A manually controlled device for precise release of adsorbent material and its release method

Abstract

This invention relates to a manually controlled device and method for precisely releasing adsorbent materials. The device includes a vacuum port, a superconducting container, a cantilever, adsorbent material, a vacuum container, a first sealing ring, a pull rod cap, and a second sealing ring. The vacuum container is located inside the superconducting container and connected to it via the cantilever. The vacuum port is fixed to the vacuum container. One end of the vacuum container is open, and the pull rod cap and the first sealing ring are located at the open end of the vacuum container. One end of the pull rod cap seals the adsorbent material inside the vacuum container, while the other end of the pull rod protrudes outside the superconducting container, allowing the operator to manually control the pull rod cap to slide and release the adsorbent material. Compared to existing technologies, this invention allows for manual control of the adsorbent material release, preventing premature loosening of the cap due to a decrease in pressure difference, thus making the release of the adsorbent material more precise.

Description

Technical Field

[0001] This invention relates to the field of vacuum technology, and in particular to a manually controlled device for the precise release of adsorbent materials and a release method thereof. Background Technology

[0002] Vacuum treatment is a common method for handling cavities in industrial fields. Any material exposed to a vacuum for an extended period will inevitably experience gas release, causing a decrease in the vacuum level of the vacuum chamber. Therefore, for long-term use of vacuum containers, adsorbent materials must be added to mitigate the vacuum degradation caused by gas release. How to release adsorbent materials under vacuum has long been a challenge in the vacuum field. The traditional method involves quickly adding the adsorbent material before sealing the vacuum chamber and then immediately evacuating. However, no matter how quickly, the adsorbent material will still experience varying degrees of decrease in adsorption efficiency due to contact with air, and the process cannot be standardized due to differences in operator procedures.

[0003] Researchers in the field of vacuum have proposed many methods, but the most ideal method must be the logic of "treating the adsorbent material in a vacuum, maintaining the vacuum environment after treatment, and then placing it into the target container when the target container is in a vacuum state".

[0004] Chinese patent application CN118770756A discloses a vacuum adsorbent material dispensing device and its release method. The dispensing device includes a vacuum chamber, within which a vacuum container is disposed, and a cantilever connects the vacuum container and the vacuum chamber. Adsorbent material is stored in the vacuum container, and a vacuum extraction port is located at the upper end of the vacuum container. A vacuum is created through the vacuum extraction port to maintain a vacuum environment within the vacuum container. The vacuum container is equipped with a cap and a sealing ring, which serve as release ports for the adsorbent material and are located at the lower end of the vacuum container. The pressure difference between the inside and outside of the vacuum chamber is changed by evacuating the vacuum chamber, which is used to open and close the vacuum container and dispense the adsorbent material. This technical document addresses a similar problem to this invention, but because it employs a pressure difference method, although theoretically feasible, its effectiveness is minimal. This is because the pressure change is linear during the vacuum extraction process. Therefore, before the vacuum reaches the target pressure of this technical document, the gradual decrease in the internal and external pressure difference causes the cap to loosen prematurely, leading to its detachment. Therefore, in actual operation, the release time of the solution proposed in this technical document is significantly advanced, and the adsorbent material using this release method will still experience significant deterioration, failing to fundamentally solve the problem of adsorbent deterioration during release.

