Description

Technical Field

[0001] This invention relates to the field of medical wastewater treatment technology, specifically to a boron-doped diamond electrode medical wastewater treatment device. Background Technology

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

[0003] The existing patent application, with publication number CN220182895U and publication date of December 15, 2023, is titled "A Continuous Flow Wastewater Treatment Device Using Boron-Doped Diamond Electrodes." This patent includes a wastewater treatment chamber, electrodes, and a stirrer. The electrodes include a first boron-doped diamond anode, a first cathode, a second boron-doped diamond anode, and a second cathode, arranged sequentially. The stirrer includes a stirring shaft, a first stirring blade, and a second stirring blade. The stirring shaft and the first stirring blade connected to it are positioned between the first cathode and the second boron-doped diamond anode. The second stirring blade includes a blade portion and a connecting portion connecting the stirring shaft and the blade portion. When the second stirring blade rotates close to the first cathode, the blade portion is located between the first boron-doped diamond anode and the first cathode; when it rotates close to the second boron-doped diamond anode, the blade portion is located between the second boron-doped diamond anode and the second cathode. This design is well-suited for continuous flow treatment, achieving good wastewater treatment results while reducing the footprint of the treatment equipment.

[0004] The above application has shortcomings. Although adding a stirrer can improve the continuity of the treatment process, the surface of the electrode is still easily covered by contaminants during long-term operation, forming a passivation layer, which leads to a decrease in current efficiency. Secondly, the traditional fixed electrode structure is prone to water flow short circuit and low organic matter mass transfer efficiency. Furthermore, the filter unit and electrode system are set up independently, and the accumulation of suspended solids can easily cause blockage between the electrodes, requiring frequent shutdowns for cleaning, which also affects the continuity of treatment. Summary of the Invention

[0005] The purpose of this invention is to provide a boron-doped diamond electrode medical wastewater treatment device to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A boron-doped diamond electrode medical wastewater treatment device includes a wastewater treatment chamber, a movable filter plate elastically installed inside the wastewater treatment chamber, and several horizontally alternating anode plates and cathode plates inserted above the movable filter plate inside the wastewater treatment chamber. A movable support frame is installed inside the wastewater treatment chamber, with both ends of the movable support frame abutting against the top surface of the movable filter plate. A cleaning and trapping component and a turbulence-inducing component are installed on the top of the movable support frame between adjacent anode and cathode plates. A pair of combing frames are slidably installed on the cleaning and trapping components, with the bottom of the combing frames overlapping the top surface of the movable filter plate. When the movable support frame moves, it drives the turbulence-inducing components to rotate. When the movable support frame presses against the movable filter plate and lowers it, the turbulence-inducing components abut against the combing frames, causing the combing frames to reciprocate up and down on the cleaning and trapping components.

[0008] Preferably, a pair of adjusting screws threaded through a movable support frame are installed in the wastewater treatment chamber, and a drive motor connected to the adjusting screws is fixedly connected to the outside of the wastewater treatment chamber.

[0009] Preferably, both ends of the movable support frame are vertically installed with abutment columns, both sides of the top of the movable filter plate are symmetrically installed with wedge-shaped abutment plates, and both sides of the bottom of the movable filter plate are fixedly connected with top springs, the bottom of the top springs being fixed to the inner wall of the sewage treatment chamber.

[0010] Preferably, the cleaning and capturing assembly includes a capturing filter screen that is inserted and fixed to the top of the movable support frame, and cleaning brushes that are in contact with the anode plate and the cathode plate are respectively installed on both sides of the capturing filter screen.

[0011] Preferably, the turbulence assembly includes a rotating shaft rotatably mounted on the bottom of the trapping filter, an impeller mounted on the rotating shaft, a transmission shaft rotatably mounted inside the movable support frame, a transmission belt installed between the transmission shaft and each rotating shaft, and frictional transmission between the anode plate and the cathode plate and the transmission shaft.

[0012] Preferably, the top of the movable support frame is provided with several limiting grooves that match the anode plate and the cathode plate, and several anti-slip rings are fixedly sleeved on the transmission shaft. The anode plate and the cathode plate are in contact with the surface of each anti-slip ring, and the anti-slip rings are located in the limiting grooves.

