Compared with the prior art, the liquid mixing device has the remarkable advantages of being reasonable in structure, high in efficiency, low in cost, high in reliability and corrosion resistance, and the like.

Description

Technical field: [0001] The invention relates to the technical field of gas-liquid mixing equipment, in particular to a liquid mixing device with reasonable structure, high efficiency and low cost, which can be widely used in food, pharmaceutical, chemical and other fields and its control algorithm. Background technique: [0002] As we all know, many supplies in people's production and life, such as disinfectant or carbonated drinks, are made by mixing multiple solutions, or even obtained by mixing multiple gases with multiple solutions. This type of product needs to use liquid mixing equipment during the deployment process. Currently, this type of equipment generally has a storage chamber and multiple infusion or gas delivery mechanisms connected to the storage chamber. In order to improve the mixing efficiency and control the gas and liquid Mixing ratio, infusion or gas delivery mechanisms are generally equipped with liquid inlet pumps or air pumps, which need to provide e...
