Description
Technical field
The present invention relates to a kind of stock rod debugging apparatus and debugging positioning method of definite blast furnace charge level reference point, belong to the blast furnace probing rod field of measuring technique.
Background technology
Blast furnace probing rod is the charge level test set that detects the materials such as ore and coke in the State of Blast Furnace, and the situation that confession smelting operation personnel transfer with material in the visual observation stove is controlled the quantity discharged of the materials such as ore and coke in the stove simultaneously.When the material in stock rod detects stove dropped to the charge level of setting, the stock rod automatic lifting was to stop bit, and the materials such as ore and coke discharge in State of Blast Furnace according to the technical process set(ting)value.Discharge of materials is complete, and stock rod automatic stop stop bit begins automatically to transfer by the speed of setting, transfer to the charge level of material in the stove after, stock rod is supported by material, follows subsequently material and descends, until when again detecting material in the stove and dropping to the charge level of setting, the stock rod automatic lifting, work so moves in circles.In the metallurgy industry ironmaking production, stock rod plays very important effect as the eyes of blast furnace, and it both provided accurately stockline foundation for the blast furnace operating person, also be the instruction person of sending that the roof material distributing system works begins simultaneously, the accuracy of blast furnace probing rod measurement charge level is just particularly important.In the background technology, two stock rod test sets are installed in the blast furnace, the charge level that detects when two stock rods differs larger, can't judge that charge level has problem, or the stock rod test set has problem, can only blast furnace staying, allow the stager estimate to judge (first: whether the range estimation charge level poor too many, second: estimate two stock rods be put into zero stockline position whether can the alignment fiducials point); If wherein a chi head comes off, can only debug with reference to the stockline degree of depth of another stock rod, and another stock rod is in normal operation, stockline shows moving down in continuous variation with charge level, operate very inconvenient, but also will finish in the cloth gap, be subjected to cloth time limitation (cloth must be carried chi), need utilize repeatedly the cloth interval to debug and finish.With the debugging of this means of artificial visually examine, be subjected to many-sided restriction such as place, light, personnel, accuracy is low, and large, the debugging of stockline error at zero point is loaded down with trivial details to affect production.
Summary of the invention
The object of the invention provides a kind of stock rod debugging apparatus and debugging positioning method of definite blast furnace charge level reference point, need not manually estimate again when judgement and debugging, the detection stockline is accurate, when changing stock rod and hanging one's head without damping down, debug convenient and simple, be not subjected to the blanking time limitation, reduce labour intensity, solve the problems referred to above that background technology exists.
Technical solution of the present invention is:
A kind of stock rod debugging apparatus of definite blast furnace charge level reference point, comprise that stock rod is hung one's head, absolute value encoder, motor, cylinder, hawser, ball valve and blast furnace pipeline, the blast furnace pipeline is provided with ball valve, the output of motor is connected with cylinder, hawser one end is wrapped on the cylinder, the hawser the other end passes the blast furnace pipeline and ball valve enters in the blast furnace, and hanging one's head with stock rod is connected; Described motor, drum shaft are provided with absolute value encoder.
Described motor, drum shaft are provided with stopper; Described blast furnace pipeline is provided with the stock rod access opening.
Described absolute value encoder is rotation multiple circles absolute value encoder.
Field condition is, has pressure that coal gas is arranged in the stove, and all enter equipment in the stove and all add sealing and prevent pressure, gas leakage.For making in the stove and atmospheric isolation, the debugging apparatus of stock rod is connected with pipeline with stove is interior, is convenient to sealing, and ball valve is installed on the pipeline, and ball valve is closed buffer action, and ball valve is opened stock rod and can be led in the stove.
A kind of debugging positioning method of definite blast furnace charge level reference point adopts above-mentioned stock rod debugging apparatus to carry out, and comprises following processing step:
1. determine on the ball of ball valve along on the clinker tile in blast furnace along distance H; This numerical value is changeless;
2. transfer the chi reference point along being defined as blast furnace probing rod on the ball of ball valve, then debug by absolute value encoder;
3. stock rod is hung one's head and mention above the ball valve, close ball valve, with the stock rod edge on the ball that is placed on ball valve of hanging one's head, then absolute value encoder is put number, and numerical value is H;
4. open ball valve, prize gently the stock rod electromotor brake, stock rod is hung one's head slowly toward transferring, absolute value encoder shows that numerical value is from H correspondence subtrahend down, when stock rod is hung one's head lower when aiming in the stove on the clinker tile along (zero stockline), absolute value encoder demonstration numerical value also reduces to zero from H, transfers the chi reference point along being defined as blast furnace probing rod on the ball of ball valve, finishes the stock rod debugging.
On the ball of described ball valve along on the clinker tile in the blast furnace along distance H, calculate by consulting blast-furnace body and stock rod machinery mechanical drawing.
Under the normal production status, if suspect that a certain stock rod test material level is inaccurate, need to reorientate, stock rod be hung one's head mention the ball valve top, close upper ball valve, open the access opening of ball valve top, with the stock rod edge on the ball that is placed on ball valve of hanging one's head, then absolute value encoder is put number, numerical value is H, close access opening, get final product.
Under the normal production status, if changing stock rod hangs one's head, stock rod hung one's head mention the ball valve top, close upper ball valve, open the access opening of ball valve top, the replacing stock rod is hung one's head, with the edge on the ball that is placed on ball valve of hanging one's head of the stock rod after changing, then absolute value encoder is put number, numerical value is H, close access opening, get final product.
Positively effect of the present invention is: check and correction stock rod reference point when not needing blast furnace staying, can debug stock rod during normal production, judge and during debugging without the artificial visually examine, the detection stockline is accurate, run in process of production stockline and judge and unclearly can revise the charge level reference point, without damping down, debug convenient and simple when changing stock rod and hanging one's head, be not subjected to the blanking time limitation, reduce labour intensity.
