如图7所示，本发明冷焰火喷发设备中，作为向送料装置下料的连续下料装置1，包括用于储存金属粉末5的装料料斗14以及用于金属粉末下料的漏斗15，装料料斗14的下部与漏斗15的上部之间设有用于通过周向旋转将装料料斗14内的金属粉末5连续推送至漏斗15内的旋转下料机构。旋转下料机构安装于装料料斗14上。旋转下料机构的输出端朝向漏斗15内，漏斗15的输出端连通至送料通道4。另外，旋转下料机构包括用于连通装料料斗14和漏斗15的控制下料管16、沿控制下料管16轴向布置于控制下料管16内腔并用于通过旋转将装料料斗14内的金属粉末5连续送至漏斗15内的旋转下料辊17以及用于驱动旋转下料辊17旋转的下料驱动机构7。旋转下料辊17表面设有连续的螺旋状下料凸起构造和/或连续的螺旋状下料凹陷构造。通过下料驱动机构7驱动旋转下料辊17在装料料斗14内的金属粉末5中旋转，利用旋转下料辊17表面凹凸结构带动金属粉末5通过控制下料管16进入到漏斗15中，以此完成金属粉末5的下料。可以通过控制旋转下料辊17与控制下料管16之间的间隙控制金属粉末5的下料量。可以通过旋转下料辊 17的旋转速度控制金属粉末5的下料速度。可选地，下料驱动机构7采用输出端转速可调的减速电机。通过改变电机的输出转速，控制旋转下料辊17的旋转速度，从而控制金属粉末5的下料速度和下料量，以此改变冷焰火喷发的效果。
本实施例的冷焰火喷发设备，包括上述用于冷焰火喷发设备的送料装置。
根据上述冷焰火喷发设备，用于冷焰火喷发设备的送料装置包括丝杆503、送料通道4、陶瓷轴承13、链轮(链轮机构9)、链条(链轮机构9)以及送料驱动电机(送料驱动机构8)。丝杆503将漏斗(连续下料装置1)导引下来的金属粉末2送至加热装置点燃，并将点燃后的金属粉末2送至出口管中。送料通道4即可确保金属粉末2在丝杆503中的均匀性，也可为金属粉末2的点燃提供封闭空间。陶瓷轴承13采用氧化铝或氧化硅等陶瓷材料，用于固定丝杆503，并能避免热量的传递。减速电机(送料驱动机构8)通过链轮和链条(链轮机构9)驱动丝杆503，可使丝杆503平滑转动，减少噪声。
本实施例解决了金属粉末2不能充分点燃的问题。连续下料装置1下料的金属粉末2通过漏斗均匀、连续的分散在丝杆503表面和螺纹槽内，增加了金属粉末2与加热装置的接触面积，而且加热圈10的保温套管11的保温作用，可使丝杆503上加热区域内的温度恒定，因此确保了金属粉末2得到充分点燃。
本实施例解决了冷焰火喷发设备喷发时火焰不稳定和不连续的问题。丝杆503的丝杆结构，送料驱动电机(送料驱动机构8)的均匀转速，可将由漏斗滑落下来的金属粉末2均匀、连续的推送至加热装置内，通过控制丝杆503和送料管送料通道4之间的间隙以及控制丝杆503旋转的转速，可控制丝杆503推送金属粉末2的均匀性和连续性，进而控制火焰的稳定性和连续性。
本实施例解决了冷焰火装置加热时热量隔绝的问题。采用保温套管11和丝杆隔热垫圈(隔热垫圈12)可使加热圈10加热的热量密封在其 腔体内，不仅确保丝杆503上加热区域内的温度恒定，而且可杜绝热量传递其他区域，起到隔热作用。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
