Description

[Detailed Description of the Invention] This invention relates to a dispensing device that continuously dispenses ore that has been slurried and stored in an ore storage pond.

Since powdered ore easily generates dust, it is typically stored or transported by adding water to the powdered ore to form a slurry. Generally, an ore storage pond is provided for storing ore, but as a method for discharging slurry from this ore storage pond, 1. A beam is placed over the ore storage pond, and both ends of the beam are installed on this. A trolley equipped with a dredge pump is mounted on the beam and can be moved freely along the rails laid on both sides of the ore storage pond via wheels, and the dredge pump and the transport pipe are connected. Dispense slurry.

2. A dredge ship is floated on the ore storage pond, and the dredge device of the dredge ship is used to discharge slurry by arranging a transport pipe toward the ground.

However, in the former case, in order to transfer the slurry transported by the dredge pump installed on the movable trolley to the transport pipe on the ground, receiving ports must be provided at several locations as the movable trolley moves. In order to change the inlet joint, it is necessary to stop the pump for a considerable period of time.

In addition, the latter requires many receiving ports like the former, and the ore storage pond must have a certain depth in order to keep the drudgery vessel dry, which reduces the amount of ore that can be released. There is.

The present invention was devised to solve this problem, and consists of forming an ore storage pond in a circular or fan shape, and installing a beam over the center and periphery of the ore storage pond. The center side of the ore storage pond is supported so as to be able to rotate, and the side around the ore storage pond is supported so as to be able to swing freely along the periphery of the ore storage pond through wheels provided thereon. A trolley is mounted, the trolley is bent in the middle, and one end is connected by a pin to the other end of a folding link which is connected by a pin to the center side of the ore reservoir of the beam, and a drudger pump is suspended from the trolley, The transport pipe of the dredge pump is supported on a folding link from the trolley and is disposed toward the center of rotation of the beam, thereby providing an efficient slurry dispensing device. The embodiments shown in the drawings will be described below.

In FIGS. 1 and 2, reference numeral 1 is a circular ore storage pond installed on the ground, and a fixed pedestal 2 is fixedly installed in the center of the ore storage pond 1. A shaft 3 is provided. Reference numeral 4 denotes a beam suspended above the ore storage pond 1, and a swing bearing 5 fitted to the swing shaft 3 is attached to the center end of the ore storage pond 1. Wheels 7 that run on rails 6 laid along the circumference of the ore storage pond 1 are provided at the ends. Therefore, beam 4 is the ore storage pond 1
It is possible to turn over the ore storage pond 1 using the center as the turning center.

8 is a trolley that can freely run on the beam 4 by a drive device (not shown); 9 and 9' are connected to each other with pins and bent in the middle, and one end is attached to the center side of the ore storage pond 1 of the beam. The trolley 8 is a pin-connected folding link, and the trolley 8 is pin-connected to the other ends of the folding links 9, 9', and is connected to a fixed part at the pivot center end of the beam 4. Reference numeral 10 denotes a dredge pump, which is suspended from the trolley 8 by a hoisting device 11 provided on the trolley 8 so that its height can be adjusted.

The transport pipe 12 connected to the dredge pump 10 is supported on the folding links 9, 9' from the trolley 8, guided to the center of rotation of the beam 4, and connected via a rotary joint 13 provided on the fixed frame 2. and is connected to the ground transportation pipe 14.

The folding links 9, 9' are automatically folded as the trolley 8 travels, and the transport pipe 12 supported by them is always kept on the beam 4 regardless of the travel position of the trolley 8. It is designed to provide support to prevent sagging.

The present invention is constructed as described above, and its operation will be described next. The dredge pump 10 suspended from the trolley 8 is stopped on the water surface at a predetermined position by turning by driving the wheels 7 of the beam 4 and by operating the trolley 8 to travel. Next, the water depth of the dredge pump 10 is determined by operating the hoisting device 11. When the dredge pump 10 is driven, the slurry is sucked into the dredge pump 10 and is fed from the transport pipe 12 to the ground transport pipe 14 via the rotary joint 13.

Now, the dredge pump 10 can be moved throughout the entire area of the ore storage pond 1 by the rotation of the beam 4 and the running of the trolley 8, and the winding of the hoisting device 11,
Water depth can also be adjusted by unwinding. Furthermore, no matter where the dredge pump 10 is located, the transport pipe 12 is guided to the center of rotation of the beam 4 without sagging on the beam 4, and the rotary joint 1
Since it is connected to the surface transport pipe 14 through the pipe 3, the present invention allows slurry to be continuously discharged and transported from the entire area of the ore storage pond 1, and the operation can be stopped and the transport pipe replaced. This has the effect of enabling highly efficient dispensing work without requiring much effort.

In this example, the ore storage pond is circular, but it may be semicircular or fan-shaped. Also, although rails and running wheels are used for turning the beam, trackless tire wheels may also be used. There is no problem.
