Description
一、技术领域1. Technical field
本实用新型涉及工业、生活废水处理使用的曝气机，尤其是单叶中置推流式低噪节能曝气机。The utility model relates to an aerator used for industrial and domestic waste water treatment, in particular to a push-flow type low-noise energy-saving aerator with a single leaf in the middle.
二、背景技术2. Background technology
为了加速工业、生活废水处理，常采用曝气机。目前一般采用罗茨风机、输气管道、曝气头组成的曝气机，存在着投资大、维护检修不便，运行费用高等不足之处。在2001年5月，由化学工业出版社公开出版的实用水处理设备手册，公开了“一种端置复叶推流曝气机”，存在着制作复叶叶轮加工难度大，维护检修不便，轴承油封易损等不足。In order to speed up the treatment of industrial and domestic wastewater, aerators are often used. At present, the aerator composed of Roots blower, gas pipeline and aeration head is generally used, which has the disadvantages of large investment, inconvenient maintenance and repair, and high operating cost. In May 2001, the Handbook of Practical Water Treatment Equipment published by the Chemical Industry Press disclosed "a plug-flow aerator with end-mounted compound leaves". The bearing oil seal is fragile and so on.
三、发明内容3. Contents of the invention
本实用新型的目的是提供一种结构简单，制作维护方便，提高空气流速和压强的单叶中置推流式低噪节能曝气机。The purpose of the utility model is to provide a simple structure, easy manufacture and maintenance, and improve the air velocity and pressure.
本实用新型的目的所采用的技术方案是，包括有带有小孔的电机座上端固定电机、下端固定有导气管，电机输出轴连接有主轴，其特征是主轴中上段外圆装配有呈螺旋片的螺旋送风增压器、中下段外圆有呈锥形的外壁有螺旋槽的螺旋加速器、下端装有单叶叶轮，导气管下端连接有孔的下端面带气液分离环的上法兰盘的上端有孔的叶轮壳体，螺旋加速器下端面装在上法兰盘上，带有轴承和油封的主轴穿过螺旋加速器和上法兰盘的中心孔，叶轮壳体下端装配有导轮的导轮外壳，导轮外壳的下端装配有混液直管，混液直管的下端装配有上小下大的扩压管，扩压管的下端装配有导向分配器总成。The technical solution adopted by the purpose of this utility model is that the upper end of the motor seat with a small hole is used to fix the motor, the lower end is fixed with an air duct, and the output shaft of the motor is connected to the main shaft. Spiral air supply supercharger, spiral accelerator with tapered outer wall and spiral groove in the outer circle of the middle and lower section, single-blade impeller at the lower end, and upper method with gas-liquid separation ring on the lower end surface connected with holes at the lower end of the air guide pipe The upper end of the blue plate has a hole in the impeller housing, the lower end of the helical accelerator is mounted on the upper flange, the main shaft with bearings and oil seals passes through the center hole of the helical accelerator and the upper flange, and the lower end of the impeller housing is equipped with a guide The guide wheel housing of the wheel, the lower end of the guide wheel housing is equipped with a mixed liquid straight pipe, the lower end of the mixed liquid straight pipe is equipped with a diffuser tube with a small upper part and a larger lower part, and the lower end of the diffuser tube is equipped with a guide distributor assembly.
本实用新型，螺旋加速器的外壁螺旋槽的壁与轴心线的夹角α为30°-60°。In the utility model, the included angle α between the wall of the spiral groove on the outer wall of the helical accelerator and the axis line is 30°-60°.
本实用新型其工作原理，电机通过主轴带动机体(导气管)内的螺旋送风增压器高速旋转，通过高速旋转螺旋送风增压器，使进入的空气流速和压强得到增强。气流再经螺旋加速器导向锥作用向下加速旋转流动，以一定的速度旋转向下进入由气液分离环形成的气室，旋转气流与搅拌推流叶轮旋转方向形成较小的进气夹角，减小进气气流阻力。同时搅拌推流单叶叶轮高速旋转，在叶背和叶前中心尾流区产生较强负压，空气经消音小孔进入，通过导气管、螺旋送风增压器和螺旋加速器被直接吸入。在气液分离环的作用下水只能直接进入叶背，有效避免叶轮背端负压区水和气混合，冲击碰撞，产生喘振噪音。在叶轮的作用下，水和气在叶轮室及导轮室内混合、并被强烈分割搅拌，混合液在叶轮的推力作用下进入混流区，重新被压力水渗透乳化，由导轮、混液直管、扩压管等组成的混液区较长、水和气混合渗透乳化充分。通过导向分配器总成形成高速水柱，定向辐射到水池的纵深服务面上，乳化后的空气，因失压迅速分离成微小气泡，从而提高了氧的转移率，达到了充氧净化污水的目的。The working principle of the utility model is that the motor drives the spiral air supply supercharger in the body (air duct) to rotate at high speed through the main shaft, and through the high-speed rotating spiral air supply supercharger, the flow rate and pressure of the incoming air are enhanced. The air flow is then accelerated downward by the guide cone of the helical accelerator, and rotates downward at a certain speed into the air chamber formed by the gas-liquid separation ring. Reduce intake airflow resistance. At the same time, the single-blade impeller rotates at a high speed, generating a strong negative pressure in the wake area of the back and front center of the blade. The air enters through the small sound-absorbing hole, and is directly inhaled through the air guide pipe, the helical air supply supercharger and the helical accelerator. Under the action of the gas-liquid separation ring, the water can only directly enter the back of the blade, effectively avoiding the mixing of water and gas in the negative pressure area at the back end of the impeller, impacting and colliding, and generating surge noise. Under the action of the impeller, water and air are mixed in the impeller chamber and the guide wheel chamber, and are strongly divided and stirred. The mixed liquid zone composed of diffuser tubes and other components is relatively long, and water and gas are mixed, permeated and emulsified fully. The high-speed water column is formed by the guide distributor assembly, which radiates directionally to the deep service surface of the pool. The emulsified air is quickly separated into tiny bubbles due to pressure loss, thereby improving the transfer rate of oxygen and achieving the purpose of oxygenating and purifying sewage. .
此外，射出的水，造成池底水域服务面紊流，失压后上冒气泡的动能传递给水介质，形成上下水层与曝气机进水口进水的环流，由于叶轮中置曝气机的进水口到导向分配器出水口距离增大，进水的环流半径大，使得搅拌更加均匀、充分，从面获得了更高的动力效率。In addition, the ejected water causes turbulent flow on the service surface of the water area at the bottom of the pool. After the pressure is lost, the kinetic energy of the upward bubbles is transferred to the water medium, forming a circulation between the upper and lower water layers and the water inlet of the aerator. The distance from the water inlet to the water outlet of the guide distributor is increased, and the circulation radius of the water inlet is large, which makes the mixing more uniform and sufficient, and obtains higher power efficiency from the surface.
本实用新型，具有结构简单紧凑，制作、装配、维修方便，机电一体化，操作简单，成本低，维护费用少，低噪、高效、节能等特点。The utility model has the characteristics of simple and compact structure, convenient manufacture, assembly and maintenance, mechatronics, simple operation, low cost, low maintenance cost, low noise, high efficiency and energy saving.
