Description

Technical Field

[0001] The present invention relates to the technical field of booster fan equipment, and in particular to an outer rotor spiral blade conical booster fan and a use method thereof. Background Art

[0002] The outer rotor spiral blade conical booster fan is a common air boosting equipment, usually used in ventilation, smoke exhaust, transportation and other applications in the industrial field. Its working principle is to inhale and accelerate air or gas through the rotation of the outer rotor spiral blade, and then pass through the compression effect of the conical booster chamber to finally output high-speed and high-pressure airflow. It can be used in ventilation systems in industrial plants, workshops and other places to help remove dirty air and keep the air fresh.

[0003] However, when the paint spraying plant discharges polluted air, the paint particles generated by the paint spraying process will be suspended in the air. When the air booster equipment is in use, it is necessary to inhale external air for pressurization and acceleration. When working in this environment for a long time, a large number of paint particles will adhere to the outer wall of the spiral fan blade, affecting the compression effect. In response to the above problems, the following solutions are proposed. Summary of the invention

[0006] The cleaning mechanism comprises a sliding rod slidably connected to the bottom of the air inlet housing, a sealing plate is fixedly connected to the side wall of the sliding rod, and an extrusion spring is fixedly connected to the side wall of the sealing plate.

[0007] Preferably, the shell mechanism also includes an inclined panel fixedly connected to the inner wall of the control slide groove, an electric motor is fixedly connected to the outer wall of the air inlet shell, a driving gear is rotatably connected to the side wall of the electric motor, and the outer wall of the driving gear is meshingly connected to the outer wall of the power gear.

[0008] Preferably, the shell mechanism also includes an air inlet rack fixedly connected to the inner wall of the through hole at the bottom of the air inlet shell, a pressurized conical tube is fixedly connected to the side wall of the air inlet shell, a support frame is fixedly connected to the inner wall of the pressurized conical tube, a fixing frame is fixedly connected to the bottom of the pressurized conical tube, and an end of the fixing frame away from the pressurized conical tube is fixedly connected to the equipment base.

Utilizing the inclined surface presented by the inclined panel, after the power of the electric motor is turned on, the electric motor drives the power gear to rotate through the driving gear, and the power gear drives the boosting spiral fan blade to pressurize and discharge external air through the driving rod. In addition, when the power gear and the power gear rotate, the sliding wheel is restricted by the inclined surface of the air inlet frame, forcing the pushing plate to be pushed outward along the outer wall of the collecting fan blade, so as to clean the side of the collecting fan blade and avoid the accumulation of excessive impurities on the side of the collecting fan blade, which affects the compression and gas transmission efficiency of the equipment.

[0010] Preferably, the pressurizing mechanism also includes a cleaning ring fixedly connected to the side wall of the pushing plate, a return spring fixedly connected to the inner wall of the cleaning ring, an end of the return spring away from the collecting blades is fixedly connected to a cleaning rod, and the side wall of the cleaning rod is slidably connected to the side wall of the pushing plate. In order to solve the problem that high-pressure gas always flows to low-pressure gas, the air inlet frame is set at the bottom of the air inlet shell by utilizing the regular movement of the pushing rod, and when the cross space of the collecting blades deflects upward due to rotation, it presents a Figure 4 In this state, the space between the collecting blades and the inner wall of the air inlet shell form a sealed space. At this time, the sliding wheel is restricted by the inclined surface of the inclined panel. When the sliding wheel reaches the top of the outer wall of the inclined panel, the pushing rod penetrates into the interior of the air inlet shell and pushes the air in the sealed space into the interior of the boosting spiral blades, while the high-pressure gas inside the boosting spiral blades is discharged from the outlet of the support frame, avoiding the problem of low boosting efficiency caused by the high pressure inside the boosting spiral blades affecting the entry of the collecting blade air.

[0011] Preferably, the cleaning mechanism also includes a scratch frame fixedly connected to the side wall of the sliding rod, the outer wall of the scratch frame is slidably connected to the inner wall of the air inlet frame, a fixed block is fixedly connected to the top of the equipment base, a boost pipe is fixedly connected to the top of the fixed block, the inner wall of the boost pipe is slidably connected to the outer wall of the sealing plate, and the centrifugal force generated by the rotation of the power gear is utilized. When the push plate rotates following the power gear, the centrifugal force forces the cleaning rod to extend outward along the outer wall of the push plate, and in this process, the cleaning rod will scratch the outer wall of the push plate. After the equipment completes processing and stops, the reset spring will release the accumulated mechanical power to drive the cleaning rod to reset and clean the outer wall of the push plate again to avoid paint particles adhering to the outer wall of the push plate, which affects the airtightness during the equipment pressurization process.

