the sensitizing agent solution density has only 1.1g/cm
3Flow characteristics is almost consistent with water, stoped contacting of emulsion explosive and tube wall fully, sensitized reaction further takes place in free ammonium nitrate in the emulsion explosive surface and the Sodium Nitrite in the sensitizer solution simultaneously, produce a large amount of micro-bubbles on mobile emulsion explosive surface, formation gas-liquid ring continues coating emulsion explosive and flows in pipeline, friction resistance is reduced greatly, effectively reduce the explosive transporting resistance, and be not subjected to the restriction of explosive viscosity, pumping pressure, loading hose caliber, and the explosive fed distance is longer.
This apparatus structure is simple, and mounting, commissioning and maintenance is convenient, and is safe and reliable, according to the type difference of carrying explosive, selects the inner sleeve of different size for use, and implement device is to the transmission of dissimilar emulsion explosives, and adaptability is stronger.
Between described locking joint bottom and the described inner sleeve pipe flange first wear ring is installed, between the step surface of described inner sleeve pipe flange bottom surface and described housing counterbore second wear ring is installed.
The effect of first wear ring and second wear ring is to make housing, inner sleeve and locking joint three tightly fit together, and guarantees the pressure of loading.
The diameter of bore of described inner sleeve equates with the diameter of bore of described locking joint.Further reduce transporting resistance, make things convenient for the conveying of explosive.
Unusual effect of the present utility model is: simple in structure, easy to use, the explosive transporting resistance is little, be not subjected to the restriction of explosive viscosity, pumping pressure, loading hose caliber, and the explosive fed distance is longer.
