Embodiment 1

[0032] see Figure 1-5, an advection air flotation device for sewage treatment, including an air flotation tank 1, a throughput device 2, a drive pipe 3 and an oil cylinder 4, the air flotation tank 1 is used for circulating sewage, and the throughput device 2 is used for viscous in the sewage The thick mixture is discretized; the specific structure and connection method of the above structure are as follows, the throughput device 2 is located in the air flotation tank 1 and it includes a horizontal cage 21, a positioning ring 22 and a V-shaped wheel 23, and the positioning ring 22 gap sleeve Located on the outside of the horizontal cage 21, the positioning ring 22 is vertically distributed, and the V-shaped wheel 23 is rotatably connected to the ring body of the positioning ring 22 and is evenly distributed in the circumferential direction. The specific connection structure is that the positioning ring 22 is provided with There is an inclined shaft 222 that rotates with the V...

Embodiment 2

[0034] see figure 1 and Image 6 The further description relative to Embodiment 1 is that the left support ring plate 211 is fixedly installed on the side wall opposite to the side wall where the right support circular plate 213 is located in the air flotation tank 1, and the other two opposite inner side walls and the bottom of the air flotation tank 1 The side is used in conjunction with the brush bar 232, that is to say the air flotation box 1 can be made into a cuboid shape, and the free end of the brush bar 232 covers the lower position and the bottom of the four sides of the air flotation box 1, thus the first embodiment The throughput device 2 can partially clean the inner wall of the air flotation tank 1, avoid sticky matter on it, and improve the corrosion resistance of the air flotation tank 1; the outer diameter of the roller 5 is greater than the outer diameter of the connecting shaft 221, and the roller A sleeve 51 is fixedly connected to the end opposite to the ...

Abstract

The invention discloses a horizontal-flow type air floatation device for sewage treatment. The horizontal-flow type air floatation device comprises an air floatation box, a throughput device, a driving pipe and an oil cylinder, in the present invention, a horizontal cage-shaped cylinder is arranged in the air floatation box; a cylinder body of the horizontal cage-shaped cylinder is a spiral shaftstroke which is uniformly distributed in the circumferential direction; a positioning ring is arranged outside the cylinder body of the horizontal cage-shaped cylinder in a clearance sleeving manner;V-shaped wheels which are uniformly distributed in the circumferential direction are rotationally connected to a ring body of the positioning ring; the V-shaped wheels are in rolling fit with the spiral shaft; brush strips which are uniformly distributed in the circumferential direction are fixedly arranged on the outer peripheries of the V-shaped wheels; when the positioning ring axially moves, the positioning ring rotates; simultaneous autoroatation of positioning rings, the brush strips on the V-shaped wheels uniformly distributed on the V-shaped wheels stir the sewage and roll inwards at the advancing side to scrape the water; sewage containing viscous mixed impurities is scraped into the opening, the viscous mixed impurities are extruded to the center of the positioning ring by the hairbrush strip, and the viscous mixed impurities are discretized under the brushing action of the hairbrush strip, so that the viscous mixed impurities are convenient to contact with microbubbles subsequently and float upwards.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an advection air flotation device for sewage treatment. Background technique [0002] The main principle of the air flotation machine is to expose the micro-bubbles dissolved in high-pressure water into the sewage, so that the micro-bubbles can adsorb the suspended matter in the sewage, and use the floating effect of the air bubbles to make the suspended matter float to the surface of the sewage, and then float to the surface of the sewage. The suspended matter on the surface of the sewage is salvaged, so as to achieve the purification effect of the sewage; [0003] Since the sewage entering the sewage tank of the air flotation machine contains a large amount of irregular mixed viscous debris, such debris in the sewage sticks together, specifically sticky debris and debris with a density greater than water, resulting in air flotation. The treatment is not thor...
