Description

Technical Field

[0001] This invention relates to the field of fluidized bed equipment technology, and more specifically, to a fluidized bed structure with external support. Background Technology

[0002] A fluidized bed is an engineering device in which a solid particulate material (usually powder or small particles) exhibits fluid-like behavior under the influence of a fluid (gas or liquid). Specifically, when a fluid (gas or liquid) flows upward through a layer of solid particles in a fluidized bed at a certain velocity, the drag force of the fluid on the particles gradually counteracts the gravity of the particles as the fluid velocity increases. When the flow velocity reaches a critical value, the solid particles begin to suspend in the fluid and move freely throughout the bed. At this point, the solid particle bed acquires some of the properties of a fluid (such as flowability and transport characteristics), and this state is called fluidization. Fluidized bed technology is widely used in particle handling processes in industries such as chemical, energy, and pharmaceutical.

[0003] Traditional cylindrical fluidized beds often encounter problems such as uneven fluidization, gas short-circuiting, and severe particle entrainment when processing materials with wide sieve size, easy separation, or severe particle agglomeration, resulting in low reaction efficiency and unstable operation. At the same time, the violent pulsation of the gas-solid two-phase flow, bubble collapse, and fan excitation during fluidized bed operation generate continuous vibration. The rigid support of traditional fluidized beds is prone to problems such as loosening of equipment foundation, cracking of welds, and failure of internal components under continuous vibration, which seriously affects the operational stability and service life of the equipment, and may even lead to structural safety accidents.

[0004] Therefore, it is necessary to provide a fluidized bed structure with external support to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fluidized bed structure with external support to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fluidized bed structure with external support, comprising: The fluidized bed body is truncated cone-shaped with a full cone angle of 8-10 degrees; A support ring is connected to the upper platform, and the support ring is sleeved on the upper side of the fluidized bed body; Multiple clamping components are disposed on the support ring and evenly distributed along the circumference of the support ring, for clamping and supporting the upper side of the fluidized bed body; Multiple lower support components are connected to the lower platform, and the multiple lower support components are evenly distributed around the lower side of the fluidized bed body to clamp and support the lower side of the fluidized bed body.

[0007] Furthermore, the clamping component includes: Radial limiting blocks and upper pads are respectively disposed on the inner and outer sides of the support ring, and a sliding column is slidably connected inside the radial limiting block; One end of the sliding column is provided with a first bolt rod that can be elastically extended and retracted, and the other end is connected to an upper support block. The radial limiting block, the upper pad block and the support ring are all provided with through holes that are adapted to the first bolt rod. A locking element is used to cooperate with the upper pad block and lock the position of the first bolt rod.

[0008] Furthermore, the sliding column has an internal cavity that is slidably connected to the inner end of the first bolt rod, and a first elastic element is provided between the inner wall of the internal cavity and the inner end of the first bolt rod.

[0009] Furthermore, a second elastic element is provided at the inner end of the sliding column, and the other end of the second elastic element is connected to the radial limiting block.

[0010] Furthermore, the lower support component includes: The lower support base has a slide block slidably connected to it. One end of the slide block is provided with a second bolt rod that can be elastically extended and retracted, and the other end is connected to the lower support block. The lower support base is provided with a lower pad and a locking member. The locking member is used to cooperate with the lower pad and lock the position of the second bolt rod.

[0011] Furthermore, the slide block has a sliding cavity inside that is slidably connected to one end of the second bolt rod, and a third elastic element is provided between the inner wall of the sliding cavity and the end of the second bolt rod.

[0012] Furthermore, a fourth elastic element is provided between the slide and the lower support base, and the fourth elastic element is sleeved on the outside of the second bolt rod.

[0013] Furthermore, both the upper pad and the lower pad are provided with a plurality of locking holes arranged in a ring; The locking component includes a locking nut, and both the first bolt rod and the second bolt rod are threadedly adapted to the locking nut. The locking nut is threadedly connected with a threaded bolt adapted to the locking hole.

[0014] Furthermore, the other end of the slide is provided with two support plates, and a connecting rod is rotatably connected between the two support plates. The outer end of the connecting rod is connected to the lower support block. The connecting rod is equipped with a limiting component, which works in conjunction with the support plate to lock the angle of the connecting rod.

