Description

Technical Field

[0001] This utility model belongs to the field of grid protection technology, specifically a heat-conducting grid flow stabilization and anti-wear device for circulating fluidized bed boilers. Background Technology

[0002] Circulating fluidized bed combustion technology is a clean coal combustion technology highly recognized by the market. It boasts advantages such as high efficiency, low pollution, strong adaptability to different coal types, and good load controllability. During boiler operation, impurities such as coal ash, unreacted limestone, and limestone desulfurization reaction products are rapidly fluidized under the influence of the boiler's airflow and combustion heat, forming a high-speed particle stream. Larger particles at different heights in the furnace fall along the furnace walls, forming a wall-attached flow. This descent of the wall-attached flow erodes the water-cooled walls, causing severe wear on the membrane wall's heating surface. To address this membrane wall wear problem, anti-wear devices are added to the membrane wall to control the gas-solid flow velocity within the furnace and reduce furnace wall wear. Existing anti-wear devices typically use bolts for installation and fixation. Disassembly and assembly require aligning the bolts and using tools to rotate them, making the anti-wear layer installation and disassembly complex and resulting in low maintenance efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a heat-conducting grid flow stabilization and anti-wear device for circulating fluidized bed boilers. It solves the problem that the anti-wear device is usually installed and fixed with bolts, and the installation and disassembly process requires aligning the bolts and rotating the bolts with tools. The disassembly and assembly of the anti-wear layer is relatively complicated, resulting in low maintenance efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat-conducting grid flow stabilization and anti-wear device for a circulating fluidized bed boiler, comprising a water-cooled wall, several mounting seats fixedly connected to one side of the water-cooled wall, with the mounting seats arranged in pairs facing each other; fixed plates symmetrically fixedly connected to the upper and lower sides of the mounting seats; two fixed rods symmetrically fixedly connected inside the fixed plates; the same plug-in block slidably connected to the two fixed rods; the plug-in block slidably connected to the fixed plate; a spring sleeved on the surface of the fixed rod between the plug-in block and the fixed plate; two snap-fit ​​blocks symmetrically fixedly connected at the opening of the fixed plate; the snap-fit ​​blocks snap-fit ​​and fixedly connected to the plug-in block; two positioning posts symmetrically fixedly connected inside the mounting seats; a fixed block slidably connected inside the mounting seats; the positioning posts and the fixed blocks are positioned correspondingly; symmetrically formed insertion slots at the center of the upper and lower sides of the fixed blocks; the insertion slots plug-fit and fixedly connected to the plug-in blocks; and an anti-wear plate fixedly connected to one side of the fixed block.

[0005] As a further embodiment of this utility model: a connecting block is fixedly connected to one side of the wear-resistant plate, and a connecting groove is provided on the side of the wear-resistant plate away from the connecting block, with the connecting block and the connecting groove corresponding to each other.

[0006] As a further embodiment of this utility model: two positioning grooves are symmetrically opened on the upper and lower sides of the wear-resistant plate, and a connecting frame is fixedly connected to one side of the wear-resistant plate, with the position of the connecting frame corresponding to the positioning groove.

[0007] As a further embodiment of this utility model: two limiting rods are symmetrically fixedly connected inside the connecting frame, and two movable plates are slidably connected through the two limiting rods. A spring is sleeved on the surface of the limiting rod located between the two movable plates.

[0008] As a further embodiment of this utility model: a limiting block is fixedly connected to the side of the movable plate away from the second spring, the limiting block is slidably connected to the connecting frame through it, and a pressure block is fixedly connected to one side of the movable plate.

