Description

Technical Field

[0001] This utility model relates to the field of heat dissipation of shielded pumps, specifically a horizontal shielded pump with external circulation cooling. Background Technology

[0002] A canned motor pump is a seal-less pump, mainly composed of a pump body, impeller, stator, rotor, front and rear bearings, and thrust disc. Canned motor pumps can achieve self-stabilizing outlet pressure and also feature self-cooling. In industrial production, canned motor pumps are widely used in equipment such as air compressors, gas-liquid booster pumps, and vacuum pumps.

[0003] Most horizontal canned motor pumps on the market use internal circulation cooling devices for cooling. However, when conveying some high-temperature media, the heat dissipation rate inside the pump body is slow due to the high fluid temperature, resulting in poor heat dissipation of the motor inside the pump body and shortening the service life of the motor.

[0004] Therefore, a horizontal canned pump with external circulation cooling is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a horizontal shielded pump with external circulation cooling.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A horizontal shielded pump with external circulation cooling, comprising a shielded pump; a base is fixedly connected to the bottom of the shielded pump; a connecting pipe is connected to the outlet of the shielded pump; a cooling pipe is provided on the top of the base; the connecting pipe is connected to the cooling pipe; a heat exchange pipe is provided inside the cooling pipe; a top cover is slidably connected to the top of the cooling pipe; a motor is fixedly connected to the top of the top cover; a rotating rod is fixedly connected to the output end of the motor; a stirring rod is fixedly connected to the surface of the rotating rod; a bracket is fixedly connected to the surface of the cooling pipe; and the bracket is fixedly connected to the base. This step, by placing the connecting pipe on the outside of the shielded pump, allows the heated medium to flow to the outside through the connecting pipe, enabling faster heat dissipation as it flows through the connecting pipe. The heat exchange pipe carries away the heat inside the cooling pipe, thus cooling the medium inside the cooling pipe. The motor drives the stirring rod to rotate, agitating the medium inside the cooling pipe, promoting medium flow, breaking up temperature stratification, ensuring uniform temperature of the medium throughout the cooling pipe, improving the heat exchange efficiency with the surface of the heat exchange pipe, and accelerating the heat dissipation of the shielded pump.

[0007] Preferably, the cooling pipe and the surface of the top cover are both fixedly connected with connecting ears, and the connecting ears are connected by bolts. The inner side of the shielded pump is fixedly connected with a connecting frame, and the connecting frame is slidably connected to the rotating rod. This step, by setting several connecting ears and bolts, allows the top cover to be disassembled and assembled so that the rotating rod and stirring rod can be taken out for cleaning. At the same time, the inside of the cooling pipe can be inspected. The connecting frame can limit the bottom end of the rotating rod, improving the stability of the rotating rod inside the cooling pipe.

[0008] Preferably, the shielded pump is internally connected to a heat dissipation copper pipe, the side of the bracket is fixedly connected to a cooling fan, and the inner side of the bracket has an exhaust port. This step uses several heat dissipation copper pipes to dissipate heat from the bottom of the cooling pipe, and the cooling fan continuously blows air onto the heat dissipation copper pipe to increase the heat dissipation efficiency at the bottom of the cooling pipe.

[0009] Preferably, a filter screen is provided in the outlet hole of the cooling pipe, the bottom of the cooling pipe has a conical structure, and the bottom of the cooling pipe is connected to a drain pipe; in this step, impurities in the medium inside the cooling pipe will settle to the bottom of the cooling pipe, and opening the drain pipe can discharge the impurities inside the cooling pipe, reducing the burden of cleaning the inside of the cooling pipe.

[0010] Preferably, an observation window is provided on the front side of the cooling pipe, and a scale is provided on the surface of the observation window; this step allows the staff to observe the liquid level and cleanliness inside the cooling pipe through the observation window and the scale.

[0011] Preferably, a temperature detector is provided on the top of the top cover; this step allows the operator to observe the temperature inside the cooling pipe.

[0012] The advantages of this utility model are:

[0013] 1. The horizontal shielded pump with external circulation cooling described in this utility model, by placing the connecting pipe on the outside of the shielded pump, allows the heated medium to flow to the outside through the connecting pipe. When flowing through the connecting pipe, heat dissipation can be achieved more quickly. The heat exchange pipe can carry away the heat inside the cooling pipe, thereby cooling the medium inside the cooling pipe. The motor can drive the stirring rod to rotate, stirring the medium inside the cooling pipe, driving the medium to flow, breaking up temperature stratification, ensuring uniform temperature of the medium throughout the cooling pipe, improving the heat exchange efficiency with the surface of the heat exchange pipe, and accelerating the heat dissipation speed of the shielded pump.

