Description

Technical Field

[0001] This invention relates to the field of air suspension fan technology, specifically a multi-filtration air suspension fan. Background Technology

[0002] Air-suspended blowers are a new type of blower that utilizes air-suspended bearing technology and high-speed permanent magnet motor direct drive technology. Their working principle involves using air bearings to suspend the impeller shaft, eliminating contact between the impeller and the bearing during high-speed rotation, thus significantly reducing friction loss and mechanical noise. Simultaneously, the high-speed permanent magnet motor directly drives the impeller, improving motor efficiency and power factor. Air-suspended blowers offer advantages such as high efficiency and energy saving, stable operation, low noise, and low maintenance costs. They are widely used in aeration systems in industries such as wastewater treatment, electroplating, papermaking, and textiles, providing these industries with an efficient and stable air supply.

[0003] According to the announcement number CN118855775A, a multi-filtration air suspension fan includes a chassis, a fixed frame, a fixed bracket, a fan, and a side plate. The fixed frame is fixedly connected to both sides of the inner wall of the chassis, the fixed bracket is fixedly connected to the bottom of the inner wall of the fixed frame, the fan is fixedly connected to the top of the fixed bracket, and the side plate is disposed on the front side of the inner wall of the chassis.

[0004] Although this multi-filtration air suspension fan can be fixed with a bracket to make the fan more stable during operation, and the multi-filtration mechanism filters the air entering the casing, the equipment is difficult to deal with the diverse dust and impurities in complex environments, making it difficult to meet the strict standards for output air quality. Moreover, it lacks an effective cleaning mechanism, and dust easily adheres to the filter components, which not only hinders air circulation but also reduces the fan's working efficiency. Therefore, the device needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-filtration air suspension fan to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multi-filtration air suspension fan, including a fan housing, a filter cleaning mechanism fixedly connected to the top of the fan housing, a disassembly and assembly mechanism provided on the front of the fan housing, and a collection mechanism fixedly connected to the bottom of the fan housing;

[0007] The filter cleaning mechanism includes a drive component and an operating component, wherein the operating component is disposed on the surface of the drive component;

[0008] The drive assembly includes a vertical plate fixedly connected to the top right end of the fan housing. A motor is fixedly connected to the right side of the vertical plate, and a pole is fixedly connected to the left end of the motor. A support ring is fixedly connected to the top of the fan housing, and a first transmission wheel is rotatably connected to the left side of the support ring. A transmission belt is rotatably connected to the surface of the first transmission wheel, and a second transmission wheel is rotatably connected to the surface of the transmission belt. A sealing plate is fixedly connected to the middle of the top of the fan housing. A frame strip is inserted inside the fan housing, and a filter plate is fixedly connected inside the frame strip. A frame is fixedly connected inside the fan housing, and a rotating rod is rotatably connected inside the frame. A fan is fixedly connected to the right end of the rotating rod, and the surface of the rotating rod is fixedly connected to the inside of the second transmission wheel. A cleaning strip is fixedly connected to the left end of the rotating rod.

[0009] According to the above technical solution, a sealing opening is opened at the top of the fan housing, the surface of the sealing plate is tightly fitted with the inside of the sealing opening, a circular hole is opened inside the vertical plate, and the surface of the pole is rotatably connected to the inside of the circular hole.

[0010] According to the above technical solution, the operating component includes a circular base, which is fixedly connected to the top of the fan housing. A circular sleeve is slidably connected to the surface of the pole, and a circular ring is slidably connected to the surface of the circular sleeve. A T-shaped rod is rotatably connected to the left side of the circular sleeve. A spring is fixedly connected inside the T-shaped rod. A T-shaped piece is fixedly connected to the bottom end of the spring. An arc plate is fixedly connected to the top of the T-shaped piece. A locking rod is fixedly connected inside the arc plate. A positioning strip is fixedly connected to the top of the circular base. The right side of the circular ring is fixedly connected to the left side of the first transmission wheel.

[0011] According to the above technical solution, a positioning hole is opened inside the positioning strip, and the surface of the clamping rod matches the inside of the positioning hole. A limiting groove is opened inside the T-shaped rod, and the surface of the T-shaped part is slidably connected to the inside of the limiting groove. The motor drives the electric rod to rotate, which in turn drives the sleeve, the ring and the first transmission wheel to rotate, and correspondingly drives the first transmission wheel, the transmission belt and the second transmission wheel to rotate, which in turn drives the cleaning strip and the rotating rod to rotate. The cleaning strip can sweep off the attached dust, while large particles fall into the collection tank, thus effectively ensuring the filtration effect of the equipment.

