Description

Technical Field

[0001] The present invention relates to the technical field of magnetic pumps, in particular to a magnetic pump protection device. Background Art

[0002] In numerous industrial sectors, including the chemical, pharmaceutical, and food industries, magnetic pumps, with their leak-free and tight sealing properties, have become critical equipment for conveying corrosive, toxic, hazardous, or high-purity liquids. With the expansion of industrial production and the increasing demand for equipment reliability, the importance of magnetic pump protection devices has become increasingly prominent. These devices are designed to prevent impurities from entering the pump, thereby avoiding mechanical wear and blockage caused by these impurities, thereby ensuring stable operation and extending the service life of the magnetic pump.

[0003] Existing magnetic pump protection devices typically utilize a single filtering structure, such as a simple filter placed at the pump's water inlet. This filter physically blocks impurities from the liquid. Some devices also feature a removable filter cartridge to facilitate cleaning of clogged filters. Furthermore, some protection devices incorporate a protective shield on the outside of the pump to prevent damage from collisions with foreign objects. Some devices also incorporate a pressure sensor to monitor internal pump pressure, alerting operators to blockages when pressure is abnormal, allowing for prompt maintenance.

[0004] However, in actual industrial application scenarios, these existing technologies have many shortcomings. For example, in the process of transporting chemical raw materials, the liquid often contains impurities of various shapes and sizes. A single filter screen is easily clogged quickly and cannot effectively clean the impurities stuck in the mesh, resulting in a sharp drop in filtration efficiency and an increase in the pressure at the water inlet of the pump body, affecting the normal operation of the magnetic pump. At the same time, the existing cleaning method usually requires manual disassembly of the filter screen for cleaning, which is cumbersome and not only takes a lot of time, but also causes a decrease in sealing performance due to frequent disassembly, increasing the risk of liquid leakage. In addition, the existing protective structure can only cope with external collisions, and lacks an effective prevention and treatment mechanism for wear and failure caused by internal impurities, making it difficult to meet the needs of industrial production for efficient and stable operation of equipment. Therefore, the present invention provides a magnetic pump protection device to address the shortcomings of the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please see the attached Figure 1 -Attached Figure 8 An embodiment of the present invention provides a magnetic pump protection device, including a base 1, a motor 2 is installed on the top of the base 1, a pump body 3 is installed on the output end of the motor 2, one end of the pump body 3 is fixedly connected to a cleaning mechanism 4, a filtering mechanism 5 is provided on the inner side of the cleaning mechanism 4, a collecting mechanism 6 is provided at the bottom of the cleaning mechanism 4, and one end of the cleaning mechanism 4 is fixedly connected to a connecting pipe 7.

[0029] The cleaning mechanism 4 includes a cleaning pipe 401 and an anti-blocking component. One end of the cleaning pipe 401 is fixedly connected to one end of the pump body 3. Two positioning sleeves 402 are fixedly connected to the inside of the cleaning pipe 401. The inner sides of the two positioning sleeves 402 are rotatably connected to a reciprocating screw 403. One end of the reciprocating screw 403 is fixedly connected to an impeller 404. The impeller 404 is located at the connection between the cleaning pipe 401 and the connecting pipe 7. After the magnetic pump is started, external water flows into the cleaning pipe 401 through the connecting pipe 7. The water impacts the impeller 404, driving it to rotate, and then driving the reciprocating screw 403 to rotate at high speed. The outer side of the reciprocating screw 403 is threadedly connected to a threaded block 407. The bottom of the threaded block 407 is fixedly connected to a brush plate 408. The bottom of the brush plate 408 is in contact with the inner wall of the cleaning pipe 401. Driven by reciprocating screw 403, threaded block 407 performs a stable reciprocating linear motion along guide rod 1 406, driving brush plate 408 to clean the inner wall of cleaning tube 401, sweeping away deposited impurities and causing them to flow towards filter screen 505 under the impact of the water flow. Fixed block 405 is fixedly connected to the top of positioning sleeve 402. Guide rod 1 406 is fixedly connected to the adjacent sides of the two fixed blocks 405. The inner side of threaded block 407 is slidably connected to the outer side of guide rod 1 406.

