Description

Technical Field

[0001] The present invention relates to the technical field of magnetic pumps, and particularly to a magnetic pump structure with a self-cooling function. Background Art

[0002] A magnetic pump is a power device for conveying. This device mainly consists of several parts such as a pump head, a magnetic drive (magnetic cylinder), a motor, and a connecting base plate. The magnetic drive of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic substances, driving the inner magnetic rotor connected to the impeller to rotate synchronously, realizing the non-contact synchronous transmission of power, and converting the easily leaking dynamic seal structure into a zero-leakage static seal structure.

[0003] When the current magnetic pump structure is in use, under low-temperature working conditions, when the temperature of the conveyed liquid is less than 100 degrees, the pump body often uses a medium for cooling, adding a cold liquid into the isolation sleeve and using heat-conducting fins for cooling. This results in poor fluidity of the liquid and a poor heat dissipation effect during long-term operation. When working under high-temperature conditions, an externally separately provided power device is used to convey the medium to circulate in the pump to take away heat, and cooling water or circulating liquid is introduced for cooling, and the power of the pump body itself cannot be fully utilized. This will lead to an increase in the cost of the additional equipment and an increase in the space occupied by the pump body.

[0004] In view of the above problems, a magnetic pump structure with a self-cooling function is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a magnetic pump structure with a self-cooling function. By using this device for operation, the problems in the above background are solved. When the current magnetic pump structure is in use, under low-temperature working conditions, when the temperature of the conveyed liquid is less than 100 degrees, the pump body often uses a medium for cooling, adding a cold liquid into the isolation sleeve and using heat-conducting fins for cooling. This results in poor fluidity of the liquid and a poor heat dissipation effect during long-term operation. When working under high-temperature conditions, an externally separately provided power device is used to convey the medium to circulate in the pump to take away heat, and cooling water or circulating liquid is introduced for cooling, and the power of the pump body itself cannot be fully utilized. This will lead to an increase in the cost of the additional equipment and an increase in the space occupied by the pump body.

[0006] To achieve the above object, the present invention provides the following technical solution: A magnetic pump structure with a self-cooling function, including a main pump and a cooling mechanism. A power motor is arranged behind the main pump, and a bracket sleeve is arranged in the middle of the front end of the power motor. The cooling mechanism for automatic cooling and temperature reduction is arranged in the middle of the inner side of the bracket sleeve. The cooling mechanism includes a rotating shaft, an installation cover, a first installation sleeve, a first impeller, a fixing screw head, a second installation sleeve, a second impeller, a limiting rod and a liquid outlet. An installation cover is installed in the middle of the rear of the rotating shaft, and a first installation sleeve is arranged in the middle of the surface of the rotating shaft. A first impeller is fixed to the outside of the first installation sleeve, and a fixing screw head is installed at the front end of the surface of the first installation sleeve. A second installation sleeve is arranged behind the first installation sleeve, and a second impeller is fixed to the outside of the second installation sleeve. Limiting rods are arranged on the front and rear surfaces of the second installation sleeve. A liquid outlet is arranged below one side of the outside of the bracket sleeve.

[0007] Further, the power motor is rotationally connected to the rotating shaft through the installation cover, and the first installation sleeve and the first impeller are fixedly connected to the rotating shaft through the fixing screw head. The second impeller is slidably connected to the rotating shaft through the second installation sleeve.

[0008] Further, a linkage mechanism for hierarchical liquid supply cooling is arranged on the inner side of the front end of the cooling mechanism. The linkage mechanism includes an installation groove and a telescopic sleeve. A telescopic sleeve is installed in the middle of the inner side of the installation groove.

[0009] Further, the linkage mechanism further includes a connecting spring and a clamping head. A connecting spring is arranged on the outside of the telescopic sleeve, and a clamping head is arranged at the top of the connecting spring.

[0010] Further, the linkage mechanism further includes a mating card slot. Mating card slots are annularly distributed on the inner surface of the second installation sleeve.

[0011] Further, the clamping head is elastically connected to the rotating shaft through the connecting spring, and the rotating shaft is clamped to the second installation sleeve through the clamping head and the mating card slot.

[0012] Further, a liquid guiding mechanism for distributed cooling is arranged on the outer surface of the power motor. The liquid guiding mechanism includes a wrapping sleeve and a liquid outlet conduit. A liquid outlet conduit is connected to the lower side of one side of the wrapping sleeve, and the liquid outlet is communicated with the liquid outlet conduit and the wrapping sleeve.

