The impurities will also flow into the corresponding collection tank under the filtration of the filter plate. When the filter plate rotates, the collection tank can move upward to the specified position and unload the impurities inside;

[0016] S2. When the aqueous solution reaches the mixing barrel, the dosing device can add the oxidant into the aqueous solution. When the driving frame rotates, the ultraviolet lamp rod and the stirring shaft can move synchronously in a circle. When the ultraviolet lamp rod moves in a circle, the irradiation position can be continuously changed to increase the irradiation area. When the stirring shaft moves in a circle, it can fully stir the water and the oxidant to fully react.

[0017] The present invention has a novel and ingenious structure and has the following advantages compared with the prior art:

[0018] When in use, through the drive frame, ultraviolet lamp rod, stirring shaft and dosing device, the dosing device can add oxidant to the inner wall of the mixing barrel, the ultraviolet lamp rod can disinfect the water in the mixing barrel and kill pathogenic microorganisms in the water, and can stimulate oxygen or hydrogen peroxide in the water under the irradiation of ultraviolet rays, so that it decomposes and generates highly active free radicals. Free radicals are very strong oxidants and can quickly react with pollutants, thereby accelerating the oxidation reaction. The stirring shaft can continuously stir the water inside the mixing barrel when working, thereby accelerating the reaction; when the drive frame rotates, the ultraviolet lamp rod, stirring shaft, dosing device, etc. can be synchronized and rotated. The ultraviolet lamp can continuously change the irradiation position when it moves in a circle, and fully irradiate the water body to prevent dead angles. The stirring shaft can continuously change the stirring position when it moves in a circle, and fully and evenly stir the water body to accelerate the reaction. The dosing device can continuously change the dosing position when it moves in a circle, so that the medicine is more fully distributed evenly. The water source enters the filter box from the water inlet, and flows into the mixing barrel under the action of gravity. The filter box can filter the particulate impurities in the water. When the water in the filter box flows into the mixing barrel, the impurities in the water can be blocked and filtered through the filter plate set. The plate is in an inclined state under normal conditions. Impurities can move downward into the collection tank at the bottom under the impact of gravity and water flow. The collection tank is hollow. The upper and lower ports are opened to facilitate the reception and unloading of impurities. When the filter cover is flipped upward to the top, the lower port can be sealed to receive impurities. When the filter cover is flipped downward, the lower port can be opened to unload impurities. The upper port is always open to receive filtered impurities. When the impurities in the collection tank are full, the filter plate can be driven to rotate to flip to the inclined state toward the other end, that is, the filter plate can be tilted and flipped from the lower right to the lower left. Tilt, that is, the collecting trough at the left end will swing downward, and the collecting trough at the right end will swing upward. When the collecting trough at the left end swings downward, the filter cover can be flipped upward to close the lower port of the collecting trough. When the filter plate continues to filter the sewage, the impurities on the upper end of the filter plate will flow into the collecting trough at the left end under the action of gravity. When the collecting trough at the right end swings upward, the filter cover can be flipped downward to open the lower port of the collecting trough. At this time, the impurities in the collecting trough at the right end will fall to the designated position under the action of gravity, thus completing the cleaning of the impurities. The filter box can efficiently filter water and clean impurities without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-Figure 10 , Fig.14As shown, a plurality of supporting legs 2 are fixedly connected to the inner wall of the outer periphery of the base 1, and the base 1 and the supporting legs 2 are used to support the entire device. The mixing barrel 3 is fixedly connected to the base 1, and the mixing barrel 3 is used to receive and process filtered water. A thread is provided on the outer surface of the bottom end cover 51, which is threadedly connected to the mixing barrel 3, so that the bottom end cover 51 can be disassembled. After the bottom end cover 51 is disassembled, it is convenient to regularly clean the pollutants adhering to the inner wall of the mixing barrel 3. It is very inconvenient to clean the inner wall of the traditional tubular treatment device. The mixing barrel 3 and the bottom end cover 51 can replace the tubular treatment device, and can be disassembled for regular cleaning of the inner wall; the driving frame 52, the ultraviolet lamp rod 54, the stirring shaft 57 and the dosing device are provided, and the dosing device can add an oxidant to the inner wall of the mixing barrel 3, and the ultraviolet lamp rod 54 can disinfect the water in the mixing barrel 3 to kill pathogenic microorganisms in the water, and Moreover, under the irradiation of ultraviolet rays, oxygen or hydrogen peroxide in the water can be stimulated to decompose and generate highly active free radicals. Free radicals are very strong oxidants and can react quickly with pollutants, thereby accelerating the oxidation reaction. The ultraviolet lamp rod 54, the oxidant, etc. are all prior art and will not be described in detail. The stirring shaft 57 can continuously stir the water inside the mixing barrel 3 during operation, thereby accelerating the reaction; when the driving frame 52 rotates, the ultraviolet lamp rod 54, the stirring shaft 57, the dosing device, etc. can be synchronously moved in a circular motion.

