Description

Technical Field

[0001] This invention relates to the field of water pump cooling technology, and in particular to a self-circulating water pump cooling device. Background Technology

[0002] In many fields such as industrial production, agricultural irrigation, and municipal water supply, water pumps are the core equipment for fluid transportation, and their operational stability directly affects the normal operation of the entire system. During the operation of a water pump, the sealing structure between the drive shaft and the pump body is a key component to prevent fluid leakage. Currently, mechanical seals (composed of components such as a rotating ring, a stationary ring, and springs) are the mainstream choice to replace traditional packing seals to improve sealing reliability and reduce friction loss. However, the rotating ring of the mechanical seal rotates at high speed with the drive shaft and comes into close contact with the fixed stationary ring, inevitably generating a large amount of frictional heat. At the same time, the fluid transported by the pump body (especially high-temperature and corrosive media) will further conduct heat to the sealing surface. The superposition of these two heat sources can easily lead to a sharp increase in the temperature of the sealing surface, causing a series of problems: thermal deformation of the sealing surface creating gaps, decreased material hardness accelerating wear, and aging and cracking of auxiliary seals, ultimately leading to seal failure, fluid leakage, and in severe cases, pump shutdown or even safety accidents. Therefore, equipping the mechanical seal with an efficient cooling device is a necessary condition for ensuring the long-term stable operation of the water pump.

[0003] Chinese Patent Publication No. CN113266606A discloses a fully self-circulating water pump mechanical seal cooling device, including a water pump rotating shaft and an impeller. The impeller is located at the front end of the water pump rotating shaft, and a cooling fan is provided at the rear end of the water pump rotating shaft. A mechanical seal cooling device is also provided on the water pump rotating shaft. The water pump rotating shaft passes through the mechanical seal cooling device and is connected to the impeller. This invention relates to the field of sealing and cooling device technology. This fully self-circulating water pump mechanical seal cooling device enables the water pump to achieve long-term dry running without damage, making it more resistant to dry running and greatly improving the service life of the water pump. The overall structure is simple and highly practical.

[0004] However, the above-mentioned patent documents still have the following defects in practice; Although the aforementioned patent document device features circulating cooling, it lacks a coolant filtration mechanism, which fails to remove metal debris generated by mechanical seal wear, rust and impurities in the pipes, and other contaminants. This can easily lead to blockage of the cooling channels and affect cooling stability. Summary of the Invention

[0005] The main objective of this invention is to provide a self-circulating water pump cooling device that can effectively solve the problems caused by metal debris generated by mechanical seal wear and pipeline corrosion.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A self-circulating water pump cooling device includes a base for installation. A motor is mounted on one side of the upper part of the base, and a drive shaft is connected to the output end of the motor. A pump body for pumping water is also mounted on the other side of the base. A cooling component is arranged in the middle of the pump body near the motor.

Both the rear wall and the front wall of the inner cavity of the rear cover are provided with protective rings for protection. Several springs are also arranged in a ring on the rear wall and the front wall of the inner cavity of the rear cover. The ends of the springs located on the left and the springs located on the right that are close to each other are fixedly installed with copper ring tubes. The ends of the two copper ring tubes that are close to each other are fixedly installed with stationary rings. A circulation assembly is also installed on one side of the outer surface of the two copper ring tubes. A partition plate is provided on one side of the inner cavity of the two copper ring tubes.

[0008] Preferably, the moving ring is fixedly connected to one side of the transmission shaft surface, and the ends of the two stationary rings that are close to each other are respectively attached to the two sides of the moving ring.

[0009] Preferably, the circulation assembly includes two delivery pipes respectively disposed on one side of the surface of two copper ring pipes. The ends of the two delivery pipes on the upper side and the two delivery pipes on the lower side away from the copper ring pipes are each equipped with a balloon. The two balloons on the upper side are each provided with a recovery pipe connected to them, and the two balloons on the lower side are each provided with a liquid inlet pipe connected to them. The outer surfaces of the liquid inlet pipe and the recovery pipe are connected by two connecting blocks.

[0010] Preferably, both connecting blocks are connected to one side of the inner surface of the protective cover, and the two conveying pipes on the same side are connected to the inner cavity of the copper ring pipe on the same side and are respectively located at the upper and lower parts of the partition plate on the same side.

