Description

Technical Field

[0001] This invention relates to the field of fluidized bed technology, specifically to a fixing system for an ultra-large wall-mounted fluidized bed and its working method. Background Technology

[0002] Large fluidized bed boilers, due to their large cylinder diameter, require the top pot's sidewall to be fixed to the wall. However, the entire diffuser section is a cantilever structure; therefore, the area furthest from the mounting hole in the diffuser section experiences the greatest deformation due to its own weight and the impact of the top pot's airtight seal. This affects the clearance between the top pot, diffuser section, and feed pot, preventing the feed pot from being pushed in. Therefore, it is essential to develop a fixing system and its operating method for ultra-large fluidized bed boilers mounted on the wall. Summary of the Invention

[0003] The purpose of this invention is to provide a fixing system for an ultra-large fluidized bed with walls mounted on the wall and its working method.

[0004] To address the aforementioned technical problems, this invention provides a fixing system for an ultra-large fluidized bed, comprising:

[0005] The container includes a top pot, a diffusion section, a slurry pot, a bottom pot, and a positioning component, wherein the outer wall of the top pot is fixed to the side wall of the wall.

[0006] The diffuser section is hinged to the side wall of the wall and is located below the top pot;

[0007] The feed pot is detachably disposed below the diffusion section, and the feed pot is suitable for carrying materials;

[0008] The bottom pot is fixed to the side wall of the wall, and the bottom pot is located below the broth pot;

[0009] The positioning element is fixed to the outer wall of the top pot, and the positioning element is adapted to limit the diffusion section;

[0010] The diffusion section moves downwards from the top of the pot with the hinge point as the axis, and the positioning element is adapted to limit the diffusion section.

[0011] When the flange of the diffuser section deforms and moves downward, the positioning element is adapted to support the diffuser section and prevent it from moving downward.

[0012] Preferably, the positioning component includes: a positioning bracket, a roller, and a fixing column. The positioning bracket is fixed to the outer wall of the flange of the top pot, and the positioning bracket is arranged along the axial direction of the top pot.

[0013] The fixing column is vertically fixed to the side wall of the positioning bracket;

[0014] The roller is sleeved on the outer wall of the fixed column, and the roller is adapted to abut against the flange of the diffuser section.

[0015] Preferably, a bearing is fixed to the inner ring of the roller, and the inner ring of the bearing is sleeved on the outer wall of the fixed column.

[0016] Preferably, a pressure plate is fixed to the end of the roller, and the pressure plate is adapted to seal the gap between the bearing and the end of the roller.

[0017] Preferably, a baffle is fixed to the outer ring of the diffuser flange. The baffle is arc-shaped and is adapted to abut against the outer wall of the top flange.

[0018] Preferably, a safety lock is fixed to the side wall of the top pot, and the movable end of the safety lock is adapted to move downward to limit the diffusion section.

[0019] Preferably, the safety lock includes: a safety cylinder, a locking tongue, a safety bracket, and a cylinder cover, wherein the safety bracket is fixed to the side wall of the top pot, and the safety cylinder is vertically fixed to the safety bracket;

[0020] The locking tongue is fixed to the movable end of the safety cylinder, and the locking tongue is adapted to abut against the baffle.

[0021] The cylinder cover is fitted onto the safety cylinder;

[0022] When the latch comes into contact with the baffle, the diffuser section cannot rotate around the hinge point.

[0023] Preferably, a limiting member is slidably disposed at the lower end of the diffusion section, and the limiting member is adapted to abut against the outer wall of the material pot.

[0024] Preferably, the top pot flange is fixed with an air seal, the air seal is hollow inside, the lower end of the air seal is wavy, and the air seal is suitable for sealing the top pot and the diffuser section.

[0025] On the other hand, the present invention also provides a method for operating a fixing system for an ultra-large fluidized bed, comprising the following steps:

[0026] Push the diffuser section so that it moves the lower end of the pot along the hinge point until the flange of the diffuser section abuts against the positioning part;

[0027] A gap is left between the top flange and the diffuser section to facilitate the opening or closing of the diffuser section;

[0028] When the upper flange of the diffuser section deforms and moves downward, the roller is adapted to support the flange of the diffuser section. When the diffuser section moves in and out, the bearing rotates, thereby causing the flange of the diffuser section to move upward.

[0029] After the diffuser section is limited by the positioning component, compressed air is supplied into the gas seal so that the gas seal can come into contact with the diffuser section flange, thereby achieving the sealing of the top pot and the diffuser section.

[0030] After the diffuser section is stopped, the safety cylinder is adapted to drive the locking tongue to move downward until the outer wall of the locking tongue abuts against the outer wall of the baffle to prevent the diffuser section from opening.

