Concrete mixing station is divided into four parts: gravel feed, powder (cement, fly ash, expansion agent, etc.) feed, water and admixture feed, transmission stirring and storage. After the mixer control system is charged, it enters the operation interface of the man-machine dialogue, and the system initializes the processing, including the formula number, concrete grade, slump, production quantity and so on. According to the weighing of the silo, metering bucket testing, output material empty or full signal, prompt the operator to determine whether to start the stirring control program. Start sand, stone belt motor into the expected metering bucket; Open the butterfly valve of fly ash, cement tank, start the screw machine motor to transport fly ash, cement to the metering bucket; open the control valve of the silo and admixture pool to allow water and admixtures to flow into the metering bucket.
Metering to meet the requirements of the opening of the metering bucket doumen, ingredients into the activated mixer mixing mixing, to set the time to open the mixer door, concrete into the mixer in the feed.
1. The cylinders, control valves and motors operate according to the requirements of the concrete mixing process, and the control of each cylinder, control valve and motor must be accurate, stable and reliable.
2. The control system has two modes of operation, automatic and manual, and the relationship between them is independent and restricted to each other.
3. The system has good anti-jamming ability and perfect alarm self-protection function. 4. Through communication with the computer, you can display the system working status, fault alarm.
