[0029] When in use, before the sewage reacts with the flocculant, the guide float 3011 can be pulled so that the guide float 3011 drives the filter ball 3014 to move upward, so that the floating block 3013 is close to the cover plate 102, so as to prevent the solid-liquid separation component 301 from affecting the high-efficiency stirring mechanism 2, and then the locking bolt 302 is tightened to fix the guide float 3011. After the reaction is completed, the locking bolt 302 can be loosened to make the guide float 3011 fall under the action of gravity. At this time, the floating block 3013 floats on the surface of the supernatant water after the reaction, and then the discharge pipe 103 can be connected through the water pump to enable the water pump to extract the supernatant water.

At this time, the row of control keys 101 can be operated to control the electric push rod 4014 to work, and the pressing plate 4013 is pushed under the action of the electric push rod 4014 to squeeze the flocculated sediment and squeeze out most of the water contained in the flocculated sediment. Since the pressing plate 4013 is an L-shaped structure, the flocculated sediment can be prevented from falling to the other side of the pressing plate 4013. Subsequently, the squeezed flocculated sediment and water can be discharged through the discharge pipe 4011 respectively, so as to realize the squeezing function of the flocculation equipment on the flocculated sediment.

[0032] Working principle: when in use, firstly, the sewage and the flocculant are guided to the inside of the flocculation tank 1 through the water inlet pipe on the surface of the cover plate 102, and then the control row of keys 101 is operated to make the control row of keys 101 control the driving motor 2015 to work, and the middle bevel gear 2014 is driven to rotate under the action of the driving motor 2015, and the middle bevel gear 2014 drives the inner bevel gear 2012 and the outer bevel gear 2016 to rotate synchronously under the meshing action of the inner bevel gear 2012 and the outer bevel gear 2016 respectively, and the inner bevel gear 2012 and the outer bevel gear 2016 rotate in opposite directions, at this time, the inner bevel gear 2012 drives the inner stirring frame 2013 to rotate synchronously, and the outer bevel gear 2016 drives the outer stirring frame 2011 to rotate synchronously, so that the outer stirring frame 2011 and the inner stirring frame 2013 rotate in opposite directions, so that the sewage and the flocculant are quickly and fully mixed, so as to realize the efficient stirring function of the flocculation equipment, thereby improving the working efficiency of the flocculation equipment when in use.

[0033] Before the sewage reacts with the flocculant, the guide float 3011 can be pulled so that the guide float 3011 drives the filter ball 3014 to move upward, so that the floating block 3013 is close to the cover plate 102, so as to prevent the solid-liquid separation component 301 from affecting the high-efficiency stirring mechanism 2, and then the locking bolt 302 is tightened to fix the guide float 3011. After the reaction is completed, the locking bolt 302 can be loosened to make the guide float 3011 fall under the action of gravity. At this time, the floating block 3013 floats on the surface of the supernatant water after the reaction, and then the discharge pipe 103 can be connected through the water pump to enable the water pump to extract the supernatant water. At this time, the supernatant water enters the interior of the hose 3012 through the filter ball 3014. At the same time, the floating block 3013 gradually decreases as the supernatant water decreases, which facilitates the extraction of the filter ball 3014, so as to realize the function of the flocculation equipment to facilitate the extraction of supernatant water, thereby improving the convenience of the flocculation equipment during solid-liquid separation.

[0034] After the extraction of the upper clear water is completed, the control valve 403 can be opened by controlling the control key 101 to discharge the flocculated sediment to the surface of the filter screen 4012 inside the squeezing box 402. At this time, the control key 101 can be operated to control the control key 101 to control the electric push rod 4014 to work, and the pressure plate 4013 is pushed under the action of the electric push rod 4014 to squeeze the flocculated sediment and squeeze out most of the water contained in the flocculated sediment. Since the pressure plate 4013 is an L-shaped structure, the flocculated sediment can be prevented from falling to the other side of the pressure plate 4013. Subsequently, the squeezed flocculated sediment and water can be discharged respectively through the discharge pipe 4011 to realize the squeezing function of the flocculation equipment on the flocculated sediment, thereby reducing the water content of the flocculation sediment when the flocculation equipment is in use, and finally completing the use of the flocculation equipment.
