Description

Technical Field

[0001] This invention relates to the field of electric motors, and more particularly to a highly reliable three-phase energy-saving asynchronous motor. Background Technology

[0002] Three-phase asynchronous motors are among the most widely used drive devices in the industrial field, and their operational reliability directly affects production efficiency and equipment lifespan. During continuous operation of the motor, in order to ensure the effectiveness of the internal cooling system, a filter screen is usually installed at the air inlet to prevent dust, fibers, and other particulate matter from entering the motor.

[0003] In traditional three-phase asynchronous motors, dust accumulation on the filter screen can significantly increase ventilation resistance during long-term use, leading to abnormal motor temperature rise, decreased efficiency, and even winding burnout. Current technologies often employ periodic manual disassembly and cleaning or external air source backflushing for maintenance. However, manual maintenance suffers from poor timeliness, while external air source backflushing devices are limited in application scenarios due to their complex structure and reliance on external air sources, making them unsuitable for continuous production. Therefore, finding solutions to these problems is essential. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly reliable three-phase energy-saving asynchronous motor. This motor can perform self-cleaning on the filter screen after each use, ensuring its continuous usability. In addition, the self-cleaning part adopts a triple cleaning method of centrifugation, backflushing, and vibration, which achieves better cleaning effect.

[0006] Preferably, a sealing circular plate is fixedly connected to the inner wall of the heat dissipation cylinder, and four strip-shaped ventilation holes are equally spaced on the sealing circular plate. A rotating ring is horizontally arranged through the sealing circular plate, and the rotating ring is rotatably connected to the sealing circular plate through a bearing. The drive shaft passes through the rotating ring, and an electromagnet is embedded in the inner side of the rotating ring.

[0007] Preferably, four L-shaped connecting plates are fixedly connected at equal intervals on the outer side of the rotating ring, and a sealing plate is fixedly connected to the other side of each L-shaped connecting plate. A torsion spring is fixedly connected to the outer side of the rotating ring, and the other end of the torsion spring is fixedly connected to the right side of the sealing plate.

[0008] Preferably, the driving mechanism includes a rotating disk fixedly connected to the right end of the driving shaft, a piston cylinder fixedly connected to the bottom of the heat sink, a second piston plate that can slide up and down inside the piston cylinder, a driving rod rotatably connected to the upper end of the second piston plate, and the other end of the driving rod rotatably connected to the right eccentric part of the rotating disk.

[0009] Preferably, the piston cylinder has a one-way port at its inner bottom, and the inner bottom space of the piston cylinder is connected to the inner top space of the temporary storage cylinder through a one-way tube. The temporary storage cylinder has a first piston plate that can slide up and down. The lower end of the first piston plate is elastically connected to the inner bottom of the temporary storage cylinder through a first spring. One-way valves are installed inside both the one-way port and the one-way tube. The flow direction of the one-way valve inside the one-way port is one-way from the outside to the inner bottom space of the piston cylinder. The flow direction of the one-way valve inside the one-way tube is one-way from the piston cylinder to the inner top space of the temporary storage cylinder. An opening is provided on the right side wall of the inner bottom space of the temporary storage cylinder. The diameter of the opening is larger than the thickness of the first piston plate. An axial flow fan is provided inside the rotating tube. The outer side of the axial flow fan is fixedly connected to the inner side of the rotating tube.

[0010] Preferably, a normally open solenoid valve is installed inside the exhaust pipe, and the normally open solenoid valve, the electromagnet, and the motor body open and close synchronously.

[0011] Preferably, the auxiliary mechanism includes a fixed ring fixedly connected to the outside of the annular filter screen, a plurality of wedge-shaped blocks fixedly connected at equal intervals on the right side of the fixed ring, a sliding cylinder fixedly connected to the front side of the protective cylinder, a piston column that can slide left and right inside the sliding cylinder, a sliding cavity inside the piston column, a sliding plate that can slide left and right inside the sliding cavity, the right side of the sliding plate being elastically connected to the right side wall of the sliding cavity via a second spring, the right side of the piston column being elastically connected to the right side wall of the sliding cavity via a third spring, an exhaust vent being opened on the front side of the right side space of the sliding cavity, an impact column fixedly connected to the left side of the sliding plate, the left end of the impact column penetrating the left side inner wall of the sliding cavity, and the right side space of the sliding cylinder being connected to the exhaust pipe via a branch pipe.

[0012] Preferably, the left end of the impact post is rounded and cooperates with multiple wedge blocks, and a brush strip is fixedly connected to the rear side of the impact post.

