[0018] This invention provides a scum collection device for wastewater treatment. It has the following beneficial effects:

[0019] 1. This wastewater treatment scum collection equipment, through the installation of a positioning mechanism, a scum removal mechanism, and an edge scraping mechanism, addresses the issue of scum mixing with wastewater after being scooped up by a screen during the scum removal and collection process. As the screen moves and the collection continues, wastewater enters the collection equipment along with the scum, requiring subsequent dewatering. Therefore, the positioning, scum removal, and edge scraping mechanisms are installed to scrape the edges of the wastewater tank. An air flotation system then lifts the scum to the surface. After the scum removal process is completed, air is supplied to the scum to promote the downward flow of wastewater into the wastewater tank, thus resolving the aforementioned problems. This achieves the goal of facilitating the removal of scum from the surface of the wastewater tank.

[0020] 2. This scum collection equipment for wastewater treatment, by incorporating a positioning mechanism, controls the specific position of the equipment during the scraping and scum removal processes. This coordinates with the scraping and scum removal work, and after the scum removal is completed, air is supplied to promote the separation of wastewater and scum. This achieves the purpose of facilitating equipment position control and providing air for the scum removal process.

[0021] 3. This wastewater treatment scum collection equipment uses a scum removal mechanism to remove scum from the surface of the wastewater. During the scum removal and collection process, after the scum is scooped up by a screen, it mixes with the wastewater. As the screen moves and the collection process continues, the wastewater enters the collection equipment along with it, requiring subsequent dewatering. Therefore, the scum removal mechanism is installed to remove scum from the wastewater surface. Furthermore, with the assistance of a positioning mechanism, air can be supplied to the scum, promoting the return of wastewater within the scum to the bottom wastewater tank, thus solving the aforementioned problems. This achieves the goal of facilitating scum removal and promoting the separation of scum from wastewater.

[0022] 4. The scum collection equipment for this wastewater treatment system, through the installation of a scraping mechanism, allows suspended solids to rise to the surface of the wastewater tank during the use of the air flotation system. This forms a stable scum layer that is difficult to disperse and settle. As the water level changes, some scum adheres to the corners of the wastewater tank, making it difficult to remove scum from these areas. Therefore, the scraping mechanism scrapes the scum from the corners of the wastewater tank off the inner wall before the air flotation system is used, reducing the amount of scum adhering to the inner wall. This achieves the goal of facilitating the removal of scum from the corners of the wastewater tank. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] like Figures 1-8 As shown, the present invention provides a technical solution, specifically including:

[0034] Fixed box 1, with telescopic curved rod 3 fixedly connected to the bottom of fixed box 1, slide rail 5 opened inside fixed box 1, and positioning mechanism 2 fixedly connected to the outside of fixed box 1;

[0035] The scum collection equipment for this wastewater treatment also includes:

[0036] The slag removal mechanism 4 is used to remove slag from the upper surface of the sewage tank. The slag removal mechanism 4 is fixedly connected to the bottom of the telescopic bending rod 3. The slag removal mechanism 4 includes a fixed frame 401. A first inclined plate 402 is fixedly connected to the bottom of the fixed frame 401. A second inclined plate 403 is rotatably connected to the bottom of the first inclined plate 402. The fixed frame 401 is fixedly connected to the outside of the telescopic bending rod 3.

[0037] The scraping mechanism 6 is used to move the scum at the corner of the sewage tank. The scraping mechanism 6 is slidably connected inside the slide rail 5. The scraping mechanism 6 includes a sliding plate 601. An adjusting rod 603 is fixedly connected to the outside of the sliding plate 601. A motor box 604 is fixedly connected to the outside of the adjusting rod 603. The sliding plate 601 is slidably connected inside the slide rail 5.

[0038] Before using the equipment, activate the positioning mechanism to move the equipment to the sewage tank. Activate positioning mechanism 2 and scraping mechanism 6 to scrape the right-angled edges of the sewage tank. Then, activate the air flotation system in the sewage tank to move the scum to the surface of the sewage. Subsequently, activate positioning mechanism 2 and scum removal mechanism 4 to remove the scum.

[0039] Both the first inclined plate 402 and the second inclined plate 403 have flow holes inside. The first inclined plate 402 is fixedly connected to the outside of an elastic plate 407, and there are two elastic plates 407.