[0014] 2. The horizontal shielded pump with external circulation cooling described in this utility model can be disassembled and assembled by setting several connecting ears and bolts, so as to remove the rotating rod and stirring rod for cleaning. At the same time, the inside of the cooling pipe can be inspected. The bottom end of the rotating rod can be limited by the connecting frame to improve the stability of the rotating rod inside the cooling pipe. Attached Figure Description

The internal heat of the cooling pipe 14 is stirred by the rotating rod 18 driven by the motor 17, which in turn drives the stirring rod 19 to stir the medium inside the cooling pipe 14. The medium is then discharged through the connecting pipe 13 on the other side and enters the interior of the shielded pump 1. This step, by placing the connecting pipe 13 on the outside of the shielded pump 1, allows the heated medium to flow to the outside through the connecting pipe 13, which can dissipate heat more quickly when flowing through the connecting pipe 13. The heat exchange tube 15 can carry away the heat inside the cooling pipe 14 to cool the medium inside the cooling pipe 14. The stirring rod 19 driven by the motor 17 can stir the medium inside the cooling pipe 14, drive the medium to flow, break the temperature stratification, ensure the uniform temperature of the medium inside the entire cooling pipe 14, improve the heat exchange efficiency with the surface of the heat exchange tube 15, and accelerate the heat dissipation of the shielded pump 1.

[0024] like Figures 3 to 5 As shown, connecting ears 21 are fixedly connected to the surfaces of the cooling pipe 14 and the top cover 16, and the connecting ears 21 are connected by bolts. A connecting frame 22 is fixedly connected to the inner side of the shielded pump 1, and the connecting frame 22 is slidably connected to the rotating rod 18. When it is necessary to disassemble or assemble the top cover 16 during operation, the bolts can be rotated to separate it from the connecting ears 21 on the surface of the top cover 16 and the rotating rod 18, and the top cover 16 can be pulled to separate it from the cooling pipe 14. The top cover 16 drives the motor 17 and the rotating rod 18 to move, so that the rotating rod 18 drives... The stirring rod 19 is removed from the interior of the cooling pipe 14, and at the same time, the bottom of the rotating rod 18 is separated from the connecting frame 22. The stirring rod 19 and the interior of the cooling pipe 14 can be inspected and cleaned. This step involves setting several connecting ears 21 and bolts to disassemble and assemble the top cover 16 so that the rotating rod 18 and the stirring rod 19 can be taken out for cleaning. At the same time, the interior of the cooling pipe 14 can be inspected. The connecting frame 22 can limit the bottom end of the rotating rod 18, improving the stability of the rotating rod 18 inside the cooling pipe 14.

[0025] like Figure 3 and Figure 4As shown, a heat dissipation copper pipe 31 is fixedly connected inside the shielded pump 1, and a cooling fan 32 is fixedly connected to the side of the bracket 110. An exhaust port is opened on the inner side of the bracket 110. During operation, the heat dissipation copper pipe 31 can carry away the heat from the bottom of the cooling pipe 14, thus dissipating heat from the bottom of the cooling pipe 14. The cooling fan 32 can continuously blow air onto the heat dissipation copper pipe 31 to dissipate heat. This step can dissipate heat from the bottom of the cooling pipe 14 through several heat dissipation copper pipes 31. The cooling fan 32 continuously blows air onto the heat dissipation copper pipe 31 to increase the heat dissipation efficiency of the bottom of the cooling pipe 14.

The bottom of the cooling pipe 14 is connected to the drain pipe 41. In this step, impurities in the medium inside the cooling pipe 14 will settle to the bottom of the cooling pipe 14. Opening the drain pipe 41 can discharge the impurities inside the cooling pipe 14, reducing the burden of cleaning the inside of the cooling pipe 14.

[0027] like Figure 2 As shown, an observation window 51 is provided on the front side of the cooling pipe 14, and a scale is provided on the surface of the observation window 51; this step allows the staff to observe the liquid level and cleanliness inside the cooling pipe 14 through the observation window 51 and the scale.

[0028] like Figure 2 and Figure 5 As shown, a temperature detector 61 is provided on the top of the top cover 16; this step allows the operator to observe the temperature inside the cooling pipe 14 through the temperature detector 61.

[0029] Working principle: The medium inside the canned pump 1 enters the cooling pipe 14 through the connecting pipe 13, causing the cooling pipe 14 to heat up. The heat inside the cooling pipe 14 is carried away by the flow of coolant inside the heat exchange pipe 15. The motor 17 drives the rotating rod 18 to rotate, which in turn drives the stirring rod 19 to rotate, stirring the medium inside the cooling pipe 14. The medium is then discharged through the connecting pipe 13 on the other side and enters the interior of the canned pump 1. When the top cover 16 needs to be disassembled, the bolts can be rotated to align it with the top cover 16 and the rotating rod 18. The connecting lug 21 is separated, and the top cover 16 can be pulled to separate it from the cooling pipe 14. The top cover 16 drives the motor 17 and the rotating rod 18 to move, so that the rotating rod 18 drives the stirring rod 19 out of the cooling pipe 14. At the same time, the bottom of the rotating rod 18 is separated from the connecting frame 22, so that the stirring rod 19 and the inside of the cooling pipe 14 can be inspected and cleaned. The heat dissipation copper pipe 31 can carry away the heat from the bottom of the cooling pipe 14, and dissipate heat from the bottom of the cooling pipe 14. The cooling fan 32 can continuously blow air to dissipate heat from the cooling copper pipe 31.
