Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a multi-stage industrial wastewater treatment device based on wastewater treatment. Background Technology

[0002] With the acceleration of industrialization, the discharge of industrial wastewater has increased dramatically, posing a serious threat to the environment and ecosystems. Industrial wastewater contains a large number of harmful substances, and if discharged directly without treatment, it will lead to the pollution of surface water, groundwater, and soil, thereby affecting the growth of plants and animals and human health. Therefore, it is particularly important to develop efficient, multi-stage industrial wastewater treatment equipment. Industrial wastewater mainly includes production wastewater and production sewage, which contains industrial production materials, intermediate products, by-products, and pollutants generated during the production process that are lost with the water. In order to effectively deal with the harm of industrial wastewater, it is necessary to develop multi-stage treatment equipment to treat the wastewater step by step in order to meet the discharge standards or realize the recycling of wastewater.

[0003] CN111747607B discloses a wastewater treatment device, including a treatment tank with an inlet pipe and an outlet pipe. A vertical plate is fixedly connected to one side of the top of the treatment tank, and a support mechanism is slidably and liftably installed on the vertical plate. A large number of adsorbent particles are introduced into a rotatable storage bladder. The adsorbent particles are fully diffused into the wastewater in the treatment tank during the rotation of the storage bladder and the stirring shaft. The adsorption layer on the adsorbent particles adsorbs suspended particulate matter in the wastewater. Utilizing the magnetic properties of the adsorbent particles, an electromagnet layer set on the cap-shaped adsorption plate and the bottom surface of the storage bladder facilitates the adsorption of adsorbent particles floating in the wastewater. After the support mechanism lifts the storage bladder together with the cap-shaped adsorption plate upward, it provides convenience for technicians to remove the adsorbent particles without the need for filtration using a filter screen.

[0004] When the above-mentioned existing technology is used for wastewater treatment, it only uses adsorption particles to adsorb suspended impurities in wastewater to achieve the effect of wastewater impurity treatment. However, the method is relatively simple. The single-level wastewater treatment method lacks the pre-filtration and screening process. When the suspended impurities include large particles, it will directly affect the adsorption efficiency of the adsorption particles. Large particles may occupy a large number of sites on the surface of the adsorption particles, causing the adsorption particles to be unable to fully contact and adsorb finer suspended matter, thereby reducing the overall impurity removal effect. Therefore, corresponding improvements are needed.

[0005] CN116808711A discloses a multi-stage sedimentation treatment device for industrial wastewater, including a placement box. A cleaning mechanism is located on the top of the placement box, and a sedimentation mechanism is located on the left side of the placement box. The cleaning mechanism includes a servo motor, which is fixedly connected to the rear right end of the placement box. Wastewater enters the placement box, and the servo motor drives a rotating rod to rotate. This, in turn, rotates a winding wheel and a winding chain, causing a scraper block to slide under the action of a chute, blocking floating objects. The wastewater flows into a central tank, effectively treating the floating objects. A filter screen also filters the wastewater, leaving sediment in a sedimentation tank. Part of the wastewater enters a collection tray through holes, while another part enters a connecting pipe through gaps, and then enters the collection tank through the connecting pipe. This process allows for better sedimentation and filtration of the wastewater, and the device features automatic discharge, making it more convenient to use.

[0006] The aforementioned existing technology only uses a filter screen to filter wastewater, but it is mainly a static filtration process. It usually relies on the gravity or pressure difference of the wastewater to drive the water flow through the filter medium to remove suspended solids. When treating large amounts of wastewater, this method may take a long time to achieve the desired filtration effect. In particular, when treating wastewater containing a large amount of suspended solids, the filtration speed may be significantly reduced. Furthermore, the overall filtration method is singular, only performing filtration and failing to achieve multi-stage treatment of wastewater. Therefore, corresponding improvements are needed. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-stage industrial wastewater treatment device based on wastewater treatment, so as to solve the problem of poor wastewater treatment effect when using the aforementioned multi-stage industrial wastewater treatment device based on wastewater treatment.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage industrial wastewater treatment device based on wastewater treatment, comprising a supporting base, a protective frame, and a clean source box, wherein the top of the supporting base is connected to the clean source box, and the outer side of the clean source box is connected to the protective frame, and the protective frame is fixed to the top of the supporting base.