[0013] Further, the liquid guiding mechanism further includes heat conducting sheets and flow holes. Heat conducting sheets are arranged on the surface of the wrapping sleeve, and flow holes are opened on the bottom surface of the heat conducting sheets.

[0014] Furthermore, the liquid guiding mechanism also includes a liquid return conduit, a circulation cavity, and a liquid storage cavity. The liquid return conduit is connected to the lower part of the other side of the wrapping sleeve, and a circulation cavity is arranged in the middle part of the inner side of the wrapping sleeve, and the liquid storage cavity is arranged at the front end of the liquid return conduit.

[0015] Furthermore, the wrapping sleeve is connected with the liquid return conduit, the liquid storage chamber and the bracket sleeve, and an external magnetic cylinder is installed at the front end of the rotating shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention, through the cooperation between the various parts of the cooling mechanism, breaks the relatively static state that the coolant may originally exist in when the main pump is working, and realizes the circulation of the coolant. Compared with natural convection, it can more quickly take away the heat generated by the operation of the external magnetic cylinder and other components, effectively reduce the temperature of the components, and thus achieve a better heat dissipation effect. At the same time, the first impeller and the second impeller rely on the rotational force of the main pump itself when it is working, which can realize the self-cooling of the main pump, avoid the energy consumption caused by the addition of external power equipment such as cooling pumps, reduce the overall operating cost, improve the energy utilization rate, and help save the space occupied by the outside and the equipment and energy consumed separately.

[0018] 2. The present invention, through the coordination between the various parts of the linkage mechanism, can utilize the second impeller and the first impeller to perform multi-stage synchronous pumping of the coolant when the main pump rotates at high power and high speed. The multi-stage impeller can accelerate and decelerate the coolant multiple times in the circulation path, enhance the turbulence effect, and strengthen the heat exchange. At the same time, when the rotating shaft rotates at a low speed, the centrifugal force is small, so that the first impeller can rotate independently, and different stages of impellers can produce different intensities of stirring on the coolant, which can more fully promote the circulation of the coolant and improve the heat dissipation efficiency.

[0019] 3. The present invention can transfer the coolant pumped out of the bracket sleeve to the wrapping sleeve through the cooperation between the various parts of the liquid guiding mechanism, and can take away the heat of the power motor when the coolant flows, thereby realizing auxiliary heat dissipation of the power motor, which is beneficial to improving the use effect and cooling effect of the main pump. At the same time, when the coolant uses the pipeline for large-scale reflux, there is also a certain time in the process to discharge the heat absorbed by the coolant, so as to ensure the cooling effect of the coolant in the subsequent circulation.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] To solve the technical problem that the existing technology cannot utilize the power of the pump body to achieve automatic cooling, such as Figures 1-7As shown in the figure, the following preferred technical solutions are provided: A magnetic pump structure with a self-cooling function, including a main pump 1 and a cooling mechanism 4 arranged inside the main pump 1. A power motor 3 is arranged behind the main pump 1, and a support sleeve 2 is arranged in the middle of the front end of the power motor 3. The cooling mechanism 4 includes a rotating shaft 401 rotatably connected to the power motor 3. An installation cover 402 is installed in the middle of the rear of the rotating shaft 401. By using the installation cover 402 that is installed by screwing up and down, the output shaft of the power motor 3 can be installed together with the rotating shaft 401, and the power motor 3 is rotatably connected to the rotating shaft 401 through the installation cover 402;

[0032] A first installation sleeve 403 is arranged in the middle of the surface of the rotating shaft 401. A first impeller 404 is integrally arranged on the outside of the first installation sleeve 403, and a fixing screw head 405 is installed at the front end of the surface of the first installation sleeve 403. The first installation sleeve 403 and the first impeller 404 are fixedly connected to the rotating shaft 401 through the fixing screw head 405. Through the fixing screw head 405, the first installation sleeve 403 and the first impeller 404 can be installed and fixed on the rotating shaft 401, so that the first impeller 404 can rotate together with the rotating shaft 401;

[0033] A second installation sleeve 406 is arranged behind the first installation sleeve 403, and a second impeller 407 is integrally arranged on the outside of the second installation sleeve 406. Limiting rods 408 are arranged on the front and rear surfaces of the second installation sleeve 406. The second impeller 407 is slidably connected to the rotating shaft 401 through the second installation sleeve 406. The limiting rods 408 are threadedly installed on the rotating shaft 401, and the limiting rods 408 limit the front and rear positions of the second installation sleeve 406. While ensuring that the second installation sleeve 406 can slide on the rotating shaft 401, the second installation sleeve 406 will not slide back and forth on the surface of the rotating shaft 401. An outlet 409 is arranged below one side of the outside of the support sleeve 2;

