Description

Technical Field

[0001] This utility model relates to the field of magnetic pump technology, specifically a high-temperature resistant magnetic pump. Background Technology

[0002] A magnetic drive pump mainly consists of several parts, including a pump head, a magnetic drive unit, a motor, and a base. The magnetic drive unit comprises an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate via a coupling, the magnetic field can penetrate the air gap and the non-magnetic isolation sleeve, driving the inner magnetic rotor, which is connected to the impeller, to rotate synchronously. This achieves contactless synchronous power transmission, transforming the easily leaking dynamic sealing structure into a zero-leakage static sealing structure.

[0003] The zero-leakage characteristic of magnetic pumps makes them suitable for transporting flammable, explosive, and high-pressure media in chemical plants. However, due to their harsh working environment, a large amount of dust will accumulate on the surface of the pump body during operation. Dust accumulation affects the heat dissipation of the pump body, which can easily cause the internal temperature to become too high, leading to pump overload and damage, and thus affecting the service life of the magnetic pump. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant magnetic pump, which solves the problem that a large amount of dust accumulates on the pump body surface during operation. This dust accumulation affects the heat dissipation of the pump body, easily causing excessive internal temperature, leading to pump overload and damage, and thus affecting the service life of the magnetic pump.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-temperature resistant magnetic pump, including a pump body, an mounting plate fixedly connected to the bottom of the pump body, cooling rings fixedly connected to both sides of the top of the mounting plate, through holes opened in the inner walls of the two cooling rings, the inner walls of the through holes being sleeved on the outer walls of the pump body, and an automatic cooling component installed on the outer walls of the cooling rings.

[0006] Preferably, the automatic cooling component includes a temperature sensor, which is fixedly connected to the outer wall of the pump body. The temperature sensor is electrically connected to a PLC controller, the bottom of which is fixedly connected to the top of the mounting plate. The PLC controller is electrically connected to a circulating pump, the bottom of which is fixedly connected to the top of the mounting plate. The output end of the circulating pump is connected to a cooling ring. A heat sink is installed on the outer wall of the cooling ring, and a return flow component is installed on the outer wall of the cooling ring.

[0007] Preferably, the reflux assembly includes a connecting pipe, the two ends of which are respectively connected to cooling rings on both sides. The outer wall of the cooling ring is connected to a liquid tank. The bottom of the liquid tank is fixedly connected to the top of the mounting plate. The outer wall of the liquid tank is connected to a reflux pipe, and the end of the reflux pipe is connected to the input end of the circulation pump.

[0008] Preferably, a mounting frame is provided on one side of the outer wall of the pump body, a fan is fixedly connected to the inner wall of the mounting frame, the fan is electrically connected to the PLC controller, and a ventilation pipe is connected to the outer wall of the mounting frame.

[0009] Preferably, an installation strip is fixedly connected to the top of the mounting frame, a support rod is fixedly connected to the bottom of the installation strip, and the bottom of the support rod is fixedly connected to the top of the mounting plate. Beneficial effects

[0010] This invention provides a high-temperature resistant magnetic pump. It offers the following advantages: Through the cooperation of a cooling ring, pump body, and automatic cooling components, when the pump body temperature becomes too high, the automatic cooling components control the cooling ring to cool the pump body, preventing damage due to overheating. This also solves the problem of dust accumulation on the pump body surface during operation, which hinders heat dissipation, easily leading to excessive internal temperature, pump overload, and damage, thus affecting the service life of the magnetic pump.

[0011] By using the mounting frame, fan, and ventilation duct in conjunction with each other, when the cooling effect of the cooling ring on the pump body decreases, the fan will start to cool the pump body and the cooling ring as a whole, thereby ensuring the temperature stability of the pump body. At the same time, the fan will also remove dust from the pump body, avoiding dust accumulation and solving the problem of existing pump bodies being damaged due to excessive temperature.

[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] During operation, a large amount of dust will accumulate on the surface of the pump body. Dust accumulation affects the heat dissipation of the pump body, which can easily cause the internal temperature to be too high, leading to pump overload and damage, and thus affecting the service life of the magnetic pump.

[0016] In view of this, the present invention provides a high-temperature resistant magnetic pump, which solves the problem that a large amount of dust will fall on the surface of the pump body during operation. The accumulation of dust affects the heat dissipation of the pump body, which can easily cause the internal temperature to be too high, leading to pump body overload and damage, and thus affecting the service life of the magnetic pump.

