Description

Technical Field

[0001] This utility model relates to the field of photocatalytic degradation technology, and in particular to a horizontally inclined solar photocatalytic reaction device. Background Technology

[0002] Wastewater from dyes, pigments, pharmaceuticals, and aquaculture contains a series of organic compounds such as halides, nitro compounds, amino compounds, aniline, and phenols. These pollutants have high concentrations, complex compositions, and high COD. They often contain chromogenic groups, resulting in deep and intense colors. Catalytic oxidation has become a common method for treating wastewater to remove color and reduce COD.

[0003] The common approach involves mixing organic pollutants with catalyst powder, placing the mixture in a reaction vessel such as a flask, beaker, or test tube, and then irradiating it with a specific light source, combined with magnetic stirring within the vessel to achieve photocatalytic degradation of the pollutants. However, powdered catalysts are difficult to recycle, so researchers have developed supported photocatalysts, which are photocatalytic gel beads loaded with catalyst powder. Limited by the strength of the gel beads, traditional magnetic or mechanical stirring can damage the material structure, leading to high catalyst consumption and severely impacting the catalytic effect. Utility Model Content

[0004] The purpose of this invention is to provide a horizontally inclined solar catalytic reaction device that can solve the problem in conventional solutions where the catalyst support is damaged, resulting in the inability to recover the catalyst or the inability to fully exert its catalytic effect.

[0005] The objective of this utility model is achieved through the following technical solution: A horizontally inclined solar catalytic reaction device includes a base plate, a support frame, and at least two rotating cylinders. The support frame is mounted on the base plate for mounting the rotating cylinders. The rotating cylinders are rotatably mounted on the support frame for placing test tubes containing reactants and catalysts, wherein the reactants are dyes. The support frame is provided with a drive mechanism for driving the rotating cylinders to rotate, and the test tubes rotate as the rotating cylinders rotate.

[0006] Preferably, the support frame includes a mounting plate, a support plate, and an upright plate; the mounting plate is installed obliquely on the base plate, and the included angle between the mounting plate and the base plate is 30°-50°; the upright plate is installed vertically on the base plate; the support plate is installed on the top edge of the upright plate; the support plate and the mounting plate are parallel to each other.

[0007] Preferably, the drive drum is mounted on the mounting plate; the drum is mounted between the mounting plate and the support plate; the bottom of the drum has a suitable protrusion so that the two drums do not directly contact each other to ensure good rotation effect, and also so that the test tubes placed on it will not fall off.

[0008] Preferably, the support frame further includes a central reinforcing plate connected between the mounting plate and the upright plate, and two side reinforcing plates disposed on both sides of the central reinforcing plate, with both ends of the side reinforcing plates also connected to the mounting plate and the upright plate.

[0009] Preferably, a reinforcing block is fixedly connected to the side of the upright plate, and the bottom surface of the reinforcing block is fixedly connected to the bottom plate.

[0010] Preferably, the rotating drum is provided with rotating shafts at both ends, and the rotating drum is rotatably connected to the mounting plate and the support plate respectively through the two rotating shafts.

[0011] Preferably, the drive mechanism includes a drive motor, a first synchronous pulley, at least two second synchronous pulleys, and a synchronous belt; the first synchronous pulley is connected to the output end of the drive motor and is driven by the second synchronous pulleys through the synchronous belt.

[0012] Preferably, a motor mount is installed on the side wall of the mounting plate; a limiting frame is fitted on the outer surface of the drive motor, and the bottom surface of the limiting frame is connected to the motor mount by bolts.

[0013] Preferably, the number of second synchronous pulleys is the same as the number of rotating drums; each rotating shaft on each rotating drum is connected to one second synchronous pulley.

[0014] This invention uses a drive mechanism to rotate the drum, allowing test tubes placed between the drums to receive light more evenly. At the same time, the gel bead catalyst inside the test tubes can rotate along with the drums, so that the catalyst on the back side of the test tube can also be illuminated, thus fully activating the catalyst inside the test tube, improving the catalyst's degradation effect on organic pollutants, and reducing damage to the structure of the gel bead material.

[0017] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0018] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand the advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0019] Example 1 This invention uses a drive mechanism 5 to drive the rotating drum 4 to rotate, so that the test tubes placed between the rotating drums 4 can receive light more evenly. This allows the catalyst on the back side of the test tube to also receive light, fully activating the catalyst in the test tube, improving the photocatalytic degradation of organic pollutants, and reducing damage to the catalyst structure.

