A Pilot Reactor for Preparation of Expanded Graphite Based on Microwave Method

Abstract

The invention discloses a pilot plant test reactor for preparing expanded graphite based on a microwave method. The reactor comprises a bracket. A box body is connected to the upper side of the bracket, a plurality of microwave sources are arranged on the inner side wall of the box body, a feeder is arranged on the upper left side of the box body, a tray is arranged on the lower side of the feeder, warpping rods are fixedly connected to two sides of the left end of the tray, side rods are fixedly connected to two sides of the box body, screws are rotatably connected in the side bars, a first screw block and a second screw block are in engaged connection to each screw, the upper end of the first screw block is rotatably connected to the right end of each warpping rod, the upper end of the second screw block is rotatably connected to a supporting rod, and the end, far away from the second screw block, of the supporting rod is rotatably connected to the middle of each warpping rod. The reactor can heat and expand expandable graphite by microwave to prepare the expanded graphite. Materials are dialed to the tray uniformly by means of a dialing column, and a swing brush swings back andforth to uniformly pave and brush the materials again, so that the paving thickness of the expanded graphite can be more uniform and the graphite is expanded more thoroughly.

Description

technical field [0001] The invention relates to the technical field of microwave preparation of expanded graphite, in particular to a pilot-scale reactor for preparing expanded graphite based on a microwave method. Background technique [0002] Expanded graphite, also known as flexible graphite (EG for short), is a new type of functional carbon material. Worm-like substance. The expanded graphite is in the shape of a worm. Many tiny pores are formed on the surface and inside of the expanded graphite worm, and the specific surface area is greatly increased. It is a good adsorption material and has been widely used and studied. At present, the preparation method of expanded graphite is mainly realized by heating the expandable graphite to 1000 degrees Celsius. In the traditional technology, the high-temperature expansion method is usually used to prepare expanded graphite. High consumption; with the development of microwave technology, more people use microwave method to exp...

Problems solved by technology

At present, the preparation method of expanded graphite is mainly realized by heating the expandable graphite to 1000 degrees Celsius. In the traditional technology, the high-temperature expansion method is usually used to prepare expanded graphite. High consumption; with the development of microwave technology, more people use microwave method to expand expandable graphite. Compared with traditional high-temperature expansion method, microwave method is convenient to start and stop, and has the advantages of high efficiency and energy saving In the preparation process, the uneven thickness of the expandable graphite is prone to incomplete local expansion; and the existing preparation has a low degree of automation and a lot of manual participation. Therefore, we propose a microwave-based method. Pilot reactor for the preparation of expanded graphite