[0005] Chinese patent application US20040141850A1 discloses a vacuum adsorption material dispensing device and its release method. The dispensing device includes a vacuum chamber containing a vacuum container. The vacuum container can be made of brittle material, deformable material, or rigid material. When using brittle material, the patent utilizes the deformation of two plates to "crush" a small bottle made of the brittle material. It specifically notes that if the bottle fails to break in time, the plates need to be manually struck to break it. Brittle material generates a large number of particles during the fracture process. Vacuum containers typically require periodic maintenance (i.e., re-vacuuming) during long-term use. These particles are drawn into the vacuum pump during maintenance. Vacuum pumps should avoid sucking in solids; if solids are sucked in, the pump blades (especially polymer pumps) will be damaged, increasing equipment depreciation and maintenance costs. When using deformable material, the patent utilizes the pressure difference between the inside and outside, causing a balloon to inflate. Upon contact with a spike, the balloon is "punctured," releasing the contents. Currently available deformable flexible materials all exhibit some degree of gas release under vacuum. Placing such materials in a vacuum causes the vacuum to deteriorate continuously, increasing maintenance costs and intervals. In contrast, this patent explicitly states that the contents of rigid materials must be fixed within the container. The "release" mechanism is essential in this patent because, in a vacuum, the larger the contact area between common adsorbent materials like molecular sieves and the surrounding space, the stronger their adsorption capacity. Therefore, scattering the adsorbent material within the container through "detachment" maximizes its performance. If the adsorbent material were made as shown in the prior art, its contact area with the external space would be significantly reduced, drastically decreasing its adsorption capacity. From an engineering perspective, this is not a mature solution. Furthermore, because this patent uses a thin film and spring as the release mechanism in the case of rigid materials, it also suffers from the premature release of the adsorbent material seen in Chinese patent application CN118770756A, inevitably leading to deterioration of the adsorbent material. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art by providing a manually controlled device and method for precisely releasing adsorbent materials, which can achieve precise release of adsorbent manually using only a lever without the need for any heating device.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A manually controlled device for precise release of adsorbent material includes a superconducting container and an adsorbent material. The superconducting container is a vacuum space in a device with a vacuum structure, and the container wall has through holes. The device also includes: a vacuum port, a cantilever, a vacuum container, a first sealing ring, a pull rod cover, and a second sealing ring. The vacuum container is inside the superconducting container and is connected to the superconducting container through the cantilever. The vacuum port is fixed to the vacuum container, and the second sealing ring is fixed to the through holes of the superconducting container.

[0009] The vacuum container is open at one end, and the pull rod cover and the first sealing ring are set at the open end of the vacuum container. The cover end of the pull rod cover seals the adsorbent material in the vacuum container, and the pull rod end passes through the through hole of the superconducting container and the second sealing ring, and is exposed outside the superconducting container for the operator to manually control the pull rod cover to slide and release the adsorbent material.

[0010] Furthermore, the device also includes a pull rod buckle, which is fixed to the pull rod of the pull rod cover outside the superconducting container.

[0011] Furthermore, the shape of the vacuum container and the pull rod cover changes according to the shape of the superconducting container, and the connection position and connection method of the cantilever to the vacuum container or the superconducting container change according to the shape of the vacuum container or the superconducting container.

[0012] Furthermore, the surface of one end of the pull rod of the pull rod cover is smooth.

[0013] Furthermore, the pull rod cover, the second sealing ring, and the superconducting container form a sealed structure in which no medium exchange or flow occurs between the inner and outer spaces.

[0014] Furthermore, before the pull rod cover slides, the pull rod cover, the first sealing ring, the vacuum port, and the vacuum container form a sealed structure in which the inner and outer spaces will not experience media exchange or flow.

[0015] A method for releasing adsorbent material based on the above-mentioned manually controlled precise release device for adsorbent material, the method comprising:

[0016] Step S1: Set up a device for precise release of adsorbent material;

[0017] Step S2: Evacuate the superconducting container to a vacuum state;

[0018] Step S3: Pull the lever to seal the cover and release the adsorbent material inside the vacuum container.

[0019] Furthermore, in step S1, the specific process of setting up the precise release device for the adsorbent material includes:

[0020] Step S101: According to the shape and size of the superconducting container, change the shape, size, hardness and material of the vacuum container. The shape of the vacuum container should conform to the pressure vessel design standard formula.

[0021] Step S102: Determine whether the pull rod buckle is needed to fix the pull rod cover to the vacuum container by calculating the quantitative formula of the vacuum container.

[0022] Step S103: Place the adsorbent material into the vacuum container and seal the vacuum container using a pull rod cap and a first sealing ring;

[0023] Step S104: The vacuum container is evacuated to a vacuum state through the vacuum port, and the vacuum container is fixed in the superconducting container using a cantilever.

