Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
An air flotation oil removing device used in environmental protection engineering comprises an air flotation tank 1, as shown in figure 1, wherein a feeding pipe 7 is arranged on the upper half part of the left side wall of the air flotation tank 1, after liquid is guided into the air flotation tank 1 through the feeding pipe 7 by a pump, because the bottom of the air flotation tank 1 is provided with an annular titanium pipe 2, the annular titanium pipe 2 is connected with an air blower 5 positioned outside the air flotation tank 1 through an air inlet pipe 4, and the side wall of the annular titanium pipe 2 is uniformly provided with an air outlet 3, when in use, the air blower 5 discharges the gas into the air flotation tank 1 through the air inlet pipe 4, the annular titanium pipe 2 and the air outlet 3, wherein the gas discharged through the air outlet 3 uniformly floats upwards from the bottom to form highly dispersed micro bubbles in water, solid or liquid particles of hydrophobic groups in waste water are adhered to form a water-gas-particle three-phase mixed system, after the particles are adhered to the bubbles, flocs with apparent density smaller than that of the water are, forming a scum layer.
Wherein install the frame 13 of fixed motor 14 at air supporting groove 1 top, and motor 13 is connected with the scraper 6 that is located inlet pipe 7 top air supporting groove 1 through axis of rotation 15, wherein scraper 6 is located on the liquid surface, and be fixed with the adsorbed layer that the material is the oil absorption blanket on scraper 6, it is rotatory through motor 14 drive axis of rotation 15 and scraper 6, make the adsorbed layer on scraper 6 clear up the oil on the liquid surface, and inhale oil blanket through the washing and retrieve oil, and the liquid after the deoiling is discharged by the discharging pipe 8 that is located air supporting groove 1 right side wall bottom, discharging pipe 8 is located annular titanium pipe 2 top in this embodiment, make discharging pipe 8 easily discharge the deposit that probably silts up in air supporting groove 1 bottom.
And the top end of the side wall of the air flotation tank 1 is outwards turned with a folded edge 9, wherein a plurality of groups of mounting holes 10 are uniformly arranged on the folded edge 9, screw rods 11 are arranged in the mounting holes 10, nuts 12 positioned at the upper end and the lower end of the folded edge 9 are screwed on the screw rods 11, and the screw rods 11 are prevented from moving up and down in the mounting holes 10 in a locking mode through the upper group of nuts and the lower group of nuts 12, so that the stability of the screw rods in the mounting holes 10 is improved, and the top ends of the screw rods 11 and the bottom ends of the frame 13 are welded and fixed, so that the frame 13 and the motor 14 are suspended.
In the embodiment, the number of the screws 11 is equal to the number of the mounting holes 10, wherein the number of the screws 11 is at least three, since the liquid level in the air flotation tank 1 may change each time when in use, which may cause the scraper 6 not to be located on the liquid surface, so that the adsorption layer on the surface of the scraper 6 may not well scrape off the floating oil on the water surface, whereas in the past, the cylinder is mounted on the top of the air flotation tank 1 to move the frame 13 up and down, so that the scraper 6 is driven by the moving frame 13, the motor 14 and the rotating shaft 15 to move up and down, thereby changing the position where the scraper is located so that the scraper is located on the liquid surface, but since the number of the required cylinders is large and is easy to damage, the production cost is increased, thereby being not suitable for some small enterprises, and in the embodiment, when the scraper 6 needs to be adjusted downward, only the nut 12 above the folding edge 9, drive frame 13, motor 14, axis of rotation 15 and scraper 6 after moving down to the assigned position simultaneously, then upwards rotatory be located hem 9 below nut 12, through upper and lower two sets of nuts 12 with screw rod 11 locking in mounting hole 10 prevent displacement from top to bottom can, and the operating method when needing upwards to adjust scraper 6 is then positive contrary, because the position that adopts mode adjustment scraper 6 of adjusting nut 12 in this embodiment, not only with low costs in comparison with the mode in the past, also be difficult for damaging simultaneously.
