[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Example 1

[0028] refer to Figure 1-5 A precious metal alkali melting water immersion device comprises a furnace body 1, a first driving module 2, and a water immersion kettle 3. The furnace body 1 is provided with a pouring port 11, and further comprises a lifting unit 4. The lifting unit 4 is used to drive the water immersion kettle 3 to rise and fall between a height flush with the ground and a first height below the ground;

[0029] When the lifting unit 4 drives the water immersion kettle 3 to descend to the first height, the first driving module 2 drives the furnace body 1 to rotate so that the liquid in the furnace body 1 flows into the water immersion kettle 3 through the pouring port 11 .

[0030] In this embodiment, the lifting unit 4 drives the immersion kettle 3 to move up and down between the height flush with the ground and the first height below the ground by digging a foundation pit on the ground, the size of the foundation pit being 1350 mm long, 1230 mm wide, and 1300 mm deep. The lifting unit 4 is arranged in the foundation pit, thereby driving the immersion kettle 3 to move up and down in the foundation pit. The first height is preferably 1000 mm.

[0031] The specific working process of the device is as follows: precious metals and alkali are added into the furnace body 1, a heating module is provided in the furnace body 1, the precious metals in the furnace body 1 are heated, and after the precious metals are dissolved into liquid, the lifting unit 4 drives the water immersion kettle 3 to descend to a first height, and the first driving module 2 drives the furnace body 1 to rotate, so that the liquid in the furnace body 1 is poured into the water immersion kettle 3. After completion, the first driving module 2 drives the furnace body 1 to restore the initial state, and the lifting unit 4 drives the water immersion kettle 3 to rise to a height flush with the ground. The staff moves the water immersion kettle 3 out of the lifting unit 4 and moves it to the water immersion area, adds water to the melt in the water immersion kettle 3 for leaching, and then places the new water immersion kettle 3 on the lifting unit 4 to perform the next round of operation until the liquid in the furnace body 1 is completely poured out.

[0032] It should be noted that during the pouring process of the liquid in the furnace body 1, the liquid may splash out of the water immersion kettle 3. Therefore, when receiving the liquid, the water immersion kettle 3 will be lowered to the first height through the lifting unit 4. When the liquid splashes, the ground will block the liquid to prevent the liquid from directly splashing onto the ground or the staff, thereby improving production safety. Secondly, the pouring operation is achieved by lowering the water immersion kettle 3 instead of raising the furnace body 1 and other components, thereby reducing the overall height of the device, reducing costs, and improving safety.
