Background technology
Pressure ball machinery is mainly used in the compressing of various granular material, and be characterized in that briquetting pressure is large, main frame revolution is adjustable, is furnished with spiral feeder.China's metallurgy industry lime powder went out of use mostly in the past, or changed and do other purposes, and cause the significant wastage of resource, along with the growing tension of energy resource, the utilization of metallurgy industry lime powder is more and more subject to people's attention.Through scientific research, solve this problem from the relevant institutes of metallurgy industry over 2002, namely adopt high pressure powder ball press, by kiln discharge powder pressing balling-up block, for smelting, at present, external part steel mill and the Baosteel of China, Anshan iron and steel plant etc. use.Pressure ball machinery is mainly used in---the ball agglomeration processed of coloured and ferrous metal breeze, and directly enter stove and smelt, improve added value.Every metallurgy industry waste material, auxiliary material need go up stove, all needs ball press.Such as: magnesium metal furnace charge pelletizing, dedusting ash, pond mud, oxide skin, slag, Iron concentrate, aluminium ashes, silicomanganese breeze etc.Pressure ball mechanical roller skin adopts 65 manganese castings.After special thermal treatment, hardness can reach more than 58 degree.Roller skin adopts combination assembling, replaceable after wearing and tearing.Dry powder ball press has buffer unit, can exempt from hard object impact by proterctive equipment better.Pressure ball machinery is by mair motor: be with through v shape, reach decelerator, decelerator communications and liaison axial organ, reach driving shaft again by a pair exposed gear, ensure two roll shafts synchronous (piston of the reverse > of constant speed wherein driven roll hydraulic jack withstands being withstood by wedge of < constant pressure type), system pressure is ensured by hydraulic circuit and hydraulic control valve and accumulator, material enters forming machine hopper by storage bin equably through dosing device, regulated by the adjustment flashboard on hopper, material is entered in the middle of pair roller uniformly, the unit briquetting pressure that the pair roller of constant speed antiport carries out compressed material is changed from small to big, at pair roller line of centres place, briquetting pressure reaches maximum, after this line crossed by material, briquetting pressure diminishes rapidly and makes material enter de-spherical state to take off ball smoothly.If but material can not be entered in the middle of pair roller through dosing device equably by storage bin; then can produce because the uneven formation of material is deposited in the situation in the middle of pair roller; now required between pair roller hydraulic fluid pressure will increase sharply; cause that the move toward one another of pair roller stops, equipment fault shuts down and run, " machine of choking " that be namely commonly called as.
Summary of the invention
The object of the invention is to overcome above drawback, provide a kind of machine fault of choking that can process above reason in time and cause, structure is simple, and automation journey is high, uses and easy for installation, and a kind of ball press that cost is low is prevented choking the control device of machine.For achieving the above object, the technical solution used in the present invention is: the present invention relates to a kind of ball press and to prevent choking the control device of machine, particularly relate to the control device of a kind of roll by the anti-machine of choking of the ball press of hydraulic control, device comprises Hydraulic Station 1, Hydraulic Station in-line 2, hydraulic manifold block 3, Hydraulic Station return line 4, hydraulic manifold block flow tee pipe 5, pressure transmitter 6, pair roller in-line 7, hydraulic manifold block controls cable 8, pressure transmitter controls cable 9, PLC control program 10, PLC programmable logic controller (PLC) 11, industrial control computer 12, electrical control cabinet 13 forms, it is characterized in that a kind of ball press prevent choking control device of machine adopts PLC control program 10 pairs of hydraulic manifold blocks 3, pressure transmitter 6 carries out action control and data transmission to carry out the automatic adjustment of the hydraulic fluid pressure of roll shop building.The top board of Hydraulic Station 1 is installed with hydraulic manifold block 3.The oil-in of hydraulic manifold block 3 is connected with Hydraulic Station in-line 2, and oil return opening is connected with Hydraulic Station return line 4, and oil-out is communicated with pair roller in-line 6 by hydraulic manifold block flow tee pipe 4, can by Stress control at required numerical value; When system stalls, oil circuit control pressure also declines, and can make the rapid stop motion of parts, plays self-locking action.Hydraulic manifold block flow tee pipe 5 one end is connected with pair roller in-line 7, and the other end is connected with pressure transmitter 6.PLC programmable logic controller (PLC) 11 is installed in electrical control cabinet 13.
advantage of the present invention is mainly reflected in:
1, structure is simple, and automation journey is high, uses and easy for installation;
2, machine fault of choking can be processed in time, the production loss avoiding equipment downtime to cause and manual maintenance's amount.
accompanying drawing illustrates that 1 is that a kind of ball press is prevented choking the control device structure chart of machine:
