Description

一种潜水式涡轮增氧机
技术领域
本发明涉及水产养殖装置领域，特别是涉及一种潜水式涡轮增氧机。
背景技术
鱼苗的循环水养殖过程中会产生大量的有害有机物和无机物，并且造成水体酸碱不平衡，影响水质。因此，在鱼苗循环水养殖过程中，需要对循环水进行处理，以使得循环水能满足鱼苗生长的需要。
常见的循环水养殖装置通常利用沙砾、海绵、活性炭等的过滤或吸附作用来去除水体中的悬浮颗粒污染物质，但这些并不能去除一些影响鱼苗健康的有害物质，为了达到健康用水的目的，通常需要定期换水或投喂水质改良剂等化学药品来改良循环水水质，由此，通常会使得鱼苗养殖成本本增，同时又会增加养殖对象的生存风险。
通过水中增氧的方式也是水处理的一种常规手段，现在用于水产养殖的增氧装置通常为叶轮增氧机、水车式增氧机、通过增氧气泵增氧或者微纳米气泡增氧发生器增氧。
叶轮增氧机和水车式增氧机主要通过将水推入空气中，以及搅拌水等作用来增加水与空气的接触面积，达到增氧的效果。但由于水比空气重得多，需要很大的动力才能驱动上述装置，加上动力系统的一系列的传动装置，将电机的动力传递至叶轮过程中能量的消耗，且搅拌入水中的气泡也很大。导致上述装置造成很大耗能的同时，且效率低下，增加了装置生产和维护的成本。
上述增氧装置大多需要通过浮体把机体浮在水面上才能工作，这也增加了设备成本和安装成本。
且气体与水接触的时间短，气泡与水接触的面积也小，溶入水中的氧气含量较小。即使通过微孔或者纳米级的暴气板产生微气泡，但大大增加的出气的阻力，出气的总量也会大大减小，溶入水中的氧气总量也不大，而且微气暴气板的价格不菲，且使用过程中容易被堵塞，维护困难。
发明内容
本发明的目的在于提供一种结构简单且能有效提高增氧效率的潜水式涡轮增氧机。
本发明所采取的技术方案是：
一种潜水式涡轮增氧机，包括叶轮组件和连接在叶轮组件下方的潜水电机，叶轮组件包括叶轮壳体和设置叶轮壳体内与潜水电机的输出端轴连接的叶轮主体，叶轮组件的顶部连接有进气管，进气管的顶部伸出水面，叶轮壳体的外周设有若干排汽口。
进一步作为本发明技术方案的改进，叶轮组件还包括设置在叶轮壳体下方与叶轮主体固定连接的叶轮座，叶轮主体呈倒锥形竖直设置，叶轮主体包括环绕叶轮座彼此间隔竖直设置的若干叶轮片。
进一步作为本发明技术方案的改进，环绕叶轮壳体的外周设有若干等弧度间隔设置的格栅片，两相邻的格栅片间隔形成排汽口。
进一步作为本发明技术方案的改进，各叶轮片的外侧设有倾斜向下的斜边。
进一步作为本发明技术方案的改进，叶轮壳体的内腔为圆柱形。
进一步作为本发明技术方案的改进，叶轮壳体的顶部与进气管的底部间水密性密封。
进一步作为本发明技术方案的改进，潜水电机的底部接触至水底。
本发明的有益效果：此潜水式涡轮增氧机通过将潜水电机伸入水底进行装置的固定，潜水电机带动叶轮组件中的叶轮主体旋转，将顶部空气通过进气管带入叶轮主体，并与叶轮壳体内的水混合形成水气混合物经排汽口排出进行水体增氧，叶轮组件旋转排出水气混合物的过程中，叶轮壳体内形成负压，持续从进气管抽入气体，可维持装置的持续运行，此装置结构简单，通过将气注入水体进行增氧，可减少增氧过程中的能耗，从而有效提高增氧效率。
附图说明
下面结合附图对本发明作进一步说明：
图1是本发明实施例整体结构示意图；
图2是本发明实施例叶轮组件整体结构示意图；
图3是本发明实施例叶轮组件内部结构剖视图。
具体实施方式
参照图1～图3，本发明为一种潜水式涡轮增氧机，包括叶轮组件1和连接在叶轮组件1下方的潜水电机2，叶轮组件1包括叶轮壳体11和设置叶轮壳体11内与潜水电机2的输出端轴连接的叶轮主体12，叶轮组件1的顶部连接有进气管3，进气管3的顶部伸出水面，叶轮壳体11的外周设有若干排汽口。
此潜水式涡轮增氧机通过将潜水电机2伸入水底进行装置的固定，潜水电机2带动叶轮组件1中的叶轮主体12旋转，将顶部空气通过进气管3带入叶轮主体12，并与叶轮壳体11内的水混合形成水气混合物经排汽口排出进行水体增氧，叶轮组件1旋转排出水气混合物的过程中，叶轮壳体11内形成负压，持续从进气管3抽入气体，可维持装置的持续运行，此装置结构简单，通过将气注入水体进行增氧，可减少增氧过程中的能耗，从而有效提高增氧效率。
作为本发明优选的实施方式，叶轮组件1还包括设置在叶轮壳体11下方与叶轮主体12固定连接的叶轮座14，叶轮主体12呈倒锥形竖直设置，叶轮主体12包括环绕叶轮座14彼此间隔竖直设置的若干叶轮片13。
作为本发明优选的实施方式，环绕叶轮壳体11的外周设有若干等弧度间隔设置的格栅片15，两相邻的格栅片15间隔形成排汽口。
作为本发明优选的实施方式，各叶轮片13的外侧设有倾斜向下的斜边。
作为本发明优选的实施方式，叶轮壳体11的内腔为圆柱形。
作为本发明优选的实施方式，叶轮壳体11的顶部与进气管3的底部间水密性密封。
作为本发明优选的实施方式，潜水电机2的底部接触至水底。
此增氧机通过叶轮组件1形成涡轮，叶轮组件1内的叶轮主体12在潜水电机2的带动下转动时，在离心力的作用下，各叶轮片13内的水气混合物被甩出，并经过叶轮壳体11四周的排汽口不断排出，从而会在圆柱形内腔的叶轮壳体11内产生负压，不断通过进气管3把空气吸入叶轮组件1的叶轮片13内，并推入水中。
在离心力的作用下，高速旋转的叶轮片13能将空气切割分散形成极小的微气泡，使气泡在水中的停留时间更长，从而大大提高氧气的传递效率。
由于气泡是被360度水平推力推入水中的，气泡被推入水中后，扩散的范围大，提高了氧气的传递效率。
此涡轮式增氧机颠覆了传统的增氧装置将水推入空气的工艺，而采用将空气推入水中的机械构造，由于空气比水的质量轻很多，很小的动力就能将大量的空气推入水中。加上叶轮组件1高速旋转切割分散气泡，极大地提高了增氧效率。
本增氧机采用潜水电机2，把潜水电机2与叶轮组件1直接连起来，减小了扭矩和电机负荷，从而，能通过更小功率的电机达到更大的氧传递效率。
且潜水电机2的增氧机结构不需要浮体，可节省装置的制作成本，同时节省安装劳动力。
当然，本发明创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
