Description
Technical field
The present invention relates to molybdenum-iron technical field of smelting, especially relate to a kind of granular material and partly to flow automatically automatic feeding device.
Background technology
The mixture homogeneity of molybdenum-iron smelting material is one of important parameter of technology controlling and process.Current, advanced molybdenum-iron proportioning process extensively adopts built-in spiral decrement output unit, coordinate DCS control system, uniform and stable material delivery rate control objectives is made to be able to smooth realization, ensureing molybdenum-iron smelting material component degree of uniformity simultaneously, also providing reliable guarantee for improving molybdenum-iron smelting economy index.But this technique requires high to the physical specification that material is prepared in advance, preparation cost is caused to rise, especially the helicallobe rate of wear accelerate and easily bring out spiral " get stuck " cause feed proportioning system sudden stop Frequent Troubles, cycle of run is short, maintenance cost is high, Given this urgently built-in spiral output unit is optimized.
Summary of the invention
In order to overcome the deficiency in background technology, the invention discloses granular material and partly to flow automatically automatic feeding device.
In order to realize described goal of the invention, the present invention adopts following technical scheme: a kind of granular material partly flows automatically automatic feeding device, comprises feed bin, electrical control cabinet, Weighing control instrument, frequency converter; Described feed bin upper end arranges feed auger, described feed auger connects electrical control cabinet, measuring balance body is provided with in the middle part of described feed bin, described measuring balance body is provided with weight sensor, and described weight sensor connects Weighing control instrument, and described Weighing control instrument is connected with electrical control cabinet, it is characterized in that: the discharging opening of described feed bin is outside equipped with external Bidirectional discharging spiral, described Bidirectional discharging spiral connects frequency converter, and frequency converter connects Weighing control instrument, is controlled by DCS control system.
Bidirectional discharging spiral described in the utility model arranges speed sensor, and the lower end of described feed bin is provided with PLC back-blowing device, and described speed sensor connects PLC back-blowing device.
Bin outlet described in the utility model has angle of inclination, and angle of inclination is greater than the dynamic angle of setting parameter of material.
Owing to have employed technique scheme, the present invention has following beneficial effect: adopt granular material described in the utility model partly to flow automatically automatic feeding device, it is uniform discharge device during external helical rotation, be material fluid stopping device during stopping, prevent material from overflowing, there is double function, self the potential energy gravity flow that especially can effectively utilize material during helical rotation draws off, and energy consumption is low, weares and teares little; The design of two-way spiral of avoiding the peak hour makes material discharged amount continuous uniform, for helicallobe specification design and ensure that equipment running frequency provides and adjust interval widely, make equipment de-sign and flow target value setting become simple; Stop material to flow to both helical ends simultaneously, prevent material to the wearing and tearing of drive bearing and leak the distortion that material causes ingredients by weight value; External spiral greatly reduces the sectional pressure of material to it, and abrasion factor significantly reduces; PLC control setup, can get rid of " scaffold " phenomenon that moist material produces immediately.Namely, when material material lagging occurs at bin blanking mouth because of " scaffold ", the great-jump-forward signal that driving motor running velocity is accelerated passes to rapidly PLC unlatching pressure gas and dredges, and material immediately falls and flows, and local signal does not disturb DCS control system.
Due to the external discharge outlet at feed bin of Bidirectional discharging spiral, silo discharge port space is abundant, and being has coarsegrain foreign material also can be spun default storage bucket to spiral bottom, and avoid spiral stuck, time spare time can clear up from late gate easily.Adopt granular material described in the utility model partly to flow automatically automatic feeding device, what can realize drawing off described material evenly precisely controls.The maximum processing limit of built-in helicallobe of the prior art is 680 tons, and existing external helicallobe surpasses more than 20000 tons; Operation rate rises to more than 99% by 80%; Flow uniformity meets technological requirement completely, the up-to-standard rate 100% of molybdenum-iron; Meanwhile, also greatly saved cost, separate unit spiral year saves maintenance cost 20,000 yuan.
