Description

Technical Field

[0001] This invention belongs to the technical field of filter purification, and more specifically, it relates to a metal powder sintered gradient filter purification device. Background Technology

[0002] In the field of seawater purification, sintered metal powder gradient filter cartridges are widely used in seawater desalination and marine seawater treatment due to their advantages such as high filtration accuracy, structural stability, and strong corrosion resistance. However, existing sintered metal powder gradient filter cartridge purification devices still have many technical pain points during long-term use, which seriously affect the operating efficiency and service life of the device.

[0003] First, seawater contains a large amount of salt, minerals, and suspended impurities. During the filtration process, these impurities easily adhere to the inner wall of the filter element, forming scale. Traditional devices mostly use fixed scraping structures or manual cleaning methods, which have a limited scraping range and make it difficult to achieve all-round, dead-angle-free cleaning of the inner wall of the filter element. This leads to the accumulation of dirt residue, gradually narrowing the filtration channel, thereby reducing the water flow rate and purification efficiency, and affecting the stable operation of the device. Existing devices lack an effective dirt collection and treatment mechanism. Loose dirt after scraping is easily dispersed and flowed back in the collection channel, or the small particles and poor flowability can cause pipe blockage. This not only fails to achieve thorough dirt removal but may also cause secondary pollution, further accelerating the scaling rate of the filter element and increasing the frequency of device maintenance.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a metal powder sintered gradient filter purification device in order to achieve a more practical and valuable purpose. Summary of the Invention

[0005] This invention provides a metal powder sintered gradient filter purification device to overcome the above-mentioned defects in the prior art.

[0008] In a further technical solution, the drive assembly includes a drive blade, the lower end of which is fixedly connected to a bidirectional threaded screw, and a lifting and rotating device is rotatably provided on the surface of the bidirectional threaded screw. The lifting and rotating device includes a bidirectional rotation drive assembly, which includes two sets of gear disks. The two sets of gear disks slide up and down on the surface of the bidirectional threaded screw, and two sets of auxiliary gears are provided between the two sets of gear disks, with a stirring and collecting device connected to their outer sides.

[0009] In a further technical solution, the stirring and collecting device includes an upper sewage discharge component, a lower collecting component is sleeved below the upper sewage discharge component, the upper sewage discharge component and the lower collecting component are connected to the auxiliary gear to achieve rotation, the upper sewage discharge component and the lower collecting component are provided with openings to allow sewage to enter and exit, and a hard scraper is fixedly connected to the outside of the upper sewage discharge component and the lower collecting component.

[0010] A further technical solution involves a dirt collector fixedly installed at the bottom of the central rotating assembly. The dirt collector includes two sets of central partitions, with several sets of X-shaped clumping collection devices arranged in an array between the two sets of central partitions. The lower end of each X-shaped clumping collection device is fixedly connected to a central partition, and a funnel-shaped clumping assembly is fixedly connected to the outer side of the central partition. A spherical rolling assembly is fixedly installed on the inner side of the funnel-shaped clumping assembly.

[0011] In a further technical solution, the spherical rolling assembly includes a central fixed rotating shaft, an arc-shaped swing rod sleeved in the middle of the central fixed rotating shaft, and a rolling ball fixedly connected to the end of the arc-shaped swing rod. The X-shaped collecting and agglomerating device and the funnel agglomerating assembly are provided with an inclined block on the inner side, and the inclined block is provided with a notch on the inner side. When the rolling ball rotates, it contacts the inclined block.

[0012] In a further technical solution, several sets of flow rate sensors are fixedly installed on the outside of the sintered filter element assembly. The several sets of flow rate sensors correspond to several sets of external windows. The flow rate sensors control the inflow and outflow of water through an improved algorithm.

[0013] In a further technical solution, the inner tube filter element includes a bottom ring plate, a wire mesh cylinder is fixedly connected above the bottom ring plate, an upper tube ring is fixedly connected to the upper end of the wire mesh cylinder, and the middle part of the bottom ring plate is rotatably connected to the bidirectional threaded screw.

[0014] In a further technical solution, the assembly equipment unit includes a mounting bracket, on which a water suction pump is fixedly mounted, and on which a drainage pump is also fixedly mounted.