[0012] An outer rotor spiral blade conical booster fan and a method of using the same include the following steps:

[0013] S1: The device utilizes the inclined surface presented by the inclined panel. After the power of the electric motor is turned on, the electric motor drives the power gear to rotate through the driving gear.

[0014] S2: When the cross space of the collecting blades deflects upward due to rotation, the space between the collecting blades forms a sealed space with the inner wall of the air intake shell, pushing the rod to penetrate into the interior of the air intake shell and push the air in the sealed space into the interior of the boosting spiral blades.

[0015] S3: Centrifugal force forces the cleaning rod to extend outward along the outer wall of the push plate. During this process, the cleaning rod will scrape the outer wall of the push plate. After the equipment completes the processing, the reset spring will release the accumulated mechanical power to drive the cleaning rod to reset.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention utilizes the inclined surface presented by the inclined plate. After the power of the electric motor is turned on, the electric motor drives the power gear to rotate through the driving gear, and the power gear drives the booster spiral blade to pressurize and discharge the external air through the driving rod. In addition, when the power gear and the power gear rotate, the sliding wheel is restricted by the inclined surface of the air inlet frame, forcing the push plate to be pushed outward along the outer wall of the collecting blade, thereby cleaning the side of the collecting blade and avoiding the accumulation of excessive impurities on the side of the collecting blade, which affects the compression and gas transmission efficiency of the equipment.

[0018] (2) The present invention solves the problem that high-pressure gas always flows toward low-pressure gas. By utilizing the characteristic of the regular movement of the push rod, the air inlet frame is arranged at the bottom of the air inlet housing. When the cross space of the collecting blades deflects upward due to rotation, the air inlet frame is formed as follows: Figure 4 In this state, the space between the collecting blades and the inner wall of the air inlet shell form a sealed space. At this time, the sliding wheel is restricted by the inclined surface of the inclined panel. When the sliding wheel reaches the top of the outer wall of the inclined panel, the pushing rod penetrates into the interior of the air inlet shell and pushes the air in the sealed space into the interior of the boosting spiral blades, while the high-pressure gas inside the boosting spiral blades is discharged from the outlet of the support frame, avoiding the problem of low boosting efficiency caused by the high pressure inside the boosting spiral blades affecting the entry of the collecting blade air.

[0019] (3) The present invention utilizes the centrifugal force generated by the rotation of the power gear. When the push plate rotates following the power gear, the centrifugal force forces the cleaning rod to extend outward along the outer wall of the push plate. During this process, the cleaning rod will scratch the outer wall of the push plate. After the equipment completes the processing and stops, the reset spring will release the accumulated mechanical power, driving the cleaning rod to reset and clean the outer wall of the push plate again, thereby preventing paint particles from adhering to the outer wall of the push plate and affecting the airtightness during the pressurization process of the equipment.

[0020] (4) In order to solve the clogging problem of the air inlet frame during operation, the present invention provides a scratch frame inside the equipment. When the driving rod rotates, the driving belt drives the driving wheel to rotate, and the driving wheel drives the water-displacing fan blades to rotate, forcing the liquid inside the boost pipe to rotate. The force generated by the water flow will force the sealing plate to push the sliding rod to move outward, and the scratch frame will move sideways along the inner wall of the air inlet frame. After the equipment completes the processing, the thrust inside the boost pipe disappears, and the extrusion spring releases the accumulated mechanical power to drive the scratch frame to reset. During the reset process, the scratch frame will scrape off the impurities adhering to the surface of the air inlet frame, ensuring that external impurities will not affect the air intake of the air inlet frame during subsequent processing.

