Description

Technical Field

[0001] This invention relates to the field of water treatment equipment, and more specifically, to an integrated device for deep treatment and recycling of industrial wastewater. Background Technology

[0002] In recent years, the amount of industrial wastewater generated in China has been increasing year by year, and the environmental situation has become increasingly severe. The country has raised the requirements for external discharge standards. In addition, as one of the countries with scarce per capita water resources, my country also has corresponding restrictions on industrial water consumption. Therefore, it is of great significance to carry out in-depth treatment of industrial wastewater in order to achieve wastewater discharge in compliance with standards and reuse.

[0003] Traditional multi-stage purification and sludge removal equipment involves many steps, the equipment is scattered, occupies a lot of space, and the traditional discharge outlet has a single direction, which is inconvenient for wastewater treatment.

[0004] To address the aforementioned technical problems, Chinese Patent No. CN109110837B discloses an integrated device for deep treatment and recycling of industrial wastewater. The industrial wastewater recycling device manufactured using this invention facilitates multi-layer filtration and purification of wastewater, resulting in clean internal wastewater that can be reused. It also facilitates sludge collection and discharge control. However, in actual use, this device lacks a step for wastewater disinfection and does not utilize the strong oxidative killing effect of ozone on microorganisms. This leads to the proliferation of microorganisms in the recycled water, forming biofilms and slime on the surfaces of pipes, water tanks, and membrane components, exacerbating membrane fouling and equipment corrosion, shortening cleaning cycles, and increasing operating energy consumption. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an integrated device for deep treatment and recycling of industrial wastewater.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An integrated device for deep treatment and recycling of industrial wastewater includes a treatment tank. The top of the treatment tank is equipped with a sealing cover, and a sewage pipe is connected to one side of the top of the sealing cover.

A circulating water pipe is provided on the outer surface of the treatment tank near the bottom, and an air-blowing disinfection component for disinfecting the sewage is provided on the outer surface of the sewage pipe.

[0008] The air-blowing disinfection assembly includes an annular slide rail fixedly connected to the outer surface of the sewage pipe, a first air pump fixedly connected to the outer surface of the treatment tank, and a drive component disposed on the outer surface of the treatment tank opposite to the first air pump. A support plate is slidably connected inside the annular slide rail, and a first annular pipe is fixedly connected to one side of the support plate. A connecting pipe is uniformly fixedly connected to the outer surface of the first annular pipe, and an air distribution pipe is fixedly connected to the top of the connecting pipe. Multiple second air outlets are opened at the top of the air distribution pipe. An air delivery hose is connected to the output end of the first air pump, and one side of the air delivery hose is connected to the first annular pipe.

[0009] Furthermore, the driving component includes a servo motor fixed to the outer surface of the processing tank and an arc-shaped rack fixed to the outer surface of the first annular tube between two connecting tubes. The output end of the servo motor extends into the interior of the processing tank and is fixedly connected to a first gear. The first gear and the arc-shaped rack mesh with each other.

[0010] Furthermore, the first annular tube surrounds the sewage pipe, and the first annular tube and the air distribution pipe are located below the filter screen. The second air outlet sprays towards the bottom of the filter screen. The air supply hose and the interior of the first annular tube are interconnected. The first annular tube is interconnected with the interior of the air distribution pipe through a connecting pipe. The first air pump is connected to an external ozone generator. A rubber ring is provided at the connection between the pull rod and the sealing cover. The elastic deformation of the rubber ring fills the gap between the parts, effectively blocking the gas leakage path and significantly improving the overall airtightness of the device. A circulation component is provided on the top of the sealing cover, and a turbulence component is provided on the bottom of the outer surface of the first annular tube.

[0011] Furthermore, the circulation assembly includes an annular frame fixed at the center of the top of the sealing cap and a second air pump fixed on the outer surface of the processing tank on the same side as the servo motor. The output end of the second air pump is fixedly connected to a first return pipe, and a second annular pipe is fixedly connected to one side of the first return pipe. A plurality of first air outlets are evenly arranged on the outer surface of the second annular pipe. The output end of the second air pump is fixedly connected to the second return pipe. Four collection pipes are fixedly connected to the bottom of the annular frame, and the bottom of the collection pipes extends into the interior of the processing tank. The annular frame surrounds the pull rod.

