[0046] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0047] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in this application are no longer described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] See also Figures 1 to 7 The embodiment of the present application provides an anode mud processing device 100, including a crucible 1, a furnace 2, a heating device 10, a feeding device 3 and a ventilation device 4, the crucible 1 is used to hold the anode mud; the furnace 2 forms a smelting chamber 2a; the heating device 10 is arranged in the smelting chamber 2a, and the heating device 10 is used to heat the anode mud in the crucible 1.

[0049] The crucible 1 can prevent the anode mud from contacting with the external environment and other devices and causing contamination. The heating device 10 heats the crucible 1 to convert the anode mud in the crucible 1 from powder to molten state.

[0050] The feeding device 3 includes a feeding port 3a, a feeding chamber 3b and a gate valve 31. The feeding port 3a is connected to the feeding chamber 3b. The crucible 1 enters and exits the smelting chamber 2a through the feeding chamber 3b. The gate valve 31 is used to open or cut off the path between the feeding chamber 3b and the smelting chamber 2a. The ventilation device 4 is used to evacuate the feeding chamber 3b and the smelting chamber 2a and replenish the protective gas.

[0051] When the gate valve 31 opens the path between the feed chamber 3b and the smelting chamber 2a, the feed chamber 3b and the smelting chamber 2a are in a connected state; when the gate valve 31 cuts off the path between the feed chamber 3b and the smelting chamber 2a, the feed chamber 3b and the smelting chamber 2a are in a closed state respectively.

[0052] Specifically, before the anode mud treatment equipment 100 smelts the anode mud, the gate valve 31 cuts off the path between the feed chamber 3b and the smelting chamber 2a, and the smelting chamber 2a is a closed chamber. The smelting chamber 2a is evacuated by the ventilation device 4, so that the vacuum degree in the smelting chamber 2a is less than 5×10 -4 Pa (Pascal), and the oxygen content in the smelting chamber 2a is lower than 5ppm (parts per million). The ventilation device 4 supplements the protective gas in the smelting chamber 2a, so that the smelting chamber 2a is in an inert environment to prevent the metal substances in the anode mud from reacting with oxygen to generate impurities.

[0053] After the environmental treatment in the smelting chamber 2a is completed or while the environmental treatment in the smelting chamber 2a is being performed, the crucible 1 containing the anode mud is placed into the feed chamber 3b through the feed port 3a, and the feed port 3a is closed, that is, at this time, the feed chamber 3b is a closed chamber, and the feed chamber 3b is evacuated and supplemented with protective gas through the ventilation device 4, so that the environments of the feed chamber 3b and the smelting chamber 2a are roughly the same, and the gate valve 31 is opened to conduct the path between the feed chamber 3b and the smelting chamber 2a, and the crucible 1 can enter the smelting chamber 2a from the feed chamber 3b. Subsequently, the gate valve 31 is closed to cut off the path between the feed chamber 3b and the smelting chamber 2a, and the crucible 1 cannot return from the smelting chamber 2a to the feed chamber 3b, and the anode mud treatment equipment 100 starts to operate. During the operation, the heat generated by the heating device 10 is difficult to diffuse outward, and the furnace 2 has a good heat insulation effect.

[0054] After the anode mud processing equipment 100 is completed, the anode mud is solidified into a block of metal ingots, the gate valve 31 is opened, and the crucible 1 can enter the feed chamber 3b from the smelting chamber 2a, then the gate valve 31 is closed, and the feed port 3a is opened to take out the block of anode mud for packaging, that is, a smelting process is completed. It can be understood that in the case where the anode mud needs to be smelted multiple times, each time the new anode mud is replaced, the path between the feed chamber 3b and the smelting chamber 2a can be cut off by the gate valve 31, and the smelting chamber 2a is basically not connected to the outside world, so that the smelting chamber 2a can be kept full of protective gas, and there is no need to repeatedly evacuate and replenish the protective gas of the smelting chamber 2a each time the new anode mud is replaced. The gas exchange device 4 only needs to evacuate and replenish the protective gas of the feed chamber 3b, so that the gas exchange device 4 can save the processing steps of the smelting chamber 2a, saving time, thereby improving the smelting efficiency.

[0055] It should be noted that, in the present application, multiple times refers to times including twice or more.

