Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrocoagulation intelligent control systems, and particularly relates to an electrocoagulation intelligent control system. Background Technique
[0002] Electrocoagulation is an effective water treatment technology. Its basic principle is to apply direct current in an electrolytic cell, causing the anode metal to undergo an oxidation reaction to produce metal ions. These metal ions further undergo hydrolysis and polymerization reactions in water to form hydroxide flocs with flocculation effects, thereby adsorbing and removing pollutants in water. When treating wastewater containing heavy metal ions, aluminum or iron is usually used as the anode. The aluminum anode dissolves under the action of current to generate aluminum ions (Al 3+ ³⁺), and the aluminum ions undergo hydrolysis reactions to form aluminum hydroxide flocs. These flocs can adsorb heavy metal ions in the wastewater to form precipitates, thereby separating heavy metals from water.
[0003] The flocculating electrodes are fixed in the reservoir to decompose sewage. The existing electrodes cannot adjust their own height according to the depth of the sewage. During the electrolysis process, the electric field always concentrates in the peripheral area of the electrodes, and the sewage cannot be fully electrolyzed. Therefore, it is necessary to increase the power to expand the range of the electric field, resulting in an increase in power consumption. Moreover, the electrodes are soaked in sewage for a long time, which will cause a very thin hydrated gel layer to form on the sensitive membrane of the electrodes, hindering the progress of the electrochemical reaction, leading to electrode passivation, and further increasing the electrolysis energy consumption. Therefore, an electrocoagulation intelligent control system is proposed. Summary of the Utility Model
[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. In this part, as well as in the abstract and the title of the utility model of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this part, the abstract, and the title of the utility model, but such simplifications or omissions cannot be used to limit the scope of the utility model.
[0005] In view of the above problems existing in the existing electrocoagulation intelligent control system, the present utility model is proposed.
[0006] Therefore, the purpose of the present utility model is to provide an electrocoagulation intelligent control system, which is applicable to solving the problems that the existing electrodes cannot adjust their own height according to the depth of the sewage, and the electrodes are soaked in sewage for a long time, which will cause a very thin hydrated gel layer to form on the sensitive membrane of the electrodes, hindering the progress of the electrochemical reaction, leading to electrode passivation, and thus increasing the energy consumption.

[0026] Embodiment
[0027] Refer to Figure 1 - Figure 4 , which is an embodiment of the present utility model, provides an electrocoagulation intelligent control system, including: a flocculation unit 100 and a lifting unit 200;
[0028] Among them, the flocculation unit 100 includes a water storage tank 101 and an intelligent control cabinet 102 fixedly installed on one side of the water storage tank 101. A water inlet pipe 103 and a water outlet pipe 104 are fixedly connected to the same side of the water storage tank 101 respectively;
[0029] The lifting unit 200 includes a gantry 201 fixedly installed on the top of the water storage tank 101. An electric telescopic rod 202 is fixedly installed at the bottom of the gantry 201. The output end of the electric telescopic rod 202 is fixedly connected to a fixing plate 203. A plurality of electrode plates 204 are fixedly installed at the bottom of the fixing plate 203. A connecting rod 205 is fixedly connected to the top of the fixing plate 203. The bottom end of the connecting rod 205 is fixedly connected to a mounting plate 206. A mounting column is fixedly connected to the bottom of the mounting plate 206. A first pressure sensor 207 is fixedly installed at the bottom of the mounting column. A second pressure sensor 208 is fixedly installed at the bottom of the mounting plate 206. A floating assembly 209 for controlling the lifting of the electric telescopic rod 202 is arranged on the inner wall of the water storage tank 101.
[0030] The intelligent control cabinet 102 and the electrode plate 204 are both conventional technical means in the electrocoagulation equipment, and no more detailed explanations will be given here. Through the intelligent control cabinet 102, the lifting height of the electric telescopic rod 202 can be controlled, and by recording the height of the electric telescopic rod 202 descending, the water depth of the sewage can be calculated in combination with the depth of the water storage tank 101, so that the intelligent control cabinet 102 can adjust the voltage released by the electrode plate 204 to electrolyze the sewage with the best energy consumption, so as to flocculate the pollutants in the sewage into groups.
