Description

Technical Field

[0001] This utility model relates to the technical field of magnetic vortex pumps, and in particular to a magnetic vortex pump with a magnetic particle filtration device. Background Technology

[0002] With the continuous improvement of industrial automation, magnetic vortex pumps are increasingly widely used in various industries such as chemical, pharmaceutical, and food due to their advantages such as leak-free operation and corrosion resistance. However, in actual operation, especially when handling media containing metal debris, magnetic vortex pumps face a significant problem. Because their working principle relies on an internal rotating magnetic field to drive the impeller, the pump has a strong adsorption effect on any ferromagnetic substances present in the liquid passing through the pump body during operation. Over time, these adsorbed metal debris gradually accumulates inside the pump body. When too much metal debris accumulates inside the pump body, it not only interferes with the normal operation of the pump's internal components, such as hindering the free rotation of the impeller, increasing rotational resistance, and causing motor overload; more seriously, it may cause the pump to stop operating completely. This situation will not only lead to production interruption and affect work efficiency, but may also cause equipment damage, increase maintenance costs and time consumption, and pose certain safety hazards.

[0003] Several technologies are currently available that attempt to address this issue, such as using pre-filters or centrifugal separators to reduce the amount of metal debris entering the pump body. However, these methods often fail to fundamentally solve the problem because they cannot effectively collect and promptly remove metal debris during the operation of the magnetic vortex pump. Furthermore, such solutions may increase the system's structural complexity and maintenance difficulty, thereby reducing the overall reliability and stability of operation.

[0004] A search revealed that patent application number CN2024207330035 discloses an electromagnetic metal debris collector, including a base, a collection bucket, a handheld collector, a controller, and a first battery. It is suitable for collecting metal debris inside and outside construction structures, but not for effectively collecting metal debris in flowing media. Patent application number CN2023212056074 discloses a metal debris collection device for sprocket production. Sprockets generate large debris during processing. Debris collection devices typically perform solid-liquid separation of the debris, usually through a filter screen. However, with prolonged use, the filter screen inside the debris collection device is prone to clogging, affecting the debris collection efficiency.

[0005] In summary, the existing drawbacks are:

[0006] (1) During the operation of the magnetic vortex pump, it is necessary to frequently stop the machine and rely on manual cleaning of internal metal debris, which not only affects the continuity of production, but also exposes the lack of automated cleaning mechanism in the current system.

[0007] (2) Physical filtration devices such as pre-filters have limited effectiveness in intercepting metal debris.

[0008] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a magnetic vortex pump with a magnetic particle filtration device, making it more valuable for industrial applications. Utility Model Content

[0020] As a further improvement of this utility model, the inner rotor is interference-fitted with the shaft A of the driving impeller through a clamping ring, and the impeller is connected to the shaft A through a key A.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] The first embodiment of this utility model:

[0037] like Figures 1-3 As shown, a magnetic vortex pump with a magnetic particle filtration device in this embodiment mainly includes a magnetic metal debris collection device 1, a magnetic vortex pump 3, and a three-phase asynchronous motor 24.

[0038] The output end of the three-phase asynchronous motor 24 is connected to the input end of the magnetic transmission mechanism of the magnetic vortex pump 3, and is used to drive the impeller 16 of the magnetic vortex pump 3 to rotate.

[0039] The magnetic drive mechanism of the magnetic vortex pump 3 includes: an outer rotor coupling 21 connected to the output end of a three-phase asynchronous motor 24; a plurality of outer permanent magnets 20 installed inside the outer rotor coupling 21; an inner rotor 17 coaxially arranged with the impeller 16; and a plurality of inner permanent magnets 19 installed on the outside of the inner rotor 17 and magnetically coupled to the aforementioned outer permanent magnets 20.

[0040] The inner rotor 17 is interference-fitted with the shaft A13 of the drive impeller 16 via the clamping ring 18, and the impeller 16 is connected to the shaft A13 via the key A15.

[0041] A limiting sleeve 14 is installed on shaft A13. The limiting sleeve 14 is interference-fitted with shaft A13 and is used to axially position the impeller 16 or the inner rotor 17.

[0042] The external rotor coupling 21 is connected to the shaft B23 on the output end of the three-phase asynchronous motor 24 via key B22.

[0043] After the three-phase asynchronous motor 24 starts, the drive shaft B23 rotates, which drives the outer rotor coupling 21 and its internal outer permanent magnet 20 to rotate together via key B22. The rotating outer permanent magnet 20 drives the inner permanent magnet 19 and the inner rotor 17 to rotate through magnetic coupling. The inner rotor 17 drives the impeller 16 to rotate via key A15, thereby completing the pumping operation.

[0044] A magnetic metal debris collecting device 1 includes a flow pipe 5 and a collector 8. One end of the flow pipe 5 has an inlet flange 4 connected to an external feed pipe, and the other end has an outlet flange 12 connected to the inlet pipe section 2 of a magnetic vortex pump 3. An adsorption pipe for collecting debris is located at the bottom of the flow pipe 5 near the inlet flange 4. An electromagnet 6 is installed outside the adsorption pipe, and the collector 8 is located below the adsorption pipe. The electromagnet 6 is electrically connected to a control unit for controlling its on / off state.

