Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular, to an integrated sewage treatment device. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people. An integrated sewage treatment device is a device that integrates a primary sedimentation tank, primary and secondary contact oxidation tanks, a secondary sedimentation tank, and a sludge tank. Blowing aeration is carried out in the primary and secondary contact oxidation tanks, effectively combining the contact oxidation method and the activated sludge method, having the advantages of both and overcoming their disadvantages, further improving the sewage treatment level. The carbon steel integrated sewage treatment device is equipped with underwater aeration. When treating sewage, the sewage flows into the aeration area from the top of the device. The aerator conducts underwater aeration and pushes and stirs the sewage, and the incoming sewage quickly mixes fully with the original mixed liquid, maximizing the adaptation to changes in the influent water quality.

[0015] 1. The present invention filters large particle dirt existing in sewage through a transmission filtering mechanism. First, connect the sewage pipe with the water inlet pipe, and then open the water inlet valve to discharge the sewage through the water inlet pipe into the interior of the sewage treatment equipment main body. At this time, by turning on the driving motor, the driving roller rotates. The outer wall of the driving roller meshes with the inner wall of the conveyor belt. Therefore, when the driving roller rotates, it drives the conveyor belt to perform a conveying operation. The sewage with dirt falls into the conveyor belt after passing through the water inlet pipe. The large particle dirt impurities are blocked at the top end of the conveyor belt through the filtering through holes on the conveyor belt. The large particle dirt impurities are conveyed to the collection bin through the conveying of the conveyor belt, and then fall into the interior of the collection bin. The collection bin conducts centralized collection. When it is necessary to clean the dirt inside the collection bin, the collection bin can be taken out from the installation groove for cleaning operations, thereby completing the first large particle dirt filtering treatment operation for the sewage.

[0016] 2. When the filter through-holes on the conveyor belt are blocked and need to be cleaned, the cleaning mechanism can be used to clean the blockages in the filter through-holes on the conveyor belt. When cleaning the blockages in the filter through-holes on the conveyor belt is required, first, one end of the cleaning pipe can be connected to the water suction pipe. During the cleaning operation, by opening the cleaning valve, the cleaning water can enter the interior of the cleaning pipe through the water suction pipe, and then be sprayed out through multiple high-pressure nozzles at the top of the cleaning pipe. Through the spraying of the high-pressure nozzles, the blockages in the filter through-holes on the conveyor belt are washed away, thereby cleaning the dirt blockages in the filter through-holes. At the same time, before the cleaning operation, the limit sliders on the collection plate can be inserted into the limit sliding grooves at the bottom of the cleaning pipe, and then the collection plate can be inserted and installed inside the conveyor belt. When flushing the conveyor belt, the dirt attached to the inner wall of the conveyor belt can also be washed at the same time. The collection plate can collect the dirt on the inner wall of the conveyor belt when flushing the inner wall of the conveyor belt, preventing the dirt on the inner wall of the conveyor belt from falling onto the bottom conveyor belt after flushing. When the dirt on the collection plate needs to be cleaned, by pulling the pull handle by hand, the collection plate can be pulled out from the interior of the sewage treatment equipment main body, facilitating the cleaning operation of the dirt collected on the collection plate.

[0017] After the first filtration operation of the sewage in the present invention, the sewage after the first filtration will fall onto the repeated filtration mechanism at the bottom, and the repeated filtration mechanism performs a secondary filtration operation on the sewage. When the sewage passes through the filter through-holes for the first filtration, it will fall downward onto the filter plate, and the filter plate performs a secondary filtration operation on the sewage. During long-term use, a large amount of dirt and impurities are likely to adhere to the upper and lower ends of the filter plate. At this time, by opening the first driving hydraulic cylinder, the driving shaft of the first hydraulic cylinder drives the first cleaning scraper to move leftward along the top of the filter plate. The first cleaning scraper scrapes off the dirt attached to the top of the filter plate, and the scraped dirt is limited by the dirt retaining plate to prevent the dirt from detaching from the first cleaning scraper. Subsequently, under the leftward movement of the first cleaning scraper, the dirt will be pushed into the collection groove on one side of the pull-out plate for centralized collection. When the dirt inside the collection groove needs to be cleaned, the pull-out plate can be pulled out from the inside of the pull-out groove, facilitating the user to clean the inside of the pull-out groove. At the same time, when the dirt attached to the bottom of the filter plate needs to be cleaned, by opening the second driving hydraulic cylinder, the driving shaft of the second hydraulic cylinder drives the second cleaning scraper to move leftward along the bottom of the filter plate. The second cleaning scraper scrapes off the dirt attached to the bottom of the filter plate, and the scraped dirt will fall into the dirt storage bin at the bottom of the second cleaning scraper. The dirt storage bin centrally collects the scraped dirt, thus facilitating the cleaning of the upper and lower ends of the filter plate and preventing the filter plate from being blocked during long-term use, which affects the sewage treatment efficiency.

