- the grate 10 is directly connected to the support column 30 of the steel structure by bolts. Since the incinerator is operated, the combustion air is blown into the grate 10 for combustion, and the combustion causes the grate 10 to thermally expand to press the support columns 30 on both sides, so that stress occurs in the steel structure. When the size of the steel structure is large enough, the superposition of the externally applied stress and the static stress may exceed the allowable stress range of the steel structure, thereby compromising the safety performance of the steel structure.

- the incinerator of the present invention has the following beneficial effects: With the incinerator of the present invention, when the combustion waste inside the grate is thermally expanded, the pillars fixed thereon are moved on the horizontal support member, The thermal stress of thermal expansion is released and converted into a thrust effect that pushes the strut to move over the horizontal support. Therefore, the thermal stress is eliminated, and the supporting column steel structure supporting the grate is not subjected to the stress applied by the grate, thereby ensuring the stability of the steel structure.

说明书
Title of Invention:一种焚烧炉
技术领域
[1] 本实用新型涉及焚烧炉领域， 更具体地说， 涉及一种可减少应力的焚烧炉。
背景技术
[2] 目前垃圾焚烧已逐渐成为城市生活垃圾处理的主要途径， 其中的焚烧炉是垃圾 焚烧的关键设备， 它对垃圾物料起到支撑和输送作用， 通过对垃圾物料的搅拌 和混合， 以及对引入的助燃空气的均匀分配， 使燃烧充分进行， 设备可靠运行
[3] 在通常的设计中， 如图 1所示， 焚烧炉包括内部进行燃烧垃圾的炉排 10以及支 撑炉排的支撑柱 30， 其为钢结构。 炉排 10通过螺栓直接连接到钢结构的支撑柱 3 0上。 由于焚烧炉工作吋炉排 10内吹入助燃空气以进行燃烧， 燃烧造成炉排 10热 膨胀从而挤压两侧的支撑柱 30， 使得钢结构内出现应力。 当钢结构的尺寸足够 大吋， 所受的外部施加的应力与静态应力的叠加可能超出钢结构的许用应力范 围， 从而危及钢结构的安全性能。
发明内容
[4] 本实用新型要解决的技术问题在于， 针对现有技术的上述钢结构支撑柱受到炉 排膨胀的热应力的挤压使其内应力增大的缺陷， 提供一种消除炉排内应力从而 保护钢结构的焚烧炉。
[5] 本实用新型解决其技术问题所釆用的技术方案是： 构造一种焚烧炉， 包括炉排 和位于所述炉排两侧的支撑柱， 还包括固定安装在所述炉排两端随其热膨胀而 向外移动的支柱和固定安装在所述支撑柱上的水平支撑件， 所述支柱放置在所 述水平支撑件上。
[6] 在本实用新型所述的焚烧炉中， 所述水平支撑件为两端分别固定安装在两侧支 撑柱上的横梁。
[7] 在本实用新型所述的焚烧炉中， 所述支柱的下端底面位于所述水平支撑件的上 表面上， 且直接接触摩擦。
[8] 在本实用新型所述的焚烧炉中， 所述支柱的下端底面位于所述水平支撑件的上 表面上， 且所述支柱底面垫有便于在所述水平支撑件上移动的滑片。
