Description

Technical Field

[0001] This invention relates to the field of corrugated paper wastewater treatment, and particularly to a corrugated paper wastewater treatment device. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated paperboard, and further classified into five types according to the size of the corrugations: A, B, C, E, and F. Corrugated paper has been invented and used for over a century. It boasts advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. Over 80% of corrugated paper can be recycled. It is widely used for packaging food and digital products, is relatively environmentally friendly, and has a broad range of applications.

[0003] However, most existing treatments for corrugated paper wastewater involve large-scale treatment tanks. But treating small-scale wastewater with large tanks leads to wasted resources and difficulties in cleaning sediment from the tanks. Furthermore, the distance between the tanks makes real-time monitoring and emergency management difficult. Additionally, the filter plates need to be disassembled and cleaned when they become clogged, which is cumbersome and affects the treatment efficiency. Summary of the Invention

[0004] One object of the present invention is to provide a corrugated paper wastewater treatment device that at least solves any of the above-mentioned technical problems.

[0005] A further objective of this invention is to avoid wasting costs and to be applicable to small-scale wastewater treatment while saving space.

[0006] Another further objective of this invention is to improve the utilization of space and the effectiveness of wastewater treatment by creating hydraulic retention in the wastewater during treatment, thereby ensuring thorough mixing of the drugs.

[0007] The present invention provides a corrugated paper wastewater treatment device: including a base; a treatment device, a filtration mechanism, a first sedimentation section and a second sedimentation section; the treatment device is fixedly mounted on the base, and the treatment device includes a mixing chamber and a stirring paddle for stirring the mixed liquid, the stirring paddle being disposed at the bottom of the mixing chamber; The filtration mechanism includes a first filtration section, a second filtration section, and filtration components. The first and second filtration sections are arranged side by side and connected at their bottoms through a connecting cavity. Multiple filtration components are arranged in parallel from top to bottom. Each filtration component includes a drive shaft and two filter plates. The drive shaft passes through the first and second filtration sections. The two filter plates are fixedly connected to the drive shaft, and the plane of each filter plate is parallel to the drive shaft. The two filter plates are located within the first and second filtration sections, respectively. Each filter plate is equipped with a cleaning component, which is slidably connected to the side wall of the filtration section. The end of the cleaning component has a slider. The inner side walls of both the first and second filtration sections have grooves that match the corresponding sliders. The grooves are located on both sides of the filter plate, and the groove cross-section is arc-shaped. The second sedimentation section is disposed on one side of the first sedimentation section, the first sedimentation section is located between the second sedimentation section and the second filter section, and the first sedimentation section and the second sedimentation section and the second filter section are all connected to each other through an overflow port.

[0008] The cleaning assembly includes: a bearing wheel, a clamping plate, and a cleaning part. The clamping plate is clamped on the filter plate, and the bearing wheel is disposed at both ends of the clamping plate. The bearing wheel is fixedly connected to the slider. The two ends of the clamping plate are fixedly connected to the inner ring of the bearing wheel. The cleaning part is disposed in the middle of the clamping plate and is hinged to the clamping plate.

[0009] Limiting blocks are provided in the cavities of the first and second filtering sections, and the two ends of the limiting blocks near the filter plate are staggered.

[0010] The cleaning unit includes a scraper, a connecting block, a fixing block, and a spring. The scraper is located between the clamping plate and the drive shaft. The connecting block, the fixing block, and the spring are disposed between the scraper and the clamping plate. The fixing block is fixedly disposed in the middle of the clamping plate. The connecting block is fixedly disposed in the middle of the scraper. The connecting block is hinged to the fixing block. Both ends of the spring are fixedly connected to the clamping plate and the scraper, respectively.

[0011] Furthermore, the system includes a drainage system and a control system. The drainage system includes multiple discharge outlets, each equipped with a solenoid valve, for discharging wastewater or sediment as needed. The control system includes controls for controlling the speed of the agitator, the amount of oxidant added, and the status of the multi-layer filter screen in the filtration zone. The filtration zone includes multiple filter layers, which are connected to the sedimentation zone and the water passage zone via adjustable valves to adapt to filtration needs under different water quality conditions.

[0012] Furthermore, the control system also includes: Wastewater quality monitoring module: used to monitor the concentrations of suspended solids, COD, and BOD in wastewater; Agitator control module: Adjusts the rotation speed of the agitator in real time based on the concentration of suspended solids, COD concentration and water flow in the wastewater; Oxidant addition module: Automatically adjusts the amount of oxidant added based on the concentration of pollutants in the wastewater; Filter cleaning control module: Controls the cleaning cycle and cleaning method of the filter screen according to the degree of filter screen contamination and the amount of wastewater treated.

[0013] Further, the process includes the following steps: Wastewater treatment parameter control: Adjusting the speed of the agitator, the amount of oxidant added, and the cleaning cycle of the filter screen based on real-time monitored wastewater quality data.

[0014] Furthermore, the multi-layer filtration control dynamically adjusts the activation status of each filter layer based on wastewater flow rate, pollutant concentration, and water pressure to improve treatment efficiency. Furthermore, it also includes the following steps: Filter cleaning cycle control: Adjust the cleaning cycle and select a suitable cleaning method according to the degree of filter contamination and wastewater treatment volume; The technical effects and advantages of this invention are as follows: This invention utilizes an integrally molded wastewater treatment device, including a mixing tank. A stirring paddle capable of rotating and agitating wastewater is located at the bottom of the mixing tank, and a dosing pipe is positioned below the stirring paddle. Chemicals are added through the dosing pipe while the stirring paddle agitates the wastewater, directly mixing with the wastewater and saving mixing time. After mixing, the wastewater flows through an overflow port into a first filtration chamber for initial filtration. The filtered liquid then flows through a lower connecting chamber into a second filtration chamber for a second filtration. After filtration, the wastewater passes through a first filter plate on the overflow port into a first sedimentation section for sedimentation. After sedimentation, it passes through a second filter plate on the upper overflow port for further filtration. During filtration, if the filter plates become clogged, the filter plates in both the first and second filtration sections are connected to a drive shaft. When a large amount of sediment is generated on the filter plate in the first filtration section, the filter plate will become clogged. Because the filter plate has a double-layer structure, it requires disassembly for cleaning. The unloading process is cumbersome and cleaning is inconvenient. This application uses a servo motor to drive the drive shaft to rotate, thereby flipping the filter plate in the first filtration section. At the same time, the cleaning component moves linearly along the slide along the filter plate to scrape off the attached material on the upper part, preventing the filter plate from clogging. When the filter plate is tilted, the cleaned clogging sediment falls to the bottom and is discharged. Simultaneously, for the second filtration section, when the filter plate in the first filtration section rotates, the filter plate in the second filtration section also rotates. The purpose of rotation is to make the floating material mixed at the bottom float to the top through the flipping of the filter plate, so as to carry out bidirectional treatment and multiple uses in one rotation. Finally, it enters the second sedimentation section. After sedimentation, the supernatant is discharged through the upper flange drain port, and the sediment is discharged through the lower sewage outlet, thereby completing the sewage treatment. At the same time, the treatment sections are close to each other, which can respond to emergencies in a timely manner.

[0015] It should be further noted that at least one flange interface is provided at the bottom of the stirring chamber, the connecting chamber, the first sedimentation section, and the second sedimentation section. A water inlet pipe connection port is provided at the bottom of the mixing tank, and sewage is injected from the bottom of the mixing tank, so that the sewage can be mixed with the agent immediately. A flange drain pipe is provided on one side of the connecting chamber to discharge the sedimented dirt and avoid blockage of the connecting chamber. At the same time, a drain flange is provided on the lower side of the first sedimentation section for sewage discharge, which facilitates the cleaning of sediment.

[0016] The system can respond to water quality fluctuations in real time, automatically adjusting the stirring intensity and oxidant dosage to ensure that pollutants are always in the optimal removal state. This avoids the low treatment efficiency problem of traditional fixed parameter modes. The linkage between stirring and dosing ensures that the oxidant and pollutants are fully mixed and reacted, improving the chemical reaction rate and mass transfer efficiency. The oxidant is added based on the real-time concentration (COD / BOD), avoiding "overdosing" (causing waste and secondary pollution) or "underdosing" (leading to substandard effluent), ensuring that the effluent quality is stable within or even better than the set standard. The stirring paddle speed is adjusted according to actual needs, avoiding unnecessary energy waste. On-demand cleaning of the filter screen is also more energy-efficient and water-saving than timed cleaning. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1 This embodiment provides a corrugated paper wastewater treatment device, which includes: a base 1, a treatment device, a filtration mechanism, a cleaning component, a first sedimentation section 5, and a second sedimentation section 6. The treatment device is fixedly mounted on the base 1 and includes a mixing chamber. A stirring paddle 10 for mixing liquids is provided at the bottom of the mixing chamber. The stirring paddle 10 is driven by a servo motor via a rotating shaft 12. It should be noted that this driving method is a conventional configuration and will not be elaborated further here. The filtration mechanism has a first filtration section 3 and a second filtration section 4, which are connected by a... The sealing baffle 305 is divided into equal volumes, and the bottoms of the first filter section 3 and the second filter section 4 are connected by a connecting cavity 304. Each of the first filter section 3 and the second filter section 4 is provided with several equally spaced filter plates. Different mesh sizes of filter plates 13 are provided on the filter plates as needed. The filter plates are fixed to the fixing parts on the inner sidewall of the cavity. The cleaning component is slidably mounted on the filter plate 13. The inner walls of the first filter section 3 and the second filter section 4 are provided with sliding grooves 3021 for the cleaning component to slide. The sliding grooves 3021 are arc-shaped, and the two ends of the sliding grooves 3021 are arranged vertically oppositely. The cleaning assembly includes: a bearing wheel 17, a clamping plate 18, and a cleaning section. The bearing wheel 17 is disposed within the slide groove 3021. It should be noted that a slider can be disposed within the slide groove 3021. The outer ring of the bearing wheel 17 is fixedly connected to the slider, while the inner ring can rotate freely. Both ends of the clamping plate 18 are fixedly connected to the inner ring of the bearing wheel 17. When the servo motor 14 drives the filter plate to rotate, the bearing wheel 17 moves along the slide groove 3021. Simultaneously, the inner ring of the bearing wheel 17 changes angle with the filter plate 13. The movement of the bearing wheel 17 drives the clamping plate 18 to rotate within the slide groove 3021. The filter plate 13 moves linearly on its frame, thereby pushing the scraper 19 of the cleaning part to move. Limiting blocks 16 are provided in the cavities of the first filter part 3 and the second filter part 4. The limiting blocks 16 are staggered vertically. The limiting blocks 16 are provided to avoid large rotation amplitude. The limiting blocks 16 are located on both sides of the filter plate 13 and are fixedly connected to the side walls of the first filter part 3 and the second filter part 4. The cleaning part includes: scraper 19, spring 21. A connecting block 1901 is provided in the middle of the scraper 19. The connecting block 1901 is hinged to the fixing block 20 provided in the middle of the clamping plate.The spring 21 is disposed between the clamping plate 18 and the scraper 19. Through the upper hinge and the cooperation of the spring, the scraper can maintain elastic pushing force while pushing the surface material. The elastic setting can better scrape off the stains. The two ends of the spring 21 are fixedly connected to the clamping plate 18 and the scraper 21 respectively. The cleaning part is hinged to the clamping plate 18. The first sedimentation part 5 is disposed between the second sedimentation part 6 and the second filter part 4. The first sedimentation part 5, the second sedimentation part 6, and the second filter part 4 are all connected through the overflow port 7 provided at the upper part between them. The first filter 8 and the second filter 9 are respectively provided at the overflow port 7. The function of the first filter 8 and the second filter 9 is to filter floating objects and larger particles. In use, the sieve mesh of the second filter 9 can be set to be larger than that of the first filter 8. Through layer-by-layer fine sieving, the supernatant after sedimentation is gradually filtered through the upper overflow port 7, and the lower sediment is discharged from the flange interface on the lower side. Figure 4 As shown, a dosing pipe 11 is provided below the stirring paddle 10. When the stirring paddle 10 rotates and stirs, the dosing pipe 11 can directly mix from bottom to top along the stirring direction of the stirring paddle 10, making the mixing more thorough. The bottom of the mixing chamber, the connecting chamber 304, the first sedimentation section 5 and the second sedimentation section 6 are all provided with at least one flange interface. The purpose of installing at least one flange interface is to discharge sewage through the sewage pipe 301 and discharge the flocculated impurities settled in each part. It should be noted that the first filtration section 3 and the second filtration section 4 can also be equipped with coarse filters, micro filters, activated carbon filters and / or membrane filters for sewage treatment. Furthermore, it should be noted that both the first filter section 3 and the second filter section 4 are equipped with several equally spaced filter plates. A drive shaft 15 is provided in the middle of each filter plate, passing through both the first and second filter sections 4. Each filter plate is fixedly connected to the drive shaft 15. A servo motor 14 is provided on either side of the first filter section 3 and the second filter section 4 to drive the drive shaft 15 to rotate. The servo motor 14 drives the drive shaft 15 to rotate, thereby causing the filter plates 13 to flip. This flips the filter plates 13 in the first filter section 3, allowing the clogged sediment to fall to the bottom and be discharged. Simultaneously, for the second filter section, when the filter plates 13 in the first filter section 3 rotate, the filter plates 13 in the second filter section 4 also rotate. The purpose of this rotation is to allow the floating matter mixed at the bottom to float to the surface, providing bidirectional processing and multiple uses. Limiting blocks 16 are provided on the side walls of the first filter section 3 and the second filter section 4. The function of the limiting blocks 16 is to prevent the filter plates 13 from deflecting excessively, thereby avoiding affecting the filtration effect.

[0033] As a preferred embodiment, it should be further explained that a fixing frame 202 is provided on the overflow port 7 near the upper part of the mixing chamber. The fixing frame 202 can be used to install a temporary dosing box for adding other agents. At the same time, a water pump can also be installed on the fixing frame 202. When the water level in the mixing chamber does not reach the overflow port 7, water is supplied to the filtration mechanism by the water pump.

[0034] As a preferred embodiment, it should be further explained that a fixing seat 101 is provided on the outside of the first sedimentation section 5 or the second sedimentation section 6 near the flange interface. Auxiliary equipment is installed through the fixing seat 101 to assist in the discharge of sediment in the sedimentation tank. If the sediment in the sedimentation section is inconvenient to discharge, a high-pressure pump can be installed to backwash the bottom of the sedimentation section to prevent the flange outlet from being blocked.

[0035] Example 2: A cleaning roller is provided on the side of the clamping plate facing the filter plate. When the clamping plate moves, the cleaning roller rotates due to the friction between its two ends and the filter plate. At the same time, the middle part of the cleaning roller further cleans the filter plate. It should also be noted that gears are provided at both ends of the cleaning roller, and the filter plate is provided with tooth grooves corresponding to the gears. The rotation of the cleaning roller is driven by the meshing of the gears and tooth grooves.

[0036] Based on the above-mentioned equipment and the corresponding corrugated paper wastewater treatment equipment, the following steps are included: Wastewater Introduction and Preliminary Mixing: Wastewater generated during corrugated paper production is introduced into the preliminary mixing tank 2 of the treatment unit through the inlet pipe 201 located at the bottom, flowing from bottom to top. The mixing tank 2 is equipped with a stirring paddle 10 and a dosing pipe 11 at the bottom. The wastewater introduced through the inlet pipe is directly mixed with the chemicals injected through the dosing pipe 11, and the stirring paddle 10 further accelerates the mixing effect. During this process, the intelligent control system automatically adjusts the rotation speed of the stirring paddle 10 according to the inlet water quality and controls the amount of chemicals added through the dosing pipe 11. The rotation speed of the stirring paddle is given by the following control function; By monitoring the COD concentration, suspended solids concentration, and flow rate of wastewater in real time, the system can dynamically adjust the rotation speed of the agitator to ensure thorough mixing of wastewater and chemicals.

[0037] Oxidant pretreatment and coagulation: In the treatment unit, an oxidant is first added for pretreatment, followed by the addition of a flocculant. The oxidant is mainly used to decompose organic matter in the wastewater, reducing its pollution level. Typically, hydrogen peroxide, ozone, or oxygen can be used as the oxidant. After the oxidant is added, the agitator 10 continues to stir, ensuring the wastewater reacts fully with the reagent. The oxidant completes its reaction after 1-2 hours. Then, the flocculant is added for coagulation, forming flocculent precipitates.

[0038] The oxidant dosage and agitator speed are controlled by the following function: Filtration and Sedimentation: After oxidation and coagulation, the solidified organic matter in the wastewater enters the first filtration section 3 through the overflow port 7 above, and then enters the second filtration section 4. In the first and second filtration sections, the wastewater is filtered through a coarse filter, a micro filter, an activated carbon filter, and / or a membrane filter to remove suspended solids and large particulate pollutants. After filtration, the water flows through the overflow port into the first sedimentation section 5 for sedimentation treatment. The filtration process is optimized by controlling the following function: Neutralization Treatment: After sedimentation in the first sedimentation section 5, the water flows into the second sedimentation section 6 for neutralization treatment to adjust its pH value. At this time, the intelligent control system automatically adjusts the addition of acidic or alkaline substances based on the pH value of the water flow. The neutralization process involves adding alkaline substances such as sodium hydroxide and calcium hydroxide, or acidic substances such as sulfuric acid and hydrochloric acid, to adjust the pH of the water to neutral or near-neutral. The neutralization treatment is controlled by the following formula: e. Final drainage: Finally, the treated clean water is discharged through drain 602.

[0039] It should be further noted that the oxidant can be hydrogen peroxide, ozone, or oxygen.

[0040] It should be further noted that the filtration system includes a coarse filter, a micro filter, an activated carbon filter, and / or a membrane filter.

[0041] It should be further explained that the neutralization process involves adding alkaline or acidic substances to the treated water to adjust its pH to neutral or near neutral.

[0042] It should be further noted that the alkaline substances can be sodium hydroxide or calcium hydroxide, and the acidic substances can be sulfuric acid or hydrochloric acid.

