Description

Technical Field

[0001] The invention belongs to the field of fans, in particular to a magnetic suspension centrifugal fan with vibration reduction and noise reduction. Background Art

[0002] The magnetic levitation blower is a mechanical device for conveying gas. It adopts magnetic levitation bearings, three-dimensional flow impellers, high-speed permanent magnet synchronous motors, and high-efficiency inverter speed regulation. When starting, it first suspends and then rotates. It has no friction, does not require lubrication, and has low noise. Therefore, it can improve the working environment when in use.

[0003] A patent application with publication number CN214945292U discloses a magnetic levitation noise reduction fan device, including a base, wherein two vertical plates are fixedly connected to the upper end of the base, a fan body is arranged between the two vertical plates, the fan body is fixedly connected to the base, a connecting piece is fixedly connected to the air inlet of the fan body, a filter plate is arranged at the connecting piece, a horizontal plate is fixedly connected to the filter plate, the horizontal plate is connected to the connecting piece through a disassembly and assembly device, and the two ends of the fan body are respectively connected to the two vertical plates through a high-efficiency buffer device, which can not only conveniently replace the filter plate in the connecting piece through the disassembly and assembly device, but also effectively prevent dust from entering the inside of the fan, and the high-efficiency buffer device can prevent the fan from shaking when it is working, thereby ensuring the stable operation of the fan body.

[0004] Although the above-mentioned device can reduce the dust entering the inside of the fan during use, the filter is prone to clogging after long-term use, resulting in insufficient air intake of the fan body, which will still cause the heat inside the fan to increase, thereby causing the fan to shake. In addition, a permanent magnet is provided inside the magnetic levitation fan, so it should be kept at a low temperature as much as possible during use. If the operating temperature continues to be too high, the magnetism of the permanent magnet may be weakened or even demagnetized, thereby failing to support the rotation of the fan, causing the high-speed rotating fan body to be damaged by friction and cannot be repaired.

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figures 1 to 8As shown, a magnetic levitation centrifugal fan with vibration reduction and noise reduction described in the present invention comprises a base 1, a fan casing 11 is fixedly installed on the top of the base 1, a fan duct 13 is fixedly installed on the side wall of the fan casing 11, an electric control box 12 is fixedly installed on the top of the fan casing 11, a dust removal and noise reduction device 2 is fixedly installed on the top of the fan casing 11 above the electric control box 12, an air inlet pump compartment 14 and an air outlet compartment 141 are fixedly installed on the outer wall of the fan casing 11, an air inlet duct 15 is fixedly installed on the outer wall of the air inlet pump compartment 14, an air outlet duct 151 is fixedly installed on the outer wall of the air outlet compartment 141, the air inlet duct 15 and the air outlet duct 151 are connected to the dust removal and noise reduction device 2, and the The dust removal and noise reduction device 2 includes: a cooling box 21 fixedly installed on the top of the fan casing 11, wherein the interior of the cooling box 21 is provided with a first empty box 22 and a water tank 23, a power rotating cylinder 24 rotatably installed at the bottom end of the center of the water tank 23; a top air intake block 27 fixedly installed on the top of the power rotating cylinder 24; a bottom air intake ring 25 rotatably installed on the outer wall of the bottom end of the power rotating cylinder 24, wherein the bottom air intake ring 25 is connected to the end of the air inlet pipe 15, and the air inlet pipe 15 passes through the upper end of the first empty box 22 and the bottom end of the first empty box 22 and is connected to the bottom air intake ring 25; an isolation block 28 fixedly installed on the upper side wall of the water tank 23, wherein the bottom end of the water tank 23 is provided with a transmission device 3.

[0033] It should be noted that, considering that dust may enter the inside of the magnetic levitation fan during use, if dust enters the inside of the fan, it may cause a lot of dust to adhere to the permanent magnet inside the fan, resulting in poor heat dissipation and abnormal noise during rotation. With long-term use, the heat inside the fan cannot be fully dissipated, causing the permanent magnet inside the fan to weaken and demagnetize due to continuous overheating, resulting in damage to the fan. In order to solve this problem, the following improvements have been made:

[0034] First, the air entering the fan needs to be filtered, so a cooling box 21 is provided at the top of the fan casing 11, and a first empty box 22 is provided inside the cooling box 21, and a power rotating cylinder 24 and a top air intake block 27 are provided at the central bottom end of the air inlet pipe 15 and the water tank 23. When in use, water is provided inside the water tank 23, and the height of the water is lower than the height of the bottom end of the isolation block 28, and an air pump is provided inside the air inlet pump compartment 14, which can inflate the interior of the air inlet pipe 15, and the air inlet pump compartment 14 is connected to the interior of the fan casing 11 and the air inlet pipe 15, and the water tank 23 and the isolation block 28 as well as the air inlet pipe 15 are in a connected state, so the air pump inside the air inlet pump compartment 14 draws air from the inside of the fan casing 11, inflates the interior of the water tank 23 from the position of the air inlet pipe 15, and then passes through the outer The air flows out from the wall, and then enters the pipe of the air outlet duct 151 through the bottom end of the isolation block 28, and then enters the interior of the air outlet bin 141 through the pipe of the air outlet duct 151, and then enters the interior of the fan casing 11 from the air outlet bin 141, thereby completing a cycle. During this cycle, the gas passing through the inside of the fan casing 11 enters the interior of the water tank 23 through the air inlet pump bin 14, and is discharged from the top air intake block 27, and the outside of the top air intake block 27 is submerged in water. When the gas comes up, the gas can be cooled and dust-removed, so that the dust is mixed with water, so that the clean air and the cooled air are discharged through the isolation block 28, thereby achieving the cooling effect. After the temperature inside the fan casing 11 drops, the noise problem during use can be prevented, thereby improving safety during use.

