Description

Technical Field

[0001] The invention belongs to the technical field of metal refining, and in particular relates to an anti-oxidation refining tank for continuous feeding production of aluminum ingots. Background Art

[0002] Metal refining is the process of converting raw metals containing impurities into high-purity metals through a series of physical, chemical, or electrochemical processes. These processes are designed to remove non-metallic inclusions, low-melting-point metals, gases, and other harmful elements from the metal, thereby improving the purity, performance, and value of the metal. Metal refining requires the use of metal refining tanks.

[0003] Chinese patent (CN117845064A) discloses a metal refining device comprising: a primary purification device having a first crucible with three temperature zones arranged externally thereon: an upper heating zone, a lower heating zone, and a bottom heating zone; a secondary purification device having a second crucible, which is held by a clamp connected to a separation block. The clamp controls the opening and closing of a copper clamp (the copper clamp is the clamp for the upper and lower lugs of the crucible) through the separation block to clamp and release the crucible. The copper clamp can conduct current when the crucible is clamped. After metal refining is completed, the clamp is released to facilitate removal of the crucible. An inverter power supply is connected to a step-down transformer, and the output current of the step-down transformer is conducted to the second crucible via a copper plate. The device uses online infrared temperature measurement, featuring a compact probe, easy installation, strong anti-interference capability, good linearity, and a large distance coefficient ratio. This allows measurement in confined locations, improving temperature measurement accuracy. Although today's metal refining equipment can also achieve the refining treatment of metals, there are still some problems in actual application. The main problem is that when the metal is refined, the molten metal liquid will remain on the inner surface. Generally, traditional equipment uses a separate scraper to process and remove the metal liquid. Although it has a certain effect, the temperature inside the tank is not consistent, and the temperature on the upper part is often lower than the core temperature of the tank. Therefore, the residual metal liquid on the upper part of the tank will solidify to a certain extent. The scraper cannot solve the problem, resulting in a large amount of raw material waste when the equipment is used. The actual application effect is not good. There is an urgent need for an anti-oxidation refining tank for continuous production of aluminum ingots. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that although the current metal refining equipment can also realize the refining treatment of metal, there are still some problems in actual application. The main problem is that when the metal is refined, the molten metal liquid will remain on the inner surface. Generally, traditional equipment uses a separate scraper to realize the treatment and removal of the metal liquid. Although it has a certain effect, since the temperature inside the tank is not consistent, the temperature of the upper part is often lower than the core temperature of the tank body. Therefore, the residual metal liquid on the upper part of the tank body will solidify to a certain extent. The scraper cannot solve the problem, resulting in a large amount of raw material waste when the equipment is used, and the actual application effect is not good. An anti-oxidation refining tank for continuous production of aluminum ingots is proposed.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, by arranging the turning assembly and the inner wall cleaning mechanism inside, when the equipment is actually used, the aluminum ingots to be processed are continuously put into the refining tank, the temperature inside the refining tank is increased, the driving motor is turned on, and the turning shaft and the turning blade are controlled to rotate to realize the turning of the aluminum ingot. At this time, the temperature inside the refining tank is increased to melt the aluminum ingot. During this process, the raw materials are continuously turned over. When the turning shaft rotates, the meshing gear ring can be driven to rotate, thereby synchronously driving the inner gear ring to rotate. At this time, the several surrounding cleaning assemblies at the bottom of the inner gear ring can make a circular motion on the inner surface of the refining tank. At this time, the walking roller will rotate, driving the surrounding cleaning plate to rotate synchronously. At this time, the rotating turning blade and the surrounding cleaning plate can synchronously realize the removal of the residual residue on the inner surface of the refining tank. The material is scraped off, and at the same time, as the surrounding cleaning plate rotates, the built-in rotating plate can be deflected under the action of centrifugal force, and the knocking ball can be driven to knock the inner wall of the refining tank. As the speed of the driving motor changes, the knocking frequency of the knocking ball will also change. The knocking ball can process some solidified wall residues and effectively eliminate them. Through this design, not only can the real-time turning of the material during the refining process of aluminum ingots be realized, and the refining efficiency can be improved, but also the treatment of the residue can be realized in various forms, which can effectively solve the problem that due to the inconsistent temperature in the tank body, the temperature of the upper part is often lower than the core temperature of the tank body, and the residual metal liquid on the upper part of the tank body is solidified to a certain extent, which is difficult to handle, thereby greatly improving the actual application effect of the overall equipment.

[0028] 2. In the present invention, the inner wall cleaning mechanism and the turning assembly are designed to be split and quick-installed. When the equipment needs to be cleaned internally, the inner wall cleaning mechanism can be directly extracted using a hook. At this time, the extracted inner wall cleaning mechanism can be quickly cleaned and replaced. At the same time, after the inner wall cleaning mechanism is removed, the space inside the refining tank can be expanded, which is convenient for further cleaning of the refining tank. When reassembling, the inner wall cleaning mechanism can be directly placed on the installation step, and the inner gear ring and the meshing gear ring can automatically mesh and work normally. The operation is simple and quick, thereby improving the actual application effect of the equipment.