[0011] Preferably, the filtration mechanism includes a fixed cylinder disposed in the water outlet cavity of the pump body. An impeller is rotatably disposed inside the fixed cylinder. A transmission rod is connected to the middle of the impeller cavity. Two meshing bevel gears are disposed at the end of the transmission rod away from the impeller. A transmission rod is disposed in the middle of the bevel gears in the horizontal part. A support sleeve for support is sleeved on the outer surface of the transmission rod. A worm gear is also connected to the top of the transmission rod. The input end of the worm gear is fixedly installed at the bottom of the liquid storage tank and communicates with its inner cavity. A heat dissipation component for cooling is also installed on the horizontal part of the recovery pipe.

[0012] Preferably, a filter assembly for filtration is also provided on the upper side of the outer surface of the transmission rod, and the output end of the worm gear is connected to the end of the inlet pipe away from the balloon.

[0013] Preferably, the filter assembly includes a filter cartridge disposed in and connected to the vertical part of the inlet pipe. A filter plate is installed in the middle of the inner cavity of the filter cartridge. A fixing ring is fixedly connected to the upper part of the outer surface of the filter cartridge. Connecting plates are arranged in a ring at the bottom of the fixing ring. A retaining ring is also connected to the bottom of several connecting plates. A storage ring for receiving impurities is connected to the inner surface of the retaining ring by a thread. A number of springs are arranged in a ring on the side of the bottom of the fixing ring near the axis of the filter cartridge. A sealing sleeve for sealing is provided at the bottom of several springs. An annular groove for material discharge is opened in the middle of the filter cartridge. A pulley assembly is rotatably installed on the top of the filter cartridge. The other side of the pulley assembly is connected to the upper part of the outer surface of the transmission rod. An arc-shaped scraper is fixedly connected to the lower end of the pulley assembly located at the top of the filter cartridge by a connecting rod. The arc-shaped scraper is in contact with the surface of the filter plate.

[0014] Preferably, the heat dissipation assembly includes fins disposed on the outer surface of the horizontal portion of the recovery pipe, a fan is also disposed at the rear of the fins, and a second pulley assembly is connected to the fan shaft, with the other side of the second pulley assembly connected to one side of the outer surface of the drive shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the kinetic energy of the fluid flowing through the pump body's outlet chamber impacts the impeller inside the fixed cylinder to rotate. Through a transmission structure such as bevel gears and transmission rods, the impeller drives the worm gear to extract coolant from the storage tank. The entire process does not require an external motor, cooling pump, or other independent power source, which not only reduces equipment energy consumption but also simplifies the system structure and reduces maintenance costs caused by power component failures.

[0016] In this invention, the cooling assembly adopts a symmetrical structure of a dynamic ring and two stationary rings on both sides. With the clamping force of the spring, efficient sealing is achieved. At the same time, the copper ring tube is tightly fitted to the stationary ring, and the coolant flows directly inside the copper ring tube to carry away the frictional heat of the dynamic and stationary rings. This achieves the simultaneous completion of sealing barrier construction and precise cooling, effectively avoiding deformation and wear of the sealing surface and aging of auxiliary sealing components caused by high temperature, and significantly extending the service life of the mechanical seal.

[0017] In this invention, the filter assembly integrates a filter plate, a rotating arc-shaped scraper, and a sealing sleeve structure. During the coolant circulation process, it can automatically scrape off impurities on the surface of the filter plate to prevent filter plate blockage. When cleaning the impurity storage ring, the sealing sleeve automatically seals the annular groove of the filter cylinder under the action of the spring, and the impurity cleaning can be completed without stopping the machine. This not only ensures the cleanliness of the coolant and prevents uneven cooling caused by blockage of the cooling channel, but also improves the continuous operation capability of the equipment.

[0018] In this invention, the spherical structure in the circulation component can adapt to the displacement changes of the delivery pipe by its own deformation when the dynamic ring and stationary ring become thinner due to long-term friction and undergo slight displacement. This avoids damage to the pipeline due to bending under stress, ensures the integrity of the coolant circulation path, and improves the stability and service life of the device under long-term operating conditions.

[0019] In this invention, the heat dissipation component adopts a combination structure of fins and fan. The fins are set to fit the recovery pipe to increase the heat dissipation area. The fan is linked to the drive shaft through the pulley assembly. The higher the water pump load and the faster the drive shaft speed, the higher the fan heat dissipation intensity will be. It can quickly dissipate the temperature of the coolant after absorbing heat and ensure that the coolant flowing back to the storage tank is always in a reasonable temperature range, which can meet the heat dissipation requirements of different load conditions.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Before use, the pump body 6 in this case needs to be connected to an inlet pipe and an outlet pipe at its input and output ends, respectively. Before use, a certain amount of coolant needs to be injected into the inner cavity of the liquid storage tank 5, and the cooling component 7 can be internally cooled by the circulation of the coolant.

