Description

Technical Field

[0001] This utility model relates to the field of electrocatalytic oxidation technology, specifically a multi-stage electrocatalytic oxidation degradation device. Background Technology

[0002] Wastewater treatment has always been an important research topic. Electrocatalytic oxidation degradation technology, as an efficient and environmentally friendly treatment method, has received widespread attention. This technology uses electrocatalysis to degrade pollutants into harmless substances by setting up an anode and a cathode in an electrolytic cell, thereby achieving the purpose of purifying water quality.

[0003] Chinese patent CN221701230U discloses an electrocatalytic oxidation degradation tank, pointing out that in current wastewater purification processes using electrocatalytic oxidation technology, the anode and cathode electrodes are mostly arranged in an alternating manner. The electrode plates are fixed relative to the degradation tank after arrangement, resulting in a fixed distance between the anode and cathode. This makes it impossible to adjust the electrode plate spacing according to the concentration and type of wastewater, thus reducing the efficiency of wastewater purification. The aforementioned patent addresses this by incorporating a rotating component within the device to adjust the spacing of the electrocatalytic components.

[0004] However, the drawback of the aforementioned patent is that although the electrocatalytic component is controlled by the rotating assembly, the structural limitations of the connecting rod make it inconvenient for operators to clean and maintain the internal electrocatalytic component, and also inconvenient to disassemble it. Over long-term use, the metal oxide passivation layer, organic polymers, inorganic scale, suspended solids and other substances deposited on the electrode plate surface cannot be removed in time, significantly reducing the wastewater treatment efficiency.

[0005] Therefore, we propose a multi-stage electrocatalytic oxidation degradation device to address the problems mentioned above.

[0006] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a multi-stage electrocatalytic oxidation degradation device to solve the problems currently existing in the market as mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides a multi-stage electrocatalytic oxidation degradation device, comprising a degradation tank; several sets of electrode groups disposed within the degradation tank, each set including an electrode plate one and an electrode plate two; a spacing adjustment component disposed on the degradation tank and pulsatorically connected to the electrode plate one and the electrode plate two; a mounting plate and a linear drive component mounted on the top of the degradation tank, the linear drive component being pulsatorically connected to the mounting plate; and a scraper movably mounted on the surfaces of the electrode plate one and the electrode plate two, the scraper also being slidably connected to the mounting plate.

[0009] Preferably, the number of the spacing adjustment components is the same as the number of the electrode groups, and each group includes: two connecting plates, which are fixed to electrode plate one and electrode plate two respectively; a first rack and a second rack, which are fixed perpendicularly to the two connecting plates respectively, and the two adjacent sides of the first rack have meshing teeth, and the first rack and the second rack are connected to a first gear on the degradation tank to form a transmission connection; a second gear, which is fixedly mounted with a rotating shaft, the rotating shaft being rotatably connected to the degradation tank, and the second gear meshing with the first rack; and a handwheel is fixedly mounted on one end of the rotating shaft.

[0010] Preferably, the mounting plate includes: a movable plate with a U-shaped structure, which is slidably mounted on the upper end of the degradation tank with its recess facing downward; a guide rod, which is fixedly mounted in the recess of the movable plate, and the scraper is also slidably mounted on the guide rod.

[0011] Preferably, the linear drive assembly includes: a motor, fixedly mounted on the degradation tank; a lead screw, rotatably connected to the degradation tank and fixed to the output shaft of the motor; and a movable plate threadedly sleeved on the lead screw.

[0012] Preferably, the connecting plate has a groove, the scraper has an "H" shaped structure, and its middle part passes through the groove of the connecting plate, while its two ends are respectively attached to the two surfaces of the first electrode plate and the two surfaces of the second electrode plate.

[0013] Preferably, the device further includes a limiting component, which comprises: a limiting gear with triangular teeth, the limiting gear being fixedly mounted on a rotating shaft; a connecting rod with a trapezoidal locking block fixedly mounted at its end, the trapezoidal locking block engaging with the teeth of the limiting gear; a spring sleeved on the connecting rod; and a connecting block fixed on the degradation tank, the connecting rod being movably mounted on the connecting block, and both ends of the spring being fixed to the trapezoidal locking block and the connecting block, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The present invention uses a spacing adjustment component installed on the degradation tank to manually adjust the spacing between electrode plate one and electrode plate two. At the same time, the linear drive component controls the movement of the mounting plate to drive the scraper to move along the surface of electrode plate one and electrode plate two to scrape off the residue on the surface of the electrode plates. Since the scraper is attached to the surface of electrode plate one and electrode plate two and is also slidably connected to the mounting plate, any adjustment of the spacing will not affect the normal operation of the scraper, thereby achieving the effect of convenient cleaning of electrode plate one and electrode plate two.

