Description

Technical Field

[0001] The present application relates to the technical field of pipeline pumps, and in particular to a vertical pipeline pump for conveying high-solid-content, high-viscosity non-Newtonian fluids. Background Art

[0002] A pipeline pump is a type of single-suction single-stage or multi-stage centrifugal pump with a vertical structure. Because its inlet and outlet are in the same straight line and have the same inlet and outlet diameters, it resembles a section of pipe and can be installed at any position in the pipe. Therefore, it is named a pipeline pump, also known as a booster pump.

[0003] In the field of coal chemical industry, especially in the coal gasification line, the medium transported by the main pump is mostly high-solid and high-viscosity coal slurry. Coal slurry is a non-Newtonian fluid with poor fluidity. Cavitation often occurs when the main pump cannot smoothly inhale the medium, resulting in main pump vibration, low efficiency and other problems. At this time, it is particularly important to provide the main pump with a stable inlet pressure. The pipeline pump, also known as a booster pump, is used to provide a stable inlet pressure for the main pump to prevent the main pump from cavitation, or to compensate for the performance defect of the poor suction capacity of the main pump, to ensure the smooth operation of the main pump, optimize the operating conditions of the main pump, and extend the service life of the main pump.

[0004] A pipeline pump usually includes a motor bracket, a motor, a pump body and an impeller. The motor bracket is fixedly connected to the pump body, the motor is fixedly connected to the motor bracket, and the impeller is rotatably arranged in the pump body. The output shafts of the impeller and the motor are coaxially fixedly connected, so that after the motor is started, the impeller can be driven to rotate, thereby discharging the fluid sucked in from the inlet from the outlet to achieve a pressurization function. When a pipeline pump is used to transport a high-solid content, high-viscosity fluid, the impeller of the pump body will be subject to greater resistance, thereby increasing the load of the motor, and the motor will generate more heat, which is not conducive to the normal operation of the motor. Summary of the invention

[0005] In order to enhance the heat dissipation effect of the motor on the pipeline pump and ensure the normal operation of the pipeline pump, the present application provides a vertical pipeline pump for conveying high-solid content, high-viscosity non-Newtonian fluid.

[0006] The present application provides a vertical pipeline pump for conveying high-solid content, high-viscosity non-Newtonian fluids using the following technical solutions: A vertical pipeline pump for conveying high-solid content, high-viscosity non-Newtonian fluid, comprising: Pump body; An impeller, the impeller being rotatably disposed in the pump body; A motor bracket, wherein the motor bracket is fixedly arranged on the pump body; A motor, wherein the motor is fixedly connected to a motor bracket, and an output shaft of the motor is coaxially fixedly connected to an impeller; A cooling component, the cooling component includes a water pump, a liquid storage ring, a lower connecting ring, an upper connecting ring, a cooling pipe, a radiator and a fan, the water pump, the liquid storage ring and the lower connecting ring are all arranged on the motor bracket, the liquid storage ring, the lower connecting ring and the upper connecting ring are all provided with a cavity for accommodating coolant, the water pump is arranged between the liquid storage ring and the lower connecting ring, a plurality of cooling pipes are provided and are arranged in a ring around the motor, the cooling pipes are fixedly connected between the lower connecting ring and the upper connecting ring, the radiator is arranged between the upper connecting ring and the liquid storage ring, and the fan is arranged on the outside of the radiator.

[0007] By adopting the above technical scheme, in the working state, the coolant can circulate in the cooling pipe, and the coolant can exchange heat with the motor, thereby taking away the heat generated by the motor, which helps to enhance the heat dissipation effect of the motor; since there are multiple cooling pipes and they are arranged in a ring-shaped interval, not only can water cooling be performed through the cooling pipe, but the outer wall of the motor can also be fully in contact with the outside air, and air cooling can be performed while water cooling, thereby enhancing the heat dissipation effect; in addition, the motor will vibrate when it is working. Since the cooling pipe and the outer wall of the motor are against each other, the vibration generated when the motor is working will be transmitted to the cooling pipe, causing the cooling pipe to vibrate as well, thereby shaking off impurities such as scale adhering to the inner wall of the cooling pipe, which helps to ensure the heat exchange efficiency between the cooling pipe and the motor.

