Description

Technical Field

[0001] This utility model relates to the technical field of magnetic pump auxiliary equipment, specifically a magnetic pump heat dissipation device. Background Technology

[0002] Magnetic drive pumps are widely used for transporting corrosive, flammable, and explosive media due to their seal-free and leak-proof characteristics. However, during operation, the motor, bearings, and magnetic coupling components generate a large amount of heat. If heat dissipation is not timely, overheating damage to these components can easily occur (such as motor burnout or bearing seizure). Existing magnetic drive pump cooling devices suffer from the following key technical defects, making it difficult to meet the requirements for efficient heat dissipation: Limited heat dissipation range and severe heat accumulation: Traditional devices rely solely on a single ventilation hole at the bottom for heat dissipation. Heat from the upper and side parts of the magnetic pump (such as the motor housing and magnetic cylinder) cannot be effectively dissipated, forming localized high-temperature zones and shortening the lifespan of critical components. Uncontrollable air output leads to a conflict between energy consumption and heat dissipation: The opening of the heat dissipation channel is fixed, making it impossible to adjust the air output according to the magnetic pump load. Under low loads, there is excessive airflow, wasting electricity; under high loads, there is insufficient airflow, resulting in poor heat dissipation and an inability to adapt to different operating conditions. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic pump cooling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetic pump cooling device, comprising a support base and a bent tube. Two sets of air inlet pipes are fixedly connected to the lower part of the support base. Several sets of first connecting holes are opened in the middle of the upper side of the support base. Several sets of vent pipes are fixedly connected inside the upper two sides of the support base. Four sets of first vent holes are opened around the vent pipes. A plug is slidably connected inside the vent pipe. A connecting piece is fixedly connected to the lower part of the plug. A first spring is fixedly connected between the connecting piece and the inner wall of the support base. The first spring is sleeved on the outside of the vent pipe. Both ends of the bent tube are slidably connected inside the vent pipe. Second vent holes are opened around both ends of the bent tube. Several sets of air outlets are opened inside the bent tube.

[0005] Preferably, a mounting bracket is fixedly connected inside the air intake pipe, a motor is fixedly connected to one side of the mounting bracket, and a fan is fixedly connected to the power end of the motor.

[0006] Preferably, a first isolation net is fixedly connected to the inside of both ends of the air intake pipe, and a second isolation net is fixedly connected to the inner side of the upper part of the support base.

[0007] Preferably, a fixing plate is fixedly connected to both sides of the upper part of the support base, and a locking rod facing the vent pipe is slidably connected inside the fixing plate. A connecting frame is fixedly connected to both sides of the lower part of the curved pipe, and a locking hole for cooperating with the locking rod is opened on the inner side of the connecting frame.