[0012] Furthermore, the turbulence assembly includes two fixed rods fixed to the bottom of the outer surface of the first annular tube and a triangular block fixed to the bottom of the inner surface of the treatment tank. The outer surface of the fixed rods is fitted with a telescopic sleeve, the bottom of the telescopic sleeve is fixedly connected to a first spring, the bottom of the telescopic sleeve is fixedly connected to a turbulence plate, and the top of the outer surface of the telescopic sleeve is fixedly connected to a drive rod.

[0013] Furthermore, one side of the drive rod extends above the triangular block, which is an arc-shaped triangular slider concentric with the processing tank. The drive rod slides on the inclined surface of the triangular block, and the top of the first spring is fixedly connected to the bottom of the fixed rod.

[0014] Furthermore, the turbulence plate surrounds the drain pipe, and multiple slots are evenly distributed inside the turbulence plate.

[0015] Furthermore, a flow guiding component is provided at the bottom edge of the sealing cover. The flow guiding component includes an annular plate rotatably connected to the bottom of the sealing cover and a drive motor fixed at the top edge of the sealing cover. The output end of the drive motor is fixedly connected to a second gear. An annular rack is fixedly connected to the inner surface of the annular plate. Two circular holes are opened at the bottom of the annular plate. The height of the circular holes is lower than the height of the bottom end of the collection tube.

[0016] Furthermore, the output end of the drive motor extends into the interior of the annular plate, and the second gear meshes with the annular rack.

[0017] Furthermore, a cavity is formed between the annular plate and the sealing cover, and the bottom of the sewage pipe extends into the cavity. The interior of the annular plate is in communication with the interior of the sewage pipe. A mechanical sealing ring is provided at the rotatable connection between the annular plate and the sealing cover. The annular plate is located inside the treatment tank and above the filter screen.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution uses an air-blowing disinfection component. Ozone is ejected at high speed from inside the air distribution pipe through a second air outlet. The ejected ozone comes into contact with the filtered wastewater, and the high-speed airflow disperses the wastewater, effectively increasing the contact area between the wastewater and ozone. At the same time, the ozone column can flush the filter pores inside the filter screen, blowing out the particles inside the pores. This not only improves the disinfection efficiency and prevents microorganisms from multiplying in the circulating water, but also prevents the filter screen from clogging, effectively improving the filtration efficiency.

[0020] 2. This solution incorporates a circulation component. The collection pipe can simultaneously draw unused ozone into the interior of the annular frame, which then flows through the second and first return pipes into the interior of the second annular pipe. Finally, it is ejected through the first vent. The ozone forms bubbles in the filtered water, providing secondary disinfection. This not only improves the utilization rate of ozone and reduces the amount of ozone required, thus lowering economic costs, but also further enhances the disinfection effect of the filtered water and reduces the probability of large-scale microbial growth and reproduction.

[0021] 3. This solution uses a turbulence component, where a drive rod slides back and forth on the inclined surface of a triangular block, causing the telescopic sleeve to move up and down, which in turn causes the turbulence plate to move up and down in the water, stirring the water flow. This creates turbulence in the treatment tank, causing the ozone bubbles in the water to move irregularly and stay in the water for a longer time. The bubbles are broken into smaller bubbles, further increasing the contact area between ozone and water. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 7 An integrated device for deep treatment and recycling of industrial wastewater includes a treatment tank 1, a sealing cover 2 on the top of the treatment tank 1, a sewage pipe 3 connected to one side of the top of the sealing cover 2, a filter screen 6 fixedly connected to the top of the inner surface of the treatment tank 1, a sewage pipe 8 fixedly connected to the bottom of the filter screen 6, a piston 9 inserted into the top of the sewage pipe 8, a pull rod 7 fixedly connected to the top of the piston 9, a circulating water pipe 10 near the bottom of the outer surface of the treatment tank 1, and an air-blowing disinfection component 4 for disinfecting sewage on the outer surface of the sewage pipe 8.