[0031] The beneficial effects of this invention are that the fixing system for an ultra-large fluidized bed with a wall-mounted structure, through the setting of positioning components, effectively positions and guides the diffusion section, enabling it to open or close smoothly; while the safety lock avoids the risk of accidental opening due to movement of the diffusion section. This improves the stability and safety of the equipment.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1, as Figures 1 to 7 As shown, this invention provides a fixing system for an ultra-large wall-mounted fluidized bed, comprising: a top pot 1, a diffuser section 2, a material pot 3, a bottom pot 4, and a positioning element 5. The outer wall of the top pot 1 is fixed to the side wall of a wall; the top pot 1 remains vertical; the diffuser section 2 is hinged to the side wall of the wall and is positioned below the top pot 1; the diffuser section 2 is adapted to rotate relative to the wall about the hinge point as an axis. When the diffuser section 2 rotates to below the top pot 1, the positioning element 5 is adapted to limit and guide the diffuser section 2, so that the top pot 1 and the diffuser section 2 are fixedly sealed. The material pot 3 is detachably disposed below the diffuser section 2, and the material pot 3 is adapted to carry materials; when the diffuser section 2 is limited and sealed by the positioning element 5, the material pot 3 is adapted to move horizontally to below the diffuser section 2, and the material pot 3 can be inserted between the diffuser section 2 and the bottom pot 4. However, when the diffuser section 2 deforms downward about the hinge point as an axis, the material pot 3 cannot enter between the diffuser section 2 and the bottom pot 4. The bottom pot 4 is fixed to the side wall of the wall and is located below the material pot 3. The positioning member 5 is fixed to the outer wall of the top pot 1 and is adapted to limit the diffuser section 2. The diffuser section 2 moves downward of the top pot 1 with the hinge point as the axis, and the positioning member 5 is adapted to limit the diffuser section 2. When the flange of the diffuser section 2 deforms and moves downward, this deformation and downward movement refers to the area of ​​the diffuser section 2 furthest from the hinge point tilting downward under its own weight and the pressure of the gas seal 15. This causes the gap between the flange at the upper end of the diffuser section 2 and the flange of the top pot 1 to increase, while the gap between the flange at the lower end of the diffuser section 2 and the flange of the material pot 3 increases. This deformation and downward movement not only prevents the material pot 3 from being pushed under the diffuser section 2, but also makes it difficult for the diffuser section 2 to separate from the top pot 1. The positioning member 5 is adapted to support the diffuser section 2 and prevent it from moving downward. The positioning member 5 is used to position and guide the diffuser section 2, allowing it to open or close smoothly.

[0046] Reference Appendix Figure 2 and Figure 3 The positioning component 5 includes a positioning bracket 51, a roller 52, and a fixing column 53. The positioning bracket 51 is fixed to the outer wall of the flange of the top pot 1 and is arranged axially along the top pot 1. The fixing column 53 is vertically fixed to the side wall of the positioning bracket 51 and is arranged radially along the top pot 1. The roller 52 is sleeved on the outer wall of the fixing column 53 and is adapted to rotate circumferentially relative to the fixing column 53. The roller 52 is adapted to abut against the flange of the diffuser section 2. When the flange of the diffuser section 2 deforms and moves downward, the positioning bracket 51 is adapted to support the flange of the diffuser section 2, while the diffuser section 2 continues to rotate about the hinge point. The flange of the diffuser section 2 abuts against the roller 52, and the roller 52 rotates circumferentially relative to the fixing column 53, which is adapted to push the flange of the diffuser section 2 upward, thereby limiting and guiding the diffuser section 2 to maintain a horizontal state and preventing the flange of the diffuser section 2 from deforming and moving downward away from the hinge point.

[0047] To improve the sealing performance between the diffuser section 2 and the top pot 1, an air seal 15 is fixed inside the flange of the top pot 1. The air seal 15 is hollow inside, and its lower end is wavy. The air seal 15 is designed to seal the top pot 1 and the diffuser section 2. After the diffuser section 2 moves below the top pot 1, compressed air is supplied into the air seal 15. The air seal 15 is adapted to expand and deform, thereby sealing the upper end of the diffuser section 2 and the top pot 1.

[0048] Reference Appendix Figure 3 and Figure 4 A bearing 54 is fixed to the inner ring of the roller 52, and the inner ring of the bearing 54 is fitted onto the outer wall of the fixed column 53. The bearing 54 reduces the friction between the roller 52 and the fixed column 53. A pressure plate 55 is fixed to the end of the roller 52, which is suitable for sealing the gap between the bearing 54 and the end of the roller 52. A retaining spring is fixed between the pressure plate 55 and the bearing 54, which is suitable for limiting the bearing 54 and preventing the bearing 54 from sliding along the axial direction of the fixed column 53. The outer wall of the pressure plate 55 abuts against the inner wall of the roller 52, and the roller 52 is suitable for circumferential rotation relative to the pressure plate 55. The pressure plate 55 prevents dust and impurities from the environment from entering the bearing 54, thereby improving the service life of the equipment.

