Description

TECHNICAL FIELD

[0001] The application relates to the technical field of air floatation oil removal, in particular to an integrated air floatation oil removal device. BACKGROUND

[0002] Air floatation is a process in which highly dispersed micro-bubbles are formed in water, the hydrophobic solid or liquid particles in sewage are adhered, a three-phase mixed system of water, gas and particles is formed, after the particles adhere to the bubbles, the flocculation with a smaller apparent density than water is formed and floated to the water surface, a dross layer is formed and scraped off, so that the solid-liquid or liquid-liquid separation is realized. At present, the air floatation oil removal technology is widely used in the field of sewage treatment. In the current mechanical manufacturing, a large amount of emulsion is used as lubricating cooling in metal cutting and machining, the emulsion becomes waste water after being used for a period of time, the emulsion contains a large amount of machine oil and a surfactant, the emulsion is prepared by diluting the emulsified oil with water and then adding an emulsifier, and in order to improve the rust resistance of the emulsion, sodium nitrite and other components are added in the emulsion used in the machine tool cutting, so that the waste emulsion has stable properties, complex components, high organic matter concentration and high oil content, and is difficult to treat. Improper treatment will cause serious environmental pollution and has a certain influence on production and life. At present, most factories use the air floatation method to carry out air floatation oil removal on the waste emulsion, but in the current air floatation oil removal device, the generated bubbles are large and sparse, the waste emulsion cannot be effectively treated, and a large amount of oil remains in the treated waste emulsion, so the treatment effect is poor. Therefore, how to more efficiently carry out air floatation oil removal on the waste emulsion.

[0003] A waste emulsion air floatation oil removal device is disclosed in Chinese Patent No. CN211025233U, which comprises a box body, a gas pump is arranged on the right side of the box body, the gas pump runs to fill compressed air into the connecting pipe, the compressed air reaches the horizontal pipe through the connecting pipe and the vertical pipe, and is dispersed to five generating pipes at the top of the horizontal pipe, after the compressed air flows into the generating pipe, the valve plate is opened outward and the spring is stretched under the action of the pressure, at this time, the compressed air flows into the inside of the waste emulsion through the valve port, a large amount of bubbles are generated, the bubbles are floated upward under the action of the buoyancy, and are separated into smaller bubbles by the rotating crushing net, so that the oil dregs in the waste emulsion are more efficiently adsorbed. The utility model has the advantages of simple structure, novel design, solving the problem of large and sparse bubbles generated by the traditional air floatation oil removal device, and being capable of generating highly dispersed micro-bubbles.

[0004] The device can assist in improving the generation of bubbles, but during use, it can only improve the efficiency of bubble generation, lacks an oil stain treatment and filtering mechanism during use, and it is not convenient to quickly treat and filter the oil stains on the top after the bubbles float up. The residual sewage after oil treatment also contains a certain amount of oil stains. Obviously, the above technical solution has certain defects in treating oil stains, and during use, it can only agitate the bubbles at the bottom and cannot be fully agitated. After the bubbles float up, they are easily condensed into large bubbles, affecting the air floatation effect, and there are certain deficiencies during overall use.

[0039] Please refer to Figure 3 The aeration mechanism 9 comprises an air pump 91 fixedly installed on the back of the fixed side plate 10, a communication pipe 92 fixedly installed at the bottom of the air pump 91, an aeration pipe rack 93 fixedly installed at the bottom of the communication pipe 92, aeration exhaust pipes 94 fixedly installed at the top of the aeration pipe rack 93 at equal intervals, and the top of each aeration exhaust pipe 94 is connected in communication with the bottom of the treatment tank 4. The air pump 91 is arranged to run, and the air pump 91 runs to pump air to the aeration pipe rack 93 through the communication pipe 92, and the air is uniformly discharged into the treatment tank 4 through the aeration exhaust pipes 94 at the top of the aeration pipe rack 93, thereby achieving a better sewage treatment bubble formation effect.

