Description

Technical Field

[0001] The present application relates to the technical field of chemical composition analysis equipment, and in particular to a chemical composition analysis device and method. Background Art

[0002] Chemical composition analysis is a method of qualitative and quantitative analysis of the chemical composition in a material sample. This is one of the most basic and common experiments in a chemical laboratory, used to confirm the properties of a substance, detect the content and purity of a component, and can serve as a basis for further research. Composition analysis is mainly an analysis of unknown substances and unknown components. By using a variety of separation and analysis methods, each component in the sample is qualitatively and quantitatively analyzed to determine the structure of the component and fully understand the sample.

[0003] Among them, the chemical composition analysis device can analyze the chemical composition in the sample, such as a polymer chemical composition analysis device with publication number CN214472142U, which includes a box body, an upper hopper is arranged on the upper side of the box body, and the middle part of the upper hopper is rotatably connected with a first crushing roller and a second crushing roller in sequence, a driving gear is arranged on the front side of the first crushing roller, and a driven gear meshing with the driving gear is arranged on the front side of the second crushing roller, and a first motor is connected to the front side of the driving gear, and an arc-shaped elbow is connected to the lower side of the upper hopper, and a cutting cavity is arranged at the left end of the arc-shaped elbow, and a rotating rod is arranged inside the cutting cavity, and a plurality of blades are arranged in the middle of the rotating rod, and a second motor is connected to the left end of the rotating rod, and a filter screen is arranged on the lower side of the cutting cavity, and the filter screen is connected to a feed pipe, and a decomposition chamber is connected to the lower side of the feed pipe, and a stirring component is arranged in the middle of the decomposition chamber; the above-mentioned prior art has the advantages of simple structure, safety and practicality, convenient operation, good crushing effect and more sufficient stirring.

[0004] However, the above-mentioned prior art still has some defects in chemical composition analysis: 1. After the above-mentioned prior art crushes the chemical material into small pieces, it enters the cutting chamber and is cut by a blade, thereby achieving a better crushing effect on the chemical material and accelerating its decomposition in the decomposition chamber. However, in actual use, the chemical material may not be completely decomposed due to its own insufficient purity or other reasons. At this time, the residue of the chemical material remains in the decomposition chamber and is difficult to remove.

[0005] 2. The above-mentioned prior art is to set up a circulation pump and then perform stirring and decomposition through a stirring component, so that the stirring component can stir more fully and thoroughly, and the decomposition liquid can be decomposed faster. However, in order to analyze the substances in the decomposition liquid, it is necessary to start the solenoid valve on the right side of the discharge pipe and close the solenoid valve in the middle of the circulation pipe to take out the liquid. Various chemical substances are mixed in the decomposition liquid, which requires subsequent processing, and the output substances in the decomposition liquid cannot be directly observed.

When the reaction is completed, the first connecting rod 161 is slid to the lower end of the first connecting hole 15, that is, the rotating disk 42 slides to the lower end of the connecting sliding hole 43. During the sliding process, under the action of the connecting spring 55, the telescopic tube 53 extends, and the water-blocking plate 54 keeps the water hole 51 closed. When the rotating disk 42 slides to the bottom of the connecting sliding hole 43, the telescopic tube 53 extends to the maximum limit, and the water-blocking plate 54 moves downward with the telescopic tube 53 to open the water hole 51.

[0054] refer to Figure 8 , is a schematic diagram of the structure of the centrifugal device 6 of the present invention. In order to detect the reaction liquid introduced into the detection cylinder 12 in layers, the detection cylinder 12 is provided with a centrifugal device 6. The centrifugal device 6 includes a driving motor 61 installed inside the detection cylinder 12. The output shaft of the driving motor 61 is connected with a rotating column 62, and the rotating column 62 is connected to the lower end of the rotating cylinder 361. The driving motor 61 drives the rotating column 62 and the rotating cylinder 361 to rotate. A centrifugal table 63 is also installed on the rotating column 62, and the center of the centrifugal table 63 is tilted downward to facilitate the separation of reaction products of different masses in the reaction liquid after the reaction. A plurality of detection holes 64 are evenly arranged on the upper end of the centrifugal table 63 in the circumferential direction. A detection tube 65 is installed in the detection hole 64, and the upper end opening of the detection tube 65 corresponds to the lower end of the connecting tube 46. The reaction liquid after the reaction enters the detection tube 65 through the connecting tube 46. The lower end of the connecting tube 46 is also provided with a sealing block 66 corresponding to the opening of the detection tube 65 to prevent the reaction liquid from splashing out of the detection tube 65.

[0055] After the rotating disk 42 is slid downward to the lower end of the connecting slide hole 43, the sealing cover 41 covers the detection tube 12. At the same time, the reaction liquid enters the detection tube 65 through the connecting tube 46, and the sealing block 66 closes the tube mouth of the detection tube 65. At this time, the driving motor 61 is started to rotate the centrifuge table 63 to perform differential centrifugation on the reaction liquid in the detection tube 65, so as to facilitate the detection of substances in the reaction liquid to analyze the chemical composition of the sample.