[0015] Furthermore, the support plate is provided with an arc-shaped groove, and the limiting component includes a screw rod disposed on the connecting rod. The screw rod is slidably adapted to the arc-shaped groove, and a fastening nut is threadedly connected to the screw rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention sets the fluidized bed body as a frustum shape with a full cone angle of 8-10 degrees. By reasonably constraining the cone angle of the conical fluidized bed, higher production efficiency and better fluidization quality are achieved, the fluidization state is optimized, and the technical problems of uneven fluidization, gas short-circuiting and serious particle entrainment in traditional cylindrical fluidized beds are effectively solved, significantly improving reaction efficiency and operational stability.

[0017] 2. This invention achieves elastic clamping of the fluidized bed body on the upper side by using a support ring in conjunction with clamping components that are evenly distributed around the lower side. The lower support components are evenly distributed around the lower side to achieve elastic support on the lower side. The upper and lower components work together to form an omnidirectional stable external support. Unlike traditional internal support or a single rigid bottom support, this invention effectively dissipates the continuous vibration generated during the operation of the fluidized bed, avoids rigid impact, prevents the equipment foundation from loosening, weld cracking and internal component failure, greatly improves the operational stability and service life of the equipment, and effectively prevents structural safety accidents, resulting in higher safety.

[0018] 3. The lower support block of the present invention can be adjusted in angle by connecting rod, so that it can fit more closely with the fluidized bed body. This gives the lower support block the ability to adaptively adjust its angle, and can accurately fit the outer wall inclination angle at different heights of the frustum-shaped fluidized bed body. Compared with rigid support, the contact area is increased and the force per unit area is significantly reduced, greatly reducing wear. Attached Figure Description

[0021] The technical solutions of the embodiments 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, and 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.

[0022] Please see Figure 1-12 A fluidized bed structure with external support, comprising: The fluidized bed body 1 is shaped like a frustum with a full cone angle of 8-10 degrees. The fluidized bed body 1 has a shape that is wider at the top and narrower at the bottom, which can optimize the fluidization effect. Support ring 2 is connected to the upper platform and is sleeved on the upper side of fluidized bed body 1; Multiple clamping components 3 are disposed on the support ring 2 and are evenly distributed along the circumference of the support ring 2, for clamping and supporting the upper side of the fluidized bed body 1. Multiple lower support components 4 are connected to the lower platform and are evenly distributed around the lower side of the fluidized bed body 1 to clamp and support the lower side of the fluidized bed body 1.

[0023] First, the fluidized bed body 1 is shaped like a frustum with a full cone angle of 8-10 degrees, and the fluidized bed body 1 has a shape that is wide at the top and narrow at the bottom.

[0024] A numerical model of the fluidized bed reaction section was constructed to study the influence of the full cone angle on fluidization quality. Fluidization stability and uniformity were analyzed based on bed pressure drop and deviation values. Figure 11 As shown, with the increase of the full cone angle, the standard deviation of the pressure drop first increases and then decreases, maintaining a low level after 9°, then increasing, and decreasing significantly after 12°. This is consistent with the results of pressure drop and flow field analysis, indicating that under small cone angle conditions, increasing the standard deviation of the pressure drop is beneficial to improving the flow field near the interface, reducing bubble size, thereby improving the overall pressure drop pulsation and optimizing the fluidization effect, with a better effect after reaching 9°.

[0025] However, the standard deviation of pressure drop for models with cone angles between 11° and 15° is greater than that for the 9° model, while the standard deviations for pressure drop for the 16° and 18° models further decrease to levels similar to those of the 9° model. Therefore, to further quantify the uniformity of spatial distribution, the spatial deviation of gas velocity along the diameter direction for different cone angle models is calculated: The results are as follows Figure 12 As shown, with the increase of the full cone angle, there are two peak values ​​and two lower values. Among them, the 9° model has the smallest spatial distribution error of gas phase velocity, while the 12° and 18° models have the largest spatial distribution errors, differing by a factor of 8. Therefore, although increasing the full cone angle can reduce pressure drop fluctuations, it results in poor spatial distribution uniformity of the velocity, which is detrimental to the stability of chemical reactions.

[0026] In summary, an optimal cone angle of 8°-10° was selected for the fluidized bed reaction section. By rationally constraining the cone angle of the conical fluidized bed, higher production efficiency and better fluidization quality were achieved. The fluidization state was optimized, effectively solving the technical problems of uneven fluidization, gas short-circuiting, and severe particle entrainment in traditional cylindrical fluidized beds, and significantly improving reaction efficiency and operational stability.

