Description

Technical Field

[0001] The utility model relates to the technical field of flame photometer atomization, in particular to an atomizer for a flame photometer. Background Art

[0002] A flame photometer is an analytical instrument based on emission spectroscopy. It uses a flame as an excitation light source and employs a photoelectric detection system to measure the intensity of radiation emitted when an excited element returns to its ground state. The nebulizer, which atomizes the test liquid for detection, is a crucial component of a flame photometer. The nebulizer's atomization performance significantly impacts measurement precision and chemical interference. Therefore, the nebulizer must provide stable spray, small, uniform droplets, and high atomization efficiency. Appropriate nebulizer structure and needle diameter can effectively ensure uniform droplet size, improve atomization efficiency, and enhance test sensitivity and precision.

[0003] China's authorized announcement number is CN 217717461 U, a flame photometer atomizer. The atomizer outlet of this flame photometer atomizer is inserted into the connecting pipe, completing the initial positioning between the atomizer body and the atomizer chamber. The corresponding air intake pipe is connected to the inside of each connected pipe. The air intake pipe not only seals the connected pipes, but also further positions the atomizer body and the atomizer chamber, so that the atomizer body and the atomizer chamber can be stably connected, allowing liquid to be quickly discharged from the liquid outlet pipe, avoiding liquid accumulation in the atomizer body and interfering with the measurement sensitivity and accuracy. This atomizer has a simple structure, is easy to operate, easy to disassemble and install, has good sealing performance, can quickly discharge accumulated liquid, and effectively improves the accuracy of measurement.

[0004] However, this patent still has certain shortcomings when used. Before the sample liquid to be tested enters the nebulizer, the sample liquid is generally an untreated solution. The untreated solution may contain a large amount of impurities. Directly entering the nebulizer may cause damage to the nebulizer, thereby causing resource loss. If blockage occurs due to impurities, the operator needs to first stop the device and then clear the impurities. The clearing process will affect the progress of subsequent detection, thereby causing the operator to reduce the detection rate. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1.

The connection between the fixing component and the liquid inlet makes the installation and disassembly process simpler and convenient for the operator. When the liquid inlet needs to be exposed, the pressing blocks on both sides of the mounting piece are pressed to the middle position, so that the moving block slides along the moving groove, and the moving block drives the gear plate to rotate. At the same time, the gear plate drives the card block to retract backward, so that the card block and the mounting grooves on both sides of the liquid inlet are separated, thereby realizing disassembly. When installation is required, it is only necessary to press the pressing block first to complete the splicing of the liquid inlet and the mounting piece, and then release the pressing block. Under the action of the spring rebound, the card block moves and is engaged with the mounting groove on the side of the liquid inlet to realize installation. When the card block moves, it drives the gear plate to rotate, thereby driving the pressing block to move and reset, so as to facilitate the next operation. The disassembly process is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, Figure 2 、 Figure 3 and Figure 5As shown, the filter assembly 8 includes a filter cartridge 801 fixedly connected to the side of the photometer body 1 through a fixing rod 9, the inner bottom wall of the filter cartridge 801 is a slope with an inclination angle of 30 degrees, and a liquid inlet pipe 802 is provided at the bottom of the filter cartridge 801, and a filter screen 806 is fixedly connected to the inside of the filter cartridge 801, and a gear ring 805 is rotatably connected to the inside of the filter cartridge 801.

A power chamber 803 is provided on the side of the filter cartridge 801, and a rotating rod 809 is rotatably connected to the inside of the power chamber 803. One end of the rotating rod 809 is fixedly connected to the fan impeller 810, and the other end of the rotating rod 809 is fixedly connected to a bevel gear 808. The bevel gear 808 and the gear ring 805 are vertically meshed. The top of the filter cartridge 801 is fixedly connected to the top of the power chamber 803 through a third connecting pipe 804.

[0028] Among them, by setting up the filter assembly 8, the sample liquid is pre-treated, so that the impurities in the sample liquid entering the nebulizer body 2 are reduced, which can effectively reduce the reduction in detection efficiency caused by the blockage of the nebulizer body 2. The switch of the delivery pump 6 is turned on. Under the action of the delivery pump 6, the sample liquid begins to be sucked from the liquid inlet pipe 802. The sample liquid filters the filter screen 806 upward until it fills the entire filter cartridge 801. Then, it enters the power chamber 803 from the third connecting pipe 804. Under the action of the sample liquid flow, the fan impeller 810 starts to rotate, and the fan impeller 810 drives the rotating rod 809 to make the bevel gear 80 8 rotates. Since the bevel gear 808 and the gear ring 805 are meshed and connected, the gear ring 805 is driven to rotate. During the rotation of the gear ring 805, the scraper 807 on the top of the gear ring 805 scrapes the bottom of the filter 806 to prevent clogging during the filtration process. After that, the sample liquid in the power chamber 803 is extracted by the delivery pump 6 and delivered through the second connecting pipe 7 and the first connecting pipe 5 into the nebulizer body 2 for atomization operation. Self-cleaning of the filter 806 is achieved during the filtration process. Compared with traditional filtering devices, the time for dismantling and cleaning is reduced, and the working efficiency is improved.