[0056] refer to Fig. 9 and Fig.10In order to control the position of the sliding column 16 in the sliding cylinder 14, a control device 7 is provided at the lower end of the sliding column 16. The control device 7 includes a control handle 71 provided at the end of the second connecting rod 162 away from the sealing cover 41. The sliding column 16 is moved downward by pressing the control handle 71. A return spring 72 is connected between the lower end of the sliding column 16 and the sliding cylinder 14. The return spring 72 causes the sliding column 16 to slide upward, thereby causing the first connecting rod 161 and the second connecting rod 162 to be located at the upper ends of the first sliding hole 131 and the second sliding hole 132, respectively.

[0057] After the sliding column 16 is moved downward by pressing the control handle 71, in order to keep the first connecting rod 161 and the second connecting rod 162 respectively at the lower ends of the first sliding hole 131 and the second sliding hole 132, and then close the pulverizing frame 22 and the detection cylinder 12 with the closing plate 23 and the sealing cover 41, the control device 7 also includes a locking mechanism 73 arranged on the side wall of the lower end of the sliding cylinder 14, and the locking mechanism 73 includes a mounting frame 731 symmetrically arranged on the side wall of the lower end of the sliding cylinder 14, and a locking block 732 is slidably arranged in the mounting frame 731, and a sliding groove 733 is opened at the lower end of the sliding column 16, and the locking block 732 is located in the sliding groove 733 and slides, and a limiting block 734 is arranged in the middle of the sliding groove 733. When the locking cam 732 is in the state of being moved along the cam 736, the locking cam 736 will move upwards to lock the locking cam 736, so that the locking cam 736 can be turned off when the locking cam 736 is turned on.

[0058] After the sliding column 16 slides downward, under the action of the locking spring 736, the locking block 732 locks the limit block 734 to prevent the sliding column 16 from moving upward under the action of the return spring 72. When the sliding column 16 needs to be slid upward, the two return handles 737 are lifted at the same time to compress the locking spring 736, so that the limit block 734 is free from the restriction of the locking block 732. At this time, the sliding column 16 moves upward under the action of the return spring 72.

[0059] In addition, the present invention also provides a chemical composition analysis method, which comprises the following steps:

[0060] S1: Place the sample in the crushing frame 22, and then press the control handle 71 to slide the sliding column 16 downward until the blocking block 732 blocks the limiting block 734 to prevent the sliding column 16 from moving upward under the action of the return spring 72. At this time, the closing plate 23 covers the upper opening of the crushing frame 22 to prevent the sample from flying out of the crushing frame 22 when the sample is crushed, and at the same time reduce the interference of the external environment on the sample crushing. Then start the transmission motor 28 to drive the two rotating columns 62 to rotate, and the crushing teeth 26 crush the sample to be tested;

[0061] S2: The crushed sample falls into the filter cylinder 363 through the connecting hose 366. At this time, the reset handle 737 is pulled up, and the sliding column 16 slides upward under the action of the reset spring 72, and the closing plate 23 is opened to observe the crushing of the sample. After the sample is crushed, a proper amount of reaction liquid is added to the liquid adding cylinder 351, and the reaction liquid is introduced into the mixing cylinder 32 by rotating the rotating handle 355. At this time, the water-blocking plate 54 closes the water hole 51 under the action of the connecting spring 55 to prevent the reaction liquid from entering the telescopic tube 44 from the water hole 51;

[0062] S3: Start the driving motor 61 to drive the rotating cylinder 361 to rotate. At this time, the stirring paddle 368 stirs the reaction liquid to accelerate the reaction between the reaction liquid and the sample. When the reaction is completed, turn off the driving motor 61, disassemble the connecting ring 367 from the upper end of the filter cylinder 363, take out the filter cylinder 363, and recover the sample that has not been completely reacted from the filter cylinder 363. Press the control handle 71 again to move the sliding column 16 downward, and the water-blocking plate 54 moves downward under the drive of the telescopic cylinder 53, so that the reaction liquid after the reaction flows out from the water-through hole 51.

[0063] S4: The reaction liquid after the reaction enters the detection tube 65 through the telescopic tube 44 and the connecting tube 46 in turn, and then the driving motor 61 is started again to rotate the centrifugal table 63. At the same time, the sealing block 66 seals the mouth of the detection tube 65 to prevent the reaction liquid from overflowing. After the reaction liquid in the detection tube 65 is stratified, the driving motor 61 is turned off, the reset handle 737 is lifted, and the sealing cover 41 is opened. The chemical composition in the sample can be intuitively analyzed through the stratified detection tube 65.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
