Description
Technical Field
[0001] The invention relates to a particle damper for a chimney, belonging to the technical field of dampers. Background Art
[0002] Vibration control is one of the main contents of tall structure calculation. The existing more effective vibration control method is to set tuned mass damper (TMD) or tuned liquid damper (TLD) in the area with large structural vibration amplitude to reduce the structural vibration response. Its working mechanism is to design the damper's natural frequency to be close to the main structure frequency, and achieve the purpose of dynamic vibration reduction through the reverse resonance between the damper and the main structure. Among them, there are particle dampers suitable for chimneys. The particle damper of the chimney is a device used to control chimney vibration and reduce noise. It is usually composed of a container filled with granular materials (such as sand or pebbles), and the interaction of particles is used to absorb vibration energy.
[0003] For example, a Chinese patent with publication number CN220704818U discloses a particle damper for a chimney, comprising a chimney body, a damper shell fixedly installed under the signal light platform at the top of the chimney body, filling particles arranged inside the damper shell, and a plurality of unit partitions arranged inside the damper shell; the particle damper for a chimney provided by the present invention is installed under the signal light platform at the top of the chimney, has a simple structure, convenient construction, high reliability, long service life, good anti-aging and corrosion resistance, can adapt to extremely harsh conditions, avoids the shortcomings of TLD elements, and the cost of the filling particles in the cavity is much lower than the damping liquid in TLD; compared with TMD, it avoids the use of a simple hoisting form to connect the mass block, avoids the risk of the mass block falling during use, and is safer; in addition, it expands the application scenarios of particle dampers in the field of civil engineering, and provides a model for the subsequent research and application of particle dampers;
[0004] The damper in the above device is assembled as an integral part. When the particle damper is installed, its large size and weight make the overall installation inconvenient. At the same time, when the particles inside the damper are worn for a long time, the particles in the separate partition cannot be removed and replaced. Moreover, since the particle damper is installed in the chimney, the chimney will discharge a large amount of heat during operation. This heat may be conducted to the damper, causing the particles inside to be heated and deformed, thereby deteriorating the overall damping effect of the damper.
[0005] Therefore, a particle damper for a chimney is proposed. Summary of the invention

[0011] Further preferably, screw grooves are provided on both the upper and lower sides of the damping box, and the fixing bolts are threadedly connected in the inner cavity of the screw grooves.
[0012] Further preferably, the outside of the cooling box is provided with a heat dissipation groove, the three semiconductor refrigeration blocks are clamped in the inner cavity of the three heat dissipation grooves, and the heat dissipation ends of the three semiconductor refrigeration blocks pass through the inner cavity of the heat dissipation groove and extend to the outside of the cooling box.
[0013] Further preferably, a support plate is clamped on the surface of the air inlet pipe, and the bottom of the support plate is fixedly mounted on the top of the damping box.
[0014] Further preferably, an air inlet hole is provided at the bottom of the cooling box, and filters are fixedly installed in the inner cavities of the air inlet hole and the air outlet groove.
[0015] Further preferably, a reinforcement mechanism is provided on the surface of the damping box, the reinforcement mechanism includes a polyurethane thermal insulation layer, the polyurethane thermal insulation layer is fixedly installed in the inner cavity of the damping box, the outer surface of the damping box is sprayed with an epoxy resin corrosion-resistant coating, and the side of the epoxy resin corrosion-resistant coating away from the damping box is sprayed with a chromium carbide wear-resistant coating.

[0018] Further preferably, the front sides of the five damping boxes are provided with reserved grooves, and the size of the reserved grooves matches the size of the straight ladder.
[0019] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:
[0020] First, the present invention sets a splicing mechanism. After a plurality of damping boxes are close to and fitted to each other, the I-shaped block is clamped into the inner cavity of the notch, and then the fixing bolt is rotated to complete the fixation of the I-shaped block and the damping box. The splicing work of the damping box can be completed by fixing the I-shaped block. Compared with the one-piece damper, this method can facilitate the disassembly of a separate damping box, and facilitate the replacement and maintenance of the damping particles in the damping box of a separate area, avoiding the need to disassemble the entire body to complete the replacement of the damping particles after the damping particles in a certain area are worn out due to long-term use, thereby improving the convenience of the damping box installation and facilitating the operator. The staff can use it by setting a cooling mechanism, and the semiconductor refrigeration block works. At this time, the cooling box draws cold air into the air inlet pipe, and enters the inner cavity of the damping box through the conduction of the air inlet pipe. By cooling the temperature in the inner cavity of the damping box, it can effectively avoid that when the damping box and the damping particles are on the outside of the chimney body, due to the high temperature of the chimney body when working, the temperature is conducted to the inner cavity of the damping box, causing the damping particles to deform, and the overall damping effect of the damping particles to deteriorate. The loss caused by the temperature influence is reduced, the stability of the damping particles during operation is improved, and the service life of the damping particles in the equipment is extended.
