[0003] The working principle of the traditional dosing equipment is that the device realizes full-automatic operation through a PLC control system. When it is detected that the liquid level in the storage tank is lower than the middle liquid level, the system automatically starts the water supply system electromagnetic valve, and after a delay, the dry powder dosing machine starts dosing, and the stirrer works. When the liquid level reaches the high liquid level, the system automatically stops liquid preparation until the liquid level is lower than the middle liquid level again.

[0004] The safety protection of the traditional dosing equipment is that the device has complete automatic protection measures, such as a filter is arranged in the pipeline of the dosing device to prevent large-particle solid substances from entering the metering pump and avoid damaging the metering pump. When the residual amount of the medicament in the medicament barrel approaches the limit value, the low liquid level alarm device gives an alarm signal to inform the on-duty engineer to supplement the medicament in the medicament barrel to prevent the dosing pump from being empty and to protect the control motor of the dosing pump, thereby ensuring the stable and safe operation of the system.

[0005] The technical parameters of the traditional dosing equipment are that the metering accuracy of the metering pump can be up to ±1%, the flow range is from 1L / h to 18000L / h, the pressure range is from 0.1MPa to 25MPa, which can meet the needs of different scenes. The medicament barrel of the traditional dosing equipment is generally circular and is made of PE material, which has a translucent material and is convenient for observing the residual amount of the medicament in the barrel from the outside, and the service life is generally more than 10 years.

[0006] In the process of implementing the technical method of the utility model embodiment, the present applicant has found at least the following technical problems in the prior art:

[0007] 1) For high-concentration and high-viscosity raw materials, it is generally necessary to dilute and stir to prepare a certain concentration of liquid medicine, and the dosing accuracy is not accurate enough, and the dosing control is relatively rough.

[0008] 2) The equipment is relatively large in size, and generally needs to be equipped with a medicament barrel, a medicament storage tank (or pool) and a stirring device.

[0009] 3) Only in the set logic control program operation, unable to achieve intelligent dosing, when the external conditions change, need manual intervention to ensure safe operation.
