Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and in particular to a wastewater treatment system and its wastewater treatment process. Background Technology

[0002] Wastewater treatment systems are facilities that purify polluted water through a series of treatment processes to a standard suitable for discharge into natural water bodies, irrigation fields, or reuse. Wastewater treatment processes include pretreatment, preliminary treatment, biological treatment, advanced treatment, and sludge treatment. However, depending on the specific nature of the wastewater, various combinations of processes may be used.

[0003] However, existing wastewater treatment systems are mostly customized equipment, which cannot be flexibly adjusted and used. They cannot be modularly assembled and used quickly after determining the treatment process based on the nature of the wastewater. Furthermore, existing wastewater treatment equipment is inconvenient to clean, and over time, excessive accumulation of dirt on the inner walls of the equipment will reduce the quality and effectiveness of wastewater treatment. Therefore, a wastewater treatment system and its treatment process are proposed. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a wastewater treatment system and its wastewater treatment process, which can flexibly and modularly combine multiple treatment cylinders according to the wastewater treatment process, and the treatment cylinders are easy to clean, thereby improving the quality and effect of wastewater treatment.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows: A wastewater treatment system includes a base, a treatment cylinder mounted on the base, a drain valve mounted at the bottom of the treatment cylinder, and a drive motor mounted at the upper end of the treatment cylinder. A rotating shaft is rotatably connected between the lower output end of the drive motor and the lower inner wall of the treatment cylinder. Multiple telescopic components are arrayed on the upper end of the treatment cylinder, and the lower ends of each telescopic component are connected to a filter ring. Multiple fan-shaped mesh surfaces are rotatably mounted on the filter ring. A rotating ring is rotatably fitted on the lower end of the filter ring, and multiple sliding frames arranged radially thereon are arrayed on the lower end of the rotating ring. Each sliding frame is connected to a collar at one end close to each other. Each sliding frame is slidably fitted with a limiting block and a cleaning scraper on the inner and outer sides of the collar. A sliding plate is provided at the lower end of the sliding frame. A sliding groove is arrayed on the outer side of the rotating shaft to cooperate with the limiting block. The slide plate is equipped with a drive assembly, which drives the limiting blocks on both sides of the slide frame to slide closer to or further away from the cleaning scraper. The slide plate is also equipped with a support assembly, which supports the fan-shaped mesh surface. The lower outer side of the rotating shaft is fitted with a spiral surface, and the outer side of the rotating shaft above the spiral surface is fitted with a disc. Slider blocks are arranged in an array on the disc, and connecting rods are connected to the sliders radially along the disc. Multiple fan-shaped scrapers are connected to the connecting rods at equal intervals, and an arc-shaped scraper is connected to the end of the rod. The disc and the slide plate are equipped with a linkage assembly, which drives the sliders to slide further away from each other when the collar moves down.

[0006] Preferably, the processing cylinder is fitted with an outer shell, the base is connected to the bottom of the inner shell, and the drain valve is located on one side of the spiral surface.

[0007] Preferably, a mounting frame is installed on the rear side of the processing cylinder, the drive motor is mounted on the mounting frame, and the upper ends of each of the telescopic components are mounted on the mounting frame and arranged in an array outside the drive motor.

[0008] Preferably, the lower ends of each of the telescopic components are connected to a ring, the filter ring is fitted on the outer side of the ring, the rotating ring is rotatably fitted on the lower end of the ring, the sliding frame has limit tracks on both the inner and outer sides along the radial direction of the collar, each limit track has a limit slider slidably fitted in it, the limit block and the cleaning scraper are respectively connected to the inner and outer limit sliders at opposite ends, and the collar has an opening that penetrates the limit track.

[0009] Preferably, the limiting insert slides through the inner limiting slide and the opening, and is inserted into the slide groove and slides along the axis of rotation in the slide groove. The cleaning scraper slides through the outer limiting slide and extends to the outside of the slide frame, and slides in close contact with the inner wall of the processing cylinder.