[0024] Furthermore, the quantitative formula for the vacuum container includes:

[0025]

[0026] Where k1 is the mass of the adsorbent material, k2 is the mass of the pull rod cap, μ is the coefficient of friction, S is the cross-sectional area of ​​the capping end of the pull rod cap, p is the internal and external pressure difference, and g is the gravitational constant.

[0027] Furthermore, if the calculated mass of the tie rod cover is less than the actual mass of the tie rod cover, then a tie rod clip needs to be added.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The device described in this invention is designed with a manually controllable lever cap. When using this device, the lever is exposed outside the superconducting container, allowing the operator to manually control the sliding of the lever cap and release the adsorbent material. This makes the release of the adsorbent material under human control, and the cap will not loosen prematurely due to the decrease in pressure difference, making the release of the adsorbent material more precise, simple and effective.

[0030] 2. This invention is under human control and does not require any heating device. The release of the adsorbent material can be manually controlled by simply using a lever when the superconducting container completes vacuum extraction. This avoids the deterioration of the adsorbent material, improves its performance, and is easy to operate. It can effectively prevent the adsorbent material from coming into contact with air during release, thus achieving a reliable adsorption effect. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0043] Example 1

[0044] This embodiment aims to disclose a manually controlled device for precise release of adsorbent material, the device being as follows: Figure 1As shown, it includes a vacuum extraction port 1, a superconducting container 2, a cantilever 3, an adsorption material 4, a vacuum container 5, a first sealing ring 6, a pull rod cover 7, and a second sealing ring 8.

[0045] The superconducting container 2 is a vacuum space within a device with a vacuum structure. The vacuum cavity refers to the vacuum space within commercially available and engineered devices with vacuum structures. The adsorbent material 4 is an adsorbent material placed within the device's vacuum structure to mitigate the deterioration of the vacuum level caused by container venting.

[0046] Vacuum container 5 is inside superconducting container 2 and is connected to superconducting container 2 via cantilever 3. Cantilever 3 is usually also inside superconducting container 2 and is a rigid body.

[0047] Vacuum port 1 is fixed to vacuum container 5, and vacuum container 5 evacuates the internal environment through vacuum port 1.

[0048] One end of the vacuum container 5 is open, and the pull rod cover 7 and the first sealing ring 6 are located at the open end of the vacuum container 5.

[0049] One end of the pull rod cap 7 seals the adsorbent material 4 inside the vacuum container, while the other end of the pull rod cap 7 passes through the second sealing ring 8 on the superconducting container 2, protruding outside the superconducting container 2. The operator can release the adsorbent material 4 by pulling the pull rod cap 7, causing it to slide outward. The surface of the pull rod end of the pull rod cap 7 is smooth.

[0050] The pull rod cover 7, the second sealing ring 8 and the superconducting container 2 form a sealed structure in which no medium exchange or flow occurs between the inner and outer spaces. Similarly, before the pull rod cover 7 slides, the pull rod cover 7, the first sealing ring 6, the vacuum port 1 and the vacuum container 5 form a sealed structure in which no medium exchange or flow occurs between the inner and outer spaces.

[0051] The first sealing ring 6 and the second sealing ring 8 are rubber O-rings, made of materials including nitrile rubber and fluororubber, with a vacuum sealing degree of 10. -5 If the superconducting container 2 requires a higher vacuum, a metal sealing ring will be used instead.

[0052] The shapes of the vacuum container 5 and the pull rod cover 7 are changed according to the shape of the superconducting container 2. Under the premise of ensuring the normal operation of the first sealing ring 6, different sizes and shapes can be set according to different engineering practice scenarios, including but not limited to irregularly shaped vacuum cavities with varying cross-sections.

