[0034] Please refer to Figure 1 - Figure 2 。

[0035] Some embodiments of the present application disclose a chloride salt turnover device, including a sealed container 1. The sealed container 1 is a container that is not in communication with the outside world, and the outside air cannot enter the sealed container 1. The sealed container 1 contains chloride salt and can achieve the isolation of the chloride salt from the external environment.

[0036] The chloride salt is turned over through the sealed container 1, which can avoid the chloride salt absorbing moisture from the external environment and getting damp during the turnover process. At the same time, it can avoid the chloride salt reacting with air during the turnover process and ensure the purity and dryness of the chloride salt after being turned over by the chloride salt turnover device.

[0037] The sealed container 1 is provided with a feed pipe 2, a discharge pipe 3, a regulating assembly and a heater.

[0038] The sealed container 1 is docked with the drying equipment through the feed pipe 2, and the dried chloride salt prepared by the drying equipment is fed into the sealed container 1 through the feed pipe 2. A feed valve is provided on the feed pipe 2, and the sealed container 1 controls whether it is connected to the outside through the feed pipe 2 by opening and closing the feed valve. Specifically, when the drying equipment feeds the sealed container 1, the feed valve is opened, and the sealed container 1 is connected to the drying equipment through the feed pipe 2; when the drying equipment stops feeding the sealed container 1, the feed valve is closed, and the sealed container 1 is not connected to the outside, so as to prevent outside air from entering the sealed container 1 through the feed pipe 2 after the feed stops.

[0039] The sealed container 1 is docked with the salt addition port of the electrolytic furnace through the discharge pipe 3, and the chloride salt in the sealed container 1 is discharged into the electrolytic furnace through the discharge pipe 3. A discharge valve is provided on the discharge pipe 3, and the sealed container 1 controls whether it is connected to the outside through the discharge pipe 3 by opening and closing the discharge valve. Specifically, when the sealed container 1 discharges materials to the electrolytic furnace, the discharge valve is opened, and the sealed container 1 is connected to the salt addition port of the electrolytic furnace through the discharge pipe 3; when the sealed container 1 stops discharging materials to the electrolytic furnace, the discharge valve is closed, and the sealed container 1 is not connected to the outside, so as to prevent outside air from entering the sealed container 1 through the discharge pipe 3 after the discharge stops and to prevent leakage of materials from the sealed container 1.

[0040] When the drying equipment feeds the sealed container 1, the discharge valve is closed, and when the sealed container 1 discharges materials to the electrolytic furnace, the feed valve is closed.

[0041] A regulating assembly is provided on the sealed container 1 for regulating the gas pressure inside the sealed container 1. Specifically, when the drying equipment feeds the sealed container 1, the feed pipe 2 is docked with the discharge port of the drying equipment, and the gas pressure inside the sealed container 1 is regulated through the regulating assembly so that the gas pressure inside the sealed container 1 is consistent with the gas pressure of the drying equipment; when the sealed container 1 discharges materials to the electrolytic furnace, the discharge pipe 3 is docked with the salt addition port of the electrolytic furnace, and the gas pressure inside the sealed container 1 is regulated through the regulating assembly so that the gas pressure inside the sealed container 1 is consistent with the gas pressure inside the electrolytic furnace.

[0042] It should be noted here that the gas pressure inside the sealed container 1 being consistent with the gas pressure of the electrolytic furnace or the drying equipment does not require the gas pressure of the sealed container 1 to be exactly equal to the gas pressure of the electrolytic furnace or the drying equipment. There can be a pressure difference between the gas pressure of the sealed container 1 and the gas pressure of the electrolytic furnace or the drying equipment that does not affect feeding and discharging. More specifically, the gas pressure of the sealed container 1 can be higher or lower than the gas pressure of the electrolytic furnace or the drying equipment.

[0043] The adjusting assembly can not only adjust the gas pressure in the sealed container 1, but also displace the gas in the sealed container 1 through the inlet pipe and the outlet pipe according to the requirements of the gas environments of the drying equipment and the electrolytic furnace.

[0044] The adjustment of the gas pressure in the sealed container 1 by the adjusting assembly is not limited to adjusting the gas pressure in the sealed container 1 to be consistent with the gas pressure in the drying equipment or the electrolytic furnace, but can also evacuate the sealed container 1.

[0045] The heater of the sealed container 1 is used to heat the sealed container 1 to reduce the temperature difference between the sealed container 1 and the chloride salt discharged from the drying equipment.