[0027] In addition, the present invention, through the support ring 2 and the clamping components 3 evenly distributed around the circumference, can achieve elastic clamping on the upper side of the fluidized bed body 1; the lower support components 4 are evenly distributed around the lower side to achieve elastic support on the lower side. The upper and lower components work together to form an omnidirectional stable external support. Unlike the traditional internal support or single bottom rigid support, this invention effectively dissipates the continuous vibration generated during the operation of the fluidized bed, avoids rigid impact, prevents the equipment foundation from loosening, weld cracking and internal component failure, greatly improves the operational stability and service life of the equipment, and effectively prevents the occurrence of structural safety accidents, thus ensuring higher safety.

[0028] Furthermore, the circumferentially evenly distributed clamping components 3 and lower support components 4 achieve full circumferential wrapping support for the fluidized bed body 1, resulting in more uniform force distribution and avoiding structural damage caused by excessive local stress.

[0029] For preferred options, please refer to [link / reference]. Figure 1-5 The clamping component 3 includes: Radial limiting block 31 and upper pad block 32 are respectively disposed on the inner and outer sides of the support ring 2, and a sliding column 33 is slidably connected inside the radial limiting block 31; One end of the sliding column 33 is provided with a first bolt rod 34 that can be elastically extended and retracted, and the other end is connected to an upper support block 36. The radial limiting block 31, the upper pad block 32 and the support ring 2 are all provided with through holes that are adapted to the first bolt rod 34, that is, the other end of the first bolt rod 34 passes through the through holes of the radial limiting block 31, the support ring 2 and the upper pad block 32. The locking element 35 is used to cooperate with the upper pad 32 and lock the position of the first bolt rod 34.

[0030] Specifically, during installation, the support ring 2 is placed on the fluidized bed body 1, and after the support ring 2 is installed with the upper platform, pushing the first bolt rod 34 can drive the sliding column 33 to move. The sliding column 33 makes the upper support block 36 close to the fluidized bed body 1, and then the first bolt rod 34 is locked by the locking member 35, thus completing the limiting clamping of the upper part of the fluidized bed body 1.

[0031] The radial limiting block 31 provides precise sliding guidance for the sliding column 33, ensuring that the upper support block 36 can only move in a radial straight line, guaranteeing the accuracy of the support position and avoiding instability caused by offset. The elastic telescopic design of the first bolt rod 34, combined with the mechanical locking of the locking element 35, realizes the function of adjustable preload, which can adjust the support force according to the actual size and operating conditions of the fluidized bed body 1, making it highly adaptable; in addition, while providing preload through the elastic telescopic design of the first bolt rod 34, it also forms a flexible support, which can buffer the generated vibration.

[0032] For preferred options, please refer to [link / reference]. Figure 5The sliding column 33 has an inner cavity 5 that is slidably connected to the inner end of the first bolt rod 34. A first elastic element 6 is provided between the inner wall of the inner cavity 5 and the inner end of the first bolt rod 34. The first elastic element 6 in this application can be a spring or a damper.

[0033] With this design, the first elastic element 6 provides elastic preload. When the fluidized bed body 1 undergoes slight deformation due to temperature changes or vibration, it will drive the first elastic element 6 to extend and retract through the upper support block 36 and the sliding column 33. The first elastic element 6 automatically compensates for displacement through extension and retraction, always keeping the upper support block 36 in close contact with the outer wall of the equipment, achieving flexible support, thereby absorbing the vibration of the fluidized bed operation, reducing rigid impact, and reducing noise and fatigue damage.

[0034] For preferred options, please refer to [link / reference]. Figure 5 The inner end of the sliding column 33 is provided with a second elastic element 7, and the other end of the second elastic element 7 is connected to the radial limiting block 31. The second elastic element 7 in this application can be a spring or a damper.

[0035] With this design, the second elastic element 7 applies a thrust toward the fluidized bed body 1 to the sliding column 33. The second elastic element 7 provides secondary elastic support and, together with the first elastic element 6, forms a double elastic buffer, which has a stronger buffering effect and further absorbs the vibration energy during the operation of the fluidized bed. This significantly reduces the impact of vibration on the support structure and fundamentally solves the problem of foundation loosening caused by continuous vibration.

[0036] In addition, the dual elastic structure gives the clamping component 3 a stronger adaptive adjustment capability, which can be adapted to the fluidized bed body 1 with different diameter errors, reducing the difficulty of equipment installation and debugging.