[0031] In addition, the floating assembly 209 includes a rectangular frame 2091 fixedly connected to the inner wall of the water storage tank 101. Opposite surfaces of the inner wall of the rectangular frame 2091 are respectively fixedly connected with T-shaped rods 2092. A floating plate 2093 is slidably arranged between the two T-shaped rods 2092. A pressure rod 2094 and an L-shaped floating plate 2095 are fixedly connected to the top of the floating plate 2093. A floating ball rod 2096 penetrates through the top of the L-shaped floating plate 2095. A turbidimeter 210 is fixedly installed on one side of the rectangular frame 2091. The floating plate 2093 is located inside the rectangular frame 2091, the pressure rod 2094 is directly below the first pressure sensor 207, and the floating ball rod 2096 is directly below the second pressure sensor 208.
[0032] Sewage is injected into the water storage tank 101 through the water inlet pipe 103. The rectangular frame 2091 is suspended on the inner wall of the water storage tank 101, and there is a distance between the rectangular frame 2091 and the bottom of the inner wall of the water storage tank 101, so that the sewage rises from the bottom of the rectangular frame 2091. While the sewage is rising, the floating plate 2093 contacts the sewage and moves upward by buoyancy. Through the two T-shaped rods 2092, the floating plate 2093 can be made to vertically lift and lower smoothly inside the rectangular frame 2091. The rectangular frame 2091 can also block the turbulent flow caused by the water injection of the water inlet pipe 103, so that the sewage inside the rectangular frame 2091 tends to be in a stable state;
[0033] Subsequently, the intelligent control cabinet 102 controls the electric telescopic rod 202 to drive the fixed plate 203 to descend. Both the first pressure sensor 207 and the second pressure sensor 208 are devices or apparatuses that can sense pressure signals and convert the pressure signals into available output electrical signals according to certain rules. The models of both the first pressure sensor 207 and the second pressure sensor 208 are RPT8114-A-05-0300-G(000), which can operate underwater. The height of the first pressure sensor 207 is lower than that of the second pressure sensor 208. When the first pressure sensor 207 contacts the pressure lever 2094, the first pressure sensor 207 senses the pressure and sends a signal to the intelligent control cabinet 102 to stop the descent of the electric telescopic rod 202. At this time, the electrode plate 204 is completely immersed in the sewage and hovers in the sewage. The intelligent control cabinet 102 calculates the depth of the sewage based on the length of the descent of the electric telescopic rod 202, thereby adjusting the voltage released by the electrode plate 204. When the water depth is shallow, the voltage decreases; when the water depth is high, the voltage increases. Compared with the traditional passive voltage regulation, the active voltage regulation can ensure that the electrode plate 204 is completely immersed in the sewage while also enabling the electrode plate 204 to always maintain the optimal height, so that the electrode plate 204 operates with the best energy consumption;
[0034] When the sewage rises and is higher than the upper surface of the floating plate 2093, the pressure lever 2094 still contacts the first pressure sensor 207, so that the electric telescopic rod 202 remains stationary. After the sewage continues to rise to a certain height, at this time, the electrode plate 204 is no longer in the optimal height and the optimal energy consumption range. The optimal energy consumption height of the rising sewage does not exceed the length of the float rod 2096. After the sewage rises to the upper surface of the floating plate 2093, the float rod 2096 rises by buoyancy, and then the top of the float rod 2096 contacts the second pressure sensor 208;
[0035] The second pressure sensor 208 senses the pressure and sends a signal to the intelligent control cabinet 102 to drive the electric telescopic rod 202 to rise. When the second pressure sensor 208 no longer contacts the float rod 2096, the electric telescopic rod 202 stops rising. The floating plate 2093 rises by buoyancy, and the electric telescopic rod 202 will descend again. When the first pressure sensor 207 contacts the pressure lever 2094 again, the electric telescopic rod 202 stops descending. Thus, the height of the electrode plate 204 can be automatically adjusted according to the height of the sewage. When the turbidimeter 210 detects that the pollutants are electrolyzed and flocculated, the turbidimeter 210 sends a signal to the intelligent control cabinet 102 to control the electric telescopic rod 202 to drive the electrode plate 204 to rise above the water surface. This can reduce the phenomenon that the surface of the electrode plate 204 forms a hydrated gel layer by the sewage, thereby reducing the power consumption caused by the erosion of the electrode plate 204 by the sewage and maintaining the good state of the electrode plate 204 for a long time.
