Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Example 1, see FIGS. 1-3:

the embodiment provides a roller rail type supporting kiln tail sealing device, which is the same as the prior art in that a fixed kiln tail cover is arranged at the tail part of a rotary kiln, an annular movable supporting plate 1 is movably arranged on the kiln tail cover, and the movable supporting plate 1 is in dynamic sealing connection with a rotary kiln cylinder 2 through a friction ring 13. After the rotary kiln cylinder 2 jumps, the movable supporting plate 1 is driven to move, so that the friction ring 13 is tightly attached to the rotary kiln cylinder 2.

Wherein, the movable supporting plate 1 is annular and the peripheral surface is fixedly provided with a supporting convex plate 3 which extends in an outward scattering shape. The supporting convex plate 3 can be used for movably connecting the kiln tail cover. In order to enhance the axial movement fluency of the whole sealing structure, linear rails 4 are arranged on the left side and the right side of the kiln tail cover along the axial direction of the rotary kiln barrel 2. And in order to adapt to the field processing environment, the linear track 4 comprises a pair of C-shaped channel steels 7, and the concave surfaces of the C-shaped channel steels 7 are opposite and are arranged separately. Thus, a chute with a lower side groove opening is formed, a sliding part 5 is arranged in the chute in a rolling way, and a suspender 6 connected with the movable supporting plate 1 is arranged below the sliding part 5. Therefore, the moving fluency of the movable supporting plate 1 when the rotary kiln barrel 2 axially jumps can be improved.

In this embodiment, the sliding part 5 includes a pulley shaft 8 and a pair of pulleys 9, the pulley shaft 8 is horizontally disposed, the two pulleys 9 are respectively installed at the left and right ends of the pulley shaft 8 and respectively roll in the concave surface of the C-shaped channel steel 7, and the structures and forms of the sliding part 5 and the linear rail 4 are convenient for installation and can be used for a long time in a site environment with large dust.

In order to improve the smoothness of the radial runout of the rotary kiln barrel 2, a hanger rod 6 is hinged with a sliding piece 5 and a supporting convex plate 3. The upper end and the lower end of the suspender 6 are respectively hinged with the middle part of the pulley shaft 8 and the supporting convex plate 3 through fisheye bearings 10, and the fisheye bearings 10 have a large moving range, so that the rotary kiln can adapt to the movement of the rotary kiln barrel 2. Therefore, when the rotary kiln cylinder 2 makes radial run-out, the movable support plate 1 can also move easily.

In the above structure, the hinge shafts hinged to the two fisheye bearings 10 are arranged in parallel in the static state of the rotary kiln cylinder 2. It can also be seen that for the installation of the device, in order to make the linear rail 4 uniformly stressed, the two side booms 6 should be stressed in the optimal state in the same way, which requires that the two articulated supporting flanges 3 on the left and right sides are arranged as symmetrically as possible. The boom 6 thus has a telescopic function for better adjustment and mounting of the mobile support plate 1. Specifically, the hanger rod 6 includes two connecting sections 11 and one adjusting section 12, two the lower part and the upper portion of connecting section 11 are provided with the internal thread respectively, adjusting section 12 is stud, and it is two respectively the spiro union the internal thread of connecting section 11. In this way, the length of the suspension rod 6 can be finely adjusted by screwing, and the adjustment mode is simple and reliable.

At the rotary kiln operation in-process, rotary kiln barrel 2 can produce radial and axial and beat, and friction ring 13 plays the sealed effect of laminating to rotary kiln barrel 2 simultaneously, and this just makes under rotary kiln barrel 2's thrust effect, and movable support plate 1 can be very light back and forth movement under jib 6 supports to the dead circumstances of card does not appear, and then improves sealed effect.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, it should be understood that those skilled in the art should also understand the scope of the present invention without inventively designing the similar structure and embodiments of the present invention without departing from the spirit of the present invention.