[0056] The specific type of the shielding gas is not limited, for example, the shielding gas may be argon or helium.

[0057] The anode mud processing equipment 100 provided in the embodiment of the present application, on the one hand, the crucible 1 containing the anode mud can leave the feed chamber 3b through the feed port 3a, so that it is easy to replace the crucible 1 and reduce the serious corrosion caused by repeated use of the same crucible 1. On the other hand, the path between the feed chamber 3b and the smelting chamber 2a is cut off by the gate valve 31, so that the smelting chamber 2a and the feed chamber 3b can each become a closed chamber, which can not only prevent the anode mud from reacting with oxygen to generate impurities, but also reduce the heat generated by the heating device 10 from diffusing outward, and achieve a better heat insulation effect. In addition, the operator does not need to put the crucible 1 directly into the smelting chamber 2a or directly take the crucible 1 out of the smelting chamber 2a, so as to prevent accidental contact with other devices in the smelting chamber 2a and cause damage, and can also reduce the risk of high-temperature gas scalding the operator. On the other hand, when multiple smelting of anode mud is required, the gas exchange device 4 only needs to evacuate the feed chamber 3b and replenish the protective gas. In this way, the gas exchange device 4 can omit the processing step of the smelting chamber 2a, saving time and thus improving the smelting efficiency.

[0058] In one embodiment, the crucible 1 can be a cold crucible, which is formed with a containing cavity for containing anode mud. The cold crucible has a cooling passage for circulating a cooling medium. During operation, the cooling medium flows in the cooling passage to cool the cavity wall of the containing cavity. The temperature of the anode mud is much higher than the temperature of the cavity wall. In this way, a solid shell is formed at the contact portion between the anode mud and the cavity wall. The shell can reduce the corrosion effect of the anode mud on the cold crucible, extend the service life of the cold crucible, and make the cold crucible reusable and convenient for processing corrosive materials.

[0059] The cooling medium refers to a medium that exchanges heat with an object and absorbs the heat of the object to cool the object. The cooling medium may be a fluid, for example, water or cooling oil.

[0060] In some embodiments, the anode mud treatment equipment 100 includes a vent valve, and the feeding device 3 and the furnace 2 are both provided with a vent valve, which can be used to connect the feeding chamber 3b and the smelting chamber 2a to the external environment, so that the environment of both the feeding chamber 3b and the smelting chamber 2a is roughly the same as the external environment.

[0061] In one embodiment, after the anode mud is heated and located in the feed chamber 3b, the gate valve 31 cuts off the path between the feed chamber 3b and the smelting chamber 2a, and the vent valve of the feed device 3 is opened first to make the air pressure in the feed chamber 3b equal to the external atmospheric pressure. In this way, the risk caused by a large air pressure difference between the feed chamber 3b and the external atmosphere can be avoided, and the process of opening the feed port 3a is also relatively labor-saving.

[0062] For some examples, see Figure 2 and Figure 3The feeding device 3 includes a valve driving member 32, and the valve driving member 32 drives the gate valve 31 to move so as to open or cut off the path between the feeding chamber 3b and the smelting chamber 2a. That is, the valve driving member 32 is connected to the gate valve 31 in a transmission manner, so that the driving force of the valve driving member 32 is transmitted to the gate valve 31, so that the gate valve 31 can spontaneously open or cut off the path between the feeding chamber 3b and the smelting chamber 2a, so that the degree of automation and production efficiency can be improved.

[0063] The valve driver 32 is a structure that can provide power. For example, the valve driver 32 can be a power source such as a motor or a cylinder.

[0064] In one embodiment, please refer to Figure 2 and Figure 3 The valve driving member 32 drives the gate valve 31 to move back and forth in the up and down directions to open or cut off the path between the feed chamber 3b and the smelting chamber 2a. In this way, the movement process of the gate valve 31 is relatively smooth and has good stability.

[0065] For some examples, see Figures 2 to 4 , the volume of the feed chamber 3b is smaller than the volume of the smelting chamber 2a. In this way, the time for the gas exchange device 4 to evacuate the feed chamber 3b and replenish the protective gas can be reduced, saving more time, improving the smelting efficiency, and reducing the protective gas consumed in each smelting process, thereby reducing production costs.

