[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a micro-nano ozone catalytic oxidation device, including a processing barrel 1, the processing barrel 1 is in the shape of a cylinder, and a support leg is provided at the bottom of the processing barrel 1. A rotating mechanism 2 is provided inside the processing barrel 1, and the rotating mechanism 2 includes a motor 21. The height of the motor 21 is less than the height of the support leg at the bottom of the processing barrel 1.

The upper outer wall of the processing barrel 1 is provided with a protrusion whose shape matches the shape of the groove provided on the inner wall of the barrel cover 24, and the number of protrusions and grooves is consistent with the number of sides of the cross-sectional shape of the connecting groove 23. The upper outer wall of the barrel cover 24 is clamped with the inner wall of the barrel cover 24. The top of the barrel cover 24 is fixedly connected to the feed pipe 3, the top of the barrel cover 24 is provided with an exhaust hole 4, and the bottom end of the processing barrel 1 is fixedly connected to the drain pipe 5.

[0035] Reference Figure 2 - Figure 4The bottom end of the barrel cover 24 is rotatably connected to a rotating shaft 25, and a slide groove 26 is provided on the outer wall of the rotating shaft 25. The cross-sectional shape of the slide groove 26 is a shape formed by connecting a rectangle and an isosceles trapezoid, and the length of the end of the isosceles trapezoid close to the center point of the rotating shaft 25 is longer than the length of the end away from the center point of the rotating shaft 25. A mounting block 27 is slidably provided on the inner wall of the slide groove 26. The shape setting of the slide groove 26 ensures that when the mounting block 27 enters the slide groove 26, it cannot be detached from the inside of the slide groove 26 in any direction except the vertical direction. The shape of the mounting block 27 matches the shape of the slide groove 26.

[0036] Reference Figure 3 、 Figure 5 and Figure 6 A storage assembly 28 is provided at the end of the mounting block 27 away from the rotating shaft 25. The storage assembly 28 includes a storage plate 281. The storage plate 281 is in the shape of a hollow rectangular parallelepiped at one end. The outer wall of the storage plate 281 is fixedly connected to the outer wall of the mounting block 27. A plate cover 282 is clamped on the outer wall of the storage plate 281. The surface with the largest area of the storage plate 281 and the surface with the largest area of the plate cover 282 are consistent in size and shape. A groove is provided at the end of the storage plate 281 close to the plate cover 282, and a protrusion made of rubber is provided at the end of the plate cover 282 close to the storage plate 281.

[0037] Reference Figure 3 、 Figure 5 and Figure 6 The inner wall of the storage plate 281 is provided with a storage groove 1 283, the inner wall of the storage groove 1 283 is an arc surface, the inner wall of the plate cover 282 is provided with a storage groove 2 284, the storage groove 1 283 and the storage groove 2 284 have the same shape, and the storage groove 1 283 and the storage groove 2 284 are at the same horizontal position, the storage plate 281 and the plate cover 282 are at the same horizontal position as the storage groove 1 283 or the storage groove 2 284. The inner wall of the storage plate 281 is provided with a flow hole 285, the diameter of the flow hole 285 is smaller than the size of the catalyst, and the plate cover 282 is close to the storage plate 281. The end is fixedly connected with a partition 286, and the partition 286 is arranged between two storage slots 284. A discharge port 287 is provided at the end of the storage plate 281 away from the mounting block 27, and a stopper 288 is fixedly connected to the end of the plate cover 282 close to the storage plate 281. The upper outer wall of the rotating shaft 25 is fixedly connected with a control block 29. The shape of the control block 29 is a shape formed by a circular ring on the upper part and multiple protrusions on the lower part, and the distance between the protrusions on both sides of the same slide 26 where the control block 29 is arranged is consistent with the sum of the thicknesses of the storage plate 281 and the plate cover 282.

[0038] Reference Figure 2 - Figure 4A positioning block 210 slides on the lower outer wall of the rotating shaft 25, and a screw 211 penetrates and is rotatably connected to the inner wall of the positioning block 210. The outer wall of the screw 211 and the positioning block 210 are at the same vertical position and have no threads. The threads of the screw 211 are only arranged in the area where the screw 211 is above the vertical area where the positioning block 210 is located. A thread groove whose shape matches the shape of the screw 211 is opened at the bottom end of the rotating shaft 25. The outer wall of the screw 211 penetrates and is threadedly connected to the bottom end of the rotating shaft 25. The rotation direction of the motor 21 is consistent with the rotation direction of the screw 211 moving toward the direction close to the rotating shaft 25. The bottom end of the screw 211 is fixedly connected to a connecting bar 212.

