Abstract

The proposal addresses a device for cleaning mine drainage chutes from sludge and silt. The device consists of a mine locomotive equipped with a hydrogen generator and a working fluid tank, connected to a collection car. The chassis of the collection car is equipped with a collection pressure vessel with an intake and discharge opening, a suction and a vacuum pump - compressor equipped with a hydraulic motor. The device travels along the track and, using the suction effect of the vacuum pump - compressor, sucks sludge and silt from the drainage chutes into the collection vessel. The sucked-in sludge and silt are transported and expelled by overpressure to their destination.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning mine dewatering sludge and alluvia for use in rail mining.

So far, the mine trenches draining the mine railways from the sludge and alluviums that they impose have been mainly done by hand, which is a laborious task that binds a significant number of workers. Sludge pump cleaning is poorly effective and imperfect, bucket chain cleaning is also less efficient and is limited by the cramped mine space and irregular drainage configuration.

The aforementioned drawbacks are eliminated by the dewatering mine cleaning apparatus according to the invention, consisting of a mine locomotive equipped with a hydraulic generator and a working fluid tank and an associated collection wagon.

SUMMARY OF THE INVENTION The subject of the invention is that the attached collection wagon, which is provided with a pressure receptacle with a suction and discharge opening provided with a suction and a vacuum pump equipped with a hydraulic motor, is connected by a mechanical coupler and pressure working fluid line to a mining locomotive. The collecting tank may be hinged to the bogie chassis with pivots, eyes and a hydraulic cylinder.

With the device according to the invention, virtually all mine shavings can be cleaned of sludge and alluvia irrespective of the shank configuration, with low consumption of live human labor and with sufficient power.

In the accompanying drawing, an exemplary embodiment of an apparatus for cleaning a drainage mine according to the invention is shown schematically in a side view.

The device for cleaning the dewatering mine trunks consists of a connected collection wagon 2 and a mining locomotive 2 interconnected by a mechanical coupler 2 ^{and a} line 2 of a pressurized working fluid. T_ mine locomotive engine 2, which is provided with a working fluid tank 2 is force and the pump 2 · collecting pressure vessel 2 is connected a collecting vehicle 2 ^e j provided with intake and discharge port 10 with the closure elements 11 and 12. Further Savic pump compressor 13 frictionally coupled with the hydraulic motor 24. The collecting vessel 2 can be hinged to the chassis 2 of the connected collecting wagon 2 by means of pins 25, lugs 16 and a hydraulic cylinder 17.

Pa motor 2 mine locomotives 2 j ^e driven hydrogenerator 5 which draws from the tank 2 a liquor via line £ supplying pressurized working fluid, a hydraulic motor 14 which drives the pump - compressor 13 either so that it exerts in the collecting vessel 2. The vacuum thus is sucked through the suction hose 12 and the suction outflow opening 10 to the collecting mine sludges pressure vessel 2 ^and / or so that it exerts in the filled collecting vessel 2. the pressure and forces it through a suction outlet hole 10 and the suction hose 12 previously imbibed mining slurries.

The closure element 11 of the intake and discharge orifices 10 serves to prevent the mine sludge from flowing out of the full collecting pressure vessel 2 during transportation and further to generate sufficient vacuum in the empty collecting pressure vessel 2 prior to commencing suction of the sludge when it is also closed. When emptying the collecting tank 2 filled with mud sludge and alluvium with higher coarse particles, the depressurizing effect of the pressurized emptying can be supported by tilting the collecting tank 2 around the pins 15 by a hydraulic cylinder 17 also supplied with the mine locomotive 2 and after short-circuiting the line 4 of the pressurized working fluid, use it for its original purposes.

The equipment for cleaning sludge and alluvial mine dewatering ditches is suitable for use in mine rail transport in mines with a higher incidence of water and sludge., It is especially suitable for those mines that are equipped with either central sludge pits or pumping mine sludge to the surface. In these cases, another logical element of the complex sludge disposal in the mine due to the arrangement of the mine dewatering device is that the mine locomotive 2 can be quickly disconnected from the connected pick-up wagon 1 and its use for the original determination when mine sludge collection is not urgent. and vice versa, there is a need for a mining locomotive 2 for transportation purposes, which has a beneficial effect on the amount of purchase and operating costs of the mine machinery.
