Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, and in particular to an integrated electrolytic flocculation dissolved air flotation wastewater treatment machine. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater through specific technologies to meet the standards for discharge into natural water bodies or reuse. This technology has been deeply integrated into various sectors of modern society: in the construction industry, it is used to treat domestic sewage and construction wastewater; in agriculture, it can purify irrigation runoff and livestock and poultry breeding wastewater; in the transportation industry, it can treat wastewater from highway service areas and port terminals; and in the energy and petrochemical industries, it is used for the specialized treatment of industrial production wastewater.

[0003] Chinese patent CN213231856U discloses an integrated electrolytic flocculation dissolved air flotation wastewater treatment machine, including a housing. A DC power supply is fixedly installed on the inner wall of the housing, and the output end of the DC power supply is movably connected to a cathode and an anode. An electrolytic separation zone is fixedly installed on the inner bottom wall of the housing. Since the electrolytic flocculation wastewater treatment device and the flotation device are integrated into one unit, the equipment can be integrated into one unit, improving the automation level and working efficiency of the device. At the same time, it consumes the dissolved gas generated when the wastewater is decomposed, reducing the gas pressure inside the device, thereby reducing the probability of dangerous accidents such as explosions.

[0004] Although the device reduces the internal air pressure, thereby lowering the probability of dangerous accidents such as explosions, its integration is not centralized enough, resulting in an excessively large size. Furthermore, the rigid linkage between the scraper and the sprocket makes it prone to jamming due to fibrous impurities. Utility Model Content

[0005] The purpose of this invention is to solve the problems of excessive size and easy jamming of a single slag removal method in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] An integrated electrolytic flocculation dissolved air flotation wastewater treatment machine includes a housing. A wastewater tank is inserted into the bottom left side of the housing's outer surface. A metal door is installed on the right side of the front section of the housing's outer surface. An observation port is opened in the middle of the outer surface of the metal door. An installation plate is fixedly installed inside the wastewater tank. A second connecting pipe is fixedly installed on the front section of the installation plate's outer surface, and a groove is opened on the axial surface of the second connecting pipe near the center of the wastewater tank. A first connecting pipe is inserted into the front section of the axial surface of the second connecting pipe, and a groove is opened at the top of the axial surface of the first connecting pipe. A handle is installed through the outer surface of the first connecting pipe and at the top of the first connecting pipe. A meter is fixedly installed inside the wastewater tank at the rear end of the installation plate. A return spring is installed on the front section of the installation plate's outer surface, and a connecting pipe is installed on the front section of the return spring's outer surface. A water pipe is fixedly installed at the top of the wastewater tank's outer surface, and a water pump is inserted into the middle of the axial surface of the water pipe. A lower partition is installed at the top of the wastewater tank inside the housing, and an upper partition is installed on the upper surface of the lower partition inside the housing near the top.

[0008] Furthermore, an AI edge computing box is installed on the top of the upper partition of the outer shell, a DC power supply is installed on the rear end of the outer surface of the AI ​​edge computing box, a power cord is installed at the output end of the DC power supply, and a mounting bracket is inserted into the axial surface of the power cord near the bottom.

[0009] Furthermore, brackets are installed on both sides of the bottom of the outer surface of the mounting bracket, and the bottom of the outer surface of the brackets is installed on the upper partition. The bottom of the shaft surface of the power cord penetrates the outer surface of the upper partition and is installed with a swirling air-dissolving chamber. The shaft surface of the swirling air-dissolving chamber is installed on the right side of the lower partition inside the housing, and the top of the shaft surface of the water pipe extends through the outer surface of the water pipe to the interior of the swirling air-dissolving chamber.

[0010] Furthermore, a honeycomb electrode is installed at the bottom end of the shaft surface of the power cord, an electrode contamination sensor is electrically installed at the top of the outer surface of the honeycomb electrode, and a multispectral water quality sensor is installed at the bottom of the inner side of the swirling dissolved air chamber.

