Description

Technical Field

[0001] This utility model relates to the field of soil testing and waste discharge technology, and in particular to an automatic waste discharge mechanism for a soil testing graphite digestion instrument. Background Technology

[0002] The graphite digestion instrument for soil testing is a specialized instrument for digesting soil samples. Utilizing the excellent thermal conductivity and stability of graphite, the graphite block is electrically heated to a set temperature. A digestion tube containing the soil sample and digestion reagent is then inserted into the hole of the graphite block. Under the combined action of the high temperature and the digestion reagent, a chemical reaction occurs, decomposing the complex components in the soil, such as organic matter and minerals, and converting the analyte elements into easily analyzable ionic states. During the digestion process, the graphite digestion instrument will produce acid mist and harmful gases.

[0003] For example, CN221230258U discloses a waste gas treatment device for a graphite digester, including a waste gas treatment chamber, which is divided into several waste gas treatment modules. Each waste gas treatment module is provided with an inlet bend and an outlet. A pull-out plate is provided at the outlet. A connecting pipe is provided in the middle of the waste gas treatment chamber. The connecting pipe is provided with a connecting hole that can connect all waste gas treatment chambers. Slides are provided on the inner walls of the waste gas treatment chambers near the connecting pipe. A sealing plate is slidably connected to the slide. One end of the inlet bend is embedded in a sealing ring. The sealing ring is fixed by a clamp. The clamp is installed on the inner wall of the outer shell. One end of the inlet pipe is embedded in the sealing ring. The other end of the inlet pipe passes through the outer shell and connects to the graphite digester. An exhaust pipe is provided at the other end of the outer shell.

[0004] However, in the existing technology, the waste gas generated during the graphite digestion process is mainly the gas produced by the volatilization of digestion reagents and the decomposition of organic matter in the sample. As the usage time increases, the purification materials (activated carbon, catalysts, etc.) in the waste gas purification equipment will gradually become saturated or ineffective. Traditional purification devices are inconvenient to replace purification materials. If these purification materials are not replaced or regenerated in time, the waste gas purification effect will be greatly reduced, and it will be unable to effectively remove pollutants from the waste gas. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model provides an automatic waste discharge mechanism for a graphite digester for soil testing, including a waste gas collection shell 1. Both sides of the waste gas collection shell 1 are fixedly connected to docking pipes 3. The top of the waste gas collection shell 1 is covered with a sealing cover 2. A filter element 6 is fixedly installed on the lower surface of the sealing cover 2. A positioning frame 5 is fixedly installed on the inner wall of the waste gas collection shell 1. The filter element 6 is inserted into the inside of the positioning frame 5. Support rods 7 are fixedly installed at the four corners of the sealing cover 2. A docking frame 8 is fixedly installed at the bottom of the waste gas collection shell 1. The support rods 7 are inserted into the inside of the docking frame 8. A support platform 10 is fixedly installed at the center of the waste gas collection shell 1. A rotating rod 13 is symmetrically rotated on the top of the support platform 10. One end of the rotating rod 13 is fixedly connected to a transmission rod 14. One end of the transmission rod 14 is movably connected to one end of the support rod 7.

[0025] A docking plate 4 is fixedly installed on the outer wall of the exhaust gas collection shell 1, and the docking plate 4 is located between two docking pipes 3;

[0026] The bottom of the support rod 7 has a notch 9, one end of the transmission rod 14 is located inside the notch 9, and a protrusion 15 is fixedly installed inside the notch 9. One end of the transmission rod 14 is movably connected to the protrusion 15.

[0027] The specific setup and function of this embodiment are described below. The exhaust gas collection housing 1 is installed into the graphite digester through the docking plate 4. One side of the docking pipe 3 is connected to the exhaust pipe in the graphite digester, and the other side of the docking pipe 3 is connected to the gas collection device. The exhaust gas generated when the graphite digester is operating will enter the exhaust gas collection housing 1. The sealing cover 2 covers the exhaust gas collection housing 1, and the filter element 6 on its lower surface is inserted into the positioning frame 5. The exhaust gas in the exhaust gas collection housing 1 is purified by the filter element 6 and then discharged into the collection device.

