Description

Technical Field

[0001] The invention relates to a self-supporting steel chimney damper and belongs to the technical field of self-supporting steel chimneys. Background Art

[0002] Self-supporting steel chimney is a common building structure and an important industrial facility. It is mainly used to discharge waste gas and smoke in industrial processes to reduce pollution to the environment. It is mainly made of stainless steel, carbon steel or other high temperature and corrosion resistant materials, with stable structure, strong durability, easy installation, etc. Steel chimneys are widely used in power, chemical, metallurgical and other industries to discharge high temperature smoke and waste gas, and also play a role in protecting the environment and improving process flow.

[0003] For example, a Chinese patent with publication number CN218092352U discloses a self-supporting seismic steel chimney, including a chimney, a seismic base, a seismic reinforcement mechanism and a deformation detection mechanism; the seismic base is fixedly connected to the bottom of the chimney; the seismic reinforcement mechanism is fixedly connected to the top of the seismic connection seat; the deformation detection mechanism is fixedly connected to the left front side below the seismic connection seat. The present invention further strengthens the connection between the seismic isolation support and the chimney, increases the stability of the connection between the chimney and the seismic isolation support, facilitates the detection of the deformation of the seismic isolation support, facilitates the operation of the staff, and reduces the work intensity;

[0004] Self-supporting steel chimneys are widely used in civil buildings and industrial facilities. In civil buildings, self-supporting steel chimneys are mainly used to remove exhaust gas from kitchens and heating systems. In the industrial field, self-supporting steel chimneys are more common in large factories such as thermal power plants and steel mills to discharge large amounts of high-temperature flue gas. Chimney dampers are devices used to reduce or eliminate the vibration of chimneys under wind. Chimney dampers are usually installed on the outside of chimneys to absorb and disperse vibration energy, reduce the vibration amplitude of chimneys, and improve their stability and safety. The above patent is to reduce the vibration amplitude of chimneys when the anti-seismic base is deformed. At this time, the second detection block moves downward, and the surface scale of the second detection block changes. By recording the change of the surface scale of the second detection block, the deformation of the anti-seismic base can be detected. At the same time, by observing the offset angle of the connecting rope, the deformation angle of the anti-seismic base can be detected. However, during the use of the existing damper, springs and other components are usually exposed to the outside. When encountering bad weather such as rain, the damper is easily eroded by rain. Rain erosion may cause the performance of the damper material to deteriorate, such as strength reduction, weakened toughness, and even structural fracture. Chemical substances in rainwater, such as acidic substances in acid rain, will accelerate the corrosion process. In addition, rainwater penetration may also cause damage to the internal structure of the damper, affecting its normal operation and reducing the service life of the damper. At the same time, when the damper is partially damaged, it is not easy to disassemble it from the chimney. The damper will consume more time and energy during maintenance and repair, and may even be unable to be maintained in time due to the difficulty of disassembly, increasing the risk of accidents in the chimney.

[0005] To this end, a self-supporting steel chimney damper is proposed. Summary of the invention

[0037] By setting up the protection mechanism 2, through the cooperation of the sliding rod 203 and the sliding sleeve 204, the rain shield 206 can be moved to the outside of the damper body 5, and the damper body 5 can be protected by the rain shield 206, thereby reducing the degree of erosion of the damper body 5 by rainwater, increasing the service life of the damper body 5, and further increasing the stability of the chimney body 1.

The bottom of the mounting base 6 is provided with water outlet holes 7, and the water outlet holes 7 are evenly distributed at the bottom of the mounting base 6.

[0039] By setting the stabilizing mechanism 4, through the cooperation of the connecting rod 402, the second fixing block 403, the connecting block 404 and the fastening bolt 405, the fastening bolt 405 is screwed with a handheld tool, and the stabilizing plate 202 is connected and fixed through the cooperation of the fastening bolt 405 and the connecting block 404, so that the stabilizing plate 202 can reinforce and fix the chimney body 1, so as to achieve the effect of stabilizing the chimney body 1, and the stabilizing plate 202 can reinforce and fix the chimney body 1, so as to prevent the chimney body 1 from tilting when encountering strong wind blowing on the chimney body 1 for a long time, and the chimney body 1 can be reinforced and fixed to achieve the effect of stabilizing the chimney body 1.