[0011] Furthermore, a liquid level sensor is electrically installed in the middle of the interior of the swirling gas dissolving chamber, an ultrasonic amplitude sensor is electrically installed in the bottom of the interior of the swirling gas dissolving chamber, several sets of ultrasonic transducers are installed in the bottom of the interior of the swirling gas dissolving chamber, a protective box is installed in the middle of the bottom of the axial surface of the swirling gas dissolving chamber, and a PEMFC micro fuel cell is installed inside the protective box, and the PEMFC micro fuel cell is connected to the ultrasonic transducers through a connecting wire.

[0012] Furthermore, a rotating shaft is installed at the top of the outer surface of the motor, and two sets of scrapers are inserted into the shaft surface of the rotating shaft.

[0013] Furthermore, a Venturi pneumatic reflux device is installed on the front side of the bottom end of the axial surface of the swirling dissolved air chamber, a microporous titanium tube aeration membrane is installed at the connection between the swirling dissolved air chamber and the Venturi pneumatic reflux device, and a clear water tank is installed at the output end of the Venturi pneumatic reflux device.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the modular integrated design significantly improves the compactness of the equipment: the AI ​​edge computing box, high-frequency pulse DC power supply and vortex dissolved air chamber are integrated into an upper and lower layered structure, and the electrical area and treatment area are separated by the upper partition. At the same time, the integrated stamping process with the sewage tank and vortex dissolved air chamber sharing the same side wall is adopted, which greatly reduces the size of the equipment compared with the traditional electrolysis-air flotation split device. The Venturi pneumatic reflux device is integrated with the bottom of the dissolved air chamber and is self-driven by a pressure difference of 0.3-0.6MPa, replacing the traditional electric reflux pump, further reducing the size of the equipment and effectively solving the problem of excessive equipment size in the prior art.

[0016] 2. In this utility model, a polyurethane flexible chain replaces the rigid sprocket drive. Combined with a serrated silicone scraper and an integrated ultrasonic vibrating plate, when treating wastewater containing fibers, the flexible chain can shake off entangled impurities through three short flips. The ultrasonic vibrator destroys the fiber adsorption force through high-frequency vibration, greatly reducing the scraper jamming failure rate. The capacitive contamination sensor on the top of the honeycomb electrode group is linked with the DC power supply pulse backflush function. When the detected scale is >1mm, it automatically triggers a +15V / 10s→-3V / 2s cleaning program. Combined with the anti-entanglement design of the ultrasonic vibrating plate, the equipment can adapt to wastewater with a fiber content ≤500mg / L, expanding the applicable range compared to traditional rigid transmission devices, thus solving the equipment failure problem caused by fiber entanglement.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-4 As shown, this utility model provides an integrated electrolytic flocculation dissolved air flotation wastewater treatment machine, including a shell 1. The machine is characterized by: a wastewater tank 4 inserted into the bottom left side of the outer surface of the shell 1; a metal door 2 installed on the right side of the front section of the outer surface of the shell 1; an observation port 3 opened in the middle of the outer surface of the metal door 2; an installation plate 8 fixedly installed inside the wastewater tank 4; a second connecting pipe 7 fixedly installed on the front section of the outer surface of the installation plate 8; a slot opened on the axial surface of the second connecting pipe 7 near the center of the wastewater tank 4; a first connecting pipe 6 inserted into the front section of the axial surface of the second connecting pipe 7; and the top of the axial surface of the first connecting pipe 6... The end is provided with a slot. The top of the outer surface of the first connecting pipe 6 penetrates the outer surface of the sewage tank 4 and is equipped with a handle 5. The meter 9 is fixedly installed inside the sewage tank 4 at the rear end of the mounting plate 8. The front of the outer surface of the mounting plate 8 is equipped with a return spring 10, and the front of the outer surface of the return spring 10 is equipped with a connecting pipe 6. The top of the outer surface of the sewage tank 4 is fixedly installed with a water pipe 11. A water pump 12 is inserted into the middle of the shaft surface of the water pipe 11. The middle of the inner side of the outer shell 1 is equipped with a lower partition 32 at the top of the sewage tank 4, and an upper partition is installed inside the outer shell 1 near the top of the lower partition 32.

