Description

Technical Field

[0001] This utility model relates to the field of molecular sieve technology, and in particular to a molecular sieve structure. Background Technology

[0002] When subjected to alternating pressure loads, the molecular sieve barrel cannot achieve absolute rigidity due to the complexity of its working environment and the inherent properties of the material. In practical applications, the barrel will inevitably undergo a certain degree of elastic deformation. Simultaneously, the particles inside the molecular sieve will also undergo slight changes due to inter-particle friction. Over time, this friction will cause some particles to gradually wear down into powder, thus affecting the overall performance of the molecular sieve.

[0003] Furthermore, silica gel, as a crucial component of molecular sieves, exhibits relatively poor high-temperature resistance. Under high-temperature conditions, silica gel is prone to thermal expansion and contraction. This contraction not only alters the physical structure of the molecular sieve but may also adversely affect its adsorption performance. Therefore, in practical applications, these factors must be fully considered, and appropriate measures must be taken to optimize the design and use of molecular sieves to ensure their stability and reliability under complex operating conditions.

Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0030] Example 1:

[0031] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The molecular sieve structure of this embodiment includes a sealed section 1, which is disposed inside the barrel 2 and forms a seal with the inner wall of the barrel 2. The arrangement of the sealed section 1 effectively prevents leakage during use, thereby ensuring the overall operational stability. Preferably, in actual use, by optimizing the fit clearance between the sealed section 1 and the barrel 2, unnecessary frictional wear can be reduced, extending the service life of the equipment. The sealed section 1 includes activated carbon 11 and a sealing component 12. The barrel 2 has an orifice 21 at one end, and the sealing component 12 is positioned closer to the orifice 21 than the activated carbon 11. The activated carbon 11 has good adsorption performance and a loose texture, which can absorb trace impurities and moisture that may be generated during the operation of the molecular sieve structure and stabilize the small particles inside the molecular sieve, ensuring the purity of the internal environment. At the same time, the interference fit between the activated carbon 11 and the inner wall of the barrel 2 also reduces the risk of leakage inside the molecular sieve to a certain extent.

[0032] Furthermore, the structure also includes a sealing plate 3 and an elastic element 4. The sealing plate 3 has a first connecting portion 31 on the side near the orifice 21, and one end of the elastic element 4 is connected to the first connecting portion 31, so that the sealing plate 3 and the elastic element 4 form an integral unit. The sealing plate 3 also fits into the orifice 21. When the sealing plate 3 is tightly fitted to the orifice 21, the alternating load generated during the movement of materials within the molecular sieve can be buffered by the action of the elastic element 4, thereby ensuring the stability of the structure. In actual operation, the disassembly of the sealing plate 3 also facilitates the maintenance or replacement of components inside the molecular sieve structure.

[0033] Furthermore, the sealing assembly 12 includes a first positioning member 121, which has a first rib 1211 and a second connecting portion 1212. The first rib 1211 is formed along the edge of the first positioning member 121 to the second connecting portion 1212. The arrangement of the first rib 1211 improves the structural stability of the first positioning member 121. One end of the elastic member 4 is also connected to the second connecting portion 1212, thereby enabling the transmission of force between the first positioning member 121, the elastic member 4, and the sealing plate 3. The movement of the material inside the barrel 2 of the molecular sieve is stabilized by the elastic deformation of the elastic member 4. Specifically, the increased adsorption pressure of the particles inside the barrel 2 of the molecular sieve causes expansion and deformation, resulting in gaps and loosening between the particles. Consequently, the activated carbon 11 and the first positioning element 121 exert forces on the elastic element 4 due to this expansion. The elastic element 4 then transmits these forces to the sealing plate 3. In this situation, the elastic element 4 consistently provides a continuously and dynamically changing pre-tightening pressure to the particles inside the barrel 2. When the adsorption process ends, the particles shrink and return to their original volume. At this point, the elastic element 4 rebounds accordingly, causing the activated carbon 11 near the particles inside the barrel 2 to maintain a certain contact pressure on the internal particles.

[0034] Furthermore, the sealing assembly 12 also includes a sealing ring 122. The first positioning member 121 has a recessed portion 1213 along its outer circumferential surface. The sealing ring 122 is disposed in the recessed portion 1213 and fits into the inner wall of the barrel 2. Through the arrangement of the sealing ring 122, combined with the design of the activated carbon 11, leakage of substances inside the barrel 2 is effectively prevented, improving the sealing performance. The first positioning member 121 also has a first filter cotton 5 disposed on the end face near the activated carbon 11. The arrangement of the first filter cotton 5 can prevent substances inside the barrel 2 from directly leaking out of the first positioning member 121. In addition, the design of the first filter cotton 5 is also conducive to air intake, effectively filtering dust exceeding the porosity of the first filter cotton 5.

[0035] Example 2:

[0036] The structural difference between Embodiment 2 and Embodiment 1 lies only in the replacement of the first positioning member 121 and the sealing ring 122. For details, please refer to the following documentation. Figure 3 and Figure 5The sealing assembly 12 further includes a second positioning member 123, which has a second rib 1231 and a third connecting portion 1232. The second rib 1231 is formed along the edge of the second positioning member 123 to the third connecting portion 1232. The first rib 1211 improves the structural stability of the first positioning member 121. One end of the elastic member 4 is also connected to the third connecting portion 1232, thereby enabling the transmission of forces between the second positioning member 123, the elastic member 4, and the sealing plate 3. The movement of the material inside the barrel 2 of the molecular sieve is stabilized by the elastic deformation of the elastic member 4. Similar to Embodiment 1, specifically, the increased adsorption pressure of the particles inside the molecular sieve's barrel 2 causes expansion and deformation, resulting in gaps and loosening between the particles. Therefore, the activated carbon 11 and the second positioning element 123 exert forces on the elastic element 4 due to the expansion, and the elastic element 4 then transmits these forces to the sealing plate 3. In this situation, the elastic element 4 consistently provides a continuously and dynamically changing pre-tightening pressure to the particles inside the barrel 2. When the adsorption process ends, the particles shrink and return to their original volume. At this time, the elastic element 4 rebounds accordingly, causing the activated carbon 11 near the particles inside the barrel 2 to maintain a certain contact pressure on the internal particles.

[0037] Furthermore, the sealing assembly 12 also includes a rubber ring 124, and the second positioning member 123 has an embedded portion 1233 along its outer circumferential surface. The rubber ring 124 covers the embedded portion 1233 and fits into the inner wall of the barrel 2. The rubber ring 124, combined with the activated carbon 11, effectively prevents leakage of substances inside the barrel 2, improving sealing performance. The second positioning member 123 also has a second filter cotton 6 on its end face near the activated carbon 11. The second filter cotton 6 prevents substances inside the barrel 2 from directly leaking out of the second positioning member 123. In addition, the design of the second filter cotton 6 facilitates air intake, effectively filtering dust exceeding the porosity of the second filter cotton 6.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
