Description

Technical Field

[0001] The present invention relates to the technical field of dissolved air flotation machines, and specifically to a vortex dissolved air flotation machine based on turbulent flow enhancement. Background Art

[0002] A vortex dissolved air flotation machine based on turbulent flow enhancement is a device that uses the turbulent effect to improve the flotation efficiency and is mainly used in the field of water treatment.

[0003] During the use of existing vortex dissolved air flotation machines, it is difficult to make the particles and bubbles in the fluid mix and collide more fully, resulting in poor flotation effects. At the same time, it is difficult to change the flow direction and velocity distribution of the fluid, which is not conducive to the flotation flow pattern in the flotation machine and reduces the intensity and stability of the vortex. When using a perforated plate in the prior art, it is difficult to control the mixing degree of gas and sewage, resulting in the gas being difficult to be evenly dispersed in the sewage, reducing the flotation efficiency. At the same time, it is difficult to adapt to different concentrations of suspended solids and pollutants, and it is difficult to adjust the pore size according to needs to adapt to different treatment requirements, which may cause impurities to accumulate at the holes and increase the possibility of blockage. When using a perforated plate in the prior art, it is difficult to increase the contact time between the sewage and microbubbles, resulting in a low capture probability of microbubbles. At the same time, it is difficult to reduce the hydraulic resistance, which increases the wear and corrosion of the equipment to a certain extent and shortens the service life of the equipment. Finally: When using existing vortex dissolved air flotation machines, it is difficult to form strong vortices and turbulences, resulting in uneven distribution of bubbles in the sewage, prone to problems such as bubble aggregation and uneven floating, and at the same time reducing the collision probability between bubbles and suspended solids. When using existing vortex dissolved air flotation machines, it is difficult to break the stratification phenomenon between the medicament and the sewage, reducing the efficiency and effect of flotation treatment, and it is difficult to increase the contact area and contact time between the medicament and the sewage, resulting in the medicament being difficult to fully react with the pollutants in the sewage and reducing the coagulation or flocculation effect.

The first mounting box 21 is convenient for installing and fixing the cylinder 22.

[0025] The right end of the fixed rod 23 is fixedly connected with a rotating plate 24. Five groups of adjusting mechanisms 25 are equidistantly arranged at the front end of the rotating plate 24. The pushing rod at the right end of the air cylinder 22 is fixedly connected with a first transmission member 26. The right end of the first transmission member 26 is fixedly connected with a swinging block 27. The swinging block 27 is intermittently matched with the first convex rod 28, and the swinging block 27 is in contact with the first convex rod 28.

[0026] There are eight first convex rods 28, and the eight first convex rods 28 are equidistantly arranged at the right end of the first turntable 29. The left end of the first turntable 29 is fixedly connected with a winding roller 210. A pull rope 211 is wound around the outer wall of the winding roller 210. The bottom of the pull rope 211 is detachably connected with a counterweight 212. The counterweight 212 facilitates driving the pull rope 211 to move.

[0027] The left end of the winding roller 210 is fixedly connected with a torsion spring 213. There are three rotating plates 24, and the three rotating plates 24 are distributed from top to bottom. At the top left and right ends of the lower two rotating plates 24, mounting mechanisms 214 are fixedly connected. The right end of the first turntable 29 is fixedly connected with a fixed rod 23.

And the right end of the gear inside the first transmission member 26 is fixedly connected with a swinging block 27 through a gear rod.

[0029] The working principle of an eddy dissolution air flotation machine based on turbulent flow intensification according to Embodiment 1 is as follows: First, when using this equipment, first place this equipment in the working area, and then connect the device to an external power supply to provide the power required for the operation of this equipment. Second, the external sewage is transported into the eddy current dissolved air flotation machine 1 through the spraying mechanism 4. Then, according to the properties and treatment requirements of the sewage, the staff adds an appropriate amount of coagulant or flocculant through the feeding mechanism 48 to help the suspended substances form larger flocs. Then the external sewage enters the flotation tank. In the flotation tank, due to the sudden decrease in pressure, a large amount of air dissolved in the water precipitates in the form of tiny bubbles. These tiny bubbles collide and adhere to the suspended substances and floc particles in the sewage during the rising process, forming a flotation body with a specific gravity less than that of water, thus realizing the separation of the suspended substances from the water. The scum formed on the surface of the flotation tank is periodically scraped off by the slag scraper in the eddy current dissolved air flotation machine 1. Then, the clear water after air flotation separation is discharged through the water outlet pipe of the flotation tank, completing the operation of the eddy current dissolved air flotation machine. During the use of the eddy current dissolved air flotation machine 1, through the special impeller design at its bottom, when the impeller rotates, it will suck in air while sucking in sewage and form a strong eddy current. This eddy current can fully mix and dissolve the air with the sewage, increasing the solubility of air in the water, thus realizing an efficient air dissolution process; Third, when turbulence intensification is required, start the motor in the first transmission member 26. The motor in the first transmission member 26 drives the gear section in the first transmission member 26 to rotate. The gear section in the first transmission member 26 drives the gear in the first transmission member 26 to rotate. The gear in the first transmission member 26 drives the swing block 27 to swing through the gear rod at its right end. During the use of the motor in the first transmission member 26, after the gear section in the first transmission member 26 and the gear in the first transmission member 26 cooperate once, the motor in the first transmission member 26 rotates in the reverse direction, causing the swing block 27 to swing back and forth. During the back-and-forth swing of the swing block 27, the pull rope 211 moves downward under the influence of the gravity of the counterweight 212. The pull rope 211 drives the winding roller 210 to rotate. The winding roller 210 drives the first turntable 29 to rotate. The first turntable 29 drives the fixed rod 23 to rotate. The fixed rod 23 drives the rotating plate 24 to rotate, realizing the adjustment of the rotation angle of the rotating plate 24, thereby adjusting the angle of the hole 251, making the particles and bubbles in the fluid mix and collide more fully, improving the air flotation effect, and at the same time changing the flow direction and velocity distribution of the fluid, generating more vortices and turbulence, strengthening the turbulence, and forming a flow pattern more conducive to air flotation in the eddy current dissolved air flotation machine 1, enhancing the intensity and stability of the eddy current. During the back-and-forth swing of the swing block 27, through the contact with the first convex rod 28 and the gravity factor of the counterweight 212, the rotation angle of the first turntable 29 is fixed; Fourth, during the rotation of the winding roller 210 and the first turntable 29, the torsion spring 213 undergoes a torsional movement. When it is necessary to restore the winding roller 210 and the first turntable 29, the air cylinder 22 is started. The air cylinder 22 drives the first transmission member 26 to move to the right. The first transmission member 26 drives the swing block 27 to move to the right, so that the swing block 27 is in a non-contact state with the first convex rod 28. Then the staff removes the counterweight 212. The torsion spring 213 is restored and drives the winding roller 210 to be restored. The winding roller 210 drives the first turntable 29 to be restored.

