Description

一种含有多个送风通道的风机 技术领域
本发明涉及一种风机，尤其是一种设置了多个送风道，能够帮助提高抽气效率的多叶离心式风机。
技术背景
随着我国现代化建设进程，我们应用能源的产品越来越多，我们对能源的需求也越来越多，进而节能减排成为现代化建设必不可少的手段。
以保温产品为例，在众多的产品中有很多是应用真空技术生产的，而随着极端气候变化越来越频繁的今天，寒冷和炎热将不可避免的考验着人们，因而性能良好的保温产品成为减少应对在这些天气的最佳选择。不管是建筑、家电或其它方式的节能，要在保证性能良好的前提下又能打规模应用，其成本是关键，而成本的一个重要环节就是生产过程中的能源成本。
真空制品的保温性能是目前保温产品中最好的产品之一，现在没有大量应用真空产品来提高保温效率有一个重要因素是现有真空抽气系统的效率太低，耗费的能源成本太大，使生产真空制品的成本价位无法下降。造成这一问题的关键是真空抽气系统的真空泵或离心式风机的效率太低。
而离心式风机的效率相对较低的关键原因是现有技术离心式风机的叶轮的长度受局限，现有市场的离心式风机的叶轮是以将叶轮的后盘安装在电机轴上，叶轮的叶片和前盘悬空，叶轮的轴向进气空腔只有一个的方式制作的，其导致如果加长叶轮的情况下，在高速旋转过程中其叶片不能以最佳的方式将其上面的动能施加给叶轮中的空气，因而效率低，能耗高。
综上所述，现有技术的离心式风机效率低，能耗高的主要原因是其设计局限。

进一步的，所述隔离通风道内设置有分割管，所述分割管的管道壁通过连接骨架A与所在隔离通风道的隔离管的管道壁连接并将所在隔离通风道分割成两个分割通风道。如果需要，还可以将分割通风道进一步分成更多的通风道。所述分割管帮助隔离管将送风空腔隔离成多个独立的送风通道，在叶轮的叶片滚筒被加长的情况下有助于将进气管道的空气均衡的输送给叶片滚筒的各个部位，以提高叶轮的效率。
进一步的，所述送风单元还包括辅助支架，所述辅助支架包括支撑端和与其连接的辅助套，所述支撑端通过连接骨架B与隔离管或分割管的管道壁连接，所述辅助套与辅助轴承连接，所述辅助轴承的内圈或外圈与叶轮的传动轴连接并与叶轮的轴心保持一致。所述辅助轴承的外圈或内圈在随传动轴转动过程中，其内圈或外圈将对固定的辅助套进行支撑稳定，以在叶轮高速转动过程中增加送风单 元的稳定性。
进一步的，所述叶轮的叶片滚筒上设置有一个或多个增强箍圈，所述增强箍圈与叶片滚筒周边的叶片连接并保持在一个平面上，以在增加叶轮的叶片滚筒长度的情况下增加叶片滚筒的结构强度，来保证加长了的叶片滚筒在高速转动过程中对刚性强度的要求。所述增强箍圈与叶片滚筒周边的叶片连接的平面应尽量与叶轮的轴线垂直，以减少叶片滚筒在转动过程中的阻力，进而减少能耗。
进一步的，所述进气管道的进气端与机壳的结合部位安装有密封圈，所述密封圈具有良好的密封性，以确保机壳不会进入进气管道以外的空气，来提高风机抽取进气管道的效率。
进一步的，所述传动轴穿过机壳与电机的轴连接，所述传动轴和机壳的结合部位安装有具有密封性能的轴承，以在不影响传动轴转动的同时防止机壳以外的空气从该处进入机壳内。
进一步的，所述电机安装在机壳内，并使安装电机的空间与叶轮的空间连通，使传动轴不必穿过机壳，以减少空气从机壳外进入机壳内的可能。

本发明的有益效果：