[0034] The power output of the power motor 3 can provide power for the impeller rotation of the main pump 1 itself during operation. Through the installed first installation sleeve 403, the first impeller 404, the second installation sleeve 406 and the second impeller 407, when the power motor 3 drives the rotating shaft 401 to rotate at a low speed and a high speed, the rotating shaft 401 can rotate together, so that when the first impeller 404 and the second impeller 407 rotate, a stirring centrifugal force can be generated on the coolant introduced into the bracket sleeve 2 of the main pump 1 itself. The liquid is thrown to the outer edges of the two sets of impellers under the action of the centrifugal force, thereby obtaining kinetic energy and pressure energy, so that the coolant can be cooled by the outlet 40 9 and the externally connected circulation pipe to flow. When the main pump 1 transports liquid with a lower temperature, the relatively static state that the coolant may have originally existed is broken, and the circulation flow of the coolant is realized. Compared with natural convection, the heat generated by the operation of the external magnetic cylinder 7 and other components can be taken away more quickly, and the temperature of the components can be effectively reduced, thereby achieving a better heat dissipation effect. At the same time, the first impeller 404 and the second impeller 407 rely on the rotational force of the main pump 1 itself when it is working, which can realize the self-cooling of the main pump 1, avoiding the use of external separately set power equipment to transport the medium to circulate in the pump to take away the heat, which is beneficial to saving the space occupied by the outside and the equipment and energy consumed separately.

[0035] In order to solve the technical problem of poor cooling effect of the pump body when running at high speed, such as Figures 1-7 As shown, the following preferred technical solutions are provided: a linkage mechanism 5 is provided at the inner side of the front end of the cooling mechanism 4, the linkage mechanism 5 includes a mounting groove 501 provided on the surface of the rotating shaft 401, a telescopic sleeve 502 is installed at the inner middle part of the mounting groove 501, a connecting spring 503 is provided on the outside of the telescopic sleeve 502, and a snap-fit ​​head 504 is provided on the top of the connecting spring 503, the snap-fit ​​head 504 is elastically connected to the rotating shaft 401 through the connecting spring 503, the inner surface of the second mounting sleeve 406 is annularly distributed with matching slots 505, the rotating shaft 401 is snap-fitted with the second mounting sleeve 406 through the matching slots 504 and the matching slots 505, and the linkage mechanism 5 can be used to perform graded pumping of coolant according to the speed of the running speed of the main pump 1, so that the heat dissipation and cooling effect can be guaranteed even when working at high speed;

[0036] Through the telescopic sleeve 502 and the connecting spring 503, when the rotating shaft 401 rotates at a high speed, a large centrifugal force will be generated. At this time, the centrifugal force will cause the connecting spring 503 and the telescopic sleeve 502 to expand outward from the installation groove 501. The expanded telescopic sleeve 502 will cause the engaging head 504 to extend into the mating clamping groove 505, so that the engaging head 504 and the second installation sleeve 406 are clamped together. At this time, the rotational force of the rotating shaft 401 will be transmitted to the second installation sleeve 406 by means of the telescopic sleeve 502 and the engaging head 504, so that the second installation sleeve 406 and the second impeller 407 rotate together with the rotating shaft 401. Thus, when the main pump 1 rotates at a high power and high speed, the second impeller 407 and the first impeller 404 can be used to pump the coolant synchronously in multiple stages. The multiple-stage impellers can accelerate and decelerate the coolant multiple times in the circulation path, enhance the turbulent flow effect, and strengthen the heat exchange. At the same time, when the rotating shaft 401 rotates at a low speed, the centrifugal force is small, the engaging head 504 is separated from the mating clamping groove 505, and the second impeller 407 loses the ability to rotate synchronously with the rotating shaft 401, so that the first impeller 404 rotates independently, realizing different levels of impellers to stir the coolant with different intensities, which can more fully promote the coolant circulation and improve the heat dissipation efficiency.

