Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a dual-wavelength light source derivatizer with a derivatization pipeline that can be quickly replaced. Background Art

[0002] Aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2 in a sample are extracted with a mixed solution of acetonitrile-aqueous solution or methanol-aqueous solution. The extract is purified and enriched by an immunoaffinity column. After the purified solution is concentrated, fixed in volume, and filtered, it is separated by liquid chromatography, post-column photochemical derivatization, passed through a fluorescence detector, and the concentration is measured.

[0003] For existing post-column photochemical derivatization instruments, the light source mostly uses a single-wavelength ultraviolet light source within the wavelength range of 254 - 405 nm. The derivatization pipeline adopts a form of winding the pipeline back and forth with fixed struts at both ends or a form of winding the pipeline around the outside and inside with a transparent material as a support. The mixing degree of the liquid inside the pipeline is poor. At the same time, some transparent materials have absorbability to ultraviolet light and low transmittance, resulting in poor derivatization effect. Due to the pipe-winding method, when the derivatization pipeline has problems and needs to be replaced, the pipeline needs to be removed and then rewound, wasting labor. When the light intensity of the light source of the derivatization instrument becomes weak or the service life has problems, resulting in a weakened derivatization effect, it cannot be monitored in time. When the derivatization pipeline leaks liquid, resulting in the failure of the derivatization effect, it cannot be monitored in time. After the derivatization instrument has worked for a long time, if the labor is busy or at night, the derivatization instrument cannot be turned off in time, resulting in a waste of the light source life and an increase in the electricity cost. Due to the long-term operation of the light source during derivatization, the temperature inside the derivatization pipeline rises, affecting the derivatization pipeline and the derivatization effect. Particulate impurities and other substances that enter the internal system during the air exchange process between the inside and outside of the derivatization instrument exist between the light source and the derivatization pipeline, and even adhere to the surfaces of the light source and the derivatization pipeline, greatly attenuating the energy transmitted from the ultraviolet light source into the derivatization pipeline and affecting the derivatization effect. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that when the derivatization pipeline has problems and needs to be replaced, the pipeline needs to be removed and then rewound, thus wasting labor, and when the derivatization pipeline leaks liquid, the derivatization effect will fail and cannot be monitored in time.

[0005] To solve the above technical problems, the present utility model provides a dual-wavelength light source derivatizer with a derivatization pipeline that can be quickly replaced, including a housing.

A support seat is provided near the second partition in the heat dissipation room, and a heat dissipation fan is embedded in the housing rear plate.

The power socket is electrically connected to the control module and the heat dissipation fan respectively, and the ultraviolet light source device is electrically connected to the support seat and the control module in sequence.

[0030] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the attached drawings in the embodiments of the present utility model.

[0031] Combined with the attached Figure 1-7 As shown, a dual-wavelength light source derivative instrument capable of quickly replacing a derivative pipeline includes a housing, the housing includes an outer shell bottom plate 101, an outer shell front plate 102, an outer shell top plate 103, and an outer shell rear plate 104. A first partition 9 is provided between the outer shell front plate 102 and the outer shell rear plate 104, and a second partition 10 is vertically provided on the first partition 9. The housing and the first partition 9 and the second partition 10 form a control room 13, an equipment room 14, and a heat dissipation room 15.

[0032] The control room 13 is equipped with a control module 2 and a power socket 7. The control module 2 is embedded on the outer shell front plate 102, and the power socket 7 is embedded on the outer shell rear plate 104.

[0033] By setting the control module 2 to select a timed shutdown time, which can be accurate to minutes, accurate time control can be achieved to avoid wasting the life of the ultraviolet light source and electricity consumption.

[0034] The control module 2 controls the derivative instrument to be able to shut down regularly through a built-in delay time relay control module.

[0035] The control module 2 is a formed accessory that can be purchased on the market.

[0036] A support seat 5 is provided near the second partition 10 in the heat dissipation chamber 15. A heat dissipation fan 11 is embedded in the rear plate 104 of the outer shell. One end of the support seat 5 is installed with an ultraviolet light source device 4, and the other end passes through the second partition 10 and extends to the equipment chamber 14. A derivative pipeline assembly module 3 is provided below the ultraviolet light source device 4. The light source of the ultraviolet light source device 4 has at least two.

