Abstract

The invention discloses a universal rotary dynamic sealing device and gyration equipment. The dynamic sealing device comprises a dynamic ring and a static ring, wherein the dynamic ring is fixed on a rotating part and makes gyration movement together with the rotating part; the static ring is connected with a static part through a universal rod, and the sealing surface of the static ring is attached to the sealing surface of the dynamic ring; the universal rod is composed of a bulb component and a threaded rod, the bulb end is connected with the static part, the threaded rod is connected with the static ring, springs and clamp nuts are installed on the universal rod, and the springs are tightly pressed on the static ring by the clamp nuts. The dynamic sealing device disclosed by the invention can effectively solve the problem of seal failure caused by radial runout of the rotating part and axial movement caused by thermal expansion, and has the characteristics of good sealing effect and, high-temperature resistance and the like.

Description

technical field

[0001] The invention relates to a dynamic sealing device, which is suitable for the sealing between the rotary cylinder and the fixing device of rotary equipment, and can be used for sealing gas, liquid and solid, especially for high temperature medium, and also relates to a rotary equipment, the rotating The joint of the cylinder body and the fixing device is provided with the universal rotary dynamic sealing device. Background technique

[0002] Rotary equipment, such as rotary cylinder dryer, is widely used in metallurgy, petrochemical industry, environmental protection building materials and other fields. There are inevitably gaps at the joints between the rotating cylinder and parts and fixtures. In order to prevent external air from being sucked into the cylinder or to prevent If the medium in the cylinder leaks and pollutes the environment, dynamic sealing devices must be installed at these parts.

[0003] With the rapid development of the chemical in...