[0038] For example 2, please refer to Figure 4 - Figure 8 The present invention is an outer rotor spiral blade conical booster fan. On the basis of Example 1, the pressurizing mechanism 2 also includes a booster spiral blade 204 fixedly connected to the outer wall of the driving rod 203, a collecting blade 205 fixedly connected to the outer wall of the driving rod 203, a push rod 206 slidably connected to the inner wall of the through hole on the sliding circular plate 202, a sliding wheel 207 rotatably connected to the side wall of the push rod 206, a push plate 208 fixedly connected to the end of the push rod 206 away from the sliding wheel 207, the side wall of the push plate 208 is slidably connected to the side wall of the collecting blade 205, a push spring 212 is sleeved on the outer wall of the push rod 206, and a push spring 212 is sleeved on the outer wall of the push rod 206. The inclined surface presented by the panel 104, after the power supply of the electric motor 105 is turned on, the electric motor 105 drives the power gear 201 to rotate through the driving gear 106, and the power gear 201 drives the booster spiral blade 204 to pressurize and discharge the external air through the driving rod 203. In addition, when the power gear 201 and the power gear 201 rotate, the sliding wheel 207 is restricted by the inclined surface of the air inlet frame 107, forcing the push plate 208 to be pushed outward along the outer wall of the collecting blade 205, so as to clean the side of the collecting blade 205 and avoid the accumulation of too many impurities on the side of the collecting blade 205, which affects the compression and gas transmission efficiency of the equipment.

[0039] The pressurizing mechanism 2 also includes a cleaning ring 209 fixedly connected to the side wall of the push plate 208, a return spring 210 fixedly connected to the inner wall of the cleaning ring 209, and a cleaning rod 211 fixedly connected to the end of the return spring 210 away from the collecting blade 205. The side wall of the cleaning rod 211 is slidably connected to the side wall of the push plate 208. In order to solve the problem that high-pressure gas always flows to low-pressure gas, the push rod 206 is used to regularly move, and the air inlet frame 107 is set at the bottom of the air inlet housing 101. When the cross space of the collecting blade 205 is deflected upward due to rotation, it presents as shown in the figure. Figure 4In this state, the space between the collecting blades 205 and the inner wall of the air inlet shell 101 forms a sealed space. At this time, the sliding wheel 207 is restricted by the inclined surface of the inclined panel 104. When the sliding wheel 207 reaches the top of the outer wall of the inclined panel 104, the pushing rod 206 penetrates into the interior of the air inlet shell 101 and pushes the air in the sealed space into the interior of the boosting spiral blades 204, and the high-pressure gas inside the boosting spiral blades 204 is discharged from the outlet of the support frame 109, avoiding the problem of low boosting efficiency caused by the high pressure inside the boosting spiral blades 204 affecting the entry of air into the collecting blades 205.

[0040] The cleaning mechanism 3 also includes a scratch frame 304 fixedly connected to the side wall of the sliding rod 301, the outer wall of the scratch frame 304 is slidably connected to the inner wall of the air inlet frame 107, a fixed block 305 is fixedly connected to the top of the equipment base 111, a boost pipe 306 is fixedly connected to the top of the fixed block 305, the inner wall of the boost pipe 306 is slidably connected to the outer wall of the sealing plate 302, and the centrifugal force generated by the rotation of the power gear 201 is utilized. When the push plate 208 rotates following the power gear 201, the centrifugal force forces the cleaning rod 211 to extend outward along the outer wall of the push plate 208. During this process, the cleaning rod 211 will scratch the outer wall of the push plate 208. After the equipment completes the processing and stops, the reset spring 210 will release the accumulated mechanical power, drive the cleaning rod 211 to reset, and clean the outer wall of the push plate 208 again to avoid paint particles adhering to the outer wall of the push plate 208, which affects the airtightness during the equipment pressurization process.

[0041] The cleaning mechanism 3 also includes a rotating column 307 rotatably connected to the inner wall of the through hole on the surface of the boost pipe 306, a driving wheel 308 is fixedly connected to the side wall of the rotating column 307, a driving belt 309 is sleeved on the outer wall of the driving wheel 308, and the end of the driving belt 309 away from the driving wheel 308 is rotatably connected to the outer wall of the driving rod 203, and the end of the rotating column 307 away from the driving wheel 308 is fixedly connected to the water-repelling fan blade 310. In order to solve the clogging problem of the air inlet frame 107 when working, a scratch frame 304 is arranged inside the device. When the driving rod 203 rotates, the driving wheel 308 is driven by the driving belt 309 to The driving wheel 308 drives the water-repelling blades 310 to rotate, forcing the liquid inside the boost pipe 306 to rotate, and the force generated by the water flow will force the sealing plate 302 to push the sliding rod 301 to move outward, and the scratch frame 304 moves sideways along the inner wall of the air inlet frame 107. After the equipment completes the processing, the internal thrust of the boost pipe 306 disappears, and the extrusion spring 303 releases the accumulated mechanical power, driving the scratch frame 304 to reset, and during the resetting process, the scratch frame 304 will scrape off the impurities stuck to the surface of the air inlet frame 107, to ensure that during subsequent processing, external impurities will not affect the air intake of the air inlet frame 107.