[0013] Preferably, the combing frame has combing teeth symmetrically installed on one side, the cleaning brush is located between a pair of combing teeth, and an abutment frame is fixedly connected to the other side of the combing frame. The abutment frame is located above the rotating shaft, and an abutment protrusion that cooperates with the abutment frame is fixedly connected to the rotating shaft.

[0014] Preferably, an elastic clamping assembly is slidably installed on the inner wall of the wastewater treatment room. The top of the elastic clamping assembly is clamped and engaged with each anode plate and cathode plate, and the bottom of the elastic clamping assembly is engaged with a movable abutment.

[0015] Preferably, the elastic clamping assembly includes a connecting frame, a plurality of plug-in frames are fixedly connected to the top of the connecting frame, and an anti-loosening clamping member is slidably installed on the top of the plug-in frame. A wedge-shaped groove is provided in the inner wall of the sewage treatment chamber, which is inclined and abuts against the back of the anti-loosening clamping member. A tension spring is installed between the plug-in frame and the bottom of the wedge-shaped groove. When the movable clamping member lifts the connecting frame, the anti-loosening clamping member is in a loosened state.

[0016] Preferably, an aeration pipe is installed inside the wastewater treatment chamber below the movable filter plate, and the aeration pipe is provided with multiple sets of aeration holes, which are staggered from the anode plate and the cathode plate respectively.

[0017] In the above technical solution, through the linkage design of the flexible movable filter plate and the moving support frame, the cleaning and trapping components and the turbulence-disrupting components are integrated in the electrode array to achieve the synergistic effect of mechanical stripping and electrolytic oxidation of pollutants on the electrode plates. When the device is running, the movable filter plate filters the sewage entering the electrode area. When the moving support frame drives the cleaning and trapping components to move between the anode and cathode plates, the cleaning and trapping components adsorb impurities in the area they pass through and clean the surface of the electrode plates. The turbulence-disrupting components can also change the flow direction of sewage in the area they pass through, improving the mass transfer efficiency of organic matter. At the same time, when the flexible filter plate is pressed down by the moving support frame and falls rapidly, the force it receives can accelerate the reciprocating penetration of sewage above and below the flexible filter plate, avoiding filter pore blockage and affecting sewage treatment efficiency. Meanwhile, the combing frame can intermittently move the cleaning and trapping components after the flexible filter plate falls, driven by the turbulence-disrupting components, reducing the number of maintenance and treatment required.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0032] Please see Figure 1-8This invention provides a boron-doped diamond electrode medical wastewater treatment device, including a wastewater treatment chamber 1 and a movable filter plate 2, which is elastically installed inside the wastewater treatment chamber 1. Several horizontally alternating anode plates 3 and cathode plates 4 are inserted above the movable filter plate 2 inside the wastewater treatment chamber 1. A movable support frame 5 is installed inside the wastewater treatment chamber 1, and its two ends are respectively in contact with the top surface of the movable filter plate 2. A cleaning and collection component 6 and a turbulence-disrupting component 7 are installed on the top of the movable support frame 5 between adjacent anode plates 3 and cathode plates 4. A pair of combing frames 8 are slidably installed on the collection and cleaning components, and the bottom of the combing frames 8 overlaps the top surface of the movable filter plate 2. When the movable support frame 5 moves, it drives the turbulence-disrupting component 7 to rotate. When the movable support frame 5 presses against the movable filter plate 2 to make it descend, the turbulence-disrupting component 7 and the combing frames 8 are in contact, causing the combing frames 8 to reciprocate up and down on the cleaning and collection component 6.

