如图1、图2、图3、图9、图10、图14和图15所示,本实施例中,送料装置2包括用于从下料装置1接收连续下落的金属粉末5并将金属粉末5送至喷发装置4的送料通道201。送料通道201上开设有与下料装置1的下料口106对应布置的进料口202。送料通道201内设有沿送料通道201轴向布置并用于通过周向旋转将从下料装置1下落的金属粉末5连续推送至喷发装置4的旋转送料辊203。旋转送料辊203的外表 面设有连续的螺旋状送料凸起构造204和/或连续的螺旋状送料凹陷构造205(参照图11-图13)。可选地,送料装置2连有用于驱动送料装置2运行的送料驱动机构b。送料装置2通过下料口106与进料口202的对应布置,使得连续从下料装置1下落的金属粉末5可以直接、稳定的进入送料通道201并落于旋转送料辊203的外表面,通过旋转送料辊203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通道201内轴向上的推送力,形成对金属粉末5持续不断的推送力,螺旋状凸起构造和/或连续的螺旋状凹陷构造旋转带动金属粉末5由进料口202向喷发装置4的点燃区域稳定地、持续地进行推送,从而保证对金属粉末5送料的连续性和均匀性。通过对旋转送料辊203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。
如图11-图13所示,本实施例中,螺旋状送料凸起构造204的径向尺寸相同或者径向尺寸从进料口202向喷发装置4方向逐渐减小;和/或螺旋状送料凹陷构造205的径向尺寸相同或者径向尺寸从进料口202向喷发装置4方向逐渐增大。能够减小旋转送料辊203对送料通道201壁体的作用力,能够提高送料通道201的使用寿命。
如图1、图9和图14所示,本实施例中,加热机构3包括紧贴于送料通道201外壁面的加热圈301。加热圈301从进料口202向喷发装置4方向分布。加热圈301采用交变电加热,或采用电磁感应加热,且其外套设有用于保温和防止热量外泄的保温套管302。送料通道201的至少一端设有用于保温和防止热量外泄的隔热垫圈303。
可选地,旋转送料辊203采用辊体径向尺寸完全相同的圆柱形直辊,据此推送力能够保持恒定,从而使得金属粉末5的输送能够均匀和稳定。可选地,旋转送料辊203采用辊体径向尺寸由进料口202向喷发装置4方向逐渐减小的变截面辊,这样使得旋转送料辊203施加到金属粉末5的推送力从进料口202向喷发装置4方向由大到小的变化,能够提高对金属粉末5的推送效率,也能够提高金属粉末5的利用率,有效防止在送料通道201内堆积。可选地,螺旋状送料凸起构造204的径向尺寸均 相同,据此推送力能够保持恒定,从而使得金属粉末5的输送能够均匀和稳定。可选地,螺旋状送料凸起构造204的径向尺寸由进料口202向喷发装置4方向逐渐减小,这样使得旋转送料辊203施加到金属粉末5的推送力从进料口202向喷发装置4方向由大到小的变化,能够提高对金属粉末5的推送效率,也能够提高金属粉末5的利用率,有效防止在送料通道201内堆积。可选地,螺旋状送料凹陷构造205的径向尺寸均相同,据此推送力能够保持恒定,从而使得金属粉末5的输送能够均匀和稳定。可选地,螺旋状送料凹陷构造205的径向尺寸由进料口202向喷发装置4方向逐渐增大,这样使得旋转送料辊203施加到金属粉末5的推送力从进料口202向喷发装置4方向由大到小的变化,能够提高对金属粉末5的推送效率。可选地,旋转送料辊203采用丝杆。据此,结构简单,推送力能够保持恒定,从而使得金属粉末5的输送能够均匀和稳定。
如图1、图14和图15所示,本实施例中,喷发装置4包括用于通过气流带动点燃后的金属粉末5喷发的出口管401。出口管401包括用于连通风机402的出风口的进口端4011、用于接收并点燃高温状态的金属粉末5的点燃部4012、用于将点燃后的金属粉末5喷发出去的喷发部4013以及用于向外喷发冷焰火的喷口4014。点燃部4012与喷发部4013同轴布置。点燃部4012的第一端(下端)通过进口端4011连通风机402的出风口。点燃部4012的第二端(上端)连通喷发部4013的第一端(下端),喷发部4013的第二端(上端)通过喷口4014连通外界。送料装置2的输出端从点燃部4012的侧壁连通至点燃部4012内。出口管401的内壁面上设有至少一层用于防止金属粉末5粘附于出口管401内壁面并且耐高温的防粘层403。喷发装置4通过设置出口管401形成冷焰火喷口,出口管401的一端连通风机402,通过风机402向出口管401内鼓风,形成气流通道,经过加热后的金属粉末5送入到出口管401内会被点燃并随着气流通道向外喷发,从而形成冷焰火的喷发效果。通过在出口管401的内壁面粘附依用于防止高温的金属粉末5粘附于出口管401内的防粘层403,消除了出口管401由于点燃金属粉末5产生的结瘤而造成的堵塞。可选地,风机402采用转速可调的风机,以控制冷焰 火的喷发高度。
