Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, and in particular to an industrial wastewater reverse osmosis water treatment device and treatment method. Background Technology
[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial production materials, intermediate products, by-products, and pollutants generated during production that are lost with the water. Reverse osmosis technology is used in industrial wastewater treatment to remove dissolved ions, microorganisms, and most organic matter from the wastewater. Before the wastewater is sent to the reverse osmosis system, industrial wastewater usually needs to undergo pretreatment, including steps such as filtration, sedimentation, and pH adjustment, to remove suspended solids and other large particulate matter and prevent them from clogging the reverse osmosis membrane. Wastewater filtration is one of the most important pretreatment processes.
[0003] However, existing industrial wastewater pretreatment methods have the following shortcomings:
[0004] 1. Industrial wastewater is filtered in stages by combining multiple individual filtration devices. Since the industrial wastewater is treated by multiple individual filtration devices, the particles in each individual filtration device need to be cleaned after treatment, which affects the overall filtration efficiency.
[0005] 2. Multiple individual filter units require manual cleaning while the machine is shut down and the water supply is cut off to remove particulate matter. Therefore, multiple individual filter units will prolong the downtime of the filter units and seriously affect the efficiency of industrial production.
[0006] Therefore, it is necessary to invent an industrial wastewater reverse osmosis water treatment equipment and method to solve the above problems. Summary of the Invention
[0007] To address the aforementioned problems, this invention provides an industrial wastewater reverse osmosis water treatment device, comprising a wastewater pretreatment unit. An inlet funnel is installed above the wastewater pretreatment unit, and a water storage tank is installed below it. The wastewater pretreatment unit has an internal chamber containing several filter components. Each filter component includes a filter plate, and multiple filter plates are evenly distributed along the wastewater conveying direction. Filter holes are formed on the filter plates, with the hole diameter decreasing from top to bottom. A scraping component for removing particulate matter is installed above each of the filter plates. A particle conveying component is located on one side of the wastewater pretreatment unit, including a particle conveying pipe fixedly connected to one side of the wastewater pretreatment unit. The wastewater pretreatment unit has multiple square openings for discharging the scraped particulate matter. A drive component for moving the scraper is located on the side of the wastewater pretreatment unit away from the particle conveying pipe. Guide grooves are formed on both sides of the inner wall of the chamber, and linkage adjustment components that cooperate with the drive component are installed in the guide grooves.
[0008] The scraping assembly includes a scraper that moves along the upper surface of the filter plate to scrape off particles. Multiple telescopic rods are symmetrically installed inside the particle conveying pipe, evenly distributed along the conveying channel. Each telescopic rod has a fixed sealing push block at its telescopic end. A rubber sealing ring is fixedly connected to the side of the sealing push block away from the telescopic rod. The sealing push block and the rubber sealing ring are inserted into a square opening and fit against the inner wall of the square opening. The sealing push block, through the cooperation of the rubber sealing ring and the square opening, seals the wastewater during transport.
[0009] In one possible implementation, the drive assembly includes a motor and lead screws. The motor is fixedly connected to the side of the wastewater pretreatment device away from the particle conveying pipe. Multiple lead screws are provided, each penetrating the wastewater pretreatment device and respectively disposed in corresponding guide grooves. The end of one of the lead screws is fixedly connected to the motor shaft. A first gear is fixedly connected to the driving lead screw located above the motor. Second gears are fixedly connected to the outer rings of multiple driven lead screws. The first gears are located outside the wastewater pretreatment device, and the second gears are located in the guide grooves. A toothed chain is commonly fitted around the outer rings of the multiple first gears. A guide block is threadedly connected to the outer ring of each lead screw, and the scraper is slidably connected to the guide block.
[0010] In one possible implementation, the linkage adjustment assembly includes a movable rack, a second gear meshing with the movable rack, a connecting plate fixedly connected to the side of the movable rack adjacent to the scraper, a spring plate fixedly connected to the bottom of the connecting plate, a first connecting rod fixedly connected to the side of the connecting plate adjacent to the scraper, a second connecting rod fixedly connected to the side of the first connecting rod away from the connecting plate, and a triangular push block fixedly connected to the side of the second connecting rod adjacent to the scraper, the inclined surface of the triangular push block being flush with the side of the scraper.