[0008] Optionally, a thermal pad is provided on the outer wall of the cooling pipe for abutting against the outer wall of the motor.

[0009] By adopting the above technical solution, the thermal pad can be in close contact with the outer wall of the motor, which helps to improve the heat exchange efficiency between the coolant and the motor, thereby enhancing the heat dissipation effect of the motor.

[0010] Optionally, a cleaning assembly is provided in the cooling tube, and the cleaning assembly includes a support rod, a cleaning member and an inner ring. The support rod is coaxially rotatably provided in the cooling tube, the cleaning member is fixedly provided on the support rod, and a side of the cleaning member away from the support rod abuts against an inner wall of the cooling tube. The inner ring is coaxially fixedly connected to the support rod, and a driving assembly for driving the inner ring to rotate is provided outside the cooling tube.

[0011] By adopting the above technical solution, the driving component drives the inner ring to rotate, the inner ring can drive the support rod to rotate, and the support rod drives the cleaning member to rotate, so that the cleaning member can brush off impurities such as scale adhering to the inner wall of the cooling pipe, thereby reducing the impact of the deposited scale on the heat exchange efficiency of the cooling pipe, which helps to ensure the heat dissipation effect; in addition, the vibration transmitted to the cooling pipe by the motor can make the cleaning member vibrate, thereby helping to vibrate off the impurities on the cleaning member, thereby ensuring the cleaning effect of the cleaning member.

[0012] Optionally, the cleaning member is a brush bristle, and the brush bristles are arranged along the radial direction of the cooling tube, and a plurality of the brush bristles are arranged along the length direction of the support rod.

[0013] By adopting the above technical solution, the bristles can brush off impurities such as scale on the inner wall of the cooling pipe as the support rod rotates, thereby cleaning the inner wall of the cooling pipe.

[0014] Optionally, the cleaning member is a scraper, and a plurality of scrapers are provided and staggered along the length direction of the support rod.

[0015] By adopting the above technical solution, the scraper can scrape off impurities such as scale on the inner wall of the cooling pipe as the support rod rotates, thereby cleaning the inner wall of the cooling pipe.

[0016] Optionally, the scraper is arranged at an angle.

[0017] By adopting the above technical solution, since multiple scrapers are arranged at intervals and each scraper is arranged in a twisted and inclined shape, multiple scrapers can together form a spiral structure. When the support rod drives the scraper to rotate, the scraper has a pushing effect on the coolant in the cooling pipe, thereby accelerating the flow of the coolant in the cooling pipe, which can accelerate the cooling of the coolant and help enhance the heat dissipation effect of the motor.

[0018] Optionally, the driving assembly includes an outer ring, a gear ring, a gear, a first magnetic member and a second magnetic member. There are multiple outer rings, each of which corresponds to an inner ring. The outer ring is coaxially rotatable on the outer wall of the cooling tube, and the outer ring and the inner ring are located at the same height of the cooling tube. The gear ring is rotatably set on the motor bracket. There are multiple gears, each of which corresponds to an outer ring. The gear is coaxially fixedly connected to the outer wall of the outer ring, and the gear is meshed with the gear ring. The first magnetic member is fixedly connected to the inner ring, and the second magnetic member is fixedly connected to the outer ring. When the first magnetic member is on the side close to the second magnetic member, the magnetic poles of the first magnetic member and the second magnetic member on the side close to each other are in opposite directions.

