Description

Technical Field

[0001] This invention relates to the field of fluid transport technology, specifically to a magnetic pump with a circulating cooling function. Background Technology

[0002] Recirculating cooling magnetic pumps are mostly used in high-risk fluid transportation scenarios with explosion-proof and leakage-proof requirements. They are mainly used to transport corrosive, flammable and explosive media. While preventing media leakage, they can continuously dissipate heat from core heat-generating components, ensuring the safe operation of the equipment. However, existing magnetic pumps generally use independent external cooling pipes and lack a linkage drive structure, which can easily lead to insufficient power in the cooling circuit and interruption of media circulation. They cannot achieve autonomous circulation cooling, which in turn causes internal heat accumulation, resulting in high-temperature aging and damage to components, and a decrease in the stability and service life of the equipment.

[0003] A search revealed Chinese Patent Publication No. CN105065335A, which discloses a cooling structure for a high-temperature magnetic pump. The structure includes blades on the tail end face of an outer magnetic rotor and at least one first exhaust port on the tail end face along the axial direction of the outer magnetic rotor. At least one first air inlet port is provided on the side wall of the outer magnetic rotor. The structure also includes at least one second air inlet port on the side wall of the housing, corresponding to the area of ​​the first air inlet port of the outer magnetic rotor, and at least one second exhaust port on the tail end of the housing side wall, corresponding to the area of ​​the first exhaust port of the outer magnetic rotor. The second air inlet port, first air inlet port, first exhaust port, and second exhaust port are sequentially connected to form an air circulation cooling channel. A magnetic pump with the aforementioned cooling structure is also disclosed. This air circulation cooling structure design can save water resources, reduce operating costs, and allows for simultaneous use of water cooling and air cooling, improving the cooling effect and ensuring service life. However, the above utility model patent has obvious defects. The solution only relies on the external magnetic rotor blades and the air vents of the housing to form an air circulation channel and achieve heat dissipation in a single air-cooling form. The overall heat exchange efficiency is low and it is difficult to solve the heat accumulation problem caused by the high load operation of the equipment. Its cooling area is only concentrated in a local area of ​​the external magnetic rotor and housing, and it cannot dissipate heat to the isolation sleeve, drive motor and other core heat-generating components. There are many heat dissipation blind spots inside the pump body, and the exposed air vents are easily blocked by dust and impurities. Long-term use will cause the cooling channel to fail and the cooling medium cannot circulate autonomously. The cooling capacity is insufficient under high temperature and high-risk medium transportation conditions, and it is difficult to ensure the long-term stable operation of the equipment. Summary of the Invention

[0025] This invention provides a magnetic pump with a circulating cooling function. It has the following beneficial effects: 1. This invention drives the entire machine to operate through a dual-end motor, while the heat dissipation fins on the outer wall expand the heat dissipation area to achieve basic heat dissipation. The jacket of the isolation sleeve and the annular cooling channel form a through-type liquid cooling channel. At the same time, the dual-end motor drives the magnetic rotor and the toggle cam to rotate, and drives the vortex fan blades to rotate through intermittent meshing gears, promoting the unidirectional circulation of the cooling medium. Relying on mechanical linkage, autonomous circulation cooling is achieved, which can efficiently remove the heat accumulated inside the equipment, avoid high-temperature aging and damage of components, and effectively improve the operational stability and service life of the magnetic pump.

[0026] 2. This invention uses a transmission rod to drive a cooling fan and force-cool the refrigerant in the rear of the motor and the annular cooling channel. The dustproof heat dissipation shell can block dust and protect internal components. The lever intermittently moves the swing blades, which, together with the torsion spring, make the blades swing back and forth. The limit post limits the swing amplitude. The blades continuously disturb the airflow and blow on the heat dissipation fins, thus cooling the medium in the annular cooling channel a second time. It operates on its own power without the need for additional drive, has a wider heat dissipation coverage, can effectively suppress temperature rise, ensure the long-term stable operation of the cooling system, and extend the service life of the whole machine.

