Description

Technical Field

[0001] This utility model relates to the fields of metal purification technology and electrochemical smelting, specifically to a water cooler with a metal purification lining. Background Technology

[0002] High-purity metals refer to materials with fewer impurities and higher metal purity, and their performance is superior to that of ordinary metals.

[0003] Generally, different technical methods are used depending on the purity of the raw materials and the quality requirements of the finished products. A single purification method is insufficient for producing high-purity, especially ultra-high-purity, iron; therefore, a combination of technologies is typically required. However, the impact of the preparation process on the quality of pure iron, particularly the contamination of the container material by the purified metal, cannot be ignored. Preliminary research suggests that processes such as plasma arc furnaces and induction melting furnaces can reduce the introduction of impurities during the process, but the significant increase in cost hinders their application and widespread adoption. Therefore, exploring metal purification technologies that reduce both process contamination and costs is a pressing issue for those skilled in the art. Utility Model Content

[0004] Based on a systematic study of the metal purification mechanism and process, this invention addresses the issue of container material contamination of hot metal during the metal purification process by providing a water-cooled liner for metal purification. Specifically, a water-cooled liner is installed inside the purification container. The hot working surface in contact with the liquid metal is a copper plate, while the cold surface in contact with the container is a steel plate. A serpentine water-cooling pipe is laid inside the water-cooled liner to conduct heat, enabling stable and low-cost operation of the purified metal without contamination.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A water cooler based on a metal purification lining is characterized by comprising a water supply and heat dissipation unit and a metal purification lining in sequence.

[0007] The water supply and heat dissipation unit includes a water supply end, a new water loop pipe, and a water cooler, a return water loop pipe, and a drain end connected thereto. Water enters the new water loop pipe through the water supply end, then passes through the water cooler for heat exchange, and finally exits through the return water loop pipe and the drain pipe; the water cooler is equipped with serpentine water cooling pipes to increase heat conduction.

[0008] The metal refining liner unit includes a refining container, with a water cooler embedded inside. The water cooler includes a cold surface and a hot surface. Softened water, treated with softening processes, is supplied to the water supply end. The drainage end connects to a closed-loop soft water system, where the soft water is pressurized and recycled. The hot surface of the water cooler, i.e., the cold surface in contact with the refining container, is made of steel plate to stabilize the basic structure and reduce deformation.

[0009] Furthermore, the water cooler is equipped with serpentine water cooling pipes to conduct heat away.

[0010] Furthermore, the water supply is softened water to prevent scale buildup inside the serpentine water-cooling pipes, which would affect the heat conduction effect.

[0011] Furthermore, the drainage end is connected to a closed soft water system for pressurized recycling.

[0012] The metal refining liner unit includes a refining container and multiple water coolers embedded therein, consisting of a cold water cooler surface and a hot water cooler surface that form components therewith.

[0013] Furthermore, the hot surface of the water cooler, that is, the working surface in contact with the purified molten metal, is made of copper plate to ensure that its thermal conductivity reaches more than 45W / (mk) under normal temperature conditions.

[0014] Furthermore, by using steel plates as the material for the hot surface of the water cooler, which is the cold surface in contact with the container, the basic structure can be stabilized and prevent deformation, and the investment cost can be significantly reduced.

[0015] Furthermore, at the copper-steel interface of the water cooler, welding or other treatment processes are used to achieve full penetration bonding.

[0016] Furthermore, the cooling soft water in the new water ring pipe is supplied to the serpentine heat dissipation water pipe through the inlet pipe. The heat generated during the metal purification process is conducted to the serpentine heat dissipation water pipe through the hot surface of the water cooler, and is carried out by the soft water and discharged into the return water ring pipe through the outlet pipe for recycling.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention provides a water cooler with a copper-steel lining based on metal purification, which avoids recontamination of high-purity metals during the metal purification process, significantly reduces the investment cost of process equipment, improves the structural stability of the water cooler lining, and enables stable and low-cost operation of purified metals under high-temperature conditions.

Detailed Implementation

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , 2 As shown, a water-cooled cooler based on metal refining includes a refining container 3 and multiple sets of water coolers 4 embedded therein, consisting of a cold surface 8, a serpentine heat dissipation pipe 9, and a hot surface 10 of the water cooler forming components therewith. Cooling soft water is supplied into the new water ring pipe 2 through the water supply end 1, and then supplied to the serpentine heat dissipation pipe 9 through the water inlet pipe 7. Part of the heat generated during the metal refining process is conducted to the serpentine heat dissipation pipe 9 through the hot surface 10 of the water cooler. The heat is carried out by the cooling soft water through the water outlet pipe 12, and the cooling soft water is discharged into the return water ring pipe 5 and then supplied to the recycling system through the drain end 6.

[0024] To ensure the heat conduction effect of the water cooler 4, after laying serpentine heat dissipation water pipes 9 inside the water cooler 4, the gaps between the serpentine heat dissipation water pipes 9 are filled with molten copper. After the molten copper cools and solidifies, a steel plate is welded to the cold surface 8 of the water cooler for shaping. At the steel joint surface 11 of the water cooler 4, welding or other treatment processes are used to achieve full penetration bonding.

[0025] The softened cooling water has removed calcium and magnesium ions from the water, reducing the water hardness. The inlet water temperature is below 8℃. It is supplied to the new water ring pipe 2 through the water supply end 1, effectively transferring the heat from the serpentine heat dissipation pipe 9. The water temperature difference is maintained within 3℃, preventing scale buildup on the inner wall of the serpentine heat dissipation pipe 9.

[0026] The heat generated during the metal refining process is conducted to the serpentine heat dissipation water pipe 9 through the hot surface 10 of the water cooler, and then carried out by the soft water and discharged into the return water ring pipe 5 through the outlet pipe 12 for recycling.

[0027] This invention provides a water cooler with a copper-steel lining based on metal purification. While ensuring that the metal purification process does not contaminate the high-purity metal, it significantly reduces the investment cost of process equipment and improves the structural stability of the water cooler lining.