[0024] Example 1, as Figures 1 to 11 As shown, a self-circulating water pump cooling device includes a base 1 for installation. A motor 2 is installed on one side of the upper part of the base 1, and a drive shaft 3 is connected to the output end of the motor 2. A pump body 6 for pumping water is also installed on the other side of the base 1. A cooling component 7 is arranged in the middle of the side of the pump body 6 near the motor 2. A protective cover 9 is also provided on the outside of the cooling component 7. A filter mechanism 8 for circulation is also provided on one side of the cooling component 7. A support frame 4 is also installed between the pump body 6 and the motor 2. A liquid storage tank 5 for storing coolant is provided on the top of the support frame 4.

[0025] In this case, the entire device is first installed in a suitable location using the base 1. Then, the motor 2 is started to drive the drive shaft 3 to rotate. During the rotation of the drive shaft 3, the internal structure of the pump body 6 is rotated, causing the pump body 6 to pump water through the inlet pipe and then discharge it outward through the outlet pipe. While the drive shaft 3 is driving the internal structure of the pump body 6, the fluids such as water and chemical media inside the pump body 6 are under high pressure and may seep outward along the gap between the drive shaft 3 and the pump body 6. The cooling component 7 can effectively prevent the fluid from seeping outward. With the cooperation of the internal structure of the cooling component 7 and the filter mechanism 8, the internal structure can be kept sealed while maintaining a stable temperature, avoiding high temperature leading to seal failure, extending the service life of the mechanical seal, and ensuring the safe operation of the pump body 6. Then, as the fluid continuously flows outward through the outlet chamber from the pump body 6, the internal structure of the transmission filter mechanism 8 moves. During the movement of the internal structure of the filter mechanism 8, the coolant inside the storage tank 5 is drawn out and flows into the internal structure of the cooling assembly 7. At the same time, before the coolant is drawn out of the storage tank 5 and enters the cooling assembly 7, the coolant is filtered while the internal structure of the filter mechanism 8 is running to prevent metal debris and impurities from entering the cooling assembly 7 and to avoid uneven cooling caused by blockage of the flow channel. During the flow of the coolant, the heat generated inside the cooling assembly 7 due to sealing is carried away. Simultaneously, during the movement of the internal structure of the filter mechanism 8, the transmission shaft 3 is also rotated to cool the coolant that has absorbed heat. After the coolant dissipates heat, it is circulated back into the storage tank 5, thereby achieving the purpose of circulating cooling.

[0026] Specifically, in order to achieve the purpose of sealing and cooling during the pumping of fluid, refer to Figure 3 , Figure 4 and Figure 5 In this scheme, the cooling assembly 7 includes a rear cover 71 located behind the pump body 6. A rotating ring 72 is located in the middle of the inner cavity of the rear cover 71. Protective rings 78 are provided on both the rear and front walls of the inner cavity of the rear cover 71. Several springs 73 are also arranged in a ring on the rear and front walls of the inner cavity of the rear cover 71. Copper ring tubes 74 are fixedly installed at the ends of the springs 73 located on the left and the springs 73 located on the right that are close to each other. Static rings 75 are fixedly installed at the ends of the two copper ring tubes 74 that are close to each other. A circulation assembly 77 is also installed on one side of the outer surface of the two copper ring tubes 74. A partition plate 76 is provided on one side of the inner cavity of the two copper ring tubes 74.

[0027] Furthermore, the moving ring 72 is fixedly connected to one side of the surface of the drive shaft 3, and the ends of the two stationary rings 75 that are close to each other are respectively attached to the two sides of the moving ring 72.

[0028] When the pump body 6 is running, the fluid inside the pump body 6 is under high pressure and will seep out through the gap between the drive shaft 3 and the pump body 6. The mechanical seal, through the rotating ring 72 that rotates with the drive shaft 3, tightly fits the sealing surface with the stationary ring 75 in the inner cavity of the rear cover 71. With the clamping force of the spring 73, a sealing barrier is formed to block the channel for fluid leakage. Then the rotating ring 72 rotates at high speed with the drive shaft 3, and the two stationary rings 75 are fixed in the mechanical seal cavity of the rear cover 71. The sealing surfaces of the two are in close contact at zero distance. This state of high-speed rotation + high-pressure contact will generate severe friction and form a local high temperature zone. At the same time, the fluid transported in the pump body 6, "especially the high-temperature medium", will also conduct heat to the stationary ring 75 and the rotating ring 72. After the superposition of the two heat sources, the temperature of the sealing surface is very likely to exceed the material's tolerance limit. The moving ring 72 in this case is commonly made of silicon carbide, cemented carbide, and alumina ceramic, while the stationary ring 75 is commonly made of impregnated graphite, silicon carbide, or polytetrafluoroethylene.

