Description

[0002] Electrocatalytic technology is a technology that uses active substances generated by interfacial electron gain and loss to degrade organic pollutants. Its main principle is to directly degrade organic matter in sewage through anode reaction. However, after long-term use of electrocatalytic oxidation equipment, a large amount of foreign matter and impurities are easily attached and accumulated on the surface of the electrode plate, which makes the electrocatalytic oxidation effect of the electrode plate worse and affects its electrocatalytic oxidation efficiency. Therefore, it is necessary to clean and maintain the electrode plate regularly to ensure its use effect.

[0003] The applicant disclosed an electrocatalytic oxidation sewage treatment equipment in the patent with publication number CN221940205U, including a tank body and a plurality of anode plates and cathode plates arranged vertically and at intervals in the tank body, wherein the plurality of anode plates and cathode plates are connected to an external power source through cables, and also includes a cleaning component, an adjusting component and a displacement component, wherein the cleaning component is arranged on the adjusting component, and the adjusting component is used to drive the cleaning component to move relative to the tank body; the adjusting component is arranged on the displacement component, and the displacement component is used to drive the adjusting component to move in a direction away from or close to the tank body. The utility model can automatically clean a plurality of electrode plates in the tank body through the cleaning component and the adjusting component, without the need for the staff to repeatedly disassemble and assemble the plurality of electrode plates, which not only simplifies the operation steps and reduces the labor intensity of the staff, but also shortens the cleaning and maintenance time and improves the work efficiency; the spatial position of the cleaning component and the adjusting component is changed by the displacement component, so that the electrode plates can be disassembled and replaced easily, which is conducive to maintenance.

The staff needs to wait for a long time for the equipment to complete the cleaning process, which affects the operating efficiency and the sewage treatment efficiency, and is inconvenient to use; at the same time, the electrocatalytic sewage treatment equipment with automatic electrode plate cleaning function in the prior art is usually only able to simply clean the motor plate, and cannot perform targeted cleaning according to different types of dirt (such as sticky substances, calcifications, etc.), so it is difficult to ensure the cleaning effect of the electrode plate, which reduces the cleaning quality of the electrode plate.

[0035] Embodiment 1:

[0036] The invention provides an electrocatalytic oxidation sewage treatment device.

[0037] In one embodiment of the present invention, an electrocatalytic oxidation sewage treatment device is used for pre-treating high-salt wastewater, including a tank body 1 and a plurality of electrode plates vertically and spaced apart in the tank body 1, wherein the plurality of electrode plates are connected to an external power source through cables, and further including a driving mechanism 2, a beam 3, an adjusting mechanism 4 and a plurality of cleaning mechanisms 5, wherein the driving mechanism 2 is arranged at the top of the tank body 1 and is used to drive the beam 3 to move, the beam 3 is movably mounted on the driving mechanism 2, and the plurality of cleaning mechanisms 5 are evenly and spaced apart along the extension direction of the beam 3;

[0038] The cleaning mechanisms 5 each include a fixed seat 6, a connecting rod 7, an adjusting assembly, two movable seats 8 and a plurality of cleaning assemblies for cleaning the electrode plates. The fixed seat 6 is mounted on the beam 3 in a limited and movable manner. The fixed seats 6 are detachably connected to the connecting rod 7 so that the fixed seats 6 are transmission-connected to the power output end of the adjusting mechanism 4 through the connecting rod 7; the adjusting assembly is arranged on the fixed seat 6 and is used to drive the two movable seats 8 to move closer to or away from each other. Cleaning assemblies are respectively arranged on the two movable seats 8, and the two movable seats 8 are respectively located on both sides of an electrode plate, so that the movable seats 8 and the electrode plate are alternately arranged in sequence along the extension direction of the beam 3.

