Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment and reuse device for chemical production. Background Technology

[0002] In the treatment and reuse of wastewater from chemical production, electrochemical treatment relies on the basic principles of electrochemistry. In a specially designed electrochemical reactor, pollutants in chemical wastewater are degraded and separated through electrode reactions and derived physical and chemical effects. It is also a commonly used pretreatment unit in the chemical wastewater reuse process, laying the water quality foundation for wastewater reuse.

[0003] For example, patent CN209226743U discloses a wastewater treatment device for chemical production. This patent is equipped with a flocculent particle filter box for electrolytic filtration, which can electrically separate flocculent particles in wastewater. Based on the principle of attraction between opposite charges, the particles are separated on the outside of the adhesion net, achieving effective filtration. However, in actual use, because the two electrodes are fixed in position and are in a static state, the single inlet causes uneven electrode reactions in the reactor. Electrodes closer to the inlet wear out quickly or suffer from severe scaling, while the reactions on the side farther from the inlet are insufficient, resulting in unstable treatment effects.

[0008] Furthermore, a connecting component is provided at one end of the central shaft, and the connecting component includes a fixed seat. The fixed seat is placed at one end of the central shaft, and an elastic clip is provided on one side of the fixed seat. A handle is abutted at the top of the elastic clip, and a cam is fixed at one end of the handle. A pulley seat is provided on one side of the cam, and a return spring is abutted on one side of the pulley seat. A pressure rod is provided inside the return spring, and a support plate is fixed on the outside of the pressure rod. A clamping ring is placed on the outside of the support plate, and a locking pin is fixed on one side of the clamping ring. A locking groove is symmetrically opened in the middle of one side of the frame, and a pin is fixed at one end of the frame, and a pin hole is opened at the other end of the frame.

[0009] Furthermore, the cam is rotatably connected to the fixed base, and the cam is fan-shaped.

[0010] Furthermore, the pressure rod is fixedly connected to the pulley seat, and the axis of the pressure rod coincides with the axis of the central shaft.

[0011] Furthermore, the return spring abuts against the central shaft, and the central shaft is slidably connected to the support plate, and the support plate is equidistantly distributed along the length of the pressure rod.

[0012] Furthermore, a guide component is provided on the outer side of the frame, and the guide component includes a connecting cover. The connecting cover is fixed on one side of the frame, and the connecting cover is rotatably connected to a guide plate via a torsion spring shaft, and the guide plate abuts against the iron plate.

[0013] Furthermore, a switching assembly is installed on one side of the upper shell, and the switching assembly includes a fixed box. The fixed box is fixed on one side of the upper shell, and coil sleeves are symmetrically arranged at both ends of the fixed box. An iron core is fixed inside the coil sleeves. A rack is slidably connected inside the fixed box, and permanent magnets are symmetrically arranged at both ends of the rack. Buffer blocks are provided on both sides of the permanent magnets. A synchronous gear meshes with the top of the permanent magnets, and a coupling is installed inside the synchronous gear. Air cylinders are equidistantly arranged on one side of the coupling, and a piston rod is slidably connected inside the air cylinders.

[0014] Furthermore, the piston rod is fixedly connected to the scraper, and the width of the scraper is greater than the width of the guide plate.

[0015] This invention provides a wastewater treatment and reuse device for chemical production, which has the following beneficial effects: 1. This invention uses an external pump to pump pre-filtered wastewater into the lower casing via a diversion pipe. The water flow impacts the impeller shaft blades, driving its rotation. The central shaft then rotates via a drive gear and a driven gear, causing the electrode plate to rotate continuously in the wastewater. This solves the problem of uneven reaction in traditional fixed electrodes, significantly extending the overall lifespan of the electrodes. Furthermore, the electrode plate's rotation power comes directly from the water flow, eliminating the need for an additional rotating motor, reducer, and control power supply system, greatly reducing equipment operating costs. The gear reduction mechanism effectively prevents jamming, while the slip rings and embedded cables ensure continuous power supply to the iron plate during rotation. In addition, the cathode surface on the rotating iron plate continuously scrapes against the fixed scraper, continuously removing the generated soft scale and preventing its accumulation and thickening, which would reduce the electrode's active area, increase reaction resistance, and decrease treatment efficiency.

