DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 As shown, a sewage recycling treatment device dedicated to slag from a municipal domestic waste incineration power plant comprises a shell 1, an anaerobic tank 6 is arranged in the shell 1, an aerobic tank 7 is arranged in the shell 1, a sedimentation tank 8 is arranged in the shell 1, a disinfection tank 9 is arranged in the shell 1, a blocking structure 2 is arranged in the shell 1, the blocking structure 2 comprises two grilles 201 mounted on the shell 1, two mounting frames 202 are fixedly connected to the shell 1, a rotating shaft 203 is rotatably connected to the mounting frame 202, and a plurality of stirring rods 204 are fixedly connected to the rotating shaft 203.

[0024] As a technical optimization scheme of the utility model, a motor 205 is installed on the installation frame 202, and the rotating shaft 203 is fixedly connected to the output shaft of the motor 205. A first through hole 10 is provided in the shell 1, a connecting pipe 11 is installed in the shell 1, an overflow weir 12 is fixedly connected in the shell 1, and a second through hole 13 is provided in the shell 1. Then, the water enters the anaerobic tank 6 in the shell 1 from the grille 201. The setting of the grille 201 facilitates the blocking of large floating objects in the sewage. The anaerobic tank 6 decomposes organic matter in the sewage through the action of anaerobic bacteria, produces methane, carbon dioxide and other gases, and converts organic nitrogen into ammonia nitrogen, thereby reducing chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Then, the water source enters the aerobic tank 7 through the first through hole 10. The aerobic tank 7 uses aerobic microorganisms to oxidize and decompose organic matter in the sewage through aerobic bacteria attached to the biofilm, thereby further removing ammonia nitrogen. The aerobic microorganisms convert ammonia nitrogen into nitric acid under aerobic conditions. Salt is added to purify the water quality. The water in the aerobic tank 7 then enters the sedimentation tank 8 through the connecting pipe 11. The sedimentation tank 8 uses gravity to settle the suspended matter and sludge in the sewage to the bottom to achieve mud and water separation. The settled sludge is returned to the anaerobic tank 6 or the aerobic tank 7 through the reflux system to maintain the sludge concentration of the treatment system and ensure the treatment effect. The water source finally flows from the overflow weir 12 and the second through hole 13 to the disinfection tank 9. The disinfection tank 9 kills bacteria, viruses and parasites in the water by adding disinfectants such as chlorine and ultraviolet rays to ensure that the treated water quality meets the discharge standards. The disinfected water can be safely discharged or reused. When the grille 201 blocks floating objects, the motor 205 can be started. When the output shaft of the motor 205 rotates, the rotating shaft 203 is driven to rotate. When the rotating shaft 203 rotates, the stirring rod 204 is driven to move, so that the stirring rod 204 stirs the water source at the grille 201 to avoid impurities accumulating at the grille 201 and blocking the grille 201, thereby avoiding affecting the sewage treatment.

[0025] As a technical optimization solution of the utility model, a cleaning structure 3 is provided between the mounting frame 202 and the shell 1, and the cleaning structure 3 includes a support plate 301 installed at the bottom of the mounting frame 202, and a connecting block 302 is fixedly connected to the bottom of the support plate 301, a first hydraulic rod 303 is installed on the mounting frame 202, and the connecting block 302 is fixedly connected to the telescopic end of the first hydraulic rod 303, a mounting plate 305 is fixedly connected to the shell 1, a fixing frame 306 is fixedly connected to the mounting plate 305, a second hydraulic rod 307 is installed on the fixing frame 306, and a push plate 308 is fixedly connected to the telescopic end of the second hydraulic rod 307, and a guide rod 304 is fixedly connected to the bottom of the support plate 301, and the guide rod 304 is slidably connected to the mounting plate 305. When it is necessary to clean the inside of the mounting frame 202 on one side, the extended third hydraulic rod 404 is contracted, and at the same time, the other third hydraulic rod 404 drives the baffle 4 02 rises, so that the water source flows into another installation frame 202. At this time, by starting the first hydraulic rod 303 on the corresponding installation frame 202, the telescopic end of the first hydraulic rod 303 is extended to drive the support plate 301 to move downward through the connecting block 302. When the support plate 301 moves downward, it drives the guide rod 304 to slide with the mounting plate 305. The sliding cooperation between the guide rod 304 and the mounting plate 305 makes the movement of the support plate 301 more stable. At this time, some impurities will fall with the support plate 301. After falling to a certain height, by starting the second hydraulic rod 307, the telescopic end of the second hydraulic rod 307 is extended to drive the push plate 308 to move, and the push plate 308 will push away the impurities on the support plate 301. At this time, the cleaning of the impurities on the support plate 301 is completed. The downward movement of the support plate 301 is convenient for cleaning the impurities in the installation frame 202. The cooperation between the two baffles 402 is convenient for diverting the sewage to avoid affecting the cleaning of the impurities in the installation frame 202.