[0030] The anti-blocking assembly includes two mounting plates 414, with guide rods 415 fixedly connected to adjacent sides of the two mounting plates 414. A movable block 416 is slidably connected to the outer side of the guide rods 415. The top of the movable block 416 is slidably connected to the inner wall of the cleaning tube 401. A spring 419 is sleeved on the outer side of the guide rods 415. One end of the spring 419 is fixedly connected to the outer side of the mounting plate 414, and the other end of the spring 419 is fixedly connected to the outer side of the movable block 416. A cooperative column 418 is fixedly connected to the bottom of the movable block 416, and a striking rod 417 is fixedly connected to the outer side of the movable block 416. A rotating rod 411 is rotatably connected to the inner wall of the cleaning tube 401. One end of the rotating rod 411 is fixedly connected to the driven bevel gear 412. The other end of the reciprocating screw 403 is fixedly connected to the driving bevel gear 410. The driven bevel gear 412 meshes with the driving bevel gear 410. When reciprocating screw 403 rotates, driving bevel gear 410 rotates driven bevel gear 412, driving rotating rod 411 to cause lever 413 to move in a circular motion. Lever 413 periodically shifts coordinating column 418, driving movable block 416 to compress spring 419. Spring 419, after accumulating energy, releases, pushing movable block 416 to quickly reset, causing impact rod 417 to strike filter screen 505, shaking off impurities stuck in the mesh. Lever 413 is fixedly connected to the outside of rotating rod 411, and the outside of lever 413 contacts the outside of coordinating column 418. A slag discharge port 409 is defined at the bottom of cleaning tube 401.

[0031] The filter mechanism 5 includes a filter box 501, which is arranged on the outside of the cleaning tube 401. A water outlet 506 is provided inside the filter box 501, and the water outlet 506 is connected to the interior of the cleaning tube 401. A sliding plate 502 is slidably connected to the interior of the filter box 501, and a filter screen 505 is provided inside the sliding plate 502. A blocking plate 503 is fixedly connected to the top of the sliding plate 502, and a handle 504 is fixedly connected to the top of the blocking plate 503. When water flows through the filter screen 505, impurities are intercepted, and clean water flows into the pump body 3 through the water outlet 506. When maintenance is required, the operator can easily pull out the sliding plate 502 by holding the handle 504 to clean or replace the filter screen 505.

[0032] The collection mechanism 6 includes a collection box 601, which is fixedly connected to the bottom of the cleaning tube 401. Inclined plates 602 are fixedly connected to both sides of the inner wall of the collection box 601. A sealing plate 603 is provided on the outer side of the collection box 601. The top of the collection box 601 is connected to the slag discharge port 409. Impurities falling from the slag discharge port 409 slide down to the bottom of the collection box 601 under the guidance of the inclined plates 602 and are collected centrally. The sealing plate 603 facilitates the removal of impurities from the collection box 601 while ensuring the sealing of the device.

[0033] Specifically, when the magnetic pump is activated, the device is first connected to an external water pipe via connecting pipe 7, establishing a water flow channel. Once the magnetic pump is activated, the external water, thanks to the suction force generated by the pump body 3, quickly and steadily flows through connecting pipe 7 into the cleaning pipe 401 of the cleaning mechanism 4. The moment the water enters the cleaning pipe 401, its powerful impact directly acts on the impeller 404, causing it to begin rotating at a relatively high speed.

[0034] The rotation of impeller 404, connected via a shaft, precisely transmits power to reciprocating screw 403, driving reciprocating screw 403 to rotate synchronously at high speed. Because threaded block 407 is tightly connected to reciprocating screw 403 via threads, and guided by guide rod 1 406, threaded block 407 performs stable reciprocating linear motion along guide rod 1 406 as reciprocating screw 403 rotates. A brush plate 408, fixedly attached below threaded block 407, also reciprocates accordingly, its bottom tightly fitting the inner wall of cleaning tube 401, sweeping away various impurities that have long been deposited on the inner wall of cleaning tube 401. These swept impurities are then flushed toward filter screen 505 by the continued flow of water.