[0026] The overall effect of Embodiment 1 is as follows: the outer shell 1 is welded from 304 stainless steel, and an installation plate 8 is installed inside as a support platform for the core component. The front section of the installation plate is fixed with a second connecting pipe 7, and its axial surface is grooved and connected to the first connecting pipe 6 by an O-ring seal. The top of the first connecting pipe 6 extends into a sewage tank 4 and is equipped with an engineering plastic handle 5 for easy disassembly and maintenance. A high-precision meter 9, model KEF-DN50, is installed at the rear of the sewage tank to monitor the influent flow rate in real time. A specially designed reset spring 10 is linked with the first connecting pipe 6 to buffer the impact of water pressure fluctuations. The top water pipe 11 is connected to a centrifugal water pump 12 through a clamp to lift sewage to the treatment area. The outer shell is equipped with a double-layer partition structure: the lower partition 32 supports the weight of the equipment, and the upper partition separates the electrical and treatment areas. The metal door is equipped with a tempered glass observation port 3 for visual inspection of the liquid level. Pulling the handle 5 moves the first connecting pipe 6 to pour in sewage. After completion, releasing the handle 5 causes the reset spring 10 to move the first connecting pipe 6 back to its original position.

[0027] Example 2, as Figures 3-4 As shown, an AI edge computing box 19 is installed on the top of the upper partition of the outer shell 1. A DC power supply 18 is installed on the rear end of the outer surface of the AI ​​edge computing box 19. A power cord 13 is installed at the output end of the DC power supply 18. A mounting bracket 21 is inserted into the axial surface of the power cord 13 near the bottom. Brackets 22 are installed on both sides of the bottom end of the outer surface of the mounting bracket 21. The bottom end of the outer surface of the bracket 22 is installed on the upper partition. A swirling dissolved air chamber 23 is installed through the outer surface of the upper partition. The axial surface of the swirling dissolved air chamber 23 is installed on the right side of the lower partition 32 inside the outer shell 1. The top end of the axial surface of the water pipe 11 extends through the outer surface of the water pipe 11 to the inside of the swirling dissolved air chamber 23.

[0028] The overall effect of Embodiment 2 is as follows: an AI edge computing box 19 (equipped with an NVIDIA Jetson Xavier NX module) is installed on the top of the upper partition, communicating with various sensors via the Modbus RTU protocol. A high-frequency pulse DC power supply 18 (model PSP-2010, output 0-50V / 200A, with ±5V pulse backflush function) is connected to its rear. The power cord 13 passes through a waterproof connector into the processing area. The mounting bracket 21 is fixed to the upper partition via side supports 22, forming a suspension structure. The end of the power cord is connected to the vortex dissolved air chamber 23, and a water pipe 11 is connected to the upper part of the vortex dissolved air chamber 23, utilizing the kinetic energy of the incoming water to generate vortex flow (flow velocity ≥2m / s), eliminating the need for a traditional stirring motor.

[0029] Example 3, as Figures 4-5As shown, a honeycomb electrode 15 is installed at the bottom of the shaft surface of the power cord 13. An electrode contamination sensor 14 is electrically installed at the top of the outer surface of the honeycomb electrode 15. A multispectral water quality sensor 16 is installed at the bottom of the swirling dissolved air chamber 23. A liquid level sensor 20 is electrically installed at the middle of the inside of the swirling dissolved air chamber 23. An ultrasonic amplitude sensor 29 is electrically installed at the bottom of the inside of the swirling dissolved air chamber 23. Several sets of ultrasonic transducers 24 are installed at the bottom of the swirling dissolved air chamber 23. A protective box 25 is installed at the middle of the bottom of the shaft surface of the swirling dissolved air chamber 23. A PEMFC micro fuel cell is installed inside the protective box 25. The PEMFC micro fuel cell is connected to the ultrasonic transducers 24 through a connecting wire. A rotating shaft 27 is installed at the top of the outer surface of the motor 26. Two sets of scrapers 28 are inserted into the shaft surface of the rotating shaft 27.

