They are widely used in the deep treatment of industrial wastewater and municipal sewage, as well as in the process of reclaimed water reuse.

[0003] In the prior art, CN217323514U discloses a novel ozone dosing device for wastewater treatment in the dyeing and printing industry. It is equipped with a rotating aeration stone to spray ozone. However, it cannot spray oxygen on all the wastewater, which can easily lead to local high concentrations and incomplete reactions, resulting in low ozone utilization and increased treatment costs. Therefore, we disclose an ozone dosing device for treating chemical wastewater to meet people's needs. Utility Model Content

[0018] 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.

[0019] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows: An ozone dosing device for treating chemical wastewater includes a work cabinet 1. A wastewater tank 7 and an ozone generator 4 are fixedly installed on the bottom inner wall of the work cabinet 1. The ozone generator 4 is prior art and can be referred to in the background art. It will not be described in detail here. An oxygen inlet pipe 3 is fixedly installed at the air inlet end of the ozone generator 4, and an outlet pipe 5 is fixedly installed at the air outlet end of the ozone generator 4. A central pipe 13 is rotatably installed at the center of the bottom inner wall of the wastewater tank 7. The top end of the central pipe 13 passes through the top of the wastewater tank 7 and is rotatably connected to the outlet pipe 5. A drive mechanism for rotating the central tube 13 is installed on one inner wall of the work cabinet 1. A fan-shaped baffle 12 is fixedly installed on the three inner walls of the wastewater tank 7. The side of the fan-shaped baffle 12 away from the ozone generator 4 contacts the side of the central tube 13. A water-passing plate 17 is fixedly installed on the central tube 13. The three sides of the water-passing plate 17 away from the central tube 13 contact the top side, bottom side and annular inner wall of the wastewater tank 7, respectively. A plurality of evenly arranged water-passing holes 18 are opened on the side of the water-passing plate 17. An air-exhausting mechanism is fixedly installed on the side of the central tube 13. The plurality of air-exhausting mechanisms are located in the plurality of water-passing holes 18.

[0020] With the above structure: during use, wastewater is discharged through the inlet pipe 8, and then oxygen is discharged into the ozone generator 4 through the oxygen inlet pipe 3. The ozone generator 4 converts the oxygen into ozone, and then the drive mechanism causes the central pipe 13 and the water-passing plate 17 to rotate, so that the wastewater in the wastewater tank 7 needs to pass through the water-passing hole 18. With the help of the gas outlet mechanism, ozone can be sprayed onto all the wastewater, so that the ozone reacts fully with the wastewater.

[0021] like Figure 4 As shown, the gas outlet mechanism includes an oxygen outlet cylinder 19, which is connected to the interior of the central tube 13. Multiple evenly spaced nozzles 20 are fixedly installed at the top and bottom of the oxygen outlet cylinder 19, and these nozzles are connected to the interior of the cylinder. Wastewater in the wastewater tank 7 must pass through the water passage 18, allowing the multiple nozzles 20 to spray ozone onto all the wastewater, ensuring a complete reaction between the ozone and the wastewater.

[0022] like Figure 4 As shown, the gas outlet mechanism also includes a slide cylinder 21 slidably mounted on the inner wall of the oxygen outlet cylinder 19. A spring 22 is fixedly mounted on the end of the slide cylinder 21 away from the central tube 13. The end of the spring 22 away from the central tube 13 is fixedly mounted on the inner wall of the oxygen outlet cylinder 19. Multiple connecting holes 23 are provided on both the bottom and top inner walls of the slide cylinder 21. The connecting holes 23 and the nozzle 20 are located on the same straight line but are staggered in position. When the output pipe 5 no longer discharges gas into the central tube 13, the connecting holes 23 are staggered from the nozzle 20 under the action of the spring 22, thereby preventing wastewater from entering the oxygen outlet cylinder 19 and the central tube 13 through the nozzle 20.

