Description

Technical Field

[0001] The present invention relates to the technical field of fans, and specifically to a metal energy-saving axial flow compressor fan. Background Art

[0002] As the core equipment of the industrial ventilation system, the performance of the axial flow compressor fan directly affects the energy utilization efficiency and operating cost. With the continuous improvement of the requirements for energy conservation and consumption reduction in the industrial field, the research and development of metal energy-saving axial flow compressor fans has become the focus of the industry. The impeller angle of conventional axial flow fans is fixed and it is difficult to dynamically adapt to complex working conditions, resulting in a significant reduction in operating efficiency under off-design conditions. Axial flow compressor fans are required in engineering ventilation systems.

[0003] When existing fans are in use, especially in an environment with a relatively high ambient temperature, there is no heat insulation measure in the inner cylinder of the fan. During long-term use, heat circulation is likely to occur, causing the temperature of the motor to continuously rise and the motor to easily malfunction. To solve the above problems, reference can be made to the high-temperature resistant axial flow fan disclosed in the prior art (Chinese Patent with Application No. CN201220213276.4 and Publication Date of March 20, 2013). Since this fan adopts a cold air circulation cooling form and is wrapped with heat insulation materials on the outside, it ensures that the motor in the inner cylinder is not affected by the ambient circulating heat; it adopts a separable inner cylinder structure, reducing the working intensity during motor maintenance and replacement and increasing the service life of the motor. This utility model has a simple structure, obvious cooling effect, and increases the service life of the fan. Reference can also be made to a kind of axial flow smoke exhaust fan with a cooling structure disclosed in the prior art (Chinese Patent with Application No. CN202320805230.X and Publication Date of February 27, 2024). In this fan, an arched seat is arranged inside the fan barrel, the motor is arranged on the surface of the arched seat, the end face of the driving shaft of the motor is provided with a first fan blade, a blowing cooling pipe is arranged at the lower end of the fan barrel, a support seat is arranged inside the blowing cooling pipe, a rotating shaft is arranged inside the support seat, a second fan blade is arranged on one side of the rotating shaft, and a transmission rod is arranged at the inner end of the fan barrel. By setting the transmission rod, the second fan blade is driven to blow cooling air flow from the outside, which can effectively cool and lower the temperature of the motor. Finally, reference can be made to the temperature-reducing axial flow fan disclosed in the prior art (Chinese Patent with Application No. CN201620414837.5 and Publication Date of September 21, 2016), including a motor, a rotor, a wind wheel, blades and a cover body. A rotor is arranged at the top of the motor, the rotor is placed inside the wind wheel, blades are fixedly connected to the outer wall of the wind wheel, both the motor and the wind wheel are placed inside the cover body, a cooling pipe is fixedly connected inside the cover body, the cooling pipe is in contact with the motor, the cooling pipe is communicated with a pump body, and liquid nitrogen is arranged inside the cooling pipe, which can increase the cooling effect on the motor, increase the service life, save costs, and improve the efficiency.

[0004] Although the above-mentioned prior art solves the above problems, there are still certain deficiencies in the use of axial flow blowers. When the axial flow blower is working, since the blown air is scattered in one direction, part of the wind power is lost, resulting in low efficiency during use.

[0005] Therefore, we propose a metal energy-saving axial flow blower to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a metal energy-saving axial flow blower to solve the problem that when the axial flow blower on the current market is working, since the blown air is scattered in one direction, part of the wind power is lost, resulting in low efficiency during use as mentioned in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: A metal energy-saving axial flow blower includes a support base and a fixed half cylinder fixed on the top of the support base. The rear side of the fixed half cylinder is connected to one side of the mating half cylinder through a hinge. An air inlet is provided on the left side of the fixed half cylinder and the mating half cylinder, and an air outlet is provided on the right side of the fixed half cylinder and the mating half cylinder; A drive motor is fixed on the bracket on the left side inside the support base. The output end of the drive motor is fixed with a rotating fan blade and a compensation fan blade. The size of the rotating fan blade is larger than that of the compensation fan blade. In addition, a closable closing plate is provided inside the air outlet to enable the air flow to flow into the connecting pipe. One end of the connecting pipe acts on the outside of the cleaning mechanism, and the cleaning mechanism is provided to clean the dust on the surface of the air intake net.

[0008] Preferably, the inside of the compensation fan blade includes a rotating worm gear rotatably connected to the outside of the compensation fan blade. The outside of the rotating worm gear is meshed with the outside of the mating worm wheel. A plurality of groups of connecting teeth are fixedly arranged at equal angles with respect to the center of the mating worm wheel on the surface of the mating worm wheel, and the outside of the connecting teeth is meshed with the outside of the mating gear. The outer end of the center of the mating gear is fixed at the bottom of the fan blade body.

[0009] Preferably, the outside of the fan blade body is rotatably arranged on the outside of the surface of the compensation fan blade, and the rotation range of the fan blade body is -30° to 30°. Through multi-angle adjustment and use, more sufficient compensation can be performed on the rotating fan blade.

