Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an industrial wastewater flocculation treatment device and its usage method. Background Technology

[0002] Industrial wastewater contains a large amount of suspended particulate matter, colloidal impurities, and soluble pollutants. Flocculation is one of the core processes in the pretreatment and advanced treatment of industrial wastewater. By adding flocculants to the wastewater, the fine impurities and colloidal particles in the water collide and agglomerate to form flocs with larger particle sizes, thereby achieving the separation of pollutants from the water and laying the foundation for subsequent filtration, discharge, or reuse.

[0003] Currently, existing industrial wastewater flocculation treatment devices generally adopt a step-by-step treatment mode of "flocculation first, then separation". That is, the wastewater and flocculant are first mixed and reacted in the flocculation tank. After the flocculation reaction is completely completed, the mixture containing a large amount of flocculants is then transported to the separation equipment to separate the flocculants from the clean water.

[0004] However, in actual operation, since the flocculation reaction does not separate the flocs, the concentration of flocs in the flocculation tank will gradually increase as the flocculation reaction continues. On the one hand, this will increase the viscosity of the water, hindering the wastewater from fully mixing and colliding with the unreacted flocculant, reducing the rate and effect of the flocculation reaction, and causing some fine impurities to fail to coagulate effectively, affecting the subsequent separation effect. On the other hand, excessively high concentrations of flocs are prone to collision and breakage, forming fine flocs that are difficult to separate effectively, and may even cause secondary pollution, increasing the load on subsequent treatment.

[0005] Therefore, the present invention provides an industrial wastewater flocculation treatment device and its usage method. Summary of the Invention

[0014] A method of using an industrial wastewater flocculation treatment device, the method comprising the following steps: A1. Inject industrial wastewater into the flocculation tank and add flocculant, start the aeration pipe to aerate, and at the same time drive the drive motor to rotate the transmission shaft, so that the support cylinder rotates in the forward direction. A2. When the support cylinder rotates in the forward direction, the spiral baffle pushes the water upward and overflows into the guide channel.

This invention, by incorporating a filter plate, a return pipe, and a baffle plate, effectively solves the technical problem of the gradually increasing floc concentration affecting the flocculation effect in existing devices operating under a flocculation-separation mode. During the flocculation reaction, the water circulation is driven by the rotation of the baffle plate without waiting for the reaction to completely end. This allows the floc-containing water to flow through the filter plate, intercepting and separating the flocs in real time, reducing the floc concentration in the water, preventing floc accumulation from increasing water viscosity and hindering the thorough mixing of the reagent and wastewater, and preventing secondary pollution caused by floc collision and breakage. The filtered water is returned to the flocculation area through the return pipe, achieving wastewater recycling treatment. This ensures continuous and efficient flocculation reaction and improves reagent utilization, solving the drawbacks of poor flocculation effect and high subsequent treatment load in traditional step-by-step treatment modes, and improving the stability and compliance rate of wastewater flocculation treatment.

[0016] 2. This invention, by incorporating a scraping structure, a tapping structure, and a magnetic linkage structure, achieves automated continuous operation of the device, significantly reducing manual maintenance costs and operating energy consumption. During the filtration process, the scraping and tapping structures work together to thoroughly clean residual flocs from the filter surface and filter pores, preventing pore blockage, ensuring smooth filtration and stable circulation flow, and extending the service life of the filter structure. Simultaneous control of water circulation, filter structure lifting and lowering, and scraping actions simplifies the overall structure of the device and reduces manufacturing costs. Furthermore, the automated slag discharge and unclogging design enables unattended continuous operation, adapting to the needs of large-scale industrial wastewater treatment and further improving treatment efficiency and operational stability.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 9 As shown, the industrial wastewater flocculation treatment device of the present invention includes a flocculation section, a support section, a flow disturbance mechanism, a flow guiding mechanism, a return flow mechanism, and a filtration mechanism.

[0022] The flocculation section includes a flocculation tank 1 and an aeration pipe 11. The aeration pipe 11 is arranged in a ring inside the flocculation tank 1. During aeration, air is introduced into the sewage in the flocculation tank 1. On the one hand, the disturbance generated by the rising bubbles enhances the mixing, collision and flocculation reaction between the sewage and the flocculant, thereby improving the floc formation effect. On the other hand, the aeration and oxygenation improve the sewage quality conditions and inhibit the formation of an anaerobic environment. At the same time, the swirling airflow formed by the inclined exhaust can assist in turbulence and flow guidance. Together with the overall structure of the flocculation tank 1, it achieves a more stable and efficient flocculation pretreatment.

