Feeding and discharging device for graphite high-temperature purification furnace

Abstract

The present invention relates to a feeding and discharging device for graphite high-temperature purification furnace. The device includes a heating furnace body (1), a feed bin (5) and a discharge bin(6). The heating furnace body (1) comprises a furnace tube (2), an induction coil (3) and a shell (4). The induction coil (3) is wound along the outer wall of the furnace tube (2). One side, withoutthe induction coil(3), in the furnace tube (2) is provided with a graphite boat (9), and one side of the graphite boat (9) is connected with a push rod (10) which is connected with an external mechanical pushing device. The upper side of one side of the furnace tube (2) is connected with the feed bin (5) and the lower side is connected with the discharge bin (6). The bottom of the feed bin (5) isprovided with a feeding valve (7) and the top of the discharge bin (6) is provided with a discharging valve (8). The advantages of the feeding and discharging device for the graphite high-temperaturepurification furnace comprise thatfeeding and discharging are integrated, the design length of the high-temperature purification furnace is shortened, cooling of the graphite boat is avoided, the production efficiency is improved and the energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of high-temperature purification furnace equipment, in particular to a material feeding and discharging device for a graphite high-temperature purification furnace. Background technique [0002] Graphite high-temperature purification furnace is mainly used for high-temperature treatment such as graphite powder purification, which is an important research and development direction of high-purity graphite production process. At present, the continuous high-temperature purification furnace has a variety of structures and types, generally including a heating furnace body, a feeding pipe and a discharging pipe, but the design of the feeding and discharging part is too long, which increases the heat loss in the production process and increases the production cost. At the same time, the difficulty of production design is increased due to the large occupied area. Therefore, it is necessary to improve the inlet and ...
