Embodiment Construction

[0018] In order to make the content of the present invention more obvious and understandable, the present invention will be described in detail below in conjunction with specific embodiments.

[0019] As shown in the figure, a composite rotary kiln sealing device includes a packing 3 wound around the connection between the rotary cylinder 1 and the outer wall 2 of the cover, and the upper end surface and the outer end surface of the packing 3 respectively pass through the sealing seat The ring I4 and the sealing seat ring Ⅱ5 are pressed tightly. A pressing plate I6 is arranged between the sealing seat ring I4 and the upper end surface of the packing 3, and an arc-shaped leaf spring I7 is arranged in the annular cavity between the pressing plate I6 and the sealing seat ring I4. The middle part of the leaf spring I7 is fixed on the sealing seat ring I4, the two ends of the leaf spring I7 are pressed on the pressure plate I6; the sealing seat ring II5 is pressed against the outer end...

Abstract

The invention discloses a composite rotary kiln sealing device. The composite rotary kiln sealing device comprises a packing arranged at the joint position of a rotary barrel and the outer wall of a cover in a winding manner. The upper end face of the packing is pressed through a sealing race I, and the outer end face of the packing is pressed through a sealing race II. A pressing plate I is arranged between the sealing race I and the upper end face of the packing. A plate spring I of an arc structure is arranged in an annular cavity between the pressing plate I and the sealing race I. The middle portion of the plate spring I is fixed to the sealing race I, and the two ends of the plate spring I are pressed on the pressing plate I. The sealing race II presses the outer end face of the packing through the side wall connected by one side, a gland is arranged on the other side of the sealing race II, and a rubber sealing ring is arranged in an annular cavity between the side wall of the sealing race II and the gland. A pressing plate II is arranged on the rubber sealing ring in a pressed manner. An arc plate spring II is arranged in an annular cavity between the pressing plate II and the sealing race II. The composite rotary kiln sealing device is high in air tightness, capable of adapting to barrel roundness and radial run-out of a rotary kiln, safe and reliable, and long-term efficient running of the device can be guaranteed.

Description

Technical field [0001] The invention belongs to the field of industrial equipment such as building materials, metallurgy, chemical industry, non-ferrous metals, etc., and specifically relates to a composite rotary kiln sealing device. Background technique [0002] The sealing device of rotary kiln equipment is used to seal between the outer cylindrical surface of the rotary cylinder and the fixed cover. At present, there are many kinds of sealing devices used in this type of industry. Commonly used are spring steel sheet type seal and end face friction type. Sealed, labyrinth seal. The spring steel sheet seal can effectively compensate for the radial runout of the rotary kiln shell, but there is a gap between the spring sheet and the barrel, and there is a gap between the spring sheets, and the gas leakage in the kiln is inevitable under a certain pressure. Therefore, it can only be used for rotary kilns that do not require high air tightness. End face friction seal. Due to the...
