Description

Technical Field

[0002] Carbon content determination is a technique used to determine the carbon content in a material. Carbon content usually refers to the total amount of carbon contained in the material, including organic and inorganic carbon. The purpose of determining carbon content is to determine the physical and chemical properties of the material, as well as its use and application range. There are many methods for carbon content determination, such as elemental analysis, combustion method, infrared spectroscopy, etc. Among them, elemental analysis is the most commonly used method, which can accurately determine the carbon content in the material;

[0003] When measuring the carbon content, the test sample needs to be ground, and then the operator needs to collect the ground test sample. However, when the current grinding device grinds the test sample, the test sample needs to be repeatedly ground to make the ground test sample uniform. Repeated grinding will cause part of the test sample to adhere to the inner wall of the grinding device, resulting in insufficient weight of the test sample and affecting the test efficiency.

[0025] S4: When the lifting frame moves, the toothed plate pushes the meshing ring to rotate in the center of the drying rack. When the meshing ring rotates, the connection between the cross and the positioning ring pushes the triangular plate to rotate. When the triangular plate rotates, it pushes the test sample to roll inside the drying rack.

[0026] The present invention has the following beneficial effects:

[0027] After the present invention places the test sample into the interior of the grinding component, the motor is started to drive the grinding component to grind the test sample. The polished test sample will fall into the interior of the weighing component, and the weighing component will be used to weigh the polished test sample. When the amount of the test sample is sufficient, the electric push frame will push the semicircular plate to move downward and contact with the surface of the high-temperature furnace. When the semicircular plate contacts the surface of the high-temperature furnace, the weighing component will enter the interior of the high-temperature furnace, and pour the polished test sample into the interior of the high-temperature furnace for combustion. After oxygen enters the interior of the high-temperature furnace through the grinding component, it mixes with the burning test sample to generate CO2. CO2 enters the interior of the infrared pool through the air pipe to absorb infrared energy. The energy absorbed by CO2 is proportional to its concentration. Therefore, the energy change of CO2 gas before and after flowing through the infrared absorber is measured, and the carbon content can be calculated. After CO2 enters the interior of the drying rack, the drying component can dry the CO2, thereby improving the accuracy of the test sample in carbon content testing.

[0028] After the test sample is poured into the interior of the grinding frame through the feed hole, the rotating rod drives the fixed frame to rotate as the motor rotates, and the fixed frame drives the crushing knife to grind the test sample when rotating. The crushed test sample will contact the bottom of the inner wall of the grinding frame and the bottom of the grinding ring. The grinding ring will grind the test sample when rotating, further improving the grinding effect of the test sample. The test sample that meets the sieve hole will fall into the inside of the weighing component for weighing, and the test sample that does not meet the sieve hole will be continuously polished by the grinding ring, so that the test sample can be fully polished.

[0029] After being polished, the test samples of the present invention will fall into the interior of the magnetic frame 1 and the magnetic frame 2 and contact the top of the measuring plate. After the test samples on the top of the measuring plate gradually increase, they will push the load-bearing rod to move downward. When the load-bearing rod moves downward, it will squeeze the weighing device so that the test samples with sufficient weight can enter the interior of the high-temperature furnace for combustion treatment. When the semicircular plate pushes the right-angle plate to move downward, the surface of the contact rod will contact the surface of the telescopic plate, and as the telescopic plate pushes the magnetic frame 1 and the magnetic frame 2 to separate from each other, the magnetic frame 2 pushes the measuring plate to tilt when moving. At this time, the test samples on the surface of the measuring plate will fall into the interior of the high-temperature furnace for combustion treatment.

