Description

Technical Field

[0001] The utility model relates to the technical field of chimneys, in particular to a chimney provided with a solid-liquid hybrid damper with a partition. Background Art

[0002] The existing chimney damper is a pure liquid damper, which is used to reduce the vibration of the chimney when the chimney vibrates. However, when it is used, the amount of liquid used is large and the efficiency is low: the damping effect of the traditional pure liquid damper is mainly achieved by the viscosity and friction of the liquid. The amount of liquid used is large, and due to the fluidity of the liquid, the damping efficiency is low, and large-amplitude vibrations cannot be effectively controlled; the single-group damping is small, and multiple groups need to be set up for synergy: since the single-group damping of the liquid damper is small, in order to achieve the desired damping effect, it is usually necessary to set up multiple groups of dampers for synergy, which increases the installation cost and maintenance difficulty; the participating mass coefficient is small: the participating mass coefficient of the liquid in the traditional pure liquid damper is relatively small, and it cannot provide sufficient mass and inertia, which limits the stability and suppression effect of the damper. Utility Model Content

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a chimney provided with a solid-liquid hybrid damper with a partition. Through the interaction between the damping liquid and the solid spheres, a greater damping effect is provided, the vibration amplitude can be more effectively reduced, and the vibration suppression effect is improved. The solid-liquid structure composed of the damping liquid and the solid spheres is more stable. The presence of the solid spheres can increase the mass of the damper, making it more stable and reliable, and suitable for vibration control with a larger amplitude and frequency range. In addition, the space between the liquid and the solid sphere can be separated by a partition with a through hole. The through hole allows the liquid to flow between the cavities, which can better adapt to the control requirements of vibrations of different frequencies and has a wider range of applications than traditional pure liquid dampers.

[0004] The utility model also provides a chimney with the above-mentioned solid-liquid hybrid damper with a partition, comprising: a chimney body, the outer wall of the chimney body is fixedly connected to the damper shell, the damper shell is provided with a cavity, the inner surface of the cavity is fixedly connected to the partition, the partition is provided with a through hole, the inner surface of the cavity is movably connected to a solid ball, and the inner surface of the cavity is provided with damping liquid.

[0021] The outer wall of the chimney body 4 is fixedly connected to the damper shell 5, and a cavity 10 is arranged on the damper shell 5 for providing space for the solid ball 16 and the damping liquid 13. The inner surface of the cavity 10 is fixedly connected to the partition 15 for separating the space between the damping liquid 13 and the solid ball 16. The partition 15 is provided with a through hole 14 so that the damping liquid 13 can flow between the cavities 10. The inner surface of the cavity 10 is movably connected to the solid ball 16. The inner surface of the cavity 10 is provided with the damping liquid 13. The solid ball 16 will interact with the damping liquid 13 to increase the damping effect and reduce the vibration amplitude.
