Description
本实用新型涉及了一种用于由耐火材料构筑的炼焦炉的封闭装置，具体为一种可开闭的炼焦炉炉盖。
目前，在我国应用比较多的土焦炉，从炉顶结构看，大致包括两大类，一类属敞顶式或无盖式，以萍乡炉为代表，这种炉型装料与出焦比较方便，缺点是燃烧不均，焦碳质量不稳定，付产品如焦油，煤气回收利用率低，造成非常严重的污染，为了克服上述不足，近年又设计出一种具有炉顶结构的土焦炉，也称封闭式炼焦炉，如中国专利CN87212113U公开的一种“炼焦炉”，其构成是由耐火砖及青磁砖砌筑的四面侧壁墙支撑一个由同样材料构筑的拱型炉顶，在拱型顶上设有配风兼进煤孔，在拱型顶上还设置了与左右侧壁墙、炉底回火道相通的回火道上孔，这种炉型的缺点是，由于炉顶采用耐火材料砌筑成整体固定形式，在炼焦与熄焦等不同阶段，因温差变化很大，炉顶受热胀冷缩影响，容易造成裂缝以至塌顶，从而大大影响焦炉寿命，其次，由于进煤主要通过炉顶进料口，造成进煤不便，时间增加，且难以对原料进行夯实，也影响焦碳质量；第三，这种炉型散热慢，熄焦周期长，出焦时炉内温度较高，增加了工人劳动强度。
本实用新型的目的在于避免上述不足，提供一种即便利进料与出焦，易于夯实、又可防止烟尘向大气排放，污染环境，且不会造成炉顶塌陷的可开闭的炼焦炉炉盖。
本实用新型是这样实现的：该炼焦炉炉盖由多个可分离的拱型小盖组合构成，各小盖与炉体的侧壁采用活动联接，各分离的拱型小盖与炉体侧壁的活动联接为由在各拱型小盖两端安装的滚动轮和在炉体两侧壁设置的长度大于炉体长度与滚动轮配合的轨道构成。
所述的可分离的拱型小盖，各小盖还可以在其一端设有带连接孔的盖脚，盖脚上的连接孔和与炉体侧壁钢性固定且带有连接孔的炉盖底座上的连接孔相配合，并通过钢销而构成与炉体侧壁的活动联接。
构成本实用新型所述的炉盖的各拱形小盖内侧有附着齿，便于耐火材料的固定，在盖上还开有散热孔。
本实用新型的优点是：进料与出焦较为方便；缩短了结焦时间；便于对原料进行夯实；减轻了对环境的污染；完全避免了由于热胀冷缩造成的炉顶塌陷。

图10是本实用新型的第二实施例
实施例1，本实施例描述的炼焦炉炉盖由多个拱形的小盖5组合构成，各小盖与炉体侧壁，2，采用活动联接，当炉盖闭合时，各分离的小盖拼成一完整的炉盖，小盖5下部有两只带连接孔9的盖脚12，小盖5的盖脚12上的连接孔9和与炉体侧壁内固定的与炉体侧壁等长的槽钢7固连的小盖底座8上的连接孔16相配合，并通过钢销15构成各小盖与炉体侧壁的活动联接，在各小盖的内侧设有附着齿13，以增加耐火材料14附着炉盖内侧的牢固性，并在其上开有散热孔11，在拱形小盖靠上部设有一吊环6，便于小盖的开闭，当炉盖需要张开时，可使用小型卷扬机通过拱形小盖上部所设的吊环6将小盖逐个吊起，需闭合时，做相反操作即可。
实施例2：本实施例所述的炼焦炉炉盖由若干节拱形小盖组成，在小盖两端安装有滚动轮17，在炉体两侧壁设置有长度大于炉体长度的轨道18，拱形小盖两端的滚动轮17和轨道18配合构成炉盖与炉体侧壁的活动连接，炉盖可通过推拉各节拱形小盖进行开启和关闭。
本实用新型所述的拱形小盖可直接铸造或焊接而成。
