[0030] By arranging the stirring rod 121 in the reaction chamber 11 and connecting the stirring driving member 122 to the stirring rod 121, the stirring rod 121 can be driven by the stirring driving member 122 to rotate in the reaction chamber 11. By spirally arranging the heating tube 13 in the height direction of the reaction chamber 11, the metal ore in the reaction chamber 11 can be heated by the electric heating of the heating tube 13. By adding a reactant in the reaction chamber 11, a physical and chemical reaction of the metal ore can be achieved under the action of the heating tube 13 and the reactant, thereby extracting pure metal material from the metal ore.

[0031] Since the stirring rod 121 is driven to rotate by the stirring driving member 122 during the refining of the metal ore, the metal ore can be stirred under the stirring action of the stirring rod 121, thereby making the metal ore heated more evenly and making the contact between the reactant and the metal ore more even, thereby improving the reaction efficiency of the metal ore and improving the refining efficiency of the metal material.

[0032] See also Figure 3-Figure 4 In the embodiment of the utility model, the metallurgical reactor 1 further comprises a cooling assembly 14, the cooling assembly 14 comprises a water inlet pipe 141, a water outlet pipe 142, a cold water tank 143, a water pumping drive 144, a first connecting sleeve 123 and a second connecting sleeve 124, the upper end of the stirring rod 121 is provided with a first groove 1211, the lower end is provided with a second groove 1212, the stirring rod 121 is provided with a groove in the vertical direction of the first groove 1211 and connected with the second groove 1212 The guide hole 1213, the first connecting sleeve 123 is rotatably connected to the first groove 1211, the second groove 1212 is rotatably connected to the second groove 1212, one end of the water inlet pipe 141 is connected to the water pumping drive 144, and the other end is connected to the first connecting sleeve 123, one end of the water outlet pipe 142 is connected to the second connecting sleeve 124, and the other end extends into the cold water tank 143, and the water pumping drive 144 is installed in the cold water tank 143 to extract coolant to the water inlet pipe 141.

[0033] A first groove 1211 for rotationally connecting the first connecting sleeve 123 is provided at the upper end of the stirring rod 121, a second groove 1212 for rotationally connecting the second connecting sleeve 124 is provided at the lower end of the stirring rod 121, and a guide hole 1213 connecting the first groove 1211 and the second groove 1212 is provided on the stirring rod 121, so that the pumping drive 144 in the cold water tank 143 can extract the coolant, and the coolant passes through the water inlet pipe 141, the first groove 1211, the guide hole 1213, the second groove 1212 and the water outlet pipe 142 in sequence, and is discharged into the cold water tank 143 from the water outlet pipe 142, thereby forming a circulating cooling and temperature reduction effect on the stirring rod 121, thereby preventing the stirring rod 121 from affecting the service life of the stirring rod 121 due to excessive temperature when stirring the metal ore.

[0034] In the embodiment of the present utility model, a cooling fin 145 is disposed in the cold water tank 143 , and the cooling fin 145 is electrically connected to an external compressor to cool the coolant in the cold water tank 143 .

[0035] By setting the refrigeration plate 145 in the cold water tank 143 and electrically connecting the refrigeration plate 145 to an external compressor, the compressor compresses the air to obtain cold air and transfers it to the refrigeration plate 145, thereby achieving the effect of cooling the coolant in the cold water tank 143, so that the water pumping drive 144 can draw the cooled coolant into the stirring rod 121, thereby achieving the circulation cooling and cooling effect on the stirring rod 121.

[0036] In an embodiment of the utility model, the guide holes 1213 are arranged in an array along the circumferential direction of the stirring rod 121. By opening the guide holes 1213 in an array along the circumferential direction of the stirring rod 121, the coolant can enter the interior of the stirring rod 121 through each guide hole 1213 to achieve a water-cooling effect on the stirring rod 121. Since the guide holes 1213 are arranged in an array along the circumferential direction of the stirring rod 121, the coolant entering the stirring rod 121 can evenly cool the interior of the stirring rod 121, thereby increasing the service life of the stirring rod 121.