[0019] By adopting the above technical solution, the gear ring can drive the gear to rotate when it rotates, and the gear drives the corresponding outer ring to rotate. Since the magnetic poles of the first magnetic member and the second magnetic member on the side close to each other are in opposite directions, when the first magnetic member and the second magnetic member are located on the side close to each other, the first magnetic member and the second magnetic member tend to attract each other. Therefore, when the second magnetic member on the outer ring rotates, the first magnetic member on the inner ring can rotate along with it, so that the inner ring can rotate along with the rotation of the outer ring. When the inner ring rotates, it can drive the support rod to rotate, and the support rod drives the cleaning member to rotate, thereby achieving cleaning of the inner wall of the cooling tube.

[0020] Optionally, a first mounting groove is formed on the inner ring, the first magnetic member is fixedly connected in the first mounting groove, and an outer wall of the inner ring and an inner wall of the cooling tube are spaced apart.

[0021] By adopting the above technical solution, the inner ring and the cooling tube are spaced apart, so that the first magnetic part on the inner ring and the inner wall of the cooling tube are spaced apart. The attraction force between the first magnetic part and the second magnetic part will not generate resistance to the rotation of the inner ring and the first magnetic part, and the resistance encountered by the first magnetic part during rotation can be reduced, which helps the first magnetic part and the inner ring to rotate smoothly.

[0022] Optionally, a guide frame is provided on the outer side of the radiator, a guide ring is fixedly connected to one side of the guide frame, a plurality of guide pipes are provided on the guide ring, a wind shield is provided on the gear ring, and the opening of the guide pipe faces the wind shield.

[0023] By adopting the above technical solution, when the fan blows air to the radiator, the blown wind can also flow into the guide frame and the guide ring in sequence, and then blown out from the guide pipe. The guide pipe is directed toward the wind shield, so the wind blown out of the guide pipe can drive the wind shield to rotate, thereby causing the gear ring to rotate. Therefore, the rotation of the gear ring does not require an additional power source, and is therefore more energy-efficient.

[0024] Optionally, the wind shield is provided in plurality and arranged in a circular array.

[0025] By adopting the above technical solution, the contact area between the wind blown out by the guide pipe and the wind shield can be increased, so that the gear ring can be more easily rotated under the action of wind force.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Coolant circulates in the cooling pipe, which can exchange heat with the motor, thereby taking away part of the heat generated by the motor, helping to accelerate the heat dissipation of the motor, thereby avoiding the motor's temperature from being too high when working in harsh environments, and helping to extend the service life of the motor.

[0027] 2. The driving assembly drives the inner ring to rotate, and the inner ring can drive the support rod to rotate, and the support rod drives the cleaning member to rotate, thereby cleaning the inner wall of the cooling pipe, making it difficult for impurities to deposit on the inner wall of the cooling pipe, which helps to ensure the heat exchange efficiency of the cooling pipe.

[0028] 3. After the fan is started, the wind can drive the gear ring to rotate, the gear ring drives the gear to rotate, and the support rod can be driven to rotate with the cooperation of the outer ring and the inner ring, so as to clean the inner wall of the cooling pipe; the rotation of the support rod does not require the setting of other power sources, so it is more energy-saving.

[0031] The following is combined with Figure 1-6 This application is described in further detail.

[0032] The present application embodiment discloses a vertical pipeline pump for conveying high-solid content, high-viscosity non-Newtonian fluid.

An inlet 11 is provided at one end of the pump body 1, and an outlet 12 is provided at the end of the pump body 1 away from the inlet 11, and the inlet 11 and the outlet 12 are located on the same straight line; a cavity connected to the inlet 11 and the outlet 12 is provided inside the pump body 1, and the impeller is rotatably arranged in the cavity, and the rotation axis of the impeller is perpendicular to the axis of the inlet 11. The motor bracket 2 is fixedly connected to the pump body 1 by bolts, and the motor 21 is fixedly connected to the motor bracket 2 by bolts, and the output shaft of the motor 21 is coaxially fixedly connected to the impeller; in this embodiment, the axis of the output shaft of the motor 21 is vertically arranged as an example for explanation. After the motor 21 is started, the impeller can be driven to rotate, and when the impeller rotates, the fluid can be sucked into the pump body 1 from the inlet 11, and then the fluid is swung to the outside of the impeller under the action of the impeller, and then discharged from the outlet 12, thereby achieving the effect of supercharging.

