Description

Technical Field

[0001] The invention relates to the technical field of electric flocculation devices, in particular to an adjustable self-cleaning electric flocculation device. Background Art

[0002] The electrocoagulation wastewater treatment device is a new water treatment technology based on electrochemical principles. It forms flocculants by combining the metal ions (such as Fe3+, Al3+) released by the dissolution of the anode metal during the electrolysis process with the OH- produced by the cathode electrolysis of water, thereby achieving adsorption, coagulation and flotation separation of pollutants.

[0003] However, in the existing wastewater electrocoagulation process, since the electrodes usually use a fixed electrode spacing, it is difficult for the fixed electrode spacing to adapt to different water qualities or changes in pollutant concentrations, resulting in excessively high or low local current density. For example, in wastewater with high conductivity, the current tends to concentrate on the edge of the electrode, causing an "edge effect" and exacerbating electrode passivation; while in wastewater with low conductivity, the current distribution is dispersed, reducing the efficiency of metal ion dissolution and prolonging the reaction time;

[0004] At the same time, a large amount of dirt will be attached to the electrode after electrocoagulation, which is difficult to clean. In the prior art, the electrode surface is usually cleaned by a high-pressure water gun after the electrolysis of the equipment is completed. The high-pressure water gun cleaning needs to be carried out after the equipment is completely shut down, resulting in interruption of the electrocoagulation treatment, which is difficult to meet the needs of continuous industrial wastewater treatment. In particular, for high-load wastewater treatment scenarios (such as electroplating and printing and dyeing wastewater), the overall processing capacity of the system will be significantly reduced. At the same time, it relies on manual operation of high-pressure water gun cleaning, and it is necessary to frequently enter the internal operation of the equipment, which increases labor intensity and personnel safety risks (such as accidental injury by high-pressure water and risk of contact with residual chemical substances on the electrode). At the same time, manual cleaning is inefficient and difficult to achieve automatic control, which is contrary to the intelligent operation characteristics of electrocoagulation technology.

[0005] Therefore, an adjustable self-cleaning electrocoagulation device is proposed to solve the above problems. Summary of the invention

[0008] The electrode plate spacing adjustment mechanism is arranged at the bottom of the electric flocculation cell, and the electrode plate spacing adjustment mechanism is used to adjust the spacing between the first electrode plate and the second electrode plate;

[0009] The self-oscillating mechanism is arranged above the first pole plate, and the self-oscillating mechanism is used to vibrate and remove impurities from the first pole plate;

[0010] The self-cleaning mechanism is arranged in the middle of the electric flocculation cell, and is used for self-regulating cleaning of the first electrode plate.

[0011] Preferably, the electrode plate spacing adjustment mechanism includes a telescopic cylinder, an electric coagulation cell is installed on one side of the electric coagulation cell, a pull plate is fixedly connected to the electric coagulation cell driving shaft, and the pull plate is slidably connected to the bottom of the electric coagulation cell.

[0013] Preferably, the self-oscillation mechanism comprises a card plate, which is clamped on the upper end of the first pole plate, and a vibration spring is symmetrically fixedly connected to the upper surface of the card plate, and one end of the vibration spring away from the card plate is clamped on the support plate.

[0014] Preferably, an oscillation block is fixedly connected to the middle of the card plate, a collision hole begins to be formed in the middle of the oscillation block, a convex shaft is arranged in the collision hole of the oscillation block, both ends of the convex shaft are rotatably connected to the bottom of the support plate, and one end of the convex shaft is fixedly connected to the motor drive shaft.

[0015] Preferably, a transmission disc is symmetrically rotatably connected to the outer surface of one side of the electric coagulation cell, and the outer surface of the transmission disc is transmission-connected to a first transmission belt, to which a scraper is fixedly connected, and the scraper slides on the upper surface of the electric coagulation cell.

[0016] Preferably, the self-cleaning mechanism includes a driving disk, a turbine fan is fixedly connected to the upper middle end of the driving disk, a second transmission belt is transmission-connected to the outer surface of the driving disk, the second transmission belt is uniformly transmission-connected to a T-shaped turntable at one end away from the driving disk, the T-shaped turntable is rotatably connected to the bottom of the electric incoherence cell, a swing plate is symmetrically rotationally connected to the upper end of the T-shaped turntable, and the swing plate is rotationally connected to the turntable at one end away from the T-shaped turntable.

