Description

Technical Field

[0001] The present invention belongs to the technical field of magnetic pump structures, and specifically relates to a magnetic pump structure with noise reduction and easy cooling. Background Art

[0002] When a magnetic pump is cooled, a water circulation cooling method is mostly adopted. The water circulation mostly uses a pumping method. The pump for pumping the conveying water flow is prone to generate excessive power consumption during operation. And when the pumping pump is damaged, it is easy to delay the normal operation of the magnetic pump. The water circulation cooling mostly uses a pipeline winding method for cooling. When the pipeline coverage area is large, it is easy to affect the cooling effect of the rear section of the pipeline; when a magnetic pump using water circulation cooling is cooled, the heat generated by the internal structure of the magnetic pump during operation varies in size, and the transmission conduit is...

[0003] A magnetic pump structure with a self-cooling function disclosed in Chinese invention patent CN118030546A, under the adjustment of an adjusting sleeve on an adjusting push rod, the adjusting sleeve is sleeved outside the connecting shaft when needed, so that when the magnetic pump rotates, it drives the connecting shaft to rotate. When the adjusting sleeve rotates, it can drive a rotating gear disk to rotate, so that the rotating gear disk drives a telescopic hose to extract the cooling liquid inside the cold water tank for temperature reduction operation, and the transmission conduit can be divided into multiple sections by the whole section and supplied through multiple telescopic hoses, so that the cooling effect on the front and rear sections inside the magnetic pump is improved, and the rotation of the rotating gear disk is driven by the rotation of the magnetic pump itself, without consuming too much electric power resources. And when the magnetic pump stops working, the cooling operation of the transmission conduit stops synchronously, and the normal operation of the magnetic pump will not be affected by the damage of other equipment.

[0004] In the prior art, for the temperature reduction of magnetic pumps, most still adopt heat absorption and temperature reduction outside the pump body. However, the structure of the magnetic pump is special, and the heat generation concentration point is near the rotor. And because the magnetic pump has multiple magnetic sleeves and isolation sleeves, it is very difficult for the heat inside the rotor to be transferred outward. Simply absorbing heat outside the pump body is very difficult to achieve the expected cooling effect. Summary of the Invention

The input pipe penetrates through the front end of the liquid tank and extends inside, and the output pipe penetrates through the rear end of the liquid tank and extends inside.

[0009] An isolation plate is centrally arranged inside the liquid tank. A through hole is opened at the bottom of the isolation plate and the inner bottom surface of the liquid tank. The liquid tank is divided into two cavities by the isolation plate. A water pump is arranged in the front cavity of the liquid tank. The output end of the water pump is connected to the end of the input pipe. A rain shower pipe is arranged at the rear end of the liquid tank. The interface of the rain shower pipe is connected to the end of the output pipe.

[0010] A fitting box is penetrated and arranged at the rear end of the liquid tank. A drawer is arranged inside the fitting box. A semiconductor refrigeration sheet is arranged on the drawer. A plurality of heat dissipation fins are arranged on the upper surface of the fitting box. The fitting box is located below the rain shower pipe.

[0011] The front end of the isolation sleeve protrudes from the front end of the outer magnetic sleeve. A cushion sleeve is fixedly sleeved on the front end of the isolation sleeve. A protective sleeve is sleeved outside the outer magnetic sleeve. One end of the protective sleeve is connected to the connection disk, and the other end of the protective sleeve is connected to the outer surface of the cushion sleeve.

[0012] A pipe joint is integrally arranged at the front end of the protective sleeve. The pump shaft penetrates through the front end of the pipe joint. An impeller is installed at the end of the pump shaft. A wheel sleeve is centrally arranged on the front surface of the pipe joint. The impeller is located inside the wheel sleeve. The pipe joint is provided with a water inlet and a water outlet.

[0013] A port sealing piece is integrally arranged at the front end of the protective sleeve. The port sealing piece is provided with a groove. A sealing ring is arranged inside the groove. One end of the pipe joint is embedded in the groove and is connected by bolts.