[0012] According to the above technical solution, a transverse groove is formed inside the ring, and transverse bars are respectively provided at the upper and lower ends of the circular sleeve surface, with the transverse bars matching the interior of the transverse groove.

[0013] According to the above technical solution, a semi-circular groove is opened inside the circular seat, and the surface of the T-shaped circular rod matches the inside of the semi-circular groove. An opening is opened on one side of the semi-circular groove to perform a separate cleaning operation on one of the filter plates. At this time, when the moving arc plate drives the circular sleeve to move, it disengages from the inside of the ring, thereby releasing the rotational relationship between the ring and the first transmission wheel and the electric rod. This allows the first transmission wheel to not rotate when the electric rod rotates, thus enabling a separate cleaning operation on one of the filter plates.

[0014] According to the above technical solution, the disassembly and assembly mechanism includes a cover plate, which is disposed on the front of the fan housing. A circular strip is rotatably connected to the front of the fan housing. A T-shaped circular plate is fixedly connected to the surface of the circular strip. A dial ring is fixedly connected to the surface of the T-shaped circular plate. A slide block is fixedly connected to the surface of the fan housing. A slider is slidably connected inside the slide block. A connecting rod is fixedly connected to the left end of the slider. A locking block is fixedly connected to the left end of the connecting rod. A connecting strip is fixedly connected to the bottom of the slide block. A T-shaped rod is inserted into the bottom of the connecting strip. A hollow strip is fixedly connected to the surface of the circular strip. The front of the slider is located inside the hollow strip. The surface of the cover plate is fixedly connected to the surface of the frame strip.

[0015] According to the above technical solution, a positioning ring hole is opened on the surface of the dial ring, and the surface of the T-shaped rod matches the inside of the positioning ring hole. A latch is opened on the right side of the cover plate, and the surface of the latching block matches the inside of the latching block. The T-shaped rod is pulled out and disengaged from the latching position inside the dial ring. Then, the hollow strip is rotated to drive the slider to slide inside the slide block, thereby driving the connecting rod and the latching block to move, allowing the latching block to disengage from the latching position inside the cover plate. This allows the cover plate and filter plate to be easily pulled out and cleaned separately.

[0016] According to the above technical solution, the collection mechanism includes a collection trough, which is located inside the bottom of the fan housing. An outer cover is fixedly connected to the surface of the collection trough, and an mounting block is fixedly connected to the bottom front of the fan housing. Bolts are threaded onto the surface of the mounting block.

[0017] According to the above technical solution, the outer cover surface is provided with threaded holes, the bolt surface is threadedly connected to the inside of the threaded holes, the bottom end of the fan housing is provided with slots, and the surface of the collection tank is inserted into the inside of the slots. When cleaning the impurities collected into the collection tank, the bolts can be unscrewed and the outer cover and mounting block can be released from the fixing. Then the collection tank can be taken out from the inside of the fan housing and cleaned accordingly.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] 1. This multi-filtration air suspension fan, through its filtration and cleaning mechanism, uses a motor to drive a rotating rod, which in turn drives a circular sleeve, a circular ring, and a first transmission wheel to rotate. This, in turn, drives the first transmission wheel, the transmission belt, and the second transmission wheel, which in turn drive the cleaning strips and the rotating rod. The cleaning strips remove attached dust, while larger particles fall into the collection tank, effectively ensuring the filtration effect. Because multiple filter plates are installed, multiple filtration of dust is achieved, thus improving the filtration efficiency. The effective cleaning mechanism effectively prevents dust accumulation, ensures airflow, and improves the fan's working efficiency.

[0020] 2. This multi-filtration air suspension fan, through its set filter cleaning mechanism, can perform individual cleaning operations on a specific filter plate. At this time, when the moving arc plate drives the circular sleeve to move, it disengages from the inside of the circular ring, thereby releasing the rotational relationship between the circular ring and the first transmission wheel and the pole. This allows the individual first transmission wheel to be cleaned individually when the pole rotates.

