Liquid tank and liquid dispensing system. Among them, the liquid preparation system includes several liquid preparation tanks, pipelines, pumps, and a main mixing tank. The pipelines connect each liquid preparation tank and the main mixing tank, and the liquid is transported from the liquid preparation tank to the main mixing tank through the pump. In addition, the liquid dispensing system also includes a gas delivery pipe, a pressure regulating device, and a control device. The pressure regulating device is connected to the control device in communication, and the gas delivery pipe is connected to the liquid dispensing tank and can introduce gas into the tank. This utility model introduces the residual liquid medicine in the pipeline into the mixing tank through pressure difference, thereby reducing the amount of wasted liquid medicine, improving the utilization rate of liquid medicine, saving the cost of producing drugs, and achieving automated operation to improve production efficiency.

With the development of medical technology and the continuous improvement of pharmaceutical level, the technology of producing drugs by mixing different components of drugs in proportion is becoming increasingly mature.

In the process of drug preparation, drugs from different mixing tanks are usually mixed in a total mixing tank. Among them, different types of drugs are mainly introduced into the mixing tank through pumps and pipelines connecting the mixing tank and the mixing tank.

However, in the existing technology, during the process of using a pump to extract the liquid medicine from the mixing tank, after most of the liquid medicine is pumped from the mixing tank to the main mixing tank, there will still be residual liquid medicine in the pipeline. When the pump is turned off, the medicine will flow back into the mixing tank, which not only causes a large amount of waste of medicine, but also results in the proportion of medicine mixed into the total mixing tank not being consistent with the pre-set proportion.

Our company provides a liquid dispensing system that can automatically regulate the residual liquid in the pipeline into the main mixing tank after the pump is turned off.

The liquid distribution system includes several liquid distribution tanks, pipelines, pumps, and a main mixing tank. The pipelines connect each liquid distribution tank and the main mixing tank, and the liquid is transported from the liquid distribution tank to the main mixing tank through the pump. The liquid distribution system also includes a gas pipeline, a pressure regulating device, and a control device. The pressure regulating device is connected to the control device in communication, and the gas pipeline is connected to the liquid distribution tank and can introduce gas into the liquid distribution tank.

Compared to existing technologies, the liquid dispensing system uses a pump to transfer the liquid from the dispensing tank to the main mixing tank and then turns off the pump. The pressure inside the dispensing tank is adjusted by a pressure regulating device, and the residual liquid in the pipeline is introduced into the main mixing tank through the pressure difference. This ensures accurate ratio of each liquid, reduces liquid waste, improves the utilization rate of liquid, saves the cost of producing drugs, and improves production efficiency through automated adjustment operations achieved by the control device.

The side wall of the mixing tank is also equipped with a temperature regulating device, which is connected to the control device for communication.

The control device sends the temperature judgment result in the form of an electrical signal to the temperature regulating device to adjust the temperature inside the dispensing tank, ensuring that the components in the medicine are fully dissolved.
