Description

Technical Field

[0001] This invention relates to the field of variable frequency water pump technology, specifically to an automated, wear-resistant, and corrosion-resistant variable frequency drainage water pump. Background Technology

[0002] This automated, wear-resistant, and corrosion-resistant variable frequency drainage pump is a high-efficiency drainage device that integrates intelligent automated control, variable frequency speed regulation technology, and high-durability materials. Equipped with an intelligent variable frequency system, it can automatically adjust the speed and operating status according to working conditions, achieving unattended operation, energy saving, and stable drainage.

[0003] Chinese patent CN220706087U discloses an anti-clogging water pump, including a water pump body, an inlet pipe and an outlet pipe on the water pump body, a connecting pipe bolted to the side wall of the inlet pipe, and a self-cleaning anti-clogging mechanism at the end of the connecting pipe away from the inlet pipe. The self-cleaning anti-clogging mechanism includes a self-cleaning filter component and a filter cleaning component. The self-cleaning filter component can filter the water source when it enters the water pump body, filtering out mud, metal residue, stones and other impurities in the water source. At the same time, it can self-clean the filter screen, brushing away the impurities adhering to the filter screen. The filter cleaning component can discharge the filtered impurities and clean the outer wall of the filter screen. While this technical solution can intercept and filter impurities in the water through a filter screen and simultaneously brush away the impurities adhering to the filter screen, it still has significant drawbacks in practical applications. It not only fails to remove impurities embedded in the filter screen mesh but also easily causes mesh blockage and reduced flow capacity. In the existing technology, the water-facing surface cleaning operation can also easily push impurities through the filter screen, weakening the filtration and protection effect. It is also difficult to deal with long, flexible impurities in sewage, which can easily cause filter screen entanglement and jamming of the cleaning mechanism. Furthermore, the separated and filtered impurities will still accumulate around the filter screen, easily causing secondary blockage. Therefore, it cannot meet the filtration and anti-clogging requirements for long-term stable and continuous operation of sewage transportation. Summary of the Invention

[0005] This invention provides an automated, wear-resistant, and corrosion-resistant variable frequency drainage water pump. It has the following beneficial effects: 1. This automated, wear-resistant, and corrosion-resistant variable frequency drainage pump differs from existing technologies that only clear blockages after they occur. It uses continuous reciprocating dredging driven by water flow to ensure the long-term stability of the mesh plate's flow area. It actively clears blockages in the mesh in real time and without interruption, pushing out impurities as soon as they become embedded in the mesh, thus avoiding mesh blockage problems and preventing the phenomenon of decreased flow capacity of the mesh plate or even complete blockage caused by long-term impurity embedding.

[0006] 2. This automated, wear-resistant, and corrosion-resistant variable frequency drainage pump actively grabs and cuts impurities online before they come into contact with the filter screen. It breaks up long, flexible impurities that are prone to clogging into short pieces, avoiding the phenomenon of long impurities covering the filter screen, embedding into the mesh, reducing the flow area, or completely blocking the filter. This significantly improves the continuous flow capacity and anti-clogging stability of the filter. The mechanism is located on the water-facing side of the filter screen, making it easier to collect the cut short impurities and completely preventing long impurities from entangled.

[0007] 3. This automated, wear-resistant, and corrosion-resistant variable frequency water pump directs the impurities intercepted on the water-facing side of the screen away in real time through a periodically opening diversion channel, completely avoiding the blockage problem caused by the continuous accumulation of solid impurities on the screen surface, covering the mesh holes, and embedding them.

[0008] 4. This automated, wear-resistant, and corrosion-resistant variable frequency drainage pump separates impurities from clean water through the filtration structure of the collection tank. The intercepted impurities are concentrated in the collection tank and only need to be cleaned periodically by opening the cover. The filtered clean water is recycled in a closed loop through the return pipe, with no loss of water delivery volume. At the same time, the matching one-way valve and filter screen provide double protection, which not only prevents sewage backflow but also avoids blockage of the return pipe, ensuring the long-term stable operation of the return system.

