Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cell assembly technology, specifically relating to an electrolytic cell stacking tool and an electrolytic cell stacking device. Background Technology

[0002] Hydrogen energy, as an ideal clean energy source, has enormous potential. Water electrolysis is a green method for producing hydrogen, and PEM (Polymer Electrolysis Membrane) water electrolysis is considered the most promising hydrogen production technology due to its high electrolysis efficiency, high power fluctuation matching degree, and high hydrogen purity. In a PEM water electrolysis unit, the PEM electrolyzer consists of several electrolyzers connected in series. The main components of the electrolyzer include membrane electrodes and plates. Current assembly processes involve repeatedly stacking membrane electrodes, plates, and other modules layer by layer to form a PEM electrolyzer structure containing multiple electrolyzers. To reduce stacking errors, guiding devices are usually installed at the stacking station to ensure the alignment of the electrolyzer meets design requirements. After stacking, the electrolyzer needs to be transported away from the stacking station, but the guiding devices can cause squeezing and friction on the electrolyzer, affecting the product performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] Reference Figure 1 This utility model provides an electrolytic cell stacking fixture 1, including a base plate 101 and multiple limiting posts 102. The limiting posts 102 are detachably installed on the base plate 101, and the multiple limiting posts 102 enclose each other on the base plate 101 to form a stacking station. The limiting posts 102 are generally installed vertically on the base plate 101, and their length and number are designed according to actual needs. During operation, the materials of the electrolytic cell are stacked and pressed sequentially in the stacking station to form an electrolytic stack. During the stacking and pressing process of PEM electrolytic cells, the multiple limiting posts 102 are spaced apart and enclosed outside the stacking station to limit the electrolytic stack, ensuring that the edges of the entire electrolytic stack are flush and the alignment meets the design requirements, thereby improving the overall stacking accuracy.

[0023] Specifically, the bottom of the limiting post 102 is provided with a mounting base 103; the mounting base 103 is provided with a mounting hole 104; the base plate 101 is provided with a positioning hole; the limiting post 102 is detachably mounted on the base plate 101 via a pin 105, the mounting hole 104, and the positioning hole. The pin 105 and the positioning hole serve a quick insertion / removal / positioning function. When the PEM electrolytic reactor is offline, the pin 105 is pulled out, and the outer limiting post 102 of the electrolytic reactor is removed to ensure that the electrolytic reactor will not be squeezed or rubbed against the limiting post 102.

[0024] To improve the applicability of the electrolytic cell stacking fixture 1, the base plate 101 is provided with multiple positioning holes; these positioning holes are arranged radially at intervals along the stacking station. Adjusting the positioning holes corresponding to the pins 105 can change the size of the stacking station and adjust the range of the guide and limiting area to accommodate electrolytic cells of different sizes. In another embodiment, multiple mounting holes 104 can be provided on the mounting base 103. By matching different mounting holes 104, the fixed position of the limiting post 102 can be changed, thereby adjusting the size of the stacking station.

[0025] In one detailed embodiment, the electrolytic cell stacking fixture 1 further includes a stacking base 108; the stacking base 108 is installed at the stacking station. During operation, materials are sequentially stacked and pressed on the stacking base 108.

[0026] Specifically, a lifting hole is provided on the base plate 101; the stacking seat 108 is provided on the lifting hole.

[0027] Furthermore, the electrolytic cell stacking fixture 1 also includes a lifting device 109; the lifting end of the lifting device 109 passes through the lifting hole and connects to the stacking base 108. The lifting device 109 enables the stacking base 108 to be raised and lowered. In use, the stacking base 108 is first raised to a high position, and when stacking each product, the stacking base 108 is lowered to a certain height to ensure the stacking height and the guiding positioning of the products within the stacking station.

[0028] In a preferred embodiment, the limiting post 102 is provided with a verticality adjustment pad 106 on the side facing the stacking station. By adjusting the verticality adjustment pad 106, the verticality of the limiting post 102 is ensured, thereby ensuring the alignment of the entire stack.

[0029] Since electrolytic reactors are generally tall, reinforcing ribs 107 are provided on the limiting post 102 to improve its strength.

[0030] Reference Figure 2 This utility model also provides an electrolytic cell stacking device, including a material handling device and the aforementioned electrolytic cell stacking fixture 1; the stacking station of the electrolytic cell stacking fixture 1 is located within the handling stroke of the material handling device. During operation, the material handling device sequentially transports materials to the stacking station for stacking and pressing.

[0031] Furthermore, the material handling device includes a material suction cup 3 and a moving platform 2; the material suction cup 3 is mounted on the moving platform 2; the stacking station is located within the moving stroke of the material suction cup 3. After the material suction cup 3 picks up the material, it is delivered to the stacking station via the moving platform 2. The moving platform 2 preferably includes a moving track, on which the material suction cup 3 is slidably mounted.
