Description

Technical Field

[0001] This invention relates to the field of sludge treatment, specifically to an intelligent municipal sludge treatment system. Background Technology

[0002] Intelligent municipal sludge treatment systems refer to comprehensive management systems that utilize modern information technologies such as the Internet of Things, big data, artificial intelligence, and robotic automation to monitor, collect data, analyze intelligently, optimize control, and make smart decisions for the entire sludge treatment process (generation, transportation, treatment, and disposal) in real time.

[0003] However, in existing intelligent municipal sludge treatment systems, the sludge needs to be flocculated after sedimentation. During the flocculation process, the sludge falls to the bottom of the sewage treatment tank due to its own gravity. As the sewage treatment volume increases, the amount of sludge accumulated in the sewage treatment tank also increases. However, since the bottom of the sewage treatment tank is horizontal with the ground, the sludge accumulated at the bottom of the sewage treatment tank is not easy to be discharged from the sewage pipe, thus increasing the cleaning work of the staff.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. 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.

[0020] like Figure 1 , Figure 2 , Figure 6An intelligent municipal sludge treatment system includes an intelligent sensing layer, an intelligent execution layer, and an intelligent management layer, all electrically connected. Due to this connection, sensors, flow meters, level gauges, video surveillance, and AI image recognition devices in the intelligent sensing layer can collect data throughout the entire process. The data acquisition and monitoring system, cloud computing and AI algorithm platform, and intelligent management platform in the intelligent management layer process, analyze, and make decisions based on the data collected by the intelligent sensing layer. The intelligent execution layer includes a sludge sedimentation tank and a wastewater treatment tank 1. A wastewater pretreatment pipe 2 is fixedly installed on the left side of the upper surface of the wastewater treatment tank 1. A filter assembly 3 is movably installed on the inner wall of the wastewater pretreatment pipe 2. Wastewater after sludge sedimentation falls from the inlet pipe 17 into the interior of the wastewater pretreatment pipe 2 under the drive of a pump. The wastewater passes through the filter assembly 3, causing impurities in the wastewater to settle. Above the wastewater pretreatment pipe 2, a pressure plate 4 is installed on the filter assembly 3. Stirring rods 5 are installed on the left and right sides inside the wastewater treatment tank 1. A scraper 6 is installed inside the wastewater treatment tank 1 below the stirring rods 5. A multi-stage electric push rod 7 is bolted to the right side of the upper end of the scraper 6. The scraper 6 is removed from the inside of the wastewater treatment tank 1 by retracting the multi-stage electric push rod 7 through the through hole 12. The bolts connecting the scraper 6 and the multi-stage electric push rod 7 to the lifting rod 31 can be removed and replaced. Mounting plates 8 are installed on the left and right sides above the wastewater treatment tank 1. The outer wall of the upper end of the multi-stage electric push rod 7 is fixedly sleeved with the mounting plate 8 on the right side. A moving component 9 for controlling the movement of the scraper 6 is provided on the right side of the mounting plate 8. Housings 10 are fixedly installed on the left and right sides of the wastewater treatment tank 1, and the housing 10 on the right side is installed outside the moving component 9.

[0021] A effluent pipe 36 is fixedly installed on the right side of the sewage treatment tank 1, located below the shell 10. Since a pump body is connected to the effluent pipe 36, the pump body is turned on to extract the flocculated sewage through the effluent pipe 36. A filter screen is fixedly installed inside the effluent pipe 36. A dosing pipe 11 is fixedly installed at the upper end of the sewage treatment tank 1, located to the right of the sewage pretreatment pipe 2. Sewage treatment flocculant is added to the inside of the sewage treatment tank 1 through the dosing pipe 11. A through hole 12 is opened at the upper end of the sewage treatment tank 1, located outside the dosing pipe 11 and the sewage pretreatment pipe 2. A first viewing window 13 is fixedly installed on the front of the sewage treatment tank 1. A sewage discharge groove 14 with the left side higher than the right side is provided on the bottom surface of the inner wall of the sewage treatment tank 1. A sewage discharge pipe 15 is fixedly installed on the right side of the sewage treatment tank 1, located below the effluent pipe 36, and the sewage discharge pipe 15 is connected to the sewage discharge groove 14.

[0022] A sealing door 16 is hinged to the front of the sewage pretreatment pipe 2, and a sealing ring is installed at the connection between the sealing door 16 and the sewage pretreatment pipe 2. The sealing door 16 and the sewage pretreatment pipe 2 are fixed by a locking buckle. An inlet pipe 17 is fixedly installed on the left side of the sewage pretreatment pipe 2, and the inlet pipe 17 is connected to the sludge sedimentation tank pipeline through the pump body. Several second viewing windows 18 are fixedly installed on the front of the sewage pretreatment pipe 2.