[0011] Please see Figure 1 The present invention provides an automated wear-resistant and corrosion-resistant variable frequency drainage water pump, including a base 1, a pump housing 2 fixedly connected to the inner side of the base 1, a drive component 3 fixedly connected to the top of the base 1, a water outlet 4 fixedly connected to the side of the pump housing 2, a water inlet 5 fixedly connected to the other side of the pump housing 2, and a filter component 6 fixedly connected to the side of the water inlet 5. Example 1, please refer to Figures 2-4 The present invention also includes a filter component 6 comprising a filter housing 61, the filter housing 61 being fixedly connected to the inlet end of the inlet 5, and a mesh plate 65 being fixedly connected to the inner side of the filter housing 61. A flow guiding mechanism 62 is rotatably connected to the water-facing surface of the mesh plate 65. After the sewage conveying pipe is connected to the filter housing 61, the sewage enters the filter housing 61 through the conveying pipe and first passes through the built-in flow guiding mechanism 62. The continuous impact of the water flow drives the flow guiding mechanism 62 to automatically clean the long fibers and strip-shaped debris attached to the water-facing surface of the mesh plate 65, thereby preventing the debris from covering the mesh plate 65 on a large area and causing a decrease in the flow area. A diversion mechanism 64 is fixedly connected to the inner side of the filter housing 61. Through the diversion mechanism 64, solid impurities intercepted by the screen 65 are collected in a directional manner to prevent impurities from accumulating on the water-facing surface of the screen 65 and to ensure the basic stability of the filtration flow. A connecting frame 69 is rotatably connected to the middle of the back surface of the mesh plate 65. A rotating blade 68 is fixedly connected to the other end of the connecting frame 69. The water filtered by the mesh plate 65 passes through the mesh holes and flows to the water pump inlet 5 at the rear end. During the process of the water flow passing through the mesh plate 65, it continuously impacts the rotating blade 68 set on the back surface of the mesh plate 65, driving the rotating blade 68 to rotate continuously. Guide blocks 613 are fixedly connected to both sides of the connecting frame 69, and the guide blocks 613 can contact and press the guide plate 612. The rotating blade 68 drives the guide blocks 613 at the end to rotate synchronously through the coaxially fixed connecting frame 69. During the rotation of the guide block 613, it forms a cyclic action of contact, squeezing and disengaging with the guide plates 612 set on both sides of the back surface of the mesh frame 66, pushing the guide plates 612 and the mesh frame 66 fixed thereto to move axially towards the mesh 65 along the sliding rods 610 fixed on both sides of the mesh 65. During the movement, the mesh frame 66 simultaneously presses against the first spring 611 sleeved on the slide rod 610 to complete the ejection stroke; On the side of the mesh frame 66 facing the mesh plate 65, there are fixed top rods 67 that correspond one-to-one with the mesh holes of the mesh plate 65. When the mesh frame 66 moves toward the mesh plate 65, the top rods 67 are simultaneously inserted into the corresponding mesh holes, pushing the impurities stuck in the mesh holes toward the water-facing side, thus completing the single-round mesh hole clearing. After the guide block 613 rotates and disengages from the guide plate 612, the compressed reset spring releases its elastic force, pushing the mesh frame 66 and the top rod 67 to retract and reset synchronously. As the rotating blade 68 continues to rotate, the guide block 613 continuously reciprocates and squeezes the guide plate 612, thereby driving the top rod 67 to continuously insert and withdraw within the mesh of the mesh plate 65, thus achieving active unblocking of the mesh of the mesh plate 65. Example 2, please refer to Figures 5-6 The invention also includes a flow guiding mechanism. Urban sewage is continuously fed into the inner cavity of the filter housing 61 through the sewage conveying pipe. The continuous impact force generated by the flowing sewage directly acts on the flow guiding blades 621 set on the water-facing surface of the mesh plate 65. A fixed blade 624 is fixedly connected to the side of the fixed shaft 625, and a guide vane 621 is rotatably connected to the other end of the fixed shaft 625. After being impacted by the water flow, the guide vane 621 rotates continuously around the fixed shaft 625, and drives the scrapers 623 on both sides of it to make a