[0030] The overall effect of embodiment 3 is as follows: the bottom end of the power cord 13 is connected to the honeycomb electrode assembly 15, which is composed of a hexagonal array of multiple titanium-based IrO2-Ta2O5 coated electrode sheets. The top of the honeycomb electrode 15 integrates an electrode fouling sensor 14 (model CPS-200, measurement range 0-5mm, accuracy ±0.1mm) to monitor the scale thickness in real time. The bottom of the vortex chamber is equipped with: a multispectral water quality sensor 16 (model YSIEXO2, monitoring COD / ammonia nitrogen / turbidity / TDS) and an ultrasonic transducer 24 (model UP-400A, 40kHz). The power is adjustable from 50 to 400W. It is powered by a PEMFC micro fuel cell (model H-500, output 200W) inside the protective box 25. The magnetostrictive liquid level sensor 20 (model MTS-R series, range 0-1.5m, ±1mm error) and the piezoelectric ultrasonic amplitude sensor 29 (model VIB-6, range 5-50μm) are installed on the side wall. The geared motor 26 (model RV-30, 0.75kW) drives the rotating shaft 27, which drives two sets of polytetrafluoroethylene scrapers 28 to remove sludge. The scraper spacing is adjustable (10-50mm).

[0031] Example 4, as Figure 5 As shown, a Venturi pneumatic reflux device 31 is installed on the front side of the bottom end of the swirl dissolved air chamber 23. A microporous titanium tube aeration membrane 30 is installed at the connection between the swirl dissolved air chamber 23 and the Venturi pneumatic reflux device 31. A clear water tank 17 is installed at the output end of the Venturi pneumatic reflux device 31.

[0032] The effect achieved by the entire embodiment 4 is that the microporous titanium tube aeration membrane 30 (pore diameter 0.1mm, made of Japanese Fuji Special Metal) is used as a dissolved air release device, and the bubble particle size CV value is ≤5%; the Venturi pneumatic reflux device 31 is self-driven by the pressure difference of the vortex chamber 0.3-0.6MPa, which does not require electricity and is more energy-efficient than the traditional reflux pump. The outlet end is connected to the PE material clean water tank 17. When the liquid level sensor 20 detects that the water level reaches 1m, it notifies the personnel to open the metal door 2 to extract the clean water. The whole system is realized by the AI ​​edge computing box 19: the electrolysis parameters are dynamically adjusted according to the data of the water quality sensor 16, and the ultrasonic power is controlled by the feedback of the amplitude sensor 29. When the pollution degree sensor (14) detects that the scale is >1mm, it triggers the DC power supply 18 pulse backflush +15V / 10s→-3V / 2s self-cleaning electrode.

[0033] Working Principle: First, the operator pulls handle 5 to move the first connecting pipe 6 outward, pouring the wastewater to be treated into the wastewater tank 4 through the first connecting pipe 6. After completion, the operator releases handle 5, and the reset spring 10 automatically moves the first connecting pipe 6 back to its initial position. At this time, the meter 9 in the wastewater tank 4 monitors the influent flow rate in real time and transmits the data to the AI ​​edge computing box 19. The water pump 12 pumps the wastewater through the water pipe 11 tangentially into the vortex dissolved air chamber 23, creating a vortex effect. Simultaneously, the DC power supply 18 supplies power to the honeycomb electrode assembly 15, and the electrode contamination sensor 14 monitors the electrode status in real time. When the scale thickness exceeds 1mm, the pulse backflushing cleaning program is automatically triggered. Inside the vortex dissolved air chamber 23, the multispectral water quality sensor 16 continuously monitors water quality parameters, and the AI ​​edge computing box 19 dynamically adjusts the electrolysis parameters based on the data. The ultrasonic transducer 24 operates under the power supply of the PEMFC micro fuel cell, preventing fibrous impurities from entangled. Its operating status is monitored in real time by the ultrasonic amplitude sensor 29. The scum generated during the treatment process is removed by a scraper 28 driven by a motor 26, while the microbubbles released by the microporous titanium tube aeration membrane 30 combine with the pollutants and float to the surface. The finally treated clean water enters the clean water tank 17 through a Venturi pneumatic reflux device 31. When the level sensor 20 detects that the water level has reached the set value, the operator can check the treatment effect through the observation port 3 and open the metal door 2 to take out the clean water.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
