Mixing and charging machine

The utility model relates to the operation of mines and quarries and can be used in open pit mining during blasting.

Known transport-charging machine according to A.S. No. 888622, which is intended for the transport of components of explosive material; to the well. The disadvantage of such a machine is that it delivers not finished explosives to the well, but only its components.

The closest technical solution to the proposed utility model is a charging machine according to A.S. No. 471448, which consists of a self-propelled chassis, bunkers for and liquid components of explosive material, material, a screw mixer with a drive, pumps, pipelines and a steam generator. The disadvantage of a charging machine according to A.S. No. 471448 in that. that it is impossible to prepare a multicomponent explosive on it.

The technical effect in obtaining a multicomponent explosive while improving its quality.

The technical effect is achieved by the fact that the mixing mechanism is represented by two conveyors located perpendicular to each other and interconnected by means of flanges, one of the conveyors being made obliquely, at an angle of 45 ° to the transverse vertical plane, and the emulsion and finished product feed pumps are placed across the transport base and installed in a thermally insulated compartment with forced supply of hot gas.

On fig shows a diagram of the mixing mechanism; figure 2 - diagram of the mixing mechanism (top view),

The mixing and charging machine consists of transport base 1, on which bunkers are placed: 2 for emulsion, 3 for nitrate, 4 for sodium nitrite (GTE) solution, 5 for diesel fuel of explosive components (BB) and hopper 6 for finished explosives. In addition, a screw pump 7 for supplying emulsion, connected to a static mixer 8, a pump 9 for supplying a GGD, a pump 10 for supplying diesel fuel, augers 11 for feeding saltpeter, an inclined conveyor 12 and a longitudinal conveyor 13 for mixing components, is ready for use on the transport base product BB 14 connected to the hopper 6, thermally insulated compartment 15.

The mixing-charging machine works as follows: when the control panel is turned on, which can be of any known design and is not shown in the drawing, the screws 11 from the hopper 3 start

5, the pump 10 also supplies diesel fuel to the conveyor 12, where they are mixed and an intermediate igdonite explosive is obtained. Received in an inclined conveyor igdonite enters the longitudinal conveyor 13.

At the same time, from the hopper 2 by gravity to the screw pump 7 is fed

the emulsion, where it is pre-mixed with the gas turbine engine, which is injected there by the pump 9. The final mixing takes place in the static mixer 8, into which both products are fed by the pump 7. From the static mixer 8, the emulsion mixed with the gas turbine engine enters the longitudinal conveyor 13, where the finished explosive takes place by mixing igdonite and a mixture of emulsion with GGD. After that, the explosive enters the hopper 6, from where the screw pump 14 delivers the explosive to charge the well. Throughout the process, the thermally insulated compartment 15, in which the pumps 7 and 14 are located, is heated by hot gases, such as exhaust gases.