[0040] The working principle of this invention is as follows: During the use of this equipment, by setting up the stirring mechanism 5, the aeration mechanism 9, and the driving mechanism 6 in coordination, the equipment can first be started by running the air pump 91. The air pump 91 delivers air to the aeration pipe frame 93 through the connecting pipe 92. Through the aeration pipes 94 evenly spaced at the top of the aeration pipe frame 93, the air bubbles can be evenly discharged into the interior of the treatment tank 4. At this time, by starting the first motor 63, the first motor 63 drives the first transmission pulley 62 to rotate. Through the transmission belt, both sets of first transmission pulleys 62 rotate. Simultaneously, the rotation of the first transmission pulleys 62 can assist in driving the rotation of the second transmission pulley 64. Through the synchronous rotation of the first transmission pulleys 62 and the second transmission pulleys 64, the air bubbles can be evenly discharged into the interior of the treatment tank 4. The first rotating shaft 51 and the second rotating shaft 52 can be driven to rotate. The rotation of the first rotating shaft 51 and the second rotating shaft 52 drives the first dispersing plate 53 and the second dispersing plate 54 to rotate. The rotation of the first dispersing plate 53 and the second dispersing plate 54 helps to disperse the bubbles burst by the aeration mechanism 9 through the dispersing mesh 55. Because the first dispersing plate 53 and the second dispersing plate 54 are triangularly arranged, they can completely tumble and disperse the interior of the treatment tank 4, resulting in high overall dispersing efficiency and continuous, comprehensive dispersing of bubbles. This achieves a good bubble dispersing effect and improves the air flotation capacity. By setting up a suction mechanism 8, the equipment can be operated by starting the suction pump 82 during use, at which time the electromagnetic induction valve at the suction pipe 8105 is closed. The solenoid valve 8104 of valve 8104 is opened, and the suction hose 88 is activated. The suction pump 82 then starts operating. The telescopic cylinder 86 is activated, causing the suction bucket 87 to move downwards. Once the suction bucket 87 moves downwards, it contacts the foam on top of the wastewater in the treatment tank 4. The second motor 89 is activated, driving the lead screw 83 on the inner side of the guide rail 811 to drive the slider 84 to slide. The sliding slider 84 assists in moving the mounting plate 85 laterally, which in turn moves the suction bucket 87 laterally, facilitating the complete suction of the foam. The suction pump 82 then draws wastewater from the foam area inside the treatment tank 4 and discharges the foam through the suction hose 88 and the drain pipe 8103 into the filter mechanism 7. Once the top foam has been treated, the suction hose 88 can be closed. The solenoid valve 8104 is activated, and the solenoid valve 8104 at the suction pipe 8105 is opened. At this time, the suction pump 82 is started, which can draw the treated water and discharge it into the filter mechanism 7. This facilitates the equipment to quickly treat the foam inside the treatment tank 4 and filter the treated wastewater. During filtration, the filtered wastewater can be discharged through the drain pipe 8103. The overall treatment capacity is strong and convenient. By setting up the filter mechanism 7, the filter element 75 can be used to filter foam and wastewater during use. When the filter element 75 is saturated, the handle tube 77 on the connecting rod 76 can be pulled to lift and pull the slide plate 74 to slide inside the slide groove 73. The filter element 75 can be quickly removed by sliding out through the slide plate 74.The metal filter screen 751 can assist in supporting each filter screen, improve the stability of each filter screen, the plastic woven filter screen 755 has a larger pore size, can be suitable for filtering larger particles of oil stains, the glass fiber filter screen 754 can effectively capture oil stain particles and has a high filtering efficiency, the membrane filter screen 753 has a microporous structure, can effectively filter small particles and colloidal substances, the activated carbon filter screen 752 is filled with activated carbon particles, can adsorb organic substances and odor substances in the oil stains, improve the filtering effect, so that the device can have a strong oil filtering function.