[9] 在本实用新型所述的焚烧炉中， 所述支柱有两根， 分别位于所述炉排的左、 右 两侧， 且分别靠近所述水平支撑件的左、 右两端端面。
[10] 在本实用新型所述的焚烧炉中， 所述支柱靠近所述水平支撑件的两端端面且与 所述支撑柱之间隔有间隙。
[11] 实施本实用新型的焚烧炉， 具有以下有益效果： 釆用本实用新型的焚烧炉， 当 炉排内部燃烧垃圾吋热膨胀， 将带动其上所固定的支柱在水平支撑件上移动， 则将热膨胀的热应力释放且转化为推动支柱在水平支撑件上移动的推力作用。 因此， 热应力得到消除， 支撑炉排的支撑柱钢结构不会受到炉排所施加的应力 ， 从而保证钢结构的性能稳定。
附图说明
[12] 下面将结合附图及实施例对本实用新型作进一步说明， 附图中：
[13] 图 1是现有技术的焚烧炉结构示意图；
[14] 图 2是本实用新型优选实施例的焚烧炉的结构示意图。
具体实施方式
[15] 如图 2所示， 本实用新型优选实施例的焚烧炉包括炉排 10、 水平支撑件 40、 支 撑柱 30、 支柱 20。 其中， 炉排 10左、 右两侧各安装有一个支柱 20， 炉排 10的下 方为横梁形状的水平支撑件 40， 且支柱 20的下底表面与水平支撑件 40的上表面 接触， 水平支撑件 40的两端分别固定在炉排 10两边的支撑柱 30上。 水平支撑件 4 0用于承载其上的炉排 10、 炉排 10内的垃圾以及支柱 20的重量。 支撑柱 30为钢结 构， 支撑焚烧炉其他所有组成部件的重量。
[16] 支柱 20的下端底面停在水平支撑件 40上， 并未与水平支撑件 40固定连接或者安 装， 而是可以在水平支撑件 40上表面上相对水平支撑件 40水平移动。 水平支撑 件 40的上表面为水平面， 支柱 20在其上实现水平移动的方式有多种， 如支柱 20 的下端底面直接与水平支撑件 40上表面接触， 或者在支柱 20底面安装便于移动 的摩擦系数小的滑片、 安装滚轮等。 其中一个具体方式为在支柱 20底面与水平 支撑件 40之间安装滑板， 所述滑板包括与支柱 20底面固定连接的上滑板、 与水
平支撑件 40固定连接的下滑板。 其中， 上滑板与下滑板相接触的表面上打磨光 滑， 或者在接触面上设置油道注入润滑油， 以减小二者之间相对滑动吋的摩擦 力。 本实用新型并不仅限于此， 任何可以实现支柱 20在水平支撑件 40上相对水 平移动的方式均属于本实用新型保护范围之内。 水平支撑件 40上还可设置有防 止支柱 20侧翻、 侧覆的档位结构， 如水平支撑件 40的上表面为' U'形的凹面， 而 不是光滑的水平面， 则支柱 20置于凹面的底部， 而凹面两侧的竖直板即为档位 结构， 能起到防止支柱 20侧翻、 侧覆的作用。 还有其他实现方式， 本文不作赞 述。
[17] 两个支柱 20分别位于靠近水平支撑件 40左、 右两端的位置， 但其并不是处于水 平支撑件 40两端尽头端面上， 而是与水平支撑件 40的两端端面还有一段较小的 距离。 水平支撑件 40的两端端面则直接固定安装在左、 右两侧的支撑柱 30上。 也就是说， 支柱 20与相应一侧的支撑柱 30之间留有一段间隙， 间隙的宽度大于 支柱 20随炉排 10热膨胀而向两侧滑移的滑移量。
[18] 当炉排 10内垃圾燃烧， 则炉排 10温度升高， 则炉排 10热膨胀， 体积向两侧会有 一定的扩张。 在传统的焚烧炉结构中， 由于炉排 10直接固定到支撑柱 30的钢结 构上， 则炉排 10膨胀而向两侧挤压钢结构， 使钢结构内应力增大， 再加上钢结 构本身所存在的静态应力共同作用， 如果超出了钢结构的许用应力范围， 会影 响钢结构的安全性能。
[19] 而在本实用新型的优选实施例中， 结合图 2可知， 炉排 10体积向两侧扩张吋， 当炉排 10热膨胀的应力大于支柱 20与水平支撑件 40之间的静摩擦力， 则支柱 20 在水平支撑件 40上滑动， 炉排 10推动支柱 20向水平支撑件 40的两端移动； 而支 柱 20与支撑柱 30之间已留有间隙， 允许这种水平移动的进行。 因此炉排 10的热 膨胀的内应力转化为支柱 20的移动， 而没有转嫁到钢结构上而影响钢结构的性 能， 而炉排 10的热应力也得到消除。
[20] 当然， 本实用新型并不仅限支柱 20分别位于炉排 10左、 右两侧， 可在其它热膨 胀明显的侧面增设支柱 20且可向外滑动； 也不仅限左、 右各一根支柱 20， 为了 保证炉排的稳固， 也可以增设两根或者多根支柱 20， 或者也相应增加水平支撑 件 40的数量以适应两根或多根支柱 20所需的宽度。
上面结合附图对本实用新型的实施例进行了描述， 但是本实用新型并不局限于 上述的具体实施方式， 上述的具体实施方式仅仅是示意性的， 而不是限制性的 ， 本领域的普通技术人员在本实用新型的启示下， 在不脱离本实用新型宗旨和 权利要求所保护的范围情况下， 还可做出很多形式， 这些均属于本实用新型的 保护之内。