[0016] 2. The replacement operation of the iron plate after wear and tear of this invention is simple and efficient, without complicated procedures. Through the cooperation of components such as handles and elastic clips, the clamping ring and frame can be quickly separated and clamped, thereby completing the disassembly and installation of the iron plate. During the installation process, the frame can be accurately positioned through the joint, pin, and pin hole. The rubber ring on the side of the clamping ring can evenly distribute the clamping force, preventing over-pressure damage to the components and improving the clamping seal. This replacement structure can fix all frames at the same time, eliminating the need to operate on individual iron plates one by one, greatly reducing the operation steps and time of plate replacement, effectively improving replacement efficiency and reducing labor costs.

[0017] 3. This invention forms a stable series circuit through the cooperation of positive and negative power cables, coil sleeve, slip ring, slot, and connector. The coil sleeve contains an iron core, which generates magnetic force when powered. This, along with a permanent magnet, enables precise positioning of the rack, ensuring that the scraper is in close contact with the negative surface of the iron plate, thus guaranteeing effective cleaning. When the power polarity needs to be switched, the magnetic field direction changes accordingly, causing the rack to slide. The buffer block effectively reduces collision losses during rack sliding, extending the service life of the mechanism. Simultaneously, the rack drives the scraper to rotate, allowing the scraper to quickly contact the negative surface of the iron plate after the change. This achieves synchronous automation of polarity switching and scraper adjustment, eliminating the need for manual intervention, avoiding cleaning omissions, and saving labor costs. Furthermore, as the thickness of the iron plate decreases with long-term use, the compressed air in the air cylinder can push the piston rod to adjust the scraper position, ensuring the scraper's contact with the iron plate and guaranteeing effective cleaning. The guide plate remains in contact with the surface of the iron plate even as its thickness decreases, guiding the scraper smoothly to the edge, preventing scraper impact, jamming, or damage, and ensuring long-term smooth and reliable operation of the cleaning mechanism.

[0020] Please see Figures 1 to 5The present invention provides a technical solution: a chemical production wastewater treatment and reuse device, comprising a lower shell 1 and an electrolysis assembly 6. An upper shell 2 is mounted on the top of the lower shell 1, and a diversion pipe 3 is provided on one side of the upper shell 2. A collecting pipe 4 is connected to the other side of the upper shell 2, and a filter 5 is fixed on one side of the collecting pipe 4. The electrolysis assembly 6 is located at the upper center of the lower shell 1, and the electrolysis assembly 6 includes a side shell 601. An impeller shaft 602 is rotatably connected inside the side shell 601, and a drive gear 603 is fixed to one end of the impeller shaft 602. A driven gear 604 meshes with one side of the drive gear 603. The central shaft 605 is installed in the part, and electric slip rings 606 are sleeved at both ends of the central shaft 605. The central shaft 605 is rotatably connected to the lower shell 1 and the upper shell 2 respectively through shaft seals, and the lower shell 1 is fixedly connected to the side shell 601. A frame 607 is provided on the outer side of the middle part of the central shaft 605, and an iron plate 608 is fixed inside the frame 607. A slot 609 is opened on the outer periphery of the central shaft 605, and a connector 610 is inserted into the slot 609. A scraper 611 abuts against one side of the iron plate 608. The outer shell of the connector 610 is fixedly connected to the frame 607, and the contact piece inside the connector 610 is fixedly connected to the iron plate 608. The specific operation is as follows: the external pump body will input the pre-filtered sewage into the lower shell 1 through the diversion pipe 3. During this process, the water flow will pass through one of the inner cavities of the side shell 601, thereby impacting the blades on the impeller shaft 602 and driving it to rotate. This, in turn, drives the central shaft 605 to rotate through the driving gear 603 and the driven gear 604. Therefore, when the sewage flows through the space between the iron plates 608 towards the collection pipe 4, the central shaft 605 will drive the iron plates 608 to rotate. This allows different parts of the iron plates 608 to circulate through high and low flow velocity zones and near and far inlet areas, solving the uneven problem of "overload at the near end and idle at the far end" caused by the fixed position of traditional fixed electrodes. This makes the electrochemical corrosion and scaling of the electrodes more uniform on a macroscopic scale, greatly extending the overall service life of the electrodes and ensuring the spatial stability of the electric field and reaction intensity in the reactor. This improves the treatment effect and consistency of the effluent quality. At the same time, the self-rotation power of the plates comes from the water flow itself, eliminating the need for an additional rotating motor, reducer, and supporting control system. The electrical system helps reduce equipment operating costs. Meanwhile, the reduction mechanism formed by the driving gear 603 and driven gear 604 reduces the drive load and prevents jamming. Furthermore, the electric slip ring 606, the pre-embedded cables in the central shaft 605, the slots 609, and the connectors 610 supply power to the rotating iron plates 608 at both ends, ensuring they continuously function as electrodes during rotation. The middle iron plate 608 is not directly connected to an external power source; it participates in the reaction as a bipolar plate in the electric field. The cathode surface of the rotating iron plate 608 continuously scrapes against the fixed scraper 611, continuously removing soft scale such as hydroxides, carbonates, or deposits, preventing their accumulation and thickening that would reduce the electrode active area and increase reaction resistance. The scraper 611 is close to the collection pipe 4, allowing the scraped impurities to be carried away by the flowing wastewater and enter the downstream filter 5 through the collection pipe 4. This achieves "reaction and cleaning simultaneously," maintaining the electrochemical activity of the electrode surface and avoiding the reduction in treatment efficiency caused by scaling.

