Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a filterable rainwater and sewage separation system. Background Technology

[0002] Separate stormwater and sewage systems refer to an urban drainage model that separates and treats stormwater from domestic sewage and industrial wastewater through the construction of two independent pipe networks. Traditional combined sewer systems are prone to sewage overflows during the rainy season, causing water pollution and urban flooding. Separate systems, by directly discharging stormwater into natural water bodies and centrally treating sewage, effectively improve sewage treatment efficiency and reduce pollutant emissions. This project requires the construction of new stormwater pipe networks, the renovation of old pipes, and the establishment of a long-term management mechanism. In recent years, many Chinese cities have incorporated this approach into their ecological construction plans, significantly improving urban water quality, alleviating the load on sewage treatment plants, and enhancing flood control and drainage capabilities through phased renovations. This provides crucial support for achieving water resource recycling and sustainable development.

[0003] When it rains, rainwater pipes collect rainwater and discharge it. Usually, a filtration system is installed inside the sewage well to filter out larger impurities such as plastic and fallen leaves in the rainwater. However, as impurities such as plastic and fallen leaves accumulate inside the filtration system, the filter pores become clogged, reducing the drainage capacity and thus affecting the filtration efficiency. To address this, we propose a filterable rainwater and sewage separation system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a filterable rainwater and sewage separation system. By collecting and separating most of the fallen leaves and plastic bags inside the filter box, the filter box can be self-cleaned, ensuring filtration efficiency and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filterable rainwater and sewage separation system, comprising a frame, a collection mechanism, and a separation mechanism;

The lower end of the cable of the roller is fixedly connected to the upper end of the vertically adjacent connecting seat respectively.

[0008] Separation mechanism: It includes a separation component and a slide. Slides are provided on both the left and right side walls of the mounting base. A separation component is provided between the two slides. The separation component is configured in conjunction with the filter screen. By collecting and separating most of the fallen leaves and plastic bags inside the filter box, the filter box is self-cleaned, ensuring filtration efficiency.

[0009] Furthermore, it also includes a controller, which is located at the top of the frame and whose input is electrically connected to an external power source to control electrical appliances.

[0010] Furthermore, the collection mechanism includes a connecting shaft and a motor.

The left and right ends of the connecting shaft are respectively fixedly connected to the rotating shaft of the adjacent drum. The input end of the motor is electrically connected to the output end of the controller to realize the rising of the filter screen.

[0011] Furthermore, the separation assembly includes a slide table, spring plates, a shovel plate, a limiting plate, and two sliding columns. The slide table has limiting plates at both ends. Two sliding columns are symmetrically distributed on opposite outer sides of the two limiting plates. Two sliding columns located on the same limiting plate are slidably connected to the interior of adjacent slide grooves. The opposite outer sides of the two limiting plates are slidably connected to the adjacent inner walls of the mounting base. A shovel plate is rotatably connected to the lower end of the slide table. A uniformly distributed spring plate is fixedly connected between the front side of the shovel plate and the lower surface of the slide table. The spring plates are configured to cooperate with the filter screen to separate impurities such as fallen leaves and plastic.

[0012] Furthermore, the separation mechanism also includes an electric push rod, a connecting plate, and a sliding column.

The input end of the electric push rod is electrically connected to the output end of the controller to realize the reciprocating motion of the shovel plate.

[0013] Furthermore, the separation mechanism also includes a limiting rod, which is fixedly connected to the rear end of the mounting base. The limiting rod is located at the rear end of the shovel plate, so that the shovel plate remains tilted.

[0014] Furthermore, it also includes two side collection ramps. Each of the two side collection ramps has a uniformly distributed sliding column three fixedly connected to its opposite outer side.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This embodiment provides a technical solution: a filterable rainwater and sewage separation system, including a frame 1, a collection mechanism 4 and a separation mechanism 6;

[0027] Frame 1: A filter box 2 is installed at its upper end. A mounting base 10 is fixedly connected to the upper end of the filter box 2. A collection box 11 is placed at the upper front side of the frame 1. A filter plate 3 is fixedly connected to the lower front side of the filter box 2 (the filter plate 3 can be installed at the lower front side of the filter box 2 by external bolts). When the filter screen 45 is reset, the fallen leaves and plastic remaining on the inner wall of the filter box 2 are scraped to the bottom wall of the filter box 2. The scraper plate 613 moves back and forth repeatedly, so that most of the plastic and fallen leaves are scraped to the collection box 11. The bottom wall of the collection box 11 has evenly distributed filter holes, so that the water adhering to the plastic and fallen leaf surfaces inside the collection box 11 can be slowly drained, reducing the weight of the collection box 11 and making it easier to remove during cleaning. During cleaning, the filter plate 3 is opened to clean the fallen leaves and plastic remaining on the bottom wall of the filter box 2.