[0040] The bottom of the fixed frame 401 is fixedly connected to a fourth telescopic rod 404, and the bottom of the fourth telescopic rod 404 is fixedly connected to an elastic joint 405. During the opening or closing of the fourth telescopic rod 404, the elastic joint 405 undergoes corresponding deformation. The elastic joint 405 is fixedly connected to the top of the second inclined plate 403, and the outside of the second inclined plate 403 is fixedly connected to a support rod 406.

[0041] In the initial state, the fourth telescopic rod 404 is in the closed state. At this time, the angle between the first inclined plate 402 and the second inclined plate 403 is small, and the fourth telescopic rod 404 is set to have two strokes.

[0042] Before starting the slag removal operation, manually adjust the length of the horizontal bar portion of the telescopic bending rod 3 so that the second inclined plate 403 is at the bottom of the positioning assembly. Open the fourth telescopic rod 404 to its second stroke. At this time, the fourth telescopic rod 404 drives the elastic joint 405 to move downward, which in turn drives the second inclined plate 403 to rotate downward, increasing the angle between the second inclined plate 403 and the first inclined plate 402 until the second inclined plate 403 is in a downward tilted state. Then open the telescopic bending rod 3, which drives the fixed frame 401 to move downward, which in turn drives the entire slag removal mechanism 4 to move downward. Close the fourth telescopic rod 404 to its first stroke. The fourth telescopic rod 404 drives the elastic joint 405 and the second inclined plate 403 to rotate upward, reducing the angle between the second inclined plate 403 and the first inclined plate 402 until the second inclined plate 403 and the support rod 406 gradually become horizontal. Activate the positioning mechanism 2, which begins to drive the entire equipment forward. At this time, the scum on the surface of the sewage gradually enters the second inclined plate 403.

[0043] After the slag removal is completed, the fourth telescopic rod 404, which was in the open state, is closed. The fourth telescopic rod 404 drives the second inclined plate 403 back to its original position. At this time, the angle between the second inclined plate 403 and the first inclined plate 402 is small. The telescopic curved rod 3, which was in the open state, is closed. The telescopic curved rod 3 drives the entire slag removal mechanism 4 to move upward. This promotes the downward flow of sewage mixed in the slag through the flow holes. At the same time, the positioning mechanism 2 is activated to supply air to the second inclined plate 403 and the first inclined plate 402, promoting the flow of sewage.

[0044] An electric push rod 602 is fixedly connected inside the slide rail 5. The electric push rod 602 is fixedly connected to the sliding plate 601. A motor is fixedly connected inside the motor box 604. A first telescopic rod 605 is fixedly connected to the output end of the motor. When it is necessary to adjust the scraping angle, the motor is turned on. The motor drives the first telescopic rod 605 to rotate, which in turn drives the bottom equipment to rotate, thereby adjusting the scraping angle.

[0045] A second spring 606 is fixedly connected to the bottom of the motor housing 604. A lifting frame 607 is fixedly connected to the bottom of the second spring 606. A fixed scraper 608 is fixedly connected inside the lifting frame 607. Multiple fixed scrapers 608 are provided. The lifting frame 607 is slidably connected to the outside of the first telescopic rod 605. When the first telescopic rod 605 is in the closed state, the scraper 610 is in the lifting frame 607, and the arc plate 611 is in contact with the fixed scraper 608.

[0046] A circular plate 609 is fixedly connected to the bottom of the first telescopic rod 605. A scraper 610 is fixedly connected to the bottom of the circular plate 609. An arc-shaped plate 611 is fixedly connected to the outside of the scraper 610. There are two arc-shaped plates 611. A circular hole 612 is opened inside the scraper 610. There are multiple circular holes 612. A lightweight plate 613 is fixedly connected to the bottom of the circular plate 609. An adhesive rod 614 is fixedly connected to the outside of the lightweight plate 613.

[0047] According to the position of the corner of the sewage tank, adjust the stroke of the electric push rod 602, and open one side of the electric push rod 602. The electric push rod 602 drives the sliding plate 601 to move inside the slide rail 5. At the same time, the first telescopic rod 605 is opened. The first telescopic rod 605 drives the circular plate 609 and the scraper 610 to move downward until the scraper 610 is attached to the inner wall of the sewage tank. The scraper 610 is partially submerged in water and partially above water. The arc plate 611 contacts the inner wall of the sewage tank. Then, the electric push rod 602 is opened. The electric push rod 602 drives the sliding plate 601 to move. The sliding plate 601 drives the adjusting rod 603, the motor box 604, the first telescopic rod 605, the circular plate 609 and the scraper 610 to move, scraping the inner wall of the sewage tank.