[0066] For some examples, see Figure 2 and Figure 3 The anode mud treatment equipment 100 includes a first driving mechanism 5, which is used to drive the crucible 1 to reciprocate between the feed chamber 3b and the smelting chamber 2a. In this way, there is no need for operators to manually control the crucible 1 to reciprocate between the feed chamber 3b and the smelting chamber 2a, which can not only avoid damaging the inert environment and protect the operators, but also improve the degree of automation and production efficiency.

[0067] For some examples, see Figure 2 and Figure 3 The feeding device 3 is arranged at one side of the furnace 2 along the first direction, and the first driving mechanism 5 is used to drive the crucible 1 to move along the first direction, so that the crucible 1 reciprocates between the feeding chamber 3b and the smelting chamber 2a, and the first direction is parallel to the horizontal plane. That is to say, in the process of the crucible 1 entering the smelting chamber 2a from the feeding chamber 3b or from the smelting chamber 2a into the feeding chamber 3b, the crucible 1 moves roughly along the horizontal direction, so that the movement process of the crucible 1 is relatively stable, thereby improving the operation reliability.

[0068] It should be noted that in the present application, the first direction may be the front-to-back direction, or the left-to-right direction. The front refers to the direction toward the operator during the use of the anode mud treatment equipment 100, and the back is the opposite direction to the front; the left refers to the side where the left hand of the operator is located when the operator is in front of the anode mud treatment equipment 100, the right is the opposite direction to the left, the bottom refers to the direction toward the ground, and the top is the opposite direction to the bottom; the front-to-back direction, the left-to-right direction, and the top-to-bottom direction are perpendicular to each other, and together constitute a three-dimensional vertical coordinate system.

[0069] For some examples, see Figure 2 and Figure 3 The first driving mechanism 5 includes a first driving member 51 and a clamping member 52. The first driving member 51 is connected to the clamping member 52 in a transmission manner. The clamping member 52 is used to clamp or release the crucible 1. The first driving member 51 is located outside the feed chamber 3b, and the clamping member 52 is located inside the feed chamber 3b. The clamping member 52 limits the crucible 1 and maintains the stability of the crucible 1. The first driving member 51 is located outside the feed chamber 3b to prevent the high-temperature gas in the smelting chamber 2a from entering the feed chamber 3b when the gate valve 31 is opened, causing damage to the first driving member 51.

[0070] See also Figure 2 The driving force of the first driving member 51 is transmitted to the clamping member 52, so that the clamping member 52 can drive the crucible 1 from the feeding chamber 3b into the smelting chamber 2a or drive the crucible 1 from the smelting chamber 2a into the feeding chamber 3b, thereby improving the degree of automation and production efficiency.

[0071] The first driving member 51 is a structure that can provide power. For example, the first driving member 51 can be a power source such as a motor or a cylinder.

[0072] For some examples, see Figure 2 and Figure 3 The anode mud processing equipment 100 includes a second driving mechanism 6, which is used to drive the crucible 1 to reciprocate in the up and down directions in the smelting chamber 2a to enter or escape from the heating device 10.

[0073] For example, see Figure 2 and Figure 3 The second driving mechanism 6 is located below the heating device 10. The heating device 10 is formed with a heating chamber that opens upward. The crucible 1 enters or escapes from the heating device 10 through the upward opening of the heating chamber. When the first driving mechanism 5 transfers the crucible 1 from the feeding chamber 3b to the smelting chamber 2a, the second driving mechanism 6 is connected to the crucible 1 in a transmission manner. The second driving mechanism 6 drives the crucible 1 to move downward into the heating chamber. The heating device 10 heats the crucible 1 to convert the anode mud into a molten state. After the heating is completed, the second driving mechanism 6 drives the crucible 1 to move upward and escape from the heating chamber.

[0074] In addition, when the crucible 1 enters and exits the heating device 10 , the crucible 1 moves approximately in the up and down direction, and the movement process of the crucible 1 is relatively stable, thereby improving the reliability of the operation.

[0075] For some examples, see Figure 2 and Figure 5 The second driving mechanism 6 includes a second driving member 61 and a placing table 62. The second driving member 61 is connected to the placing table 62 by transmission. The crucible 1 is placed on the placing table 62. The second driving member 61 is located outside the smelting chamber 2a, and the placing table 62 is located inside the smelting chamber 2a. The placing table 62 is used to support the crucible 1 and maintain the stability of the crucible 1. The second driving member 61 is located outside the smelting chamber 2a to prevent the high temperature in the smelting chamber 2a from damaging the second driving member 61.