[0053] The shape and size of the vacuum container 5, which serves as the container for the adsorbent material 4, have no effect on the release of the adsorbent material 4. The shape of the vacuum container 5 should conform to the standard formula for pressure vessel design. The material of the vacuum container 5 includes stainless steel, epoxy resin, or other high-strength materials that will not break or break due to vacuum negative pressure, have a low outgassing rate, and can reduce the rate of vacuum deterioration.

[0054] The standard formula for pressure vessel design is as follows:

[0055]

[0056] Where S is the vessel wall thickness, P is the design pressure, D is the diameter, and δ t It is the allowable stress at the design temperature, φ is the welding coefficient, which is taken as 1.0 here, and C is the corrosion allowance.

[0057] As a supporting component for the vacuum container 5, the cantilever 3 only provides support for the vacuum container 5. Therefore, the connection position and method between the cantilever 3 and the vacuum container 5 or the superconducting container 2 can be changed according to the shape of the vacuum container 5 or the superconducting container 2, such as placing it on the side or directly connecting it to the superconducting container 2. However, the position of the cantilever 3 must not obstruct the opening of the vacuum container 5. For scenarios that require frequent disassembly, the cantilever 3 can also be designed as a quick-connect structure such as a hook or a buckle.

[0058] In this embodiment, the vacuum container 5 is U-shaped and the pull rod cover 7 is flat, which can better release the adsorbent material 4.

[0059] When placing this device into an integrated container, it needs to be inserted during the manufacturing process. For non-integrated containers, it can be inserted after manufacturing is complete. The insertion process includes: passing the pull rod through the sealing hole, moving the vacuum container containing the adsorbent material close to the sealing hole, and then connecting the cantilever. Since the cantilever connection method is unrestricted, this process can be followed for both integrated and non-integrated containers.

[0060] Example 2

[0061] Based on Embodiment 1 above, this embodiment designs another manually controlled device for precise release of adsorbent material. The difference between this device and Embodiment 1 is that the vacuum container 5 and the pull rod cap 7 have different shapes.

[0062] Generally, for common adsorbent materials 4 such as molecular sieves, the larger the contact area with space, the better the adsorption effect. Conversely, if the adsorbent material 4 aggregates together, the adsorption effect will be greatly reduced. However, some adsorbent materials 4, such as hydrogen absorbers, have small particles. If they are allowed to disperse, during vacuum maintenance of the superconducting container 2, the small hydrogen absorber particles may enter the vacuum pump used for vacuuming with the airflow, damaging the vacuum pump, reducing its lifespan, and increasing maintenance costs.

[0063] like Figure 2 As shown, the vacuum container 5 in this embodiment is flat, and the pull rod cover 7 is U-shaped. After the superconducting container 2 reaches the specified vacuum level, the pull rod cover 7 is pulled down to bring the built-in adsorbent material into contact with the vacuum of the superconducting container 2. Although the adsorption effect is reduced to some extent, the U-shaped container can effectively prevent the internal adsorbent material from scattering.

[0064] The remaining part of the precise release device for adsorbent material in this embodiment is the same as that in Embodiment 1. For specific details, please refer to the relevant descriptions and effects in Embodiment 1 for understanding.

[0065] Example 3

[0066] Based on the above embodiments, this embodiment designs another manually controlled device for precise release of adsorbent materials. The difference between this device and the above embodiments is that the device in this embodiment also includes a superconducting vacuum extraction port 9 and a superconducting vacuum extraction port cover 10.

[0067] Figure 1 and Figure 2 In the process, the pull rod cover 7 achieves vacuum sealing by opening a vacuum interface on the superconducting container 2 and using a second sealing ring 8, thus enabling the pull rod operation. However, if... Figure 3 As shown, in this embodiment, the existing superconducting vacuum port 9 on the superconducting container 2 (i.e., the device with a vacuum structure) is used to arrange the vacuum container 5 and the pull rod cover 7. The superconducting vacuum port 9 is the original port used for vacuuming on the device with a vacuum structure. The pull rod cover 7, the superconducting vacuum port 9, the superconducting vacuum port cover 10, and the superconducting container 2 form a sealed structure in which no medium exchange or flow occurs between the inner and outer spaces.