[0033] Specifically, the movable filter plate 2 is installed in the wastewater treatment chamber 1 via an elastic element. The wastewater treatment chamber 1 has an inlet at the bottom of one side and an outlet at the top of the other side. The movable filter plate 2 initially has a certain distance between itself and the anode plate 3, allowing it to move downwards under pressure. The anode plate 3 and cathode plate 4 are alternately inserted horizontally into the wastewater treatment chamber 1. The surfaces of the plates are coated with boron-doped diamond. A channel for wastewater flow is formed between the anode plate 3 and the cathode plate 4, guiding the wastewater flow. The movable support frame 5 can be driven by a drive source to reciprocate back and forth within the wastewater treatment chamber 1. Its two ends can contact the top of the movable filter plate 2. When it moves to one side of the wastewater treatment chamber 1, it forces the movable filter plate 2 to descend rapidly. After entering the wastewater treatment chamber 1, the wastewater 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 further treatment. After continuous operation, the movable support frame 5 can move back and forth to drive the cleaning and collection component 6 to scrape. The device removes dirt from the electrode plate surface and simultaneously captures and adsorbs charged contaminants between the anode plate 3 and the cathode plate 4. The turbulence component 7 can also rotate and agitate the sewage between the anode plate 3 and the cathode plate 4 when the movable support frame 5 moves, causing the sewage to form turbulence between the electrode plates. The organic matter mass transfer rate is improved compared to traditional devices. At the same time, it combines dynamic filtration with anti-clogging. When the movable support frame 5 presses the movable filter plate 2 to the lowest point, the pressure below the movable filter plate 2 increases sharply, forcing some sewage to quickly penetrate the filter holes. When the movable filter plate 2 rebounds, it generates a negative pressure suction effect, peeling off the particles attached to the filter holes and restoring the filter plate flux. In addition, each time the movable filter plate 2 descends and rebounds, the combing frame 8 also completes a lifting and lowering action. When the movable filter plate 2 continues to descend under the pressure of the movable support frame 5, the combing frame 8 resting on the movable filter plate 2 at the bottom will move down and be intermittently pushed by the turbulence component 7 to quickly clear and clean the debris on the collection component 6, ensuring the cleaning effect of the collection component 6 on the electrode plates.

[0034] Compared with the prior art, the embodiments of the present invention integrate a cleaning and trapping component 6 and a turbulence-disrupting component 7 in the electrode array through the linkage design of the elastic movable filter plate 2 and the movable support frame 5. This achieves the synergistic effect of mechanical stripping and electrolytic oxidation of pollutants on the electrode plates. When the device is running, the movable filter plate 2 filters the sewage entering the electrode area. When the movable support frame 5 drives the cleaning and trapping component 6 to move between the anode plate 3 and the cathode plate 4, the cleaning and trapping component 6 adsorbs impurities in the area it passes through and cleans the surface of the electrode plates. The turbulence-disrupting component 7 can also change the flow direction of sewage in the area it passes through, improving the mass transfer efficiency of organic matter. At the same time, when the elastic filter plate is pressed down by the movable support frame 5 and descends rapidly, the force it receives can accelerate the reciprocating penetration of sewage above and below the elastic filter plate, avoiding filter pore blockage and affecting sewage treatment efficiency. Meanwhile, the combing frame 8 can intermittently move the cleaning and trapping component 6 after the elastic filter plate descends, driven by the turbulence-disrupting component 7, reducing the number of maintenance operations required.