[0010] Preferably, the drive assembly includes a telescopic component two and a rotating plate one. The telescopic component two is centrally installed at the lower end of the slide frame between the two limiting slides. The slide plate is connected to the lower output end of the telescopic component two. The rotating plate one is rotatably connected to both ends of the inner and outer sides of the slide plate along the collar. The end of each rotating plate one away from the slide plate is rotatably connected to the limiting slider on its respective side.

[0011] Preferably, the support assembly includes a bracket and a push rod. The bracket is connected to both sides of each slide plate, and the push rod is connected to the upper end of each bracket and slides against the lower end of the fan-shaped mesh. Each fan-shaped mesh is rotatably connected to the filter ring mesh through a spiral hinge.

[0012] Preferably, the linkage component includes a connecting frame, a second circular ring, a second rotating ring, a slide rail, a second rotating plate, and a pressure ring. The connecting frame is connected to the lower end of the slide plate, the second circular ring is connected to the lower end of each connecting frame, the second rotating ring is rotatably fitted onto the lower end of the second circular ring, the slide rail array is opened through the disc, and the slider slides within the slide rail, the second rotating plate is rotatably connected to the upper end of the slider, the pressure ring is slidably disposed on the disc, and is rotatably connected to the end of each second rotating plate away from the slider, and the lower end of the second rotating ring is in contact with the upper end surface of the pressure ring.

[0013] Preferably, the lower end of the disk is connected to a plurality of guide rods arranged radially thereon, the slider is slidably sleeved on the outside of the guide rod on one side, the upper end of the slider slides through the slide rail on one side and is connected to the second rotating plate, the lower end of the pressure ring is connected to a plurality of limiting slide rods, and the lower end of each limiting slide rod extends through the disk to its lower end, and a spring sleeved on the outside of the limiting slide rod is connected between the pressure ring and the disk.

[0014] A wastewater treatment process includes the following steps: Step 1: When the treatment cylinder is used alone, the sewage is transported through the pipeline to the top of the filter ring to achieve preliminary filtration of the sewage. When too much filter material accumulates on the filter ring, it should be cleaned in time to ensure the pass-through of the filter ring. Step 2: Start the drive motor to rotate the shaft, which in turn rotates the disc, the spiral surface, and each fan-shaped scraper, stirring the sewage at the bottom of the treatment cylinder. This stirs up the sludge and sand at the bottom of the treatment cylinder, and the drain valve is opened in time to discharge the sludge and sand. Step 3: Add chemicals into the treatment cylinder to treat the sewage. Then, control the extension of the telescopic component to move each sliding frame down into the treatment cylinder. At the same time, control the drive component to move the limit blocks on both sides away from the cleaning scraper, so that the limit blocks can be inserted into the slide groove again and rotated by the rotating shaft. This will play a stirring role through the relevant structure on the sliding frame, and the extension and retraction of the telescopic component will realize rotation and synchronous up and down stirring. Step 4: After the limiting block and the cleaning scraper move away from each other, the cleaning scraper comes into contact with the inner wall of the treatment cylinder and performs a close scraping and cleaning of the inner wall of the treatment cylinder, ensuring the cleanliness of the inner wall of the treatment cylinder. When the sliding frame moves to the bottom of the treatment cylinder, it can drive the sliders to move away from each other through the linkage component, thereby causing each fan-shaped scraper to slide radially along the disc and scrape the bottom of the treatment cylinder. At the same time, the arc-shaped scraper can also scrape the arc angle between the bottom of the treatment cylinder and the side wall, achieving a comprehensive cleaning of the treatment cylinder. Step 5: Combine multiple processing cylinders for practical use, and connect each processing cylinder through pipes and solenoid valves to form a multi-processing cylinder processing module. Perform the operations of Step 1 to Step 4 in each processing cylinder, or perform any one or more of the operations of Step 1 to Step 4.