[0013] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Under normal conditions, the sealing plate seals the strip-shaped ventilation opening, preventing dust and other impurities from entering the motor and protecting the internal components. When the motor starts and the electromagnet is energized, the sealing plate opens the ventilation opening, forming an efficient cooling airflow with the fan blades and heat dissipation holes, ensuring stable motor operation.

[0014] 2. The reciprocating motion of the second piston plate, driven by the drive mechanism, stores external gas in a temporary storage cylinder, providing a stable gas source for subsequent cleaning. When the motor stops, the normally open solenoid valve is turned on, releasing the gas in the temporary storage cylinder. A portion of the gas drives the rotating tube and the annular filter screen to rotate, using centrifugal force for initial cleaning.

[0015] 3. With multiple strip ventilation openings sealed, rotating the pipe to inject gas can achieve gas backflushing, blowing dust away from the filter screen, avoiding secondary adhesion, and greatly improving the cleaning effect.

[0016] 4. A portion of the high-pressure gas enters the sliding cylinder, causing the piston to move. The impact column strikes the fixed ring, generating vibration, which helps to loosen the tightly adhered dust on the annular filter screen. This, combined with centrifugal cleaning, further enhances the cleaning power and effectively removes stubborn dust from the filter screen.

[0017] 5. The reciprocating motion of the impact column drives the brush strip to rotate and brush the rotating annular filter screen from side to side, cleaning the filter screen surface in multiple dimensions, improving the brushing cleaning effect, ensuring that the annular filter screen maintains good filtration performance, and maintaining efficient heat dissipation of the motor.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Reference Figures 1-8 A high-reliability three-phase energy-saving asynchronous motor includes a motor body 1. A heat sink 2 is fixedly connected to the right side of the motor body 1. A protective cylinder 6 is provided to the right side of the heat sink 2. The right end of the protective cylinder 6 is sealed. The heat sink 2 and the protective cylinder 6 are fixedly connected by two U-shaped connecting plates 10. An annular groove 11 is provided on the outer side of the heat sink 2 and the protective cylinder 6. An annular filter screen 8 is provided in the annular groove 11. A drive shaft 19 is installed inside the motor body 1. When the motor body 1 is started, the drive shaft 19 will start to rotate. The right end of the drive shaft 19 extends into the heat sink 2 and is fixedly connected to multiple fan blades 29. The airflow generated by the rotation of the multiple fan blades 29 is from right to left. Furthermore, a heat dissipation hole is provided on the left side of the motor body 1 to generate continuous airflow.

[0022] The system also includes a cleaning mechanism for cleaning the protective cylinder 6. The heat dissipation mechanism includes a temporary storage cylinder 3 fixedly connected to the upper end of the heat dissipation cylinder 2. A rotating tube 16 is rotatably connected to the right side wall of the protective cylinder 6. The right end of the rotating tube 16 extends to the outside and is connected to the other end of the rotating tube 16 through a rotary joint 17. The outside of the rotating tube 16 is fixedly connected to the inside of the annular filter screen 8 through multiple fixing rods 36. When the rotating tube 16 rotates, the annular filter screen 8 can be rotated through the fixing rods 36, and the centrifugal force generated by the rotation is used to clean the dust on the outside.

[0023] This includes a sealing circular plate 20 fixedly connected to the inner wall of the heat sink 2. Four strip-shaped ventilation openings 21 are evenly spaced on the sealing circular plate 20. A rotating ring 28 is horizontally inserted through the sealing circular plate 20 and is rotatably connected to the sealing circular plate 20 via a bearing. A drive shaft 19 passes through the rotating ring 28. An electromagnet is embedded inside the rotating ring 28. Four L-shaped connecting plates 26 are evenly spaced and fixedly connected to the outer side of the rotating ring 28. A sealing plate 27 is fixedly connected to the other side of each L-shaped connecting plate 26. A torsion spring 25 is fixedly connected to the outer side of the rotating ring 28, and the other end of the torsion spring 25 is fixedly connected to the right side of the sealing circular plate 20. Under normal conditions, multiple... The sealing plate 27 seals the multiple strip-shaped ventilation openings 21. When the subsequent drive shaft 19 is started and the electromagnet is also energized, the rotation of the iron alloy drive shaft 19 will drive the rotating ring 28 to rotate, and cause the torsion spring 25 to be contracted. After the torsion spring 25 can no longer be contracted, the rotating ring 28 will no longer rotate with the rotation of the drive shaft 19. At this time, the multiple sealing plates 27 will be in a state of not blocking the multiple strip-shaped ventilation openings 21 as the L-shaped connecting plate 26 rotates. When the subsequent motor body 1 is not working, the electromagnet is de-energized, and under the elastic action of the torsion spring 25, the multiple sealing plates 27 will return to their original positions, thus sealing the multiple strip-shaped ventilation openings 21.