[0016] (2) This utility model uses a limiting component installed on the degradation tank to limit the displacement of electrode plate one and electrode plate two, preventing the distance between electrode plate one and electrode plate two from changing due to the push of water in the degradation tank. At the same time, it is simple to operate and easy to use.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0030] Please see Figures 1-6 A multi-stage electrocatalytic oxidation degradation device includes: a degradation tank 1; several sets of electrode groups disposed in the degradation tank 1, each set including an electrode plate 2 and an electrode plate 3; a spacing adjustment component 4 disposed on the degradation tank 1 and drivenly connected to the electrode plate 2 and the electrode plate 3; a mounting plate 5 and a linear drive component 6 mounted on the top of the degradation tank 1, the linear drive component 6 being drivenly connected to the mounting plate 5; and a scraper 7 movably mounted on the surface of the electrode plate 2 and the electrode plate 3, and the scraper 7 is also slidably connected to the mounting plate 5.

[0031] In the above technical solution, the spacing adjustment component 4 is used to manually adjust the spacing between electrode plate 2 and electrode plate 3. Simultaneously, the linear drive component 6 controls the movement of the mounting plate 5 to drive the scraper 7 to move along the surfaces of electrode plate 2 and electrode plate 3 to scrape away residue. Because the scraper 7 is attached to the surfaces of electrode plate 2 and electrode plate 3, and is also slidably connected to the mounting plate 5, any adjustment of the spacing will not affect the normal operation of the scraper. Specifically, with... Figure 1 For reference, when the distance between electrode plate 2 and electrode plate 3 increases, the scraper 7 mounted on their surfaces is driven to move together, and the direction of movement is always along the direction of mounting plate 5. During the movement, the scraper 7 and mounting plate 5 only have relative displacement, rather than being separated from mounting plate 5. Therefore, when mounting plate 5 moves, it can still drive the scraper 7 to slide, so as to remove the deposits on electrode plate 2 and electrode plate 3.

[0032] The number of spacing adjustment components 4 is the same as the number of electrode groups, and each group includes: two connecting plates 41, which are fixed to electrode plate 2 and electrode plate 3 respectively; a first rack 42 and a second rack 43, which are fixed perpendicularly to the two connecting plates 41 respectively, and the two adjacent sides of the first rack 42 have meshing teeth. The first rack 42 and the second rack 43 are connected to the first gear 44 rotatably connected to the degradation tank 1 to form a transmission connection; a second gear 45, which is fixedly mounted with a rotating shaft 46, which is rotatably connected to the degradation tank 1, and the second gear 45 meshes with the first rack 42; and a handwheel 47 is fixedly mounted on one end of the rotating shaft 46.

[0033] The operator holds the handwheel 47 and rotates it, which in turn drives the rotating shaft 46 to rotate. This causes the second gear 45 to drive the first rack 42 to move linearly. The first rack 42 drives the second rack 43 to move linearly through the first gear 44, and the second rack 43 always moves in the opposite direction to the first rack 42.

[0034] The mounting plate 5 includes: a movable plate 51, which has a U-shaped structure and is slidably mounted on the upper end of the degradation tank 1 with its recess facing downward; a guide rod 52, which is fixedly mounted in the recess of the movable plate 51; and a scraper 7, which is also slidably mounted on the guide rod 52.

[0035] The linear drive assembly 6 includes: a motor 61, which is fixedly mounted on the degradation tank 1; a lead screw 62, which is rotatably connected to the degradation tank 1 and fixed to the output shaft of the motor 61; and a movable plate 51 threadedly sleeved on the lead screw 62.

[0036] The connecting plate 41 has a groove, and the scraper 7 has an "H" shaped structure, with its middle part passing through the groove of the connecting plate 41, and its two ends respectively attached to the two surfaces of the electrode plate 1 2 and the two surfaces of the electrode plate 2 3.

[0037] It also includes a limiting component 8, which includes: a limiting gear 81 with triangular teeth, the limiting gear 81 being fixedly mounted on the rotating shaft 46; a connecting rod 82 with a trapezoidal locking block 83 fixedly mounted at its end, the trapezoidal locking block 83 being engaged in the teeth of the limiting gear 81; a spring 84 being sleeved on the connecting rod 82; and a connecting block 85 being fixed on the degradation tank 1, the connecting rod 82 being movably mounted on the connecting block 85, and the two ends of the spring 84 being fixed to the trapezoidal locking block 83 and the connecting block 85, respectively.

[0038] When in use, when the handwheel 47 is turned in one direction, the trapezoidal block 83 is squeezed out from the meshing teeth of the limiting gear 81, so that the spacing adjustment component 4 can be used normally. After the rotation stops, under the action of the spring 84, the trapezoidal block 83 is pressed into the meshing teeth of the limiting gear 81, thereby completing the limiting.

[0039] Working principle: During use, wastewater is input and output through the inlet and outlet at both ends of the degradation tank 1. Electrode plates 2 and 3 operate. When the distance between electrode plates 2 and 3 needs to be adjusted, it is done through the distance adjustment component 4. When electrode plates 2 and 3 need to be cleaned, the linear drive component 6 is controlled to drive the mounting plate 5 to scrape back and forth on the surfaces of electrode plates 2 and 3, and then rinsed.