[0015] In a further technical solution, the seawater purification device includes an outer casing, an inlet pump pipe fixedly connected to the upper end of the outer casing, a drain pump pipe fixedly connected to the lower end of the outer casing, the drain pump pipe being connected to the drain pump, and the inlet pump pipe being connected to the suction pump.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses a metal powder sintered gradient filter cartridge purification device. Through the bidirectional rotation and reciprocating motion design of the stirring and collecting device, it achieves thorough scraping of the filter cartridge's inner wall without dead angles, laying the foundation for subsequent sewage discharge. The stirring and collecting device, through the bidirectional threaded screw of the drive component and the gear transmission of the lifting and rotating device, drives the upper sewage discharge component and the lower collecting component to rotate in opposite directions and move up and down synchronously. The hard scraper on its outer side can fully adhere to the inner wall of the sintered filter cartridge component, efficiently scraping away the stubborn scale attached. Compared with the traditional fixed scraping structure, it completely eliminates the dead angles of dirt residue on the inner wall of the filter cartridge, effectively solving the problem of decreased filtration efficiency caused by dirt accumulation in traditional devices, and significantly extending the cleaning cycle of the filter cartridge.

[0017] This invention discloses a metal powder sintered gradient filter purification device. Through an X-shaped interception mechanism and a spherical rolling agglomeration structure in the dirt collector, it achieves efficient agglomeration of scraped dirt, ensuring thorough wastewater discharge. After the dirt is scraped by the stirring and collecting device, the dirt collector uses an X-shaped agglomeration device to initially intercept and collide with the loose dirt. The dirt is then guided through a funnel agglomeration component to the spherical rolling component area. The rolling and squeezing action of the rolling balls, driven by an arc-shaped swing arm, causes the loose dirt to form dense agglomerates. This prevents the dirt from dispersing and flowing back into the collection channel or clogging the pipes. The fluidity of the agglomerated dirt is significantly improved. Compared to devices without agglomeration design, this invention greatly optimizes the dirt collection effect, creating favorable conditions for subsequent rapid wastewater discharge.

[0018] This invention discloses a metal powder sintered gradient filter purification device that achieves thorough discharge of clumped dirt through a linked opening and closing design of the outer window and the stirring and collecting device, completing a closed-loop cleaning process. The folding louvers of the outer window are linked to the rigid scraper of the stirring and collecting device. During scraping and discharge, the scraper presses down on the rubber contact strip, causing the louvers to automatically open. Clumped dirt can then be quickly discharged through the dual channels of the window assembly and the opening of the stirring and collecting device. After scraping, the support reset tube drives the louvers to automatically close, ensuring the sealing of the filtration process. This linked design achieves a seamless connection between "scraping-clumping-discharge," significantly improving the thoroughness of discharge compared to traditional single discharge channels, effectively preventing seawater leakage during discharge, ultimately ensuring long-term stable operation of the device, reducing the frequency of filter replacement, and significantly lowering operating costs.

The stirring and collecting device 6 is equipped with a lifting and rotating device 7 and a dirt collector 8. The lifting and rotating device 7 works with the driving component 5 to achieve up and down reciprocating motion and scrape dirt from the inner wall of the sintered filter element component 4. The dirt collector 8 collects dirt and the collected dirt clumps together. The clumping process can prevent dirt from sticking and clogging in the collection channel and improve the smoothness of sewage discharge. The sintered filter element assembly 4 is provided with an outer window 42. The outer window 42 works in conjunction with the stirring and collecting device 6 to open and discharge sewage. Through linkage control, the opening of the window and the scraping action are synchronized to ensure that the dirt after scraping is discharged in time and to avoid secondary adhesion.

[0029] Preferred options are shown in the appendix. Figure 12The sintered filter element assembly 4 includes a filter element inner cylinder assembly 41. The surface of the filter element inner cylinder assembly 41 is provided with several sets of window opening assemblies 421. A support and reset tube 423 is installed inside each window opening assembly 421. One end of the support and reset tube 423 is fixedly connected to the bottom of the filter element inner cylinder assembly 41. A folding louver 422 is fixedly installed on the outside of the support and reset tube 423. A rubber contact strip 424 is fixedly connected to the upper end of the folding louver 422. The support and reset tube 423 is made of an elastic reset material, which can drive the folding louver 422 to automatically close after the stirring and collecting device 6 moves upward, ensuring that seawater does not leak from the window opening assembly 421 during the filtration process. The rubber contact strip 424 is made of wear-resistant and corrosion-resistant rubber, ensuring a sealing effect when in contact with the hard scraper 64, reducing wear on the scraper, and extending the service life of the component.

