Intelligent medicine feeder is a complete set of equipment integrating dosing, mixing, liquid transportation and automatic control. It is mainly applied in pharmaceutical delivery of oil and water wells, gathering and transportation stations and oil pipelines in oil fields, as well as in chemical industry, environmental protection, water supply system and other industries. The device is mainly composed of dosing tank, dosing pump, stirring mechanism, liquid level alarm system, pipeline, control cabinet, diaphragm buffer, filter, insulation device, automatic control device (optional), etc., and is integrated on a base. Users simply install it in the dosing room, connect the dosing pipe and the power to start and put into operation. This factory-integrated device can significantly reduce the work of design and on-site construction, and provides reliable assurance for the quality and on-site operation of the whole machine system. By drawing on the advantages of medicine feeders at home and abroad, the device has the characteristics of compact structure, easy operation and easy to use, and simple installation etc. With high corrosion resistance, its components can be selected according to the international standards such as ASME, SSPC, IEC, ASTM, and ANSI etc.


Intelligent medicine feeder prepares medicine based on the required concentration in the mixing tank, puts in the solution tank after being evenly stirred by the mixer, and delivers the prepared solution dosing point or the designated system with the metering pump. According to the requirements of different technological processes of users, the device can also carry out targeted design and configure necessary software to realize automatic remote control and other functions.