[0035] like Figure 4 , Figure 5 , Figure 7 As shown, the isolation block 28 includes a water mist isolation square bin 281 arranged inside the isolation block 28, the side wall of the water mist isolation square bin 281 is connected to the end of the air outlet pipe 151, the bottom end of the water mist isolation square bin 281 is provided with an opening, and an isolation membrane plate 282 is fixedly installed inside the water mist isolation square bin 281.

[0036] It should be noted that, considering the presence of water mist inside the water tank 23, the water mist needs to be blocked during use so that the air entering the air outlet pipe 151 is dry air. Therefore, a water mist isolation square bin 281 and an isolation membrane plate 282 are provided inside the isolation block 28, and the inner wall of the isolation membrane plate 282 is provided with a membrane that can block water molecules, so that the internal air entering the air outlet pipe 151 is dry air.

[0037] like Figure 7 As shown, a jet pipe 26 is fixedly mounted on the side wall of the top air intake block 27. The jet pipes 26 are distributed in a circular array with the top air intake block 27 as the center, and the jet pipes 26 are arc-shaped.

[0038] It should be noted that, considering that the gas coming out of the air inlet pipe 15 entering the top air inlet block 27 is large bubbles when floating up in the water, the air inside the large bubbles cannot fully contact with the water, and the dust inside the bubbles cannot fully contact with the water, resulting in reduced dust prevention effect. The top air inlet block 27 is provided with a jet pipe 26 on the outside, which can make the bubbles rotate and spray out through the jet pipe 26. Therefore, when the air inlet pipe 15 inflates the top air inlet block 27, the bubbles are no longer in one position and can continuously change their positions and angles through the jet pipe 26, thereby improving the heat dissipation and dust removal effects. When the heat dissipation and dust removal effects are increased, the internal temperature of the fan casing 11 is normal, and the problem of abnormal sounds and noise is reduced, thereby increasing the stability of the fan during use.

[0039] like Figures 7 and 8 As shown, the jet pipe 26 includes: a first fixed block 261 fixedly mounted on the inner wall of the end of the jet pipe 26; a second rotating block 262 rotatably mounted on the central side wall of the first fixed block 261; a striking rod 263 fixedly mounted on the outer wall of the second rotating block 262; and a first fan blade 264 fixedly mounted on the end of the second rotating block 262, wherein the first fan blade 264 is distributed in a circular array with the second rotating block 262 as the center.

[0040] It should be noted that in order to make the bubbles sprayed from the jet pipe 26 smaller and able to fully contact with water, a first fixed block 261, a second rotating block 262 and a striking rod 263 are provided on the inner wall of the end of the jet pipe 26, and a first fan blade 264 is provided at the end of the second rotating block 262, so that the first fan blade 264 is driven to rotate during the rotation of the jet pipe 26, and the rotation of the first fan blade 264 can drive the second rotating block 262 and the striking rod 263 to rotate, thereby breaking up the bubbles sprayed from the first fixed block 261, so that the sprayed bubbles can fully contact with water, thereby mixing the internal dust with the water, and the temperature is also reduced.

[0041] like Figures 3 to 6As shown, the transmission device 3 includes: a heat dissipation metal tube 36 fixedly installed at the bottom end of the cooling box 21; a bottom power rod 31 rotatably installed at the bottom end of the power rotating cylinder 24 and passing through the bottom end of the cooling box 21; a first gear 32 fixedly installed on the outer wall of the bottom power rod 31; a second fixed block 33 fixedly installed at the bottom end of the cooling box 21; a second power rod 34 rotatably installed at the center of the second fixed block 33, one end of the second power rod 34 is fixedly installed with a third gear 341, the third gear 341 is meshed with the first gear 32, and the other end of the second power rod 34 is fixedly installed with a fourth gear 342; a power pump box 35 fixedly installed at the end of the heat dissipation metal tube 36, a power blade 351 is fixedly installed inside the power pump box 35, the second power rod 34 passes through the center of the power pump box 35 and the power blade 351, and the power pump box 35 and the second power rod 34 are rotatably installed, the power blade 351 is fixedly installed with the second power rod 34, and the side wall of the power pump box 35 is fixedly installed with a second heat dissipation tube 39.

