[0052] The use process of the present application is as follows: when the present application is used, the device is placed beside the sewage treatment equipment, so that the dosing pipe one 8 and the dosing two are located at the medicine inlet of the sewage treatment equipment, and since the two dosing mechanisms have the same use method, a single dosing assembly is taken as an example;

[0053] When used, the on-off valve one 6 is opened, then the liquid medicine is added to the storage box one 2 through the liquid adding pipe 5, and the powder medicine is added to the storage box two 3 through the hopper 7, and then the on-off valve one 6 is closed;

[0054] When the liquid medicine needs to be added, the on-off valve two 29 and the on-off valve three 31 are opened, and the on-off valve four 48 is closed, then the motor 17 is controlled to rotate forward, the motor 17 rotates forward to drive the rotating shaft two 18 to rotate, since the bevel gear one 32 is connected with the rotating shaft two 18 through a one-way bearing, so the bevel gear one 32 does not rotate when the motor 17 rotates forward, the rotating shaft two 18 rotates to drive the rotating shaft three 34 to rotate, the rotating shaft three 34 rotates to drive the rotating disc 22 to rotate, since the pull plate 25 is connected with the connecting rod one 23 and the connecting rod two 24 through a bearing, so the rotating disc 22 can rotate under the action of the pull plate 25, so that the pull rod 21 and the piston one 20 can move up and down continuously, wherein the piston one 20 moves upward to make the air outside enter the box one 19 under the action of the pipeline two 27 and the one-way valve two 30, and the piston one 20 moves downward to make the air in the box one 19 enter the storage box one 2 under the action of the pipeline one 26 and the one-way valve one 28, so that the piston one 20 continuously moves up and down to continuously fill the air into the storage box one 2, so that the pressure in the storage box one 2 becomes larger, when the pressure in the storage box one 2 is greater than the threshold value of the safety valve 9, the safety valve 9 is automatically opened, after being opened, the liquid medicine in the storage box one 2 can enter the sewage treatment equipment through the dosing pipe one 8, when the pressure in the storage box one 2 recovers, the safety valve 9 is automatically closed, so that the liquid medicine can be continuously added to the sewage treatment equipment;

[0055] When the powder medicine needs to be added, the on-off valve two 29 and the on-off valve three 31 are closed, the on-off valve four 48 is opened, and then the control motor 17 is reversed, so that the bevel gear one 32 can rotate, the bevel gear one 32 drives the bevel gear two 33 to rotate, the bevel gear two 33 drives the rotating shaft one 14 to rotate, and the rotating shaft one 14 drives the spiral blade 15 to rotate, so that the powder medicine can be continuously transported downward along the medicine adding pipe two 10, and the powder medicine can extrude the sealing plug 52 to move downward while the spring 55 is compressed, and when the sealing plug 52 moves downward, the powder medicine can fall through the gap between the sealing seat 51 and the sealing plug 52 into the sewage treatment equipment, so that the powder medicine can be added to the sewage treatment equipment, and when no powder medicine is added, the powder medicine cannot move downward, so that the sealing plug 52 cannot be extruded, so that the sealing plug 52 can move upward and contact the sealing seat 51 under the action of the spring 55, so that the residual medicine in the medicine adding pipe two 10 cannot continue to fall;

[0056] When the motor 17 is reversed to rotate the rotating shaft two 18, the rotating shaft three 34 and the rotating disc 22 can also rotate, so that the pull rod 21 and the piston one 20 also move up and down continuously, and then the piston one 20 moves up and down to make the air in the box one 19 and the two box twos 41 flow back and forth under the action of the communication pipe two 47 and the communication pipe one 46, so that the two pistons two 42, the two moving rods 44 and the moving plate 43 move up and down continuously, and the moving plate 43 moves up and down to make the sleeve two 36, the three stirring rings 37 and the dispersing frame 38 move up and down continuously, so that the powder medicine can be stirred, so that the powder medicine is prevented from being accumulated for a long time to form lumps, so that the spiral blade 15 can normally transport the powder medicine, and then the powder medicine can be normally added, wherein two spiral strips 39 are designed on the sleeve one 35, two spiral grooves 40 are designed on the inner wall of the sleeve two 36, and the two spiral strips 39 are embedded in the two spiral grooves 40, so that the sleeve two 36, the three stirring rings 37 and the dispersing frame 38 also rotate reciprocatingly under the action of the spiral strips 39 and the spiral grooves 40 when they move up and down, so that the stirring effect on the powder medicine is increased to prevent the powder medicine from forming lumps;

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

[0058] The above merely is the preferred embodiment of the present application, any skilled person in the art can modify the present application by using the above-mentioned technical solutions or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement according to the technical solutions of the present application is within the scope of the present application.