[0009] As a further embodiment of this utility model: a positioning seat is slidably connected to the inner wall of the positioning groove, the positioning seat is in close contact with the limiting block, and a support plate is fixedly connected between the two positioning seats.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The heat-conducting grid flow stabilization and anti-wear device for circulating fluidized bed boilers is configured with an anti-wear plate, a slot, and a block. After aligning the fixed block on one side of the anti-wear plate with the mounting base, the anti-wear plate is moved so that it drives the fixed block to insert into the mounting base. At the same time, the slot is aligned with the block. The block is moved so that it squeezes the spring and inserts into the slot, thus fixing the fixed block inside the mounting base. This allows the anti-wear plate to be quickly and securely installed on one side of the water-cooled wall. 2. This heat-conducting grid flow stabilization and anti-wear device for circulating fluidized bed boilers, through the setting of a connecting frame, limiting block and support plate, the positioning seats on both sides of the support plate are aligned with the two sides of the positioning groove. Moving the support plate drives the positioning seats to insert into the positioning groove. At the same time, the positioning seats squeeze the limiting block, causing the limiting block to move into the connecting frame, squeezing the second spring inside the connecting frame. As the positioning seat is fully inserted into the positioning groove, the squeezing of the limiting block is released. The second spring drives the limiting block to reset and limit the positioning seat, thereby fixing the support plate between the two anti-wear plates, so that the support plate is stuck between the two anti-wear plates, supporting the anti-wear plates and preventing them from sagging when installed on the water-cooled wall surface.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-4 As shown, this utility model provides a technical solution: a heat-conducting grid flow stabilization and anti-wear device for circulating fluidized bed boilers, including a water-cooled wall 1, several mounting seats 2 are fixedly connected to one side of the water-cooled wall 1, and the mounting seats 2 are paired up to form a group. The upper and lower sides of the mounting seats 2 are symmetrically fixedly connected to fixing plates 3. Two fixing rods 4 are symmetrically fixedly connected inside the fixing plates 3. By setting the fixing rods 4, when the plug-in block 5 slides inside the fixing plate 3, the plug-in block 5 can slide outside the fixing rods 4, so that the fixing rods 4 can limit the movement of the plug-in block 5, so that the plug-in block 5 can be stably plugged and fixed with the plug-in groove 9. Two fixed rods 4 are slidably connected to the same plug block 5. The plug block 5 is slidably connected to the fixed plate 3. A spring 6 is sleeved on the surface of the fixed rod 4 between the plug block 5 and the fixed plate 3. Two snap-fit ​​blocks 7 are symmetrically fixed at the opening of the fixed plate 3. The snap-fit ​​blocks 7 are snap-fitted to the plug block 5. With the spring 6, while the plug block 5 is inserted into the plug groove 9, the plug block 5 squeezes the spring 6, so that the spring 6 generates a relative elastic force. This makes it easy for the spring 6 to drive the plug block 5 to reset through the elastic force, so that the plug block 5 is disengaged from the plug groove 9, and the limitation on the fixed block 8 is removed, making it easy to disassemble the anti-wear plate 10. The mounting base 2 has two symmetrically fixedly connected positioning posts 22 inside, and a fixing block 8 is slidably connected inside the mounting base 2. The positioning posts 22 and the fixing block 8 are correspondingly positioned. The fixing block 8 has symmetrically opened insertion slots 9 at the center of the upper and lower sides. The insertion slots 9 are inserted and fixedly connected to the insertion block 5. A wear-resistant plate 10 is fixedly connected to one side of the fixing block 8, and a connecting block 11 is fixedly connected to one side of the wear-resistant plate 10. A connecting slot 12 is opened on the side of the wear-resistant plate 10 away from the connecting block 11, and the connecting block 11 and the connecting slot 12 are correspondingly positioned. By setting the connecting block 11, the connecting block 11 on one side of the wear-resistant plate 10 is inserted into the connecting slot 12 of the other wear-resistant plate 10, thereby realizing the connection and fixation of the two wear-resistant plates 10, so that the wear-resistant plates 10 can be installed more stably on the surface of the water-cooled wall 1. The wear-resistant plate 10 has two symmetrical positioning grooves 13 on its upper and lower sides. A connecting frame 14 is fixedly connected to one side of the wear-resistant plate 10, and the position of the connecting frame 14 corresponds to that of the positioning groove 13. By setting the positioning groove 13, the positioning groove 13 is inserted into the positioning seat 21, so that the support plate 20 can be limited and fixed by the positioning seat 21 and the positioning groove 13, thereby allowing the support plate 20 to stably support the wear-resistant plate 10. Two limiting rods 15 are symmetrically fixedly connected inside the connecting frame 14. Two movable plates 16 are slidably connected through the two limiting rods 15. A spring 17 is sleeved on the surface of the limiting rods 15 between the two movable plates 16. By setting the limiting rods 15, the movable plates 16 slide inside the connecting frame 14, thereby allowing the movable plates 16 to slide on the surface of the limiting rods 15. This allows the limiting rods 15 to limit the movable plates 16, thus allowing the movable plates 16 to drive the limiting block 18 to move more stably. A limit block 18 is fixedly connected to the side of the movable plate 16 away from the spring 17. The limit block 18 is slidably connected to the connecting frame 14. A pressure block 19 is fixedly connected to one side of the movable plate 16. By setting the pressure block 19, the limit block 18 can be moved, so that the limit block 18 can remove the limit on the positioning seat 21, making it easy to remove the positioning seat 21. A positioning seat 21 is slidably connected to the inner wall of the positioning groove 13. The positioning seat 21 is close to the limiting block 18. A support plate 20 is fixedly connected between the two positioning seats 21. By setting the support plate 20, the upper and lower sides of the support plate 20 are close to the anti-wear plate 10, thereby supporting and fixing the anti-wear plate 10, preventing the anti-wear plate 10 from tilting during use, and improving the stability of the anti-wear plate 10 during use.

[0014] The working principle of this utility model is as follows: After aligning the fixing block 8 on one side of the wear-resistant plate 10 with the positioning post 22, insert the fixing block 8 into the mounting base 2, aligning the insertion slots 9 on both sides of the fixing block 8 with the insertion block 5. Move the insertion block 5 so that while the insertion block 5 compresses the spring 6, the insertion block 5 extends out of the fixing plate 3 and inserts into the insertion slot 9. As the insertion block 5 is inserted into the insertion slot 9, the locking block 7 locks into the insertion block 5 to fix the insertion block 5, allowing the insertion block 5 to fix the wear-resistant plate 10 through the insertion slot 9. Fix the wear-resistant plate 10 to the surface of the water-cooled wall 1, and then place the support plate 2... The positioning seats 21 on both sides are aligned with the positioning grooves 13. The support plate 20 is moved so that the support plate 20 drives the positioning seats 21 to insert into the positioning grooves 13 while pressing the limiting block 18. The limiting block 18 slides into the connecting frame 14, and the limiting block 18 presses the second spring 17. Thus, when the positioning seat 21 is fully inserted into the positioning grooves 13, the pressing on the limiting block 18 is released. The second spring 17 drives the limiting block 18 to reset, so that the limiting block 18 limits the positioning seat 21, thereby fixing the support plate 20 and allowing the support plate 20 to support and fix the wear-resistant plate 10.