[0020] A horizontally inclined solar photocatalytic reaction device includes a base plate 10, a support frame, and at least two rotating cylinders 4. The support frame is mounted on the base plate 10 and is used to mount the rotating cylinders 4. The rotating cylinders 4 are rotatably mounted on the support frame and are used to place test tubes containing dyes and photocatalytic gel beads (to prevent the gel beads from clogging inside the test tubes, the gel beads can be strung together with silk thread to form a necklace-like string before being placed inside the test tubes). The support frame is provided with a drive mechanism 5 for driving the rotating cylinders 4 to rotate, and the test tubes rotate as the rotating cylinders 4 rotate.

[0021] In this embodiment, the use of multiple rotating cylinders 4 facilitates the placement of multiple test tubes, with one test tube placed between each two adjacent rotating cylinders 4. The base plate 10 provides overall support for the inclined solar catalytic reaction device, and a rubber pad is provided on the bottom surface of the base plate 10 to prevent the inclined solar catalytic reaction device from being blown away by strong winds. The inclined solar catalytic reaction device can be made of materials such as PLA and PETG, and can be fabricated using 3D printing equipment, making it easy to implement in experiments in schools.

[0022] Furthermore, the support frame includes a mounting plate 1, a support plate 2, and a vertical plate 6; the mounting plate 1 is inclinedly mounted on the base plate 10, with an angle of 30°-50° between the mounting plate 1 and the base plate 10; the vertical plate 6 is vertically mounted on the base plate 10; the support plate 2 is mounted on the top edge of the vertical plate 6; the support plate 2 and the mounting plate 1 are parallel to each other. Setting the inclination angle allows the test tubes to be better placed on the rotating drum 4 to receive sunlight.

[0023] Furthermore, the drive drum 4 is mounted on the mounting plate 1; the drum 4 is mounted between the mounting plate 1 and the support plate 2.

[0024] Furthermore, the support frame also includes a central reinforcing plate 7 connected between the mounting plate 1 and the upright plate 6, and two side reinforcing plates 8 disposed on both sides of the central reinforcing plate 7. The two ends of the side reinforcing plates 8 are also connected to the mounting plate 1 and the upright plate 6.

[0025] Furthermore, a reinforcing block 9 is fixedly connected to the side of the upright plate 6, and the bottom surface of the reinforcing block 9 is fixedly connected to the base plate 10. The upright plate 6, the central reinforcing plate 7, and the reinforcing block 9 all serve to connect and reinforce, improving the overall stress-bearing capacity of the inclined solar catalytic reactor, and preventing the components from breaking or falling apart when the inclined solar catalytic reactor is moved.

[0026] Furthermore, the rotating drum 4 is provided with rotating shafts 3 at both ends, and the rotating drum 4 is rotatably connected to the mounting plate 1 and the support plate 2 respectively through the two rotating shafts 3.

[0027] Furthermore, the drive mechanism 5 includes a drive motor 501, a first synchronous pulley 502, at least two second synchronous pulleys 503, and a synchronous belt 504; the first synchronous pulley 502 is connected to the output end of the drive motor 501 and is connected to the second synchronous pulleys 503 via the synchronous belt 504.

[0028] Furthermore, a motor base 11 is installed on the side wall of the mounting plate 1; a limiting frame 505 is fitted on the outer surface of the drive motor 501, and the bottom surface of the limiting frame 505 is connected to the motor base 11 by bolts.

[0029] Furthermore, the number of the second synchronous pulleys 503 is the same as the number of the rotating drums 4. Each rotating shaft 3 on each rotating drum 4 is connected to one second synchronous pulley 503.

[0030] Working principle: First, place the inclined solar catalytic reaction device under sunlight. Then, place the test tube containing photocatalytic gel beads and dye solution on the rotating drum 4. Start the drive motor 501 to drive the first synchronous wheel 502 to rotate. Under the transmission action of the synchronous belt 504, the second synchronous wheel 503 and the rotating drum 4 will rotate, so that the test tube will rotate. This allows the catalyst inside the test tube to receive sunlight more fully and evenly, improving the efficiency of the dye's catalytic reaction.
