[0002] Electrocoagulation treatment is to quickly settle solid particles and suspended matter through electrochemical methods, thereby achieving rapid purification and treatment of wastewater. In the electrocoagulation process, wastewater passes through an electrolytic cell, and an appropriate amount of flocculant and polar gas generated by electrolysis in the electrolytic cell are added. The suspended matter and particles in the wastewater are precipitated and removed by the combined action of the flocculant and polar gas.
[0003] The prior art installs multiple pole plates in an electrolytic cell. When wastewater passes through the electrolytic cell, an electric field is generated between the pole plates, causing the charged particles in the wastewater to migrate, aggregate and precipitate under the action of the electric field, so that small particles of impurities are aggregated into large particles of impurities for easy cleaning. However, the impurities in the wastewater in the electrolytic cell cannot be completely aggregated and flocculated when passing through the middle of the pole plates, and the effect of removing impurities from the wastewater is not ideal. Therefore, an electronic flocculator for coal-containing wastewater that can efficiently flocculate wastewater is needed.
[0004] In view of this, the utility model provides an electronic flocculator for coal-containing wastewater. Utility Model Content

At the same time, the shear force generated by the rotation of the stirring rod acts on the surface of the circular plate to flush the dirt generated by the electric flocculation on the circular plate, effectively avoiding the occurrence of scaling problems on the circular plate.

[0008] As a further improvement of the technical solution, a water retaining plate is installed above the water inlet on the inner wall of the water inlet tank body to prevent the incoming water from flowing, and a high-frequency pulse automatic reversing battery is arranged outside the water inlet tank body to energize the circular plates.

The conductive plate 1 is connected to the circular plates arranged in odd numbers through the connecting block, and the conductive plate 2 is connected to the circular plates arranged in even numbers through the connecting block.
[0010] As a further improvement of the technical solution, conductive columns 1 and 2 are fixedly installed on the top of the conductive plate 1 and the conductive plate 2 and penetrate the outside of the water inlet tank body. The conductive columns 1 and 2 are electrically connected to the inside of the high-frequency pulse automatic commutation battery.

[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the electronic flocculator for coal-containing wastewater, wastewater enters the interior of the water inlet tank, spreads from the leak in the middle of the water retaining plate to the middle of the multi-layer circular electrode plates, and performs an efficient electric flocculation reaction. At the same time, the rotating rod drives the stirring rod to rotate, thereby accelerating the flocculation reaction efficiency in the wastewater and pushing the formed flocculated particles out of the middle of the circular electrode plates to avoid accumulation on the surface of the circular electrode plates, so that the flocculated particles can float to the water outlet following the bubbles and flow out, thereby achieving an efficient electric flocculation reaction effect on the wastewater.