[0027] 3. This invention breaks the laminar flow state of the cooling medium by using the turbulence cone and flow divider on the outside of the support column, increasing the contact area and improving the heat exchange efficiency. The transmission rod drives the pressure wheel to rotate synchronously, and its internal guide groove, together with the guide plate, guides and pressurizes the medium, accelerates the circulation speed, avoids local heat accumulation inside, requires no additional power, has uniform heat dissipation and stable performance, can effectively reduce the operating temperature of the motor, reduce high-temperature wear of parts, and further improve the reliability and service life of the magnetic pump for continuous operation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6 This invention provides a magnetic pump with a circulating cooling function, including a pump body 1, an isolation sleeve 4 fixedly connected to one side of the pump body 1, a protective shell 5 fixedly connected to one side of the pump body 1, a dual-end motor 6 fixedly connected to one side of the protective shell 5, a plurality of heat dissipation fins 7 fixedly connected to the outer surface of the dual-end motor 6, an interlayer 8 opened in the inner wall of the isolation sleeve 4, and annular cooling channels 9 opened in the inner walls of both the protective shell 5 and the heat dissipation fins 7, a magnetic rotor 10 fixedly connected to the output end of the dual-end motor 6, a toggle cam 11 fixedly connected to the outer surface of the magnetic rotor 10, a plurality of gears 12 rotatably connected to the inner wall of the protective shell 5, a vortex fan blade 13 fixedly connected to the inner wall of the gears 12, a collaborative cooling mechanism 2 provided on the outer wall of the dual-end motor 6, and a heat exchange enhancement mechanism 3 installed on the inner wall of the dual-end motor 6; Specifically, the isolation sleeve 4 mounted on one side of the pump body 1 isolates the conveying medium from the magnetic transmission structure, preventing medium leakage. The protective shell 5 is fixed on the outside of the pump body 1, protecting the internal transmission and cooling structures. The double-ended motor 6 installed at the end of the protective shell 5 provides power for the equipment operation. Multiple heat dissipation fins 7 on the outer wall of the double-ended motor 6 increase the heat dissipation area and achieve basic heat dissipation. The interlayer 8 inside the isolation sleeve 4, together with the annular cooling channel 9 on the inner wall of the protective shell 5 and the heat dissipation fins 7, forms a through-type liquid cooling circulation channel, which can continuously cool the core heat-generating components. The dual-end motor 6 can drive the magnetic rotor 10 and the outer toggle cam 11 to rotate synchronously. The toggle cam 11 can intermittently mesh with multiple gears 12 on the inner wall of the protective shell 5 and drive the gears 12 to rotate synchronously to drive the vortex fan blades 13 on both sides in opposite directions to form a unidirectional transport of refrigerant. At the same time, the cooperative cooling mechanism 2 on the outer wall of the dual-end motor 6 can coordinate with the air-cooled and liquid-cooled structures, and the enhanced heat exchange mechanism 3 on the inner wall further improves the internal heat exchange efficiency. The multiple cooling structures work together to effectively reduce the operating temperature of the equipment and ensure the stable and long-term operation of the magnetic pump.

