Description

Technical Field

[0001] The present invention relates to the technical field of atomic absorption spectrometers, and specifically to an atomic absorption spectrometer for detecting new materials. Background Technique

[0002] An atomic absorption spectrometer is an analytical chemistry device used in laboratories to determine the content of specific metal elements in samples. Its core principle is based on the absorption phenomenon of ground-state atoms for light of a specific wavelength (usually ultraviolet or visible light). Atomic absorption spectrometers are divided into flame atomizers and graphite furnace atomizers. The sample solution is aspirated into the flame (such as an air-acetylene flame, a helium-acetylene flame), and the high temperature causes the solvent to evaporate, and the compounds in the sample dissociate (or decompose) into gaseous ground-state atoms. At the same time, the atomic absorption spectrometer cooperates with the light source lamp position box to achieve detection after absorption.

[0003] The utility model with the publication number CN209927712U discloses an atomic absorption spectrometer, which includes an atomic absorption spectrometer main body, a sampler fixed to the atomic absorption spectrometer main body, and also includes a lifting table installed at the bottom of the atomic absorption spectrometer main body and a water bottle placed on the lifting table. An installation groove for installing the lifting table is provided on the side wall of the atomic absorption spectrometer main body. The lifting table includes a base installed on the top surface of the installation groove and a lifting sleeve installed on the outside of the base. An internal thread is appropriately provided on the inner wall of the lifting sleeve, and an external thread matched with the internal thread is provided on the side wall of the base.

[0004] The utility model with the publication number CN207636481U discloses an atomic absorption spectrometer. By setting a driving servo motor, a rotating rod, a threaded rod, a driving gear, a driven gear, and a sliding plate, the driving servo motor can be adjusted to rotate forward and backward by starting the forward and reverse switch. The output end of the driving servo motor drives the rotation of the driving gear through a coupling. Since the driving gear meshes with the driven gear, the rotation of the two driven gears is driven, thereby driving the rotation of the rotating rod. Since the rotating rod is threadedly connected to the threaded rod, the threaded rod is driven to make a reciprocating motion, so the sliding plate is driven to rise or fall, and the universal wheel is driven to come out of the through hole to facilitate movement.

[0005] However, the above-disclosed atomic absorption spectrometers still have the following problems in actual use: During the operation of the atomic absorption spectrometer, the liquid extraction pipeline needs to be manually reciprocally switched between the standard liquid bottle and the solution reagent bottle, and the operator manually grabs and switches. On the one hand, it affects the accuracy of atomic measurement data, and on the other hand, if the standard liquid bottle is not replaced, it is easy to cause mutual contamination and mixing among various solution reagents.

[0006] Therefore, we propose an atomic absorption spectrometer for detecting new materials to solve the problems raised above. Summary of the Invention

[0007] The object of the present invention is to provide an atomic absorption spectrometer for detecting new materials. In the process of operating the existing atomic absorption spectrometer, it is necessary to manually reciprocally convert the liquid extraction pipeline between the standard liquid bottle and the solution reagent bottle, and the operator manually grabs and converts it.

[0014] Preferably, the absorption mechanism includes a limiting bracket, and the outer end of the limiting bracket is fixedly installed on the left and right sides of the top surface of the front end of the lifting strip, and the inner end of the limiting bracket slides through the left and right sides of the interior of the lifting threaded rod.

[0021] Further, the transmission gear disengaged from the incomplete gear is reset with the threaded sleeve through the torsion spring, and then drives the lifting threaded rod and the liquid extraction bellows connected by threads to descend synchronously, so that the liquid extraction bellows enters the adjacent actual solution bottle inside, so as to realize the repeated operations of calibration and detection during detection.

[0022] 4. The flame detector sucks the standard liquid in the standard liquid bottle corresponding to the bottom end of the liquid extraction bellows in the standard liquid storage hole for calibration. When the flame detector turns yellow and stabilizes, the solution reagent bottle inside the adjacent reagent storage hole is detected. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1 - 11 , the present invention provides the following technical solutions: Embodiment 1: To solve the problems existing in the use and operation of existing atomic absorption spectrometers, therefore, the following technical solutions are disclosed in this embodiment. An atomic absorption spectrometer for new material detection includes a spectrometer main body 1 and a lamp - position box body 2 fixedly installed on the right side of the spectrometer main body 1; a flame detector 3 is fixedly installed at the top inside the spectrometer main body 1, and a visual protection plate 4 is hinged to the front of the flame detector 3, and gas is transported through a gas - supply pipeline 5 on the left side of the flame detector 3.

