Description

Technical Field

[0001] The utility model belongs to the field of chemical experimental instruments and relates to a multifunctional photocatalytic reaction device. Background Art

[0002] Photocatalytic reactions are widely used in the field of chemical experiments, but existing photocatalytic reaction devices will cause light refraction during the photocatalytic process, which causes the energy of the light source to not be fully concentrated in the effective area of ​​the reaction system. Part of the light energy is lost due to refraction, reducing the utilization rate of light energy. Secondly, the processing capacity of liquid samples by traditional photocatalytic reaction devices is relatively limited. When processing solid samples, it is often difficult for solid samples to obtain uniform illumination, resulting in uneven distribution of catalyst activity during the reaction, affecting the uniformity and efficiency of the reaction; when there are fewer liquid samples, the contact area between the photocatalyst and the reactants is limited, resulting in reduced reaction efficiency, which is not conducive to large-scale processing or industrial applications. Therefore, it is necessary to design a multifunctional photocatalytic reaction device to solve these problems. Summary of the invention

[0003] The utility model aims to provide a multifunctional photocatalytic reaction device to solve the problems of low efficiency, uneven irradiation of solid samples, and small amount of liquid sample processing in traditional photocatalytic reaction devices.

[0004] The technical solution adopted by the utility model to solve its technical problems is: the solid sample holder is fixed on the bottom plate by the outer groove of the hexagonal prism, the solid sample is fixed by the sample clamp on the solid sample holder, and the rebound device pulls it to be flat to achieve uniform irradiation. For liquid samples, the liquid sample pool is fixed on the groove of the prism by the protrusions on both sides, and the size of the protrusions is adapted to the groove. The liquid sample and the magnetic stirrer are placed in the sample pool, and the liquid sample is stirred by rotation. A light beam is introduced, and filters of different types filter light of different wavelengths, which are accurately irradiated on the sample to start the reaction. The surface of the liquid sample pool close to the light column is set to be arc-shaped, and the position and arc are concentric with the light column, which ensures that the light emitted by the light column is vertically incident on the sample pool without refraction, so that the sample is irradiated more efficiently. After the reaction is completed, the solid sample holder or liquid sample pool is removed for cleaning and the sample is preserved.

[0005] The beneficial effects of the utility model are: 1. When the device is used for photocatalytic reaction, only light of the required wavelength can be transmitted to achieve precise irradiation; 2. When the device is used to irradiate solid samples, the samples can be fixed and flattened, and the polymer materials can be evenly irradiated to measure their aging and photodegradation under light; 3. The liquid sample pool of the device can be disassembled for easy cleaning and maintenance. The liquid sample pool has a large volume and can be equipped with a magnetic stirrer; the surface of the liquid sample pool close to the light column is arranged in an arc shape to ensure that the light emitted by the light column enters the sample pool vertically without refraction, so that the sample irradiation is more efficient.

[0013] The base of the prism is a regular hexagon, symmetrically distributed around the light column and fixed on the bottom plate. The opposite faces of two adjacent prisms are parallel to each other and have two grooves. The inner groove close to the light column is used to fix the filter, and the outer groove is used to fix the solid sample holder or the liquid sample pool.

[0014] The liquid sample pool is fixed on the groove of the prism through protrusions on both sides, the size of the protrusions is adapted to the groove, and the sample pool can be disassembled after use; the surface of the liquid sample pool close to the light column is arranged in an arc shape, and the position and arc are concentric with the light column, ensuring that the light emitted by the light column is vertically incident on the sample pool without refraction, so that the sample is irradiated more efficiently.

[0015] The solid sample holder is provided with protrusions on both sides, which can fix the solid sample holder in the groove of the prism. The solid sample holder includes a rebound device and a solid sample clamp. The upper and lower sample clamps can fix the solid sample in the shape of a film, and the rebound device can straighten the sample to make the solid sample flatter.

[0016] The optical filter can be replaced, and different types of optical filters can be used to filter light of different wavelengths, so that only light of the required wavelength is transmitted, thereby achieving precise irradiation.

[0017] A magnetic stirrer is arranged on the bottom plate below the liquid sample pool to accelerate the reaction by stirring.

[0018] The liquid sample pool can be made of transparent materials such as quartz and glass.

[0019] The sample pool material, except for the liquid sample pool, can be made of plastic, metal, ceramic and other materials.

[0020] Instructions for use: For solid samples, fix the solid sample holder in the groove of the prism through the protrusions on both sides, fix the sample with the sample clamp, and pull it flat with the rebound device to achieve uniform irradiation.