[0032] Please see the appendix Figure 7 Appendix Figure 8 and attached Figure 9The collaborative cooling mechanism 2 includes a transmission rod 201. The inner wall of the transmission rod 201 is fixedly connected to the other output end of the double-ended motor 6. A cooling fan 202 is fixedly connected to the outer surface of the transmission rod 201. A dustproof heat dissipation shell 203 is fixedly connected to one side of the double-ended motor 6. A rotating shaft 204 is rotatably connected to both the dustproof heat dissipation shell 203 and the inner wall of the double-ended motor 6. A torsion spring 205 is fixedly connected to the outer surface of the rotating shaft 204. A rocking blade 206 is fixedly connected to the outer surface of the rotating shaft 204. A lever 207 is fixedly connected to the outer surface of the transmission rod 201. A limit post 208 is fixedly connected to the inner wall of the dustproof heat dissipation shell 203. Specifically, the collaborative cooling mechanism 2 is powered by the end of the double-ended motor 6. The transmission rod 201 is fixed to the output end of the other end of the double-ended motor 6 and can rotate synchronously with the motor. The transmission rod 201 drives the cooling fan 202 to rotate, providing continuous forced air cooling to the rear end of the double-ended motor 6. The dustproof heat dissipation shell 203 can prevent external dust and impurities from entering the equipment and protect the normal operation of the cooling structure. When the transmission rod 201 rotates, it drives the lever 207 to rotate and intermittently moves the swing blade 206, causing the rotating shaft 204 to rotate and torsion spring 205 to twist. After the lever 207 disengages, the torsion spring 205 rebounds and drives the swing blade 206 to quickly reset. The limiting post 208 can limit the swing amplitude of the blade. The reciprocating swing of the blade can disturb the airflow direction, causing the airflow to blow back and forth towards the heat dissipation fins 7. While the heat dissipation fins 7 dissipate heat for the double-ended motor 6, they also further cool the refrigerant in the annular cooling channel 9, enhancing the overall heat dissipation efficiency of the motor and achieving an auxiliary collaborative cooling effect.

[0033] Please see the appendix Figure 8 Appendix Figure 9 and attached Figure 10 The enhanced heat exchange mechanism 3 includes a support column 301, with both ends of the support column 301 fixedly connected to the inner wall of the double-end motor 6. A turbulence cone 302 is fixedly connected to the outer surface of the support column 301, and multiple flow dividers 303 are fixedly connected to the outer surface of the support column 301. A pressure booster wheel 304 is fixedly connected to the outer surface of the transmission rod 201. A guide groove 305 is opened on the inner wall of the pressure booster wheel 304. A guide plate 306 is fixedly connected to the inner wall of the double-end motor 6. Specifically, the enhanced heat exchange mechanism 3 is used to enhance the heat exchange and heat dissipation effect inside the double-ended motor 6. The support column 301 is fixed at both ends to the inner wall of the double-ended motor 6, which plays a role in stable support. At the same time, the turbulence cone 302 and multiple diverting blocks 303 on the outside of the support column 301 can disperse the stable water flow inside, disrupt the laminar flow state, and increase the contact surface of the refrigerant to improve the heat exchange efficiency. The transmission rod 201 drives the pressure wheel 304 to rotate synchronously. With the guide groove 305 inside the pressure wheel 304 and the guide plate 306 on the inner wall of the motor, the refrigerant can be guided and pressurized to accelerate the flow speed of the water inside the motor, improve the heat accumulation problem inside the motor, and perform circulating heat dissipation, which greatly improves the overall heat dissipation and heat exchange performance.

[0034] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The inner wall of the annular cooling channel 9 is connected to the inner wall of the interlayer 8. The outer wall of the actuating cam 11 meshes with the outer wall of the gear 12. The bottom of the double-ended motor 6 is fixedly connected to the engagement seat 14. The bottom of the pump body 1 is fixedly connected to the mounting seat 15. Multiple first sealing rings 16 are fixedly connected to both sides of the gear 12. The outer wall of the first sealing ring 16 is slidably connected to the inner wall of the protective shell 5. The outer surface of the transmission rod 201 is fixedly connected to the second sealing ring 17. The outer surface of the second sealing ring 17 is fixedly connected to the inner wall of the double-ended motor 6. Specifically, the inner wall of the annular cooling channel 9 is interconnected with the inner wall of the jacket 8, forming a through-flow cooling channel to ensure smooth flow of the cooling medium and achieve all-round cooling of the isolation sleeve 4, protective shell 5, and other core components. The outer wall of the cam 11 meshes with the outer wall of the gear 12, and the rotational power of the magnetic rotor 10 drives the gear 12 and the vortex fan blade 13 to operate, realizing mechanical air cooling linkage. The coupling seat 14 at the bottom of the double-end motor 6 cooperates with the mounting seat 15 at the bottom of the pump body 1 to achieve stable installation and fixation of the equipment as a whole. The first sealing ring 16 on both sides of the gear 12 slides and seals with the inner wall of the protective shell 5, and the second sealing ring 17 on the outer side of the transmission rod 201 seals the motor connection gap, effectively blocking impurities and improving the overall sealing and operational stability of the equipment.

