Description
Technical Field
[0001] This utility model relates to the technical field of water treatment equipment, and in particular to a mud and water treatment device for water plants. Background Technology
[0002] A sludge treatment device for water plants is a highly efficient device for purifying industrial wastewater. It uses processes such as coagulation and sedimentation to specifically treat suspended impurities in the sludge discharged from water plants, effectively recovering water resources and reducing the moisture content of discharged sludge, thus achieving environmental protection and water conservation. Existing sludge treatment devices typically inject sludge into an activated carbon reaction tank, followed by buffering and balancing in a balancing tank to stabilize the sludge entering the reaction flocculation tank. Then, with the agitation of the stirring components, reactants and magnetic powder are added to the reaction flocculation tank for treatment. The reacted sludge then enters a sedimentation tank for settling. However, in this structure, because coagulation and flocculation occur simultaneously in the reaction flocculation tank, the added reactants and magnetic powder easily mix and interfere with each other, leading to reduced coagulation and flocculation efficiency. Therefore, improvements are needed to address the aforementioned problems. Utility Model Content

Above the coagulation tank 5, magnetic mixing tank 6, and coagulation aid tank 7, a connecting pipe 14 is connected to a second support plate.

The inlet of the front water pump 18 is connected to the lower end of the activated carbon reaction tank 4 through the first inlet pipe, and the outlet of the front water pump 18 is connected to the balance conditioning tank 3 through the first outlet pipe. The inlet of the rear water pump 18 is connected to the balance conditioning tank 3 through the second inlet pipe, and the outlet of the rear water pump 18 is connected to the lower end of the coagulation tank 5 through the second outlet pipe. Solenoid valves are installed on both the first outlet pipe and the second inlet pipe, and the water pumps 18 facilitate the control of the flow and treatment of mud and water.
[0017] Working principle: When this utility model is used, the mud and water first flow into the activated carbon reaction tank 4, which is installed inside the upper end of the frame 1 and located on the other side of the reaction flocculation tank, through the connecting pipe. Then, the stirring assembly installed on the second support plate above the activated carbon reaction tank 4 is started. In this stirring assembly, the servo motor 13 drives the second rotating rod in the second drive box 19 to rotate through the coupling. The second rotating rod drives the second rotating shaft 15 to rotate through the cooperation of the second pulley and the second drive belt, thereby causing the stirring paddle 16 at the lower end of the second rotating shaft 15 to start running. At the same time, activated carbon is added into the activated carbon reaction tank 4. The activated carbon adsorbs some of the impurities in the mud and water, and the stirring paddle 16 makes the activated carbon and mud and water fully mixed, thereby improving the adsorption effect. After the initial adsorption treatment is completed, the front-end water pump 18, which is longitudinally installed at the lower middle of the frame 1, is started, and the solenoid valve on the first outlet pipe is opened. The front-end water pump 18 draws the sludge and water from the lower end of the activated carbon reaction tank 4 through the first inlet pipe, and then transports it through the first outlet pipe to the balancing and conditioning tank 3 on the other side of the front end of the sedimentation tank 2. Then, the relevant valves are closed, and sufficient sludge and water are allowed to enter the balancing and conditioning tank 3. When the sludge and water in the balancing and conditioning tank 3 reaches the required amount for treatment, the rear-end water pump 18 is started, and the solenoid valve on the second inlet pipe is opened. The rear-end water pump 18 draws the sludge and water from the balancing and conditioning tank 3 through the second inlet pipe, and simultaneously transports it through the second outlet pipe to the lower end of the coagulation tank 5 separated by the first partition plate in the reaction flocculation tank. Subsequently, the stirring components installed on the second support plates above the coagulation tank 5, magnetic mixing tank 6, and coagulation aid tank 7 are activated respectively. Each stirring component achieves stirring operation through the cooperation of the servo motor 13, the second drive box 19, the second rotating shaft 15, and the stirring paddle 16. At the same time, coagulant is added into the coagulation tank 5. Under the stirring action of the stirring paddle 16, the coagulant reacts fully with the mud and water. As the mud and water are continuously injected, its liquid level gradually rises and overflows the first isolation plate (the top surface of the first isolation plate is lower than the tank height of the coagulation tank 5 and the magnetic mixing tank 6). The mud and water flow into the magnetic mixing tank 6 from the top surface of the wall. At this time, magnetic powder is added into the magnetic mixing tank 6. The magnetic powder mixes with the mud and water under the stirring action. Then, the mud and water flow into the coagulation aid tank 7 through the rectangular connecting channel opened at the lower end of the second isolation plate (the magnetic mixing tank 6 and the coagulation aid tank 7 are separated by the second isolation plate). After further reaction is completed in the coagulation aid tank 7, as the mud and water are continuously added, its liquid level continues to rise and overflows the tank wall on the other side of the sedimentation tank 2 (the top surface of this tank wall is lower than the other tank walls of the sedimentation tank 2 and is parallel to the top surface of the tank wall on one side of the coagulation aid tank 7) and enters the sedimentation tank 2. After the muddy water enters the sedimentation tank 2, it will first come into contact with the anti-interference plate 17 (composed of multiple inclined parallel rectangular plates) connected by corner brackets at the lower end of the connecting plate on one side of the upper end of the sedimentation tank 2. The anti-interference plate 17 effectively prevents the continuously entering muddy water from colliding with the muddy water that has been initially separated in the sedimentation tank 2, thus avoiding a reduction in separation efficiency. During this process, the clear water in the muddy water enters the upper end of the sedimentation tank 2 through the anti-interference plate 17, and is then discharged through the flow pipe connected to one side of the sedimentation tank 2, while the impurities in the muddy water gradually sink to the bottom of the sedimentation tank 2.When the amount of impurities settled in the sedimentation tank 2 reaches a certain level, the geared motor 8 (located on the other side of the first drive box 9) installed on the first support plate at the upper middle of one side of the frame 1 is started. The drive shaft of the geared motor 8 drives the first rotating rod on the other side of the first drive box 9 to rotate through the coupling. The first rotating rod, with the cooperation of the first pulley in the middle and the first drive belt, drives the first rotating shaft 11 connected to the anti-interference pipe 10 (the anti-interference pipe 10 passes through the first support plate and the lower end passes through the anti-interference plate 17) on one side of the first drive box 9 to rotate. The sludge scraper 12 connected to the lower end of the first rotating shaft 11 rotates slowly. The multiple inclined sludge scrapers (the lower ends of the sludge scrapers abut against the lower inner wall of the sedimentation tank 2) installed on both sides of the lower end of the sludge scraper 12 operate synchronously to scrape and clean the impurities settled at the bottom of the sedimentation tank 2 and transport the impurities to the middle of the bottom of the sedimentation tank 2. Finally, the settled impurities are discharged in a concentrated manner, thus completing a complete mud and water treatment process.
[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
