[0002] In the field of wastewater treatment technology, air flotation, as a highly efficient solid-liquid separation method, is widely used in industrial wastewater, municipal sewage, and drinking water treatment. Its core principle is to release microbubbles into the water, causing them to adhere to the surface of pollutant particles, forming an air-floc complex with a density less than water. This allows for the separation and removal of pollutants through buoyancy.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 and Figure 2This utility model provides an embodiment of an integrated multi-stage high-speed air flotation device, including a reaction tank 1, used as a wastewater treatment site, made of stainless steel or concrete. A flocculation tank 2 is fixedly connected to the inner wall of the reaction tank 1. The upper part of the flocculation tank 2 is configured as a continuous groove shape. A baffle plate 3 is fixedly connected to the upper part of the reaction tank 1 near the flocculation tank 2. The baffle plate 3 is located directly above the center of the groove, and three sets are arranged. The two sets of baffle plates 3 on the left are at the same height, while the set of baffle plates 3 on the right is lower than the two sets on the left. The air flotation process proceeds through the flocculation tank 2... In conjunction with baffle plate 3, hydraulic flocculation is performed, and the flocculation time is controlled within 5 to 7 minutes. A baffle plate b11 is fixedly connected to the left side of the flocculation tank 2. The height of baffle plate b11 is lower than that of baffle plate 3, so that the mixed wastewater can flow into the flocculation area through baffle plate b11. A baffle plate c7 is fixedly connected to the right side of the flocculation tank 2. The height of baffle plate c7 is lower than that of the set of baffle plates 3 on the right side, and the upper part is inclined. In conjunction with the set of baffle plates 3 on the right side, the wastewater is guided, so that the impurities flocculated by the wastewater can fully adsorb air bubbles when the wastewater passes through the flotation pipe 6.
[0032] Furthermore, a partition plate 8 is fixedly connected to the middle of the right side of the reaction tank 1. The height of the partition plate 8 is lower than that of the first set of baffle plates 3 on the right side but higher than that of the baffle plate c7. By cooperating with mechanical or hydraulic sewage discharge, the scum is cleaned into the L-shaped trough on the right side of the partition plate 8, and the sludge is sucked out by the water pump 10 and the sewage pipe. The upper part of the reaction tank 1 is equipped with a water pump 10, which is a sewage pump. Two sets of water pumps are provided. One set is used to discharge scum and impurities, and the other set is connected to the air flotation pipe 6 through a pipe to transport 8% to 10% return pressurized water. A partition a9 is fixedly connected to the bottom right side near the partition plate 8. The height of partition a9 is lower than that of partition plate 8, which discharges the cleaned sewage. A conveying pipe 4 is fixedly connected to the left side of the reaction tank 1 for discharging sewage containing mixed agents. The outlet end of the conveying pipe 4 is close to the bottom of the reaction tank 1. An auxiliary component 5 is set between the inner wall of the left side of the reaction tank 1 and the partition b11. An air flotation pipe 6 is set on the left side of the partition c7, which is connected to a dissolved air system such as a dissolved air tank and a release device to transport saturated dissolved air water to the air flotation zone. At the same time, it can transport dissolved air and 8% to 10% return pressurized water.
[0033] Reference Figures 1-3The auxiliary component 5 includes an outer frame 51 movably connected between the reaction tank 1 and the baffle b11, used to support multiple sets of baffles. These baffles are installed using galvanized bolts for easy disassembly and maintenance. A base plate is fixedly connected to the lower part of the outer frame 51 to improve its stability. A baffle a52 is fixedly connected to the upper surface of the outer frame 51 near the base plate. The front and rear sides of baffle a52 are away from the inner wall of the reaction tank 1, guiding the water flow to diffuse to both sides, forming turbulence, promoting rapid mixing of the chemical solution input from the delivery pipe 4 with the wastewater, shortening the mixing time to 1-2 minutes. A baffle b53 is fixedly connected to the upper surface of the outer frame 51 near baffle a52. The middle part of baffle b53 is hollow, allowing for... A central flow channel is formed, which generates turbulence again. A baffle c54 is fixedly connected to the surface of the outer frame 51 near the baffle b53. A vertical through hole is opened on the surface of the baffle c54. The diameter of the vertical through hole of the baffle c54 is 5-10mm, which further rectifies the flow and mixes the medicine and sewage transported by the conveying pipe 4. There is no need to use a motor for mechanical stirring, which reduces the cost of use. A fixing plate 55 is fixedly connected to the upper part of the outer frame 51. The fixing plate 55 is inserted into the inner wall of the reaction tank 1 and fixedly installed on the reaction tank 1 by the limiting member 56. The limiting member 56 is fixedly connected to the upper part of the reaction tank 1. The limiting member 56 allows the outer frame 51 to be quickly disassembled, thereby improving maintenance efficiency.