[0068] By using the existing superconducting vacuum extraction port 9 to arrange the vacuum container 5, the need to add a vacuum extraction port to the superconducting container 2 can be avoided.

[0069] When using the device of this embodiment for precise release of adsorbent material, devices with vacuum structures require the use of a three-way connector to extract air during subsequent vacuum evacuation via the vacuum port. This prevents the quality and efficiency of vacuum extraction from affecting the pull rod sealing cap 7. Furthermore, this device is more suitable for containers such as terminals and liquid nitrogen tanks, where the adsorbent material only needs to be scattered at the bottom to achieve a good adsorption effect. Large-scale deployment reduces the impact of adsorbent material degradation.

[0070] The remaining parts of the precise release device for adsorbent material in this embodiment are the same as those in the above embodiments. For specific details, please refer to the relevant descriptions and effects in the above embodiments for understanding.

[0071] Example 4

[0072] This embodiment, based on the above embodiments, designs another manually controlled device for precise release of adsorbent material. Its structure differs from the above embodiments in that, as follows: Figure 4 As shown, the upper half of the cover 7 of the pull rod is in the shape of a convex character.

[0073] In this embodiment, the pull rod cap 7 of this shape is more conducive to the scattering of adsorbent material.

[0074] The remaining parts of the precise release device for adsorbent material in this embodiment are the same as those in the above embodiments. For specific details, please refer to the relevant descriptions and effects in the above embodiments for understanding.

[0075] Example 5

[0076] This embodiment, based on the above embodiments, designs another manually controlled device for precise release of adsorbent material. Its structure differs from the above embodiments in that, as follows: Figure 5 As shown, the device also includes a pull rod buckle 11.

[0077] Since the shapes of the vacuum container 5 and the pull rod cover 7 may vary depending on the application, and the mass of the adsorbent material 4 may also vary, in order to ensure the airtightness of the vacuum container 5 and the pull rod cover 7, it is necessary to use the vacuum container quantitative formula to calculate whether additional pull rod clips are needed to fix the pull rod cover 7 and the vacuum container 5.

[0078] The quantitative formula for the vacuum container includes:

[0079]

[0080] Where k1 is the mass of adsorbent material 4, k2 is the mass of pull rod cap 7, μ is the coefficient of friction, S is the cross-sectional area of ​​the capping end of pull rod cap 7, p is the internal and external pressure difference, and g is the gravitational constant.

[0081] If the mass k1 of the adsorbent material 4 calculated according to the formula is less than the actual mass of the adsorbent material 4, then a pull rod clip 11 is needed to fix the pull rod of the pull rod cover 7 to the superconducting container 2. The fixing method is not limited, but it must be a detachable structure, such as a threaded or screw-on structure.

[0082] The remaining parts of the precise release device for adsorbent material in this embodiment are the same as those in the above embodiments. For specific details, please refer to the relevant descriptions and effects in the above embodiments for understanding.

[0083] Example 6

[0084] This embodiment, based on the above embodiments, designs another manually controlled device for precise release of adsorbent material. Its structure differs from the above embodiments in that, as follows: Figure 6 As shown, the vacuum container 5 and the pull rod cover 7 have different shapes, and the structure of this device is suitable for the release of adsorbed materials in the lateral direction.

[0085] The structures described in Examples 1-5 typically involve the release of adsorbed material in a vertical direction. When the structure of the superconducting container 2 is not suitable for installing a vertically oriented vacuum container 5, an alternative approach can be adopted. Figure 6 The lateral release structure described herein mounts the vacuum container 5 on the side of the superconducting container 2.

[0086] In this embodiment, the inner walls of both the vacuum container 5 and the pull rod cap 7 are inclined to prevent the adsorbed material from failing to be released and remaining inside the vacuum container 5 and the pull rod cap 7.

[0087] The remaining parts of the precise release device for adsorbent material in this embodiment are the same as those in the above embodiments. For specific details, please refer to the relevant descriptions and effects in the above embodiments for understanding.

