Description
本发明涉及一种窑，尤其涉及一种独立控制窑炉排烟的结构。
现有窑炉的排烟方式，在产品上方、下方支管的废气一般集中到窑顶的一根主管后从排烟风机排出，由于支管调节时相互干扰大，使窑压不稳定，同时窑内截面温差也大，导致产品色差、变形、开裂等。另外，窑顶上部的排烟结构，几乎都是在窑顶开孔，然后将抽烟罩或抽烟顶部支管插入窑顶的孔洞内，由于窑头烟气中含二氧化硫等腐蚀性气体和粉尘、水蒸汽等杂质，并且温度较高，使用一段时间后，管道、阀门容易生锈，并且容易集粉，当温度波动冷热交替大或调节阀门产生震动时，支管铁锈或粘结物会间歇性地脱落到产品表面，经高温烧结后，形成“落脏”、“熔洞”等缺陷，降低产品合格率。
本发明目的在于提供一种独立控制窑炉排烟的结构，以解决现有技术中所存在的一个或多个技术问题，至少提供一种有益的选择或创造条件。
本发明解决其技术问题的解决方案是：
一种独立控制窑炉排烟的结构，包括窑体与排烟风机，所述窑体内具有产品上方通道与产品下方通道，所述窑体顶部设置有上排烟主管，所述上排烟主管上设置有多条上支烟管，所述上支烟管连通于所述产品上方通道，所述窑体底部设置有下排烟主管，所述下排烟主管上设置有多条下支烟管，所述下支烟管连通于所述产品下方通道，所述上排烟主管与所述下排烟主管均连通于所述排烟风机的进风端。
该技术方案至少具有如下的有益效果：在窑顶和窑底分别设置有上排烟主管与下排烟主管并由排烟风机抽风，使产品的上、下方可独立控制烟气量，减少相互干扰，同时沿窑体的长度延伸方向排列多条支烟管，即上排烟主管通过多条上支烟管连接至窑体内，下排烟主管通过多条下支烟管连接至窑体内，可根据窑体内产品上部、下部、截面的温度情况分别增加或减少排烟量，从而改变气流、温度场，解决温差问题，有效降低产品缺陷率。
作为上述技术方案的进一步改进，所述上支烟管与所述窑体之间设置有过渡烟道，所述过渡烟道固定于所述窑体的顶侧，所述过渡烟道内设置有与所述产品上方通道相互连通的气流通道，所述上支烟管远离所述上排烟主管的一端连接于所述过渡烟道的侧壁，所述上支烟管通过所述气流通道连通于所述产品上方通道。用于进行导风的上支烟管在实际使用中通常是使用金属材质，在长时间使用后容易出现生锈、集灰等问题，而此处独立设置的过渡通道则可以使用非金属材质，有效避免了因侵蚀而造成的生锈等问题，将上支烟管连接至过渡烟管的侧壁上，即使上支烟管存在脏物也不会直接落入到窑内产品上，进一步降低产品缺陷率。
作为上述技术方案的进一步改进，所述窑体的顶侧设置有吊顶砖，所述吊顶砖上设置有凹槽，所述凹槽的底面设置有保温毯，所述过渡烟道的底端固定于所述保温毯上。将过渡烟道固定在凹槽内，可降低窑体内烟气向外流失，并且利用保温毯放置于过渡烟道与吊顶砖之间，进下减少热量的散失。
作为上述技术方案的进一步改进，所述过渡烟道包括轻质砖，所述轻质砖围拢形成所述气流通道。过渡烟道主要由轻质砖砌成，上支烟管连接至该轻质砖砌成的墙体侧壁上。
作为上述技术方案的另一种改进，所述过渡烟道包括保温棉与固定板，所述保温棉围拢形成所述气流通道，所述固定板位于所述保温棉的内侧，所述固定板上设置有螺栓并将所述保温棉拉紧至所述固定板上。过渡通道主要由保温棉围拢而成，而固定板则将保温棉的内外侧通过螺栓拉紧，并对整体起到固定作用，通过固定板将整体固定在窑体的顶侧。
作为上述技术方案的进一步改进，所述固定板为重质耐火板。可避免固定板在长时间使用后产生生锈、脱锈的问题。
作为上述技术方案的进一步改进，所述下支烟管的顶端设置有通气帽。通气管可防止窑体内的物体直接掉落至下支烟管内，对下支烟管起到保护作用。
作为上述技术方案的进一步改进，所述上排烟主管或所述上支烟管上设置有第一冷进风口。外设的冷风装置可通过第一冷进风口向上排烟主管或上支烟管内部送入冷风，使抽出的烟气温度有所降低，从而延长管道的使用寿命。
作为上述技术方案的进一步改进，所述下排烟主管或所述下支烟管上设置有第二冷进风口。同样的，外设的冷风装置可通过第二冷进风口向下排烟主管或下支烟管内部送入冷风，使抽出的烟气温度有所降低，从而延长管道的使用寿命。
作为上述技术方案的进一步改进，所述排烟风机设置有不少于一台。在产量较大的窑体中，可采用多台排烟见机，在窑体的头部设置一台，在窑体的中后部设置一台，使得排烟抽力更大，管内气体干扰更小，调节窑压更加灵活。
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单说明。显然，所描述的附图只是本发明的一部分实施例，而不是全部实施例，本领域的技术人员在不付出创造性劳动的前提下，还可以根据这些附图获得其他设计方案和附图。
图1是本发明的整体正视结构示意图；
图2是本发明的上支烟管与过渡烟道连接示意图；
图3是本发明的整体侧视结构示意图。
附图中：100-上排烟主管、110-上支烟管、120-过渡烟道、200-下排烟主管、210-下支烟管、300-排烟风机、400-窑体、410-吊顶砖、420-保温毯。