[0030] The CO2 generated by the combustion of the test sample of the present invention will enter the interior of the air pipe through the air intake frame, and enter the interior of the drying rack through the air pipe for drying treatment. When the electric push frame moves up and down, the connection between the linkage frame and the vertical rod pushes the lifting frame to move. When the lifting frame moves, the tooth plate pushes the meshing ring to rotate at the center of the drying rack. When the meshing ring rotates, the connection between the cross and the positioning ring pushes the triangle plate to rotate. When the triangle plate rotates, it pushes the test sample to roll inside the drying rack, so that the test sample can be fully dried inside the drying rack. The heat generated by the dryer will be transmitted to the inside of the drying rod to dry the test sample. CO2 will enter the interior of the infrared pool through the filter frame to absorb infrared energy. The energy change of CO2 gas before and after flowing through the infrared absorber is used to measure the carbon content. When the cylindrical rod rotates, it drives the scraper to clean the filter frame to prevent the test sample from blocking the filter frame and affecting the flow of CO2.

[0031] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] When in use, after placing the test sample into the interior of the grinding component 20, start the motor 18 to drive the grinding component 20 to grind the test sample. The polished test sample will fall into the interior of the weighing component 21, and the weighing component 21 will be used to weigh the polished test sample. When the amount of the test sample is sufficient, the electric push frame 6 will push the semicircular plate 7 to move downward and contact the surface of the high-temperature furnace 8.

Therefore, by measuring the energy change of CO2 gas before and after flowing through the infrared absorber, the carbon content can be calculated. After CO2 enters the interior of the drying rack 15, the drying component 22 can dry CO2 to improve the accuracy of the test sample when testing the carbon content. After the test sample is poured into the interior of the grinding rack 30 through the feed hole 31, the rotating rod 36 drives the fixed rack 34 to rotate with the rotation of the motor 18.

The crushed test sample will contact the bottom of the inner wall of the grinding rack 30 and the bottom of the grinding ring 33. The grinding ring 33 will crush the test sample when it rotates. The grinding process further improves the grinding effect of the test sample. The test sample that meets the sieve hole 32 will fall into the inside of the weighing part 21 for weighing, and the test sample that does not meet the sieve hole 32 will be continuously polished by the grinding ring 33, so that the test sample can be fully polished. The polished test sample will fall into the inside of the magnetic suction frame 1 44 and the magnetic suction frame 2 51 and contact with the top of the measuring plate 43. After the test sample on the top of the measuring plate 43 gradually increases, it will push the load-bearing rod 48 to move downward. When the load-bearing rod 48 moves downward, it will squeeze the weighing device 49, so that the test sample with sufficient weight can enter the interior of the high-temperature furnace 8 for combustion. When the semicircular plate 7 pushes the right-angle plate 46 to move downward, the surface of the contact rod 47 will contact with the telescopic plate 41. The surfaces are in contact, and as the telescopic plate 41 pushes the magnetic frame 1 44 and the magnetic frame 2 51 to separate from each other, the magnetic frame 2 51 pushes the measuring plate 43 to tilt when moving. At this time, the test sample on the surface of the measuring plate 43 will fall into the interior of the high-temperature furnace 8 for combustion treatment. The CO2 generated by the combustion of the test sample will enter the interior of the air pipe 13 through the air intake frame 19, and enter the interior of the drying rack 15 through the air pipe 13 for drying treatment. When the electric push frame 6 moves up and down, the connection between the linkage frame 5 and the vertical rod 60 pushes the lifting frame 61 to move. When the lifting frame 61 moves, it pushes the meshing ring 62 to rotate at the center of the drying rack 15 through the tooth plate 63. When the meshing ring 62 rotates, it pushes the triangular plate 71 to rotate through the connection between the cross 66 and the positioning ring 69.When the triangular plate 71 rotates, it pushes the test sample to roll inside the drying rack 15, so that the test sample can be fully dried inside the drying rack 15. The heat generated by the dryer 70 will be transmitted to the inside of the drying rod 65 to dry the test sample. CO2 will enter the infrared pool 4 through the filter rack 68 to absorb infrared energy. The energy change of CO2 gas before and after passing through the infrared absorber is used to measure the carbon content. When the cylindrical rod 64 rotates, it drives the scraper 67 to clean the filter rack 68 to prevent the test sample from blocking the filter rack 68 and affecting the flow of CO2.
