[0002] Industrial wastewater contains harmful substances such as heavy metals and organic pollutants. Direct discharge without treatment can lead to water pollution and threaten the health of ecosystems. Treated wastewater can be reused for production or ecological water replenishment, reducing pressure on natural water bodies. Ozone oxidation is necessary during the treatment of industrial wastewater to facilitate its processing.

[0003] A chemical wastewater pretreatment device for ozone oxidation, disclosed in CN222312754U, includes a shell, an air pump at the top of the shell, an exhaust pipe at the top of the air pump, a ladder on the outside of the shell, a first water inlet pipe on the outside of the shell, a motor on one side of the shell, a second water inlet pipe on one side of the shell, and a first drain pipe on the other side of the shell.

[0004] In the above document, during the stirring process, the middle section of the connecting rod will drive the rectangular plate to rotate, thereby enabling the rectangular plate to drive the sewage in the middle section of the outer shell to rotate. At this time, the rotation amplitude of the sewage in the middle section inside the outer shell is different from that of the sewage on both sides, thereby improving the fusion effect of the sewage inside the outer shell with the medicine through impact, thus improving the practicality of the device.

[0005] However, when the above-mentioned documents are used to agitate the wastewater, the wastewater contains lumpy impurities, which makes it difficult to filter and break up the oxidized wastewater. This can easily cause blockages during drainage. Therefore, we propose an industrial wastewater oxidation pretreatment device to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: an industrial wastewater oxidation pretreatment device, including a treatment tank 1, an ozone generator 4, a drive motor 8, and a crushing plate 17. An inlet 2 is located on the upper left side of the treatment tank 1, and an outlet 3 is located at the lower right end of the treatment tank 1. An ozone generator 4 is installed on top of the treatment tank 1, and its output end is connected to a gas guide pipe 5. The end of the gas guide pipe 5 is connected to a gas collecting plate 6 on the top inner side of the treatment tank 1. The gas collecting plate 6 is embedded in the upper inner side of the treatment tank 1, and jet nozzles 7 are evenly installed below the gas collecting plate 6 to facilitate the jet nozzles 7 below the gas collecting plate 6 to treat the wastewater inside the treatment tank 1. Water is used to supply ozone. A drive motor 8 is installed on the side of the treatment tank 1, and a connecting shaft 9 is fixed to the output end of the drive motor 8. Pulleys 15 are fixed to the end of the treatment tank 1 and the surface of the rotating shaft 13 through the connecting shaft 9. The pulleys 15 are connected by a transmission belt 16, which can drive the rotating shaft 13 to rotate through the connecting shaft 9 and the transmission belt 16. Fixing rods 10 are evenly fixed to the surface of the connecting shaft 9, and a shovel plate 11 is fixed to the end of the surface of the fixing rod 10. The shovel plate 11 is arc-shaped and there are five sets of shovel plates 11, which makes it easy to turn over the sewage when the arc-shaped shovel plate 11 rotates.

[0024] Please see Figure 1-5 A dirt-separating mesh frame 12 is installed on the right side of the treatment tank 1. The dirt-separating mesh frame 12 is U-shaped and is connected to the treatment tank 1 by a pull-out disassembly and installation method, which facilitates the filtration of discharged sewage through the dirt-separating mesh frame 12. A rotating shaft 13 is rotatably connected above the connecting shaft 9 on the right side of the treatment tank 1, and a cam 14 is fixed on the surface of the rotating shaft 13. A crushing plate 17 is set below the cam 14 on the right side of the treatment tank 1. Fixing blocks 18 are fixed at both ends of the right side of the treatment tank 1, and the fixing blocks 18 are connected to the crushing plate 17 by a spring 19. The crushing plate 17 is slidably connected to the upper right end of the treatment tank 1, and the upper end surface of the crushing plate 17 is fitted with the lower end surface of the cam 14, which facilitates the cam 14 to squeeze the crushing plate 17, so that the crushing plate 17 squeezes the blocky impurities in the sewage.

[0025] Working principle: First, when in use, by turning on the drive motor 8, the connecting shaft 9 drives the fixed rod 10 and the shovel plate 11 to rotate. With the use of the ozone generator 4, the air pipe 5 supplies oxygen into the gas collection plate 6, which in turn facilitates the ozone to be discharged by the jet nozzles 7 on the surface of the gas collection plate 6. As the arc-shaped shovel plate 11 drives the sewage to turn over, the sewage can come into more full contact with the ozone, thus improving the oxidation effect of the sewage.

[0026] When the connecting shaft 9 rotates, it drives the rotating shaft 13 to rotate via the transmission belt 16. This causes the rotating shaft 13 to drive the cam 14 to rotate, so that the cam 14 can squeeze the crushing plate 17. This causes the crushing plate 17 to move downwards, squeezing out the lumpy impurities in the oxidized wastewater below. At the same time, the use of the removable screen frame 12 on the device facilitates the filtration of the oxidized wastewater, improving the treatment effect of the device. The crushing plate 17 is connected to the fixed block 18 via the spring 19, which facilitates the reset of the crushing plate 17. This is the operating principle of the industrial wastewater oxidation pretreatment device.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