[0048] If it is necessary to scrape the other side, turn on the motor. The motor drives the first telescopic rod 605, the circular plate 609 and the scraper 610 to rotate, so that the scraper 610 sticks to the other corner. Then, the positioning mechanism 2 is activated to scrape the other side, promoting the scum and debris to detach from the corner. Then, the air flotation system in the sewage tank is activated to make the scum float on the surface of the sewage tank.

[0049] During the scraping process, the lightweight plate 613 and the adhesive rod 614 are always positioned in front of the scraper 610 in the direction of movement to protect the round hole 612 and adhere some of the scum, preventing the round hole 612 from becoming clogged. After use, the first telescopic rod 605, which was in the open state, is closed. The first telescopic rod 605 drives the round plate 609 and the scraper 610 to move upwards, and the arc-shaped plate 611 begins to contact the fixed scraper 608, removing the scum adhering to the outside of the arc-shaped plate 611 by friction. Driven by the arc-shaped plate 611, the lifting frame 607 and the second spring 606 are moved, promoting the downward movement of the scum.

[0050] The positioning mechanism 2 includes a back plate 201, an air supply assembly 202 is fixedly connected to the outside of the back plate 201, a fan is fixedly connected to the inside of the fixed box 1, a connecting plate 203 is fixedly connected to the outside of the fixed box 1, and the back plate 201 is fixedly connected to the top of the fixed box 1.

[0051] The connecting plate 203 is externally fixedly connected to a support frame 204, which contains a power system. The bottom of the support frame 204 is fixedly connected to a vertical rod 205, which has casters at the bottom. The vertical rod 205 is externally fixedly connected to a fixing ring 206, which is externally fixedly connected to a second telescopic rod 207. The second telescopic rod 207 is externally fixedly connected to a fixing frame 208, which is internally fixedly connected to a first spring 209. The first spring 209 is externally fixedly connected to a mounting plate 210, which is externally fixedly connected to a suction cup.

[0052] When scraping the edge of the sewage tank, activate the power system inside the support frame 204. The equipment gradually moves to the edge of the sewage tank until the fixed box 1 is at the edge of the sewage tank. Activate the second telescopic rod 207, which drives the fixed frame 208, the first spring 209, and the mounting plate 210 to move outward until the suction cups on the outside of the mounting plate 210 are attracted and fixed to the outside of the sewage tank. At this point, the equipment position is fixed, and the scraping of the sewage tank can be performed.

[0053] When scraping the other side of the sewage tank, the second telescopic rod 207, which is in the open state, is closed. The second telescopic rod 207 drives the plate 210 back to its original position, and the power system in the support frame 204 is turned on. The equipment begins to move to the other side of the sewage tank to assist in the scraping work.

[0054] The air supply assembly 202 includes a fixed rod 2021, a third telescopic rod 2022 is fixedly connected to the bottom of the fixed rod 2021, a rubber plate 2023 is fixedly connected to the bottom of the third telescopic rod 2022, and the fixed rod 2021 is fixedly connected to the outside of the backing plate 201.

[0055] The air supply assembly 202 also includes a fixed pipe 2024, a rotating pipe 2025 is rotatably connected to the outside of the fixed pipe 2024, a sleeve 2026 is fixedly connected to the outside of the rotating pipe 2025, a moisture-absorbing rod is provided inside the sleeve 2026, the sleeve 2026 is fixedly connected to the rubber plate 2023, and the fixed pipe 2024 is fixedly connected to the outside of the fixed box 1.

[0056] Initially, the third telescopic rod 2022 is closed, and the rotating pipe 2025 is horizontal. After the slag removal operation is completed, the third telescopic rod 2022 is opened, causing the rubber plate 2023 and the rotating pipe 2025 to move downwards until the rotating pipe 2025 is tilted downwards. The blower is then turned on, and the air from the blower enters the rotating pipe 2025 through the fixed pipe 2024, and then moves to the slag removal mechanism 4, supplying air to the slag removal mechanism 4.

[0057] Working Principle: Before using the equipment, activate the positioning mechanism 2 and the scraping mechanism 6 to scrape the right-angled edges of the sewage tank. Then, activate the air flotation system in the sewage tank to move the scum to the surface of the sewage. While scraping the sewage tank, activate the power system within the support frame 204. The equipment gradually moves to the edge of the sewage tank until the fixed box 1 is positioned at the edge. Activate the second telescopic rod 207, which drives the fixed frame 208, the first spring 209, and the mounting plate 210 outwards until the suction cups on the outside of the mounting plate 210 adhere and fix it to the outside of the sewage tank. At this point, the equipment is in a fixed position and the scraping work can begin.

