Description

Technical Field

[0001] This utility model relates to the field of photocatalytic reaction technology, and in particular to a lamp tube for a parallel photocatalytic reaction apparatus. Background Technology

[0002] In photocatalytic reaction experimental research, parallel photocatalytic reactors must meet the core requirements of simultaneous illumination of multiple reaction flasks and stable reaction environment temperature. However, existing parallel photocatalytic reactor lamps generally suffer from the following technical defects: 1. Integrated structure, difficult maintenance: Most lamps adopt an integrated design with the base and sleeve fixedly connected. When the internal lighting module fails or the inner wall of the sleeve needs to be cleaned, the entire lamp needs to be disassembled, which is cumbersome and easily damages the parts. 2. Lack of temperature monitoring: No dedicated temperature monitoring component is installed, so the temperature of the reaction environment inside the sleeve cannot be obtained in real time. It can only be indirectly inferred from the external ambient temperature. This can easily lead to a decrease in reaction efficiency or deviation in experimental data due to the lag in temperature control. 3. Low heat dissipation efficiency: The heat dissipation structure of the base is mostly a simple metal shell for natural heat dissipation. After long-term use, the heat generated by the light module is easy to accumulate, which not only shortens the life of core components such as LED lights, but may also cause abnormal temperature fluctuations in the reaction system. 4. Low light source utilization: The lighting module lacks an effective light-gathering structure, and the light emitted by the LED lights is easily scattered and lost, resulting in insufficient effective light intensity received by the reaction system in the reaction bottle, which affects the photocatalytic reaction rate. 5. Poor adaptability and high cost: Most existing lamps are designed with a fixed "base-sleeve" assembly. The round hole at the top of the sleeve for placing the reaction flask is of a single size, which can only accommodate reaction flasks of a specific size. When the experiment requires changing to a reaction flask of a different size, the entire lamp or base must be replaced. This not only increases the equipment purchase cost but also reduces experimental efficiency due to the complex replacement process, severely limiting the flexibility of the experimental plan.

[0003] To address the aforementioned technical challenges, there is an urgent need to develop a parallel photocatalytic reactor lamp with a detachable structure, real-time temperature measurement function, efficient heat dissipation system, high light source utilization rate, and the ability to be quickly replaced with a sleeve to adapt to various reaction flasks. Utility Model Content

[0004] According to an embodiment of the present invention, a parallel photocatalytic reactor lamp tube is provided, comprising: The base has a ring-shaped protrusion at its upper end; A sleeve is fitted onto an annular protrusion and is detachably connected to a base via the annular protrusion. The sleeve is hollow and has a probe hole and at least one round hole at its upper end, the round hole being used to place a reaction flask. Temperature probe, installed inside probe hole, is used to detect the temperature inside the sleeve; The lighting module is installed inside the base.

[0005] Furthermore, a pair of first threaded holes are symmetrically arranged on the annular protrusion, and a pair of second threaded holes corresponding to the pair of first threaded holes are arranged on both sides of the lower end of the sleeve. Screws can be installed in the first threaded holes and the second threaded holes to fix the sleeve on the base.

[0006] Furthermore, the base and / or sleeve are made of aluminum.

[0007] Furthermore, the lighting module includes: a light panel, a reflector, a lens, and electrical connectors; The light panel is mounted on the base, and LED lights are installed on the light panel; The reflector is positioned above the light panel, with an opening at the bottom, and the LED light is placed inside the opening. The lens is mounted on top of the reflector; The electrical connector is installed on one side of the base, with one end electrically connected to the lamp panel and the other end connected to an external power source.

[0008] Furthermore, an arc-shaped cooling tank is provided inside the base, and an arc-shaped sealing plate is placed on the upper end of the cooling tank; the cooling tank is connected to an external chiller, and the chiller supplies coolant into the cooling tank.

[0009] Furthermore, a fixing seat is also provided on the sealing plate, and the fixing seat is detachably connected to the base.

[0010] Furthermore, an annular groove is provided on the outer circumference of the fixing seat, and a sealing ring is fitted inside the annular groove to ensure a sealed connection between the fixing seat and the inner wall of the base.

[0011] Furthermore, the lighting module includes: a light panel, a light-transmitting sheet, and electrical connectors; The light panel is mounted on a fixed base, and multiple LED lights are installed on the light panel; The light-transmitting sheet is installed on top of the mounting base; The electrical connector is installed on one side of the base, with one end electrically connected to the lamp panel and the other end connected to an external power source.