[0027] A liquid supply mechanism is arranged below the front surface of the spectrometer body 1, and the liquid supply mechanism includes a liquid supply supporting platform 6, and a liquid supply rotating disk 7 is arranged inside the liquid supply supporting platform 6 by being rotated by a motor; the rear end of the liquid supply supporting platform 6 included in the liquid supply mechanism is rotatably arranged below the front surface of the spectrometer body 1 by a bearing, and reagent storage holes 10 and standard liquid storage holes 11 are arranged inside the liquid supply rotating disk 7 at equal angles, and the reagent storage holes 10 and the standard liquid storage holes 11 are distributed in a staggered manner at equal angles.

[0028] like Figures 1 - 2 As shown, when operating the spectrometer body 1, ensure that the lamp position box 2 on the right side is in working condition, and at the same time connect the gas supply pipe 5 on the left side of the flame detector 3 to the gas cylinder, and then open the visual protection plate 4 on the front of the flame detector 3, ignite the flame detector 3, lower the visual protection plate 4, and determine the status by observing the color of the flame.

[0029] Furthermore, the liquid supply supporting platform 6 on the front side of the spectrometer body 1 is manually rotated downward to drive the liquid supply rotating disk 7 that is internally rotated to rotate to a horizontal state, and then the standard liquid bottles and solution reagent bottles to be tested are placed in a staggered manner in the reagent storage holes 10 and the standard liquid storage holes 11 opened inside the liquid supply rotating disk 7, so that in the subsequent detection process, staggered operation of calibration and absorption can be realized to avoid mixing and contamination between different solutions.

[0030] Embodiment 2: In order to solve the problems existing in the operation of the existing atomic absorption spectrometer, the present embodiment discloses the following technical scheme: the absorption mechanism includes a guide slide bar 14, and the guide slide bar 14 is fixedly installed on the left and right sides of the lower part of the inside of the spectrometer body 1, and the guide slide bar 14 slides through the bottom end of the liquid collection slide bar 8, and the liquid collection slide bar 8 and the guide slide bar 14 are connected to each other through a reset spring 15, and the liquid collection slide bar 8 slides in contact with the inner wall of the spectrometer body 1; the absorption mechanism includes a lifting strip 16, and the lifting strip 16 is slidably installed at the center position of the liquid collection slide bar 8, and the left and right sides of the lifting strip 16 slide through the inner end of the positioning bracket 17, and the outer ends of the symmetrically arranged positioning bracket 17 are fixedly installed on the left and right sides of the top surface of the liquid collection slide bar 8.

[0031] The absorption mechanism includes a resisting inclined block 24, and the resisting inclined block 24 is fixedly installed at the rear of the spectrometer body 1, and the top surface of the resisting inclined block 24 is connected to the rear end bottom surface of the lifting strip 16, and the contacting inclined block 24 and the lifting strip 16 are arranged in an inclined structure at the joint. The lifting strip 16 slides backward and is squeezed by the resisting inclined block 24, so that the lifting strip 16 drives the liquid collection bellows 9 to rise for storage.

[0032] The liquid absorption mechanism includes a traction cable 25. The top end of the traction cable 25 is fixedly connected to the left and right sides of the bottom surface of the liquid extraction slide plate 8. Moreover, the bottom end of the traction cable 25 is fixedly connected to the left and right sides of the top surface of the liquid supply carrier 6 near the spectrometer body 1, so that when the liquid supply carrier 6 rotates and opens, it drives the liquid supply carrier 6 to slide forward to realize the detection operation.

[0033] As Figures 10 - 11 shown, during the process of the liquid supply carrier 6 in front of the spectrometer body 1 rotating downward for use, the traction cable 25 fixedly connected to its top surface moves along with it and becomes taut, so that the traction cable 25 drives the liquid extraction slide plate 8 fixedly connected to the rear end to slide forward synchronously with the lifting strip plate 16. At the same time, during the movement of the lifting strip plate 16, it always fits with the top surface of the abutting inclined block 24. Furthermore, the inclined surface structure of the abutting inclined block 24 drives the lifting strip plate 16 to continuously slide downward, and the positioning bracket 17 limits the descending lifting strip plate 16 and the liquid extraction bellows 9. When the liquid extraction slide plate 8 slides forward in place, the lifting strip plate 16 drives the liquid extraction bellows 9 to make its bottom end enter the corresponding reagent storage hole 10 or standard liquid storage hole 11, so as to prevent the liquid extraction bellows 9 from being contaminated and affecting the detection accuracy.

