Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a coagulant uniform dosing device for wastewater treatment. Background Technology
[0002] Coagulation is a crucial step in wastewater treatment. Coagulation is the process of agglomerating colloidal particles and tiny suspended solids in water. By adding coagulants, impurities are coagulated and flocculated, facilitating their separation from the water through subsequent sedimentation or filtration. Coagulants are typically evenly distributed into the treatment tank using a dosing device.
[0003] Existing devices mainly involve installing a spray dispensing assembly above the treatment tank. Many existing technologies are similar to a coagulant uniform dispensing device for wastewater treatment. The structure of CN218931817U includes a wastewater tank, a hydraulic rod fixed to its surface, a trough plate fixed to the top of the hydraulic rod, a placement groove on the top of the trough plate, a scraper sliding on the trough plate, a motor fixed to the trough plate, and a shaft fixed to the output end of the motor, the shaft being threadedly connected to the scraper. This invention solves the problem of uneven coagulant distribution in wastewater; however, there are still areas for improvement.
[0004] Existing devices mainly introduce flocculants through spray components, which makes it difficult for some devices to directly inject the coagulant into the wastewater, or to avoid some nozzles being blocked by flocculants. At the same time, some devices have difficulty in evenly dispersing the coagulant in the wastewater, thus hindering the rapid flocculation and sedimentation of the wastewater and reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a coagulant uniform dosing device for wastewater treatment is proposed. Utility Model Content

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.
[0026] Please see Figures 1-5 One embodiment provided by this utility model:
[0027] A coagulant uniform dosing device for wastewater treatment includes a base 11, a treatment tank 12, and a feeding box 15. The bottom of the treatment tank 12 is fixedly connected to the top left side of the base 11. A support frame 13 is fixedly connected to the top of the treatment tank 12. A lifting pipe 14 is inserted in the middle of the support frame 13. The bottom of the feeding box 15 is fixedly connected to the top right side of the base 11. A suction pump 16 is fixedly connected to the top left side of the feeding box 15. A feeding hose 17 is fixedly connected to the top of the suction pump 16. The other end of the feeding hose 17 is fixedly connected to the top right side of the lifting pipe 14. A lifting mechanism 2 is provided inside the left side of the support frame 13. A dispersing mechanism 3 is provided at the bottom of the lifting pipe 14. A control console 18 is fixedly connected to the front side of the feeding box 15.
[0028] The lifting mechanism 2 includes a servo motor 21. The top of the servo motor 21 is fixedly connected to the inner wall of the support frame 13. A drive shaft 22 is fixedly connected to the middle right side of the servo motor 21. A first bevel gear 23 is fixedly connected to the right end of the drive shaft 22. This design enables the servo motor 21 to drive the drive shaft 22 and the first bevel gear 23 to rotate in a limited position. A second bevel gear 24 is meshed with the right side of the first bevel gear 23. A transmission screw 25 is fixedly connected to the inner wall of the second bevel gear 24. Both ends of the transmission screw 25 are movably connected to the inner wall of the support frame 13. This design enables the first bevel gear 23 to mesh and drive the second bevel gear 24 and the transmission screw 25 to rotate in a limited position. The outer wall of the transmission screw 25 is threaded with a lifting sleeve 26 below the second bevel gear 24. The right side of the lifting sleeve 26 passes through the support frame 13 and is fixedly connected to the top left side of the lifting tube 14. Through this design, the transmission screw 25 drives the lifting sleeve 26 and the lifting tube 14 to slide up and down, so that the bottom end of the lifting tube 14 enters the interior of the treatment pool 12.
[0029] The bulk material handling mechanism 3 includes a rotating disk 31, whose connector is inserted into the bottom of the lifting pipe 14. A nozzle 32 is fixedly connected to the outer wall of the rotating disk 31. The nozzle 32 is curved in shape. Coagulant drawn by the suction pump 16 is sprayed through the nozzle 32, causing the sprayed coagulant to drive the nozzle 32 and the rotating disk 31 to rotate in a limited position. A bulk material handling blade 33 is fixedly connected to the outer wall of the rotating disk 31 between the nozzle 32. This design enables the rotating disk 31 to drive the bulk material handling blade 33 to rotate synchronously, allowing the bulk material handling blade 33 to disperse the high-concentration coagulant within the treatment tank 12.
[0030] A ball sleeve 34 is fixedly connected to the outer wall of the connector of the rotating disk 31. A ball bearing 35 is installed on the inner wall of the ball sleeve 34. A ball groove ring 36 is installed below the outer wall of the ball bearing 35. The bottom of the ball groove ring 36 is fixedly connected to the bottom of the inner wall of the lifting tube 14. Through the cooperation of the ball sleeve 34, the ball bearing 35 and the ball groove ring 36, the rotating disk 31 can rotate smoothly at the bottom of the lifting tube 14.
[0031] Working principle: When it is necessary to raise or lower the lifting tube 14, the servo motor 21 is first started through the control console 18. The servo motor 21 drives the transmission shaft 22 to rotate in a limited position. The transmission shaft 22 drives the first bevel gear 23 to rotate synchronously. The first bevel gear 23 meshes and drives the second bevel gear 24 to rotate. The second bevel gear 24 drives the transmission screw 25 to rotate in a limited position. The transmission screw 25 drives the lifting sleeve 26 to slide up and down. The lifting sleeve 26 drives the lifting tube 14 to slide synchronously, so that the bottom end of the lifting tube 14 enters the interior of the treatment pool 12, realizing the lifting and lowering operation of the lifting tube 14.
[0032] When it is necessary to distribute the coagulant, the suction pump 16 is first started through the control panel 18. The coagulant drawn by the suction pump 16 is sprayed out through the nozzle 32, which causes the sprayed coagulant to drive the nozzle 32 and the rotating disk 31 to rotate in a limited position. The rotating disk 31 drives the dispersing blades 33 to rotate synchronously, so that the dispersing blades 33 carry the high-concentration coagulant to disperse in the treatment tank 12, thus realizing the dispersing operation of the coagulant. The operation ends here.