[0014] A sound insulation sleeve is sleeved outside the protective sleeve. One end of the sound insulation sleeve is attached to the outer surface of the port sealing piece. The other end of the sound insulation sleeve is provided with a plurality of connecting ears. The connecting ears are fixed to the front end of the motor by screws. A cavity is arranged between the sound insulation sleeve and the protective sleeve. Sound insulation materials are filled in the cavity. The input pipe and the output pipe both penetrate through the sound insulation sleeve.

[0015] The diameter of the inner magnetic sleeve is smaller than that of the isolation sleeve, and a sleeve is also provided on the inner magnetic sleeve. The diameter of the sleeve is larger than that of the shaft cylinder. The solenoid is placed between the sleeve and the shaft cylinder and does not contact either of them. A plurality of inner magnetic rotors are arranged on the outer surface of the sleeve at equal intervals in a circumferential manner.

[0016] A convex ring is centrally provided at one end of the isolation sleeve close to the drive shaft, and one end of the pump shaft is rotatably connected within the convex ring. A bearing sleeve is centrally provided at the front end of the isolation sleeve, and the pump shaft is fixedly connected to the inner ring of the bearing sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) In the present invention, the sound insulation sleeve is wrapped outside the protective sleeve, and a cavity is formed between the two and filled with sound insulation materials. This structure can effectively block the noise generated during the operation of the magnetic pump from spreading outward and reduce the noise pollution to the surrounding environment; one end of the sound insulation sleeve is attached to the outer surface of the port sealing piece, and the other end is fixed to the front end of the motor through the connecting ear. This tight connection method can minimize the sound leakage channels to improve the sound insulation effect.

[0019] (2) A solenoid is arranged inside the inner magnetic sleeve of the present invention. The solenoid is arranged around the sleeve and does not contact the sleeve, so as not to affect the rotation of the inner magnetic sleeve. The coolant is transported to the solenoid through the water pump and the input pipe in the liquid tank. The solenoid is located near the key heat - generating part of the magnetic pump, that is, near the rotor. This layout enables the coolant to quickly reach the source of heat generation and directly adsorb the heat generated during the movement of the rotor. Since the rotor is one of the main heat - generating components during the operation of the magnetic pump, through the relative position design of the solenoid and the rotor, efficient heat transfer can be achieved, and the heat can be taken away from the generation site in time to prevent heat accumulation from damaging the components.

[0020] (3) During the entire cooling cycle of the present invention, after the coolant absorbs heat from the solenoid, it then enters the rain pipe through the output pipe for spraying. This closed - loop system can effectively transfer the heat inside the magnetic pump to the external liquid tank environment. When the magnetic pump is running, heat is continuously generated. This circulation mechanism ensures that the heat can be continuously transferred, maintaining the temperature inside the magnetic pump within a suitable range, thereby ensuring the stable operation of the magnetic pump.

[0021] (4) Inside the liquid tank of the present invention, a rain shower pipe and an embedded box are provided. Inside the embedded box in the liquid tank, a semiconductor refrigeration chip is provided. When the coolant sprayed by the rain shower pipe contacts the embedded box, the semiconductor refrigeration chip comes into play. The semiconductor refrigeration chip can not only generate cold air, but also, due to the fact that the cold air is heavier and moves downward, this characteristic enables the cold air to come into full contact with the coolant in the liquid tank. The refrigeration effect of the semiconductor refrigeration chip provides additional assistance for the cooling of the coolant, further reducing the temperature of the coolant. Further, according to the existing semiconductor refrigeration chip technology, it can be adjusted according to the working state of the magnetic pump and the actual temperature requirement. When the magnetic pump is running at high load and generating a large amount of heat, the semiconductor refrigeration chip can increase the refrigeration power to ensure that the coolant can be quickly cooled down, thereby effectively controlling the temperature of the magnetic pump; while when running at low load, the refrigeration power can also be appropriately adjusted to avoid overcooling and achieve the purpose of energy conservation.

