Description

Technical Field

[0001] The present invention relates to the technical field of medical sewage treatment, in particular to a boron-doped diamond electrode medical sewage treatment device. Background Art

[0002] Boron-doped diamond electrodes can be used for electrochemical treatment of wastewater. They have high oxidation ability and can decompose organic matter and kill pathogens. Medical wastewater may contain complex components such as drug residues, bacteria, and viruses, which require high efficiency and stability to treat. Therefore, compared with traditional electrodes, boron-doped diamond electrodes (BDD) have many advantages such as wide window, small background current, good electrochemical stability, good mechanical properties, strong corrosion resistance, and good conductivity. They have good prospects in the field of electrochemical oxidation treatment of medical wastewater.

[0003] The existing patent application, with publication number CN220182895U and publication date December 15, 2023, is titled "A Continuous Flow Wastewater Treatment Device Using Boron-Doped Diamond Electrodes." The patent includes a wastewater treatment chamber, electrodes, and an agitator. The electrodes comprise a first boron-doped diamond anode, a first cathode, a second boron-doped diamond anode, and a second cathode, arranged in sequence. The agitator comprises a stirring shaft, a first stirring blade, and a second stirring blade. The stirring shaft and the first stirring blade connected to the stirring shaft are positioned between the first cathode and the second boron-doped diamond anode. The second stirring blade comprises a blade portion and a connecting portion connecting the stirring shaft and the blade portion. When the second stirring blade rotates near the first cathode, the blade portion is positioned between the first boron-doped diamond anode and the first cathode. When the second stirring blade rotates near the second boron-doped diamond anode, the blade portion is positioned between the second boron-doped diamond anode and the second cathode. This device is well-suited for continuous flow treatment, achieving excellent wastewater treatment results while reducing the footprint of the treatment equipment.

[0004] The above application has its shortcomings. Although the continuity of the treatment process can be improved by adding an agitator, the surface of the electrode is still easily covered with pollutants to form a passivation layer during long-term operation, resulting in a decrease in current efficiency. Secondly, the traditional fixed plate structure is prone to cause water short-circuiting and low organic mass transfer efficiency. Moreover, the filtration unit and the electrode system are set independently, and the accumulation of suspended matter can easily cause blockage between the plates, requiring frequent shutdowns for cleaning, which will also affect the continuity of the treatment.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] See also Figure 1-8, a boron-doped diamond electrode medical sewage treatment device provided by an embodiment of the present invention includes a sewage treatment chamber 1, and also includes a movable filter plate 2, which is elastically installed inside the sewage treatment chamber 1, and a plurality of anode plates 3 and cathode plates 4 horizontally and alternately distributed are inserted above the movable filter plate 2 inside the sewage treatment chamber 1, a movable bracket 5 is installed in the sewage treatment chamber 1, and the two ends of the movable bracket 5 are respectively abutted with the top surface of the movable filter plate 2, and a cleaning and capturing component 6 and a spoiler component 7 are installed on the top of the movable bracket 5 between adjacent anode plates 3 and cathode plates 4, a pair of combing frames 8, which are slidably installed on the capturing and cleaning components, and the bottom of the combing frame 8 overlaps the top surface of the movable filter plate 2. When the movable bracket 5 moves, it drives the spoiler component 7 to rotate. When the movable bracket 5 presses the movable filter plate 2 to make it descend, the spoiler component 7 abuts and cooperates with the combing frame 8, so that the combing frame 8 can be lifted and lowered reciprocally on the cleaning and capturing component 6.

