Description

Technical Field

[0001] This invention relates to the field of multistage pump technology, specifically to a high-efficiency, energy-saving, self-balancing multistage pump. Background Technology

[0002] A self-balancing multistage pump is a device used for fluid transportation. Its core feature is that it achieves self-balancing during operation by optimizing the internal impeller structure. It has the advantages of high efficiency, energy saving, and stable operation, and is widely used in various fluid transportation scenarios.

[0003] However, some existing self-balancing multistage pumps lack a fluid filtration structure or only use a simple filtration structure such as a single filter screen. This can cause impurities in the fluid to easily enter the pump body, causing erosion and wear on the impeller, seals, and self-balancing mechanism. This results in decreased pump efficiency and increased energy consumption. Furthermore, the simple filtration structure with a single filter screen has poor fluid filtration effect, high filtration resistance, and is prone to clogging. It requires frequent shutdowns for maintenance, disassembly, and replacement, which is cumbersome, time-consuming, and seriously affects the continuous operating efficiency of the pump. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency, energy-saving, self-balancing multistage pump to solve the problems mentioned in the background art.

A set of first gears is connected to the front middle end of the second support panel, a set of second gears is connected to the top end of the first gear, and a set of second drive motors corresponding to the first gears is provided in the inner middle end of the second support panel.

[0012] By adopting the above technical solution, the second drive motor can be driven by the first gear to rotate the second gear, thereby achieving meshing transmission, which in turn drives the third gear, the central shaft and the rotating seat to rotate. This allows for quick switching between the upper and lower filter cartridges, realizing the function of flipping and switching the filter mechanism, and ensuring the continuity and convenience of cleaning operations.

[0014] By adopting the above technical solution, the rotating plate rotates around the fixed axis, and the linkage action is realized through the linkage groove and the linkage rod, so that the moving plate moves forward and pushes the filter cartridge in the lower installation groove forward, thereby improving the cleaning and replacement efficiency of the filter cartridge.

[0016] By adopting the above technical solution, the front end of the unloading panel can contact the rear end of the filter cartridge. When the moving plate pushes, it can ensure the smooth pushing of the filter cartridge and prevent the filter cartridge from tilting. The spring can provide the moving plate with the reset force, and it can automatically reset after the unloading operation is completed, ensuring the smooth and efficient unloading process.

[0017] Preferably, the filtration mechanism includes a rotating base, a mounting groove, a filter cylinder, and a central shaft. The rotating base has a set of mounting grooves at both its upper and lower ends, and a set of filter cylinders is connected to each mounting groove.

[0018] By adopting the above technical solution, the mounting slots at the upper and lower ends of the rotating seat are used to fix the filter cartridge. The central shaft drives the rotating seat to move up and down, realizing the connection or separation with the connecting pipe body. The modular design of the filter cartridge facilitates the installation, replacement and maintenance of the filter cartridge.

[0019] Preferably, all components of the filter cartridge are identical, the filter cartridge contains at least two sets of filter discs, and at least two sets of limiting protrusions are arranged at equal intervals on the outer side of the filter cartridge.

[0020] By adopting the above technical solution, the multiple filter discs inside the filter cartridge can achieve multi-stage filtration, effectively removing impurities of different particle sizes with high filtration accuracy. The limiting protrusions cooperate with the mounting groove for positioning, ensuring the filter cartridge is installed stably, preventing displacement during operation, improving maintenance convenience, and realizing high-precision fluid filtration and rapid positioning and installation of the filter cartridge.

Gear three can mesh with gear two, thereby achieving the flipping effect of the rotating seat through meshing transmission. The slider ensures the stability of the rotating seat when moving up and down. The overall structure is compact, the transmission path is clear and reliable, and it realizes the coordinated control of multiple actions of the filtration mechanism, improves the automation level and operational stability of the pretreatment mechanism, ensures the precise connection of actions such as embedding, separating, and flipping, and realizes the linkage control function of the up and down movement and flipping action of the filtration mechanism. Preferably, the inner side of the through hole at the rear end is provided with an internal thread.