[0034] Reference Figure 1 and Figure 4 The limiting member 56 includes a fixed frame 561 fixedly connected to the upper part of the reaction tank 1, which can limit the limiting rod 563 and prevent the limiting rod 563 from deviating. A limiting groove 562 is opened through the outer side of the fixed frame 561. The limiting groove 562 is L-shaped. The limiting groove 562 cooperates with the operating member 564 to limit the limiting rod 563. The limiting rod 563 is slidably connected to the inner wall of the fixed frame 561. A protrusion is provided on the upper left side of the limiting rod 563 to prevent the limiting rod 563 from detaching from the fixed frame 561. The lower surface of the limiting rod 563 contacts the upper surface of the fixed plate 55 to limit the fixed plate 55 in the vertical direction. The right surface of the limiting rod 563 rotates. An operating member 564 is dynamically connected. The outer side of the operating member 564 is rod-shaped and can slide on the inner wall of the limiting groove 562. The limiting rod 563 is elastically connected to the operating member 564 through a torsion spring 565. The elastic force of the torsion spring 565 makes the rod-shaped part on the operating member 564 initially horizontal. The limiting groove 562 can limit the limiting rod 563 in the horizontal direction. The limiting member 56 also includes a plug-in member 566, which limits the left side of the limiting rod 563 to improve its stability. The plug-in member 566 is fixedly connected to the upper part of the reaction tank 1. The limiting rod 563 is inserted into the inner wall of the plug-in member 566, and the surface of the operating member 564 slides on the inner wall of the limiting groove 562.
[0035] Working principle: During use, the wastewater after mixing with the reagent enters the reaction tank 1 through the left-side conveying pipe 4. The outlet end is close to the bottom of the tank, where the water flow impact force initially disperses the wastewater. Baffle a52 guides the water flow to diffuse to the front and back sides of the reaction tank, forming turbulence and accelerating the initial mixing of the reagent and wastewater. The mixing time is controlled at 1 to 2 minutes. The water flowing through baffle a52 flows upward through baffle b53, where the hollow structure in the middle forms a central guiding channel, creating turbulence again and enhancing the mixing effect. The mixed liquid continues to flow upward through baffle c54, whose surface has vertical through holes with a diameter of 5 to 10 mm to rectify the water flow and further homogenize the mixing state of the reagent and wastewater, preparing for subsequent flocculation.
[0036] The mixed wastewater enters the flocculation tank 2 through the baffle b11. The continuous groove structure at the top of the flocculation tank 2, in conjunction with the baffle plate 3, forms a hydraulic flocculation environment. The flocculation time is controlled at 5 to 7 minutes. The two sets of baffle plates 3 at the same height on the left guide the water flow, prolong the residence time, and promote floc growth. The flocculated wastewater is guided towards the air flotation pipe 6 through the inclined upper part of the baffle c7, which cooperates with the lower baffle plate 3 on the right, in preparation for air flotation separation.
[0037] The air flotation tube 6 connects to the dissolved air system, such as the dissolved air tank and the release device, and delivers 8% to 10% of the reflux pressurized water and saturated dissolved air water. The dissolved air water releases tiny bubbles with a particle size of about 10-30μm, which come into full contact with the flocs formed by flocculation. The bubbles are adsorbed on the surface of the flocs, forming an "air-floc" composite with a density less than that of water.
[0038] In the mixture after air flotation, the "air-floc" complex floats to the water surface to form scum. The separator 8 intercepts the scum in the left area and uses mechanical scraper or hydraulic discharge. The sludge is then sucked out by the water pump 10. The cleaned sewage flows into the right area through the bottom of the separator a9 and is discharged through the pipe to complete the purification. Dissolved air and 8% to 10% return pressurized water are transported through a set of water pumps 10.
[0039] When cleaning or replacing auxiliary component 5 is required, the operating part 564 of the operating limit part 56 is operated: the operating part 564 is initially kept in a horizontal state by the torsion spring 565 and is stuck in the inner wall of the L-shaped limit groove 562, restricting the horizontal movement of the limit rod 563. The operating part 564 is rotated upward to make it slide along the horizontal section of the limit groove 562, which drives the limit rod 563 to slide away from the fixed plate 55, so that the outer frame 51 can be quickly removed and multiple sets of baffles can be removed by bolts, shortening maintenance time.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