[0039] Specifically, Figures 1 to 7As shown, in an electrocatalytic oxidation sewage treatment device of the present invention, high-salt wastewater can be placed through the cell body 1. Since a plurality of electrode plates are vertically arranged in the cell body 1, the plurality of electrode plates are respectively a plurality of anode plates and cathode plates, and the plurality of anode plates and cathode plates are arranged in an alternating manner in the left and right directions, and the plurality of anode plates and cathode plates are connected to an external power source through cables, so that the high-salt wastewater can be electrocatalytically treated and the degradation of organic pollutants in the high-salt wastewater can be achieved. Furthermore, since the crossbeam 3 is movably mounted on the driving mechanism 2, the plurality of cleaning mechanisms 5 are evenly and spacedly arranged along the extension direction of the crossbeam 3, and the crossbeam 3 and the driving mechanism 2 can be movably mounted in a rotating clamping manner, thereby enabling the plurality of cleaning mechanisms 5 on the crossbeam 3 to rotate relative to the cell body 1 and the driving mechanism 2. When the electrode plate needs to be cleaned, the staff can rotate the beam 3 to allow several cleaning mechanisms 5 to be transferred into the pool body 1. After the beam 3 is rotated into place, it is locked and limited. At this time, the staff starts the driving mechanism 2, and the driving mechanism 2 drives the beam 3 to move in the front and rear directions, thereby realizing the synchronous cleaning of several motor plates by several cleaning mechanisms 5, and the structural design is simple and reasonable.

[0040] It can be understood that, since the fixed seats 6 in the cleaning mechanisms 5 are all installed on the beam 3 in a limited and movable manner, and the fixed seats 6 are all detachably connected to the connecting rod 7, by connecting the connecting rod 7 to the power output end of the adjusting mechanism 4, the adjusting mechanism 4 can drive the connecting rod 7 and the fixed seats 6 to move relative to the beam 3 in the left and right direction. Further, when the cleaning mechanisms 5 are transferred into the pool body 1 for clamping and limiting, the adjusting mechanism 4 can drive the connecting rod 7 and the fixed seats 6 to move to the left relative to the beam 3, and since the adjusting component in the cleaning mechanism 5 is arranged on the fixed seat 6 and is used to drive the two movable seats 8 to move closer to or away from each other, that is, the two movable seats 8 are arranged on the fixed seat 6 through the adjusting component, and the two movable seats 8 are respectively provided with cleaning components, and the two cleaning components are respectively located on both sides of an electrode plate, so that the movable seats 8 and the electrode plate can be arranged alternately in sequence along the left and right directions. When the adjusting mechanism 4 drives the plurality of fixed seats 6 to move to the left, the cleaning components installed on the movable seat 8 on the right side of the fixed seat 6 can abut against the right side wall of the electrode plate, that is, at this time, the plurality of cleaning components can respectively and one-to-one correspond to the right side walls of the plurality of electrode plates for synchronous cleaning; similarly, when the adjusting mechanism 4 drives the plurality of fixed seats 6 to move to the right, the cleaning components installed on the movable seat 8 on the left side of the fixed seat 6 can abut against the left side wall of the electrode plate, that is, at this time, the plurality of cleaning components can respectively and one-to-one correspond to the left side walls of the plurality of electrode plates for synchronous cleaning. It can be seen that the present invention can enable the plurality of cleaning mechanisms 5 to automatically and synchronously clean the plurality of electrode plates through the coordinated use of the adjusting mechanism 4 and the driving mechanism 2, without the need for the staff to wait for a long time for the equipment to complete the cleaning process, which not only greatly improves the cleaning efficiency, but also shortens the cleaning and maintenance time of the equipment, is conducive to maintaining the long-term operation of the equipment, and improves the operating efficiency and the sewage treatment efficiency, and is reliable to use.