[0035] In a further embodiment of the present invention, a pair of adjusting screws 11 threaded through the movable support frame 5 are installed in the sewage treatment chamber 1. A drive motor 12 connected to the adjusting screws 11 is fixedly connected to the outside of the sewage treatment chamber 1. Specifically, the drive motor 12 drives the movable support frame 5 to move back and forth in the sewage treatment chamber 1 through the adjusting screws 11. Its movement speed can be steplessly adjusted. In the low-speed mode, the cleaning and collecting component 6 performs deep scraping on the surfaces of the anode plate 3 and cathode plate 4 it contacts. In the high-speed mode, the cleaning and collecting component 6 performs rapid scraping. The turbulence component 7 rotates when the movable support frame 5 moves horizontally. The rotation speed increases synchronously with the moving speed of the movable support frame 5, which can form a high-intensity vortex 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 support frame 5 are vertically mounted with abutment columns 51, and both sides of the top of the movable filter plate 2 are symmetrically mounted with wedge-shaped abutment plates 21. Both sides of the bottom of the movable filter plate 2 are fixedly connected with top springs 22, and the bottom of the top springs 22 is fixed to the inner wall of the sewage treatment chamber 1. Specifically, the stroke position of the movable support frame 5 is dynamically related to the downward pressure of the movable filter plate 2. When the movable support frame 5 moves horizontally, if the abutment columns 51 slide along the inclined surface of the wedge-shaped abutment plates 21, the horizontal displacement will be converted into vertical downward pressure, forcing the movable filter plate 2... As the compression top spring 22 moves downward, it stores energy and generates high-frequency micro-vibrations during the downward pressing process, which increases the shedding rate of suspended solids in the filter plate pores. When the abutment column 51 disengages from the wedge-shaped inclined surface, the top spring 22 releases energy to push the movable filter plate 2 to reset. When the movable filter plate 2 rebounds, it generates a negative pressure suction effect, which peels off the particles attached to the filter holes. At the same time, the limiting block buffers and forms a secondary oscillation, which further enhances the reciprocating permeation of sewage. It can quickly press down the movable filter plate 2 to clean the debris blocking the filter holes, eliminating the need for frequent maintenance of the movable filter plate 2.

[0037] In a further embodiment of the present invention, the cleaning and collection assembly 6 includes a collection filter 61 that is inserted and fixed to the top of the movable support frame 5. Cleaning brushes 62 that contact the anode plate 3 and the cathode plate 4 are vertically installed on both sides of the collection filter 61. Specifically, when the movable support frame 5 drives the cleaning and collection 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 brushes 62 can adsorb or clean the debris attached to the plates. The collection filter 61 then intercepts the pollutants that fall off between adjacent plates, achieving multiple efficient impurity removal and accelerating the rate of organic matter decomposition.

[0038] In a further embodiment of the present invention, the turbulence assembly 7 includes a rotating shaft 71 rotatably mounted on the bottom of the trapping filter 61, an impeller 72 mounted on the rotating shaft 71, a transmission shaft 73 rotatably mounted inside the movable support frame 5, and a pair of transmission belts 74 installed between the transmission shaft 73 and each rotating shaft 71. The anode plate 3 and the cathode plate 4 are subjected to frictional transmission with the transmission shaft 73. Specifically, when the movable support frame 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 support 5 translates. Then, the transmission belt 74 drives the rotating shaft 71 to rotate, causing the impeller 72 to generate a reverse vortex between the anode plate 3 and the cathode plate 4. This effectively breaks up the biofilm and improves the mass transfer efficiency of organic matter, while also increasing the removal rate of deposits on the electrode surface. This achieves an adaptive combination of water flow dynamics and mechanical cleaning, enabling the cleaning brush 62 to quickly and efficiently clean the dirt on the electrode surface in accordance with changes in water flow, reducing the impact of impurities on wastewater treatment.

[0039] In a further embodiment of the present invention, the top of the movable support frame 5 is provided with a plurality of limiting grooves 54 that match the anode plate 3 and the cathode plate 4. A plurality of anti-slip collars 75 are fixedly sleeved 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 collars 75 are located in the limiting grooves 54. Specifically, the limiting grooves 54 are U-shaped with the groove opening facing upward. When the electrode plate is inserted into the sewage treatment chamber 1, the limiting grooves 54 can play a positioning role, and when the bottom of the anode plate 3 and the cathode plate 4 enter the phase... After the limiting groove 54 is closed, the anode plate 3 and cathode plate 4 are fixed in position within the limiting groove 54. Their bottoms continuously press against the surface of the anti-slip ring 75. Through friction, the transmission shaft 73 rotates at a constant speed during the translation process. The anti-slip ring 75 undergoes elastic deformation under the contact pressure to form an adaptive contact surface, ensuring transmission efficiency. When the transmission shaft 73 rotates, it also links the impeller 72 through the transmission belt 74, forming a spiral turbulence in the sewage, accelerating the flow speed of sewage between the anode plate 3 and 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 a cleaning brush 62 is located between a pair of combing teeth 81. An abutment frame 82 is fixedly connected to the other side of the combing frame 8. The abutment frame 82 is located above the rotating shaft 71, and an abutment protrusion 76 that cooperates with the abutment frame 82 is fixedly connected to the rotating shaft 71. Specifically, since the combing frame 8 rests on the top surface of the movable filter plate 2, the movable filter plate 2 rises and falls together with the movable filter plate 2. When the moving abutment frame 5 moves backward a certain distance, it can continue to move backward and press down the movable filter plate 2 by pressing the wedge-shaped abutment plate 21. At this time, the combing... The comb 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 comb frame 8 to rise. After the protrusion is out of contact, the comb frame 8 will automatically descend and reset under gravity. During this process, the comb teeth penetrate the gaps between the bristles of the cleaning brush 62 and peel off the tangled or attached contaminants. At the same time, when the comb frame 8 descends, it hits the movable filter plate 2, which can also cause the movable filter plate 2 to vibrate by squeezing to clean the impurities in the filter holes.

