Description

Technical Field

[0001] This utility model relates to the field of centrifugal impeller technology, and in particular to a centrifugal impeller mounting structure with high stability. Background Technology

[0002] The centrifugal impeller installation structure utilizes the rotation of the impeller and the force exerted on the air by the blades, giving the air centrifugal force, thereby achieving radial airflow and pressurization, and transporting the air from the central area of ​​the impeller to the periphery, meeting the needs of applications requiring gas flow such as ventilation, heat dissipation, and pneumatic conveying.

[0003] A search revealed Chinese patent publication number CN207701473U, which discloses a centrifugal impeller mounting structure. The structure includes an impeller body with two symmetrically connected connecting plates on its front sidewall. This centrifugal impeller mounting structure is simple. Two electromagnets are energized and attract each other, causing two clamps to move towards each other and engage with the rotating shaft. Further rotation of two threaded rods in opposite directions tightens the clamps. When the two electromagnets move towards each other, the airflow in the T-shaped cylinder changes, causing two T-shaped pistons to move towards each other. Two pressure blocks further secure the rotating shaft, increasing the fixing force. In addition... When the two threaded rods are threaded into the threaded holes on the clamp, the threaded rods push the first rotating rod, which in turn pushes the second rotating rod. The two pressure plates further secure the shaft. To disassemble, simply rotate the two threaded rods in opposite directions and then disconnect the external power supply. This achieves both easy disassembly and secure installation. However, after prolonged operation, dust from the fresh air will continuously adhere to the surface of the impeller. Over time, the dust accumulates, increasing the resistance to impeller rotation and disrupting its dynamic balance, leading to a decrease in airflow. In the long run, this will affect the ventilation effect and performance of the fresh air system. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a centrifugal impeller installation structure with high stability, which aims to improve the problem that dust will continuously adhere to the surface of the impeller body after long-term operation, resulting in a decrease in air volume.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highly stable centrifugal impeller mounting structure, comprising a fan housing, a motor fixedly connected inside the fan housing, an impeller frame fixedly connected to the output end of the motor, fan blades arranged on the outside of the impeller frame, a dust collection mounting plate arranged on the front side of the impeller frame, an annular mesh fixedly connected to the outside of the dust collection mounting plate, a plurality of fixing bolts 1 passing through the front side of the dust collection mounting plate at equal intervals, the ends of the plurality of fixing bolts 1 being threadedly connected to the front side of the impeller frame at equal intervals, a cylindrical mounting plate arranged on the front side of the fan housing, a plurality of fixing bolts 2 passing through the front side of the cylindrical mounting plate, the ends of the plurality of fixing bolts 2 being threadedly connected to the front side of the fan housing at equal intervals, and an mounting mechanism arranged at the bottom of the fan housing.

[0006] The above technical solution achieves stable and efficient fresh air delivery by rotating the impeller frame through the motor output, enabling the gas to complete energy conversion within the fan. Simultaneously, the dust collection mounting plate and the annular mesh intercept dust, and the dust collection components can be easily disassembled and cleaned with the help of fixing bolts one and two, as well as the cylindrical mounting plate. This effectively prevents the accumulation of a large amount of dust on the fan blades, ensures stable airflow, reduces fan operating noise, and improves the operational stability of the centrifugal impeller and the working efficiency of the fresh air system.

[0007] As a further description of the above technical solution:

[0008] The installation mechanism includes a mounting base plate, on the top of which a plurality of L-shaped brackets are fixedly connected. Each adjacent side of the plurality of L-shaped brackets is fixedly connected to the front and rear bottom ends of the fan housing. A plurality of rubber round pads are fixedly connected to the front and rear bottom sides of the mounting base plate. Mounting bolts are provided on the outside of the plurality of L-shaped brackets. Circular grooves are provided inside the plurality of mounting bolts. T-shaped rubber rings penetrate through the interior of the plurality of L-shaped brackets.

[0009] The above technical solution achieves a stable installation of the fan by using a rubber circular pad to absorb vibration energy, a T-shaped rubber ring to consume vibration energy and prevent vibration propagation, and a circular groove that works in conjunction with the T-shaped rubber ring to limit the vibration propagation path. This effectively reduces the vibration and noise generated during fan operation, prevents component damage due to vibration, extends the fan's service life, creates a quiet operating environment for users, and improves the user experience.

[0010] As a further description of the above technical solution:

[0011] A handle is fixedly connected to the front side of the dust collection mounting plate, and the handle has an arc-shaped design on the outside.