The stirring shaft 57 can continuously change the stirring position during the circular motion, and fully and evenly stir the water body to accelerate the reaction. The dosing device can continuously change the dosing position during the circular motion, so that the drug is more fully and evenly distributed.A water inlet 5 is provided at the upper end of the filter box 4, and the lower end of the filter box 4 is connected to the mixing barrel 3 pipe. Water enters the filter box 4 through the water inlet 5, and can flow into the mixing barrel 3 under the action of gravity. The filter box 4 can filter particulate impurities in the water. When the water in the filter box 4 flows into the mixing barrel 3, the impurities in the water can be blocked and filtered through the filter plate 27. The filter plate 27 is in an inclined state under normal conditions. Impurities can move downward under the impact of gravity and water flow and enter the collecting tank 37 at the bottom. The collecting tank 37 is hollow. The upper and lower ports are opened to facilitate the reception and unloading of impurities. When the filter cover 46 is flipped upward to the top, the lower port can be sealed to receive impurities. When the filter cover 46 is flipped downward, the lower port can be opened to unload impurities. The upper port is always open to receive filtered impurities. When the impurities in the collecting tank 37 When the impurities are full, the filter plate 27 can be driven to rotate so that the filter plate 27 can be flipped to the tilted state toward the other end, that is, the filter plate 27 can be tilted from the lower right to the lower left, that is, the collection slot 37 at the left end will swing downward, and the collection slot 37 at the right end will swing upward. When the collection slot 37 at the left end swings downward, the filter cover 46 can be flipped upward to close the lower end of the collection slot 37. When the filter plate 27 continues to filter the sewage, the impurities on the upper end of the filter plate 27 will flow into the collection slot 37 at the left end under the action of gravity. When the collection slot 37 at the right end swings upward, the filter cover 46 can be flipped downward to open the lower end of the collection slot 37. At this time, the impurities in the collection slot 37 at the right end will fall into the designated position under the action of gravity, that is, the cleaning work of the impurities is completed. The filter box 4 can filter the water efficiently and clean the impurities without stopping the machine. ;

[0039] The front and rear end surfaces of the filter box 4 are respectively provided with a rotatable first spur gear 26, the filter plate 27 is coaxially fixed to the inner ends of the two first spur gears 26, the front and rear sides of the inner walls of the upper and lower ends of the filter plate 27 are respectively fixed with connecting shafts 39, the collecting grooves 37 are respectively rotatably connected to the outer surfaces of the corresponding two connecting shafts 39, the front and rear end inner walls of the filter box 4 are also respectively hinged with long connecting rods 34 parallel to the filter plates 27, the front and rear sides of the upper end surface of the collecting groove 37 are respectively fixed with extension seats 38, and the extension seats 38 are respectively hinged to the upper and lower ends of the corresponding long connecting rods 34.

