Description

冷火焰喷发设备
本申请要求于2020年1月20日提交中国专利局、申请号为202010067208.0、名称为“冷火焰喷发设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及舞台造景设备技术领域，尤其涉及一种冷焰火喷发设备。
背景技术
为了活跃舞台气氛、装点舞台背景，人们常常通过燃放冷焰火来提升舞台效果。
现在技术也存在利用金属粉末下料机构持续供应金属粉末、利用激发金属粉末的方式进行持续产生冷焰火的冷焰火喷发设备，然而现有的冷焰火下料存在金属粉末下料稳定性难以控制、下料存在间断性的问题，不能够连续下料，造成冷焰火的喷发效果不可控，而且最关键的是下料速度慢，不能满足冷焰火的快速喷发需求。
因此，提供一种能瞬间喷发的冷焰火喷发设备，将燃点较低的金属粉末定量、迅速的送至加热区并点燃，使下料过程快速、可控，大约在一秒内就能加热并点燃金属粉末，达到冷焰火快速喷发的需求，从而带给人们绝佳的视听感受，更好地烘托舞台气氛，已经成为本领域技术人员亟待解决的技术问题。
发明内容
本发明的目的是提供一种冷焰火喷发设备，能够快速、定量地使燃料到达加热区，以满意快速喷发的需求。
为实现上述目的，本发明提供了一种冷火焰喷发设备，包括设有送料螺杆的送料管，所述送料管的内端部开设有向上的金属粉末下落口，所述 金属粉末下落口和料斗之间具有金属粉末下落通道，所述金属粉末下落通道中设有能够将该通道关闭和导通的开关装置；所述送料管的外端部连通喷花管，所述喷花管的底端连接开关阀。
优选地，所述开关装置包括顶部与所述料斗的出料口配合、底部与所述金属粉末下落口配合的接料漏斗，以及工作端位于所述接料漏斗之中的开关板；所述开关板水平设置且能够受驱动沿其水平轴线移动；所述开关板抽离出料口时所述金属粉末下落通道导通，所述开关板遮挡出料口时所述金属粉末下落通道关闭。
优选地，所述开关板由电磁铁驱动且能够往复水平运动，所述电磁铁安装于电磁铁安装板。
优选地，所述开关装置包括顶部与所述料斗的出料口配合、底部与所述药剂下落口配合的接料漏斗，以及工作端位于所述接料漏斗之中的开关套；所述开关套水平设置且能够受驱绕其水平轴线转动，其工作端具有垂直于该水平轴线且贯通的下料口；所述下料口竖向时所述药剂下落通道导通，所述下料口水平时所述药剂下落通道关闭。
优选地，所述喷花管的底端通过开关阀连接压力罐，所述压力罐还连接充气泵。
优选地，所述压力罐还设有安全阀和压力传感器。
优选地，所述喷花管的底端通过开关阀连接压力气源。
优选地，所述送料管的内端部伸入所述喷花管之中，且所述喷花管的外侧设有保温隔热外壳。
本发明所提供的冷焰火喷发设备具有以下优点：
1、由于在送料管中设置了送料螺杆，可以更为迅速地将金属粉末输送至预定位置，显著提高了喷发的速度，可以实现在一秒之内完成喷发过程。
2、由于在金属粉末下落通道中设置了开关装置，通过对通道导通时间的控制即可使进入送料管中的金属粉末数量更准确。
3、同样由于在金属粉末下落通道中设置了开关装置，前次喷发之后阻止了金属粉末提前进入送料管中，避免了下次喷发之前提前进入的金属粉末被氧化，而金属粉末被氧化正是下次喷发尤其是间隔时间较长的下次喷 发达不到预期效果的原因；基于这个问题的发现，本申请所提供的送料点燃机构能够可靠地实现快速喷发，即使喷发时距离前次喷发的时间较长也仍然能够实现，快速喷发的可靠度得到了大幅提高。
此外，在进一步的方案中，所述喷花管的底端通过开关阀连接压力气源。这样，由于外界压力气源的压力持续、稳定，可以不必等待充气泵为压力罐恢复充气的时间，设备喷发不但响应速度快，而且喷发间隔也短，能够为舞台效果提供更大的设计空间。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。

图2为图1所示设备的俯视示意图；
图3为图1中送料点燃机构处于金属粉末下落通道关闭状态的结构示意图；
图4为图1中送料点燃机构处于金属粉末下落通道导通状态的结构示意图。
图5为另一种送料点燃机构处于金属粉末下落通道关闭状态的结构示意图；
图6为图5中送料点燃机构处于金属粉末下落通道导通状态的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没 有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明核心是提供一种冷焰火喷发设备，能够定量、快速地使燃料到达加热区，并能够可靠地满足快速喷发的需求。
