Description

Technical Field

[0001] This invention relates to the field of sludge treatment equipment technology, specifically to a sludge treatment equipment for urban drainage pipe networks. Background Technology

[0002] With the rapid urbanization and urban population growth in my country, the per capita sludge discharge has been increasing, leading to a surge in sludge transportation volume in urban drainage networks. As urban areas expand and landfills are moved further away, sludge transportation costs have increased, and landfill area has expanded. Furthermore, the high water content of sludge in urban drainage networks causes secondary pollution due to leakage during transportation and leachate at landfills. Sludge collection ponds in urban drainage networks are supporting facilities, serving as transfer stations for sedimentation in sewage to reduce the risk of blockage in subsequent pipes. These ponds require regular transport by trucks to mix the sediment and transport it to designated landfill locations.

[0003] Existing urban drainage network sludge treatment equipment, while employing measures such as sedimentation of sludge and solids in drainage network sludge collection tanks or filtration with filter elements to reduce the risk of blockage in subsequent pipelines, has the following drawbacks in its use:

[0004] 1. There is a lack of an efficient, continuous and stable separation mechanism for sewage-sand mixtures. Direct extraction and transportation of sewage-sand mixtures can easily lead to leakage due to excessive water volume, causing secondary pollution to the environment. The environmental friendliness of the transfer during landfill is also poor. 2. There is a lack of an integrated mechanism for the discharge of sludge and solid waste. It is difficult to conveniently and directly load and transport sludge and solid waste using ordinary vehicles, resulting in poor ease of use. 3. There is a lack of an automatic cleaning and unblocking mechanism for the filter components during the treatment process. It is difficult to ensure smooth treatment during long-term sludge treatment.

[0005] To address the challenges of efficient, continuous, and stable separation of sewage-sludge mixtures, automatic discharge of sludge and solid waste, and automatic cleaning and unclogging of filters during treatment, we propose a sewage sludge treatment device for urban drainage networks. Summary of the Invention

[0059] In this implementation scheme, the water pump 301, three-way pipe 302, two second solenoid valves 303, two L-shaped pipes 304, multiple nozzles 305, and suction pipe 306 work together. The PLC controller 204 is used to pre-set the opening and closing times of the water pump 301, the left first solenoid valve 501, the left second solenoid valve 303, the right first solenoid valve 501, and the right second solenoid valve 303 according to the on-site cleaning application requirements. Specifically, during a timed cleaning period, the interval between the start and stop of the water pump 301 is set to four minutes. During the initial cleaning application, the water pump 301 is first turned on for four minutes, and the left first solenoid valve 501 and the left second solenoid valve 303 are closed. Valve 303 is opened for two minutes, then both valves are controlled to reset. Immediately afterwards, the first solenoid valve 501 on the right is closed and the second solenoid valve 303 on the right is opened for two minutes. After two minutes, both valves are controlled to reset, and water pump 301 is turned on. Each alternating cleaning interval is one hour; that is, after one hour, the above alternating cleaning steps are repeated, and so on. When the cleaning time is reached, PLC controller 204 first controls water pump 301 to open for four minutes and the first solenoid valve 501 on the left to close and the second solenoid valve 303 on the left to open for two minutes. At this time, the supply of sewage and sand mixture to the left-side transfer pipe 4 is paused. Water pump 301 then draws in the sewage and sand mixture. Water pipe 306 draws water from water tank 1 and pumps it into three-way pipe 302. The water is then supplied to the left-side L-shaped pipe 304 via the second solenoid valve 303 on the left, and then sprayed to the left by multiple nozzles 305 on the left to backwash and clean the rotating stainless steel filter screen 401 on the left. Two minutes later, PLC controller 204 controls the opening of the left-side first solenoid valve 501 and the closing of the left-side second solenoid valve 303, and controls the closing of the right-side first solenoid valve 501 and the opening of the right-side second solenoid valve 303. At this time, the supply of material to the right-side rotating pipe 4 stops, and the supply of water is switched to the right-side L-shaped pipe 304 via the right-side second solenoid valve 303. The water then flows through multiple nozzles 305 on the right. Nozzle 305 sprays water to the right to backwash and clean the rotating stainless steel filter screen 401 on the right side. After four minutes, PLC controller 204 controls the first solenoid valve 501 on the right side to open and the second solenoid valve 303 on the right side to close, performing a reset operation. After waiting for one hour, the same control operation is performed again to alternately backwash and clean the filter elements on both sides. This achieves the effect of automatically backwashing and cleaning the stainless steel filter screens 401 on both sides at regular intervals during use. While cleaning one side, the other side continues to perform fast filtration and slag discharge, ensuring continuous operation of solid-liquid fast filtration and discharge. After cleaning, it automatically switches to fast filtration and slag discharge on both sides simultaneously, achieving high efficiency and improving work efficiency.