[0011] In one possible implementation, protrusions are fixedly connected to both sides of the scraper, and a groove is provided at the bottom of the scraper. Multiple cleaning brushes are fixedly connected in the groove. The cleaning brushes are evenly distributed along the length of the scraper, and the cleaning ends of the cleaning brushes are pressed against the upper surface of the corresponding filter plate.
[0012] In one possible implementation, guide components are provided on the sides of the two telescopic rods that are far apart from each other. The guide components include guide plates, both of which are fixedly connected to the particle conveying pipe. An inclined surface is provided on the side of the two guide plates that are close to each other. A particulate discharge port is provided on the side of the particle conveying pipe that is far away from the wastewater pretreatment device.
[0013] In one possible implementation, the guide groove is provided with an inclined backflow assembly, the inclined backflow assembly including a fixed inclined plate, the fixed inclined plate being fixedly connected in the guide groove, the inclined surface of the fixed inclined plate facing the scraper, and the guide block being slidably connected to the fixed inclined plate.
[0014] In one possible implementation, the wastewater pretreatment device is provided with clamping assemblies on both sides adjacent to the particle conveying pipe. The clamping assembly includes a limiting rod that passes through the wastewater pretreatment device and has its telescopic end extending into the chamber and intersecting the sealing push block. A spring is sleeved on the outer ring of the limiting rod.
[0015] This invention also discloses a method for treating industrial wastewater via reverse osmosis, comprising the following steps:
[0016] S1: Industrial wastewater is transported to the wastewater pretreatment device through the inlet funnel. The wastewater pretreatment device transports the filtered water to the water storage tank, and then the water storage tank discharges the filtered water. The particulate matter in the wastewater does not pass through the filter holes on the filter plate and adheres to the filter plate.
[0017] S2: Start the motor to drive multiple lead screws to rotate simultaneously. The multiple lead screws drive multiple sets of scraping components to scrape the particles on the filter plate at the same time.
[0018] S3: The scraping assembly is squeezed by the spring plate in the linkage adjustment assembly, so that the scraping assembly and the filter plate are tightly fitted.
[0019] S4: During the scraping process, the particles that diffused on both sides of the inner wall of the wastewater pretreatment device will be returned through the inclined backflow component;
[0020] S5: After the particles are scraped off, the scraping component pushes the sealing pusher to move, thereby releasing the seal between the sealing pusher and the wastewater pretreatment device and conveying the particles to the particle conveying pipe.
[0021] S6: The particles fall along the guide assembly in the particle conveying pipe and are discharged through the particle conveying pipe;
[0022] S7: Start the motor to rotate in reverse. During the return stroke, the scraping component contacts the scraping component through the triangular push block in the linkage adjustment component. The scraping component moves vertically upward under force, so that the scraping component separates from the filter plate during the return stroke.
[0023] The beneficial effects of this invention are as follows: 1. This invention uses filter components with different pore sizes to perform multi-stage continuous filtration of industrial wastewater. It also uses a single drive source to drive multiple scraping components to simultaneously scrape off the particles left on the filter components after filtration. The scraping components are linked and coordinated by the linkage adjustment component, the tilting and backflow component, and the particle conveying component to realize integrated sludge removal technology. This allows the water source and particles in the industrial wastewater to be filtered and scraped off at the same time. In addition, the guiding component in the particle conveying component allows the particles to be discharged evenly and quickly from the particle conveying component along the inclined surface of the guiding component. Compared with the traditional manual cleaning of particles, this invention greatly reduces the time for cleaning particles and improves the efficiency of operation.
[0024] 2. This invention adjusts the height of the scraping component during the forward and return phases using a linkage adjustment component. This achieves a tighter fit and separation distance between the scraping component and the filter component, increasing the scraping effect of the scraping component on the filter component and improving work efficiency. At the same time, there is no contact between the scraping component and the filter component during the return phase, preventing the scraping component from scraping the particles to the opposite position of the particle conveying component.
[0025] 3. In this invention, when the scraping component scrapes the filter component, the scraping component can move back and forth along the surface of the filter component. When the scraping component moves, the scraped particles are returned by the tilting backflow component, which prevents the particles from entering the guide area after scraping and causing blockage, thus affecting the movement of the scraping component. This is beneficial for the scraping component to complete the scraping work by driving the component along a preset travel path and time.
[0026] 4. The present invention includes a guide component in the particle conveying assembly, which guides the conveyed particles to fall and be discharged in an orderly manner along the surface of the guide component or through the distance between the guide components, thereby avoiding contact between the particles and the seals in the particle conveying assembly, reducing the contraction and stretching of the springs on the seals, and affecting the use of the seals.

[0039] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0040] Please see Figures 1-4 An industrial wastewater reverse osmosis water treatment device includes a wastewater pretreatment device 1, an inlet funnel 2 installed above the wastewater pretreatment device 1, and a water storage tank 3 installed below the wastewater pretreatment device 1. The wastewater pretreatment device 1 has an internal chamber 101, with the inlet funnel 2 and water storage tank 3 communicating with the chamber 101. Several filter components are fixedly installed in the chamber 101, each including a filter plate 13, for filtering industrial wastewater to separate the water source and particulate matter. The water source flows through the filter plate 13 to the water storage tank 3 and is then discharged from the water storage tank 3. The particulate matter in the wastewater does not pass through the filter holes on the filter plate 13 and adheres to the filter plate 13. Multiple filter plates 13 are provided, equidistantly distributed along the wastewater conveying direction. Each filter plate 13 has filter holes with decreasing apertures from top to bottom, enabling multi-stage continuous filtration of industrial wastewater.
[0041] Please see Figure 3 , Figure 10Each of the filter plates 13 is equipped with a scraping assembly for removing particulate matter. The scraping assembly includes a scraper 8, which is C-shaped. The scraper 8 moves along the upper surface of the filter plate 13 to scrape off particulate matter. Protrusions 801 are fixedly connected to both sides of the scraper 8. A groove is provided at the bottom of the scraper 8, and multiple cleaning brushes 802 are fixedly connected in the groove. The cleaning brushes 802 are evenly distributed along the length of the scraper 8. The bottom of the cleaning brush 802 is the cleaning end. The cleaning end of the cleaning brush 802 is pressed against the upper surface of the corresponding filter plate 13. The cleaning brush 802 is initially in contact with the filter plate 13. When the scraper 8 is working, the cleaning brush 802 moves in the direction of the scraper 8. The cleaning brush 802 can extend into the filter holes on the filter plate 13 to thoroughly clean the filter plate 13 and the filter holes, thus preventing the filter plate 13 from clogging when filtering industrial wastewater.
[0042] Please see Figure 8 , Figure 10 , Figure 11A particle conveying assembly is installed on one side of the wastewater pretreatment device 1. The particle conveying assembly includes a particle conveying pipe 4, which has a conveying channel inside. The conveying channel is used for collecting particles and discharging the collected particles centrally. The particle conveying pipe 4 is fixedly connected to one side of the wastewater pretreatment device 1. The wastewater pretreatment device 1 has multiple square openings for discharging scraped particles. Multiple telescopic rods 401 are symmetrically installed inside the particle conveying pipe 4. Springs are sleeved on the telescopic ends of the telescopic rods 401, so that the telescopic ends of the telescopic rods 401 are always in the extended state. The multiple telescopic rods 401 are evenly distributed along the conveying channel of the particle conveying pipe 4. Each telescopic end of the telescopic rods 401 is fixedly connected to a sealing push block 10. The vertical cross-section of the sealing push block 10 is the same size as the square opening. The sealing push block 10 moves into the square opening under the pushing force of the telescopic rods 401, thus separating the wastewater pretreatment device 1 from the particle conveying pipe 4. A sealed space is formed. A rubber sealing ring 1001 is fixedly connected to the side of the sealing push block 10 away from the telescopic rod 401. The sealing push block 10 and the rubber sealing ring 1001 are inserted into the square opening and fit against the inner wall of the square opening. The sealing push block 10 seals the wastewater conveying through the cooperation of the rubber sealing ring 1001 and the square opening. A guide assembly is provided on the side of the two telescopic rods 401 that is away from each other. The guide assembly includes a guide plate 402. The two guide plates 402 are fixedly connected to the particle conveying pipe 4. An inclined surface is opened on the side of the two guide plates 402 that is close to each other. The distance between the outlet ends of the two inclined surfaces is less than the distance between the two telescopic rods 401. Therefore, when the particles enter the particle conveying pipe 4 and slide down along the inclined surface of the guide plate 402, they will not fall onto the telescopic rod 401. A particle discharge port 403 is opened on the side of the particle conveying pipe 4 away from the wastewater pretreatment device 1. The particles slide along the inclined surface of the guide plate 402 and are finally discharged from the particle discharge port 403.
[0043] Please see Figure 1 , Figure 5 and Figure 8A drive assembly for moving the scraper 8 is provided on the side of the wastewater pretreatment device 1 away from the particle conveying pipe 4. The drive assembly includes a motor 5 and lead screws 6. The motor 5 is fixedly connected to the side of the wastewater pretreatment device 1 away from the particle conveying pipe 4. There are six lead screws 6, which are divided into one driving lead screw and five driven lead screws. All the lead screws 6 pass through the wastewater pretreatment device 1 and are respectively set in corresponding guide grooves 102. The end of the driving lead screw is fixedly connected to the rotating shaft of the motor 5. A first gear 601 is fixedly connected to the driving lead screw located above the motor 5. The outer sides of the multiple driven lead screws are... Each ring is fixedly connected with a second gear 603. The first gear 601 is located outside the wastewater pretreatment device 1, and the second gear 603 is located in the guide groove 102. The outer rings of multiple first gears 601 are jointly fitted with a toothed chain 602. The outer ring of the lead screw 6 is threadedly connected to a guide block 7. The scraper 8 is slidably connected to the guide block 7. When working, the motor 5 starts and drives the drive lead screw 6 to rotate. The first gear 601 on the drive lead screw 6 drives the toothed chain 602 to move. The toothed chain 602 drives the first gear 601 on the other driven lead screws 6 and the driven lead screw 6 to rotate.
[0044] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 Guide grooves 102 are provided on both sides of the inner wall of the chamber 101. A linkage adjustment component, which works in conjunction with the drive assembly, is installed in each guide groove 102. The linkage adjustment component includes a moving rack 9, a second gear 603 meshing with the moving rack 9, and a connecting plate 901 fixedly connected to the side of the moving rack 9 adjacent to the scraper 8. A spring plate 902 is installed inside the connecting plate 901. A first connecting rod 903 is fixedly connected to the side of the connecting plate 901 adjacent to the scraper 8, and a second connecting rod 904 is fixedly connected to the side of the first connecting rod 903 away from the connecting plate 901. A triangular push block 905 is fixedly connected to the side of the second connecting rod 904 adjacent to the scraper 8. The inclined surface is aligned with the side of the scraper 8. When the drive assembly is working, the lead screw 6 in the toothed chain 602 is rotated under force. At this time, the second gear 603 rotates in the direction of the lead screw 6, and the moving rack 9 meshing with it moves under force. The connecting plate 901, spring plate 902, first connecting rod 903, second connecting rod 904, and triangular push block 905 all move in the direction of the moving rack 9. After moving, the spring plate 902 contacts the protrusion 801. After they come into contact, the spring plate 902 presses the protrusion 801, and the protrusion 801 moves vertically downward under force. The bottom of the scraper 8 is in close contact with the upper surface of the filter plate 13.
