Description

Technical Field

[0001] This utility model relates to the field of hydrogen production by water electrolysis, and in particular to a limiting device for the electrode plate frame of an electrolyzer. Background Technology

[0002] In the electrolysis process, the non-ferrous metal products adsorbed on the electrode plates need to be stripped off periodically. This process involves lifting the electrode plates placed on the electrode plate frame out of the electrolytic cell, stripping off the metal, and then putting the electrode plates back into the electrolytic cell. This process mainly relies on the worker's skill. The crane is manually lowered little by little, which can easily lead to the electrode plate frame being misaligned, damaging the anti-corrosion layer inside the electrolytic cell and causing a leakage accident.

[0003] Conventional electrolytic cell electrode plate limiting structures often adopt a point-to-point structure, which is difficult to achieve stable positioning, especially when there are many electrode plates. Stacked structures often lead to a reduction in installation accuracy.

[0004] There is a need for an electrolytic cell electrode frame limiting device to solve the above problems. Utility Model Content

[0005] This invention addresses the problem that conventional electrolytic cell electrode plate limiting structures in the prior art often employ a point-to-point structure, which makes it difficult to achieve substantial stable positioning. In particular, when there are many electrode plates, the stacked structure often leads to a reduction in installation accuracy. This invention provides an electrolytic cell electrode plate frame limiting device that solves the above problems by adopting a sliding limiting structure.

[0006] This utility model provides an electrolytic cell electrode frame limiting device, including a positioning part and a functional part. Both the positioning part and the functional part are plate structures. The positioning part is disposed on the outer periphery of the functional part and has an annular structure. The reference surfaces of the positioning part and the functional part are disposed in the same plane. The positioning part is provided with a plurality of positioning holes, a plurality of pairs of guide grooves, and a plurality of pairs of guide blocks. The pairs of guide grooves and pairs of guide blocks are symmetrical about the center of the positioning part. The guide grooves and guide blocks are staggered. The positioning holes are disposed between the guide grooves and guide blocks.

[0007] In a preferred embodiment of the electrolytic cell electrode frame limiting device described in this utility model, the positioning part includes a frame, a guide groove, a guide block, and a positioning hole. The frame is an annular structure. The guide groove and the guide block are structures generated on both sides of the frame by the same structure through concave-convex deformation. The guide groove and the guide block are staggered and symmetrically arranged based on the center of the frame. The reference line in the length direction of the guide block and the reference line in the length direction of the guide groove both coincide with the annular reference line of the frame. The positioning hole is located between the guide block and the guide groove. The guide groove is an arc-shaped groove of equal width. The depth of the guide groove increases sequentially from the two short sides towards the center, forming two inclined surfaces. The depth of the long side edge of the guide groove increases linearly towards the reference line. The sum of the widths of the inclined surfaces of the two long sides of the guide groove is less than the width of the guide groove. The shape of the guide block matches the guide groove.

[0008] In a preferred embodiment of the electrolytic cell electrode frame limiting device described in this utility model, the midpoint of the guide groove in the reference direction is a spherical or arc-shaped surface at the intersection of the two short inclined surfaces.

[0009] In a preferred embodiment of the electrolytic cell electrode frame limiting device described in this utility model, the positioning part is made of ABS plastic.

[0010] The beneficial effects of this utility model are as follows:

[0011] (1) This device uses an arc groove to guide the block of the corresponding structure. Based on the shared use of arc guideline and centripetal inclined surface, the guide block can meet the requirement that the force applied to the plate can move in one direction when a vertical force is applied to the plate surface, regardless of the initial contact position. Rotation is the main force, which is simple and quick to connect and realizes rapid installation.

[0012] (2) This device uses a spherical contact point to avoid the two devices shaking with each other after installation. The spherical contact surface can provide more stable contact guidance. Attached Figure Description