[0030] Preferred options are shown in the appendix. Figure 6 The drive assembly 5 includes a drive blade 51, and a bidirectional threaded screw 52 is fixedly connected to the lower end of the drive blade 51. A lifting and rotating device 7 is rotatably mounted on the surface of the bidirectional threaded screw 52. The lifting and rotating device 7 includes a bidirectional rotation drive assembly 72, which includes two sets of gear disks. The two sets of gear disks slide up and down on the surface of the bidirectional threaded screw 52. Two sets of auxiliary gears are provided between the two sets of gear disks, and a stirring and collecting device 6 is connected to the outside. The drive blade 51 adopts a streamlined structure design and can be driven by the kinetic energy of seawater flow, eliminating the need for an additional power source and achieving energy-saving operation. The threads of the bidirectional threaded screw 52 are symmetrically arranged, ensuring that the two sets of gear disks drive the upper sewage discharge assembly 61 and the lower collection assembly 62 to rotate in opposite directions. This, together with the hard scraper 64, forms an all-round scraping of the inner wall of the filter element, avoiding dead corners where dirt remains.

[0031] Preferred options are shown in the appendix. Figure 8 The stirring and collecting device 6 includes an upper sewage discharge component 61, with a lower collecting component 62 sleeved below it. The upper sewage discharge component 61 and the lower collecting component 62 are connected to an auxiliary gear to achieve rotation. Openings 63 are provided on both the upper sewage discharge component 61 and the lower collecting component 62 for sewage inlet and outlet. A rigid scraper 64 is fixedly connected to the outer side of the upper sewage discharge component 61 and the lower collecting component 62. The rigid scraper 64 is made of high-hardness alloy material, and its scraper edge is designed with an acute angle to effectively cut and scrape away stubborn scale adhering to the inner wall of the filter element. The opening 63 has a funnel-shaped structure with a guide slope on the inner side, facilitating the rapid entry of dirt into the collection channel while reducing water flow resistance and ensuring that the purification efficiency is not affected.

[0032] Preferred options are shown in the appendix. Figure 1 To be continued Figure 13The bottom of the central rotating assembly 71 is fixedly equipped with a dirt collector 8. The dirt collector 8 includes two sets of central partitions 83. Between the two sets of central partitions 83, several sets of X-shaped collecting and agglomerating devices 81 are arranged in an array. The lower end of the X-shaped collecting and agglomerating device 81 is fixedly connected to the central partition 83. The outer side of the central partition 83 is fixedly connected to a funnel agglomerating assembly 82. The inner side of the funnel agglomerating assembly 82 is fixedly installed with a spherical rolling assembly 84. The cross structure of the X-shaped collecting and agglomerating device 81 can intercept and collide with the flowing dirt, promoting the aggregation of dirt particles. The funnel agglomerating assembly 82 has an inverted cone design, which uses gravity to guide the dirt to gather towards the center. Combined with the squeezing action of the spherical rolling assembly 84, it makes the loose dirt form a dense agglomerate, reducing the risk of dirt dispersion and backflow during the sewage discharge process.

[0033] Preferred options are shown in the appendix. Figure 13 To be continued Figure 14 The spherical rolling assembly 84 includes a central fixed rotating shaft 841, with an arc-shaped swing rod 842 sleeved in the middle of the central fixed rotating shaft 841. A rolling ball 843 is fixedly connected to the end of the arc-shaped swing rod 842. An inclined block 845 is provided inside the X-shaped collecting and clumping device 81 and the funnel-shaped clumping assembly 82. A notch 844 is provided inside the inclined block 845. The rolling ball 843 contacts the inclined block 845 when rotating. The arc-shaped swing rod 842 can generate centrifugal oscillation with the rotation of the central rotating assembly 71, driving the rolling ball 843 to roll and squeeze the dirt. The squeezed clumped dirt is directionally discharged through the notch 844 to the outside of the central partition 83, achieving orderly collection and discharge of dirt and preventing clumping from blocking the collection channel.

[0034] Preferred options are shown in the appendix. Figure 6 Several sets of flow rate sensors are fixedly installed on the outside of the sintered filter element assembly 4. These flow rate sensors correspond to several sets of external openings 42. The flow rate sensors control the inflow and outflow of water through an improved algorithm. The flow rate sensors monitor the water flow velocity in the seawater purification device 2 in real time. When the flow rate is detected to be lower than a preset threshold, it is determined that the accumulation of dirt on the inner wall of the filter element has reduced the flow cross-section. At this time, the improved algorithm automatically increases the inflow of water pump 13, enhances the driving force of water flow on drive blade 51, and accelerates the scraping frequency of stirring and collecting device 6. When the flow rate returns to the normal range, the inflow is automatically adjusted to the optimal value, which ensures the scraping effect and avoids energy waste, realizing intelligent adaptive control.