[0023] like Figure 3 , Figure 8 , Figure 9 The filter assembly 3 includes a first filter plate 301, a second filter plate 302, and a third filter plate 303. Since the filter holes on the first filter plate 301, the second filter plate 302, and the third filter plate 303 have different diameters, the wastewater on the first filter plate 301, the second filter plate 302, and the third filter plate 303 falls into the interior of the wastewater treatment tank 1 through the filter holes. The first filter plate 301, the second filter plate 302, and the third filter plate 303 are sequentially and equidistantly inserted into the interior of the wastewater pretreatment pipe 2 from top to bottom. The bottom surface of each of the three filter plates 303 is provided with filter holes, and the diameter of the filter holes on the first filter plate 301, the second filter plate 302 and the third filter plate 303 decreases in sequence. The outer walls of the first filter plate 301, the second filter plate 302 and the third filter plate 303 are all fixedly sleeved with extension plates 19. Several rollers 20 are respectively provided on the left and right sides of the extension plates 19, and the outer walls of the rollers 20 are tumblingly connected to the inner wall of the sewage pretreatment pipe 2. The front of the first filter plate 301, the second filter plate 302 and the third filter plate 303 is fixedly installed with a pull rod 21 located behind the sealing door 16.

[0024] A vertical electric push rod 22 is fixedly installed on the upper end of the pressure plate 4. Through the extension and retraction of the output shaft of the vertical electric push rod 22, the pressure plate 4 is moved towards the first filter plate 301, pressing the sludge on the first filter plate 301 and causing the sewage to fall into the sewage treatment tank 1. A disc 23 is fixedly sleeved on the outer wall of the vertical electric push rod 22. Several legs are evenly distributed on the outer wall of the disc 23, and the lower end of the legs is fixedly connected to the upper end face of the sewage pretreatment pipe 2.

[0025] A support rod 24 is movably sleeved on the outer wall of the front end of the stirring rod 5, and the upper end of the support rod 24 is fixedly connected to the sewage treatment tank 1. A conveying assembly 25 located behind the sewage treatment tank 1 is fixedly installed at the rear end of the stirring rod 5. A servo motor 26 is fixedly installed on the left end of the conveying assembly 25 away from the stirring rod 5. When the power of the servo motor 26 is turned on, the servo motor 26 drives the stirring rod 5 to rotate through the connection of the conveying assembly 25. Since the conveying assembly 25 consists of two synchronous pulleys and a conveyor belt, the two ends of the conveyor belt are respectively sleeved on the outer walls of the two synchronous pulleys. When the servo motor 26 drives one synchronous wheel to rotate, the rotation of the secondary synchronous wheel will drive the conveyor belt to move, and the conveyor belt will drive the other synchronous wheel to rotate. At this time, since both synchronous wheels are equipped with stirring rods 5, the rotation of the two synchronous wheels will drive the stirring rods 5 to stir and mix the sewage and flocculant in the sewage treatment tank 1. The outer wall of the servo motor 26 is fixedly fitted with a housing 27. The front end of the housing 27 is fixedly installed with a protective shell 28 located outside the conveying assembly 25, and the front of the protective shell 28 is fixedly connected to the back of the sewage treatment tank 1.

[0026] like Figure 4 , Figure 5 , Figure 7 The moving component 9 includes a ball nut 901 and a ball screw 902. The inner wall of the ball nut 901 is threadedly connected to the outer wall of the ball screw 902. The left side of the ball nut 901 is fixedly connected to the mounting plate 8 on the right side. A rotating shaft 29 is fixedly sleeved on the inner wall of the ball screw 902. A rotary motor 30 is fixedly mounted at the rear end of the rotating shaft 29, and the front end of the rotary motor 30 is fixedly connected to the back of the housing 10 on the right side. When the power to the rotary motor 30 is turned on, the rotation of the rotary motor 30 drives the ball screw 902 to rotate through the connection of the rotating shaft 29. Due to the threaded connection between the ball screw 902 and the ball nut 901, the ball screw 902 rotates in a circular motion while driving the ball nut 901 to move horizontally. As the ball nut 901 moves, it drives the scraper 6 to move on the bottom surface of the inner wall of the sewage treatment tank 1 through the connection of the mounting plate 8 on the right side. This pushes the sediment accumulated at the bottom of the sewage treatment tank 1 to the sewage discharge groove 14. Since the sewage discharge groove 14 is set as a slope that is higher on the left and lower on the right, the sediment is discharged from the sewage pipe 15 to the outside of the sewage treatment tank 1 under the action of the slope.

[0027] A lifting rod 31 is movably installed on the left side of the upper end of the scraper blade 6. A spring 32 is movably sleeved on the outer wall of the lifting rod 31. A limiting plate 33 located above the mounting plate 8 on the left side is fixedly installed on the upper end of the lifting rod 31.

[0028] The upper end of the spring 32 is fixedly connected to the lower end of the mounting plate 8 on the left side, and the lower end of the spring 32 is fixedly connected to the lower end of the lifting rod 31.