[0012] Furthermore, an inlet pipe and an outlet pipe are installed on one side of the base; one end of the inlet pipe is connected to the cooling tank and the other end is connected to an external chiller; one end of the outlet pipe is connected to the cooling tank and the other end is connected to an external chiller.

[0013] Compared with the prior art, the present invention has the following significant advantages: 1. High ease of maintenance: The base and sleeve are detachably connected by threads. Disassembly and assembly only require turning two screws, which is quick. When the light module fails or the sleeve needs to be cleaned, the parts can be quickly separated for maintenance, greatly reducing the difficulty of operation. 2. Precise temperature control: The temperature probe monitors the temperature inside the sleeve in real time, and the data is displayed intuitively through an external temperature controller. Experimenters can adjust the coolant flow rate in a timely manner to avoid temperature fluctuations and ensure a stable reaction environment. 3. Excellent heat dissipation efficiency: The arc-shaped cooling tank, combined with the coolant circulation system and the high thermal conductivity of the aluminum base, can quickly dissipate the heat generated by the lighting module, effectively extending the lifespan of the LED lights. 4. High light source utilization: The combination structure of the reflector cup and plano-convex lens improves the light focusing efficiency of LED light, significantly increases the effective light intensity received by the reaction system, and improves the photocatalytic reaction rate. 5. High adaptability and flexibility: Through the sleeve design of "unified interface + multiple specifications of round holes", different sleeves can be quickly replaced with the same base to adapt to various sizes of reaction bottles without replacing the base or the entire lamp tube, thus reducing equipment procurement costs; the entire sleeve replacement process is short and does not require professional tools, allowing experimenters to adjust it at any time according to experimental needs, greatly improving the equipment's versatility and the flexibility of experimental schemes.

Detailed Implementation

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0017] First, combine Figures 1-15 The lamp tube of the parallel photocatalytic reactor according to the embodiment of the present invention is used in the parallel photocatalytic reactor and has a wide range of applications.

[0018] like Figures 1-15 As shown, the lamp tube of the parallel photocatalytic reactor of this utility model embodiment includes: Base 1, with an annular protrusion 11 at the upper end of base 1; Sleeve 2 is fitted onto an annular protrusion 11 (the annular protrusion 11 is used for positioning sleeve 2) and is detachably connected to base 1 through the annular protrusion 11. Sleeve 2 is hollow and has a probe hole 21 and at least one round hole 22 at its upper end. The round hole 22 is used to place the reaction flask. The diameter and number of round holes 22 can be adjusted according to the size of the reaction flask. At the same time, the round hole 22 plays a positioning role for the reaction flask, so that the position of the reaction flask is fixed each time, thereby ensuring that the initial conditions of each reaction are consistent and improving the accuracy of the experimental results. A temperature probe (existing technology, not shown in the figure) is installed in the probe hole 21 and is used to detect the temperature inside the sleeve 2. Lighting module 3 is installed inside base 1, and the brightness of lighting module 3 is adjustable.

[0019] Furthermore, such as Figure 1 , 4As shown, in this embodiment, a pair of first threaded holes 111 are symmetrically arranged on the annular protrusion 11, and a pair of second threaded holes 23 corresponding to the pair of first threaded holes 111 are arranged on both sides of the lower end of the sleeve 2. Screws can be installed in the first threaded holes 111 and the second threaded holes 23 to fix the sleeve 2 to the base 1. After the sleeve 2 is in place, the screws can be passed through the second threaded holes 23 and screwed into the first threaded holes 111 as needed, so that the sleeve 2 and the base 1 can be detachably fixed. When disassembling, only the screws need to be unscrewed to separate the two, which is convenient for maintaining internal components; at the same time, some experiments can be conducted without screws.

[0020] Furthermore, such as Figure 1 As shown, in this embodiment, the base 1 and / or sleeve 2 are made of aluminum.

[0021] Furthermore, such as Figure 3 As shown, in this embodiment, the lighting module 3 includes: a lamp board 31, a reflector 32, a lens 33, and an electrical connector 34; The light board 31 is mounted on the base 1. The light board 31 is a circular PCB board, which is fixed to the central mounting platform of the base 1 by screws. LED lights are provided on the light board 31. The reflector cup 32 is set above the lamp plate 31 and has an opening at the bottom. The LED light is set inside the opening. The reflector cup 32 is a funnel-shaped component with a high reflectivity aluminum film coated on the inner wall. It is set above the lamp plate 31. The bottom of the reflector cup 32 has an opening adapted to the LED light array. The LED light is fully inserted into the opening, which can reflect the scattered light emitted by the LED light to the top and reduce the lateral loss of light. Lens 33 is a plano-convex lens made of quartz material, which is fixed to the top of the reflector cup 32 by a buckle. The focal point of lens 33 coincides with the center of the LED light array, which can further converge the light reflected by the reflector cup 32 into parallel light, ensuring that the light is vertically and uniformly irradiated into the reaction system in the reaction bottle, thereby improving the utilization rate of the light source. Electrical connector 34 is fixed to the outer wall of base 1. One end of the connector is connected to the power interface of lamp board 31 through a wire, and the other end can be connected to an external DC regulated power supply through a plug to provide a stable power supply for LED lights.

