Abstract
The invention discloses a detection device for slag flushing water of a blast furnace. The blast furnace is provided with an iron outlet (1), and the iron outlet (1) is connected with an iron tap channel (2). The iron tap channel (2) is connected with a slag flushing pipeline (8) through a slag channel (3). A slag flushing water pipe (4) is arranged at the position of the slag flushing pipeline (8). The slag flushing water pipe (4) is connected with a pressure gauge (5), and the pressure gauge (5) is connected with a pressure control system through a signal circuit. By means of the technical scheme, the pressure value is fed back to a frame of a display device in real time through a PLC module, and an operator can know the numerical value of pressure first time and carry out corresponding control. The detection device has the beneficial effects that practicability is high, and the numerical value is visual after transformation; the transformation cost is low, and only dozens of meters of a cable is needed for transformation; the labor intensity of the operator is reduced, and workers do not need to come back and forth frequently to carry out watch after transformation; and maintenance is convenient, and cost is low.