[0029] 3. In the present invention, a discharge assembly is provided. After the aluminum ingot is heated to a molten state, some reactants are added, and the nitrogen box is opened to introduce nitrogen into the equipment to prevent the molten liquid from oxidizing. After the treatment is completed, the discharge is carried out. When the turning shaft rotates, the driving bevel gear can drive the rotation of the driving bevel gear, and the driving bevel gear can drive the installation shaft with the driven bevel gear to rotate. At this time, the two reciprocating screws can rotate synchronously, driving the discharge push block installed outside it to reciprocate in the discharge port. At this time, the upper pure metal liquid can be further filtered through the filter hole and then discharged. After the discharge is completed, the impurity discharge pipe is opened to discharge the impurities deposited at the bottom of the metal liquid to complete the refining operation. Through this design, the driving force for turning the aluminum ingot can be used to realize the reciprocating discharge and push of the metal liquid, and the metal liquid can be filtered while discharging, which can further improve the working efficiency and use effect of the refining tank.

Discharge ports 6 are fixedly mounted on the outer walls of both sides of the refining tank 5. A discharge assembly 13 is provided inside the discharge port 6. The discharge assembly 13 is used for discharging the refined raw materials.

[0043] The turning assembly 12 includes a mounting spindle 122, which is fixedly mounted on the bottom end of the output shaft of the driving motor 1. A hollow mounting frame 121 is fixedly mounted on the outside of the mounting spindle 122, and an engaging gear ring 123 is fixedly mounted on the outside of the hollow mounting frame 121. A turning shaft 124 is fixedly mounted on the bottom end of the mounting spindle 122, and a turning blade 125 is fixedly mounted on the outside of the turning shaft 124. A driving bevel gear 126 is fixedly mounted on the bottom end of the turning shaft 124, and one end of the turning blade 125 is in close contact with the inner surface of the refining tank 5.

[0044] The inner wall cleaning mechanism 11 includes an inner gear ring 111 , which is rotatably mounted on the mounting step 14 , and the inner gear ring 111 is meshed with the meshing gear ring 123 .

[0045] A plurality of surrounding cleaning assemblies 112 are provided on the bottom surface of the inner gear ring 111, and the surrounding cleaning assembly 112 includes a bottom shaft 1126, which is rotatably mounted on the bottom surface of the inner gear ring 111, and a walking roller 1121 and a surrounding cleaning plate 1122 are fixedly mounted on the outside of the bottom shaft 1126, and the walking roller 1121 is located above the surrounding cleaning plate 1122, and the walking roller 1121 is rollingly connected to the inner surface of the refining tank 5, and a mounting side groove 1124 is provided on the outer wall of one side of the surrounding cleaning plate 1122, and a built-in rotating plate 1123 is rotatably mounted on the inner side of the mounting side groove 1124 through a rotating shaft, and a plurality of knocking balls 1125 are fixedly mounted on one end of the built-in rotating plate 1123 through a connecting rod, and four surrounding cleaning plates 1122 and the built-in rotating plates 1123 are arranged in a circle.

[0046] The specific implementation method is as follows: when the equipment is actually used, the aluminum ingots to be processed are continuously put into the refining tank 5, the temperature in the refining tank 5 is increased, the driving motor 1 is turned on, and the turning shaft 124 and the turning blade 125 are controlled to rotate to realize the turning of the aluminum ingot. At this time, the temperature in the refining tank 5 is increased to melt the aluminum ingot. During this process, the raw materials are continuously turned over. When the turning shaft 124 rotates, the meshing gear ring 123 can be driven to rotate, thereby synchronously driving the inner gear ring 111 to rotate. At this time, the several surrounding cleaning components 112 at the bottom of the inner gear ring 111 can make a circular motion on the inner surface of the refining tank 5. At this time, the walking roller 1121 will rotate, driving the surrounding cleaning plate 1122 to rotate synchronously. At this time, the rotating material turning blade 125 and the surrounding cleaning plate 1122 can synchronously scrape off the residual material remaining on the inner surface of the refining tank 5. At the same time, as the surrounding cleaning plate 1122 rotates, the built-in rotating plate 1123 can be deflected under the action of centrifugal force, and at this time, the knocking ball 1125 can be driven to knock on the inner wall of the refining tank 5. As the speed of the driving motor 1 changes, the knocking frequency of the knocking ball 1125 will also change. The knocking ball 1125 can process some solidified wall-hanging residual materials and effectively eliminate them.

[0047] Through this design, not only can the real-time turning of the aluminum ingots during the refining process be achieved to improve the refining efficiency, but also the residual materials can be processed in various forms. It can effectively solve the problem that due to the inconsistent temperature in the tank body, the temperature of the upper part is often lower than the core temperature of the tank body, and the residual metal liquid on the upper part of the tank body is solidified to a certain extent, which is difficult to handle, thereby greatly improving the actual application effect of the overall equipment.