[0029] Specifically, in order to achieve the purpose of coolant circulation, refer to Figure 4 and Figure 5 In this scheme, the circulation component 77 includes two delivery pipes 771 respectively disposed on one side of the surface of two copper ring pipes 74. The two delivery pipes 771 on the upper side and the two delivery pipes 771 on the lower side are each equipped with a balloon 773 at the end away from the copper ring pipe 74. The two balloons 773 on the upper side are each provided with a recovery pipe 775 connected to them. The two balloons 773 on the lower side are each provided with a liquid inlet pipe 774 connected to them. The outer surfaces of the liquid inlet pipe 774 and the recovery pipe 775 are connected by two connecting blocks 772.

[0030] Furthermore, both connecting blocks 772 are connected to one side of the inner surface of the protective cover 9, and the two conveying pipes 771 on the same side are connected to the inner cavity of the copper ring pipe 74 on the same side and are located at the upper and lower parts of the partition plate 76 on the same side, respectively.

[0031] At this time, during the process of pumping water out of the pump body 6, the internal structure of the filter mechanism 8 is driven to operate simultaneously. During the operation of the filter mechanism 8, the coolant inside is drawn out, filtered, and enters the inner cavity of the inlet pipe 774. Then, the coolant is transported to the inner cavity of the copper ring pipe 74 through the two balloons 773 and the delivery pipe 771 set on the bottom side. The surface of the copper ring pipe 74 is tightly attached to the surface of the two stationary rings 75. During the flow of the coolant in the inner cavity of the copper ring pipe 74, the heat generated by friction on the surface of the stationary rings 75 is carried away. The coolant with heat flows into the recovery pipe 775 through the delivery pipe 771 on the upper side of the separator 76. During the flow, it is cooled by the internal components of the filter mechanism 8. The cooled coolant then flows back into the storage tank 5 for collection, thereby achieving the purpose of circulation.

[0032] The moving ring 72 and the stationary ring 75 may become thinner due to long-term mutual friction, which will cause the delivery pipe 771 connected to their surface to produce a small displacement. The balloon 773 can deform at the same time when the delivery pipe 771 is displaced, thus ensuring that the delivery pipe 771 will not bend under force.

[0033] Specifically, in order to extract the coolant from the inner cavity of the liquid storage tank 5 for circulation cooling and simultaneous filtration and heat dissipation, refer to Figures 6 to 11 In this scheme, the filtration mechanism 8 includes a fixed cylinder 81 disposed in the water outlet cavity of the pump body 6. An impeller 82 is rotatably disposed inside the fixed cylinder 81. A transmission rod 83 is also connected to the middle of the inner cavity of the impeller 82. Two meshing bevel gears 85 are disposed at the end of the transmission rod 83 away from the impeller 82. A transmission rod 87 is disposed in the middle of the bevel gears 85 located in the horizontal part. A support sleeve 86 for support is sleeved on the outer surface of the transmission rod 87. A worm gear 88 is also connected to the top of the transmission rod 87. The input end of the worm gear 88 is fixedly installed at the bottom of the liquid storage tank 5 and connected to its inner cavity. A heat dissipation component 84 for cooling is also installed on the horizontal part of the recovery pipe 775.

[0034] Furthermore, a filter assembly 89 for filtration is provided on the upper side of the outer surface of the transmission rod 87, and the output end of the worm gear 88 is connected to the end of the inlet pipe 774 away from the balloon 773.

[0035] The impeller 82 mentioned above is half-open; In the above, when the pump body 6 rotates to pump water, the water flows out from the outlet chamber of the pump body 6. During the flow of the water, it impacts the impeller 82 inside the fixed cylinder 81 from the bottom semi-circular opening and rotates. During the rotation of the impeller 82, the transmission rod 83 rotates synchronously. The middle part of the transmission rod 83 is supported on one side of the protective cover 9 by a protective sleeve. Then, during the rotation of transmission rod 83, two meshing bevel gears 85 are simultaneously driven to rotate, causing one of the bevel gears 85 to drive transmission rod 87 to rotate. Then, the rotation of transmission rod 87 drives the internal structure of worm gear 88 to rotate, drawing the coolant from the bottom of the reservoir 5 into the inlet pipe 774. Then, when the coolant flows to the filter assembly 89, the internal components of the filter assembly 89 are simultaneously driven to filter it during the rotation of transmission rod 87. The filtered coolant then flows into the inner cavity of copper ring pipe 74 through inlet pipe 774 for circulation cooling.

