Description

Technical Field

[0001] The present invention relates to the technical field of photoreaction, in particular to a photoreactor device. Background Art

[0002] A photoreactor is a reaction vessel designed specifically for photochemical reactions. It uses a light source of a specific wavelength (such as ultraviolet light, visible light, or near-infrared light) to activate photosensitizers or catalysts in the reaction medium, generating free radicals or excited molecules, which in turn trigger a series of chemical reactions. Because of its advantages of high efficiency, high selectivity and environmental protection, photoreactor devices are widely used in the fields of chemistry, biomedicine, environmental science and teaching experiments; When a photoreactor device decomposes compounds in waste liquid, it is basically directly irradiated and decomposed by a single ultraviolet light. Because a single direct irradiation can only irradiate and decompose the waste liquid at the same position, it will result in low decomposition efficiency of the waste liquid compounds and poor practicality. To overcome the above-mentioned drawbacks, prior art 1 (application number CN202322474024.8, Chinese patent application date 2023-09-12) provides a photoreactor that, through the specific configuration of the photoreaction group, changes the problem of the traditional photoreactor obtaining light in a one-way manner. Two reaction vessels with complementary directions are set as a photoreaction group. Liquid enters the photoreaction group from both ends. At any position, light will sequentially pass through the parts with low and high cell concentrations in the photoreaction group, thereby improving the utilization rate of light and increasing the reaction rate. There is also prior art 2 (Chinese patent application number CN202220077734.X, application date 2022-01-12) in which a photoreactor has a reaction speed of seconds compared to existing equipment, and the light energy utilization rate is 5 to 8 times higher. The light source can switch between blue light and ultraviolet light, and can be used for both photocatalysis and photolysis, with strong versatility. The LED array lamp module is equipped with a heat dissipation device to reduce the main heat source and effectively reduce the heat inside the closed cavity; And prior art 3 (Chinese patent application number CN201921519490.0, application date 2019-09-12) in a photoreactor with a replaceable light source, a COB planar light source is provided on the LED light source board, and the depth of the planar light source is not less than the depth of the groove for placing the reaction container, so that the substance at the bottom of the reaction container can also fully react, and the COB planar light source is a surface-emitting light source with higher power and uniform light emission, while ensuring uniform irradiation of the reactants in the reaction container, making the light reaction stable; Although the existing technology can improve the utilization rate of the light source to improve the decomposition efficiency of the waste liquid compound and is more practical, it does not have a quantitative conveying mechanism to quantitatively convey the waste liquid during the waste liquid transportation. As a result, the waste liquid is directly transported to the interior of the machine body, which reduces the efficiency of the light reaction and the decomposition efficiency of the waste liquid compound. Therefore, we propose a photoreactor device to solve the above problems. Summary of the Invention

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0017] The present invention provides the following technical solutions: Embodiment 1 is to solve the problem that, in the prior art, a quantitative conveying mechanism is not provided to quantitatively convey the waste liquid during the waste liquid conveying process, which results in the waste liquid being directly conveyed into the interior of the body 1, thereby reducing the efficiency of the photoreaction and the decomposition efficiency of the waste liquid compounds. The following is disclosed: The fuselage 1 and the feed pipe 2, wherein the feed pipe 2 is installed through the top outer side of the fuselage 1 through a slotted seal, and the bottom end of the feed pipe 2 extends through the inner side of the fuselage 1, and the exhaust valve 6 is installed through the slotted seal on the top right side of the fuselage 1; A circle of support legs 5 is screwed onto the outer side of the bottom of the body 1, and the support legs 5 are arranged at equal angles. A processing box 3 is installed in a circular groove seal at the bottom of the body 1, and a discharge valve 4 is installed through the groove seal at the bottom of the processing box 3. The device further comprises: a control panel 8 is screwed onto the top front side of the body 1, and the control panel 8 is connected to an external controller via a central processing module, and a display screen 7 is provided at the bottom of the control panel 8, and the display screen 7 is slotted and arranged on the front side of the body 1; The inner wall of the body 1 is coated with a reflective coating 13 made of metal material, and a row of concave lenses 12 are positioned and installed on both sides of the inner wall of the body 1, and the two rows of concave lenses 12 are both inclined; An ultraviolet lamp 10 is positioned and installed inside the feed tube 2, and a circle of optical fiber 11 is correspondingly arranged on the outside of the ultraviolet lamp 10, and another circle of optical fiber 11 is arranged at equal angles on the inner wall of the feed tube 2; A sealing plate 23 is installed through the slotted seal on the top inner side of the feed pipe 2, and the left end of the sealing plate 23 slides and extends to the outside of the left end of the feed pipe 2, and a push plate 22 is positioned and connected to the outside of the left end of the sealing plate 23.

[0018] A first return spring 24 is provided in a groove on the inner top side of the fuselage 1, and the outer end of the first return spring 24 is connected to a push plate 22. The push plate 22 is slidably installed on the inner top side of the fuselage 1, and the top end of the push plate 22 is trapezoidal in shape.

[0019] A driving motor 9 is screw-mounted on the top left side of the fuselage 1 , and an output end of the driving motor 9 is connected to a rotating shaft 14 , and the rotating shaft 14 is rotatably mounted on the top left side of the fuselage 1 .