[0017] Preferably, a support plate is fixedly connected in the electric incoherence cell, a guide groove is opened in the middle of the support plate, the turntable is slidably connected in the guide groove of the support plate, the outer surface of the turntable is transmission-connected to a third transmission belt, and the third transmission belt is transmission-connected to the motor drive disk at one end away from the turntable.

[0019] Compared with the prior art, the present invention provides an adjustable self-cleaning electro-flocculation device, which has the following beneficial effects:

[0020] 1. The extension of the telescopic cylinder can drive the extrusion column to adjust the gap between the second electrode plate and the first electrode plate.

At the same time, the cleaning rod can be adjusted to fit the surface of the first electrode plate according to the degree of impurity adhesion on the surface of the first electrode plate, so that the attachments on the surface of the first electrode plate can be cleaned more effectively. Compared with the prior art, this design is not only more flexible, but also can make the cleaning of attachments on the surface of the first electrode plate more thorough by coordinating cleaning with the vertical oscillation of the self-oscillation mechanism.

[0023] 3. This solution uses a third conveyor belt to synchronously drive multiple cleaning rods to rotate, which can not only effectively clean the stubborn impurities on the surface of the first electrode plate, but also quickly flocculate the attachments on the surface of the first electrode plate in the water through the cooperation of the turbine fan and the bubbles at the bottom of the electric flocculation cell. Traditional equipment needs to be shut down regularly for acid washing to remove the electrode scale layer, while the oscillation and scraping design can achieve in-situ cleaning, reduce the use of chemical agents by 80%, and extend the maintenance cycle from weekly to quarterly. The electrode surface is cleaned to maintain a low resistance state, avoiding voltage increase due to scaling, and reducing comprehensive energy consumption by 15%-20%.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Next, the present invention will be further described in detail according to the drawings and embodiments.

[0038] First embodiment

[0039] Please refer to Figures 1 to 7 as shown:

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides an adjustable self-cleaning electric flocculation device, including an electric flocculation cell 1, a support plate 11 is slidably connected to the electric flocculation cell 1, a first electrode plate 12 is evenly arranged in the electric flocculation cell 1, a second electrode plate 13 is staggered in the support plate 11, and also includes an electrode plate spacing adjustment mechanism 2, a self-oscillation mechanism 3 and a self-cleaning mechanism 4;

[0041] The electrode plate spacing adjustment mechanism 2 is arranged at the bottom of the electric flocculation cell 1, and the electrode plate spacing adjustment mechanism 2 is used to adjust the spacing between the first electrode plate 12 and the second electrode plate 13;

[0042] The self-oscillating mechanism 3 is disposed above the first pole plate 12, and the self-oscillating mechanism 3 is used to vibrate and remove impurities from the first pole plate 12;

[0043] The self-cleaning mechanism 4 is arranged in the middle of the electric flocculation cell, and the self-cleaning mechanism 4 is used for self-regulating cleaning of the first electrode plate 12;

[0044] Specifically, Figure 3 As shown, an electric flocculation cell 1 is installed on one side of the electric flocculation cell 1, a pull plate 22 is fixedly connected to the driving shaft of the electric flocculation cell 1, and the pull plate 22 is slidably connected to the bottom of the electric flocculation cell 1; extrusion grooves 23 are evenly opened on the pull plate 22, and an extrusion column 24 is slidably connected in the extrusion groove 23, and the extrusion column 24 is fixedly connected to the bottom of the second electrode plate 13 at one end away from the extrusion groove 23, and the second electrode plate 13 is evenly slidably connected in the electric flocculation cell 1;

[0045] Among them, the extension of the telescopic cylinder 21 can drive the extrusion column 24 to drive the gap between the second electrode plate 13 and the first electrode plate 12 to adjust. When the distance between the first electrode plate 12 and the second electrode plate 13 is reduced, the gap can be reduced to 5-10mm to increase the current density, accelerate the dissolution of the anode metal Fe / Al, and quickly generate a large amount of flocculants such as Al3+, Fe2+, and enhance the adsorption capacity of suspended matter and heavy metals; compared with the fixed spacing between the electrodes in the prior art, by dynamically adjusting the electrode spacing, it can accurately match wastewaters with different conductivity, such as high-salt wastewater and low-conductivity organic wastewater, to make the current density distribution more uniform. For example, increasing the electrode spacing of low-conductivity wastewater can reduce ineffective energy consumption, while reducing the spacing of high-conductivity wastewater can enhance the electric field strength, improve the metal ion dissolution efficiency, and shorten the treatment cycle to 30-60 minutes.