[0023] The exhaust end of the aeration pipe 11 is inclined. Multiple exhaust ends of the aeration pipe 11 are arranged in a ring along the axis of the flocculation tank 1. During aeration, the liquid in the flocculation tank 1 is pushed upward and surges toward the center of the flocculation tank 1 by the thrust.

[0024] The support includes a support frame 5 and a collection trough 12. The collection trough 12 is fixedly installed on the outer wall of the flocculation tank 1, and the support frame 5 is fixedly installed on the upper end face of the collection trough 12. The upper end of the collection trough 12 is provided with an opening.

[0025] The turbulence-disrupting mechanism includes a support cylinder 13 and a turbulence-disrupting plate 14. The support cylinder 13 is rotatably installed on the inner wall of the flocculation tank 1, wherein the axis of the support cylinder 13 coincides with the axis of the flocculation tank 1.

[0026] The baffle 14 is fixedly installed on the radial outer wall of the support cylinder 13. The baffle 14 is spirally arranged on the outer wall of the support cylinder 13. When the support cylinder 13 rotates in the forward direction, it pushes the liquid inside the flocculation tank 1 upward, causing the liquid in the middle of the flocculation tank 1 to surge upward. When the support cylinder 13 rotates in the reverse direction, it pushes the liquid inside the flocculation tank 1 downward, causing the liquid surface in the middle of the flocculation tank 1 to sink downward.

[0027] The flow guiding mechanism includes a flow guiding channel 4 and a guide and connecting return pipe 26. The flow guiding channel 4 is fixedly installed on the upper end face of the collection tank 12. Multiple flow guiding channels 4 are evenly arranged in a ring on the outer wall of the collection tank 12. One end of the flow guiding channel 4 extends to the top of the flocculation tank 1, and the other end of the flow guiding channel 4 extends to the top of the collection tank 12.

[0028] The collection tank 12 and the inner cavity of the flocculation tank 1 are connected by a return pipe 26, and the liquid inside the collection tank 12 flows back to the interior of the flocculation tank 1 through the return pipe 26.

[0029] When the support cylinder 13 rotates in the forward direction, the spiral baffles 14 on its outer wall push the liquid inside the flocculation tank 1 upward, causing the liquid in the middle of the tank to continuously surge upward, the liquid level rises and overflows into the guide channel 4, and is guided into the collection tank 12 through the guide channel 4, and then flows back to the inner cavity of the flocculation tank 1 through the return pipe 26, forming a circulating flow and enhancing the mixing and flocculation effect of sewage and chemicals; when the support cylinder 13 rotates in the reverse direction, the baffles 14 push the liquid inside the flocculation tank 1 downward, causing the liquid level in the middle to sink downward, and the liquid cannot enter the guide channel 4, thereby cutting off the liquid passage between the guide channel 4, the collection tank 12 and the return pipe 26, and stopping the circulating flow of liquid.

[0030] The filtration mechanism includes a guide frame 21 and a filter plate 3. The guide frame 21 is slidably installed on the inner wall of the collection tank 12, and the filter plate 3 is fixedly installed on the outer wall of the guide frame 21. The filter plate 3 is inclined and the guide frame 21 provides support for the filter plate 3.

[0031] When the support cylinder 13 rotates in the forward direction, the liquid in the flocculation tank 1 enters the collection tank 12 through the guide channel 4. The liquid flows through the inclined filter plate 3. Under the support of the guide frame 21, the filter plate 3 filters and intercepts the flocculants in the circulating liquid, realizing sewage flocculation treatment. When the support cylinder 13 rotates in the reverse direction, the liquid circulation passage is closed. At this time, the aeration pipe 11 stops aeration to avoid bubble disturbance affecting the settling and discharge of flocculants. At the same time, the guide frame 21 slides upward along the inner wall of the collection tank 12, driving the filter plate 3 to slide out of the collection tank 12, so that the intercepted flocculants can be discharged smoothly, completing the automatic slag discharge.