[0010] Preferably, the centers of the rotating fan blade, the compensation fan blade, and the output end of the drive motor are collinear. The mating worm wheel is rotatably arranged inside the compensation fan blade. Therefore, through the setting of the compensation fan blade, the wind power generated by the rotating fan blade can be pushed.

[0011] Preferably, the cleaning mechanism includes a connecting pipe connected to one side of the air outlet. The left end of the connecting pipe extends into the inner side of the air inlet, and the left end of the connecting pipe is connected to the end of a matching pipe. The outer end of the matching pipe is slidably arranged inside a fixed rod, and the inner side of the fixed rod and the end of the matching pipe are connected by a connecting spring. In addition, the outer end of the fixed rod is fixed to one side of the air intake net. A number of pressure jet nozzles are fixed at the outer end of the fixed rod. Through the setting of the cleaning mechanism, the impurities remaining on the surface of the air intake net can be cleaned.

[0012] Preferably, the center position of the air intake net is slidably penetrated outside the fixed sliding rod, and the outer wall of the air intake net is slidably arranged inside the air inlet. The end of the fixed sliding rod away from the air intake net is fixed to the bracket fixed by the driving motor. One end of the matching spring is fixed to the outer side of the fixed sliding rod, and the other end of the matching spring is fixed to one side of the air intake net. Thus, the air intake net can move back and forth at the air inlet position, which is convenient for cleaning.

[0013] Preferably, the inside of the matching pipe includes a piston block fitted inside the fixed rod. A conical block is closely fitted inside the piston block. One end of the conical block close to the inside of the matching pipe is fixedly connected to one end of a return spring, and the other end of the return spring is fixed inside a cavity opened in the matching pipe. This enables the matching pipe to drive the fixed rod to move first, and then the pressure jet nozzles are used for pressure relief.

[0014] Preferably, the elastic force of the return spring is greater than that of the connecting spring, and the search conical block forms a sliding structure with the inside of the piston block through the return spring. In addition, the cavity is communicated with the inside of the connecting pipe.

[0015] Preferably, a number of groups of the pressure jet nozzles are equidistantly arranged around the center of the fixed rod, and the jet direction of the pressure jet nozzles faces the inner side of the air intake net. The air intake net forms a sliding structure with the inside of the air inlet through the fixed rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The metal energy-saving axial flow blower is provided with a rotating fan blade and a compensating fan blade. By rotating the angle of the adjustable fan body on the outer surface of the compensating fan blade, the scattered air flow can be transported more stably. Thus, the air flow at the air inlet can be compensated. And through the arranged connecting pipe, the air intake net can have a slight jitter, and the redundant gas can be discharged through the pressure jet nozzles to clean the shaken-off dust. The specific content is as follows: 1. A compensation fan blade is provided. By rotating the worm, the mating worm gear rotates inside the compensation fan blade, enabling the connecting tooth block to drive the mating gear engaged therewith to rotate, and further enabling the fan blade body to adjust the angle outside the compensation fan blade. Thus, the air flow generated at the air inlet can be compensated according to actual needs.

[0017] 2. A connecting pipe is provided. By closing the closing plate and the air outlet and starting the driving motor, the air flow is transported through the connecting pipe, enabling the air flow to drive the fixing rod to move through the mating pipe. Then, the fixing rod drives the air inlet net to move. After moving to the maximum position, the gas is relieved through the pressure jet nozzle, so as to vibrate the dust on the surface of the air inlet net. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 10 , the present invention provides the following technical solutions: Embodiment

[0022] In order to solve the problem that when the axial flow blower in the current market is working, since the blown air is scattered in one direction, resulting in loss of some wind power, and at this time, the problem of low efficiency occurs during use, reference can be made to the attached Figure 1 - attached Figure 6 , including a support base 1 and a fixed semi-cylinder 2 fixed on the top of the support base 1. The rear side of the fixed semi-cylinder 2 is connected to one side of the mating semi-cylinder 3 through a hinge. An air inlet 4 is provided on the left side of the fixed semi-cylinder 2 and the mating semi-cylinder 3, and an air outlet 5 is provided on the right side of the fixed semi-cylinder 2 and the mating semi-cylinder 3; it is characterized in that: a driving motor 7 is fixed on the bracket on the left side inside the support base 1, and a rotating fan blade 8 and a compensation fan blade 9 are fixed on the output end of the driving motor 7. The size of the rotating fan blade 8 is larger than that of the compensation fan blade 9. The inside of the compensation fan blade 9 includes a rotating worm 91 rotatably connected to the outside of the compensation fan blade 9. The outside of the rotating worm 91 is meshed with the outside of the mating worm gear 92. A plurality of groups of connecting tooth blocks 93 are fixed on the surface of the mating worm gear 92 at equal angles with respect to the center of the mating worm gear 92, and the outside of the connecting tooth blocks 93 is meshed with the outside of the mating gear 94. The outer end of the center of the mating gear 94 is fixed at the bottom of the fan blade body 95; the outside of the fan blade body 95 is rotatably arranged on the outside of the surface of the compensation fan blade 9, and the rotation range of the fan blade body 95 is -30° - 30°; the centers of the rotating fan blade 8, the compensation fan blade 9, and the output end of the driving motor 7 are collinear, and the mating worm gear 92 is rotatably arranged inside the compensation fan blade 9.