circular following motion through the connecting rod 622. The scraper 623 has a special gripping groove on its surface. During rotation, the groove can actively grip and wrap around long, flexible impurities in the sewage, preventing the long impurities from directly adhering to the covering mesh 65 and embedding into the mesh, thus avoiding blockage. As the guide vane 621 continues to rotate, the scraper 623, which is wrapped with long strips of impurities, forms a periodic shearing engagement with the fixed blade 624 fixedly installed on the side of the fixed shaft 625. The shearing force generated by the relative movement of the scraper 623 and the fixed blade 624 cuts the long strips of impurities wrapped on the scraper 623 into short fragments, completing the online crushing process of long strips of impurities and avoiding the risk of blockage caused by long impurities. Example 3, please refer to Figures 7-8 The invention also includes a diversion mechanism, in which urban sewage is continuously fed into the inner cavity of the filter housing 61 through a conveying pipeline, and the impact force of the flowing sewage drives the guide vanes 621 on the water-facing surface of the mesh plate 65 to rotate continuously. A sliding block 642 is slidably connected to the inner side of the sliding sleeve 641. The sliding block 642 is horizontally set with the guide vane 621. A square plate is fixedly connected to the side of the sliding block 642, and the guide vane 621 can contact the square plate when it rotates. A sliding rod 649 is fixedly connected to the side of the sliding block 642. The other end of the sliding rod 649 is slidably connected to the inner side of the sliding sleeve 641. A second spring 650 is sleeved on the sliding rod 649. One end of the second spring 650 is fixedly connected to the sliding block 642, and the other end of the second spring 650 is fixedly connected to the inner side of the sliding sleeve 641. During the rotation of the guide vane 621, a periodic contact, squeezing and disengaging cycle is formed with the square plate fixed to the side of the sliding block 642. When the guide vane 621 presses against the square plate, it pushes the sliding block 642 and the sliding rod 649 to slide directionally along the axis of the sliding sleeve 641, and simultaneously compresses the second spring 650. At this time, the relative displacement between the sliding block 642 and the sliding sleeve 641 forms an openable and closable diversion notch, thus completing the opening of the diversion channel. After the diversion gap is opened, the sewage containing a large amount of solid impurities near the water-facing surface of the screen plate 65, which has been intercepted by the screen plate 65, is rotated and guided by the guide vane 621 and enters the interior of the sliding sleeve 641 through the diversion gap. The top of the sliding sleeve 641 is provided with a flow direction hole 643, which faces the collection tank 644. The inner side of the filter housing 61 is provided with a collection tank 644 and a diversion tank 645. The side of the collection tank 644 is evenly provided with through holes 646. The inner side of the collection tank 644 is fixedly connected with a return pipe 647. Subsequently, the wastewater containing impurities is directed into the matching impurity collection tank 644 through the through hole 646 opened at the top of the sliding sleeve 641, so as to achieve the separation of intercepted impurities from the mainstream filtered water and prevent impurities from continuously accumulating on the water-facing surface of the screen plate 65. After the wastewater containing impurities enters the collection tank 644, solid-liquid separation is achieved through the through hole 646. Solid impurities are intercepted and retained in the collection tank 644, while the filtered clean water enters the diversion tank 645. Clean water is guided into the return pipe 647 through the diversion channel 645, and finally returns to the area inside the filter housing 61 away from the screen plate 65, thus completing the reuse of clean water; When the guide vane 621 rotates and disengages from the squeezing contact with the square plate, the compressed second spring 650 releases its elastic force, pushing the sliding rod 649 and the sliding block 642 to slide back and reset, closing the diversion gap, and waiting for the next squeezing trigger of the guide vane 621 to form an uninterrupted periodic diversion and collection operation. A one-way outlet valve is provided inside the return pipe 647, and a filter screen 648 is fixedly connected inside the return pipe 647. The return pipe 647 is equipped with a filter screen 648 and a