Abstract
Description
Technical Field
[0001] This utility model relates to the field of photocatalyst addition technology, specifically to a photocatalyst addition system. Background Technology
[0002] Photocatalysts are important catalysts in the process of photocatalytic oxidation treatment of wastewater. For example, some semiconductor quantum dots or organometallic complexes are dissolved in wastewater as liquid photocatalysts. Under light conditions, they initiate a series of redox reactions to degrade pollutants in wastewater. Compared with solid photocatalysts, liquid photocatalysts have better dispersibility and contact effect with pollutants, and exhibit higher catalytic activity in certain specific wastewater treatment scenarios.
[0003] Liquid catalysts are generally formed by dissolving or dispersing photocatalytic active substances in a suitable solvent. In wastewater treatment, liquid catalysts are usually added to the wastewater through a feed pipe. However, during the process of adding photocatalysts through the feed pipe, the photocatalysts tend to adhere to the inner wall of the feed pipe, which affects the accuracy of the photocatalyst addition and thus the wastewater treatment effect.

The support plate is located on one side of the support frame, and multiple support columns are fixedly mounted on the support plate. The support columns pass through the support plate and are fixedly connected to the storage tank. The support columns are slidably connected to the support plate. The weight sensor is fixedly located between the support plate and the support frame. A microcontroller is mounted on the weight sensor and is electrically connected to both the weight sensor and the electronic pipeline control valve. The rinsing mechanism is located between the support frame and the dosing hose and is used to rinse the photocatalyst adhering to the inner wall of the dosing hose. The mixing mechanism is located inside the storage tank and is used to mix the photocatalyst and solvent within the storage tank.
[0006] Preferably, the rinsing mechanism includes:
[0007] Mounting plate, the mounting plate being fixedly mounted on the support frame;
[0008] A water pump is mounted on the mounting plate. The water pump input is connected to an external pure water source, and the water pump output is connected to the end of the dosing hose near the storage tank.
[0009] Furthermore, the mixing mechanism includes:
[0010] The first cavity is formed inside the top wall of the liquid storage tank;
[0011] A positioning post is rotatably mounted on the inner top wall of the first cavity, and the end of the positioning post away from the support plate extends through the inner bottom wall of the first cavity into the liquid storage tank.
[0012] A mixing column, wherein the positioning column has multiple second cavities, the mixing column is rotatably mounted on both sides of the positioning column sidewall located on the second cavity, and multiple mixing rods are fixedly mounted on the sidewall of the mixing column.
[0013] A first rotating mechanism is disposed on the liquid storage tank and is used to drive the positioning column to rotate;

[0015] Furthermore, the first rotating mechanism includes:

[0025] The working principle and beneficial effects of this utility model are as follows:
[0026] 1. In this utility model, the rinsing mechanism facilitates the addition of pure water to the dosing hose after the photocatalyst is added to the wastewater through the dosing hose. This allows the pure water to wash the photocatalyst adhering to the inner wall of the dosing hose into the wastewater, thereby improving the dosing accuracy of the photocatalyst.

In this utility model, by setting up a dosing hose, a support plate, a weight sensor, a rinsing mechanism, and a mixing mechanism, it is convenient to use pure water to flush the photocatalyst attached to the dosing hose into the wastewater when adding liquid photocatalyst. This solves the problem in the prior art that the dosing accuracy is easily affected by the photocatalyst adhering to the inner wall of the pipe during the dosing of photocatalyst through the pipeline.

