Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a reciprocating scraper-suction sludge integrated machine for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of removing pollutants, such as organic matter, suspended solids, nitrogen, phosphorus, and heavy metals, from wastewater through physical, chemical, and biological methods, so that the treated water meets discharge standards or reuse requirements. It is a crucial link in protecting water resources, preventing water pollution, and maintaining ecological balance, and is widely used in municipal life, industrial production, agriculture, and aquaculture to prevent pollution of water bodies, rivers, lakes, and groundwater.

[0003] Sedimentation is a crucial step in wastewater treatment, separating sludge from water, and its operational status directly impacts effluent quality. With advancements in wastewater treatment technology, various high-efficiency sedimentation tanks have emerged.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 This invention provides a reciprocating sludge scraper / suction integrated machine for sewage treatment, comprising: A horizontal component 1 is used for reciprocating movement. A lifting component 2 is slidably connected to the inner side of the horizontal component 1, and a suction component 3 is fixedly connected to the top of the lifting component 2. The sludge scraping component 5 is used to adapt to sedimentation tanks of different shapes and to scrape the sludge. The side of the sludge scraping component 5 is slidably connected to the inside of the lifting component 2. In use, the horizontal component 1 is placed across the sedimentation tank, and the lifting component 2 drives the scraping component 5 to descend to the bottom of the tank. The scraping component 5 is first adjusted to fit the different shapes of the sedimentation tank. After the sewage in the sedimentation tank has settled for a period of time and the sludge thickness at the bottom of the tank reaches the set value, the scraping component 5 is activated to scrape and clean the sludge accumulated in the tank. At the same time, the suction component 3 is activated to suck up and process the scraped sludge.

[0022] Please see Figures 1-2 The horizontal component 1 includes two bottom housings 11. A lead screw 12 is rotatably connected to the inner side of the bottom housing 11, and a drive component 13 is fixedly connected to the side of the bottom housing 11. The output end of the drive component 13 is fixedly connected to one end of the lead screw 12. The lifting component 2 includes two lifting housings 21. The bottom of the lifting housing 21 is slidably connected to the inner side of the bottom housing 11. The bottom of the lifting housing 21 is threadedly connected to the side of the lead screw 12. The top of the two lifting housings 21 is fixedly connected to a top plate 22. Both sides of the top of the top plate 22 are fixedly connected to a second driving component 23. The inner side of the lifting housing 21 is rotatably connected to a second lead screw 24. The output end of the second driving component 23 is fixedly connected to the top of the second lead screw 24. In use, the two bottom housings 11 are placed horizontally on both sides above the sedimentation tank. When the two drive components 13 are turned on, their output ends will drive the lead screw 12 to rotate inside the bottom housing 11. The lead screw 12 in the two bottom housings 11 will drive the lifting housing 21 to move back and forth inside the bottom housing 11. After the drive component 23 is turned on, its output end will drive the lead screw 24 to rotate inside the lifting housing 21. Then, the lead screw 24 will drive the scraping component 5 to move downward to the bottom of the sedimentation tank to clean the inside of the sedimentation tank.