[0023] By adopting the above technical solution, the internal thread is opposite to the lead screw, and when the lead screw rotates, the internal thread can drive the linkage plate, the central shaft and the rotating seat to move up and down.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a pretreatment mechanism located at the front end of the water inlet. The pretreatment mechanism includes components such as a connecting pipe, an inlet pipe, an outlet pipe, a first support panel, a second support panel, and a filtration mechanism. Combined with the filter disc inside the filter cylinder of the filtration mechanism, it can achieve the filtration and separation effect of impurities in the fluid. Furthermore, the mesh diameter of the filter disc gradually decreases from front to back, thereby achieving multi-stage high-precision filtration of the fluid. This effectively intercepts impurities of different particle sizes, optimizes the existing multi-stage pumps that lack an efficient pre-filtration structure, which leads to impurities entering the pump body and causing wear and blockage of pump components. This significantly extends the service life of the pump body, while ensuring the smoothness of fluid delivery and improving the operational stability and efficiency of the multi-stage pump. 2. The present invention uses a second support panel located at the rear end of the bottom surface of the connecting pipe body. The second support panel is equipped with components such as a drive mechanism, a flipping mechanism and a material ejection mechanism. Together with the mounting slots at the upper and lower ends of the rotating seat in the filter mechanism and the filter cylinder in the mounting slot, the filter components can be quickly switched and maintained, greatly reducing the number of manual steps, reducing the difficulty of maintenance, and shortening the downtime. This solves the pain point of the traditional multi-stage pump filter components being cumbersome to replace and affecting continuous operation. 3. The present invention utilizes a filtration mechanism disposed between support panel one and support panel two. The filtration mechanism includes components such as a rotating seat, a mounting groove, a filter cylinder, and a central shaft. The central shaft extends through both ends to the front and rear sides of the rotating seat and is connected to components such as a slider, a linkage plate, and a gear. With their cooperation, the rotating seat can achieve precise linkage of up-and-down movement and flipping, optimizing the cumbersome disassembly steps in the replacement and maintenance of existing filtration devices. At the same time, the modular design of the filter cylinder also improves the maintenance efficiency of the pretreatment mechanism, further enhancing the convenience of installation and maintenance.

[0029] Specifically, the pretreatment mechanism 4 installed at the front end of the inlet 3 can pre-treat and filter the fluid entering the pump body 1, preventing impurities from entering the pump body 1 and causing wear and blockage to the internal components of the pump body 1, thus effectively extending the service life of the pump body 1. The top of the filter mechanism 46 extends to the middle of the connecting pipe 41, located between the inlet pipe 42 and the outlet pipe 43, which can effectively intercept impurities in the fluid. The first support panel 44 and the second support panel 45 can support the connecting pipe 41 and are linked with the filter mechanism 46 through the second support panel 45, which facilitates the maintenance and replacement of the filter components, effectively extending the service life of the pump body 1 and improving the operational stability and efficiency of the pump body 1.

[0030] Please see Figures 2-4 A set of drive mechanisms 451 is provided at the top front of the support panel 45. The drive mechanism 451 can drive the filter mechanism 46 to move up and down.

[0031] Specifically, the drive mechanism 451 can provide power output, the flipping mechanism 452 can adjust the posture of the filter mechanism 46, and the unloading mechanism 453 can facilitate the separation of the filter components inside the filter mechanism 46. This can effectively reduce the number of manual steps involved in cleaning the filter mechanism 46, reduce maintenance difficulty, reduce the downtime of the pump body 1, and improve the continuous operating efficiency of the pump body 1.

[0032] Please see Figures 3-4 The drive mechanism 451 includes a drive groove 4511, a guide rod 4512, a lead screw 4513, and a drive motor 4514.

The top end of the drive shaft of the drive motor 4514 is fixedly connected to the bottom end of the lead screw 4513, which can drive the lead screw 4513 to rotate.

[0033] Specifically, the drive motor 4514 drives the lead screw 4513 to rotate, and the guide rod 4512 guides and limits the linkage plate 4642, providing stable up-and-down movement power for the filter mechanism 46. The transmission accuracy is high and the operation is smooth, ensuring the matching accuracy between the filter mechanism 46 and the connecting pipe body 41, and guaranteeing the filtration effect and the reliability of the cleaning action.

[0034] Please see Figures 3-4 The flipping mechanism 452 includes a first gear 4521, a second gear 4522, and a second drive motor 4523. A set of first gear 4521 is connected to the front middle end of the second support panel 45, and a set of second gear 4522 is connected to the top of the first gear 4521. The first gear 4521 and the second gear 4522 mesh with each other. The rotation of the first gear 4521 can drive the second gear 4522 to rotate. A set of second drive motors 4523 corresponding to the first gear 4521 is provided in the middle of the second support panel 45. The drive shaft of the second drive motor 4523 extends through to the front end of the second support panel 45 and is connected to the middle end of the first gear 4521, which can drive the first gear 4521 to rotate.