By setting the water outlet hole 7, when there is too much rain, the rainwater will be discharged through the water outlet hole 7 opened at the bottom of the mounting base 6, so that the rainwater will no longer accumulate on the mounting base 6, thereby achieving the effect of drainage.

[0040] When the present invention is in operation, firstly, the fastening bolt 405 is tightened by a hand-held tool, and the fastening bolt 405 cooperates with the connecting block 404 to connect and fix the stabilizing plate 202, so that the stabilizing plate 202 reinforces and fixes the chimney body 1, thereby achieving the effect of stabilizing the chimney body 1;

[0041] Next, the positioning plate 301 connected to the outside of the damper body 5 is fitted with the support plate 201, and the mounting plate 208 connected to the inside of the damper body 5 is fitted with the stabilizing plate 202, and the first connecting plate 304 and the second connecting plate 305 are aligned, and the positioning bolt 302 is screwed with a hand tool, and the damper body 5 is installed through the connected positioning plate 301 and the support plate 201 through the cooperation of the positioning bolt 302 and the threaded hole 303, and then the connecting bolt 306 is screwed with a hand tool, so that the damper body 5 is installed through the cooperation of the first connecting plate 304 and the second connecting plate 305;

[0042] When the damper body 5 is installed, in order to reduce the degree of erosion of the damper body 5 by rain water, the rain shield 206 is manually pushed inward, so that the rain shield 206 drives the sliding sleeve 204 to slide on the surface of the sliding rod 203 through the connection with the support rod 205, so that the limiting rod 207 is aligned with the insertion limiting hole 209 and inserted into the inner cavity of the limiting hole 209, and the rain shield 206 is limited and fixed, so that the rain shield 206 is always located on the outside of the damper body 5. When rain falls, the damper body 5 is protected by the rain shield 206, the degree of erosion of the damper body 5 by rain water is reduced, the service life of the damper body 5 is increased, and the stability of the chimney body 1 is further increased. When there is too much rain, the rain water will be discharged through the water outlet 7 opened at the bottom of the installation base 6, so that the rain water will not accumulate on the installation base 6.

[0043] When it is necessary to disassemble the damper body 5, the hand-held tool is used to tighten the positioning bolt 302, and the positioning bolt 302 cooperates with the threaded hole 303 to make the damper body 5 detach from the support plate 201 through the connected positioning plate 301, and then the hand-held tool is used to tighten the connecting bolt 306 to separate the first connecting plate 304 from the second connecting plate 305, and the rain shield 206 is manually pushed outward so that the rain shield 206 drives the sliding sleeve 204 to slide outward on the surface of the sliding rod 203 through the connection with the support rod 205, so that the limiting rod 207 is separated from the inner cavity of the limiting hole 209, and the rain shield 206 is released from the limit, and then the damper body 5 is moved downward to remove the damper body 5, and the disassembly of the damper body 5 is completed, which facilitates the installation and disassembly of the damper body 5;

[0044] Through the cooperation of the connecting rod 402, the second fixing block 403, the connecting block 404 and the fastening bolts 405, the stabilizing plate 202 can be used to reinforce and fix the chimney body 1, thereby improving the stability of the chimney body 1. This can prevent the chimney body 1 from tilting when strong winds blow on the chimney body 1 for a long time. The chimney body 1 is reinforced and fixed to achieve the effect of stabilizing the chimney body. The damper body 5 is mainly used to reduce the vibration of the chimney body 1 caused by external forces such as wind and earthquake, to absorb and disperse vibration energy, reduce the vibration amplitude of the chimney body 1, and improve its stability and safety.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
