Description

Technical Field

[0001] This utility model relates to the field of shielded pump technology, specifically a shielded pump with heat dissipation function. Background Technology

[0002] A conventional centrifugal pump is driven by connecting the pump impeller shaft to the motor shaft via a coupling, causing the impeller and motor to rotate together. A canned motor pump, on the other hand, is a sealless pump in which both the pump and the drive motor are sealed within a pressure vessel filled with the pumped medium. This pressure vessel has only a static seal, and a set of wires provides the rotating magnetic field to drive the rotor.

[0003] In existing canned motor pumps, the motor and impeller are assembled together, so the motor is sealed and protected inside the pump. This results in the motor being unable to dissipate heat in a sealed space. As the motor operates in a high-temperature environment for a long time, the service life of the internal parts will be shortened. Therefore, those skilled in the art have provided a canned motor pump with heat dissipation function to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a shielded pump with heat dissipation function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shielded pump with heat dissipation function, comprising an installation pipe, an inlet pipe connected to one side of the installation pipe, a plurality of connecting blocks arranged in a ring array on the inner wall of the inlet pipe, and a shielding sleeve fixedly connected to the side of the plurality of connecting blocks that are close to each other, a dual-axis motor fixedly embedded in the shielding sleeve, a converter rod fixedly sleeved on one output shaft of the dual-axis motor, the converter rod penetrating the shielding sleeve and extending to the outside of the shielding sleeve, a rotating rod fixedly sleeved on the other output shaft of the dual-axis motor, one end of the rotating rod penetrating the shielding sleeve and fixedly connected to an impeller, an outlet pipe connected to the top of the inlet pipe, a partition plate fixedly connected to the inner wall of the inlet pipe, the rotating rod penetrating the partition plate, and two arc-shaped holes symmetrically opened on the upper part of the partition plate, a plurality of heat-conducting pipes arranged in a ring array on the outer wall of the dual-axis motor, and the plurality of heat-conducting pipes penetrating the shielding sleeve and the installation pipe and extending to the outside of the installation pipe.

[0006] As a further improvement of this utility model: the partition plate is connected to the liquid outlet pipe, and the impeller is located below the liquid outlet pipe.

[0007] As a further improvement of this utility model: the bottom of the liquid inlet pipe and the mounting pipe are fixedly connected to the same base, and the impeller and the converter rod are located on both sides of the shielding sleeve.

[0008] As a further embodiment of this utility model: multiple heat-conducting sheets are arranged in a ring on the outer side of the shielding sleeve, and the multiple heat-conducting sheets are respectively fixedly embedded on multiple heat-conducting pipes, with the multiple heat-conducting sheets located between the mounting pipe and the shielding sleeve.

[0009] As a further embodiment of this utility model: a connecting ring is fixedly connected to the inner wall of the liquid outlet pipe, a sealing plug is connected through the connecting ring, a top cover is fixedly connected to the top of the sealing plug, and multiple tension springs are arranged in a circular array at the bottom of the top cover, with the bottom of the multiple tension springs fixedly connected to the top of the connecting ring.

[0010] As a further improvement of this utility model: the rear of the impeller is attached to one side of the partition plate, and part of the heat conduction pipe passes through the connecting block and extends to the outside of the base.

[0011] As a further improvement of this utility model: the outlet of the liquid outlet pipe faces upward, and the two arc-shaped holes of the partition plate are arranged symmetrically from top to bottom.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Because the converter rod rotates in the opposite direction to the impeller, it generates a forward thrust, which transports the liquid in the mounting tube through the arc-shaped hole above the partition plate to the outlet tube. At this time, the liquid generates an upward thrust, pushing the sealing plug out of the connecting ring. The connecting ring is then released from its seal, and liquid flows through the connecting ring and is discharged through the outlet tube. When the sealing plug is under force, multiple tension springs pull the top cover down with a downward force. After the top cover falls, it drives the sealing plug down to reseal inside the sealing plug. This prevents the backflow of liquid in the outlet tube. The heat from the dual-shaft motor can be transferred to multiple heat-conducting pipes. Heat-conducting plates are also installed on the heat-conducting pipes to increase the contact with the liquid flowing in the mounting tube. This allows the heat-conducting pipes and multiple heat-conducting plates to transfer more heat into the liquid in the mounting tube. When the liquid is discharged from the outlet tube, it carries away the heat from the heat-conducting pipes and heat-conducting plates, thus completing the heat dissipation of the dual-shaft motor.

[0014] This invention is simple to use. It uses multiple heat-conducting pipes and heat-conducting plates to conduct heat into the liquid flowing inside the installation pipe for heat dissipation. This can utilize the principle of heat conduction to dissipate heat from the dual-axis motor. The outlet pipe is equipped with a sealing plug and multiple tension springs to prevent liquid from flowing back into the installation pipe when the dual-axis motor is stopped.