The liquid storage ring 31, the upper connecting ring 33 and the lower connecting ring 32 are all annular tubular structures, and are provided with cavities for the flow of coolant. In this embodiment, the coolant is cooling water. The water pump, the liquid storage ring 31 and the lower connecting ring 32 are all fixedly connected to the motor bracket 2; the lower connecting ring 32 is coaxially arranged on the outside of the motor 21, and the liquid storage ring 31 is coaxially arranged on the outside of the lower connecting ring 32; the input end of the water pump is connected to the cavity inside the liquid storage ring 31, and the output end of the water pump is connected to the cavity inside the lower connecting ring 32.

[0034] The cooling tube 34 is vertically arranged, and a plurality of cooling tubes 34 are arranged in a circular array, and the cooling tube 34 is arranged in a ring on the outside of the motor 21; the bottom end of the cooling tube 34 is fixedly connected to the lower connecting ring 32. The upper connecting ring 33 and the lower connecting ring 32 are coaxially arranged, and the upper connecting ring 33 is fixedly connected to the top of the cooling tube 34. The two ends of the cooling tube 34 are respectively connected to the cavities inside the upper connecting ring 33 and the lower connecting ring 32. Therefore, the coolant flowing in the cooling tube 34 can take away the heat of the motor 21, which helps to accelerate the heat dissipation of the motor 21. Furthermore, a thermal pad 4 is fixedly connected to the outer wall of the cooling tube 34, and the side of the thermal pad 4 away from the cooling tube 34 is against the outer wall of the motor 21, so that the thermal pad 4 can increase the contact area between the cooling tube 34 and the motor 21, thereby enhancing the heat dissipation effect.

[0035] The radiator 35 includes a heat pipe 351 and a heat sink 352. The motor bracket 2 is fixedly connected to a support 8, and a plurality of heat sinks 352 are arranged in parallel and spaced apart, and the heat sink 352 is fixedly connected to the support 8. The two ends of the heat pipe 351 are respectively connected to the upper connecting ring 33 and the liquid storage ring 31, so that the coolant can circulate; a part of the heat pipe 351 is located between the heat sink 352, so that the coolant after heat exchange with the motor 21 can flow into the heat pipe 351, and then the coolant in the heat pipe 351 can fully contact with the heat sink 352, so as to achieve rapid cooling of the coolant. The fan 36 is fixedly connected to the support 8, and the air outlet of the fan 36 faces the heat sink 352, so the setting of the fan 36 can accelerate the air flow at the heat sink 352, thereby accelerating the heat dissipation of the heat sink 352.

[0036] Reference Figure 3 A cleaning assembly 5 is also provided in the cooling tube 34, and the cleaning assembly 5 includes a support rod 51, a cleaning member and an inner ring 54. The support rod 51 is coaxially arranged inside the cooling tube 34; the inner walls at both ends of the cooling tube 34 are fixedly connected with a connecting seat 9, the support rod 51 is arranged between the two connecting seats 9, and the end of the support rod 51 is rotatably connected to the connecting seat 9. The cleaning member is a bristle 52, which is fixedly connected to the support rod 51 and arranged along the radial direction of the cooling tube 34; the bristles 52 are arranged in two rows, and each row of bristles 52 is arranged along the length direction of the support rod 51; the side of the bristles 52 away from the support rod 51 abuts against the inner wall of the cooling tube 34. Therefore, when the support rod 51 rotates, the bristles 52 can be driven to rotate, thereby cleaning the inner wall of the cooling tube 34, so that impurities such as scale are not easily accumulated on the inner wall of the cooling tube 34, and the heat exchange effect can be ensured. The inner ring 54 is a circular ring, and the inner ring 54 is coaxially fixedly connected to the bottom end of the support rod 51. The outer diameter of the inner ring 54 is smaller than the inner wall diameter of the cooling tube 34, so the outer wall of the inner ring 54 and the inner wall of the cooling tube 34 are spaced apart, so that the resistance encountered by the inner ring 54 when rotating is small.

