Description

Technical Field

[0001] This utility model is a wastewater electro-oxidation treatment device, belonging to the field of wastewater treatment. Background Technology

[0002] Electro-oxidation treatment of wastewater has advantages such as no secondary pollution, high energy efficiency, and simple electrolysis equipment and operation methods, and is widely used in the treatment of recalcitrant industrial wastewater.

[0003] In existing technologies, common wastewater electro-oxidation treatment devices require wastewater to be poured into the device before electricity is applied to allow the cathode and anode plates to electro-oxidize the wastewater. During electrolysis, a reduction reaction occurs on the surface of the cathode plate, forming precipitates with Ca2+ and Mg2+ in the water, resulting in scale buildup on the cathode plate surface. Therefore, some wastewater electro-oxidation treatment devices use a motor to drive a rotating brush to remove the scale from the cathode plate surface. However, due to the diverse impurities in the wastewater, the scale formed on the cathode plate surface varies in nature, and the fixed material of the rotating brush in the aforementioned devices makes it difficult to adjust the cleaning force of the brush for different types of scale (such as crystalline hard scale and organic slime), resulting in poor cleaning effect of the rotating brush. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wastewater electro-oxidation treatment device to solve the problems mentioned in the background art. Due to the diverse impurities in the wastewater, the scale formed on the cathode plate surface varies in nature, and the fixed material of the rotating brush makes it difficult to adjust the cleaning force of the rotating brush for different types of scale (such as crystalline hard scale and organic sludge), resulting in poor cleaning effect of the rotating brush.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater electro-oxidation treatment device, comprising a lower housing, an upper housing at the top of the lower housing, a plurality of cathode plates inside the lower housing, an anode plate located on the side of the cathode plates inside the lower housing, a support frame fixedly connected to the top of the upper housing, a cleaning motor fixedly connected to the top of the support frame, a first gear fixedly connected to the output end of the cleaning motor, a connecting frame rotatably connected inside the upper housing, a second gear fixedly connected to the surface of the connecting frame, a plurality of holding boxes below the connecting frame, a switching motor fixedly connected to the inner wall of the holding boxes, a switching cylinder fixedly connected to the output end of the switching motor, the switching cylinder being rotatably connected to the holding boxes, and a plurality of brush plates inside the switching cylinder.

[0006] Furthermore, the bottom end of the connecting frame is provided with several sliding grooves, the sliding grooves are T-shaped, and springs are fixedly connected to the inner wall of the sliding grooves. The springs are fixedly connected to the holding box, and the holding box is slidably connected to the sliding grooves.

[0007] Furthermore, a fixing bolt is inserted inside the upper housing, and a fixing nut is threaded onto the surface of the fixing bolt.

[0008] Furthermore, a locking bolt is inserted inside the brush plate, and the locking bolt is threadedly connected to the switching cylinder.

[0009] Furthermore, a pressure-dividing rod is fixedly connected to one side of the container, and one end of the pressure-dividing rod is arc-shaped.

[0010] Furthermore, a holding slot is provided above the slide groove in the connecting frame, and the holding slot is T-shaped.

[0011] Furthermore, both the cathode plate and the anode plate are cylindrical, and the cathode plate and the anode plate are alternately arranged inside the lower housing, with the cathode plate being the outermost layer. The bottom end of the lower housing is conical, and a solenoid valve is fixedly connected to the bottom surface of the lower housing.

[0012] The beneficial effects of this utility model are as follows: by switching the motor, the switching cylinder will rotate in the holding box, so that the appropriate brush plate can be selected according to the specific condition of the sewage or scale layer, thereby improving the descaling effect. Then, in conjunction with the support frame, cleaning motor, first gear, second gear, connecting frame and holding box, the brush plate will slide along the surface of the cathode plate, so that the surface of the cathode plate can be cleaned.

[0013] The use of fixing nuts and bolts facilitates maintenance of components located in the lower housing, while the use of locking bolts allows for the replacement of the brush plate, thereby further improving the descaling effect of the brush plate.

[0014] As the bristles on the surface of the brush plate wear down over time, the spring and slide will cause the brush plate to contact the cathode plate, thus ensuring that the brush plate can always maintain effective contact with the cathode plate, maintaining the cleaning ability of the brush plate, and avoiding the need for frequent replacement of the brush plate due to decreased cleaning effect. The pressure divider rod also prevents the brush plate from being damaged due to excessive spring force. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a wastewater electro-oxidation treatment device, including a lower shell 1, an upper shell 2 at the top of the lower shell 1, a plurality of cathode plates 3 inside the lower shell 1, an anode plate 4 located on the side of the cathode plate 3 inside the lower shell 1, a support frame 5 fixedly connected to the top of the upper shell 2, a cleaning motor 501 fixedly connected to the top of the support frame 5, a first gear 502 fixedly connected to the output end of the cleaning motor 501, a connecting frame 503 rotatably connected inside the upper shell 2, a second gear 504 fixedly connected to the surface of the connecting frame 503, a plurality of holding boxes 505 below the connecting frame 503, a switching motor 506 fixedly connected to the inner wall of the holding box 505, a switching cylinder 507 fixedly connected to the output end of the switching motor 506, the switching cylinder 507 and the holding box 505 are rotatably connected, and a plurality of brush plates 508 are arranged inside the switching cylinder 507.