[0021] 3. This multi-filtration air suspension fan, through its disassembly and assembly mechanism, allows the T-shaped rod to be pulled out and disengaged from the locking position inside the dial ring. Then, rotating the hollow strip drives the slider to slide inside the slide block, thereby causing the connecting rod and locking block to move, allowing the locking block to disengage from the locking position inside the cover plate. This makes it easy to pull out the cover plate and filter plate for separate cleaning.

[0022] 4. This multi-filtration air suspension fan, through its set collection mechanism, can clean the impurities collected inside the collection tank by unscrewing the bolts and removing the outer cover and mounting block. Then, the collection tank can be taken out from inside the fan housing and cleaned accordingly. Attached Figure Description

[0040] The filter cleaning mechanism 2 includes a drive component 21 and an operation component 22, with the operation component 22 disposed on the surface of the drive component 21;

[0041] Drive assembly 21 includes a vertical plate 211, which is fixedly connected to the top right end of the fan housing 1. A motor 212 is fixedly connected to the right side of the vertical plate 211, and a pole 213 is fixedly connected to the left end of the motor 212. A support ring 214 is fixedly connected to the top of the fan housing 1. A first transmission wheel 215 is rotatably connected to the left side of the support ring 214. A transmission belt 2151 is rotatably connected to the surface of the first transmission wheel 215, and a second transmission wheel 216 is rotatably connected to the surface of the transmission belt 2151. A sealing plate 2152 is fixedly connected to the middle of the top of the fan housing 1. A frame strip 2171 is inserted inside the fan housing 1. A filter plate 217 is fixedly connected inside the frame strip 2171. A frame 2172 is fixedly connected inside the fan housing 1. A rotating rod 2173 is rotatably connected inside the frame 2172. A fan 219 is fixedly connected to the right end of the rotating rod 2173. The surface of the rotating rod 2173 is flush with the interior of the second transmission wheel 216. The rotating rod 2173 is fixedly connected to the left end of a cleaning strip 218. A sealing opening is opened at the top of the fan housing 1. The surface of the sealing plate 2152 is tightly fitted to the inside of the sealing opening. A circular hole is opened inside the vertical plate 211. The surface of the electric rod 213 is rotatably connected to the inside of the circular hole. The operating component 22 includes a circular seat 221, which is fixedly connected to the top of the fan housing 1. A circular sleeve 222 is slidably connected to the surface of the electric rod 213. A circular ring 223 is slidably connected to the surface of the circular sleeve 222. A T-shaped rod 224 is rotatably connected to the left side of the circular sleeve 222. A spring 229 is fixedly connected inside the T-shaped rod 224. A T-shaped piece 225 is fixedly connected to the bottom end of the spring 229. An arc plate 226 is fixedly connected to the top of the T-shaped piece 225. A locking rod 228 is fixedly connected inside the arc plate 226. A positioning strip 227 is fixedly connected to the top of the circular seat 221. The right side of the circular ring 223 is fixedly connected to the left side of the first transmission wheel 215.

[0042] Furthermore, a positioning hole is opened inside the positioning strip 227, and the surface of the clamping rod 228 matches the inside of the positioning hole. A limiting groove is opened inside the T-shaped rod 224, and the surface of the T-shaped piece 225 is slidably connected to the inside of the limiting groove.

An opening is opened on one side of the semi-circular groove. The motor 212 drives the electric rod 213 to rotate, which in turn drives the sleeve 222, the ring 223 and the first transmission wheel 215 to rotate, and correspondingly drives the first transmission wheel 215, the transmission belt 2151 and the second transmission wheel 216 to rotate, which in turn drives the sweeping strip 218 and the rotating rod 2173 to rotate. The sweeping strip 218 can sweep off the attached dust, while large particles fall into the collection tank 41, thus effectively ensuring the filtration effect of the equipment.

[0043] Example 2

[0044] See Figure 1-11 Furthermore, based on Embodiment 1, the disassembly and assembly mechanism 3 includes a cover plate 31, which is disposed on the front of the fan housing 1. A round bar 32 is rotatably connected to the front of the fan housing 1. A T-shaped round plate 33 is fixedly connected to the surface of the round bar 32. A dial ring 34 is fixedly connected to the surface of the T-shaped round plate 33. A slide block 35 is fixedly connected to the surface of the fan housing 1. A slider 36 is slidably connected inside the slide block 35. A connecting rod 361 is fixedly connected to the left end of the slider 36. A locking block 37 is fixedly connected to the left end of the connecting rod 361. A connecting strip 351 is fixedly connected to the bottom of the slide block 35. A T-shaped rod 39 is inserted into the bottom of the connecting strip 351. A hollow strip 38 is fixedly connected to the surface of the round bar 32. The front of the slider 36 is located inside the hollow strip 38. The surface of the cover plate 31 is fixedly connected to the surface of the frame strip 2171.