[0043] It should be further explained that this also includes adding auxiliary agents to the treatment device to enhance the wastewater treatment effect. These auxiliary agents can be flocculants, bactericides, or disinfectants. It should also be noted that this application has a maximum treatment capacity of 6 T / D (0.25 T / H) for small-scale industrial wastewater biochemical treatment, a hydraulic retention time of 8 hours, and an effective COD removal rate of up to 90%. The equalization tank can be reserved to adjust the amount of wastewater for one day.

[0044] Working principle of this invention: In use, an integrated wastewater treatment device is installed, including a mixing tank 2. A stirring paddle 10 capable of rotating and agitating wastewater is installed at the bottom of the mixing tank 2. A dosing pipe 11 is located below the stirring paddle. While the stirring paddle 10 rotates and agitates the wastewater, the dosing pipe 11 adds chemicals, directly mixing with the wastewater, thus saving mixing time. After mixing, the liquid flows through the overflow port 7 into the first filtration chamber 302 for the first filtration. The filtered liquid then flows through the lower connecting chamber 304 into the second filtration chamber 303 for the second filtration. After filtration, the liquid passes through the first filter plate 8 installed on the overflow port 7. The material enters the first sedimentation section 5 for sedimentation, and after sedimentation, it is filtered again through the second filter 9 set in the overflow port 7 above. Simultaneously, the filter plates 13 set in both the first and second filter sections 3 are connected to the rotating shaft. When a large amount of sediment is generated on the filter plate of the first filter section 3, the filter plate 13 will become clogged. Since the filter plate 13 has a double-layer structure, it requires disassembly for cleaning, which is cumbersome and inconvenient. This application uses a servo motor 14 to drive the rotating shaft to rotate, thereby flipping the filter plate 13 and the filter plate in the first filter section 3, thus simultaneously cleaning... The component moves linearly along the groove on the filter plate, thereby scraping off the deposits on the upper surface of the filter plate 13 and preventing clogging. When the filter plate 13 is tilted, the cleaned clogging sediment falls to the bottom for discharge. Simultaneously, for the second filtration section, when the filter plate in the first filtration section 3 rotates, the filter plate 13 in the second filtration section 4 also rotates. The purpose of rotation is to allow the floating matter mixed at the bottom to float to the top through the flipping of the filter plate 13, performing bidirectional treatment and multiple uses in one rotation. Finally, it enters the second sedimentation section 6. After sedimentation, the supernatant is discharged through the flange drain port 602 provided above. The liquid is discharged, and the sediment is discharged through the drain port 601 provided below, thus completing the sewage treatment. At least one flange interface is provided at the bottom of the stirring chamber, the connecting chamber 304, the first sedimentation section 5 and the second sedimentation section 6. The bottom of the mixing tank 2 is provided with a water inlet pipe 201 for connection. Sewage is injected from the bottom of the mixing tank 2, and the sewage can be mixed with the agent immediately. A flange drain pipe 301 is provided on one side of the connecting chamber 304 to discharge the sediment and prevent the connecting chamber 304 from being blocked. At the same time, a drain flange is provided on the lower side of the first sedimentation section 5 for sewage discharge, which facilitates the cleaning of sediment.Furthermore, it should be noted that the filter plates 13 in the first filter section 3 and the second filter section 4 are both fixedly connected to the drive shaft 15. When a large amount of sediment is generated on the filter plate 13 of the first filter section 3, the filter plate 13 will become clogged. Since the filter plate 13 has a double-layer structure, it needs to be disassembled for cleaning, which is cumbersome and inconvenient. In this application, the drive shaft 15 can be rotated by the servo motor 14, thereby flipping the filter plate 13. This flips the filter plate 13 in the first filter section 3, causing the clogged sediment to fall to the bottom under the force of the water flow and its own downward gravity, and then be discharged through the drain pipe. Simultaneously, for the second filter section 4, when the filter plate 13 in the first filter section 3 rotates, the filter plate 13 in the second filter section 4 also rotates. The purpose of rotation is to allow the floating matter mixed at the bottom to float to the surface through the flipping of the filter plate 13. This floating matter is fully reacted, and when it passes through the connecting cavity, it is fully reacted, thus achieving bidirectional processing in the first and second filter sections. A single rotation of the drive shaft can achieve two effects simultaneously: cleaning the filter plate and preventing clogging of the filter holes. Limiting blocks 16 are provided on the side walls of the first filter section 3 and the second filter section 4. The function of the limiting blocks 16 is to prevent the filter plate 13 from excessively deflecting, thereby affecting the filtration effect.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