[0037] To solve the technical problem of limited cooling and temperature reduction range, as Figures 1-3 well as Figure 8 and Figure 9 shown, the following preferred technical solutions are provided: A liquid guiding mechanism 6 for distributing cooling is arranged on the outer surface of the power motor 3. The liquid guiding mechanism 6 includes a wrapping sleeve 601 arranged above the outside of the power motor 3. A liquid outlet conduit 602 is connected to the lower side of one side of the wrapping sleeve 601, and the liquid outlet 409 is communicated with the liquid outlet conduit 602 and the wrapping sleeve 601. The liquid outlet conduit 602 and the liquid outlet 409 are connected by a flange structure, and the coolant flowing out of the support sleeve 2 can be circulated into the wrapping sleeve 601. Heat conducting fins 603 are arranged on the surface of the wrapping sleeve 601. The heat conducting fins 603 and the wrapping sleeve 601 are both made of heat conducting metal materials, and flow holes 606 are opened on the bottom surface of the heat conducting fins 603. A liquid return conduit 604 is connected to the lower side of the other side of the wrapping sleeve 601, and a circulation cavity 605 is arranged in the middle of the inner side of the wrapping sleeve 601. A liquid storage cavity 607 is arranged at the front end of the liquid return conduit 604. The wrapping sleeve 601 is communicated with the liquid return conduit 604, the liquid storage cavity 607 and the support sleeve 2. An outer magnetic cylinder 7 is installed at the front end of the rotating shaft 401. Through the circulation cavity 605 and the flow holes 606, the coolant can be circulated in the wrapping sleeve 601 and flows into the liquid storage cavity 607 through the liquid return conduit 604. The output end of the liquid storage cavity 607 is connected to the support sleeve 2, and an S-shaped flow channel and heat dissipating fins are arranged in the liquid storage cavity 607, so that heat dissipation treatment can be carried out when the coolant flows back;

[0038] Through the liquid outlet conduit 602, the coolant pumped out by the support sleeve 2 is transferred into the wrapping sleeve 601. The wrapping sleeve 601 that fits on the surface of the power motor 3, in cooperation with the heat conducting fins 603, can carry away the heat of the power motor 3 when the coolant flows, realizing the auxiliary heat dissipation of the power motor 3, which is beneficial to improving the use effect and cooling effect of the main pump 1. At the same time, when the coolant flows back in a large range through the pipeline, there is also a certain time during the process to discharge the heat absorbed by the coolant to ensure the cooling effect of the coolant in the subsequent cycle.

[0039] When using this magnetic pump structure with self-cooling function, first, through the mounting cover 402 installed by screwing up and down, the output shaft of the power motor 3 can be installed together with the rotating shaft 401. Subsequently, through the fixing screw head 405, the first mounting sleeve 403 and the first impeller 404 can be installed and fixed on the rotating shaft 401, enabling the first impeller 404 to rotate together with the rotating shaft 401. Then, through the power output of the power motor 3, power can be provided for the rotation of the impeller of the main pump 1 itself during operation.

[0040] Furthermore, through the first mounting sleeve 403, the first impeller 404, the second mounting sleeve 406, and the second impeller 407, when the power motor 3 drives the rotating shaft 401 to rotate at low speed and high speed subsequently, they can rotate together with the rotating shaft 401. Thus, when the first impeller 404 and the second impeller 407 rotate, a stirring centrifugal force can be generated on the coolant introduced into the support sleeve 2 of the main pump 1 itself. Under the action of the centrifugal force, the liquid flows through the liquid outlet 409 and the externally connected flow pipe. At this time, through the telescopic sleeve 502 and the connecting spring 503, when the rotating shaft 401 rotates at high speed, a large centrifugal force will be generated. At this time, the centrifugal force will cause the connecting spring 503 and the telescopic sleeve 502 to expand outward from the mounting groove 501. The expanded telescopic sleeve 502 will cause the engaging head 504 to extend into the mating card slot 505, making the engaging head 504 engage with the second mounting sleeve 406, enabling the second impeller 407 to rotate together with the rotating shaft 401. When the main pump 1 rotates at high power and high speed, the second impeller 407 and the first impeller 404 are used to pump the coolant synchronously in multiple stages. At the same time, when the rotating shaft 401 rotates at low speed, the centrifugal force is small, the engaging head 504 separates from the mating card slot 505, and the second impeller 407 loses the ability to rotate synchronously with the rotating shaft 401, enabling the first impeller 404 to rotate independently.

[0041] At this time, through the flow cavity 605 and the flow holes 606, by means of the transfer of the connection between the liquid outlet conduit 602 and the liquid outlet 409, the coolant can flow in the wrapping sleeve 601, and then flow into the liquid storage cavity 607 through the liquid return conduit 604. The output end of the liquid storage cavity 607 is connected to the support sleeve 2, and finally, the liquid storage cavity 607 returns the coolant to the support sleeve 2.
