Description

硫化室及硫化机
本申请要求于2021年9月30日提交至中国国家知识产权局、申请号为202111163783.1、发明名称为“硫化室及硫化机”的专利申请的优先权。
技术领域
本申请涉及硫化机技术领域，具体而言，涉及一种硫化室及硫化机。
背景技术
轮胎硫化机热板作为硫化机关键部件之一，为轮胎硫化过程传递热量、压力，目前的轮胎硫化剂热板多采用导热油或蒸汽对热板进行加热，但两种方式存在以下缺点：
1、无论是导热油还是蒸汽，提供热量的介质需要泵站生成并加热至工艺温度后输送至硫化室，输送过程造成大量热能损耗，造成能源的极大浪费，不节能、不环保；
2、采用导热油或蒸汽加热时，热板上介质流入一端的温度要明显高于介质流出一端的温度，加热不均匀，影响硫化后轮胎的质量，且在采用蒸汽加热时，热板内介质由于蒸汽的冷凝特性导致加热不均匀，热板温差大，影响硫化后轮胎质量。
3、为了提供较高的热量，需要在热板内形成较大的密封腔，以容纳尽量多的加热介质，对密封要求较高且密封腔会造成热板结构强度不好，且导热油和蒸汽的温度不方便调节。
4、过热水及蒸汽对于管道、阀门的腐蚀，造成的渗漏等，形成了生产单位备品配件及能源的极大成本投入。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
请参考图1至图3，一种硫化室，包括胶囊，硫化室还包括输气通道和第一加热组件51，输气通道与胶囊连通，以通过向胶囊内输送气体使胶囊膨胀；第一加热组件51设置在输气通道上，以对向胶囊输送的气体进行加热。
本申请的硫化室摒弃了向胶囊内充入高温蒸汽以给胶囊加热的方式，通过直接给充入胶囊内的氮气进行加热的方式提高胶囊的温度，具体的，胶囊内通入氮气以使胶囊膨胀以给轮胎的内侧施加压力，在氮气输气通道上设置第一加热组件51，直接给氮气进行加热来提高胶囊的温度，取消了现有的蒸汽通道和热油通道，使的整个硫化室结构更加简单，同时也取消了产生蒸汽的装置和存放热油的油箱，节约了能源。
根据一种实施例，第一加热组件可以设置为多个，多个第一加热组件可选择地设置在输气通道上，以对输气通道内的气体进行加热，其中，输气通道内的气体可以是氮气或空气等等。

本申请的硫化室底部还设有中心机构，中心机构能够驱动胶囊移动，为了方便向胶囊内输送气体，将驱动胶囊移动的上支撑杆52设计成中空的杆，使得该上支撑杆52在驱动胶囊移动的同时还能够通过内部的通道向胶囊内输送气体。
上支撑杆52顶部设有出气口521，第一加热组件51设置在出气口521处。出气口521为多个，多个出气口521环绕在上支撑杆52的顶部间隔地设置。第一加热组件51采用电加热丝加热，电加热丝缠绕在上支撑杆52上。
本申请在上支撑杆52的顶端设置了一圈出气口521，为了便于固定电加热丝，采用将电加热丝缠绕在出气口521位置的方式，从而使的氮气在经过出气口521时通过电加热丝的加热温度升高，进而对胶囊进行加热。
硫化室还包括保护套53，保护套53罩设在电加热丝的外侧。该保护套53采用耐高温的材料，且保护套53具有隔热作用，防止电加热丝与胶囊直接接触，进一步，保护套53上设有多个孔以用于出气。
硫化室还包括环座缸组件60，环座缸组件60设置在上支撑杆52上，其中，硫化室还包括支撑组件，支撑组件设置在环座缸组件60上，其中，第一加热组件51固定在支撑组件上。支撑组件包括：多个立柱，多个立柱环绕出气口521设置以围成一个环形空间，其中，第一加热组件51缠绕在多个立柱的外侧，以对环形空间进行加热。

请参考图3，一种硫化机加热装置包括加热板组件和电加热管装置，加热板组件设置在硫化室内，以给硫化室的的硫化腔进行加热；电加热管装置设置在加热板组件上，以给加热板组件提供热量。
本申请采用了电加热的方式来给硫化腔进行加热，节能环保，同时解决了之前蒸汽加热时需要设置锅炉导致的成本高和占用空间大的问题，具体的，本申请的硫化机加热装置采用电加热管装置与加热板组件组合的方式对硫化室进行加热，其原理为电加热管装置先给加热 板组件进行加热，将加热板组件加热到一定的温度来给硫化腔提供热量，加热板组件能够更加均匀的给硫化腔的各个位置进行加热，减少了硫化腔内局部温差大的问题，该硫化机加热装置加热效率高，方便控制。
如图3所示，为了配合将电加热管安装在加热板20远离硫化腔的一侧，本实施例中将安装槽也设置在加热板20远离硫化腔的一侧，电加热管直接卡在安装槽内，本实施例中的安装槽沿着加热板20的径向方向由外向内一圈圈的布设，布设形状有多种，可以采用螺旋形的布置方式，也可以采用图3中一圈圈的往复折返布置，其目的是为了确保加热板20均匀受热。
此外，上述安装槽还可以分成多段，相适应地，电加热管也分为多段，一一对应地镶嵌在安装槽内，本实施例中电加热管采用柔性管，能够随安装槽的延伸方向进行变化，电加热管内部设有电加热丝，外部采用透明的柔性材料包裹。