[0037] For preferred options, please refer to [link / reference]. Figure 1-3 The inner wall of the radial limiting block 31 is provided with a sliding groove 16, and the outer wall of the sliding column 33 is provided with a sliding block 17 that is slidably connected to the sliding groove 16.

[0038] With this design, when the sliding column 33 moves, it will drive the sliding block 17 to slide along the sliding groove 16, which fundamentally restricts the movement trajectory of the sliding column 33, eliminates the risk of deflection, jamming, or dislodging during the support process, and makes the movement of the sliding column 33 smoother, without jamming or swaying.

[0039] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 6-10 The lower support component 4 includes: The lower support base 41 has a slide block 42 slidably connected to it. One end of the slide block 42 is provided with a second bolt rod 43 that can be elastically extended and retracted, and the other end is connected to the lower support block 45. The lower support base 41 is provided with a lower pad 44 and a locking member 35. The locking member 35 is used to cooperate with the lower pad 44 and lock the position of the second bolt rod 43.

[0040] Specifically, after the lower support component 4 is installed on the lower platform, the second bolt rod 43 is pushed to move the slide 42, which in turn moves the lower support block 45, so that the lower support block 45 clamps the lower part of the fluidized bed body 1, providing a stable installation foundation and high overall strength.

[0041] The slide block 42 can slide on the lower support base 41. With the extension and retraction of the second bolt rod 43, the position of the lower support block 45 can be adjusted to fit the outer wall of the fluidized bed body 1. Compared with the fixed support, the fit and support area are greatly improved. Moreover, it is a flexible support with stronger cushioning. The elastic extension and retraction design of the second bolt rod 43, together with the mechanical locking of the locking part 35, realizes the function of adjustable preload. At the same time, the support radial direction is adjustable to adapt to different diameters of the fluidized bed body 1.

[0042] The upper and lower locking parts are universal, and the parts are standardized, making them easy to process, replace, and maintain.

[0043] For preferred options, please refer to [link / reference]. Figure 6 and Figure 9 The lower support base 41 is provided with a support groove 18, and the bottom of the slide block 42 is provided with a sliding rod 19 that is slidably connected to the support groove 18.

[0044] This design ensures that when the slide block 42 moves, it will cause the sliding rod 19 to slide along the support groove 18, making the slide block 42 slide more stably and with stronger load-bearing capacity, and providing reliable guidance to ensure that the slide block 42 will not tilt or deviate.

[0045] For preferred options, please refer to [link / reference]. Figure 8 The slide block 42 has a sliding cavity 8 that is slidably connected to one end of the second bolt rod 43. A third elastic element 9 is provided between the inner wall of the sliding cavity 8 and the end of the second bolt rod 43. The third elastic element 9 in this application can be a spring or a damper.

[0046] Specifically, the third elastic element 9 provides the lower elastic preload. When the fluidized bed body 1 undergoes slight deformation due to temperature changes or vibration, it will drive the third elastic element 9 to extend and retract through the lower support block 45 and the slide block 42. The third elastic element 9 automatically compensates for displacement through extension and retraction, always keeping the lower support block 45 in close contact with the outer wall of the equipment, achieving flexible support, thereby absorbing the vibration of the fluidized bed operation and reducing rigid impact.

[0047] The third elastic element 9 provides vertical elastic buffering for the lower support block 45, complementing the horizontal buffering of the clamping component 3, thus constructing a three-dimensional elastic support system in space, which has a more comprehensive effect on vibration suppression and better protection.

[0048] For preferred options, please refer to [link / reference]. Figure 6 and Figure 8-9 A fourth elastic element 10 is provided between the slide block 42 and the lower support base 41, and the fourth elastic element 10 is sleeved on the outside of the second bolt rod 43. The fourth elastic element 10 in this application can be a spring or a damper.

[0049] With this design, the fourth elastic element 10 provides another layer of buffer between the slide 42 and the lower support base 41. Working together with the third elastic element 9, it forms a multi-level buffer, which can dissipate vibration energy from the bottom more efficiently and has a better vibration reduction effect.

[0050] This structure evenly transmits the supporting force to the lower support base 41, avoiding bolt loosening or base deformation caused by excessive local stress, and enhancing the overall rigidity and stability of the lower support component 4.

