Description

Technical Field

[0001] The utility model relates to the technical application field of mercury lamp equipment, in particular to a mercury lamp device used for debugging the optical path of atomic emission spectrum. Background Art

[0002] In the process of debugging the atomic emission spectrometry optical path, a mercury lamp with a power of 1000W is required as a light source. However, the mercury lamp will generate a lot of heat and strong ultraviolet rays when working. The ultraviolet rays are harmful to the human body and need to be shielded, and the heat needs to be dissipated in time. In order to solve this problem, some solutions have been proposed in the prior art. As mentioned in the publication number CN214175972U, the high-performance mercury lamp prolongs the service life of the mercury lamp by means of a protective cover and a fan to dissipate heat, but it cannot effectively shield the ultraviolet light emitted by the mercury lamp. The mercury lamp tooling with water cooling and heat dissipation places the mercury lamp completely in the coolant. Although it can effectively shield the ultraviolet light emitted by the mercury lamp, the equipment is bulky and the use process is complicated, which increases the time cost of personnel.

[0003] The existing technology has some problems or shortcomings in the heat dissipation and light shielding of mercury lamps. First, although the solutions in the existing technology can effectively dissipate heat, they cannot take into account the light shielding effect, which poses a potential hazard to the health of the commissioning personnel; or although they can take into account both heat dissipation and light shielding, the equipment is bulky and inconvenient to use. Therefore, a new technical solution is needed to solve the heat dissipation and light shielding problems of mercury lamps and improve the work efficiency of commissioning personnel. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a mercury lamp device for debugging the optical path of atomic emission spectroscopy. The device uses a condenser, heat dissipation fins, a fan and a turbine vent to cooperate with each other to solve the technical problems of mercury lamp heat dissipation and shading, thereby preventing ultraviolet light from causing harm to personnel.

[0005] The technical solution of the utility model is: a mercury lamp device for debugging the light path of atomic emission spectroscopy, comprising a light source component and a mounting component used in conjunction with the light source component;

[0007] Furthermore, the condenser includes an arc-shaped plate and two side plates, the two side plates are respectively fixed to opposite sides of the arc-shaped plate, the mercury lamp passes through the two side plates, and the heat dissipation fins are fixed to the outer side wall of the arc-shaped plate.

[0008] Furthermore, the side plate is provided with a spring clip, and the spring clip fixes the mercury lamp and the condenser.

[0009] Furthermore, the side plate is also connected to a fixing bracket, and the condenser is fixed in the aluminum box through the fixing bracket.

[0012] Furthermore, the rotation directions of the two fans are opposite, and the airflow directions of the two turbine vents are opposite.

[0013] Furthermore, the bottom of the aluminum box is provided with feet.

[0014] The beneficial technical effects of the utility model are:

[0030] like Figure 1-Figure 5 As shown, the utility model specifically relates to a tooling device for heat dissipation and light shielding of a mercury lamp 210, including a light source assembly 200 and a mounting assembly 100 used in conjunction with the light source assembly 200;

[0031] The light source assembly 200 includes an aluminum box 260 and a mercury lamp 210 disposed in the aluminum box 260 through a condenser 230, and a plurality of heat dissipation fins 240 are disposed on the outer side of the condenser 230; a light-transmitting opening 261 is disposed on the upper end surface of the aluminum box 260, and the mounting assembly 100 is provided with a shape structure for use with the light-transmitting opening 261.

[0032] It should be noted that the installation assembly 100 facilitates the installation of the mercury lamp 210 onto the optical chamber of the direct-reading spectrometer for debugging, and the light source assembly 200 provides ultraviolet light for the debugging process.

[0033] Select a mercury lamp 210 with a power of 1000W, an operating temperature of 800°C, a light emission wavelength of 365nm, and a radiation intensity of 10μW / cm 2 A condenser 230 is installed on the mercury lamp 210 so as to concentrate the light of the mercury lamp 210 and improve the light source intensity.

[0034] Aluminum heat sink fins 240 are provided on the outside of the condenser 230 to absorb the heat of the condenser 230 and increase the heat dissipation surface area. In this embodiment, the number of fins is 12, the length is 14CM, and the thickness is 1mm.

[0035] The mercury lamp 210, the condenser 230 and the heat sink fins 240 are encapsulated in an aluminum box 260, which can prevent the ultraviolet rays generated by the mercury lamp 210 from causing harm to the surrounding environment and human body. A light-transmitting opening 261 is left above the box, through which the light required for work can be transmitted.

[0036] The condenser 230 includes an arc-shaped plate and two side plates, the two side plates are respectively fixed to opposite sides of the arc-shaped plate, the mercury lamp 210 passes through the two side plates, and the heat dissipation fins 240 are fixed to the outer side wall of the arc-shaped plate.

[0037] The side plate is provided with a spring clip 220 , and the spring clip 220 fixes the mercury lamp 210 and the focusing cover 230 .

[0038] The condenser 230 is made of aluminum, the mercury lamp 210 is fixed by a spring clip 220, and the inner surface of the arc plate and the inner surface of the two side plates are polished to concentrate the light of the mercury lamp 210 and improve the light source intensity.

[0039] The side plate is further connected to a fixing bracket 250 , and the condenser 230 is fixed in the aluminum box 260 through the fixing bracket 250 .

[0040] The function of the fixed bracket 250 is not only to support the condenser 230 so that the condenser 230 is in a suspended state, ensuring that the heat dissipation fins 240 will not interfere with the bottom of the aluminum box 260, but also to shorten the distance between the condenser 230 and the light-transmitting port 261 of the aluminum box 260, ensuring that the light of the mercury lamp 210 is concentrated and not emitted.

[0041] The aluminum box 260 is further provided with air vents 262 on opposite sides thereof. A fan 270 is provided at the air vents 262 and connected to the turbine vents 280 through the fan 270 .

[0046] Furthermore, the turbine vent 280 is entirely sprayed with black paint, which can absorb light better and further prevent light from escaping.

[0047] The bottom of the aluminum box 260 is provided with a foot 300 .
