PURPOSE:To seal surely, by dividing a vessel to be freely joinable and separable in vertical direction, and providing bearing bodies in a protruding state to both end walls of the upper half body, and forming a seal flange at the peripheral part of the lower half body except the bearing bodies. CONSTITUTION:A vessel 2 of a mixer A is divided into an upper half body and a lower half body, and further, a driving and separating means capable of separating and joining the upper and lower half bodies 7 and 8 is provided to the mixer A. The body 7 is formed into a rectangular opening part 4 by an opening-periphery frame 9, and bearing supporting bodies 10 as bearing bodies 57 are attached to both side ends of the frame 9. The body 8 is fixed to side- end-plates 25 at the lengthwise both side-ends of a bottom plate 24 formed into a U-shape, and U-shaped notched surfaces 27 are formed in the plates 25. A sealing flange 30 abutting upon the lower surface of the frame 9 is formed at the periphery of the body 8 except the notch 27. And a packing is pressed into the flange 30 to enhance a sealing performance. |
