    Apparatus for transporting solid particles from an underground excavation to a level above the ground has a liquid-containing underground vessel which receives solid particles from a conveyor or from lorries and whose lower portion communicates with the receiving ends of two U-shaped pipes having discharge ends connected to a riser. One receiving end is connected with a high-pressure pump for clear liquid when the other receiving end receives a mixture of solid particles and liquid from the vessel, and vice versa. Simultaneously, the discharge end of the pipe which receives clear liquid communicates with the riser to admit the (previously received) mixture of solid particles and liquid while the other discharge end communicates with the intake of a suction pump which delivers clear liquid to the vessel. The valves which control the admission of mixture or pressurized liquid into the pipes and the valves which control the admission of mixture into the riser and the flow of clear liquid from the pipes are rinsed with water or are automatically held out of contact with solid particles to reduce wear upon their parts. The pumps convey clear liquid so that the wear upon their parts is also negligible. A booster, whose operation is analogous to that of the transporting apparatus, is installed in the riser so that the latter can convey the mixture through a great distance, e.g., onto a conveyor located at or above the ground and serving to intercept particles.

    The invention relates to the field of hydrotransport of bulk materials, mainly coal and ore.
    A known installation for the hydraulic transportation of bulk materials * containing a mixing tank with an outlet, a loading apparatus, consisting of two pipes, the inlets of which are connected to a high-pressure pump and a mixing tank, and the outputs - to a transport pipeline, a suction pump and shut-off valves valves mounted at the inlets and outlets of said pipes.
    The disadvantage of this installation is that the suction pump and shut-off valves, through which the mixture of liquid and bulk material flows, constantly in contact with the material, undergo rapid wear and tear, which in turn leads to the fragility of the entire installation.
    The purpose of the invention is to increase the durability of the installation. 25
    This is achieved by the fact that the mixing tank has two outlet openings made in its bottom to which the pipe inlets are connected, and the pipe outlets are connected to the suction pump by means of shut-off valves mounted on them and connected to the pipe connection to the transport pipeline item.
    The drawing shows the proposed installation, General view.
    The installation contains an underground mixing tank 1, which is loaded through a conveyor belt 2 transported bulk material (coal or ore). The bottom of the tank 1 has two outlet openings connected to the inlets of the pipes 3 and 4, forming a loading apparatus 5. The outlet openings are equipped with two automatically activated shutters 6 and 7, which in the open position provide loading of the pipes 3 and 4, and in the closed position - their connection with pipelines 8 and 9 of the high-pressure pump 10. Pipelines 8 and 9 are equipped with shut-off valves 11 and 12 with rotary dampers. A transport pipeline 13 is connected to the exits of the pipes 3 and 4 of the loading apparatus, and a switching element 14 is installed at the place of their connection. In addition, the exits of the pipes 3 and 4 are connected via the suction pump 1 'through the controlled shut-off valves 15 and 16 to the filling tank 1 8. The element 14 is included in the sump 19, equipped with a device 20 for removing material. The sump 19 through the return pipe 21 is connected to the pump
    10.
    To collect the water available in the mines, pipe 22 is used, which is connected to the collector 23, and to extract water from the collector 23, a sump pump 24 is connected to the return pipe 21. The valve 25, which is controlled depending on the water level in the collector 23, is used to control 5 ka, transported by a bilge pump 24. A return line through a pipe 26 is connected to a tank 1. Located on the pipe 26 and controlled depending on the water level in the tank 1, the valve 27 opens when the water level is too low and allows water and From the return pipe 21, drain into the tank 1. The bypass pipe 28 of the container 1 is included in the collection 23. By means of these additional devices, the water available in the mines can be used for transportation in a simple way and eliminates the need for an additional drainage device. If a sufficient amount of water is formed in the mine, then the need for returning water from the surface of the earth decreases and the necessary amount of water is taken from the mine water. The partition 29 located in the tank 1 is used to prevent accidental ingress of transported large pieces into the pipeline 26 and pipe 28. The valve 30 is used only for safety. A pipe 31 is designed to drain excess mine water. '
    Installation works as follows. 45
    Transported bulk material using a conveyor belt 2 is fed into a container containing water 1.
    Pumps 18 and 10 are in operation. The pump 10 delivers clean water through the pipe 8, the open valve flap 12 and the shutter 6 in the closed position to the pipe 3. At the same time, the suction pump 18, thanks to the open valve 15, draws the clean water in the pipe from the previous cycle into the tank 1, at the bottom of which the shutter is open 7. The feed of material reaches the end of the pipe 4, valves 15 and 12 located in clean water are closed, and valves 16 and 11, also in pure water, open. Water is supplied to the pipe 4 through the pipe 9. The flaps 6 and and the switching element 14 due to the changed pressure conditions are automatically switched. The entrance to the pipe 4 is closed by a shutter 7, and the entrance to the pipe 3 is opened by a shutter b. Pressure water now pumps the mixture of water and bulk material in the pipe 4 through the open and locking pipe 3 switching element 14 into the transport pipe 13, from where it enters the sump 19, from which the device 20 removes solids.
    Water free of solids through the return line 21 enters the pump 10. While the mixture of liquid and solids with pure water is pumped from the pipe 4, the pipe is filled in the manner described above.
    Due to the synchronous switching of the valves 11, 12, 15 and 16, the pressure ratios in the charging device 5 change, causing, from the whole side, the position of the shutters and 7 under the tank 1 and the switching element 14 to change. If this is the flow of transported material pumped by the pump 10, which simultaneously acts as the wash flow, choose larger than the flow of the suction pump 18, then the switching element 14 switches at the moment when pure water flows through it. Both shutters 6 and under tank 1 are flushed with clean water at the time of switching to prevent wear or stuck solids. It is also possible with a short interruption in the supply of solids to ensure that the shutters b and 7 are switched in clean water. Since the valves 15 and 16 are switched before the first solids in the filled pipe arrive at its end, it is not possible that the valves 15 and 16 and the suction pump 18 are in contact with solids, i.e. their wear is prevented and the overall durability of the entire installation is increased.
