[0050] Among them, in order to achieve the purpose of preventing the remaining medicine in the second dosing pipe 10 from continuing to fall, the present device adopts the following technical solutions: The anti-falling component includes a sealing seat 51. The sealing seat 51 is fixedly connected inside the second dosing pipe 10. A sealing plug 52 is arranged in the sealing seat 51.

By designing the anti-falling component, it can play an automatic cut-off function when adding powder medicine, and can prevent the remaining medicine in the second dosing pipe 10 from continuing to fall;

[0051] Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solution: The first rotating shaft 14 is connected to the support rod 13 and the first sleeve 35 through a sealed bearing, and the second rotating shaft 18 is connected to the connecting rod 16 through a bearing. The connection through the sealed bearing can not only reduce wear but also prevent materials from entering the bearing interior.

[0052] The usage process of the present invention is as follows: When using the present invention, place the device beside the sewage treatment equipment so that the first dosing pipe 8 and the second dosing pipe are located at the medicine inlet of the sewage treatment equipment. Since the usage methods of the two dosing mechanisms are the same, take a single dosing component as an example;

[0053] When in use, open the first switching valve 6, then add liquid medicine into the first storage tank 2 through the liquid adding pipe 5, and add powder medicine into the second storage tank 3 through the feeding hopper 7, and then close the first switching valve 6;

[0054] When liquid medicine needs to be added, open the second switching valve 29 and the third switching valve 31, and close the fourth switching valve 48. Then control the motor 17 to rotate forward. The forward rotation of the motor 17 drives the second rotating shaft 18 to rotate. Since the first bevel gear 32 is connected to the second rotating shaft 18 through a one-way bearing, the first bevel gear 32 does not rotate when the motor 17 rotates forward. The rotation of the second rotating shaft 18 drives the third rotating shaft 34 to rotate, and the rotation of the third rotating shaft 34 drives the turntable 22 to rotate. Since the pull plate 25 is connected to the first connecting rod 23 and the second connecting rod 24 through bearings and can move, the rotation of the turntable 22 under the action of the pull plate 25 can make the pull rod 21 and the first piston 20 move up and down continuously. Among them, under the action of the second pipeline 27 and the second check valve 30, when the first piston 20 moves upward, the outside air can enter the first box body 19, and under the action of the first pipeline 26 and the first check valve 28, when the first piston 20 moves downward, the air in the first box body 19 can enter the first storage tank 2. In this way, by cycling, the first piston 20 moves up and down continuously, and air can be continuously filled into the first storage tank 2, so that the pressure in the first storage tank 2 becomes larger. When the pressure in the first storage tank 2 is greater than the threshold value of the safety valve 9, the safety valve 9 will automatically open. After opening, the liquid medicine in the first storage tank 2 can enter the sewage treatment equipment through the first dosing pipe 8. When the pressure in the first storage tank 2 is restored, the safety valve 9 automatically closes. By cycling in this way, liquid medicine can be continuously added to the sewage treatment equipment;

[0055] When adding powder drugs, close the second switching valve 29 and the third switching valve 31, open the fourth switching valve 48, and then control the motor 17 to reverse. In this way, the first bevel gear 32 can rotate. The rotation of the first bevel gear 32 drives the rotation of the second bevel gear 33. The rotation of the second bevel gear 33 drives the rotation of the first rotating shaft 14. The rotation of the first rotating shaft 14 drives the rotation of the spiral blade 15. In this way, the powder drugs can be continuously conveyed downward along the second medicine adding pipe 10. When being conveyed, the powder drugs will squeeze the sealing plug 52 to move it downward. At the same time, the spring 55 is compressed. When the sealing plug 52 moves downward, the powder drugs can fall into the sewage treatment equipment through the gap between the sealing seat 51 and the sealing plug 52. In this way, adding powder drugs to the sewage treatment equipment can be realized. When not adding, the powder drugs cannot move downward, so that the sealing plug 52 will not be squeezed. In this way, under the action of the spring 55 rebounding, the sealing plug 52 can move upward to contact with the sealing seat 51, which can prevent the residual drugs in the second medicine adding pipe 10 from continuing to fall;

[0056] When the motor 17 reverses to rotate the second rotating shaft 18, the third rotating shaft 34 and the turntable 22 can also rotate. In this way, the pull rod 21 and the first piston 20 also continuously move up and down. Then, under the action of the second connecting pipe 47 and the first connecting pipe 46, the up and down movement of the first piston 20 can make the air in the first box body 19 and the two second box bodies 41 flow back and forth. Then, the two second pistons 42, the two moving rods 44 and the moving plate 43 can continuously move up and down. The up and down movement of the moving plate 43 can make the second sleeve 36, the three dial rings 37 and the dispersion frame 38 continuously move up and down. In this way, the powder drugs can be turned over, so as to avoid the powder drugs from accumulating together and caking for a long time, so as to ensure the normal conveying of the powder drugs by the spiral blade 15, and further ensure the normal progress of the medicine adding work of the powder drugs. Two spiral strips 39 are designed on the first sleeve 35, and two spiral grooves 40 are designed on the inner wall of the second sleeve 36. And the two spiral strips 39 are embedded in the two spiral grooves 40. In this way, under the action of the spiral strips 39 and the spiral grooves 40, when the second sleeve 36, the three dial rings 37 and the dispersion frame 38 move up and down, they will also rotate reciprocally. In this way, the turning effect on the powder drugs can be increased to avoid the phenomenon of caking of the powder drugs;

[0057] In actual use, acidic drugs in liquid and powder form can be added to one medicine adding mechanism, and alkaline drugs in liquid and powder form can be added to another medicine adding mechanism. Then, according to the above steps, acidic drugs in liquid and powder form and alkaline drugs in liquid and powder form can be added to the sewage treatment equipment.

[0058] The above are only the preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection required by the present invention.