[0039] like Figures 2-3 As shown, the air blowing disinfection assembly 4 includes an annular slide rail 411 fixedly connected to the outer surface of the drain pipe 8, a first air pump 41 fixedly connected to the outer surface of the treatment tank 1, and a drive component disposed on the outer surface of the treatment tank 1 opposite to the first air pump 41. A support plate 410 is slidably connected inside the annular slide rail 411. A first annular pipe 43 is fixedly connected to one side of the support plate 410. A connecting pipe 412 is uniformly fixedly connected to the outer surface of the first annular pipe 43. An air distribution pipe 413 is fixedly connected to the top of the connecting pipe 412. A plurality of second air outlets 46 are opened at the top of the air distribution pipe 413. An air supply hose 42 is connected to the output end of the first air pump 41. One side of the air supply hose 42 is connected to the first annular pipe 43.

[0040] The drive components include a servo motor 47 fixed on the outer surface of the processing tank 1 and an arc-shaped rack 48 fixed on the outer surface of the first annular tube 43 between two connecting tubes 412. The output end of the servo motor 47 extends into the interior of the processing tank 1 and is fixedly connected to a first gear 49. The first gear 49 and the arc-shaped rack 48 mesh with each other.

[0041] The first annular pipe 43 surrounds the drain pipe 8. The first annular pipe 43 and the air distribution pipe 413 are located below the filter screen 6. The second air outlet 46 sprays towards the bottom of the filter screen 6. The air supply hose 42 and the interior of the first annular pipe 43 are interconnected. The first annular pipe 43 is interconnected with the interior of the air distribution pipe 413 through the connecting pipe 412. The first air pump 41 is connected to the external ozone generator. A rubber ring is provided at the connection between the pull rod 7 and the sealing cover 2. The elastic deformation of the rubber ring fills the gap, effectively blocking the gas leakage path and significantly improving the overall airtightness of the device. A circulation component 44 is provided on the top of the sealing cover 2, and a turbulence component 45 is provided on the bottom of the outer surface of the first annular pipe 43.

[0042] During wastewater disinfection, the wastewater is transported to the treatment tank 1 through wastewater pipe 3. Filter screen 6 comes into contact with the wastewater, effectively filtering particulate matter. Simultaneously, the first air pump 41 is activated to deliver ozone through air delivery hose 42 to the inside of the first annular pipe 43. The ozone is then transported through connecting pipe 412 to the inside of air distribution pipe 413. Inside air distribution pipe 413, the ozone is ejected at high speed through the second air outlet 46. The ejected ozone comes into contact with the filtered wastewater, and the high-speed airflow disperses the wastewater, effectively increasing the contact area between the wastewater and ozone. At the same time, the ozone column can flush the filter pores inside filter screen 6, blowing out particles inside the filter pores. This not only improves the disinfection efficiency and prevents microorganisms from multiplying in the circulating water, but also prevents filter screen 6 from clogging, effectively improving filtration efficiency.

[0043] At the same time, the servo motor 47 is started to drive the first gear 49 to rotate in both directions. The first gear 49 drives the first annular tube 43 to swing back and forth inside the treatment tank 1 through the arc rack 48. It drives the air distribution pipe 413 to swing back and forth through the connecting pipe 412, so that the airflow ejected from the second air outlet 46 can thoroughly blow the bottom of the filter screen 6, increase the contact area between the airflow and the water flow, and thoroughly blow the filter holes inside the filter screen 6, further improving the filtration effect.

[0044] like Figures 4-5 As shown, the circulation assembly 44 includes an annular frame 446 fixed at the middle of the top of the sealing cover 2 and a second air pump 441 fixed on the outer surface of the processing tank 1 on the same side as the servo motor 47. The output end of the second air pump 441 is fixedly connected to a first return pipe 442. A second annular pipe 443 is fixedly connected to one side of the first return pipe 442. A plurality of first air outlets 444 are evenly arranged on the outer surface of the second annular pipe 443. The output end of the second air pump 441 is fixedly connected to a second return pipe 445. Four collection pipes 447 are fixedly connected to the bottom of the annular frame 446. The bottom of the collection pipes 447 extends into the interior of the processing tank 1. The annular frame 446 surrounds the pull rod 7.

