Description

Technical Field

[0001] The utility model relates to the technical field of superheater protection, in particular to an anti-wear structure for changing a screen-type superheater. Background Art

[0002] A superheater is a component in a boiler that further heats steam from saturation temperature to superheat temperature, also known as a steam superheater. Superheaters can be divided into convection, radiation and semi-radiation types according to the heat transfer method; they can be divided into serpentine tube type, screen type, wall type and wall-wrapped type according to the structural characteristics. They are all composed of several parallel tubes and inlet and outlet headers. Most industrial boilers are not equipped with superheaters because many industrial production processes and living facilities only require saturated steam. In power stations, locomotives and marine boilers, superheaters are generally installed to improve the cycle thermal efficiency of the entire steam power unit. During the use of the existing new screen superheater, when the hot air flows through, it is easy to bring impurities. The impurities impact the pipeline body, which is easy to cause damage to the pipeline body and shorten the service life of the screen superheater. For this reason, we propose a wear-resistant structure that changes the screen superheater. Utility Model Content

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figure 1-5As shown, the utility model is a wear-proof structure for changing a platen superheater, comprising a pipe body 1, the outer surface of the pipe body 1 is coated with an anti-rust coating 14, the anti-rust coating 14 is a graphene modified coating, due to the characteristics of the graphene modified coating, the wear resistance and corrosion resistance of the superheater pipe body 1 can be improved, and at the same time, due to the thermal conductivity of the graphene modified coating, the temperature difference between the two ends of the pipe body 1 can be reduced, thereby ensuring the service life of the pipe body 1 itself

[0021] The outside of the pipe body 1 is fittedly connected to the telescopic rod 21, and a shock-absorbing spring 22 is sleeved on the outside of the telescopic rod 21. The bottom of the telescopic rod 21 is connected to the sleeve 2. One end of the shock-absorbing spring 22 is connected to the outer wall of the pipe body 1, and the other end is connected to the inner wall of the sleeve 2. A buffer structure is formed between the telescopic rod 21 and the shock-absorbing spring 22. When the pipe body 1 is installed and fixed, the pipe body 1 and the telescopic rod 21 are installed at the ends. When the pipe body 1 is shaken by external impact, the telescopic rod 21 and the shock-absorbing spring 22 can absorb the impact force, thereby achieving the shock-absorbing effect of the pipe body 1 and extending the service life of the pipe body 1.

[0022] A connecting rod 11 is provided on the outside of the sleeve 2, and mounting plates 12 are provided at both ends of the connecting rod 11. The sleeves 2 are fixed to each other through the connecting rod 11. A first bolt 13 is provided on the mounting plate 12, and the mounting plate 12 is installed and fixed by the first bolt 13. When the screen type superheater is installed and used, the mounting plates 12 on both sides are placed at the required installation positions, and the mounting plates 12 are fixed and installed by the first bolt 13. The connecting rods 11 arranged above and below complete the installation of the pipeline body 1.

[0023] A protective pad 31 is provided on the outside of the pipe body 1. The protective pad 31 is a flexible graphite pad as a whole. The inner end of the flexible graphite pad is in contact with the pipe body 1. The protective pad 31 is fixed to the inner side of the anti-wear plate 3. When the pipe body 1 and the anti-wear plate 3 expand due to heat, the protective pad 31 provided therebetween will be squeezed, and the protective pad 31 will be deformed due to the force. When not in use, the protective pad 31 will restore itself to its original shape due to its own resilience, so that a gap can be left for the thermal expansion of the pipe body 1 and the anti-wear plate 3, thereby ensuring the safety of the overall use.

[0024] An anti-wear plate 3 is provided on the outside of the protection pad 31, and a protrusion 32 is provided on the surface of one side of the anti-wear plate 3, and a clamp 33 is provided on the other side of the anti-wear plate 3. By fixing the anti-wear plate 3 on the outside of the pipeline, the protrusions 32 are equidistantly distributed on one side of the anti-wear plate 3, and multiple protrusions 32 are horizontally and vertically. The provided protrusions 32 can first contact the dust particles in the hot air, and can initially resist the impact force to prevent the anti-wear plate 3 from being worn by foreign particles during the long-term operation of the anti-wear plate 3. If there is dust between the protrusions 32, it is convenient to use a brush or other tools to clean in one direction according to the gap between the protrusions 32, which saves cleaning time and is convenient for later workers to clean.

[0025] In the above scheme, the clamp 33 is provided with a second bolt 34, and the anti-wear plate 3 is provided with a mounting hole matching the second bolt 34. The clamp 33 is connected and installed with the anti-wear plate 3 through the second bolt 34. When installing the anti-wear plate 3, the anti-wear plate 3 is installed at the hot air inlet end of the pipe body 1, the clamp 33 is wrapped around the other side of the pipe body 1, and the second bolt 34 is inserted into the mounting hole on the anti-wear plate 3 for fixed installation.

[0026] Working principle:

[0027] The anti-wear structure of the platen superheater is changed. When working, the platen superheater is installed at a desired position by means of the mounting plate 12 and the first bolt 13. During use, the provided protrusions 32 and the anti-wear plate 3 can resist impurities mixed in the hot gas, thereby preventing the impurities from impacting the pipeline and causing serious wear of the pipeline. In addition, when the pipeline body 1 shakes during use, the provided shock-absorbing spring 22 and the telescopic rod 21 can buffer the impact force, thereby further improving the service life of the pipeline body 1.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