DETAILED DESCRIPTION
[0021] By installing multiple plates in the electrolytic cell, wastewater passes through the electrolytic cell, and an electric field is generated between the plates, causing the charged particles in the wastewater to migrate, aggregate and precipitate under the action of the electric field, so that small particles of impurities are aggregated into large particles of impurities for easy cleaning. However, the wastewater in the electrolytic cell cannot completely aggregate and flocculate the impurities in the wastewater when passing through the middle of the plates, and the effect of removing impurities from the wastewater is not ideal. Therefore, an electronic flocculator for coal-containing wastewater that can efficiently flocculate the wastewater is needed.
[0022] like Figure 1-4 As shown, the device comprises a water inlet tank body 1, the bottom and top of the outer surface of the water inlet tank body 1 are respectively provided with a water inlet 2 and a water outlet 3, a plurality of circular plates 4 for flocculating wastewater are installed inside the water inlet tank body 1, a connecting assembly 5 for connecting the circular plates 4 is arranged outside the plurality of circular plates 4, and a stirring assembly 6 for stirring wastewater is arranged in the middle of the plurality of circular plates 4;
[0023] First, the specific structure of the connection assembly 5 is disclosed. The connection assembly 5 includes a conductive plate 1 501 and a conductive plate 2 502 arranged on the inner wall of the water inlet tank body 1. The outer surfaces of the conductive plate 1 501 and the conductive plate 2 502 are fixedly installed with a connection block 503. The conductive plate 1 501 is connected to the circular plates 4 arranged in odd numbers through the connection block 503, and the conductive plate 2 502 is connected to the circular plates 4 arranged in even numbers through the connection block 503. The tops of the conductive plates 1 501 and the conductive plates 2 502 are fixedly installed with conductive posts 1 7 and conductive posts 2 8 that penetrate the outside of the water inlet tank body 1. The conductive posts 1 7 and conductive posts 2 8 are electrically connected to the inside of the high-frequency pulse automatic commutation battery 12.
[0024] A water retaining plate 11 is installed above the water inlet 2 on the inner wall of the water inlet tank body 1 to prevent the incoming water from flowing. A high-frequency pulse automatic reversing battery 12 is arranged outside the water inlet tank body 1 to energize the circular plate 4.
[0025] The improvement of this embodiment is that when purifying coal-containing wastewater, the wastewater enters the interior of the water inlet tank 1 from the water inlet 2, and spreads upward from the leak in the middle of the water retaining plate 11 to the middle of the circular electrode plate 4. At the same time, the high-frequency pulse automatic reversing battery 12 energizes the conductive column 1 7 and the conductive column 2 8, so that the connected conductive plate 1 501 and the conductive plate 2 502 energize the circular electrode plate 4, so that the circular electrode plate 4 undergoes an electrochemical reaction, dissolves aluminum and iron ions, and hydrolyzes and flocculates with the impurity particles in the wastewater. There are multiple circular electrode plates 4, so that the wastewater can spread to the middle of each layer of circular electrode plates 4 to undergo flocculation reaction, and the reaction to the particulate impurities in the wastewater is more thorough, thereby achieving the effect of efficiently performing flocculation reaction on the particulate impurities in the wastewater, and solving the problem of unsatisfactory wastewater reaction treatment of particulate impurities in the prior art.
[0026] Due to the problem in the prior art that the flocculation of the reaction will precipitate onto the circular electrode plate 4, Figure 4 A second embodiment of the present utility model is shown.
[0027] The specific structure of the stirring assembly 6 is disclosed again. The stirring assembly 6 includes a driving motor 601 installed on the top of the water inlet tank body 1. The output shaft of the driving motor 601 is equipped with a rotating rod 602 that penetrates into the water inlet tank body 1. The outer surface of the rotating rod 602 is equipped with a stirring rod 603 in the middle of the adjacent circular pole plates 4.
[0028] The improvement of this embodiment lies in that: the rotating rod 602 penetrates the interior of the water inlet tank body 1 and the circular electrode plate 4, and the driving motor 601 can drive the rotating rod 602 to rotate in the middle of the circular electrode plate 4, so that the stirring rod 603 can rotate in the middle of the adjacent circular electrode plate 4, stirring the wastewater in real time, which can greatly improve the efficiency of the electric flocculation of wastewater particle impurities. At the same time, the shear force generated by the rotation of the stirring rod 603 acts on the surface of the circular electrode plate 4 to flush the dirt generated by the electric flocculation on the circular electrode plate 4, effectively avoiding the occurrence of scaling problems on the circular electrode plate 4, and hydrogen and oxygen are respectively precipitated during the electrolysis process of the circular electrode plate 4, floating upward in the form of highly dispersed tiny bubbles, and the stirring rod 603 can push the formed floccules out of the middle of the circular electrode plate 4, so that it floats to the top of the water surface inside the water inlet tank body 1 with the bubbles and is discharged from the water outlet 3.
[0029] In summary, the working principle of this solution is as follows:
[0030] Wastewater enters the interior of the water inlet tank 1, spreads from the leak in the middle of the water retaining disk 11 to the middle of the multi-layer circular electrode plate 4, and undergoes an efficient electric flocculation reaction. At the same time, the rotating rod 602 drives the stirring rod 603 to rotate, thereby accelerating the flocculation reaction efficiency in the wastewater and pushing the formed flocculated particles out of the middle of the circular electrode plate 4 to avoid accumulation on the surface of the circular electrode plate 4, so that the flocculated particles can float to the water outlet 3 with the bubbles to flow out, thereby achieving an efficient electric flocculation reaction effect on the wastewater.
