Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a water treatment flotation device. Background Art

[0002] Water treatment refers to the process of processing raw water for domestic and industrial use, including various methods such as physical treatment, chemical treatment and biological treatment. Flotation devices generate tiny bubbles by introducing air or oxygen into the water. These bubbles adhere to suspended particles in the water to form a three-phase mixed system of water, air and particles. Due to the buoyancy of the bubbles, the density of the suspended particles adhered to the bubbles decreases, causing them to float to the water surface, forming a scum layer, which is then separated and removed. This method is very effective in removing pollutants such as suspended matter, oil, colloids, etc. in the water, and can significantly improve the clarity of the water quality. Flotation devices are suitable for various types of water treatment scenarios, including industrial wastewater treatment, municipal sewage treatment, drinking water pretreatment, etc.

[0003] During the use of existing water treatment flotation devices, since the wastewater to be treated itself contains a certain amount of large particle impurities and suspended matter, if it is directly put into the water treatment flotation device without pre-filtration treatment, these impurities and suspended matter will directly enter the flotation tank, affecting the effective adhesion of bubbles and pollutants, thereby reducing the flotation effect. In addition, large particle impurities and suspended matter will also be directly deposited on the bottom of the flotation tank, increasing the cleaning and maintenance burden of the equipment. At the same time, if the solid separation is completed by relying solely on the bubbles formed by the mixture of dissolved air and water to attract impurities, the overall separation process will be long, seriously affecting the flotation effect, increasing the burden and energy consumption of the equipment, and reducing the water quality of the effluent.

[0004] Therefore, it is necessary to invent a water treatment flotation device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a water treatment flotation device, which accelerates the adsorption speed and effect of dissolved air bubbles on impurities and floating objects through a pre-treatment box, a water inlet pipe, an air flotation room, an air flotation pipe, a jet aerator, a movable rod and a stirring blade, can promote the oxidation and decomposition process of organic matter, and improve the purification effect of water quality, thereby improving the solid-liquid separation efficiency and purification effect of the water treatment flotation device, achieving the effects of enhancing the mixing effect, improving the flotation efficiency, providing power support, optimizing the water flow distribution, increasing the oxygen solubility, reducing the energy consumption, etc., so as to solve the problem that the water treatment flotation device in the prior art is used too much. During the process, since the wastewater to be treated itself contains a certain amount of large particle impurities and suspended matter, if it is directly put into the water treatment flotation device without pre-filtration treatment, these impurities and suspended matter will directly enter the flotation tank, affecting the effective adhesion of bubbles and pollutants, thereby reducing the flotation effect. In addition, large particle impurities and suspended matter will also be directly deposited on the bottom of the flotation tank, increasing the cleaning and maintenance burden of the equipment. At the same time, if the solid separation is completed by relying solely on the bubbles formed by the mixture of dissolved air and water to attract impurities, the overall separation process will be long, seriously affecting the flotation effect, increasing the burden on the equipment and energy consumption, and reducing the water quality of the effluent.

[0006] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a water treatment flotation device, comprising a main flotation tank, which is used to carry wastewater for water flotation treatment;

[0007] The pre-treatment box is arranged on one side of the main flotation tank and is used for pre-filtering the wastewater. A fixing bolt is passed through the outside of the pre-treatment box. One end of the fixing bolt is movably connected to a filter screen. A water inlet pipe is provided above the filter screen.

[0008] A partition plate is provided inside the main flotation tank to divide the internal space of the main flotation tank, and a flocculation room is provided on one side of the partition plate, and an air flotation room is provided on the other side of the partition plate. A dissolved air pump is provided outside the air flotation room, and an air flotation pipe is fixedly installed on one end of the dissolved air pump. A downstream plate is provided on one side of the air flotation room;

[0009] The jet aerator is arranged inside the main flotation tank to accelerate the flotation effect. A movable rod is provided inside the main flotation tank, and a stirring blade is fixedly installed on the outside of the movable rod. A froth box is fixedly installed on the other side of the main flotation tank.

[0010] Preferably, the filter screen is threadedly connected to the pre-treatment box, and the water inlet pipe is fixedly connected to the pre-treatment box.

[0011] Preferably, a fixed plate is fixedly installed above the flocculation room, a servo motor is provided above the fixed plate, a transmission rod is fixedly installed at the output end of the servo motor, and a mixing and stirring disk is fixedly installed on the outside of the transmission rod.

[0012] Preferably, a medicine box is provided on one side of the servo motor, and an electromagnetic control valve is fixedly installed on the outside of the medicine box.

[0013] Preferably, a pressurized water pump is provided outside the main flotation tank, and a water pumping pipe is fixedly installed at one end of the pressurized water pump.

