Description
Technical field
the present invention relates to a kind of monitoring equipment, particularly a kind of coke oven coal briquet whole process shrinks monitoring equipment.
Background technology
coking is the main task of coke-oven plant, and coking produce be stabilized in affect by coke pushing current to a great extent very large.Analyze at coke oven thermal technology management aspect, whether coke oven heating system is reasonable, can cause very large impact to coke pushing current.Coke pushing current is large, not only affect coke oven and equipment life, if secondary Jiao occurs to produce coking furnace shaft especially, the wound of unrepairable, if occurrence of large-area coke pushing is difficult, coking can be made especially to produce and to be absorbed in pause, upsetization produces operation, has a strong impact on converter life, causes coke and coal gas amount significantly to decline, threaten steel mill normally to produce, enterprise produced and causes the economic loss that cannot estimate! From the analysis of causes causing coke pushing current bigger than normal, primarily of cause influences such as proportioning, heating, bodies of heater, and proportioning and heating are the most difficult analyses.
Summary of the invention
the object of the present invention is to provide a kind of can the checkout equipment of continuous coverage coke shrinkage, effectively instruct coke making and coal blending than formulating, proportion optimizing structure.
the present invention adopts following technical scheme:
a kind of coke oven coal briquet whole process shrinks monitoring equipment, comprise tactile disk, monitoring rod, host computer, tactile disk is placed on coke oven coal briquet, be connected with test rod above tactile disk, the blind end of the other end of test rod through outer cylinder body and to inner barrel extends, and outer cylinder body is built with liquid, and the opening end of inner barrel is placed in below the liquid level of outer cylinder body, the blind end of inner barrel is equipped with scale and detecting element, and detecting element is connected with host computer by data line.
adopt the present invention of technique scheme compared with prior art, can determine that briquette can expand contraction change process because there is melting, solidification, formation semicoke and coke by scale relative to the change in location of rule, thus effectively instruct coke making and coal blending than formulating, proportion optimizing structure, reduces the loss.
preferred version of the present invention is:
the barrel of outer cylinder body side is provided with extension plate, and extension plate is provided with rule.
be connected and fixed cover above the blind end of inner barrel, fixed cover is equipped with scale, fixed cover is equipped with adjusting screw(rod), detecting element is equipped with on the top of adjusting screw(rod).
gland bonnet is equipped with test rod between outer cylinder body bottom and tactile disk, the hole or be connected except carbon pores of coalingging of gland bonnet and carbonization chamber.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
Embodiment
below in conjunction with drawings and Examples in detail the present invention is described in detail:
a kind of coke oven coal briquet whole process shrinks monitoring equipment, see in accompanying drawing 1, figure: tactile disk 1, test rod 2, outer cylinder body 3, inner barrel 4, adjusting screw(rod) 5, fixed cover 6, detecting element 7, scale 8, rule 9, data line 10, host computer 11, gland bonnet 12, extension plate 13.
in the present embodiment, tactile disk 1 is placed on coke oven coal briquet, the top of tactile disk 1 is connected with test rod 2, the blind end of the other end of test rod 2 through outer cylinder body 3 and to inner barrel 4 extends, and outer cylinder body 3 is built with water, and the opening end of inner barrel 4 is placed in below the liquid level of outer cylinder body 3, cover 6 is connected and fixed above the blind end of inner barrel 4, fixed cover 6 is equipped with the scale 8 of horizontally set, fixed cover 6 is equipped with adjusting screw(rod) 5, detecting element 7 is equipped with on the top of adjusting screw(rod) 5; Detecting element 7 is connected with host computer 11 by data line 10.Adjusting screw(rod) 5 for regulation scale 8 relative to the height in rule 9 measurement range.
the barrel of outer cylinder body 3 side is provided with extension plate 13, extension plate 13 is provided with longitudinal rule 9.
gland bonnet 12 is equipped with test rod 2 between outer cylinder body 3 bottom and tactile disk 1, the hole or be connected except carbon pores of coalingging of gland bonnet 12 and carbonization chamber.
the present embodiment truly can judge that whether coke oven heating is reasonable, instructs coking to produce further, analyzes and Problems existing in the formulation process of research proportioning, to instruct coke making and coal blending than the detection analytical equipment of the work such as formulation and proportion optimizing.
utilize collecting device (monitoring frequency can be made by oneself) that Monitoring Data is depicted as curve simultaneously and carry out data analysis, according to the charge of coke dilation curve checked, utilize stepper motor and papery output interface, or utilize industrial computer, the equipment such as displacement transducer, its process is shown in host computer, the ultimate range demonstrating the decline of maximum contraction a(briquette accounts for the percentage of briquette height, i.e. maximum contraction), the ultimate range that maximum dilatation b(briquette rises accounts for the percentage of briquette height, i.e. maximum dilatation), (time that briquette starts to shrink accounts for the percentage of briquette coking cycles to beginning shrinkage value τ, i.e. beginning shrinkage value τ), after maximum contraction rate λ m(briquette starts contraction, the ratio of degree of shrinkage and time, namely value when shrinkage factor is the fastest, i.e. maximum contraction rate λ m) and final shrinkage factor λ e(briquette coking 1.5h in latter stage in, the number very much of the briquette degree of shrinkage that every 30 points of kinds are measured, i.e. final shrinkage factor λ e), can be understood completely by above index, briquette expansion, contraction change in whole coking coking cycles, reliable data foundation is provided for reasonably formulating heating cycle (standard temperature), optimize coke oven temperature to control, the data such as proportioning contraction, expansion can also be reflected simultaneously, and then instruct coking to produce, judge to cause the reason that the large or difficulty of coke pushing current pushes away.
when coking utilizes this checkout equipment, if side coal needs artificial flat coal, or top dress is after coke oven pushing car put down coal, utilize stoke hole or carbon removal hole site, just installing on the carbonization chamber of coal, place this measuring equipment, all information of charge of coke change can be detected, finally can carry out relative to the change in location papery output interface of scale 9 or at host computer 11 display that both pictures and texts are excellent by scale 8.
the principle of work of patent of the present invention:
utilize briquette in coke oven coking cycles, become in coke process by coal, briquette can expand contraction change process because there is melting, solidification, formation semicoke and coke, and the temperature treatment of these variation characteristics and coke oven, mixting ratio factor have direct relation, can not only indicate and reflect coke oven heating information and briquette proportioning information by these characteristics, coke oven can also be instructed to produce and proportioning work.
