[0002] With the continuous growth of energy demand and the development of renewable energy technology, flow batteries are gaining increasing attention as an efficient and scalable energy storage solution.
[0003] In a flow battery system, the PP (polypropylene) tank is a key component, and its performance is directly related to the stability and efficiency of the entire system. Its primary function is to safely store electrolyte, ensuring a stable and continuous supply of electrolyte to the battery stack during the charge and discharge process. At the same time, the PP (polypropylene) tank must also have excellent sealing properties to prevent electrolyte leakage and the ingress of external impurities, thereby ensuring the normal operation and safety of the battery system.
[0004] The storage tank used for liquid flow batteries has other components installed inside the tank, which is convenient for heat exchange pipes, etc. Therefore, during the production process, the ends of the tanks are all opened and then sealed and fixed. Here, the structural strength of the ends of the tanks needs to be ensured. Summary of the Invention
[0005] To address the aforementioned issues, the present invention discloses a large-scale polypropylene storage tank device comprising a polypropylene tank body with a sealing plate embedded and fixedly connected at each end. A plurality of horizontally arranged reinforcing ribs are fixedly connected to the outer sides of the sealing plate, with the edges of the reinforcing ribs flush with the ends of the tank body. The reinforcing ribs are single-plate members, fixedly connected to the sealing plate on one side and to the inner wall of the tank body at both ends. This arrangement significantly improves the structural strength of the ends of the tank body.
[0006] Guard plates are installed above and below the edges of the reinforcement ribs. Bolts and nuts are inserted into the guard plates and fixed to the reinforcement ribs through the bolts and nuts. The guard plates are used to protect the unattached edge on the other side of the reinforcement ribs and further enhance the structural strength of the end of the tank.
[0007] Preferably, a first vertical pipe and a second vertical pipe are provided inside the tank body, and the first vertical pipe and the second vertical pipe are respectively located at both ends of the tank body. The first vertical pipe and the second vertical pipe are used for the inlet and outlet of the electrolyte, and are located at the ends of the tank body to ensure that the electrolyte can gradually flow from one end to the other.

In other words, the first and second horizontal tubes are used for delivering and receiving electrolyte.
[0009] Preferably, a plurality of baffles are fixedly connected to the interior of the tank at equal distances. The baffles not only improve the structural strength of the tank, but also change the flow direction of the electrolyte inside the tank.
[0010] Preferably, a manhole is provided on one side wall of the tank body so that personnel can enter the tank body for production maintenance and the like.
[0011] Preferably, a heat exchange tube is provided inside the tank, and a medium is passed through the heat exchange tube to change the temperature of the electrolyte, thereby facilitating the operation of the flow battery.
[0012] Preferably, a nozzle is provided at one end of the tank body. The nozzle is a reserved setting that can be used to drain the internal electrolyte, install a pressure relief valve, etc. If it is not in use, it needs to be blocked.
[0013] The beneficial effects of the present invention are as follows:
[0014] 1. Reinforcement ribs and guard plates are provided at the ends of the tank body, which, together with the sealing plate, greatly improve the structural strength of the end of the tank body.
[0015] 2. A heat exchange tube is provided inside the tank body, which changes the temperature of the electrolyte by introducing a heat medium or a coolant, thereby being more conducive to the operation of the flow battery. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.
[0022] like Figures 1 to 3 As shown, a large polypropylene storage tank device includes a tank body 2 made of polypropylene. The tank body 2 is cylindrical, and both ends of the tank body 2 are embedded and fixedly connected with a sealing plate 1, that is, the sealing plate 1 is a plug at both ends of the tank body 2. The outer side of the sealing plate 1 is fixedly connected with a plurality of mutually horizontally arranged reinforcing ribs 9, and the edge of the reinforcing rib 9 is flush with the end of the tank body 2. The reinforcing rib 9 is a plate, and one side of the plate is fixedly connected to the sealing plate 1, and both ends of the plate are fixedly connected to the inner wall of the tank body 2. This arrangement greatly improves the structural strength of the end of the tank body 2 and ensures the stability of the end of the tank body 2.
[0023] Guard plates 10 are provided above and below the edges of the reinforcement rib 9. The guard plates 10 are also plates. At the same time, the plates are narrow and are clamped on the edges of the reinforcement rib 9 to protect the reinforcement rib 9. Bolts and nuts 11 are inserted into the guard plates 10, and the guard plates 10 are fixedly connected to the reinforcement rib 9 by the bolts and nuts 11. Therefore, the guard plates 10 are provided on the reinforcement rib 9, which also improves the structural strength of the end of the tank body 2.
[0024] A first vertical pipe 3 and a second vertical pipe 6 are provided inside the tank body 2. The first vertical pipe 3 and the second vertical pipe 6 are used for the input and output of the electrolyte, and the first vertical pipe 3 and the second vertical pipe 6 are respectively located at the two ends of the tank body 2. The arrangement at both ends can realize the gradual flow of the electrolyte from one end to the other end. The side walls of the first vertical pipe 3 and the second vertical pipe 6 are evenly provided with through holes, and the through holes are arranged for entering and exiting the vertical pipes. A first transverse pipe 12 is fixedly connected to the first vertical pipe 3, and a second transverse pipe 13 is fixedly connected to the second vertical pipe 6.