[0014] Preferably, an electric slide rail is provided above the main flotation tank, the outside of the electric slide rail is movably connected to an electric sleeve, one end of the electric sleeve is fixedly mounted with a connecting plate, and the outside of the connecting plate is fixedly mounted with a foam scraper.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model is provided with a pre-treatment box, a water inlet pipe, an air flotation room, an air flotation pipe, a jet aerator, a movable rod and a stirring blade. When the water treatment air flotation device is used, the wastewater first enters the pre-treatment box through the water inlet pipe before entering the water treatment air flotation device. Since a filter is provided inside the pre-treatment box, large particles of impurities and suspended solids in the wastewater can be isolated and filtered for preliminary treatment, which can reduce the processing burden of the water treatment air flotation device and also improve the treatment effect. Then, the wastewater after preliminary filtration enters the flocculation room and flows into the air flotation room. The dissolved air output by the air flotation pipe mixes with water to form bubbles and begins to flot the water. Flotation treatment is carried out. During the flotation process, movable rods and stirring blades are set inside the main flotation tank. The movable rods and stirring blades stir the wastewater and dissolved air bubbles. Then, multiple jet aerators inhale air and mix it with the water flow to form an aerated water flow. This accelerates the adsorption speed and effect of the dissolved air bubbles themselves on impurities and floating objects, which can promote the oxidation and decomposition process of organic matter and improve the water purification effect. This coordinated use also improves the solid-liquid separation efficiency and purification effect of the water treatment flotation device, achieving the goals of enhancing mixing effect, improving flotation efficiency, providing power support, optimizing water flow distribution, increasing oxygen solubility, and reducing energy consumption.

[0017] 2. The utility model is provided with a main flotation tank, a flocculation room, a fixed plate, a servo motor, a transmission rod, a mixing and stirring disk, a medicine box and an electromagnetic control valve. When the water treatment flotation device is used, wastewater enters the main flotation tank by simply opening the pipeline of the medicine box through the electromagnetic control valve, allowing an appropriate amount of chemical agents to enter the flocculation room and be stirred by the rotation of the transmission rod and the mixing and stirring disk. This can change the surface charge of the suspended particles in the water, reduce the repulsive force between the particles, and enable the particles to approach each other and connect into larger flocs through physical or chemical effects. These larger flocs are more easily adsorbed by the bubbles generated during the flotation process, thereby improving the flotation efficiency. This not only improves the removal rate of suspended matter, but also reduces the burden of subsequent treatment steps. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-5 A water treatment flotation device shown includes a main flotation tank 1, which is used to carry wastewater for water flotation treatment;

[0028] The pre-treatment box 2 is provided on one side of the main flotation tank 1 and is used for pre-filtering the wastewater. A fixing bolt 3 is passed through the outside of the pre-treatment box 2. One end of the fixing bolt 3 is movably connected to a filter screen 4. A water inlet pipe 5 is provided above the filter screen 4.

[0029] A partition plate 6 is provided inside the main flotation tank 1 to divide the internal space of the main flotation tank 1. A flocculation chamber 7 is provided on one side of the partition plate 6, and a flotation chamber 14 is provided on the other side of the partition plate 6. A dissolved air pump 17 is provided outside the flotation chamber 14. A flotation pipe 18 is fixedly installed at one end of the dissolved air pump 17. A downstream plate 19 is provided on one side of the flotation chamber 14.

[0030] The jet aerator 20 is arranged inside the main flotation tank 1 to accelerate the flotation effect. A movable rod 21 is provided inside the main flotation tank 1, and a stirring blade 22 is fixedly installed on the outside of the movable rod 21. A froth box 27 is fixedly installed on the other side of the main flotation tank 1. During the flotation process, the movable rod 21 and the stirring blade 22 are provided inside the main flotation tank 1. The movable rod 21 and the stirring blade 22 stir the wastewater and dissolved air bubbles. Then, multiple jet aerators 20 inhale air and mix it with the water flow to form an aerated water flow, which accelerates the adsorption speed and effect of the dissolved air bubbles themselves on impurities and floating objects, thereby promoting the oxidation and decomposition process of organic matter and improving the water purification effect.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, the filter screen 4 is threadedly connected to the pre-treatment box 2, and the water inlet pipe 5 is fixedly connected to the pre-treatment box 2. Before the wastewater enters the water treatment flotation device, it first enters the pre-treatment box 2 through the water inlet pipe 5. Since the filter screen 4 is set inside the pre-treatment box 2, the large particles of impurities and suspended matter in the wastewater can be isolated and filtered for preliminary treatment, which can reduce the processing burden of the water treatment flotation device and also improve the treatment effect. A fixed plate 8 is fixedly installed above the flocculation room 7, and a servo motor 9 is set above the fixed plate 8. A transmission rod 10 is fixedly installed on the output end of the servo motor 9, and a mixing and stirring disk 11 is fixedly installed on the outside of the transmission rod 10. The wastewater and chemicals are rotated and stirred by the transmission rod 10 and the mixing and stirring disk 11, which can change the surface charge of the suspended particles in the water, reduce the repulsive force between the particles, and enable the particles to approach each other and connect into larger flocs through physical or chemical effects. These larger flocs are more easily adsorbed by the bubbles generated during the flotation process, thereby improving the flotation efficiency. A medicine box 12 is provided on one side of the servo motor 9, and an electromagnetic control valve 13 is fixedly installed on the outside of the medicine box 12. When the wastewater enters the main flotation tank 1, it only needs to open the pipe of the medicine box 12 through the electromagnetic control valve 13 to allow an appropriate amount of chemicals to enter the flocculation room 7, thereby assisting the subsequent water treatment flotation work.

