Problems solved by technology
However, because the linear expansion coefficient of graphite is lower than that of steel parts, under the action of temperature, it is easy to cause phenomena such as expansion and cracking of outsourced graphite, so that new stirring shafts need to be replaced continuously, thereby reducing the service life of the stirring shaft , also reduces work efficiency

The invention discloses an agitating mechanism for a graphite reaction kettle. The agitating mechanism comprises a spindle steel pipe, a spindle graphite pipe is arranged on the outer surface of the spindle steel pipe which is connected with a plurality of agitating blades in symmetrical arrangement, and each agitating blade is in a circular structure formed by an agitating blade center shaft, an agitating blade steel pipe and an agitating blade center shaft end plate. An agitating blade graphite pipe is arranged on the outer surface of each agitating blade steel pipe, an agitating blade graphite plug is arranged on the outer side of each agitating blade center shaft end plate, each agitating blade graphite pipe and the corresponding agitating blade graphite plug form a square agitating blade graphite protection structure, and a spindle graphite plug is arranged at the bottom of the spindle steel pipe. By modification of original agitating blades, steel elements and graphite structures are modified in consideration of the fact that coefficient of linear expansion of graphite is smaller than that of the steel elements, and accordingly the problem of proneness to bursting of external wrapping graphite is solved, and service lives of products are prolonged.
Description
Technical field [0001] The invention relates to a stirring mechanism, in particular to a stirring mechanism applied in a large graphite reactor. Background technique [0002] The stirring mechanism is one of the core components of the graphite reactor. The general stirring mechanism consists of a main shaft and various stirring shafts, and the outer surface of the stirring shaft is made of graphite coated steel pipe (the structure is as attached figure 2 Shown). However, because the linear expansion coefficient of graphite is lower than that of steel parts, under the action of temperature, it is easy to cause phenomenon such as expansion and cracking of outer graphite, which requires constant replacement of new stirring shafts, thereby reducing the service life of the stirring shaft , It also reduces work efficiency. Summary of the invention [0003] Objective of the invention: The objective of the present invention is to solve the deficiencies in the prior art and provide a gra...