[0033] Specifically, the movable filter plate 2 is installed in the sewage treatment chamber 1 by an elastic member, and a water inlet is provided at the bottom of one side of the sewage treatment chamber 1, and a water outlet is provided at the top of one side. A certain distance is reserved between the initial position of the movable filter plate 2 and the anode plate 3. The movable filter plate 2 can move downward after being pressurized, and the anode plate 3 and the cathode plate 4 are alternately inserted horizontally in the sewage treatment chamber 1. The surface of the plate is coated with a boron-doped diamond coating. There is a channel between the anode plate 3 and the cathode plate 4 for sewage to flow through, which is used to guide the flow direction of sewage. The movable bracket 5 can be driven by a driving source to reciprocate back and forth in the sewage treatment chamber 1, and its two ends can contact the top of the movable filter plate 2. When it moves to one side of the sewage treatment chamber 1, it can force the movable filter plate 2 to drop rapidly. After the sewage enters the sewage treatment chamber 1, it is first filtered by the movable filter plate 2 to remove large particles of impurities, and then enters the electrochemical reaction zone above the movable filter plate 2 for treatment. After continuous operation, the cleaning and collection component 6 can be driven to scrape by the movable bracket 5 moving back and forth. In addition to removing dirt from the surface of the electrode plates, it also captures and adsorbs charged pollutants between the anode plate 3 and the cathode plate 4. The spoiler component 7 can also rotate and stir the sewage between the anode plate 3 and the cathode plate 4 when the movable support 5 moves, so that the sewage forms turbulence between the plates, and the organic matter mass transfer rate is improved compared with the traditional device. At the same time, dynamic filtration and anti-blocking are combined. When the movable support 5 presses the movable filter plate 2 to the lowest point, the pressure under the movable filter plate 2 increases sharply, forcing part of the sewage to quickly penetrate the filter holes. When the movable filter plate 2 rebounds, a negative pressure suction effect is generated to peel off the particles attached to the filter holes, so that the filter plate flux is restored. In addition, each time the movable filter plate 2 descends and rebounds, the combing frame 8 also completes a lifting action. When the movable filter plate 2 continues to descend under the pressure of the moving support 5, the combing frame 8 with the bottom resting on the movable filter plate 2 will move down and be intermittently pushed by the spoiler component 7 to quickly sort out the debris on the cleaning and collection component 6, thereby ensuring the subsequent cleaning effect of the cleaning and collection component 6 on the electrode plates.

[0034] Compared with the prior art, the embodiment of the present invention integrates the cleaning and capturing component 6 and the spoiler component 7 in the electrode array through the linkage design of the elastic movable filter plate 2 and the movable support frame 5, thereby realizing the synergistic effect of mechanical stripping and electrolytic oxidation of the electrode plate pollutants. When the device is in operation, the movable filter plate 2 filters the sewage entering the electrode area. When the movable support frame 5 drives the cleaning and capturing component 6 to move between the anode plate 3 and the cathode plate 4, the cleaning and capturing component 6 adsorbs the impurities in the area it passes through and cleans the surface of the electrode plate. The spoiler component 7 can also change the flow direction of the sewage in the area it passes through, thereby improving the mass transfer efficiency of organic matter. At the same time, when the elastic filter plate is pressed down rapidly by the movable support frame 5, the force it receives can accelerate the reciprocating penetration of sewage above and below the elastic filter plate, thereby avoiding clogging of the filter pores and affecting the sewage treatment efficiency. At the same time, the combing frame 8 can be driven by the spoiler component 7 to intermittently move the cleaning and capturing component 6 after the elastic filter plate descends, thereby reducing the number of required maintenance processes.

[0035] In a further embodiment of the present invention, a pair of adjusting screws 11 with threads passing through the movable bracket 5 are installed in the sewage treatment chamber 1, and a driving motor 12 connected to the adjusting screw 11 is fixedly connected to the outside of the sewage treatment chamber 1. Specifically, the driving motor 12 drives the movable bracket 5 to move back and forth in the sewage treatment chamber 1 through the adjusting screw 11, and its movement speed can be adjusted steplessly. In low-speed mode, the cleaning and capturing component 6 deeply scrapes the surfaces of the anode plate 3 and cathode plate 4 it contacts. In high-speed mode, the cleaning and capturing component 6 scrapes quickly, and the spoiler component 7 rotates when the movable bracket 5 translates, and the rotation speed increases synchronously with the moving speed of the movable bracket 5, so as to form a high-intensity eddy current field between the anode plate 3 and the cathode plate 4, thereby improving the efficiency of sewage treatment.

[0036] In a further embodiment of the present invention, both ends of the movable bracket 5 are vertically mounted with abutment columns 51, both sides of the top of the movable filter plate 2 are symmetrically mounted with wedge-shaped abutment plates 21, and both sides of the bottom of the movable filter plate 2 are fixedly connected with top springs 22, and the bottom of the top spring 22 is fixed to the inner wall of the sewage treatment chamber 1. Specifically, the stroke position of the movable bracket 5 is dynamically related to the downward pressure amplitude of the movable filter plate 2. When the movable bracket 5 moves horizontally, if the abutment column 51 slides along the inclined surface of the wedge-shaped abutment plate 21, the horizontal displacement will be converted into vertical downward force, forcing the movable filter plate 2 The compression top spring 22 moves downward. During the downward pressure process, the top spring 22 stores energy and generates high-frequency micro-vibration, which increases the shedding rate of suspended matter in the filter plate pores. When the abutment column 51 breaks away from the wedge-shaped slope, the top spring 22 releases energy to push the movable filter plate 2 to reset. When the movable filter plate 2 rebounds, a negative pressure suction effect is generated to peel off the particulate matter attached to the filter holes. At the same time, a secondary oscillation is formed through the buffering of the limit block, which further strengthens the reciprocating infiltration of sewage and can quickly press down the movable filter plate 2 to clean up the debris blocked in the filter holes. There is no need to frequently maintain the movable filter plate 2.

