[0002] In daily industrial production, various polluted solutions are produced. These pollutants have a huge impact on the environment. In serious cases, they may flow into the human body and pose a serious threat to human health. In order to make the sewage meet the water quality requirements for discharge into a certain water body or reuse, it is necessary to collect and treat the sewage; sewage collection and treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering, and is increasingly entering the daily lives of ordinary people. In the process of sewage collection and treatment, a stirring device is often used to stir the sewage.

[0003] The existing sewage stirring device only achieves mixing and stirring of sewage and dirt, and is not convenient for degrading organic pollutants in sewage during sewage stirring; therefore, it is necessary to propose an efficient stirring method and device for sewage collection. Summary of the invention

[0004] The purpose of the present invention is to provide a high-efficiency stirring method and device for sewage collection, which utilizes photocatalysts to degrade organic pollutants in sewage during stirring; in order to increase the effective area of ​​light, the law of reflection of light and the law of refraction of light are utilized to change the incident angle of light and the number of light beams formed; while stirring, sewage and dirt are gathered so that they are gathered under the light beam, further increasing the effective area of ​​light and photocatalyst, and organic pollutants in sewage can be degraded during the stirring process, thereby improving the efficiency of sewage collection and treatment and achieving the purpose of efficient sewage stirring.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an efficient stirring method and device for sewage collection, using photocatalysts to degrade organic pollutants in sewage during stirring; in order to increase the effective area of ​​light, the law of reflection and the law of refraction of light are used to change the incident angle of light and the number of light beams formed; while stirring, part of the sewage and dirt are gathered under the light beam.

[0006] The following principles and beneficial effects are achieved by adopting the above scheme:

[0007] During stirring, photocatalysts are used to degrade organic pollutants in sewage. By using a focusing tube and a hexagonal prism together, the laws of light reflection and light refraction are used to change the incident angle of light and the number of light beams formed, thereby further increasing the contact area between light and the photocatalyst. While stirring, sewage and dirt are gathered under the light beam, thereby further increasing the effective area of ​​light and the photocatalyst. Organic pollutants in sewage can be degraded during the stirring process, thereby improving the efficiency of sewage collection and treatment.

[0008] Further, the photocatalyst includes one of titanium dioxide, zinc dioxide, bismuth oxide, iron oxide and sulfide.

[0009] Beneficial effects: The photocatalytic properties of photocatalysts are utilized to absorb light energy in the ultraviolet range, excite electrons to generate electron-hole pairs, which can participate in photocatalytic reactions to generate active free radicals with oxidation or reduction capabilities, thereby promoting the degradation of organic pollutants in sewage.

[0010] Furthermore, it comprises a mixing box, the outer wall of which is fixedly connected with a driving member, the output shaft of which passes through the side wall of the mixing box and extends into the mixing box, where a mixing assembly for mixing sewage is connected;

[0011] A collection box is fixedly connected to the top of the mixing box, the upper part of the collection box is trapezoidal, and a water inlet is opened on the top of the collection box;

[0012] The side wall of the collection box is fixedly connected with a support plate, and a "7"-shaped and transparent condensing plate is fixedly connected to the top of the support plate, and the condensing plate is located above the water inlet; a plurality of condensing tubes are fixedly connected to the bottom of the condensing plate, and reflectors are fixedly connected to the curved parts of the condensing tubes; the ends of the condensing tubes away from the condensing plates all penetrate the trapezoidal inclined surface at the top of the collection box; a plurality of hexagonal prisms are fixedly connected to the inner side wall of the trapezoidal inclined surface; the end of the condensing tube connected to the trapezoidal inclined surface is opposite to the hexagonal prism located in the middle of the inner side wall of the trapezoidal inclined surface;

[0013] A water outlet is provided on the bottom wall of the mixing box; and a supporting assembly for supporting the mixing box is provided at the bottom of the mixing box.

