Technical Field

[0001] The utility model relates to the technical field of high-temperature molten salt, in particular to a high-temperature molten salt electrodeposition device. Background Art

[0002] The working principle of high-temperature molten salt electrodeposition equipment is mainly based on the electrochemical deposition process; in molten inorganic salts, by applying appropriate voltage, ions containing carbon or other elements are decomposed near the electrode and deposited onto the substrate to form the desired coating; in this process, the substrate usually acts as the cathode, and an inert electrode or an electrode of a specific material acts as the anode.

[0003] When the existing device is in use, the cathode substrate is usually sunk into the inner cavity of the graphite crucible and contacts the salt solution in the graphite crucible. After the power is turned on, the metal cations in the solution are deposited on the cathode surface connected to the negative pole of the power supply. However, this electrodeposition process needs to be carried out under constant temperature conditions. For this reason, the temperature in the device needs to be precisely controlled to avoid the influence of temperature fluctuations on the deposition process. Before the device is put into use, the electrodeposition device also needs to be fully inspected to ensure that the equipment is intact and can operate normally. Therefore, a high-temperature molten salt electrodeposition device that solves the above problems is needed. Summary of the Invention

[0007] As a preferred technical solution of the present invention, the air inlet pipe extends into the inner cavity of the reactor, and the air valve controls the flow rate in the inner cavity of the air inlet pipe.

[0008] As a preferred technical solution of the present invention, the air outlet pipe is arranged at the opposite end of the air inlet pipe, and the inner cavity of the air outlet pipe is connected to the outside.

[0009] As a preferred technical solution of the present invention, there are two temperature detectors, and the temperature detectors are respectively located on the outer walls of the reaction kettle and the middle cooling kettle.

[0010] As a preferred technical solution of the present invention, two connecting wires are connected to the outer wall of the power supply device, and the power supply device is respectively connected to the negative pole and the anode pole through the connecting wires.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The high-temperature molten salt electrodeposition device, through the coordinated use of the air pressure detector, gas cylinder, air outlet pipe, and closing head on the device, enables the gas cylinder on the device to block the closing head in the inner cavity of the air inlet and outlet pipe when outputting gas to the inner cavity of the reactor and the middle cooling kettle, and uses the air pressure detector to detect the air pressure in the inner cavity of the reactor and the middle cooling kettle. Therefore, when the device needs to be sealed before being put into use, the air pressure data reflected by the air pressure detector can be used to obtain information on whether the device as a whole is intact, and then the device can continue to be used normally for electrodeposition work.

[0013] 2. The high-temperature molten salt electrodeposition device uses the temperature detector, reactor, middle cooling kettle and power supply equipment on the device in coordination with each other, so that the two temperature detectors on the device are electrically connected to the power supply equipment, and the two temperature detectors are respectively installed on the outer walls of the reactor and the middle cooling kettle, and the inner cavity temperature of the reactor and the middle cooling kettle is monitored in real time. The temperature detector is used to ensure that the device is operated under constant temperature conditions during the electrodeposition operation, so that the temperature detector on the device monitors the temperature of the inner cavity of the device in real time to keep it in a constant temperature molten state. If the temperature is unstable, the power supply equipment automatically triggers the positive and negative current correction operation, thereby performing precise temperature control to avoid the influence of temperature fluctuations on the deposition process.
