There is. The electrolysis chamber unit of this electrolyzer (Figs. 5 and 6)
The drawing shows a frame-like shape in which a rectangular tube-shaped electrolyte passage is formed in the periphery thereof, and the feeding tube B for fixing the penetrating rod B through the upper and lower surfaces of the rectangular tube passage A at the lower part thereof. A through hole C having the same diameter as that of the rectangular tubular passage A between adjacent power feed rods B is formed.
A plurality of electrolytic solution supply holes D and D'are linearly formed on the upper surface of the. Therefore, when manufacturing the rectangular tubular passage A, a large-diameter through hole C having the same diameter as that of the power feeding rod B and small-diameter supply holes D and D'must be formed, which is troublesome in manufacturing. There are drawbacks. Further, as shown in the figure, the current distribution member E connected to the power feeding rod B functions so that the inside of the electrolytic solution serves as a downcomer (downward flow path) of the electrolytic solution. Therefore, the electrolytic solution supplied from one of the supply holes D and D ', which is located below the current distribution member E, collides with the electrolytic solution descending in the current distribution member E to disturb the liquid flow. There is a drawback that it causes.

に好ましい。The current-carrying rod is connected to the electrode plate via the current distribution member except for the lower part, and the lower end part is fitted and fixed in the lower surface through hole provided in the lower surface of the cylindrical electrolytic solution supply part, and the side surface of the electrolysis chamber is also fixed. The large-diameter large-diameter through-hole is inserted with a gap at a predetermined position on the peripheral surface thereof. For example, one or more plugs may be attached to the large-diameter through hole, and the current-carrying rod may be fixed to the large-diameter through hole via the plug. In this case, the plug shall be in close contact with both the large-diameter through-hole and the current-carrying rod so that the current-carrying rod can be firmly fixed to the frame-like frame, and the entire space between the periphery of the large-diameter through-hole and the current-carrying rod should be secured. A vertical electrolytic solution flow passage for supplying the electrolytic solution in the cylindrical electrolytic solution supply path to the electrolytic chamber is partially formed without blocking. One or two or more plugs can be used per large-diameter through-hole, but two plugs with a cross section of a semicircular donut shape are arranged around the current-carrying rod so that their ends are separated from each other. It is preferable to form two flow passages. Further, the position around the current-carrying rod that forms the flow passage is not limited, but, as will be described in detail later, it should be almost directly below the current-carrying rod-joining peripheral surface portion where the current-carrying rod and the current distribution member are joined. Is preferable for achieving smooth circulation of the electrolytic solution.

ため、製造工程が簡略化され製造コストも低減される。The filter press type electrolytic cell of the present invention has only a through hole for inserting a current-carrying rod through the side surface of the hollow lower electrode frame body in the electrolytic chamber when the flow path of the electrolytic solution to the electrolytic chamber is produced. It suffices, and it is not necessary to form a through hole for circulating the electrolytic solution, so that the manufacturing process is simplified and the manufacturing cost is reduced.