[0030] Embodiment 2:

Compared with Embodiment 1, this embodiment further includes: an adjustment mechanism 25. The adjustment mechanism 25 includes holes 251.

[0033] A polytetrafluoroethylene coating 255 is electrolessly plated inside the stainless steel wire mesh 254. A silane coating 256 is sprayed inside the polytetrafluoroethylene coating 255.

[0034] In this embodiment: First, due to the good elasticity and plasticity of the fluororubber 253, the staff can select fluororubbers 253 with different thicknesses. Then, due to the high strength and corrosion resistance of the stainless steel wire mesh 254, the fluororubber 253 is supported and fixed. Furthermore, due to the excellent corrosion resistance and low friction coefficient of the polytetrafluoroethylene coating 255, it prevents the sewage from corroding and polluting the holes 251. Then, due to the good adhesion and corrosion resistance of the silane coating 256, the corrosion resistance and anti-pollution ability of the holes 251 are further improved. Then, the fluororubber 253, the stainless steel wire mesh 254, the polytetrafluoroethylene coating 255, and the silane coating 256 are adhesively connected to the inner side of the holes 251 in sequence by the UV degradation glue 252 to complete the installation of the multi-layer material layer. By selecting fluororubbers 253 with different thicknesses, the staff can effectively change the size of the holes 251, control the mixing degree of the gas and the sewage, make the gas evenly dispersed in the sewage, improve the air flotation efficiency, and at the same time adapt to different concentrations of suspended solids and pollutants, meet different treatment requirements, and reduce the possibility of blockage. When it is necessary to replace the thickness of the fluororubber 253, it is irradiated with an external UV lamp to make it lose its viscosity, realizing lossless disassembly and replacement.

Compared with Embodiment One, this embodiment further includes: a feeding mechanism 48. The feeding mechanism 48 includes a third installation box 481. The right end of the bottom of the second turntable 45 is fixedly connected with the third installation box 481. The bottom of the third installation box 481 is fixedly connected with a first motor 482. The third installation box 481 is convenient for installing and fixing the first motor 482.

[0051] The top output shaft of the first motor 482 is fixedly connected with a single gear 483. The front end of the single gear 483 is intermittently matched with a grooved wheel 484. The top of the grooved wheel 484 is fixedly connected with a third turntable 485 through a wheel rod.

[0054] In this embodiment: When it is necessary to transport coagulants or flocculants into the eddy current dissolved air flotation machine 1, the second motor 415 on the right side of the Y-shaped rotating block 43 is started. The second motor 415 drives the fourth turntable 414 to rotate, so that the two groups of nozzles 4811 move above the eddy current dissolved air flotation machine 1.

By changing the size of the holes 251, the mixing degree of gas and sewage is controlled, enabling the gas to be evenly dispersed in the sewage, improving the air flotation efficiency, and at the same time adapting to different suspended solids and pollutant concentrations, adapting to different treatment requirements, and reducing the possibility of blockage; provided with an installation mechanism 214. By installing and splicing the two groups of rotating plates 24, the contact time between the sewage and the microbubbles is increased, the capture probability of the microbubbles is improved, the hydraulic resistance is reduced, and to a certain extent, the wear and corrosion of the equipment are reduced, and the service life of the equipment is prolonged; provided with a spraying mechanism 4. By spraying the external sewage into the eddy current dissolved air flotation machine 1 through the spraying nozzles 47, strong vortices and turbulent flows are formed, making the distribution of bubbles in the sewage relatively uniform, reducing the problems of bubble aggregation and uneven floating, and increasing the collision probability between the bubbles and the suspended solids; provided with a feeding mechanism 48. By moving the two groups of nozzles 4811, the coagulants or flocculants are transported into the eddy current dissolved air flotation machine 1, breaking the layering phenomenon between the coagulants or flocculants and the sewage, improving the efficiency and effect of air flotation treatment, and at the same time increasing the contact area and contact time between the coagulants or flocculants and the sewage, enabling them to fully react with the pollutants in the sewage and improving the coagulation or flocculation effect.
