Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a conveniently detachable reheater. Background Art

[0002] The reheater is essentially a steam superheater that reheats the low-pressure steam that has done work to a certain temperature. In order to improve the thermal efficiency of the cycle of large-scale power generating units, the intermediate reheat cycle is widely used. The main steam from the existing boiler superheater is sent to the reheater for reheating to increase the temperature after doing work in the high-pressure cylinder of the steam turbine, and then sent to the intermediate-pressure cylinder of the steam turbine to continue to expand and do work. This is called an intermediate reheat cycle.

[0003] In the transportation process of existing reheater pipes, in order to avoid the phenomenon of stacking and colliding with each other, the reheater pipes are usually separated by partitions. However, although the use of existing partitions can avoid collision and damage between reheater pipes, it is not convenient to limit the position of the reheater pipes. Most of them use cross partitions to limit the outer wall of the pipe. Now, under the condition of ensuring the stability of the position between the cross partitions, screws or bolts and other fixings that need to be fastened with auxiliary tools are used to fasten the partitions. As a result, when the reheater is transported and needs to be used, auxiliary tools are required to remove the partitions before the reheater pipes can be removed. This method takes a long time, seriously affects the disassembly and assembly of the reheater position, and reduces the convenience and efficiency of disassembly and assembly of the reheater position. Therefore, in order to solve the above problems, a convenient disassembly and assembly reheater is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-5 A conveniently disassembled reheater is shown, comprising a reheater body 1 and a disassembly rack 2, wherein the disassembly rack 2 is fixedly arranged on the outer wall of the reheater body 1, and a limiting structure 3 is arranged between the disassembly rack 2 and the reheater body 1, wherein the limiting structure 3 comprises a limiting rod 301, a movable groove 302 and a positioning assembly, wherein the limiting rod 301 is movably arranged inside the disassembly rack 2 and located on the side of the reheater body 1, wherein the limiting rod 301 is used to fix the position of the reheater body 1 in the disassembly rack 2, wherein the movable groove 302 is provided at the top of the disassembly rack 2, wherein the movable groove 302 is used to provide a movable range of the limiting rod 301 in the disassembly rack 2, wherein the positioning assembly is arranged between the limiting rod 301 and the movable groove 302, wherein the positioning assembly is used to limit the position of the limiting rod 301 in the movable groove 302.

[0025] like Figure 1 , Figure 2 and Figure 3As shown in the figure, the reheater body 1 can avoid collision with the adjacent reheater body 1 during transportation through the disassembly and assembly rack 2, and the reheater body 1 can maintain a stable position in the disassembly and assembly rack 2 through the restriction of the limit rod 301. The number of the limit rods 301 is multiple, depending on the actual use requirements. The limit rods 301 move along the inner cavity of the movable groove 302, so that after the bent pipe part of the reheater body 1 is inside the disassembly and assembly rack 2, it can move to the side of the bent pipe, so that it can maintain a stable position under the squeezing of at least two limit rods 301, which provides convenience for the installation of the position of the reheater body 1. At the same time, when the reheater body 1 needs to be disassembled after transportation, it can also avoid too much twisting of auxiliary tools, etc., and the restriction on the reheater body 1 can be released by lifting and lateral movement of the position of the limit rod 301, which provides flexibility for the disassembly of the reheater body 1, thereby improving the convenience and efficiency of disassembly and assembly of the reheater body 1, and also enhancing the efficiency of transportation and use of the reheater body 1.

[0026] The disassembly and assembly frame 2 includes a bottom plate 201, a top plate 202 and a connecting plate 203. The connecting plate 203 is clamped at the ends of the bottom plate 201 and the top plate 202. The top plate 202 is arranged above the bottom plate 201. The top ends of the bottom plate 201 and the top plate 202 are both provided with movable grooves 302. A guide rod 303 is fixedly arranged in the inner cavity of one of the movable grooves 302. The two ends of the guide rod 303 respectively penetrate the two ends of the inner cavity of one of the movable grooves 302 and extend to the two ends of the bottom plate 201. A through hole is provided on the outer wall of the connecting plate 203. The through hole is used for the movable insertion of the guide rod 303. A fixing ring 4 is provided on the outer wall of the guide rod 303 and on one side of the connecting plate 203.