[0037] Reference Figure 3 , Figure 4 and Figure 5 , a driving assembly 6 for driving the inner ring 54 to rotate is arranged on the outside of the cooling tube 34, and the driving assembly 6 includes an outer ring 61, a gear ring 62, a gear 63, a first magnetic member 64 and a second magnetic member 65. The outer ring 61 is a circular ring, and a plurality of outer rings 61 are arranged; the number of outer rings 61 is the same as the number of inner rings 54, and each outer ring 61 corresponds to an inner ring 54. The inner diameter of the outer ring 61 is the same as the outer wall diameter of the cooling tube 34, and the outer ring 61 is sleeved on the outer wall of the bottom end of the cooling tube 34, so that the outer ring 61 and the cooling tube 34 are rotatably connected. The outer ring 61 and the corresponding inner ring 54 are located at the same height of the cooling tube 34.

[0038] The inner ring 54 is provided with a first mounting groove, and the first magnetic member 64 is fixedly connected to the first mounting groove; the outer ring 61 is provided with a second mounting groove, and the second magnetic member 65 is fixedly connected to the second mounting groove; the first magnetic member 64 and the second magnetic member 65 are both magnets, and the magnetic pole directions of the outer side of the first magnetic member 64 and the inner side of the second magnetic member 65 are opposite. Therefore, when the inner ring 54 rotates, so that the first magnetic member 64 is located on the side close to the second magnetic member 65, the first magnetic member 64 and the second magnetic member 65 tend to attract each other. At this time, the second magnetic member 65 rotates, which can make the first magnetic member 64 rotate with it, that is, the rotation of the outer ring 61 can drive the inner ring 54 to rotate in the same direction.

[0039] The gear ring 62 is an inner gear ring, which is coaxially sleeved on the outer side of the motor 21 and rotatably arranged on the motor bracket 2. A plurality of gears 63 are provided, and the number of gears 63 is the same as the number of outer rings 61. Each gear 63 corresponds to an outer ring 61, and the gear 63 is coaxially fixedly connected to the outer wall of the outer ring 61. The gear 63 is meshed with the inner side of the gear ring 62, so that when the gear ring 62 rotates, the gear 63 can be driven to rotate, and the gear 63 drives the outer ring 61 to rotate. Under the tendency of the first magnetic member 64 and the second magnetic member 65 to attract each other, when the outer ring 61 rotates, the inner ring 54 is driven to rotate, and the inner ring 54 drives the support rod 51 to rotate, so that the inner wall of the cooling pipe 34 is cleaned by the bristles 52 on the support rod 51.

[0040] Reference Figure 2 , a guide frame 7 is fixedly connected to the support 8 on the side of the heat sink 352 away from the fan 36, and both ends of the guide frame 7 are provided with openings; one end of the guide frame 7 faces the heat sink 352, and the other end of the guide frame 7 is fixedly connected to a guide ring 71. The guide ring 71 is an annular tubular structure with a notch, and a cavity for air flow is provided inside the guide ring 71, and the cavity inside the guide ring 71 is connected to the guide frame 7. The guide ring 71 is coaxially arranged above the gear ring 62. A guide pipe 711 is fixedly connected to the inner wall of the guide ring 71, and one end of the guide pipe 711 is connected to the cavity inside the guide ring 71, and the other end of the guide pipe 711 faces the outside of the gear ring 62. A wind shield 621 is fixedly connected to the outer wall of the gear ring 62, and a plurality of wind shields 621 are provided and arranged in a circular array; the wind shield 621 is a hemispherical shell structure. One end of the guide tube 711 faces the wind shield 621, so after the fan 36 is started, it can not only blow air to the heat sink 352 to accelerate the heat dissipation of the heat sink 352; the wind flowing through the heat sink 352 can flow into the guide frame 7 and the guide ring 71 in turn, and then be discharged from the end of the guide tube 711. The discharged wind can push the wind shield 621 to rotate, so that the gear ring 62 rotates. When the gear ring 62 rotates, it can drive the gear 63 to rotate. With the cooperation of the outer ring 61 and the inner ring 54, it can drive the support rod 51 to rotate, thereby achieving the cleaning of the inner wall of the cooling tube 34.