[0037] In a further embodiment of the present invention, the cleaning and capturing assembly 6 includes a capturing filter 61 plugged and fixed to the top of the movable support frame 5, and cleaning brushes 62 in contact with the anode plate 3 and the cathode plate 4 are vertically installed on both sides of the capturing filter 61. Specifically, when the movable support frame 5 drives the cleaning and capturing assembly 6 to move horizontally, the cleaning brushes 62 on both sides scrape the surfaces of the anode plate 3 and the cathode plate 4 in a sliding contact manner, so that the bristles of the cleaning brush 62 can absorb or clean the debris attached to the plates, and the capturing filter 61 then intercepts the pollutants that fall off between adjacent plates, thereby achieving multiple high-efficiency impurity removal and accelerating the decomposition rate of organic matter.

[0038] In a further embodiment of the present invention, the spoiler assembly 7 includes a rotating shaft 71 rotatably mounted on the bottom of the capture filter 61, an impeller 72 is installed on the rotating shaft 71, a transmission shaft 73 is rotatably mounted in the movable bracket 5, a pair of transmission belts 74 are installed between the transmission shaft 73 and each rotating shaft 71, and friction transmission is carried out between the anode plate 3 and the cathode plate 4 and the transmission shaft 73. Specifically, when the movable bracket 5 drives the transmission shaft 73 to move, since the transmission shaft 73 is always in contact with the electrode plate, the bottom of the anode plate 3 and the cathode plate 4 can be in contact with the transmission shaft 73. The silicone layer of the moving shaft 73 generates rolling friction, driving the transmission shaft 73 to rotate when the moving bracket 5 translates, and then drives the rotating shaft 71 to rotate through the transmission belt 74, so that the impeller 72 generates a reverse vortex between the anode plate 3 and the cathode plate 4, effectively breaking up the biofilm and improving the mass transfer efficiency of organic matter, while increasing the stripping rate of sediment on the surface of the plate, realizing the adaptive coordination of water flow power and mechanical cleaning, so that the cleaning brush 62 can quickly and efficiently clean the dirt on the surface of the plate in coordination with the changes in water flow, reducing the impact of impurities on sewage treatment.

[0039] In a further embodiment of the present invention, a plurality of limiting grooves 54 matching the anode plate 3 and the cathode plate 4 are provided on the top of the movable support 5, and a plurality of anti-slip collars 75 are fixedly provided on the transmission shaft 73. The anode plate 3 and the cathode plate 4 are respectively in contact with the surface of each anti-slip collar 75, and the anti-slip collar 75 is located in the limiting groove 54. Specifically, the limiting groove 54 is U-shaped with the notch facing upward. When the electrode plate is inserted into the sewage treatment chamber 1, the limiting groove 54 can play a positioning role, and when the bottom of the anode plate 3 and the cathode plate 4 enter the corresponding After the limit groove 54 is reached, the anode plate 3 and the cathode plate 4 are constrained in a fixed position in the limit groove 54, and their bottoms continue to squeeze the surface of the anti-slip ring 75, driving the transmission shaft 73 to rotate at a constant speed during the translation process through friction. The anti-slip ring 75 produces elastic deformation under the action of contact pressure, forming an adaptive contact surface to ensure transmission efficiency. When the transmission shaft 73 rotates, it is linked to the impeller 72 through the transmission belt 74 to form spiral turbulence in the sewage, accelerating the flow speed of sewage between the anode plate 3 and the cathode plate 4, and improving the treatment effect.