[0023] like Figure 4 As shown, a gap is left between the side of the slide cylinder 21 away from the central pipe 13 and the inner wall of the oxygen outlet cylinder 19 away from the central pipe 13, with the oxygen outlet cylinder 19 located in the middle of the water passage hole 18. The advantage of this arrangement is that it allows the slide cylinder 21 to move.

[0024] like Figure 2 and Figure 3As shown, the drive mechanism includes an electric telescopic rod 6 fixedly installed on the inner wall of the work cabinet 1. A rack 16 is fixedly installed on the movable end of the electric telescopic rod 6, and a gear 14 is fixedly sleeved on the central tube 13. The gear 14 meshes with the rack 16. By activating the electric telescopic rod 6, the movable end of the electric telescopic rod 6 is stretched, which drives the rack 16 to move. The movement of the rack 16 drives the gear 14 to rotate, and the rotation of the gear 14 drives the central tube 13 to rotate.

[0025] like Figure 3 As shown, a sealing ring 15 is fixedly installed on the top of the gear 14 at the connection between the output pipe 5 and the central pipe 13. The sealing ring 15 can seal the connection between the output pipe 5 and the central pipe 13.

[0026] like Figure 2 As shown, an inlet pipe 8 and an outlet pipe 9 are fixedly installed on the side of the wastewater tank 7. The ends of the inlet pipe 8 and the outlet pipe 9, away from the wastewater tank 7, extend to the outside of the work cabinet 1. The inlet pipe 8 and the outlet pipe 9 facilitate the inflow and outflow of wastewater from the wastewater tank 7, and a valve is installed in the outlet pipe 9.

[0027] like Figure 1 and Figure 3 As shown, a groove 10 is provided on one side of the fan-shaped baffle 12, and an ozone concentration sensor 11 is installed in the groove 10. A controller 2 is installed on the side of the work cabinet 1. The ozone concentration sensor 11 can detect the ozone concentration of the wastewater. When the concentration reaches the standard, a signal is sent to the controller 2, which controls the ozone generator 4 and the electric telescopic rod 6 to stop working. The side of the fan-shaped baffle 12 corresponds to the water flow plate 17. The advantage of this arrangement is that the fan-shaped baffle 12 can contact the side of the water flow plate 17, thereby achieving complete discharge of wastewater.

[0028] Working principle: In use, wastewater is discharged through the inlet pipe 8, and then oxygen is discharged into the ozone generator 4 through the oxygen inlet pipe 3. The ozone generator 4 converts the oxygen into ozone, which then enters the slide cylinder 21 through the outlet pipe 5 and the central pipe 13. The pressure inside the slide cylinder 21 increases, causing the slide cylinder 21 to slide along the oxygen outlet cylinder 19. The spring 22 deforms, and at the same time, the connecting hole 23 aligns with the nozzle 20, allowing oxygen to be discharged through the nozzle 20. Simultaneously, the electric telescopic rod 6 is activated. The movable end of the electric telescopic rod 6 is stretched, which drives the rack 16 to move. The movement of the rack 16 drives the gear 14 to rotate. The rotation of the gear 14 drives the central tube 13 to rotate. The rotation of the central tube 13 drives the water-passing plate 17 to rotate. After the water-passing plate 17 contacts the side of the fan-shaped baffle plate 12, the movable end of the electric telescopic rod 6 moves in the opposite direction, so that the wastewater in the wastewater tank 7 needs to pass through the water-passing hole 18, so that multiple nozzles 20 can spray ozone onto all the wastewater, allowing the ozone to fully react with the wastewater. The ozone concentration sensor 11 can detect the ozone concentration in the wastewater. When the concentration reaches the standard, it sends a signal to the controller 2. The controller 2 controls the ozone generator 4 and the electric telescopic rod 6 to stop working. The output pipe 5 no longer discharges gas into the central pipe 13. Under the action of the spring 22, the connecting hole 23 is misaligned with the nozzle 20, thereby preventing wastewater from entering the oxygen outlet cylinder 19 and the central pipe 13 through the nozzle 20.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