Detailed Implementation
[0037] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0038] like Figures 1-5 As shown, this embodiment proposes a photocatalyst dosing system, including a support frame 1 and a storage tank 2. The storage tank 2 is located on one side of the support frame 1, and an inlet is provided on the side wall of the storage tank 2. It also includes a dosing hose 3, a support plate 5, a weight sensor 7, a rinsing mechanism, and a mixing mechanism. The dosing hose 3 is connected to the bottom side wall of the storage tank 2, and an electronic pipeline control valve 4 is installed on the dosing hose 3. The support plate 5 is located on one side of the support frame 1, and multiple support columns 6 are fixedly installed on the support plate 5. The support columns 6 pass through the support plate 5 and are fixedly connected to the storage tank 2. The support columns 6 are slidably connected to the support plate 5. The weight sensor 7 is fixedly installed between the support plate 5 and the support frame 1. A microcontroller is installed on the weight sensor 7, and the microcontroller is electrically connected to the weight sensor 7 and the electronic pipeline control valve 4. The rinsing mechanism is located between the support frame 1 and the dosing hose 3 and is used to rinse the photocatalyst adhering to the inner wall of the dosing hose 3. The mixing mechanism is located inside the storage tank 2 and is used to mix the photocatalyst and solvent inside the storage tank 2.
[0039] Reference Figure 1 and Figure 2The rinsing mechanism includes a mounting plate 8 and a water pump 9. The mounting plate 8 is fixedly mounted on the support frame 1, and the water pump 9 is mounted on the mounting plate 8. The input end of the water pump 9 is connected to an external pure water source, and the output end of the water pump 9 is connected to the end of the dosing hose 3 near the storage tank 2. Specifically, after adding the photocatalyst to the wastewater through the dosing hose 3, pure water can be added to the dosing hose 3 through the operation of the water pump 9. This facilitates the rinsing of the photocatalyst adhering to the inner wall of the dosing hose 3 into the wastewater through the pure water, thereby improving the dosing accuracy of the photocatalyst. At the same time, the addition of pure water to the wastewater will not affect the wastewater treatment.
[0040] To address the issue of sedimentation that easily occurs in liquid photocatalysts after standing, refer to Figures 3-5 The mixing mechanism includes a first cavity, a positioning column 10, a mixing column 11, a first rotating mechanism, and a second rotating mechanism. The first cavity is located inside the top wall of the storage tank 2. The positioning column 10 is rotatably mounted on the inner top wall of the first cavity. One end of the positioning column 10, away from the support plate 5, extends through the inner bottom wall of the first cavity into the storage tank 2. Multiple second cavities are provided inside the positioning column 10. Mixing columns 11 are rotatably mounted on both sides of the second cavity of the positioning column 10. Multiple mixing rods are fixedly mounted on the side walls of the mixing columns 11. The first rotating mechanism is mounted on the storage tank 2 and is used to drive the positioning column 10 to rotate. The second rotating mechanism is located inside the second cavity and is used to drive the mixing column 11 to rotate. The first rotating mechanism includes a first toothed ring 12, a first... Gear 13 and first motor 14, first gear ring 12 are fixedly mounted on positioning post 10, first gear 13 are rotatably mounted in first cavity, first gear 13 meshes with first gear ring 12, first motor 14 is mounted on storage tank 2, first motor 14 output end is fixedly connected to first gear 13. Specifically, when photocatalyst is not added, the operator controls the first motor 14 to work, the operation of the first motor 14 can drive the first gear 13 to rotate, and at the same time, the meshing of the first gear 13 with the first gear ring 12 can drive the positioning post 10 to rotate, so that the rotation of the positioning post 10 can drive the mixing post 11 and mixing rod to mix the liquid photocatalyst, thereby avoiding sedimentation of the liquid photocatalyst.
[0041] Reference Figures 3-5The second rotating mechanism includes a positioning port, a first bevel gear 15, a second bevel gear 16, and a positioning rod 17. A positioning port is provided on the inner top wall of the second cavity, penetrating the positioning post 10. The first bevel gear 15 is rotatably mounted on one end of the second cavity near the mixing post 11, and is fixedly connected to the mixing post 11. The second bevel gear 16 is rotatably mounted on the inner top wall of the second cavity, meshing with the first bevel gear 15. The positioning rod 17 is fixedly mounted on the inner top wall of the first cavity, penetrating the positioning port and fixedly connected to the second bevel gear 16. The positioning post 10... Multiple scrapers 18 are fixedly installed, and the scrapers 18 are in contact with the inner wall of the storage tank 2. Specifically, during the rotation of the positioning column 10, the first bevel gear 15 can be driven to move around the second bevel gear 16. At the same time, the second bevel gear 16 does not rotate under the limitation of the positioning rod 17. Therefore, the meshing of the second bevel gear 16 and the first bevel gear 15 can drive the first bevel gear 15 and the mixing column 11 to rotate, thereby allowing the mixing rod to move around the mixing column 11, thereby further improving the mixing effect of the liquid photocatalyst and further improving the dosing accuracy of the photocatalyst.
[0042] In this embodiment, during use, the operator connects the dosing hose 3 to the wastewater treatment equipment. Then, the operator opens the electronic pipeline control valve 4, allowing the photocatalyst in the storage tank 2 to enter the wastewater through the dosing hose 3 and participate in wastewater treatment. Simultaneously, the weight sensor 7 detects the weight of the storage tank 2 and the entire liquid photocatalyst during the dosing process, facilitating timely closure of the electronic pipeline control valve 4 when adding a measured amount of liquid photocatalyst. This ensures precise metering of the liquid photocatalyst. After adding the photocatalyst to the wastewater through the dosing hose 3, the water pump 9 adds purified water to the dosing hose 3. This allows the purified water to wash the photocatalyst adhering to the inner wall of the dosing hose 3 into the wastewater, improving the dosing accuracy. Furthermore, the addition of purified water does not affect wastewater treatment. After the initial mixing is complete, the operator controls the first motor 14 to operate. The operation of the first motor 14 drives the first gear 13 to rotate. Simultaneously, the meshing of the first gear 13 with the first gear ring 12 drives the positioning column 10 to rotate. This rotation of the positioning column 10 drives the mixing column 11 and the mixing rod to mix the liquid photocatalyst, thus preventing sedimentation of the liquid photocatalyst. During the rotation of the positioning column 10, the first bevel gear 15 can be driven to move around the second bevel gear 16. The second bevel gear 16 does not rotate under the limitation of the positioning rod 17. Therefore, the meshing of the second bevel gear 16 with the first bevel gear 15 drives the first bevel gear 15 and the mixing column 11 to rotate, thereby allowing the mixing rod to move around the mixing column 11, further improving the mixing effect of the liquid photocatalyst and thus further improving the dosing accuracy of the photocatalyst.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