硫化室还包括硫化室护罩，硫化室护罩包括第三护罩43、第一护罩41和第二护罩42，第一护罩41与第一模具连接，第二护罩42与第二模具连接；第三护罩43可伸缩地与第一护罩41和/或第二护罩42连接，以在第一模具和第二模具连接时，使第一护罩41通过第三护罩43与第二护罩42连接，以形成硫化空间。
本申请提供了一种用于密封模具的硫化室护罩，该硫化室护罩沿竖直方向上分为三部分，依次为第一护罩41、第三护罩43和第二护罩42，第三护罩43与第一护罩41连接时，第三护罩43能够相对第一护罩41相对滑动伸缩，第三护罩43与第二护罩42连接时，第三护罩43能够相对第二护罩42滑动移动，当第一模具和第二模具闭合时，第一护罩41通过第三护罩43与第二护罩42密封连接，以将第一模具和第二模具密封在护罩内，本申请的硫化室护罩能够根据不同模具的规格在高度方向上可调节伸缩，适用性更好。
当第一护罩41、第三护罩43和第二护罩42密封连接后，在第一护罩41或第二护罩42上还设有真空阀，打开真空阀以对硫化室护罩内侧的空间抽真空。
第三护罩43套设在第一护罩41的外侧，以沿第三护罩43的轴向方向相对第一护罩41移动。
如图2所示，本实施例中的第三护罩43为圆筒状结构，套设在第一护罩41的外侧，并能够相对第一护罩41上下滑动。
第一护罩41和第三护罩43之间设有第一密封圈411，以使第一护罩41和第三护罩43密封连接，其中，第一护罩41或第三护罩43上设有密封槽，以用于安装第一密封圈411。第三护罩43或第二护罩42上设有第二密封圈，以使第二护罩42通过第二密封圈与第三护罩43连接。

从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
本申请的硫化室摒弃了向胶囊内充入高温蒸汽以给胶囊加热的方式，通过直接给充入胶囊内的氮气进行加热的方式提高胶囊的温度，具体的，胶囊内通入氮气以使胶囊膨胀以给轮胎的内侧施加压力，在氮气输气通道上设置第一加热组件51，直接给氮气进行加热来提高胶囊的温度，取消了现有的蒸汽通道和热油通道，使的整个硫化室结构更加简单，同时也取消了产生蒸汽的装置和存放热油的油箱，节约了能源。
本申请的热板分为上热板和下热板，结构相同，在热板体加工螺旋槽，将电热管镶嵌入热板体内，电热管采用220V或380V电压控制，满足不同功率控制的电热效率，加以先进的温控模块，实现对加热板20预热、保温、损耗提温、预防峰值等的自动控制，实现热板温差±1.5℃。
为保证加热板20温度均匀性及热量损失，在加热板20与底座之间设置绝缘层及隔热层，同时圆周方向外部使用折合护罩保温，防止热量损失。
内温氮气由中心机构设置电热管的方式加热，根据氮气量、温度要求计算电热能转换，选择电热管功率，满足轮胎硫化的热量需求。
内外温管道可剔除所有蒸汽管道：外温管道全部取消，内温管道取消蒸汽管道，保证氮气的流通即可。
本申请的热板结构简练，易于加工制作，电加热板20无需加工宽槽、无需焊接，内部空腔减小提升了加热板20强度，则热板材质可选用普通牌号材料，降低制造成本。
本申请的硫化室蒸汽能取消，提升了轮胎企业建厂效率，取消蒸汽能代表着蒸汽锅炉的取消，大大降低了企业的投资成本，同时，由于锅炉容量与轮胎产量的配置比，取消锅炉后，可满足“星型工厂”的建设，而不会受制于锅炉容量。
此外，取消蒸汽能大大便捷了生产使用，无蒸汽管道阀门，维护保全人工及配件费用减低；无跑冒滴漏现象，硫化车间整体环境大大优化。
本申请的加热板20还可以采用电磁原理进行加热。