[0037] The heat dissipation fan 11 dissipates heat from the equipment in the shell, improving the stability of the equipment.

[0038] The power socket 7 is electrically connected to the control module 2 and the heat dissipation fan 11 respectively. The ultraviolet light source device 4 is sequentially electrically connected to the support seat 5 and the control module 2. A copper sheet 16 is arranged in the support seat 5. The support seat 5 is electrically connected to the ultraviolet light source device 4 through the copper sheet 16. A power interface 17 is provided on one side of the support seat 5, and the power interface 17 is electrically connected to the control module.

[0039] The control module 2 and the heat dissipation fan 11 are powered by the power socket 7, and the control module 2 transmits signals to the ultraviolet light source device 4 through the support seat 5.

[0040] It is convenient for the disassembly and replacement of the ultraviolet light source device 4.

[0041] The derivative pipeline assembly module 3 includes a bottom support plate 301. A lens metal plate 302, a derivative pipeline 303, and an upper cover plate 304 are sequentially stacked on the bottom support plate 301. The bottom support plate 301, the lens metal plate 302, the derivative pipeline 303, and the upper cover plate 304 are connected by bolts.

[0042] The bottom support plate 301, the lens metal plate 302, the derivative pipeline 303, and the upper cover plate 304 form a derivative pipeline assembly body 3, which can be replaced as a whole.

[0043] Among them, the derivative pipeline 303 adopts a three-dimensional grid weaving structure, and the upper cover plate 304 adopts quartz glass or alumina sapphire with high ultraviolet light transmittance, which plays the role of pressing the upper surface of the derivative pipeline 303 evenly to receive ultraviolet light. Also, because of the use of high-ultraviolet-light-transmitting materials, it produces less attenuation of the ultraviolet light emitted by the ultraviolet light source 4.

[0044] The lens metal plate 302 can be made of mirror aluminum plate or mirror stainless steel plate, ensuring a high reflectivity of ultraviolet light.

[0045] The derivative pipeline assembly module 3 is an integral whole. When replacing, only need to open the front plate 102 of the outer shell, and then the whole can be replaced. There is a gap between the bottom support plate 301 and the bottom plate 101 of the outer shell, which is in the circulating air duct, and the heat can be better taken away by the heat dissipation fan 11.

[0046] On one side of the derivative pipeline assembly module 3, there is an ultraviolet detection module 12. Below the derivative pipeline assembly module 3, there is a liquid leakage detection module 8. The ultraviolet detection module 12 and the liquid leakage detection module 8 are respectively electrically connected to the control module 2.

[0047] The liquid leakage detection module 8 is located below the derivative pipeline assembly module 3. When there is a liquid leakage in the derivative pipeline 303, the liquid leakage can be immediately detected, reminding the personnel to replace the derivative pipeline assembly module 3 as soon as possible.

[0048] The radiation intensity of the ultraviolet light source detected by the ultraviolet detection module 12 can be directly monitored on the control module 2, and the service life of the ultraviolet light source can also be directly monitored on the control module 2.

[0049] The ultraviolet detection module 12 is implemented by a UV ultraviolet light intensity sensor plus a timer.

[0050] A number of ventilation holes of uneven sizes are provided on both the first partition plate 9 and the second partition plate 10. The ventilation holes on the first partition plate 9, the ventilation holes on the second partition plate 10, the control room 13, the equipment room 14, and the heat dissipation room 15 form an air duct. The air duct holes on the rear plate 104 of the housing form a cycle with the outside world, circulating the heat generated during the derivation process out.

[0051] The rear plate 104 of the housing is embedded with an air filter 6, and the air filter 6 extends into the control room 13.

[0052] The cooling fan 11 circulates the ambient air through the holes on the rear plate 104 of the housing and passes through the air filter 6, so that particulate matters and other impurities in the air are adsorbed on the air filter 6, preventing particulate matters and other impurities in the air from entering the internal enclosed space to absorb the energy of the ultraviolet light wave, thereby ensuring the derivation effect.

[0053] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
