DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application.

[0029] Embodiment 1

[0030] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4For the first embodiment of the utility model, this embodiment provides a novel solid digestion tank, including tank body 1, the outer surface of tank body 1 is connected with sealing mechanism 2 by screw thread, the outer surface of sealing mechanism 2 is equipped with pressure relief mechanism 3, pressure relief mechanism 3 includes the gas outlet hole 302 being equipped in the outer surface of cover shell 203, the inner wall of gas outlet hole 302 is connected with sealing ball 303 slidingly, and the outer surface of cover shell 203 is fixedly connected with protective cover 301, wherein tank body 1 adopts polytetrafluoroethylene material, polytetrafluoroethylene has extremely stable chemical structure, hardly reacts with any chemical substance, in digestion experiment, corrosive reagent such as strong acid (such as nitric acid, sulfuric acid), strong base (such as sodium hydroxide) and strong oxidizing agent (such as perchloric acid) is often used, and the digestion tank of polytetrafluoroethylene material can resist the erosion of these reagents, and will not be corroded, dissolved or chemically reacted, so as to ensure the integrity and service life of the digestion tank.

[0031] Specifically, the outer surface of protective cover 301 wraps the outer surface of gas outlet hole 302, the inner wall of gas outlet hole 302 is fixedly connected with sealing block 304, the upper surface of sealing block 304 is attached to the outer surface of sealing ball 303, and cover shell 203, first sealing protrusion 205, fixed block 204 and second sealing protrusion 206 are manufactured by integral injection molding process, forming an indivisible whole structure. In the integral injection molding process, these components are injection molded at one time, seamlessly connected with each other, while ensuring structural stability, effectively avoiding the problems of gaps, misalignment and the like caused by assembly splicing, greatly improving the sealing performance and overall reliability of the product.

[0032] Further, through the double-sealing design of first sealing protrusion 205 and second sealing protrusion 206, and the enhanced sealing performance of the weighted cover shell 203, the gas leakage in tank body 1 is effectively prevented, ensuring the safety of the experimental environment and the stability of the reaction. At the same time, pressure relief mechanism 3 can be started in time when the pressure in the tank is too high, realizing safe pressure relief through the separation of sealing ball 303 and sealing block 304, avoiding the occurrence of dangerous situations such as the rupture of tank body 1 caused by excessive pressure, and ensuring the safety of experimental equipment and personnel.

[0033] Embodiment 2

[0034] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 For the second embodiment of the utility model, based on the previous embodiment, sealing mechanism 2 includes cover shell 203 connected to the outer surface of tank body 1 by screw thread, the inner wall of cover shell 203 is fixedly connected with fixed block 204, the lower surface of fixed block 204 is fixedly connected with first sealing protrusion 205 and second sealing protrusion 206.

[0035] The lower surface of the first sealing protrusion 205 is attached to the upper surface of the tank body 1, the inner wall of the tank body 1 is attached to the outer surface of the second sealing protrusion 206, the outer surface of the cover shell 203 is fixedly connected with a plurality of groups of fixed protrusions 202, and the fixed protrusions 202 are uniformly arranged on the outer surface of the cover shell 203. The outer surface of the cover shell 203 is fixedly connected with a tacky adhesive 207, and the outer surface of the tacky adhesive 207 is attached with a plastic film 201.

[0036] The fixed protrusions 202 on the outer surface of the cover shell 203 greatly increase the friction between the hand and the cover shell 203, making the separation and installation operation of the cover shell 203 and the tank body 1 more relaxed and labor-saving, and improving the efficiency of the experimental operation. In addition, the design of the tacky adhesive 207 and the plastic film 201 facilitates the marking of the tank body 1, helps the experimental personnel to quickly identify the information such as the raw materials and the experimental state in the tank body 1, and is convenient for the recording and management of experimental data, and improves the standardization and traceability of the overall experimental process.

[0037] Working principle: First, prepare the work, carefully add the solid raw materials that need to be processed into the tank body 1. Then, connect the cover shell 203 with the tank body 1. Since the cover shell 203 and the tank body 1 are threadedly connected, accurate tightening operation can be achieved during the rotation of the cover shell 203. As the cover shell 203 is gradually tightened, the first sealing protrusion 205 and the second sealing protrusion 206 fixed on the inner wall of the cover shell 203 begin to play a role. The lower surface of the first sealing protrusion 205 is tightly attached to the upper surface of the tank body 1, and the outer surface of the second sealing protrusion 206 is tightly attached to the inner wall of the tank body 1, forming a double sealing structure, and the presence of the fixed block 204 not only plays a role in connecting the first sealing protrusion 205 and the second sealing protrusion 206, but also increases the weight of the cover shell 203. The heavy cover shell 203 exerts greater pressure on the tank body 1 by virtue of its own gravity, making the contact between the cover and the tank body 1 more closely, thereby significantly enhancing the sealing performance. During the operation process such as digestion, various gases will be generated inside the tank body 1, causing the pressure to gradually rise. At this time, the sealing structure can effectively prevent the gas from escaping, ensuring that the reaction is carried out in a stable environment.

[0038] When the pressure in the tank 1 continues to rise to a certain extent, the internal pressure will lift the sealing ball 303 in the air outlet hole 302 upward. The sealing ball 303 is originally in close contact with the upper surface of the sealing block 304, and under the action of pressure, the two are separated, and the gas can be discharged through the air outlet hole 302 to realize the pressure relief operation of the tank 1. The protective cover 301 fixed on the outer surface of the cover shell 203 wraps the outer surface of the air outlet hole 302, effectively preventing the sealing ball 303 from being separated from the air outlet hole 302 due to external force or airflow impact during pressure relief, ensuring the normal operation and safety of the pressure relief mechanism 3. The outer surface of the cover shell 203 is pre-fixed with the tacky adhesive 207, and the outer surface of the tacky adhesive 207 is in close contact with the plastic film 201. Only by separating the plastic film 201 from the tacky adhesive 207, the label with relevant information can be pasted on the outer surface of the tacky adhesive 207, so as to clearly mark the tank 1, and facilitate the identification and management of the experimental personnel. In addition, the plurality of groups of fixed protrusions 202 uniformly arranged on the outer surface of the cover shell 203 also bring convenience to the operation. When the cover shell 203 and the tank 1 need to be separated, the hands of the experimental personnel contact the fixed protrusions 202, and the fixed protrusions 202 increase the friction between the outer surface of the cover shell 203 and the hands, so that the operation of rotating the cover shell 203 is more easy and stable, and the slipping phenomenon is not easy to appear.

[0039] It should be noted that in this text, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations.