[0060] It should be noted that the PLC controller 204 preferably adopts a Siemens S7-200SMART programmable controller with programmable time control function. By using the time control function of the programmable controller, the opening and closing times and intervals of the two first solenoid valves 501, the two second solenoid valves 303 and the water pump 301 can be set by programming, so as to start them at the appropriate time and realize the time control function of the corresponding steps. The above operations are all conventional applications of programmable controllers and are basic and well-known technical means of programmable controllers, which will not be described in detail here.

[0061] The specific specifications (such as density and filtration accuracy) of the stainless steel filter screen 401 can be selected according to the actual working conditions. That is, the appropriate pore size of the stainless steel filter screen 401 can be flexibly driven according to the required filtration particle size. Selecting the appropriate specifications according to the application is a mature and well-known conventional technical means in this field, and will not be elaborated further. In addition, the electrical connection between the drive motor 6, water pump 301 and sludge pump 101 and the PLC controller 204 is achieved through wires and servo drivers. The servo driver preferably adopts the Siemens V90 servo driver, which is a commonly used motor and water pump control driver that is commonly used with Siemens programmable controllers. It meets the requirements of the programmable controller to directly control the start and stop of the drive motor 6, water pump 301 and sludge pump 101. This method of establishing an electrical connection controlled by the PLC controller 204 through direct wire connection is a mature and well-known technology of conventional wired control of the controller, and will not be detailed here.

[0062] Regarding power supply, given that the urban drainage network sludge treatment site is a water treatment and processing facility with sufficient mains power supply facilities, all electrical components of this device are connected to the mains power supply on site. They are connected to the power input interfaces of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules, as well as flexible wires (not marked in the figure), forming a complete power supply circuit. This power supply scheme is a conventional power distribution method for industrial equipment and is a mature and well-known technical means, which will not be elaborated here.

[0063] This embodiment facilitates simultaneous rotary centrifugal rapid filtration of wastewater at two locations and centralized discharge of sludge and solid residue, achieving efficient and stable solid-liquid separation and diversion. The centralized discharge of sludge and solid residue allows for convenient transportation using ordinary vehicles directly at the discharge point. The solid-liquid separation method effectively reduces secondary pollution caused by excessive leakage during transport, improving ease of use and environmental friendliness. Furthermore, it allows for automatic backflushing and cleaning of the filter elements on both sides during continuous operation, ensuring stable and unobstructed solid-liquid rapid filtration and discharge, thus guaranteeing effective treatment. After cleaning, it automatically switches to simultaneous rapid filtration and sludge discharge from both sides, achieving high efficiency and improving work efficiency.