[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0018] Example 1: By Figure 1-4 It is known that a high-temperature resistant magnetic pump includes a pump body 1, a mounting plate 2 is fixedly connected to the bottom of the pump body 1, and cooling rings 5 ​​are fixedly connected to both sides of the top of the mounting plate 2. The inner walls of the two cooling rings 5 ​​are provided with through holes 12, and the inner walls of the through holes 12 are fitted onto the outer walls of the pump body 1. An automatic cooling component is installed on the outer walls of the cooling rings 5. In the specific implementation process, it is worth noting that a cavity is set inside the cooling ring 5 to allow liquid to flow inside. The liquid inside the cooling ring 5 is an ethylene glycol solution, which can effectively absorb and conduct heat, thus better absorbing the temperature of the pump body 1. The through hole 12 on the inner wall of the cooling ring 5 is used to install the cooling ring 5 on the outer wall of the pump body 1. The mounting plate 2 is used to support and fix the entire device. When the temperature of the pump body 1 rises during operation, the automatic cooling component will control the cooling ring 5 to cool the pump body 1, ensuring that the pump body 1 is not damaged due to excessively high operating temperature over a long period of time. The pump body 1 is a magnetic pump, and the specific model can be determined according to the actual use. Furthermore, the automatic cooling component includes a temperature sensor 3, which is fixedly connected to the outer wall of the pump body 1. The temperature sensor 3 is electrically connected to a PLC controller 4, the bottom of which is fixedly connected to the top of the mounting plate 2. The PLC controller 4 is electrically connected to a circulating pump 10, the bottom of which is fixedly connected to the top of the mounting plate 2. The output end of the circulating pump 10 is connected to a cooling ring 5. A heat sink 16 is installed on the outer wall of the cooling ring 5, and a return flow component is installed on the outer wall of the cooling ring 5. In the specific implementation process, it is worth noting that the temperature sensor 3 can detect the temperature of the pump body 1, and the operator can use the PLC controller 4 to set the trigger temperature of the temperature sensor 3. When the temperature of the pump body 1 triggers the temperature sensor 3, the temperature sensor 3 will transmit the signal to the PLC controller 4. After processing the signal, the PLC controller 4 will control the circulating pump 10 to work, so that the liquid in the cooling ring 5 will circulate, thereby absorbing and carrying away the heat of the pump body 1. This can continuously cool the pump body 1. In addition, the heat sink 16 on the outer wall of the cooling ring 5 is made of copper, which can quickly conduct the temperature of the liquid outward, so that the liquid in the cooling ring 5 can continuously dissipate heat from the pump body 1. The models of the above electronic components are not limited, as long as they meet the actual use conditions, and they can be connected to the same power supply as the pump body 1. If necessary, necessary electronic components can be added for adaptation, such as transformers, air switches, etc. Furthermore, the reflux assembly includes a connecting pipe 6, with both ends of the connecting pipe 6 connected to the cooling rings 5 ​​on both sides respectively. The outer wall of the cooling rings 5 ​​is connected to a liquid tank 9. The bottom of the liquid tank 9 is fixedly connected to the top of the mounting plate 2. The outer wall of the liquid tank 9 is connected to a reflux pipe 11, and the end of the reflux pipe 11 is connected to the input end of the circulating pump 10. In the specific implementation process, it is worth noting that the two cooling rings 5 ​​are connected by the connecting pipe 6, which ensures that the liquid flows inside both rings. The top cover of the liquid tank 9 can be opened to add or replace the liquid. With the cooperation of the return pipe 11, the liquid in the liquid tank 9 enters the circulation pump 10 for continuous use.

[0019] Example 2: From Figure 1-4 It can be seen that a mounting frame 14 is provided on one side of the outer wall of the pump body 1, a fan 15 is fixedly connected to the inner wall of the mounting frame 14, the fan 15 is electrically connected to the PLC controller 4, and a ventilation pipe 8 is connected to the outer wall of the mounting frame 14. In the specific implementation process, it is worth noting that the mounting frame 14 is used to support the fan 15, and the ventilation pipe 8 can stabilize the gas flow. When the temperature of the pump body 1 continues to rise, the PLC controller 4 will control the fan 15 to work, so that the gas blows towards the cooling ring 5 and the heat sink 16, accelerating the rapid dissipation of heat from both, thereby further improving the cooling effect on the pump body 1. The model of the fan 15 is not limited, as long as it meets the actual use conditions. Furthermore, the top of the mounting frame 14 is fixedly connected to the mounting strip 7, the bottom of the mounting strip 7 is fixedly connected to the support rod 13, and the bottom of the support rod 13 is fixedly connected to the top of the mounting plate 2. In the specific implementation process, it is worth noting that the mounting strip 7 is used to support the fan 15 and the mounting frame 14, and the support rod 13 is used to fix and support the mounting strip 7 to ensure that the fan 15 is stable when it is working.
