Description

Facility for melting and transporting the packed sodium (Liquid metal) having a function level}

The present invention relates to a melting and conveying apparatus for packaging sodium, and more particularly, to a melting and conveying apparatus for packaging sodium, which is capable of melting and conveying sodium in a packaged state and at the same time, checking the amount of conveyance through water level measurement. And a conveying device.

In general, sodium is extremely limited in use due to its properties and risks. In particular, in contact with oxygen in the atmosphere to produce a gaseous powder of the alkali oxide, when melting in the atmosphere may cause a metal fire, and when reacted with water has a strong explosion.

Such sodium has not been standardized in handling methods (especially melting and conveying) to date, but in general, solid sodium (Ingot) in a storage tank is pre-filled and sealed to heat the storage tank, or a package in which insulation is installed. The heater is installed outside the drum and melted.

However, since the solid storage of sodium in the storage tank is pre-sealed and the storage tank is heated, work must be performed externally until it is put into the molten-join storage tank, so that sodium is exposed to the air, resulting in fire and moisture contact. The risk of explosion and the formation of sodium oxide inside the device are likely to cause problems or blockage of the sodium flow path.

In addition, in the case of melting the heater by installing the heater outside the packing drum with the insulation, the process of disassembling the heater and sensor on the outside of the drum, keeping the warming work, and the transfer completed must be repeated. It is difficult to identify, and because the worker has to handle the heater and the insulation directly, it is difficult to keep the worker's safety from heat or harmful to human body, and the waste that is inevitably generated is a problem.

The present invention has been made to solve the above-mentioned drawback, at room temperature melting and transporting of sodium (liquid metal, hereinafter, sodium), which is solid, can be melted and transported without direct handling of sodium without exposure to outside air and sodium drum It is an object of the present invention to provide a melting and transporting device for packing sodium, which enables the transport amount of sodium to be checked by checking the remaining amount in the drum by the internal water level measuring device, and enables melting and transporting the sodium in a packing (drum) state. .

The configuration of the present invention to achieve the object as described above and to solve the conventional drawbacks is to insert the packaging (drum) sodium 30 into the furnace case 10 and the upper furnace case 20. A space for forming a drum, a heater 40 for drum heating is provided on the inner side and the lower side of the furnace case, a heater controller 50 is connected to the heater, and a drum pressure gas pipe for the upper furnace case. 60 and the sodium transport pipe 70 is coupled, the water level measuring device 80 is inserted into the packaging sodium, the temperature sensor 90 is attached to the side of the furnace case, the lower side outside the furnace case The wheel 100 for movement is provided.

Hereinafter, the configuration and the operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a device configuration diagram of the present invention, the interior of the melting furnace of the present invention to secure a space for inserting the packaging drum 30, the pressure tube 60 injects gas into the drum to the sodium inside the drum The gas is charged so as not to oxidize, or the pressure is released during the complete melting of the sodium, and the pressure is released to increase the pressure inside the drum due to thermal expansion when the drum is heated. The inside of the drum is inserted into the water level measuring device 80 to measure the remaining amount in the drum during transfer to check the transfer amount. Sodium transfer pipe 70 is a sodium flow path for supplying the molten sodium to the storage tank of the experimental apparatus by the pressure of the gas is composed of a pipe and a connecting pipe. The temperature sensor functions to check the melting state and temperature inside the drum by the temperature of sodium. The heater 40 inside the melting furnace is to be controlled separately, it can be controlled by an external controller.

The present invention is attached to the transfer wheel 100 to the lower portion of the device to minimize the transfer distance of sodium and move according to the position of the device as close to the required position to improve the maneuverability, the device configuration or operation relatively easy structure It is.

In addition, in the present invention, both the connection of the pressure pipe and the configuration of the sodium flow path are removable and easy to disassemble and assemble. There is a number.

The operation of the present invention connects the gas pipe and the sodium transfer pipe, and supplies the gas into the drum to fill the gas so that it does not come into contact with air, and then connects the sodium transfer pipe and inserts the tip of the transfer pipe into the drum to fix it. Check the operating status of the temperature sensor and heater controller and start the upper heater. When sodium is melted, it is heated to an equilibrium state to a temperature suitable for the whole transfer. Open the valve on the experimental device side for the transfer of sodium, slowly pressurize the inside of the drum to start the transfer of sodium, and adjust the pressure by adjusting the pressure. If you want to check the transport amount of sodium, you can check the indication value of the signal measuring device connected with the water level measuring device, and if necessary, adjust the feeding amount by adjusting the pressure.

Therefore, the present invention forms a space for inserting the packaging (drum) sodium 30 into the furnace case 10 and the upper furnace case 20, and for drum heating on the inner side and the lower side of the furnace case A heater 40 is provided, and a heater controller 50 is connected to the heater, and a drum pressure regulating gas pipe 60 and a sodium transfer pipe 70 are connected to the upper furnace case, and the inside of the packaged sodium It is inserted into the water level measuring device 80, the temperature sensor 90 is attached to the side of the furnace case, the movement wheel 100 is provided on the lower side of the outside of the furnace case, the solid at room temperature (liquid metal, It is possible to melt and transfer without exposing to the outside without direct exposure to sodium during melting and conveying of sodium), and it is possible to check the transfer amount of sodium by checking the remaining amount in the drum for the water level measuring device inside the sodium drum. Drums) As it may enable the melting and transfer.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.

The present invention constituted as described above, the melting and conveying apparatus of packed sodium suppresses the influx of impurities during handling of sodium and actively improves the risk during operation, so that the melting and conveying of the packed sodium is possible in the packing and transporting apparatus.