[0064] The usage method of this embodiment is as follows: When using the urban drainage network sludge treatment equipment, the device is fixedly installed on one side of the upper part of the drainage network sludge collection tank 100, so that the bottom ends of the L-shaped suction pipe 102 and the L-shaped overflow pipe 103 are both located inside the drainage network sludge collection tank 100. The opening and closing times of the water pump 301, the first solenoid valve 501 on the left, the second solenoid valve 303 on the left, the first solenoid valve 501 on the right, and the second solenoid valve 303 on the right are pre-set using the PLC controller 204 according to the on-site cleaning application requirements. During a timed cleaning period, the water pump 301... 01 The interval between start-up and shutdown is set to four minutes. During the initial cleaning application, the water pump 301 is turned on for four minutes, the first solenoid valve 501 on the left is turned off, and the second solenoid valve 303 on the left is turned on for two minutes. Then, both of them are controlled to reset. Next, the first solenoid valve 501 on the right is turned off and the second solenoid valve 303 on the right is turned on for two minutes. After two minutes, both of them are controlled to reset, and the water pump 301 is turned on. The time interval between each alternating cleaning is one hour. That is, after one hour, the above alternating cleaning steps are repeated. This process continues in sequence.

[0065] When the PLC controller 204 is started by personnel, it first controls the sludge pump 101 and drive motor 6 to start. When the sludge pump 101 starts, it draws the sludge-sand mixture from the sewage pool 100 in the drainage network through the L-shaped suction pipe 102 and pumps it into the horizontal pipe 5. The sludge-sand mixture is then diverted into the two rotary pipes 4 by the two first solenoid valves 501. When the drive motor 6 starts, it drives the first gear 601 to rotate. The first gear 601 drives the two external gear rings 602 meshing with it to rotate synchronously. 2. The two second gears 603 rotate in the opposite direction. The two second gears 603 drive the two middle synchronous pulleys 605 to rotate in the opposite direction to the two external gear rings 602 through the two rotating shafts 604, the two outer synchronous pulleys 605 and the two synchronous belts 606. The synchronous rotation of the two outer gear rings 602 drives the two rotating pipes 4 to rotate synchronously. The rotating pipes 4 drive the four corresponding stainless steel filter screens 401 to rotate, quickly throwing out the sewage that enters them and intercepting and filtering the mud and solids inside the rotating pipes 4. When the two synchronous wheels 605 in the middle rotate in the opposite direction to the two external gear rings 602, the two central shafts 404 drive the two spiral conveying blades 405 to rotate in the opposite direction to the rotating pipe 4. The rotation of the two spiral conveying blades 405 realizes the upward conveying of the filtered sludge and solid residue. The conveyed sludge and solid residue are discharged through the two inclined pipes 406 into the slag discharge pipe 407 for centralized discharge. A transport box for receiving slag is placed below the rear end of the slag discharge pipe 407. This achieves the effect of two-point rotary centrifugal rapid filtration of sewage and upward conveying of sludge and solid residue for centralized discharge. The real-time integrated discharge of sludge and solid residue, combined with the simultaneous rapid filtration and solid residue conveying on both sides, achieves efficient and stable solid-liquid separation, improving the long-term continuous stability of filtration. Furthermore, the direct discharge of sludge and solid residue allows for easy transportation by ordinary vehicles at the discharge point. The solid-liquid separation effectively reduces the secondary pollution caused by large-volume leakage during transportation, improving ease of use and environmental friendliness.

[0066] In the centrifugal rapid filtration process, two drain pipes 205 are used to discharge the filtered water into the water tank 1. When there is a lot of water in the water tank 1, the L-shaped overflow pipe 103 is used to overflow the water after solid-liquid separation back into the sewage sludge tank 100 of the drainage network for further discharge into the network. In addition, during the centrifugal rapid filtration and solid sludge discharge processes, when the preset cleaning time is reached, the PLC controller 204 first controls the water pump 301 to start for four minutes and the first solenoid valve 501 on the left side to close and the second solenoid valve 30 on the left side to close. 3. After two minutes of operation, the supply of sewage and sand mixture to the left-hand pipe 4 is paused. At this time, water pump 301 draws water from water tank 1 through suction pipe 306 and pumps it into three-way pipe 302. The water is then supplied to the left-hand L-shaped pipe 304 through the second solenoid valve 303, and then sprayed to the left through multiple nozzles 305 to backwash and clean the rotating stainless steel filter screen 401 on the left. After two minutes, PLC controller 204 controls the opening of the first solenoid valve 501 and the second solenoid valve 303 on the left. The system closes and controls the first solenoid valve 501 on the right to close and the second solenoid valve 303 on the right to open. At this time, the material supply to the right-side rotary pipe 4 stops, and water is supplied to the right-side L-shaped pipe 304 through the second solenoid valve 303. The water is then sprayed to the right through multiple nozzles 305 on the right to backwash and clean the rotating stainless steel filter screen 401. After four minutes, the PLC controller 204 controls the first solenoid valve 501 on the right to open and the second solenoid valve 303 on the right to reset. After waiting for one hour, the same control operation is performed again to backwash and clean the filter elements on both sides alternately. This process is repeated to achieve the effect of automatically backwashing and cleaning the stainless steel filter screen 401 on both sides at regular intervals. While cleaning one side, the other side continues to perform fast filtration and slag discharge, ensuring the continuous, stable and smooth operation of the solid-liquid fast filtration and discharge, thus ensuring smooth processing. After cleaning, the system automatically switches to fast filtration and slag discharge on both sides simultaneously, achieving high efficiency and improving work efficiency. Example 2