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整地描述，以充分地理解本发明的目的、特征和效果。显然，所描述的实施例只是本发明的一部分实施例，而不是全部实施例，基于本发明的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本发明保护的范围。另外，文中所提到的所有连接关系，并非单指构件直接相接，而是指可根据具体实施情况，通过添加或减少连接辅件，来组成更优的连接结构。本发明创造中的各个技术特征，在不互相矛盾冲突的前提下可以交互组合。
参照图1与图3，一种独立控制窑炉排烟的结构，包括窑体400与排烟风机300，所述窑体400内具有产品上方通道与产品下方通道，所述窑体400顶部设置有上排烟主管100，所述上排烟主管100上设置有多条上支烟管110，所述上支烟管110连通于所述产品上方通道，所述窑体400底部设置有下排烟主管200，在实际使用中，由于下排烟主管200直径大，为降低操作面高度，将下排烟主管200安装于地坑内，所述下排烟主管200上设置有多条下支烟管210，所述下支烟管210连通于所述产品下方通道，所述上排烟主管100与所述下排烟主管200均连通于所述排烟风机300的进风端。
由上述可知，在窑顶和窑底分别设置有上排烟主管100与下排烟主管200并由排烟风机300抽风，使产品的上、下方可独立控制烟气量，减少相互干扰，同时沿窑体400的长度延伸方向排列多条支烟管，即上排烟主管100通过多条上支烟管110连接至窑体400内，下排烟主管200通过多条下支烟管210连接至窑体400内，可根据窑体400内产品上部、下部、截面的温度情况分别增加或减少排烟量，从而改变气流、温度场，解决温差问题，有效降低产品缺陷率。
为了进一步降低窑内产品的缺陷率，如图2所示，所述上支烟管110与所述窑体400之间设置有过渡烟道120，所述过渡烟道120固定于所述窑体400的顶侧，所述过渡烟道120内设置有与所述产品上方通道相互连通的气流通道，所述上支烟管110远离所述上排烟主管100的一端连接于所述过渡烟道120的侧壁，所述上支烟管110通过所述气流通道连通于所述产品上方通道。用于进行导风的上支烟管110在实际使用中通常是使用金属材质，在长时间使用后容易出现生锈、集灰等问题，而此处独立设置的过渡通道则可以使用非金属材质，有效避免了因侵蚀而造成的生锈等问题，将上支烟管110连接至过渡烟管的侧壁上，即使上支烟管110存在脏物也不会直接落入到窑内产品上，进一步降低产品缺陷率。
为了提高过渡烟道120与窑体400的连接密封效果，所述窑体400的顶侧设置有吊顶砖410，所述吊顶砖410上设置有凹槽，所述凹槽的底面设置有保温毯420，所述过渡烟道120的底端固定于所述保温毯420上，形成曲封结构，将过渡烟道120固定在凹槽内，可降低窑体400内烟气向外流失，并且利用保温毯420放置于过渡烟道120与吊顶砖410之间，进下减少热量的散失。
作为对过渡烟道120的实施例一，所述过渡烟道120包括轻质砖，所述轻质砖围拢形成所述气流通道。过渡烟道120主要由轻质砖砌成，上支烟管110连接至该轻质砖砌成的墙体侧壁上。
作为对过渡烟道120的实施例二，所述过渡烟道120包括保温棉与固定板，所述保温棉围拢形成所述气流通道，所述固定板位于所述保温棉的内侧，所述固定板上设置有螺栓并将所述保温棉拉紧至所述固定板上，螺栓的另一端将保温棉固定在窑体400框架上。过渡通道主要由保温棉围拢而成，而固定板则将保温棉的内外侧通过螺栓拉紧，并对整体起到固定作用，通过固定板将整体固定在窑体400的顶侧。
作为对实施例二的进一步改进，所述固定板为抗烟气腐蚀、热稳定性好的重质耐火板。可避免固定板在长时间使用后产生生锈、脱锈的问题。
为了保持下支烟管210的通畅性，所述下支烟管210的顶端设置有通气帽。通气管可防止窑体400内的物体直接掉落至下支烟管210内、杂物等碎屑掉落阻塞下支烟管210，对下支烟管210起到保护作用。
从窑体400内抽出的烟气温度非常高，在长时使用下容易对上排烟主管100或上支烟管110的结构造成损坏，因此，在本实施例中，所述上排烟主管100或所述上支烟管110上设置有第一冷进风口。外设的冷风装置可通过第一冷进风口向上排烟主管100或上支烟管110内部送入冷风，使抽出的烟气温度有所降低，从而延长管道的使用寿命。
同样的，所述下排烟主管200或所述下支烟管210上设置有第二冷进风口，外设的冷风装置可通过第二冷进风口向下排烟主管200或下支烟管210内部送入冷风，使抽出的烟气温度有所降低，从而延长管道的使用寿命。
在一些实施例中，所述排烟风机300设置有不少于一台。在产量较大的窑体400中，可采用多台排烟见机，在窑体400的头部设置一台，在窑体400的中后部设置一台，使得排烟抽力更大，管内气体干扰更小，调节窑压更加灵活。
以上对本发明的较佳实施方式进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