[0012] The above technical solution involves a handle fixedly connected to the front of the ash collection mounting plate, which has an arc-shaped design to fit the hand comfortably. When it is necessary to disassemble or install the ash collection mounting plate, the user can easily grasp the handle and more easily unscrew or tighten the fixing bolts.

[0013] As a further description of the above technical solution:

[0014] The fan casing has multiple mounting holes at the air outlet for connecting other components. The mounting holes on both sides are square holes, while the mounting holes in the middle are round holes.

[0015] The above technical solution utilizes mounting holes at the air outlet of the fan casing to connect other components. The square holes on both sides can accommodate components of specific shapes and installation methods, while the central circular hole facilitates compatibility with components featuring circular connection structures. This satisfies the installation requirements of different components and enhances the versatility and flexibility of connecting the fan to other equipment.

[0016] As a further description of the above technical solution:

[0017] The outer diameter of the wind turbine frame is set to 135-140mm, and the width is set to 38.5-39.5mm. Preferably, the outer diameter is set to 138mm and the width is set to 39.1mm.

[0018] The above technical solution involves setting the outer diameter of the wind turbine frame to 135-140mm and the width to 38.5-39.5mm, with a preferred outer diameter of 138mm and a width of 39.1mm. This dimensional design ensures precise matching with other internal components of the wind turbine, guaranteeing a reasonable gas flow path within the wind turbine when the wind turbine frame drives the fan blades to rotate. The airflow can smoothly enter the impeller center from the axial direction and be efficiently thrown towards the outer edge of the impeller under centrifugal force, converting it into kinetic and pressure energy. This achieves stable and efficient gas delivery while ensuring the stability and balance of the wind turbine during operation.

[0019] As a further description of the above technical solution:

[0020] The top of both the fixing bolt and the T-shaped rubber ring is provided with a hexagonal groove, and the exterior of the multiple hexagonal grooves is designed with chamfers.

[0021] The aforementioned technical solution utilizes hexagonal grooves at the top of the fixing bolt and the T-shaped rubber ring to facilitate operation with a hex wrench, improving installation and disassembly efficiency. The external chamfered design prevents tools from failing to align properly with the hexagonal groove edge during operation due to angle issues.

[0022] As a further description of the above technical solution:

[0023] The wind turbine frame has a smooth exterior design and a symmetrical design.

[0024] The above technical solutions involve a smooth external design for the wind turbine frame, which reduces the resistance to gas flow inside the wind turbine, allowing the gas to flow more smoothly between the wind turbine frame and other components, thus reducing energy loss. The symmetrical design ensures the dynamic balance of the wind turbine frame during high-speed rotation, reduces vibration caused by uneven mass distribution, and thus reduces noise.

[0025] As a further description of the above technical solution:

[0026] The mounting base plate has a square shape, and all four sides of the mounting base plate have a rounded design.

[0027] The above technical solution utilizes a square mounting base, which easily matches common square mounting surfaces, increasing installation stability and fit. The rounded edges prevent scratches to operators during installation and also prevent scratches and damage to other surfaces.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor output drives the impeller frame to rotate, so that the gas completes energy conversion in the fan to achieve fresh air delivery. At the same time, the dust collection mounting plate and the annular mesh intercept dust. Then, with the help of fixing bolt one, fixing bolt two and cylindrical mounting plate, the dust collection components can be easily disassembled and cleaned, thus achieving stable and efficient fresh air delivery, effectively avoiding the accumulation of a large amount of dust on the fan blades, ensuring stable air volume, reducing fan operating noise, and improving the operating stability of the centrifugal impeller and the working efficiency of the fresh air system.

[0030] 2. In this utility model, the rubber round pad absorbs vibration energy, the T-shaped rubber ring consumes vibration energy and prevents vibration propagation, and the round groove and the T-shaped rubber ring cooperate to limit the vibration propagation path, thus achieving a stable installation of the fan, effectively reducing the vibration and noise generated during the operation of the fan, avoiding damage to components due to vibration, extending the service life of the fan, creating a quiet operating environment for users, and improving the user experience.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 2 , Figure 4 and Figure 5 An embodiment of this utility model provides a centrifugal impeller mounting structure with high stability, including a fan housing 1, a motor 3 fixedly connected inside the fan housing 1, an impeller frame 4 fixedly connected to the output end of the motor 3, fan blades 5 arranged on the outside of the impeller frame 4, a dust collection mounting plate 6 arranged on the front side of the impeller frame 4, an annular mesh surface 7 fixedly connected to the outside of the dust collection mounting plate 6, a plurality of fixing bolts 8 passing through the front side of the dust collection mounting plate 6 at equal intervals, the ends of the plurality of fixing bolts 8 being threadedly connected to the front side of the impeller frame 4 at equal intervals, a cylindrical mounting plate 9 arranged on the front side of the fan housing 1, a plurality of fixing bolts 10 passing through the front side of the cylindrical mounting plate 9, the ends of the plurality of fixing bolts 10 being threadedly connected to the front side of the fan housing 1 at equal intervals, and an mounting mechanism 2 arranged at the bottom of the fan housing 1;