[0041] It should be noted that, since the present invention is a further improvement and optimization made by the applicant based on an electrocatalytic oxidation sewage treatment device of CN221940205U, no changes are made to the installation method of the plurality of electrode plates, that is, the present invention can still adjust the position of the anode plate according to the actual size and area demarcation of the cell body 1, so that the staff can increase or decrease the number of electrode plates and flexibly adjust the spacing between the electrode plates according to the different water quality components of the wastewater, thereby reducing the operating energy consumption of the equipment and improving the electrolysis efficiency. Since the fixed seat 6 is installed on the beam 3 in a limited and movable manner, the fixed seat 6 and the beam 3 can be installed in a limited and movable manner by a threaded connection, which makes it easy to adjust the installation position of the fixed seat 6 according to the change in the spacing between several electrode plates, so as to meet the requirement that several cleaning components can clean several electrode plates, and the use is reliable; at the same time, the adjustment component in the cleaning mechanism 5 can drive the two movable seats 8 to move closer to or away from each other, and the adjustment component can be adopted as a gear rack in the prior art, that is, the two movable seats 8 are respectively clamped on the fixed seat 6 in a limited and movable manner along the left and right directions, and at the same time, the two movable seats 8 are respectively installed with racks meshing with gears, and the two movable seats 8 can be driven to move closer to or away from each other by rotating the gear, so that the distance between the cleaning components on the two movable seats 8 can be shortened or increased, and the spacing between two adjacent electrode plates can be adapted, so that the installation position of the cleaning component can be fine-tuned for a second time, so as to achieve precise alignment between the cleaning component and the electrode plate, thereby improving the cleaning efficiency and quality, and reducing the risk of electrode plate damage caused by improper gap between the cleaning component and the electrode plate.

[0042] It is worth noting that the cleaning component can be a brush, a scraper, and a high-pressure nozzle connected to an external liquid supply system. It can be understood that when the driving mechanism 2 drives the cleaning component to move, the brush can clean the general dirt attached to the surface of the electrode plate; the scraper can scrape off the calcification or stubborn stains sticking to the surface of the electrode plate, and the high-pressure nozzle can flush the sticky dirt that is difficult to remove with a brush, so that the electrode plate can be cleaned in a targeted manner according to the different types of dirt (such as sticky substances, calcifications, etc.), ensuring the cleanliness of the surface of the electrode plate, effectively improving the cleaning effect and quality, and helping to improve the effect of electrocatalytic oxidation and extend the service life of the electrode plate. In addition, the high-pressure nozzle can also be used to rinse the brush and scraper, thereby realizing the self-cleaning function of the cleaning component, eliminating the need for the staff to manually clean the cleaning components such as the brush and scraper, reducing the labor intensity of the staff, improving the operating efficiency of the equipment, and being easy to use.

[0043] In addition, the electrocatalytic oxidation sewage treatment equipment of the present invention also includes a control system, which is used to control the regulating mechanism 4 and the driving mechanism 2 to drive the cleaning mechanisms 5 to clean the electrode plates; at the same time, the foreign matter and impurities cleaned from the electrode plates can be discharged through a screw conveyor arranged at the bottom of the cell body 1, and the precipitates continuously generated during the electrocatalytic process can also be discharged synchronously through the screw conveyor to avoid the precipitates from adhering to the electrode plates or the inner wall of the cell body 1. The control system and the screw conveyor are mature existing technologies and will not be described in detail here. The present invention is only aimed at solving the problems of low cleaning efficiency, difficulty in ensuring the cleaning effect of the electrode plates, and reduced cleaning quality of the electrode plates in the existing electrocatalytic oxidation sewage treatment equipment.

[0044] In one embodiment, a slide rail is formed on the bottom surface of the fixed seat 6, a slide groove for sliding contact with the slide rail is formed on the movable seat 8, and the adjustment assembly includes an adjustment rod 9, and two sections of threads with opposite rotation directions are formed on the adjustment rod 9 along its extension direction. The two movable seats 8 are respectively threadedly connected with the adjustment rod 9 to move closer to or away from each other through the adjustment rod 9, and locking members are detachably installed at both ends of the adjustment rod 9. Specifically, as Figures 5 to 7 As shown, the protrusion 11 formed on the bottom surface of the fixed seat 6 and the sliding groove provided on the movable seat 8 are in sliding contact, which not only improves the connection stability between the fixed seat 6 and the movable seat 8, but also ensures that the movable seat 8 can move smoothly and accurately along the extension direction of the protrusion 11 under the action of the adjustment component, and the structural design is simple and reasonable. Furthermore, since the adjustment rod 9 is formed with two sections of threads with opposite rotation directions along its extension direction, and the two movable seats 8 are respectively threadedly connected with the adjustment rod 9, the staff can realize the precise adjustment of the positions of the two movable seats 8 by rotating the adjustment rod 9, and the operation is simple and convenient; at the same time, it is obvious that the sliding cooperation between the protrusion 11 and the sliding groove, the threaded connection between the movable seat 8 and the adjustment rod 9, and the installation of the locking member together constitute a stable and reliable transmission adjustment system, thereby ensuring the stability and reliability of the equipment during long-term operation.