[0022] (5) In the present invention, the entire cooling mechanism forms a complete circulation system. Starting from the liquid tank, the coolant is transported to the spiral pipe inside the magnetic pump through the water pump, and then the coolant after absorbing heat is brought back to the rain shower pipe in the liquid tank for spray cooling. At the same time, the semiconductor refrigeration chip is used to further cool the coolant, and then the coolant can be transported to the spiral pipe again by the water pump for the next round of cooling cycle. This sustainable circulation system can continuously and stably provide cooling for the magnetic pump, ensuring that the magnetic pump will not malfunction due to overheating during long-term operation. At the same time, the various components in the cooling cycle work together. The water pump provides the power for the coolant circulation to ensure that the coolant can flow stably throughout the system; the spiral pipe effectively adsorbs heat and transfers it; the rain shower pipe realizes the spray heat dissipation of the coolant; the semiconductor refrigeration chip enhances the cooling effect of the coolant. The various components cooperate with each other, enabling the entire cooling mechanism to efficiently achieve the cooling function of the magnetic pump. Description of the Drawings

[0035] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the drawings of the specification.

[0036] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0038] Refer to Figures 1-3This is a structural diagram of a noise-reducing and easy-cooling magnetic pump in this embodiment. The magnetic pump in this embodiment includes a motor 100, and a drive shaft 101 is centrally assembled on the output end of the motor 100. Refer to Figure 4 , on the drive shaft 101 in this embodiment, an outer magnetic sleeve 103 is fixedly sleeved. A plurality of outer magnetic rotors 1031 are arranged on the inner surface of the outer magnetic sleeve 103 at equal intervals in a circumferential manner. And an isolation sleeve 104 is arranged inside the outer magnetic sleeve 103. The diameter of the isolation sleeve 104 is smaller than the inner diameter of the outer magnetic sleeve 103. An inner magnetic sleeve 105 is arranged inside the isolation sleeve 104. And a shaft cylinder is integrally connected to the center of the inner magnetic sleeve 105. A pump shaft 106 is fixedly inserted into the shaft cylinder. The pump shaft 106, the inner magnetic sleeve 105, the isolation sleeve 104, and the outer magnetic sleeve 103 are all concentric. The concentric structure can reduce the friction and wear between components, improve the working efficiency and service life of the magnetic pump. This embodiment discloses the existing structure and its components of the magnetic pump, so as to facilitate a detailed description of the installation position of the noise-reducing and easy-cooling structure inside the magnetic pump.

[0039] Refer to Figures 4-6 This is a structural diagram of the noise-reducing and easy-cooling of the magnetic pump in this embodiment. The noise-reducing and easy-cooling structure of the magnetic pump in this embodiment includes a spiral tube 200 arranged inside the inner magnetic sleeve 105. The spiral tube 200 is arranged around the sleeve, and the spiral tube 200 does not contact the sleeve. One end of the spiral tube 200 is connected to a pipe to form an input pipe 201, and the other end of the spiral tube 200 is connected to a pipe to form an output pipe 202. Both the input pipe 201 and the output pipe 202 penetrate through the isolation sleeve 104 and extend out of the outer magnetic sleeve 103 from the gap between the isolation sleeve 104 and the outer magnetic sleeve 103. In this embodiment, the spiral tube 200, the input pipe 201, and the output pipe 202 do not contact the rotatable inner magnetic sleeve 105 and outer magnetic sleeve 103 in the magnetic pump, so that the magnetic pump will not be affected by the spiral tube 200, the input pipe 201, and the output pipe 202 during operation. In this embodiment, a coolant is used to adsorb the heat generated when the magnetic pump works. The coolant enters the spiral tube 200 through the input pipe 201. The spiral tube 200 is located in the rotor of the magnetic pump, which is the main area where heat is generated at this position. When the coolant absorbs heat, it is discharged through the output pipe 202.

