Embodiment 1
[0042] A large-volume concrete cooling water control device, including a circulation pipeline and a temperature acquisition device;
[0043] The circulation pipeline, such as figure 1 As shown, it includes a water pump 1, a first flow divider 3 communicated with the water pump 1 through a main water conduit 2, n branch circulation pipelines 5 selectively communicated with the first flow divider 3, and n branches The second diverter 7 and the cooling water tank 8 where the circulation pipeline 5 merges;
[0044] Water inlet solenoid valves 4 are respectively provided at the joints between the n branch circulation pipelines 5 and the first flow divider 3 , and water inlet solenoid valves 4 are respectively provided at the joints between the n branch circulation pipelines 5 and the second flow divider 7 Return water solenoid valve 6;
[0045] The temperature acquisition device is n temperature sensors, which are respectively arranged at the places where n branch circulation pip...
Embodiment 2
[0052] This embodiment introduces its electric control system on the basis of Embodiment 1. The selective opening / closing of n branch circulation pipelines 5 can be realized through the electronic control system.
[0053] Specifically, the electronic control system includes a control module, and n temperature sensors are respectively connected to the input terminals of the control module by communication or electricity. The n water inlet solenoid valves 4 and the water return solenoid valves 6 are communicatively or electrically connected to the output end of the control module. The control module receives the temperature information of each point collected by n temperature sensors, and analyzes and judges in combination with the preset temperature threshold and cooling rate threshold, and sends an on / off signal to n water inlet solenoid valves 4 and return water solenoid valves 6 instruction.
[0054] When the temperature at a certain point exceeds the preset temperature th...
Embodiment 3
[0056] This embodiment introduces its flow control function on the basis of Embodiment 1.
[0057] The water inlet solenoid valve 4 is equipped with a flow control valve. Combining the temperature information and control requirements of each point collected by n temperature sensors, the flow rate of the water inlet solenoid valve 4 corresponding to the branch circulation pipeline 5 at each point is automatically controlled, thereby controlling the cooling rate of each point.
[0058] The control module receives the temperature information of each point collected by n temperature sensors, and sends a flow adjustment instruction to the flow control valve through a PID algorithm in combination with temperature control requirements.