[0046] At the same time, increase the spacing to 15-20mm to reduce the current density, reduce the production of H2 at the cathode by the hydrogen evolution side reaction, and maintain a local high pH environment in the cathode area OH - Enrichment, promote the precipitation of CaCO3 / Mg(OH)2 microcrystals, control the anode dissolution rate by adjusting the spacing, avoid surface deposition caused by excessive release of metal ions such as Fe3O4 and Al2O3, and delay electrode passivation;

[0047] At the same time, the resistivity of the water in this scheme increases with the increase of the distance between the plates. By intelligently adjusting the distance and voltage matching, the ohmic loss can be reduced while ensuring the reaction efficiency. Experiments show that energy saving can be 15% to 25%.

[0048] Further, if Figure 5 As shown, the card plate 31 is clamped on the upper end of the first pole plate 12, and the upper surface of the card plate 31 is symmetrically fixedly connected with a vibration spring 32, and the end of the vibration spring 32 away from the card plate 31 is clamped on the support plate 11; the middle of the card plate 31 is fixedly connected with an oscillation block 34, and a collision hole is formed at the middle of the oscillation block 34, and a convex shaft 33 is arranged in the collision hole of the oscillation block 34, and both ends of the convex shaft 33 are rotatably connected to the bottom of the support plate 11, and one end of the convex shaft 33 is fixedly connected to the motor drive shaft;

[0049] The clamping plate 31 is quickly inserted into the upper end of the first pole plate 12 laterally, and the first pole plate 12 can be quickly disassembled after use. Compared with the fixed installation of the prior art, the complexity of equipment installation and disassembly is reduced. In addition, by setting the convex shaft 33 to rotate in the collision hole of the oscillation block 34, the eccentric rotation of the convex shaft 33 can drive the first pole plate 12 to oscillate vertically, so that impurities flocculated on the surface of the first pole plate 12 can fall off quickly.

[0050] Specifically, Figure 7 As shown, a turbine fan 42 is fixedly connected to the upper middle end of the driving disk 41, a second transmission belt 43 is transmission-connected to the outer surface of the driving disk 41, and a T-shaped turntable 44 is uniformly transmission-connected to the end of the second transmission belt 43 away from the driving disk 41, and the T-shaped turntable 44 is rotationally connected to the bottom of the electric cocoon cell 1, and a swing plate 45 is symmetrically rotationally connected to the upper end of the T-shaped turntable 44, and a turntable 46 is rotationally connected to the end of the swing plate 45 away from the T-shaped turntable 44; a support plate 48 is fixedly connected to the electric cocoon cell 1, a guide groove is opened in the middle of the support plate 48, and the turntable 46 is slidably connected in the guide groove of the support plate 48, and a third transmission belt 49 is transmission-connected to the outer surface of the turntable 46, and the end of the third transmission belt 49 away from the turntable 46 is transmission-connected to the motor driving disk;

[0051] The present solution sets a cleaning rod 47 with an adjustable spacing. By adjusting the cleaning rod 47, the cleaning rod 47 can be quickly adapted to the removal of different impurities on the surface of the first electrode plate 12. At the same time, the cleaning rod 47 can be adjusted to fit the surface of the first electrode plate 12 according to the degree of impurity adhesion on the surface of the first electrode plate 12, so that the attachments on the surface of the first electrode plate 12 can be cleaned more effectively. Compared with the prior art, the design of the present solution is not only more flexible, but also can make the cleaning of attachments on the surface of the first electrode plate 12 more thorough by coordinating the cleaning with the vertical oscillation of the self-oscillation mechanism 3.

