[0009] According to the above technical solution, the medicine pounder contacts the inner wall of the medicine storage tank, and a discharge port is provided at the bottom of the medicine storage tank, through which the medicine is introduced into the medicine spreading device.

[0010] According to the above technical solution, the medicine spreading device includes: a medicine spreading trough, a rotating rod and a ring.

[0016] The present invention provides a sewage treatment dosing and stirring device. It has the following beneficial effects: (1) In the present invention, the rotation of the shaft drives the connecting rod to rotate, and the rotation of the connecting rod drives the medicine pounder to rotate. The rotation of the medicine pounder will crush the agglomerated medicine that cannot flow out from the medicine outlet, preventing the agglomerated medicine from being fully mixed with sewage, thereby improving work efficiency.

The rotation of the medicine pounder will hit the protrusion, and the protrusion will vibrate after being hit, so that the agglomerated medicine accumulated at the medicine outlet will be spread out after being vibrated, making it easier for the medicine pounder to crush, thereby improving the practicality of the device.

[0017] (2) In the present invention, the rotation of the shaft drives the rotating rod to rotate. When a sufficient rotation speed is reached, centrifugal force is generated, causing the rotating rod to open the ring. The medicine in the medicine spreading trough is sprinkled out through the medicine outlet under the action of centrifugal force, so that the medicine can be evenly sprinkled over a larger range, thereby improving the fusion efficiency of the medicine and sewage.

When the rotating rod moves toward the top, the rotating rod will drive the dredging rod to rotate, thereby dredging the medicine outlet, thereby preventing excessive accumulation of medicine in the medicine outlet from causing the crushed medicine to be unable to flow into the medicine spreading trough, thereby improving the stability of the device.

[0018] (3) In this invention, the rotation of the shaft drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the stirring plate to rotate. The rotation of the stirring plate will fully stir the sewage and the medicine, thereby improving the degree of mixing between the medicine and the sewage. The rotation of the reciprocating screw drives the sleeve to move back and forth, and the movement of the sleeve drives the movement of the dredging plate, so that when the sewage and the medicine are stirred, they will not only rotate and stir, but also stir up and down, further improving the degree of mixing between the medicine and the sewage and ensuring work efficiency.