[0029] An annular block 34 is fixedly installed on the left side of the mounting plate 8, which is located inside the housing 10 on the left side. A round rod 35 is threaded onto the inner wall of the annular block 34, and the front and rear ends of the round rod 35 are movably connected to the front and rear sides of the inner wall of the housing 10 on the left side, respectively. A drive motor located behind the left housing is externally connected to the rear end of the round rod 35, and the front of the drive motor is fixedly connected to the back of the left housing. The output shaft of the drive motor passes through the housing and is connected to the round rod 35.

[0030] Working Principle: During use, the intelligent sensing layer, intelligent execution layer, and intelligent management layer are electrically connected. Sensors, flow meters, level gauges, video surveillance, and AI image recognition devices in the intelligent sensing layer can collect data from the entire process. The data acquisition and monitoring system, cloud computing and AI algorithm platform, and intelligent management platform in the intelligent management layer process, analyze, and make decisions based on the data collected by the intelligent sensing layer. After sludge sedimentation, the wastewater, driven by the pump, falls from the inlet pipe 17 into the wastewater pretreatment pipe 2. The wastewater sequentially passes through the first filter plate 301, the second filter plate 302, and the third filter plate 303, causing impurities in the wastewater to fall onto these plates. Due to the first filter plate 301, the second filter plate 302, and the third filter plate 303... The filter holes on the first filter plate 301, the second filter plate 302, and the third filter plate 303 are set with different diameter values. The sewage on the first filter plate 301, the second filter plate 302, and the third filter plate 303 falls into the sewage treatment tank 1 through the filter holes. The extension and retraction of the output shaft of the vertical electric push rod 22 moves the pressure plate 4 towards the first filter plate 301, pressing the sludge on the first filter plate 301 and causing the sewage to fall into the sewage treatment tank 1. Then, sewage treatment flocculant is added into the sewage treatment tank 1 through the dosing pipe 11. The power of the servo motor 26 is turned on. After the servo motor 26 is turned on, it drives the rotation of the stirring rod 5 through the connection of the conveying assembly 25. Since the conveying assembly 25 consists of two synchronous pulleys and a conveyor belt, the two ends of the conveyor belt are respectively sleeved on the two synchronous pulleys. When the servo motor 26 drives a synchronous wheel to rotate on the outer wall, the rotation of this synchronous wheel will drive the conveyor belt to move, and the conveyor belt will drive the rotation of another synchronous wheel. At this time, since both synchronous wheels are equipped with stirring rods 5, the rotation of the two synchronous wheels will drive the stirring rods 5 to stir and mix the sewage and flocculant in the sewage treatment tank 1. After the sewage treatment flocculant and the sewage inside the sewage treatment tank 1 are mixed, sediment will be produced, and the sediment will accumulate at the bottom of the sewage treatment tank 1. Since the outlet pipe 36 is connected to a pump body, the opening of the pump body will draw out the flocculated sewage through the outlet pipe 36. Subsequently, the drive motor and rotary motor 30 connected to the round rod 35 will be turned on synchronously, and the power supply to the drive motor and rotary motor 30 connected to the round rod 35 will be turned on. Subsequently, the opening of the rotary motor 30 drives the rotation of the ball screw 902 via the connection of the rotating shaft 29. Due to the threaded connection between the ball screw 902 and the ball nut 901, the circumferential rotation of the ball screw 902 simultaneously drives the horizontal movement of the ball nut 901. Simultaneously, the movement of the ball nut 901, through the connection of the mounting plate 8 on the right side, drives the scraper 6 to move on the bottom surface of the inner wall of the sewage treatment tank 1. At the same time, the opening of the drive motor drives the movement of the annular block 34 via the rotation of the round rod 35. Due to the threaded connection between the annular block 34 and the round rod 35, the circumferential rotation of the round rod 35 simultaneously drives the horizontal movement of the annular block 34. At this time, the movement of the annular block 34, through the lifting rod 31, drives the synchronous movement of the scraper 6.The sediment accumulated at the bottom of the sewage treatment tank 1 is pushed to the discharge groove 14. Since the discharge groove 14 is designed with a slope that is higher on the left and lower on the right, the sediment is discharged from the discharge pipe 15 to the outside of the sewage treatment tank 1 under the action of the slope. Finally, when it is necessary to clean the accumulated impurities in the filter assembly 3, the latch connecting the sealing door 16 and the sewage pretreatment pipe 2 is opened. After opening the sealing door 16, the filter assembly 3 can be pulled out from the sewage pretreatment pipe 2. Then, using the retraction of the multi-stage electric push rod 7, the scraper 6 is pushed through the through hole 12 and removed from the inside of the sewage treatment tank 1. The bolts connecting the scraper 6 and the multi-stage electric push rod 7 and the lifting rod 31 are removed, allowing for the replacement of the scraper 6.

The invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
