Embodiment Construction

[0021] The specific implementation will be described below in conjunction with the accompanying drawings.

[0022] In this embodiment, the pressure filter type water electrolyzer is as figure 1 As shown, it includes a front end plate 1 and a rear end plate 2 located at both ends of the electrolytic cell, several electrolytic chamber components 3 arranged between the front end plate 1 and the rear end plate 2 and stacked in sequence, several groups of the front end plate 1 and the rear end plate The end plate 2 is locked and connected with an insulating pull rod assembly 4 . The electrolysis cell assembly 3 is composed of a frame, electrode plates, diaphragms and other components arranged in the frame. The positive and negative terminal plates of the electrolytic cell are arranged at both ends of the electrolytic cell, and direct current is connected to realize the electrolysis of water to generate hydrogen and oxygen.

[0023] Such as figure 2 image 3 As shown, the insula...

Abstract

The invention relates to a filter-pressing type water electrolyser, and aims to solve the problem of difficult insulation treatment due to the fact that positive and negative electrode wiring boards are arranged at the two ends of an existing electrolyser, the insulation requirement for a pull rod assembly is high, and the length of the electrolyser changes in the using process. The filter-pressing type water electrolyser provided by the invention comprises two end plates at two ends, a plurality of small electrolysis chambers between the two end plates, and a plurality of groups of insulating pull rod assemblies for locking and connecting the two end plates, wherein each insulating pull rod assembly comprises a pull rod with threads at two ends, a locking nut matched with the pull rod, insulating pads sleeved at two ends of the pull rod, and a waterproof insulating sleeve sleeved on the pull rod, wherein two ends of the waterproof insulating sleeve are respectively and tightly matched and sleeved with the insulating pads, and the insulating pads are positioned between the adjacent end plates and the locking nut; and the end part of the pull rod and the locking nut are positioned in a water retaining protective cap which is fixedly arranged on the insulating pad. The pull rod is completely sealed in the insulation component, the insulation is reliable, and the current can be directly loaded at the two ends of the electrolyser.

Description

technical field [0001] The invention relates to an electrolytic hydrogen production device, more specifically, to a filter press type water electrolyzer. Background technique [0002] In the existing filter press water electrolyzer, the two ends of the electrolyzer are end plates, and several frames for supporting and containing each water electrolysis chamber are stacked between the two end plates, and the two end plates are tensioned by a tie rod assembly. so that the frames are pressed against each other. [0003] There are two arrangements of the positive and negative electrode terminal boards of the existing electrolyzer. One of them is that the positive terminal terminal is arranged in the middle of the electrolytic tank, and the negative terminal terminal is arranged at the two ends of the electrolytic tank. In the electrolytic cell with this arrangement of electrode terminal boards, since the polarity of the electrodes at both ends of the electrolytic cell is the sa...