[0048] Furthermore, by designing the inner wall cleaning mechanism 11 and the turning component 12 to be split and quick-installed, when the equipment needs to be cleaned internally, the inner wall cleaning mechanism 11 can be directly extracted using a hook. At this time, the extracted inner wall cleaning mechanism 11 can be quickly cleaned and replaced. At the same time, after the inner wall cleaning mechanism 11 is removed, the space inside the refining tank 5 can be expanded, which is convenient for further cleaning of the refining tank 5. When reassembling, the inner wall cleaning mechanism 11 can be directly placed on the installation step 14, and the inner gear ring 111 and the meshing gear ring 123 can automatically mesh and work normally. The operation is simple and quick, thereby improving the actual application effect of the equipment.

[0049] The discharge assembly 13 includes a mounting shaft 132, a mounting shaft frame is fixedly installed inside the refining tank 5, the mounting shaft 132 is rotatably installed on the mounting shaft frame, reciprocating screws 133 are fixedly installed at both ends of the mounting shaft 132, and a discharge push block 134 is threadedly installed on the outside of the reciprocating screw 133. The discharge push block 134 is slidably connected to the discharge port 6, and a plurality of filter holes 135 are provided inside the discharge push block 134. A driven bevel gear 131 is fixedly installed on the outside of the middle position of the mounting shaft 132, and the driving bevel gear 126 and the driven bevel gear 131 are meshed with each other.

[0050] The specific implementation method is as follows: after the aluminum ingot is heated to a molten state, some reactants are added, and the nitrogen box 4 is opened to introduce nitrogen into the equipment to prevent the molten liquid from being oxidized. After the treatment is completed, the material is discharged. When the turning shaft 124 rotates, the driving bevel gear 126 can be driven to rotate. The driving bevel gear 126 can drive the installation shaft 132 with the driven bevel gear 131 to rotate. At this time, the two reciprocating screws 133 can rotate synchronously, driving the discharge push block 134 installed outside it to reciprocate in the discharge port 6. At this time, the upper layer of pure metal liquid can be further filtered through the filter hole 135 and then discharged. After the discharge is completed, the impurity discharge pipe 10 is opened to discharge the impurities deposited at the bottom of the metal liquid to complete the refining operation.

[0051] Working principle: When the equipment is actually used, the aluminum ingots to be processed are continuously put into the refining tank 5, the temperature in the refining tank 5 is increased, the driving motor 1 is turned on, and the turning shaft 124 and the turning blade 125 are controlled to rotate to realize the turning of the aluminum ingots. At this time, the temperature in the refining tank 5 is increased to melt the aluminum ingots. During this process, the raw materials are continuously turned over. When the turning shaft 124 rotates, the meshing gear ring 123 can be driven to rotate, thereby synchronously driving the inner gear ring 111 to rotate. At this time, the several surrounding cleaning components 112 at the bottom of the inner gear ring 111 can make a circular motion on the inner surface of the refining tank 5. The walking roller 1121 rotates, driving the surrounding cleaning plate 1122 to rotate synchronously. At this time, the rotating material turning blade 125 and the surrounding cleaning plate 1122 can synchronously scrape off the residual materials remaining on the inner surface of the refining tank 5. At the same time, as the surrounding cleaning plate 1122 rotates, the built-in rotating plate 1123 can deflect under the action of centrifugal force, and at this time, it can drive the knocking ball 1125 to knock on the inner wall of the refining tank 5. As the speed of the driving motor 1 changes, the knocking frequency of the knocking ball 1125 will also change. The knocking ball 1125 can process some solidified wall-hanging residual materials and effectively eliminate them.

[0052] When the equipment needs to be cleaned internally, the inner wall cleaning mechanism 11 can be directly extracted using a hook. At this time, the extracted inner wall cleaning mechanism 11 can be quickly cleaned and replaced. At the same time, after the inner wall cleaning mechanism 11 is removed, the space inside the refining tank 5 can be expanded, which is convenient for further cleaning inside the refining tank 5. When reassembling, the inner wall cleaning mechanism 11 can be directly placed on the installation step 14. The inner gear ring 111 and the meshing gear ring 123 can automatically mesh and work normally. The operation is simple and fast.

[0053] After the aluminum ingot is heated to a molten state, some reactants are added, and the nitrogen box 4 is opened to introduce nitrogen into the equipment to prevent the molten liquid from being oxidized. After the treatment is completed, the material is discharged. When the turning shaft 124 rotates, the driving bevel gear 126 can be driven to rotate. The driving bevel gear 126 can drive the installation shaft 132 with the driven bevel gear 131 to rotate. At this time, the two reciprocating screws 133 can rotate synchronously, driving the discharge push block 134 installed outside it to reciprocate in the discharge port 6. At this time, the upper layer of pure metal liquid can be further filtered through the filter hole 135 and then discharged. After the discharge is completed, the impurity discharge pipe 10 is opened to discharge the impurities deposited at the bottom of the metal liquid to complete the refining operation.
