针对现有的一次性燃放的冷焰火筒需经电气连接控制点火头装置产生火花点燃火药，由于有火药的存在，该冷焰火筒在生产、运输以及燃放过程中均存在一定的危险性；并且冷焰火均是一次性燃放，并且存在喷发时间短、焰火喷发时间不可操控以及冷焰火筒不可循环利用等诸多弊端的技术问题，本实施例的一个方面，提供一种新型的冷焰火喷发设备。
参照图1，本实施例提供一种冷焰火喷发设备，该冷焰火喷发设备包括：下料机构1、送料机构2、加热机构3、喷发机构4，下料机构1设有用于将金属粉末5连续推送至送料机构2内的下料辊轴13及驱动下料辊轴13旋转的下料驱动电机(图中未示出)；送料机构2包括送料管21，送料管21内设有用于将金属粉末5连续推送至喷发机构4的送料丝杆22，送料丝杆22连接驱动送料丝杆22旋转的送料驱动电机23；加热机构3套设于送料管21上，用于对送料管21内的金属粉末5进行加热；喷发机构4设有喷发口41及风机42，风机42用于将经送料机构2输出且在加热机构3加热后点燃的金属粉末5经喷发口41喷出以形成冷焰火。
参照图1，本实施例下料机构1包括用于储存金属粉末5的装料料斗11以及用于金属粉末5下料的下料漏斗12，装料料斗11的下部与下料漏斗12的上部之间设有用于通过周向旋转将装料料斗11内的金属粉末5连续推送至下料漏斗12内的下料辊轴13，下料辊轴13安装于装料料斗11上，下料辊轴13的输出端朝向下料漏斗12内；下料漏斗12的输出端连通至用于将金属粉末5加热并送至下一工序的送料管21，下料辊轴13连接有驱动其旋转的下料驱动电机，在下料驱动电机的作用下，利用下料辊轴13旋转体的表面凹凸结构带动金属粉末5朝向下料漏斗12方向移动，进而连续带动金属粉末5下料。本实施例下料机构1能够保证金属粉末5输送的连续性和均匀性，输送过程中不存在金属粉末5输送停顿的现象。并且通过稳定的旋转以及旋转体表面状况的恒定性，使得输送过程中的金属粉末5输送量始终保持恒定，使得输送至冷焰火喷发的金属粉末5始终保持定量和定速，能够很好的控制冷焰火的喷发效果，更好的展现冷焰火的舞台效果。本实施例下料漏斗12的输出端直接连接送料管21，使得定速定量获得的金属粉末5可以及时的输送至下一工序，保证冷火焰喷发的有序进行，不会造成金属粉末5的堆积和卡停。可选地，装料料斗11采用上大下小的倒锥形结构，从而保证金属粉末5的输出效率。
本实施例送料机构2包括与下料漏斗12的出口端连通的送料管21， 送料管21内设有沿送料管21轴向布置并用于通过周向旋转将经下料机构1下落的金属粉末5连续推送至喷发机构4的送料丝杆22，送料丝杆22的外表面设有连续的螺旋状凸起构造和/或连续的螺旋状凹陷构造，且送料丝杆22在送料驱动电机23的带动下旋转，通过送料丝杆22表面的螺旋状凸起构造和/或连续的螺旋状凹陷构造形成送料管21内轴向上的推送力，从而对金属粉末5产生持续不断的推送力，并且迫使金属粉末5始终贴合于送料管21的内壁面上，从而保证对金属粉末5送料的连续性和均匀性。通过对送料丝杆22旋转速度的控制，即可轻易的实现冷焰火喷发效果的控制，从而很好的展现冷焰火在舞台上的可视效果。
本实施例加热机构3优选地为套设于送料管21外壁上的加热圈，该加热圈沿送料管21的轴向布置，使金属粉末5在送料过程中能够持续得到升温。可选地，送料丝杆22的外径尺寸可以与送料管21的内壁面尺寸相同，使得金属粉末5可以均匀的分布于丝杆结构的各个槽内，从而得到充分的加热。可选地，送料丝杆22的外径尺寸可以小于送料管21的内壁面尺寸，使得送料丝杆22周围的金属粉末5容量更多，从而形成更大量的喷发效果。
本实施例中，可选地，加热圈之外套设有用于保温和防止热量外泄的保温套管31。优选地，送料管21的至少一端设有用于保温和防止热量外泄的隔热垫圈32。这样，可使加热圈加热的热量密封在保温套管31与隔热垫圈32形成的腔体内，不仅确保送料丝杆22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。
如图1所示，本实施例中，喷发机构4设有喷发口41及风机42，风机42用于将经送料机构2输出且在加热机构3加热后点燃的金属粉末5经喷发口41喷出以形成冷焰火。本实施例中，喷发口41与风机42处于同一轴线上，且该轴线与送料管21的轴线垂直。本实施例中，风机42采用热风机，能够有效降低金属粉末5的冷却速度，提高冷焰火的喷射效果。通过控制风机的转速，可以动态改变冷焰火的喷发高度。
金属粉末5可以采用燃点低的金属粉末，按一定比例加工混合而成。 优选地，金属粉末5可以采用铝、铁、锶、镁、钙、锆、铜、钛中的至少一种金属粉末；或金属粉末5可以采用铝、铁、锶、镁、钙、锆、铜、钛中的至少一种金属化合物粉末。可选地，金属粉末5也可以采用上述金属粉末与上述金属化合物进行混合的混合粉末。金属粉末5在送料机构2中被输送的过程中由加热机构3逐渐加热成高温状态(达到燃点)，在从送料管21输出后与风机42产生的气流(空气)接触而被点燃，点燃的金属粉末5在风机42产生的气流的带动下经喷发口41喷出以形成冷焰火。
本实施例冷焰火喷发设备，通过采用下料机构1实现了金属粉末5的连续稳定下料，且通过送料机构2与加热机构3的配合，在送料过程中对金属粉末5进行加热以点燃金属粉末5，且经喷发机构4的风机42将点燃的金属粉末经喷发口41喷出，以形成冷焰火，整个过程无需装入火药，燃放安全且无污染烟雾产生，金属粉末喷射后即迅速冷却熄灭，不会造成任何安全隐患。只要金属粉末原料充沛，能够持续的进行喷发；并且能够反复的装料和喷发使用。这种冷焰火喷发设备可以适用于各种室内外舞台、甚至家居环境内部使用。