[0009] Also includes:

[0010] The wastewater treatment tank has a circular water inlet on one side, with a water guide pipe running through it. One end of the water guide pipe is connected to a pump for extracting industrial wastewater. A baffle is fixed on the other side of the wastewater treatment tank. A primary filtration assembly is installed inside the tank. This primary filtration assembly includes a centrifugal filter barrel located inside the tank, with internal support bars evenly connected inside the centrifugal filter barrel. The centrifugal filter barrel is cylindrical, and the internal support bars are arranged in a ring within it. A polytetrafluoroethylene (PTFE) filter membrane is adhered to the wall with adhesive. Two agitation components are installed at the gap between the centrifugal filter bucket and the purification tank. Each agitation component includes a support bearing fixed to one side of the protective frame, with an agitator rod rotatably connected inside the support bearing. A driven roller is fixedly sleeved at one end of the agitator rod near the support bearing. Agitator plates are evenly fixed to the outside of the agitator rod, distributed at both ends of the outer side. A dosing pipe is connected to one side of the purification tank, with one end of the dosing pipe extending into the interior of the purification tank. A through hole is provided on one side of the bottom of the support frame, and a connecting liquid hopper is connected to the through hole. One end of the connecting liquid hopper is connected to a sedimentation tank, and the bottom of the sedimentation tank is connected to a bottom support plate. Support legs are fixed on both sides of the bottom of the bottom support plate. Multiple support columns are connected between the bottom support plate and the purification tank. Support rings are evenly connected around the sedimentation tank, and each support ring is fixed to the top of the bottom support plate. A drain pipe is connected to one side of the bottom of the sedimentation tank, and a drain hopper is connected to the other side of the bottom of the sedimentation tank. A belt synchronous transmission mechanism is provided between the source tank and the sedimentation bottom tank. The belt synchronous transmission mechanism includes a drive motor, which is fixed to the outside of the sedimentation bottom tank by a support plate. One end of the drive motor is fixed to a drive shaft, and one end of the drive shaft extends into the interior of the sedimentation bottom tank. Sewage discharge auger blades are evenly fixed to the outside of the drive shaft. An inner filter cylinder is sleeved on the outside of the drive shaft, and filter holes are evenly provided on the inner filter cylinder. The inner filter cylinder is located inside the sedimentation bottom tank, and both sides of the inner filter cylinder are open.

[0011] Furthermore, one side of the drain hopper is covered with a cellulose membrane, and the cellulose membrane is bonded to the inside of the sedimentation tank by an adhesive.

[0012] Furthermore, both sides of the centrifugal filter bucket are sealed, and a water inlet is opened on the side of the centrifugal filter bucket near the water inlet, and the water inlet is connected to the water inlet.

[0013] Furthermore, there are two driven rollers, distributed on both sides of the support bearing. Both driven rollers are in contact with the outer wall of the centrifugal filter barrel and are in rotational contact with the centrifugal filter barrel. The two driven rollers rotate in opposite directions.

[0014] Furthermore, one end of the active rotating shaft passes through the sedimentation bottom tank and is connected to an active rotating wheel. A driven rotating wheel is connected to the outside of the clean source tank above the active rotating wheel, and a longitudinal transmission belt connects the driven rotating wheel and the active rotating wheel. A driven rotating shaft passes through the inside of the driven rotating wheel, and a fixing frame is fixed at one end of the driven rotating shaft. One end of the fixing frame extends into the centrifugal filter barrel, and the fixing frame is fixedly connected to the centrifugal filter barrel.

[0015] Furthermore, multiple sewage auger blades are provided on the active rotating shaft, and each sewage auger blade is coated with a wear-resistant coating, which is a ceramic coating.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the industrial wastewater multi-stage treatment equipment based on wastewater treatment can perform multi-stage treatment of industrial wastewater to achieve filtration and sedimentation treatment of industrial wastewater, thereby enhancing the wastewater treatment effect;

[0017] By connecting the inlet to the external water pipe, industrial wastewater can be poured into the centrifugal filter tank inside the support frame. Then, the drive motor drives the active shaft and active wheel to rotate, and the driven wheel rotates synchronously with the longitudinal transmission belt, so that the driven shaft and fixed frame rotate, thereby making the centrifugal filter tank rotate synchronously and generating corresponding centrifugal force to achieve effective separation of particulate impurities and dynamic treatment. Compared with traditional static filtration, the wastewater filtration effect is better. The inner wall of the centrifugal filter tank is bonded with a polytetrafluoroethylene filter membrane with adhesive, which can efficiently intercept small particles, colloids, bacteria and other impurities in the wastewater. Under the action of centrifugal force, the wastewater flows through the membrane surface, the impurities are effectively intercepted, and the clean water flows out through the membrane pores, thereby achieving efficient purification of wastewater. This achieves preliminary filtration treatment of industrial wastewater and helps with subsequent sedimentation and purification treatment, so as to realize multi-stage treatment of wastewater and better treatment effect.