[0051] In this embodiment, preferably, please refer to [reference needed]. Figure 1-9 Both the upper pad 32 and the lower pad 44 have multiple locking holes 11 arranged in a ring. The locking component 35 includes a locking nut 351, a first bolt rod 34 and a second bolt rod 43, both of which are threadedly adapted to the locking nut 351. The locking nut 351 is threadedly connected to a threaded bolt 352 that is adapted to the locking hole 11.

[0052] With this design, after adjusting the positions of the first bolt rod 34 and the second bolt rod 43, rotating the locking nut 351 so that it contacts the upper pad 32 or the lower pad 44, and then screwing in the threaded bolt 352 so that it enters the corresponding locking hole 11, will prevent the locking nut 351 from rotating, thus achieving anti-loosening locking. This achieves threaded locking of the first bolt rod 34 and the second bolt rod 43, preventing bolt loosening due to long-term vibration and ensuring the static locking reliability of the support structure. The adjustment, unlocking, and relocking operations of this structure are simple, and on-site debugging can be performed quickly.

[0053] In this embodiment, preferably, please refer to [reference needed]. Figure 6 and Figure 9-10 The other end of the slide block 42 is provided with two support plates 12, and a connecting rod 13 is rotatably connected between the two support plates 12. The outer end of the connecting rod 13 is connected to the lower support block 45. The connecting rod 13 is provided with a limiting component 14, which is used to lock the angle of the connecting rod 13 in cooperation with the support plate 12.

[0054] This design allows the lower support block 45 to rotate along with the connecting rod 13, ultimately making the lower support block 45 fit against the outer conical surface of the fluidized bed body 1. The angle of the lower support block 45 is adjustable, allowing it to fit more closely against the fluidized bed body 1. This gives the lower support block 45 the ability to adaptively adjust its angle, precisely fitting the outer wall inclination angle at different heights of the frustum-shaped fluidized bed body 1. Compared to rigid support, this design increases the contact area, significantly reduces the force per unit area, and greatly reduces wear.

[0055] After adjustment, the angle of the connecting rod 13 and the lower support block 45 is locked by the limiting component 14 to ensure that the lower support block 45 will not deflect during operation.

[0056] In this embodiment, preferably, please refer to [reference needed]. Figure 9-10 The support plate 12 has an arc-shaped groove 15. The limiting component 14 includes a screw 141 mounted on the connecting rod 13. The screw 141 is slidably adapted to the arc-shaped groove 15. A fastening nut 142 is threaded onto the screw 141.

[0057] With this design, when the connecting rod 13 is rotated, the screw 141 will slide along the arc groove 15. After adjusting to the appropriate angle, tightening the fastening nut 142 will press the support plate 12 to achieve locking.

[0058] The arc groove 15 provides a specific arc motion trajectory for the screw 141 and also limits the swing angle range of the connecting rod 13, ensuring the accuracy and safety of angle adjustment; the angle can be finely adjusted by loosening the fastening nut 142 and locked by tightening it, making the operation extremely convenient and greatly reducing the labor and time costs of equipment installation and subsequent debugging.

[0059] Preferably, pressure sensors 20 are installed on both the upper support block 36 and the lower support block 45.

[0060] With this design, when installing the support, observe the value of the pressure sensor 20, and adjust the position of the first bolt rod 34 and the second bolt rod 43 to tighten the support once the pressure reaches the set value.

[0061] The pressure sensor 20 can monitor the contact pressure between the support block and the fluidized bed body 1 in real time, providing accurate data feedback to operators and preventing overpressure damage to the equipment or insufficient pressure leading to support failure. It also realizes intelligent monitoring and safety early warning functions. When abnormal fluctuations occur in the support pressure, it can promptly detect changes in the equipment's operating status (such as loosening or increased vibration), providing data support for predictive maintenance of the equipment and effectively preventing structural safety accidents.

[0062] For preferred options, please refer to [link / reference]. Figure 1-2 , Figure 6 and Figure 9The outer wall of the support ring 2 is provided with multiple upper mounting blocks 21, and the lower support base 41 is provided with a lower mounting block 22. Both the upper mounting block 21 and the lower mounting block 22 are provided with mounting holes 23.

[0063] This design connects the upper platform via the upper mounting block 21 and mounting hole 23, and the lower platform via the lower mounting block 22 and mounting hole 23. By providing standardized mechanical connection interfaces, the support structure can be quickly and securely installed onto the upper and lower platforms, improving the equipment's assembly efficiency.
