Description

Technical Field

[0001] The utility model relates to the technical field of geological survey, in particular to a microwave digestion device for soil sample processing. Background Art

[0002] Geological survey is the process of detailed exploration, research and analysis of natural resources such as rocks, minerals, soil, groundwater, etc. on and below the earth's surface. Its purpose is to understand the structure, composition, evolutionary history and characteristics of the earth's geological structure, so as to provide a scientific basis for various engineering projects, resource development, disaster prevention, etc.

[0003] Soil samples are a common medium in geological surveys. In the process of geological surveys, soil digestion is sometimes required, so a digestion device is essential. When the pressure in the storage tank of the existing digestion device is too high, it cannot self-adjust and the storage tank is inconvenient to place, which may cause the following problems:

[0004] Storage tanks cannot adjust themselves when the pressure is too high: Storage tanks in digestion devices are usually used to store samples under high temperature and high pressure. During the digestion process, the pressure in the storage tank may rise rapidly due to the release of gas or the generation of steam by heating. If the system is not designed with an effective pressure regulation mechanism, when the pressure is too high, the storage tank may not be able to automatically release the excess pressure, resulting in excessive pressure that may damage the equipment, cause leakage or even explosion and other dangerous accidents. In addition, failure to adjust the high pressure in time may also affect the accuracy of the experiment, because different pressure conditions will affect the progress of chemical reactions.

[0005] The tank is not convenient to place: The existing digestion device design may make the tank inconvenient to install and use. For example, the tank is too large, too heavy, or not easy to fix or move, or the installation process requires special tools and operating steps. These design shortcomings will increase the labor intensity of operators and even affect the efficiency of the experiment. For example, when it is necessary to quickly change samples or clean equipment, inconvenient operation will lead to a waste of time, and may even damage the equipment due to improper handling, affecting the normal progress of the experiment.

The specific connection and control sequence should refer to the working sequence between the electrical components in the following working principle to complete the electrical connection. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0033] See also Figure 1-4 The utility model provides a technical solution: a microwave digestion device for soil sample processing, comprising a box body 1, wherein a digestion chamber and a driving chamber are respectively provided on the upper and lower sides of the box body 1, a rotating structure is provided at the bottom of the digestion chamber, a card slot 2 is slidably installed on the rotating structure, a containing tank 3 is inserted in the card slot 2, a sealing cover is inserted on the top of the containing tank 3, a pressure relief plug is inserted on the sealing cover, and a plurality of microwave transmitters 4 are provided on the inner wall of the digestion chamber.

[0034] Embodiment 1: The rotating structure includes a turntable 5, which is rotatably arranged on the inner lower side of the digestion chamber. A connecting rod is rotatably installed between the digestion chamber and the driving chamber. The top end of the connecting rod is connected to the turntable 5, and a worm gear 6 is installed at the bottom end of the connecting rod. A motor 7 is installed in the driving chamber, and a worm 8 is installed at the rotating end of the motor 7. The worm 8 is meshed with the worm gear 6.

[0035] A plurality of nuts are embedded on the outer wall surface of the slot 2 , and a top screw 9 is spirally installed inside the nut. The top screw 9 passes through the inner wall of the slot 2 and contacts the containing tank 3 .

[0036] Specifically, in this embodiment, the rotating structure realizes the driving of the rotating structure inside the digestion chamber through the rotating disk 5 and the worm gear 6 and worm 8 mechanism. The motor 7 drives the worm gear 6 through the worm 8, thereby driving the rotation of the connecting rod, and driving the rotating disk 5 to rotate in the digestion chamber. The rotating disk 5 is equipped with a card slot 2, which is slidable to facilitate the removal and placement of the holding tank 3, and the holding tank 3 is inserted in the card slot 2. The rotating structure rotates the holding tank 3 so that the soil sample is evenly heated and processed during the digestion process, thereby improving the temperature uniformity during the digestion process and avoiding the phenomenon of local overheating or overcooling.

[0037] The rotating structure can make the sample be heated evenly during the digestion process, improve the digestion efficiency, and reduce the experimental error caused by uneven heating of the sample.

[0038] The rotating structure automatically adjusts the position of the containing tank 3, which reduces the complexity of manual operation and avoids the instability of the sample that may be caused by improper handling.

[0039] As the sealing of the container is improved, the chance of the sample being exposed to the outside air is reduced, thereby reducing the risk of contamination.

[0040] The design of the top screw 9 also increases the stability of the container 3 in the slot 2 and can accommodate containers 3 of various sizes.

