请参阅图1至图12。需要说明的是，本实施例中所提供的图示仅以示意方式说明本发明的基本构想，遂图式中仅显示与本发明中有关的组件而非按照实际实施时的组件数目、形状及尺寸绘制，其实际实施时各组件的型态、数量及比例可为一种随意的改变，且其组件布局型态也可能更为复杂。
本发明提供一种转炉高位落料系统，具体如图1至图12所示，该转炉高位落料系统包括上料装置1，该上料装置1用于输送物料至高位料仓2；称重料仓3，该称重料仓3的进料口位于高位料仓2的出料口的下方，且在该称重料仓3的底部设有称重传感器(图中未示出)；物料加热炉4，该物料加热炉4的进料口41通过溜槽管道410与称重料仓3的出料口相连通，且在该称重料仓3的出料口处设有第一通断阀门，在该物料加热炉4上设有高温输气管道40，该高温输气管道40的排气端口4020与物料加热炉4的炉膛相连通，且在物料加热炉4上还设有排气口400；热风炉5，该热风炉5包括热风炉炉膛50和出风口51，热风炉炉膛50通过供气管道501与气源500相连通，该热风炉用于对热风炉炉膛50中的气体进行加热，出风口51与高温输气管道40的进气端口4010相连通；转炉6，所述物料加热炉4的出料口42通过落料溜槽420与转炉6相连通，且在该物料加热炉4出料口42处设有第二通断阀门。
采用本发明的转炉落料系统向转炉中添加废钢和金属球团时，废钢和金属球团在加入转炉6之前，会在物料加热炉4中进行预热，即通过热风炉5向物料加热炉4中输送高温气体，通过高温气体对物料加热炉4中的废钢和金属球团进行加热，将废钢和金属 球团加热到一定温度后打开物料加热炉出料口处的第二通断阀门，加热后的废钢和金属球团就会从物料加热炉4的出料口42落入到落料溜槽420中，然后通过落料溜槽420落入到转炉6中。与现有技术相比，本发明的转炉高位落料系统能够对加入转炉6中的废钢和金属球团进行提前预热，使得在转炉6中加入废钢和金属球团后减小了转炉中钢水的温降，提高了钢水的质量及产量。需要说明到的是，本发明的转炉高位落料系统不仅仅适用于向转炉中添加废钢和金属球团，在其他可选的实施方式中，本发明的转炉高位落料系统也可以根据实际需要适用于向转炉添加中其他物料。
优选的，在本实施例中，称重传感器与第一通断阀门电连接，当称重传感器检测到的重量数据达到重量阈值时，该称重传感器会向第一通断阀门发送控制信号，控制第一通断阀门自动开启。需要说明的是，在本实施例中，第一通断阀门为电动插板阀。
优选的，如图1至图3所示，该转炉高位落料系统还包括一换热器7，该换热器7包括换热腔70，且在该换热器7上设有进气口71和出气口72，该换热腔70与进气口71和出气口72均相连通，在该换热腔70内还设有蛇形管73。具体的，换热器7上的进气口71与物料加热炉4上的排气口400相连通，换热器7上的出气口72与除尘器8相连通，所述蛇形管73的一端与供气管道501的第一端相连通，该供气管道501的第二端与热风炉炉膛50相连通，蛇形管73的另一端与气源500相连通。考虑到从物料加热炉4中排出来的尾气其温度依然比较高，在本实施例中，通过在供气管道501与气源500之间设置一换热器7，使得物料加热炉4的排气口400排出的尾气经过该换热器7再排走，通过此结构设计，能够对物料加热炉4中排出来的尾气所含的热量进行再次利用，具有来讲，如图3所示，热风炉炉膛50中的气体是气源500通过供气管道501供送的，通过在气源500与供气管道501之间设置一换热器7，使得气源500供送的气体先通过换热器7内部的蛇形管73再通过供气管道501输送到热风炉炉膛50中，在此过程中，物料加热炉4排出的尾气经过该换热器7的换热腔70，温度较高的尾气在该换热腔70中会与蛇形管73中的气体进行热传递，即对向热风炉炉膛50中供送的气体进行了加热，从而使得供送到热风炉炉膛50中的气体是温度较高的气体，从而提高了热风炉5的热效率，能够大大降低加热热风炉炉膛中的气体所带来的燃料消耗，即很大程度上能够节约燃料消耗，降低系统的运行成本。在此，需要说明的是，在本实施例中，所述气源500为鼓风机，气源供送的气体即为空气，即从所述热风炉中加热出来的高温气体为高温空气。