[0021] Please see Figure 5 and Figure 6A connecting component 7 is provided at one end of the central shaft 605, and the connecting component 7 includes a fixed seat 701. The fixed seat 701 is mounted at one end of the central shaft 605, and an elastic clip 702 is provided on one side of the fixed seat 701. The top of the elastic clip 702 abuts against a handle 703, and a cam 704 is fixed at one end of the handle 703. A pulley seat 705 is provided on one side of the cam 704, and a return spring 706 abuts against one side of the pulley seat 705. The cam 704 is rotatably connected to the fixed seat 701, and the cam 704 is fan-shaped. A pressure rod 707 is provided inside the return spring 706, and the outer surface of the pressure rod 707... A support plate 708 is fixed to the side, a pressure rod 707 is fixedly connected to a pulley seat 705, and the axis of the pressure rod 707 coincides with the axis of the central shaft 605. A return spring 706 abuts against the central shaft 605, and the central shaft 605 is slidably connected to the support plate 708. The support plate 708 is evenly distributed along the length of the pressure rod 707. A clamping ring 709 is placed on the outer side of the support plate 708, and a locking pin 710 is fixed on one side of the clamping ring 709. A locking groove 711 is symmetrically opened in the middle of one side of the frame 607, and a pin pin 712 is fixed at one end of the frame 607, and a pin hole 713 is opened at the other end of the frame 607. The specific operation is as follows: When the iron plate 608 needs to be replaced due to wear and tear after long-term use, simply pull the handle 703 forcefully to separate it from the elastic clip 702. This will also cause the cam 704 to rotate, moving its protrusion away from the pulley seat 705. The return spring 706, supported by the groove at the end of the central shaft 605, will push the pulley seat 705 into contact with the cam 704. This, along with the pressure rod 707 and the support plate 708, will cause the clamping ring 709 to separate from the outer side of the frame 607. At this point, the iron plate 608 can be disassembled and replaced. During installation, first insert the connector 610 on the frame 607 into the slot 609, then install the two adjacent frame plates 607... The pins 712 and 713 are used for initial positioning between the 07 and 607. Then, by rotating the handle 703 in the opposite direction, the cam 704's protrusion presses against the pulley seat 705, causing the locking pin 710 to insert into the slot 711. This, in turn, drives the clamping ring 709 to clamp the frame 607 through the pressure rod 707 and the support plate 708. At the same time, the rubber ring on the side of the clamping ring 709 evenly distributes the clamping force and prevents overpressure. Thus, all the frames 607 can be fixed at the same time during operation, which helps to improve the efficiency of plate replacement. Furthermore, the clamping ring 709 is slidably connected to the central shaft 605 through a seal, which can block the opening on the outside of the central shaft 605 to prevent sewage leakage.

