A method for using a quantitative feeding method of a sludge dewatering conditioner preparation device, based on the sludge dewatering conditioner preparation device according to any one of claims 1 to 9, characterized in that: include: S1: adjusting the proportions of materials required for preparing the sludge dewatering conditioner, and packaging them in a plurality of placement cylinders (202d), which are then stacked on the bracket (202b); S2: activating the hydraulic rod (201b), coordinating the hinge connection between the hydraulic rod and the fixed block (201a) and the hinge connection between the hydraulic rod and the connecting frame (201c), and coordinating the cross hinge connection between the connecting frame (201c), the base frame (201d), and the plurality of connecting plates (202a), so that the bracket (202b) and the base frame (201d) rotate alternately; S3: Cooperating with the limiting frame (202c), the plurality of placement cylinders (202d) are sequentially and orderly dropped downward into the interior of the preparation tank (102). After the addition is completed, the placement cylinders (202d) are dropped onto the top of the placement plate (202e). The liquid is flushed, so that the materials inside the placement cylinders (202d) pass through the filter screen and are mixed to the bottom of the preparation tank (102) for stirring; S4: After the materials are put into the preparation tank (102) in equal proportions, the motor (301a) is started to rotate the rotating rod (301b), and the screen (302a) inside the device plate (301c) cooperates with the stirring plate (302b) to stir and mix the materials on a large scale, while the scraping plate (302c) at the bottom scrapes the materials that have settled to the bottom and remixes them; S5: Start the second motor (401b) to deflect the monitoring screen (401c) to a suitable position angle, connect it to the pH detector inside the preparation tank (102) through the network terminal, and quickly monitor the pH and mixing degree inside the tank online; S6: Observe through the observation window (103). After the mixing is completed, open the control valve (402a) to allow the discharge pipe (402b) to quickly discharge the sludge dewatering conditioner. S7: During subsequent maintenance work, the rotary block (2034) is rotated, and the clamping rod (2032) is grasped and moved upward, so that the rotary block (2034) leaves the bottom of the fixed plate (2031) and no longer blocks the placement plate (202e); S8: Grab the hidden handle to move the placement plate (202e) out of the preparation tank (102), and recycle and clean the multiple placement cylinders (202d) for secondary use.