[0014] Beneficial effects: The device is placed in sunlight, and sewage and photocatalyst are transported into the collection box and the mixing box through the water inlet; the driving part is started, and the driving part drives the rotating shaft and the stirring rod to rotate to stir the sewage and the photocatalyst; during stirring, sunlight passes through the focusing plate and the water inlet to irradiate the mixing box, and the photocatalytic properties of the photocatalyst are used to promote the degradation of organic pollutants in the sewage; the stirring action also increases the contact area between light and the photocatalyst.

[0015] Since a focusing tube is provided at the bottom of the focusing plate, when light is irradiated into the focusing tube, the light is reflected to the hexagonal prism located below it through two reflections of the reflector, and the light is refracted by the hexagonal prism. Since the hexagonal prism has six faces, a beam of light incident from the focusing tube forms multiple beams of light at the hexagonal prism and irradiates the sewage water surface, and the sewage water surface refracts the light. At this time, the number of light beams is increased and the incidence of light beams is also improved, and the photocatalyst reacts after encountering light. By using the focusing tube and the hexagonal prism together, the reflection law and the refraction law of light are used to change the incidence angle of light and the number of light beams formed, thereby further increasing the contact area between light and the photocatalyst.

[0016] Furthermore, the stirring assembly includes a rotating shaft, which is coaxially fixedly connected to the output shaft of the driving member; and a plurality of stirring rods are fixedly connected to the rotating shaft.

[0017] Beneficial effect: the driving member drives the rotating shaft to rotate, and the rotating shaft drives the stirring rod to rotate to stir the sewage.

[0018] Furthermore, it also includes a gathering component, which includes a sleeve plate, which is fixedly connected to the inner wall of the mixing box; a through groove is opened in the middle of the sleeve plate, and the rotating shaft is located in the through groove and rotates with the through groove; a plurality of through openings are opened on the sleeve plate, and the stirring rods are respectively located in the through openings and rotate with the through openings;

[0019] A main bevel gear is coaxially fixedly connected to the rotating shaft, and the main bevel gear penetrates the top and bottom of the sleeve plate and rotates with the sleeve plate; the top and bottom of the sleeve plate are fixedly connected to the first rod, and the end of the first rod away from the sleeve plate is rotatably matched with the slave bevel gear, and the slave bevel gears are meshed with the main bevel gear; the end of the slave bevel gear away from the first rod is fixedly connected to the vertical rod, and the other end of the vertical rod is fixedly connected to the incomplete gear;

[0021] Beneficial effects: when the driving part is started, the stirring rod rotates at the opening on the sleeve plate; since the main bevel gear is fixedly connected to the rotating shaft, when the rotating shaft rotates, the main bevel gear rotates driven by the rotating shaft, and the slave bevel gear, vertical rod and incomplete gear rotate under the drive of the main bevel gear; since the incomplete gear is engaged with the rack, the incomplete gear at this time drives the rack to move to the right when it rotates, thereby driving the connecting rod and the telescopic rod to move to the right, the telescopic rod extends to cooperate with the movement, and the spring retracts and contracts.

[0022] When the incomplete gear continues to rotate so that its tooth end disengages from the meshing with the rack, the rack loses the driving force of the incomplete gear, and under the elastic restoring force of the spring, the rack moves to the left and resets; thereby driving the connecting rod to deflect to the left, and the telescopic rod contracts to cooperate with the movement; in this process, the connecting rod and the telescopic rod tend to move toward the middle, thereby pushing part of the sewage and dirt to move toward the middle, and when light enters from the water inlet, the photocatalyst located in the middle degrades the organic pollutants in the sewage gathered in the middle under the action of light; the degradation efficiency is improved under the linkage action of the main bevel gear and the rack; the sewage can be discharged through the outlet.

[0023] Furthermore, the support assembly includes a plurality of support legs, one end of each of which is fixedly connected to the bottom of the mixing box.

[0024] Beneficial effect: The mixing box is supported by the supporting legs to prevent the mixing box from directly contacting the ground, thereby reducing the wear on the bottom of the mixing box.

