[0034] The cooling mechanism 11 includes a connecting pipe 1101, which is rotatably installed through the bottom of the mixing drum 2.

A first rotating shaft 1104 is rotatably installed through the mixing drum 2. The first rotating shaft 1104 is a hollow structure. A cooling pipe 1105 is fixedly inserted on the inner surface of the first rotating shaft 1104. The bottom end of the cooling pipe 1105 is rotatably connected to a second delivery pipe 1106. One end of the second delivery pipe 1106 away from the cooling pipe 1105 passes through the cooling chamber 3 and the mixing drum 2 and is connected to the first delivery pipe 1102.

By setting the cooling gas storage cylinder 1201, it is convenient to store the cooling gas.

The transmission connection of multiple rotating wheels and belts realizes power transmission from the servo motor 1302 to the connecting pipe 1101, the second rotating shaft 1307 and the first rotating shaft 1104. The transmission efficiency is high, which can ensure the coordinated rotation of the stirring structure and the cooling structure, and improve the overall working efficiency and reliability of the device.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, two fixed plates 1306 are fixedly connected to the outer surface of the mixing drum 2, and a second rotating shaft 1307 is rotatably installed on the two fixed plates 1306. Two second rotating wheels 1308 are arranged on the outer surface of the connecting tube 1101 and the bottom end of the second rotating shaft 1307, and the outer surfaces of the two second rotating wheels 1308 are transmission-connected with a second belt 1309.

[0040] like Figure 1 , Figure 4 and Figure 6 As shown, the air intake mechanism 14 includes a square tube 1401, which is fixedly connected to the top of the connecting tube 1101. An air collecting port 1402 is arranged on the top of the square tube 1401. A support plate 1403 is fixedly connected to the inner surface of the air collecting port 1402. A second rotating rod 1404 is connected to the support plate 1403 through a bearing. A fan blade 1405 is fixedly installed on the top of the second rotating rod 1404. By setting the fan blade 1405, it is convenient to evenly blow the cooling gas into the cooling chamber 3. The support plate 1403 is arranged to support the second rotating rod 1404, so as to facilitate the stable rotation of the second rotating rod 1404.

[0041] like Figure 5 and Figure 6 As shown, a third rotating shaft 1406 is rotatably connected in the square tube 1401, and two bevel gears 1407 are fixedly connected to the outer surface of the third rotating shaft 1406 and the bottom end of the second rotating rod 1404, and the two bevel gears 1407 are meshingly connected. A micro motor 1408 is fixedly installed on one side of the square tube 1401, and the output end of the micro motor 1408 movably passes through the square tube 1401 and is fixedly connected to the third rotating shaft 1406.

A porous plate 1410 is fixedly connected in the cooling chamber 3, and the rotational power of the micro motor 1408 is converted into the rotational power of the fan blades 1405 through the meshing transmission of the bevel gears 1407, so that the fan blades 1405 can evenly blow the cooling gas into the cooling chamber 3, and the porous plate 1410 can evenly distribute the cooling gas in the cooling chamber 3, increase the contact area between the cooling gas and the cooling chamber 3, and improve the heat exchange efficiency.

[0042] like Figure 1 and Figure 8 As shown, the stirring mechanism 15 includes a stirring rod 1501, which is fixedly connected to the outer surface of the first rotating shaft 1104, and two spiral stirring plates 1502 are fixedly connected to the outer surface of the first rotating shaft 1104. The spiral directions of the two spiral stirring plates 1502 are opposite. A cavity 1503 is opened at one end of the stirring rod 1501, and the cavity 1503 is connected to the cooling pipe 1105. The cavity 1503 is connected to the cooling pipe 1105, so that the cooling gas can directly act on the material around the stirring rod 1501, thereby achieving more precise local cooling of the material during the stirring process.

[0043] like Figure 4 , Figure 5 and Figure 6 As shown, a second support sleeve 1107 is fixedly connected to the top of the bottom plate 1, the first delivery pipe 1102 is fixedly connected to the inner surface of the second support sleeve 1107, a third support sleeve 1108 is fixedly connected in the cooling chamber 3, the second delivery pipe 1106 is fixedly connected to the inner surface of the third support sleeve 1108, and a discharge pipe 17 is fixedly connected to the outer surface of the mixing drum 2, and a second solenoid valve 18 is installed on the discharge pipe 17. The second support sleeve 1107 and the third support sleeve 1108 respectively fix and support the first delivery pipe 1102 and the second delivery pipe 1106 to ensure the stability of the pipeline during the operation of the device and prevent the gas delivery and cooling effects from being affected by pipeline shaking or displacement. The discharge pipe 17 facilitates the discharge of materials after leaching is completed, and the second solenoid valve 18 facilitates the control of the discharge.

