Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an electrocoagulation sludge dewatering treatment device. Background Art

[0002] With the rapid development of industrialization and urbanization, the number of sewage treatment plants has been increasing continuously, and the sludge production has also increased significantly. Sludge contains a large amount of water, organic matter, heavy metals, pathogens, etc. If not properly treated, it will cause serious pollution to the environment. Traditional sludge treatment methods mainly include landfill, incineration, composting, etc. Landfill will occupy a large amount of land resources and may pollute groundwater; incineration requires a large amount of energy consumption and will produce secondary pollution; composting has a long treatment cycle and limited application scope. Therefore, it has become an urgent task to find an efficient and environmentally friendly sludge treatment technology.

[0003] Electrocoagulation is a technology that uses the electrochemical principle to treat wastewater and sludge. During the electrocoagulation process, direct current is passed into the wastewater, causing metal ions to be generated at the anode. These metal ions combine with hydroxide ions in the water to form flocculants. The flocculants can adsorb and aggregate suspended solids, organic matter, heavy metal ions, etc. in the wastewater to form larger flocs, thereby achieving the purification of wastewater and the dewatering of sludge.

[0004] When the existing electrocoagulation sludge dewatering treatment device needs to improve the reaction efficiency and reaction time, it usually does not involve the adjustment of electrodes. For some devices involving electrode adjustment, the electrodes are not efficiently utilized. A relatively simple electrode material shape is used, and a device is set to clean the sludge flocculated on the electrode surface, resulting in a decrease in reaction efficiency, an extension of the reaction time, and a significant reduction in the electrocoagulation effect.

[0045] Example 1: Refer to Figures 1 - 5, the present invention provides a technical solution: an electrocoagulation sludge dewatering treatment device, including a base 1, the upper surface of the bottom of the base 1 is fixedly connected with a support column 2, the top of the support column 2 is fixedly connected with a reaction tank 5, the left side of the reaction tank 5 is fixedly connected with a feed inlet 4, the inside of the reaction tank 5 is fixedly connected with an electrode adjustment mechanism 3, the outer surface of the electrode adjustment mechanism 3 is fixedly connected with an anode cleaning mechanism 6 and an anode replacement mechanism 9, the bottom of the reaction tank 5 is fixedly connected with a support plate 11, the right side of the reaction tank 5 is fixedly connected with a dewatering system 7, the upper surface of the base 1 is fixedly connected with a waste material tank 8 and a clear liquid tank 10, the upper surface of the support plate 11 is fixedly connected with a first motor 12, the output end of the first motor 12 is fixedly connected with a fan blade 13, and further includes:

[0046] The electrode adjustment mechanism 3, the electrode adjustment mechanism 3 includes a first connection block 301, the bottom of the first connection block 301 is fixedly connected with the upper surface of the reaction tank 5, the outer surface of the first connection block 301 is fixedly connected with a first lead screw 302, the outer surface of the first lead screw 302 is threadedly connected with a first slider 303 and a second slider 304, the first slider 303 and the second slider 304 are threadedly connected with a screw 305 through a threaded hole, and the inside of the first slider 303 is fixedly connected with a first distance sensor 306.

[0047] The electrode adjustment mechanism 3 further includes a second lead screw 308, the second lead screw 308 is fixedly connected with the inner wall bottom of the reaction tank 5, the outer surface of the second lead screw 308 is threadedly connected with a bushing 309, the inside of the bushing 309 is fixedly connected with a second distance sensor 310, the inner surface of the bushing 309 is fixedly connected with an arc-shaped cathode plate 312, the top of the arc-shaped cathode plate 312 is fixedly connected with a first arc-shaped rubber block 313, and the bottom of the arc-shaped cathode plate 312 is fixedly connected with a support cylinder 314;

[0048] The inner wall bottom of the reaction tank 5 is fixedly connected with the second lead screw 308 through a card slot, the arc-shaped anode plate 307 is fixedly connected with the first slider 303 through a special-shaped connection block 905, a fourth motor 904, a card slot connection block 903, a spring 902, and a telescopic rod 901. By setting the electrode adjustment mechanism 3, the distance between the electrodes is adjusted. The co-directional and reverse distance adjustment of the anode and the cathode is realized through the first lead screw 302 and the second lead screw 308. The co-directional adjustment improves the operation efficiency and stability in industrial production through the first distance sensor 306 and the second distance sensor 310, and adapts to different sludge treatment amounts or treatment requirements. The reverse adjustment changes the symmetry of the electric field distribution through the first distance sensor 306 and the second distance sensor 310, thereby changing the flocculation effect and adapting to different sludge treatment amounts.