[0035] Filter 505 is mounted within sliding plate 502, which in turn slides into filter cartridge 501. When water carrying impurities flows through, filter 505 intercepts them, effectively trapping them on the surface and allowing only clean water to flow through water port 506 and into pump body 3. This prevents impurities from entering pump body 3, significantly reducing the risk of wear and damage to the magnetic pump's precision components and significantly extending its service life.

[0036] As the reciprocating screw 403 rotates, the driving bevel gear 410, fixed at its end, also rotates. The driving bevel gear 410 is tightly meshed with the driven bevel gear 412, transmitting power to the driven bevel gear 412 through a gear transmission, which in turn drives the rotating rod 411 to rotate. A shift lever 413, fixed to the outside of the rotating rod 411, performs a circular motion as the rotating rod 411 rotates. When the shift lever 413 rotates to a specific position, it contacts and shifts the coordinating column 418. The coordinating column 418 is connected to the movable block 416. Driven by the shift lever 413, the movable block 416 slides along the second guide rod 415 and compresses the spring 419 mounted on the second guide rod 415, compressing the spring 419 and storing its elastic potential energy. When the shift lever 413 loses contact with the coordinating column 418, the spring 419 quickly releases its elastic potential energy, pushing the movable block 416 to quickly return to its original position. During the resetting process of the movable block 416, the impact rod 417 fixed to its outer side will strike the filter 505 with a large impact force. This impact action can generate a strong vibration, which causes impurities stuck in the mesh of the filter 505 to fall off due to the vibration, effectively preventing the mesh of the filter 505 from being blocked, and ensuring that the filter 505 always maintains good filtering performance and water flow.

[0037] As the impurities in the cleaning tube 401 are continuously swept by the brush plate 408 and rushed towards the filter 505, the impurities intercepted by the filter 505 gradually increase. Some impurities will fall from the slag discharge port 409 at the bottom of the cleaning tube 401 under the action of gravity and water flow. The collection box 601 is connected just below the slag discharge port 409. The inclined plates 602 on both sides of the inner wall of the collection box 601 are cleverly designed. After the impurities fall, they will automatically slide along the inclined surface of the inclined plate 602 to the bottom of the collection box 601, realizing the centralized collection of impurities. The sealing plate 603 arranged on the outside of the collection box 601 plays a sealing role when the device is running to prevent impurities from leaking and polluting the environment; when it is necessary to clean the impurities in the collection box 601, just open the sealing plate 603 to easily take out the impurities, which is very convenient to operate.

[0038] After using the filter 505 for a period of time, it needs to be cleaned or replaced to maintain its filtering effectiveness. To do this, the operator simply grasps the handle 504 on the blocking plate 503 at the top of the sliding plate 502 and smoothly pulls the sliding plate 502 out of the filter box 501 along the internal groove of the filter box 501. Once removed, the filter 505 inside the sliding plate 502 can be thoroughly cleaned to remove impurities attached to the surface. If the filter 505 is severely damaged, it can be easily replaced. The entire maintenance process is simple and efficient, requiring no complex tools or tedious steps.

[0039] Working principle: First, the connecting pipe 7 is used to connect the external water pipe. When the magnetic pump is started to work, the external water will enter the interior of the cleaning mechanism 4 through the connecting pipe 7, and then the water flow will pass through the filter 505 to be filtered, and then flow into the pump body 3, so as to prevent impurities in the water from damaging the magnetic pump, and under the impact of the water flow, the impeller 404 will start to rotate, and then drive the reciprocating screw 403 to rotate the threaded block 407 to move, so that the brush plate 408 will move back and forth, sweeping the impurities deposited inside the cleaning pipe 401, and under the action of the water flow, it will be flushed to the filter 505 and blocked, and then fall from the slag discharge port 409 to the top of the inclined plate 602. When the reciprocating screw 403 rotates, the active bevel gear 410 drives the driven bevel gear 412 to rotate, which makes the rotating rod 411 drive the dial rod 413 to rotate, and then drives the cooperative column 418 to move the movable block 416 and squeeze the spring 419. Under the elastic force of the spring 419, the movable block 416 will quickly reset and drive the impact rod 417 to hit the filter 505, which can shake off the impurities stuck on the mesh of the filter 505. Moreover, the handle 504 can be grasped to pull the sliding plate 502 out of the interior of the filter box 501, which is convenient for cleaning and replacing the filter 505.