[0029] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the fixing component 4 includes a mounting part 401 fixedly connected to the first connecting tube 5, a flow groove 402 is provided at the center of the mounting part 401, a moving groove 403 and a retraction groove 410 are respectively provided inside the mounting part 401, a moving block 404 is slidably connected inside the moving groove 403, a pressing block 405 is fixedly connected to the side of the moving block 404, a clamping block 407 is slidably connected inside the retraction groove 410, a spring 409 is provided on the side of the clamping block 407, one end of the spring 409 is elastically connected to the inner wall of the retraction groove 410, the other side of the spring 409 is elastically connected to the clamping block 407, a damping rod 408 is provided inside the spring 409, the interior of the mounting part 401 is rotatably connected to a gear plate 406, the outside of the gear plate 406 is meshed with the bottom of the moving block 404, and the outside of the gear plate 406 is meshed with the top of the clamping block 407.

[0030] Among them, by setting up the fixing component 4, the filter device and the atomizer body 2 are quickly installed. When the atomizer body 2 needs to be maintained, the liquid inlet 3 needs to be exposed, and the inside of the atomizer body 2 is cleaned through the liquid inlet 3. The connection between the fixing component 4 and the liquid inlet 3 makes the installation and disassembly process simpler and more convenient for the operator. When the liquid inlet 3 needs to be exposed, the pressing blocks 405 on both sides of the mounting member 401 are pressed to the middle position, so that the moving block 404 slides along the moving groove 403, and the moving block 404 drives the gear plate 406 to rotate. , the gear plate 406 drives the card block 407 to retract backward, thereby separating the card block 407 from the mounting grooves on both sides of the liquid inlet 3, thereby realizing disassembly. When installation is required, only the pressing block 405 is needed to complete the splicing of the liquid inlet 3 and the mounting piece 401, and then the pressing block 405 is released. Under the action of the spring 409 rebounding, the card block 407 moves and engages with the mounting groove on the side of the liquid inlet 3 to realize installation. When the card block 407 moves, it drives the gear plate 406 to rotate, thereby driving the pressing block 405 to move and reset to facilitate the next operation. The disassembly and assembly process is simple and easy to operate.

[0031] The working process of the present invention is as follows: when the flame photometer atomizer designed by the present invention is in operation, when it is necessary to filter the sample liquid, the switch of the delivery pump 6 is first turned on. Under the action of the delivery pump 6, the sample liquid begins to be sucked in from the liquid inlet pipe 802, and the sample liquid filters the filter screen 806 upward until the entire filter cartridge 801 is filled. Then, it enters the power chamber 803 from the third connecting pipe 804. Under the action of the sample liquid flow, the fan impeller 810 starts to rotate, and the fan impeller 810 drives the rotating rod 809 to rotate the bevel gear 808. Since the bevel gear 808 and the gear ring 805 are meshed and connected, the gear ring 805 is driven to rotate. During the rotation of the gear ring 805, the scraper 807 on the top of the gear ring 805 scrapes the bottom of the filter screen 806 to prevent blockage during the filtration process. After that, the sample liquid in the power chamber 803 is extracted by the delivery pump 6 and transported through the second connecting pipe 7 and the first connecting pipe 5 into the nebulizer body 2 for atomization. The filter screen 806 is self-cleaned during the filtration process. Compared with the traditional filtering device, the time for disassembly and cleaning is reduced, and the working efficiency is improved. When the liquid inlet 3 needs to be exposed, the pressing blocks 405 on both sides of the mounting member 401 are pressed to the middle position, so that the moving block 404 slides along the moving groove 403, and the moving block 404 drives the gear plate 406 to rotate. At the same time, the gear plate 406 drives the clamping block 407 to retract backward, so that the clamping block 407 and the mounting grooves on both sides of the liquid inlet 3 are separated, thereby realizing disassembly. When installation is required, only the pressing block 405 needs to be pressed first to complete the splicing of the liquid inlet 3 and the mounting member 401, and then the pressing block 405 is released. Under the action of the rebound of the spring 409, the clamping block 407 moves and engages with the mounting groove on the side of the liquid inlet 3 to realize installation. When the clamping block 407 moves, it drives the gear plate 406 to rotate, thereby driving the pressing block 405 to move and reset, so as to facilitate the next operation.
