Working principle of concrete mixing station

Concrete mixing plantDivided into four parts: sand and stone feeding, powder (cement, fly ash, expansion agent, etc.) feeding, water andadmixtureFeeding, transmission stirring and storage。agitatorAfter the control system is powered on, the operation interface of man-machine dialogue is entered, and the system is initialized, including the formula number, concrete grade, slump, production square amount, etc.According to the weight of each bin, measuring hopper detection, output empty or full signal, prompting the operator to determine whether to start the mixing control program。Start the sand and stone belt motor to feed into the metering bucket;Open the butterfly valve of fly ash and cement tank, and start the screw machine to transport fly ash and cement to the metering bucket;Open the control valve of the water tank and admixture tank to allow water and admixture to flow into the metering bucket。After the metering meets the set requirements, the metering bucket door is opened, the ingredients are mixed into the mixer that has been started, and the mixer door is opened at the set time, and the concrete enters the mixing car that has been received。

1.Press each cylinder, control valve and motorConcrete mixingThe requirements of the process operation, the control of each cylinder, control valve and motor must be accurate, stable and reliable。

2.The control system has two working modes, automatic and manual, and the relationship between each other is independent and restricted。

3.The system has good anti-interference ability and perfect alarm self-protection function。

4.By communicating with the computer, the system working state and fault alarm can be displayed 。
