Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a photocatalytic degradation device for organic wastewater. Background Technology

[0002] Photocatalysis is based on the oxidation-reduction ability of photocatalysts under light irradiation to purify pollutants. Photocatalysis is a highly efficient, safe, and environmentally friendly purification technology. Kitchen wastewater and industrial wastewater contain a large amount of organic pollutants and dyes, while agricultural wastewater contains a large amount of organic pesticides. All of these organic wastewaters pollute water bodies and even the soil in which the water is stored, which can lead to damage to human health.

[0003] In the process of wastewater treatment, a photocatalytic degradation device for organic wastewater is required. Chinese utility model patent with announcement number CN220845631U discloses a photocatalytic degradation device for organic wastewater, which includes a base. A control bottle and a reaction bottle are placed sequentially on the upper end of the base. A stopper is inserted into the upper end of both the control bottle and the reaction bottle. A sampling tube is fixedly connected inside the stopper. A reaction component is set on the base. The reaction component includes two rotating motors. Three mounting slots are opened on the upper end of the base. The two rotating motors are fixedly connected in the mounting slots on the left and right sides.

[0004] However, in this novel photocatalytic degradation device for organic wastewater, the magnetic stir bar is placed inside the bottle and driven to rotate by a magnetic disk to achieve stirring. However, when the magnetic stir bar is stirred inside the bottle for a long time, it will rub against the bottom or wall of the bottle, causing wear or loosening, which will affect the stirring effect. Furthermore, there may be deviations in the magnetic field coupling between the magnetic stir bar and the magnetic disk, resulting in uneven stirring and reducing the photocatalytic degradation efficiency. Therefore, a photocatalytic degradation device for organic wastewater is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a photocatalytic degradation device for organic wastewater, which has advantages such as reduced wear and uniform stirring effect, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photocatalytic degradation device for organic wastewater includes a housing, an installation box fixedly connected to the bottom wall of the housing, and a reaction bottle and a control bottle fixedly connected to the top of the installation box. The reaction bottle and the control bottle are each equipped with a stirring structure for stirring the wastewater. The installation box is equipped with a magnetic drive mechanism for operating the stirring structure. An illumination lamp is fixedly installed on the inner wall of the housing.

[0008] The stirring structure includes a piston assembly and a stirring assembly. The stirring assembly includes a rotating seat disposed inside the reaction flask. A connecting shaft extending to the upper surface of the rotating seat is rotatably connected inside the rotating seat. A magnetic fan blade is fixedly connected to the top end of the connecting shaft.

[0009] The magnetic drive mechanism includes a drive motor fixedly installed inside the mounting box and a transmission shaft rotatably connected to the bottom wall of the mounting box. A worm gear is fixedly connected to the output shaft of the drive motor. A worm wheel that meshes with the worm gear is fixedly installed on the outside of the transmission shaft. A turntable is fixedly connected to the top of the transmission shaft, and a magnet is fixedly connected to the top of the turntable.

[0010] Furthermore, the piston assembly includes a piston cylinder fixedly connected to the bottom wall of the reaction flask, a stopper plate slidably connected inside the piston cylinder, a stopper rod extending to the upper surface of the piston cylinder fixedly connected to the top of the stopper plate, and a rotating seat fixedly connected to the top of the stopper rod.

[0011] Furthermore, the magnetic fan blade is rotatably connected to the top of the piston cylinder, and a return spring is fixedly connected between the piston cylinder and the rotating seat.

[0012] Furthermore, the reset spring is connected to the outside of the stopper rod, the stopper rod is slidably connected to the inside of the piston cylinder and extends to its upper surface, and the left and right sides of the piston cylinder are respectively fixedly connected to the inlet pipe and the outlet pipe.

[0013] Furthermore, there are two sets of stirring structures, which are sequentially distributed inside the reaction flask and the control flask.

[0014] Furthermore, both the turntable and the magnet are rotatably connected to the inside of the mounting box and located on the lower surface of the magnetic fan blades, and there are two sets of magnetic drive mechanisms.

