Description

Technical Field

[0001] This utility model relates to a drying device, specifically a drying device for anion exchange membranes. Background Technology

[0002] Anion exchange membranes have a wide range of applications, serving as crucial components in separation devices, purification systems, and electrochemical modules. They play a vital role in the chlor-alkali industry, water treatment, heavy metal recovery, hydrometallurgy, and electrochemical industry. In recent years, with the development of new chemical power sources, the application of anion exchange membranes as battery separators in flow batteries, alkaline anion exchange membrane fuel cells, and novel supercapacitors has also attracted attention and research. To increase the membrane surface area and improve its performance, organic solvent evaporation is often used to create a porous structure on the membrane surface. This can be achieved using impregnation or casting methods. After initial membrane formation, drying is necessary to evaporate excess organic solvent from the membrane surface, thus forming a porous structure. This drying process requires thorough and uniform drying of the membrane, necessitating a flat and evenly laid-out anion exchange membrane to prevent pore collapse, lack of density, or uneven distribution.

[0003] Chinese patent discloses a drying device for anion exchange membranes (authorization announcement number CN 221425290 U). This patented technology can dry the exchange membrane; however, the structure uses clamps to hold the membrane, and this small-area fixation method may cause the membrane to tear and detach during rotation. Furthermore, uneven heating at the edges can lead to wrinkles. Additionally, the hot airflow is not fully utilized; it is simply used as a heating method, failing to fully leverage the airflow's potential. Therefore, those skilled in the art have provided a drying device for anion exchange membranes to address the problems mentioned in the background art. Utility Model Content

When the pressing plate is released, the spring retracts and pulls the pressing plate closer to the mounting platform, so that the exchange membrane is pressed against the contact pads on the upper and lower sides by the pressing plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model adopts a fully enclosed clamping method, which can avoid localized addition that could cause the exchange membrane to rupture, and can also make the exchange membrane heat up more evenly so as not to cause wrinkles.

[0011] 2. This utility model utilizes the heating conditions brought by the hot airflow and the effect of the airflow on evaporation. By using a fan and hydraulic rod, the exchange membrane is simultaneously subjected to drying and blowing effects, enabling the exchange membrane to dry faster. Attached Figure Description
