Technical Field
[0001] This utility model relates to the field of wastewater treatment, and in particular to an intelligent, efficient, green and low-carbon sludge removal and cleaning device for sedimentation tanks. Background Technology
[0002] In recent years, with the acceleration of national modernization and urbanization, provinces and cities have further strengthened the discharge standards for sewage treatment plants. Advanced sewage treatment processes have been gradually implemented in sewage treatment plants across the country. High-efficiency sedimentation tank technology has very important practical significance in advanced sewage treatment. Sedimentation tank is one of the most important facilities and equipment in sewage treatment.
[0003] The function of a sedimentation tank is to utilize the settling property of suspended particles in water, causing them to settle under the influence of gravity, thereby achieving solid-liquid separation. In this process, the sludge hopper, as a key structure at the bottom of the sedimentation tank, is used to collect and concentrate the settled sludge. During sludge suction, the sludge suction device above the hopper lacks the function of real-time detection of the remaining sludge amount. This may lead to inaccurate control in the sludge treatment process, causing the sludge suction device to work continuously and run dry. Since the sludge settles at the bottom, it is impossible to thoroughly remove some dead cleaning areas, resulting in incomplete sludge discharge from the purified water, low purification level, and reduced overall treatment effect.
[0004] Therefore, in response to the lack of real-time detection of the remaining sludge volume in the sludge suction device above the sludge discharge bucket during operation, the sludge suction device works continuously and runs dry, making it impossible to thoroughly remove some dead cleaning areas, resulting in incomplete sludge discharge from the purified water and low purification level, a smart, efficient, green and low-carbon sedimentation tank sludge discharge and cleaning device can be designed. Utility Model Content
[0005] To overcome the problem that the sludge suction device at the top of the sludge discharge bucket lacks the function of real-time detection of the remaining sludge during operation, which may lead to inaccurate control in the sludge treatment process, the sludge suction device will continue to work and run dry. Since the sludge settles at the bottom, it is impossible to thoroughly clean some dead corners, resulting in incomplete sludge discharge from the purified water.

A circulating cleaning module for cleaning the sludge hopper and preventing residue is provided on the side of the sedimentation tank.
[0007] Preferably, a sedimentation tank is used for solid-liquid separation of suspended particles in wastewater solution. Multiple sludge hoppers are linearly arranged at the bottom of the sedimentation tank for storing deposited sludge, forming a decentralized storage operation. Sludge suction pipes are set in the sedimentation tank at the corresponding positions of the sludge hoppers for suctioning the deposited sludge. An ultrasonic sludge level gauge is used to monitor parameters such as sludge level and residual sludge in real time. The detected data is transmitted back to the control terminal through pipelines, thereby allowing real-time adjustment of the sludge suction rate of the suction pipes. In conjunction with a high-pressure water gun, a circulating cleaning module is connected to a circulating water pipe to clean the sludge hoppers and prevent residue.
[0008] Preferably, the sedimentation tank has a sludge separation space inside, and the side wall of the sedimentation tank has an installation hole for installing a sludge suction pipe.

[0011] Preferably, the U-shaped water pipe is linearly provided with multiple sets of first lifting water pumps corresponding to the connecting pipe, and the end of the U-shaped water pipe away from the first lifting water pump is provided with a second lifting water pump for guiding water flow into the first high-pressure water gun.

[0014] The beneficial effects of this utility model are:
[0015] 1. Previously, when pumping sludge, the sludge suction device at the top of the sludge discharge bucket lacked real-time sludge monitoring capabilities. This resulted in continuous operation and dry running, and because the sludge settled at the bottom, it was impossible to thoroughly clean some hard-to-reach areas, leading to inconsistent sludge discharge from the purified water. In contrast, using a sedimentation tank for wastewater treatment offers significant improvements. The sedimentation tank effectively promotes the settling of suspended particles in the wastewater solution, achieving solid-liquid separation. At the bottom of the sedimentation tank, multiple sludge hoppers are linearly installed for the dispersed storage of deposited sludge. Simultaneously, the installed sludge suction pipes can accurately suction the deposited sludge at the corresponding sludge hopper positions. An ultrasonic sludge level gauge can monitor key parameters such as sludge level height and residual sludge in real time. This allows us to adjust the suction rate of the sludge suction pipes in real time based on these parameters, avoiding dry running and sludge residue. A high-pressure water gun and a circulating cleaning module are also included. The circulating cleaning module is supplied with water through a circulating water pipe, ensuring sufficient cleaning power for the high-pressure water gun. High-pressure water jets not only thoroughly clean the sludge hopper to prevent sludge residue, but also circulate and clean the entire sedimentation tank, ensuring a complete cleaning effect. This design not only improves the efficiency of sludge treatment but also significantly enhances the purification quality of wastewater treatment. Attached Figure Description

