Description

Technical Field

[0001] This utility model relates to the field of magnetic pump technology, and in particular to a strong self-priming magnetic pump with cooling function. Background Technology

[0002] The development of magnetic pumps has always revolved around the iterative development of industry needs. Scenario-driven technological improvements have solved the industry pain point of conveying toxic solvents and highly hazardous media. The leak-free characteristics of magnetic pumps have become a necessity. In the upgrading of industrial automation, the optimization of magnetic pumps in motors and control systems has achieved high-efficiency upgrades. Through magnetic drive technology, contactless power transmission is achieved. Relying on material advancements and market demands, it has gradually developed into a key piece of equipment for conveying highly hazardous and corrosive liquids. With increasingly stringent global environmental regulations and the growing demand from enterprises for zero-pollution conveying equipment, magnetic pumps, due to their leak-free and easy-to-clean characteristics, have become leading equipment in the field of environmental protection.

[0003] Magnetic drive pumps replace dynamic seals with static seals, completely solving the problems of running, leaking, dripping, and seeping that are unavoidable with mechanical seals. The pump body and flow parts are made of corrosion-resistant materials and are widely used in the petroleum, chemical, and pharmaceutical industries for pumping liquids. However, with the development of industrial production, higher requirements have been placed on the self-priming ability and cooling performance of magnetic drive pumps. In current operating scenarios, magnetic drive pumps have relatively weak self-priming ability and long single self-priming time. In environments with high fluid viscosity, they are prone to failing to draw liquid. At the same time, key components overheat during long working hours, which can easily lead to failure risks. They cannot improve operating efficiency during operation, resulting in high maintenance costs, low working efficiency, and reduced service life for magnetic drive pumps. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 and attached Figure 2 This utility model provides an embodiment of a strong self-priming magnetic pump with cooling function, comprising a hollow housing 1, a self-priming shell 14 fixedly connected to the left side of the hollow housing 1, a water inlet pipe 16 fixedly connected to the outer wall of the self-priming shell 14, a suction pipe 3 fixedly connected to the right side of the water inlet pipe 16, a sealing ring 4 fixedly connected to one end of the suction pipe 3, a clamp 5 fixedly connected to the outer wall of one end of the suction pipe 3, a fixing nut 6 provided on the outer wall of the clamp 5, and a self-priming chamber 12 fixedly connected to the inner wall of the clamp 5. The inner wall of the self-priming chamber 12 is rotatably connected to a rotating shaft 7, the outer wall of the rotating shaft 7 is fixedly connected to a spiral blade 8, the middle of the rotating shaft 7 is fixedly connected to an impeller 9, the top of the self-priming chamber 12 is fixedly connected to a drain pipe 11, the left side of the outer wall of the drain pipe 11 is connected to a circulation ring 10, the right side of the self-priming chamber 12 is fixedly connected to a sealing cover 13, the right side of the sealing cover 13 is fixedly connected to a return valve 15, the outer wall of the return valve 15 is provided with a cooling mechanism 2, the cooling mechanism 2 is used for cooling and heat dissipation;

[0032] Specifically, the hollow shell 1 serves as the basic load-bearing component of the entire magnetic pump. The suction pipe 3 is the liquid intake channel of the pump body, with one end fixedly connected to the inlet pipe 16 and the other end connected to the self-priming chamber 12 via a sealing ring 4 and a clamp 5. The sealing ring 4 is installed at the connection between the suction pipe 3 and the self-priming chamber 12, and the clamp 5 is fitted onto the outer wall of the connection between the suction pipe 3 and the self-priming chamber 12, serving as a fastening component connecting the two. The fixing nut 6 is located on the outer wall of the clamp 5, serving as a fastening adjustment part for the clamp 5. The rotating shaft 7 is installed on the inner wall of the self-priming chamber 12 and is the core component for transmitting power. The spiral blade 8 enhances the self-priming capability of the pump body, shortens the self-priming time, and ensures that the pump body quickly enters the normal conveying state. The impeller 9 is the key component for realizing liquid pressurization and conveying, delivering high-pressure liquid to the discharge pipe 1. 1. The process of pressurizing and transporting the liquid is completed. The circulation ring 10 diverts some of the high-pressure liquid in the drain pipe 11 and returns it to the self-priming chamber 12. The drain pipe 11 discharges the high-pressure liquid after being pressurized by the impeller 9 from the self-priming chamber 12 and transports it to the subsequent pipeline or equipment to complete the liquid transport task. The sealing cover 13 seals the right opening of the self-priming chamber 12. The installation of the inlet pipe 16 of the self-priming shell 14 provides support, making the connection between the inlet pipe 16 and the self-priming chamber 12 more stable. The return valve 15 assists in cooling the surrounding components and works with the cooling mechanism 2 to improve the heat dissipation effect. The inlet pipe 16 guides the liquid to be transported into the suction pipe 3 and then into the self-priming chamber 12. The cooling mechanism 2 is the core component for realizing the cooling and heat dissipation function of the pump body. Its main function is to cool down the return valve 15 and the surrounding heat-generating components.