[0034] Embodiment 3: In order to solve the problems existing in the use and operation of the existing atomic absorption spectrometer, the following technical solutions are disclosed in this embodiment. Among them, a liquid absorption mechanism is provided below the interior of the spectrometer body 1. The liquid absorption mechanism includes a liquid extraction slide plate 8, and a liquid extraction bellows 9 is disposed through the middle of the front end of the liquid extraction slide plate 8. Moreover, the top end of the liquid extraction bellows 9 is connected in communication with the flame detector 3; the liquid supply mechanism includes a guiding tooth block 12, and the guiding tooth block 12 is fixedly installed at equal angles on the outer wall of the upper end of the liquid supply rotating disk 7. A guiding gear 13 is disposed in the middle of the rear of the liquid supply rotating disk 7, and the guiding gear 13 is meshed with the guiding tooth block 12. Moreover, the guiding gear 13 is slidably disposed at the rear of the top surface of the liquid supply carrier 6.

[0035] The absorption mechanism includes a threaded sleeve 18, and the threaded sleeve 18 is rotatably arranged at the front end inside the lifting strip plate 16 through a torsion spring. The inside of the threaded sleeve 18 is threadedly connected to the upper end of the lifting threaded rod 19, and the inside of the lifting threaded rod 19 is slidably connected to the upper front of the liquid extraction bellows 9. The absorption mechanism includes a limit bracket 20, and the outer ends of the limit brackets 20 are fixedly installed on the left and right sides of the top surface at the front end of the lifting strip plate 16, and the inner ends of the limit brackets 20 slidably penetrate through the left and right sides inside the lifting threaded rod 19. The limit bracket 20 limits the lifting threaded rod 19, so that when it lifts and lowers, it drives the bottom end of the liquid extraction bellows 9 to lift and lower in the reagent bottle and the standard liquid bottle to achieve conversion. The absorption mechanism includes a transmission gear 21, and the transmission gear 21 is fixedly installed at the bottom end of the threaded sleeve 18 on the bottom surface of the lifting strip plate 16. A non-complete gear 22 is meshed and connected behind the transmission gear 21, and the non-complete gear 22 is fixedly connected to the upper end of the transmission rotating shaft 23. At the same time, the bottom end of the transmission rotating shaft 23 is fixedly connected to the guiding gear 13, and the top end of the transmission rotating shaft 23 is rotatably arranged on the bottom surface of the lifting strip plate 16 through a bearing.

[0036] As Figures 4 - 6 shown, during the process of the lifting strip plate 16 moving forward, it drives the transmission rotating shaft 23 and the guiding gear 13 on the bottom surface to slide synchronously, so that the guiding gear 13 is meshed and connected to the guiding tooth block 12 on the outer wall of the liquid supply rotating disk 7. Then, during the measurement process, the flame detector 3 sucks the standard liquid bottle in the standard liquid storage hole 11 corresponding to the bottom end of the liquid extraction bellows 9 for calibration. When the flame detector 3 turns yellow and stabilizes, it detects the solution reagent bottle inside the adjacent reagent storage hole 10.

[0037] As Figures 7 - 9 shown, the motor inside the liquid supply carrier 6 drives the liquid supply rotating disk 7 to rotate. The guiding tooth block 12 on its outer part drives the meshed and connected guiding gear 13 and the transmission rotating shaft 23 to rotate. During the process of the non-complete gear 22 at the top end of the transmission rotating shaft 23 being meshed with the transmission gear 21, the transmission gear 21 drives the threaded connection between the threaded sleeve 18 and the lifting threaded rod 19. After the lifting threaded rod 19 is limited by the limit bracket 20, it drives the liquid extraction bellows 9 inside it to move upward, and then separates from the standard liquid bottle to avoid affecting the conversion of the liquid supply rotating disk 7.

[0038] Furthermore, when the non-complete gear 22 disengages from the transmission gear 21, the threaded sleeve 18 connected by the torsion spring rotates back to its original position, so that the internal lifting threaded rod 19 drives the liquid extraction bellows 9 to slide downward, and then the liquid extraction bellows 9 is inserted into the solution reagent bottle in the reagent storage hole 10 of the liquid supply rotating disk 7 after rotation for the detection of solution atoms. By rotating back and forth, the liquid extraction bellows 9 is cyclically converted between the standard liquid bottle and the solution reagent bottle to improve the accuracy of the atomic detection data.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