[0088] Example 7

[0089] This embodiment, based on the above embodiments, designs another manually controlled device for precise release of adsorbent material. Its structure differs from the above embodiments in that, as follows: Figure 7 As shown, the superconducting container 2 and the pull rod cover 7 have different shapes, and the device also includes a cover 12, which is suitable for containers with certain requirements for the flatness of the outer surface of the container.

[0090] The structures described in Examples 1-6 typically leave a portion of the tie rod on the container surface, which may have some impact on the daily use of the container. If there are certain requirements for the appearance of the container, or if there is a high sensitivity to protrusions on the outer surface, a different design can be adopted. Figure 7 The structure described in the text.

[0091] In this embodiment, the superconducting container 2 has a recessed structure, and the pull rod of the pull rod cover 7 is located within this recessed structure. The pull rod of the pull rod cover 7 is relatively short to ensure that, after successful release of the adsorbent material, the pull rod of the pull rod cover 7 does not extend beyond the outer surface of the superconducting container 2. After successful release of the adsorbent material, the cover 12 is used to cover the recess of the superconducting container 2, resulting in a relatively smooth surface on the superconducting container. The connection method between the cover 12 and the superconducting container 2 is not limited; it can be a threaded, welded, or snap-fit ​​connection.

[0092] The remaining parts of the precise release device for adsorbent material in this embodiment are the same as those in the above embodiments. For specific details, please refer to the relevant descriptions and effects in the above embodiments for understanding.

[0093] Example 8

[0094] This embodiment aims to disclose the practical application method and process of the adsorbent release of the manually controlled adsorbent material precision release device based on the above embodiment.

[0095] like Figure 8 This demonstrates the installation of a manually controlled, precisely released adsorbent material device provided by this invention within an actual liquid nitrogen storage tank. Figure 8 In the figure, the vacuum space within the double-layered vacuum walls of the liquid nitrogen storage tank is the aforementioned superconducting container 2. Part a of the figure shows the following: Figure 9 The left side shows the installation of the vertical vacuum container 5 using the existing vacuum interface, and as shown... Figure 9 The right side shows the installation of the vertical vacuum container 5 using a dedicated interface. Part b shows... Figure 10 The installation of vacuum container 5 is shown in the lateral direction.

[0096] The specific process of the practical application method for releasing the adsorbent material includes:

[0097] Step S1: Set up a device for precise release of adsorbent material;

[0098] Step S1 specifically includes:

[0099] Step S101: According to the shape and size of the superconducting container 2, change the shape, size, hardness and material of the vacuum container 5. The shape of the vacuum container 5 should conform to the pressure vessel design standard formula.

[0100] Step S102: Calculate whether the pull rod buckle 11 is needed to fix the pull rod cover 7 and the vacuum container 5 using the vacuum container quantitative formula;

[0101] Step S103: Place the adsorbent material 4 into the vacuum container 5 and seal the vacuum container 5 using the pull rod cap 7 and the first sealing ring 6;

[0102] In step S104, the vacuum container 5 is evacuated to a vacuum state through the vacuum port 1, and the vacuum container is fixed in the superconducting container 2 using the cantilever 3.

[0103] Since this invention needs to avoid the adsorbent material from contacting the internal space of the superconducting container 2 under normal pressure or low vacuum / medium vacuum conditions, it is necessary to calculate the pressure difference between the inner and outer containers and the mass of the adsorbent. The mass of the adsorbent is mainly determined by the mass of the pull rod cap 7 and the pressure difference between the inner and outer containers.

[0104] Step S2: Evacuate the superconducting container 2 to a vacuum state;

[0105] Step S3: Pull the lever to seal the cover 7 and release the adsorbent material 4 inside the vacuum container 5.

[0106] If the above methods are implemented as software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this invention, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device, such as a personal computer, server, or network device, to execute all or part of the steps of the methods described in the various embodiments of this invention. The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.

[0107] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