[0023] Please see Figures 1-4 The scraping component 5 includes a connecting block 51. Both sides of the connecting block 51 are slidably connected to the inner sides of two lifting housings 21, and both sides of the connecting block 51 are threadedly connected to the sides of two lead screws 24. A bracket 510 is fixedly connected to the top of the connecting block 51, and a driving component 3 59 is fixedly connected to the top of the bracket 510. A gear 1 511 is rotatably connected to the top of the connecting block 51, and the top of the gear 1 511 is fixedly connected to the output end of the driving component 3 59. A gear 2 512 is rotatably connected to the middle of the top of the connecting block 51, and gear 1 511 and gear 2 512 mesh with each other. A rotating rod is rotatably connected to the middle of the inner side of the connecting block 51. 52. The top of the rotating rod 52 is fixedly connected to the inner side of the gear 2 512. The bottom of the rotating rod 52 is fixedly connected to the blocking mechanism 53. The middle of the rotating rod 52 is fixedly connected to two connecting rods 54 distributed vertically. Limiting holes are opened on both sides of the top of the upper connecting rod 54. Telescopic mechanisms 55 are fixedly connected to both sides of the telescopic mechanism 54. A scraper 56 is fixedly connected to the end of the telescopic mechanism 55 away from the connecting rod 54. Scraper sleeves 57 are fixedly connected to both sides of the blocking mechanism 53. The inner side of the scraper sleeve 57 is slidably connected to the side of the scraper 56. A limiting mechanism 58 is sleeved on the rotating rod 52 near the connecting block 51. When cleaning the sludge inside the sedimentation tank, adjustments can be made according to the different shapes of the sedimentation tank, as follows: When cleaning the rectangular sedimentation tank, the bottom sides of the limiting mechanism 58 are adjusted to abut against the limiting holes on the top sides of the connecting rod 54, thereby limiting and fixing the position of the rotating rod 52. Then, the scraper 56 moves to both sides of the sedimentation tank under the drive of the telescopic mechanism 55. The screw 24 drives the connecting block 51 to move continuously downward into the sedimentation tank, so that the bottom of the blocking mechanism 53 and the bottom of the scraper 56 abut against the bottom of the sedimentation tank. At the same time, the sides of the scraper 56 abut against the sides of the sedimentation tank through the telescopic mechanism 55. After that, the screw 12 drives the lifting housing 21 to move back and forth in the bottom housing 11, and the scraper 56 can clean and scrape the sludge accumulated in the sedimentation tank. When cleaning the circular sedimentation tank, first release the limiting mechanism 58 from limiting and fixing the rotating rod 52, then turn on the drive component 3 59. The output end of the drive component 3 59 drives the gear 1 511 to rotate on the connecting block 51. The gear 1 511 drives the gear 2 512 to mesh and rotate, so that the gear 2 512 drives the rotating rod 52 to rotate inside the connecting block 51. The rotating rod 52 drives the scraper 56 to clean the inside of the circular sedimentation tank through the connecting rod 54.

[0024] Please see Figures 1-4The limiting mechanism 58 includes a limiting frame 581, the middle of which is rotatably connected to the side of the rotating rod 52. Limiting rods 583 are fixedly connected to both sides of the top of the limiting frame 581. The top of the limiting rods 583 is slidably connected to the bottom of the connecting block 51. Magnets 582 are fixedly connected to both sides of the limiting frame 581. The bottom of the magnets 582 is adapted to the limiting hole, and the top of the magnets 582 is attracted to the inner side of the connecting block 51. When fixing the positions of the connecting rod 54 and the rotating rod 52, pull the limiting frame 581 so that it moves downward through the limiting rod 583, thereby allowing the magnet 582 to be inserted into the limiting holes on both sides of the top of the connecting rod 54. This completes the fixing of the positions of the connecting rod 54 and the rotating rod 52, ensuring that the connecting rod 54 and the rotating rod 52 are stable when cleaning the rectangular sedimentation tank, and avoiding the impact of shaking on the sludge scraping and suction effect. When it is necessary to release the limiting position of the connecting rod 54 and the rotating rod 52, the limiting bracket 581 is pulled to make the magnet 582 disengage from the limiting holes on both sides of the top of the connecting rod 54. At this time, the top of the magnet 582 is attracted and fixed to the inner side of the connecting block 51, thereby releasing the position limiting position of the connecting rod 54 and the rotating rod 52 so as to clean the inner side of the circular sedimentation tank.

[0025] Please see Figures 1-5 The telescopic mechanism 55 includes a telescopic housing 551, a round rod 554 slidably connected to the inner side of the telescopic housing 551, a baffle 552 fixedly connected to one end of the round rod 554 near the telescopic housing 551, a scraper 56 fixedly connected to one end of the telescopic housing 551 away from the round rod 554, a connecting rod 54 fixedly connected to the inner side of the connecting rod 54, a side of the baffle 552 slidably connected to the inner side of the telescopic housing 551, and a connecting spring 553 sleeved on the round rod 554, one end of the connecting spring 553 fixedly connected to the baffle 552, and the other end of the connecting spring 553 fixedly connected to the inner side of the telescopic housing 551. When the rotating rod 52 drives the connecting rods 54 on both sides into the sedimentation tank, the telescopic outer shell 551 set in the connecting rod 54 will slide along the round rod 554 under the action of the connecting spring 553, thereby driving the scraper 56 to abut against the inner side of the sedimentation tank, realizing adaptive adjustment, ensuring that the scraper 56 can fit tightly against the inner side of the sedimentation tank. At the same time, the side of the scraper 56 can slide and adjust in the scraper sleeve 57. The scraper sleeve 57 can prevent the scraper 56 from contacting and moving with the bottom of the sedimentation tank during adaptive adjustment, thus preventing residual gaps. It ensures that the scraper sleeve 57 always contacts and moves with the bottom of the sedimentation tank, preventing the scraper 56 from leaking sludge due to gaps when cleaning sludge.