[0076] See also Figure 2 and Figure 5 The driving force of the second driving member 61 is transmitted to the placement table 62, so that the placement table 62 can drive the crucible 1 to enter or escape from the heating device 10, thereby improving the degree of automation and production efficiency.

[0077] The second driving member 61 is a structure that can provide power. For example, the second driving member 61 can be a power source such as a motor or a cylinder.

[0078] For some examples, see Figure 6 and Figure 7 The anode mud processing equipment 100 includes a desalting device 7, which has a desalting position and an avoidance position. The desalting position is located above the heating device 10, and the avoidance position is located on one side of the desalting position in the horizontal direction. The desalting device 7 can reciprocate between the desalting position and the avoidance position; when the desalting device 7 is located at the desalting position, the desalting device 7 is used to collect salt evaporated from the anode mud during the heating process.

[0079] Salt refers to a type of metal ion or ammonium ion (NH4 + ) Compounds combined with acid radical ions, such as calcium sulfate, copper chloride, sodium acetate, etc. The evaporation of salt refers to the phase change process in which the salt contained in the anode mud is converted from the solid phase to the gas phase during the heating of the anode mud by the heating device 10. The gas phase salt condenses into a solid phase on the desalination device 7 to achieve salt collection. In this way, the gas phase salt is collected by the desalination device 7 to avoid the salt being adsorbed on the device, resulting in metal corrosion of each device, which affects the service life of the anode mud treatment equipment 100.

[0080] The desalting position refers to the position where the desalting device 7 is used to collect gaseous salts. At this time, with the plane perpendicular to the up and down directions as the projection plane, the projections of the desalting device 7, the crucible 1 and the heating device 10 at least partially overlap, and the desalting device 7 is roughly located above the heating device 10, so that the desalting device 7 can collect as much salt evaporated from the anode mud as possible.

[0081] The avoidance position refers to the position where the desalination device 7 and the heating device 10 are staggered. At this time, with the plane perpendicular to the up and down directions as the projection plane, the projections of the desalination device 7 and the heating device 10 are spaced apart, and the desalination device 7 is not above the heating device 10. In this way, the desalination device 7 will not block the crucible 1, so that the crucible 1 can smoothly enter and exit the heating device 10.

[0082] In one embodiment, the desalting device 7 and the furnace 2 are rotatably connected. Specifically, the rotation axis of the desalting device 7 extends in the up and down directions. In this way, it is not only convenient for the desalting device 7 to switch between the desalting position and the avoidance position, but the rotation range of the desalting device 7 is limited within a certain space, thereby saving the installation space required for the desalting device 7.

[0083] In some embodiments, the desalination device 7 may also be driven by a linear motor or a cylinder to perform linear reciprocating motion so as to switch between the desalination position and the avoidance position.

[0084] For some examples, see Figure 6 and Figure 7 The desalination device 7 includes a collecting member 71 and a flow guide member 72. The collecting member 71 forms a collecting chamber 71a. At least part of the flow guide member 72 extends into the collecting chamber 71a. The flow guide member 72 forms a flow guide channel 72a and an air inlet 72b open downward. The flow guide channel 72a connects the collecting chamber 71a and the air inlet 72b. The collecting member 71 can be used to cool gas phase salt. The cooling of salt refers to the phase change process of salt from gas phase to solid phase.

[0085] For example, see Figure 7 The gaseous salt moves upward, enters the guide channel 72a through the air inlet 72b, and enters the collecting chamber 71a under the guidance of the guide channel 72a. The collecting chamber 71a is used to collect the cooled salt, that is, to collect the solid-phase salt.

[0086] Please continue reading Figure 7 At least part of the guide member 72 extends into the collecting chamber 71a. In this way, at least part of the guide member 72 extending into the collecting chamber 71a can prevent the solid phase salt from seeping out of the collecting chamber 71a.

