Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluidized bed fan technology, specifically a fluidized bed fan with noise reduction function. Background Technology
[0002] The application background of fluidizing blowers is closely related to the need for efficient processing, transportation and reaction of solid materials in industrial production. Its development and application stem from the widespread adoption of "fluidization technology" in the industrial field, and fluidizing blowers are the core power equipment for realizing fluidization technology.
[0003] During the operation of fluidized bed fans, mechanical vibrations generate significant noise, which not only affects the comfort of the production environment but also poses potential hazards to the physical and mental health of operators. Furthermore, prolonged high-frequency vibrations can shorten the lifespan of the equipment itself and surrounding equipment. Therefore, effective noise reduction is a crucial requirement in industrial production.
[0004] Currently, existing fluidized bed fans commonly use vibration damping pads at their lower support legs to achieve noise reduction. This method works by using the elastic deformation of the damping pads to absorb vibration energy, thereby reducing the transmission of vibration to the ground and surrounding structures, and ultimately lowering noise. However, in existing technology, the damping pads are usually directly glued to the bottom of the support legs. This installation method has significant drawbacks: the adhesion is insufficient, and under the continuous vibration generated by the long-term operation of the fluidized bed fan, the damping pads are prone to displacement or even misalignment at the bottom of the support legs.
[0005] If the vibration damping pad becomes misaligned, its contact area with the support legs and the ground will change, disrupting the originally designed force balance and causing a significant decrease in vibration damping effect. This not only makes it impossible to effectively suppress the vibration of the fluidizing fan, but also causes noise control failure, thus failing to achieve the expected noise reduction effect. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this utility model provides a fluidizing fan with noise reduction function.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, the present invention provides the following technical solution: a fluidizing fan with noise reduction function, comprising a fluidizing fan body, a support frame and a base, wherein the fluidizing fan body is fixed on the support frame, the base is located below the support frame, multiple support plates are provided on both sides of the base, multiple base blocks are provided at the four corners of the bottom end of the support frame, and multiple shock-absorbing components are provided at the four corners of the base.
[0010] The base has slots at its four corners, through which the shock-absorbing components pass. A through hole is located at the center of the shock-absorbing components. A rod is inserted through the through hole at the lower end of the base block. The rod has an internal threaded hole inside. Multiple base plates are located below the base. A locking rod is inserted through the through hole at the upper end of the base plate and into the internal threaded hole. The locking rod is threadedly connected to the rod. The base block contacts the upper end of the shock-absorbing components, and the base plate contacts the lower end of the shock-absorbing components.
[0011] To facilitate assembly of the shock-absorbing component, the present invention includes the following improvement: the shock-absorbing component consists of two cylindrical tubes, with annular blocks fixedly installed at the upper and lower ends of the two cylindrical tubes respectively. A shock-absorbing sleeve is wrapped around the cylindrical tubes and the annular blocks. The two annular blocks are located at the upper and lower ends of the base respectively, with the bottom block contacting the annular block at the upper end of the base and the bottom plate contacting the annular block at the lower end of the base. The cylindrical tubes and the annular blocks are integrally formed.
[0012] Furthermore, an improvement of this utility model is that the shock-absorbing sleeve is made of rubber.
[0013] Furthermore, the present invention is improved in that the two cylindrical tubes are respectively provided with an annular groove and an annular protrusion at their mating ends, and the annular protrusion is inserted into the annular groove and threadedly connected to the annular groove.
[0014] Furthermore, an improvement of this utility model is that the outer wall of the shock-absorbing sleeve is provided with anti-slip texture.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a fluidizing fan with noise reduction function, which has the following beneficial effects:
[0017] As the core noise reduction structure, the vibration damping component uses rubber damping sleeves to efficiently absorb the vibration energy generated by the fluidizing fan body during operation through elastic deformation, reducing the transmission of vibration to the base and surrounding structures, thus reducing noise at the source. The tight fit between the upper and lower annular blocks and the base, combined with the clamping action of the bottom block and the base plate, avoids the noise reduction failure problem caused by the single contact and easy misalignment of traditional vibration damping pads, making the noise reduction effect more durable and stable.
[0018] The integrated molding structure of the cylindrical tube and the annular block eliminates the weak points of traditional splicing parts and improves the impact resistance of the shock absorption assembly; the threaded connection between the annular protrusion and the annular groove ensures that there is no loosening after the two cylindrical tubes are joined, further strengthening the integrity of the shock absorption assembly.

[0024] 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.
[0025] Please see Figures 1-4 The present invention provides a fluidizing fan with noise reduction function, comprising a fluidizing fan body 1, a support 2 and a base 3. The fluidizing fan body 1 is fixed on the support 2, the base 3 is located below the support 2, and multiple support plates 4 are provided on both sides of the base 3. Multiple base blocks 7 are provided at the four corners of the bottom end of the support 2, and multiple shock-absorbing components 5 are provided at the four corners of the base 3.