[0024] The system also includes a drive mechanism for operating the cleaning mechanism. The drive mechanism includes a rotating disk 22 fixedly connected to the right end of the drive shaft 19. A piston cylinder 14 is fixedly connected to the bottom inner part of the heat sink 2. A second piston plate 24, which can slide up and down, is provided inside the piston cylinder 14. A drive rod 23 is rotatably connected to the upper end of the second piston plate 24. The other end of the drive rod 23 is rotatably connected to the right eccentric part of the rotating disk 22. A one-way port 15 is provided at the bottom inner part of the piston cylinder 14. The bottom inner space of the piston cylinder 14 is connected to the top inner space of the temporary storage cylinder 3 through a one-way pipe 4. A first piston plate 12, which can slide up and down, is provided inside the temporary storage cylinder 3. The lower end of the first piston plate 12 is elastically connected to the bottom inner part of the temporary storage cylinder 3 through a first spring 13. One-way valves are installed inside both the one-way port 15 and the one-way pipe 4. The flow direction of the one-way valve inside the one-way port 15 is one-way from the outside into the bottom inner space of the piston cylinder 14. The flow direction of the gas into the one-way valve inside the pipe 4 is one-way into the top space of the storage cylinder 3 via the piston cylinder 14. As the second piston plate 24 moves up and down, a one-way airflow can be generated between the outside, the piston cylinder 14, and the top space of the storage cylinder 3. This one-way airflow allows the gas stored in the storage cylinder 3. An opening is provided on the right side wall of the bottom space inside the storage cylinder 3. The diameter of the opening is larger than the thickness of the first piston plate 12. This method ensures that the first piston plate 12 will not continue to move down when it reaches the opening. An axial flow fan 39 is provided inside the rotating pipe 16. The outer side of the axial flow fan 39 is fixedly connected to the inner side of the rotating pipe 16. A normally open solenoid is installed inside the exhaust pipe 5. The normally open solenoid valve, the electromagnet, and the motor body 1 open and close synchronously. When the gas in the storage cylinder 3 is released, part of it enters the rotating pipe 16. After passing through the axial flow fan 39, it drives the rotating pipe 16 to rotate. The other part enters the right space of the sliding cylinder 7.

[0025] This also includes an auxiliary mechanism that works in conjunction with the cleaning mechanism to improve the cleaning effect. The auxiliary mechanism includes a fixing ring 9 fixedly connected to the outside of the annular filter screen 8. Multiple wedge-shaped blocks 37 are fixedly connected at equal intervals to the right side of the fixing ring 9. The multiple wedge-shaped blocks 37 are as follows: Figure 7As shown, as the annular filter 8 rotates, the impact column 30 initially contacts the right side of the fixed ring 9, then contacts the inclined surface of the wedge block 37, then the plane, and after passing the plane, it directly impacts the fixed ring 9 under the elastic action of the second spring 34. This method utilizes the vibration generated by the impact to remove dust from the annular filter 8. Combined with its own rotational centrifugal force, it further promotes the removal of dust from the annular filter 8. A sliding cylinder 7 is fixedly connected to the front side of the protective cylinder 6. A piston column 32 that can slide left and right is provided inside the sliding cylinder 7. A sliding cavity is provided inside the piston column 32. A sliding plate 33 that can slide left and right is provided inside the sliding cavity. The right side of the sliding plate 33 is elastically connected to the right side wall of the sliding cavity through the second spring 34. The right side of the piston column 32 is elastically connected to the right side wall of the sliding cavity through the third spring 35. An exhaust vent 38 is opened on the front side of the right space of the sliding cavity. The exhaust vent 38 here is small, so as a large amount of high pressure enters through the branch pipe 18, After the gas is released, the gas in the right space of the sliding cylinder 7 will increase rapidly (the gas released from the exhaust vent 38 is slower), thereby increasing the gas pressure in the right space of the sliding cylinder 7. This causes the piston rod 32 to move to the left limit position (i.e., the impact rod 30 contacts the right side of the fixing ring 9). The impact rod 30 is fixedly connected to the left side of the sliding plate 33. The left end of the impact rod 30 penetrates the left inner wall of the sliding cavity. An L-shaped guide strip is fixedly connected to the upper end of the impact rod 30. A guide groove is opened on the left side of the sliding cylinder 7. The horizontal part of the L-shaped guide strip extends into the guide groove and is slidably connected. The right space of the sliding cylinder 7 is connected to the exhaust pipe 5 through the branch pipe 18. The left end of the impact rod 30 is round and cooperates with multiple wedge blocks 37. A brush strip 31 is fixedly connected to the rear side of the impact rod 30. It should be noted that during the left and right movement of the impact rod 30, the brush strip 31 will also move left and right, which will perform relative rotation and relative left and right brushing on the rotating annular filter screen 8, improving the brushing cleaning effect.

