Description

一种生产超厚岩棉板的固化炉
技术领域
本发明涉及岩棉生产设备技术领域，具体涉及一种生产超厚岩棉板的固化炉。
背景技术
岩棉作为一种无机的外墙保温材料，在建筑行业得到了空前的发展和广泛的应用。岩棉产品均采用优质玄武岩、白云石等为主要原料，经1450℃以上高温溶化后采用国际先进的四轴离心机高速离心成纤维，同时喷入一定量粘结剂、防尘油、憎水剂后经集棉机收集、通过摆锤法工艺，加上三维法铺棉后进行固化、横向切割以及纵向切割，形成不同规格和用途的岩棉产品。在岩棉生产过程中需要对岩棉纤维喷洒具有黏连性较强的胶水等物质从而使岩棉纤维粘连在一起，在通过进一步加工形成各种岩棉产品，固化炉是通过温度和气体流通使喷洒过的胶水等产品达到快速固化的。传统的岩棉生产线一般产量在2.5万吨以下，固化炉幅宽一般为1.2米，基于生产设备和生产工艺限制，岩棉板的厚度大都在150mm以下，超过150mm厚度的岩棉目前很难生产，对于较厚岩棉板的需求则无法满足。
发明内容
针对上述问题，本发明的目的是提供一种生产超厚岩棉板的固化炉，在提高生产的岩棉厚度的同时保证了岩棉的质量。
为实现上述目的，本发明采用如下技术方案：
一种生产超厚岩棉板的固化炉，包括机架、上链板和下链板，所述上链板上部固定设有提升装置，提升装置与上链板之间通过连接轴固定连接，提升装置两端固定设于机架两侧；所述提升装置为蜗轮蜗杆变速器，所述蜗轮蜗杆变速器包括固定在机架两端的涡轮和两涡轮之间的变速箱，变速箱与涡轮之间通过涡轮连接轴连接，所述涡轮连接轴的直径为100-140mm。
所述提升装置涡轮连接轴的直径为120mm。
所述上链板和下链板之间设有热风循环系统。
所述热风循环系统包括四个部分，从固化炉进料口至固化炉出料口分别为第一区、第二区、第三区和第四区，所述第一区的风压为950-1000KPa，第二区的风压为3800-4200KPa，第三区的风压为4300-4700KPa，第四区的风压为4800-5200KPa。
所述热风循环系统包括风机和燃烧室，燃烧室内采用全氧燃烧，全氧燃烧的原料为天然气和纯氧，天然气和纯氧的流量比例为1：（2-2.5）。
本发明与现有技术相比，本发明固化炉顶部设置的提升装置的涡轮连接轴直径增大，涡轮连接轴长度加长，在涡轮作用下，涡轮连接轴上下运动，进而带动固化炉上链板的运动，以完成岩棉的固化，该固化炉可将生产的岩棉厚度提高到300mm左右，满足20万吨左右的大产量岩棉生产线的需求，另外固化炉内的热风循环系统有效的为固化炉提供适当的风压和温度，保证岩棉板在增厚的同时不影响其固化质量。
附图说明
图1为本发明的结构示意图。
具体实施方式
为使本领域的技术人员对本发明更好地理解，下面结合具体实施方式对本发明做进一步说明：
如图1所示，一种生产超厚岩棉板的固化炉，包括机架2、上链板3和下链板1，所述上链板3上部固定设有提升装置，提升装置与上链板3之间通过连接轴5固定连接，提升装置两端固定设于机架两侧；所述提升装置为蜗轮蜗杆变速器，所述蜗轮蜗杆变速器包括固定在机架两端的涡轮7和两涡轮7之间的变速箱4，变速箱4与涡轮7之间通过涡轮连接轴6连接，所述涡轮连接轴6的直径为100-140mm；随着提升装置的上升和下降运动，完成岩棉板的固化，避免了提升装置的左右晃动，保证岩棉板的固化平整度以及固化质量，同时蜗轮蜗杆变速器可有效的增大提升装置的提升高度，以提高固化的岩棉板的厚度，满足生产超厚岩棉板的需求。
根据实际需要，所述涡轮连接轴6的直径设为120mm。
所述上链板3和下链板1之间设有热风循环系统，根据固化炉中需要固化的岩棉厚度以及宽度调节固化炉内的风压和温度，以使固化炉内保持最佳的固化温度和风压，保证超厚岩棉的固化质量。
所述热风循环系统包括四个部分，从固化炉进料口至固化炉出料口分别为第一区10、第二区11、第三区12和第四区14，所述第一区10的风压为950-1000KPa，第二区11的风压为3800-4200KPa，第三区12的风压为4300-4700KPa，第四区14的风压为4800-5200KPa。随着岩棉的不断进入固化炉，所受温度和压力不断升高，以渐变的温度和压力使岩棉逐渐脱水，提高岩棉的固化质量，避免因岩棉增厚而使岩棉内部与外部除湿效果不同而影响岩棉板的质量。
所述热风循环系统包括风机9和燃烧室8，燃烧室8内采用全氧燃烧，全氧燃烧的原料为天然气和纯氧，天然气和纯氧的流量比例为1：（2-2.5）。风机将从燃烧室内加热燃烧后的气体送入固化炉，以给固化炉提供所需要的风压和温度，同时热风循环系统中的压力传感器和温度传感器、风机以及天然气和纯氧的流量控制阀均与控制系统连接，利用PLC控制系统控制天然气和纯氧的流量以及风机的转速，保证热风循环系统中的风压和温度处于所要求的范围内。
根据实际生产中岩棉日产量的需求，所述上链板3和下链板1的宽幅设为3.6米，上链板3的底部上部以及下链板1的顶部下部均设有三条同步链条13，可将上链板3和下链板1的受力均匀分散至同步链条和托链，降低两端传动链轮的受力强度，同时避免了上链板和下链板中间部分在固化岩棉过程中变形，保证了岩棉的整体固化质量。
