Abstract
Description
Technical Field
[0001] The utility model relates to a device for aligning the whole row of boiler tube screens. Background Art
[0002] A boiler is a device that uses the heat energy released by fuel combustion to heat the working medium to a certain parameter. The boiler tube screen pipes are in the harsh environment of high temperature, high pressure inside the boiler and being blown by flue gas. The tube screens are blown and damaged by the high-temperature flue gas, resulting in the aggravation of pipe thinning. Since the boiler tube screen pipes are not on the same horizontal line, the tube screens swing back and forth in the boiler for a long time, resulting in collision and friction between adjacent tube screens. To sum up, a device for aligning the whole row of boiler tube screens is needed to solve the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to solve the problem that the boiler tube screen pipes are not on the same horizontal line, resulting in mutual friction of the pipes in the boiler and the aggravation of pipe thinning, which is not conducive to flue gas circulation, and provides a device for aligning the whole row of boiler tube screen pipes.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A device for aligning the whole row of boiler tube screens, which comprises boiler tube screen pipes. Tube screen connection blocks are welded between adjacent two pipes of the boiler tube screen pipes. A steel groove fixing plate A is movably installed above the boiler tube screen pipes, and a steel groove fixing plate B is movably installed below. There is a set of adjusting holes A and a set of adjusting holes B on both the steel groove fixing plate A and the steel groove fixing plate B. The steel groove fixing plate A and the steel groove fixing plate B are fixed by passing fixing screws and locking nuts through the adjusting holes.
[0006] In the device for aligning the whole row of boiler tube screens, the tube screen connection blocks are divided into tube screen connection block A and tube screen connection block B. The tube screen connection block A is welded to the adjacent boiler tube screen pipe on the left side, and the tube screen connection block B is welded to the adjacent boiler tube screen pipe on the right side. Advantageous Effects
[0007] 1. The utility model reduces the back-and-forth swing of the boiler tube screen pipes in the boiler and the collision and friction with adjacent tube screen pipes, and quickly and effectively makes the tube screen pipes on the same horizontal line, which is helpful for the normal circulation of flue gas.
[0008] 2. The design of the tube screen connection blocks in the utility model facilitates the sliding of the tube row pipes, leaving a tiny gap in the static state, and eliminates the thermal expansion of the pipes in the high-temperature and high-pressure environment inside the boiler during the operation of the unit. Description of the Drawings
[0009] Attached Figure 1 is the front view of the utility model;
[0010] Appendix Figure 2 is the left view of the present utility model;
[0011] Appendix Figure 3 is the front view of the tube screen connection block of the present utility model in a static environment;
[0012] Appendix Figure 4 is the front view of the tube screen connection block of the present utility model in a hot environment.

[0014] Referring to Figures 1 - 2 , a device for the whole row of boiler tube screens, which comprises a boiler tube screen pipeline 9. Tube screen connection blocks are welded between adjacent pipelines of the boiler tube screen pipeline. A steel channel fixing plate A 1 is movably connected above the boiler tube screen pipeline and the tube screen connection block, and a steel channel fixing plate B 2 is movably installed below. There is a set of adjusting holes A 5 and a set of adjusting holes B 6 on both the steel channel fixing plate A and the steel channel fixing plate B. The steel channel fixing plate A and the steel channel fixing plate B are fixed by using a fixed screw 3 and a locking nut 4 to penetrate the adjusting holes.
[0015] Referring to Figures 3 - 4 , in the device for the whole row of boiler tube screens, the tube screen connection blocks are divided into a tube screen connection block A 7 and a tube screen connection block B 8. The tube screen connection block A is welded to the adjacent boiler tube screen pipeline on the left side, and the tube screen connection block B is welded to the adjacent boiler tube screen pipeline on the right side. There is a gap between the tube screen connection block A and the tube screen connection block B in the static environment, and the tube screen connection block A coincides with the tube screen connection block B in the hot environment of the boiler.
[0016] Working principle:
[0017] Because the boiler tube screen pipelines are not on the same horizontal plane in actual use and the tube screen pipelines are uneven, place the steel channel fixing plate B under the tube screen pipelines, place the tube screen connection blocks between adjacent tube screen pipelines, place the steel channel fixing plate A above the tube screen pipelines and the tube screen connection blocks, use a set of fixing bolts to penetrate the adjusting holes, and then use a set of locking nuts for fixation. After installation, weld the tube screen pipelines and the adjacent tube screen connection blocks into a whole. After all the work is completed, remove the steel channel fixing plate, and then carry out the whole row work of the next row of tube screen pipelines.