[0039] Working principle: During use, when the staff needs to replace the catalyst, the staff first moves the barrel cover 24 upward and flips the barrel cover 24, so that the items originally in the area below the barrel cover 24 are moved to the upper side of the barrel cover 24, and then rotates the screw 211 to move the screw 211 away from the rotating shaft 25. When the screw 211 is rotated to be completely separated from the rotating shaft 25, the positioning block 210 is also separated from the rotating shaft 25.

[0040] When the positioning block 210 is separated from the rotating shaft 25, the staff moves the storage plate 281 and the plate cover 282 upward, so that the storage plate 281 and the plate cover 282 are separated from the rotating shaft 25. After separation, the staff moves the storage plate 281 and the plate cover 282 in the direction away from each other. Since the plate cover 282 and the storage plate 281 are only connected by the protrusion and the groove, and the protrusion part is flexible and can be deformed, the plate cover 282 and the storage plate 281 can be separated relatively easily.

[0041] When the plate cover 282 is separated from the storage plate 281, the staff first pours out the catalyst inside, and then places the new catalyst inside the storage plate 281. Then the staff takes a plate-like object whose length matches the length of the inner wall of the storage plate 281, and moves it from the end close to the mounting block 27 toward the end close to the discharge port 287. During the movement, the plate-like object is made to fit the inner wall of the storage plate 281, so that the excess catalyst can be easily discharged from the storage plate 281, and the staff can more conveniently ensure that the catalyst is evenly distributed inside the storage tank 283.

[0042] After the placement is completed, the staff will cover the plate cover 282 on top of the storage plate 281 and make the raised part enter the groove part. After the plate cover 282 and the storage plate 281 are completely fixed, the partition 286 will just separate the multiple storage slots 1 283 from the storage slots 2 284, thereby ensuring that during use, the catalysts originally in different storage slots 1 283 can be separated by the partition 286, so as to ensure that during use, the catalysts are not easily piled up together, thereby ensuring the catalytic effect.

[0043] When storage is completed, the staff will install the mounting block 27 inside the slide groove 26 again. After the installation is completed, the plate cover 282 and the storage plate 281 are just between the two protrusions of the control block 29. After that, the staff will align the screw 211 with the threaded hole, while keeping the protrusion of the positioning block 210 in a position that fits with the storage plate 281 and the plate cover 282, and rotate the screw 211, so that the screw 211 moves toward the direction close to the control block 29 during the rotation process. When the screw 211 completely enters the rotating shaft 25, the positioning block 210 is just moved to a position where the protrusion is on the outside of the storage plate 281 and the plate cover 282.

[0044] At this time, the staff closes the barrel cover 24. When closing the barrel cover 24, as the barrel cover 24 moves downward, the groove on its inner wall will gradually move to a matching position with the protrusion on the upper outer wall of the processing barrel 1. Therefore, when the barrel cover 24 is completely closed, it can ensure that the connecting strip 212 is exactly inside the connecting groove 23.

[0045] At this time, the staff will pass the sewage to be treated into the feed pipe 3, and then start the motor 21, so that the output shaft of the motor 21 drives the connecting block 22 to rotate, and when the connecting block 22 rotates, the connecting bar 212 is driven to rotate through the connecting groove 23, thereby causing the rotating shaft 25 to rotate. Since the direction of rotation of the output shaft of the motor 21 is the same as the fastening direction of the screw 211 and the rotating shaft 25, the screw 211 will not separate from the rotating shaft 25 during rotation.

[0046] During the rotation process, the rotating shaft 25 drives the storage plate 281 and the plate cover 282 to rotate, and the rotation of the storage plate 281 and the plate cover 282 drives the water inside the processing barrel 1 to rotate, so that the water can contact the catalyst in the process of entering the flow hole 285. Since both the water and the catalyst are rotating, the same surface of the catalyst is not easy to always contact the inner wall of the storage tank 1 283 or the storage tank 2 284. Moreover, the water and the catalyst are in a flowing state, so the contact time and area of the water and the catalyst can be increased, thereby reducing the catalytic time.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
