Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in the attached drawings, the vertical spiral-flow type gas-liquid mixer for increasing the foaming amount comprises a circular cyclone 5, wherein the circular cyclone 5 is tightly clamped between a left annular flange plate 3 and a right annular flange plate 3, the left annular flange plate 3 and the right annular flange plate 3 are fixedly connected through a split bolt 2, the two flange plates 3 are coaxial with the circular cyclone 5, a plane is arranged on the circumferential side wall of the cyclone 5, a counter bore is arranged at the position of the plane and consists of an upper unthreaded hole and a lower threaded hole, the lower end of an upper flange 1 is inserted into the unthreaded hole and is in transition fit with the upper flanged flange 1 and the lower flanged flange, a shaft shoulder on the outer wall of the upper flange 1 is pressed on the plane of the circumferential side wall of the cyclone 5, an air inlet channel is arranged in the middle of the upper flange 1, and a stepped air outlet door 4 is arranged in the annular cavity of the cyclone 5, notch cuttype air outlet door 4 the centre have the air inlet with the cavity intercommunication for cavity and top, air outlet door 4's upper portion diameter be less than the lower part, air outlet door 4's upper portion and screw hole threaded connection and fixed through the diapire of nut with the unthreaded hole, air outlet door 4 outer wall on the shaft shoulder press on the inner wall of the annular cavity of swirler 5, prevent that air outlet door 4 from removing. The air inlet of the air outlet door 4 is communicated with the air inlet channel, and a plurality of air outlet holes communicated with the cavity of the air outlet door 4 are uniformly distributed on the side wall and the bottom wall of the lower part of the air outlet door 4. A plurality of flow deflectors are welded on the inner wall of the annular cavity of the swirler 5.