[0041] In a further embodiment of the present invention, an elastic clamping assembly 9 is slidably installed on the inner wall of the sewage treatment chamber 1. The top of the elastic clamping assembly 9 clamps and cooperates with each anode plate 3 and cathode plate 4, and the bottom of the elastic clamping assembly 9 abuts and cooperates with the movable abutment 5. Specifically, the elastic clamping assembly 9 can clamp the electrode plate after the electrode plate is fully inserted into the sewage treatment chamber 1 to prevent it from shaking significantly during operation and to ensure the stability of the overall structure. When the movable abutment 5 moves backward and presses against the shoe-shaped abutment plate on the movable filter plate 2, it will continue to move and cause the top of the movable abutment 5 to abut against the elastic clamping assembly 9, thereby forcing the elastic clamping assembly 9 to completely release each electrode plate, so as to facilitate quick maintenance and replacement and convenient adjustment.

[0042] In a further embodiment of the present invention, the elastic clamping 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 anti-loosening clamping members 93 are slidably installed on the top of the plug-in frames 92. A wedge-shaped groove 13 is provided on the inner wall of the sewage treatment chamber 1, which is inclined and abuts against the back of the anti-loosening clamping member 93. A tension spring 94 is installed between the plug-in frame 92 and the bottom of the wedge-shaped groove 13. When the movable abutment 5 lifts the connecting frame 91, the anti-loosening clamping member 93 is in a loosened state. Specifically, when the movable abutment 5 pushes the connecting frame 91 upward, the plug-in frame 92 drives the anti-loosening clamping member 93 to slide upward along the inclined surface of the wedge-shaped groove 13. The tilt angle converts vertical displacement into horizontal displacement, forcing the anti-loosening clamping member 93 to move backward. The tension spring 94 is in an extended state, reducing the contact pressure between the clamping member and the anode plate 3 or cathode plate 4. In this state, the electrode plate can be freely and finely adjusted to adapt to water flow impact, and it also facilitates quick disassembly and assembly of the electrode plate during maintenance. When the moving abutment 5 resets, the tension spring 94 pulls the entire connecting frame 91 downward, allowing the anti-loosening clamping member 93 to slide downward within the wedge groove 13. Its inclined surface rubs against the wedge groove 13, increasing the clamping force of the anti-loosening abutment frame 82 on the electrode plate, thus ensuring the electrode plate is fixed without loosening. This structure significantly improves the efficiency of electrode plate disassembly and assembly.

[0043] In a further embodiment of the present invention, an aeration pipe 10 is installed inside the wastewater treatment chamber 1 below the movable filter plate 2. The aeration pipe 10 is provided with multiple sets of aeration holes 101, which are staggered from the anode plate 3 and the cathode plate 4, respectively. Specifically, a high-pressure air pump injects micro-nano bubbles into the wastewater 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, which improves the efficiency of organic matter mass transfer. The staggered design of the aeration holes 101 and the electrode plates avoids the bubbles from directly impacting the electrode surface. Combined with the strong oxidation effect of the BDD electrode, the dissolved oxygen concentration is increased.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