[0023] By switching the motor 506, the switching cylinder 507 will rotate inside the container 505, allowing the appropriate brush plate 508 to be selected according to the specific condition of the sewage or scale layer, thereby improving the descaling effect. Then, in conjunction with the support frame 5, cleaning motor 501, first gear 502, second gear 504, connecting frame 503 and container 505, the brush plate 508 will slide along the surface of the cathode plate 3, thus cleaning the surface of the cathode plate 3.

[0024] Furthermore, both the cathode plate 3 and the anode plate 4 are cylindrical, and the cathode plate 3 and the anode plate 4 are alternately arranged inside the lower housing 1, with the cathode plate 3 being the outermost layer. The bottom end of the lower housing 1 is conical, and a solenoid valve 101 is fixedly connected to the bottom surface of the lower housing 1.

[0025] The bottom of the lower shell 1 is tapered, which can guide the treated wastewater inside it to the outside of the device, thereby helping to reduce the residual treated wastewater inside the lower shell 1.

[0026] Furthermore, a holding slot 5032 is provided inside the connecting frame 503 above the slide 5031, and the holding slot 5032 is T-shaped.

[0027] The cable for power supply can be stored in the holding slot 5032, which not only protects the cable, but also allows the cable to rotate synchronously with the connecting bracket 503 when it rotates, preventing the cable from coiling up.

[0028] Please see Figure 3 and Figure 4 The present invention provides a technical solution: the bottom end of the connecting frame 503 is provided with a plurality of sliding grooves 5031, the sliding grooves 5031 are T-shaped, and springs 509 are fixedly connected to the inner wall of the sliding grooves 5031. The springs 509 are fixedly connected to the holding box 505, and the holding box 505 is slidably connected to the sliding grooves 5031.

[0029] When the bristles on the surface of the brush plate 508 become shorter due to wear over time, the spring 509 and the slide groove 5031 will drive the brush plate 508 to contact the cathode plate 3, thereby ensuring that the brush plate 508 can always be in effective contact with the cathode plate 3, maintaining the cleaning ability of the brush plate 508, and avoiding the need to frequently replace the brush plate 508 due to the decline in cleaning effect.

[0030] Preferably, a pressure-dividing rod 511 is fixedly connected to one side of the container 505, and one end of the pressure-dividing rod 511 is arc-shaped.

[0031] The pressure-dividing rod 511 prevents damage to the brush plate 508 due to excessive force from the spring 509.

[0032] Please see Figures 1 to 4 The present invention provides a technical solution: a fixing bolt 201 is inserted inside the upper housing 2, a fixing nut 202 is threaded on the surface of the fixing bolt 201, a locking bolt 510 is inserted inside the brush plate 508, and the locking bolt 510 is threadedly connected to the switching cylinder 507.

[0033] The fixing nut 202 and fixing bolt 201 facilitate the maintenance of the components located in the lower housing 1, and the bristle plate 508 can be replaced with the locking bolt 510, thereby further improving the descaling effect of the bristle plate 508.

[0034] Specific implementation method: First, wastewater is poured into the device, and then electricity is turned on so that the cathode plate 3 and anode plate 4 electro-oxidize the wastewater. The treated wastewater will flow out from the bottom of the lower shell 1. During the electrolysis process, the surface of the cathode plate 3 will undergo a reduction reaction and form precipitates with Ca2+ and Mg2+ in the water, resulting in scale formation on the surface of the cathode plate 3. At this time, the switching motor 506 is started to drive the switching cylinder 507 to rotate in the holding box 505. The appropriate brush plate 508 can be selected according to the specific situation of the sewage or scale layer, thereby improving the descaling effect. Then, the cleaning motor 501 fixed at the top of the support frame 5 is started so that it drives the connecting frame 503 connected to the second gear 504 to rotate through the first gear 502, thereby driving several holding boxes 505 to rotate. Then, the brush plate 508 connected in the holding box 505 slides along the surface of the cathode plate 3 to clean the surface of the cathode plate 3.

[0035] Rotating the fixing nut 202 to disengage it from the fixing bolt 201 allows the upper housing 2 to be removed from the top of the lower housing 1, facilitating maintenance of the components located in the lower housing 1. Rotating the locking bolt 510 to disengage it from the switching cylinder 507 allows the brush plate 508 to be replaced, thereby further improving the descaling effect of the brush plate 508.

[0036] When the bristles on the surface of the brush plate 508 become shorter due to wear over time, the spring 509 will push the container 505 to slide along the groove 5031 opened at the bottom of the connecting frame 503 towards the cathode plate 3 until the brush plate 508 contacts the cathode plate 3. This ensures that the brush plate 508 can always be in effective contact with the cathode plate 3, maintains the cleaning ability of the brush plate 508, and avoids the need to frequently replace the brush plate 508 due to the decline in cleaning effect. The pressure dividing rod 511 prevents the brush plate 508 from being damaged due to excessive force of the spring 509.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