[0087] In one embodiment, please refer to Figure 7The air inlet 72b is formed at the lower end of the guide member 72, and the crucible 1 is formed with an inlet and outlet open upward. The projection surface is a plane perpendicular to the up and down directions, and the projection of the inlet and outlet is located within the projection range of the air inlet 72b. In this way, the air inlet 72b is closer to the inlet and outlet of the crucible 1, and the area of ​​the air inlet 72b is larger than the area of ​​the inlet and outlet, so that the desalination device 7 can better collect gaseous salt and improve the collection effect.

[0088] In one embodiment, the crucible 1 extends into the guide channel 72a through the air inlet 72b, and the upper end of the crucible 1 abuts against the wall of the guide channel 72a. In this way, the gap between the crucible 1 and the guide member 72 can be reduced, and the sealing between the crucible 1 and the guide member 72 is better, which prevents the gas phase salt from diffusing outward and further improves the collection effect.

[0089] For some examples, see Figure 7 The upper end of the guide member 72 is open to form an outlet 72c, which connects the collecting chamber 71a and the guide channel 72a. The projection of the outlet 72c is located within the projection range of the inlet 72b, taking the plane perpendicular to the up and down direction as the projection plane. After the gaseous salt enters the guide channel 72a, it enters the collecting chamber 71a through the outlet 72c. The outlet 72c is formed at the upper end of the guide member 72, thus shortening the flow path and reducing the flow resistance of the gaseous salt.

[0090] Please continue reading Figure 7 The peripheral side wall of the guide member 72 gradually tilts toward the middle from bottom to top, that is, the area of ​​the air inlet 72b is larger than the area of ​​the air outlet 72c, and the guide member 72 is trumpet-shaped, so that not only the gas phase salt has a small resistance to enter the guide channel 72a through the air inlet 72b, but also the gas phase salt can be effectively collected from the air inlet 72b with a larger opening area, under the guidance of the guide channel 72a, to the air inlet 72b with a smaller opening area, and then enter the collection chamber 71a, thereby improving the collection effect.

[0091] For some examples, see Figure 6 and Figure 7 The collecting member 71 is formed with an air suction port 71 b, which is communicated with the collecting chamber 71 a so that the air pressure in the collecting chamber 71 a is lower than the air pressure in the guide channel 72 a.

[0092] Exemplarily, the anode mud treatment equipment 100 includes an exhaust device, which is arranged outside the furnace 2, and the exhaust port 71b is connected to the exhaust device, and the gas in the collection chamber 71a is sucked by the exhaust device, so that the gas pressure in the collection chamber 71a is lower than the gas pressure in the guide channel 72a. In this way, the gas phase salt can spontaneously move to the collection chamber 71a through the guide channel 72a, thereby increasing the speed of the desalination device 7 to collect the gas phase salt and reducing the probability of the gas phase salt moving to other devices and causing an impact.

[0093] The specific type of the air extraction device is not limited, for example, the air extraction device can be a fan or the like.

[0094] It should be noted that, when the gas in the collecting chamber 71a is discharged to the outside through the exhaust port 71b, the ventilation device 4 evacuates the smelting chamber 2a and replenishes the protective gas to prevent the protective gas in the smelting chamber 2a from being discharged to the outside through the exhaust port 71b, affecting the gas pressure and inert environment of the smelting chamber 2a, so that the anode mud treatment equipment 100 maintains better stability during operation.

[0095] For some examples, see Figure 7 The collecting member 71 is formed with a cooling channel 71c, a liquid inlet 71d and a liquid outlet 71e, both of which are connected to the cooling channel 71c, and the cooling channel 71c is arranged around the outer periphery of the collecting chamber 71a. The cooling channel 71c is used to circulate the cooling medium.

[0096] Exemplarily, the cooling medium enters the cooling channel 71c through the liquid inlet 71d, exchanges heat with the gas phase salt while flowing in the cooling channel 71c, absorbs heat in the gas phase salt, and flows out through the liquid outlet 71e. The specific type of the cooling medium is not limited, for example, the cooling medium can be water or cooling oil.

[0097] For example, see Figure 7 The cooling channel 71c is arranged around the outer periphery of the collecting chamber 71a, that is, the cooling channel 71c surrounds the circumferential surface of the collecting chamber 71a, so that the cooling medium can fully exchange heat with the gas phase salt in the collecting chamber 71a, so that the gas phase salt is converted into a solid phase after cooling, thereby improving the heat exchange efficiency.