[0049] The working principle of this embodiment is as follows: When using this electrocoagulation sludge dewatering treatment device, the sludge enters the reaction tank 5 through the feed port 4, undergoes an electrocoagulation reaction through the electrodes inside the reaction tank 5, and part of the reaction efficiency is improved through the first motor 12 and the fan blade 13, and then enters the dewatering system 7.

At this time, the second lead screw 308 rotates, driving the bushing 309 to move. The bushing 309 drives the arc-shaped cathode plate 312, the first arc-shaped rubber block 313, and the support cylinder 314 to move. The support cylinder 314 provides auxiliary support, and the bellows 311 protects the stable movement of the bushing 309. The first distance sensor 306 and the second distance sensor 310 realize the control of the distance and direction, and realize the movement of equal distance in the opposite direction at the same time or the movement of equal distance in the same direction at the same time.

[0050] Embodiment 2: Please refer to Figures 6 - 9 , on the basis of Embodiment 1, the present invention provides a technical solution: The anode cleaning mechanism 6 includes a first flexible bellows 601, which is clamped through a rectangular card slot opened at the top of the reaction tank 5. The outer surface of the first flexible bellows 601 is fixedly connected with a first clamping block 602. The inside of the upper surface of the first clamping block 602 is fixedly connected with a second motor 603 through a through hole. The output end of the second motor 603 is fixedly connected with a first connecting rod 604. The outer surface of the first connecting rod 604 is fixedly connected with a cleaning block 605. The inner wall of the reaction tank 5 is fixedly connected with an adjusting component 6001. The adjusting component 6001 includes a second connecting block 609, which is fixedly connected with the inner wall of the reaction tank 5. The inside of the second connecting block 609 is rotatably connected with a rotating block 610 through a rotating shaft. The top of the rotating block 610 is fixedly connected with a hydraulic pump 611. The outer surface of the output end of the hydraulic pump 611 is fixedly connected with a second flexible bellows 612. The bottom of the hydraulic pump 611 is fixedly connected with a third connecting block 613. The inside of the third connecting block 613 is rotatably connected with a first rotating shaft 615 through a through hole. The top and bottom of the first rotating shaft 615 are fixedly connected with a fourth connecting block 614. The top of the fourth connecting block 614 is fixedly connected with a torsion spring 616. The outer surface of the fourth connecting block 614 is fixedly connected with an arc-shaped cleaning column 617;

[0051] A first protective cover 606 is fixedly connected to the top of the special-shaped connecting block 905. A third motor 607 is fixedly connected to the inner wall of the first protective cover 606. The output end of the third motor 607 is fixedly connected to a cam 608. Two sets of adjusting components 6001 are symmetrically arranged on the outer surface of the arc-shaped cleaning column 617, and two sets of anode cleaning mechanisms 6 are symmetrically arranged on the outer surface of the arc-shaped anode plate 307. By providing the anode cleaning mechanism 6, the cleanliness of the surface of the arc-shaped anode plate 307 is ensured, the adsorbed sludge is effectively removed, the smooth flow of the current is guaranteed, and thus a stable and efficient electrocoagulation reaction is maintained; for the cleaning of the sludge in the holes of the arc-shaped anode plate 307, the service life of the arc-shaped anode plate 307 is extended, and the quality and effect of the electrocoagulation reaction are guaranteed.

