Step 102, determine according to described pressure, speed and export stream status signal.
In this detection method, owing to can detect the stream situation in airtight chute in real time, operating personnel can know chute whether putty in time, and chute just can take corresponding measure once putty operating personnel, prevents the damage that long-time putty causes equipment.
According to the difference of stream state, for stream state for chute putty state is described detection method of the present invention, as shown in Figure 5, Fig. 5 is the schematic flow sheet of the stream detection method of the chute of another embodiment of the present invention, and this detection method comprises:
The pressure of the stream in the chute that step 201, reception roller are subject to, and roller follows the speed of the stream rolling in chute;
Step 202, when pressure is greater than zero and speed equals zero;
Step 203, output chute putty signal.
In this detection method, step 202 can adopt two determining steps to realize, and such as, first judges whether pressure is greater than zero, then judges whether speed equals zero; Also first can judge whether speed equals zero, then judge whether pressure is greater than zero, detection method of the present invention is not restricted this.Such as, as shown in Figure 6, Fig. 6 is the idiographic flow schematic diagram of the stream detection method of the chute of another embodiment of the present invention, and this detection method comprises:
The pressure of the stream in the chute that step 301, reception roller are subject to, and roller follows the speed of the stream rolling in chute;
Step 302, judge whether pressure is greater than zero; If so, then perform step 303, otherwise can step 301 be back to;
Step 303, judge whether speed equals zero; If so, then perform step 304, otherwise can step 301 be back to;
Step 304, output chute putty signal.
Another kind of embodiment is: described stream state comprises the pre-putty state of chute, when meeting R → 0, exports the pre-putty status signal of chute, and wherein, R is the speed that speed detector detects.