[0052] Furthermore, a cleaning rod 47 is fixedly connected to the middle of the upper end of the turntable 46. The outer surface of the cleaning rod 47 is made of a flexible corrosion-resistant material. Bubble tubes are evenly installed at the bottom of the electrocoagulation cell 1 for the flocculation of impurities.

[0053] In this solution, the third conveyor belt 49 synchronously drives a plurality of cleaning rods 47 to rotate. This can not only effectively clean the stubborn impurities on the surface of the first electrode plate 12, but also make the attachments on the surface of the first electrode plate 12 quickly coagulate in the water through the cooperation of the turbine fan 42 and the bubbles at the bottom of the electrocoagulation cell 1. Traditional equipment needs to stop regularly for pickling to remove the electrode scale layer. However, the oscillation and scraping design can achieve in-situ cleaning, reducing the chemical agent consumption by 80%. The maintenance cycle is extended from weekly to quarterly. The surface of the electrode is kept in a low-resistance state during cleaning, avoiding the voltage increase caused by scaling. Under the same current, the scaled electrode needs to increase the voltage by 20%-30%. The comprehensive energy consumption is reduced by 15%-20%.

[0054] Furthermore, drive disks 35 are symmetrically and rotatably connected to the outer surface of one side of the electrocoagulation cell 1. A first conveyor belt 36 is drivingly connected to the outer surface of the drive disks 35. A scraper 37 is fixedly connected to the first conveyor belt 36. The scraper 37 slides on the upper surface of the electrocoagulation cell 1.

[0055] By scraping the water surface with the scraper 37, the flocculent condensed impurities on the water surface can be quickly cleaned, increasing the cleanliness inside the equipment and reducing the influence of flocs on the electrolysis of impurities in the water.

[0056] The specific implementation process of the above embodiment is as follows:

[0057] Step 1: First, start the equipment and perform self-check

[0058] After the equipment is powered on, the AIoT intelligent control system starts the self-check program to confirm the normal state of the electrodes (such as whether they are passivated or scaled), the calibration of sensors (pH, ORP, turbidity, conductivity), and the proper functioning of mechanical components (such as the electrode rotation motor and the spacing adjustment device).

[0059] Step 2: Input water quality parameters

[0060] Input the initial parameters of the water to be treated (such as turbidity, hardness, heavy metal concentration, flow rate), or detect them in real time through sensors. The system generates an initial operation strategy according to a preset algorithm (such as fuzzy logic or machine learning model):

[0061] Electrocoagulation priority mode (high turbidity / heavy metal water quality): Narrow the electrode spacing (5 - 10 mm), and set a high-frequency pulse (30 kHz, duty cycle 50%).

[0062] Electrode descaling priority mode (high hardness / alkalinity water quality): Increase the electrode spacing (15 - 20 mm), and switch to the reverse pulse mode (10 kHz, duty cycle 30%).

[0063] The adjustment of the motor spacing is specifically as follows:

[0064] First, as Figure 3 shown, under the control of the controller, the telescopic cylinder 21 is started to expand and contract. The expansion and contraction of the telescopic cylinder 21 will drive the sliding plate 22 to slide at the bottom of the electrocoagulation cell 1. At this time, under the sliding of the sliding plate 22, the mutual extrusion between the extrusion groove 23 and the extrusion column 24 will drive the second electrode plate 13 to slide evenly in the electrocoagulation cell 1. Since the first electrode plate 12 and the second electrode plate 13 are arranged in an alternating manner, the electrode spacing can be adjusted by controlling the sliding distance between the second electrode plate 13 and the first electrode plate 12. In this scheme, the expansion of the telescopic cylinder 21 can drive the extrusion column 24 to adjust the gap between the second electrode plate 13 and the first electrode plate 12. When the distance between the first electrode plate 12 and the second electrode plate 13 is reduced, reducing the spacing by 5 - 10 mm can increase the current density, accelerate the dissolution of the anode metal Fe / Al, quickly generate a large amount of flocculants such as Al3+ and Fe2+, and enhance the adsorption capacity for suspended solids and heavy metals; compared with the prior art where a fixed spacing is used between the electrode plates, once the plate spacing is too small, it is easy to cause too high a current density, resulting in the passivation of the anode surface and the formation of an oxide film that hinders dissolution or the deposition of microcrystals on the cathode scale, blocking the surface. By adjusting the spacing in real time, extreme working conditions can be avoided and the electrode life can be extended.