[0021] Second, the present invention can facilitate the disassembly of the fixing bolts by providing the screw grooves, thereby improving the convenience and stability of the overall splicing of the damping box. By providing the heat dissipation grooves, it can be prevented that the heat generated by the semiconductor refrigeration block during operation is accumulated in the inner cavity of the cooling box, thereby affecting the temperature reduction work in the inner cavity of the damping box. By providing the support plate, the air inlet pipe can be supported to prevent the air inlet pipe from falling off after long-term use, thereby affecting the delivery of cold air. By providing the filter screen, the air outlet groove and the inner cavity of the cooling box can be filtered to prevent dust from entering the air outlet groove and the inner cavity of the cooling box and causing pollution to the internal components. A reinforcing mechanism is provided, and through the cooperation of the polyurethane insulation layer, the epoxy resin corrosion-resistant coating and the chromium carbide wear-resistant coating, the damping box has the characteristics of wear resistance, corrosion resistance and heat insulation, and the overall strength of the damping box is improved, thereby extending the service life of the damping box. By providing a breathable box and a desiccant, the humidity in the inner cavity of the damping box can be dehumidified to avoid the damping effect of the damping particles being affected by humidity. By providing the damping box, since the shape of the inner side is arc-shaped, the entire damping box can be tightly clamped to the outside of the chimney body. By providing a reserved groove, it is convenient to reserve installation space for the straight ladder, which provides convenience for the installation of the straight ladder.

DETAILED DESCRIPTION
[0033] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, an embodiment of the present invention provides a particle damper for a chimney, comprising a chimney body 1, a straight ladder 5 is fixedly installed on the front side of the outer surface of the chimney body 1, a damping box 6 is fixedly installed on the top of the outer surface of the chimney body 1, the inner cavity of the damping box 6 is filled with damping particles 7, and an air outlet groove 8 is opened at the bottom of the damping box 6;
[0036] The surfaces of the five damping boxes 6 are all provided with a splicing mechanism 2, and the splicing mechanism 2 includes a notch 201. The four notches 201 are all opened on the upper and lower sides of the surface of the damping box 6. An I-shaped block 202 is clamped in the inner cavity of the notch 201. The outer side of the I-shaped block 202 is fixedly installed with a gasket 203. The surfaces of the two gaskets 203 are threadedly connected with fixing bolts 204. The two notches 201 are spliced into an I-shape, and the dimensions of the inner cavities of the two notches 201 match the dimensions of the I-shaped block 202. Screw grooves 205 are opened on the upper and lower sides of the damping box 6, and the fixing bolts 204 are threadedly connected in the inner cavity of the screw grooves 205.
[0037] By setting up the splicing mechanism 2, after multiple damping boxes 6 are close to and fit together, the I-shaped block 202 is clamped into the inner cavity of the slot 201, and then the fixing bolt 204 is rotated to complete the fixation of the I-shaped block 202 and the damping box 6. The splicing of the damping box 6 can be completed by fixing the I-shaped block 202. Compared with the one-piece damper, this method can facilitate the disassembly of a separate damping box 6, and facilitate the replacement and maintenance of the damping particles 7 in the damping box 6 of a separate area, so as to avoid the damping particles 7 in a certain area being worn out after long-term use, and the need to disassemble the entire body to complete the replacement of the damping particles 7, thereby improving the convenience of installation of the damping box 6 and facilitating the use of the operator. By setting the screw groove 205, the fixing bolt 204 can be easily disassembled, thereby improving the convenience and stability of the overall splicing of the damping box 6.
[0038] like Figure 4 , Figure 5 and Figure 7 As shown, in one embodiment, the surfaces of the five damping boxes 6 are all provided with cooling mechanisms 3, and the cooling mechanisms 3 include cooling boxes 301, and the cooling boxes 301 are fixedly installed on the outside of the damping boxes 6, and the top of the cooling boxes 301 is fixedly installed with a fan 302, and the output end of the fan 302 is connected to an air inlet pipe 303, and the end of the air inlet pipe 303 away from the fan 302 is connected to the inner cavity of the damping box 6, and the inner cavity of the cooling boxes 301 is provided with a semiconductor refrigeration block 304, and the outer side of the cooling boxes 301 is open. A heat dissipation groove 305 is provided, and three semiconductor refrigeration blocks 304 are all clamped in the inner cavity of the three heat dissipation grooves 305. The heat dissipation ends of the three semiconductor refrigeration blocks 304 all penetrate the inner cavity of the heat dissipation groove 305 and extend to the outside of the cooling box 301. A support plate 308 is clamped on the surface of the air inlet pipe 303, and the bottom of the support plate 308 is fixedly installed on the top of the damping box 6. An air inlet hole 306 is opened at the bottom of the cooling box 301, and a filter screen 307 is fixedly installed in the air inlet hole 306 and the inner cavity of the air outlet groove 8.