[0032] During the flocculation process, reducing the floc content in flocculation tank 1 can reduce the interference of floc accumulation on water flow and reagent mixing, avoid floc breakage and secondary pollution, and improve flocculation reaction efficiency and effluent stability. The filter plate 3 and guide frame 21 realize automatic interception and capture of flocs, which can continuously separate flocs and reduce the load on subsequent treatment. With the automatic slag discharge structure that drives the filter plate 3 to slide out of the collection tank 12 when the guide frame 21 rotates in the opposite direction, the filter plate can be prevented from clogging, ensuring long-term stable operation of the device and reducing manual cleaning. The filtered liquid is returned to flocculation tank 1 through collection tank 12 and return pipe 26, which can realize sewage recycling treatment, improve reagent utilization and flocculation effect, improve water resource utilization, and reduce overall treatment energy consumption and sewage discharge.

[0033] During the flocculation process, reducing the floc content in flocculation tank 1 can reduce the interference of floc accumulation on water flow disturbance and reagent mixing, avoid floc breakage and excessive concentration causing deterioration of working conditions, and provide a basic condition for stable and efficient flocculation. Automatic interception and capture and automatic slag discharge can separate and remove flocs in real time, prevent filter plate 3 from clogging, realize continuous automated operation, and promote the floc reduction effect, improve the stability and treatment efficiency of the device. The filtered liquid is returned to flocculation tank 1 through return pipe 26, which can stably maintain the liquid volume in the tank, prevent the floc concentration from increasing due to liquid reduction, and maintain a stable liquid level, ensuring that the liquid continues to surge stably when the support cylinder 13 rotates in the forward direction, so that the flocs are reliably entrained and smoothly discharged, realizing dynamic balance and continuous stable operation.

[0034] The upper end face of the support frame 5 is rotatably mounted with a top pressure frame 7 via a torsion spring. After rotating the top pressure frame 7, the support frame 5 is reset by the elastic force of the torsion spring.

[0035] A guide cylinder 8 is fixedly installed on the bottom surface of the top pressure frame 7. A guide rod is slidably installed on the inner wall of the guide cylinder 8. A mounting platform 25 is fixedly installed on the bottom surface of the guide rod. At least two guide rods are provided to achieve a sliding connection between the mounting platform 25 and the guide cylinder 8 while maintaining the stability of the sliding of the mounting platform 25.

[0036] The upper surface of the mounting platform 25 is connected to the bottom surface of the guide cylinder 8 through an elastic element. In this embodiment, the elastic element is a common spring, and its elastic force has a tendency to push the mounting platform 25 downward.

[0037] A scraper 22 is fixedly installed on the bottom surface of the mounting platform 25. The bottom surface of the scraper 22 slides against the outer wall of the filter plate 3, and the side wall of the scraper 22 is inclined. The elastic force on the mounting platform 25 keeps the scraper 22 and the filter plate 3 in constant contact. At the same time, the mounting platform 25 can be raised and lowered to accommodate the raising and lowering of the filter plate 3.

[0038] Multiple scraper plates 22 are arranged in a ring. When the top pressure frame 7 reciprocates, it drives the scraper plates 22 to reciprocate synchronously, thereby reciprocating and scraping the filter plate 3.

[0039] During the filtration process, the scraper 22, driven by the top pressure frame 7, reciprocates to scrape the inclined filter plate 3, which can clean the flocs attached to the filter surface in real time, prevent the filter plate 3 from clogging, ensure smooth filtration and stable circulation flow, and maintain the stability of the liquid level and volume in the flocculation tank 1. When discharging sludge, the filter plate 3 slides upward, and the scraper 22, under the action of the elastic element, always sticks to the filter plate 3 and continues to scrape reciprocally. Since the filter plate 3 is inclined, the scraping can push the flocs to move to a lower position, so that the residual flocs are completely scraped off the filter surface and discharged smoothly, achieving complete sludge discharge and self-cleaning.

[0040] In a preferred embodiment of the present invention, a drive motor 6 is fixedly installed on the upper end face of the support frame 5, and a transmission shaft 15 is fixedly installed on the output shaft of the drive motor 6. The drive motor 6 is used to control the rotation of the transmission shaft 15.

