Description

Technical Field

[0001] This utility model relates to the field of water electrolysis hydrogen production technology, and in particular to a measuring tool for the liquid distribution module of the AEM water electrolysis hydrogen production electrolyzer. Background Technology

[0002] AEM (Alkaline Electrolysis) is a method for producing hydrogen by electrolyzing alkaline water. The electrolyzer has advantages such as small equipment size, high gas purity, and good compatibility with renewable energy sources, making it the main development direction for future electrolytic hydrogen production.

[0003] However, in existing AEM water electrolysis for hydrogen production, the electrolyzers are generally stacked vertically. The electrolyte enters from the top of the electrolyzer and then exits from the top. The direction in which the electrolyte enters each chamber is perpendicular to the flow direction of the electrolyte in the electrolyte channel. This top-in, top-out electrolyzer structure is prone to inconsistent electrolyte flow rates at the inlet of each chamber, resulting in different flow rates of electrolyte entering each chamber. The main reason is that eddies are generated during the flow of the electrolyte, affecting the flow rate into each chamber. Specifically, the electrolyte flow rate is moderate in the middle layer of the electrolyzer, slow in the top layer, and fast in the bottom layer. The AEM water electrolysis hydrogen production electrolyzer liquid inlet distribution module is a multi-segment curved surface structure used to improve the flow rate of electrolyte entering each electrolyzer chamber. When processing the AEM water electrolysis hydrogen production electrolyzer liquid inlet distribution module, the billet needs to be sampled and tested to prevent insufficient machining allowance of the forging billet. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a measuring tool for the liquid inlet distribution module of an AEM water electrolysis hydrogen production electrolyzer, which can solve the problem that the measuring tool structure used in general liquid inlet distribution modules can only detect the processed products and cannot detect the remaining processing of forging billets.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a detection measuring tool for the liquid distribution module of an AEM water electrolysis hydrogen production electrolyzer, the innovation of which is: including a guide plate assembly, a measuring unit and a connecting rope; The guide plate assembly includes a pair of guide plate units, which are mounted parallel to each other on a supporting base plate. There is a gap between the guide plate units to accommodate the liquid inlet dispensing module. Several vertically extending guide grooves are distributed on each guide plate unit along its extension direction, with the top of each guide groove penetrating the top of the guide plate unit. Support blocks for the liquid inlet dispensing module are provided at both ends of the guide plate assembly on the supporting base plate. Reference baselines are drawn on the sides of each guide groove on each guide plate unit. The measuring unit comprises several units, which are correspondingly arranged in each guide groove of the guide plate unit; the measuring unit includes a measuring base block and arc-shaped fitting teeth; the measuring base block is cuboid in shape, and the arc-shaped fitting teeth are several and vertically arranged on the measuring base block. The arc-shaped fitting teeth are strip-shaped, and one end away from the measuring base block has an arc-shaped curved surface for fitting with the curved surface of the liquid inlet distribution module; a rope threading hole is horizontally arranged on the measuring base block. The connecting ropes pass through the rope holes of each measuring base block in sequence, so that the measuring units corresponding to each guide groove on the guide plate unit are arranged in sequence.

[0006] Furthermore, if the difference between the distance between the end of the arc-shaped curved surface of the arc-fitting tooth and the surface of the measuring base block and the distance between the end of the arc-shaped curved surface of the arc-fitting tooth and the reference baseline on the guide plate unit is not less than 0, it indicates that the blank allowance of the liquid distribution module meets the processing requirements; otherwise, it does not meet the processing requirements.

[0007] Furthermore, a limiting sleeve is provided on the connecting rope between two adjacent measuring units, and the limiting sleeve is nested on the connecting rope. This is used to control the spacing between two adjacent measuring units to be consistent with the spacing between adjacent guide grooves on the guide plate unit, so as to ensure that the measuring unit can be quickly inserted into the guide groove of the guide plate unit.

[0008] The advantages of this utility model are: 1) This utility model is used to detect the machining allowance of the blank for the liquid inlet distribution module of the electrolyzer for hydrogen production by electrolysis of water. The arc-shaped surface on the detection unit contacts the surface of the liquid inlet distribution module and is compared with the reference baseline on the guide plate unit. If the upper surface of the measuring block is lower than the reference baseline, it means that the machining allowance of the blank is insufficient and unqualified; otherwise, it is qualified. This detection gauge can detect the machining allowance of important positions of the liquid inlet distribution module to ensure that there is enough machining allowance to mill out all positions during milling and to prevent some unqualified blanks from entering the machine tool for processing.