[0038] The present invention provides as Figures 1-12An integrated sewage treatment device shown in the figure includes a sewage treatment device main body 1. One side of the top end of the sewage treatment device main body 1 is equipped with a water inlet pipe 2. The top end of the water inlet pipe 2 is equipped with a water inlet valve 3. The top end of the sewage treatment device main body 1 is equipped with a cover plate 4. A transmission and filtration mechanism 5 is installed inside the sewage treatment device main body 1. The bottom end of the water inlet pipe 2 is equipped with a conveyor belt 503. A cleaning mechanism 6 is installed inside the conveyor belt 503. A cleaning pipe 601 is inserted into the conveyor belt 503. The top end of the cleaning pipe 601 is equipped with a high-pressure nozzle 603. The bottom end of the cleaning pipe 601 is equipped with a collection plate 606. The bottom end of the conveyor belt 503 is equipped with a repeated filtration mechanism 7. A water guide inclined plate 8 is arranged at the bottom end of the repeated filtration mechanism 7. One end of the bottom of the sewage treatment device main body 1 close to the water inlet pipe 2 is equipped with a water outlet pipe 9. The top end of the water outlet pipe 9 is equipped with a water outlet valve 10. One end of the sewage treatment device main body 1 far from the water outlet pipe 9 is equipped with a second driving hydraulic cylinder 709. One end of the second driving hydraulic cylinder 709 is equipped with a second hydraulic cylinder driving shaft 710. One end of the second hydraulic cylinder driving shaft 710 is equipped with a second cleaning scraper 711. When the present invention is in use, first connect the sewage pipe with the water inlet pipe 2, and then open the water inlet valve 3 to discharge the sewage through the water inlet pipe 2 into the interior of the sewage treatment device main body 1. At this time, by turning on the driving motor 501, the driving roller 502 rotates. The outer wall of the driving roller 502 meshes with the inner wall of the conveyor belt 503. Therefore, when the driving roller 502 rotates, it drives the conveyor belt 503 to perform a conveying operation. The sewage with dirt will fall into the conveyor belt 503 after passing through the water inlet pipe 2. The large particle dirt impurities are blocked at the top end of the conveyor belt 503 through the filter through holes 504 on the conveyor belt 503. The large particle dirt impurities are conveyed to the collection bin 506 through the conveyor belt 503, and then the large particle dirt impurities are conveyed into the interior of the collection bin 506 and collected centrally through the collection bin 506. When it is necessary to clean the dirt inside the collection bin 506, the collection bin 506 can be taken out from the installation groove 509 for cleaning operations, so as to complete the first large particle dirt filtration treatment operation of the sewage. When it is necessary to clean the blockage of the filter through holes 504 on the conveyor belt 503, first connect one end of the cleaning pipe 601 with the water extraction pipe. During the cleaning operation, the cleaning valve 602 can be opened to make the cleaning water enter the cleaning pipe 601 through the water extraction pipe, and then be sprayed out through multiple groups of high-pressure nozzles 603 at the top end of the cleaning pipe 601. Through the spraying of the high-pressure nozzles 603, the blockage in the filter through holes 504 on the conveyor belt 503 is washed away, so as to clean the dirt blocked in the filter through holes 504. At the same time, before the cleaning operation, the limit slider 607 on the collection plate 606 can be inserted into the limit sliding groove 605 at the bottom end of the cleaning pipe 601, and then the collection plate 606 is inserted and installed inside the conveyor belt 503. When flushing the conveyor belt 503,It is also possible to wash the dirt adhering to the inner wall of the conveyor belt 503 at the same time. The collection plate 606 can collect the dirt on the inner wall of the conveyor belt 503 when washing the dirt on the inner wall of the conveyor belt 503, preventing the dirt on the inner wall of the conveyor belt 503 from falling onto the bottom conveyor belt 503 after washing. When it is necessary to clean the dirt on the collection plate 606, the collection plate 606 can be pulled out from the inside of the sewage treatment equipment main body 1 by pulling the pull handle 610 by hand, thus facilitating the cleaning operation of the dirt collected on the collection plate 606. When the sewage is first filtered through the filter through holes 504, it will fall downward onto the filter plate 701, and the filter plate 701 performs a secondary filtering operation on the sewage. During long-term use, a large amount of dirt and impurities are likely to adhere to the upper and lower ends of the filter plate 701. At this time, by opening the first driving hydraulic cylinder 702, the first hydraulic cylinder driving shaft 703 drives the first cleaning scraper 704 to move leftward along the top of the filter plate 701. The first cleaning scraper 704 scrapes off the dirt adhering to the top of the filter plate 701, and the scraped dirt is limited by the dirt retaining plate 705 to prevent the dirt from detaching from the first cleaning scraper 704. Subsequently, under the leftward movement of the first cleaning scraper 704, the dirt is pushed into the collection groove 707 on one side of the pull-out plate 706 for centralized collection. When it is necessary to clean the dirt inside the collection groove 707, the pull-out plate 706 can be pulled out from the inside of the pull-out groove 715, which is convenient for the user to clean the inside of the pull-out groove 715. At the same time, when it is necessary to clean the dirt adhering to the bottom of the filter plate 701, by opening the second driving hydraulic cylinder 709, the second hydraulic cylinder driving shaft 710 drives the second cleaning scraper 711 to move leftward along the bottom of the filter plate 701. The second cleaning scraper 711 scrapes off the dirt adhering to the bottom of the filter plate 701, and the scraped dirt falls into the sewage storage bin 712 at the bottom of the second cleaning scraper 711, and the sewage storage bin 712 centrally collects the scraped dirt, thus facilitating the cleaning of the upper and lower ends of the filter plate 701 and preventing the filter plate 701 from being blocked during long-term use, which affects the sewage treatment efficiency. The sewage secondarily filtered by the filter plate 701 will fall to the bottom of the sewage treatment equipment main body 1. When it is necessary to discharge the filtered sewage, by opening the water outlet valve 10, the filtered sewage can be discharged through the water outlet pipe 9. The water guide inclined plate 8 can guide the sewage to the water outlet pipe 9, which can reduce the accumulated water inside the sewage treatment equipment main body 1.,