[0039] By setting the cooling mechanism 3, the semiconductor refrigeration block 304 performs refrigeration work, and the cooling box 301 draws cold air into the air inlet pipe 303, and enters the inner cavity of the damping box 6 through the conduction of the air inlet pipe 303. By cooling the temperature in the inner cavity of the damping box 6, it can effectively avoid that when the damping box 6 and the damping particles 7 are outside the chimney body 1, due to the excessive temperature of the chimney body 1 during operation, the temperature is conducted to the inner cavity of the damping box 6, causing the damping particles 7 to deform, thereby making the overall damping effect of the damping particles 7 worse. The loss caused by the temperature influence is reduced, the stability of the damping particles 7 during operation is improved, and the operation time is prolonged. In order to extend the service life of the damping particles 7 in the equipment, by setting the heat dissipation groove 305, it is possible to prevent the heat generated by the semiconductor refrigeration block 304 during operation from accumulating in the inner cavity of the cooling box 301, thereby affecting the temperature reduction work in the inner cavity of the damping box 6. By setting the support plate 308, the air inlet pipe 303 can be supported to prevent the air inlet pipe 303 from falling off after long-term use, thereby affecting the delivery of cold air. By setting the filter 307, the air outlet groove 8 and the inner cavity of the cooling box 301 can be filtered to prevent dust from entering the air outlet groove 8 and the inner cavity of the cooling box 301 and causing pollution to the internal components.
[0040] like Figure 1 , Figure 2 and Figure 8 As shown, in one embodiment, a reinforcing mechanism 4 is provided on the surface of the damping box 6, and the reinforcing mechanism 4 includes a polyurethane insulation layer 401, and the polyurethane insulation layer 401 is fixedly installed in the inner cavity of the damping box 6, and the outer surface of the damping box 6 is sprayed with an epoxy resin corrosion-resistant coating 402, and the side of the epoxy resin corrosion-resistant coating 402 away from the damping box 6 is sprayed with a chromium carbide wear-resistant coating 403, and a breathable box 404 is fixedly installed on the side of the polyurethane insulation layer 401 away from the damping box 6, and a desiccant 405 is fixedly installed in the inner cavity of the breathable box 404, the inner sides of the five damping boxes 6 are all arc-shaped, and the sizes of the inner sides of the five damping boxes 6 match the sizes of the chimney body 1, and the front sides of the five damping boxes 6 are provided with reserved grooves 9, and the sizes of the reserved grooves 9 match the sizes of the straight ladder 5.
[0041] By setting up the reinforcing mechanism 4, through the cooperation of the polyurethane insulation layer 401, the epoxy resin corrosion-resistant coating 402 and the chromium carbide wear-resistant coating 403, the damping box 6 has the characteristics of wear resistance, corrosion resistance and heat insulation, and the overall strength of the damping box 6 is improved, thereby extending the service life of the damping box 6. By setting up the breathable box 404 and the desiccant 405, the humidity in the inner cavity of the damping box 6 can be dehumidified to avoid the damping effect of the damping particles 7 being affected by humidity. By setting up the damping box 6, since the shape of the inner side is arc-shaped, the damping box 6 as a whole can be tightly connected to the outer side of the chimney body 1. By setting up the reserved groove 9, it is convenient to reserve installation space for the straight ladder 5, providing convenience for the installation of the straight ladder 5.
[0042] When the present invention is working: firstly, multiple damping boxes 6 are spliced together, and the inner side of the damping box 6 is made to fit the outer side of the chimney body 1. At this time, the notches 201 are combined into an I-shape, and the I-shaped block 202 is clamped in the inner cavity of the notch 201. At this time, the gasket 203 fits the upper and lower sides of the damping box 6, and then the fixing bolts 204 are screwed and connected to the inner cavity of the screw groove 205, thereby completing the splicing of the damping box 6. Then, the temperature in the inner cavity of the cooling box 301 is cooled by the operation of the semiconductor refrigeration block 304. At this time, the input end of the fan 302 generates suction and draws the cold air in the inner cavity of the cooling box 301. Then, the fan 30 2 injects air into the air inlet pipe 303, and through the conduction of the air inlet pipe 303, the cold air enters the inner cavity of the damping box 6, completing the cooling work of the damping particles 7, and through the cooperation of the polyurethane insulation layer 401, the epoxy resin corrosion-resistant coating 402, and the chromium carbide wear-resistant coating 403, the overall strength of the damping box 6 is improved, so that it has the characteristics of wear resistance, corrosion resistance and heat insulation, thereby extending the service life of the damping box 6. When the humidity of the environment in which the equipment is running is too high, after the moisture enters the damping box 6, the moisture entering the damping box 6 is absorbed by the characteristics of the desiccant 405 material, which can dehumidify the damping particles 7.
[0043] 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.
