Embodiment Construction
[0031] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0032] Such as Figure 1 to Figure 3 As shown, an inner and outer heat medium circulating heating spinning assembly for preparing mesophase pitch-based carbon fibers, including a heat medium circulating heating chamber 1, a raw material inlet plate 2, a mixing porous plate 3, a spinneret plate 4, and an inner layer fixing sleeve 5. The outer fixed sleeve 6, the sealing gasket 7, the first edging filter screen 8, and the second edging filter screen 9.
[0033] The raw material inlet plate 2 is fixed on the upper inner cavity of the heat medium circulation heating cavity 1 through threads, and the sealing gasket 7 is between the raw material entrance plate 2 and the heat medium circulation heating cavity 1 . The mixing perforated plate 3 is installed from the bottom of the heat medium circulation heating cavity 1 to the top of the lower inner chamber, and the first edg...