[0039] This solution filters large particulate dirt in the sewage through the conveyor filtering mechanism 5. The conveyor filtering mechanism 5 includes a driving motor 501 installed at one end of the main body 1 of the sewage treatment equipment. One end of the driving motor 501 is equipped with a driving roller 502. The end of the conveyor belt 503 away from the driving roller 502 meshes with a driven roller 505. Filter through-holes 504 are formed on the surface of the conveyor belt 503. An installation groove 509 is formed at one end of the main body 1 of the sewage treatment equipment close to the second driving hydraulic cylinder 709. A collection bin 506 is installed inside the installation groove 509. A first filter hole 507 is formed at the bottom of the collection bin 506. A guiding frame 508 supports the bottom end of the collection bin 506. Two groups of guiding frames 508 are installed, and the two groups of guiding frames 508 are respectively installed on both sides of the bottom end of the collection bin 506 to support and limit the movement of the collection bin 506 through the two groups of guiding frames 508. First, connect the sewage pipe to the water inlet pipe 2, and then open the water inlet valve 3 to discharge the sewage through the water inlet pipe 2 into the interior of the main body 1 of the sewage treatment equipment. At this time, turn on the driving motor 501 to make the driving roller 502 rotate. The outer wall of the driving roller 502 meshes with the inner wall of the conveyor belt 503. Therefore, when the driving roller 502 rotates, it will drive the conveyor belt 503 to perform a conveying operation. The sewage with dirt will fall into the conveyor belt 503 after passing through the water inlet pipe 2. The large particulate dirt impurities are blocked at the top of the conveyor belt 503 through the filter through-holes 504 on the conveyor belt 503. The large particulate dirt impurities are conveyed to the collection bin 506 through the conveying of the conveyor belt 503, and then the large particulate dirt impurities will be conveyed into the interior of the collection bin 506 and collected centrally through the collection bin 506. When it is necessary to clean the dirt inside the collection bin 506, the collection bin 506 can be taken out from the installation groove 509 for cleaning operations, thus completing the first-stage large particulate dirt filtering treatment operation of the sewage.

