Description of drawings
Fig. 1 is a front view structural representation of the present invention.
The specific embodiment
See Fig. 1; It comprises be mixed into water unit, give material unit, preparing tank 8, drug delivery pump 12; The import that is mixed into water unit is communicated with high-temperature steam condensate A and low temperature demineralized water B respectively; The import of preparing tank 8 is led in the outlet that is mixed into water unit, leads to the import of preparing tank 8 for the outlet of material unit, and the outlet of preparing tank 8 connects drug delivery pump 12.
Be mixed into water unit and specifically comprise flow control valve 4, blender 5, temperature control instrument 6, water inlet switch valve 7; The import that flow control valve 4 backs connect blender 5 is installed on the pipeline of low temperature demineralized water B; The pipeline of high-temperature steam condensate A directly connects the import of blender 5, and the port of export of blender 5 is equipped with the import of temperature control instrument 6, water inlet switch valve 7 back connection preparing tanks 8 successively;
Preparing tank 8 has agitator 9; The bottom of preparing tank 8 is provided with impurity floss hole 10; The outlet of preparing tank 8 is led to holding vessel 13 through drug delivery pump 12; Preparing tank 8, holding vessel 13 all are equipped with attemperator 11.
Its operation principle is following: high-temperature steam condensate A and low temperature demineralized water B get into blender 5 backs respectively and mix outflow; Temperature control instrument 6 is according to the requirement of mixing water temperature; FEEDBACK CONTROL flow control valve 4 is regulated the cold water influx, makes the mixed temperature of hot and cold water satisfy medicament preparation requirement; Mixing water get into preparing tank 8 reach set liquid level after, water inlet switch valve 7 cuts out, agitator 9 is started working, the spiral dispenser 3 of weighing starts simultaneously, discharge valve 2 is opened, material slowly falls into spiral dispenser 3 backs of weighing from warehouse 1 and gets into preparing tanks 8.After quantitative mass transport was intact, power-equipment stopped in succession, and the medicament preparation finishes, and drug delivery pump 12 starts, and drug delivery is arrived holding vessel 13.After the preparing tank drug delivery finished, drug delivery pump 12 quit work, and the inlet valve 7 of preparing tank is opened once more, got into the medicament preparation and carry to store repetitive routine.Thus, go round and begin again and carry out medicament preparation.Preparing tank and holding vessel adopt attemperator 11 to carry out the tank body insulation, prevent the medicament cooling, and urea is separated out.Preparing tank can be regularly from the bottom impurity floss hole 10 impurity that gathers for a long time in the jar is discharged.
