In the process that the connecting ring 9 drives the convex filter screen 17 to rotate, the trapezoid blocks 32 can be placed in the filter residue collecting tank, the filter residues in the tank are pushed through extrusion fit of the sponge cushion 35 and the filter residue collecting tank, the effect that the filter residues are automatically concentrated and accumulated is achieved, later cleaning is convenient, and the blocking preventing effect can be achieved.
The lifting plate 7 is lowered to a certain height by starting the screw motor 11, so that the suspension block 40 is suspended in the wastewater in the sedimentation tank 2, then the water suction pump 36 is started, the precipitated wastewater enters the water suction hose 37 through the water suction hard pipe 38, and then flows out of the water outlet hose 43; at this time, under the action of gravity of the counterweight ring 41, the suspension block 40 descends synchronously with the water level, and the slide rod 39 drives the nut ring 42 to descend simultaneously, before that, the descending height of the suspension block 40 can be controlled by adjusting the height of the nut ring 42, and the height setting adjustment is performed by matching with the scale value 44, so that the height of the residual water level in the sedimentation tank 2 can be reserved, and excessive extraction is prevented; after the extraction of wastewater in the sedimentation tank is completed, the screw motor 11 is started again to drive the lifting plate 7 to move upwards, at the moment, the lifting plate 7 can drive the sliding rod 39 to move upwards through the nut ring 42, and simultaneously, the suspension block 40 is driven to move upwards through the counterweight ring 41, when the lifting plate 7 moves to the highest position, the screw motor 11 stops working, at the moment, the suspension block 40 can be positioned above the sedimentation tank 2, the servo motor 8 is started, the rotating column 5 is driven to rotate, the reaction tank 1 is rotated to the position right above the sedimentation tank 2, and the water pumping mechanism is rotated to the other side to wait for the next use. The control valve 45 is opened, and the wastewater after completion of the coagulation reaction in the reaction tank 1 can be placed in the sedimentation tank 2, and the sedimentation process can be continued. The repeated operation can not only improve the working efficiency, but also adjust the height of pumping water each time by setting the height of the suspension block 40 downwards, without cleaning the sedimentation tank 2 each time, and can control the quality of pumping water and reduce the pumping of sediment; meanwhile, the equipment is reasonable in layout, simple to operate and flexible and convenient to use.
However, as well known to those skilled in the art, the working principles and wiring methods of the servo motor 8, the screw motor 11, the driving motor 22, and the water pump 36 are well known, which are all conventional means or common general knowledge, and will not be described herein in detail, and any choice can be made by those skilled in the art according to their needs or convenience.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present invention, which is intended to be covered by the claims of the present invention.