[0045] During the continuous filtration process, not all ozone comes into contact with the wastewater, resulting in a large amount of ozone being discharged without directly interacting with the wastewater. This reduces the utilization rate of ozone, necessitating an increase in the amount of ozone added. To address this, a second air pump 441 is activated simultaneously with the filtration process. The second air pump 441 draws air from the inside of the annular frame 446 through the second return pipe 445, creating a negative pressure inside the four collection pipes 447. This generates a strong suction at the inlet, allowing the collection pipes 447 to simultaneously absorb any unused ozone into the annular frame 446. The ozone then enters the second annular pipe 443 through the second return pipe 445 and the first return pipe 442, and is finally ejected through the first air outlet 444. The ozone forms bubbles inside the filtered water, providing secondary disinfection. This not only improves the utilization rate of ozone and reduces the amount of ozone added, lowering economic costs, but also further enhances the disinfection effect of the filtered water, reducing the efficiency of microbial growth and reproduction.

[0046] like Figure 4 and Figure 6 As shown, the turbulence assembly 45 includes two fixed rods 453 fixed to the bottom of the outer surface of the first annular tube 43 and a triangular block 451 fixed to the bottom of the inner surface of the treatment tank 1. A telescopic sleeve 454 is sleeved on the outer surface of the fixed rods 453. A first spring 455 is fixedly connected to the bottom of the telescopic sleeve 454. A turbulence plate 456 is fixedly connected to the bottom of the telescopic sleeve 454. A drive rod 452 is fixedly connected to the top of the outer surface of the telescopic sleeve 454.

[0047] One side of the drive rod 452 extends above the triangular block 451. The triangular block 451 is an arc-shaped triangular slider concentric with the processing tank 1. The drive rod 452 slides on the inclined surface of the triangular block 451. The top of the first spring 455 is fixedly connected to the bottom of the fixed rod 453.

[0048] The turbulence plate 456 surrounds the drain pipe 8, and multiple slots are evenly distributed inside the turbulence plate 456.

[0049] When the recovered ozone is introduced into the water for secondary disinfection, the ozone bubbles rise rapidly in the water, resulting in short contact time between the ozone and the water and incomplete disinfection. Therefore, during secondary disinfection, the first annular tube 43 drives two fixed rods 453 to move back and forth. The fixed rods 453, through the telescopic sleeve 454, drive the drive rod 452 to swing back and forth. When the drive rod 452 slides to the top of the inclined plane of the triangular block 451, the first annular tube 43 rotates in the opposite direction. When the drive rod 452 moves to the bottom of the inclined plane of the triangular block 451, the first annular tube 43 rotates in the opposite direction again, causing the drive rod 452 to... The tube slides back and forth on the curved inclined surface, causing the telescopic sleeve 454 to move up and down, which in turn causes the turbulence plate 456 to move up and down in the water. The turbulence plate 456 rotates and moves vertically upward at the same time. When it rises to a certain height, it rotates again and descends. The water flow will pass through the slot, and the edge of the slot will continuously cut the water flow, generating a large number of small vortices. The vortices interact, stretch, and break up. The continuous reciprocating rotation of the first annular tube 43 can make the turbulence plate 456 move up and down with sufficient frequency and stroke, forming a continuous and strong disturbance to the water body, forming turbulence, causing the ozone bubbles in the water to move irregularly and stay in the water for a longer time. At the same time, the up and down movement of the turbulence plate 456 and the slot can directly cut, break up and disturb the ozone bubbles. The bubbles are broken into small bubbles, further increasing the contact area between ozone and water.

[0050] like Figure 7 As shown, a flow guiding component 5 is provided at the bottom edge of the sealing cover 2. The flow guiding component 5 includes an annular plate 52 rotatably connected to the bottom of the sealing cover 2 and a drive motor 51 fixed at the top edge of the sealing cover 2. The output end of the drive motor 51 is fixedly connected to a second gear 54. An annular rack 55 is fixedly connected to the inner surface of the annular plate 52. Two round holes 53 are opened at the bottom of the annular plate 52. The height of the round holes 53 is lower than the height of the bottom end of the collection tube 447.