[0015] Furthermore, there are multiple light lamps, which are sequentially distributed inside the box and surround the outside of the reaction bottle and the control bottle.

[0016] Furthermore, both the reaction flask and the control flask are equipped with sampling tubes that extend to the outside of the chamber, and both the reaction flask and the control flask are transparent glass bottles.

[0017] Compared with the prior art, this utility model provides a photocatalytic degradation device for organic wastewater, which has the following beneficial effects:

[0018] 1. This photocatalytic degradation device for organic wastewater uses magnetic fan blades that rotate at the top of the piston cylinder. Combined with the inlet and outlet functions of the piston assembly, the magnetic fan blades can move up and down while rotating, which can more evenly stir the wastewater and photocatalyst in the reaction bottle and control bottle. This achieves three-dimensional stirring of the wastewater, improves the stirring effect, ensures that the wastewater and photocatalyst are fully mixed, accelerates the photocatalytic reaction, and achieves the advantages of reduced wear and uniform stirring effect.

[0019] 2. This photocatalytic degradation device for organic wastewater uses magnetic fan blades that are driven by magnetic force to rotate, without direct contact with the bottom of the container, thus extending the service life of the stirring components. By adjusting the speed of the drive motor, the rotation speed of the magnet can be changed, thereby indirectly adjusting the rotation speed of the magnetic fan blades, adapting to the stirring requirements of wastewater with different viscosities, and improving the accuracy and reliability of the experiment.

[0025] 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.

[0026] Please see Figures 1 to 4The photocatalytic degradation device for organic wastewater in this embodiment includes a box 1, an installation box 2 fixedly connected to the bottom wall of the box 1, and a reaction bottle 3 and a control bottle 4 fixedly connected to the top of the installation box 2 respectively. The reaction bottle 3 and the control bottle 4 are both provided with a stirring structure 6 for stirring the wastewater. The installation box 2 is provided with a magnetic drive mechanism 7 for operating the stirring structure 6. A light lamp 5 is fixedly installed on the inner wall of the box 1.

[0027] The stirring structure 6 includes a piston assembly and a stirring assembly. The stirring assembly includes a rotating seat 64 disposed inside the reaction flask 3. A connecting shaft 66 extending to its upper surface is rotatably connected inside the rotating seat 64. A magnetic fan blade 67 is fixedly connected to the top of the connecting shaft 66. The magnetic fan blade 67 rotates by magnetic force and does not directly contact the bottom surface of the container, thus avoiding the wear problem caused by long-term stirring of traditional stir bar, extending the service life of the stirring component and reducing equipment maintenance costs.

[0028] Specifically, the piston assembly includes a piston cylinder 61 fixedly connected to the bottom wall of the reaction flask 3. A stopper plate 62 is slidably connected inside the piston cylinder 61. A stopper rod 63 extending to the upper surface of the piston cylinder 61 is fixedly connected to the top of the stopper plate 62. A rotating seat 64 is fixedly connected to the top of the stopper rod 63. A magnetic fan blade 67 rotates on the top of the piston cylinder 61. Combined with the liquid inlet and outlet functions of the piston assembly, this allows the wastewater to flow and mix more thoroughly in the reaction flask 3 and the control flask 4, improving the stirring effect and thus enhancing the photocatalytic degradation efficiency.

[0029] It should be noted that the magnetic fan blade 67 is rotatably connected to the top of the piston cylinder 61, and a return spring 65 is fixedly connected between the piston cylinder 61 and the rotating seat 64. The return spring 65 is connected around the outside of the stopper rod 63, which is slidably connected inside the piston cylinder 61 and extends to its upper surface. The left and right sides of the piston cylinder 61 are respectively fixedly connected to the inlet pipe 68 and the outlet pipe 69. The return spring 65 between the piston cylinder 61 and the rotating seat 64 can provide a buffer for the up and down movement of the stopper rod 63 during the stirring process, reducing the impact of water flow impact or equipment vibration, and ensuring that the stopper rod 63 can return to its original position after stirring, so that the stirring structure 6 maintains a stable working state.

