Furthermore, the water feeder comprises a water supply pipe, a water valve, a flow controller, a filter and a water outlet pipe which are connected in sequence.

Further, a material level meter is arranged at the top of the storage tank.

Compared with the prior art, the beneficial effect who has is: adopts a continuous automatic blending mode, which comprises the following steps:

1. the equipment can realize the preparation at any time, and large-scale medicine storage places and equipment are not needed any more;

2. the whole blending process does not need manual participation and is realized by PLC full-process automatic control, thereby greatly lightening the manual load, reducing the manual preparation and greatly reducing the chance of directly contacting the medicament by operators;

3. the blending precision is accurate and stable, so that the subsequent treatment process is stable, and the service lives of other treatment devices are prolonged. On the other hand, the waste of the medicament is avoided, the use efficiency of the medicament is improved, and the treatment cost is reduced;

4. the power consumption of the equipment is reduced by more than 30% compared with that of the traditional equipment, and in an intelligent control mode, the motor is started to operate only when necessary, and the traditional equipment basically maintains the motor to operate continuously for a long time, so that the investment and the operation cost of the series of equipment are effectively reduced, and the equipment is more environment-friendly.