[0035] Preferred options are shown in the appendix. Figure 4The inner tube filter element 3 includes a bottom ring plate 32, with a wire mesh cylinder 33 fixedly connected above the bottom ring plate 32. An upper tube ring 31 is fixedly connected to the upper end of the wire mesh cylinder 33. The middle part of the bottom ring plate 32 is rotatably connected to the bidirectional threaded screw 52. The wire mesh cylinder 33 is woven from high-mesh stainless steel wire, possessing good support strength and filtration accuracy. It effectively protects the sintered filter element assembly 4, preventing deformation due to water flow impact or scraping action. A wear-resistant bearing is provided at the connection between the bottom ring plate 32 and the bidirectional threaded screw 52, ​​reducing rotational friction resistance and improving the operational stability and service life of the drive assembly 5.

[0036] Preferred options are shown in the appendix. Figure 1 The assembly unit 1 includes a mounting bracket 11, on which a water suction pump 13 and a drainage pump 12 are fixedly mounted. The mounting bracket 11 adopts a modular design, facilitating disassembly, maintenance, and transportation of the equipment. The water suction pump 13 and drainage pump 12 feature corrosion-resistant pump body structures suitable for seawater environments. Furthermore, their power parameters are matched to ensure a balance between inlet and outlet water rates, preventing excessively high or low water pressure within the device and ensuring stable operation of the purification process.

[0037] Preferred options are shown in the appendix. Figure 2 The seawater purification device 2 includes an outer casing 21. An inlet pump pipe 22 is fixedly connected to the upper end of the outer casing 21, and a drain pump pipe 23 is fixedly connected to the lower end of the outer casing 21. The drain pump pipe 23 is connected to the drain pump 12, and the inlet pump pipe 22 is connected to the suction pump 13. The outer casing 21 is made of corrosion-resistant metal material, and its inner wall is coated with an anti-corrosion coating to extend the overall service life of the equipment. A sealing gasket is provided at the interface between the inlet pump pipe 22 and the drain pump pipe 23 to ensure a tight connection and prevent seawater leakage. The diameter of the drain pump pipe 23 is designed to match the maximum particle size of the clumped dirt, ensuring that the clumped dirt can be discharged smoothly while reducing pipeline resistance.

[0038] Specific usage of this invention: When using this metal powder sintered gradient filter cartridge purification device, first connect the seawater purification device 2 of the assembly unit 1 to the suction pump 13 via the inlet pump pipe 22, and achieve a sealed connection with the drainage pump 12 via the drain pump pipe 23 to ensure that there is no leakage in the seawater delivery channel. After the device is assembled, start the suction pump 13, and the seawater will enter the seawater purification device 2 through the inlet pump pipe 22. After passing through the wire mesh cylinder 33 of the inner tube filter cartridge 3 to initially filter large particles of impurities, it enters the filter cartridge inner cylinder assembly 41 of the sintered filter cartridge assembly 4. Deep purification is achieved through the filter cartridge body of the metal powder sintered gradient structure. The purified seawater is finally discharged to the outside by the drainage pump 12 through the drainage pump pipe 23.

[0039] After prolonged use, traditional devices are prone to scale buildup on the inner wall of the filter cartridge inner cylinder assembly 41 of the sintered filter cartridge assembly 4. Long-term accumulation leads to narrowing of the filtration channel and reduced water flow velocity, thereby decreasing purification efficiency and increasing filter cartridge replacement costs. This device, however, solves this problem in real time through its built-in automatic cleaning system: when seawater flows through the inner side of the sintered filter cartridge assembly 4, the water flow impacts the drive blades 51 of the drive assembly 5, using the kinetic energy of the water flow to drive the drive blades 51 to rotate at high speed. The drive blades 51 then drive the bidirectional threaded screw 52 fixedly connected at the lower end to rotate synchronously. Because the bidirectional threaded screw 52 has symmetrically helical threads on its surface and forms a threaded engagement with the two sets of gear discs in the bidirectional rotation drive assembly 72 of the lifting and rotating device 7, when the bidirectional threaded screw 52 rotates, the two sets of gear discs slide up and down along the screw axis. Simultaneously, the two sets of auxiliary gears between the two sets of gear discs mesh and drive the outerly connected stirring and collecting device 6 to rotate synchronously. Furthermore, the upper sewage discharge assembly 61 and the lower collection assembly 62 rotate in opposite directions, forming an all-around scraping and covering effect.