[0041] The implementation principle of Example 1 is as follows: after the motor 21 is started, it can drive the impeller to rotate. Under the action of the impeller, the fluid can be sucked in from the inlet 11 of the pump body 1, and then the fluid is thrown out from the center of the impeller to the outside under the action of centrifugal force, and then discharged from the outlet 12 of the pump body 1, thereby achieving the pressurization effect of the pipeline pump.

[0042] The motor 21 generates heat during operation. At the same time, the water pump can pump the coolant in the liquid storage ring 31 into the lower connecting ring 32. The coolant in the lower connecting ring 32 flows upward along the cooling pipe 34. The coolant flowing in the cooling pipe 34 can exchange heat with the housing of the motor 21 and take away part of the heat generated by the motor 21. Then the coolant after heat exchange flows into the upper connecting ring 33 and then flows into the heat dissipation pipe 351. The coolant in the heat dissipation pipe 351 will fully exchange heat with the heat sink 352, and then use the heat sink 352 to quickly dissipate the heat into the air, thereby cooling the coolant. Then the cooled coolant flows into the liquid storage ring 31 again, realizing the recycling of the coolant. During operation, the fan 36 is in the on state, and the fan 36 can blow air to the heat sink 352, thereby accelerating the air flow at the heat sink 352 and accelerating the heat exchange between the heat sink 352 and the air.

[0043] The wind flowing through the heat sink 352 flows into the guide ring 71 through the guide frame 7, and then the wind in the guide ring 71 can be discharged outward through the guide pipe 711. The discharged wind can drive the wind shield 621 to rotate, so that the gear ring 62 rotates. When the gear ring 62 rotates, it can drive the gear 63 to rotate, and the gear 63 drives the corresponding outer ring 61 to rotate; under the action of the tendency of the first magnetic member 64 and the second magnetic member 65 to attract each other, when the outer ring 61 rotates, it can drive the inner ring 54 to rotate, and the inner ring 54 drives the support rod 51 to rotate, so that the inner wall of the cooling pipe 34 is cleaned by the bristles 52 on the support rod 51, which can reduce the impurities such as scale accumulated on the inner wall of the cooling pipe 34, which helps to ensure the heat exchange efficiency of the cooling pipe 34, thereby enhancing the heat dissipation effect of the motor 21 and helping to extend the service life of the pipeline pump.

[0044] Example 2 Reference Figure 6, the difference between this embodiment and embodiment 1 is that the cleaning member in this embodiment is a scraper 53, and the scraper 53 is fixedly connected to the support rod 51. There are multiple scrapers 53 and they are staggered along the length direction of the support rod 51, and each scraper 53 is inclined; the side of the scraper 53 away from the support rod 51 is sharp and abuts against the inner wall of the cooling tube 34. Therefore, when the support rod 51 rotates, the scraper 53 can be driven to rotate, so as to scrape off the impurities such as scale adhering to the inner wall of the cooling tube 34, and the heat exchange efficiency can be ensured. Since the multiple scrapers 53 are staggered, the impact on the flow of the coolant in the cooling tube 34 can be reduced. Since the scrapers 53 are inclined, the multiple scrapers 53 can form a spiral structure together. When the support rod 51 drives the scrapers 53 to rotate, the scrapers 53 will have a tendency to push the coolant upward, which helps to accelerate the flow of the coolant, thereby enhancing the heat dissipation effect.

[0045] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