[0020] An eccentric wheel 15 is installed on the outer side of the rotating shaft 14 , and a push plate 22 is closely connected to the outer side of the eccentric wheel 15 .

[0021] The top end of the rotating shaft 14 is connected to a single-rotation reciprocating screw 17 through a first transmission assembly 16, and the single-rotation reciprocating screw 17 is rotatably installed on the top inner side of the fuselage 1, and the bottom outer side of the single-rotation reciprocating screw 17 is threadedly connected to a cleaning seat 18, and the inner side slot of the cleaning seat 18 is slidably connected to the feed pipe 2.

[0022] like Figure 1-Figure 7 As shown, while the waste liquid is being transported, the waste liquid from the outside is transported to the inside of the fuselage 1 through the feed pipe 2. At this time, the ultraviolet lamp 10 and the optical fiber 11 arranged inside the feed pipe 2 are started to emit light through the control panel 8. At this time, the reflective coating 13 and the two rows of concave lenses 12 arranged on the inner wall of the fuselage 1 will simultaneously focus the generated light source, strengthen the ultraviolet light beam, maximize the reuse of light to repeatedly pass through the waste liquid, improve the light reaction efficiency, and improve practicality.

[0023] Restart the drive motor 9 to drive the rotating shaft 14 to rotate, and then the eccentric wheel 15 installed through the outer end of the rotating shaft 14 will simultaneously hit the sealing plate 23 set at the outer end of the push plate 22 to move back and forth on the top inner side of the feed pipe 2, and then use the elastic force of the first return spring 24 itself to elastically reset the position of the push plate 22 after movement, so that the waste liquid transported inside the feed pipe 2 can be quantitatively transported through the sealing plate 23, avoiding the waste liquid being directly transported to the inside of the fuselage 1 and affecting the reaction efficiency of the light beam, and the operation is more time-saving and labor-saving.

[0024] While the rotating shaft 14 rotates, the first transmission assembly 16 connected to its top will simultaneously drive the single-rotation reciprocating screw 17 to rotate, and then the cleaning seat 18 connected by the outer thread of the single-rotation reciprocating screw 17 will move up and down to wipe the waste liquid impurities stuck on the outer surface of the feeding tube 2, so as to prevent the waste liquid impurities from sticking to the outer surface of the feeding tube 2 and affecting the efficiency of the subsequent light reaction, thereby improving the utilization rate of the light beam and increasing the reaction rate.

[0025] The second embodiment differs from the first embodiment in that the two main stirring rods 19 can be driven to drive two rows of auxiliary stirring rods 20 to mix and stir the incoming waste liquid while the rotating shaft 14 rotates, thereby improving the decomposition efficiency of the waste liquid compounds and improving practicality. The bottom end of the rotating shaft 14 is connected to the main stirring rod 19, and the main stirring rods 19 are rotatably installed at both ends of the bottom of the fuselage 1, and the top end of the left main stirring rod 19 is connected to the rotating shaft 14, and the bottom end of the left main stirring rod 19 extends through to the outside of the bottom of the fuselage 1.

[0027] like Figures 1-9 As shown, while the rotating shaft 14 rotates, the main stirring rod 19 connected to its bottom end will also rotate at the same time, because the two main stirring rods 19 are connected by the second transmission assembly 21. At this time, a row of auxiliary stirring rods 20 arranged at the outer ends of the two main stirring rods 19 mix and stir the waste liquid transported in, so as to improve the photoreaction efficiency of the waste liquid in the later stage, and have better practicality.

[0028] The third embodiment is different from the second embodiment in that the cleaning scraper 27 provided at the bottom end of the moving rod 26 can be driven to move back and forth to clean the waste liquid impurities stuck on the surface of the filter screen plate 28 while the main stirring rod 19 rotates, thereby preventing the waste liquid impurities from sticking to the surface of the filter screen plate 28 and affecting the subsequent discharge and use. A beating block 25 is installed through the bottom of the left main stirring rod 19, and a moving rod 26 is correspondingly installed on the outside of the beating block 25. The moving rod 26 is slidably installed inside the processing box 3 through a second return spring 29.

[0029] A cleaning scraper 27 is positioned and installed at the bottom end of the moving rod 26, and the bottom of the cleaning scraper 27 is fitted with a filter screen plate 28, and the filter screen plate 28 is screwed installed on the bottom inner side of the processing box 3, and the bottom of the filter screen plate 28 corresponds to the discharge valve 4.

[0030] like Figures 1-8 As shown, while the left-end main stirring rod 19 rotates, the beating block 25 arranged at the bottom of the left-end main stirring rod 19 will simultaneously beat the cleaning scraper 27 installed at the bottom of the moving rod 26 to move and clean the waste liquid impurities stuck on the surface of the filter screen plate 28, so as to prevent the waste liquid impurities from sticking to the surface of the filter screen plate 28 and affecting the discharge of waste liquid in the later stage. Finally, the elastic force of the second reset spring 29 itself can be used to reset the moving rod 26 that is beating, so as to realize the reciprocating movement of the waste liquid impurities stuck on the surface of the filter screen plate 28, which saves time and effort, thereby completing a series of tasks.