[0040] The motor 3 includes a rotor magnetic ring and a plastic-encapsulated stator. The rotor magnetic ring is fixed in a ring shape to the inner wall of the middle part of one side of the fan blade 5, while the plastic-encapsulated stator is movably connected to the inner side of the rotor magnetic ring through a magnetically levitated air gap, and the air gap between the two is 0.2-2mm. In this embodiment, the iron core inside the plastic-encapsulated stator can be selected as a twelve-slot ten-pole or twelve-slot fourteen-pole structure.

[0041] Specifically, when the fresh air system is started, the output end of motor 3 immediately enters a high-speed rotation state. Since the output end of motor 3 is fixedly connected to the impeller frame 4, the impeller frame 4 will rotate synchronously with the rotation of the output end of motor 3. The fan blades 5 set on the outside of the impeller frame 4 also begin to rotate at high speed under the drive of the impeller frame 4. At this time, the gas enters the center of the impeller from the fan axis, and the blades of the fan blades 5 push the gas to rotate at high speed. Under the action of centrifugal force, the gas is thrown to the outer edge of the impeller, and its kinetic energy and pressure are greatly increased. Then the high-speed gas enters the volute-shaped channel, and the speed gradually increases. As the pressure gradually decreases, the kinetic energy is further converted into static pressure energy, and finally the high-pressure gas is discharged through the air outlet, completing the conveying or pressurization process and realizing the fresh air delivery process. During the continuous operation of the impeller, dust and impurities in the air will move with the airflow. Because the dust collection mounting plate 6 is located on the front side of the impeller frame 4 and is fixedly connected to the annular mesh 7, dust and impurities will be intercepted on the annular mesh 7 under the push of the airflow. Over time, more and more dust accumulates on the annular mesh 7. When it is necessary to clean the dust, use a tool to unscrew the fixing bolt 10. Bolt 210 penetrates the cylindrical mounting plate 9, with its end threaded to the front side of the fan housing 1. After unscrewing bolt 210, the cylindrical mounting plate 9 can be removed from the fan housing 1, exposing components such as the dust collection mounting plate 6 inside the fan. Next, unscrew bolt 18, which equidistantly penetrates the dust collection mounting plate 6 and has its end threaded to the front side of the impeller frame 4. After unscrewing multiple bolts 18, the dust collection mounting plate 6 and the annular mesh 7 can be removed from the impeller frame 4. Then, the removed dust collection mounting plate 6 and the annular mesh 7 are... Clean the surface to remove accumulated dust and impurities. After cleaning, reinstall the components in reverse order. First, securely fix the dust collection mounting plate 6 to the front of the impeller frame 4 with fixing bolt 1 8. Then, install the cylindrical mounting plate 9 on the front of the fan housing 1 and tighten it with fixing bolt 2 10. This allows for easy disassembly and cleaning of the dust collection mounting plate 6 and the annular mesh surface 7, effectively preventing the fan blades 5 from accumulating a large amount of dust due to prolonged use. This ensures stable airflow, improves the stability of the centrifugal impeller operation, and enhances the efficiency of the fresh air system.

[0042] Reference Figure 1 , Figure 2 and Figure 3The installation mechanism 2 includes an installation base plate 201. Multiple L-shaped brackets 202 are fixedly connected to the top of the installation base plate 201. The adjacent sides of the multiple L-shaped brackets 202 are fixedly connected to the front and rear bottom ends of the fan housing 1. Multiple rubber round pads 203 are fixedly connected to the front and rear bottom sides of the installation base plate 201. The exterior of the multiple L-shaped brackets 202 is provided with mounting bolts 204. The interior of the multiple mounting bolts 204 is provided with round grooves 205. T-shaped rubber rings 206 pass through the interior of the multiple L-shaped brackets 202.