[0036] The worm gear 88 mentioned above also adopts the same structural principle as the pump body 6, and the fluid is drawn out by the rotation of the impeller inside.

[0037] Specifically, in order to achieve the purpose of filtering the extracted coolant, refer to Figure 9 and Figure 10In this solution, the filter assembly 89 includes a filter cartridge 891 disposed in and connected to the vertical portion of the inlet pipe 774. A filter plate is installed in the middle of the inner cavity of the filter cartridge 891. A fixing ring 892 is fixedly connected to the upper part of the outer surface of the filter cartridge 891. Connecting plates 894 are arranged in a ring at the bottom of the fixing ring 892. Several connecting plates 894 are also connected to the bottom of the bottom of the connecting plates 894. A impurity storage ring 896 for receiving impurities is connected to the inner surface of the retaining ring 895 by a thread. The bottom of the fixing ring 892 is close to the axis of the filter cartridge 891. A number of springs 897 are arranged in a ring on one side. The bottom of the springs 897 is provided with a sealing sleeve 898 for sealing. An annular groove for material discharge is opened in the middle of the filter cylinder 891. A pulley assembly 893 is rotatably installed on the top of the filter cylinder 891. The other side of the pulley assembly 893 is connected to the upper side of the outer surface of the transmission rod 87. An arc-shaped scraper 899 is fixedly connected to the lower end of the pulley assembly 893 at the top of the filter cylinder 891 through a connecting rod. The arc-shaped scraper 899 is attached to the surface of the filter plate.

[0038] In the above process, the coolant flows into the inner cavity of the filter cartridge 891 through the inlet pipe 774. As the coolant is gradually pressurized, it flows downward through the filter plate set in the inner cavity of the filter cartridge 891, filtering out any impurities that may be present in the coolant onto the surface of the filter plate. Simultaneously, as the transmission rod 87 rotates, it drives the pulley 1 and belt 2 of the pulley assembly 893 to rotate. The rotation of one of the pulleys drives the connecting rod set at the bottom to rotate, and then the two connecting rods drive the arc-shaped scraper 899 to rotate on the surface of the filter plate. During the rotation, the impurities on the surface of the filter plate are scraped off and collected in the inner cavity of the impurity storage ring 896. When the pump body 6 stops running and the impurities collected by the impurity storage ring 896 need to be cleaned, the impurity storage ring 896 is rotated downwards through the thread from the inner surface of the retaining ring 895. During the downward rotation of the impurity storage ring 896, the sealing sleeve 898 is pushed to fit against the top of the outer ring of the impurity storage ring 896 under the pressure of the second spring 897 and moves downwards until the sealing sleeve 898 fits against the surface of the annular groove in the middle of the filter cartridge 891, so that the filter cartridge 891 forms a sealed state. This ensures that the coolant that may be contained inside the liquid inlet pipe 774 will not flow out through the annular groove. The impurity storage ring 896, which is dislodged by the thread rotation, can be scraped off by the operator. After scraping, it can be directly rotated back into the inner wall of the retaining ring 895.

[0039] Specifically, in order to cool the coolant after it has absorbed heat, refer to Figure 6 , Figure 8 and Figure 11In this solution, the heat dissipation component 84 includes fins 841 disposed on the outer surface of the horizontal portion of the recovery pipe 775. A fan 842 is also disposed at the rear of the fins 841. The fan 842 shaft is also connected to a second pulley assembly 843. The other side of the second pulley assembly 843 is connected to one side of the outer surface of the drive shaft 3.

[0040] In the above, the coolant that has absorbed heat is circulated into the inner cavity of the storage tank 5 through the recovery pipe 775. The horizontal part of the recovery pipe 775 is provided with the recovery pipe 775. Then, during the rotation of the pulley 2 and belt 2 of the drive shaft 3, the lower fan 842 is driven to rotate simultaneously. The fan 842 rotates and blows air onto the fins 841, thereby cooperating with the fins 841 to quickly dissipate the heat absorbed by the coolant inside the recovery pipe 775.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
