Further, the pipeline transportation tail station device further comprises a first pipeline 2 and a second pipeline 5, wherein the first pipeline 2 is used for connecting the main pipeline 1 with the stirring tank 4, the second pipeline 5 is used for connecting the main pipeline 1 with the ore separating box 11, the first pipeline 2 is provided with a first control valve 3 used for controlling the on-off of the first pipeline, the second pipeline 5 is provided with a second control valve 6 used for controlling the on-off of the second pipeline, and at least one of the first control valve 3 and the second control valve 6 is in an open state.

In addition, the stirring tank 4 is connected with the ore separation box 11 through a third pipeline 7, the third pipeline 7 is provided with a lifting pump 8, and the lifting pump 8 is used for providing power to convey materials in the stirring tank 4 to the ore separation box 11.

It can be seen that iron ore concentrate with the concentration of 63-67% is sent to the tail station device through the main pipeline 1 by the pipeline initial station device, when the iron ore concentrate is in a normal conveying state, the first control valve 3 is closed, the second control valve 6 is opened, ore pulp conveyed by the main pipeline 1 can directly enter the ore separating box 11, and the ore pulp is filtered and then sent to the next procedure; in an emergency state, the second control valve 6 is closed, and the first control valve 3 is opened, so that the ore pulp can enter the stirring tank and is sent into the ore separation box 11 through the third pipeline 7 by the lifting pump 8. Obviously, in order to prevent the burst of the pipe due to the sharp rise of the pipe pressure when the first control valve 3 and the second control valve 6 are closed at the same time, both the first control valve 3 and the second control valve 6 are set such that at least one thereof is in an open state.

In this way, in the normal conveying state, the underflow of the thickener 13 can return the concentrated pulp to the ore separation tank 11 through the fourth control valve 21 and the second underflow pump 20.

That is, the underflow of the thickener 13 can enter the agitator tank 4 in one way, and can enter the ore separation box 11 in the other way. In addition, the thickener 13 is also connected with a circulating water system 15, and moisture generated after the ore pulp is thickened by the thickener 13 can enter the circulating water system 15.

When the belt conveying system is out of order, that is, the operation signal of the belt conveying system is 0, the PLC controls the first control valve 3 to automatically open the valve. When the upper computer screen sends a valve closing signal, the in-place closing signal is 1, the screen opening signal is 1 and the valve stopping signal is 1, the first control valve 3 is in the valve closing state and can be self-locked, and the valve closing function is realized after the preset time (set to 26 seconds) and then the valve closing is stopped; in addition, after the upper computer screen sends a valve stopping signal for 5 seconds, the valve stopping signal is stopped.

In addition, the control program diagram of the valve failure is shown in fig. 6, and specifically, when one of the open valve is open to the position and the close valve is closed to the position fails, a valve failure command is reported.