[0022] Please see Figure 5 and Figure 7A guide assembly 8 is provided on the outer side of the frame 607, and the guide assembly 8 includes a connecting cover 801. The connecting cover 801 is fixed to one side of the frame 607, and the connecting cover 801 is rotatably connected to a guide plate 802 via a torsion spring shaft. The guide plate 802 abuts against the iron plate 608. A switching assembly 9 is arranged on one side of the upper shell 2, and the switching assembly 9 includes a fixing box 901. The fixing box 901 is fixed to one side of the upper shell 2, and coil sleeves 902 are symmetrically arranged at both ends of the fixing box 901. An iron core 90 is fixed inside the coil sleeve 902. 3. A rack 904 is slidably connected inside the fixed box 901, and permanent magnets 905 are symmetrically arranged at both ends of the rack 904. Buffer blocks 906 are provided on both sides of the permanent magnets 905. A synchronous gear 907 is meshed on the top of the permanent magnets 905. A coupling shaft 908 is arranged inside the synchronous gear 907. An air cylinder 909 is equidistantly arranged on one side of the coupling shaft 908. A piston rod 910 is slidably connected inside the air cylinder 909. The piston rod 910 is fixedly connected to the scraper 611, and the width of the scraper 611 is greater than the width of the guide plate 802. The specific operation is as follows: Since the positive and negative power cables are connected to the coil sleeves 902 on both sides respectively, and form a series circuit with the corresponding iron plate 608 via the slip ring 606, slot 609, connector 610, and coil sleeve 902, and the iron core 903 is installed inside the coil sleeve 902, during power supply, the iron core 903 inside the coil sleeve 902 will generate a large magnetic force to attract the permanent magnet 905. Simultaneously, the coil sleeve 902 at the other end of the rack 904 and the permanent magnet 905 repel each other, thus positioning the rack 904 and allowing the scraper to move. Plate 611 and the negative electrode surface of iron plate 608 are in contact. When the power polarity needs to be switched after a period of use, the direction of the magnetic field formed by coil sleeve 902 and iron core 903 will also be changed at the same time as the positive and negative electrodes are reversed. Under the action of permanent magnet 905, rack 904 will be driven to slide to the other end of fixed box 901. At this time, buffer block 906 plays a buffering role between rack 904 and inner wall of fixed box 901 to reduce collision loss. Rack 904 will then be driven by synchronous gear 907 and coupling shaft 908. The scraper 611 rotates half a turn, bringing it into contact with the negative electrode surface of the iron plate 608 after the polarity switch. This achieves complete synchronization and automation of polarity switching and scraper 611 adjustment, requiring no manual intervention or additional sensors, ensuring that no cleaning action is missed. Simultaneously, as the thickness of the iron plate 608 gradually decreases during the polarity switching process, the compressed air stored inside the air cylinder 909 pushes the piston rod 910, thereby improving the adhesion between the scraper 611 and the surface of the iron plate 608. The air cylinder 909... The end cap also limits the extension distance of the piston rod 910, preventing it from slipping completely. Furthermore, the guide plate 802, under the action of the torsion spring shaft, keeps its end in contact with the thinner iron plate 608. Therefore, when the scraper 611 moves from the surface of the iron plate 608 to the frame 607, it can smoothly guide the scraper 611 to transition, effectively preventing the scraper 611 from being impacted, stuck, or damaged due to suddenly falling into the step groove between the iron plate 608 and the frame 607, thus ensuring the smooth and reliable long-term operation of the mechanism.

