Detailed description of the invention
Below embodiments of the invention are described in detail:
As shown in Figures 3 to 6, a kind of rotary drum pulping machine, comprise barrel tumbler body 10 and feed hopper 20, barrel tumbler body 10 is provided with charging aperture 11, feed hopper 20 is arranged on this charging aperture 11 place, and the feeding-passage 21 of feed hopper 20 leads to described charging aperture 11, realize being tightly connected by labyrinth seal structure between described barrel tumbler body 10 and described feed hopper 20.
Wherein, above-mentioned labyrinth seal structure comprises seal ring seat 30 and an annular double wedge 40, seal ring seat 30 is connected with above-mentioned feed hopper 20 by bolt, annular double wedge 40 is arranged on above-mentioned barrel tumbler body 10, and seal ring seat 30 and annular double wedge 40 are all arranged around the central axis of above-mentioned charging aperture 11.Sealing ring seat 30 is provided with a closure gasket groove 31 matched with annular double wedge 40, in annular double wedge 40 embedding sealing annular groove 31, and has activity space between annular double wedge 40 and closure gasket groove 31.Above-mentioned annular double wedge 40 comprises main teeth portion 41 and hook part 42, and hook part 42 is arranged in described main teeth portion 41, and hook part 42 is positioned at closure gasket groove 31.Certainly, above-mentioned seal ring seat 30 also can be connected with barrel tumbler body 10, and correspondingly, above-mentioned annular double wedge 40 is arranged on feed hopper 20; And closure gasket groove 31 also can be set to two or more, accordingly, the quantity of annular double wedge 40 can be consistent with the quantity of closure gasket groove 31, and each annular double wedge 40 embeds in corresponding closure gasket groove 31 respectively.
