Embodiment 1

[0023] A vertical shaft double-turbine mixer, comprising a parallel gear reduction motor 1, an elastic fixed base 2, a hollow transmission shaft 4, and a turbine stirring impeller 5, the parallel gear reduction motor 1 is installed on the installation base 3 through the elastic fixed base 2, One end of the hollow transmission shaft 4 is connected to the parallel gear reduction motor 1, and the other end is connected to the turbine stirring impeller 5. The turbine stirring impeller 5 is in the shape of a concave cone, and long guide stirring ribs are distributed along the circumference on the inner side of the concave cone arc surface. 6 and short diversion stirring ribs 7; the long diversion stirring ribs 6 and the short diversion stirring ribs 7 are alternately distributed.

[0024] The long diversion stirring ribs 6 are distributed in a spiral involute shape along the concave conical arc surface of the turbine stirring impeller 5, and the intersection points of the extended l...

Abstract

The invention belongs to the technical field of environmental protection facilities, and discloses a vertical shaft-type double-turbine mixer. The vertical shaft-type double-turbine mixer comprises a parallel gear deceleration motor (1), an elastic fixing base (2), a hollow transmission shaft (4) and a turbine stirring impeller (5). The turbine stirring impeller (5) is in a shape of a concave taper. Long diversion stirring ribs (6) and short diversion stirring ribs (7) are arranged on an inner side of an arc surface of the concave taper and along the periphery. The long diversion stirring ribs (6) and short diversion stirring ribs (7) are arranged in intervals. Compared with common stirring equipment, the vertical shaft-type double-turbine mixer has excellent energy-saving advantages, and has power density of 1.5 to 2.0W/m<3>. Compared with a traditional underwater mixer, the vertical shaft-type double-turbine mixer has an energy saving rate of above 50 to 60% and can protect bods against damage.

Description

technical field [0001] The invention belongs to the technical field of environmental protection facilities and relates to a vertical-shaft twin-turbine mixer. Background technique [0002] In the urban sewage treatment process, the stirring of the mixed liquid is the key process. At present, most of the applications are double-blade paddles and multi-blade paddle mixers with the impeller shafts placed horizontally. The structure of these blades is suitable for specific mixing requirements. It plays a certain role, but there are more or less deficiencies, such as: such as the local flow velocity in the mixing area, the sludge mass passing through the impeller is easily broken, there is a certain dead angle of mixing, underwater drive motor, reducer maintenance It is more difficult, and the impeller is easy to hang with impurities. Moreover, the power density of ordinary agitators is as high as 5-8W / m 3 . Contents of the invention [0003] The object of the present invent...