one-way outlet valve. The filter screen 648 can prevent fine impurities that are not completely intercepted from entering the return pipe 647 and causing blockage. The one-way outlet valve only allows clean water to flow from the diversion tank 645 to the front end of the filter housing 61 in one direction, eliminating the risk of sewage and impurities flowing back into the diversion tank 645 through the return pipe 647. Specific workflow: First, by deploying level, pressure, and flow sensors at water collection wells and drainage pipe networks, front-end operating data is collected in real time and transmitted synchronously to the central controller of the intelligent control cabinet. The controller performs intelligent calculations based on preset operating thresholds, drainage requirements, and real-time collected parameters, quickly generates appropriate start / stop and speed adjustment commands, and sends them to the frequency converter drive unit. The frequency converter drive unit then adjusts the output speed and operating power of the drive component 3. The impeller inside the pump casing 2 is driven to operate at a dynamically adjusted speed according to the working conditions. The impeller works to pressurize and transport the medium to be discharged, realizing real-time dynamic matching of drainage flow and head, and achieving energy saving and consumption reduction while ensuring drainage efficiency. During the continuous transport of the medium, the pump casing 2 flow-through components are made of high wear-resistant alloy, corrosion-resistant stainless steel and hard wear-resistant mechanical seal structure, which can simultaneously resist the long-term scouring and wear caused by mud and solid particles in the medium, as well as the chemical and electrochemical corrosion caused by acid and alkali corrosive media, ensuring the smooth flow of the flow channel and the sealing of the internal structure of the equipment throughout the process, and preventing the medium leakage from corroding the core operating components. Meanwhile, the built-in operation monitoring module of the equipment will collect core operating parameters such as motor temperature, vibration, current and voltage, and pump body sealing status in real time throughout the process. Once abnormal conditions such as overload, overheating, dry running, phase loss, and medium leakage are detected, the graded protection mechanism will be triggered immediately to automatically complete load reduction adjustment, audible and visual alarms, and even safe shutdown operations. After the sewage conveying pipe is connected to the filter housing 61, the sewage enters the filter housing 61 through the conveying pipe. First, it passes through the built-in flow guiding mechanism 62. The water flow continuously impacts and drives the flow guiding mechanism 62 to automatically clean the long fibers and strip-shaped debris attached to the water-facing surface of the mesh plate 65, so as to avoid the large area of ​​debris covering the mesh plate 65 and causing a decrease in the flow area. The diversion mechanism 64 collects solid impurities intercepted by the screen 65 in a directional manner, preventing impurities from accumulating on the water-facing surface of the screen 65 and ensuring the basic stability of the filtration flow. After being filtered by the mesh plate 65, the water flows through the mesh holes to the water pump inlet 5 at the rear end. As the water flows through the mesh plate 65, it continuously impacts the rotating blade 68 set on the back surface of the mesh plate 65, driving the rotating blade 68 to rotate continuously. The rotating blade 68 drives the guide block 613 at its end to rotate synchronously via the coaxially fixed connecting frame 69; During the rotation of the guide block 613, it forms a cyclic action of contact, squeezing and disengaging with the guide plates 612 set on both sides of the back surface of the mesh frame 66, pushing the guide plates 612 and the mesh frame 66 fixed thereto to move axially towards the mesh 65 along the sliding rods 610 fixed on both sides of the mesh 65. During the movement, the mesh frame 66 simultaneously presses against the first spring 611 sleeved on the slide rod 610 to complete the ejection stroke; On the side of the mesh frame 66 facing the mesh plate 65, there are fixed top rods 67 that correspond one-to-one with the mesh holes of the mesh plate 65. When the mesh frame 66 moves toward the mesh plate 65, the top rods 67 are simultaneously inserted into the corresponding mesh holes, pushing the impurities stuck in the mesh holes toward the water-facing side, thus completing the single-round mesh hole clearing. After the guide