When the stirring driving member 122 drives the stirring rod 121 to rotate, the first connecting sleeve and the second connecting sleeve are respectively stationary relative to the stirring rod 121 under the sleeve connection of the first groove 1211 and the second groove 1212, and the water pumping driving member 144 draws the coolant in the cooling tank into the guide hole 1213 through the water inlet pipe 141. Since the stirring rod 121 is in a rotating state, the coolant passing through the water inlet pipe 141 can evenly enter the various guide holes 1213 in the circumferential direction of the stirring rod 121, thereby achieving uniform cooling of the stirring rod 121. After the coolant enters the guide hole 1213, it falls into the second connecting sleeve under the action of gravity, and flows back to the cooling tank through the outlet pipe 142. The heat generated by the stirring rod 121 when stirring the metal ore is brought to the cooling tank by the coolant, thereby realizing cyclic cooling of the stirring rod 121 and preventing the temperature of the stirring rod 121 from being too high and affecting the stirring effect and service life.

[0038] It can be understood that the second connecting sleeve is provided with a reflux hole connected to the guide hole 1213, so that the coolant in the guide hole 1213 flows into the second connecting sleeve through the reflux hole, and flows back to the cooling groove from the outlet pipe 142 connected to the second connecting sleeve. In the above embodiment, a sealing rubber pad is provided at the sleeve joint of the first connecting sleeve and the first groove 1211 to prevent the coolant from leaking out. Similarly, a sealing rubber pad is provided at the sleeve joint of the second connecting sleeve and the second groove 1212 to prevent the coolant from leaking out.

A flange 111 for connecting the connecting plate 161 is arranged on the top of the reaction chamber 11, and the exhaust pipe is connected to the reaction chamber 11 from the outside of the reaction chamber 11.

[0040] By arranging a flange 111 on the top of the reaction chamber 11, the connecting plate 161 is covered on the top of the reaction chamber 11 through the flange 111, so that the reaction chamber 11 can fully react with the metal ore and improve the refining purity and refining efficiency of the metal material.

[0042] By setting a feed port on the connecting plate 161, it is convenient for operators to add metal ore into the reaction chamber 11 through the feed port, and the metal ore is subjected to chemical reactions such as plate formation, reduction, chlorination, leaching, and decomposition under the reaction of the reaction chamber 11, so as to extract the metal material from the metal ore. By setting a discharge port 112 at the bottom of the reaction chamber 11, after the reaction of the metal ore in the reaction chamber 11 is completed, the metal material extracted in the reaction chamber 11 can be discharged from the discharge port 112 by opening the discharge port 112.

[0043] In an embodiment of the utility model, the feed hopper 162 is in an open shape that is wide at the top and narrow at the bottom, so that when the operator adds metal ore into the reaction chamber 11, the feed hopper 162 guides the metal ore to ensure that the added metal ore can accurately enter the interior of the reaction chamber 11, thereby preventing the metal ore from spilling outside the reaction chamber 11 and affecting the normal operation of the operator.

[0044] In an embodiment of the utility model, the stirring driving member 122 is installed on the connecting plate 161 and connected to the stirring rod 121, so that the stirring driving member 122 at the top drives the stirring rod 121 to rotate in the reaction chamber 11, thereby achieving the stirring effect on the metal ore, so as to improve the reaction efficiency of the metal ore and improve the refining efficiency of the metal material.

[0045] In other embodiments of the present invention, the stirring drive member 122 is installed at the bottom of the reaction chamber 11 and connected to the stirring rod 121, so that the stirring drive member 122 at the bottom drives the stirring rod 121 to rotate in the reaction chamber 11, thereby achieving a stirring effect on the metal ore, thereby improving the reaction efficiency of the metal ore and improving the refining efficiency of the metal material.

[0046] In an embodiment of the utility model, the pumping drive 144 includes any one of a centrifugal pump, a gear pump, and a screw pump, so that the coolant in the cooling tank is pumped into the stirring rod 121 under the action of the pumping drive 144, thereby realizing the cooling effect on the stirring rod 121.