[0028] Collection mechanism 4 includes a roller 42, an inclined platform 44, and a filter screen 45. The filter screen 45 is placed on the bottom wall of the filter box 2. The inclined platform 44 is fixedly connected to the upper edge of the filter screen 45. The filter screen 45 and the inclined platform 44 are slidably connected to the inner wall of the filter box 2. When the filter screen 45 is reset, the fallen leaves and plastic remaining on the inner wall of the filter box 2 are scraped to the bottom wall of the filter box 2. The left and right ends of the filter screen 45 are provided with connecting seats 5. The upper end of the mounting base 10 is provided with rollers 42 symmetrically distributed on the left and right. The lower ends of the cables of the rollers 42 are fixedly connected to the upper ends of the vertically adjacent connecting seats 5 respectively. The collection mechanism 4 includes a connecting shaft 41 and a motor 43. The motor 43 is fixedly connected to the upper surface of the mounting base 10. The output shaft of the motor 43 is internally connected to the motor. A connecting shaft 41 is fixedly connected, and the left and right ends of the connecting shaft 41 are respectively fixedly connected to the rotating shaft of the adjacent drum 42. The input end of the motor 43 is electrically connected to the output end of the controller 12. The output shaft of the motor 43 drives the two drums 42 to rotate synchronously through the connecting shaft 41 to retract the cable. The filter screen 45 and the inclined platform 44 slide and rise inside the filter box 2. The inclined platform 44 increases the contact area with the inner wall of the filter box 2 to prevent the filter screen 45 from deflecting during the lifting process. At the same time, the inclined platform 44 scrapes off the plastic bags and fallen leaves and other impurities that are stuck to the inner wall of the filter box 2. The scraped plastic bags and fallen leaves and other impurities slide down to the upper end of the filter screen 45. The filter screen distance of the filter screen 45 is controlled by controlling the start time of the motor 43.

[0029] Separation mechanism 6: It includes a separation component 61 and a slide 64. Slides 64 are provided on both the left and right side walls of the mounting base 10. The separation component 61 is positioned between the two slides 64 and cooperates with the filter screen 45. The separation component 61 includes a slide table 611, a spring plate 612, a shovel plate 613, a limiting plate 614, and two sliding columns 615. Limiting plates 614 are provided at both ends of the slide table 611. Two sliding columns 615 are symmetrically distributed on opposite outer surfaces of the two limiting plates 614. Two sliding columns 615 located on the same limiting plate 614 are slidably connected to the interior of adjacent slides 64. The slide table 611 is rotatably connected to the inner wall adjacent to the mounting base 10. A shovel plate 613 is rotatably connected to the lower end of the slide table 611. A uniformly distributed spring plate 612 is fixedly connected between the front side of the shovel plate 613 and the lower surface of the slide table 611. The spring plate 612 is configured to cooperate with the filter screen 45. The separation mechanism 6 also includes an electric push rod 62, a connecting plate 63, and a sliding column 66. A sliding column 66 is fixedly connected to the upper surface of the slide table 611. The front ends of the sliding columns 66 are slidably connected to the interior of adjacent through holes on the front side of the mounting base 10. A connecting plate 63 is fixedly connected between the front ends of two sliding columns 66. An electric push rod 62 is fixedly connected to the upper surface of the mounting base 10. The extension of the electric push rod 62... The retractable end is fixedly connected to the rear side of the connecting plate 63. The input end of the electric push rod 62 is electrically connected to the output end of the controller 12. The separation mechanism 6 also includes a limit rod 65. The rear end of the mounting base 10 is fixedly connected to the limit rod 65. The limit rod 65 is located at the rear end of the shovel plate 613. The shovel plate 613 is kept tilted forward due to the limit of the limit rod 65. When the inclined platform 44 rises, the shovel plate 613 scrapes off plastic bags and fallen leaves from the rear side of the inclined platform 44. When the inclined platform 44 rises to the highest point, the retractable end of the electric push rod 62 is pushed out, the connecting plate 63 is pushed forward, the first slide column 66 slides forward, pulling the slide platform 611 and the shovel plate 613 forward. The two slide columns 615 located on the same limit plate 614... The two limiting plates 614 are slidably connected to the interior of adjacent slide grooves 64 respectively. The opposite outer sides of the two limiting plates 614 are slidably connected to the adjacent inner walls of the mounting base 10, making the displacement of the slide table 611 more stable. The spring plate 612 presses down on the shovel plate 613 due to the elastic potential energy, so that the lower end of the shovel plate 613 slides on the upper surface of the filter screen 45. When the shovel plate 613 moves to the front end of the inclined platform 44, it slides along the inclined surface of the front end of the inclined platform 44. After leaving the inclined platform 44, the shovel plate 613 reverses downward due to the elastic potential energy of the spring plate 612. The hung plastic and fallen leaves fall into the interior of the collection box 11. The shovel plate 613 reciprocates repeatedly, so that most of the plastic and fallen leaves are scraped into the collection box 11.

[0030] It also includes a controller 12, which is located at the top of the frame 1 and whose input is electrically connected to an external power source.

