[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-2This utility model provides an embodiment of a coagulation reaction tank with a stirring function, comprising a reaction tank body 1. A motor 2 is fixedly connected to the top of the reaction tank body 1, and a drive wheel 3 is fixedly connected to the drive end of the motor 2. The motor 2 can rotate the drive wheel 3 by starting it. A belt 4 is sleeved on the outside of the drive wheel 3, and the rotation of the drive wheel 3 can rotate the belt 4. A groove 5 is formed inside the top of the reaction tank body 1, and the outside of the drive wheel 3 is rotatably connected to the inner wall of the groove 5, thus making the drive wheel 3 more stable when rotating. The rear end of the inner wall of the groove 5 is rotatably connected to... A driven wheel 6 is connected to the drive wheel 3, and the other end of the belt 4 is sleeved on the outside of the driven wheel 6. The rotation of the belt 4 causes the driven wheel 6 to rotate, thereby causing the driving wheel 3 to rotate synchronously with the driven wheel 6. The bottom of both the driving wheel 3 and the driven wheel 6 are fixedly connected to the drive shaft 7. The rotation of the driving wheel 3 and the driven wheel 6 causes the drive shaft 7 to rotate. The bottom of the drive shaft 7 is rotatably connected to the bottom inner wall of the reaction tank body 1, which makes the drive shaft 7 more stable when rotating. A stirring blade 8 is fixedly connected to the outside of the drive shaft 7. The rotation of the drive shaft 7 drives the stirring blade 8 to rotate, thereby mixing the wastewater with the coagulated water. The agents are mixed and stirred. Multiple slots 9 are provided on the outside of the stirring blades 8. The design of the slots 9 alters the fluid path, thereby increasing the mixing effect. A feed box 10 is fixedly connected to the top right end of the reaction tank body 1, through which materials are added. A feed block 11 is fixedly connected to the inner wall of the left end of the feed box 10, connecting to the reaction tank body 1 so that materials can be added into the interior of the reaction tank body 1. A discharge pipe 12 is fixedly connected to the bottom right end of the reaction tank body 1, with a valve at the top. The start of the motor 2 drives the drive wheel 3 to rotate. The rotation of the drive wheel 3 drives the belt 4 to rotate, which in turn drives the driven wheel 6 to rotate. The rotation of the drive wheel 3 and the driven wheel 6 drives the transmission shaft 7 to rotate, which in turn drives the stirring blades 8 to rotate. This stirs the wastewater and coagulant inside the reaction tank body 1, mixing them together. The flow path is changed by the slots 9, which increases the mixing effect and improves the mixing efficiency between wastewater and coagulant. After mixing, the mixture is allowed to stand still, and finally, the treated water is discharged from the discharge pipe 12 by opening the valve.
[0023] refer to Figure 1-3A buoyancy assembly is slidably connected to the top right end of the reaction tank body 1. The buoyancy assembly includes a buoyancy rod 13, a buoyancy ball 14, a limiting block 15, a blocking block 16, and a chute 17. The buoyancy rod 13 is slidably connected to the top right end of the reaction tank body 1, and the buoyancy ball 14 is fixedly connected to the bottom of the buoyancy rod 13. The buoyancy ball 14 can float on the sewage added. The limiting block 15 is fixedly connected to the bottom right end of the buoyancy rod 13, which restricts the buoyancy rod 13. The blocking block 16 is fixedly connected to the right end of the buoyancy rod 13, and the outside of the blocking block 16 is in contact with the inner wall of the reaction tank body 1. This is to allow the blocking block 16 to block the feed inlet of the reaction tank body 1. The chute 17 is opened on the inner wall of the right end of the reaction tank body 1, and the outside of the limiting block 15 is slidably connected to the inner wall of the chute 17, which restricts the limiting block 15. Support plates 18 are fixedly connected to both the front and rear sides of the feed box 10. The left end of the support plate 18 is fixedly connected to the top right end of the reaction tank body 1. Gears 19 are rotatably connected to opposite sides of the two support plates 18. Gears 19 are meshed with buoyancy rods 13. The sliding of buoyancy rods 13 causes gears 19 to rotate. A rack plate 20 is slidably connected to the top of the feed box 10. The rack plate 20 is meshed with gears 19. The rotation of gears 19 causes rack plate 20 to slide. A baffle 21 is fixedly connected to the bottom of rack plate 20. The outside of baffle 21 is slidably connected to the inner wall of the feed box 10 to ensure the stability of the baffle 21. The outside of baffle 21 is in contact with the outside of the feed block 11. The sliding of baffle 21 blocks the feed block 11, thereby blocking the flow of material. When the reaction tank body... As the amount of sewage inside the reactor body increases, it pushes the buoyancy ball 14, which in turn pushes the buoyancy rod 13 upward. This upward movement of the buoyancy rod 13 carries the blocking block 16 and the chute 17 upward. When the buoyancy rod 13 reaches a certain position, it blocks the feed inlet of the reactor body 1. Simultaneously, the buoyancy rod 13 rotates the gear 19, which in turn causes the rack plate 20 to slide. This sliding motion of the rack plate 20 pushes the baffle 21 to move, blocking the feed block 11. The cooperation of the baffle 21 and the blocking block 16 completely blocks the feed block 11, preventing sewage from flowing into the reactor body 1 and thus preventing overflow, maintaining a certain water level. Support frames 22 are fixedly connected to both the front and rear sides of the reactor body 1.
[0024] Working principle: First, wastewater and coagulant are added through the feed box 10. As the wastewater inside the reaction tank 1 increases, it pushes the buoyancy ball 14, which in turn pushes the buoyancy rod 13 upwards. The rising of the buoyancy rod 13 carries the blocking block 16 and the chute 17 upwards. When it reaches a certain position, the blocking block 16 blocks the feed hole of the reaction tank 1. As the buoyancy rod 13 moves, it drives the gear 19 to rotate. This rotation causes the rack plate 20 to slide, which in turn pushes the baffle 21 to move. The movement of the baffle 21 blocks the feed block 11, thus completely blocking it and preventing the wastewater from flowing. The wastewater is introduced into the reaction tank body 1, thus preventing wastewater from overflowing and maintaining a certain water level. At this time, the motor 2 is started, which drives the drive wheel 3 to rotate. The rotation of the drive wheel 3 drives the belt 4 to rotate, which in turn drives the driven wheel 6 to rotate. The rotation of the drive wheel 3 and the driven wheel 6 drives the transmission shaft 7 to rotate, which in turn causes the stirring blades 8 to rotate, thereby stirring and mixing the wastewater and coagulant inside the reaction tank body 1. The flow path is changed by the slots 9, which increases the mixing effect and improves the mixing efficiency between wastewater and coagulant. After mixing, the mixture is allowed to stand still, and finally, the treated water is discharged from the discharge pipe 12 by opening the valve.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
