Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell equipment, in particular to a head plate structure for an electrolytic cell. Background Art

[0002] In existing production technology, the common electrolytic cell is an open electrolytic cell. Due to the slow flow rate of the electrolyte, it is difficult to ensure a uniform flow rate of the liquid, and uneven flow and dead corners are prone to occur. Not only does it make the current distribution on the electrode uneven, resulting in a decrease in the electrolysis current density, but also due to the slow flow rate, the laminar layer on the electrode surface is wider, which makes the concentration of the electrolyte on the electrode plate surface lower, thereby causing concentration polarization, increasing the cell voltage, and increasing the chance of side reactions, thereby limiting the increase in current density during electrolysis. In electrolysis projects, the electrolytic cell is the key to investment, especially the area of ​​the electrode, which increases the cost of the electrolytic cell. Therefore, under the condition of ensuring a certain scale of equipment, increasing the unit production capacity and reducing the electrode area are the keys to reducing investment. In addition, the existing electrolytic cells are open, and the gas generated during electrolysis will carry the electrolyte and evaporate into the factory, resulting in a poor operating environment in the electrolysis plant.

This device mainly solves the technical problems of poor production capacity and output of existing electrolytic cells. The device discloses a head plate for the electrolytic cell, wherein the liquid flow port on the existing head plate cannot adjust the aperture size, resulting in that in actual use, the aperture cannot be adjusted during the installation process according to actual needs, resulting in the inability to adjust the discharge flow.

[0029] In this embodiment, by opening a liquid inlet hole 11 on the plate body 1, it is convenient for liquid to enter the interior of the plate body 1, pass through the liquid guide channel 12, and then be discharged outward from the liquid discharge hole 13.

By arranging a clamping member 23 on the outer periphery of the cylinder body 22, the blocking end 24 can be conveniently clamped.

[0030] In one embodiment, see Figure 2In order to improve the assembly efficiency of the mounting ring 21, a plurality of threaded holes 111 are opened in the circumferential direction of the outer periphery of the liquid inlet hole 11, and a plurality of connecting holes 211 that cooperate with the threaded holes 111 are opened on the mounting ring 21. The liquid discharge port 223 includes a first liquid discharge outlet 2231 and a second liquid discharge outlet 2232.

[0031] In this embodiment, a threaded hole 111 is opened on the outer periphery of the liquid inlet hole 11, and a connecting hole 211 is provided on the mounting ring 21, so that it is convenient to assemble the mounting ring 21 on the plate body 1, and extend its cylinder 22 into the liquid inlet hole 11, and by providing a partition 222 in the cylinder 22, a first liquid drain port 223 and a second liquid drain port 223 are opened on the partition 222, so that the waste liquid can enter the liquid guide channel 12 through the first liquid drain port 223 and the second liquid drain port 223, and finally be discharged outward through the liquid drain hole 13.

After the adjustment is completed, the plastic block 231 is deformed by the bending block 232, and the column 233 is engaged in the positioning hole 25 on the front side of the annular plate 241, thereby completing the limiting of the annular plate 241. The device is easy to operate, and since the plate body 1 can be disassembled and reused, the staff can manually adjust the aperture of the liquid inlet hole 11 before each use, thereby improving the practicality of the plate body 1.