进一步的，如图4至图6所述，所述热风炉5还包括烧嘴52和轴流风机53，该烧嘴52中通有燃气和助燃气用于点燃火焰对热风炉炉膛50中的气体进行加热，所述轴流 风机53用于将加热后的高温气体从热风炉5上的出风口51排出，该出风口51与高温输气管道40的进气端口4010相连通，通过该高温输气管道40输送到物料加热炉4的炉膛中对废钢和金属球团进行加热。通过在热风炉中设计一轴流风机能够将加热好的气体更好更舒畅的输送至物料加热炉4中。且在该实施例中，出风口51与高温输气管道40的进气端口4010通过一连接管相连通。具体的，该热风炉5上还设有热风炉观察口54，该热风炉观察口用于对热风炉5内部进行观察以及方便对热风炉5内部进行检修。在该热风炉5的底部还设有底座55，该底座55用于支撑整个热风炉5，且该底座55采用Q235-B材质制成。进一步的，为了提高该热风炉炉膛50的使用寿命，该热风炉炉膛的外壳采用Q235-B材质，且在该热风炉炉膛的内壁涂有重质浇注料，该重质浇注料起到隔热保温作用。需要说明的是，在本实施例中，该热风炉产生的高温气体能够达到500-550℃，即烧嘴52能够将热风炉炉膛50中的气体加热到500-550℃。在本实施例中，烧嘴52为直燃式烧嘴，烧嘴通的燃气和助燃气分别为煤气和空气。
优选的，如图7至图11所示，高温输气管道40包括高温输气主管道401和多个高温输气分管道402，该高温输气主管道401环绕物料加热炉4的外周设置，该高温输气主管道401通过多个高温输气分管道402与物料加热炉4的炉膛相连通。通过此结构设计，能够使得热风炉5供送的高温气体从多个方向进入到物料加热炉4的炉膛，从而可以对物料加热炉中的物料(废钢和金属球团)加热的比较均匀。即可以理解到，在本实施例中，所述高温输气管道40的进气端口4010只有一个即设置在高温输气主管道401上，高温输气管道40的排气端口4020有多个，即多个高温输气分管道402上均有一个排气端口4020。进一步的，为了使得对物料加热炉4中的废钢和金属球团加热的更加均匀，在本实施例中，多个高温输气分管402沿物料加热炉的周向方向均匀分布，具体的，在本实施例中，高温输气分管402设有四个，四个高温输气分管402分布设置物料加热炉4的四个侧面上。
优选的，如图7和图11所示，所述高温输气管40设置在物料加热炉4的底部，物料加热炉4上的排气口400设置在物料加热炉4的顶部，通过此结构设计，高温气体从物料加热炉4的底部进入物料加热炉的炉膛，然后从物料加热炉4的顶部排出，高温气体在物料加热炉4中由下向上充分对废钢和金属球团进行加热，能够提高高温气体的利用效率。进一步的，为了使得物料加热炉炉膛中的废钢和金属球团更加快速均匀的受热，在物料加热炉4的炉膛内设有一内胆43，该内胆43上均匀地设置由多个气孔430，所述内胆43与物料加热炉炉膛的内壁之间具有排气间隙431，所述高温输气管道40的排气端口4020位于所述排气间隙431中。通过此结构设计，高温气体分别从四个高温输 气分管道402上的排气端口4020排放到内胆43与物料加热炉炉膛的内壁之间的排气间隙431后，然后排放到排气间隙431中的高温气体会再从内胆43上的多个气孔430进入到物料加热炉炉膛的内部，从而可以使得高温气体更加分散更加均匀的进入到物料加热炉炉膛空间的每个部位，可以对物料加热炉炉膛中的废钢和金属球团加热的更加均匀。进一步的，在本实施例中，在内胆43的每个面上均匀的设有多排气孔，每排气孔中相邻的两个气孔430之间的横向间隔为50nm，上下相邻的两排气孔之间的纵向间隔为160nm，且每个气孔430的孔径为5mm。具体的，在本实施例中，所述内胆43的材质为高铬铸铁板，且其厚度为20mm，由于高铬铸铁板耐磨性高，所以可以提高物料加热炉的使用寿命长。
优选的，如图7所示，为了方便对物料加热炉4中的温度进行实时的监测，在本实施例中，在物料加热炉4上设有有热电偶44。更为优选的，在本实施例中该热电偶44与设置在物料加热炉4的出料口处的第二通断阀门电连接，当热点偶43监测到物料加热炉4中的温度达到设定数值时，该热电偶会给第二通断阀门发送控制信号，控制第二通断阀门自动开启。具体的，在本实施例中，所述第二通断阀门为电动插板阀。
进一步的，在物料加热炉4的上还设有泄爆阀45，当物料加热炉4内的压力过高时，可采用泄爆阀45来进行泄压，从而使得多余气体排出物料加热炉4，防止物料加热炉4炉膛内压力过高导致的危险。具体的，在物料加热炉4上还设有加热炉观察口46，该加热炉观察口46用于观察加热炉炉膛中的作业情况。所述物料加热炉4的外壳的材质为Q235-B，外壳的厚度为16mm，且在该物料加热炉的炉膛内壁涂有重质浇注料，该重质浇注料起到隔热保温作用，其厚度为200mm。