[0036] Furthermore, L-shaped grooves 211 are symmetrically provided on opposite surfaces of the inner wall of the water tank 101, and a straight plate 212 is slidably provided between the two L-shaped grooves 211. A plurality of cleaning rods 213 are threadedly connected to one side of the straight plate 212. A square plate is fixedly connected to the inner wall of the water tank 101, and a rotating rod 214 is threadedly connected to the top of the square plate. The rotating rod 214 penetrates the square plate and contacts with the straight plate 212. A limiting plate 215 is fixedly connected to one side of the straight plate 212, and a circular through hole is provided on the top of the limiting plate 215.
[0037] During long-term use, contaminants will adhere to the surface of the electrode plate 204. The straight plate 212 is pushed along the two L-shaped grooves 211, so that the multiple cleaning rods 213 and the multiple electrode plates 204 are staggered. Then, the electric telescopic rod 202 is controlled by the intelligent control cabinet 102 to perform repeated lifting and lowering actions, so that the brush on the cleaning rod 213 can be used to clean the contaminants. The cleaning rod 213 can be disassembled and replaced through the thread.
[0038] The rotating rod 214 is used to press against one side of the I-shaped plate 212 to prevent the electrode plate 204 from sliding between the two L-shaped grooves 211 when cleaning the electrode plate 204. When the cleaning rod 213 has finished cleaning, the rotating rod 214 is rotated so that it no longer contacts the I-shaped plate 212, and the I-shaped plate 212 is slid so that the circular groove of the limiting plate 215 is located directly below the rotating rod 214. Then, the rotating rod 214 is rotated so that its bottom end passes through the circular groove to limit the I-shaped plate 212. At this time, the cleaning rod 213 is no longer located below the fixed plate 203, so that the fixed plate 203 can participate in the lifting movement.
[0039] During use, sewage is injected into the water storage tank 101 through the water inlet pipe 103, and then the intelligent control cabinet 102 controls the electric telescopic rod 202 to drive the fixed plate 203 to descend. When the first pressure sensor 207 contacts the pressure rod 2094, the electric telescopic rod 202 descends. At this time, the intelligent control cabinet 102 calculates the depth of the sewage by the length of the electric telescopic rod 202 that has been descended, thereby adjusting the voltage released by the electrode plate 204. When the sewage rises and is higher than the upper surface of the floating plate 2093, the float rod 2096 rises due to buoyancy, and then the top of the float rod 2096 contacts the second pressure sensor 208. At this time, the electric telescopic rod 202 rises. When the second pressure sensor 208 is no longer in contact with the float rod 2096;
[0040] Then the electric telescopic rod 202 will no longer rise and will descend again. When the first pressure sensor 207 contacts the pressure rod 2094 again, the electric telescopic rod 202 stops descending. Thus, the height of the electrode plate 204 can be automatically adjusted according to the height of the sewage. When the turbidimeter 210 detects that the pollutants are electrolyzed and flocculated, the turbidimeter 210 sends a signal to the intelligent control cabinet 102 to control the electric telescopic rod 202 to drive the electrode plate 204 to rise above the water surface. After flocculation, the sewage is discharged through the water outlet pipe 104. By pushing the one-word plate 212 along the two L-shaped grooves 211, the pollutants can be cleaned up by the brush on the cleaning rod 213. After cleaning, by sliding the one-word plate 212, and then rotating the rotating rod 214 so that its bottom end passes through the circular through groove of the limiting plate 215 to limit the one-word plate 212, and then the electrode plate 204 can work normally.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
