Background technology
The blast furnace raw material transportation mode of modern steel enterprise adopts belt transmission, the material being generally sent to blast furnace first stores at feed bin, under feed bin, travelling belt is set, material on travelling belt is sent to transfer feed bin, transfer feed bin uses as transitional storehouse or surge bunker in having bad luck in process of material, the material that transfer feed bin undertaking supplied materials suitable for reading belt falls, haul belt is provided with below transfer feed bin end opening, the material that transfer feed bin end opening falls accepted by haul belt, and material is sent to the charging apparatus of blast furnace roof by haul belt.
Owing to often having bulk or foreign material in blast furnace raw material, bulk or foreign material easily block the feed opening of transfer feed bin, cause transfer feed bin and supplied materials belt to become silted up and expect, have to stop belt running, process, have impact on the normal raw material supply of blast furnace.Along with the maximization of iron and steel enterprise's furnace volume, blast furnace daily consumption inventory rolls up, and requires the equipment failure rate reducing material supply transmitting procedure.
For the manual monitoring occurred in blast furnace material transportation process not in time, easily there is the phenomenon of transfer feed bin and supplied materials belt silt material accident impact blast fumance, be necessary to invent a kind of simple and practical transfer feed bin material transferring monitoring alarm device.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of transfer feed bin material and transmits monitoring alarm device, this monitoring alarm device can be reported to the police in time in limited time on the level of filler material of transfer feed bin is super, make supplied materials belt shut down in time and transmit, prevent the material fault spread that becomes silted up.
The technical scheme solved the problems of the technologies described above is:
A kind of transfer feed bin material transmits monitoring alarm device, it comprises rotating shaft, striker plate, shaft seating, limit switch and limiting stopper, rotating shaft is positioned at the material level upper limit place of transfer feed bin, rotating shaft horizontal positioned, the axis of rotating shaft is vertical with the service direction of haul belt, striker plate is oblong steel plate, the plate face of striker plate is welded to connect along the axis of rotating shaft and rotating shaft, rotating shaft two ends are stretched out outside transfer feed bin, there is shaft seating rotational support at rotating shaft two ends, limit switch is fixed in rotating shaft end face outside, limiting stopper is welded on transfer feed bin outer wall, when the plate face of striker plate is positioned at upright position, limit switch is relative with limiting stopper, limit switch signal line is connected with control setup.
Above-mentioned transfer feed bin material transmits monitoring alarm device, described shaft seating is made up of bearing support, bearing seat, bearing, two bearing support are fixed on the both sides external of transfer feed bin, two bearing seats are arranged on two bearing support respectively, install bearing in each bearing seat, rotating shaft two ends are connected with bearing fit.
The beneficial effects of the utility model are;
The utility model is prescribed a time limit on the level of filler material of transfer feed bin is super, striker plate drives axis of rotation under material promotes, limit switch is along with axis of rotation, limit switch and limiting stopper produce and misplace, the alerting signal of limit switch is transferred in control setup, control setup sends alerting signal, stops supplied materials belt to run with timed unit.The utility model structure is simple, easy for installation, be quick on the draw, reliability is high, use cost is low, can when the material of transfer feed bin reaches limit level and alarm, and make supplied materials belt shut down in time and transmit material, prevent the material fault spread that becomes silted up, solve the super upper manual monitoring in limited time of transfer bin-level not in time, cause transfer feed bin and supplied materials belt to become silted up to expect the problem of accident impact blast fumance.