[0026] Please see Figures 1-6The blocking mechanism 53 includes a blocking housing 531. The two sides of the blocking housing 531 are fixedly connected to two scraper sleeves 57 respectively. The top of the blocking housing 531 is fixedly connected to the bottom of the rotating rod 52. Both sides of the blocking housing 531 are provided with relief grooves 532. The inner side of the blocking housing 531 is fixedly connected to a scraper frame 534. The top of the blocking housing 531 is provided with a connection hole 533. After the rotating rod 52 drives the connecting rods 54 on both sides into the sedimentation tank, it will cause the bottom of the retaining shell 531 to abut against the bottom of the sedimentation tank cavity. When the suction component 3 performs suction work, since the retaining shell 531 has clearance grooves 532 on both sides, the sludge that has accumulated and been scraped off can be sucked into the retaining shell 531 through the clearance grooves 532. At the same time, the retaining shell 531 is equipped with a scraper frame 534 on the inner side. When the retaining shell 531 moves in contact with the bottom of the sedimentation tank cavity, the scraper frame 534 can clean the bottom of the tank to avoid any omissions in the cleaning work.

[0027] Please see Figures 1-7 The present invention provides a technical solution: the suction component 3 includes a suction pipe 31, a separation mechanism 33 is fixedly connected to the top of the suction pipe 31, the bottom of the suction pipe 31 is rotatably connected to the inner side of the connection hole 533, the side of the suction pipe 31 is rotatably connected to the inner side of the rotating rod 52, and a suction pump 32 is fixedly connected to the side of the suction pipe 31. When the scraper 56 cleans the sludge at the bottom of the sedimentation tank, the suction pump 32 is turned on. Under its action, the sludge scraped off the bottom of the tank will be continuously transported to the separation mechanism 33 through the suction pipe 31. The separation mechanism 33 will then separate and treat the sludge and the wastewater that enters with it.

[0028] Please see Figures 1-8 The separation mechanism 33 includes a separation housing 331, the bottom of which is fixedly connected to the top of the top plate 22. A spiral rod 332 is rotatably connected to the inner side of the separation housing 331. A motor 333 is fixedly connected to the side of the separation housing 331. The output end of the motor 333 is fixedly connected to one end of the spiral rod 332. A connecting pipe 336 is fixedly connected to the middle of the bottom of the separation housing 331. The side of the connecting pipe 336 is fixedly connected to the inner side of the top plate 22. A corrugated pipe 337 is fixedly connected to the bottom of the connecting pipe 336. The bottom of the corrugated pipe 337 is fixedly connected to the output end of the sewage pump 32. A sewage outlet pipe 334 is fixedly connected to the side of the separation housing 331. A drain pipe 335 is fixedly connected to the side of the separation housing 331 away from the motor 333. A filter screen is fixedly connected to the end of the drain pipe 335 near the separation housing 331. Under the action of the suction pump 32, the sludge is continuously transported upward through the suction pipe 31 and enters the separation shell 331 through the corrugated pipe 337 and the connecting pipe 336. At this time, the motor 333 is turned on, and the output end of the motor 333 drives the screw rod 332 to rotate inside the separation shell 331, performing spiral separation treatment on the incoming sludge: the sewage in the sludge flows back to the sedimentation tank through the drain pipe 335, and the end of the drain pipe 335 near the separation shell 331 is equipped with a filter screen to prevent sludge from entering the drain pipe 335, while the sludge is discharged through the sewage outlet pipe 334. The outlet of the sewage outlet pipe 334 is connected to an external pipe to allow the sludge to be continuously discharged, realizing the separation of sludge and sewage. In addition, the corrugated pipe 337 at the bottom of the connecting pipe 336 can be extended and retracted when the suction pipe 31 moves up and down with the connecting block 51, so as to avoid interfering with the height adjustment operation.

[0029] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
