[0002] Sodium glucoheptonate can be used to prepare acid-base indicators. It can also be used as a raw material for coordination reagents, complexing agents and dyes. During the processing, high-purity glucose needs to be dissolved in water and then sodium hydroxide is slowly added to dissolve and stir. At this time, the temperature is heated to about 80 degrees, and then it will react to generate a solution containing sodium glucoheptonate and some insoluble impurities.

[0029] In the present invention, in the sodium glucoheptonate content detection and extraction device and detection method, when the extraction detection dish slides along the first inclined plane and finally leaves the first inclined plane and slides onto the surface of the electric conveyor belt, it should be noted that the electric conveyor belt is in operation at the beginning, so the electric conveyor belt can transport the extraction detection dish after sampling to the specified position, and as the first turntable continues to rotate, the eighth horizontal axis will gradually resist and climb along the second inclined plane opened on the outer wall of the first turntable. During the climbing process, the eighth horizontal axis is resisted and carries the slider along the guide rod to press the reset spring down, so as to adapt to the slope of the second inclined plane, thereby realizing automatic unloading of the extraction detection dish and increasing the efficiency of batch sampling.

[0060] The outer wall of the detection and extraction table 1 is provided with an electric conveyor belt 35 for conveying the extraction detection dish 8;

[0061] This embodiment also discloses a method for using a sodium glucoheptonate content detection and extraction device, which further includes the following steps:

[0062] S1. Before testing, different batches of sodium glucoheptonate solutions are sampled and placed in different sample dishes 17. During the adsorption process, the extraction tube 26 gradually penetrates into the solution to ensure that each depth can be extracted;

[0063] S2, samples of different batches can be automatically extracted and dripped into the extraction and detection dish 8, and the extraction and detection dish 8 can be automatically unloaded after sampling;

[0064] S3, peeling the sample in the extraction and testing dish 8, weighing and recording it, and filtering out the extraction and testing dish 8 using a filtering device, and calculating the content of impurities in the total sample;

[0065] S4, then cooling the extraction test dish 8 to allow the sodium glucoheptonate therein to crystallize and precipitate, and weighing again to calculate the content of the sodium glucoheptonate.

[0066] In this embodiment: during the processing of the existing sodium glucoheptonate on the market, it is necessary to dissolve high-purity glucose in water and then slowly add sodium hydroxide to dissolve and stir. At this time, the temperature is heated to about 80 degrees, and then it will react to generate a solution containing sodium glucoheptonate and some insoluble impurities. At this time, it is cooled according to the crystallization temperature of sodium glucoheptonate to obtain sodium glucoheptonate crystals. During the production process, after the reaction generates a solution containing sodium glucoheptonate, in order to test whether the reaction is sufficient, a detection device is usually used to extract samples of the sodium glucoheptonate solution for detection, but the sampling process is usually complicated and inefficient. It usually takes a long time to detect large quantities of different batches of sodium glucoheptonate at the same time, which will cause the temperature of the sodium glucoheptonate solution after sampling to decrease, crystallize in advance, and affect the accuracy of the content of the solution sampling detection;

[0067] In order to avoid the above situation, it is necessary to increase the efficiency of large-scale detection. Therefore, before the detection, different batches of sodium glucoheptonate solution are sampled and placed in different sample dishes 17. Note that although the samples are extracted at this time, since it is a random sampling, there are more solutions and the solution volume is not the same. It is inaccurate to directly detect. At this time, it is necessary to start the transmission motor 2. After the transmission motor 2 is started, it rotates with the second horizontal axis 9 at the output end. During the rotation of the second horizontal axis 9, it rotates with the first gear 10. When the first gear 10 rotates, it rotates with the third gear 13 in the opposite direction through the meshing relationship;

[0068] At this time, the first gear 10 rotates with the third transverse axis 19 at its end, and the third transverse axis 19 rotates with the lifting frame 23. The inner wall of the third transverse axis 19 has a square profile cross section, and the cross section of the portion of the lifting frame 23 sliding on the inner wall of the third transverse axis 19 is also square, so they can rotate together. The lifting frame 23 rotates with the sampling tube 24 until the sampling tube 24 is placed at the opening of the sample dish 17, and the work of extracting the test sample can be carried out at this time;