[0051] The output end of the drive motor 51 extends into the interior of the annular plate 52, and the second gear 54 meshes with the annular rack 55.

[0052] A cavity is formed between the annular plate 52 and the sealing cover 2, and the bottom of the sewage pipe 3 extends into the cavity. The interior of the annular plate 52 is connected to the interior of the sewage pipe 3. A mechanical sealing ring is provided at the rotatable connection between the annular plate 52 and the sealing cover 2. The annular plate 52 is located inside the treatment tank 1 and above the filter screen 6.

[0053] When sewage enters the treatment tank 1, the sewage only comes into contact with a fixed position on the filter screen 6. This causes the position to become clogged quickly due to prolonged contact with water. Furthermore, the effective area of ​​the filter screen 6 for filtering sewage is small, resulting in low filtration efficiency. Therefore, when sewage enters the treatment tank 1, the drive motor 51 is turned on to drive the second gear 54 to rotate. The second gear 54 drives the annular plate 52 to rotate at the bottom of the sealing cover 2 through the annular rack 55, thereby driving the two round holes 53 to make synchronous circular motion. After the sewage enters the annular plate 52, the water will flow into the treatment tank 1 through the round holes 53. The change of the position of the round holes 53 can adjust the position of the sewage falling, so that the sewage can fully contact the surface of the filter screen 6, improve the efficiency of the filter screen 6, and increase the contact area between the sewage and ozone. When the sewage enters the treatment tank 1, since the height of the round holes 53 is lower than the height of the bottom of the collection pipe 447, the sewage is prevented from entering the collection pipe 447, which can avoid the high risk of water damage to the equipment. In addition, the sewage pipe 3 continuously enters water, and with the negative pressure at the bottom of the collection pipe 447, the unconsumed ozone cannot escape through the sewage pipe 3. The outflow of the circulating water pipe 10 and the inflow of the sewage pipe 3 are kept in dynamic balance.

[0054] Instructions for use: Sewage is transported to the inside of the treatment tank 1 through sewage pipe 3. The drive motor 51 is turned on to drive the second gear 54 to rotate. The second gear 54 drives the annular plate 52 to rotate at the bottom of the sealing cover 2 through the annular rack 55, thereby driving the two round holes 53 to make synchronous circumferential motion. The slow rotation of the annular plate 52 makes the sewage enter the treatment tank 1 evenly and dynamically, avoiding local overload and blockage of the filter screen 6.

[0055] The first air pump 41 is started to deliver ozone through the air delivery hose 42 to the inside of the first annular pipe 43. The ozone is then delivered through the connecting pipe 412 to the inside of the air distribution pipe 413. The ozone is ejected at high speed through the second air outlet 46 inside the air distribution pipe 413. The ejected ozone comes into contact with the sewage, and the high-speed airflow disperses the sewage, effectively increasing the contact area between the sewage and the ozone.

[0056] The second air pump 441 is activated. The second air pump 441 draws air into the interior of the annular frame 446 through the second return pipe 445, creating a negative pressure inside the four collection pipes 447. This creates a strong suction at the inlet, allowing the collection pipes 447 to simultaneously absorb any unused ozone into the interior of the annular frame 446. The ozone then enters the interior of the second annular pipe 443 through the second return pipe 445 and the first return pipe 442, and is finally sprayed out through the first air outlet 444. The ozone forms bubbles inside the filtered water, thus performing secondary disinfection on the filtered water.

[0057] During this closed-loop disinfection process, the first annular pipe 43 drives the two fixed rods 453 to move back and forth. The fixed rods 453 drive the drive rod 452 to swing back and forth through the telescopic sleeve 454, causing the drive rod 452 to slide back and forth on the inclined surface of the triangular block 451, driving the telescopic sleeve 454 to move up and down, which in turn drives the turbulence plate 456 to move up and down in the water, stirring the water flow. This causes the water flow to generate a dynamic turbulent field in the treatment tank 1, destroying the surface tension of the bubbles, maximizing the gas-liquid contact area, and causing the ozone bubbles in the water to move irregularly and stay in the water for a longer time.

[0058] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