[0040] Refer to Figure 2In this embodiment, a connecting plate 102 is integrally connected to the output end of the motor 100, and the connecting plate 102 is connected to a connecting plate 2031 by bolts. A liquid tank 203 is arranged on the connecting plate 2031. In this embodiment, the cooling liquid for absorbing heat is stored in the liquid tank 203, and the input pipe 201 extends through the front end of the liquid tank 203 to the inside, and the output pipe 202 extends through the rear end of the liquid tank 203 to the inside. In this embodiment, since the input pipe 201 is used to input the cooled cooling liquid into the spiral tube 200, and the output pipe 202 is used to re-inject the cooling liquid after absorbing heat in the spiral tube 20 into the liquid tank 203, in order to prevent the cooling liquid after absorbing heat from mixing quickly with the cooling liquid after cooling, the liquid tank 203 is provided with a plurality of cooling elements in the liquid tank 203. An isolation plate is provided in the middle to slow down the rapid mixing of cold and hot coolants, providing a buffer time for the coolant to cool down again after absorbing heat. A through hole is opened at the bottom of the isolation plate and the inner bottom surface of the liquid tank 203 for liquid flow to form a circulation. The liquid tank 203 is divided into two cavities by the isolation plate. A water pump 2011 is built into the front cavity of the liquid tank 203, and the output end of the water pump 2011 is connected to the end of the input pipe 201. A shower pipe 2021 is provided at the rear end of the liquid tank 203, and the interface of the shower pipe 2021 is connected to the end of the output pipe 202. The coolant after absorbing heat is sprayed through the shower pipe 2021, so that the heat is first released during the spraying process, and the cooled coolant is re-injected into the spiral tube 200 through the water pump 2011 as a power.

[0041] See also Figure 8 and Figure 9 Simply spraying and cooling the coolant after absorbing heat through the shower pipe 2021 is strange, and the heat dissipation efficiency is far from achieving the purpose of recycling. Therefore, in order to ensure that the coolant after absorbing heat can be quickly cooled down and restored to a temperature that can be reused, this embodiment is provided with an embedded box 204 at the rear end of the liquid tank 203, and the embedded box 204 has a built-in drawer 2041. The drawer 2041 is provided with a semiconductor refrigeration plate, and the upper surface of the embedded box 204 is provided with a plurality of heat dissipation fins, and the embedded box 204 is located below the shower pipe 2021. In this embodiment, due to the semiconductor refrigeration plate in the embedded box 204, the surface temperature is relatively low. When the coolant sprayed through the shower pipe 2021 contacts the embedded box 204 again, the heat therein is quickly released, thereby reducing it to a usable temperature.

[0042] Based on the above technical solution, in this embodiment, starting from the liquid tank 203, the coolant is transported to the spiral tube 200 inside the magnetic pump through the water pump 2011, and then the heated coolant is brought back to the rain pipe 2021 in the liquid tank 203 for spray cooling. At the same time, the coolant is further cooled by the semiconductor refrigeration sheet, and then the coolant can be transported to the spiral tube 200 by the water pump 2011 again for the next round of cooling cycle. The spiral tube 200 is located in the inner magnetic sleeve 105 of the magnetic pump, and this part is the key heat-generating part, enabling the coolant to quickly reach the source of heat generation and directly adsorb the heat generated during the rotor movement. Since the rotor is one of the main heat-generating components during the operation of the magnetic pump, through the design of the relative position between the spiral tube 200 and the rotor, efficient heat transfer can be achieved, and the heat can be taken away from the generation site in a timely manner to prevent heat accumulation from damaging the components. During the entire cooling cycle, after the coolant absorbs heat from the spiral tube 200, it enters the rain pipe 2021 through the output pipe 202 for spraying. This closed-loop system can effectively transfer the heat inside the magnetic pump to the external liquid tank environment. When the magnetic pump is running, heat is continuously generated, and the technical solution of this embodiment ensures that the heat can be continuously transferred.

[0043] It should be noted that a sleeve is also provided on the inner magnetic sleeve 105 in this embodiment. The diameter of the sleeve is larger than that of the shaft cylinder. The spiral tube 200 is placed between the sleeve and the shaft cylinder and does not contact either of them. A plurality of inner magnetic rotors 1051 are arranged on the outer surface of the sleeve at equal intervals in a circumferential manner. When the motor 100 rotates in this embodiment, the outer magnetic sleeve 103 is directly driven to rotate through the drive shaft 101, and the outer magnetic rotor 1031 provided on the inner wall of the outer magnetic sleeve 103 will affect the inner magnetic rotor 1051 of the inner magnetic sleeve 105, so that the inner magnetic sleeve 105 rotates accordingly. This process is the operating principle of the magnetic pump rotation. Therefore, the diameter of the inner magnetic sleeve 105 in this embodiment is smaller than that of the isolation sleeve 104, thereby eliminating the friction with the isolation sleeve 104 and preventing the rotation of the inner magnetic sleeve 105 from being affected.