[0035] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 10 One end of the torsion spring 205 is fixedly connected to the inner wall of the double-ended motor 6, the outer surface of the limiting post 208 is slidably connected to one side of the swing blade 206, the inner wall of the pump body 1 is rotatably connected to the impeller inner magnet 18, one end of the impeller inner magnet 18 is fixedly connected to the drive impeller 19, the top of the protective shell 5 and the double-ended motor 6 are both fixedly connected to the hanging lugs 20, and the inner wall of the pump body 1 is connected to the conveying pipe 21. Specifically, one end of the torsion spring 205 is fixed to the inner wall of the double-ended motor 6, which can provide elastic driving force for the reset of the swaying blade 206. The limiting post 208 slides with the swaying blade 206, which can limit the swaying stroke of the blade and avoid structural collision interference. The impeller inner magnet 18 is rotatably installed inside the pump body 1. The end of the impeller inner magnet 18 is connected to the drive impeller 19. The drive impeller 19 is driven to rotate by magnetic coupling, which works with the conveying pipeline 21 to complete the medium conveying operation. The lugs 20 set on the top of the protective shell 5 and the double-ended motor 6 facilitate the hoisting, handling and installation of the equipment, and improve the ease of assembly.

[0036] Working principle: During operation, the pump body 1 is separated from the conveying medium by the isolation sleeve 4 on one side, which effectively prevents the medium from leaking. The outer protective shell 5 protects the internal transmission and cooling components. The double-ended motor 6 serves as the power source to drive the equipment. The heat dissipation fins 7 on its outer wall expand the heat dissipation area to achieve basic heat dissipation. The interlayer 8 inside the isolation sleeve 4 is connected to the annular cooling channel 9 on the inner wall of the protective shell 5 and the heat dissipation fins 7 to form a through-type liquid cooling channel. The double-ended motor 6 drives the magnetic rotor 10 and the actuating cam 11 to rotate synchronously. The actuating cam 11 intermittently meshes with the gear 12, which drives the vortex fan blades 13 on both sides to rotate in the opposite direction, pushing the cooling medium to be conveyed in one direction, thereby completing the continuous circulation cooling operation. During operation, the transmission rod 201 rotates synchronously with the motor, driving the cooling fan 202 to operate and providing forced air cooling to the rear end of the dual-end motor 6. The dustproof heat dissipation shell 203 can prevent external dust from entering and ensure the stable operation of the cooling components. During the rotation of the transmission rod 201, the lever 207 will intermittently move the swing blades 206, driving the rotating shaft 204 to rotate and torsion spring 205. When the lever 207 is disengaged, the torsion spring 205 elastically resets and drives the blades to swing back. The limit post 208 can limit its swing stroke. The reciprocating motion of the blades continuously disturbs the airflow and continuously blows on the heat dissipation fins 7, further cooling the cooling medium in the dual-end motor 6 and the annular cooling channel 9, effectively enhancing the overall heat dissipation effect and completing the auxiliary and collaborative cooling operation. When the enhanced heat exchange mechanism 3 is working, the support column 301 is fixed to the inner wall of the double-ended motor 6, which plays a role in providing stable support. At the same time, the turbulence cone 302 and the flow divider 303 on the outside of the support column 301 can break the laminar flow state of the cooling medium, expand the contact area between the medium and the components, and effectively improve the heat exchange efficiency. The transmission rod 201 drives the pressure wheel 304 to rotate synchronously. The guide groove 305 inside the pressure wheel 304, together with the guide plate 306 on the inner wall of the motor, guides and pressurizes the cooling medium, accelerates the medium circulation speed, avoids local heat accumulation, continuously optimizes the circulation heat dissipation effect, and significantly improves the overall heat exchange and heat dissipation capacity of the equipment.
