Description

Technical Field

[0001] The utility model relates to the technical field of pipeline supports, and specifically relates to an anti - dust - accumulation soot blower pipeline support and suspension structure. Background Technique

[0002] As an important part of the soot blower system, the soot blower pipeline is responsible for transporting the purging medium (such as compressed air, steam, etc.) to the position that needs to be cleaned.

[0003] During the working process, the soot blower pipeline will experience alternating high and low temperatures. This temperature change causes the pipeline material to thermally expand and contract. Since the soot blower pipeline is usually long and the distance between the fixed points is large, the thermal expansion and contraction will generate different displacements in different parts of the pipeline, thus forming a displacement difference. This displacement difference will cause thermal stress inside the pipeline, and in the long run, it may lead to pipeline deformation, leakage, or even damage. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti - dust - accumulation soot blower pipeline support and suspension structure to solve the problem that the displacement difference mentioned in the above background technique will cause thermal stress inside the pipeline, and in the long run, it may lead to pipeline deformation, leakage, or even damage.

A chute is opened inside the pipeline body, and guide rails are symmetrically distributed on the inner surface of the guiding bearing. The front and rear ends of the guide rails are in an inclined structure, and the inclined ends of the guide rails extend towards the outer wall of the guiding bearing. The guide rails are slidably matched with the chute, and the guiding bearing is movably connected with the guiding support.

[0006] As a preferred technical solution of the content of the utility model, one end of the connecting column is provided with a rubber shock - absorbing block, and the rubber shock - absorbing block is in a fitting connection with the inner wall of the ear plate.

[0007] As a preferred technical solution of the content of the utility model, a damper is arranged inside the suspension bracket, and a compression spring is arranged between the damper and the rubber shock - absorbing block.

[0008] As a preferred technical solution of the content of the utility model, connecting plates are symmetrically arranged on the outer surface of the guiding support, and an arc - shaped scraper is movably installed at one end of the connecting plate.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: an anti - ash - accumulation soot - blower pipeline suspension structure, including a suspension bracket 1 and a guiding support 2. A connecting column 4 is slidably connected between the guiding support 2 and the suspension bracket 1. A guiding bearing 8 is arranged inside the guiding support 2, and a pipeline body 10 is movably connected inside the guiding bearing 8. A chute 11 is opened inside the pipeline body 10. Guide rails 9 are symmetrically distributed on the inner surface of the guiding bearing 8. The front and rear ends of the guide rails 9 are in an inclined structure, and the inclined ends of the guide rails 9 extend towards the outer wall of the guiding bearing 8. The guide rails 9 are slidably matched with the chute 11, and the guiding bearing 8 is movably connected with the guiding support 2.

[0019] One end of the connecting column 4 is provided with a rubber shock absorber 5. The rubber shock absorber 5 is in a fitting connection with the inner wall of the ear plate 3. In the normal state, the rubber shock absorber 5 is in contact with the top end of the inner wall of the ear plate 3 through the elastic supporting force of the compression spring 7, and can use the elastic structure to absorb the vibration that may occur during the operation of the soot - blower pipeline, avoiding fatigue damage or loosening of the connection of the pipeline.

[0020] A damper 6 is provided inside the suspension bracket 1, and a compression spring 7 is provided between the damper 6 and the rubber shock-absorbing block 5. The rubber shock-absorbing block 5 has good elasticity and temperature resistance and can absorb large displacements and impacts. The compression spring 7 can provide a certain elasticity and control displacement. The damper 6 provides a certain damping effect to reduce the vibration of the system.

[0021] A connecting plate 12 is symmetrically provided on the outer surface of the guide support 2, and an arc-shaped scraper 13 is movably installed at one end of the connecting plate 12. The arc-shaped scraper 13 is made of elastic material, and the front and rear ends of the arc-shaped scraper 13 are arc-shaped structures to avoid being inserted into the chute 11 of the pipeline during friction with the pipeline. At the same time, the arc-shaped scraper 13 and the guide support 2 constitute a movable disassembly and assembly structure, which is convenient for subsequent maintenance and replacement.

[0022] The angle between the arc scraper 13 and the connecting end of the pipe body 10 is acute. The arc scraper 13 and the pipe body 10 are slidably matched. The arc scraper 13 is placed at an angle, which effectively increases the contact area with the pipe and can remove floating dust on the surface of the pipe by scraping. An ear plate 3 is provided at the top of the suspension bracket 1.

[0023] Working principle: The suspension bracket 1 is fixedly installed in a designated fixed position through the ear plate 3. The slide groove 11 of the pipe body 10 corresponds to the guide rail 9 of the guide bearing 8 and is horizontally connected in a plug-in manner. The guide bearing 8 is movably connected to the guide support 2, so that the pipe body 10 can move axially, allowing the sootblower and the sootblowing pipe to move freely during thermal expansion to reduce damage caused by thermal stress. At the same time, it can also move horizontally to adapt to the displacement caused by thermal expansion. The tapered part of the guide rail 9 can also use the moving action to remove dirt in the slide groove 11. Under normal conditions, the rubber shock absorber block 5 is in contact with the top of the inner wall of the ear plate 3 through the elastic support force of the compression spring 7. The elastic structure can absorb the vibration that may be generated by the sootblower pipe during operation to avoid fatigue damage or loose connection of the pipe. The curved scraper 13 is made of elastic material, and the front and rear ends of the curved scraper 13 are curved structures to avoid being inserted into the slide groove 11 of the pipe during friction with the pipe. At the same time, the curved scraper 13 and the guide support 2 constitute a movable disassembly structure, which is convenient for subsequent maintenance and replacement.