[0026] The base 3 has slots at its four corners, through which the shock-absorbing component 5 passes. The center of the shock-absorbing component 5 has a through hole 6. The bottom of the base block 7 has a rod 8 that passes through the through hole 6. The rod 8 has an internal threaded hole 9 inside. The base 3 has multiple base plates 11 below it. The upper end of the base plate 11 has a locking rod 10 that passes through the through hole 6 and is inserted into the internal threaded hole 9. The locking rod 10 is threadedly connected to the rod 8. The base block 7 contacts the upper end of the shock-absorbing component 5, and the base plate 11 contacts the lower end of the shock-absorbing component 5.
[0027] The shock-absorbing sleeve 15 is made of rubber.
[0028] The two cylindrical tubes 12 are respectively provided with annular grooves 13 and annular protrusions 14 at their joint ends. The annular protrusions 14 are inserted into the annular grooves 13 and are threadedly connected to the annular grooves 13. The outer wall of the shock-absorbing sleeve 15 is provided with anti-slip texture.
[0029] The anti-slip texture on the outer wall of the shock-absorbing sleeve 15 increases its friction with the bottom block 7 and the bottom plate 11. Combined with the positioning design of the through hole 6 through the insertion rod 8, it completely solves the problem of easy displacement and misalignment of traditional shock-absorbing pads.
[0030] Assembly and pre-installation of shock absorber component 5:
[0031] The shock-absorbing component 5 consists of two cylindrical tubes 12. Annular blocks are fixedly installed at the upper and lower ends of the two cylindrical tubes 12 respectively. Shock-absorbing sleeves 15 are wrapped around the cylindrical tubes 12 and the annular blocks. The two annular blocks are located at the upper and lower ends of the base 3 respectively. The bottom block 7 contacts the annular block at the upper end of the base 3, and the bottom plate 11 contacts the annular block at the lower end of the base 3. The cylindrical tubes 12 and the annular blocks are integrally formed.
[0032] First, connect the two cylindrical tubes 12: align the annular protrusion 14 of one cylindrical tube 12 with the annular groove 13 of the other, rotate the cylindrical tube 12 to complete the threaded connection, and form the complete shock absorption assembly 5 body.
[0033] Since the cylindrical tube 12 and the annular blocks at the top and bottom ends are integrally molded, the overall structure is stable after assembly and there is no risk of loosening.
[0034] The outer walls of the cylindrical tube 12 and the annular block are wrapped with rubber shock-absorbing sleeves 15. The anti-slip texture on the outer wall of the shock-absorbing sleeves 15 enhances the friction between them and subsequent components, preventing relative sliding.
[0035] The assembled shock-absorbing component 5 is inserted through the slots at the four corners of the base 3, so that the upper and lower annular blocks are respectively locked at the upper and lower ends of the base 3, thus completing the initial positioning of the shock-absorbing component 5 on the base 3.
[0036] The connection and fixation between bracket 2 and base 3:
[0037] Take bracket 2 and align the four corner blocks 7 at its bottom with the annular block at the top of base 3, so that the insert rod 8 at the bottom of the base block 7 vertically passes through the through hole 6 in the center of the shock absorber 5. At this time, the base block 7 naturally presses down on the annular block above the shock absorber 5, forming initial force contact.
[0038] Place the base plate 11 under the base 3, so that the locking rod 10 at the upper end of the base plate 11 passes through the through hole 6 of the shock absorption component 5, aligns with the internal thread hole 9 inside the insertion rod 8, and rotate the locking rod 10 to complete the threaded connection and lock it.
[0039] At this time, the base plate 11 is in close contact with the annular block below the shock absorber 5, and together with the upper base block 7, it forms an upper and lower clamping of the shock absorber 5, firmly fixing the bracket 2 to the base 3, ensuring that there is no gap or shaking between the bracket 2 and the base 3.
[0040] Installation and securing of the entire equipment:
[0041] Secure the fluidizing blower body 1 to the bracket 2, ensuring a firm connection between the fluidizing blower body 1 and the bracket 2. Finally, fix the support plate 4 to the equipment's mounting base with bolts to further enhance the overall structural stability and prevent displacement caused by vibration during equipment operation.
[0042] The shock-absorbing component 5 is quickly assembled via a threaded connection between the annular protrusion 14 and the annular groove 13, requiring no complex tools. The connection between the bracket 2 and the base 3 is achieved through the threaded engagement of the insert rod 8 through the through hole 6 and the locking rod 10 with the internal threaded hole 9, simplifying operation and significantly reducing installation time. The modular design of the overall structure allows for adjustment of the fixing position of the support plate 4 according to the size of different models of fluidized bed fans, resulting in greater adaptability.
[0043] The bottom block 7 and the bottom plate 11 clamp the shock-absorbing component 5 from the top and bottom, and together with the support plate 4, reinforce the overall structure, so that the vibration during the operation of the equipment is strictly limited inside the shock-absorbing component 5, avoiding long-term high-frequency vibration from causing wear on the fluidizing fan body 1, bracket 2 and connecting parts, and significantly extending the service life of the equipment and surrounding related components.
[0044] In summary, this fluidizing fan with noise reduction function achieves an integrated design of "vibration reduction-noise reduction-stability" through structural optimization. It not only solves the problems of easy failure and poor noise control of traditional vibration reduction methods, but also takes into account the convenience of installation and structural durability. It is suitable for industrial scenarios with high requirements for noise control and equipment stability.