[0033] Please see the appendix Figure 3 and attached Figure 5 The cooling mechanism 2 includes a heat sink 204, one end of which is threaded to the inner wall of the hollow shell 1. A condenser pipe 201 is fixedly connected to the outer wall of the return valve 15. A heat sink 202 is installed on the right side of the outer wall of the rotating shaft 7. A fan blade 203 is fixedly connected to the right end of the rotating shaft 7. A spiral port 205 is fixedly connected to one end of the heat sink 204. A filter screen 206 is fixedly connected to the inner wall of the heat sink 204. An air inlet 208 is opened at the lower front side of the hollow shell 1, and an air outlet 207 is opened at the lower rear side of the hollow shell 1.

[0034] Specifically, the heat sink 204 serves as a protective component of the cooling mechanism 2. One end is securely connected to the inner wall of the hollow shell 1 via a threaded connection, facilitating disassembly and assembly during later maintenance. The return valve 15, a key control component within the equipment, has a condenser tube 201 fixedly connected to its outer wall. The condenser tube 201, through a tight-fitting installation, can quickly absorb the heat generated by the return valve 15 during operation. A heat sink 202 is specially installed on the right side of the outer wall. By increasing the heat-receiving area, the heat sink 202 allows the fan blades 203 to rotate synchronously when the rotating shaft 7 is running, generating continuous airflow power, accelerating the air circulation speed inside the equipment, and improving the overall heat dissipation efficiency. To prevent external dust and impurities from entering the equipment, a filter screen 206 is fixedly connected to the inner wall of the heat dissipation cover 204. The filter screen 206 can effectively filter the incoming air to ensure the cleanliness of the internal environment. To form a complete air circulation path, an air inlet 208 is opened at the lower front side of the hollow shell 1. Outside cold air enters the equipment through the air inlet 208, flows through each heat-generating component under the action of the fan blades 203, absorbs heat and becomes hot air, and is finally discharged from the air outlet 207 opened at the lower rear side of the hollow shell 1. Through such circulation, the cooling mechanism 2 can continuously remove the heat inside the equipment to ensure that each component is always within a suitable operating temperature range.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 The outer wall of the self-priming shell 14 is fixedly connected to a water inlet pipe 16, the top of the self-priming shell 14 is fixedly connected to a water outlet pipe 17, the bottom of the hollow shell 1 is fixedly connected to a base 18, and the bottom of the heat dissipation cover 204 is fixedly connected to a fixing bracket 19.

[0036] Specifically, the self-priming shell 14, as a component of the fluid transport system, has an inlet pipe 16 securely connected to its outer wall, introducing external fluid into the self-priming shell 14. At the same time, an outlet pipe 17 is also fixedly connected to the top of the self-priming shell 14. The inlet pipe 16 and the outlet pipe 17 form a complete fluid transport path. The bottom of the hollow shell 1 is securely connected to the base 18, which serves as the basic support component of the entire device, preventing the device from shifting or tipping over due to vibration. The bottom of the heat sink 204 is fixedly connected to a fixing bracket 19, which is specifically designed to assist in fixing the heat sink 204, thereby ensuring that the coordinated operation of each component of the cooling mechanism 2 is not affected, and enabling the orderly circulation and transport of fluid in the entire system.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4The outer wall of the self-priming shell 14 is fixedly connected with an exhaust screw plug 20, the outer wall of the hollow shell 1 is fixedly connected with a hanging ring 21, the top of the hollow shell 1 is provided with a lifting column 22, and the middle part of the base 18 is provided with a support groove 23.

