Description

Technical Field

[0001] This utility model relates to superheaters, and more specifically, to a screen-type superheater for a waste incinerator. Background Technology

[0002] A screen-type superheater, also known as a semi-radiative superheater, is a heating surface located at the top of the furnace or at the furnace outlet flue, which receives both direct radiative heat from the furnace and convective heat from the flue gas.

[0003] Currently, most screen-type superheaters have a fixed structure and poor flexibility. When the superheater tubes are damaged after long-term use, the staff cannot quickly replace them. Some superheaters are installed quickly using motors or other drives, but because the installation location of the superheater is at a high temperature, the drive is prone to damage in the high-temperature environment for a long time. Therefore, there is an urgent need to improve this. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a screen-type superheater for a waste incinerator. The movable part is fixed to the second fixed plate by a nut. By turning the nut, the movable part can be manually moved, thereby separating the fixed plate and the movable plate, which facilitates the replacement of the superheater tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screen-type superheater for a waste incinerator, comprising a first fixed plate, a second fixed plate, a fixed clamping plate, and a movable component. The first fixed plate and the second fixed plate are fixedly connected. The movable component includes a movable clamping plate. The fixed clamping plate and the movable clamping plate are located between the first fixed plate and the second fixed plate. The fixed clamping plate is fixedly connected to the first fixed plate, and the movable clamping plate is movably connected to the second fixed plate. The movable clamping plate can move closer to or further away from the fixed clamping plate.

[0006] Furthermore, the movable component also includes a connecting frame, which is fixedly connected to the movable clamping plate, and the connecting frame is fixedly connected to the second fixed plate by a nut.

[0007] Furthermore, the connecting frame includes a horizontal plate located outside the second fixed plate. Connecting arms are provided at both ends of the horizontal plate, and connecting ribs are provided at the ends of the connecting arms. The connecting ribs pass through the second fixed plate and their protruding ends are fixedly connected to the movable clamping plate. A screw is provided on the side of the second fixed plate away from the first fixed plate. The screw passes through the horizontal plate and its protruding end is threaded with a nut.

[0008] Furthermore, the connecting arm and the horizontal plate form an I-shaped structure, the connecting rib is located at both ends of the connecting arm, and the second fixing plate includes a clearance hole corresponding to the connecting rib. The connecting rib passes through the clearance hole, and the size of the clearance hole is larger than the cross-sectional size of the connecting rib.

[0009] Furthermore, connecting posts are fixed to the inner wall of the first fixed plate near the four corners. The connecting posts pass through the fixed clamping plate and the movable clamping plate respectively. The movable clamping plate can move along the connecting posts. The other end of the connecting posts abuts against the second fixed plate and is fixedly connected to the second fixed plate.

[0010] Furthermore, the fixed clamping plate includes two first clamping sections arranged vertically, with the two ends of the two first clamping sections connected by a first connecting section, and the connecting post passing through the first connecting section. The movable clamping plate includes a second clamping section corresponding to the first clamping section, with the two ends of the second clamping section connected by a second connecting section, and the connecting post passing through the second connecting section.

[0011] Furthermore, the inner wall of the first fixing plate is provided with a plurality of support columns, which abut against the side of the fixing clamp and are fixedly connected to the fixing clamp.

[0012] Furthermore, the inner wall of the first fixing plate is provided with multiple hooks near the top.

[0013] Furthermore, the lower parts of the first fixing plate and the lower parts of the second fixing plate are fixedly connected by a base plate, and the upper part of the base plate is provided with multiple U-shaped pieces.

[0014] In summary, this utility model has the following beneficial effects:

[0015] When replacing the superheater tube, loosen the nuts connecting the horizontal plate and the second fixed plate. Pulling the horizontal plate moves the movable clamping plate away from the fixed clamping plate. When the distance between the movable and fixed clamping plates is greater than the superheater tube diameter, simply pull the superheater tube upwards to remove it from between the fixed and movable clamping plates. When installing the superheater tube, insert it from top to bottom between the fixed and movable clamping plates, pre-fixing it to the fixed clamping plate. Once the superheater tube is in place, tightening the nut at the screw will move the movable clamping plate to engage with the fixed clamping plate, clamping the superheater tube. This method allows for superheater tube replacement without the need for a driver, offering convenient operation and high reliability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this embodiment discloses a screen-type superheater for a waste incinerator, including a first fixed plate 1, a second fixed plate 2, a fixed clamping plate 3, and a movable part 100. The first fixed plate 1 and the second fixed plate 2 are fixedly connected. A connecting column 11 is fixed to the inner wall of the first fixed plate 1 near the four corners. The other end of the connecting column 11 abuts against the second fixed plate 2 and is fixedly connected to the second fixed plate 2. The connecting column 11 is welded to the first fixed plate 1 and is fixedly connected to the second fixed plate 2 by bolts.

