Description

Technical Field

[0001] This utility model relates to the technical field of metal electrolytic smelting equipment, and in particular to a disconnection device used in metal electrolytic production lines such as electrolytic manganese and electrolytic zinc to collect and intermittently discharge anolyte in order to reduce power consumption. Background Technology

[0002] In the hydrometallurgical processes of electrolytic manganese, electrolytic zinc, and other metals, fresh electrolyte is continuously fed into the electrolytic cell. Under the influence of direct current, metal is deposited at the cathode, while anolyte is produced at the anode. The anolyte is rich in soluble electrolytes such as sulfates and has good conductivity. In current production processes, the anolyte flows continuously through the anolyte chute on the electrolytic cell, enters the anolyte sluice, and is eventually returned to the preparation workshop.

[0003] This continuous flow of liquid creates a stable conductive path between the anolyte outlet and the anolyte trough, causing some current to bypass the normal electrode reaction and leak directly through this liquid path, resulting in unnecessary energy loss. This energy loss can account for a significant proportion of the overall power consumption, increasing production costs. Currently, there is a lack of a simple, externally powered device that can effectively solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide an anolyte flow interruption device to solve the problems of current leakage and serious energy waste caused by continuous anolyte outflow in the prior art. This invention utilizes the siphon principle to achieve automatic intermittent discharge of anolyte, effectively cutting off the conductive path during the discharge interval, thereby achieving energy saving.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: An anolyte flow interruption device, disposed in an anolyte chute below the anolyte outlet of an electrolytic cell, comprising a collection tank and a siphon tube. The collection tank has an opening at the top for receiving the anolyte flowing out from the anolyte outlet. The siphon tube is housed within the collection tank, with its inlet near the bottom of the collection tank and its outlet extending to the outside of the collection tank and connecting to the anolyte chute. The highest point of the siphon tube (siphon apex) is lower than the top of the collection tank but higher than its inlet.

[0006] Furthermore, the siphon tube is an inverted "U" shaped tube, with a simple and reliable structure. Furthermore, the cross-sectional area of ​​the collection box gradually decreases from top to bottom, forming a cone, bowl, or inverted frustum shape. This design facilitates flushing out sediment during the drainage stage, preventing sludge accumulation, and accelerates the siphon start-up process. Furthermore, the cross-section of the collection box is circular or a regular polygon, facilitating manufacturing and installation. Furthermore, the inlet of the siphon tube maintains a certain distance from the bottom of the collection box to prevent sediment from clogging the inlet. Furthermore, both the collection box and the siphon tube are made of corrosion-resistant plastics (such as PP, PVC) or fiberglass to withstand the corrosive environment of acidic anolyte. Furthermore, it also includes a liquid seal tank, with the outlet of the siphon tube submerged below the liquid surface within the tank. This design ensures that the siphon tube is always filled with liquid, facilitating rapid siphon start-up and enhancing operational reliability.

[0007] The working principle of this invention is as follows: Anode liquid continuously flows into the collection tank from the chute, and the liquid level in the tank rises slowly. This stage is the "liquid storage / flow interruption period," during which the liquid cannot flow out, the conductive path is cut off, and energy loss is reduced. When the liquid level exceeds the top of the siphon tube, the siphon effect is automatically activated, and the liquid in the tank is quickly drawn out. This stage is the "liquid drainage period." When the liquid level drops below the inlet of the siphon tube, air enters, the siphon effect is disrupted, drainage stops, and the device re-enters the "liquid storage / flow interruption period," thus repeating the cycle.

[0008] The beneficial effects of this utility model are as follows: 1. Significant energy saving effect: By physically changing the continuous flow to an intermittent flow, the conductive liquid path is completely cut off during the "liquid storage period" that accounts for most of the cycle, directly reducing the leakage loss of electrical energy from the source.

[0009] 2. Simple structure and low cost: The entire device consists of only a few parts such as a collection box and a siphon tube. There are no moving parts, no need for external power and complex control system, and the manufacturing, installation and maintenance costs are extremely low.

[0010] 3. Fully automatic operation, safe and reliable: It works entirely by relying on the fluid's own potential energy and the siphon principle, requiring no manual operation, with stable performance and a low failure rate.

[0011] 4. Wide adaptability and easy modification: The device can be directly installed below the anolyte chute of the existing electrolytic cell, with almost no impact on the original production process and layout, making it easy to promote and use in existing factories.

[0012] 5. Additional beneficial effects: The conical collection box design prevents solid matter from settling; the liquid seal tank design accelerates siphon start-up and makes the working cycle more stable. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. These embodiments are used to explain the present invention and do not constitute a limitation on the scope of protection.

[0016] Example 1: As Figures 1 to 3 As shown, the anolyte flow interruption device of this utility model is installed below the anolyte chute 5 of the electrolytic cell 4 in the electrolytic manganese workshop. The collection box 2 is a polygonal box made of corrosion-resistant polypropylene (PP) sheet welded together, and its upper diameter is larger than the diameter of the anolyte chute 5 to ensure that it can receive the entire liquid flow. The siphon pipe 3 is a PP pipe with an inverted "U" shaped structure. Its inlet 31 is suspended inside the collection box 2, about 5cm from the bottom of the box, to prevent manganese slag from accumulating and clogging. The outlet 33 of the siphon pipe 3 passes through the lower part of the side wall of the collection box 2 and is sealed to it. Externally, it is connected to the flange of the PP anolyte chute 32. The height (H) of the top bend of the siphon pipe 3 is designed according to the anolyte flow rate of the electrolytic cell to ensure sufficient "liquid storage / flow interruption" time.

[0017] Example 2: As Figure 4 As shown, in this embodiment, based on Embodiment 1, the collection box 2 is a circular box that tapers from top to bottom, and a liquid seal trough 6 is added below the liquid outlet 33 of the siphon tube 3. This liquid seal trough 6 is connected to the anolyte chute 32, and maintains a constant liquid level inside, ensuring that the liquid outlet 33 of the siphon tube 3 is always submerged below the liquid surface. This design pre-fills the siphon tube 3 with liquid, eliminating air gaps, and allowing the siphon effect to start instantly whenever the liquid level exceeds the siphon top, greatly improving the reliability and response speed of the device.

[0018] During use; liquid storage / flow interruption phase Figure 2 The anolyte flows into collection tank 2, causing the liquid level to rise. At this time, no liquid flows out, the conductive path is cut off, and energy is saved.

[0019] Siphon start-up and drainage stage ( Figure 3 Once the liquid level exceeds the height (H), the siphon action is activated, and the liquid is pumped out at high speed, causing the liquid level in the tank to drop rapidly.

[0020] Emptying and standby phase: After the liquid level drops below 31 at the inlet, air enters and the siphon stops. The device waits for the next liquid storage and the cycle begins.