[0058] According to the position of the corner of the sewage tank, adjust the stroke of the electric push rod 602, and open one side of the electric push rod 602. The electric push rod 602 drives the sliding plate 601 to move inside the slide rail 5. At the same time, the first telescopic rod 605 is opened. The first telescopic rod 605 drives the circular plate 609 and the scraper 610 to move downward until the scraper 610 is attached to the inner wall of the sewage tank. The scraper 610 is partially submerged in water and partially above water. The arc plate 611 contacts the inner wall of the sewage tank. Then, the electric push rod 602 is opened. The electric push rod 602 drives the sliding plate 601 to move. The sliding plate 601 drives the adjusting rod 603, the motor box 604, the first telescopic rod 605, the circular plate 609 and the scraper 610 to move, scraping the inner wall of the sewage tank.

[0059] If scraping is required on the other side, the motor is turned on, driving the first telescopic rod 605, the circular plate 609, and the scraper 610 to rotate, causing the scraper 610 to adhere to the other corner. The second telescopic rod 207, which was in the open state, is then closed, causing the plate 210 to return to its original position. The power system within the support frame 204 is then activated, and the equipment begins to move to the other side of the sewage tank to assist in the scraping process. Scraping is then performed on the other side to promote the removal of scum and debris from the corner. Finally, the air flotation system in the sewage tank is activated, causing the scum to float on the surface of the sewage tank.

[0060] During the scraping process, the lightweight plate 613 and the adhesive rod 614 are always positioned in front of the scraper 610 in the direction of movement to protect the round hole 612 and adhere some of the scum, preventing the round hole 612 from becoming clogged. After use, the first telescopic rod 605, which was in the open state, is closed. The first telescopic rod 605 drives the round plate 609 and the scraper 610 to move upwards, and the arc-shaped plate 611 begins to contact the fixed scraper 608, removing the scum adhering to the outside of the arc-shaped plate 611 by friction. Driven by the arc-shaped plate 611, the lifting frame 607 and the second spring 606 are moved, promoting the downward movement of the scum.

[0061] Then, the positioning mechanism 2 and the slag removal mechanism 4 are activated to remove the slag. In the initial state, the fourth telescopic rod 404 is in the closed state. At this time, the angle between the first inclined plate 402 and the second inclined plate 403 is small, and the fourth telescopic rod 404 is set to have two strokes.

[0062] Before starting the slag removal operation, manually adjust the length of the horizontal bar portion of the telescopic bending rod 3 so that the second inclined plate 403 is at the bottom of the positioning assembly. Open the fourth telescopic rod 404 to its second stroke. At this time, the fourth telescopic rod 404 drives the elastic joint 405 to move downward, which in turn drives the second inclined plate 403 to rotate downward, increasing the angle between the second inclined plate 403 and the first inclined plate 402 until the second inclined plate 403 is in a downward tilted state. Then open the telescopic bending rod 3, which drives the fixed frame 401 to move downward, which in turn drives the entire slag removal mechanism 4 to move downward. Close the fourth telescopic rod 404 to its first stroke. The fourth telescopic rod 404 drives the elastic joint 405 and the second inclined plate 403 to rotate upward, reducing the angle between the second inclined plate 403 and the first inclined plate 402 until the second inclined plate 403 and the support rod 406 gradually become horizontal. Activate the positioning mechanism 2, which begins to drive the entire equipment forward. At this time, the scum on the surface of the sewage gradually enters the second inclined plate 403.

[0063] After the slag removal is completed, the fourth telescopic rod 404, which was in the open state, is closed. The fourth telescopic rod 404 drives the second inclined plate 403 back to its original position. At this time, the angle between the second inclined plate 403 and the first inclined plate 402 is small. The telescopic curved rod 3, which was in the open state, is closed. The telescopic curved rod 3 drives the entire slag removal mechanism 4 to move upward. This promotes the downward flow of sewage mixed in the slag through the flow hole. At the same time, the positioning mechanism 2 is activated, and the third telescopic rod 2022 is activated. The third telescopic rod 2022 drives the rubber plate 2023 and the rotating pipe 2025 to move downward until the rotating pipe 2025 is in a downward inclined state. The blower is turned on. The air from the blower enters the rotating pipe 2025 through the fixed pipe 2024 and then moves to the slag removal mechanism 4, supplying air to the second inclined plate 403 and the first inclined plate 402, promoting the flow of sewage.
