Embodiment 1

[0019] Such as figure 2 As shown, there are a total of 302 slag bags in the slag slow cooling field, correspondingly there are 302 pneumatic cut-off diaphragm valves, which are divided into 20 groups, and data acquisition devices are installed near each valve group on site. Each data acquisition device can access about 20 valve measuring point signals, and the signal type is DI or DO. Corresponding to the recombination of each valve group, configure the bus module, a total of 17 sets of signal acquisition devices, the signal acquisition devices are set in the communication box, numbered IB-0101-01~17. The positions of each valve, valve group box and communication box are as follows: figure 2 shown. The specific configuration is as follows:

[0020]

[0021] The network configuration and the internal configuration diagram of the valve group are as follows: image 3 shown. Configure dual-network communication interfaces on the acquisition device to form A-network and B...

Abstract

The invention discloses an optimized slow slag cooling field automatic spraying system. Integrated design is performed for a control value on a spray water branch pipe to form a standardized valve group. Through a bus transmission technology, data acquisition devices are installed at respective valve groups on the spot. The data acquisition devices acquires valve monitoring signals firstly, use aProfibus communication protocol and send all valve signals to a control system through a Profibus bus to realize intelligent online monitoring of the slow slag cooling field automatic spraying. The optimized slow slag cooling field automatic spraying system, while realizing an automatic spraying function, saves a large number of installation materials such as cables and gas source pipes, avoids damage to the control valves and the cables caused by the high-temperature environment and slag blasting in a slag pack area, guarantees the operation safety of maintenance workers, is improved in maintainability, improves the selection efficiency of the slow slag cooling field, and finally achieves a purpose of improving production efficiency and reducing energy consumption.

Description

technical field [0001] The invention relates to an automatic spraying system, in particular to an optimized automatic spraying system for slow cooling of slag. Background technique [0002] The slow slag cooling field is widely used in various copper smelting plants. The smelting high-temperature liquid slag is transported to the slow slag cooling field through slag ladles and slag carts, and undergoes regular water cooling and air cooling in turn. The main purpose is to cool all kinds of slag in the slag bag for subsequent crushing and slag recycling. [0003] The spray system of the slag slow cooling field is mainly composed of water supply main pipe, water supply branch pipe, slag bag, manual valve, automatic valve, return pipe tank and so on. At present, there are two control modes in the spraying system of domestic slag slow cooling field, namely manual mode and automatic mode. The difference between the two lies in whether the valve on the water spray pipe correspond...