[0038] Specifically, a small exhaust plug 20 is fixedly connected to the outer wall of the self-priming shell 14. When gas accumulates inside the self-priming shell 14 due to fluid flow, the gas can be discharged in time by loosening the small exhaust plug 20. A hanging ring 21 is fixedly connected to the outer wall of the hollow shell 1, making the management and operation of the equipment more convenient. A lifting column 22 is provided on the top of the hollow shell 1, providing a support point. When the equipment is easy to move, the lifting column 22 can be connected by hooks and other components to lift the hollow shell 1 and the entire set of internal components stably. A support groove 23 is provided in the middle of the base 18. As the core load-bearing and positioning structure of the base 18, the support groove 23 is mainly used to support the internal components of the equipment. By distributing the weight of the components through the support groove 23, the deformation of the base 18 or the components themselves is avoided due to excessive local stress.

[0039] Please see the appendix Figure 1 and attached Figure 3 A motor 25 is fixedly connected to the inner wall of the hollow shell 1. The output end of the motor 25 is fixedly connected to one end of the rotating shaft 7. A pump shaft 28 is fixedly connected to the outer wall of the rotating shaft 7. A fixing frame 26 is fixedly connected to the bottom of the motor 25. A controller 24 is fixedly connected to one end of the base 18. An electrical box 27 is fixedly installed on the top of the motor 25.

[0040] Specifically, a motor 25 is fixedly connected to the inner wall of the hollow shell 1. As the core power source of the equipment, the output end of the motor 25 is fixedly connected to one end of the rotating shaft 7. When the motor 25 starts running, it can directly drive the rotating shaft 7 to rotate synchronously, providing continuous and stable power support for the core operation of the equipment. A pump shaft 28 is also fixedly connected to the outer wall of the rotating shaft 7. As a component related to fluid processing, the pump shaft 28 ensures operational efficiency. At the same time, a second fixing frame 26 is fixedly connected to the bottom of the motor 25. The top surface of the second fixing frame 26 is fixedly connected to the bottom of the motor 25 to ensure the overall reliable operation of the equipment. A controller 24 is fixedly connected to one end of the base 18. The controller 24 can be preset with a program or operated manually to achieve precise control of the operating status of the motor 25. From the perspective of the supporting structure of the motor 25, an electrical box 27 is fixedly installed on its top. The electrical box 27 integrates the wires required for the operation of the motor 25. On the one hand, it can protect these electrical components, and on the other hand, it can neatly store the messy wires.

[0041] Working principle: When the magnetic pump is working, the liquid enters through the inlet pipe 16, passes through the suction pipe 3 to the self-priming chamber 12. The liquid flows between the suction pipe 3 and the self-priming chamber 12, and a sealing ring 4 seals the liquid to prevent it from flowing out. The fixing nut 6 on the outer wall of the clamp 5 can fix the suction pipe 3 and the self-priming chamber 12 and can also be disassembled for easy replacement. The rotating shaft 7 inside the self-priming chamber 12 rotates, driving the spiral blade 8 to rotate faster, so that the liquid quickly enters the self-priming chamber 12. Then the rotation of the impeller 9 carries the liquid into the discharge pipe 11. The discharge pipe 11 discharges the liquid through the outlet pipe 17. The middle of the discharge pipe 11 is connected to the circulation ring 10 to ensure self-priming performance and stable operation, and also to assist in exhaust. One end of the self-priming chamber 12 is fixedly connected to a sealing cover 13 to seal the self-priming chamber 12. The return valve 15 on the right side of the sealing cover 13 prevents the liquid from flowing back, enhances the self-priming ability, maintains the liquid volume in the pump, improves working efficiency, prevents dry friction, and extends service life.

[0042] A condenser pipe 201 is fixedly connected to the outer wall of the return valve 15. A fan blade 203 is rotatably connected to the rotating shaft 7 at the output end of the motor 25. A heat sink 202 installed on the left side of the fan blade 203 will cool the pump shaft 28 when the motor 25 rotates. A heat sink 204 is located on the right side of the inner wall of the hollow housing 1. One end of the heat sink 204 has a spiral opening 205, which allows the heat sink 204 to be rotated to the hollow housing 1 and disassembled. A filter screen 206 is installed inside the heat sink 204 to filter the air. There are air inlets 208 and air outlets 207 on the front and rear sides of the hollow housing 1, respectively. When air enters from the air inlet 208, it is cooled by the rotation of the fan blade 203 and the heat sink 202, and then discharged from the air outlet 207, so that the air is circulated. This suppresses overheating of key components, avoids performance degradation and failure risks, and directly improves the safety of use and the life of the equipment.