请参考图1-图4，图1为本申请一种具体实施方式所提供冷焰火喷发设备的结构示意图；图2为图1所示设备的俯视示意图；图3为图1中送料点燃机构处于金属粉末下落通道关闭状态的结构示意图；图4为图1中送料点燃机构处于金属粉末下落通道导通状态的结构示意图。
在第一种具体实施方式中，本发明提供的冷焰火喷发设备包括送料管4，送料管4的作用是将金属粉末输送至预定的位置，然后由加热线圈6进行加热点燃后，再由喷花管7喷出。
送料管4的内端部可伸入喷花管7之中，且喷花管7的外侧设有保温隔热外壳8。
送料螺杆3设置于送料管4之中，并能够在驱动部件的作用下绕其轴线自转，从而将金属粉末自送料管4的内端部向外端部输送。在图中送料管4的左端为其内端部、右端为其外端部。
送料螺杆4可以由送料电机1驱动，两者通过联轴器2连接，送料电机1可以安装于送料电机安装板。
送料管4的内端部开设有金属粉末下落口，用于承接自上方落入的金属粉末。
金属粉末首先自料斗5进入机构，然后经由料斗5的底部开口进入金属粉末下落通道，然后可以由该金属粉末下落通道的底部进入所述金属粉末下落口之中。
金属粉末下落通道中设有开关装置，所述开关装置可以选用适宜的具体结构，只要能够在需要时将该金属粉末下落通道关闭，并在需要时将其导通即可。
具体而言，所述开关装置可以按照以下方式设置：
设置接料漏斗17，使接料漏斗17的顶部与料斗5的出料口配合，以承接下落的金属粉末；其底部显然应与所述金属粉末下落口良好配合。
在接料漏斗17之中(例如其空间较大的上部)设置开关板16，开关板16大致水平设置，且能够在驱动部件的作用下让其沿水平轴线移动。
开关板16可以由电磁铁14驱动，电磁铁14可以安装于电磁铁安装板15。
在开关板16受驱移动的过程中，当电磁铁14断电时，料斗5的出料口将被开关板16的工作端封堵，因此所述金属粉末下落通道关闭；当电磁铁14通电时，所述料斗5的出料口处无遮挡，因此所述金属粉末下落通道导通。
喷花管7的底端可以通过开关阀10(例如电磁阀)连接压力罐9，压力罐9还可以连接充气泵13，在完成喷发后可以为下次压力罐9补充压力，以完成下次喷发。
送料电机1、电磁铁14以及开关阀10等可以均连接控制模块，这样可以使开关板16、送料螺杆4以及压力罐9能够按照预定的时间关系动作。
压力罐9还可以设置安全阀11和压力传感器12。
请参考图5和图6，图5为另一种送料点燃机构处于金属粉末下落通道关闭状态的结构示意图；图6为图5中送料点燃机构处于金属粉末下落通道导通状态的结构示意图。
在另一种具体实施方式中，可以在接料漏斗17之中设置由开关电机19驱动的开关套18，以使开关套18旋转90°时打开时所述金属粉末下落通道导通，开关套18反向旋转90°时所述金属粉末下落通道关闭。当然，也可以驱动开关套18每次同向转动90度，也可实现上述切换过程，在此情况下具体可以实现的结构请参考现有技术，本申请不再赘述。
本发明所提供的冷焰火喷发设备具有以下优点：
1、由于在送料管中设置了送料螺杆，可以更为迅速地将金属粉末输送至预定位置，显著提高了喷发的速度，可以实现在一秒之内完成喷发过程。
2、由于在金属粉末下落通道中设置了开关装置，通过对通道导通时间的控制即可使进入送料管中的金属粉末数量更准确。
3、同样由于在金属粉末下落通道中设置了开关装置，前次喷发之后阻止了金属粉末提前进入送料管中，避免了下次喷发之前提前进入的金属粉 末被氧化，而金属粉末被氧化正是下次喷发尤其是间隔时间较长的下次喷发达不到预期效果的原因；基于这个问题的发现，本申请所提供的送料点燃机构能够可靠地实现快速喷发，即使喷发时距离前次喷发的时间较长也仍然能够实现，快速喷发的可靠度得到了大幅提高。
为了能够实现连续喷发，喷花管7的底端还可以通过开关阀连接压力气源。
这样，由于外界压力气源的压力持续、稳定，可以不必等待充气泵为压力罐恢复充气的时间，设备喷发不但响应速度快，而且喷发间隔也短，能够为舞台效果提供更大的设计空间。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
以上对本发明所提供的冷焰火喷发设备进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