[0040] During the reciprocating movement and reverse rotation of the stirring and collecting device 6, the rigid scraper 64 fixedly connected to its outer side will make close contact with the inner wall of the filter inner cylinder assembly 41. The inclined sharp edge of the rigid scraper 64 can effectively cut and scrape off the stubborn scale attached, avoiding the formation of dead corners due to dirt residue. When the stirring and collecting device 6 moves downward, the rigid scraper 64 on the outer side of the upper sewage discharge assembly 61 and the lower collecting assembly 62 will gradually come into contact with the rubber contact strip 424 of the outer window 42 of the sintered filter element assembly 4. With the continuous downward pressure, the folding louver 422 will be driven to fold and unfold along the support reset tube 423. At this time, the dirt scraped off will enter the sewage discharge channel through the open window assembly 421. When the stirring and collecting device 6 moves upward, the elastic reset force of the support reset tube 423 will drive the folding louver 422 to close automatically, and the rubber contact strip 424 will return to a sealed state, ensuring that seawater will not leak from the window assembly 421 during the filtration process.

[0041] The scraped dirt is collected and discharged in two parts: one part of the dirt enters the internal collection channel through the funnel-shaped opening 63 on the upper sewage discharge component 61 and the lower collection component 62 of the stirring collection device 6. The guide slope on the inside of the opening 63 can reduce water flow resistance and make the dirt flow into the dirt collector 8 quickly. After the dirt enters the dirt collector 8, it is first intercepted by the cross structure of the X-shaped collection and agglomeration device 81 and initially agglomerated by particle collision. Then, under the guidance of the inverted cone structure of the funnel agglomeration component 82, it converges towards the central spherical rolling component 84 area. Meanwhile, the central rotating component 71 drives the central fixed shaft 841 of the spherical rolling component 84 to rotate, and the arc-shaped swing arm 842 swings outward under the action of centrifugal force. The rolling ball 843 at the end rolls and contacts the surface of the inclined block 845, forming a squeezing force on the accumulated dirt, causing the loose dirt to form a dense clump. The clumped dirt is discharged through the notch 844 on the inner side of the inclined block 845 to the circular flow cavity on the outer side of the central partition 83, and then enters the central rotating component 71 through the central partition 83, and finally is discharged to the drain pump pipe 23 through the opening 63 of the upper sewage discharge component 61.

[0042] Another portion of the dirt enters directly into the gap between the outer shell 21 and the inner cylinder assembly 41 of the seawater purification device 2 through the opened window assembly 421, and eventually flows into the drain pump pipe 23, which is then discharged to the outside by the drain pump 12, thus achieving dual sewage discharge protection.

[0043] To ensure a dynamic balance between purification and cleaning processes, several sets of flow rate sensors installed on the outside of the sintered filter element assembly 4 correspond one-to-one with the outer window 42 to monitor the water flow velocity inside the seawater purification device 2 in real time. When the sensors detect that the flow rate is lower than a preset threshold, it is determined that the accumulation of dirt on the inner wall of the filter element has reduced the flow cross-section. At this time, an improved algorithm automatically sends an adjustment signal to the water pump 13 to increase the water intake to enhance the driving force of the water flow on the drive blades 51 and accelerate the scraping frequency of the stirring and collecting device 6. When the flow rate returns to the normal range, the algorithm automatically adjusts the water intake to the optimal value, ensuring both the scraping effect and avoiding energy waste, thus achieving intelligent adaptive control. The entire cleaning process requires no manual intervention and does not interrupt normal purification operations, ensuring the continuous and stable operation of the device.

[0044] Flow sensor acquisition algorithm: Step 1: Flow data acquisition and calibration. The sensor samples at high frequency and filters out abnormal values ​​to ensure the data is valid.

[0045] Step 2: Match parameters according to flow range: low flow, slow scraping with strong pressure; medium flow, regular scraping with pressure; high flow, fast scraping with weak pressure, and set the target clumping range accordingly.

[0046] Step 3: Dynamically correct parameters by fine-tuning the scraper speed and extrusion pressure based on real-time flow, calibrating the agglomeration volume, and matching the sewage discharge flow.

[0047] Step 4: The linkage action is executed. The stirring and collecting device 6 drives the hard scraper 64 to scrape the scale. The scale is collected through the opening 63 to the scale collector 8. The spherical rolling component 84 squeezes the clumps. The qualified clumps are discharged from the drain pump pipe 23 through the folding louver 422 and the rubber contact strip 424.

[0048] Step 5: Feedback closed-loop regulation. The pressure sensor monitors the clumping status and adjusts parameters in real time when there is blockage or loosening. Under normal conditions, the flow rate is collected and optimized in a loop.

[0049] On-site calibration: Fine-tuning of extrusion pressure and flow coefficient according to actual working conditions to ensure stable agglomeration. The assembly unit 1 coordinates the linkage of all components, and the drive component 5 provides power to ensure that the entire process adapts to flow rate and agglomeration requirements.