[0044] Refer to Figure 4 , in order to keep the isolation sleeve 104 stable, in this embodiment, the front end of the isolation sleeve 104 protrudes from the front end of the outer magnetic sleeve 103, and a cushion sleeve 1041 is fixedly sleeved on the front end of the isolation sleeve 104. A protective sleeve 107 is sleeved outside the outer magnetic sleeve 103. One end of the protective sleeve 107 is connected to the connection disk 102, and the other end of the protective sleeve 107 is connected to the outer surface of the cushion sleeve 1041. The stable connection structure in this embodiment helps to reduce the noise generated due to component vibration. When the magnetic pump is running, the relative stability between components can avoid additional noise generated due to loosening or collision.

[0045] Refer to Figure 5 and Figure 7, in this embodiment, a pipe joint 1071 is integrally provided at the front end of the protective sleeve 107, and the pump shaft 106 penetrates through the front end of the pipe joint 1071. An impeller 1061 is installed at the end of the pump shaft 106. A wheel sleeve 1062 is centrally provided on the front surface of the pipe joint 1071. The impeller 1061 is located within the wheel sleeve 1062. The pipe joint 1071 is provided with a water inlet and a water outlet. In this embodiment, the pump shaft 106 is fixedly sleeved with the inner magnetic sleeve 105. When the inner magnetic sleeve 105 rotates, it synchronously drives the pump shaft 106 to rotate. During the rotation of the impeller 1061 at the front end of the pump shaft 106, liquid is pumped into the pipe joint 1071 through the water inlet of the pipe joint 1071 and discharged through the water outlet. The function of the wheel sleeve 1062 is to gather the disturbing force generated during the rotation of the impeller 1061, making the pumping force of the impeller 1061 more stable. Since the inner magnetic sleeve 105 is suspended in the isolation sleeve 104, in order to make the inner magnetic sleeve 105 and the pump shaft 106 have stability and a point of force, a convex ring is centrally provided at one end of the isolation sleeve 104 close to the drive shaft 101, and one end of the pump shaft 106 is rotatably connected within the convex ring. A bearing sleeve 1042 is centrally provided at the front end of the isolation sleeve 104, and the pump shaft 106 is fixedly connected to the inner ring of the bearing sleeve 1042. In this embodiment, the convex ring and the bearing sleeve 1042 stabilize the pump shaft 106 without affecting the rotation of the pump shaft, providing a point of force for the pump shaft 106 and the inner magnetic sleeve 105.

[0046] Refer to Figure 6 , a port sealing piece is integrally provided at the front end of the protective sleeve 107. The port sealing piece is provided with a groove, and a sealing ring is placed in the groove. One end of the pipe joint 1071 is embedded in the groove and connected by bolts. This tight connection method can minimize the channels for sound leakage, thereby improving the sound insulation effect, and at the same time eliminating the possibility of liquid leakage.

[0047] Refer to Figure 3 and Figure 4 , in this embodiment, a sound insulation sleeve 205 is sleeved outside the protective sleeve 107. A cavity is provided between the sound insulation sleeve 205 and the protective sleeve 107, and the cavity is filled with sound insulation material. In this embodiment, the sound insulation sleeve 205 wraps around the protective sleeve 107, forming a cavity between the two and filled with sound insulation material, which can effectively block the noise generated during the operation of the magnetic pump from spreading outward and reduce the noise pollution to the surrounding environment; one end of the sound insulation sleeve 205 is attached to the outer surface of the port sealing piece, and the other end of the sound insulation sleeve 205 is provided with a plurality of connecting ears, and the connecting ears are fixed to the front end of the motor 100 by screws. This connection method can minimize the channels for sound leakage, thereby improving the sound insulation effect. It should be noted that both the output pipe 202 and the output pipe 202 penetrate through the sound insulation sleeve 205.

[0048] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope determined by the claims submitted for the present invention.