[0043] Specifically, the mounting base 201 is placed in the predetermined installation position. Multiple L-shaped brackets 202, fixedly connected to the top of the mounting base 201, are securely connected to the front and rear bottom ends of the fan housing 1, thus stably supporting the fan housing 1. During the installation process, installers use mounting bolts 204 to fix the entire mounting mechanism 2 to the mounting surface. The mounting bolts 204 are located on the outside of the L-shaped brackets 202, and have circular grooves 205 inside. When the fan is put into operation, the motor 3 drives the impeller frame 4 and fan blades 5 to rotate at high speed. This process generates a certain degree of vibration and noise. At this time, multiple rubber round pads 203 fixedly connected to the front and rear bottom sides of the mounting base 201 can provide initial shock absorption. Once the vibration generated by the fan is transmitted to the mounting base 201, the rubber round pads 203 will deform due to their elasticity. The T-shaped rubber ring 206 absorbs some of the vibration energy, thereby reducing the transmission of vibration to the mounting surface and reducing the noise generated by vibration. The vibration generated by the operation of the fan will also propagate along the L-shaped bracket 202. The T-shaped rubber ring 206, made of rubber, has good damping performance. When the vibration is transmitted to the T-shaped rubber ring 206, the rubber ring will undergo elastic deformation. In this process, the vibration energy will be converted into the internal energy of the rubber and consumed. At the same time, the T-shaped rubber ring 206 tightly penetrates the inside of the L-shaped bracket 202, which can effectively prevent the vibration from propagating between the L-shaped brackets 202 and prevent the vibration from propagating to other components through the L-shaped brackets 202, thereby preventing the generation of additional noise. The T-shaped rubber ring 206 inside the circular groove 205 further restricts the propagation path of the vibration, so that the noise is continuously weakened during the propagation process, effectively reducing the noise generated by the operation of the fan.

[0044] Reference Figure 1 , Figure 2 and Figure 5The front side of the dust collection mounting plate 6 is fixedly connected to a handle 11, which has an arc-shaped design. Multiple mounting holes 12 for connecting other components are provided at the air outlet of the fan housing 1. The mounting holes 12 on both sides are square, while those in the middle are round. The outer diameter of the impeller frame 4 is 135-140mm, and the width is 38.5-39.5mm. Preferably, the outer diameter is 138mm and the width is 39.1mm. Hexagonal grooves 13 are provided at the top of the fixing bolt 8 and the T-shaped rubber ring 206, and the outer edges of the hexagonal grooves 13 are chamfered. The impeller frame 4 has a smooth outer design and a symmetrical design. The mounting base plate 201 has a square shape, and all four sides of the mounting base plate 201 have a smooth outer design.

[0045] Specifically, the handle 11 fixedly connected to the front of the dust collection mounting plate 6 has an arc-shaped design that fits the hand comfortably. When it is necessary to disassemble or install the dust collection mounting plate 6, the user can easily hold the handle 11 and more easily unscrew or tighten the fixing bolts 8. The mounting holes 12 at the air outlet of the fan housing 1 are used to connect other components. The square holes on both sides can adapt to components with specific shapes and installation methods, while the circular hole in the middle is more convenient to cooperate with some components with circular connection structures, meeting the installation requirements of different components and enhancing the versatility and flexibility of connecting the fan with other equipment. The outer diameter of the impeller frame 4 is set at 135-140mm, and the width is set at 38.5-39.5mm, preferably 138mm and 39.1mm. This size design is to ensure precise cooperation with other internal components of the fan, ensuring that when the impeller frame 4 drives the fan blades 5 to rotate, the gas flow path in the fan is reasonable, and the airflow can smoothly enter the impeller center from the axial direction and be efficiently thrown to the outer edge of the impeller under the action of centrifugal force. The gas is converted into kinetic and pressure energy, thereby achieving stable and efficient gas delivery. Simultaneously, it ensures the stability and balance of the impeller during operation. The hexagonal groove 13 at the top of the fixing bolt 8 and the T-shaped rubber ring 206 facilitates operation with a hex wrench, improving installation and disassembly efficiency. The external chamfer design prevents tools from being difficult to fit with the hexagonal groove 13 due to angle issues during operation. The smooth external design of the impeller frame 4 reduces resistance to gas flow inside the fan, allowing gas to flow more smoothly between the impeller frame 4 and other components, reducing energy loss. The symmetrical design ensures the dynamic balance performance of the impeller frame 4 during high-speed rotation, reducing vibration caused by uneven mass distribution and thus reducing noise. The square shape of the mounting base plate 201 facilitates matching with common square mounting surfaces, increasing installation stability and fit. The smooth external design prevents scratches on operators during installation and also prevents scratches and damage to other object surfaces during installation.