[0040] like Figure 8-Figure 9As shown, the collection tank 37 is rotatably connected to the collection tank 37 through the connection shaft 39, which is equivalent to the collection tank 37 being hinged at the upper and lower ends of the filter plate 27; the inner wall at the center of the first spur gear 26 is respectively fixed with a rotating shaft, which passes through the inner walls of the front and rear ends of the filter box 4 and is rotatably connected to the filter box 4, and the inner end faces of the two rotating shafts are respectively fixed to the filter plate 27. When the first spur gear 26 rotates, it can drive the filter plate 27 to rotate; the middle part of the long connecting rod 34 is fixed with a hinge shaft, which is rotatably connected to the inner end face of the filter box 4, When the long connecting rod 34 is hinged on the inner wall of the filter box 4, the distance from the connecting shaft 39 to the hinge of the extension seat 38 and the long connecting rod 34 is equal to the distance from the rotating shaft to the hinge axis. Through the hinge of the set extension seat 38 and the long connecting rod 34, the filter plate 27, the long connecting rod 34, and the collecting groove 37 can indirectly form a parallelogram mechanism, that is, when the filter plate 27 rotates, it can drive the corresponding collecting groove 37 to flip and swing up and down, and the upper port of the collecting groove 37 is always vertically upward to prevent impurities inside the collecting groove 37 from falling.

[0041] The filter cover 46 is hinged on the lower end surface of the collecting groove 37, and the front and rear end surfaces of the collecting groove 37 are respectively slidably connected with movable square sliders 44. The outer end surfaces of the two square sliders 44 are respectively fixed with first sliding pins 43, and the outer surfaces of the first sliding pins 43 are respectively rotatably connected with short connecting rods 45, and the lower ends of the short connecting rods 45 are respectively hinged on the corresponding front and rear end surfaces of the filter cover 46.

[0042] like Figure 9-10 As shown, the filter cover 46 is provided with a through hole, which can filter the water in the impurities, and the square slider 44 can be slidably connected to the inner wall of the collection tank 37, and the square slider 44 can move left and right; the installation and shape of the first sliding pin 43, the short connecting rod 45, and the filter cover 46 are as shown Fig.10 As shown, when the left and right square sliders 44 move inward, they can drive the first sliding pin 43 and the upper end of the short connecting rod 45 to move inward, and the lower end of the short connecting rod 45 will drive the filter cover 46 to flip downward. When the filter cover 46 flips downward, the collecting tank 37 can be opened. At this time, the impurities in the collecting tank 37 can be unloaded to the designated position. Similarly, when the two square sliders 44 move outward, they can drive the filter cover 46 to flip upward. When the filter cover 46 flips upward, the bottom of the collecting tank 37 can be sealed, and the collecting tank 37 can receive the loaded impurities.

[0043] The outer surfaces of the connecting shafts 39 are fixedly connected with sector plates 40 , and the sector plates 40 are respectively provided with arc grooves 41 and diameter-changing grooves 42 that match the first sliding pins 43 .