[0045] The adsorption pipe is located at the lowest point of the flow pipe 5, so that the bottom of the flow pipe 5 forms a depression structure for collecting metal debris, and the depression structure is U-shaped.

[0046] A valve 7 is also installed on the pipeline between the electromagnet 6 and the collector 8. The valve 7 is a solenoid valve, which is electrically connected to the control unit. The control unit is configured to open the solenoid valve synchronously when the electromagnet 6 is de-energized.

[0047] The control unit includes a relay 10 and a power supply 11. The switch 9 of the relay 10 is connected in series in the circuit between the power supply 11 and the electromagnet 6. The relay 10 can be a time relay, which can be programmed, for example, every 10 minutes of operation, disconnecting the circuit of the electromagnet 6 and simultaneously opening the solenoid valve, continuing for 30 seconds, then restoring the energized state and closing the solenoid valve.

[0048] The second embodiment of this utility model:

[0049] like Figures 1-3 As shown, the purpose of this embodiment is to construct an automated cleaning mode to achieve efficient and continuous removal of metal debris at the inlet of the magnetic vortex pump.

[0050] This embodiment of a magnetic vortex pump with a magnetic particle filtration device includes a magnetic metal debris collection device 1 and a magnetic vortex pump 3.

[0051] One end of the magnetic metal scrap collection device 1 is connected to the feed pipe via the inlet flange 4, and the other end is connected to the inlet pipe section 2 of the magnetic vortex pump via the outlet flange 12. The magnetic metal scrap collection device 1 includes, in sequence, the inlet flange 4, the flow pipe 5, the electromagnet 6, the valve 7, the collector 8, the switch 9, the relay 10, the power supply 11, and the outlet flange 12.

[0052] The flow passage 5 leads out at its lowest point, and the electromagnet 6 is installed around the outside of the passage. When energized, it is used to attract metal debris flowing through the flow passage 5. The electromagnet 6 is connected to the relay 10. The electromagnet 6 is controlled by switching the power on and off through the switch 9 in the relay 10. The valve 7 is installed below the electromagnet 6, and the collector 8 is installed below the valve 7. When the relay 10 controls the switch 9 to disconnect the power supply 11, the metal debris falls into the collector 8 by gravity because the electromagnet 6 loses its magnetism.

[0053] The magnetic vortex pump comprises, in sequence, shaft A13, limiting sleeve 14, key A15, impeller 16, inner rotor 17, retaining ring 18, inner permanent magnet 19, outer permanent magnet 20, outer rotor coupling 21, key B22, shaft B23, and three-phase asynchronous motor 24. Shaft A13 and limiting sleeve 14 are fixed by interference fit, limiting sleeve 14 is connected to impeller 16 by key A15, and inner rotor 17 and shaft A13 are fixed by interference fit through retaining ring 18.

[0054] The inner permanent magnet 19 is installed circumferentially on the outside of the inner rotor 17, and the outer permanent magnet 20 is installed circumferentially inside the outer rotor coupling 21. The shaft B23 is connected to the outer rotor coupling 21 by key B22. After the three-phase asynchronous motor 24 is powered on, it drives the shaft B23 to rotate. The rotation of the shaft B23 drives the outer rotor coupling 21 and the outer permanent magnet 20 to rotate. The rotation of the outer permanent magnet 20 drives the inner permanent magnet 19 and the inner rotor 17 to rotate. The rotation of the inner rotor 17 drives the shaft A13 to rotate and drives the impeller 16 to rotate.

[0055] This utility model is achieved through the following steps:

[0056] Step 1: When the medium flows into the flow pipeline, the electromagnet on the outside of the flow pipeline is energized, attracting metal debris around the electromagnet. When a certain amount of metal debris is attracted, the relay is de-energized, demagnetizing the electromagnet. When the magnetic force disappears, the metal debris will fall into the collector due to gravity. The relay is periodically energized and de-energized to collect the metal debris. When the collector is full of metal debris, the valve is closed, the collector is removed, the internal metal debris is cleaned, and then it is reinstalled below the valve.

[0057] Step 2: The medium for removing metal debris flows into the inlet of the magnetic vortex pump, passes through the impeller, and flows out through the outlet of the magnetic vortex pump. The working principle of the magnetic vortex pump relies on the internal rotating magnetic field to drive the impeller. The medium for removing metal debris will not accumulate due to the metal debris being attracted by the internal rotating magnetic field, thus affecting the normal operation of the magnetic vortex pump.

[0058] In this embodiment, the magnetic vortex pump integrates an electromagnet on the outside of the flow path. The strong magnetic field generated by the electromagnet attracts ferromagnetic debris from the fluid, thus separating the metal debris. The electromagnet's operating cycle is set by a relay, automating the adsorption and release process and reducing manual intervention. Gravity allows the metal debris, which loses its magnetic attraction after power is cut off, to fall naturally into the collection container below, achieving efficient and stable impurity recovery.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