优选的，如图1所述，上料装置1包括轨架10、料斗小车11和驱动装置(图中未示出)，其中，轨架10的一端设置于地面上，轨架10的另一端设置于高位料仓2顶部，料斗小车11滑动设置在该轨架10上，驱动装置能够驱动该料斗小车11沿轨架10上下滑动。在输送物料(废钢和金属球团)时，先使得料斗小车11到达轨架10的底部及轨架10设置于地面的一端，然后在料斗小车11上装满物料后，通过驱动装置拉动料斗小车沿轨架10向上滑动到达轨架10的顶部即设置于高位料仓2顶部的一端后，料斗小车11会直接翻转将料斗小车里的物料倒入到高位料仓2中。通过此结构设计对物料进行输送，结构简单，方便快捷。进一步的，为了提高输送物料的效率，在轨架10上设有两台料斗小车11，即分别为第一料斗小车和第二料斗小车，两台料斗小车轮流进行装料和倒料，即当第一台料斗小车在轨架10的底部装料时，第二台料斗小车正好到达轨架10顶端将物料倒入高位料仓2中，然后通过驱动装置拉动第一料斗小车在轨架10的正面 沿轨架10向上移动，此时，第二料斗小车会在轨架10的反面沿轨架10向下移动。在本实施例中，所述驱动装置为卷扬机。
具体的，在本实施例中，在高位料仓的出料口处设有通断阀门，在日常使用过程中，在该高位料仓2中可预先储存物料(废钢和金属球团)，当需要向转炉6中加物料(废钢和金属球团)时，打开设置在高位料仓出料口处的通断阀门使得高位料仓2中的物料通过其出料口落料至下方的称重料仓中，此为现有技术，故在此不再详细进行赘述。
进一步的，为了防止高位料仓2落料时，物料塞堵中出料口，在本实施例中，在高位料仓出料口的通断阀门处还可以设置一振动给料机，该振动给料机能够使得高位料仓中的物料均匀的落至称重料仓中。优选的，在本实施例中，在称重料仓的出料口处及物料加热炉的出料口处也均设置有一振动给料机。
如图12所示，本发明还提供一种采用上述转炉高位落料系统的转炉高位落料方法，包括以下步骤：
S1、上料装置输送物料到高位料仓；
S2、所述高位料仓将物料落料至称重料仓，当称重传感器检测到称重料仓中的物料的重量达到重量阈值时，开启设置在所述称重料仓出料口处的第一通断阀，物料从所述称重料仓落料至物料加热炉；
具体的，在该步骤S2中，称重传感器与设置在称重料仓出料口处的第一通断阀电连接，且在称重传感器中预先设置有重量阈值，当称重传感器检测到落料至称重料仓中的物料的重量达到预先设置的重量阈值时，该称重传感器会给第一通断阀门发送控制信号，控制第一通断阀门自动开启，然后使得称重料仓中的物料落料至物料加热炉中。
S3、热风炉向所述物料加热炉供送高温气体对物料进行加热，当物料加热到设定温度时，开启设置在物料加热炉出料口的第二通断阀，加热后的物料从物料加热炉落料至转炉内。
具体的，在该步骤S3中，热风炉炉膛通过供气管与气源相连通，该热风炉对热风炉炉膛中的气体进行加热，然后加热后的高温气体从加热炉的出风口排入高温输气管道，然后通过高温输气管道输送到物料加热炉中对物料进行加热。
进一步的，考虑到从物料加热炉4中排出来的尾气其温度依然比较高，在本实施例中还包括：
S4、将物料加热炉中排放出来的尾气排入到换热器，所述换热器设置在气源与供气管道之间，所述换热器对气源输送至供气管道中的气体进行加热。
通过对物料加热炉中排放出来的尾气进行再次回收利用，即使其对向热风炉炉膛中 供送的气体进行了加热，从而使得供送到热风炉炉膛中的气体是温度较高的气体，从而提高了热风炉的热效率，能够大大降低加热热风炉炉膛中的气体所带来的燃料消耗，即很大程度上能够节约燃料消耗，降低系统的运行成本。
与现有技术相比，本发明的转炉高位落料系统及落料方法能够对加入转炉中的废钢和金属球团进行提前预热，使得在转炉中加入废钢和金属球团后减小了转炉中钢水的温降，提高了钢水的质量及产量。同时，通过对物料加热炉中排出来的尾气进行回收利用，使其对向热风炉炉膛中供送的气体进行了加热，从而使得供送到热风炉炉膛中的气体是温度较高的气体，从而提高了热风炉的热效率，能够大大降低加热热风炉炉膛中的气体所带来的燃气消耗，即很大程度上能够节约燃气消耗，降低了系统的运行成本。
综上所述，本发明的一种转炉高位落料系统及落料方法，解决了现有技术中废钢和金属球直接加入转炉导致钢水产量和质量降低的问题。同时，本发明的转炉高位落料系统及落料方法在不改变原有生产模式的情况下，其设备布置灵活，改造投资低，非常适合于现有的转炉工艺的节能改造。所以，本发明有效克服了现有技术中的种种缺点而具高度产业利用价值。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
