[0028] Example 1

[0029] A catalytic oxidation water treatment device, such as Figure 1-5 As shown, it includes a lower chamber 1, with an upper chamber 2 disposed at the upper end of the lower chamber 1. The upper chamber 2 and the lower chamber 1 are connected by a connecting mechanism 3, which can control the separation or combination of the upper chamber 2 and the lower chamber 1. A filter assembly 4 is disposed between the lower chamber 1 and the upper chamber 2. The sidewalls of the upper chamber 2 and the lower chamber 1 are respectively connected to a water outlet 5 and a water inlet 6. The lower chamber 1 is provided with an aeration and stirring structure 7, which is connected to an ozone generator 8. The top of the upper chamber 2 is connected to a gas recovery line 9, which is connected to the air inlet of the ozone generator 8. The upper chamber 2 is provided with an ultraviolet light source, which can be used to treat water by irradiating the generated ultraviolet light.

[0030] The lower end of the upper bin 2 is open, and the upper end of the lower bin 1 is open. Sealing rings 12 are provided at the opposite end surfaces of the upper bin 2 and the lower bin 1. When the upper bin cover is closed on the lower bin, the sealing ring can play a sealing role.

[0031] The filter assembly 4 includes an outer support ring 13, on which a filter screen 14 is mounted. Correspondingly, bent protrusions 11 are provided on the lower sidewalls of the upper chamber 2 and the upper sidewalls of the lower chamber 1. A sealing ring is provided between the bent protrusions and the outer support ring, thereby forming a seal between the bent protrusions and the outer support ring, ensuring that water flowing from the lower chamber to the upper chamber is filtered by the filter screen.

[0032] In addition, at least two layers of filters 14 are positioned parallel to the outer support ring 13. The mesh size of the filters 14 increases from bottom to top, allowing the lower, larger-pore filter to intercept bulky contaminants such as flocculants, before the smaller-pore filter performs deep filtration. The filters can be conventional activated carbon filters, and the outer support ring is constructed of a soft material such as rubber, allowing for slight deformation during removal and replacement, facilitating easy insertion and removal.

[0033] The connection mechanism 3 includes several pairs of lower and upper lugs 15 and 16, respectively fixedly mounted on the lower and upper compartments 1 and 2. These lower and upper lugs 15 and 16 are circumferentially fixed. The lower lugs 15 are provided with threaded holes, connected to studs 17. Studs 17 have columns 18 at their upper ends, which are equipped with disc-shaped baffles 19. Upper lugs 16 have U-shaped seats 20 for limiting the axial position of disc-shaped baffles 19. A rotary handle 21 is located at the upper end of columns 18. In this embodiment, three pairs of upper and lower lugs are provided, circumferentially and evenly spaced on the outer walls of the upper and lower compartments.

[0034] Correspondingly, an air pipe 22 is provided at the top of the upper bin 2, and a valve is provided on the air pipe 22. Before and after the upper bin and the lower bin are separated, the valve is opened to maintain the internal and external air pressure balance.

[0035] When the filter assembly needs to be replaced, the three handles 21 are rotated simultaneously, driving the lower stud 17 to rotate. As a result, under the threaded cooperation between the stud 17 and the lower ear seat 15, and the limiting effect of the U-shaped seat 20 on the disc-shaped baffle 19, the upper chamber 2 where the upper ear seat 16 is located is pushed upward away from the lower chamber 1, thereby separating the upper and lower chambers, thereby facilitating the removal of the filter assembly 4 located between the upper and lower chambers from the opening for replacement or cleaning. Specifically, when the handles 21 are rotated, the stud 17 moves upward, and the disc-shaped baffle 19 on the column 18 rises synchronously, abuts against the upper ear seat 16, and pushes the upper chamber 2 where the upper ear seat 16 is located upward away from the lower chamber 1. When the upper chamber 2 and the lower chamber 1 need to be closed, the three handles 21 are rotated in the opposite direction. When the handles 21 are rotated, the stud 17 moves downward, and the disc-shaped baffle 19 on the column 18 descends synchronously, abuts against the U-shaped seat 20, and pushes the upper chamber 2 where the upper ear seat 16 is located downward toward the lower chamber 1.

[0036] The aeration and stirring structure 7 includes a central tube 23 that is rotatably arranged at the bottom of the lower bin 1. The lower end of the central tube 23 passes through the lower bin 1 and is connected to the ozone generator 8 through a rotary joint 24. The lower end of the central tube 23 is connected to a driver 26 fixedly arranged at the bottom of the lower bin 1 through a belt transmission pair 25. The central tube 23 passes into the lower bin 1 and is fixedly connected to a stirring tube 27 at its upper end. The stirring tube 27 is provided with a plurality of air holes. The belt transmission pair mainly consists of a driving pulley, a driven pulley and a transmission belt. The driving pulley is usually connected to the power source (i.e., the technical solution is connected to the driver) and drives the transmission belt to move by rotation. The driven pulley receives the power transmitted by the transmission belt and then drives the working parts connected to it (the driven pulley is fixedly connected to the central tube). The transmission belt can be of different types such as flat belt, V-belt, synchronous belt, etc., and is selected according to the specific transmission requirements.

[0037] When in use, the driver is turned on, and the driver drives the central tube 23 to rotate under the action of the belt transmission pair, and the central tube 23 synchronously drives the stirring tube 27 to rotate, thereby achieving a stirring effect. At the same time, the ozone generator supplies air to the central tube 23, and the air is discharged into the lower bin 2 through the air holes on the stirring tube 27, thereby realizing the ozone oxidation function.

[0038] As an optional solution, in actual use, an ultraviolet catalyst can be set in the upper chamber and an ozone catalyst can be set in the lower chamber to improve the catalytic oxidation efficiency and increase the water treatment speed.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