[0049] Reference Appendix Figure 5A baffle 20 is fixed to the outer ring of the flange of the diffuser section 2. The baffle 20 is arc-shaped and adapted to abut against the outer wall of the flange of the top pot 1. The height of the baffle 20 is greater than the horizontal height of the flange of the diffuser section 2, and the horizontal height of the baffle 20 is less than the horizontal height of the safety lock 10. The baffle 20 is located on the side of the diffuser section 2 away from the positioning member 5. The cooperation between the baffle 20 and the safety lock 10 can prevent the diffuser section 2 from being opened by accidental operation.

[0050] Reference Appendix Figure 5 and Figure 6 A safety lock 10 is fixed to the side wall of the top pot 1. The movable end of the safety lock 10 is adapted to move downward. After the diffuser section 2 moves to the axial direction of the positioning member 5 with the hinge point as the axis and abuts, the movable end of the safety lock 10 moves downward, and the locking tongue 12 abuts against the baffle 20 to prevent the diffuser section 2 from moving arbitrarily. This limits the diffuser section 2. The safety lock 10 includes: a safety cylinder 11, a locking tongue 12, a safety bracket 13, and a cylinder cover 14. The safety bracket 13 is fixed to the side wall of the top pot 1, and the safety cylinder 11 is vertically fixed to the safety bracket 13. The safety cylinder 11 is located on the side of the top pot 1 away from the positioning member 5. After the diffuser section 2 is limited by the positioning member 5, the locking tongue 12 moves downward to limit the diffuser section 2. The cooperation between the safety lock 10 and the positioning member 5 is suitable for limiting the diffuser section 2 from both sides, preventing the diffuser section 2 from moving arbitrarily, and also preventing the diffuser section 2 from being accidentally opened during operation. The locking tongue 12 is fixed to the movable end of the safety cylinder 11, and the locking tongue 12 is adapted to abut against the baffle 20; the cylinder cover 14 is sleeved on the safety cylinder 11; when the locking tongue 12 abuts against the baffle 20, the diffuser section 2 cannot rotate around the hinge point. When the diffuser section 2 is closed, it is not possible for the diffuser section 2 to remain in a fixed position by its own weight alone, so the safety lock 10 is used to limit the diffuser section 2. When the locking tongue 12 moves downward to abut against the baffle 20, it can prevent the diffuser section 2 from opening; however, when it retracts upward, the locking tongue 12 can no longer limit the baffle 20, and the diffuser section 2 can open normally.

[0051] To improve the stability of the lower end of the diffuser section 2 in relation to the material pot 3, a limiting member 21 is slidably provided at the lower end of the diffuser section 2. The limiting member 21 is adapted to move vertically relative to the diffuser section 2, and a wheel is rotatably provided at the lower end of the limiting member 21. The wheel is adapted to abut against the outer wall of the material pot 3. When the material pot 3 is inserted between the bottom pot 4 and the diffuser section 2, the limiting member 21 moves downward, and the wheel abuts against the outer wall of the material pot 3, thereby limiting and fixing the material pot 3. The limiting member 21 is adapted to abut against the outer wall of the material pot 3.

[0052] Example 2: Based on Example 1, this example further provides a method for operating a fixing system for an ultra-large fluidized bed with walls, including a fixing system for an ultra-large fluidized bed with walls as described in Example 1. The specific structure is the same as in Example 1, and will not be repeated here. The specific method for operating a fixing system for an ultra-large fluidized bed with walls is as follows:

[0053] Push the diffuser section 2 so that it moves the lower end of the pot 1 with the hinge point as the axis until the flange of the diffuser section 2 abuts against the positioning piece 5;

[0054] A gap is left between the flange of the top pot 1 and the diffuser section 2 to facilitate the opening or closing of the diffuser section 2;

[0055] When the flange on the diffuser section 2 deforms and moves downward, the roller 52 is adapted to support the flange of the diffuser section 2. When the diffuser section 2 moves in and out, the flange of the diffuser section 2 moves upward through the rotation of the bearing 54.

[0056] When the diffuser section 2 is limited by the positioning element 5, compressed air is supplied into the gas seal 15 so that the gas seal 15 can come into contact with the flange of the diffuser section 2, thereby achieving the sealing of the top pot 1 and the diffuser section 2.

[0057] After the diffuser section 2 is stopped, the safety cylinder 11 is adapted to drive the locking tongue 12 to move downward until the outer wall of the locking tongue 12 abuts against the outer wall of the baffle 20 to prevent the diffuser section 2 from opening.
