Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, specifically to urban wastewater filtration devices. Background Technology

[0002] Before entering the primary sedimentation tank, large debris and impurities in the sewage flow channel need to be separated to prevent them from clogging the sewage flow channel.

[0003] A search revealed an existing patent (publication number: CN119656671A4) that discloses a wastewater filtration device. The wastewater filtration device includes a shell, a filter element, a first transport element, and a second transport element. The shell has two independent cavities: a first cavity for introducing wastewater and a second cavity for storing impurities. The filter element is disposed within the first cavity and is used to filter impurities from the wastewater. The first transport element is disposed within the shell, with its two ends located within the first and second cavities, respectively. The first transport element rotates relative to the second cavity between a first position and a second position about the width of the shell. In the first position, the first transport element is positioned on the filter element so that impurities on the filter element are transported to the second cavity via the first transport element. In the second position, the first transport element and the filter element are spaced apart vertically, and the second transport element is located below and communicates with the second cavity to transport impurities from the second cavity. The wastewater filtration device of this invention has advantages such as simple structure and low cost.

[0004] While the aforementioned devices offer advantages such as simple structure and low cost, their automatic scraper mechanisms lack real-time monitoring capabilities and cannot dynamically adjust the cleaning frequency based on impurity accumulation. Furthermore, direct storage or transportation of large intercepted impurities can easily cause equipment jamming, increasing maintenance costs. Therefore, there is an urgent need for a filtration device with intelligent monitoring, automatic cleaning, and impurity pretreatment to improve wastewater treatment efficiency and automation levels. Summary of the Invention

[0005] 1. Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an urban sewage filtration device, which solves the problems mentioned in the background technology.

[0006] 2. Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A municipal wastewater filtration device includes a housing and a partition. The partition is fixedly connected inside the housing. A filtration chamber is located on the left side of the partition inside the housing, and a crushing chamber is located on the right side of the partition inside the housing. An inlet pipe passes through the left side of the housing and is connected to the filtration chamber. A fixing plate is fixedly connected to the lower end surface of the inlet pipe. An industrial camera is mounted on the side of the fixing plate. A filter screen is installed inside the filtration chamber. The industrial camera is used to capture real-time images of impurity accumulation on the surface of the filter screen. A cleaning mechanism is installed inside the filtration chamber and the crushing chamber. The cleaning mechanism includes a first electric push rod and a second electric push rod. A crushing mechanism is installed inside the crushing chamber. The crushing mechanism includes a first forward and reverse motor. A controller is mounted on the upper surface of the housing. An image processor is installed inside the controller. The controller is electrically connected to the industrial camera, the first electric push rod, the second electric push rod, and the first forward and reverse motor. Through the above technical solution, by setting up an industrial camera, controller, crushing mechanism, and cleaning mechanism, and through the linkage design of the industrial camera and image processor, real-time visual monitoring of the degree of impurity accumulation on the filter screen surface is achieved. The controller can intelligently trigger the cleaning mechanism based on image analysis results, causing the first and second electric push rods to drive the extension, retraction, and angle adjustment of the scraper. This closed-loop control breaks through the traditional mechanical mode of timed cleaning, avoiding energy waste caused by over-cleaning and preventing the decline in filtration efficiency caused by impurity blockage, effectively improving the system's adaptability.

[0007] Furthermore, a motor housing is fixedly connected to the right side of the housing. The first forward and reverse motor is fixedly connected inside the first motor housing. The output end of the first forward and reverse motor is rotatably connected inside the crushing chamber and fixedly connected to a first rotating rod. A first gear is fixedly connected to the surface of the output end of the first forward and reverse motor. A second gear is meshed with the surface of the first gear. Both the first gear and the second gear are rotatably connected inside the motor housing. A second rotating rod is fixedly connected inside the second gear. The right end of the second rotating rod is rotatably connected inside the motor housing. The left ends of both the first rotating rod and the second rotating rod are rotatably connected inside the crushing chamber. A first crushing roller and a second crushing roller are fixedly connected to the surfaces of the first rotating rod and the second rotating rod. Both the first crushing roller and the second crushing roller are rotatably connected inside the crushing chamber. Through the above technical solution, the crushing mechanism drives the first and second gears, which are meshed by the first positive and negative motors, to drive the first crushing roller and the second crushing roller to simultaneously crush the intercepted impurities, crushing large-sized impurities to a particle size that can pass through the conveying mechanism, thus fundamentally solving the problem of impurities blocking the conveying pipeline in the prior art.

