Connect the vacuum pump's air port to the upper part of the separation tank and open the exhaust port to the water surface in the cooling water tank. The submersible pump's suction port is opened into the separation tank, and the discharge port is led out of the separation tank. , the reed switch is opened and closed by the submersible pump placed in the separation tank, and the reed switch is opened and closed by the reed switch actuator or the reed switch, and the pump motor pipe is electrically started and stopped by the opening and closing operation of the reed switch. Connected automatic driving system! When the vacuum pump is driven to create a vacuum inside the separation tank and water suction pipe, the liquid and sediment from the supply source flow into the separation tank, and the water level in the separation tank rises. The submersible pump is driven to discharge the liquid and sand from the discharge port to the outside of the separation tank, and the gas, which has been separated from the liquid and sand due to the gravity difference, is sucked into the inlet of the vacuum pump from the upper blade of the separation tank. At the same time, the vacuum pump is cooled during the process where the cooling water sucked from the water port and the water flow back into the cooling water tank from the exhaust port, and only the gas separated from the cooling water is brought to the surface of the water. If the water level in the separation tank falls, the submersible pump will stop and the discharge action from the discharge port will be interrupted, causing the vacuum pump to rise and the water level in the separation tank to rise. When the water rises, the submersible pump is driven again to start discharging from the discharge port.

The main body of the device of the present invention can be collected from a remote supply source 4 by simply extending the water suction hose without any transfer by the tt installed at the location, allowing it to be used inside narrow tunnels. It is possible to perform water suction work in places where ordinary pumps cannot enter, and the space around the work is wide, resulting in good work efficiency. In addition, muddy water can be discharged to a remote location where a business is closed simply by extending the discharge hose, and since the discharge work is carried out consistently and continuously with the above-mentioned collection work, it is possible to save time during work! 1 significantly shortened 1
Since it is an RC system, it eliminates the trouble of collecting muddy water and transporting it out of the mine using a trolley, which is required in the past, making it extremely efficient. In this way, the advantage is that work that conventionally required a large number of people can be done in a short time by a very small number of people. In addition, since a cooling effect is produced by circulating cooling water at the same time as the muddy water is collected by the vacuum pump 1, it can withstand continuous operation for a long time. Then, the submersible pump 2 starts up w′J at a predetermined water level in the separation tank 2.
The start of muddy water discharge by , stopping the submersible pump 2 when the water level is low, and restarting the submersible pump 2 by #VC after the water level is low.
It is very convenient because it is done automatically.
