The inside of the machine base is a cavity, an air inlet pipe is fixed on the outer wall of the machine base and communicated with the cavity in the machine base, and a blow-off pipe is arranged on the bottom surface of the machine base. The hot air enters the cavity in the base from the air inlet pipe and then enters the material chamber from the air outlet hole, so that the medicine powder on the sieve plate is pushed to roll and is mixed with the adhesive.

The implementation principle of the embodiment is as follows: the medicine powder is added into the cylinder body from the feeding pipe, and falls onto the sieve plate at the bottom end of the material chamber. At the moment, hot air is introduced into the air inlet pipe, and meanwhile, the adhesive is introduced into the spray gun. One part of the medicine powder blown up by the hot air is uniformly mixed with the adhesive to form medicine particles, the medicine particles are heavier, the medicine particles fall onto the sieve plate, and the other part of the medicine powder which is not mixed with the adhesive is blown to the filter bag assembly by the hot air and is collected in the filter bag assembly. And the negative pressure spray gun sprays adhesive against the lower end of the filter bag assembly, so that the medicine powder floating on the upper part of the filter bag assembly is mixed with the adhesive, and the medicine powder is bonded into medicine particles. The medicament particles descend into the material chamber due to their heavier weight. And stopping filling hot air into the air inlet pipe, stopping filling the adhesive into the spray gun, stopping filling the adhesive into the negative pressure nozzle, and taking out the medicine particles from the discharge pipe.

After the medicine particles are taken out of the cylinder body, the motor and the water pump are sequentially driven, the motor drives the connecting piece to rotate, and the connecting piece drives the spray head to rotate. The high pressure water enters into the shower nozzle through inlet tube and connecting piece in proper order, and the shower nozzle is rotatory to be sprayed the all directions in the cylinder body with high pressure water, and after the inner wall of cylinder body was touched to the high pressure water, the residue on the inner wall of cylinder body was washed, and sewage along the inner wall landing of cylinder body to the blow off pipe, washed the inner wall of cylinder body once more from the sewage of cylinder body top landing. The sewage flows out from the sewage discharge pipe, and the cleaning of the inner wall of the cylinder body is finished.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