[0098] For some examples, see Figure 6 and Figure 7 The desalination device 7 includes a partition plate, which is arranged in the cooling channel 71c and partitions the cooling channel 71c, and the liquid inlet 71d and the liquid outlet 71e are respectively located on both sides of the partition plate. In other words, the cooling channel 71c is isolated at both ends, and the cooling channel 71c is an open ring structure.

[0099] See also Figure 6The liquid inlet 71d and the liquid outlet 71e are connected to the head and tail ends of the cooling channel 71c respectively, so that the cooling medium can enter from the liquid inlet 71d at the head end of the cooling channel 71c, flow through the entire cooling channel 71c along the circumferential direction, and then flow out from the liquid outlet 71e at the tail end of the cooling channel 71c to take away the heat. In this way, the flow path of the cooling medium in the cooling channel 71c can be extended, and the flow time of the cooling medium in the cooling channel 71c can be increased, so that the cooling medium can more fully absorb and take away the heat, thereby improving the heat exchange efficiency.

[0100] In some embodiments, the heating device 10 includes an induction coil, which is used to heat the anode mud. Specifically, the heating device 10 also includes a power supply, which is electrically connected to the induction coil to provide an alternating current. The induction coil generates an induced magnetic field under the action of electromagnetic induction to heat the anode mud.

[0101] Exemplarily, the induction coil is a multi-turn spiral coil structure, and the induction coil is surrounded to form a heating chamber. When an alternating current is passed through the induction coil, an induced magnetic field is generated, and when the crucible 1 is located in the induced magnetic field, an induced current, i.e., an eddy current, is generated. The eddy current generates heat energy during the flow in the crucible 1, thereby heating the anode mud.

[0102] The induction coil generates an induction magnetic field to heat the anode mud, which has the characteristics of fast heating speed, high efficiency, uniform temperature, etc. In addition, according to the different types and shapes of the crucible 1, an induction coil adapted thereto can be provided to achieve accurate heating of the anode mud.

[0103] In one embodiment, the heating device 10 includes a heat preservation structure, which is arranged around the circumferential surface of the heating chamber, and at least part of the induction coil is embedded in the heat preservation structure. In this way, on the one hand, the heat preservation structure plays a heat preservation role, which can reduce the heat energy generated by the induction coil from the inside of the heating chamber to the outside, thereby improving the heating effect. On the other hand, the induction coil is embedded in the heat preservation structure, which can enhance the connection stability between the heat preservation structure and the induction coil and prevent the induction coil from being deformed.

[0104] For some examples, see Figures 1 to 4 The anode mud treatment equipment 100 includes a heat preservation device 8, which is arranged in the smelting chamber 2a and above the heating device 10. The heat preservation device 8 forms a heat preservation chamber with a downward opening, and the crucible 1 can enter and exit the heat preservation chamber from the downward opening of the heat preservation chamber. For details, please continue to refer to Figure 2 The heat preservation device 8 is higher than the desalting device 7. When the anode mud in the crucible 1 is heated to a molten state, the salt in the anode mud is basically evaporated, and the desalting device 7 is switched from the desalting position to the avoidance position. The second driving mechanism 6 drives the crucible 1 to move upward and enter the heat preservation chamber through the downward opening of the heat preservation chamber.

[0105] In this embodiment, the heat preservation device 8 is used to slow down the cooling rate of the anode mud until the anode mud is cooled to the ambient temperature, and the ambient temperature can be the same as the room temperature. At this time, the anode mud solidifies into a metal ingot. Exemplarily, the heat preservation device 8 maintains the cooling rate of the anode mud at 10°C / min (degrees Celsius / minute). The heat preservation device 8 slows down the cooling rate of the anode mud. On the one hand, the distribution of radioactive nuclides can be optimized during the fixation process of the anode mud, so that the outer shell of the metal ingot can fully wrap the nuclides, reduce the radiation generated by the metal ingot, and improve safety. On the other hand, it can reduce or even eliminate the residual stress of the metal ingot, prevent the metal ingot from deformation, cracking, etc., improve the structural stability of the metal ingot, further reduce the probability of radiation radiating outward, and play a better protective role.

