Abstract

The invention discloses a fully-automatic polymeric agent dissolving and agent dosing integration machine and a use method thereof. The integration machine comprises a water feeding and agent dissolving system, a dry powder adding system, a prepared agent conveying system, a prepared medicine external adding system, an automatic control system, a device integrity steelmaking pedestal and a fixed channel steel, and the water feeding and agent dissolving system comprises a water feeding tube, a solenoid valve, an agent dispensing tank stirrer, an agent dispensing tank liquid meter, an agent dispensing tank overflow tube and an agent dispensing tank evacuating tube; the prepared agent conveying system comprises a conveying pump, an agent dispensing tank agent outlet and a conveying pump outlet; and the prepared medicine external adding system comprises a cylinder agent storage tank, an agent dosing pump, an agent storage tank liquid meter, an agent storage tank stirrer, an agent storage tank overflow tube, an agent storage tank evacuation tube, an agent storage tank agent outlet and a dosing pump output opening. The use method of the integration machine comprises parameter setting, agent dispensing process control, conveying pump running control and agent adding and conveying automatic cycle. The integration machine has the advantages of reduction of the running cost and realization of automatic control of agent dissolving and agent dosing.

Description

technical field [0001] The invention relates to environmental protection equipment in the fields of water supply and drainage and industrial papermaking and a use method thereof. In particular, it relates to a fully automatic polymer drug dissolving and adding machine and a use method thereof. Background technique [0002] The function of polymer automatic dissolving and dosing equipment is to dissolve and prepare powdery polymer pharmaceuticals into liquid pharmaceuticals of different concentrations required by various industries. Dissolution and dosing of flocculant PAM; dissolving and dosing of industrial papermaking PVA / CMC, bleaching agent, adhesive, paper strength enhancer, etc., and whether the equipment can achieve sufficient and rapid dissolution of polymer dry powder medicine, liquid medicine concentration and The automatic and precise preparation of the variable dosage is to ensure the stable water quality of sewage treatment, industrial papermaking and other ind...

AI Technical Summary

Problems solved by technology

That is to automatically open the water inlet electromagnetic valve to enter water, and start the agitator and dry powder dosing screw propeller at the same time. Dosing is done at any time and within the same period of time. However, it is difficult to achieve the above goals in actual operation. First, the water supply pressure determines the water intake per unit time, and the water supply pressure cannot always be constant and stable, so the water intake in the same period It is unequal. Secondly, because the three tanks are connected in series, when the liquid level of the storage tank drops to a low level, the prepared drug solution in the remaining part of the drug dissolution tank will also affect the control of the concentration of the drug solution. Therefore, the three tanks are connected in series. It is difficult to prepare a precise concentration of liquid medicine for the trough-type polymer automatic dissolving and dosing equipment

[0005] 2. It is difficult to adapt to the preparation of precise concentration for drugs with different dissolution time requirements (or different ambient temperatures for the same drug)

Different agents have different dissolution times, and even the same agent requires different dissolution times under different environmental conditions. It is unrealistic to rely solely on the residence time of agents in the dissolution tank and aging tank to meet the needs of different dissolution times.

[0006] 3. It is not easy to realize the preparation of pharmaceuticals with variable dosage requirements

For example, the user only needs to prepare a certain concentration of 1 / 2 or 1 / 3 of the volume of the dispensing equipment. Currently, the automatic dissolving and dosing equipment on the market does not have this automatic preparation function.

[0007] 4. The overall structure design is not compact, takes up space, and is inconvenient to install

[0008] 5. The drug outlet and emptying pipe are designed at the lower part of the side wall of the equipment, which cannot completely empty the liquid medicine in the equipment, which is not conducive to equipment cleaning and maintenance

[0009] 6. The intelligent control level of the automatic control system is not high