[0045] Please see Figure 8 , Figure 9An inclined backflow assembly is provided in the guide groove 102. The inclined backflow assembly includes a fixed inclined plate 11, which is fixedly connected in the guide groove 102. The inclined surface of the fixed inclined plate 11 faces the scraper 8, and the guide block 7 is slidably connected to the fixed inclined plate 11.
[0046] Please see Figure 8 , Figure 10 The wastewater pretreatment device 1 is equipped with clamping components on both sides adjacent to the particle conveying pipe 4 to limit the sealing push block 10, so that the sealing push block 10 is always in the square opening when not under force. The clamping components include a limiting rod 12, which passes through the wastewater pretreatment device 1 and the telescopic end of the limiting rod 12 extends into the chamber 101 and is inserted on the sealing push block 10. A spring is sleeved on the outer ring of the limiting rod 12. When the scraping component moves under the drive of the drive component, after the scraper 8 of the scraping component comes into contact with the sealing push block 10, the sealing push block 10 moves after being pushed by the scraper 8. At this time, the scraper 8 releases the clamping component from the restriction of the sealing push block 10, and a gap is opened between the sealing push block 10 and the scraper 8. The scraped particle impurities enter the particle conveying pipe 4 through the gap.
[0047] This invention also discloses a method for treating industrial wastewater via reverse osmosis, comprising the following steps:
[0048] S1: Industrial wastewater is transported to wastewater pretreatment device 1 through inlet funnel 2. Multiple filter plates 13 in wastewater pretreatment device 1 perform multi-stage filtration treatment on industrial wastewater. After filtration, particulate impurities are attached to the upper surface of the corresponding filter plate 13.
[0049] S2: Start motor 5. The rotating shaft of motor 5 drives the driving lead screw and the driven lead screw to rotate simultaneously. After the lead screw 6 rotates under the drive of motor 5, the second gear 603 rotates in the direction of the lead screw 6.
[0050] S3: After the second gear 603 rotates, the moving rack 9, which meshes with the second gear 603, moves under force. The connecting plate 901, spring plate 902, first connecting rod 903, second connecting rod 904, and triangular push block 905 all move in the direction of the moving rack 9. After the spring plate 902 moves, it comes into contact with the protrusion 801. After they come into contact, the spring plate 902 squeezes the protrusion 801, and the protrusion 801 moves vertically downward under force. The bottom of the scraper 8 is in close contact with the upper surface of the filter plate 13 to scrape off particulate impurities.
[0051] S4: During the scraping process, when the scraper 8 slides along the inner wall of the guide groove 102 under the drive of the screw 6, the particles diffused on both sides of the inner wall of the wastewater pretreatment device 1 will be returned through the inclined surface of the fixed inclined plate 11.
[0052] S5: After the particles are scraped off, the scraper 8 and the sealing push block 10 come into contact with each other. The sealing push block 10 moves after being pushed by the scraper 8. The sealing push block 10 and the rubber sealing ring 1001 move under force. After the sealing push block 10 moves out of the square opening, a gap is opened between the sealing push block 10 and the scraper 8. The scraped particles and impurities enter the particle conveying pipe 4 through the gap.
[0053] S6: The particles fall along the inclined surface of the guide plate 402 in the particle conveying pipe 4 until they are discharged from the particle discharge port 403. At the same time, the wastewater source falls through the filter plate 13 into the water storage tank 3 and is discharged from the outlet below the water storage tank 3.
[0054] S7: After the scraper 8 scrapes the filter plate 13, it returns via the motor 5. During the return process, the shaft of the motor 5 drives the lead screw 6 and the second gear 603 to rotate in the opposite direction. The moving rack 9, connecting plate 901, spring plate 902, first connecting rod 903, second connecting rod 904, and triangular push block 905 are all reset. During the reset process, the spring plate 902 separates from the scraper 8, and the triangular push block 905 moves under the drive of the second connecting rod 904. The triangular push block 905 contacts the protrusion 801, and the protrusion 801 moves vertically upward along the inclined surface of the triangular push block 905. At this time, the scraper 8 separates from the filter plate 13.
