Abstract
The utility model discloses a distribution trajectory detector for a bell-less top of a blast furnace. The detector comprises a base flange, a holder and a detecting rod. The base flange matching with a mounting flange of a water spray gun at the top of the blast furnace is fixed with the mounting flange of the water spray gun. One end of the holder is fixed onto the base flange, and the other end of the holder is connected with the upper end of the detecting rod through hinges. The detecting rod rotates to be vertical by the aid of self-weight. When charging materials distributed by a chute drop and hit the detecting rod, evident marks are formed, so that distribution trajectory can be detected after the blast furnace is put into production.
Description
Technical field
The utility model relates to the roof material distributing detection technique, more particularly, relates to a kind of blast furnace bell-less roof material distributing track detection device.
Background technology
Blast furnace furnace roof charging system is the critical system during blast furnace is produced, and early stage blast furnace furnace roof charging system adopts the clock-type furnace roof, after the last century the eighties; No bell furnace roof has substituted the clock-type furnace roof gradually; Can not realize annular cloth with comparalive ease because there is the bell furnace roof, fan-shaped cloth, fixed point cloth etc.; State of arts in the stove is regulated more convenient, therefore day by day become the main flow pattern of top charging.
Controlled for the blast furnace operating situation is stablized, the roof material distributing chute is in different angles, different blanking speed; Under the different furnace charge kind situation; The track of cloth changes in blast furnace, must confirm in advance, so that in the adjustment working of a furnace, adopt different gear combination of angles.
As shown in Figure 1; At present; Usually in the charging stage before large blast furnace is constructed and put into operation, all can carry out the test of materials flow gesture determination, method is at furnace roof 0 degree and 180 degree directions a laser transmitter 1 to be set respectively; Form laser network at an angle, noctovisor is set in 90 degree direction person of low position holes.When blast furnace was packed each batch of material into, the track that the track record materials flow is fallen went out the blanking track through the computer simulation program detailed calculated again.The advantage of this method is that calculating and mimic data are more accurate; But shortcoming is that the precision of Equipment Requirements such as installation laser transmitter, pick up camera is high, the time is long; In addition; Therefore the bad adaptability of the furnace roof high temperature dirty environment of these high precision apparatus after blast furnace is gone into operation after blast furnace is gone into operation, is measured roof material distributing chute blanking track and is inappropriate for employing this method.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of blast furnace bell-less roof material distributing track detection device, can after blast furnace is gone into operation, measure roof material distributing chute blanking track.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This blast furnace bell-less roof material distributing track detection device; Be installed on the watering rifle mounting flange of blast furnace furnace roof; Comprise base flange, bracket and feeler lever; Base flange is suitable and fix with watering rifle mounting flange with watering rifle mounting flange, and bracket one end is fixedly arranged on the base flange, and the other end links to each other with the feeler lever upper end through hinge.
Described feeler lever surface is provided with a white scale.
Also be provided with stay cord on the described feeler lever.
In technique scheme; The blast furnace bell-less roof material distributing track detection device of the utility model comprises base flange, bracket and feeler lever; The watering rifle mounting flange of base flange and furnace roof is suitable and fix with watering rifle mounting flange; Bracket one end is fixedly arranged on the base flange, and the other end links to each other with the feeler lever upper end through hinge.This feeler lever in stove through deadweight rotation as for plumbness, the furnace charge that plants when the furnace roof chute drops on and when hitting feeler lever, can form apparent in view vestige, thereby is convenient to measure its cloth track in the blast furnace back of going into operation.
Description of drawings
Fig. 1 is the roof material distributing track detection schematic diagram before existing the operation;
Fig. 2 is the user mode synoptic diagram of the proofing unit of the utility model;
Fig. 3 is the structural representation of the proofing unit of the utility model;
Fig. 4 is that the proofing unit of the utility model is installed the vertical view of back rotation.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 2～shown in Figure 4; The blast furnace bell-less roof material distributing track detection device 10 of the utility model is installed on the watering rifle mounting flange 3 of blast furnace furnace roof 2; Comprise base flange 11, bracket 12 and feeler lever 13; Base flange 11 and watering rifle mounting flange 3 are suitable and fix with watering rifle mounting flange 3, and bracket 12 1 ends are fixedly arranged on the base flange 11, and the other end links to each other with feeler lever 13 upper ends through hinge 14.Described feeler lever 13 surfaces form white scale through white look paint.In addition, also be provided with stay cord 15 on the described feeler lever 13.
The method of use of this proofing unit 10 is following:
When the blast furnace periodical repair; Can furnace roof 2 watering rifles be removed; Concrete quantity and direction of removing can generally preferably be measured eight directions of blast furnace circumference as required, therefore removes eight watering rifles; On these positions, proofing unit 10 is installed in respectively on the watering rifle mounting flange 3 then through base flange 11.After the installation, through hinge 14 feeler lever 13 rotations are swung down, and feeler lever 13 is strained outside stove, make it to fit tightly, be in plumbness with bracket 12 with stay cord 15.At this moment; Production operation swivel chute 5; Furnace charge in the weighing batch can is fallen, write down the gear of materials flow variable valve and the turning angle of swivel chute 5, and the furnace charge that plants when the swivel chute 5 of furnace roof 2 drops on the feeler lever 13 and when hitting feeler lever 13; Can form apparent in view vestige, be convenient to trajectory measurement.After furnace charge cloth is intact, takes out proofing unit 10, and measure feeler lever 13 and hit the distance of vestige from hinge 14 positions to furnace charge and carry out record.At last data measured is simulated with the computer drawing instrument, just can be drawn the track that falls at blast furnace circumference different directions furnace charge.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