[0042] It should be noted that, considering that during use, the water inside the water tank 23 exchanges with the air inside the fan casing 11, thereby causing the problem of temperature rise, a transmission device 3 is provided at the bottom end of the cooling box 21, and the water inside the water tank 23 can be cooled and dissipated through the transmission device 3. First, the bottom power rod 31 is connected to the bottom end of the power rotating cylinder 24, so when the power rotating cylinder 24 rotates, it can drive the bottom power rod 31 to rotate, and the rotation of the bottom power rod 31 can drive the first gear 32 to rotate, and the first gear 32 is connected to the second power rod 34, thereby driving the power blades 351 on the outer wall of the second power rod 34 to rotate, and the rotation of the power blades 351 can enable the heat dissipation metal pipe 36 to pump the water inside the water tank 23 and transport it to the inside of the second heat dissipation pipe 39 through the power pump box 35, and one end of the second heat dissipation pipe 39 is connected to the power pump box 35, and the other end is connected to the inside of the water tank 23, so that the water inside the water tank 23 can be cooled through the heat dissipation metal pipe 36 and the second heat dissipation pipe 39.

[0043] like Figures 3 to 6 As shown, the transmission device 3 also includes: a gear fixing block 372 fixedly mounted at the bottom end of the cooling box 21; a third transmission rod 37 rotatably mounted inside the gear fixing block 372; and a second fan blade 373 fixedly mounted at the end of the third transmission rod 37.

[0044] It should be noted that a gear fixing block 372 and a second fan blade 373 are provided at the bottom end of the cooling box 21. When in use, the third transmission rod 37 can be driven by a motor to rotate, and the rotation of the third transmission rod 37 drives the second fan blade 373 to rotate, so that the second fan blade 373 blows air to the outer wall of the second heat dissipation tube 39, thereby improving the heat dissipation effect of the flowing water inside the second heat dissipation tube 39.

[0045] like Figures 3 to 6 As shown, the transmission device 3 also includes: a second gear 371 fixedly mounted on the outer wall of the third transmission rod 37; a third fixed block 381 fixedly mounted on the bottom end of the cooling box 21; a fourth transmission rod 38 rotatably mounted inside the third fixed block 381; a fifth gear 382 fixedly mounted on the end of the fourth transmission rod 38, and a sixth gear 383 fixedly mounted on the other end of the fourth transmission rod 38, the fifth gear 382 meshes with the fourth gear 342, and the sixth gear 383 meshes with the second gear 371.

[0046] It should be noted that, considering that the rotation of the bottom power rod 31 can drive the second fan blade 373 to rotate and blow air to the outer wall of the second heat dissipation tube 39, a fourth gear 342 is provided at the end of the second power rod 34, and a fourth transmission rod 38 is provided at the bottom end of the cooling box 21, so that the fourth gear 342 drives the third transmission rod 37 to rotate through the fourth transmission rod 38, thereby dissipating the heat of the outer wall of the second heat dissipation tube 39 and improving the heat dissipation effect.

[0047] like Figure 8 As shown, the length of the striking rod 263 is greater than the diameter of the air jet pipe 26 , and the length of the first fan blade 264 is the same as the diameter of the air jet pipe 26 .

[0048] It should be noted that the length of the striking rod 263 is greater than the diameter of the jet tube 26, so that when bubbles come out, the second rotating block 262 can fully contact the bubbles to disperse the bubbles, and the length of the first fan blade 264 is the same as the diameter of the jet tube 26, so that when the jet tube 26 rotates, it can drive the first fan blade 264 to rotate.

[0049] like Figure 7 As shown, a film for blocking water mist is arranged inside the isolation film plate 282 , and the isolation film plate 282 is located at the bottom end of the isolation block 28 .

[0050] It should be noted that a film for blocking water mist is arranged inside the isolation diaphragm plate 282, and the isolation diaphragm plate 282 is located at the bottom end of the isolation block 28. A film is arranged inside the isolation diaphragm plate 282, so that when air is inflated into the air outlet pipe 151 and enters the fan casing 11, water mist will not enter the fan casing 11, thereby ensuring that the air entering the fan casing 11 is dry and improving the safety of the use of the fan casing 11. The isolation diaphragm plate 282 is located at the bottom end of the isolation block 28. When in use, even if there is water mist attached to the bottom end of the isolation diaphragm plate 282, it will drip down and will not enter the interior of the isolation block 28.

[0051] like Figure 4 and Figure 7 As shown, a pump is provided inside the air intake pump compartment 14 to blow air into the air intake pump compartment 14, a one-way valve is provided inside the air intake pipe 15, and the interior of the cooling box 21 is in a completely sealed state.

[0052] It should be noted that a pump is provided inside the air inlet pump compartment 14 to blow air into the air inlet pump compartment 14, so that the gas is from the air inlet pipe 15 through the cooling box 21 and the water tank 23, out of the air outlet pipe 151, and enters the fan housing 11 again, thereby forming a cycle, which not only ensures the heat dissipation effect, but also ensures the safety and sealing. A one-way valve is provided inside the air inlet pipe 15 to prevent the air pressure inside the air inlet pipe 15 from flowing back when the air pressure is initially low. The interior of the cooling box 21 is in a completely sealed state, and the sealing of the water tank 23 is maintained, thereby improving the service life of the fan housing 11.

[0053] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