[0008] Furthermore, the cleaning mechanism includes a first ball seat and a second ball seat, both of which are fixedly connected inside the crushing chamber. A first rotating ball and a second rotating ball are rotatably connected inside the first and second ball seats. The right end of the first electric push rod is fixedly connected to the surface of the first rotating ball, and the right end of the second electric push rod is fixedly connected to the surface of the second rotating ball. A scraper is fixedly connected to the left end of the first electric push rod. The scraper is in contact with the surface of the filter screen. A through hole is provided in the middle of the partition, and the first electric push rod passes through the through hole. A U-shaped seat is fixedly connected to the lower surface of the first electric push rod, and the upper end of the second electric push rod is movably connected to the inside of the U-shaped seat. With the above technical solution, when the first electric push rod completes one push and the scraper begins to reset, the second electric push rod, under the control of the controller, raises the scraper and the first electric push rod to a certain height, so as to prevent the scraper from pushing impurities to the outer wall of the filter chamber, making it difficult to clean. When the scraper is completely reset, the second electric push rod releases force and the scraper falls back to the position close to the filter screen.

[0009] Furthermore, a water outlet mechanism is provided inside the filter chamber. The water outlet mechanism includes a housing, which is fixedly connected inside the filter chamber. A water outlet pipe is connected to the lower end of the housing, and the lower end of the water outlet pipe extends out of the filter chamber. The water outlet pipe is used to discharge the filtered wastewater. With the above technical solution, the filtered water flows into the water outlet mechanism below, which facilitates the discharge of filtered wastewater.

[0010] Furthermore, a collecting component is provided inside the crushing chamber, with its lower end extending out of the crushing chamber. A conveying mechanism is connected to the lower end of the collecting component. The conveying mechanism includes a conveying shell, with the lower end of the collecting component connected to the conveying shell. A second forward and reverse motor is provided at the left end of the conveying shell, with its output end rotatably connected inside the conveying shell. A third rotating rod is fixedly connected to the output end of the second forward and reverse motor, and a spiral blade is provided on the surface of the third rotating rod. The spiral blade is rotatably connected inside the conveying shell. A drain pipe is connected to the lower surface of the left end of the conveying shell so that the wastewater in the conveying shell can be discharged through the drain pipe. The conveying mechanism is used to transport impurities in the crushing chamber. The conveying shell extends from top to bottom and is inclined toward the direction adjacent to the filter chamber. Through the above technical solution, the crushed impurities fall into the collection device at the bottom of the crushing chamber and enter the inclined conveying shell. The second positive and negative motor drives the spiral blades to rotate, pushing the solid impurities to the right to the designated collection point. At the same time, the sewage is discharged through the drain pipe at the bottom during the conveying process, realizing solid-liquid separation.

[0011] Furthermore, a sealing door is provided on the front side of the housing, which corresponds to the filter screen and the industrial camera, and a support leg is provided at the lower end of the housing; The above technical solution allows for quick inspection or replacement of filters and industrial cameras via the front sealed door, while the support legs at the bottom of the housing provide stable support, preventing vibration from affecting the imaging accuracy of the industrial camera.

[0012] Furthermore, the filter screen extends from top to bottom and is inclined in a direction away from the crushing chamber, and one end of the filter screen adjacent to the crushing chamber is flush with the lower end face of the through hole; Through the above technical solution, the inclined design of the filter screen generates a downward force in the water flow, accelerating the sliding of impurities onto the surface of the filter screen.

[0013] Furthermore, the outer casing is located below the filter screen, and the cross-sectional area of ​​the upper end of the outer casing gradually decreases from top to bottom. Through the above technical solution, the outer shell of the water outlet mechanism adopts a tapering structure that is larger at the top and smaller at the bottom. The change in cross-sectional area creates a confluence and acceleration, and the sewage is quickly discharged through the outlet pipe.