[0045] In one embodiment, the cross beam 3 is provided with a plurality of limit grooves 10 along its circumference, and the plurality of limit grooves 10 extend toward both ends of the cross beam 3. The fixing seat 6 is provided with a groove for the cross beam 3 to extend into, and a plurality of protrusions 11 are formed on the groove wall of the groove, and the plurality of protrusions 11 are respectively and one by one correspondingly slidably contacted with the plurality of limit grooves 10. Specifically, Figures 5 to 7As shown, multi-point limiting of the fixing seat 6 can be achieved through the sliding contact cooperation between a plurality of protrusions 11 and a plurality of limiting grooves 10, which not only limits the displacement and shaking of the fixing seat 6 during the movement and adjustment process on the beam 3, but also improves the installation stability of the fixing seat 6 on the beam 3; at the same time, when it is necessary to adjust the installation position of the fixing seat 6 to adapt to the spacing between a plurality of electrode plates, it is sufficient to slide the corresponding fixing seat 6 in the left and right directions. After the fixing seat 6 slides into place, it can be limited and fixed by screw connection or clamping, which is simple and convenient to operate.

[0046] In one embodiment, the crossbeam 3 is provided with a through groove along its extension direction, and a through hole is provided on the fixed seat 6. The cleaning assembly includes a mounting rod 12, a flushing pipe 13, a brush strip 14 and a scraper 15. The mounting rod 12 and the flushing pipe 13 are vertically arranged on the movable seat 8, and one end of the mounting rod 12 and the flushing pipe 13 are detachably connected to the movable seat 8. Brush strips 14 are respectively provided on both sides of the mounting rod 12 facing the electrode plate. The flushing pipe 13 is connected to the external liquid supply system through an infusion pipe 16 passing through the through hole and the through groove. Scrapers 15 are respectively provided on both sides of the flushing pipe 13 facing the width direction of the pool body 1, and a plurality of liquid outlet holes 17 are provided on both sides of the flushing pipe 13 facing the electrode plate. The plurality of liquid outlet holes 17 are evenly and spacedly arranged along the extension direction of the flushing pipe 13.

[0047] Specifically, Figure 6 and Figure 7 As shown, since the mounting rod 12 and the flushing tube 13 are vertically arranged on the movable seat 8, the mounting rod 12 and the flushing tube 13 can effectively contact the surface of the electrode plate, thereby improving the cleaning effect; at the same time, the mounting rod 12 and the flushing tube 13 can be detachably connected to the movable seat 8 by threaded connection or ferrule clamping, thereby facilitating the disassembly and assembly of the mounting rod 12 and the flushing tube 13, which is beneficial for subsequent maintenance and replacement. Furthermore, by providing a through groove in the left and right directions on the crossbeam 3, a convenient installation channel can be provided for the infusion tube 16 to ensure that the infusion tube 16 can be smoothly connected to the flushing tube 13, which is beneficial for supplying liquid to the flushing tube 13, and the structural design is simple and reasonable; at the same time, since the flushing tube 13 is provided with a plurality of liquid outlets 17 on both sides facing the electrode plate, it is possible to achieve uniform multi-point flushing of the electrode plate, reduce the flushing dead angle, improve the cleaning effect, and be reliable in use. It should be noted that, through the combined use of the brush strip 14 and the scraper 15, and the uniform spraying of the flushing pipe 13, different types of dirt and sediment on the surface of the electrode plate can be effectively removed, which not only improves the operating efficiency and electrocatalytic oxidation effect of the equipment, but also prolongs the service life of the electrode plate. In addition, the brush strip 14 and the scraper 15 can also be flushed through the flushing pipe 13 to realize the self-cleaning function of the cleaning component, which is more convenient to use.