[0015] The beneficial effects of this invention are: 1. The technical solution of the present invention involves conveying sewage from above the filter ring, which can perform preliminary filtration of the sewage. At the same time, the drive motor drives the rotating shaft to rotate, which can drive the spiral surface at the bottom of the treatment cylinder to rotate, so that mud and sand can be stirred to the bottom of the treatment cylinder. Then, the sewage discharge valve can be controlled to open in time to discharge the mud and sand at the bottom of the sewage in time, thereby improving the preliminary treatment effect of the treatment cylinder. 2. The technical solution of the present invention controls the drive assembly to move the limit blocks on both sides away from the cleaning scraper, so that the limit blocks can be inserted into the slide groove opened on the rotating shaft. At the same time, the cleaning scraper can also move to the rotating cylinder that is in contact with the inner wall of the treatment cylinder. Then, when the rotating shaft rotates, it can control each slide frame to rotate synchronously, so that the slide frame has a stirring function to stir the sewage in the treatment cylinder, thereby improving the mixing efficiency when adding treatment agents. At the same time, it can also cooperate with the extension and retraction of the telescopic part one to drive the cleaning scraper to clean and scrape the inner wall of the treatment cylinder. When the slide frame moves to the bottom of the treatment cylinder, the rotating ring two mounted on it through the rotating ring two will abut against the pressure ring, pushing each fan-shaped scraper and arc-shaped scraper away from each other and scraping and cleaning the bottom of the treatment cylinder and the arc-shaped chamfer of the bottom and inner wall of the treatment cylinder, thereby achieving comprehensive cleaning of the treatment cylinder. This allows the treatment cylinder to perform multi-process treatment of sewage and has good cleanliness, improving the quality and effect of sewage treatment. 3. The technical solution of the present invention modularly combines multiple processing cylinders and outer shells, and connects them through pipes and solenoid valves, so that the processing cylinders can form a processing system with integrated multi-process processing capabilities, thereby improving the flexibility of equipment use.

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 9 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: like Figures 1-9 As shown, the present invention discloses a sewage treatment system, including a base 2, a treatment cylinder 3 installed on the base 2, a sewage discharge valve 5 installed at the bottom of the treatment cylinder 3, a drive motor 6 installed at the upper end of the treatment cylinder 3, a rotating shaft 7 rotatably connected between the lower output end of the drive motor 6 and the lower inner wall of the treatment cylinder 3, multiple telescopic components 9 are arrayed on the upper end of the treatment cylinder 3, and the lower ends of each telescopic component 9 are connected to a filter ring 11, multiple fan-shaped mesh surfaces 12 are rotatably arrayed on the filter ring 11, a rotating ring 13 is rotatably fitted at the lower end of the filter ring 11, and multiple sliding frames 14 arranged radially are arrayed on the lower end of the rotating ring 13, and a collar 15 is connected between the ends of each sliding frame 14 that are close to each other. Each sliding frame 14 is slidably fitted with a limiting insert 19 and a cleaning scraper 18 on the radial inner and outer sides of the collar 15, and a sliding plate 24 is provided at the lower end of the sliding frame 14. A sliding groove 21 that cooperates with the limiting insert 19 is arrayed on the outer side of the rotating shaft 7. A drive assembly is provided on the slide plate 24. The drive assembly is used to drive the limiting blocks 19 on both sides of the slide frame 14 and the cleaning scraper 18 to slide closer or further apart. A support assembly is also provided on the slide plate 24. The support assembly is used to support the fan-shaped mesh surface 12. A spiral surface 8 is fitted on the outer side of the lower end of the rotating shaft 7. A disc 22 is fitted on the outer side of the rotating shaft 7 above the spiral surface 8. Slider blocks 33 are arranged in an array on the disc 22. A connecting rod 34 is connected to the slider 33 radially along the disc 22. Multiple fan-shaped scrapers 35 are connected at equal intervals on the connecting rod 34. An arc-shaped scraper 36 is connected to the end of the connecting rod 34. A linkage assembly is provided on the disc 22 and the slide plate 24. The linkage assembly is used to drive each slider 33 to slide further apart when the collar 15 moves down.

[0020] The treatment cylinder 3 is fitted with an outer shell 1, and the base 2 is connected to the bottom of the outer shell 1. The drain valve 5 is located on one side of the spiral surface 8, so that when the rotating shaft 7 drives the spiral surface 8 to rotate, the mud and sand in the sewage can be stirred to the bottom of the sewage, that is, the bottom of the treatment cylinder 3, and the drain valve 5 can be opened in time by electrical control to discharge the mud and sand in the sewage in time.