[0014] 3. Beneficial effects This invention provides a municipal wastewater filtration device. It has the following beneficial effects: 1. This invention provides an urban sewage filtration device. By incorporating an industrial camera, controller, crushing mechanism, and cleaning mechanism, and through the coordinated design of the industrial camera and image processor, real-time visual monitoring of the degree of impurity accumulation on the filter screen surface is achieved. The controller can intelligently trigger the cleaning mechanism based on image analysis results, causing the first and second electric push rods to drive the scraper's extension, retraction, and angle adjustment. This closed-loop control breaks through the traditional mechanical mode of timed cleaning, avoiding energy waste caused by over-cleaning and preventing filtration efficiency decline due to impurity blockage, effectively improving the system's adaptability.

[0015] 2. This invention provides an urban sewage filtration device. By setting up a crushing mechanism, the crushing mechanism drives the first and second gears, which are meshed by a first forward and reverse motor, to drive the first and second crushing rollers to simultaneously crush the intercepted impurities, crushing large-sized impurities to a particle size that can pass through the conveying mechanism, thus fundamentally solving the problem of impurities blocking the conveying pipeline in the prior art.

[0021] like Figure 1 , Figure 5 and Figure 6As shown in the figure, a specific embodiment of the present invention provides an urban sewage filtration device. The cleaning mechanism 11 includes a first ball seat 1101 and a second ball seat 1105. Both the first ball seat 1101 and the second ball seat 1105 are fixedly connected inside the crushing chamber 4. A first rotating ball 1102 and a second rotating ball 1106 are rotatably connected inside the first ball seat 1101 and the second ball seat 1105. The right end of the first electric push rod 1103 is fixedly connected to the surface of the first rotating ball 1102, and the right end of the second electric push rod 1107 is fixedly connected to the surface of the second rotating ball 1106. A scraper 1104 is fixedly connected to the left end of the first electric push rod 1103. The scraper 1104 is in contact with the surface of the filter screen 18. A through hole 17 is opened in the middle of the partition 2, and the first electric push rod 1103 passes through the through hole. Inside the filter chamber 3, a U-shaped seat 1108 is fixedly connected to the lower surface of the first electric push rod 1103, and the upper end of the second electric push rod 1107 is movably connected to the inside of the U-shaped seat 1108. A water outlet mechanism 12 is provided inside the filter chamber 3. The water outlet mechanism 12 includes a housing 1201, which is fixedly connected inside the filter chamber 3. A water outlet pipe 1202 is connected to the lower end of the housing 1201, and the lower end of the water outlet pipe 1202 extends out of the filter chamber 3 to discharge the filtered wastewater. A collection element 13 is provided inside the crushing chamber 4, and the lower end of the collection element 13 extends out of the crushing chamber 4. A conveying mechanism 14 is connected to the lower end of the collection element 13. The conveying mechanism 14 includes a conveying shell 1401, and the lower end of the collection element 13 is connected to the conveying shell 1401. A second forward / reverse motor 1402 is provided at the left end of the housing 1401. The output end of the second forward / reverse motor 1402 is rotatably connected to the inside of the conveying housing 1401. A third rotating rod 1403 is fixedly connected to the output end of the second forward / reverse motor 1402. A spiral blade 1404 is provided on the surface of the third rotating rod 1403. The spiral blade 1404 is rotatably connected to the inside of the conveying housing 1401. A drain pipe 1405 is provided on the lower surface of the left end of the conveying housing 1401 so that the sewage in the conveying housing 1401 can be discharged through the drain pipe 1405. The conveying mechanism 14 is used to transport impurities in the crushing chamber 4. The conveying housing 1401 extends from top to bottom and is inclined towards the adjacent filter chamber 3. When the first electric push rod 1103 completes one push and the scraper 1104 begins to reset... Under the control of the controller 8, the second electric push rod 1107 raises the scraper 1104 and the first electric push rod 1103 to a certain height, preventing the scraper 1104 from pushing impurities to the outer wall of the filter chamber 3, making them difficult to clean. When the scraper 1104 is fully reset, the second electric push rod 1107 releases its force, and the scraper 1104 falls back to the position close to the filter screen 18. The filtered water flows into the water outlet mechanism 12 below, which facilitates the discharge of filtered sewage. The crushed impurities fall into the collection part 13 at the bottom of the crushing chamber and enter the inclined conveying shell 1401. The second forward and reverse motor 1402 drives the spiral blade 1404 to rotate, pushing the solid impurities to the right to the designated collection point. At the same time, the sewage is discharged through the drain pipe 1405 at the bottom during the conveying process, realizing solid-liquid separation.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, a sealing door 16 is provided on the front side of the housing 1, which corresponds to the filter screen 18 and the industrial camera 7. A support leg 15 is provided at the lower end of the housing 1. The filter screen 18 extends from top to bottom and is inclined away from the crushing chamber 4. The end of the filter screen 18 adjacent to the crushing chamber 4 is flush with the lower end face of the through hole 17. The outer shell 1201 is located below the filter screen 18. The cross-sectional area of ​​the upper end of the outer shell 1201 gradually decreases from top to bottom. The filter screen 18 and the industrial camera 7 can be quickly inspected or replaced through the sealing door 16 on the front side. The support leg 15 at the bottom of the housing 1 provides stable support to avoid vibration affecting the imaging accuracy of the industrial camera. The inclined design of the filter screen 18 causes the water flow to generate a downward component force, accelerating the sliding of impurities onto the surface of the filter screen 18. The outer shell 1201 of the water outlet mechanism 12 adopts a tapered structure with a larger upper part and a smaller lower part. The cross-sectional area change forms a confluence acceleration, and the sewage is quickly discharged through the water outlet pipe 1202.