[0023] First, in order to more conveniently compensate for the wind force generated by the air inlet 4, by rotating and mating with the semi-cylinder 3, one end of the mating semi-cylinder 3 rotates outside the fixed semi-cylinder 2, so that the drive motor 7, the rotating fan blade 8, and the compensation fan blade 9 can be shown. Subsequently, by rotating the rotating worm 91 on one side of the compensation fan blade 9, during the rotation of the rotating worm 91 outside the compensation fan blade 9, it can drive the mating worm wheel 92 connected by meshing to rotate. And a number of groups of connecting tooth blocks 93 are fixed on one side of the surface of the mating worm wheel 92. When the connecting tooth blocks 93 rotate, they can drive the mating gear 94 connected by meshing to rotate inside the compensation fan blade 9. In addition, the center position of the mating gear 94 is fixed at the end of the fan blade body 95, so that the fan blade body 95 can adjust the angle outside the compensation fan blade 9, and all the fan blade bodies 95 rotate synchronously, and the adjusted angles are also the same. When the rotating fan blade 8 rotates, the rotating fan blade 8 will also drive the compensation fan blade 9 to rotate. The air flow generated during the rotation of the rotating fan blade 8 will cross at a point. At this time, the rotation of the compensation fan blade 9 can push the air flow crossing, so that the air flow will be discharged more stably through the air outlet 5. Embodiment

[0024] When this embodiment is different from Embodiment 1, after closing the closing plate 6 and one side of the air inlet 4, through the setting of wind force, the dust inside the air inlet net 14 provided inside the air inlet 4 can be cleaned. Reference can be made to the attached Figure 1 - attached Figure 3 and attached Figure 7 - attached Figure 10, a closing plate 6 that can be closed is arranged inside the air outlet 5 to enable air flow to the inside of the connecting pipe 10. One end of the connecting pipe 10 acts on the outside of the cleaning mechanism, and the cleaning mechanism is arranged to clean the dust on the surface of the air intake net 14; the left end of the connecting pipe 10 extends into the inside of the air inlet 4, and the left end of the connecting pipe 10 is connected to the end of the matching pipe 12. The outer end of the matching pipe 12 is slidably arranged inside the fixed rod 13, and the inner side of the fixed rod 13 is connected to the end of the matching pipe 12 through a connecting spring 131. In addition, the outer end of the fixed rod 13 is fixed to one side of the air intake net 14, and several groups of pressure jet nozzles 15 are fixed at the outer end of the fixed rod 13; the center position of the air intake net 14 penetrates and slides on the outside of the fixed slide rod 16, and the outer wall of the air intake net 14 is slidably arranged inside the air inlet 4. One end of the fixed slide rod 16 away from the air intake net 14 is fixed to the bracket where the drive motor 7 is fixed. The outside of the fixed slide rod 16 is fixed to one end of the matching spring 17, and the other end of the matching spring 17 is fixed to one side of the air intake net 14; the inside of the matching pipe 12 includes a piston block 121 that fits inside the fixed rod 13. A tapered block 122 is closely attached inside the piston block 121. One end of the tapered block 122 close to the inside of the matching pipe 12 is fixedly connected to one end of a return spring 123, and the other end of the return spring 123 is fixed inside a cavity 124 opened in the matching pipe 12; the elastic force of the return spring 123 is greater than the elastic force of the connecting spring 131, and the search tapered block 122 forms a sliding structure with the inside of the piston block 121 through the return spring 123. In addition, the cavity 124 is communicated with the inside of the connecting pipe 10; several groups of pressure jet nozzles 15 are arranged at equal intervals around the center of the fixed rod 13, and the jet direction of the pressure jet nozzles 15 is directed towards the inside of the air intake net 14. The air intake net 14 forms a sliding structure with the inside of the air inlet 4 through the fixed rod 13.

[0025] After closing the closing plate 6 and the air inlet 4, by starting the drive motor 7 to drive the rotating fan blade 8 to rotate, the air flow will not be released. At this time, the shunt will flow through the connecting pipe 10. At this time, the closing valve 11 needs to be opened, so that the gas inside the connecting pipe 10 will be transported to the cavity 124 opened in the matching pipe 12, so that the matching pipe 12 and the fixed rod 13 will be separated. At this time, the fixed rod 13 will also drive the air intake net 14 to slide on the outside of the fixed slide rod 16. In addition, the other end of the fixed slide rod 16 will also drive the matching spring 17 to stretch. When the fixed rod 13 moves to the maximum range, the gas will be released through the pressure jet nozzles 15. In addition, during the pressure relief process, the matching spring 17 will also drive the air intake net 14 to reset. When the air intake net 14 shakes, it will also perform a blowing and cleaning process, so as to achieve the purpose of cleaning the outside of the air intake net 14.

[0026] Although the present invention 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 perform equivalent replacements for some of the technical features.
