Description

Technical Field

[0001] This utility model belongs to the field of rapid heating and temperature control of cathodic liquid, and in particular relates to a cathodic liquid heating and temperature control component. Background Technology

[0002] The electrolytic refining process of non-ferrous metal wet soluble anode nickel involves placing nickel sulfide anode plates, produced by pyrometallurgical processes, into an electrolytic cell as raw material anodes. The cathode is a nickel starting sheet produced from a seed plate cell, placed in a diaphragm bag. Qualified catholyte flows from the catholyte storage tank, after acid adjustment and heating, into the cathode diaphragm bag of the electrolytic cell. Under the action of direct current, nickel ions in the catholyte are deposited at the cathode, yielding the finished electrolytic nickel. However, to ensure the catholyte temperature remains consistently around 68°C, a catholyte temperature control component is urgently needed to guarantee temperature control of the catholyte. Utility Model Content

[0003] This invention features an electric heating wire laid around the perimeter of the elevated tank to ensure temperature control of the catholyte. Double U-shaped electric heating tubes are added inside the tank for double-sided electric heating, and heating devices are installed at the inlet and outlet to ensure that the catholyte temperature can be raised in multiple ways.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cathode liquid heating and temperature control component, comprising a tank, an electric heating wire, a double U-shaped electric heating tube, a first disc-type electric heating coil, and a second disc-type electric heating coil; The electric heating wire is sleeved on the outer wall of the tank; The double U-shaped electric heating tube is inserted into the tank and fixedly connected to the inner wall of the tank. The first disc-shaped electric heating coil is fixedly installed at the liquid inlet of the tank, and the second disc-shaped electric heating coil is fixedly installed at the liquid outlet of the tank.

[0005] The electric heating wire includes three horizontally parallel electric heating wires with equal spacing. Adjacent electric heating wires are electrically connected by wires with a spacing of 500mm.

[0006] The electric heating wire is fixed to the outer wall of the tank by wrapping it with insulating cotton.

[0007] The double U-shaped electric heating tube is fixed inside the tank by screws.

[0008] Through the above design scheme, this utility model can bring the following beneficial effects: This invention relates to a cathode liquid heating and temperature control component. The heating design is based on the shape of a tank, unlike ordinary heating tubes. Electric heating wires are installed on the outer perimeter of the tank to maintain its temperature, while double U-shaped electric heating tubes are added inside the tank for internal heating. This achieves dual heating from both inside and outside, ensuring rapid temperature rise while preventing temperature loss due to external temperature influences. Furthermore, the first and second disc-shaped electric heating coils at the inlet and outlet effectively increase the rate of liquid heating. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram, 1 – tank body, 2 – electric heating wire, 3 – double U-shaped electric heating tube, 4 – first disc-type electric heating coil, and 5 – second disc-type electric heating coil. Detailed Implementation

[0010] The present invention will be further described below with reference to specific embodiments, but the embodiments do not limit the present invention in any way.

[0011] A cathode liquid heating and temperature control assembly includes a tank 1, an electric heating wire 2, a double U-shaped electric heating tube 3, a first disc-type electric heating coil 4, and a second disc-type electric heating coil 5. The electric heating wire 2 is sleeved on the outer wall of the tank body 1; The double U-shaped electric heating tube 3 is inserted into the tank 1 and is fixedly connected to the inner wall of the tank 1. The first disc-type electric heating coil 4 is fixedly installed at the liquid inlet of the tank 1, and the second disc-type electric heating coil 5 is fixedly installed at the liquid outlet of the tank 1.

[0012] The electric heating wire 2 includes three horizontally parallel electric heating wires with equal spacing. Adjacent electric heating wires are electrically connected by wires with a spacing of 500mm.

[0013] The electric heating wire 2 is fixed to the outer wall of the tank 1 by wrapping it with insulating cotton.

[0014] The double U-shaped electric heating tube 3 is fixed inside the tank 1 by screws.

[0015] The design of this utility model, which uses an electric heating wire 2 installed outside the tank and a double U-shaped electric heating tube 3 installed inside the tank, can effectively avoid the impact of losing steam heating on on-site production, protect the continuity of production, and reduce product quality problems caused by the lack of steam. Because the design of this utility model can both avoid heat loss on the outside of the tank and heat the liquid inside the tank, the first disc-type electric heating coil 4 and the second disc-type electric heating coil 5 installed at the liquid inlet and liquid outlet can also effectively improve the liquid heating speed and ensure the production process's requirements for liquid temperature. Example

[0016] When repairing the steam supply system in the plant (each repair session lasts approximately 3 hours), before using the device of this invention, it was necessary to simultaneously reduce the catholyte flow rate and lower the electrolytic nickel current because temperature stability could not be guaranteed. This not only slowed down the growth rate of electrolytic nickel but also affected product quality (e.g., the appearance of sandwich panels).

[0017] After implementing this device, even without a steam supply, the cathode liquid temperature can be stabilized at around 68°C without reducing the current and flow rate, ensuring normal electrolytic nickel production and guaranteeing product quality. Furthermore, the device is simple to manufacture, uses inexpensive materials, and does not require periodic replacement, further reducing product quality issues while ensuring continuous production.

[0018] In actual production, the liquid contains high levels of chloride ions, making it highly corrosive. To prevent corrosion of the heating tubes inside the tank, titanium spherical heating tubes are selected. This material is corrosion-resistant, lightweight, and easy to use and maintain. Actual field use has demonstrated that it effectively ensures temperature rise and avoids the drawback of insufficient cathode liquid temperature when steam is shut off. This reduces the risk of electrolytic nickel layering caused by insufficient steam, ensuring a normal supply of liquid for electrolytic nickel production. Avoiding these problems provides a strong guarantee for protecting the quality of electrolytic nickel products.