[0022] Furthermore, such as Figures 8-10 As shown in Figure 11, in this embodiment, an arc-shaped cooling tank 12 is provided inside the base 1, and an arc-shaped sealing plate 13 is covered on the upper end of the cooling tank 12. The edge of the sealing plate 13 can be connected to the cooling tank 12 through high-temperature resistant sealant to prevent coolant leakage. The cooling tank 12 is connected to an external chiller, and the chiller introduces coolant into the cooling tank 12.

[0023] Furthermore, such as Figures 6-9As shown, in this embodiment, a fixing seat 14 is also provided on the sealing plate 13. The fixing seat 14 is detachably connected to the base 1 and is used to press the sealing plate 13 to further prevent coolant leakage.

[0024] Furthermore, such as Figure 9 As shown, in this embodiment, an annular groove 141 is also provided on the outer circumference of the fixed base 14, and a sealing ring is fitted inside the annular groove 141 to seal the connection between the fixed base 14 and the inner wall of the base 1, thereby further preventing coolant leakage.

[0025] Furthermore, such as Figures 12-15 As shown, in this embodiment, the lighting module 1 includes: a light panel 31, a light-transmitting sheet 35, and an electrical connector 34; The light panel 31 is mounted on the mounting base 14, and multiple LED lights are provided on the light panel 31; The light-transmitting sheet 35 is installed on the top of the fixed base 14. When there are many circular holes 22, multiple reaction bottles need to be illuminated at the same time. At this time, a single LED light is difficult to meet the experimental requirements. Therefore, the original lens 33 is replaced with a circular light-transmitting sheet 35 with uniform thickness, and the reflector cup 32 is not needed. Electrical connector 34 is installed on one side of base 1, with one end electrically connected to lamp board 31 and the other end connected to an external power source.

[0026] Furthermore, such as Figure 6 , 11 As shown, in this embodiment, an inlet pipe 4 and an outlet pipe 5 are installed on one side of the base 1; one end of the inlet pipe 4 is connected to the cooling tank 12, and the other end is connected to an external chiller; one end of the outlet pipe 5 is connected to the cooling tank 12, and the other end is connected to an external chiller.

[0027] Working principle: 1. External device connection: Connect the inlet pipe 4 and outlet pipe 5 to the external chiller via quick couplings; Connect electrical connector 34 to an external regulated power supply via a plug; Turn on the temperature controller and check if the temperature display is normal (initially displaying the ambient temperature). 2. Experimental preparation and start-up: Add the pre-set reaction system into the reaction flask; Place the reaction flask into the corresponding round hole 22 at the upper end of the sleeve 2, ensuring that the bottom of the reaction flask is directly facing the lens 33 and that the reaction flask is placed stably. Turn on the chiller power, set the coolant flow rate, and check for leaks in the pipes. Turn on the DC regulated power supply, turn on the LED light, and monitor the temperature inside sleeve 2 in real time using the temperature controller; If the temperature exceeds the experimental set value, increase the coolant flow rate of the chiller until the temperature stabilizes within the set range. 3. Sleeve 2 replacement operation (when the reaction flask size needs to be changed in the experiment): Turn off the DC regulated power supply and the chiller, and wait for the equipment to cool to room temperature; Unscrew the screw of the current sleeve 2, hold the upper end of the sleeve 2 and remove the old sleeve 2 vertically upwards; Select a sleeve 2 that fits the size of the new reaction flask, put it on the annular protrusion 11 and screw it in to secure it; Reinsert the temperature probe and secure it, then check the temperature controller display. Reposition the reaction flask according to the steps described above, and start the equipment to continue the experiment. 4. End of Experiment and Equipment Maintenance: Turn off the LED lights and the chiller. After the reaction flask has cooled down, remove it and clean any residual liquid from the reaction flask. If the equipment will not be used for a short period of time, disconnect all external connections, remove sleeve 2 and temperature probe, and wipe the inner wall of sleeve 2, the surface of base 1 and the surface of lens 33 with a lint-free cloth (avoid scratching lens 33).
