[0002] Wastewater treatment is the process of purifying wastewater to meet the required water quality for discharge into a water body or reuse. Nitrogen and phosphorus in water are the primary contributors to eutrophication. Nitrogen in water primarily originates from wastewater discharged into the water. Therefore, removing nitrogen from wastewater is a crucial step in improving the water environment. Denitrification of wastewater can be achieved through adsorption on electrode surfaces.

[0003] For example, the utility model with application number CN202221207630.2 discloses an electrochemical synchronous denitrification and dephosphorization device. This utility model has the advantages of being easy to disassemble and replace the electrode plates and having a pre-filtration function. It solves the problem that the existing electrochemical synchronous denitrification and dephosphorization devices usually do not have a pre-filtration function during use, resulting in the inability to pre-filter the larger impurities contained in the sewage, thereby affecting the subsequent denitrification and dephosphorization effects. In addition, due to the single structure, it is not convenient for users to quickly disassemble and replace the electrode plates, which reduces the applicability of the electrochemical synchronous denitrification and dephosphorization device. However, impurities in sewage often clog the filter screen, and it is often necessary to stop the machine for a period of time to clean and maintain it. However, manual operation is more troublesome and inconvenient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an electric adsorption sewage deep denitrification device is proposed. Utility Model Content

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2As shown, an electric adsorption sewage deep denitrification device includes a denitrification box 1 and a cleaning component 6. A metal electrode plate 3 is installed between the two sides of the interior of the denitrification box 1, and the bottom end of the denitrification box 1 is connected to a drain pipe 2. A bracket 4 is connected to the upper right side of the denitrification box 1, and an auxiliary component 5 is installed on the right side of the rear end of the bracket 4. The bracket 4 accounts for one-sixth of the height of the denitrification box 1. There are two metal electrode plates 3. The cleaning component 6 is arranged at the front end of the denitrification box 1 and the bracket 4, and the cleaning component 6 includes a shell 601, a drive motor 602, a first gear 603, a second gear 604, a first transmission shaft 605, a third gear 606, a fourth gear 607, a second transmission shaft 608, a fifth gear 609, a rack 610 and a guide seat 611. The drive motor 602 is installed at the top of the interior of the shell 601, and the output shaft of the drive motor 602 is connected to the first gear 603. The first gear A second gear 604 and a fourth gear 607 are respectively provided on both sides of 603, and a first transmission shaft 605 is passed through the middle of the second gear 604, and the outside of the first transmission shaft 605 is connected to the third gear 606, and a second transmission shaft 608 is passed through the middle of the fourth gear 607, and the outside of the second transmission shaft 608 is connected to the fifth gear 609, and a rack 610 is provided between the third gear 606 and the fifth gear 609, and guide seats 611 are placed on both sides of the rack 610, and a cleaning brush 612 is connected to the rear end of the rack 610, the first transmission shaft 605 and the second transmission shaft 608 are both rotatably connected to the outer shell 601, the outer diameters of the first gear 603, the second gear 604 and the fourth gear 607 are consistent, the outer diameters of the third gear 606 and the fifth gear 609 are consistent, the outer shell 601 and the guide seat 611 are fixedly connected, and the front end of the outer shell 601 is provided with an opening.

[0023] The specific operation is as follows: the output shaft of the driving motor 602 drives the first gear 603 to rotate, and the first gear 603 drives the second gear 604 and the fourth gear 607 to rotate, so that the third gear 606 on the first transmission shaft 605 and the fifth gear 609 on the second transmission shaft 608 rotate. At this time, the third gear 606 and the fifth gear 609 are intermittently engaged with the rack 610 for transmission, so that the cleaning brush 612 is driven by the rack 610 and guided by the guide seat 611 to move back and forth to brush and clean the filter screen 507, eliminating the physical exertion of manual cleaning.

[0024] like Figure 1 and Figure 3As shown, the auxiliary component 5 includes a servo motor 501, a forward and reverse screw 502 and a screw nut 503, and the output end of the servo motor 501 passes through the rear end of the bracket 4 and is connected to the forward and reverse screw 502, and the outside of the forward and reverse screw 502 is connected to the screw nut 503, the auxiliary component 5 also includes a fixed block 504 and a swing arm 505, and a fixed block 504 is provided on the left side of the screw nut 503, and the top of the fixed block 504 is connected to the swing arm 505 through a rotating shaft, the auxiliary component 5 also includes a frame 506 and a filter 507, and the other end of the swing arm 505 is connected to the frame 506 through a rotating shaft, and a filter 507 is provided at the opening of the frame 506, and a cleaning brush 612 is provided at the bottom end of the filter 507.

[0025] The specific operation is as follows: the servo motor 501 drives the forward and reverse screws 502 to rotate, and the screw nut 503 drives the fixed block 504 to make a linear displacement toward or away from the outside of the forward and reverse screws 502, causing the swing arm 505 to rotate and make the frame 506 and the filter 507 make a linear displacement to the left or right, so as to facilitate the cleaning and maintenance of the blocked filter 507.

[0026] In summary, when the electric adsorption sewage deep denitrification device is used, the servo motor 501 is first operated to drive the forward and reverse threaded screws 502 to rotate, and the screw nut 503 drives the fixed block 504 to make a linear displacement relative to the outside of the forward and reverse threaded screws 502, so that the swing arm 505 on the fixed block 504 rotates and drives the frame 506 and the filter screen 507 to make a linear displacement toward the right opening of the denitrification box 1, until the frame 506 extends into the denitrification box 1 from the opening on the upper right side of the denitrification box 1;

[0027] When the interior of the denitrification box 1 is divided into two upper and lower cavities by the filter 507, sewage is transported into the denitrification box 1 through an external water supply pipe, so that larger impurities contained in the sewage are intercepted by the filter 507 and remain in the upper cavity, while qualified sewage remains in the lower cavity. At this time, power is turned on to perform electrochemical denitrification and dephosphorization under the action of the metal electrode plate 3. After the treatment is completed, the sewage is discharged from the drain pipe 2. Since the impurities in the sewage are removed in advance, the impurities are prevented from affecting the denitrification effect, thereby ensuring the denitrification efficiency;

[0028] When the filter screen 507 is clogged and needs to be cleaned and maintained, the servo motor 501 and the drive motor 602 are operated at the same time. The servo motor 501 drives the positive and negative screw rods 502 to rotate, and the screw nut 503 drives the fixed block 504 to make a linear displacement in the opposite direction with respect to the outside of the positive and negative screw rods 502, causing the swing arm 505 to rotate and drive the frame 506 and the filter screen 507 to make a linear displacement in the direction away from the right opening of the denitrification box 1, and the output shaft of the drive motor 602 drives the first gear 603 to rotate, and the first gear 603 drives the second gear 604 and the fourth gear 607 respectively. The wheel 607 drives the third gear 606 on the first transmission shaft 605 and the fifth gear 609 on the second transmission shaft 608 to rotate, so that the third gear 606 and the fifth gear 609 intermittently mesh with the rack 610 for transmission. The cleaning brush 612 is driven by the rack 610 and guided by the guide seat 611 to move back and forth against the filter 507 to brush and clean it. Since the filter 507 moves linearly to the right and the cleaning brush 612 moves back and forth synchronously, the filter 507 is fully cleaned, which replaces manual operation, reduces difficulty and improves cleaning efficiency.