[0025] Furthermore, a reflective component is provided on the outer surface of the stirring rod.

[0026] Beneficial effect: When the stirring rod is rotating, the reflective component on the stirring rod can also reflect light, thereby further increasing the utilization rate of light.

[0028] Beneficial effect: The reflective film is light in weight, and sticking it on the stirring rod will hardly increase the weight of the stirring rod. It is also easy to obtain in life, which improves the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A water outlet 18 is provided on the bottom wall of the mixing box 1 ; a supporting assembly for supporting the mixing box 1 is provided at the bottom of the mixing box 1 .

[0042] The stirring assembly comprises a rotating shaft 8 , which is coaxially fixedly connected to the output shaft of the driving member 2 via bolts; a plurality of stirring rods 10 are welded to the rotating shaft 8 .

[0043] The supporting assembly includes a plurality of supporting legs 3 , one end of each of the supporting legs 3 is welded to the bottom of the mixing box 1 .

[0044] The specific implementation process is as follows:

[0045] The device is placed under sunlight, and sewage and photocatalyst are transported into the collection box 4 and the stirring box 1 through the water inlet. The photocatalyst of this embodiment is titanium dioxide; the driving member 2 is started, and the driving member 2 drives the rotating shaft 8 and the stirring rod 10 to rotate to stir the sewage and the photocatalyst; during stirring, sunlight passes through the focusing plate 6 and the water inlet to irradiate the stirring box 1, and the photocatalytic performance of the photocatalyst is utilized to absorb light energy within the ultraviolet light range, and electrons are excited to generate electron-hole pairs. These electron-hole pairs can participate in the photocatalytic reaction to generate active free radicals with oxidation or reduction ability, thereby promoting the degradation of organic pollutants in the sewage; the stirring action also increases the contact area between light and the photocatalyst.

[0046] Since a focusing tube 20 is provided at the bottom of the focusing plate 6, when light is irradiated into the focusing tube 20, the light is reflected twice by the reflector 19 to the hexagonal prism 7 located below it, and the light is refracted by the hexagonal prism 7. Since the hexagonal prism 7 has six faces, a beam of light incident from the focusing tube 20 forms multiple beams at the hexagonal prism 7 and irradiates the sewage surface, and the sewage surface refracts the light. At this time, the number of light beams is increased and the incidence of light beams is also increased, and the photocatalyst reacts when encountering light. By using the focusing tube 20 and the hexagonal prism 7 together, the law of reflection and the law of refraction of light are used to change the incidence angle of light and the number of light beams formed, thereby further increasing the contact area between light and the photocatalyst.

[0047] The difference between the present invention and the prior art lies in that: photocatalysts are used to degrade organic pollutants in sewage during stirring; in order to increase the effective area of ​​light, the law of reflection of light and the law of refraction of light are used to change the incident angle of light and the number of light beams formed; while stirring, sewage and dirt are gathered so that they are gathered under the light beam, further increasing the effective area of ​​light and photocatalysts, and organic pollutants in sewage can be degraded during the stirring process, thereby improving the efficiency of sewage collection and treatment and achieving the purpose of efficient sewage stirring.

[0055] When the incomplete gear 14 continues to rotate so that its tooth end disengages from the meshing with the rack 17, the rack 17 loses the driving force of the incomplete gear 14, and under the elastic restoring force of the spring 16, the rack 17 moves to the left and resets; thereby driving the connecting rod 15 to deflect to the left, and the telescopic rod 21 contracts to cooperate with the movement; in this process, the connecting rod 15 and the telescopic rod 21 tend to move toward the middle, thereby pushing part of the sewage and dirt to move toward the middle, and when light is emitted from the water inlet, the photocatalyst located in the middle degrades the organic pollutants in the sewage gathered in the middle under the action of light; the degradation efficiency is improved under the linkage action of the main bevel gear 11 and the rack 17; the sewage can be discharged through the water outlet 18.
