[0033] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0034] like Figure 1 、 Figure 2The structure of the utility model shown is a boiler vibration-proof structure, and the boiler includes a boiler body steel structure 4 and a water-cooled wall body steel structure 5; on the side of the boiler body steel structure 4, a boiler body vibration-proof channel steel 1 is provided and fixed vertically to the side of the boiler body steel structure 4 as a whole.

[0035] In order to solve the problems existing in the prior art and overcome its defects, and to achieve the invention purpose of improving the stability of the boiler and preventing the boiler from being damaged due to vibration, the technical solution adopted by the utility model is as follows:

[0036] like Figure 2 As shown, the boiler seismic isolation structure of the present invention is provided with a water-cooled wall seismic isolation channel steel 3 fixedly connected to the water-cooled wall body steel structure 5 at a position corresponding to the boiler body seismic isolation channel steel 1 on the water-cooled wall body steel structure 5, and the water-cooled wall seismic isolation channel steel 3 is sleeved on the boiler body seismic isolation channel steel 1.

[0037] The water-cooled wall anti-seismic channel steel 3 is welded to the boiler body steel structure 4; the water-cooled wall anti-seismic channel steel 3 is welded to the water-cooled wall body steel structure 5; the boiler body anti-seismic channel steel 1 and the water-cooled wall anti-seismic channel steel 3 are not welded, so that they have a certain room for relative movement, but can prevent their relatively large movement, so as to reduce and overcome the impact of vibration.

[0038] When disasters such as earthquakes and explosions occur, the water-cooled wall seismic isolation channel steel 3 will shake together with the water-cooled wall 6, but the boiler body seismic isolation channel steel 1 will prevent the water-cooled wall seismic isolation channel steel 3 from shaking. Conversely, the water-cooled wall seismic isolation channel steel 3 will also prevent the boiler body seismic isolation channel steel 1 from shaking, thereby reducing the impact of vibration.

[0039] The water-cooled wall anti-vibration channel steel 3 and the boiler body anti-vibration channel steel 1 are clearance-fitted.

[0040] The clearance fit enables the water-cooled wall anti-vibration channel steel 3 and the boiler body anti-vibration channel steel 1 to have a certain relative micro-movement, reducing the rigid transmission of vibration, and playing a certain collision damping role, achieving the purpose of anti-vibration, anti-vibration and anti-vibration.

[0041] The gap between the water-cooled wall anti-vibration channel steel 3 and the boiler body anti-vibration channel steel 1 in all directions is 3 mm.

[0042] A gap of 3mm can just stop vibrations in general industrial boilers. If the gap is too large, it cannot stop vibrations; if the gap is too small, it cannot absorb the energy of vibrations, nor can it prevent or reduce vibrations.

[0043] The boiler body steel structure 4 is hung on the steel structure beam on the top of the boiler.

[0044] The boiler body steel is suspended on the top steel structure beam, which also plays a role of flexible shock absorption to a certain extent, allowing it to swing to a certain extent, which has a good shock absorption effect.

[0045] The boiler anti-vibration structure is provided with boiler reinforcing channel steels 2 symmetrically distributed with the boiler body anti-vibration channel steel 1. The two ends of the boiler reinforcing channel steel 2 are respectively fixedly connected to the side of the boiler body steel structure 4 and the boiler body anti-vibration channel steel 1. The boiler reinforcing channel steel 2, the side of the boiler body steel structure 4 and the boiler body anti-vibration channel steel 1 form a triangle.

[0046] The boiler body anti-vibration channel steel 1 and the boiler reinforcement channel steel 2 are welded into a whole, which improves the stability of the overall structure and the firmness of the connection.

[0047] The triangular reinforcement structure is adopted and the stability of the triangle is utilized to further improve the firmness and stability of the connection between the boiler body anti-seismic channel steel 1 and the boiler body.

[0048] The boiler body anti-vibration channel steel 1 passes through the water-cooled wall anti-vibration channel steel 3 to form a freely retractable structure.

[0049] This design will not hinder the thermal expansion of the boiler. During boiler production, expansion and contraction are inevitable due to the high temperature and large amount of heat. It is necessary to allow room for expansion and contraction, otherwise huge thermal pressure internal stress will be generated within the structure, causing deformation or even damage.

[0050] like Figure 1 As shown:

[0051] On the side of each of the boiler body steel structures 4 , a water-cooled wall anti-vibration channel steel 3 and corresponding water-cooled wall anti-vibration channel steel 3 are provided.

[0052] Since the direction of vibration is random, such as earthquakes, which have both longitudinal and transverse waves, a shockproof structure should be adopted in all directions. Therefore, a shockproof structure needs to be provided on the sides of the boiler body steel structure 4.

[0053] A water-cooled wall 6 is provided on the water-cooled wall main body steel structure 5 , and a water cooling pipeline is fixedly arranged on the water-cooled wall 6 ; the water-cooled wall 6 is fixedly connected to the water-cooled wall main body steel structure 5 via a water-cooled wall fixing support 7 .

[0054] The water-cooled wall 6 is fixed on the water-cooled wall body steel structure 5, and then the water cooling pipeline is installed and fixed. Therefore, the water-cooled wall body steel structure 5 is used for shock protection and vibration reduction. The water cooling pipeline is not easily damaged, and is not prone to leakage, blockage and other problems, which can well protect the water cooling pipeline.

[0055] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