如图1、图14和图15所示,本实施例中,点燃部4012的径向尺寸小于喷发部4013的径向尺寸,形成由点燃部4012向喷发部4013方向的扩口结构。利用气流变径的突增吸力,可将出口管401内点燃的金属粉末5吸出,使得点燃后的金属粉末5能够被完全喷出冷焰火装置。点燃部4012与喷发部4013之间设有平滑过渡段4015,从而有效防止金属粉末5的结瘤,可以改变气流的流动状况,以使出口管401内的金属粉末5能够完全被吹出。出口管401的进口端4011上设有用于防止出口管401内的热量向风机402方向传递的风机口隔热垫圈404,和/或出口管401的喷口4014上设有用于防止出口管401内的热量向外传递的出口隔热垫圈405。可选地,平滑过渡段4015可以替换为突变过渡段。
如图1、图14和图15所示,本实施例中,防粘层403可以采用喷涂于出口管401内壁面的喷涂层,也可以采用粘附于出口管401内壁面的粘贴层;另外,防粘层403采用聚四氟乙烯层或者特氟龙层。
根据上述结构,冷焰火喷发设备下料时,采用丝杆结构(旋转下料机构103)取代推杆结构、利用下料驱动电机1033和送料驱动电机b的均匀转速、利用下料漏斗102的下料缓冲作用以及控制下料管1031与下料丝杆(下料辊轴1032)之间的间隙,可使金属粉末5能够均匀、连续和平稳的滑入送料丝杆(旋转送料辊203)上,进而解决了冷焰火下料不稳定和不连续的问题。
由于下料丝杆(下料辊轴1032)的丝杆结构,通过调节下料丝杆(下料辊轴1032)和装料料斗101底部的间隙,可使装料料斗101内的金属粉末5能够完全的下料至送料装置2中,进而解决了金属粉末5下料时剩余量的问题。
由于下料装置1的结构特性,可使金属粉末5能够均匀的、平稳的和连续的由下料漏斗102滑落至送料丝杆(旋转送料辊203)上,利用送料丝杆(旋转送料辊203)的丝杆结构和送料驱动电机b的均匀转速,通过控制送料丝杆(旋转送料辊203)和送料管(送料通道201)之间 的间隙以及控制送料丝杆(旋转送料辊203)旋转的转速,可控制送料丝杆(旋转送料辊203)上金属粉末5的均匀性、平稳性和连续性,进而解决了冷焰火装置喷发时火焰不稳和不连续的问题。
冷焰火装置的下料装置1采用减速电机和丝杆结构取代电磁铁和推杆结构下料,可消除电磁铁吸合推杆时产生噪声,极大程度上减小了冷焰火下料时产生的噪声。冷焰火装置采用链轮链条结构传动,不仅能在恶劣的环境中正常工作,而且极大程度上减小了噪声的产生。
下料装置1下料的金属粉末5通过下料漏斗102均匀、连续的分散在送料丝杆(旋转送料辊203)表面和螺纹槽内,增加了金属粉末5与加热机构3的接触面积,而且加热圈301的保温套管302的保温作用,可使送料丝杆(旋转送料辊203)上加热区域内的温度恒定,因此确保了金属粉末5得到充分点燃。
采用加热圈301的保温套管302和丝杆的隔热垫圈303可使加热圈301加热的热量密封在其腔体内,不仅确保送料丝杆(旋转送料辊203)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。
点燃后的金属粉末5到达出口管401时,遇冷会产生金属粉末5熄灭的现象,影响火焰的状态及美观。因此,冷焰火装置的出口管401两端设置了风机口隔热垫圈404和出口隔热垫圈405,而风机口隔热垫圈404和出口隔热垫圈405采用耐热绝缘材料,可杜绝热量传递其他区域起到隔热作用,同时也能使出口管401内部温度恒定,避免点燃的金属粉末5遇冷熄灭。
点燃后的金属粉末5容易粘附在金属表面上,造成出口管401的易结流区域和其他区域产生金属粉末5的结瘤现象,影响出口管401气流的顺利喷出和火焰的美观等性能。因此,冷焰火装置的出口管401内侧采用喷有喷涂层结构,喷涂层采用具有不粘性、抗湿性、耐腐蚀性、耐磨损性以及摩擦系数小等特点的防粘材料,如特氟龙、聚四氟乙烯等。出口管401通过喷涂防粘材料,可有效防止点燃后的金属粉末5粘附在 其易结流区域和其他区域,形成结瘤现象。
由于金属粉末5有一定的重量,点燃后的金属粉末5不能全部被吹出出口管401,少量点燃的金属粉末5会落入风机402内,影响装置的使用性能。该冷焰火装置的出口管401在送料丝杆(旋转送料辊203)附近采用变径结构,利用气流变径的突增吸力,可将送料管(送料通道201)内点燃的金属粉末5能被吸出,使点燃后的金属粉末5被完全吹出该冷焰火装置。
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。