相对于现有市场的离心式风机，本发明的含有多个送风通道的风机的叶轮长度可以根据用户要求加长，在相同直径和相同转速的情况下，叶轮被加长的风机由于送风空腔被隔离成多个独立的送风通道而更有效的对其叶轮的各个部位均衡的输送空气，因而可以最大化的发挥叶轮被加长的优势，在转动过程中通过更多的作用点将送风空腔内的空气更有效的径向抛送，进而通过出气口向外排放。即——在既定的排气量和叶轮直径相同的情况下，加长的叶轮可以通过对电机减速的办法来达到节能的目的；在电机功率和转速以及叶轮直径相同的情况下，加长的叶轮能够排出更多的排气量，进而提高了本发明的含有多个送风通道的风机的效率。连接在叶轮的前盘上的从动圈安装在从动轴承上，而从动轴承安装在进 气管道的管道壁的外壁上，使从动装置在不影响进气管道进气空间的情况下，确保加长的叶轮不会在高速转动过程中失去稳定性，叶轮耗费较少的能量能够提高风机更高的效率，并为设计者提供设计基础。在叶片滚筒的上设置的增强箍圈将相邻的叶片之间的连接起来，增加了叶片缸筒的结构强度，强化了叶轮的抗变形强度，防止了加长的叶轮会在高速转动过程中因离心力变形的可能。在分割管的管道壁与传动轴之间设置的辅助支架进一步的确保了送风单元的稳定性，使送风单元具备一定抗震性能，为其在移动过程中工作提供可靠的保障。本发明的含有多个送风通道的风机节能明显，稳定性好，有保证的提高了离心式风机的效率，其结构简单，易于生产，应用市场广泛。

本发明的一种含有多个送风通道的风机，包括风机本体1，所述风机本体1包括叶轮6，和向叶轮6提供动力的电机11，和用于约束空气的机壳7，以及用于向叶轮1输送空气的进气管道，和设置在机壳7上的出气口71；所述叶轮6包括传动轴60、前盘63和后盘61，以及安装在前盘63和后盘61之间的叶片滚筒62，和由前盘63、后盘61和叶片滚筒62三者之间形成的圆柱形的送气空腔50，所述后盘61安装在传动轴60上并随其转动，所述叶片滚筒62由多个叶片组成；所述进气管道包括进气端3和送风单元5，所述进气端3通过固定件4安装在叶轮6的送气空腔50的进气口并与框架2和机壳7连接，所述送风单元5设置在送气空腔50内，所述送风单元5包括隔离管51，所述隔离管51的管道壁的一端通过支撑骨架52与进气管道的进气端3的管道壁连接，所述隔离管51将送风空腔50隔离成两个隔离通风道53；所述传动轴60与电机11的轴通过联轴器连接；所述出气口71设置在叶轮6的径向方向的机壳7上；所述机壳7安 装在框架2上。所述隔离管51将送风空腔50隔离成两个独立的送风通道53，在叶轮6的叶片滚筒62被加长的情况下有助于将进气管道的空气均衡的输送给叶片滚筒62的各个部位，以提高风机本体1的效率。为确保电机11与叶轮直径的连接稳定性，传动轴上安装有轴承，所述轴承通过轴承位12固定在固定支架上，所述固定支架与框架2连接。所述机壳除出气口71和进气管道外，其它部位具有良好的密封性。
作为上述技术方案的改进，所述风机本体1还包括从动装置，所述从动装置包括与叶轮6的前盘63连接的从动圈81，和安装在进气管道的进气端3在机壳7内的一端的从动轴承8，所述从动圈81与从动轴承8连接并与叶轮6的轴心保持一致。所述从动装置用于在增加叶轮的叶片滚筒62长度的情况下帮助叶轮6的后盘61保持叶轮6在高速转动的过程中的稳定性。
作为上述技术方案的改进，所述隔离通风道53内设置有分割管54，所述分割管的管道壁54通过连接骨架55与所在隔离通风道53的隔离管51的管道壁连接并将所在隔离通风道63分割成两个分割通风道56。如果需要，还可以将分割通风道56进一步分成更多的通风道。所述分割管54帮助隔离管51将送风空腔50隔离成多个独立的送风通道，在叶轮6的叶片滚筒62被加长的情况下有助于将进气管道的空气进一步的均衡的输送给叶片滚筒62的各个部位，以提高风机本体1的效率。