[0106] For some examples, see Figure 1 and Figure 2 The anode mud processing equipment 100 includes a temperature measuring device 9, which includes a first temperature measuring component 91 and a second temperature measuring component 92. The first temperature measuring component 91 is arranged on the side wall of the furnace 2 and is located outside the smelting chamber 2a, and the second temperature measuring component 92 is arranged below the heating device 10 and is located inside the smelting chamber 2a. The first temperature measuring component 91 and the second temperature measuring component 92 are both used to measure the temperature of the anode mud. In this way, on the one hand, when the heating device 10 heats the anode mud, that is, the crucible 1 is in the heating device 10, the second temperature measuring component 92 is closer to the crucible 1 than the first temperature measuring component 91; when the heat preservation device 8 is heat preservation for the anode mud, the first temperature measuring component 91 is closer to the crucible 1 than the second temperature measuring component 92. The first temperature measuring component 91 and the second temperature measuring component 92 can improve the accuracy of temperature measurement. On the other hand, the first temperature measuring component 91 is located outside the smelting chamber 2a, which can not only reduce the impact on the temperature field state in the smelting chamber 2a and improve the accuracy of temperature measurement, but also prevent the heat generated by the heating device 10 from damaging the first temperature measuring component 91.

[0107] The specific type of the first temperature measuring element 91 is not limited. For example, the first temperature measuring element 91 may be an infrared thermometer with high accuracy.

[0108] The specific type of the second temperature measuring component 92 is not limited. For example, the second temperature measuring component 92 may be a thermocouple, which can be used in a high temperature environment.

[0109] It should be understood that the upper side of the crucible 1 is open, that is, the upper side of the anode mud in the crucible 1 is exposed. In this way, during the heating and melting process of the anode mud, an oxide film will be formed on the upper surface of the anode mud, and the anode mud below the oxide film will be preferentially converted into a molten state. The second temperature measuring component 92 is arranged below the heating device 10, and can detect the temperature of the molten anode mud, thereby reflecting the temperature of the anode mud in real time. Further, after the oxide film is completely melted, the entire anode mud is in a molten state, and the oxide film will not block the first temperature measuring component 91 from measuring the temperature. In this way, the temperatures measured by the first temperature measuring component 91 and the second temperature measuring component 92 are coupled, which can more accurately reflect the real-time temperature of the anode mud and improve the accuracy of temperature measurement.

[0110] In one embodiment, please refer to Figure 2 The first temperature measuring component 91 is connected to the upper side wall of the furnace 2, so that it is convenient to load, unload and replace the first temperature measuring component 91.

[0111] For some examples, see Figure 3 , Figure 4 and Figure 6 The desalination device 7 is formed with a first visible window 7a, and the heat preservation device 8 is formed with a second visible window 8a. When the heating device 10 heats the anode mud, with the plane perpendicular to the up and down directions as the projection plane, the projections of the first temperature measuring component 91, the first visible window 7a and the second visible window 8a at least partially overlap.

[0112] Exemplarily, with the plane perpendicular to the up-down direction as the projection plane, the projection of the crucible 1 is located within the overlapping range of the projections of the first temperature measuring element 91, the first visible window 7a and the second visible window 8a. In this way, it is possible to avoid the insulation device 8 and the desalination device 7 blocking the first temperature measuring element 91, and the first temperature measuring element 91 can measure the temperature of the anode mud through the first visible window 7a and the second visible window 8a, thereby realizing the temperature measurement of the anode mud by the first temperature measuring element 91 during the whole process from heating to insulation.

[0113] For example, when the heating device 10 heats the anode mud, the projections of the first temperature measuring element 91, the first visible window 7a and the second visible window 8a are at least partially overlapped with each other, taking the plane perpendicular to the up-down direction as the projection plane. For another example, when the heat preservation device 8 is heat-insulating the anode mud, the projections of the first temperature measuring element 91 and the first visible window 7a are at least partially overlapped with each other, so that the accuracy of temperature measurement can be improved, the control of the operator is convenient, and the operation reliability of the anode mud processing equipment 100 is improved.

[0114] The first visible window 7a and the second visible window 8a may be made of transparent materials, for example, they may be glass windows and the like.

[0115] In one embodiment, please refer to Figure 3 and Figure 4 The second visual window 8a passes through the upper side wall of the stove 2. In this way, there is no need to additionally set a transparent visual structure on the stove 2, thereby reducing the manufacturing steps and the production cost.