[0035] Specifically, the second drive motor 4523 can drive the second gear 4522 to rotate via the first gear 4521, thereby achieving meshing transmission, which in turn drives the third gear 4644, the central shaft 464, and the rotating seat 461 to rotate. This allows for quick switching between the upper and lower filter cartridges 463, realizing the function of flipping and switching the filter mechanism 46, ensuring the continuity and convenience of cleaning operations.

[0036] Please see Figures 3-5The unloading mechanism 453 includes a moving groove 4531, a moving plate 4532, a connecting groove 4533, a fixed shaft 4534, a rotating plate 4535, and a linkage groove 4536.

A torsion spring is provided at the connection between the fixed shaft 4534 and the rotating plate 4535. After the rotating plate 4535 rotates, it can be automatically reset by the elastic force of the torsion spring.

[0037] Specifically, the rotating plate 4535 rotates around the fixed shaft 4534, and achieves a linkage action with the linkage rod 45323 through the linkage groove 4536, so that the moving plate 4532 moves forward and pushes the filter cartridge 463 in the lower mounting groove 462 forward, thereby improving the cleaning and replacement efficiency of the filter cartridge 463.

[0038] Please see Figure 5 A set of ejector panels 45321 are fixedly connected to the front end of the movable plate 4532. The ejector panels 45321 are the same size as the outer diameter of the filter cartridge 463 and can fit against the rear end face of the filter cartridge 463. A second linkage groove 45322 is opened in the middle of the movable plate 4532. A set of linkage rods 45323 is provided at the rear end of the second linkage groove 45322. The left end of the rotating plate 4535 extends into the second linkage groove 45322, and the linkage rods 45323 are located in the first linkage groove 4536.

When the moving plate 4532 pushes, it can ensure the smooth pushing of the filter cartridge 463 and prevent the filter cartridge 463 from tilting. The spring 45325 can provide the moving plate 4532 with a reset force. After the unloading operation is completed, it can automatically reset, ensuring the smooth and efficient unloading process.

[0040] Please see Figure 3 , Figure 6 and Figure 7 The filtration mechanism 46 includes a rotating seat 461, a mounting groove 462, a filter cylinder 463 and a central shaft 464. The rotating seat 461 has a set of mounting grooves 462 at both the upper and lower ends, and a set of filter cylinders 463 are installed in each mounting groove 462. A central shaft 464 is installed in the middle of the rotating seat 461.

[0041] Specifically, the mounting slots 462 at the upper and lower ends of the rotating base 461 are used to fix the filter cartridge 463. The central shaft 464 drives the rotating base 461 to move up and down, so as to connect or separate it from the connecting pipe body 41. The modular design of the filter cartridge 463 facilitates the installation, replacement and maintenance of the filter cartridge 463. The two sets of filter cartridges 463 can work alternately, which can effectively improve the filtration efficiency and the convenience of cleaning, and realize the modular installation function of the filter assembly.

[0042] Please see Figure 3 , Figure 6 and Figure 7 All components of the filter cylinder 463 are identical. The inner diameter of the filter cylinder 463 is the same as the inner diameter of the inlet pipe 42 and the outlet pipe 43. The front and rear ends of the filter cylinder 463 are respectively fitted and connected to the opposite surfaces of the inlet pipe 42 and the outlet pipe, which is conducive to the passage of fluid. The filter cylinder 463 is provided with no less than two sets of filter discs 4631. Each filter disc 4631 is provided with a filter screen in the middle. The mesh diameter of the filter screen gradually decreases from front to back, which can realize multi-stage filtration. No less than two sets of limiting protrusions 4632 are arranged at equal intervals on the outer side of the filter cylinder 463. The inner side of the mounting groove 462 is provided with a limiting groove corresponding to the limiting protrusions 4632, which can ensure the stability of the filter cylinder 463 during installation and material removal.

