The advantages of the invention are illustrated by the following:

before the work begins, 2 sets of 15m settling ponds are arranged near the settling pond 1³The coal slime water treatment equipment and the matched dosing facility are characterized in that the boosted coal-containing wastewater is treated in a centralized way, the treatment equipment is internally provided with an inclined pipe and a filter material, the dosing, clarification and filtering processes are adopted, and the measures of mud discharge, backwashing and the like are combined to effectively reduce the turbidity in the coal-containing wastewater, when the equipment normally operates for a period of time and the resistance of a filter layer is increased to cause the water pressure difference in and out to reach a set value, a backwashing signal is sent by a pressure difference transmitter to carry out backwashing by linking an electric valve for water inlet and outlet and a backwashing water pump, the clarification and mud discharge can be carried out at regular time according to the debugging and operating experience, the discharged mud water flows back into a coal slime pool automatically,the matched dosing facility of the coal water treatment equipment comprises two medicaments of flocculating powder and coagulation aid powder.

When the medicine powder feeding device works, the cross section of the side wall of the medicine inlet 12 is arranged in an inclined structure, the medicine powder is conveyed downwards when the opening end of the medicine inlet 12 is opened due to the action of gravity, the opening end of the medicine receiving notch 24 is larger than the opening length of the bottom outlet of the medicine inlet 12, the medicine powder can be stably horizontally conveyed into the medicine receiving notch 24 close to the end of the medicine inlet 12, the medicine powder is not fully accumulated in the medicine receiving notch 24 at the moment, the buckling piece 43 is buckled in the fixing slot 4 in a buckling mode, the buckling spring 42 is always kept in a compression state, the elastic force is larger than the thrust generated by the gravity accumulation of the medicine powder in the medicine receiving notch 24 at the moment, and the outer ring barrel 22 does not rotate;

when the medicine powder is fully accumulated in the medicine receiving notch 24, the medicine powder accumulation gravity is larger than the elastic force of the buckle spring 42 at the moment, the lower end section of the buckle piece 43 is arranged in an inclined plane structure, the lower end section of the fixing slot 4 is arranged in an inclined structure, the buckle piece 43 slowly slides out under the action of the mass pushing force of the medicine powder in the medicine receiving notch 24 and retracts into the buckle piece storage groove 41 under the action of rotation, the medicine powder gravity continuously pushes the medicine receiving notch 24 in the horizontal direction to rotate clockwise at the moment, and the side wall of the next medicine receiving notch 24 is tightly attached to the opening end of the medicine inlet 12, so that the medicine powder continuously conveyed by the opening end of the medicine inlet 12 cannot be continuously received by the medicine receiving notch 24 fully filled with the medicine powder, and the function of controlling the amount of the medicine powder is achieved;

when rotating to have a small amount of partial powder to spill, outer lane barrel 22 stall, and the medicine notch 24 that connects that piles up powder at this moment has rotated 90 from the horizontal position approximation originally, but powder still has most to spill at this moment, waits for the third to connect the inside powder of medicine notch 24 and fills up, and the first notch 24 that connects that fills up powder is located approximate horizontal position, and the notch end of the first notch 24 that connects the medicine at this moment is towards the lower extreme.

From what is described herein, it can be seen that: according to the invention, through the matching action of the medicine inlet 12, the outer ring cylinder 22, the inner ring cylinder 21, the medicine receiving notch 24, the buckle assembly and the limiting assembly, the automatic medicine powder adding function is realized by utilizing the thrust action of gravity conversion of medicine powder, and in the process of adding the medicine powder in the sedimentation tank 1, the rotating effect is realized by utilizing fixed gravity, so that the quantitative medicine adding function is achieved, in addition, through the matching action of the bearing rotating plate 23, the medicine receiving notch 24 and the medicine inlet 12, when the outer ring cylinder 22 rotates, the function of cleaning the medicine powder at the opening end of the medicine inlet 12 is realized, and the blockage condition caused by long-term medicine powder accumulation at the opening end is avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
