[0020] The technical solution provided by this application may include the following beneficial effects:

[0021] The device differentiates between liquid medicaments and solid medicaments and places them in different medicine boxes respectively. When medicine needs to be administered, for liquid medicaments, the liquid dosing pump is opened to pump the medicaments in the liquid medicine box into the dosing box first. Before the medicaments are pumped in, clear water that needs to be set is pumped into the dosing box through control, and then the medicaments are pumped into the dosing box to be mixed with the clear water to obtain a uniform mixed medicament, and then it is transported into the corresponding sewage treatment tank through a pipeline connected to the medicine outlet. For liquid medicaments, they are first incremented by the clear water in the dosing box, but their concentration does not change during the overall sewage treatment process. In this way, the volume of the medicine-water mixture is increased, the diffusion area in the sewage is larger, the diffusion amount per unit time is larger, and the mixing treatment is more uniform. For solid medicaments, in the same way, they first enter the dosing box, are mixed evenly and then administered, so that the diffusion area of the solid medicaments in the sewage is increased, and the reaction can be carried out more evenly. At the same time, the technical solution of the present application can load multiple medicaments at the same time, and corresponding programs can be preset in the controller for individual dosing or mixed dosing, with more selectivity. At the same time, the amount of medicine input can be accurately measured through the first liquid level sensor, weight sensor, etc., so as to achieve accurate and automatic dosing.

[0033] As Figure 1 shown, an automatic chemical dosing device for sewage treatment includes:

[0034] Medicine dispensing box 1, the medicine dispensing box 1 is a cylindrical container for accommodating medicine. The bottom of the medicine dispensing box 1 is configured with a first medicine outlet 11, the middle part is configured with a water inlet 12 connected to a water source, the inner wall is configured with an annular platform 13, and the top is configured with a box cover 14 covering the entire medicine dispensing box 1;

[0035] Annular plate 2, the annular plate 2 is set as an annular plate, and a plurality of first through holes 21 are configured on the annular plate 2. A second through hole 22 is configured in the middle part thereof. The annular plate 2 is mainly used as a supporting component for installing other components subsequently;

[0038] Weight sensor 5;

[0039] Solid medicine adding switch 7;

[0040] First liquid level sensor 10;

[0041] Controller;

[0042] Among them, the annular plate 2 is arranged on the annular platform 13, the liquid medicine box 3 and the solid medicine box 4 are arranged on the annular plate 2, and the liquid medicine adding pump 31 and the second medicine outlet 41 are located in the first through holes 21; a first liquid level sensor 10 is arranged at the bottom of the medicine dispensing box 1 and connected to the controller, a solid medicine adding switch 7 is arranged at the second medicine outlet 41 and electrically connected to the controller, a weight sensor 5 is arranged on the annular plate 2 below the solid medicine box 4 and connected to the controller, and the liquid medicine adding pump 31 is electrically connected to the controller; a stirring motor 9 is arranged on the box cover 14, a stirring shaft 91 is connected to the rotating shaft of the stirring motor 9, the stirring shaft 91 passes through the second through hole 22 and a stirring paddle 92 is connected thereto, and the stirring paddle 92 is located in the middle and lower part of the medicine dispensing box 1.

[0043] This device differentiates between liquid medicine and solid medicine and places them in different medicine boxes respectively. When medicine needs to be administered, for liquid medicine, the liquid medicine adding pump 31 is opened to pump the medicine in the liquid medicine box 3 into the medicine feeding box 1 first. Before the medicine is pumped in, the clear water to be set is first controlled to enter the medicine feeding box 1 through the pump, and then the medicine is pumped into the medicine feeding box 1 to be mixed with the clear water to obtain a uniform mixed medicine, and then it is transported into the corresponding sewage treatment tank through the pipeline connected to the first medicine outlet 11. For liquid medicine, it is first incremented by the clear water in the medicine feeding box 1, but its concentration does not change during the overall sewage treatment process. In this way, the volume of the medicine-water mixture is increased, the diffusion area in the sewage is larger, the diffusion amount per unit time is larger, and the mixing treatment is more uniform. For solid medicine, in the same way, it first enters the medicine feeding box 1, is mixed evenly and then administered, so that the diffusion area of the solid medicine in the sewage is increased and the reaction can be carried out more evenly. At the same time, the technical solution of this application can load multiple kinds of medicines at the same time, and corresponding programs can be preset in the controller for separate medicine administration or mixed medicine administration, with more selectivity. At the same time, it can accurately measure the amount of medicine input through the first liquid level sensor 10, weight sensor 5, etc., so as to achieve accurate and automatic medicine administration.

[0044] In one embodiment, in order to further control and measure the amount of medicine administered, a solenoid valve is provided at the water inlet 12 and connected to the controller; a solenoid valve is provided at the first medicine outlet 11 and connected to the controller, and a second liquid level sensor is provided at the bottom of the liquid medicine box 3 and connected to the controller.

[0046] In one embodiment, as Figure 2 shown, the dosing control of the solid medicine is realized through the solid medicine adding switch 7. Specifically, the solid medicine adding switch 7 includes a fixed medicine adding motor 6, a connecting rod 71, an arc plate 72, and a medicine outlet hole 73;

[0047] Among them, the fixed medicine adding motor 6 is embedded in the bottom inside of the annular plate 2, one end of the connecting rod 71 is fixedly connected to the rotating shaft of the fixed medicine adding motor 6, the arc plate 72 is connected to one end of the connecting rod 71, and the medicine outlet hole 73 is provided in the middle of the arc plate 72 and abuts against the second medicine outlet 41. In this way, the dosing of the solid medicine is accurately controlled through the combination of the solid medicine adding switch 7 and the weight sensor 5.

[0048] In one embodiment, since the connecting rod 71 is a cantilever beam, in order to prevent the connecting rod 71 from jamming during long-term operation or when a large piece of medicine gets stuck, a U-shaped clamp 74 is provided below the connecting rod 71. The bottom of the U-shaped clamp 74 is arranged parallel to the bottom of the annular plate 2, and both sides are fixedly connected to the bottom of the annular plate 2. In this way, not only the swinging angle of the connecting rod 71 is restricted, but also the arc-shaped plate 72 can be closely attached to the bottom of the second medicine outlet 41 through the bottom of the U-shaped clamp 74.

[0049] In one embodiment, a medicine adding port 15 is provided on the box cover 14 to facilitate the addition of medicine.

[0050] Finally, it should also be noted that in this text, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] The units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place, or may be distributed to multiple network units. Some or all of the units can be selected according to actual needs to achieve the purpose of the solution of this embodiment.