[0027] like Figure 2 and Figure 5As shown in the figure, the bottom plate 201 and the top plate 202 are respectively fixed to the bottom and top of the reheater body 1 by the connecting plate 203. The connecting plate 203 can be clamped and fixed with the ends of the bottom plate 201 and the top plate 202 by lateral extrusion. The number of the connecting plates 203 is at least two, which are used in conjunction with the two ends of the bottom plate 201 and the top plate 202. The connecting plate 203 is concave in shape, and can use its own shape to fix the bottom plate 201 and the top plate 202 in the upper and lower positions. At the same time, the bottom plate 201 and the top plate 202 can be disassembled separately, so that they can be used in combination according to the needs of the reheater body 1, and further, when the disassembly frame 2 itself is not in use, it can reduce the space occupied and improve the convenience of storage. The inner cavity of the movable groove 302 opened at the top of the top plate 202 is connected to the bottom end of the top plate 202, and the guide rod 303 The setting of the guide rod 303 and the limit rod 301 enables the limit rod 301 to be indirectly connected to the base plate 201, and can prevent the limit rod 301 from falling off from the inner cavity of one of the movable grooves 302 when moving, thereby ensuring the effectiveness of the use of the limit rod 301. Furthermore, after extending to the two ends of the base plate 201, the two ends of the limit rod 301 are movably interlaced with the outer wall of the connecting plate 203, and then the position is restricted by the fixing ring 4. The fixing ring 4 is threadedly interlaced with the outer wall of the guide rod 303, and the fixing ring 4 is rotated along the outer wall of the guide rod 303. On the basis of ensuring that the guide rod 303 is stationary, the rotating fixing ring 4 and the outer wall of the connecting plate 203 are squeezed. In this way, the position of the guide rod 303 can be kept stable, and the stability of the position of the connecting plate 203 can also be enhanced.

[0028] The positioning assembly includes a symmetrical positioning block 304 and a plurality of positioning grooves 305 . The plurality of positioning grooves 305 are evenly spaced on both sides of the inner wall of the movable groove 302 . The positioning block 304 is fixedly disposed on the outer wall at the top end of the limiting rod 301 . The positioning block 304 is engaged with the inner cavity of the positioning groove 305 .

[0029] like Figure 2 and Figure 3 As shown in the figure, the positioning block 304 is fixedly connected to the limit rod 301 and will move with the movement of the position of the limit rod 301. The inner cavity of the positioning groove 305 is connected with the inner cavity of another movable groove 302. The positioning grooves 305 are arranged at equal intervals so that the positioning block 304 can be engaged with the corresponding positioning groove 305 when it moves to different positions. Therefore, when the limit rod 301 moves, it can move along the inner cavity of the movable groove 302 by lifting the position, and after moving, it can drive the positioning block 304 to engage with the positioning groove 305 at the corresponding position by pressing the position. Therefore, the position of the limit rod 301 can be limited, and then the effectiveness of the limit rod 301 in limiting the position of the reheater body 1 can be ensured.

[0030] The limiting rod 301 includes a first rod body 3011 , a second rod body 3012 and a spring 3013 . The spring 3013 is fixedly disposed between the first rod body 3011 and the second rod body 3012 . The first rod body 3011 is movably sleeved on the outer wall of the second rod body 3012 .

[0031] like Figure 4 As shown in the figure, the first rod body 3011 is movably sleeved on the top end of the second rod body 3012, and the connection with the spring 3013 allows the first rod body 3011 and the second rod body 3012 to slide while avoiding falling off. When the limiting rod 301 needs to move, the first rod body 3011 can be lifted upward to drive the positioning block 304 to move upward, so that the positioning block 304 is separated from the corresponding positioning groove 305, thereby releasing the restriction on the position of the limiting rod 301 and allowing the limiting rod 301 to move. After the movement, the lifting force on the first rod body 3011 can be released to make the first rod body 3011 drop under the rebound energy of the spring 3013, thereby driving the positioning block 304 to engage with the corresponding positioning groove 305 below, thereby limiting the position of the limiting rod 301, and further ensuring the stability and effectiveness of the limiting rod 301 on the reheater body 1.