[0032] like Figure 1 、 Figure 4 and Figure 5As shown, a pressurized water pump 15 is provided on the outside of the main flotation tank 1, and a pumping pipe 16 is fixedly installed at one end of the pressurized water pump 15. The pressurized water pump 15 and the pumping pipe 16 are responsible for extracting the bottom water after flocculation and sending it to the flotation room 14, thereby completing the flotation work. An electric slide rail 23 is provided above the main flotation tank 1, and an electric sleeve 24 is movably connected to the outside of the electric slide rail 23. A connecting plate 25 is fixedly installed at one end of the electric sleeve 24, and a froth scraper 26 is fixedly installed on the outside of the connecting plate 25. The froth scraper 26 moves back and forth driven by the electric slide rail 23 to scrape the impurities and floating objects after flotation into the froth box 27.

[0033] The working principle of this utility model is as follows: first, the external power supply is turned on, and the water inlet pipe 5 is connected to the external wastewater pipe. In this way, the wastewater does not directly enter the water treatment flotation device before treatment, but enters the pre-treatment box 2 through the water inlet pipe 5. Since the filter screen 4 is set inside the pre-treatment box 2, the large particles of impurities and suspended solids in the wastewater can be isolated and filtered for preliminary treatment, which can reduce the processing burden of the water treatment flotation device and also improve the treatment effect. Then, the wastewater after preliminary filtration passes through the internal pipe of the pre-treatment box 2 and then enters the flocculation room 7. At this time, the pipe of the medicine box 12 can be opened by the electromagnetic control valve 13 to allow an appropriate amount of chemicals to pass through. The medicine enters the flocculation room 7, and then the switch of the servo motor 9 is turned on to drive the transmission rod 10 and the mixing and stirring disk 11 to rotate. In this way, the wastewater and the medicine are subjected to the rotation and stirring of the transmission rod 10 and the mixing and stirring disk 11, which can change the surface charge of the suspended particles in the water, reduce the repulsive force between the particles, and enable the particles to approach each other and connect into larger flocs through physical or chemical effects. These larger flocs are more easily adsorbed by the bubbles generated during the flotation process, thereby improving the flotation efficiency. This not only improves the removal rate of suspended matter, but also reduces the burden of subsequent treatment steps. Then the switch of the pressure water pump 15 is turned on, and the pressure water pump 15 and the pumping pipe 16 extract The secondary treated water under the floccules is sent to the flotation room 14, so that the switch of the dissolved air pump 17 can be turned on, and the dissolved air pump 17 is allowed to inject dissolved air into the flotation room 14 through the flotation pipe 18. The dissolved air output by the flotation pipe 18 mixes with water to form bubbles and begins to flotate the water. Subsequently, during the flotation process, a movable rod 21 and a stirring blade 22 are set inside the main flotation tank 1. The movable rod 21 and the stirring blade 22 stir the wastewater and dissolved air bubbles, and then cooperate with multiple jet aerators 20 to inhale air and mix it with the water flow to form an aerated water flow, which accelerates the adsorption speed and effect of the dissolved air bubbles themselves on impurities and floating objects, and can promote the oxidative decomposition of organic matter. The process improves the water purification effect, and then turns on the switches of the electric slide 23 and the electric sleeve 24, allowing the foam scraper 26 to move back and forth under the drive of the electric slide 23 to scrape the impurities and floating objects after flotation into the foam box 27. In this way, the water treated in the main flotation tank 1 can be discharged from the external water pipe for use. Finally, after completing the installation and use of all water treatment flotation devices according to the above operations, turn off the switch of the servo motor 9, turn off the switch of the pressurized water pump 15, turn off the switch of the dissolved air pump 17, turn off the switch of the electric slide 23, and cut off the external power supply if it is not used for a long time. In this way, the use process of the water treatment flotation device is completed.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
