Heat sinter after sintered, through the cooling of cooling device, cold fragmentation and the cold screening of multistage, could send into blast furnace and carry out ironmaking production.Usually the equipment cooled sintering deposit has central cooler and belt-cooling machine two kinds, but it all has air leak rate of air curtain high (40 ~ 50%), sintering deposit waste heat recovery rate low (10 ~ 40%), the shortcomings such as pollutant increase such as cooling exhaust quality lower (150 ~ 450 DEG C) and particle.For overcoming above shortcoming, utility model patent " a kind of high efficiency recovery unit of sintering waste heat resource " (number of patent application 201120219670.4) proposes vertical sintering waste heat retracting device, and national inventing patent the vertical sinter cooler of high efficiente callback sintering mine sensible heat " a kind of can " (number of patent application 200910074513.6), national inventing patent " method of residual heat resources in sintering process classification recovery and cascade utilization and device thereof " (number of patent application 200910187381.8) propose vertical sintering waste heat and reclaim and supporting device for generating power by waste heat.
Vertical sintering waste heat recovery system oval cross section blanking control method: in vertical sintering waste heat recovery system, when heat sinter is collected from sintering machine afterbody, after delivering to vertical sintering waste heat recovery tank body top access to plant, move from top to bottom under gravity, with the air inversion heat exchange entered from tank base, carry out heat recovery.The overall falling speed of sintering deposit controls by the seal valve openings of sizes of tank base and the vibration frequency of oscillating feeder.But for tank interior sintering deposit skewness, the change of sintering deposit discharge quantity and fluctuation, the situation of sintering deposit change of granularity, the size distribution fallen due to sintering deposit cannot be measured by effective method, the process that sintering deposit falls to carrying out heat exchange is very uncontrollable, very easily occur due to sintering deposit ore particle degree skewness, and then cause sintering deposit falling speed skewness, Bed Void skewness, air-flow velocity skewness, this is because the design itself of the precise controlling means shortcoming of sintering deposit vertical cooling tank body own and the air-out of the section of prestoring edge causes, cannot avoid, the heat trapping of vertical sintering waste heat recovery system creates very adverse influence with recovery, the heat causing sintering deposit can not reclaim effectively, cause the sintering deposit temperature of discharging higher or temperature is extremely uneven.This mainly owing to lacking efficient and that operating space is little blanking velocity local modulation device, makes sintering deposit even drop down, ensures to reach best heat transfer effect between heat sinter and air.This drawback seriously limits the application of vertical sintering waste heat retracting device and the popularization under multi-state.
Summary of the invention
The purpose of this utility model is the deficiency being difficult to adapt to the change of sintering deposit discharge quantity and fluctuation, sintering deposit change of granularity and temperature segregation for vertical sintering waste heat retracting device, provides a kind of oval cross section blanking adjusting device of vertical sintering waste heat recovery system.
Vertical sintering waste heat recovery system oval cross section blanking adjusting device comprises regulating rod, annulus platform, sintering deposit vertical cooling tank body lower cone section, bolt hole, bolt, and wherein regulating rod comprises oval section, changeover portion, cylindrical section, handle and coarse section; The oval section of regulating rod, changeover portion, cylindrical section are connected in turn; One end near changeover portion on cylindrical section is provided with coarse section, and the one end away from changeover portion is provided with handle; Sintering deposit vertical cooling tank body lower cone section comprises cone segments and the upper and lower two parts of cylindrical section, and be provided with multiple annulus platform perpendicular to cylindrical section outer surface, annulus platform and regulating rod form regulon by matched in clearance; Each annulus platform has three 120 ° of equally distributed screwed holes of being circumferentially separated by, be screwed into coarse section of close contact of bolt and regulating rod by screwed hole, with secured adjusted rod.
Described regulon is divided into four groups, and the four groups of regulating rods comprised all are positioned at sustained height at sustained height or relative direction two groups, and adjacent direction regulating rod is staggeredly arranged up and down; Often organizing regulating rod is one or more, all adopts circumference to be evenly arranged.
The utility model can make original vertical sintering waste heat retracting device adapt to the change of sintering deposit discharge quantity and the change of fluctuation, sintering deposit granularity, the effectively segregation of solution sintering deposit outlet temperature.Regulate at vertical sintering waste heat retracting device on the basis of air quantity and the overall feeding coal of sintering deposit and increase mineral aggregate blanking velocity local modulation device, the intrinsic deficiency that sintering deposit vertical cooling tank body particle size distribution control device is short of and the air-out of the section of prestoring edge causes heat exchange uneven can be overcome, adapt to the demand of multi-state and variable working condition, expand vertical sintering waste heat retracting device to the adaptability of multi-state.This ellipse bar rotation adjustment device relative pull-out type cylindrical cross-section regulating rod, effectively can reduce the operating space outside tank body simultaneously.