[0041] A sector gear 24 is rotatably mounted on the outer wall of the support frame 5, and an annular rack 23 is fixedly mounted on the inner wall of the top pressure frame 7. When the sector gear 24 and the annular rack 23 mesh, the top pressure frame 7 is deflected. When the two are separated, the top pressure frame 7 is reset by elastic force, thereby realizing the reciprocating rotation of the scraping plate 22 and realizing the scraping treatment of the filter plate 3.

[0042] The ring rack 23 meshes with the sector gear 24. The drive shaft 15 controls the rotation of the sector gear 24 through the transmission component. A gear is fixedly installed on the outer wall of the drive shaft 15. A gear that meshes with the gear on the outer wall of the drive shaft 15 is provided at the axial end of the sector gear 24. Thus, when the drive shaft 15 rotates, it drives the sector gear 24 to rotate, which is used to control the deflection of the top pressure frame 7.

[0043] The bottom surface of the support frame 5 is fixedly installed with an installation cylinder 9, and the upper end of the support cylinder 13 is rotatably connected to the bottom surface of the installation cylinder 9. The stability of the rotation of the support cylinder 13 is improved by setting the installation cylinder 9.

[0044] A partition plate 17 is fixedly installed on the inner wall of the mounting cylinder 9. A unidirectional discharge pipe 32 is provided at the bottom of the partition plate 17, wherein the flow direction of the return pipe 26 and the discharge pipe 32 is opposite.

[0045] A control shaft 18 is fixedly installed on the upper end face of the partition plate 17. The bottom of the control shaft 18 passes through the partition plate 17 and is fixedly connected to the inner wall of the support cylinder 13. Thus, when the control shaft 18 rotates, it drives the support cylinder 13 to rotate.

[0046] The upper end of the control shaft 18 is fixedly connected to the axial end of the transmission shaft 15. When the transmission shaft 15 rotates, it drives the control shaft 18 to rotate synchronously.

[0047] A control plug 19 is installed on the radial outer wall of the control shaft 18 through a reciprocating thread engagement. The radial outer wall of the control plug 19 slides against the inner wall of the mounting cylinder 9. The control shaft 18 is a common reciprocating threaded rod that passes through the control plug 19. When the control shaft 18 rotates, it drives the control plug 19 to slide back and forth.

[0048] By controlling the reciprocating sliding of the stopper 19, the air pressure inside the cavity of the mounting cylinder 9 above the partition plate 17 is adjusted, thereby extracting the filtered liquid inside the collection tank 12 and discharging it into the cavity of the flocculation tank 1 through the discharge pipe 32, thus achieving controlled liquid circulation.

[0049] In a preferred embodiment of the present invention, a lifting frame 10 is slidably installed on the outer wall of the mounting cylinder 9. The bottom of the lifting frame 10 is fixedly connected to the outer wall of the guide frame 21. The lifting and sliding lifting frame 10 controls the lifting and sliding of the guide frame 21, thereby controlling the lifting and sliding of the filter plate 3.

[0050] A transmission sleeve 16 is mounted on the radial outer wall of the transmission shaft 15 via a magnetic coupling. When the transmission shaft 15 rotates, the transmission sleeve 16 is rotated by the magnetic coupling.

[0051] The outer wall of the transmission sleeve 16 is fitted with an installation ring 20, and the outer wall of the installation ring 20 is fixedly connected to the outer wall of the lifting frame 10. The outer wall of the transmission sleeve 16 is provided with a spiral groove, and the inner wall of the installation ring 20 is fixedly installed with a ball that slides in cooperation with the spiral groove. When the transmission shaft 15 drives the transmission sleeve 16 to rotate in the forward direction, the installation ring 20 and the lifting frame 10 are controlled to slide downward through the cooperation of the spiral groove and the ball. At this time, the filter plate 3 moves into the inner cavity of the collection tank 12. When the transmission shaft 15 controls the transmission sleeve 16 to rotate in the reverse direction, the installation ring 20 and the lifting frame 10 are controlled to slide upward. At this time, the filter plate 3 slides out of the inner cavity of the collection tank 12.