[0021] A mounting frame 4 is installed on the rear side of the processing cylinder 3. The drive motor 6 is mounted on the mounting frame 4. The upper ends of each telescopic component 9 are mounted on the mounting frame 4 and arranged in an array outside the drive motor 6.

[0022] The lower ends of each telescopic component 9 are connected to a ring 10. The filter ring 11 is fitted on the outer side of the ring 10. The rotating ring 13 is rotatably fitted on the lower end of the ring 10. The sliding frame 14 has limit slides 16 on both the inner and outer sides of the collar 15. Each limit slide 16 is slidably fitted with a limit slider 17. The limit insert 19 and the cleaning scraper 18 are respectively connected to the inner and outer limit sliders 17 at opposite ends. The collar 15 has an opening 20 that penetrates the limit slide 16.

[0023] The limiting insert 19 slides through the inner limiting slide 16 and the opening 20, and is inserted into the slide groove 21. It slides along the axis of the rotating shaft 7 in the slide groove 21. The cleaning scraper 18 slides through the outer limiting slide 16 and extends to the outside of the slide frame 14, and slides in close contact with the inner wall of the treatment cylinder 3.

[0024] When the limiting block 19 and the cleaning scraper 18 are moved away from each other and inserted into the slide groove 21, the rotation of the rotating shaft 7 can drive each slide frame 14 and the rotating ring 13 to rotate, but the ring 10 does not rotate. When the telescopic member 9 is controlled to extend or retract, it can also pull the rotating ring 13 to slide up and down along the axis of the rotating shaft 7 while the rotating ring 13 rotates. The cleaning scraper 18 can also fit against the inner wall of the treatment cylinder 3 and perform a comprehensive up-and-down rotation and scraping of the inner wall of the treatment cylinder 3 to keep the inner wall of the treatment cylinder 3 clean and improve the quality and effect of sewage treatment.

[0025] Example 2: like Figures 1-9 As shown, the present invention discloses a wastewater treatment system. Compared with Embodiment 1, this embodiment discloses the structure of the drive component.

[0026] The drive assembly includes a telescopic component 23 and a rotating plate 25. The telescopic component 23 is centrally installed at the lower end of the slide frame 14 between the two limiting slides 16. The slide plate 24 is connected to the lower output end of the telescopic component 23. The rotating plate 25 is rotatably connected to both ends of the slide plate 24 along the inner and outer sides of the collar 15. The end of each rotating plate 25 away from the slide plate 24 is rotatably connected to the limiting slider 17 on its respective side.

[0027] By controlling the extension and retraction of the telescopic component 23, the sliding plate 24 can be controlled to slide, thereby driving the rotating plate 25 to rotate. The rotation of the rotating plate 25 pulls the limiting sliders 17 sliding in the limiting slide rails 16 on both sides of the sliding frame 14 to move closer or further away from each other, thereby driving the limiting blocks 19 on both sides and the cleaning scraper 18 to move closer or further away from each other.

[0028] Example 3: like Figures 1-9 As shown, the present invention discloses a sewage treatment system. Compared with Embodiment 2, this embodiment discloses the structure of the supporting components.

[0029] The support assembly includes a bracket 26 and a push rod 27. The bracket 26 is connected to both sides of each slide plate 24, and the push rod 27 is connected to the upper end of each bracket 26 and slides against the lower end of the fan-shaped mesh 12. Each fan-shaped mesh 12 is rotatably connected to the filter ring 11 through a spiral hinge.