[0065] Step 3: Implementation of the electrocoagulation stage

[0066] Electrode activation and metal ion release

[0067] Start the pulsed composite power supply: Apply a positive DC voltage (15 - 30 V) superimposed with a high-frequency pulse (20 - 50 kHz). The anode (Fe / Al) starts electrolysis and releases Fe2+ / Al3+ ions.

[0068] Adjust the electrode spacing: Reduce the electrode plate spacing to the target value (such as 8 mm) through the servo motor, and increase the current density to 80 A / m 2 , accelerating the dissolution of the anode.

[0069] Implementation of the electroscale removal stage

[0070] Power supply mode switching and reverse pulse

[0071] Polarity reversal: Turn off the positive power supply, apply a reverse pulse voltage (5 - 12) V, duty cycle 30%), the original cathode becomes the anode, and the CaCO / Mg(OH) microcrystals deposited on the surface are dissolved.

[0072] Increase the electrode spacing: Adjust the electrode plate spacing to 15 - 20 mm, reduce the current density to 20 A / m 2 , reduce the hydrogen evolution side reaction, and at the same time maintain the pH > 10 in the cathode area.

[0073] Swirl separation and scale removal

[0074] A scum collection tank is arranged at the top of the swirl chamber, and light microcrystalline scale (density 1.5 - 2.0 g / cm 3 ) floats into the collection tank along with the bubbles.

[0075] The bottom sludge pump discharges heavy flocs (density > 2.5 g / cm 3 ) regularly.

[0076] Step Four: Self-cleaning and maintenance

[0077] Electrode polarity reversal cleaning

[0078] The polarity of the entire electrode group is automatically reversed every day (for 5 minutes), and the reverse current is used to dissolve the oxide film on the anode surface and the scale on the cathode.

[0079] The electrode plates are cleaned by starting the self-oscillation mechanism 3 and the self-cleaning mechanism 4:

[0080] The specific operation steps are as follows:

[0081] First, the support plate 11 is electrically controlled as a whole through the bottom pulley, and the first and second plates 12 and 13 of the cathode and anode are separated by the support plate 11. At this time, the impurities attached to the first plate 12 will move to the self-cleaning mechanism 4 along with the support plate 11. When the first plate 12 moves between the cleaning rods 47, the motor at the bottom of the electric flocculation cell 1 is started. Since the motor drive shaft is fixed in the middle of the drive disk 41, the rotation of the motor will synchronously drive the turbine fan 42 to rotate. The rotation of the turbine fan 42 can stir the water in the electric flocculation cell 1 to generate a vortex. At the same time, the second transmission belt 43 can be used to quickly adjust the cleaning rod 47 to the first plate 12. The pole plate 12 is clamped and fitted, and then the motors installed on both sides of the support plate 48 are started again. The motor start-up can quickly drive the cleaning rod 47 to rotate under the transmission of the third transmission belt 49, and further the servo motor at the bottom of the support plate 11 is started to rotate. The rotation of the servo motor can drive the convex shaft 33 to eccentrically collide with the collision hole of the oscillation block 34, and the first pole plate 12 can be driven to oscillate vertically through the collision. The cleaning rod 47 rotates and cleans the surface of the first pole plate 12 and the first pole plate 12 self-oscillates, so that the first pole plate 12 can clean impurities into the water more quickly, and the scraper 37 can clean the floccules in the water. The present solution sets a cleaning rod 47 with an adjustable spacing. By adjusting the cleaning rod 47, the cleaning rod 47 can be quickly adapted to the removal of different impurities on the surface of the first electrode plate 12. At the same time, the cleaning rod 47 can be adjusted to fit the surface of the first electrode plate 12 according to the degree of impurity adhesion on the surface of the first electrode plate 12, so that the attachments on the surface of the first electrode plate 12 can be cleaned more effectively. Compared with the prior art, the design of the present solution is not only more flexible, but also can make the cleaning of attachments on the surface of the first electrode plate 12 more thorough by coordinating the cleaning with the vertical oscillation of the self-oscillation mechanism 3.