[0069] It should be noted that, since the sample dish 17 contains a large amount of sampling solution and a high depth, extracting the solution at a single depth alone cannot represent the content and impurity rate of the entire solution. Therefore, in order to make the coverage depth of the extracted test sample more uniform, during the following movement of the sampling tube 24, the fifth horizontal axis 29 of the outer wall of the sampling tube 24 and the corresponding second ball 31 will slide along the first stable section 324 opened on the outer wall of the friction frame 22, and will enter the first descending section 321 during the sliding process. At the same time, the sixth horizontal axis 30 and the corresponding second ball 31 will move from the second stable section 331 to the fourth descending section 335. See attached Fig.12The positions in the other figures are not the initial positions of the working process. During this movement, the lifting frame 23 will slide down along the storage groove 191, and because the depth of the lowest point of the first descending section 321 is greater than the depth of the lowest point of the fourth descending section 335, that is, during the circular movement of the sampling barrel 24, the distance that the sixth horizontal axis 30 slides along the fourth descending section 335 is less than the distance that the fifth horizontal axis 29 slides along the first descending section 321 at the same distance. This will cause the sampling barrel 24 and the extraction tube 26 to move downward together, that is, in the process of continuously deepening the sample dish 17, the extraction tube 26 will be pulled downward. 6 will bring the piston 25 at its end to move upward along the inner wall of the sampling tube 24, causing the space between the piston 25 and the lower end of the sampling tube 24 to gradually increase. At this time, the negative pressure in this space will also increase, and an adsorption effect will be generated in the extraction tube 26 through the water outlet 27. The extraction tube 26 adsorbs the solution in the sample dish 17 through the lower opening. The solution is drawn into the extraction tube 26 and enters the space between the piston 25 and the lower end of the sampling tube 24 through the water outlet 27 for storage. It should be noted that during the adsorption process, the extraction tube 26 also gradually penetrates into the solution to ensure that every depth can be extracted;

[0070] After the extraction is completed, as the lifting frame 23 continues to rotate, the lifting frame 23 continues to rotate clockwise with the sampling tube 24 and the extraction tube 26. At this time, the fifth horizontal axis 29 and the sixth horizontal axis 30 move to the first ascending section 322 and the fourth ascending section 334 along the first descending section 321 and the fourth descending section 335 respectively. The first ascending section 322 and the fourth ascending section 334 are both in an ascending trend. Therefore, when the lifting frame 23 rotates at the same angle, the sixth horizontal axis 30 will rise more than the fifth horizontal axis 29 at this time, prompting the piston 25 The space between the piston 25 and the lower end of the sampling cylinder 24 gradually increases, and the negative pressure in this space also increases. This arrangement can prevent the liquid in the extraction tube 26 that has not passed through the water outlet 27 from dripping onto the table surface due to the disappearance of adsorption force during the rising process. The negative pressure in the space between the piston 25 and the lower end of the sampling cylinder 24 continues to rise. After the extraction tube 26 is separated from the liquid surface of the solution, the negative pressure continues to extract the liquid in the extraction tube 26 until the liquid in the extraction tube 26 completely passes through the water outlet 27 and enters the space between the piston 25 and the lower end of the sampling cylinder 24 for storage.

[0071] When the lifting frame 23 continues to rotate with the sampling cylinder 24 and the extraction tube 26, the fifth horizontal axis 29 and the sixth horizontal axis 30 will move from the first ascending section 322 and the fourth ascending section 334 to the second descending section 323 and the third descending section 332 respectively. At this time, the sampling cylinder 24 and the extraction tube 26 are directly above the extraction detection dish 8. When moving the same distance, the fifth horizontal axis 29 will drop less than the sixth horizontal axis 30. Therefore, at this time, the piston 25 moves downward in the sampling cylinder 24, and the piston 25 will move the piston 25 The solution in the space between the sampling tube 24 and the lower end is compressed, so that the solution enters the extraction tube 26 through the water outlet 27, and then drips from the extraction tube 26 into the extraction detection dish 8 below. In the process of dripping, the sampling tube 24 and the extraction tube 26 will move toward the extraction detection dish 8 to reduce the height difference between the extraction detection dish 8 and the extraction detection dish 8, so as to prevent the solution from splashing to the outside when dripping into the extraction detection dish 8 due to the large height difference. It should be noted that the lowest point of the extraction tube 26 is always higher than the highest point of the upper end of the extraction detection dish 8.