作为上述技术方案的改进，所述送风单元5还包括辅助支架58，所述辅助支架58包括支撑端65和与其连接的辅助套66，所述支撑端65通过连接骨架57与隔离管51或分割管54的管道壁连接，所述辅助套66与辅助轴承64连接，所述辅助轴承64的内圈或外圈与叶轮6的传动轴60连接并与叶轮6的轴心保持一致。所述辅助轴承64的外圈或内圈在随传动轴转动过程中，其内圈或外圈将对固定的辅助套66进行支撑稳定，以在叶轮6高速转动过程中增加送风单元5的稳定性。
作为上述技术方案的改进，所述叶轮6的叶片滚筒62上设置有一个或多个增强箍圈68(未出示)，所述增强箍圈68与叶片滚筒62周边的叶片连接并保持在一个平面上，以在增加叶片滚筒62长度的情况下增加叶片滚筒62的结构强度，来保证加长了的叶片滚筒62在高速转动过程中对刚性强度的要求。所述增强箍 圈68与叶片滚筒62周边的叶片连接的平面应尽量与叶轮6的轴线垂直，以减少叶轮6在转动过程中的阻力，进而减少能耗。
作为上述技术方案的改进，所述进气管道的进气端3与机壳7的结合部位安装有密封圈9，所述密封圈9具有良好的密封性，以确保机壳7不会进入进气管道以外的空气，来提高风机本体抽取进气管道的效率。
作为上述技术方案的改进，传动轴60穿过机壳7与电机11的轴连接，所述传动轴60和机壳7的结合部位安装有具有密封性能的轴承，以在不影响传动轴60转动的同时防止机壳7以外的空气从该处进入机壳7内。
作为上述技术方案的改进，所述电机11安装在机壳7内，并使安装电机11的空间与叶轮6的空间连通，使传动轴60不必穿过机壳7，以减少空气从机壳7外进入机壳7内的可能。
作为上述技术方案的改进，所述隔离管51为圆柱形管道，以更均匀的将进气管道的空气输送给叶片滚筒62的各个部位。
作为上述技术方案的改进，所述分割管54为圆柱形管道，以更均匀的将进气管道的空气输送给叶片滚，62的各个部位。
上述叶轮被加长指的是在现有风机的叶轮的基础上增加长度。
当本发明的含有多个送风通道的风机应用在真空抽气系统时，将进气管道的进气端3与抽气腔室连接，将风机本体1的出气口71与排气管道连接并在排气管道设置反回流装置，所述反回流装置用于防止外部的空气从该装置部位向机壳内流动。
需要抽气时，启动电机11，与电机11的轴连接的传动轴60在随电机转动过程中带动叶轮6的后盘61转动，后盘61将带动叶片滚筒62转动，在转动过程中，与进气管道的进气端3的管道壁连接的送风单元5将会把进气管道内的空气均匀的输送到叶片滚筒62从前盘63到后盘61之间的各个部位，进而使叶片滚筒62的叶片最大化的应用电机11传递给它们的动能，叶片滚筒62的叶片将所在位置的空气径向向周边抛送，这时机壳7内叶轮以外的位置的空气压力将增大，进而从反回流装置处向出气管道的另一端排气。
在叶轮6随电机11高速转动的过程中，从动装置的从动轴承8将在损耗很小的能耗的情况下确保与其连接的从动圈81的稳定性，进而增加了与从动圈81 连接的叶轮6在高速转动过程中的抗震性能。
在叶轮6随电机11高速转动的过程中，与送风单元5的分割管54的管道壁连接的辅助支架58的辅助套66在辅助轴承64的作用基础上，在不影响叶轮6转动的情况下，确保了送风单元在风机本体工作过程中的抗震性能。
本发明的风机本体在设置了从动装置和辅助支架后，为含有多个独立送风通道的叶轮的进气空腔提供了可靠的支撑基础，进而使本发明的含有多个送风通道的风机的实际应用提供了保证。
进一步的，本发明的含有多个独立送风道的风机还可以用于向地铁站，矿洞或其它需要强力通风设施的地方。
本发明的含有多个送风通道的风机效率高，抗震性强，结构简单，实用性强，并能够规模化生产。
最后需要说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换，而不脱离本发明技术方案的主题范围，其均应涵盖在本发明的权利要求范围当中。
