An air pump is composed of motor, drive shaft, impeller, pump, inside and outside the cavity, a frame, water inlet part, a motor arranged on the machine frame, inside and outside the cylinder is arranged between the frame and the cavity plate, the transmission shaft is installed inside the pump, the coupling and motor shaft connected with the tail end of the transmission shaft between the impeller. The impeller is arranged in the cavity and the cavity cover, outer cylinder is provided with air inlets and air inlet adjusting ring, a hole cavity cover, which is characterized in that the bottom of the cavity with a group of water inlet hole, a water outlet of the water outlet side group, against the direction of rotation of the motor, the impeller blade along the spiral direction of the tilt angle is 30 - 45 degrees outside the cavity circle and the water hole corresponding to a set of baffle, baffle is located in the middle of the two adjacent holes, the hole axis angle and vertical plane of beta is equal to 2 An upper water inlet pipe is arranged between the cavity guard plate and the outer air cylinder, and the upper water inlet pipe hole is kept at h between 150-400 millimeters from the axial distance of the water inlet of the cavity body.
【技术实现步骤摘要】
本技术涉及一种污水净化设备，具体地说是一种气浮泵。本技术是这样实现的该气浮泵由电机、传动轴、内外气筒、腔体、叶轮、机架、上进水管几部分组成，电机装在机架上，在机架与腔体盖板之间装有内外气筒，传动轴装在内气筒内，用联轴器与电机轴伸连接，传动轴末端装有叶轮，叶轮置于腔体与腔体盖板之间，外气筒上有进气孔，并装有进气调节环，腔体盖板上有出气孔，腔体底部有一组进水孔，侧面有一组出水孔，其出水孔逆着电机旋转方向，亦即顺着叶轮叶片螺旋方向倾斜，其倾角α为30-45°角，腔体外园周上与出水孔对应地设置一组挡板。挡板位于相邻两孔中间，其角度与孔轴线垂直平面成β等于20-40°夹角；在腔体护板与外气筒之间还装有上进水管，该上进水管孔距腔体进水孔之轴向距离h，根据不同的功率可在150-400毫米范围内选取。采用本技术因消能措施得当，设计参数合理，其同等功率下，比现有的气浮设备产气泡量大，气泡细碎均匀，气浮效果强。权利要求1.一种气浮泵，由电机、传动轴、内外气筒、腔体、叶轮、机架、上进水管几部分组成，电机装在机架上，在机架与腔体盖板之间装有内外气筒，传动轴装在内气筒内，用联轴器与电机轴伸连接，传动轴末端装有叶轮，叶轮置于腔体与腔体盖板之间，外气筒上有进气孔，并装有进气调节环，腔体盖板上有出气孔，其特征在于腔体底部有一组进水孔，侧面有一组出水孔，其出水孔逆着电机旋转方向，亦即顺着叶轮叶片螺旋方向倾斜，其倾角α为30-45°角，腔体外园周上与出水孔对应地设置一组挡板，挡板位于相邻两孔中间，其角度与孔轴线重直平面成β等于20-40°夹角；在腔体护板与外气筒之间还装有上进水管，该上...
