Description

Technical Field

[0001] The invention relates to the technical field of metal component welding, and in particular to welding equipment used for connecting a main pole plate and a plate frame of an electrolytic cell. Background Art

[0002] Hydrogen production by water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed into an electrolytic cell filled with electrolyte, and water molecules undergo electrochemical reactions on the electrodes, decomposing into hydrogen and oxygen.

[0003] There are three main technologies for producing hydrogen by electrolysis of water: alkaline electrolysis, proton membrane electrolysis, and high-temperature electrolysis. Among them, high-temperature electrolysis technology has high efficiency and low energy consumption, but high investment cost; proton membrane electrolysis technology has a fast start-up time, but relatively high efficiency and energy consumption; alkaline electrolysis technology has the lowest investment cost, but is not as good as the other two technologies in terms of efficiency and energy consumption. In the existing large-scale process of producing hydrogen by electrolysis of water, the low-cost alkaline electrolysis technology is mostly used.

[0004] The core component of alkaline electrolysis technology is the electrolyzer, which mainly includes plates, frames, diaphragms, electrodes and BOP auxiliary systems. Among them, plates and frames are supporting components in the electrolyzer, used to support electrodes and diaphragms, and conduct electricity; the main function of the diaphragm is to prevent hydrogen and oxygen from mixing; the electrode is the place where the electrochemical reaction occurs, and it is also the key to determining the efficiency of hydrogen production in the electrolyzer; the BOP auxiliary system includes power supply system, control system, gas-liquid separation system, purification system, alkali system, water replenishment system, cooling and drying system and other auxiliary systems.

[0005] The pole plate is a circular plate in appearance, generally made of cast iron metal plate, nickel plate or stainless steel metal plate, which is punched into a nipple structure through machining, and then welded to the pole frame and nickel-plated; the pole frame is an annular frame with airway holes and liquid channel holes. The part welded to the main pole plate is called the tongue plate of the pole frame. The outermost side of the pole frame is the sealing line area, and the rest is the overlapping area of ​​the diaphragm and the sealing gasket. After the main pole plate and the pole frame are processed separately, the pole frame and the main pole plate are welded together through the tongue plate of the pole frame to form an integrated pole plate. The quality of welding will directly affect the overall performance of the pole plate.

[0006] When the existing automatic welding machine is used to weld the main pole plate and the pole frame, the following problems often occur:

[0007] 1. The welding method is single, and it is difficult to achieve welding processing along a specific path. Specifically, since the main pole plate is a circular plate in appearance, and the pole frame is an annular frame in appearance, the joint between the main pole plate and the pole frame is an annular joint. During the welding process, circumferential ring welding is required along the joint, and the existing welding machine can usually only achieve mobile welding along a straight path, and when performing annular welding between the main pole plate and the pole frame, welding missing problems are prone to occur.

[0008] 2. The welding operation of the replacement side is inconvenient. Specifically, in order to increase the firmness of the connection, the main pole plate and the pole frame usually need to adopt a double-sided welding process, which requires the main pole plate and the pole frame to be disassembled and reinstalled after the single-sided welding is completed. The operation is cumbersome and easily leads to welding deviation.

[0009] 3. The feeding, conveying, clamping and positioning of the main pole plate and pole frame are inconvenient. Specifically, during the welding process, the main pole plate and pole frame need to be fed and clamped separately, and the setting of the feeding and clamping positioning mechanism cannot hinder the feeding of the welding mechanism. In addition, due to the special appearance of the main pole plate and pole frame, it is difficult to achieve accurate clamping of the main pole plate and pole frame using common fixtures or feeding methods.

[0010] 4. The adjustability of welding is poor, and it is difficult to achieve adaptive welding for main plates and pole frames of different sizes.

[0011] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