[0052] The transmission sleeve 16 and the transmission shaft 15 are connected by a magnetic coupling so that the transmission shaft 15 can continue to rotate after the mounting ring 20 moves to the highest and lowest positions.

[0053] An installation box 2 is fixedly installed on the bottom surface of the collection tank 12. A striking pin 27 is elastically installed on the inner wall of the installation box 2. A spring is installed on the outer wall of the striking pin 27. The other end of the spring is fixed to the inner wall of the installation box 2.

[0054] The upper end of the striking pin 27 slides and adheres to the bottom surface of the filter plate 3. When the filter plate 3 is inside the collection tank 12, the upper end of the striking pin 27 adheres to the bottom surface of the filter plate 3. At this time, the striking pin 27 is pulled and then released. The striking pin 27 strikes the bottom of the filter plate 3. The scraper plate 22 can scrape off the flocculent material attached to the surface of the filter plate 3 in real time, avoiding the filter surface blockage from affecting the circulation flow and filtration effect. The impact of the striking pin 27 can shake off the small flocculent material embedded inside the filter plate 3, preventing the filter holes from being blocked and causing a decrease in filtration efficiency. At the same time, the two work together to reduce the residue of flocculent material on the filter plate 3, laying the foundation for subsequent slag discharge operations, further ensuring the continuous and stable operation of the device, and reducing the burden of manual cleaning.

[0055] Multiple tapping pins 27 are provided, and the multiple tapping pins 27 are evenly arranged in a ring along the axis of the collection groove 12. This enables the bottom surface of the filter plate 3 to be tapped in an all-round and uniform manner, avoiding the problem of local filter hole clogging and incomplete cleaning caused by the limited tapping range of a single tapping pin 27. At the same time, the multiple tapping pins 27 evenly distributed in a ring can make the tapping force on the filter plate 3 more balanced, preventing excessive local force from causing deformation and damage to the filter plate 3.

[0056] A control ring 29 is fixedly installed on the inner wall of the return pipe 26. A conical groove is opened on the inner wall of the control ring 29. The conical groove is a through hole. A conical plug 28 is elastically installed on the inner wall of the return pipe 26. The conical plug 28 is used to close the control ring 29. The conical plug 28 is subjected to elastic force, which makes the conical plug 28 tend to close the conical groove, thereby realizing the unidirectional flow of the return pipe 26.

[0057] A connecting plate 30 is fixedly installed on the outer wall of the conical plug 28. When the control plug 19 slides back and forth, the conical plug 28 is controlled to slide back and forth through pressure changes and elastic force, thereby controlling the connecting plate 30 to slide back and forth.

[0058] One end of the connecting plate 30 extends into the inner cavity of the collection tank 12 and is fixedly installed with a top pressing tooth 31. A control tooth 33 is fixedly installed on the outer wall of the striking pin 27. The top pressing tooth 31 is used to press the control tooth 33. During the reciprocating sliding process of the connecting plate 30, it drives the top pressing tooth 31 to reciprocate and slide, pushing the control tooth 33 to slide. Combined with the elastic force received by the striking pin 27, the striking pin 27 strikes the bottom of the filter plate 3.

[0059] like Figure 10 As shown, a method for using an industrial wastewater flocculation treatment device, the method comprising the above-mentioned industrial wastewater flocculation treatment device, includes the following steps: A1. Inject industrial wastewater into flocculation tank 1 and add flocculant, start aeration pipe 11 to aerate, and at the same time drive the drive motor 6 to drive the transmission shaft 15 to rotate, so that the support cylinder 13 rotates in the forward direction. A2. When the support cylinder 13 rotates in the forward direction, the spiral baffle 14 pushes the water to surge upward and overflow into the guide channel 4. The water is then guided into the collection tank 12 through the guide channel 4 and filtered by the filter plate 3. A3. During the filtration process, the scraper plate 22 scrapes the filter plate 3 back and forth, and the top pressing tooth 31 pushes the control tooth 33 to make the striking pin 27 hit the filter plate 3, simultaneously cleaning the filter surface and filter pores of flocs. A4. After processing for a period of time, control the support cylinder 13 to rotate in the opposite direction, stop aeration, and lift the frame 10 to drive the filter plate 3 to slide out and discharge slag. After completion, reset the equipment and enter the next cycle.