[0044] like Fig. 9As shown, the sector plate 40 is equivalent to being fixed on the filter plate 27, the arc groove 41 is a groove of equal radius opened with the connecting shaft 39 as the center, and the variable diameter groove 42 is arranged to gradually approach the connecting shaft 39 downward. When the collecting groove 37 is turned downward with the connecting shaft 39 as the center, the first sliding pin 43 can slide in the circumference of the inner wall of the arc groove 41, and the first sliding pin 43 will not move to the left or right on the collecting groove 37, that is, the first sliding pin 43 and the square slider 44 can remain relatively still with the collecting groove 37, that is, they can move in a synchronous circumferential manner with the collecting groove 37, that is, the corresponding filter cover 46 will not be turned over and opened, and when the first sliding pin 43 When the filter plate 27 rotates, the collecting groove 37 can be driven to swing up and down. When the collecting groove 37 swings up and down, it can always maintain a horizontal state under the limit of the long connecting rod 34, and will interact with the filter plate 27 and the fan-shaped plate 40. The collecting groove 37 can rotate and move on the connecting shaft 39 when it swings up and down. When the collecting groove 37 rotates and moves, it can also drive the square slider 44, the first sliding pin 43, and the short connecting rod 45 to rotate and move. When the first sliding pin 43 rotates and moves, it will not move left and right under the meshing with the arc groove 41. When the first sliding pin 43 rotates and moves to enter the inner wall of the reducing groove 42, the first sliding pin 43 continues to rotate and move inward, that is, it moves inward near the center of the connecting shaft 39. When the first sliding pin 43 moves inward, it can drive the short connecting rod 45 to move downward and the filter cover 46 to flip downward. That is, by the mutual cooperation of the first sliding pin 43, the arc groove 41 and the reducing groove 42, when the collecting groove 37 swings upward, that is, the first sliding pin 43 is on the inner wall of the arc groove 41, the filter cover 46 will not flip downward, that is, it will be in a closed state. When the collecting box continues to swing upward to the specified position, the first sliding pin 43 can enter the inner wall of the reducing groove 42, and the filter cover 46 begins to flip downward and open, so that the impurities in the collecting groove 37 are poured into the specified position; similarly, when the collecting groove 37 flips downward, the filter cover 46 can flip upward to close the lower port of the collecting groove 37. The principle is the same and will not be repeated.

[0045] The lower ends of the long connecting rods 34 are fixedly connected to pull seats 35, and the inner walls of the pulling seats 35 are fixedly connected to tension springs 36. A scraper 31 is slidably connected to the inner end faces of the two long connecting rods 34, and the upper ends of the tension springs 36 are fixedly connected to the scraper 31. The inner walls of the scraper 31 are slidably connected to scrapers 33 that match the filter plate 27, and the front and rear sides of the inner walls of the bottom ends of the scraper 31 are respectively fixedly connected to first springs 32 that match the scraper 33. A pulley 29 is rotatably connected to the inner sides of the two long connecting rods 34, and a pull rope 28 is sleeved on the outer surface of the pulley 29. One end of the pull rope 28 is fixedly connected to the scraper 31, and the other end of the pull rope 28 is fixedly connected to the inner wall of the filter box 4.

[0055] A method for using a device for removing pollutants by catalytic oxidation comprises the following steps:

[0056] S1. Add water into the filter box 4. Impurities in the water can be filtered under the filtration of the filter plate 27. The filtered aqueous solution will flow into the mixing barrel 3. Impurities will also flow into the corresponding collection tank 37 under the filtration of the filter plate 27.

The filter box 4 can filter the particulate impurities in the water. When the water in the filter box 4 flows into the mixing barrel 3, the impurities in the water can be blocked and filtered by the filter plate 27 set. The filter plate 27 is always The impurities can move downward into the collecting tank 37 at the bottom under the impact of gravity and water flow.

When the filter cover 46 is flipped downward, the lower port can be opened to unload impurities, and the upper port is always open to receive filtered impurities. When the impurities in the collecting tank 37 are full, the filter plate 27 can be driven to rotate to flip the filter plate 27 to the tilted state toward the other end, that is, the filter plate 27 can be tilted from the lower right to the lower left, that is, the left end The collecting trough 37 at the right end will swing downward, and the collecting trough 37 at the left end will swing upward. When the collecting trough 37 at the left end swings downward, the filter cover 46 can be flipped upward to close the lower port of the collecting trough 37. When the filter plate 27 continues to filter the sewage, the impurities on the upper end of the filter plate 27 will flow into the collecting trough 37 at the left end under the action of gravity. When the collecting trough 37 at the right end swings upward, the filter cover 46 can be flipped downward to open the lower port of the collecting trough 37. At this time, the impurities in the collecting trough 37 at the right end will fall to the designated position under the action of gravity, thus completing the cleaning of the impurities. The filter box 4 can efficiently filter the water and clean the impurities without stopping the machine.