[0031] The system includes two side collection ramps 7. Each side collection ramp 7 has two opposite outer sides with evenly distributed sliding columns 8 fixedly connected to it. The sliding columns 8 on the same side collection ramp 7 are slidably connected to the round holes on the left and right side walls of the mounting base 10. Springs 9 are movably fitted onto the outside of each sliding column 8. The springs 9 are located between the end of the sliding column 8 furthest from the mounting base 10 and the adjacent side of the mounting base 10. The side collection ramp 7 moves towards the center of the mounting base 10 under the thrust of the ramp 44. The sliding columns 8 slide inside the round holes on the left and right side walls of the mounting base 10, compressing the springs 9. Due to their elastic potential energy, the springs 9 generate a reaction force, causing the lower surface of the side collection ramp 7 to tightly adhere to the left and right sides of the ramp 44. The ramp 44 gradually rises to its highest point, and plastic bags and fallen leaves on the left and right sides of the ramp 44 are scraped onto the upper surface of the filter screen 45.

[0032] The working principle of the filterable rainwater and sewage separation system provided by this utility model is as follows: The frame 1 is fixed inside the sewage well, and the rear side of the filter box 2 is connected to the rainwater pipe. The controller 12 has a wireless module inside, and the sewage system platform can send control commands through the Internet of Things. When it rains, the rainwater collected by the rainwater pipe enters the filter box 2. Larger impurities such as plastic bags and fallen leaves are intercepted inside the filter box 2, while impurities such as mud and sand are discharged with the rainwater. When the rain stops, the rainwater pipe stops flowing out, and the controller 12 starts the motor 43. The output shaft of the motor 43 drives two drums 42 to rotate synchronously through the connecting shaft 41, retracting the cable. The filter screen 45 and the inclined platform 44 slide and rise inside the filter box 2. The inclined platform 44 increases the filtration efficiency. The contact area of ​​the inner wall of the filter box 2 is increased to prevent the filter screen 45 from deflecting during the lifting process. At the same time, the inclined platform 44 scrapes off the plastic bags, fallen leaves and other impurities adhering to the inner wall of the filter box 2. The scraped plastic bags, fallen leaves and other impurities slide down to the upper end of the filter screen 45. The filter screen 45 is controlled by controlling the start time of the motor 43. The filter screen 45 and the inclined platform 44 rise as a whole. The left and right sides of the inclined platform 44 respectively fit with the lower surface of the vertically adjacent side collection inclined platform 7. As it continues to rise, the side collection inclined platform 7 moves towards the middle of the mounting base 10 under the push of the inclined platform 44. The sliding column 8 slides inside the round holes on the left and right side walls of the mounting base 10 respectively. The springs 9 are all compressed. The springs 9 generate a reaction force due to the elastic potential energy, causing the lower side collection inclined platform 7 to move. The surface is tightly attached to the left and right sides of the inclined platform 44. The inclined platform 44 gradually rises to its highest point. Plastic bags and fallen leaves on the left and right sides of the inclined platform 44 are scraped onto the upper surface of the filter screen 45. At the same time, the shovel plate 613 is kept tilted forward due to the limiting rod 65. When the inclined platform 44 rises, the shovel plate 613 scrapes off the plastic bags and fallen leaves on the rear side of the inclined platform 44. When the inclined platform 44 rises to its highest point, the telescopic end of the electric push rod 62 is pushed out, the connecting plate 63 is pushed forward, and the first sliding column 66 slides forward, pulling the sliding platform 611 and the shovel plate 613 forward. The two second sliding columns 615 located on the same limiting plate 614 are slidably connected to the interior of the adjacent sliding groove 64. The opposite outer sides of the two limiting plates 614 are slidably connected to the... The adjacent inner walls of the mounting base 10 make the displacement of the slide table 611 more stable. The spring plate 612, due to its elastic potential energy, presses down on the scraper plate 613, causing the lower end of the scraper plate 613 to slide on the upper surface of the filter screen 45. When the scraper plate 613 moves to the front end of the inclined platform 44, it slides along the inclined surface of the platform. After leaving the inclined platform 44, due to the elastic potential energy of the spring plate 612, the scraper plate 613 reverses downwards, causing the hung plastic and fallen leaves to fall into the collection box 11. The scraper plate 613 reciprocates repeatedly, scraping most of the plastic and fallen leaves into the collection box 11. The bottom wall of the collection box 11 has evenly distributed filter holes, allowing the water adhering to the surface of the plastic and fallen leaves inside the collection box 11 to slowly drain, reducing the weight of the collection box 11 and making it easier to remove during cleaning.When filter screen 45 is reset, the fallen leaves and plastic residue remaining on the inner wall of filter box 2 are scraped to the bottom wall of filter box 2. During cleaning, filter plate 3 is opened to clean the remaining fallen leaves and plastic residue from the bottom wall of filter box 2.

[0033] It is worth noting that the controller 12 disclosed in the above embodiments can be an S7-200CN, the motor 43 can be an S57-Y0.75KW-M1-270 double-output shaft worm gear reducer, and the electric actuator 62 can be a DT series electric actuator. The controller 12 controls the operation of the motor 43 and the electric actuator 62 using methods commonly used in the prior art.