[0008] Preferably, a connecting plate is fixedly connected to one end of the locking rod, and a second spring is fixedly connected between the two sides of the connecting plate and the fixing plate, with the second spring sleeved on the outer side of the two locking rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model blows air to the bottom of the magnetic pump through the first connecting hole at the bottom, and blows air to the top and sides around the outlet of the curved tube at the top, forming a "three-dimensional surround" heat dissipation. This avoids the heat accumulation at the top caused by traditional single bottom heat dissipation, and provides all-round heat dissipation without local accumulation. The temperature of key components of the magnetic pump is well cooled, and the service life is extended. 2. This utility model also adjusts the position of the baffle by rotating the threaded rod, thereby changing the overlapping area of ​​the second connecting hole and the first connecting hole. This allows for flexible control of the lower air output. Under high load, the air output is increased to enhance heat dissipation, while under low load, the air output is reduced to save energy. It can adapt to different operating conditions without replacing the heat dissipation components. The air output is precise and controllable, making it suitable for multiple working conditions. 3. This utility model also allows for ventilation by inserting a bent tube into the vent pipe and pushing the plug. The locking rod automatically inserts into the locking hole under the action of the spring to complete the fixation. Disassembly can be performed by simply pulling the connecting plate without tools. The disassembly and assembly time is short. The bent tube can be removed when heat dissipation is not required, without affecting other operations of the magnetic pump, and it is highly flexible.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a magnetic pump cooling device, including a support base 1 and a bent pipe 24. Two sets of air inlet pipes 9 are fixedly connected to the lower sides of the support base 1 by welding, serving as air intake channels for cooling air. Several sets of first connecting holes 7 are evenly opened in the middle of the upper side of the support base 1, allowing the intake air to be blown towards the lower part of the magnetic pump through the first connecting holes 7, thus achieving cooling of the lower part. Several sets of vent pipes 2 are fixedly connected to the upper sides of the support base 1 by welding, used to guide the airflow upward. Four sets of first vent holes 3 are evenly opened along the circumference of the vent pipe 2. A plug 4 is slidably connected inside the vent pipe 2 by clearance fit, used to seal the first vent holes 3. A connecting piece 5 is fixedly connected to the lower part of the plug 4 by welding. A first spring 6 is fixedly connected to the inner wall of the support base 1 by spot welding between the connecting piece 5 and the support base 1. The first spring 6 is sleeved on the outside of the vent pipe 2. Under normal conditions, it pushes the plug 4 to move upward and seals the first vent hole 3. The two ends of the bent tube 24 are slidably connected to the inside of the vent pipe 2 by clearance fit. The two ends of the bent tube 24 are provided with second vent holes 26 on the periphery. Several sets of air outlets 25 are evenly provided on the inner side of the bent tube 24 facing the magnetic pump. When the bent tube 24 is inserted into the vent pipe 2, it pushes the plug 4 to slide downward, the first spring 6 is stretched, the second vent hole 26 is aligned and connected with the first vent hole 3, and the airflow can enter the bent tube 24 from the vent pipe 2 through the vent hole, and then blow from the air outlet 25 to the upper and side of the magnetic pump to achieve circumferential heat dissipation. Inside the air intake pipe 9, a mounting bracket 10 is fixedly connected by welding. A motor 11 is fixedly connected to one side of the mounting bracket 10 by flange bolts. A fan 12 is fixedly connected to the power end of the motor 11 by a key. Starting the motor 11 can drive the fan 12 to rotate, generating negative pressure to draw in outside air. The first isolation net 8 is fixedly connected to both ends of the air intake pipe 9 by bolts. It is used to filter dust, fibers and other debris in the intake air and prevent blockage of the air intake pipe 9. The second isolation net 13 is fixedly connected to the inner side of the upper part of the support base 1 by bolts, covering the area below the first connecting hole 7 and preventing debris generated during the operation of the magnetic pump from falling into the interior of the support base 1. The upper two sides of the support base 1 are fixedly connected to the fixing plate 20 by bolts. The fixing plate 20 is slidably connected to the locking rod 21 through clearance fit. The lower two sides of the bent tube 24 are fixedly connected to the connecting frame 27 by welding. The connecting frame 27 has a locking hole 28 that matches the locking rod 21 on the inner side. One end of the locking rod 21 is fixedly connected to the connecting plate 22 by welding. The two sides of the connecting plate 22 are fixedly connected to the fixing plate 20 by spot welding. The second spring 23 is sleeved on the outside of the locking rod 21. Under normal conditions, it pushes the locking rod 21 to move towards the bent tube 24. When the bent tube 24 is installed in place, the locking rod 21 automatically inserts into the locking hole 28 to realize the quick fixation of the bent tube 24 and prevent displacement during operation. A control groove 14 is provided on the inner side of the upper part of the support base 1. A guide rod 17 is fixedly connected to the inside of the control groove 14 by welding. A baffle 15 is slidably connected to the outside of the guide rod 17 by clearance fit. A second connecting hole 16 is provided in the middle of the baffle 15 to cooperate with the first connecting hole 7. A threaded rod 18 is threadedly connected to the inside of the other side of the baffle 15. The two ends of the threaded rod 18 are rotatably connected to the inner wall of the control groove 14 by deep groove ball bearings. Rotating the threaded rod 18 can drive the baffle 15 to slide along the guide rod 17, changing the overlapping area of ​​the second connecting hole 16 and the first connecting hole 7, thereby controlling the air output of the lower heat dissipation. The larger the overlapping area, the larger the air output and the stronger the heat dissipation. Four sets of support legs 19 are fixedly connected to the four corners of the lower part of the support base 1 by welding, which are used to raise the support base 1 to facilitate bottom air intake.

[0016] Working principle: When using this utility model: place the magnetic pump to be cooled stably on the upper surface of the support base 1, ensuring that the heat dissipation area at the bottom of the magnetic pump is directly opposite the first connecting hole 7, and avoid blocking the lower air intake channel; confirm that the first isolation net 8 and the second isolation net 13 are not damaged or blocked, and clean any debris first; Depending on the operating load of the magnetic pump, rotate the threaded rod 18. The threaded rod 18 rotates relative to the control groove 14 through the deep groove ball bearing, causing the baffle 15 to slide horizontally along the guide rod 17. Observe the overlapping area of ​​the second connecting hole 16 and the first connecting hole 7. If the load is high, the air output needs to be increased so that the second connecting hole 16 and the first connecting hole 7 completely overlap. If the load is low, the air output needs to be reduced so that the second connecting hole 16 only partially overlaps. After the adjustment is completed, stop rotating the threaded rod 18, and the position of the baffle 15 is fixed. Holding the bent tube 24, align its two ends with the vent pipes 2 on both sides of the support base 1, and slowly insert it into the vent pipe 2; during the insertion process, the end of the bent tube 24 pushes the plug 4 to slide downward, and the first spring 6 is stretched; continue to insert until the second vent hole 26 of the bent tube 24 is completely aligned with the first vent hole 3 of the vent pipe 2, at which point the locking hole 28 of the connecting bracket 27 is aligned with the locking rod 21; under the pushing force of the second spring 23, the locking rod 21 automatically inserts into the locking hole 28, completing the fixation of the bent tube 24 and preventing it from shifting due to vibration during operation; When the power supply to the motor 11 is turned on, the motor 11 drives the fan 12 to rotate at high speed, generating negative pressure to draw in external air from the air intake pipe 9: part of the air is blown towards the lower part of the magnetic pump through the first connecting hole 7 and the second connecting hole 16, taking away the heat at the bottom; the other part of the air enters the ventilation pipe 2, enters the bent pipe 24 through the first ventilation hole 3 and the second ventilation hole 26, and then is blown evenly towards the upper and side parts of the magnetic pump from the air outlet 25, achieving all-round surrounding heat dissipation; If no further heat dissipation is needed or the magnetic pump needs to be moved, pull the connecting plate 22. The connecting plate 22 will cause the locking rod 21 to slide outward, the second spring 23 will be compressed, and the locking rod 21 will disengage from the locking hole 28. At this time, the plug 4 will reset upward under the action of the first spring 6, and re-seal the first vent hole 3 to prevent debris from entering the vent pipe 2.