At the same time, the fixed rod 403 will drive the guide column 405 to slide with the guide sleeve 406. The setting of the guide column 405 makes the movement of the baffle 402 more stable. After the baffle 402 moves upward, the sewage will flow to the corresponding installation frame 202.

The setting of the connecting rings 503 facilitates the transportation of the outer shell 1 in cooperation with the lifting equipment.

[0028] When the utility model is in use, the sewage is firstly passed through the external pipe into the water inlet pipe 407, and then one of the third hydraulic rods 404 is started. When the telescopic end of the third hydraulic rod 404 is extended, the fixed rod 403 is driven to move upward, and at the same time, the fixed rod 403 is driven to move upward when the fixed rod 403 moves upward, and at the same time, the fixed rod 403 is driven to slide with the guide column 405 and the guide sleeve 406. The setting of the guide column 405 makes the movement of the baffle 402 more stable. After the baffle 402 is upward, the sewage will flow into the corresponding installation frame 202, and then enter the anaerobic tank 6 in the housing 1 from the grille 201. The setting of the grille 201 is convenient for blocking large floating objects in the sewage. The anaerobic tank 6 removes organic matter in the sewage through the action of anaerobic bacteria. Decompose to produce gases such as methane and carbon dioxide, and at the same time convert organic nitrogen into ammonia nitrogen, reducing chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Then the water source will enter the aerobic tank 7 through the first through hole 10. The aerobic tank 7 uses aerobic microorganisms to oxidize and decompose organic matter in the sewage through aerobic bacteria attached to the biofilm to further remove ammonia nitrogen. Aerobic microorganisms convert ammonia nitrogen into nitrates under aerobic conditions, thereby purifying the water quality. The water in the aerobic tank 7 then enters the sedimentation tank 8 through the connecting pipe 11. The sedimentation tank 8 uses gravity to settle the suspended matter and sludge in the sewage to the bottom to achieve mud and water separation. The settled sludge is returned to the anaerobic tank 6 or the aerobic tank 7 through the reflux system to maintain the sludge concentration of the treatment system to ensure the treatment effect. The water source finally flows from the overflow weir 12 and the second through hole 13 to the disinfection tank 9. The disinfection tank 9 kills bacteria, viruses and parasites in the water by adding disinfectants such as chlorine and ultraviolet rays to ensure that the treated water quality meets the discharge standard. The disinfected water can be safely discharged or reused. When the grille 201 blocks floating objects, the motor 205 can be started. When the output shaft of the motor 205 rotates, the rotating shaft 203 is driven to rotate. When the rotating shaft 203 rotates, the stirring rod 204 is driven to move, so that the stirring rod 204 stirs the water source at the grille 201 to avoid impurities accumulating at the grille 201 and blocking the grille 201, thereby avoiding affecting the sewage treatment. When it is necessary to clean the inside of the installation frame 202 on one side, the extended third hydraulic rod 404 is used. The guide rod 304 and the mounting plate 305 are slidably matched with each other by the guide rod 304. The guide rod 304 and the mounting plate 305 are slidably matched with each other to make the movement of the support plate 301 more stable. At this time, some impurities will fall with the support plate 301. After falling to a certain height, the second hydraulic rod 307 is started. When the telescopic end of the second hydraulic rod 307 is extended, the push plate 308 is driven to move. The push plate 308 will push away the impurities on the support plate 301.At this time, the impurities on the support plate 301 are cleaned, and the support plate 301 moves downward to facilitate the cleaning of impurities in the installation frame 202. The two baffles 402 cooperate with each other to facilitate the diversion of sewage, thereby avoiding affecting the cleaning of impurities in the installation frame 202.