[0052] The working principle of this embodiment is as follows: When using the electrode, its surface needs to be cleaned to maintain a high-efficiency reaction. At this time, the third motor 607 rotates, driving the cam 608 to rotate. The rotation of the cam 608 generates vibration, which is transmitted to the arc-shaped anode plate 307 through the special-shaped connecting block 905, causing it to vibrate. The second motor 603 rotates, driving the first connecting rod 604 and the cleaning block 605 to rotate, and the cleaning block 605 contacts the inner surface of the arc-shaped anode plate 307, enhancing the cleaning effect. The vibration of the arc-shaped anode plate 307 further improves the cleaning effect. The hydraulic pump 611 pushes the arc-shaped cleaning column 617 through the third connecting block 613, the fourth connecting block 614, the first rotating shaft 615 and the torsion spring 616, so that the inner surface of the arc-shaped cleaning column 617 contacts the outer surface of the arc-shaped anode plate 307 for cleaning. The torsion spring 616 enables the arc-shaped cleaning column 617 to closely fit and rotate on the outer surface of the arc-shaped anode plate 307 for cleaning. The symmetrically arranged anode cleaning mechanisms 6 completely clean the arc-shaped anode plate 307. The settings of the torsion spring 616 and the hydraulic pump 611 ensure that the anode cleaning mechanism 6 has no impact on the arc-shaped anode plate 307 when it moves. The second flexible bellows 612 protects the hydraulic pump 611.

[0053] Embodiment Three: Please refer to Figures 10 - 11, on the basis of the first embodiment and the second embodiment, the present invention provides a technical solution: The anode replacement mechanism 9 includes a telescopic rod 901, the telescopic rod 901 is fixedly connected to the bottom of the first slider 303, a groove connection block 903 is clamped at the bottom of the telescopic rod 901, a spring 902 is fixedly connected to the upper surface of the groove connection block 903, a fourth motor 904 is fixedly connected to the bottom of the groove connection block 903, an output end of the fourth motor 904 is fixedly connected to a special-shaped connection block 905, a first circular column 906 and a second circular column 907 are fixedly connected to the bottom of the special-shaped connection block 905, a second arc-shaped rubber block 908 is fixedly connected to the bottom of the first circular column 906, a third arc-shaped rubber block 909 is fixedly connected to the bottom of the second circular column 907, and an arc-shaped anode plate 307 is rotatably connected to the outer surfaces of the first circular column 906 and the second circular column 907;

[0054] The arc-shaped anode plate 307 is clamped to the outer surfaces of the first circular column 906 and the second circular column 907, and the length of the arc-shaped anode plate 307 is the same as that of the first circular column 906. By providing the anode replacement mechanism 9, the arc-shaped anode plate 307 will gradually wear out over time and with frequent use. When the anode is severely worn, the arc-shaped anode plate 307 can be replaced through the special-shaped connection block 905, the first circular column 906, and the second circular column 907, which can provide sufficient electric field strength for the electrocoagulation reaction, promote the generation of flocculants and the aggregation of sludge, thereby realizing an efficient electrocoagulation reaction.

[0055] The working principle of this embodiment is as follows: When the loss of the arc-shaped anode plate 307 is too large and affects the reaction efficiency, it needs to be replaced. At this time, the fourth motor 904 starts to rotate, driving the special-shaped connecting block 905 to rotate, driving the rotation of the first circular column 906 and the second circular column 907, and driving the rotation of the arc-shaped anode plate 307. When it corresponds to the notch on the reaction tank 5, it stops rotating. At this time, the first clamping block 602 is pushed to move away from the arc-shaped notch, and the screw 305 is removed to loosen it from the first lead screw 302. At this time, the first slider 303 is rotated to move away from the arc-shaped notch and disengage from the first lead screw 302. At this time, the anode replacement mechanism 9 is pulled upward to move out of the reaction tank 5. By removing the second arc-shaped rubber block 908 and the third arc-shaped rubber block 909, a new arc-shaped anode plate 307 is placed. By fixing the second arc-shaped rubber block 908, the third arc-shaped rubber block 909, the first circular column 906 and the second circular column 907 again, the replacement of the arc-shaped anode plate 307 is realized. The first arc-shaped rubber block 313, the second arc-shaped rubber block 908 and the third arc-shaped rubber block 909 are used to avoid direct contact between the anode and the cathode. The fixing of the second arc-shaped rubber block 908, the third arc-shaped rubber block 909, the first circular column 906 and the second circular column 907 further ensures the effect of non-direct contact. The spring 902 part transmits rotation to keep the first slider 303 stable during replacement.