[0044] The usage and working principle of the device: in the preparation stage, the two first solenoid valves 10 on the feed port 7 and the liquid inlet 8 are opened through the PLC controller 16, the material to be leached is put into the mixing drum 2, and the leachate is injected into the mixing drum 2 through the liquid inlet 8, and then the two first solenoid valves 10 on the feed port 7 and the liquid inlet 8 are closed through the PLC controller 16, and then the target temperature and pressure in the mixing drum 2 are set through the PLC controller 16 according to the leaching process requirements.

[0045] During the stirring stage, the servo motor 1302 is started through the PLC controller 16. The servo motor 1302 drives the first rotating rod 1303 to rotate. The connecting pipe 1101 is rotated through the transmission of the first rotating wheel 1304 and the first belt 1305. The rotation of the connecting pipe 1101 is driven by the second rotating wheel 1308 and the second belt 1309, and the third rotating wheel 1310 and the third belt 1311, respectively driving the second rotating shaft 1307 and the first rotating shaft 1104 to rotate. The first rotating shaft 1104 rotates the stirring rod 1501 and the spiral stirring plate 1502. The rotating stirring rod 1501 stirs the material so that the material and the leachate are fully contacted and mixed. The opposite spiral directions of the two spiral stirring plates 1502 can cause the material to flip up and down in the stirring drum 2.

[0046] In the environmental control stage, during the mixing process, the temperature sensor 5 and the pressure sensor 6 monitor the temperature and pressure inside the mixing drum 2 in real time. When the temperature sensor 5 detects that the temperature inside the mixing drum 2 is lower than the target temperature, the temperature sensor 5 sends a signal to the PLC controller 16. After receiving the signal, the PLC controller 16 controls the electric heating ring 4 to turn on the power for heating, so that the temperature inside the mixing drum 2 is heated to the target temperature. At the same time, when the pressure sensor 6 detects that the pressure inside the mixing drum 2 deviates from the target pressure, the pressure sensor 6 sends a signal to the PLC controller 16. After receiving the signal, the PLC controller 16 opens the first solenoid valve 10 on the feed port 7 to release the pressure. When the pressure inside the mixing drum 2 returns to the target pressure, the pressure sensor 6 detects that the pressure inside the mixing drum 2 returns to the target pressure. The pressure sensor 6 sends the detected signal to the PLC controller 16. After receiving the signal, the PLC controller 16 controls the closing of the first solenoid valve 10 on the feed port 7.

[0047] During the leaching process, as the reaction proceeds, heat is released. When the temperature sensor 5 detects that the temperature in the mixing drum 2 is higher than the target temperature, the temperature sensor 5 sends the detected signal to the PLC controller 16. After receiving the signal, the PLC controller 16 starts the air pump 1103, the cooling fan 1209 and the micro motor 1408. The air pump 1103 extracts the cooling gas in the cooling gas storage cylinder 1201 and draws it into the square tube 1401 through the first delivery pipe 1102 and the connecting pipe 1101. At the same time, the micro motor 1408 drives the third rotating shaft 1406 to rotate. The third rotating shaft 1406 drives the second rotating rod 1404 to rotate through the bevel gear 1407. The fan blades 1405 rotate to blow the cooling gas into the cooling chamber 3 through the gas collecting port 1402 to promote heat exchange. At the same time, during the stirring process, the connecting pipe 1101 drives the square tube 1401 to rotate synchronously, so that the cooling gas is evenly blown into the cooling chamber 3. At the same time, the cooling gas drawn out by the air pump 1103 enters the cooling pipe 1105 through the second delivery pipe 1106, so that the cooling gas exchanges heat with the heat in the mixing drum 2 when flowing in the cooling pipe 1105 and the cooling chamber 3, and evenly cools the material and the leachate in the mixing drum 2, so that the temperature in the mixing drum 2 drops to the target temperature, and the cooled gas returns to the cooling gas storage cylinder 1201 through the first outlet pipe 1205 and the second outlet pipe 1206. At the same time, the coolant in the cooling liquid storage cylinder 1203 can absorb the heat brought out by the first outlet pipe 1205, and dissipate the heat through the heat dissipation fins 1208 and the heat dissipation fan 1209.

[0048] In the discharging stage, the second solenoid valve 18 is opened by the PLC controller 16 to discharge the leached material and liquid mixture.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