[0046] Working principle: When the fresh air system is turned on, the output end of motor 3 begins to rotate at high speed. Since the output end of motor 3 is fixedly connected to the impeller frame 4, the impeller frame 4 will rotate synchronously with the rotation of the output end of motor 3. The fan blades 5 set on the outside of the impeller frame 4 rotate at high speed under the drive of the impeller frame 4. At this time, the gas enters the impeller center from the fan axis. The blades of fan blade 5 drive the gas to rotate at high speed. Under the action of centrifugal force, the gas is thrown to the outer edge of the impeller, and the kinetic energy and pressure increase significantly. The high-speed gas enters the volute-shaped channel, where the speed decreases, and the kinetic energy is further converted into static energy. Pressure energy is applied, and high-pressure gas is discharged through the air outlet, completing the conveying or pressurization process to achieve the delivery of fresh air. During the continuous operation of the impeller, dust and impurities in the air will move with the airflow. Since the dust collection mounting plate 6 is located on the front side of the impeller frame 4 and is fixedly connected to the annular mesh 7, dust and impurities will be intercepted on the annular mesh 7 under the action of airflow. Over time, the dust accumulated on the annular mesh 7 will gradually increase. When it is necessary to clean the dust, use a tool to unscrew the fixing bolt 2 10, which penetrates the cylindrical shape. After unscrewing the mounting plate 9, which is threaded at the end to the front of the fan housing 1, and removing the fixing bolts 10, the cylindrical mounting plate 9 can be removed from the fan housing 1. At this time, the dust collection mounting plate 6 and other components inside the fan are exposed. Then, unscrew the fixing bolts 8, which are equidistant from the dust collection mounting plate 6 and threaded at the end to the front of the impeller frame 4. After unscrewing multiple fixing bolts 8, the dust collection mounting plate 6 and the annular mesh 7 can be removed from the impeller frame 4. The removed dust collection mounting plate 6 and the annular mesh 7 should then be cleaned. After removing accumulated dust and impurities, reinstall the equipment in reverse order. First, fix the dust collection mounting plate 6 to the front of the impeller frame 4 with fixing bolt 1 8 to ensure a firm installation. Then, install the cylindrical mounting plate 9 on the front of the fan housing 1 and tighten it with fixing bolt 2 10. This allows for easy disassembly and cleaning of the dust collection mounting plate 6 and the annular mesh surface 7, effectively preventing the accumulation of a large amount of dust on the fan blades 5 after prolonged use. This ensures stable airflow and improves the stability of the centrifugal impeller operation and the working efficiency of the fresh air system.

[0047] Furthermore, during installation, the mounting base plate 201 is placed in the predetermined installation position. Multiple L-shaped brackets 202 are fixedly connected to the top of the mounting base plate 201, with their adjacent sides fixedly connected to the front and rear bottom ends of the fan housing 1, thus stably supporting the fan housing 1. During installation, the entire mounting mechanism 2 is fixed to the mounting surface using mounting bolts 204. The mounting bolts 204 are located on the outside of the L-shaped brackets 202, and have circular grooves 205 inside. When the fan is running, the motor 3 drives the impeller frame 4 and fan blades 5 to rotate at high speed, generating some vibration and noise. Multiple rubber round pads 203 fixedly connected to the front and rear bottom sides of the mounting base plate 201 can provide initial shock absorption. When the vibration generated by the fan is transmitted to the mounting base plate 201, the rubber round pads 203 can absorb some of the vibration energy through their elastic deformation, reducing the vibration transmitted to the mounting surface. The vibration generated by the fan propagates along the L-shaped bracket 202. Due to the properties of its rubber material, the T-shaped rubber ring 206 has good damping performance. When the vibration is transmitted to the T-shaped rubber ring 206, the rubber ring will undergo elastic deformation. In this process, the vibration energy is converted into the internal energy of the rubber and consumed. At the same time, the T-shaped rubber ring 206 tightly penetrates the inside of the L-shaped bracket 202, which can effectively prevent the transmission of vibration between the L-shaped brackets 202 and prevent the vibration from propagating to other components through the L-shaped brackets 202 and generating additional noise. In addition, the circular groove 205 inside the mounting bolt 204, together with the T-shaped rubber ring 206, further restricts the propagation path of the vibration, so that the noise is continuously weakened during the propagation process, effectively reducing the noise generated during the operation of the fan and providing a quieter operating environment.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