[0041] Embodiment 2: The sealing cover comprises a cover body 10, which is buckled on the containing tank 3, and a plurality of buckles 11 are provided between the cover body 10 and the containing tank 3. A cylinder body 12 is provided at the bottom of the cover body 10, and a plurality of sealing rings 13 are embedded in the outer wall of the cylinder body 12. The sealing ring 13 contacts the inner wall of the upper port of the containing tank 3, and a groove is provided at the top of the cover body 10.

[0042] Specifically, in this embodiment, the sealing cover is composed of a cover body 10, a cylinder body 12 and a buckle 11. The cover body 10 is buckled with the upper end of the holding tank 3 through the buckle 11, and the cylinder body 12 is installed at the bottom of the cover body 10. The outer wall of the cylinder body 12 is embedded with a sealing ring 13, and the sealing ring 13 contacts the inner wall of the upper end of the holding tank 3 to ensure sealing. The sealing cover plays a role in sealing and isolating gas during the digestion process, preventing the leakage of harmful gas, and avoiding external pollution during the digestion process.

[0043] The sealing cover is designed with a buckle 11 and a sealing ring 13 to ensure that the gas under high temperature and high pressure conditions does not leak, effectively avoiding the diffusion of toxic gases during the digestion process and ensuring the safety of the operating environment.

[0044] The buckle 11 is designed to be simple and easy to use, and can be quickly assembled and disassembled, which reduces the burden on operators and improves the convenience of use of the equipment.

[0045] The design of the sealing cover ensures a closed environment for the sample during the digestion process, helps achieve the expected reaction conditions, and avoids the influence of the external environment on the experimental results.

[0046] The material of the sealing ring 13 can be silicone rubber, fluororubber or the like.

[0047] Embodiment three: The pressure relief plug includes a plug body 14, which is inserted on the cover body 10. An annular protrusion is integrally formed on the cover body 10 and located in the groove. The plug body 14 is inserted in the annular protrusion. The shape of the plug body 14 is an upward wedge. A cavity is opened in the plug body 14. A through opening is opened on the outer wall of the plug body 14 and located in the annular protrusion, and the through opening is connected with the cavity. An air inlet is opened at the bottom of the plug body 14, and the air inlet is also connected with the cavity.

[0048] A limit block 15 is provided on the top of the plug body 14 , and the limit block 15 contacts the upper edge of the annular protrusion. An annular gasket 16 is installed on the bottom of the plug body 14 .

[0049] Specifically, in this embodiment, the pressure relief plug is composed of a plug body 14, an annular protrusion and a stopper 15. The plug body 14 is inserted into the groove on the sealing cover and has a wedge-shaped structure. The inner cavity of the plug body 14 is connected to the external air inlet and the through port. The cavity in the plug body 14 is connected to the through port. When the pressure in the digestion chamber is too high, the pressure relief plug automatically releases the excess pressure through the wedge-shaped structure of the plug body 14, thereby ensuring the safety of the equipment under high pressure.

[0050] The pressure relief plug can automatically release pressure when the pressure in the digestion chamber is too high, avoiding equipment damage or safety accidents caused by high pressure and improving the safety of the equipment.

[0051] Through the design of annular protrusion, the pressure relief plug can effectively prevent gas leakage, while still maintaining sealing under high temperature and high pressure, ensuring the safety of the experimental environment.

[0052] The setting of the pressure relief plug can effectively control and regulate pressure changes, reduce equipment failures caused by overpressure, and extend the service life of the equipment.

[0053] Embodiment 4: An outer cover 17 is installed in the groove and outside the plug body 14. The outer cover 17 is an elastic body to prevent the gas discharged from the plug body 14 from leaking out.

[0054] Specifically, in this embodiment, the outer cover 17 is installed outside the pressure relief plug to prevent the gas discharged from the plug body 14 from leaking out. The outer cover 17 is made of an elastomeric material, which can effectively seal and protect the pressure relief plug and prevent the gas from affecting the outside world during pressure relief. The elastic design of the outer cover 17 enables it to adapt to different pressure changes and ensure the safety of gas discharge.

[0055] The elastic design of the outer cover 17 effectively seals the harmful gas that may be discharged by the pressure relief plug, thereby avoiding the harm of gas leakage to the operator or the environment.

[0056] The outer cover 17 can increase the sealing and protective performance of the pressure relief plug, ensure that the gas can be safely discharged during the pressure relief process, and reduce the risk of equipment failure or gas leakage.

[0057] The elastic outer cover 17 can automatically adjust according to pressure changes to provide more flexible and reliable protection.