[0042] The manufacturing method of the manufacturing device comprises the following steps:

[0043] S1: The device utilizes the inclined surface presented by the inclined plate 104. After the power of the electric motor 105 is turned on, the electric motor 105 drives the power gear 201 to rotate through the driving gear 106.

[0044] S2: When the intersection space of the collecting blades 205 is deflected upward due to rotation, the space between the collecting blades 205 and the inner wall of the air inlet shell 101 form a sealed space, pushing the rod 206 to penetrate into the interior of the air inlet shell 101 and push the air in the sealed space into the interior of the boosting spiral blades 204.

[0045] S3: Centrifugal force forces the cleaning rod 211 to extend outward along the outer wall of the push plate 208. During this process, the cleaning rod 211 will scrape the outer wall of the push plate 208. After the equipment completes the processing, the reset spring 210 will release the accumulated mechanical power to drive the cleaning rod 211 to reset.

[0046] A specific application of this embodiment is: the present invention utilizes the inclined surface presented by the inclined plate 104. After the power supply of the electric motor 105 is turned on, the electric motor 105 drives the power gear 201 to rotate through the driving gear 106, and the power gear 201 drives the booster spiral blade 204 to pressurize and discharge the external air through the driving rod 203. In addition, when the power gear 201 and the power gear 201 rotate, the sliding wheel 207 is restricted by the inclined surface of the air inlet frame 107, forcing the push plate 208 to be pushed outward along the outer wall of the collecting blade 205 to achieve cleaning of the side of the collecting blade 205. In view of the problem that high-pressure gas always flows to low-pressure gas, the air inlet frame 107 is set at the bottom of the air inlet shell 101 by utilizing the characteristic of the regular movement of the push rod 206. When the cross space of the collecting blade 205 is deflected upward due to rotation, it presents as shown below. Figure 4The state is obtained, and the space between the collecting blades 205 and the inner wall of the air inlet housing 101 form a sealed space. At this time, the sliding wheel 207 is restricted by the inclined surface of the inclined plate 104. When the sliding wheel 207 reaches the top of the outer wall of the inclined plate 104, the pushing rod 206 penetrates into the interior of the air inlet housing 101 and pushes the air in the sealed space into the interior of the supercharged spiral blade 204, and the high-pressure gas inside the supercharged spiral blade 204 is discharged from the outlet of the support frame 109. The centrifugal force generated by the rotation of the power gear 201 is utilized. When the pushing plate 208 rotates following the power gear 201, the centrifugal force forces the cleaning rod 211 to extend outward along the outer wall of the pushing plate 208. In this process, the cleaning rod 211 will scrape the outer wall of the pushing plate 208. After the equipment completes the processing and stops, the return spring 210 will release the accumulated mechanical power to drive the cleaning rod 211 to return to the original position. The outer wall of the push plate 208 is cleaned again. In order to solve the blockage problem of the air inlet frame 107 during operation, a scratch frame 304 is arranged inside the equipment. When the driving rod 203 rotates, the driving belt 309 drives the driving wheel 308 to rotate, and the driving wheel 308 drives the water-repelling fan blade 310 to rotate, forcing the liquid inside the boost pipe 306 to rotate. The force generated by the water flow will force the sealing plate 302 to push the sliding rod 301 to move outward, and the scratch frame 304 moves sideways along the inner wall of the air inlet frame 107. After the equipment completes the processing, the internal thrust of the boost pipe 306 disappears, and the extrusion spring 303 releases the accumulated mechanical power to drive the scratch frame 304 to reset. During the resetting process, the scratch frame 304 will scrape off the impurities adhering to the surface of the air inlet frame 107 to ensure that external impurities will not affect the air intake of the air inlet frame 107 during subsequent processing.