[0023] Please see Figures 1-6 In this embodiment of the present invention, a shielded pump with heat dissipation function includes an installation pipe 2. One side of the installation pipe 2 is connected to an inlet pipe 3. Multiple connecting blocks 9 are arranged in a ring array on the inner wall of the inlet pipe 3. The same shielding sleeve 8 is fixedly connected to the side of the multiple connecting blocks 9 that are close to each other. A dual-axis motor 15 is fixedly embedded inside the shielding sleeve 8. A converter rod 11 is fixedly sleeved on one output shaft of the dual-axis motor 15, and the converter rod 11 penetrates the shielding sleeve 8 and extends outside the shielding sleeve 8. The dual-axis motor 15... A rotating rod 13 is fixedly sleeved on another output shaft, and one end of the rotating rod 13 passes through the shielding sleeve 8 and is fixedly connected to an impeller 14. The top of the liquid inlet pipe 3 is connected to the liquid outlet pipe 4. A partition plate 17 is fixedly connected to the inner wall of the liquid inlet pipe 3. The rotating rod 13 passes through the partition plate 17, and two arc-shaped holes 16 are symmetrically opened on the upper part of the partition plate 17. Multiple heat conduction pipes 5 are arranged in a ring array on the outer wall of the dual-axis motor 15, and the multiple heat conduction pipes 5 pass through the shielding sleeve 8 and the mounting pipe 2 and extend to the outside of the mounting pipe 2.

[0024] In this embodiment, the partition plate 17 is connected to the liquid outlet pipe 4, and the impeller 14 is located below the liquid outlet pipe 4.

[0025] In this embodiment, the bottom of the liquid inlet pipe 3 and the mounting pipe 2 are fixedly connected to the same base 1, and the impeller 14 and the converter rod 11 are located on both sides of the shielding sleeve 8.

[0026] In this embodiment, a plurality of heat-conducting sheets 12 are arranged in a ring on the outer side of the shielding sleeve 8, and the plurality of heat-conducting sheets 12 are respectively fixedly embedded on a plurality of heat-conducting pipes 5, and the plurality of heat-conducting sheets 12 are located between the mounting pipe 2 and the shielding sleeve 8.

[0027] In this embodiment, a connecting ring 10 is fixedly connected to the inner wall of the liquid outlet pipe 4, and a sealing plug 6 is connected through the connecting ring 10. A top cover 7 is fixedly connected to the top of the sealing plug 6, and a plurality of tension springs 18 are arranged in a ring array at the bottom of the top cover 7, and the bottom of the plurality of tension springs 18 is fixedly connected to the top of the connecting ring 10.

[0028] In this embodiment, the rear of the impeller 14 is attached to one side of the partition plate 17, and part of the heat pipe 5 passes through the connecting block 9 and extends to the outside of the base 1.

[0029] In this embodiment, the outlet of the liquid outlet pipe 4 faces upward, and the two arc-shaped holes 16 of the partition plate 17 are arranged symmetrically from top to bottom.

[0030] The working principle of this utility model is as follows: Starting the dual-shaft motor 15 can drive the converter rod 11 and the rotating rod 13 to rotate respectively. The converter rod 11 and the rotating rod 13 rotate in opposite directions. When the rotating rod 13 rotates, it can drive the impeller 14 to draw liquid into the installation pipe 2 through the inlet pipe 3. The liquid in the installation pipe 2 will enter the installation pipe 2 through the arc-shaped hole 16 on the partition plate 17. At this time, the liquid will reach the position of the converter rod 11 through the connecting block 9. At this time, the liquid will fill the entire installation pipe 2. Since the rotation direction of the converter rod 11 is opposite to that of the impeller 14, the converter rod 11 will generate a forward thrust, thereby transporting the liquid in the installation pipe 2 through the arc-shaped hole 16 above the partition plate 17 to the outlet pipe 4. At this time, the liquid will generate an upward thrust to seal the plug. When the connecting ring 10 is pushed out of the socket, the sealing of the connecting ring 10 is released, and liquid flows through the connecting ring 10 and is discharged through the outlet pipe 4. When the sealing plug 6 is under force, multiple tension springs 18 will pull the top cover 7 down by downward force. After the top cover 7 falls, it will drive the sealing plug 6 down and reseal it inside the sealing plug 6. This can prevent the backflow of liquid in the outlet pipe 4. The heat of the dual-axis motor 15 can be introduced to multiple heat-conducting pipes 5. Heat-conducting plates 12 are also provided on the heat-conducting pipes 5 to increase the contact with the liquid flowing in the mounting pipe 2. This allows the heat-conducting pipes 5 and multiple heat-conducting plates 12 to introduce more heat into the liquid in the mounting pipe 2. When the liquid is discharged from the outlet pipe 4, it can take away the heat of the heat-conducting pipes 5 and heat-conducting plates 12, which can complete the heat dissipation of the dual-axis motor 15.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