[0018] Next, the appropriate hydroxide precipitant is added to the support frame through the dosing pipe to adjust the pH value of the wastewater, so that the heavy metal ions can form hydroxide precipitates that are insoluble in water, effectively removing heavy metals. During this process, the centrifugal filter barrel rotates and contacts the driven roller, generating a certain friction force, which causes the driven roller to rotate synchronously and drive multiple agitator plates to rotate, stirring the wastewater after initial filtration in the centrifugal filter barrel, so that the wastewater and precipitant can fully contact each other, accelerating the sedimentation of suspended particles. By increasing the convection in the liquid, the precipitate can be promoted to reach the sedimentation state quickly, and the problem of clumping and clogging caused by excessive local sedimentation can be prevented.

[0019] During the sedimentation process, the waste liquid flows into the sedimentation tank through the connecting hopper for further sedimentation. The clean liquid after sedimentation is discharged from the drain hopper, which is covered with a cellulose membrane, providing good filtration performance to further remove suspended solids, microorganisms, organic matter, and other impurities from the water, thus helping to optimize water quality. In this process, the drive motor rotates the active shaft, which in turn rotates the sewage auger blades synchronously. During the rotation of the sewage auger blades, the sewage sediment is pushed laterally and discharged from the sewage pipe. The sewage auger blades are coated with a ceramic coating to improve their wear resistance and prevent wear during sewage discharge. Attached Figure Description

[0031] 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] Please see Figures 1-10 The present invention provides the following technical solution: Example

[0033] To address the issue of ineffective wastewater treatment in existing multi-stage industrial wastewater treatment systems, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10A multi-stage industrial wastewater treatment device based on wastewater treatment includes a supporting base 1, a protective frame 2, and a purification tank 3. The top of the supporting base 1 is connected to the purification tank 3, and the outer side of the purification tank 3 is connected to the protective frame 2, which is fixed to the top of the supporting base 1. It also includes: a circular inlet hole 301 on one side of the purification tank 3, with a water guide pipe running through the inlet hole 301. One end of the water guide pipe is connected to a pump for extracting industrial wastewater. A baffle 4 is fixed to the other side of the purification tank 3. A primary filtration assembly is installed inside the purification tank 3, including a centrifugal filter barrel 13 inside the purification tank 3. The centrifugal filter barrel 13 is cylindrical, and the inner support bars 1301 are arranged in a ring within it. A polytetrafluoroethylene (PTFE) filter membrane is bonded to the inner wall of the centrifugal filter barrel 13 with adhesive. The centrifugal filter barrel 13 and the purification tank 3 are connected to the purification tank 3. Two agitation components are provided at the gap position of the box 3. The agitation components include a support bearing 12 fixed to one side of the protective frame 2, and an agitation rod 11 is rotatably connected inside the support bearing 12. A driven roller 1101 is fixedly sleeved at one end of the agitation rod 11 near the support bearing 12. Agitation plates 1102 are evenly fixed on the outside of the agitation rod 11, and the agitation plates 1102 are distributed at both ends of the outside of the agitation rod 11. There are two driven rollers 1101, distributed on both sides of the support bearing 12. Both driven rollers 1101 are in contact with the outer wall of the centrifugal filter barrel 13. The driven rollers 1101 are in rotatable contact with the centrifugal filter barrel 13. The two driven rollers 1101 rotate in opposite directions. A dosing pipe 6 is connected to one side of the purification box 3, and one end of the dosing pipe 6 extends into the interior of the purification box 3. Both sides of the centrifugal filter barrel 13 are sealed. A water outlet is opened on the side of the centrifugal filter barrel 13 near the water inlet 301, and the water outlet and the water inlet 301 are interconnected.

[0034] In this embodiment, the protective frame 2 protects the perimeter of the wastewater treatment tank 3. The tank 3 has a water inlet 301 with a water pipe running through it. One end of the water pipe is connected to a pump for extracting industrial wastewater, allowing the wastewater to be drawn out and injected into the centrifugal filter tank 13 inside the tank 3. A polytetrafluoroethylene (PTFE) filter membrane is bonded to the inner wall of the tank 3 with adhesive. During industrial wastewater treatment, the centrifugal filter tank 13 rotates, generating centrifugal force to effectively separate particulate impurities. Combined with the PTFE filter membrane, it efficiently traps tiny particles, colloids, bacteria, and other impurities in the wastewater, achieving highly efficient wastewater purification. Multiple sets of internal support strips 1301 are evenly fixed within the centrifugal filter tank 13. The centrifugal filter tank 13 is supported to prevent it from shaking or tilting during rotation, thereby improving the stability of the entire equipment. The wastewater after centrifugation is thrown out and falls into the support base 1. Then, an appropriate amount of hydroxide precipitant is injected into the support base 1 through the dosing pipe 6 to adjust the pH value of the wastewater, so that heavy metal ions can form water-insoluble hydroxide precipitates, effectively removing heavy metals. During the rotation of the centrifugal filter tank 13, friction with the driven rollers 1101 causes the two driven rollers 1101 to rotate in opposite directions, which in turn drives multiple agitator plates 1102 to rotate, agitating the thrown-out wastewater and accelerating the contact rate between the precipitant and the wastewater, thereby improving the wastewater treatment efficiency. Example

