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组件10与加热板组件组合的方式对硫化室进行加热，其原理为电加热管组件10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。
加热板组件包括两个加热板20，两个加热板20分别设置在硫化腔的两侧，其中，电加热管组件10包括两个电加热管，两个电加热管分别设置在两个加热板20上，以给加热板20提供热量。电加热管设置在加热板20远离硫化腔的一侧。
如图1所示，本实施例中的加热板组件采用两个加热板20，分别设置在硫化腔的上端和下端，以同时给硫化腔内的生胎进行加热硫化，此外，为了方便控制温度，将电加热管设置在加热板20远离硫化腔的一侧，电加热管不会暴露在硫化腔内，加热板20在中间起到缓冲和散热更均匀的作用。
加热板20上设有安装槽，电加热管设置在安装槽内。
如图1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1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。
加热板20上还设有锁紧板30，锁紧板30用于将电加热管固定在安装槽内。加热板20为圆形板，电加热管沿加热板20的周向方向上环绕加热板20设置，锁紧板30沿加热板20的径向方向上延伸设置，以对电加热管的不同位置进行固定，锁紧板30为多个，多个锁紧板30沿加热板20的周向方向上间隔地设置。
如图1所示，在加热板20设置安装槽的一侧均布地设置了8个锁紧板30，8个锁紧板30沿加热板20的轴向方向间隔地设置，且每个锁紧板30沿着加热板20的径向方向延伸，通过螺丝固定在加热板20上，从而将电加热管压在安装槽内。
本申请还提供了一种硫化机，包括硫化室，其中，硫化室内设有硫化机加热装置，硫化机加热装置为上述的硫化机加热装置。
本申请的硫化机采用电加热的方式给硫化腔进行加热，更加节能环保。
硫化室还包括隔热板，隔热板设置在硫化机加热装置的加热板组件上远离硫化腔的一侧。
隔热板采用隔热材料，用于减少电加热管热量的流失，同时防止硫化室外侧温度过高，出现安全隐患等问题。
硫化机还包括：温度检测组件，温度检测组件设置在硫化腔内以检测硫化腔内的温度；控制器，控制器与硫化机加热装置的电加热管组件10控制连接，控制器还与温度检测组件连接，以接收温度检测组件检测的数据控制电加热管组件10的温度。
本实施例中温度检测组件采用温度传感器，温度传感器设置在硫化室内以用于检测硫化腔内的温度，当该温度低于预设值时，控制器加大电加热管组件10的功率，以使电加热管组件10产生更多的热量，当温度低于预设值时，控制器减小电加热管组件10的功率，从而给硫化腔进行降温，采用控制器控制电加热管的功率，能够快速敏捷的实现对硫化腔内温度的调节和控制，给轮胎提供更加稳定的硫化环境。
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：
本申请的硫化机加热装置的仅需在底面加工10mm的螺旋槽即可适用于安装电热管，对热板整体强度影响很小，故给热板的材质提供了可以优化的可能性，本申请的热板可以选用Q235系列板材作来替代现有的热板材质，更加节省成本，而原钻孔、焊接或铣槽式热板，由于需要形成蒸汽的流道，且理论上流道容积越大热量传导越好，故热板内形成的连续腔体降低了加热板20的强度，因此，为了保证加热板20的强度，需要选择强度更高的材料，导致成本较高。
为满足温度、温差的要求，单块加热板20还可以分成不同的区域，分别采用电加热管来加热到不同的温度，例如，将加热板20分内外两个温区，可以采用通过对于输入功率的控制调节的方式分别对电加热管进行加热，采用单独或集成于PLC的温控模块，在设定温度条件下实现温度的自动调节控制，有效的减小了热板及上下热板的温差。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
