Technical Field

[0001] The utility model relates to the technical field of drug dosing devices, and specifically to a drug dosing device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] When purifying sewage, a dosing device is often used. In actual use, although the existing dosing device can achieve the function of purifying sewage, the existing dosing device generally does not have the function of adjusting the dosing direction, which will cause the dosing device to dosing in one direction, while the waters in other directions can only achieve the purpose of sewage purification through drug diffusion. This method increases the time of sewage purification and cannot purify sewage quickly, so it needs to be improved. Utility Model Content

[0027] A bottom plate 1, a toothed disc 2 is movably sleeved inside the bottom plate 1, the outer surface of the toothed disc 2 is rough, a water pump 3 is fixedly connected to the top of the toothed disc 2, a liquid discharge pipe 4 is fixedly connected to the top of the water pump 3, and a liquid extraction pipe 5 is fixedly connected to the right side of the water pump 3;

[0028] A rotating mechanism, the rotating mechanism is arranged on the top of the bottom plate 1;

[0029] Among them, the rotating mechanism includes a driving motor 6, the bottom of the driving motor 6 is fixedly connected to the top of the base plate 1, the other end of the output shaft of the driving motor 6 is fixedly sleeved with a rotating shaft 7, the outer surface of the rotating shaft 7 is fixedly sleeved with a gear 8, the outer surface of the gear 8 is meshed with the outer surface of the gear plate 2, and the gear 8 is meshed with the gear plate 2 to drive the gear plate 2 to rotate as a whole.

[0030] When the driving motor 6 is running, the rotating shaft 7 will drive the gear 8 to rotate, and then the gear 8 will mesh with the toothed disc 2 and drive the toothed disc 2 to rotate as a whole, thereby causing the discharge pipe 4 to rotate, thereby achieving the purpose of automatically adjusting the medication direction of the discharge pipe 4.

[0031] Among them, the top of the toothed disc 2 is fixedly connected to a mixing box 9 located behind the water pump 3, and a valve 10 is fixedly installed on the bottom of the left side of the mixing box 9. The left side of the valve 10 is fixedly connected to the right side of the liquid extraction pipe 5.

[0032] Opening the valve 10 allows the liquid extraction pipe 5 to extract the dosing solution inside the stirring box 9 .

[0033] Among them, a stirring motor 11 is fixedly connected to the middle of the top of the stirring box 9, and a stirring shaft 12 is fixedly sleeved on the other end of the output shaft of the stirring motor 11. The bottom of the stirring shaft 12 passes through the stirring box 9 and extends to the interior of the stirring box 9 and is fixedly connected with a stirring blade 13.

[0034] When the stirring motor 11 is running, the stirring shaft 12 will drive the stirring blades 13 to rotate to stir the dosing solution inside the stirring box 9.

[0035] The top of the mixing box 9 is fixedly connected with a feed port 14 located behind the mixing motor 11 , the top of the feed port 14 is hinged with a cover plate 15 , and the top of the cover plate 15 is fixedly connected with a handle 16 .

[0036] Pulling the handle 16 can drive the cover plate 15 to rotate to release the sealing effect of the feed inlet 14 .

[0037] Among them, a slide groove 17 is opened on the left side of the inner wall of the mixing box 9, and the inner surface of the slide groove 17 is movably connected with a movable block 18, and the bottom of the movable block 18 is fixedly connected with a float 19, and the bottom of the float 19 is movably connected to the bottom of the inner cavity of the mixing box 9. The top of the movable block 18 is fixedly connected with a lifting block 20, and the top of the lifting block 20 penetrates the mixing box 9 and extends to the top of the mixing box 9. The up and down movement of the lifting block 20 can understand the capacity of the dosing agent inside the mixing box 9.

[0038] When adding dosing agent into the mixing box 9, the float 19 is pushed upward by the buoyancy of the agent, thereby driving the movable block 18 and the lifting block 20 to move upward. When the agent in the mixing box 9 is used up, the float 19 moves downward under the action of gravity, thereby driving the movable block 18 and the lifting block 20 to move downward. Therefore, the capacity of the dosing agent in the mixing box 9 can be intuitively known through the up and down movement of the lifting block 20.

[0039] The top of the mixing box 9 is fixedly connected with a fixing block 21 located on the left side of the lifting block 20 , and the right side of the fixing block 21 is movably connected to the left side of the lifting block 20 .

[0042] When the pneumatic cylinder 22 is in operation, it will drive the clamping plate 23 to move to the left.

[0043] The working principle and use process of this utility model:

[0044] First, the operator opens the cover 15, and then pours the dosing agent and additives into the mixing box 9 through the feed port 14. The buoyancy of the dosing agent pushes the float 19 upward, thereby driving the movable block 18 and the lifting block 20 upward. As the lifting block 20 rises, the position of the agent in the mixing box 9 can be intuitively understood. When the addition of the agent is stopped, the pneumatic cylinder 22 is started, which will drive the clamping plate 23 to move to the left. With the cooperation of the fixed block 21 and the clamping plate 23, the lifting block 20 is clamped and fixed. Then, the stirring motor 11 is started, which will cause the stirring shaft 12 to drive the stirring The blades 13 rotate to mix the dosing agent and additives inside the mixing box 9. After the mixing is completed, the pneumatic cylinder 22 is started again to drive the clamping plate 23 to reset and release the fixing effect of the lifting block 20. At this time, the valve 10 is opened and the water pump 3 is started, which will cause the suction pipe 5 to extract the dosing agent inside the mixing box 9 and then discharge it through the discharge pipe 4. As the dosing agent inside the mixing box 9 is used, the float 19 moves downward under the action of gravity, thereby driving the movable block 18 and the lifting block 20 to move downward, so that the capacity of the dosing agent inside the mixing box 9 can be known by the up and down movement of the lifting block 20.

[0045] When the medication direction of the discharge tube 4 is changed, the drive motor 6 is started, which will cause the rotating shaft 7 to drive the gear 8 to rotate, and then the gear 8 meshes with the toothed disc 2 and drives the toothed disc 2 to rotate as a whole, thereby driving the discharge tube 4 to rotate, thereby achieving the purpose of automatically adjusting the medication direction of the discharge tube 4.