[0043] Specifically, the multiple filter discs 4631 inside the filter cartridge 463 can achieve multi-stage filtration, effectively removing impurities of different particle sizes with high filtration accuracy. The limiting protrusions 4632 cooperate with the mounting groove 462 for positioning, ensuring the stable installation of the filter cartridge 463, preventing displacement during operation, improving maintenance convenience, and realizing high-precision filtration of fluids and rapid positioning and installation of the filter cartridge 463.

[0044] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7The central shaft 464 extends to the front end of the rotating seat 461 and is connected to a set of sliders 4641. The rear end face of the support panel 44 has guide grooves corresponding to the sliders 4641 to ensure the stability of the rotating seat 461 during movement. The rear end of the central shaft 464 extends into the drive groove 4511 and is connected to a set of linkage plates 4642. Both the front and rear ends of the linkage plate 4642 have a set of through holes 4643, which are respectively opposite to the guide rod 4512 and the lead screw 4513. Furthermore, the inner side of the rear through hole 4643 has an internal thread, which connects to the lead screw. With rods 4513 facing each other, when the lead screw 4513 rotates, it can drive the linkage plate 4642, the central shaft 464 and the rotating seat 461 to move up and down through the internal thread. The guide rod 4512 and the front through hole 4643 can enhance the stability during movement. A set of gear 3 4644 is sleeved at the rear end of the central shaft 464 near the rear end face of the rotating seat 461. Gear 3 4644 meshes with gear 2 4522, and the front end face of gear 3 4644 is fixedly connected to the rear end of the rotating seat 461. When gear 2 4522 rotates, gear 3 4644 can drive the rotating seat 461 to rotate.

[0045] Specifically, the linkage plate 4642 uses two sets of through holes 4643 to cooperate with the guide rod 4512 and the lead screw 4513 to achieve the lifting effect. The gear three 4644 can mesh with the gear two 4522, thereby realizing the flipping effect of the rotating seat 461 through meshing transmission. The slider 4641 ensures the stability of the rotating seat 461 when it moves up and down. The overall structure is compact and the transmission path is clear and reliable. It realizes the coordinated control of multiple actions of the filter mechanism 46, improves the automation level and operational stability of the pretreatment mechanism 4, ensures the precise connection of actions such as embedding, separating and flipping, and realizes the linkage control function of the up and down movement and flipping action of the filter mechanism 46.

[0046] This invention provides a high-efficiency, energy-saving, self-balancing multistage pump. Through a pretreatment mechanism 4 located at the front end of the inlet 3, the pretreatment mechanism 4 includes components such as a connecting pipe 41, an inlet pipe 42, an outlet pipe 43, a first support panel 44, a second support panel 45, and a filter mechanism 46. Combined with the filter disc 4631 within the filter cylinder 463 of the filter mechanism 46, it can achieve the filtering and separation effect of impurities in the fluid. Furthermore, the mesh diameter of the filter disc 4631 gradually decreases from front to back, thereby achieving multi-stage high efficiency in fluid filtration. Precision filtration effectively intercepts impurities of different particle sizes, optimizing the existing multistage pumps' lack of efficient pre-filtration structures. This addresses the problem of impurities entering the pump body 1, causing wear and blockage of pump body 1 components, significantly extending the service life of the pump body 1, while ensuring smooth fluid delivery and improving the operational stability and efficiency of the multistage pump. A second support panel 45, located at the rear end of the bottom surface of the connecting pipe 41, houses a drive mechanism 451, a tilting mechanism 452, and a material ejection mechanism 453. The filter mechanism 46, with its mounting slots 462 at both ends of the rotating seat 461 and the filter cartridge 463 within the mounting slots 462, enables rapid switching and maintenance of the filter components. This significantly reduces manual intervention, lowers maintenance difficulty, and shortens downtime, solving the pain points of cumbersome replacement of traditional multi-stage pump filter components that affect continuous operation. The filter mechanism 46, located between support panel 1 44 and support panel 2 45, includes components such as a rotating seat 461, mounting slots 462, filter cartridge 463, and central shaft 464. The central shaft 464 extends through both ends to the front and rear sides of the rotating seat 461 and connects to components such as a slider 4641, a linkage plate 4642, and a gear 3 4644. With their cooperation, the rotating seat 461 can move up and down and rotate precisely, optimizing the cumbersome disassembly steps in the replacement and maintenance of existing filter devices. At the same time, the modular design of the filter cartridge 463 also improves the maintenance efficiency of the pretreatment mechanism 4, further enhancing the convenience of installation and maintenance.
