▎ 摘　　要

NOVELTY - The device has a stainless steel kettle structure that is composed of an exhaust valve (1), a quick opening clamp (3), a support (5), a kettle structure upper seal (8), a sealing ring (9), a high-pressure glass (10), a sealing assembly (11), a high-pressure glass pressing plate (12) and a kettle structure lower seal (13). The data monitoring system includes pressure sensor (2), first temperature sensor (6) and the second temperature sensor (7). The two heating plates (4) are detachable and installed symmetrically on both sides of the stainless steel kettle structure. The exhaust valve is installed on the kettle structure upper seal that is detachable above the stainless steel kettle structure. The bottom seal of the kettle structure is located under the graphene hydrogel preparation kettle structure and is not removed. The quick opening clip is used to lock the top seal of the kettle structure to ensure the airtightness of the stainless steel kettle structure. USE - Device for preparing graphene hydrogel. ADVANTAGE - The preparation device has good monitoring effect on the preparation of graphene hydrogel, the device is simple and easy to operate, the data is easy to obtain and the maintenance cost is low. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the device for preparing graphene hydrogel.