[0030] When the telescopic component 23 retracts, it pulls the slide plate 24 upward, causing the limit blocks 19 on both sides and the cleaning scraper 18 to move away from each other. At this time, the slide frame 14 moves to the inner wall of the treatment cylinder 3 to agitate the sewage. The cleaning scraper 18 is in contact with the inner wall of the treatment cylinder 3 to scrape and clean the inner wall of the treatment cylinder 3. At the same time, the upward movement of the slide plate 24 can drive the push rod 27 to move upward and make contact with the fan-shaped mesh surface 12, so that the fan-shaped mesh surface 12 overcomes the spring hinge force and rotates upward, so that an opening 20 is created on the filter ring mesh 11. When the ring 10 is driven by the telescopic component 9 to agitate up and down in the sewage in the treatment cylinder 3, the opening 20 can improve the passage of sewage on the filter ring mesh 11 and reduce the resistance generated by the sewage when it moves up and down.

[0031] Example 4: like Figures 1-9 As shown, the present invention discloses a sewage treatment system. Compared with Embodiment 3, this embodiment discloses the structure of the linkage component.

[0032] The linkage components include a connecting frame 28, a second ring 29, a second rotating ring 30, a slide rail 32, a second rotating plate 37, and a pressure ring 38. The connecting frame 28 is connected to the lower end of the slide plate 24, the second ring 29 is connected to the lower end of each connecting frame 28, the second rotating ring 30 is rotatably fitted onto the lower end of the second ring 29, the slide rail 32 is arrayed and opened through the disc 22, and the slider 33 slides in the slide rail 32, the second rotating plate 37 is rotatably connected to the upper end of the slider 33, and the pressure ring 38 is slidably set on the disc 22 and rotatably connected to the end of each second rotating plate 37 away from the slider 33. The lower end of the second rotating ring 30 is in contact with the upper end surface of the pressure ring 38.

[0033] The lower end of the disc 22 is connected to a plurality of guide rod frames 31 arranged radially thereon. The slider 33 is slidably sleeved on the outside of the guide rod frame 31 on its respective side. The upper end of the slider 33 slides through the slide rail 32 on its respective side and is connected to the rotating plate 37. The lower end of the pressure ring 38 is connected to a plurality of limiting slide rods 39, and the lower end of each limiting slide rod 39 extends through the disc 22 to its lower end. A spring 40 sleeved on the outside of the limiting slide rod 39 is connected between the pressure ring 38 and the disc 22.

[0034] When the sliding frame 14 moves to the bottom of the treatment cylinder 3, the upper sliding plate 24 will contact the rotating ring 30 of the rotating set of the ring 29, thereby pushing the fan-shaped scrapers 35 and the arc-shaped scrapers 36 away from each other and scraping and cleaning the bottom of the treatment cylinder 3, as well as the arc-shaped chamfer of the bottom and inner wall of the treatment cylinder 3. In conjunction with the rotating shaft 7 driving the fan-shaped scrapers 35 and the arc-shaped scrapers 36 to rotate, the treatment cylinder 3 is thoroughly cleaned, enabling the treatment cylinder 3 to perform multi-stage treatment of sewage, and it has good cleanliness, thus improving the quality and effect of sewage treatment.

[0035] Example 5: like Figures 1-9 As shown, this invention discloses a wastewater treatment process, including the following steps: Step 1: When the treatment cylinder 3 is used alone, the sewage is transported through the pipeline to the top of the filter ring 11 to achieve preliminary filtration of the sewage. When too much filter material accumulates on the filter ring 11, it should be cleaned in time to ensure the passivity of the filter ring 11. Step 2: Start the drive motor 6 to drive the rotating shaft 7 to rotate, and drive the disc 22, the spiral surface 8 and each fan-shaped scraper 35 to rotate, stirring the sewage at the bottom of the treatment cylinder 3, so that the mud and sand are at the bottom of the treatment cylinder 3 due to the stirring, and promptly control the sewage pipe valve 5 to open and discharge the mud and sand. Step 3: Add chemicals into the treatment cylinder 3 to treat the sewage. Then, control the extension of the telescopic component 9 to move each sliding frame 14 down into the treatment cylinder 3. At the same time, control the drive component to move the limit blocks 19 on both sides away from the cleaning scraper 18, so that the limit blocks 19 can be inserted into the slide groove 21 again and rotated by the rotating shaft 7. The relevant structure on the sliding frame 14 plays a stirring role, and the extension and retraction of the telescopic component 9 realizes rotation and synchronous up and down stirring. Step 4: After the limiting block 19 and the cleaning scraper 18 move away from each other, the cleaning scraper 18 fits against the inner wall of the treatment cylinder 3 and performs a scraping cleaning of the inner wall of the treatment cylinder 3, ensuring the cleanliness of the inner wall of the treatment cylinder 3. When the sliding frame 14 moves to the bottom of the treatment cylinder 3, it can drive the sliders 33 to move away from each other through the linkage component, thereby causing each fan-shaped scraper 35 to slide radially along the disc 22 and scrape the bottom of the treatment cylinder 3. At the same time, the arc-shaped scraper 36 can also scrape the arc angle between the bottom and the side wall of the treatment cylinder 3, achieving a comprehensive cleaning of the treatment cylinder 3. Step 5: Combine multiple processing cylinders 3 for practical use, and connect each processing cylinder 3 through pipes and solenoid valves to form a multi-processing cylinder 3 processing module. Perform the operations of Step 1 to Step 4 in each processing cylinder 3, or perform any one or more of the operations of Step 1 to Step 4.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.

