[0002] Water treatment methods include physical treatment and chemical treatment. Humans have been treating water for many years. Physical methods include using filter materials with different pore sizes to remove impurities from the water by adsorption or barrier methods. The most important adsorption method is adsorption with activated carbon. The barrier method is to pass water through the filter material to prevent larger impurities from passing through, thereby obtaining cleaner water.

[0003] Traditionally, some drugs need to be added in sewage treatment projects, but the traditional dosing device has a simple structure. Multiple drugs are added to the mixing box in appropriate proportions each time, and then discharged into the treatment pool. In this way, drugs need to be added again every time water is treated, which greatly increases the workload of the staff. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0019] Example 1: A dosing device for water treatment, see Figures 1 to 5, including a drug mixing cylinder 1, a connecting plate 2 is provided on one side of the drug mixing cylinder 1, a drug dosing syringe 21 is installed on one side of the top of the connecting plate 2, one side of the drug dosing syringe 21 is connected to a drug dosing tube 24, a second one-way valve 220 is installed on the drug dosing tube 24, the second one-way valve 220 can only discharge the drug in the drug dosing syringe 21 out of the drug dosing syringe 21, the drug dosing syringe 21 on one side of the drug dosing tube 24 is connected to a drug suction tube 25, the other end of the drug suction tube 25 is placed in the drug mixing cylinder 1, a first one-way valve 219 is installed in the drug suction tube 25, the first one-way valve 219 can only add the drug in the drug mixing cylinder 1 to the drug dosing syringe 21 through the drug suction tube 25, a piston 218 is slidably connected in the drug dosing syringe 21, and a connecting block 21 is installed on one side of the piston 218 6. The inner side of the connecting block 216 is rotatably connected with a connecting shaft 217, and a telescopic mechanism 22 is installed on the outer side of the connecting shaft 217. The telescopic mechanism 22 includes a screw 215 and a connecting frame 214 fixedly connected to the outer side of the connecting shaft 217. One end of the connecting frame 214 is provided with a connecting hole 223, and the connecting frame 214 is sleeved on the outer side of the screw 215 through the connecting hole 223. The outer side of the screw 215 is threadedly sleeved with two nuts 221; a servo motor 213 is installed on the top of the connecting plate 2 away from the dosing syringe 21. The driving end of the servo motor 213 is fixedly connected to a driving disk 23, and an adjusting mechanism is arranged on the driving disk 23. The adjusting mechanism includes an adjusting slot 210 provided on the driving disk 23, and a sliding connection is arranged in the adjusting slot 210. An adjusting block 211 is connected, and a screw rod 27 is rotatably connected between the two sides of the inner cavity of the adjusting groove 210, and the adjusting block 211 is threadedly sleeved on the outer side of the screw rod 27. The adjusting block 211 is fixedly connected to the solid bottom plate, and a rotating rod 28 is installed on the fixed plate 29. One end of the connecting frame 214 is rotatably connected to the rotating rod 28. A large amount of medicine is mixed according to the proportion of the medicine in the mixing cylinder 1, and then the servo motor 213 is started to drive the driving disk 23 to rotate. Since one end of the connecting frame 214 is rotatably connected to the rotating rod 28, and one end of the screw rod 215 is rotatably connected to the inner side of the connecting block 216 through the connecting shaft 217, the piston 218 can be driven to reciprocate in the dosing syringe 21, thereby cooperating with the suction tube 25, the second one-way valve 220 and The first one-way valve 219 can absorb the medicine in the mixing cartridge 1 into the dosing syringe 21, and then add it to the treatment tank through the dosing tube 24, so that the driving disk 23 can add a certain amount of medicine to the treatment tank by rotating one circle. It is not necessary for personnel to manually re-add medicine every time sewage treatment is performed, which improves work efficiency and is convenient for people to use. By screwing the nut 221, the length of the connection between the connecting frame 214 and the screw 215 can be adjusted. At the same time, by screwing the screw 27, the connection between the rotating rod 28 and the connecting frame 214 can be adjusted to different positions on the driving disk 23.