block 613 rotates and disengages from the guide plate 612, the compressed reset spring releases its elastic force, pushing the mesh frame 66 and the top rod 67 to retract and reset synchronously. As the rotating blade 68 continues to rotate, the guide block 613 continuously reciprocates and squeezes the guide plate 612, thereby driving the top rod 67 to continuously insert and withdraw within the mesh of the mesh plate 65, thus achieving active unblocking of the mesh of the mesh plate 65. Urban sewage is continuously fed into the inner cavity of the filter housing 61 through the sewage conveying pipe. The continuous impact force generated by the flowing sewage directly acts on the guide vanes 621 set on the water-facing side of the mesh plate 65. After being impacted by the water flow, the guide vane 621 rotates continuously around the fixed shaft 625, which synchronously drives the scraper 623 on both sides to make a circular following motion. The scraper 623 has a special gripping groove on its surface. During rotation, the groove can actively grip and wrap around long, flexible impurities in the sewage, preventing the long impurities from directly adhering to the covering mesh 65 and embedding into the mesh, thus avoiding blockage. As the guide vane 621 continues to rotate, the scraper 623, which is wrapped with long strips of impurities, forms a periodic shearing engagement with the fixed blade 624 fixedly installed on the side of the fixed shaft 625. The shearing force generated by the relative movement of the scraper 623 and the fixed blade 624 cuts the long strips of impurities wrapped on the scraper 623 into short fragments, completing the online crushing process of long strips of impurities and avoiding the risk of blockage caused by long impurities. Urban sewage is continuously fed into the inner cavity of the filter housing 61 through the conveying pipeline. The impact force of the flowing sewage drives the guide vanes 621 set on the water-facing side of the screen plate 65 to rotate continuously. During the rotation of the guide vane 621, a cyclic action of periodic contact, squeezing and disengagement is formed with the square plate fixed to the side of the sliding block 642. When the guide vane 621 presses against the square plate, it pushes the sliding block 642 and the sliding rod 649 to slide directionally along the axis of the sliding sleeve 641, and simultaneously compresses the second spring 650. At this time, the relative displacement between the sliding block 642 and the sliding sleeve 641 forms an openable and closable diversion notch, thus completing the opening of the diversion channel. After the diversion gap is opened, the sewage containing a large amount of solid impurities near the water-facing surface of the screen plate 65, which has been intercepted by the screen plate 65, is rotated and guided by the guide vane 621 and enters the interior of the sliding sleeve 641 through the diversion gap. Subsequently, the wastewater containing impurities is directed into the matching impurity collection tank 644 through the through hole 646 opened at the top of the sliding sleeve 641, so as to achieve the separation of intercepted impurities from the mainstream filtered water and prevent impurities from continuously accumulating on the water-facing surface of the screen plate 65. After the wastewater containing impurities enters the collection tank 644, solid-liquid separation is achieved through the through hole 646. Solid impurities are intercepted and retained in the collection tank 644, while the filtered clean water enters the diversion tank 645. Clean water is guided into the return pipe 647 through the diversion channel 645, and finally returns to the area inside the filter housing 61 away from the screen plate 65, thus completing the reuse of clean water; When the guide vane 621 rotates and disengages from the squeezing contact with the square plate, the compressed second spring 650 releases its elastic force, pushing the sliding rod 649 and the sliding block 642 to slide back and reset, closing the diversion gap, and waiting for the next squeezing trigger of the guide vane 621 to form an uninterrupted periodic diversion and collection operation. The return pipe 647 is equipped with a filter screen 648 and a one-way outlet valve. The filter screen 648 can prevent fine impurities that are not completely intercepted from entering the return pipe 647 and causing blockage. The one-way outlet valve only allows clean water to flow from the diversion tank 645 to the front end of the filter housing 61 in one direction, eliminating the risk of sewage and impurities flowing back into the diversion tank 645 through the return pipe 647.