9. A wastewater treatment system according to claim 8, characterized in that, The lower end of the disc (22) is connected to a plurality of guide rod frames (31) arranged radially thereon. The slider (33) is slidably sleeved on the outside of the guide rod frame (31) on one side. The upper end of the slider (33) slides through the slide rail (32) on one side and is connected to the rotating plate (37). The lower end of the pressure ring (38) is connected to a plurality of limiting slide rods (39), and the lower end of each limiting slide rod (39) extends through the disc (22) to its lower end. A spring (40) sleeved on the outside of the limiting slide rod (39) is connected between the pressure ring (38) and the disc (22).

10. A wastewater treatment process, based on a wastewater treatment system according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: When the treatment cylinder (3) is used alone, the sewage is transported through the pipeline to the top of the filter ring (11) to achieve preliminary filtration of the sewage. When too much filter material accumulates on the filter ring (11), it should be cleaned in time to ensure the passability of the filter ring (11). Step 2: Start the drive motor (6) to drive the rotating shaft (7) to rotate, and drive the disc (22), spiral surface (8) and each fan-shaped scraper (35) to rotate, stirring the sewage at the bottom of the treatment cylinder (3), so that the mud and sand are at the bottom of the treatment cylinder (3) due to the stirring, and promptly control the sewage discharge valve (5) to open and discharge the mud and sand; Step 3: Add chemicals into the treatment cylinder (3) to treat the sewage. Then, control the extension of the telescopic component (9) to move each slide frame (14) down into the treatment cylinder (3). At the same time, control the drive component to move the limit blocks (19) on both sides away from the cleaning scraper (18), so that the limit blocks (19) can be inserted into the slide groove (21) again and rotated by the rotating shaft (7) to play a stirring role through the relevant structure on the slide frame (14). And through the extension and retraction of the telescopic component (9), the rotation and up and down synchronous stirring are achieved. Step 4: After the limiting block (19) and the cleaning scraper (18) move away from each other, the cleaning scraper (18) fits against the inner wall of the treatment cylinder (3) and performs a scraping cleaning of the inner wall of the treatment cylinder (3) to ensure the cleanliness of the inner wall of the treatment cylinder (3). When the sliding frame (14) moves to the bottom of the treatment cylinder (3), it can drive each slider (33) to move away from each other through the linkage component, thereby causing each fan-shaped scraper (35) to slide radially along the disc (22) and scrape the bottom of the treatment cylinder (3). At the same time, the arc-shaped scraper (36) can also scrape the arc angle between the bottom and the side wall of the treatment cylinder (3) to achieve a comprehensive cleaning of the treatment cylinder (3). Step 5: Combine multiple processing cylinders (3) for practical use, and connect each processing cylinder (3) with a pipe and a solenoid valve to form a multi-processing cylinder (3) processing module. Perform the operations of Step 1 to Step 4 in each processing cylinder (3), or perform any one or more of the operations of Step 1 to Step 4.