[0024] The movable component 100 includes a movable clamping plate 4. The fixed clamping plate 3 and the movable clamping plate 4 are located between the first fixed plate 1 and the second fixed plate 2. The superheating pipe 8 is fixed between the fixed clamping plate 3 and the movable clamping plate 4. The fixed clamping plate 3 is fixedly connected to the first fixed plate 1, and the movable clamping plate 4 is movably connected to the second fixed plate 2. The movable clamping plate 4 can move closer to or away from the fixed clamping plate 3. Specifically, the connecting column 11 passes through the fixed clamping plate 3 and the movable clamping plate 4 respectively, and the movable clamping plate 4 can move along the connecting column 11. The movable component 100 also includes a connecting frame 5. The connecting frame 5 is fixedly connected to the movable clamping plate 4 and fixedly connected to the second fixed plate 2 by a nut. The connecting frame 5 includes a horizontal plate 51, which is located on the second fixed plate. 2. Externally, the horizontal plate 51 is provided with connecting arms 52 at both ends, and the connecting arms 52 are provided with connecting ribs 53 at their ends. The connecting ribs 53 pass through the second fixed plate 2 and are fixedly connected to the movable clamping plate 4 at their protruding ends. The second fixed plate 2 is provided with a screw 22 on the side away from the first fixed plate 1. The screw 22 passes through the horizontal plate 51 and is threadedly connected to a nut at its protruding end. The fixed clamping plate 3 includes two first clamping sections 31 arranged vertically. The two ends of the two first clamping sections 31 are respectively connected by a first connecting section 32. The connecting post 11 passes through the first connecting section 32. The movable clamping plate 4 includes a second clamping section 41 corresponding to the first clamping section 31. The two ends of the second clamping section 41 are respectively connected by a second connecting section 42. The connecting post 11 passes through the second connecting section 42.

[0025] When the superheater tube 8 needs to be replaced, loosen the nuts connecting the horizontal plate 51 and the second fixed plate 2. At this time, the horizontal plate 51 can be pulled to move, which in turn drives the movable clamping plate 4 to move away from the fixed clamping plate 3. When the distance between the movable clamping plate 4 and the fixed clamping plate 3 is greater than the diameter of the superheater tube 8, simply pull the superheater tube 8 upward to remove it from between the fixed clamping plate 3 and the movable clamping plate 4. When the superheater tube 8 needs to be installed, insert the superheater tube 8 from top to bottom between the fixed clamping plate 3 and the movable clamping plate 4, and pre-fix the superheater tube 8 to the fixed clamping plate 3. After the superheater tube 8 is in place, by tightening the nut at the screw 22, the movable clamping plate 4 can be moved to cooperate with the fixed clamping plate 3 to achieve the clamping operation of the superheater tube 8. The superheater tube 8 can be replaced without the need for a driver, which is convenient and reliable.

[0026] The length of the superheater tube 8 is less than the distance between the two connecting posts 11 in the length direction. The two ends of the superheater tube 8 are connected to external pipes. The external pipes can pass through the first fixing plate 1 and the second fixing plate 2 and connect to the superheater tube 8. Before replacing the superheater tube 8, the pipes at both ends of the superheater tube 8 need to be disconnected from the superheater tube 8.

[0027] like Figure 1 and Figure 5The connecting arm 52 and the horizontal plate 51 form an I-shaped structure. The connecting ribs 53 are located at both ends of the connecting arm 52, and there are four connecting ribs 53. By setting it into this structure, the structural strength of the connecting frame 5 and the connection strength between the connecting frame 5 and the movable clamping plate 4 can be effectively improved, thereby improving the reliability of fixing the superheated pipe 8.

[0028] The second fixing plate 2 includes a clearance hole 21 corresponding to the connecting rib 53. The connecting rib 53 passes through the clearance hole 21. The size of the clearance hole 21 is larger than the cross-sectional size of the connecting rib 53. By setting the clearance hole 21, the assembly of the connecting frame 5 and the movable clamping plate 4 can be facilitated.

[0029] like Figure 4 As shown, the inner wall of the first fixing plate 1 is provided with a plurality of support columns 12. The support columns 12 abut against the side of the fixing clamp 3 and are fixedly connected to the fixing clamp 3. By setting the support columns 12, the fixing clamp 3 can be suspended and connected to the first fixing plate 1.

[0030] like Figure 3 and Figure 4 As shown, the inner wall of the first fixing plate 1 is provided with multiple hooks 7 near the top. The lower part of the first fixing plate 1 and the lower part of the second fixing plate 2 are fixedly connected by a base plate 6. The upper part of the base plate 6 is provided with multiple U-shaped pieces 61. The superheating pipe 8 includes a vertical section 81 and bent sections 82 at the upper and lower ends of the vertical section 81. The vertical section 81 is clamped and fixed by a fixing clamp 3 and a movable clamp 4. The bent section 82 located above is suspended on the hooks 7, and the bent section 82 located below is inserted into the U-shaped pieces 61. By setting the hooks 7 and U-shaped pieces 61, the superheating pipe 8 can be pre-fixed to the fixing clamp 3, thereby facilitating the clamping and fixing of the superheating pipe 8.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected.
