The dosing pipeline 3 is connected to the circulating pipeline 2, a plurality of dosing pipelines 3 can be arranged on the circulating pipeline 2 side by side, a dosing valve 31 for controlling on-off is arranged on the dosing pipeline 3, the on-off of the dosing pipeline 3 is controlled through the dosing valve 31, when the dosing valve 31 is opened, the chemicals in the circulating pipeline 2 can be discharged outwards, and the chemicals are discharged through the dosing pipeline 3; the medicine feeding pipeline 3 is butted with a medicine bottle or a medicine bag which needs to be injected with medicine. Completing the process of adding medicine.
The medicament in the medicament adding system is always in a circulating flowing state, the medicament adding pump can operate in a stable state, stable pressure is kept at each position in the circulating pipeline 2, the medicament pressure at each medicament adding pipeline 3 is kept stable, and each medicament adding pipeline 3 can discharge the medicament outwards at basically equal constant speed; the flow of the medicament in the circulating pipeline 2 is larger than the amount of the medicament discharged from the medicament feeding pipeline 3, and the redundant medicament which is not charged is returned to the medicament storage box 1 again for recycling. The system enables the medicine to circularly flow by arranging the circulating pipeline 2, the pressure at each position in the circulating pipeline 2 is always kept uniform, the overlarge pressure difference in the medicine adding pipelines 3 is avoided, and the medicine adding process is more stable; each dosing point is accurately added, manual inspection is not needed, only inspection is needed, and the labor intensity of workers is reduced. The whole adding system is simple and reliable, easy to maintain and high in controllability.
On the basis of the scheme, the medicament adding system is provided with a filter in front of a dosing pump, a filter is arranged in front of a dosing valve 31, and a filter is arranged at the return end of a circulating pipeline 2; the filter before the dosing pump can perform primary filtration before the medicament enters the circulating pipeline 2 from the medicament storage box 1, so that the possible residue in the circulating pipeline 2 is reduced; the filter in front of the dosing valve 31 can be a T-shaped filter, and the filtering is performed before the medicament enters the medicament bottle, so that the filled medicament is prevented from containing impurities; the filter at the return end of the circulating pipeline 2 filters impurities before the medicament returns to the medicament storage box 1; impurities in the medicament are fully filtered through triple filtration, and filter elements or filter screens of all the filters are replaced regularly.
Preferably, a flow meter 32 is arranged on the dosing pipeline 3, the control system controls the dosing valve 31 to be closed according to a detection signal of the flow meter 32, the dosing valve 31 can adopt an electromagnetic valve, the flow meter starts to detect when the dosing valve 31 is opened, and the dosing valve 31 is closed by the control system when the flow meter detects that the amount of the flowing medicament reaches the filling amount, so that one-time filling is completed.
