The top for stating the end of feeding chute is equipped with an opening, installs shaft 104 in opening, flap valve 105 is mounted on the shaft 104
On, which 104 can overturn around the shaft in feeding chute, and when not having material to pass through, flap valve 105 is in certainly
By plumbness, to stop that the high-temperature flue gas in converter is sprayed to feeding chute；When have material by when, flap valve 105 is in object
Under the gravitational force urges effect of material, it is flipped up, so that material passes through；
The outside of the opening of 100 end top of blanking chute groove body is equipped with a flap valve pointer 106, which refers to
Needle 106 is rigidly connected with flap valve 105, and when flap valve 105 is overturn, which makes corresponding deflection；
The flap valve pointer 106 is connect with a limit switch 107, and the limit switch 107 is for detecting flap valve 105
Switch situation, limit switch 107 output signal access PLC system 108 input terminal, the output end of PLC system 108 with it is upper
The input terminal of machine 109 connects, and the working condition of flap valve 105 is fed back to host computer 109.
As an implementation, it is fed using Weighing type vibra feeder to bucket 101 is summarized.
As an implementation, the shape of the flap valve 105 be the rectangle with semicircle, the flap valve 105 by
Thickness is made of the steel plate of 6mm；Naturally when vertical, 105 lateral profile of the flap valve and 100 inner wall of blanking chute groove body
It fits like a glove.
As an implementation, the limit switch 107 is close to switch.
As an implementation, it is 20mm that the top of the end of feeding chute, which is equipped with an opening width,.
As preferred embodiment, the opening is equipped with for overhauling gate valve failure on the outside of the feeding chute
Cover board, for covering above-mentioned opening.When judging that gate valve is in failure, open cover board, to gate valve carry out check or with
It changes.
Preferably, when the flap valve pointer 106 deflects, limit switch 107 sends out flap valve open signal, and will be described
Open signal is transmitted to host computer through PLC system, and host computer display green is fault-free；
When the flap valve pointer 106 resets, limit switch 107 sends out flap valve shutdown signal, and the closing is believed
Number it is transmitted to host computer through PLC system, host computer is displayed in red as fault-free.
In a kind of operational process, Weighing type dispenser weighs material, adds it to and summarizes in bucket 101, according to blanking
Amount and blanking velocity calculate required blanking time T1；
Gate valve 103 is opened, material successively enters by gate valve 103, flap valve 105 in converter, when material is by turning over
105 when plate valve, flap valve pointer 106, which deflects to, reaches position, and limit switch 107 sends out open signal, which is transmitted to
PLC system 108, the open signal is transmitted to host computer 109 by PLC system 108, under host computer 109 shows that green is normal
Otherwise material judges to reach a signal fault or flap valve failure；
Flap valve 105 restores upright position, and flap valve pointer 106 is reset to pass in place, and limit switch 107 sends out closing letter
Number, which is transmitted to PLC system 108, and PLC system 108 calculates reality according to the time that signal is sent out is unlatched and closed
Blanking time T2, by the signal transmission to host computer 109, when T2 is equal to T1, host computer is displayed in red PLC system 108, is judged
Flap valve and gate valve are non-faulting state；Otherwise it is to close limit switch fault or flap valve failure in place；
When T2 is equal to T1, host computer 109 is not displayed in red, judges to close signal fault or gate valve failure in place.
Wherein, the PLC system 108 is debugged using off-line programing, standalone module, is individually called, and simulated operation does not influence
The use of original system.
As a kind of possible embodiment, in the state of no blanking, the flap valve 105 is freely vertical, turnover panel
Valve pointer 106 straight up, close by limit, and host computer 109 is displayed in red；When blanking, flap valve 105 is opened, flap valve pointer 106
Rotation, limit are opened, and host computer 109 shows green.Above-mentioned display is unfaulty conditions.
As a kind of possible embodiment, start blanking, but host computer 109 does not show green, that is, judge it is faulty,
Generating system can send out alarm.
As a kind of possible embodiment, when T2 is equal to T1, host computer 109 is not displayed in red, is also judged as having event
Barrier needs to check limit switch and flap valve.
The feeding chute of the utility model is additionally arranged flap valve, and when not having blanking, flap valve is freely vertical, in smelting furnace
The thermal-flame and high-temperature flue gas of generation are not easy to scurry into feeding chute by flap valve blocking, avoid high temperature to plate valve body
Caused by damage；A small amount of material of discharge outlet avoids the thermal-flame scurried out and high-temperature flue gas calcination, discharge port are not easy
It blocks；Limit switch in the prior art is mounted on inside feeding chute, and is connect with gate valve, in blanking process, works as limit
Switch is unable to judge accurately the practical putting material situation of gate valve when breaking down, lead to the situation of more blankings or few blanking；Blanking
The external side of chute is equipped with opening and cover board for overhauling gate valve failure, keeps the replacement of gate valve more convenient.
The same or similar parts between the embodiments can be referred to each other in this specification.Above-described practicality is new
Type embodiment does not constitute the restriction to scope of protection of the utility model.