[0030] In addition, there are two sets of stirring structures 6, which are distributed sequentially inside the reaction flask 3 and the control flask 4.

[0031] Please see Figure 1 and Figure 4In this embodiment, the magnetic drive mechanism 7 includes a drive motor 71 fixedly installed inside the mounting box 2 and a transmission shaft 73 rotatably connected to the bottom wall of the mounting box 2. A worm gear 72 is fixedly connected to the output shaft of the drive motor 71, and a worm wheel 74 meshing with the worm gear 72 is fixedly installed on the outside of the transmission shaft 73. A turntable 75 is fixedly connected to the top of the transmission shaft 73, and a magnet 76 is fixedly connected to the top of the turntable 75. By adjusting the rotational speed of the drive motor 71, the rotational speed of the magnet 76 can be changed, thereby indirectly adjusting the rotational speed of the magnetic fan blade 67 to meet the stirring requirements under different reaction conditions, such as adjusting the stirring speed according to the concentration and viscosity of the wastewater. By using the transmission of the worm gear 72 and the worm wheel 74, the transmission ratio is large, the transmission is smooth, and the self-locking is good, which can ensure the stable rotation of the magnet 76, thereby ensuring the stable stirring of the magnetic fan blade 67 and reducing the problem of uneven stirring caused by unstable transmission.

[0032] The turntable 75 and the magnet 76 are rotatably connected to the inside of the mounting box 2 and are located on the lower surface of the magnetic fan blade 67. There are two sets of magnetic drive mechanisms 7.

[0033] Specifically, there are multiple light lamps 5, which are sequentially distributed inside the housing 1 and surround the outside of the reaction bottle 3 and the control bottle 4. The device simultaneously sets up the reaction bottle 3 and the control bottle 4, allowing for comparative experiments under the same conditions. By comparing the degradation effects of wastewater in the two bottles, the performance of the photocatalytic degradation process and the optimization parameters can be more accurately evaluated, providing a more reliable basis for actual wastewater treatment.

[0034] It should be noted that both reaction flask 3 and control flask 4 have sampling tubes 8 inserted inside, extending to the outside of the housing 1. Both reaction flask 3 and control flask 4 are transparent glass bottles. Both reaction flask 3 and control flask 4 are fixedly connected to inlet and outlet tubes.

[0035] The working principle of the above embodiments is as follows:

[0036] In use, wastewater is injected into reaction bottle 3 and control bottle 4 respectively. Photocatalyst is added to reaction bottle 3. The controller starts the drive motor 71, whose output shaft drives the worm gear 72 to rotate. This, in turn, drives the transmission shaft 73 to rotate via the worm wheel 74, which in turn drives the turntable 75 and magnet 76 to rotate. Since magnet 76 is located on the lower surface of the magnetic fan blade 67, the magnetic field generated by its rotation interacts with the magnetic fan blade 67, driving it to rotate and thus agitating the wastewater. Wastewater can enter piston cylinder 61 through inlet pipe 68. During agitation, the stopper plate 62 can adjust according to changes in internal pressure. The piston cylinder 61 slides inside, and the stirred wastewater can be discharged through the drain pipe 69. A return spring 65 is fixedly connected between the piston cylinder 61 and the rotating seat 64, which surrounds the stopper rod 63. The return spring 65 can provide buffering and reset for the up and down movement of the stopper rod 63. Multiple light lamps 5 surround the outside of the reaction bottle 3 and the control bottle 4 on the inner wall of the box 1 to provide light conditions for the photocatalytic reaction and promote the degradation of organic wastewater by the photocatalyst. Sampling tubes 8 extending to the outside of the box 1 are inserted inside the reaction bottle 3 and the control bottle 4. During the reaction, the reaction progress and effect can be detected at any time through the sampling tubes 8.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