[0040] In a further embodiment of the present invention, combing teeth 81 are symmetrically installed on one side of the combing frame 8, and the cleaning brush 62 is located between a pair of combing teeth 81. The other side of the combing frame 8 is fixedly connected to an abutment frame 82, which is located above the rotating shaft 71. The rotating shaft 71 is fixedly connected with an abutment protrusion 76 that cooperates with the abutment frame 82. Specifically, since the combing frame 8 is placed on the top surface of the movable filter plate 2, the movable filter plate 2 rises and falls with the movable filter plate 2. When the movable abutment frame 5 moves back a distance, it can continue to move back to press the movable filter plate 2 by pressing the wedge-shaped abutment plate 21. At this time, the combing frame 8 The combing frame 8 will also descend so that the height of the abutment frame 82 can contact the abutment protrusion 76. When the rotating shaft 71 drives the abutment protrusion 76 to rotate, the abutment protrusion 76 periodically hits the abutment frame 82, forcing the entire combing frame 8 to lift upward. After the protrusion is out of contact, the combing frame 8 automatically descends and resets under gravity. In this process, the comb teeth penetrate the gaps between the bristles of the cleaning brush 62 to peel off entangled or attached pollutants. At the same time, when the combing frame 8 descends, it hits the movable filter plate 2, and can make the movable filter plate 2 vibrate by squeezing to clean impurities in the filter holes.

[0041] In a further embodiment of the present invention, an elastic pressing component 9 is slidably installed on the inner wall of the sewage treatment chamber 1. The top of the elastic pressing component 9 is clamped and cooperated with each anode plate 3 and cathode plate 4, and the bottom of the elastic pressing component 9 is abutted and cooperated with the movable bracket 5. Specifically, the elastic pressing component 9 can press the electrode plate after the electrode plate is fully inserted into the sewage treatment chamber 1, so as to avoid it from shaking significantly during operation and ensure the stability of the overall structure. When the movable bracket 5 moves back and presses the shoe-shaped abutment plate on the movable filter plate 2, continued movement will cause the top of the movable bracket 5 to abut against the elastic pressing component 9, thereby forcing the elastic pressing component 9 to completely loosen each electrode plate, so as to facilitate quick maintenance and replacement and easy adjustment.

[0042] In a further embodiment of the present invention, the elastic pressing assembly 9 includes a connecting frame 91, a plurality of plug-in frames 92 are fixedly connected to the top of the connecting frame 91, and an anti-loosening fastening piece 93 is slidably installed on the top of the plug-in frame 92. A wedge-shaped groove 13 is provided on the inner wall of the sewage treatment chamber 1, which is inclined against the back of the anti-loosening fastening piece 93. A tension spring 94 is installed between the plug-in frame 92 and the bottom of the wedge groove 13. When the movable bracket 5 lifts the connecting frame 91, the anti-loosening fastening piece 93 is in a loose state. Specifically, when the movable bracket 5 pushes the connecting frame 91 upward, the plug-in frame 92 drives the anti-loosening fastening piece 93 to slide upward along the inclined surface of the wedge groove 13. The surface inclination angle converts vertical displacement into horizontal displacement, forcing the anti-loosening fastener 93 to move backward, and the tension spring 94 is in an extended state. At this time, the contact pressure between the fastener and the anode plate 3 or cathode plate 4 becomes smaller. In this state, the electrode plate can be freely fine-tuned to adapt to the impact of water flow, and it is also convenient for staff to quickly disassemble and assemble the electrode plate during inspection and maintenance. When the movable support frame 5 is reset, the tension spring 94 pulls the entire connecting frame 91 downward, allowing the anti-loosening fastener 93 to slide downward in the wedge-shaped groove 13. Its inclined surface frictionally contacts the wedge-shaped groove 13, and the anti-loosening support frame 82 increases the pressing force on the electrode plate again, so that the electrode plate is fixed without loosening. This structure significantly improves the efficiency of plate disassembly and assembly.

[0043] In a further embodiment of the present invention, an aeration pipe 10 is installed below the movable filter plate 2 inside the sewage treatment chamber 1, and a plurality of groups of aeration holes 101 are provided on the aeration pipe 10. The plurality of groups of aeration holes 101 are staggered with the anode plate 3 and the cathode plate 4, respectively. Specifically, a high-pressure air pump injects micro-nano bubbles into the sewage through the aeration pipe 10. When the bubble group rises, a spiral flow field is formed in the gap between the anode plate 3 and the cathode plate 4, thereby improving the efficiency of organic mass transfer. The staggered design of the aeration holes 101 and the electrode plate prevents the bubbles from directly impacting the electrode surface, and combines the strong oxidizing effect of the BDD electrode to increase the dissolved oxygen concentration.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
