[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a cathode liquid discharge tank, including a discharge tank body 1, the discharge tank body 1 is a vertical cylindrical structure, the top of the discharge tank body 1 is provided with a cone top 2, the cone top 2 is a cone structure assembled by a plurality of module plates 3, the tops of the module plates 3 connected to each other are provided with reinforcing angle steels 5, a sleeve 4 is provided at the center of the top of the cone top 2, the sleeve 4 is used as a connecting component of the discharge pipeline, so that the cathode liquid can flow out smoothly from the top of the discharge tank body 1 through the sleeve 4, that is, the sealing performance during the liquid discharge process is ensured, leakage is avoided, and it is convenient to connect with the external pipeline system, the reinforcing angle steels 5 are evenly arranged around the sleeve 4 as the center, and the discharge tank body 1 of this structure is assembled by arranging a plurality of module plates 3 on the top The cone top 2 is provided with a reinforcing angle steel 5 to reinforce the joints of the module plates 3. Compared with the cone top 2 of the whole structure, the module plates 3 are smaller in size and easier to manufacture, transport and install on site. For large discharge troughs, the logistics difficulty and cost can be significantly reduced. That is, the module plates 3 of the fan-shaped structure can be installed and fixed one by one on site, which is convenient for workers to operate. At the same time, if a certain module plate 3 is damaged, it can be replaced separately without replacing the entire cone top 2, which reduces the maintenance cost. The module plates 3 are all fan-shaped structures and are tightly connected to each other by welding, and the upper ends of the module plates 3 are welded and fixed to the outer wall of the sleeve 4. Each module plate 3 of this structure is tightly connected by welding to form a cone top of an integral stable cone structure. 2. Effectively disperse the top load and enhance the stability and durability of the structure. Several support angle steels 7 are welded and fixed around the top edge of the cylinder of the discharge trough main body 1. The positions of the support angle steels 7 and the outer ends of the reinforcement angle steels 5 correspond one by one. The support angle steels 7 of this structure can be connected and fixed with the outer ends of the reinforcement angle steels 5 to provide a stable support point, which can effectively enhance the overall rigidity and stability of the cone top 2. The support angle steel 7 can also be used as a mounting bracket to facilitate the fixing and hanging of various accessories, such as pipes, valves, sensors, walkways, ladders, etc., to facilitate the maintenance and operation of the discharge trough main body 1. The upper part of the cylinder of the discharge trough main body 1 is a thin-walled structure (the specific wall thickness is 8mm), and the upper and lower parts of the cylinder of the discharge trough main body 1 are both provided with reinforcement rings. 9. The reinforcing ring 9 is connected to the outer wall of the cylinder of the discharge trough main body 1 by welding. The upper part of the cylinder wall thickness of the discharge trough main body 1 of this structure is thinned to reduce the use of materials and reduce manufacturing costs. Reducing the wall thickness reduces the weight of the overall equipment, which is particularly important during transportation, installation and maintenance. It can reduce the requirements for the supporting structure and reduce transportation and lifting costs. At the same time, the discharge trough main body 1 can better match the actual stress conditions of different parts by thinning the upper wall thickness to achieve the optimal design of the structure. The reinforcing ring 9 can enhance the local strength and rigidity of the thinned area of ​​the upper part of the cylinder wall thickness of the discharge trough main body 1, especially when subjected to external forces in the vertical or horizontal direction. It can effectively prevent deformation and damage and ensure the stability of the overall structure of the discharge trough.A manhole 6 is provided on one side of the top of the cone top 2, and a reinforcement ring is provided at the connection between the manhole 6 and the cone top 2. The manhole 6 of this structure can be used as an openable entrance at the top of the cone top 2, allowing staff to enter and exit, which is convenient for inspection, maintenance, cleaning or repair work inside the discharge tank body 1. The manhole 6 can be opened to help the inside of the discharge tank body 1 to exchange air with the outside world, which is beneficial to the dispersion of volatile gases, reduce internal pressure, and improve work safety. The reinforcement ring at the connection between the manhole 6 and the cone top 2 can effectively disperse the stress concentration at the opening, enhance the pressure bearing capacity around the manhole 6, and ensure the overall strength and stability of the cone top 2. The reinforcement ring not only strengthens the structure, but also cooperates with the manhole cover and Gaskets and other sealing elements ensure the sealing of the manhole 6 when it is closed to prevent liquid leakage or external contaminants from entering. Especially in containers storing corrosive or harmful substances, sealing is particularly important. Four lifting lug assemblies 8 are welded and fixed around the outer wall of the upper cylinder of the discharge tank body 1. The lifting lug assemblies 8 of this structure can be used as the connection point of lifting equipment such as cranes and cranes, so that this large discharge tank body 1 can be safely and stably lifted during installation, relocation or maintenance. In addition, during equipment maintenance or internal cleaning, the lifting lug assemblies 8 can be used to assist in moving the discharge tank body 1 or adjusting its position, so that the staff can approach the part that needs maintenance, thereby improving work efficiency and safety.

[0018] Working principle: When using the cathode liquid discharge tank, first, after the discharge tank body 1 is prefabricated as a whole, the cone top 2 is installed on the top thereof. When the cone top 2 is installed, it is assembled with a plurality of module plates 3. Each module plate 3 is tightly connected by welding, and the upper ends of the module plates 3 are welded and fixed on the outer wall of the sleeve 4. Then, the reinforcing angle steel 5 is welded at the connection of the module plates 3. During the welding process of the reinforcing angle steel 5, the bottom end is welded to the supporting angle steel 7. In this way, the supporting angle steel 7 can provide a stable support point for the reinforcing angle steel 5, enhance the overall rigidity and stability of the cone top 2, and at the same time, the upper and lower parts of the cylinder of the discharge tank body 1 are welded. Reinforcement rings 9 are welded on the outside, which improve the local strength and rigidity of the area where the wall thickness of the upper part of the discharge trough body 1 is thinned. When the staff needs to enter the discharge trough body 1 for inspection, maintenance, cleaning or repair work, the manhole 6 can be opened as an entrance, and when the discharge trough body 1 as a whole needs to be shifted, the lifting ear assembly 8 can be used as a connection point for lifting equipment such as a crane or a crane, and can be lifted and moved in a stable and safe manner. When the discharge trough body 1 is in use, the sleeve 4 is used as a connecting part of the discharge pipe, so that the cathode liquid can flow smoothly out from the top of the discharge trough body 1 through the sleeve 4, thereby completing a series of work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