[0046] When the sealed container 1 is not heated, the temperature of the sealed container 1 is the ambient temperature, and the temperature of the chloride salt discharged from the drying equipment is above 100°C. If the chloride salt is directly discharged into the unheated sealed container 1, the high-temperature chloride salt will adhere to the wall of the sealed container 1, and as the service time prolongs, the amount of adhered chloride salt will increase, which requires the staff to clean the wall of the sealed container 1, increasing the labor intensity. In this solution, the sealed container 1 is heated by the heater so that the temperature of the sealed container 1 is close to the temperature of the chloride salt supplied by the drying equipment, so as to minimize the adhesion of the chloride salt on the wall of the sealed container 1. There is no need for manual cleaning of the chloride salt turnover device, which not only reduces the labor intensity, but also does not affect the continuous progress of molten salt electrolysis. The chloride salt turnover device disclosed in this application includes a sealed container 1. Through the sealed container 1, the isolation between the chloride salt and the external environment is realized during the turnover process, so that the chloride salt does not contact with air during transportation, reducing the risk of moisture absorption and oxidation of the chloride salt, ensuring the purity and dryness of the chloride salt transferred to the electrolytic furnace. At the same time, the gas pressure in the sealed container 1 is adjusted by the adjusting assembly so that the sealed container 1 adapts to the atmosphere of the drying equipment and the electrolytic furnace, avoiding adverse effects on the chloride salt in the drying equipment and the electrolytic furnace during feeding and discharging while ensuring smooth feeding and discharging, ensuring the purity and dryness of the chloride salt, and enabling the molten salt electrolysis to proceed smoothly.

[0047] The adjusting assembly includes an inlet pipe 4, an exhaust pipe 5 and a pressure gauge 6. An inlet valve is provided on the inlet pipe 4, an exhaust valve is provided on the exhaust pipe 5, and the pressure gauge 6 is used to collect the gas pressure in the sealed container 1 in real time.

[0048] The inlet pipe 4, the exhaust pipe 5 and the pressure gauge 6 are all installed on the sealed container 1 and communicate with the inner cavity of the sealed container 1.

[0049] When the pressure in the sealed container 1 is lower than the pressure of the drying equipment or the electrolytic furnace docked with the sealed container 1, open the intake valve and close the exhaust valve, and fill the sealed container 1 with gas until the gas pressure of the sealed container 1 collected by the pressure gauge 6 is equal to the pressure of the drying equipment or the electrolytic furnace, then close the intake valve; when the pressure in the sealed container 1 is higher than the pressure of the drying equipment or the electrolytic furnace docked with the sealed container 1, open the exhaust valve and close the intake valve, and discharge the excess gas in the sealed container 1 until the gas pressure of the sealed container 1 collected by the pressure gauge 6 is equal to the pressure of the drying equipment or the electrolytic furnace, then close the exhaust valve.

[0050] During the operation of the chloride salt turnover device, once the pressure in the sealed container 1 is inconsistent with the pressure of the drying equipment or the electrolytic furnace, the pressure of the sealed container 1 of the chloride salt turnover device is adjusted in real time by controlling the intake valve and the exhaust valve to ensure the smooth feeding and discharging of the chloride salt turnover device.

[0051] The adjusting assembly not only adjusts the gas pressure of the sealed container before feeding and discharging, but also can adjust the gas pressure of the sealed container during the feeding and discharging process.

[0052] Therefore, it is necessary to collect the gas pressure in the sealed container 1 in real time through the pressure gauge 6 and adjust the pressure of the sealed container 1 according to the pressure difference between the sealed container 1 and the drying equipment and the electrolytic furnace.

[0053] The chloride salt is a solid material. It is preferred to set the feeding pipe 2 on the top wall of the sealed container 1. The chloride salt falls into the sealed container 1 from top to bottom, and finally the sealed container 1 can be filled with chloride salt, increasing the single turnover volume of the chloride salt.

[0054] Considering that during the feeding process of solid materials, a conical surface will be formed on the upper layer of the solid materials. In order to make the chloride salt fill the sealed container 1 and prevent the chloride salt from being pumped out of the sealed container during vacuum pumping, the top wall of the sealed container 1 in this solution is selected as an arc wall adapted to the conical surface formed by the falling of the chloride salt.

[0055] The top wall of the sealed container 1 can also be conical.

[0056] In the embodiment where the sealed container 1 is an arc wall, the feeding pipe 2 is preferably arranged at the highest position of the arc wall.

[0057] In order to enable all the chloride salt to be discharged from the sealed container 1, the discharge pipe 3 is arranged on the bottom wall of the sealed container 1 with the lowest position in this solution.

[0058] The bottom wall of the sealed container 1 is an arc wall or a conical wall, and the feeding pipe 2 is arranged at the lowest position of the bottom wall. The arc-shaped or conical bottom wall can play a guiding role in the feeding of the chloride salt to discharge all the chloride salt in the sealed container 1 out of the sealed container 1.

[0059] The middle part of the sealed container 1 can be cylindrical or prismatic. Correspondingly, the shapes of the top wall and the bottom wall are adapted to the shape of the middle part of the sealed container 1.

[0060] For the convenience of storing the sealed container 1, the chloride salt turnover device disclosed in this application further includes a support frame 7, and the sealed container 1 is installed on the support frame 7 so that the sealed container 1 maintains an upright state.