[0025] Please see Figures 3-4In this embodiment, a settling tank 401 is provided on the inner wall of the sludge hopper 4. The circulating cleaning module 5 includes a connecting pipe 501, an inlet pipe 502, a U-shaped water pipe 503, a first lifting water pump 504, a second lifting water pump 505, a guide pipe 506, and a first high-pressure water gun 507. The U-shaped water pipe 503 is located above the outer periphery of the sedimentation tank 1. A connecting pipe 501 is provided at the lower end of one side of the U-shaped water pipe 503. Multiple sets of connecting pipes 508 connected to the U-shaped water pipe 503 are linearly provided on the connecting pipe 501. The outer end is connected to an inlet pipe 502. Multiple sets of first lifting water pumps 504 corresponding to the connecting pipe 508 are linearly arranged on the U-shaped water pipe 503. A second lifting water pump 505 for guiding water flow into the first high-pressure water gun 507 is provided at the end of the U-shaped water pipe 503 away from the first lifting water pump 504. Multiple sets of first high-pressure water guns 507 are sequentially connected along the inner side of the U-shaped water pipe 503. A rotary joint is provided between the U-shaped water pipe 503 and the first high-pressure water gun 507. A high-pressure water pump is provided inside the first high-pressure water gun 507.
[0026] Please see Figures 4-5 In this embodiment, a diaphragm pump 601 is provided at the top of the sludge suction pipe 6, and a starter motor is provided at the side end of the diaphragm pump 601. A wireless signal interaction module is electrically connected to the outer end of the starter motor. A suction main pipe 603 is provided at the lower end of the sludge suction pipe 6, and a sludge discharge pipe 602 is fixedly connected to the top of the sludge suction pipe 6. Multiple sets of branch pipes 604 extending into the sludge hopper 4 are provided along the bottom edge of the suction main pipe 603. An electromagnetic control valve 605 is provided at the center of the branch pipe 604. A signal receiver and an ultrasonic sludge level gauge 606 are electrically connected to the side end of the electromagnetic control valve 605. An annular water pipe 607 is fixedly fitted around the periphery of the branch pipe 604. Multiple sets of second high-pressure water guns 608 are circumferentially connected to the outer end of the annular water pipe 607. A rotary joint is provided between the annular water pipe 607 and the second high-pressure water guns 608. A high-pressure water pump is provided inside the second high-pressure water guns 608. A water inlet pipe 609 is connected to the side end of the annular water pipe 607.
[0027] During operation, the inlet tank 3 is first connected to the sewage pipe via hopper 301, while the outlet tank 2 is connected to the outlet pipe. When the liquid flows into the sedimentation tank 1 through the inlet 302, suspended particles will sink to the sludge hopper 4 due to gravity. The liquid continues to rise and undergoes further separation through the inclined plate. Some of the liquid is quickly pumped out through the outlet tank 2. At this time, the ultrasonic sludge level gauge monitors the sludge level and residual sludge in the tank in real time.
[0028] Once the preset sludge discharge conditions are met, the PLC control cabinet will start the motor via the wireless signal interaction module, thereby controlling the diaphragm pump 601 to perform the sludge pumping operation. Simultaneously, upon receiving the command, the signal receiver will open the electromagnetic control valve 605. At this time, external water enters the annular water pipe 607 through the inlet pipe 502 and the lead pipe 609. Multiple sets of first-stage lift pumps 504 raise the water flow to the connecting pipe 508, and partially enter the U-shaped water pipe 503. The second-stage lift pump 505 then controls the pressure to fill the entire U-shaped water pipe 503, creating water pressure.
[0029] Subsequently, the high-pressure water pump drives the first high-pressure water gun 507 to perform deep cleaning of the sedimentation tank 1, ensuring thorough removal of dirt. Simultaneously, the high-pressure water pump also drives the second high-pressure water gun 608 to perform auxiliary cleaning from top to bottom. Under water pressure, the second high-pressure water gun 608 rotates via a rotary joint, further enhancing the cleaning effect.
[0030] During the operation of the diaphragm pump 601, fluid enters the diaphragm chamber or a specific chamber of the hydraulic cylinder. Taking the diaphragm type as an example, when the driving fluid enters the lower chamber of the diaphragm, the pressure in the lower chamber increases, pushing the diaphragm upward and causing the valve plate to rise, thereby opening the sludge discharge channel. At this time, sludge and other debris at the bottom of the tank begin to be discharged through the valve under the flushing action of the water flow, and the pump is in the open state. When the direction of the driving fluid changes, the pressure state in the diaphragm chamber or hydraulic cylinder also changes accordingly. If the driving fluid enters the upper chamber of the diaphragm, the pressure in the upper chamber increases, the diaphragm moves downward, causing the valve plate to descend, closing the sludge discharge channel, stopping the sludge discharge operation, and the pump is in the closed state. This design not only enhances the impact resistance of the sludge but also significantly improves the cleaning effect.
[0031] Through the above steps, sedimentation tank 1 can be used to separate solids and liquids by settling suspended particles in wastewater solution. Multiple sets of sludge hoppers 4 are linearly arranged at the bottom of sedimentation tank 1 to store deposited sludge in a decentralized storage manner. Sludge suction pipes 6 are set in sedimentation tank 1 at the positions corresponding to sludge hoppers 4 to suction the deposited sludge. Ultrasonic sludge level gauges are used to monitor parameters such as sludge level height and residual sludge in real time and transmit them to the backend, thereby allowing for real-time control of the sludge suction rate of the suction pipe. In conjunction with high-pressure water guns, the sludge hoppers 4 can be cleaned by connecting to the circulating water supply through the circulating cleaning module 5 to prevent residue from remaining.