[0023] In summary, this type of chemical production wastewater treatment and reuse device is used as follows: First, the external pump body draws the pre-filtered wastewater into the lower casing 1 through the diversion pipe 3. During this process, the water flows through one of the inner cavities of the side casing 601, impacting the blades on the impeller shaft 602 and driving it to rotate. This, in turn, drives the central shaft 605 to rotate via the driving gear 603 and the driven gear 604. Therefore, when the wastewater flows through the space between the iron plates 608 towards the collection pipe 4, the central shaft 605 drives the iron plates 608 to rotate. This causes different parts of the iron plates 608 to circulate through high and low flow velocity zones and near and far inlet areas, resulting in electrochemical corrosion and scaling of the electrodes. The process becomes more uniform on a macroscopic scale, greatly extending the overall service life of the electrodes and improving the treatment effect and consistency of the effluent water quality. At the same time, the rotation power of the electrode plates comes from the water flow itself, eliminating the need for additional rotating motors, reducers, and supporting control and power supply systems, which helps reduce equipment operating costs. Furthermore, the electric slip ring 606, the pre-embedded cables in the central shaft 605, the slots 609, and the connectors 610 provide power to the iron plates 608 at both ends during rotation, ensuring that they continue to work as electrodes during rotation. The middle iron plate 608 is not directly connected to the external power supply and participates in the reaction as a bipolar plate in the electric field. Next, since the positive and negative power cables are connected to the coil sleeves 902 on both sides respectively, and form a series circuit with the corresponding iron plate 608 through the slip ring 606, slot 609, connector 610, and coil sleeve 902, and the iron core 903 is installed inside the coil sleeve 902, during the power supply process, the iron core 903 inside the coil sleeve 902 will generate a large magnetic force to attract the permanent magnet 905. At the same time, the coil sleeve 902 and the permanent magnet 905 at the other end of the rack 904 repel each other, which can position the rack 904 so that the scraper 611 and the negative pole surface of the iron plate 608 are aligned. The contact between the rotating iron plate 608 and the fixed scraper 611 allows the cathode surface to be continuously scraped against each other, which can continuously remove the generated soft scale, such as hydroxide, carbonate scale or attachments, preventing it from accumulating and thickening, which would reduce the electrode active area and increase the reaction resistance. In addition, the scraper 611 is close to the collection pipe 4, so that the scraped impurities are carried away by the flowing sewage in time and enter the downstream filter 5 through the collection pipe 4. This achieves "reaction and cleaning at the same time", maintaining the electrochemical activity of the electrode surface for a long time and avoiding the decline in treatment efficiency due to scaling. Then, when the power polarity needs to be switched after a period of use, the direction of the magnetic field formed by the coil sleeve 902 and the iron core 903 is changed at the same time as the positive and negative poles of the plates are reversed. Under the action of the permanent magnet 905, the rack 904 is driven to slide towards the other end of the fixed box 901. At this time, the buffer block 906 acts as a buffer between the rack 904 and the inner wall of the fixed box 901 to reduce collision loss. The rack 904 will then drive the scraper 611 to rotate half a turn through the synchronous gear 907 and the connecting shaft 908, so that it is in contact with the negative pole surface of the iron plate 608 after the change. This achieves complete synchronization and automation of polarity switching and scraper 611 adjustment, without manual intervention or additional sensors, ensuring cleanliness. The action is never missed. At the same time, as the thickness of the iron plate 608 gradually decreases during the switching of positive and negative poles, the compressed air stored inside the air cylinder 909 pushes the piston rod 910, thereby improving the fit between the scraper 611 and the surface of the iron plate 608. Furthermore, under the action of the torsion spring shaft, the guide plate 802 keeps its end in contact with the thinner iron plate 608. Therefore, when the scraper 611 moves from the surface of the iron plate 608 to the frame 607, it can be smoothly guided to transition. This effectively prevents the scraper 611 from being impacted, stuck, or damaged due to suddenly falling into the step groove between the iron plate 608 and the frame 607, ensuring the smooth and reliable operation of the mechanism over a long period of time. Finally, when the iron plate 608 needs to be replaced due to wear and tear after prolonged use, simply pull the handle 703 forcefully to separate it from the elastic clip 702. This will also cause the cam 704 to rotate, moving its protrusion away from the pulley seat 705. The return spring 706, supported by the groove at the end of the central shaft 605, will then push the pulley seat 705 into contact with the cam 704. This, along with the pressure rod 707 and the support plate 708, will cause the clamping ring 709 to separate from the outer side of the frame 607. At this point, the iron plate 608 can be disassembled and replaced. During installation, first remove the clips from the frame 607... The connector 610 is inserted into the slot 609. Then, the two adjacent frame pieces 607 are initially positioned by the pin 712 and the pin hole 713. Then, the handle 703 is rotated in the opposite direction, which drives the convex part of the cam 704 to press the pulley seat 705, so that the locking pin 710 is inserted into the locking groove 711. Then, the pressure rod 707 and the support plate 708 drive the clamping ring 709 to clamp the frame piece 607. At the same time, the rubber ring on the side of the clamping ring 709 evenly distributes the clamping force and prevents overpressure. Thus, all the frames 607 can be fixed at the same time during operation, which helps to improve the efficiency of plate replacement.
