The drug delivery pipe 13 of the drug feeding device is arranged on the baffle, the lower end of the drug delivery pipe is provided with a drug feeding assembly 14, and the drug feeding assembly is arranged corresponding to the water passing channel. The baffle is used as the installation foundation of the medicament delivery pipe, and plays a role in guiding the flowing direction of the water body, so that the water body passes through the position (water passing channel) of the medicament feeding assembly, and the mixing effect of the medicament during feeding is improved.

Generally, above-mentioned medicament conveyer pipe passes through fixed subassembly to be fixed and separates to keep off different in drainage pond one side, and fixed subassembly can generally adopt the mounting that commonly uses such as clamp, because the fixed of pipeline belongs to conventional technical content, consequently, no longer gives unnecessary details here.
