[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the top of the stirring drum is equipped with two No. 3 speed-regulating motors, and the output shaft of each No. 3 speed-regulating motor is equipped with a rotating column.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the No. 3 speed-regulating motor can rotate the rotating column.
[0010] Furthermore, each of the rotating columns has multiple stirring blades arranged in a linear, equidistant array on both sides.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the rotating column can rotate with the stirring blades, and the stirring blades can make the poured medicine liquid and sewage fully mixed evenly.
[0012] Furthermore, a feed inlet is provided at the top of the mixing drum near one side.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the feed inlet makes it easier to pour in materials.
[0014] Furthermore, four support plates are fixed to the bottom of the stirring tank.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the support plate can support the bottom of the mixing tank.
[0016] Furthermore, each of the four support plates is provided with a base plate at its bottom.