[0040] In this solution, when the filter through-holes 504 on the conveyor belt 503 are blocked and need to be cleaned, the cleaning mechanism 6 can perform a cleaning operation on the blockage of the filter through-holes 504 on the conveyor belt 503. The cleaning mechanism 6 includes a cleaning valve 602 installed at one end of a cleaning pipe 601. At the end of the cleaning pipe 601 away from the cleaning valve 602, a mounting block 604 is fixed. The end of the cleaning pipe 601 away from the cleaning valve 602 is fixedly installed inside the main body 1 of the sewage treatment equipment through the mounting block 604. A limiting chute 605 is opened at the bottom end of the cleaning pipe 601. A limiting slider 607 is installed at the top end of the collection plate 606. The limiting slider 607 slides inside the limiting chute 605. The limiting slider 607 is fixed to the top end of the collection plate 606, and the limiting slider 607 slides inside the limiting chute 605 to limit the installation of the collection plate 606. A second filter hole 608 is opened at the top end of the collection plate 606. Mounting plates 609 are installed at both ends of the collection plate 606. A pull handle 610 is installed at one end of the mounting plate 609. When it is necessary to clean the blockage of the filter through-holes 504 on the conveyor belt 503, first, one end of the cleaning pipe 601 can be connected to a water suction pipe. During the cleaning operation, the cleaning valve 602 can be opened to allow the cleaning water to enter the cleaning pipe 601 through the water suction pipe, and then it is sprayed out through multiple high-pressure nozzles 603 at the top end of the cleaning pipe 601. Through the spraying of the high-pressure nozzles 603, the blockage in the filter through-holes 504 on the conveyor belt 503 is flushed, so as to clean the dirt blocked in the filter through-holes 504. At the same time, before the cleaning operation, the limiting slider 607 on the collection plate 606 can be inserted into the limiting chute 605 at the bottom end of the cleaning pipe 601, and then the collection plate 606 is inserted and installed inside the conveyor belt 503. When flushing the conveyor belt 503, the dirt attached to the inner wall of the conveyor belt 503 can also be flushed at the same time. The collection plate 606 can collect the dirt on the inner wall of the conveyor belt 503 when flushing the dirt on the inner wall of the conveyor belt 503, preventing the dirt on the inner wall of the conveyor belt 503 from falling onto the bottom conveyor belt 503 after flushing. When it is necessary to clean the dirt on the collection plate 606, the collection plate 606 can be pulled out of the main body 1 of the sewage treatment equipment by pulling the pull handle 610, so as to facilitate the cleaning operation of the dirt collected on the collection plate 606.

[0041] After the first filtration operation on the sewage, the sewage after the first filtration will fall onto the repetitive filtration mechanism 7 at the bottom. The repetitive filtration mechanism 7 performs a secondary filtration operation on the sewage. The repetitive filtration mechanism 7 includes a filter plate 701 installed at the bottom end of the conveyor belt 503. The top end of the second driving hydraulic cylinder 709 is installed with a first driving hydraulic cylinder 702. One end of the first driving hydraulic cylinder 702 is installed with a first hydraulic cylinder drive shaft 703. One end of the first hydraulic cylinder drive shaft 703 is installed with a first cleaning scraper 704. The top end of the first cleaning scraper 704 is installed with a dirt retaining plate 705. One end of the filter plate 701 away from the first cleaning scraper 704 is installed with a draw-out plate 706. A collection groove 707 is opened at one end of the draw-out plate 706. A third filtration hole 708 is opened inside the collection groove 707. The bottom end of the second cleaning scraper 711 is installed with a dirt storage bin 712. A fourth filtration hole 713 is opened inside the dirt storage bin 712. The dirt storage bin 712 stores the dirt scraped by the second cleaning scraper 711. A limit plate 714 is provided at the bottom end of the dirt storage bin 712. A draw-out groove 715 is opened at one end of the sewage treatment equipment main body 1 close to the water outlet pipe 9. When the sewage passes through the filtration through-hole 504 for the first filtration, it will fall downward onto the filter plate 701. The filter plate 701 performs a secondary filtration operation on the sewage. During long-term use, a large amount of dirt and impurities are likely to adhere to the upper and lower ends of the filter plate 701. At this time, the first driving hydraulic cylinder 702 can be opened, so that the first hydraulic cylinder drive shaft 703 drives the first cleaning scraper 704 to move leftward along the top end of the filter plate 701. The dirt adhering to the top end of the filter plate 701 is scraped off by the first cleaning scraper 704. The scraped dirt is limited by the dirt retaining plate 705 to prevent the dirt from detaching from the first cleaning scraper 704. Subsequently, under the leftward movement of the first cleaning scraper 704, the dirt will be pushed into the collection groove 707 on one side of the draw-out plate 706 for centralized collection. When it is necessary to clean the dirt inside the collection groove 707, the draw-out plate 706 can be drawn out inside the draw-out groove 715, which is convenient for the user to clean the inside of the draw-out groove 715. At the same time, when it is necessary to clean the dirt adhering to the bottom end of the filter plate 701, the second driving hydraulic cylinder 709 can be opened, so that the second hydraulic cylinder drive shaft 710 drives the second cleaning scraper 711 to move leftward along the bottom end of the filter plate 701. The dirt adhering to the bottom end of the filter plate 701 is scraped off by the second cleaning scraper 711. The scraped dirt will fall into the dirt storage bin 712 at the bottom end of the second cleaning scraper 711. The dirt storage bin 712 centrally collects the scraped dirt, so as to facilitate the cleaning of the upper and lower ends of the filter plate 701 and avoid blockage of the filter plate 701 during long-term use, which affects the sewage treatment efficiency.
