In case filter stick is stuck between emission drum 4 and the back locating wheel 39, emission drum 4 is stuck at once, has a sensor to send to the PLC controller immediately on the transmission system and launches the fault-signal that drum 4 or material toggling roller 3 are stuck.
After receiving fault-signal, the PLC controller closes the power supply of power machine, and motor shuts down, and after several seconds kinds, the PLC controller disconnects for the by-pass valve control of emission with the compressed air inlet, stops compressed-air actuated supply.Then, the PLC controller is connected another by-pass valve control that big cylinder diameter clamps cylinder 8,30, big cylinder diameter clamps the piston rod withdrawal of cylinder 8,30, and after withdrawal put in place, another terminal detecting element that big cylinder diameter clamps cylinder 8,30 sent the signal that puts in place to the PLC controller.
The PLC controller is connected another by-pass valve control of lateral cylinder 36, the piston rod of lateral cylinder 36 stretches out, hook 35 is along with the piston rod of lateral cylinder 36 stretches out simultaneously, and hook 35 leaves the inwall of geosynclinal block 34, makes sealing block base plate 40, sealing block 33 be in free state.After putting in place, another terminal detecting element of lateral cylinder 36 sends the signal that puts in place to the PLC controller.
The PLC controller is connected another by-pass valve control of little cylinder diameter lift cylinder 7, the piston rod withdrawal of little cylinder diameter lift cylinder 7, and after withdrawal put in place, the operator began to clear up the filter stick that is stuck between emission drum 4 and the back locating wheel 39.After fixing a breakdown, device restarts work.
Advantage of the present invention is:
1, the processing characteristics of back locating wheel 39, annulus 38 is improved greatly, because back locating wheel 39 does not have thin-walled, carries out quenching heat treatment, and part should not deform.Annulus 38 processing are relatively simple.
2, cancellation wedge 28 when filter stick direction when motion shown in Fig. 6 upward arrow, only moves axially, and does not do lifting.Because the end face of filter stick does not have to rub with the rising ramp of wedge 28, so the speed that moves axially of filter stick is accelerated to some extent than the mode of traditional filtering mouth bar pneumatic conveying device, the corresponding emission rate that improves novel filter tip bar pneumatic conveying device.
3, behind the cancellation wedge 28, the concaved circular cambered surface of the inner arc surface of annulus 38 and sealing block 33 is on the same horizontal plane, and it is smaller that the inner arc surface of the end of filter stick 2 and annulus 38 produces the possibility that rubs.Filter stick end wrinkle is fewer, has improved the quality after filter stick is launched.