[0045] Furthermore, a positioning ring hole is formed on the surface of the dial ring 34, and the surface of the T-shaped rod 39 matches the inside of the positioning ring hole. A latch is formed on the right side of the cover plate 31, and the surface of the latch block 37 matches the inside of the latch. The T-shaped rod 39 is pulled out and disengaged from the latch inside the dial ring 34. Then, the hollow strip 38 is rotated to drive the slider 36 to slide inside the slide block 35, thereby driving the connecting rod 361 and the latch block 37 to move, allowing the latch block 37 to disengage from the latch inside the cover plate 31. This allows the cover plate 31 and the filter plate 217 to be easily pulled out and cleaned separately.

[0046] Example 3

[0047] See Figure 1-11Furthermore, based on Embodiment 1, the collection mechanism 4 includes a collection trough 41, which is located inside the bottom of the fan housing 1. An outer cover 42 is fixedly connected to the surface of the collection trough 41, and an mounting block 43 is fixedly connected to the bottom front of the fan housing 1. Bolts 44 are threadedly connected to the surface of the mounting block 43.

[0048] Furthermore, a threaded hole is opened on the surface of the outer cover 42, and the surface of the bolt 44 is threadedly connected to the inside of the threaded hole. A slot is opened inside the bottom end of the fan housing 1, and the surface of the collection tank 41 is inserted into the inside of the slot. When cleaning the impurities collected inside the collection tank 41, the bolt 44 can be unscrewed and the outer cover 42 and the mounting block 43 can be released from the fixing. Then the collection tank 41 can be taken out from the inside of the fan housing 1 and cleaned accordingly.

[0049] In actual operation, when this device is used, when the air suspension fan is in use, dust in the air enters the equipment and is filtered by the filter plate 217. In addition, cleaning is required. At this time, the motor 212 drives the electric rod 213 to rotate, which in turn drives the circular sleeve 222, the circular ring 223 and the first transmission wheel 215 to rotate, and correspondingly drives the first transmission wheel 215, the transmission belt 2151 and the second transmission wheel 216 to rotate, which in turn drives the cleaning strip 218 and the rotating rod 2173 to rotate. The cleaning strip 218 can sweep off the attached dust, while large particles fall into the collection tank 41, thus effectively ensuring the filtration effect of the equipment.

[0050] Furthermore, since multiple filter plates 217 are provided, multiple filtration of dust can be performed. Therefore, the degree of clogging on each filter plate 217 varies. Thus, filter plates 217 that do not require cleaning do not need cleaning. At this time, when the moving arc plate 226 drives the circular sleeve 222 to move, it disengages from the inside of the circular ring 223, thereby releasing the rotational relationship between the circular ring 223, the first transmission wheel 215, and the electric pole 213. This means that when the electric pole 213 rotates, the individual first transmission wheel 215 does not need to rotate, allowing for individual cleaning of a single filter plate 217. Afterwards... The arc plate 226 is pulled upward to disengage the locking rod 228 from the positioning strip 227. After the T-shaped rod 224 moves into the round seat 221, the T-shaped rod 224 is rotated and the arc plate 226 is released to allow the locking rod 228 to engage with the positioning strip 227. During disassembly and cleaning, the T-shaped rod 39 is pulled out and disengaged from the locking position inside the dial ring 34. Then, the hollow strip 38 is rotated to drive the slider 36 to slide inside the slide seat 35, thereby driving the connecting rod 361 and the locking block 37 to move. This allows the locking block 37 to disengage from the locking position inside the cover plate 31, and the cover plate 31 and the filter plate 217 can be easily pulled out and cleaned separately.

[0051] In addition, when cleaning the impurities collected inside the collection tank 41, the bolts 44 can be unscrewed and the outer cover 42 and mounting block 43 can be released. Then the collection tank 41 can be taken out from inside the fan housing 1 and cleaned accordingly.