[0023] Working principle: Wastewater enters the filter chamber 3 through the inlet pipe 5 on the left and flows through the inclined filter screen 18. The inclined design of the filter screen 18 creates a downward force on the water flow, accelerating the sliding of impurities onto the surface of the filter screen 18. The filtered water flows into the outlet mechanism 12 below. The outer shell 1201 of the outlet mechanism 12 adopts a tapered structure with a larger top and a smaller bottom, forming a convergence acceleration through the change in cross-sectional area. The wastewater is quickly discharged through the outlet pipe 1202. The industrial camera 7, fixed at the lower end of the inlet pipe 5, captures real-time images of the surface of the filter screen 18. The image data is transmitted to the image processor in the controller 8 to analyze the thickness and distribution of impurity accumulation. When the image processor detects that the impurity accumulation exceeds a preset threshold, the controller 8 sends a command to the cleaning mechanism 11 to activate the first electric push rod 1103. The left end of the first electric push rod 1103 is connected to a scraper 1104, which cleans the surface of the filter screen 18. After one feeding cycle, when the scraper 1104 begins to reset, the second electric push rod 1107, under the control of the controller 8, raises the scraper 1104 and the first electric push rod 1103 to a certain height to prevent the scraper 1104 from pushing impurities to the outer wall of the filter chamber 3, making them difficult to clean. When the scraper 1104 is fully reset, the second electric push rod 1107 releases its force, and the scraper 1104 falls back to a position close to the filter screen 18. The scraped impurities slide along the filter screen 18 into the through hole 17 on the partition and fall into the crushing chamber 4 on the right. The controller 8 simultaneously starts the first forward and reverse motor 901, driving the first gear 903 to mesh with the second gear 904, causing the first crushing roller 905 and the second crushing roller 907 to rotate in opposite directions, shearing and crushing the impurities, reducing their particle size to a size that can pass through the subsequent conveying mechanism 14. The dual-gear transmission ensures that the two crushing rollers rotate at the same speed, preventing impurities from getting stuck in the gap between the rollers due to speed difference. The crushed impurities fall into the collector 13 at the bottom of the crushing chamber and enter the inclined conveying shell 1401. The second forward and reverse motor 1402 drives the spiral blades 1404 to rotate, pushing the solid impurities to the right to the designated collection point. At the same time, the sewage is discharged through the drain pipe 1405 at the bottom during the conveying process, realizing solid-liquid separation. The filter screen 18 and industrial camera 7 can be quickly inspected or replaced through the front sealing door 16. The support legs 15 at the bottom of the shell 1 provide stable support to prevent vibration from affecting the imaging accuracy of the industrial camera.