[0028] After prolonged use, the filter element 6 will gradually fail. At this time, the exhaust gas collection housing 1 is removed, and the transmission rod 14 is driven by rotating the rotating rod 13. The transmission rod 14 is used to push the support rod 7 out of the docking frame 8, thereby lifting the sealing cover 2. During the upward movement of the sealing cover 2, the filter element 6 will be pulled out of the positioning frame 5. This method can effectively reduce the difficulty of replacing the filter element 6 and will not affect the stability of each structure.

[0029] The filter element 6 is installed on the lower surface of the sealing cover 2 by bolts. After replacing the filter element 6, the sealing cover 2 is put back on the exhaust gas collection housing 1. The support rod 7 is inserted into the docking frame 8, and the filter element 6 is put into the positioning frame 5. The positioning frame 5 has through holes on all four sides to allow air to come into contact with the filter element 6.

[0030] The transmission rod 14 is a U-shaped rod, and the protrusion 15 is located in the U-shaped groove of the transmission rod 14. During the rotation of the transmission rod 14, the support rod 7 will be lifted by the protrusion 15. The presence of the notch 9 and the U-shaped groove provides sufficient space for the transmission rod 14 to move.

[0031] Example 2: Figure 3 , Figure 4 and Figure 5 As shown, a worm gear 16 is rotatably installed inside the support platform 10. The worm gear 16 is set to a vertical state. A worm wheel 11 is fixedly installed on the outer wall of the rotating rod 13. The worm wheel 11 is meshed with the worm gear 16. Limiting platforms 12 are fixedly installed on both sides of the bottom of the exhaust gas collection housing 1. The rotating rod 13 is rotatably installed inside the limiting platform 12.

[0032] The overall effect of this embodiment is that the worm 16 is meshed with the worm wheel 11, and one end of the worm 16 extends to the outside of the exhaust gas collection housing 1, which is convenient for personnel to operate. In use, the worm 16 is rotated to drive the worm wheel 11, thereby driving the rotating rod 13. The stability of this device is improved by the transmission of the worm wheel 11 and the worm 16. At the same time, the self-locking function of the worm wheel 11 and the worm 16 ensures the stability of the sealing cover 2 on the exhaust gas collection housing 1.

[0033] The usage method and working principle of this device: The exhaust gas collection housing 1 is installed into the graphite digester through the docking plate 4. One side of the docking pipe 3 is connected to the exhaust pipe in the graphite digester, and the other side of the docking pipe 3 is connected to the gas collection device. The exhaust gas generated when the graphite digester is operating will enter the exhaust gas collection housing 1. The positioning frame 5 has through holes on all four sides to allow air to come into contact with the filter element 6. The exhaust gas is purified by the filter element 6 and then discharged into the collection device.

[0034] After prolonged use, the filter element 6 will gradually fail. At this time, the exhaust gas collection housing 1 is removed from the graphite digester. The rotating rod 13 is driven by the worm gear 16 meshing with the worm wheel 11, which drives the rotating rod 13 and the transmission rod 14 at its end. During the rotation of the transmission rod 14, the support rod 7 will be lifted by the protrusion 15, and the sealing cover 2 will be removed from the exhaust gas collection housing 1. During the upward movement of the sealing cover 2, the filter element 6 will be pulled out from the positioning frame 5.

[0035] The filter element 6 is installed on the lower surface of the sealing cover 2 by bolts. After replacing the filter element 6, the sealing cover 2 is put back on the exhaust gas collection housing 1. The support rod 7 is inserted into the docking frame 8, so that the protrusion 15 re-enters the U-shaped groove of the transmission rod 14. Finally, the worm gear 16 is rotated in the opposite direction to press the support rod 7 into the docking frame 8, so that the filter element 6 re-enters the positioning frame 5.