[0072] When the solution in the sampling tube 24 and the extraction tube 26 is completely discharged into the extraction detection dish 8, the fifth horizontal axis 29 and the sixth horizontal axis 30 also move from the second descending section 323 and the third descending section 332 to the fifth ascending section 325 and the third ascending section 333 respectively. The fifth ascending section 325 and the third ascending section 333 have the same ascending trend and the same ascending angle. Therefore, the fifth horizontal axis 29 and the sixth horizontal axis 30 move upward synchronously at this time, completing the sampling process of a single sample.

[0073] As the transmission motor 2 continues to rotate clockwise with the second horizontal axis 9, the first gear 10 will rotate with the third gear 13 in the opposite direction during the following rotation. At this time, the third gear 13 will gradually rotate the next sample dish 17 on the third gear 13, and the lifting frame 23 will also rotate synchronously until the extraction tube 26 and the next sample dish 17 are on the same vertical line, and the next extraction can be carried out. In the process of the rotation of the third gear 13, the second turntable 14 on which the sample dish 17 is placed will be moved in a circular motion, and the fourth gear 15 on the second turntable 14 will be prompted to pass through the fan-shaped gear ring 42 on the circular movement trajectory. At this time, as the second turntable 14 continues to move in a circular motion, the fourth gear 15 and the fan-shaped gear ring 42 are meshed with each other, prompting the fourth gear 15 to rotate the second turntable 14 in place, prompting the second turntable 14 to rotate with the sample dish 17 placed on the upper end, and the rotation will continue until the extraction of this sample dish 17 is completed, thereby increasing the extraction range during extraction and making subsequent data more accurate.

[0074] As the second horizontal axis 9 continues to rotate, the second horizontal axis 9 drives the second gear 11 to continue to rotate clockwise. During the rotation of the second gear 11, it meshes with the annular tooth groove 12 on the inner wall of the first turntable 5, prompting the first turntable 5 to rotate clockwise. The clockwise rotation of the first turntable 5 drives the extraction detection dish 8 on which the sample has been dripped to move clockwise. At this time, the continued rotation of the first turntable 5 will prompt the extraction detection dish 8 on which the sample has not been collected to gradually move to the position to be dripped, and the extraction detection dish 8 that has been dripped will make a circular motion with the movement of the first turntable 5 and finally conflict with the eighth horizontal axis 39, prompting the extraction detection dish 8 to slide at a uniform speed along the first inclined surface 6, and the eighth horizontal axis 39 will slide downward along the guide rod 37 with the slider 38 due to the reset force of the reset spring 40, so as to adapt to the sliding slope of the first inclined surface 6, and by The inclination of the first inclined surface 6 is gentle enough, and the liquid level collected in the extraction and detection dish 8 is much smaller than the opening of the extraction and detection dish 8, so leakage will not occur easily. When the extraction and detection dish 8 slides along the first inclined surface 6 and finally breaks away from the first inclined surface 6 and slides onto the surface of the electric conveyor belt 35, it should be noted that the electric conveyor belt 35 is in operation at the beginning, so the electric conveyor belt 35 can transport the sampled extraction and detection dish 8 to the specified position, and as the first turntable 5 continues to rotate, the eighth horizontal axis 39 will gradually resist and climb along the second inclined surface 7 opened on the outer wall of the first turntable 5. During the climbing process, the eighth horizontal axis 39 is resisted, thereby stretching the reset spring 40 with the slider 38 along the guide rod 37 to adapt to the slope of the second inclined surface 7, thereby realizing automatic unloading of the extraction and detection dish 8 and increasing the efficiency of batch sampling.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