[0061] The upright state of the sealed container 1 is the working state when the sealed container 1 is docked with the drying equipment or the electrolytic furnace, so that the sealed container 1 does not need to be adjusted when it is docked with the drying equipment or the electrolytic furnace, reducing the docking difficulty;

[0062] At the same time, as Figure 1 and Figure 2 shown, the dimension of the sealed container 1 in the vertical direction is greater than the dimension of the sealed container 1 in the horizontal direction. The sealed container 1 is placed in an upright state, which can reduce the occupied space of the chloride salt turnover device during storage and transportation;

[0063] In addition, the sealed container 1 is supported by the support frame 7, enhancing the stability of the sealed container 1 placed upright.

[0064] The sealed container 1 and the support frame 7 can be detachably connected, so that when the sealed container 1 needs to be docked with the drying equipment or the electrolytic furnace, only the sealed container 1 needs to be carried, and there is no need to carry the support frame 7 synchronously, so as to reduce the intensity and difficulty of carrying.

[0065] Only one sealed container 1 can be installed on the support frame 7, or at least two sealed containers 1 can be installed.

[0066] The sealed container 1 and the support frame 7 can also be fixedly connected to ensure the stability of the sealed container 1 after being docked with the drying equipment or the electrolytic furnace.

[0067] As Figure 1 and Figure 2 shown, the support frame 7 includes a vertical support frame and a horizontal support frame. One end of the vertical support frame is located on the ground, and the other end of the vertical support is connected to the horizontal support. The sealed container 1 is vertically placed on the horizontal support.

[0068] The vertical support frame includes a plurality of vertical support rods arranged along the circumference of the sealed container 1. The horizontal support frame is arranged along the outer circumference of the sealed container 1. The lower surface of the horizontal support frame is connected to the vertical support rods, and the horizontal support frame has a connecting rod for connecting with the outer wall of the sealed container 1.

[0069] The support frame 7 can be integrally cubic or cylindrical. The shape of the support frame 7 can be the same as or different from the shape of the sealed container 1.

[0070] To enhance the flexibility of the chloride salt turnover device during ground movement, the present application is provided with rollers 8 below the support frame 7, and the support frame 7 moves on the ground through the rollers 8.

[0071] The sealed container 1 of the chloride salt turnover device disclosed in the present application can not only isolate the chloride salt from the external environment, but also adjust its own pressure according to the air pressure of the drying equipment or the electrolytic furnace. To further optimize the above technical solution, the sealed container 1 of the chloride salt turnover device disclosed in the present application can also keep the chloride salt warm to reduce the temperature loss of the chloride salt in the sealed container 1.

[0072] In some embodiments of the present application, the sealed container 1 includes an inner cylinder and an outer cylinder, and a heat preservation layer and a heater are arranged between the inner cylinder and the outer cylinder to enable the sealed container 1 to have a heat preservation function. The thickness of the heat preservation layer is 50 mm - 100 mm, and the density of the heat preservation layer is 12 Kg / m 3 - 48 Kg / m 3 .

[0073] The heater is an electric heater or a coil heater, etc.

[0074] The heat preservation material selected for the heat preservation layer can be one or several of aluminum silicate heat preservation cotton, alumina heat preservation cotton, rock wool or glass wool.

[0075] The inner cylinder of the sealed container 1 needs to have a certain corrosion resistance. In some embodiments of the present application, the inner cylinder is made of a corrosion-resistant metal material. Preferably, the corrosion-resistant metal is stainless steel 316L, 310S or 2507.

[0076] Considering the working environment and use of the sealed container 1, preferably, the outer cylinder also needs to have corrosion resistance. In some embodiments of the present application, the outer cylinder is made of a corrosion-resistant metal material. Preferably, the corrosion-resistant metal is 316L stainless steel.

[0077] The thicknesses of the inner cylinder wall and the outer cylinder wall are determined according to the storage volume.

[0078] The gas in the sealed container 1 is an inert gas.

[0079] The chloride salt turnover device disclosed in the present application can timely supplement chloride salt into the electrolytic furnace to achieve continuous electrolysis without stopping the furnace. Transfer the pre-dried and heat-preserved chloride salt to the electrolytic furnace under an inert gas or vacuum state, and timely supplement chloride salt to the electrolytic furnace to improve the electrolysis efficiency and the economy of the electrolytic product titanium metal.

[0080] During the turnover process of the chloride salt turnover device disclosed in this application, it can not only be isolated from the external environment during the turnover process, but also be isolated from the external environment during feeding and discharging, ensuring the stability of the chloride salt.

[0081] The feed inlet is aligned with the discharge port of the drying equipment, and the discharge outlet is aligned with the feed inlet of the electrolytic furnace.

[0082] The above description is only for the preferred embodiments of this application and the explanation of the applied technical principles, and is not used to limit this application. For those skilled in the art, this application can have various changes and modifications. The scope of the application involved in this application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above application concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) having similar functions disclosed in this application.