[0067] like Figure 5As shown, this embodiment differs from Embodiment 1 in that the same lever-type air-blowing auxiliary discharge mechanism is also installed on the upper circular plate 202, the slag discharge pipe 407, and the second synchronous wheel 605 on the left. This lever-type air-blowing auxiliary discharge mechanism is used to automatically blow gas from the front into the slag discharge pipe 407 during centrifugal rapid filtration, utilizing the rotational power of the second synchronous wheel 605 on the left, to assist in its rapid backward slag discharge. The lever-type air-blowing auxiliary discharge mechanism includes a circular protective tube 7, a box-shaped filter screen 701, a connecting shaft 702, a centrifugal impeller 703, a first L-shaped air vent pipe 704, and a second L-shaped air vent pipe 705. The connecting shaft 702 is rotatably embedded in the top left side of the upper circular plate 202. The bottom end of the connecting shaft 702 is fixedly connected to the top of the second synchronous wheel 605 on the left. The centrifugal impeller 703 is located inside the circular protective tube 7 and is fixedly connected to the top end of the connecting shaft 702. The bottom of the box-shaped filter screen 701 is set as an opening and is fixedly connected to the top end of the circular protective tube 7. The first L-shaped vent pipe 704 is connected and fixedly fixed to the right front side of the circular protective tube 7. The upper circular plate 202 is fixedly sleeved on the first L-shaped vent pipe 704. The second L-shaped vent pipe 705 is connected and fixedly fixed between the bottom end of the first L-shaped vent pipe 704 and the front end of the slag discharge pipe 407.

[0068] In this embodiment, a fourth circular hole is provided on the top left side of the upper circular plate 202, and a second bearing is fixedly sleeved in the fourth circular hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the connecting shaft 702, so as to achieve the effect of rotating the connecting shaft 702.

[0069] This embodiment can automatically supply gas to the slag discharge pipe 407 during centrifugal rapid filtration to assist in the rapid backward slag discharge, reduce the static accumulation of mud and sand solids in the slag discharge pipe 407, and further improve the smoothness of slag discharge.

[0070] The method of use in this embodiment is as follows: The difference from Embodiment 1 is that it also has the following functions: By using the set round protective tube 7, box-shaped filter screen 701, connecting shaft 702, centrifugal impeller 703, first L-shaped air pipe 704 and second L-shaped air pipe 705 in cooperation, when the second synchronous wheel 605 on the left rotates, it also drives the centrifugal impeller 703 to rotate through the connecting shaft 702. When the centrifugal impeller 703 rotates, it draws in external air through the box-shaped filter screen 701 and supplies it downward. The gas is blown from the front end to the slag discharge pipe 407 through the first L-shaped air pipe 704 and the second L-shaped air pipe 705 in sequence. This realizes the effect of automatically supplying gas to the slag discharge pipe 407 during centrifugal fast filtration to assist the rapid discharge of slag, reducing the phenomenon of static accumulation of mud and sand solid slag in the slag discharge pipe 407, and further improving the smoothness of slag discharge.