[0035] This embodiment differs from Embodiment 1 in that it utilizes the belt synchronous transmission mechanism 7 to achieve simultaneous centrifugal treatment and impurity discharge in wastewater treatment. This helps improve wastewater treatment efficiency while achieving energy conservation, environmental protection, and cost savings. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 2 , Figure 3 , Figure 6 , Figure 8 , Figure 9A through hole is provided on one side of the bottom of the support base 1, and a connecting liquid hopper 14 is connected to the through hole. One end of the connecting liquid hopper 14 is connected to the sedimentation tank 8, and the bottom of the sedimentation tank 8 is connected to the bottom support plate 5. Support legs are fixed on both sides of the bottom of the bottom support plate 5. Multiple support columns are connected between the bottom support plate 5 and the purification tank 3. Support rings 801 are evenly connected around the sedimentation tank 8, and the support rings 801 are all fixed to the top of the bottom support plate 5. A drain pipe 10 is connected to one side of the bottom of the sedimentation tank 8, and a drain hopper 9 is connected to the other side of the bottom of the sedimentation tank 8. One side of the drain hopper 9 is covered with a cellulose membrane, and the cellulose membrane is bonded to the inside of the sedimentation tank 8 with adhesive. A belt synchronous transmission mechanism 7 is provided between the purification tank 3 and the sedimentation tank 8. The belt synchronous transmission mechanism 7 includes a drive motor 704, and the drive motor 704 is fixed to the outside of the sedimentation tank 8 by a support plate. One end of the drive motor 704 is fixed to a drive shaft 707, and one end of the drive shaft 707 is fixed to the drive shaft 707. Extending into the interior of the sedimentation tank 8, the active rotating shaft 707 has evenly fixed auger blades 708 on its outer side. An inner filter cylinder 15 is sleeved on the outer side of the active rotating shaft 707, and filter holes are evenly distributed on the inner filter cylinder 15. The inner filter cylinder 15 is located inside the sedimentation tank 8, and both sides of the inner filter cylinder 15 are open. One end of the active rotating shaft 707 passes through the sedimentation tank 8 and is connected to an active rotating wheel 702. A driven rotating wheel 701 is connected to the outer side of the clean water tank 3 above the active rotating wheel 702. A longitudinal transmission belt 703 connects the driven wheel 701 and the driving wheel 702. A driven shaft 705 passes through the driven wheel 701, and a fixing frame 706 is fixed at one end of the driven shaft 705. One end of the fixing frame 706 extends into the centrifugal filter barrel 13. The fixing frame 706 is fixedly connected to the centrifugal filter barrel 13. Multiple sewage discharge auger blades 708 are provided on the driving shaft 707. All sewage discharge auger blades 708 are coated with wear-resistant paint, which is a ceramic coating.

[0036] In this embodiment, wastewater undergoing separation and filtration in the support base 1 undergoes preliminary filtration. Wastewater in contact with the precipitant flows from the connecting hopper 14 into the sedimentation tank 8, where it settles. A drive motor 704 drives the active shaft 707 and active wheel 702 to rotate, which, in conjunction with the longitudinal transmission belt 703, causes the driven wheel 701 to rotate synchronously. This, in turn, rotates the driven shaft 705 and the fixed frame 706, causing the centrifugal filter tank 13 to rotate synchronously, generating centrifugal force and achieving preliminary filtration of the industrial wastewater. Furthermore, the drive motor 704 drives the active shaft 707 to rotate, causing the discharge auger 708 to rotate, thus discharging the wastewater that has fallen into the sedimentation tank 8 from the discharge hopper 9. A cellulose membrane is bonded to the hopper 9 with an adhesive, providing good filtration performance. This further removes suspended solids, microorganisms, organic matter, and other impurities from the water, helping to optimize water quality. The rotating active shaft 707 and the auger blades 708 discharge the sedimented impurities from the wastewater through the drain pipe 10, achieving effective impurity removal. An inner filter cylinder 15 is installed in the sedimentation tank 8, allowing the pre-treated wastewater to undergo further refinement as it flows through the sedimentation tank 8. This enables multi-stage and multi-mode purification of the wastewater. The entire operation can be driven by a single drive motor 704, effectively saving operating costs and simplifying subsequent maintenance procedures, thus optimizing the wastewater treatment process.