[0048] In one embodiment, the adjustment mechanism 4 includes a first driving member 18, a support seat 19 and a connecting seat 20, the connecting seat 20 is detachably connected to the connecting rod 7, the support seat 19 is arranged on the connecting seat 20, the first driving member 18 is arranged on the crossbeam 3, and the power output end of the first driving member 18 is detachably connected to the support seat 19, so as to drive the plurality of cleaning mechanisms 5 to move relative to the crossbeam 3 through the first driving member 18. Specifically, Figure 1 and Figure 5 As shown, the first driving member 18 can be a linear reciprocating driving device such as a cylinder or a hydraulic cylinder in the prior art. At the same time, the power output end of the first driving member 18 is detachably connected to the support seat 19, and the support seat 19 is arranged on the connecting seat 20, and the connecting seat 20 is detachably connected to the connecting rod 7, so that the first driving member 18 can drive a number of cleaning mechanisms 5 to move relative to the crossbeam 3 along the left and right directions through the connecting rod 7, so that a number of cleaning components can clean the corresponding electrode plates. The structural design is ingenious and reasonable, and there is no need for the staff to manually adjust the number of cleaning mechanisms 5 in sequence, which simplifies the operation steps and makes it more convenient to use. In addition, it is worth noting that the installation method of the first driving member 18 and the crossbeam 3, the detachable connection method of the power output end of the first driving member 18 and the support seat 19, the installation method of the support seat 19 and the connecting seat 20, and the detachable connection method of the connecting seat 20 and the connecting rod 7 can all be threaded, thereby facilitating the disassembly and replacement of the adjustment mechanism 4 and its components, which is conducive to maintenance.

Specifically, as Figures 1 to 3As shown, the second driving member 21 can be an electric motor, hydraulic cylinder or pneumatic cylinder in the prior art, so that the second driving member 21 can drive any slide 23 to move along the front-back direction on the guide rail 22, and the structural design is simple and reasonable. Further, since the two sliding components are respectively arranged on both sides of the cell body 1, and the two ends of the beam 3 are respectively connected to the two slides 23 for rotation, the second driving member 21 can synchronously drive the beam 3 and the plurality of cleaning mechanisms 5 to move along the front-back direction, and thereby the plurality of cleaning mechanisms 5 can clean the dirt and impurities on the surface of the electrode plate. It can be understood that since the two ends of the beam 3 are respectively connected to the two slides 23 for rotation, when there is no need to clean the electrode plate, the staff can rotate the beam 3 and make the plurality of cleaning mechanisms 5 extend out of the cell body 1, and after rotating in place, the beam 3 is limited by threaded connection or clamping, thereby preventing the plurality of cleaning mechanisms 5 from affecting the normal operation of the equipment, and the use is reliable.

[0050] In one embodiment, one end of the cross beam 3 away from the second driving member 21 passes through a slide seat 23 and is detachably mounted with a handle. Figure 1 and Figure 2 As shown, the detachable installation method of the handlebar and the cross beam 3 can be threaded connection, which not only facilitates the disassembly and assembly of the handlebar, but also helps the staff to rotate the cross beam 3 to clean the electrode plate through a plurality of cleaning mechanisms 5, and the operation is convenient.

[0051] In one embodiment, a positioning seat 24 is provided on the cell body 1 at a position corresponding to the end of the guide rail 22, and a buffer member 25 is provided on the side of the positioning seat 24 facing the slide seat 23. Figure 1 and Figure 2 As shown, by providing a positioning seat 24 at the end of the guide rail 22 on the cell body 1, the slide 23 can be effectively prevented from sliding out of the guide rail 22. Furthermore, the buffer 25 can be a flexible gasket in the prior art, so as to absorb the impact and vibration generated when the slide 23 abuts against the positioning seat 24, prevent the cleaning mechanisms 5 from knocking or pushing the electrode plate to cause deformation or damage to the electrode plate, and improve the stability and reliability of the operation of the electrocatalytic oxidation device.

[0052] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
