Flocculants can effectively aggregate and precipitate suspended matter in the wastewater to form floccules, which is convenient for subsequent solid-liquid separation treatment. At present, mine wastewater is usually introduced into a sedimentation tank first, and then an appropriate amount of flocculant is added to the sedimentation tank, and mixed with the stirring equipment in the tank. However, the flocculant is not easy to be evenly distributed at multiple points during the addition process, and the stirring equipment is fixed in position and cannot achieve comprehensive and uniform stirring, which will prolong the coagulation and sedimentation time, thereby affecting the efficiency of subsequent solid-liquid separation.

A rectangular opening is provided on the top of the processing box 1 for the hollow plate 3 to slide, and a slide groove is provided on the side wall of the rectangular opening for the guide block 16 to slide, so that the hollow plate 3 can be guided and slid along the length direction of the processing box 1.

[0021] A driving assembly for driving the hollow plate 3 to reciprocate is installed on the shell cover 2, and the driving assembly includes a motor 17 installed on the outer wall of one end of the shell cover 2, and a reciprocating screw extending into the shell cover 2 is installed at the output end of the motor 17. A screw slider 18 threadedly connected to the reciprocating screw is installed on the top of the hollow plate 3, so that when the motor 17 drives the reciprocating screw to rotate, the screw slider 18 drives the hollow plate 3 to reciprocate.

[0022] A plurality of rotating shafts 4 are rotatably mounted on the hollow plate 3, a gear 5 is mounted on the top of the rotating shaft 4, and a rack 6 meshing with the gear 5 is mounted on the upper surface of the inner part of the shell cover 2, so that the rotating shaft 4 can be driven to rotate when the hollow plate 3 moves back and forth. The rotating shaft 4 runs through the hollow plate 3. In this embodiment, in order to ensure the sealing of the rotating connection, the rotating shaft 4 and the hollow plate 3 are rotatably connected through a sealed bearing, and a stirring member 7 extending into the processing box 1 is installed at the bottom end of the rotating shaft 4, so as to drive the stirring member 7 to rotate during the reciprocating movement to achieve comprehensive and uniform stirring.

[0023] An inverted L-shaped tube 8 is connected to the top of the hollow plate 3, and a plurality of liquid distribution holes are provided at the bottom of the hollow plate 3.
