Description
Technical field
The present invention relates to pallet simulation test, particularly to the assembly simulation assay device of a kind of pallet fire grate bar.Pallet fire grate bar assembly simulation assay device designed by application, can simulate the assembling on sintering pallet under fire grate bar normal temperature condition, running status.The present invention can be used in the trial-production test of fire grate bar product, it is not necessary to tests on large scale sintering machine trolley, reduces experimentation cost and empirical risk.
Background technology
Fire grate bar is one of crucial consumable accessory of sintering pallet.Having the fire grate bar being much arranged in order on sintering pallet, the boss between adjacent fire grate bar is connected, and forms gap between fire grate bar, and the fire grate bar of permutation and combination is used for carrying raw materials for sintering, convulsion, sintering.During sintering, the temperature of short time (about 15 min) interior sintering deposit is up to about 1100 DEG C, the surface temperature of fire grate bar is up to 800-950 DEG C, along with the operation of chassis is cooled to again about 100-300 DEG C, in high-temperature sintering process, fire grate bar should bear sintering mineral aggregate action of gravity, bear the high speed impact abrasion of powder, gas two phase flow again, when chassis walking and batch turning, fire grate bar still suffers from strenuous vibration, and operating mode is the most severe.
The large-type sinterer of traditional produced on-site is belt or circular travelling sintering machine.As shown in accompanying drawing 1,2, the structure of pallet includes chassis piece frame 1, running roller 2, baffle plate 3, fire grate bar 4 etc., and furnace grid 4 is the main consumable accessory on sintering pallet, typically with heat-resisting, antifriction alloy casting.The furnace grid that number row is the most adjacent is typically arranged in the bottom of each sintering pallet, often arranges according to even more than 100 fire grate bar of sintering pallet width design tens, has gap for sintering feed negative pressure down draft sintering between each fire grate bar side.Multiple pallet sequential arrangement, the rail set of sintering machine runs, its work process is: is done continuous print by the head star wheel 5 of actuator drives and rotates, chassis is lifted to upper horizontal rail by lower tracks through head bend, star wheel toothed plate continues to press on chassis card wheel, owing to star-wheel ceaselessly rotates, continuous print promotes the next one to be taken turns by the chassis card lifting to horizontal rail, whole car team of appearing on the stage thus is made to move to sintering machine tail, when chassis arrives tail, sintering deposit is unloaded under the control of tail star gear tooth plate and afterbody bend, return lower horizontal rails, carry out cycle of operation next time.
If traditional produced on-site pallet being done scaled down make laboratory simulation equipment, inevitably reduce fire grate bar size, this fire grate bar to newly developing assembles, middle simulated test test can not provide actual directive significance, use value is little, and preparing of the fire grate bar of scaled down version is extremely difficult, the pallet structure of scaled down version is the most complicated.
Existing furnace grid uses the problem of existence to include on sintering pallet: when the fracture of some furnace grid, local shedding, can cause local material leakage；After furnace grid fracture, local shedding; remainder branch loosens; when chassis runs and turns to sintering machine annular bend; the fire grate bar loosened can slide, tilt; adjacent some furnace grid avalanche types are caused to loosen, be scattered; sintering pallet bottom hollow out, it is necessary to shutdown, again supplementary furnace grid section, has a strong impact on sintering machine properly functioning.
Fire grate bar that is traditional or that newly develop is fit directly on large scale sintering machine trolley operation; its fracture, defect process cannot be observed, and, as long as rupturing, defect, entirety are scattered, pallet bottom hollow out; sintering machine can only be shut down or empty mistake, has a strong impact on production.
Have no that the open report of pallet fire grate bar assembling test analog, fire grate bar assembly simulation test method introduced by document at present.The pallet structure of scaled down version is complicated, run if desired for simulation actual field production pallet, also wanting distributing planetary gear, actuating device, structure is more complicated, and this is that the art has no pallet fire grate bar assembly simulation assay device and major reason.
Summary of the invention
It is an object of the invention to provide the grid section assembly simulation assay device of a kind of pallet stove, mainly solve currently without simulation sintering machine fire grate bar assembling and the technical problem of operating test device.The present invention simulates the assembling on sintering pallet under fire grate bar normal temperature condition, running status, trial-production for fire grate bar product is tested, observe the operation of the one group of fire grate bar assembled, local loosens, dropping situations, it is particularly suitable for simulating fire grate bar to be impacted the operating mode of breakage, provides foundation for the development of fire grate bar and mass application.
The present invention is to be achieved through the following technical solutions: the assembly simulation assay device of a kind of pallet fire grate bar, including: base, column, framework, clamp, securing member, bearing block, axle, rotating disk.Described base and two fixing connections of column bottom, base arranges multiple fixing hole.Arranging multiple reinforcement between described column bottom and base, column top is installed bearing block or arranges axis hole.Described framework is by angle steel or channel-section steel or steel plate the rectangular frame connect, with fire grate bar form fit, axle is installed at the center at its two ends, axle mates with bearing block or the axis hole on column top, rectangular frame two ends arrange clamp, securing member, and for stationary furnace grid section, the structure of rectangular frame both sides can the upper lower cantalever of clip fire grate bar, when framework rotates, the upper lower cantalever of fire grate bar can be suspended on framework.Described rotating disk is in transmission connection with the axle formation of framework one end, and with external power or manual rotation, drive rectangular frame is along axle Arbitrary Rotation, by the tangent line rotation actual around axle spinning movement simulation in situ.
The method have the benefit that: compared with the prior art, the invention have the advantage that entirely different with actual large-type sinterer trolley structure, but fire grate bar ruuning situation on large scale sintering machine trolley can be simulated, without running roller, baffle plate and planetary gear and operation track, also without making fire grate bar group rotate around sintering machine head end planetary gear tangent line and running the ring-type operating of track, rotated by the tangent line that spinning movement simulation is actual in situ around axle, utilize rotation to replace the operating of planetary circular orbit, simplify the structure of assay device.With simple framework and fixing chuck plate, utilize rotation to replace the operating of planetary circular orbit, the assembling of fire grate bar can be realized, run simulation, analogy method is flexible, trial-production for fire grate bar product is tested, it is not necessary to tests on large scale sintering machine trolley, reduces experimentation cost and risk.Being capable of simulating the operating mode that fire grate bar is impacted, observe the ruuning situation of the one group of fire grate bar assembled, the development for fire grate bar provides foundation.The present invention solve the art cannot observe fire grate bar run on large scale sintering machine trolley, rupture, the research puzzle of defect process.