[0026] In this invention, under normal conditions, multiple sealing plates 27 seal multiple strip-shaped ventilation openings 21. After the motor body 1 starts, when the drive shaft 19 starts and the electromagnet is energized, the iron alloy drive shaft 19 rotates, driving the rotating ring 28 to rotate, and the torsion spring 25 is contracted. When the torsion spring 25 can no longer contract, that is, after reaching the contraction limit position, the rotating ring 28 no longer rotates with the drive shaft 19. At this time, the multiple sealing plates 27 rotate with the L-shaped connecting plate 26 and are in a state where they do not block the multiple strip-shaped ventilation openings 21. The drive shaft 19 starts to rotate, and the multiple fan blades 29, which extend to the inside of the heat dissipation cylinder 2 and are fixedly connected at their right end, rotate accordingly, generating airflow from right to left. At the same time, the heat dissipation holes provided on the left side of the motor body 1 generate continuous airflow, realizing basic heat dissipation of the motor. In this airflow, dust will be intercepted on the outside of the annular filter screen 8. The rotating disk 22, which is fixedly connected to the right end of the drive shaft 19, rotates with the rotation of the drive shaft 19, driving the drive rod 23, which is eccentrically connected to the right side of the rotating disk 22, to move. The other end of the drive rod 23 is rotatably connected to the second piston plate 24, which can slide up and down inside the bottom piston cylinder 14 of the heat sink 2. As the second piston plate 24 moves up and down, the outside gas enters the bottom space of the piston cylinder 14 through the one-way port 15 (with an internal one-way valve that allows the outside to enter the bottom space of the piston cylinder 14 in one direction) and then enters the top space of the temporary storage cylinder 3 through the one-way pipe 4 (with an internal one-way valve that allows the piston cylinder 14 to enter the top space of the temporary storage cylinder 3 in one direction), so that the temporary storage cylinder 3 stores gas, causing the first piston plate 12 to move down and compress the first spring 13. When the motor body 1 is not working, the electromagnet is de-energized. Under the elastic action of the torsion spring 25, multiple sealing plates 27 return to their original positions and reseal multiple strip-shaped ventilation openings 21. At the same time, the normally open solenoid valve is de-energized and conducts, releasing the gas in the storage cylinder 3. A portion of the gas enters the rotating tube 16 and passes through the axial flow fan 39 (the outer side of the axial flow fan 39 is fixedly connected to the inner side of the rotating tube 16). When the airflow passes through the axial flow fan 39, the torque force generated by the airflow passing through the fan blades will cause the fan blades to rotate, and at the same time drive the rotating tube 16 fixedly connected to it to rotate. The rotation direction of the rotating tube 16 is counterclockwise from the right to the left. The outer side of the rotating tube 16 is fixedly connected to the inner side of the annular filter screen 8 by multiple fixing rods 36. The annular filter screen 8 is in contact with and slidably connected to the annular groove 11. Therefore, the rotation of the rotating tube 16 can cause the annular filter screen 8 to rotate by using the fixing rods 36. The centrifugal force generated by the rotation cleans the dust on the outer side of the annular filter screen 8. After the gas enters the protective cylinder 6 through the rotating tube 16, the gas will be blown from the inner side to the outer side of the annular filter screen 8 because the multiple strip-shaped vents 21 are sealed at this time, thus achieving gas backflushing. This backflushing not only has a cleaning effect, but also blows the cleaned dust away from the annular filter screen 8, avoiding secondary dust adhesion.

[0027] Another portion of the gas enters the branch pipe 18. When a large amount of high-pressure gas enters the branch pipe 18, the gas in the space on the right side of the sliding cylinder 7 increases rapidly. Because the exhaust vent 38 releases gas slowly, the gas pressure in the right space increases, causing the piston rod 32 to move to the left to its extreme position (the impact rod 30 contacts the right side of the fixed ring 9). As the annular filter screen 8 rotates, the impact rod 30 initially contacts the right side of the fixed ring 9, then contacts the inclined surface of the wedge block 37, and then the plane. After passing the plane, it impacts the fixed ring 9 under the elastic action of the second spring 34, generating vibration and causing the dust on the annular filter screen 8 to fall off. During the above process, the impact column 30 will move back and forth left and right. During the left and right movement of the impact column 30, it will drive the brush strip 31 to move left and right, which will perform relative rotation and relative left and right brushing on the rotating annular filter screen 8, improve the brushing cleaning effect, and complete the overall self-cleaning.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
